DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] See also Figure 1 to Figure 7 As shown, a car repair lying board with a braking function includes a side frame 1, a rotating wheel 5, a fixed wheel 6 and a main board 7. The side frame 1 includes a brake 2, a protective cover 3 and a bracket 4; the side frame 1 has two parts respectively installed on both sides of the main board 7, the rotating wheel 5 is installed at one end of the side frame 1 and is at the bottom of the side frame 1, the fixed wheel 6 is installed at the other end of the side frame 1 and is also at the bottom of the side frame 1, the brake 2 is installed at the center of the side frame 1, the protective cover 3 is installed on the upper surface of the side frame 1, the bracket 4 is installed at both ends of the side frame 1 and can move up and down on the side frame 1, one end of the bracket 4 is connected to the fixed wheel 6, and the other end is connected to the rotating wheel 5.

[0023] The device supports the human body through the main board 7, the side frame 1 is used to install the rotating wheel 5 and the fixed wheel 6, the rotating wheel 5 is used to release the direction constraint of the main board 7, the brake 2 is a hydraulic structure, used to control the rotation of the fixed wheel 6, and stop the main board 7 by locking the fixed wheel 6. The bracket 4 is used to adjust the height between the main board 7 and the rotating wheel 5 and the fixed wheel 6, and the protective cover 3 is used to prevent the human body from being stabbed by the sharp parts of the bracket 4 and the brake 2.

[0024] See also Figure 1~Figure 4 As shown, the brake 2 includes a knob 21, a connecting tube 22 and a brake pad 23. The knob 21 is installed on the top of the brake 2 and is rotatably connected to the brake 2. The brake pad 23 is installed on the fixed wheel 6. One end of the connecting tube 22 is connected to the bottom of the brake 2, and the other end is connected to the brake pad 23.

[0025] The knob 21 is used to facilitate maintenance personnel to control the brake 2 when lying flat. The connecting pipe 22 is used to transmit the hydraulic power of the brake 2 to the brake pad 23 and ensure that the brake pad 23 is always connected to the brake pad 23 when the bracket 4 adjusts the height of the main board 7. The brake pad 23 stops the entire fixed wheel 6 by increasing the contact friction with the fixed wheel 6.

[0026] See also Figure 4 As shown, the knob 21 includes a threaded column 211 and a piston 212 . The threaded column 211 is arranged at the bottom of the knob 21 and rotatably engaged with the top of the brake 2 . The piston 212 is arranged inside the brake 2 and fixedly connected to the threaded column 211 .

[0027] The threaded column 211 is engaged with the brake 2 so that the knob 21 can move up and down on the brake 2 by rotating. When the knob 21 moves downward, the piston 212 squeezes the liquid in the brake 2, and the hydraulic pressure is transmitted to the brake pad 23 through the connecting pipe 22. When the knob 21 moves upward, the piston 212 increases the space in the brake 2, and the brake pad 23 no longer gets stuck on the fixed wheel 6.

[0028] See also Figure 3~Figure 6 As shown, the brake pad 23 includes a telescopic column 231, a spring 232 and a movable clamp 233. The movable clamp 233 is arranged opposite to and connected to the brake pad 23. The telescopic column 231 is arranged between the movable clamp 233 and the brake pad 23, and the spring 232 is surrounded on the outside of the telescopic column 231.

[0029] The telescopic column 231 is used to prevent the spring 232 from falling off from between the movable clamp 233 and the brake pad 23. When the brake pad 23 contracts and squeezes the fixed wheel 6, the spring 232 is compressed. When the brake pad 23 releases the fixed wheel 6, the compressed spring 232 is reset, pushing the movable clamp 233 away from the brake pad 23 in the reverse direction and directing the liquid in the brake 2 back into the brake 2.

[0030] See also Figure 2~Figure 6 As shown, the bracket 4 includes a mounting groove 41, a latch 42 and a socket 43. The mounting grooves 41 are arranged at both ends of the side frame 1 and are engaged with the bracket 4. The socket 43 is arranged on the bracket 4. The latch 42 passes through the side surface of the side frame 1 and the socket 43 to fix the bracket 4 in the mounting groove 41.

[0031] The mounting groove 41 is used to provide guiding positioning for the bracket 4. The bracket 4 adjusts its height on the main board 7 by engaging the pin 42 and the socket 43, so as to adjust the distance between the fixed wheel 6 and the rotating wheel 5 and the main board 7, ensuring that the lying board can adapt to automobile chassis of different heights.

[0032] See also Figure 1~Figure 5As shown, the rotating wheel 5 includes a first interlocking frame 51, a longitudinal rotating shaft 52 and a first transverse rotating shaft 53. One end of the longitudinal rotating shaft 52 is connected to the bottom of the bracket 4 at one end of the side frame 1, and the other end is connected to the top of the first interlocking frame 51. The first transverse rotating shaft 53 is installed on the first interlocking frame 51 and rotates coaxially with the rotating wheel 5.

[0033] The first interlocking frame 51 enables the rotating wheel 5 fixed on the first interlocking frame 51 to rotate around the longitudinal rotating axis 52 through the longitudinal rotating axis 52. The first transverse rotating axis 53 is used to install the rotating wheel 5. The rotating wheel 5 changes its direction according to the force direction exerted by the auto repair personnel, so that the auto repair lying board can adjust the forward direction.

[0034] See also Figure 1 to Figure 6 As shown, the fixed wheel 6 includes a second interlocking frame 61, a brake disc 62 and a second transverse rotating shaft 63. The second interlocking frame 61 is connected to the bottom of the bracket 4 at the other end of the side frame 1. The second transverse rotating shaft 63 is installed at the bottom of the second interlocking frame 61. The brake disc 62 rotates coaxially with the fixed wheel 6.

[0035] The second engaging frame 61 is used to install the brake disc 62 and the fixed wheel 6. Since the wheel thickness of the fixed wheel 6 is relatively large, the brake pad 23 directly acts on the fixed wheel 6 to exert a relatively large pressure. If the pressure is not enough, it will affect the fixing effect of the brake 2 on the main board 7. Therefore, the brake disc 62 is provided to replace the fixed wheel 6 to contact the brake pad 23.

[0036] See also Figure 1 to Figure 7 As shown, the main board 7 includes a sub-board 71, a pillow 72, a support rod 73 and a slide groove 74. The sub-board 71 is installed on the side of the main board 7, the support rod 73 connects the main board 7 and the sub-board 71, the pillow 72 is arranged on the sub-board 71, and the slide groove 74 is arranged on the upper surface of the main board 7.

[0037] The auxiliary plate 71 is connected to the main plate 7 through a support rod 73 and can be adjusted. The pillow 72 is used to prop up the head of the maintenance personnel. By adjusting the distance between the auxiliary plate 71 and the main plate 7, the auto repair lying board can be suitable for maintenance personnel of different heights, thereby improving the versatility of the lying board.

[0038] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
