Problems solved by technology

[0002] In the prior art, there are multiple physical buttons on the hand controller, including a rising button and a falling button. By pressing the rising button, the electric motor can be controlled. The lifting table rises, and the electric lifting table can be controlled to descend by pressing the down button. Since multiple physical buttons need to be set at a certain distance, this will cause the overall size of the entire hand controller in the prior art to be too large, thereby increasing the manufacturing cost. cost

Embodiment 1

[0060] refer to Figure 1 to Figure 8 As shown, the hand controller for electric lifting table in this embodiment includes a housing 100 and a main control board 200, the housing 100 includes a base 110 and a cover 120, the main control board 200 is arranged in the housing 100 and fixed on the base 110, the casing 100 in this embodiment runs through a partially exposed roller 700 that is used to control the lifting of the electric lift table, that is, the roller 700 is installed through the cover 120, and the main control board 200 is connected to the rotation angle conversion of the roller 700. An encoder that generates electrical signals, and the main control board 200 controls the lifting of the electric lifting table according to the electrical signals. In this way, when using the hand controller, the lifting control of the electric lifting table can be realized by rolling the roller 700 in the forward and reverse directions, thereby saving the setting of the up button and...

Embodiment 2

[0077] Such as Figure 9 to Figure 10 As shown, compared with Embodiment 1, the difference of this embodiment is that the rotary encoder 300 is welded and fixed on the main control board 200, one end of the rotating shaft 710 is connected with the input sleeve 310 and rotates synchronously, and the other end is correspondingly provided with a switch 210, the rotating shaft 710 in this embodiment has a certain degree of elasticity, so as to realize the elastic installation of the roller 700, so that after pressing the roller 700, the other end of the rotating shaft 710 can deform and move and trigger the setting switch 210, canceling the pressing of the roller 700 Finally, the rotating shaft 710 resets under its own elasticity and drives the roller 700 to reset, and the overall structure is relatively simple.

[0078] In order to horizontally limit the other end of the rotating shaft 710 to prevent the rotating shaft 710 from breaking due to excessive force when rolling the rol...

Embodiment 3

[0080] Such as Figure 11 to Figure 12 As shown, compared with Embodiment 1 and Embodiment 2, the difference of this embodiment is that the encoder is a grating encoder 400, and the grating encoder 400 includes an infrared transmitter 410 and an infrared receiver 420 arranged oppositely, and the base 110 is also provided with a second bracket that runs through the main control board 200. The second bracket includes a fixed frame and a floating frame 1100. The fixed frame and the floating frame 1100 are arranged oppositely. 210 is set corresponding to the boss 1101, and the fixed frame includes two fixed pillars 1200 arranged at intervals, the infrared receiver 420 is located between the two fixed pillars 1200, one end of the rotating shaft 710 is sleeved with a torsion spring 1300, and the two ends of the torsion spring 1300 are respectively The hook is supported on two fixed pillars 1200, and one end of the rotating shaft 710 is rotatably matched with the mounting hole on the...

Abstract

The invention discloses a hand controller for an electric lifting table and an electric lifting table, and aims to solve the technical problem that the overall size of a hand controller is large due to the fact that the number of keys is large in the prior art. The hand controller for the electric lifting table comprises a shell and a main control board arranged in the shell; the shell is provided with a rolling wheel used for controlling the electric lifting table to ascend and descend, the main control board is connected with an encoder used for converting the rotation angle of the rolling wheel into electric signals, and the main control board controls the electric lifting table to ascend and descend according to the electric signals. In addition, the invention further discloses an electric lifting table which comprises a table top plate and the hand controller for the electric lifting table; and the hand controller for the electric lifting table is installed on the bottom face of the table top plate.

Description

【Technical field】 [0001] The invention relates to the technical field of electric lifting tables, in particular to a hand controller for electric lifting tables and an electric lifting table. 【Background technique】 [0002] In the prior art, there are multiple physical buttons on the hand controller, and the multiple physical buttons include a rising button and a falling button. By pressing the rising button, the electric lifting table can be controlled to rise, and by pressing the falling button, the electric lifting table can be controlled to descend. Since a plurality of physical buttons need to be arranged at a certain distance, this will lead to a relatively large overall size of the entire hand controller in the prior art, thereby increasing the manufacturing cost. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a hand controller for an electric lifting table and ...
