Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts assembly technology, and in particular to an auxiliary support device for assembling the front of an electric vehicle to prevent tipping. Background Technology

[0002] In the production process of electric vehicles, the assembly of the front end requires the precise assembly of components such as headlights, dashboard, and steering mechanism. In the existing technology, the assembly of the front end is usually supported by a simple bracket or fixed workbench. The process is as follows: manually move the front end to the bracket → manually adjust the angle → multiple people work together to fix it → complete the assembly.

[0003] However, traditional supports often use double-column or single-point support structures. When the front of the vehicle is turned or torque is applied, the device is prone to tipping over due to the shift of the center of gravity, which can cause damage to the workpiece or injury to personnel. This risk is even higher in the assembly of large electric vehicle fronts. Furthermore, the front of the vehicle needs to be frequently adjusted to adapt to different assembly processes. Traditional devices do not have an automatic turning function and require 2-3 workers to manually lift and turn the device, which is labor-intensive and inefficient.

[0004] Therefore, to address the aforementioned issues, an auxiliary support device for assembling the front of an electric vehicle that prevents tipping is proposed. This device forms a triangular support structure through three sets of support components. Utilizing the principle of triangle stability, it effectively resists the overturning moment when the front of the vehicle flips or when torque is applied. By controlling the first micro-motor of any set of support components, the top plate can be flipped. During the assembly of the front of the electric vehicle, only one person is needed to complete the flipping operation, improving the efficiency of the assembly work and significantly reducing the need for additional manpower. Utility Model Content

[0005] In order to overcome the problems of insufficient anti-tipping capacity and the need for additional personnel to stabilize the vehicle during the daily use of traditional electric vehicle front assembly support devices, which waste manpower.

[0006] The technical solution of this utility model is as follows: an auxiliary support device for assembling the front of an electric vehicle to prevent tipping, comprising a base plate, a top plate, a support assembly, a fixing assembly, and a lifting assembly. Three sets of support assemblies arranged in a circular array are provided above the base plate. The top plate is provided at the upper end of the support assembly. The fixing assembly is provided above the top plate. The lifting assembly is provided below the top plate. The support assembly includes a first ball joint, a square tube, a toothed rail frame, a fixing plate, a first micro motor, a gear, and a second ball joint. The first ball joint is provided above the base plate. The square tube is provided above the first ball joint. The toothed rail frame is slidably connected to the inner side of the square tube. The fixing plate is provided on one side of the square tube. The first micro motor is provided on one side of the fixing plate. The gear is provided on the other side of the fixing plate. The gear is located at the slot position opened on the side of the square tube. The gear and the toothed rail frame are meshed and connected. The second ball joint is provided at one end of the toothed rail frame. The second ball joint and the top plate are interconnected.

[0007] Preferably, the top plate is supported by a triangular support structure consisting of three sets of first ball joints, square tubes, gear rails, and second ball joints. This triangular support structure provides stability, preventing the entire device from tipping over. The three-point support provides excellent anti-overturning capability, making it particularly suitable for operations involving applied torque. Simultaneously, by activating the corresponding first micro motor, the gear rotates, causing the gear rail to slide inside the square tube. This, in turn, adjusts the height of the second ball joint at the corresponding point. The change in the position of the second ball joint causes the corresponding position of the top plate to rotate around the axis of the connecting line of the other two sets of second ball joints. This allows for the rotation and adjustment of the fixed electric vehicle head assembly. During the assembly of the electric vehicle head, only one person is needed to complete the rotation, improving the efficiency of the assembly work and significantly reducing the need for additional manpower.

[0008] Preferably, the fixing assembly includes a lifting frame and a connecting frame, with the lifting frame located above the top plate and the connecting frame located above the lifting frame.

[0009] Preferably, the fixing component also includes a second micro motor, a first lead screw and a moving plate. The second micro motor is provided on one side of the connecting frame, and the first lead screw is provided at the output end of the second micro motor. The first lead screw has two opposite threads, and two sets of moving plates are connected to the outer thread of the first lead screw.

[0010] Preferably, the fixing component also includes a damper and a flexible clamping plate, with the damper provided on one side of the moving plate and the flexible clamping plate provided on the other side of the damper.

[0011] Preferably, the lifting assembly includes a lifting motor and a threaded rod. The lifting motor is located below the top plate, and the output end of the lifting motor is provided with a threaded rod, which is threadedly connected to the lifting frame.

[0012] Preferably, a rotating assembly is provided below the base plate. The rotating assembly includes a worm gear, a fixed frame, and a base. The worm gear is provided below the base plate, the fixed frame is provided below the worm gear, and the base is provided below the fixed frame.

[0013] Preferably, the rotating assembly also includes a worm gear, a third micro motor, and casters. The worm gear is provided on the outer side of the worm wheel, and the worm gear and worm wheel are meshed together. The third micro motor is provided at one end of the worm gear, and multiple sets of casters are provided below the base.

[0014] Preferably, the first micro motor, the second micro motor, the third micro motor, and the lifting motor all have built-in electromagnetic brakes for braking after the motor is powered off.

[0015] The beneficial effects of this utility model are:

[0016] The top plate is supported by a triangular support structure consisting of three sets of first ball joints, square tubes, gear rails, and second ball joints. This triangular support structure provides stability and prevents the entire device from tipping over. The three-point support provides excellent anti-overturning capability and is especially suitable for operations involving applied torque. Simultaneously, by activating the corresponding first micro motor, the gear rotates, which in turn causes the gear rail to slide inside the square tube. This, in turn, adjusts the height of the second ball joint at the corresponding point. The change in the position of the second ball joint causes the corresponding position of the top plate to rotate around the axis of the connecting line of the other two sets of second ball joints. This allows for the rotation and adjustment of the fixed electric vehicle head assembly. During the assembly of the electric vehicle head, only one person is needed to complete the rotation, improving the efficiency of the assembly work and significantly reducing the need for additional manpower.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 and Figure 2 This utility model provides an embodiment of an auxiliary support device for assembling the front of an electric vehicle to prevent tipping over. The device includes a base plate 1, a top plate 2, support components, fixing components, and a lifting component. Three sets of support components arranged in a circular array are disposed above the base plate 1. The top plate 2 is disposed above the support components, the fixing component is disposed above the top plate 2, and the lifting component is disposed below the top plate 2. The support components include a first ball joint 101, a square tube 102, a gear rail frame 103, a fixing plate 104, a first micro motor 105, a gear 106, and a second ball joint 107. The first ball joint 101 is disposed above the base plate 1, and the square tube 102 is disposed above the first ball joint 101. The gear rail frame 103 is slidably connected to the inner side of the square tube 102. The fixing plate 104 is disposed on one side of the square tube 102, and the first micro motor 105 is disposed on one side of the fixing plate 104. The gear 106 is located on the side of the square tube 102. At the slot position, gear 106 and gear rail frame 103 are meshed and connected. One end of gear rail frame 103 is provided with a second ball joint 107, which is connected to the top plate 2. The top plate 2 is supported by a triangular support structure composed of three sets of first ball joints 101, square tube 102, gear rail frame 103 and second ball joint 107. The triangular support structure has stability and prevents the device from tipping over. The three-point support provides excellent anti-overturning ability and is especially suitable for applying torque. At the same time, by starting the corresponding first micro motor 105, the gear 106 is driven to rotate. The rotation of gear 106 drives gear rail frame 103 to slide inside square tube 102, thereby driving the height of the second ball joint 107 at the corresponding point to be adjusted. The change in the position of the second ball joint 107 causes the corresponding position of the top plate 2 above to rotate around the axis of the connecting line of the other two sets of second ball joints 107, thereby rotating and adjusting the fixed electric vehicle head workpiece above.

[0025] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, the fixing assembly includes a lifting frame 201 and a connecting frame 202. The lifting frame 201 is disposed above the top plate 2, and the connecting frame 202 is disposed above the lifting frame 201. The fixing assembly also includes a second micro motor 203, a first lead screw 204, and a moving plate 205. The second micro motor 203 is disposed on one side of the connecting frame 202, and the output end of the second micro motor 203 is provided with the first lead screw 204. The first lead screw 204 has two opposite threads, and the outer thread of the first lead screw 204 is connected to... The device is equipped with two sets of movable plates 205. The fixing assembly also includes a damper 206 and a flexible clamping plate 207. The damper 206 is provided on one side of the movable plate 205, and the flexible clamping plate 207 is provided on one side of the damper 206. In use, the second micro motor 203 is started to drive the first lead screw 204 to rotate. The rotation of the first lead screw 204 drives the two sets of movable plates 205 to move linearly, thereby driving the two sets of dampers 206 and flexible clamping plates 207 to move linearly, and clamping the workpiece at the front of the electric vehicle.

[0026] The lifting assembly includes a lifting motor 301 and a threaded rod 302. The lifting motor 301 is located below the top plate 2, and the output end of the lifting motor 301 is equipped with a threaded rod 302. The threaded rod 302 is threadedly connected to the lifting frame 201. In use, starting the lifting motor 301 drives the threaded rod 302 to rotate, which in turn moves the lifting frame 201 up and down, adjusting the height of the fixed electric vehicle front workpiece. The rotating assembly includes a worm gear 401, a fixed frame 402, and a base 403. The worm gear 401 is located below the bottom plate 1, the fixed frame 402 is located below the worm gear 401, and the base 403 is located below the fixed frame 402. The rotating assembly also... It includes a worm gear 404, a third micro motor 405, and casters 406. The worm gear 404 is located on the outer side of the worm wheel 401, and the worm gear 404 and the worm wheel 401 are meshed together. The third micro motor 405 is located at one end of the worm gear 404. Multiple sets of casters 406 are located below the base 403. In use, the worm gear 404 driven by the third motor rotates, which in turn drives the worm wheel 401 to rotate, which in turn drives the base plate 1 to rotate, thereby adjusting the rotation of the fixed electric vehicle head workpiece. The first micro motor 105, the second micro motor 203, the third micro motor 405, and the lifting motor 301 all have built-in electromagnetic brakes for braking after the motor is powered off.

[0027] During operation, the base plate 1 serves as the basic load-bearing component, with three sets of support components arranged in a circular array above it. Each set of support components consists of a first ball joint 101, a square tube 102, a gear frame 103, a fixing plate 104, a first micro motor 105, a gear 106, and a second ball joint 107. The first ball joint 101 is fixed to the surface of the base plate 1, and the bottom end of the square tube 102 is rotatably connected to the first ball joint 101. The gear frame 103 is slidably embedded in the inner cavity of the square tube 102. The fixing plate 104 is vertically welded to the side wall of the square tube 102, and the first micro motor 105 is installed on the outside of the fixing plate 104, with its output shaft passing through the fixing plate 104 and co-located with the gear 106. The shaft is fixedly connected, and the gear 106 meshes with the gear frame 103 through the slot opened in the side wall of the square tube 102; the top of the gear frame 103 is rotatably connected to the bottom surface of the top plate 2 through the second ball joint 107; the three sets of support components form a triangular support structure, which uses the principle of triangle stability to resist the overturning moment when the front of the car is overturned or when torque is applied; when it is necessary to adjust the angle of the top plate 2, any one of the first micro motors 105 is started to drive the gear 106 to rotate, which drives the gear frame 103 to extend and retract along the square tube 102, and the displacement of the second ball joint 107 causes the top plate 2 to rotate with the axis of the line connecting the other two sets of second ball joints 107 as the center, so as to realize the adjustment of the front angle of the car under single-person operation;

[0028] A fixed assembly is installed above the top plate 2, including a lifting frame 201, a connecting frame 202, a second micro motor 203, a first lead screw 204, a moving plate 205, a damper 206, and a flexible clamping plate 207. The bottom end of the lifting frame 201 is slidably connected to the top plate 2, and the top end is vertically fixed to the connecting frame 202. The second micro motor 203 is installed on the side wall of the connecting frame 202, and its output shaft is coaxially fixed to the first lead screw 204. The surface of the first lead screw 204 has two reverse threads, which are threaded to two sets of moving plates 205 respectively. The bottom surface of the moving plate 205 is slidably engaged with the top surface of the lifting frame 201, and the damper 206 and the flexible clamping plate 207 are sequentially arranged on its inner side. Assembly When the second micro motor 203 is started, it drives the first lead screw 204 to rotate, which drives the two sets of moving plates 205 to move in opposite directions. After the damper 206 buffers the clamping force, the flexible clamping plate 207 flexibly fixes the workpiece at the front of the car. A lifting assembly is set at the center of the bottom surface of the top plate 2, including a lifting motor 301 and a threaded rod 302. The lifting motor 301 is fixed to the bottom surface of the top plate 2, and its output shaft is coaxially fixed to the threaded rod 302. The bottom end of the threaded rod 302 is threadedly connected to the top surface of the lifting frame 201. When the lifting motor 301 is started, it drives the threaded rod 302 to rotate, which can drive the lifting frame 201 to lift vertically and adjust the height of the workpiece at the front of the car to adapt to different assembly processes.

[0029] A rotating assembly is located at the center of the bottom surface of the base plate 1, including a worm gear 401, a fixed frame 402, a base 403, a worm 404, and a third micro motor 405. The top surface of the worm gear 401 is coaxially fixed to the bottom surface of the base plate 1. The top end of the fixed frame 402 is rotatably connected to the bottom surface of the worm gear 401, and the bottom end is perpendicularly welded to the top surface of the base 403. The third micro motor 405 is mounted on the top surface of the base 403, and its output shaft is coaxially fixed to the worm 404. The worm 404 meshes with the worm gear 401 for transmission. A caster wheel 406 is provided on the bottom surface of the base 403. A rotating vehicle is required. When the head is in the correct orientation, the third micro motor 405 is activated to drive the worm gear 404 to rotate, which in turn drives the base plate 1 and top plate 2 to rotate horizontally as a whole through the worm wheel 401, thus achieving rotation adjustment. The first micro motor 105, the second micro motor 203, the third micro motor 405, and the lifting motor 301 all have built-in electromagnetic brakes, which automatically lock the output shaft when the power is off to prevent load slippage. This device improves the anti-overturning ability through the triangular support structure, and combined with the electric tilting, lifting, and rotating functions, it enables a single person to efficiently complete each process of the head assembly, significantly reducing the manpower requirement.

[0030] Through the above steps, the top plate 2 is supported by a triangular support structure composed of three sets of first ball joints 101, square tube 102, gear rail frame 103, and second ball joint 107. The triangular support structure has stability, preventing the entire device from tipping over. The three-point support provides excellent anti-overturning ability, and is especially suitable for operations that apply torque. At the same time, by starting the corresponding first micro motor 105, the gear 106 is driven to rotate. The rotation of the gear 106 causes the gear rail frame 103 to slide inside the square tube 102, thereby adjusting the height of the second ball joint 107 at the corresponding point. The change in the position of the second ball joint 107 causes the corresponding position of the top plate 2 above to rotate around the axis of the connecting line of the other two sets of second ball joints 107, thereby rotating and adjusting the fixed electric vehicle head workpiece above. During the assembly of the electric vehicle head, only one person is needed to complete the rotation, which improves the efficiency of the electric vehicle head assembly work and significantly reduces the need for additional manpower.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
