The mattress is compact in structure, convenient to carry and transport and simple and convenient to use.

The invention discloses a multi-media integrated teaching machine which comprises a blackboard outer frame, a left movable whiteboard, a fixed whiteboard and a right movable whiteboard, wherein the left movable whiteboard, the fixed whiteboard and the right movable whiteboard are embedded in the blackboard outer frame, an electronic whiteboard is connected onto the fixed whiteboard, a multi-media all-in-one machine is connected with a lateral portion of the blackboard outer frame in a closed mode, a projection machine is arranged in the front of the electronic whiteboard, the projection machine is connected with the blackboard outer frame through a support, and a projection face of the projection machine right faces the electronic whiteboard. The electronic whiteboard is connected with the multi-media all-in-one machine through a universal serial bus (USB) line, and the electronic whiteboard is further connected with the projection machine through internal lines. The multi-media all-in-one machine equivalently serves as a controller of the teaching machine and is sealed on the lateral portion of the blackboard outer frame, and the multi-media all-in-one machine is respectively connected with the electronic whiteboard and the projection machine through a built-in line. The multi-media integrated teaching machine is of a multi-media teaching machine integrated structure, the electronic whiteboard and a control section are integrally designed, connection lines between the electronic whiteboard and control section are not exposed, and the multi-media integrated teaching machine is low in failure rate, convenient to install, economic and durable.

The invention provides a skylight beam structure and a car and relates to the technical field of car equipment. The skylight beam structure comprises a skylight beam body provided with a skylight rearbeam, and a reinforcing rib used for fixing a sealing strip is arranged in the length direction of the skylight rear beam. The skylight beam body is further provided with at least two of a positioning hole, an aluminum pipe buckling point, a water discharging pipe and a motor mounting hole. The water discharging pipe is connected with the skylight beam body through injection molding, and the water discharging pipe, a guide rail connecting point, the aluminum pipe buckling point and the motor mounting hole of a skylight are highly integrated, so that assembly and mounting are more convenient.The technical problem that in the prior art, when the skylight is maintained, operation is very inconvenient, and the assembly technique is complex, so that the mounting cost of the car is increased,and the sealing performance of the skylight is poor are solved. The water discharging performance of the skylight beam structure is improved, and the space utilization condition of the skylight is improved.

The invention provides a pure electric-drive portable electric folding bicycle with practicability and portability. The portable electric folding bicycle comprises a handlebar, a front fork, a front wheel, a seat, a framework and a rear wheel, wherein the front wheel is connected to the lower end of the front fork through a front wheel shaft; the front wheel is arranged on a driving motor shaft; a motor is connected with a controller inside the framework through a wire; the controller is used for controlling operation and speed adjustment of the motor; the framework has a hollow structure; the upper part and the lower part of the front end of the framework are connected between the lower part of the handlebar and the upper part of a fork through a handlebar folding fastener and a fork folding fastener respectively; a rear wheel folding fastener is arranged between two parts of the framework; the rear end of the framework is connected with the rear wheel through a rear wheel shaft; a power supply battery is arranged inside the framework; both the motor and the controller are connected with the power supply battery; a braking device is arranged on the outer side of the motor; the braking device is connected with a hand brake on the handlebar; the hand brake is pressed manually, so braking is realized through friction between a braking sheet of the braking device and a wheel hub; a footrest is arranged on the lower part of the front fork; and the seat can be arranged on the middle part of the framework in a folding supported manner.

A suspended ultrasonic cleaning device mainly comprises a housing (9), a vibration bottom plate (6), ultrasonic transducers (8) connected with an ultrasonic generator, and the like. The suspended ultrasonic cleaning device is characterized in that the ultrasonic transducers (8) are mounted on the vibration bottom plate (6) in the sealed housing (9); spaces among the ultrasonic transducers (8) are filled with a sound deadening filler material (4); and the vibration bottom plate (6) is in bonding connection with the ultrasonic transducers (8) through epoxy resin adhesive (5). The suspended ultrasonic cleaning device provided by the invention has the advantages as follows: 1, noise generated by the suspended ultrasonic cleaning device is minimized by adopting the methods of sound deadening, sound absorption and sound insulation; 2, the cleaning space is arbitrary, and the suspended ultrasonic cleaning device can be used for cleaning objects in any container of which the calibre is greater than that of the suspended ultrasonic cleaning device; 3, the matching property is good, that is, the suspended ultrasonic cleaning device can almost be in seamless butt joint with any kitchen water tank to avoid the purchase and installation of another suspended ultrasonic cleaning device; 4 the structure is reasonable; and 5, a better cleaning effect is achieved due to a top-down covering conduction mode.
