[0001] The utility model relates to the technical field of automobile engineering, in particular to an automobile engineering maintenance auxiliary device. Background Art

[0002] Automobile engineering includes the maintenance of automobiles, and during the process of automobile maintenance, maintenance mats are needed as auxiliary supplies. When repairing an automobile, the automobile needs to be lifted up, or a maintenance area with a ditch needs to be opened. However, when the number of automobiles that need to be repaired is relatively large, some automobiles that do not require complicated repairs require mechanics to lie under the car for simple repairs.

[0003] For example, a Chinese patent with publication number CN202805172U discloses a special maintenance pad for automobile engineering, which includes a support plate, a lighting device, and a tool box. The support plate includes a fixed plate and a rotating plate. The fixed plate and the rotating plate are connected by hinges. The upper parts of the fixed plate and the rotating plate are both provided with sponge pads, and the upper parts of the sponge pads are provided with protective sleeves. The lower parts of the fixed plate and the rotating plate are both provided with universal wheels. A tool box is provided on one side of the fixed plate, and lighting devices are provided on both sides of the front of the fixed plate. The lighting device includes a lighting lamp, a lamp holder, and a movable joint. The lighting lamp and the lamp holder are connected by a movable joint. Beneficial effects: The structural design is reasonable and practical, the conception is ingenious and novel, and the use is simple and convenient. Regardless of the intensity of the external light, the chassis of the car can be repaired conveniently, the maintenance personnel are not easily fatigued, and the maintenance work can be completed by one person. The support plate can be folded, which is more convenient to carry. In actual use, the following problems still exist.

[0026] like Figure 3 , Figure 4 As shown, the mobile light source 5 includes a turntable 51, the bottom surface of the turntable 51 is rotatably connected to the top surface of the front end of the maintenance plate 1, the top surface of the turntable 51 is fixedly connected to a lamp holder 52, the inside of the lamp holder 52 is rotatably connected to a rotating shaft 53, the outer surface of the rotating shaft 53 is fixedly connected to a light source 54, and the outer surface of the light source 54 is rotatably connected to the inner side of the lamp holder 52.

[0027] A light source 54, a lamp holder 52 and a rotating shaft 53 are provided. The rotating shaft 53 allows the light source 54 to be rotated freely on the lamp holder 52, so that the illumination angle of the light source 54 can be adjusted. After the adjustment, the angle of the light source 54 can be limited to avoid the situation where the angle of the light source is changed arbitrarily after adjustment.

[0028] like Figure 3 , Figure 4 As shown, a through hole 56 is formed on the outer surface of the lamp holder 52 , a nut 57 is threadedly connected inside the through hole 56 , a spring 58 is fixedly connected to the end of the nut 57 , and a limiting ball 59 is fixedly connected to the end of the spring 58 .

[0029] A spring 58 and a limiting ball 59 are provided. When the light source 54 is rotated by contraction of the spring 58 , the limiting ball 59 is driven to contract in the through hole 56 , so that the light source 54 can smoothly adjust its angle.

[0030] like Figure 3 , Figure 4 As shown, a plurality of groups of limiting holes 55 distributed in a circular array are provided on an outer surface of one side of the bottom end of the light source 54 , and the inside of the limiting holes 55 is movably engaged with the outer surface of the limiting ball 59 .

[0031] Limiting holes 55 are provided. When the light source 54 rotates, the arc surface of the limiting ball 59 is squeezed and retracted into the through hole 56. After rotating to another set of limiting holes 55, the rebound force of the spring 58 bounces the limiting ball 59 back to the limiting hole 55, so that the adjustment angle of the light source 54 can be limited without applying force.

[0032] like Figure 5 As shown, the adjustment support plate 6 includes a base plate 61, the bottom surface of the base plate 61 is fixedly connected to the top surface of the rear end of the maintenance plate 1, a motor 66 is fixedly installed at the rear end of the base plate 61, a movable groove is opened on the top surface of the base plate 61, a ball screw 67 is rotatably connected inside the movable groove and one end of the ball screw 67 is fixedly connected to the output end of the motor 66, and a screw connector 68 is threadedly connected to the outer surface of the ball screw 67.

[0033] A ball screw 67 and a screw connector 68 are provided. When the ball screw 67 rotates, the screw connector 68 converts the rotary motion into linear motion, so that the ball screw 67 moves horizontally on the surface of the ball screw 67 .

[0035] Furthermore, the opposite surfaces of the two supports 63 are rotatably connected with a round rod 65 , and the outer surface of the round rod 65 is fixedly connected with two groups of adjustment blocks.

[0036] A backrest 64 and a round rod 65 are provided. When a maintenance worker prepares to enter under the vehicle for maintenance, the backrest 64 is rotated with the help of the round rod 65, so that the inclination angle of the backrest can be adjusted, so that maintenance workers of different body shapes can use it.

[0037] like Figure 5 As shown, the top surfaces of the two adjustment blocks are fixedly connected with a support plate 64 , the bottom surface of the support plate 64 is fixedly connected with a bidirectional hinged rod 69 , and the other end of the bidirectional hinged rod 69 is fixedly connected to the top surface of the screw rod connector 68 .

[0038] A bidirectional hinged rod 69 is provided. When the screw rod connector 68 is displaced, the bidirectional hinged rod 69 can be hinged and rotated after being pushed, thereby pushing the back plate 64 to tilt, and providing angle support for the back plate 64 after the tilting is completed.

[0039] The working principle of the utility model is as follows: the maintenance personnel first lies on the maintenance board 1 with his back in contact with the backrest 64, and then the motor 66 is started to drive the ball screw 67 to rotate, and the screw connector 68 converts the rotary motion into a linear motion, so that it moves horizontally on the surface of the ball screw 67. When the screw connector 68 moves, the two-way hinged rod 69 can be hinged and rotated after being pushed, thereby pushing the backrest 64 to tilt. The backrest 64 rotates with the help of the round rod 65, so as to adjust the tilt angle of the backrest, so that maintenance personnel of different body shapes can use it, and provide angle support for the backrest 64 after the tilting is completed, and then with the help of the moving wheel 2 The maintenance personnel can enter the bottom of the lifted vehicle, the searchlight 4 provides basic lighting, and the two groups of hydraulic support rods 3 ensure the safety of the personnel. When performing maintenance, the maintenance personnel can rotate the light source 54, and rotate the lamp holder 52 with the help of the rotating shaft 53. When the light source 54 rotates, the contraction of the spring 58 drives the limiting ball 59 in the through hole 56 to contract, so that the light source 54 can smoothly adjust the angle, and the arc surface of the limiting ball 59 is squeezed and retracted into the through hole 56. After rotating to another group of limiting holes 55, the rebound force of the spring 58 bounces the limiting ball 59 back to the limiting hole 55, so that the adjustment angle of the light source 54 can be limited without applying force.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
