Problems solved by technology

However, due to the influence factors of slope / temperature / door opening angle, the hovering function of the door cannot be guaranteed under reasonable extreme working conditions, or when the door is manually opened and closed under different working conditions, a very light manual operation force is required
Therefore, it is necessary to add an adjustable electromagnetic brake to the driving mechanism. During the whole process of opening and closing the door, it is controlled by the ECU to automatically change the internal resistance of the mechanism, so as to realize the hovering of the door under various working conditions and the appropriate manual force for opening and closing the door. Currently, The braking torque of the brake in the electric strut / drive mechanism is usually a fixed value, which cannot be adjusted, resulting in a constant internal resistance of the electric strut / drive mechanism, which leads to the limit of working conditions after hovering and electric / manual functions in various working conditions on flat slopes. In some conditions (such as uphill, downhill, side slope, etc.), it is easy to have abnormal opening and closing of the door, and even some electric struts / drive mechanisms on the market do not have brakes, so that at room temperature, the door can only hover at various angles in the flat slope state. When going up or downhill at normal temperature, abnormal situations such as large-angle rebound / drop of the door will seriously affect the electric / manual opening and closing of the door, and it is also easy to cause the door to fall / bounce and cause user injury and other abnormal conditions

Embodiment 1

[0021] The electric strut electromagnetic brake is mainly divided into a power-on type electromagnetic brake and a power-off type electromagnetic brake. The whole electromagnetic brake is an integral type, with small dimensions and small space occupation, which can meet the assembly requirements of different occasions.

[0022] like figure 1 and figure 2 As shown, it is an energized electromagnetic brake, including a stator 100, a coil 200, a coil frame 300, a housing 400, an armature pressing piece 500, a friction assembly and a spline shaft 600, and the coil 200 is wound on the coil frame 300 to form a coil assembly assembly And assembled to the inside of the stator 100, in order to ensure the reliability of the winding and installation of the coil 200, as an optimization, the coil frame 300 has an interference fit with the inner boss of the stator 100 through its inner hole or the boss at the end of the coil frame 300 and the One end of the stator 100 is fitted with a hol...

Embodiment 2

[0025] This embodiment is a power-off type electromagnetic brake, and most of the structure of this embodiment is the same as that of Embodiment 1, such as image 3 As shown, the difference is that the electric strut electromagnetic brake also includes a spring 900, wherein one of the armature pressing pieces 500 next to the coil 200 is changed to a larger armature 1001, and one end of the large armature 1001 is connected to the spring 900, The other end of the spring 900 is placed inside the hole of the stator 100. In addition, the large armature 1001 is also provided with a pawl anti-rotation structure 501, and a slot 402 matching the pawl anti-rotation structure 501 is provided in the housing 400. Here, the coil 200 In the power-off state, due to the existence of the spring 900, the spring 900 generates pressure on the large armature 1001 by itself and transmits it to the transmission ring gear 700 and the friction plate 800. When the spline shaft 600 rotates, it drives the ...

Abstract

The invention belongs to the technical field of electric supporting rods, and provides an electric supporting rod electromagnetic brake. The electric supporting rod electromagnetic brake comprises a stator, a coil, a coil frame, a shell, an armature pressing sheet, a friction assembly and a spline shaft, wherein the coil is wound on the coil frame to form a coil assembly and assembled in the stator, the armature pressing sheet and the friction assembly are assembled in the shell and located on the right part of the stator, and the spline shaft transversely penetrates through the stator, the armature pressing sheet and the friction assembly and is connected with the friction assembly through a spline. The electric supporting rod electromagnetic brake has the advantages that the brake torque can be adjusted according to different working conditions and different voltages output by an ECU; it is ensured that the internal resistance in an electric supporting rod/a driving mechanism is adjustable, and the functions of electric/manual opening and closing, hovering and the like of a vehicle door under the various working conditions are met when the electric supporting rod/driving mechanism is assembled on the whole vehicle; when the brake works, the brake adjustment is rapid, the response is fast, and the noise is low during operation; the mechanism is small in boundary dimension, small in occupied space and capable of meeting the assembly requirements of different occasions.

Description

technical field [0001] The invention belongs to the technical field of electric struts, and relates to an electromagnetic brake for electric struts. Background technique [0002] With the development of automobile automation and intelligence, the demand for automatic door opening and closing mechanisms of automobiles is increasing, which greatly improves the user's car experience and enhances the convenience of users. The mechanism has high practicability, realizes the automatic opening and closing of the car door, and is convenient for people to travel. However, due to the influence factors of slope / temperature / door opening angle, the hovering function of the door cannot be guaranteed under reasonable limit conditions, or when the door is manually opened and closed under different conditions, a very light manual operation force is required. Therefore, it is necessary to add an adjustable electromagnetic brake to the driving mechanism. During the whole process of opening an...
