Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts assembly technology, and in particular to a positioning and fixing device for assembling the rear seat of an electric vehicle. Background Technology

[0002] In the field of electric vehicle manufacturing and repair, the assembly of the rear seat is one of the key processes. The rear seat usually needs to be fixed to the frame, rear horizontal fork, seat cushion bracket and other components by bolts. The assembly accuracy directly affects the safety and comfort of the vehicle. At present, the commonly used rear seat fixing devices in the industry are mostly simple support frames or clamps. Their structure usually includes a fixed base and an adjustable support arm. The support arm abuts against the bottom of the rear seat to achieve initial fixation. The operator then manually aligns the bolt holes and tightens the connecting parts.

[0003] However, the traditional support frame used in the existing technology can only provide rough support in the vertical direction and cannot accurately adjust the horizontal position of the rear seat, which makes it difficult to align the bolt holes and requires operators to repeatedly adjust the position of the rear seat, greatly reducing assembly efficiency.

[0004] To address the aforementioned issues, this utility model provides a positioning and fixing device for assembling the rear seat of an electric vehicle. The device achieves precise horizontal adjustment of the positioning frame through the cooperation of a threaded rod and a threaded tube, ensuring that the positioning frame accurately matches the position of the rear seat mounting plane. After the operator places the rear seat on the positioning frame, the bolt holes of the rear seat and the frame are automatically aligned, eliminating the need for repeated adjustments. Installation can be completed simply by tightening the bolts, significantly reducing assembly time. Utility Model Content

[0005] In order to overcome the problem that in the daily use of traditional electric vehicle rear seat assembly and fixing devices, the traditional support frame can only provide rough vertical support, which makes it impossible to accurately adjust the horizontal position of the rear seat, resulting in difficulties in aligning bolt holes, requiring operators to repeatedly adjust the position of the rear seat, and greatly reducing assembly efficiency.

[0006] The technical solution of this utility model is as follows: a positioning and fixing device for assembling the rear seat of an electric vehicle, comprising a top plate, a first connecting plate, a second connecting plate, a third connecting plate, a positioning component, a fixing component, an adjusting component, and a lifting component. Two sets of symmetrically distributed first connecting plates are arranged below the top plate. One end of the first connecting plate is rotatably connected to the second connecting plate, and one end of the second connecting plate is rotatably connected to the third connecting plate. A positioning component is arranged on one side of the first connecting plate, and a fixing component is arranged on one end of the third connecting plate. An adjusting component is arranged on one side of the top plate. A lifting component is arranged above the positioning component. The positioning component includes a fixing frame, a lifting block, a threaded tube, a threaded rod, a first handle, a bearing, a positioning frame, a connecting rod, and scale markings. A fixing frame is arranged on one side of the first connecting plate. A lifting block is slidably connected to the inner side of the fixing frame. A threaded tube is arranged on the inner side of the lifting block. A threaded rod is threadedly connected to the inner side of the threaded tube. One end of the threaded rod is rotatably connected to the bearing. A positioning frame is fixedly connected to one side of the bearing. A first handle is arranged at the other end of the threaded rod. A connecting rod is arranged on one side of the positioning frame, and the connecting rod passes through the lifting block. Scale markings are arranged on the surface of the connecting rod.

[0007] Preferably, first, fix the two sets of third connecting plates at fixed points symmetrically positioned on the rear horizontal fork of the electric vehicle frame. Bend the angles of the second and first connecting plates to ensure the first connecting plate is perpendicular to the mounting plane of the electric vehicle's rear seat. Move the lifting block to the height of the mounting plane of the electric vehicle's rear seat. Rotate the first handle to drive the threaded rod to rotate. The rotation of the threaded rod causes it to move linearly along the threaded tube, adjusting the horizontal position of the positioning frame. When the positioning frame moves, it drives the connecting rod to move linearly. Observe the scale marks on the connecting rod to determine the adjustment distance of the positioning frame. Adjust the two sets of positioning frames to both sides of the mounting position of the electric vehicle's rear seat. The seat is placed securely above the two sets of positioning brackets. The operator connects the bolts between the rear seat and the rear seat mounting bracket and tightens them to a certain position. At this point, the position of the rear seat is fixed. The first handle is rotated in the opposite direction to move the two sets of positioning brackets out. Then, the connecting bolts between the rear seat and the rear seat mounting bracket are tightened to complete the installation of the rear seat. This device limits the installation position of the electric vehicle's rear seat when it is installed. The operator only needs to place the rear seat on the limiting structure to tighten the bolts at its connection point. There is no need to repeatedly adjust the position of the rear seat, which improves the efficiency of the installation operation of the electric vehicle's rear seat.

[0008] Preferably, the fixing component includes a first fixing plate and a fixing block, with the first fixing plate disposed at the lower end of the third connecting plate and the fixing block disposed below the first fixing plate.

[0009] Preferably, the fixing component also includes a second handle and a first lead screw, with the second handle provided on one side of the fixing block and the first lead screw provided on one side of the second handle.

[0010] Preferably, the fixing assembly also includes a clamping block, a first rubber pad, and a second rubber pad. The clamping block is threaded to the outer side of the first lead screw. The first rubber pad is provided on one side of the clamping block, and the second rubber pad is provided on one side of the first fixing plate.

[0011] Preferably, the adjustment assembly includes a third handle and a second lead screw. The third handle is provided on one side of the top plate, and the second lead screw is provided on the inner side of the top plate. The second lead screw has two opposite threads, and the second lead screw is threadedly connected to two sets of first connecting plates.

[0012] Preferably, the adjustment assembly also includes a limiting rod, with the limiting rod provided on the inner side of the top plate, and the first connecting plate and the limiting rod being slidably connected.

[0013] Preferably, the lifting assembly includes a fourth handle and a third lead screw. The fourth handle is located above the fixed frame, and the third lead screw is located inside the fixed frame. The third lead screw is threadedly connected to the lifting block.

[0014] The beneficial effects of this utility model are:

[0015] First, fix the two sets of third connecting plates at the fixed points symmetrically positioned on the rear horizontal fork of the electric vehicle frame. Bend the angles of the second and first connecting plates to ensure that the first connecting plate is perpendicular to the mounting plane of the electric vehicle's rear seat. Move the lifting block to the height of the mounting plane of the electric vehicle's rear seat. Rotate the first handle to drive the threaded rod to rotate. The rotation of the threaded rod causes it to move linearly along the threaded tube, adjusting the horizontal position of the positioning frame. As the positioning frame moves, it drives the connecting rod to move linearly. Observe the scale marks on the connecting rod to determine the adjustment distance of the positioning frame. Adjust the two sets of positioning frames to both sides of the mounting position of the electric vehicle's rear seat, and place the electric vehicle's rear seat on... Placed securely above the two sets of positioning brackets, the operator connects and tightens the bolts connecting the rear seat and the rear seat mounting bracket to a certain position. At this point, the position of the rear seat is fixed. Turn the first handle in the opposite direction to move the two sets of positioning brackets out, and then continue to tighten the connecting bolts between the rear seat and the rear seat mounting bracket to complete the installation of the rear seat. This device limits the installation position of the electric vehicle's rear seat when installing it. The operator only needs to place the rear seat on the limiting structure to tighten the bolts at its connection point, without having to repeatedly adjust the position of the rear seat, thus improving the efficiency of the electric vehicle rear seat installation operation.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 2This utility model provides an embodiment: a positioning and fixing device for assembling the rear seat of an electric vehicle, including a top plate 1, a first connecting plate 2, a second connecting plate 3, a third connecting plate 4, a positioning component, a fixing component, an adjusting component, and a lifting component. Two sets of symmetrically distributed first connecting plates 2 are arranged below the top plate 1. One end of the first connecting plate 2 is rotatably connected to the second connecting plate 3, and one end of the second connecting plate 3 is rotatably connected to the third connecting plate 4. A positioning component is arranged on one side of the first connecting plate 2, and a fixing component is arranged at one end of the third connecting plate 4. An adjusting component is arranged on one side of the top plate 1, and a lifting component is arranged above the positioning component. The positioning assembly includes a fixed frame 101, a lifting block 102, a threaded tube 103, a threaded rod 104, a first handle 105, a bearing 106, a positioning frame 107, a connecting rod 108, and a scale mark 109. A fixed frame 101 is provided on one side of the first connecting plate 2. A lifting block 102 is slidably connected to the inner side of the fixed frame 101. A threaded tube 103 is provided on the inner side of the lifting block 102. A threaded rod 104 is threadedly connected to the inner side of the threaded tube 103. A bearing 106 is rotatably connected to one end of the threaded rod 104. A positioning frame 107 is fixedly connected to one side of the bearing 106. A first handle 105 is provided at the other end of the threaded rod 104. 5. A connecting rod 108 is provided on one side of the positioning frame 107. The connecting rod 108 passes through the lifting block 102. The surface of the connecting rod 108 is provided with scale marks 109. First, fix the two sets of third connecting plates 4 at the fixed points symmetrically positioned on the rear horizontal fork of the electric vehicle frame. Bend the angle of the second connecting plate 3 and the first connecting plate 2 so that the first connecting plate 2 is perpendicular to the mounting plane of the rear seat of the electric vehicle. Move the lifting block 102 to the height of the mounting plane of the rear seat of the electric vehicle. Rotate the first handle 105 to drive the threaded rod 104 to rotate. The rotation of the threaded rod 104 causes the threaded rod 104 to move linearly along the threaded tube 103, thus leveling the positioning frame 107. Adjust the position. When the positioning frame 107 moves, it drives the connecting rod 108 to move linearly. Observe the scale mark 109 on the connecting rod 108 to determine the adjustment distance of the positioning frame 107. Adjust the two sets of positioning frames 107 to both sides of the electric vehicle's rear seat installation position. Place the electric vehicle's rear seat on top of the two sets of positioning frames 107 and keep it stable. The operator connects the bolts at the connection between the rear seat and the rear seat mounting frame and tightens them to a certain position. At this time, the position of the rear seat is fixed. Turn the first handle 105 in the opposite direction to move the two sets of positioning frames 107 out. Then continue to tighten the connecting bolts between the rear seat and the rear seat mounting frame to complete the installation of the rear seat.

[0023] Please see Figure 3 and Figure 4In this embodiment, the fixing component includes a first fixing plate 201 and a fixing block 202. The lower end of the third connecting plate 4 is provided with the first fixing plate 201, and the fixing block 202 is provided below the first fixing plate 201. The fixing component also includes a second handle 203 and a first lead screw 204. The second handle 203 is provided on one side of the fixing block 202, and the first lead screw 204 is provided on one side of the second handle 203. The fixing component also includes a clamping block 205, a first rubber pad 206, and a second rubber pad 207. The clamping block 205 is threaded to the outer side of the first lead screw 204. The first rubber pad 206 is provided on one side of the clamping block 205, and the second rubber pad 207 is provided on one side of the first fixing plate 201. In use, by rotating the second handle 203, the first lead screw 204 is rotated. The rotation of the first lead screw 204 causes the clamping block 205 to move linearly, thereby clamping the first rubber pad 206 and the second rubber pad 207 at the fixing point of the electric vehicle's rear horizontal fork.

[0024] The adjustment assembly includes a third handle 301 and a second lead screw 302. The third handle 301 is located on one side of the top plate 1, and the second lead screw 302 is located on the inner side of the top plate 1. The second lead screw 302 has two opposite threads and is threadedly connected to two sets of first connecting plates 2. The adjustment assembly also includes a limit rod 303, which is located on the inner side of the top plate 1. The first connecting plates 2 and the limit rod 303 are slidably connected. In use, rotating the third handle 301 drives the second lead screw 302 to rotate. The second lead screw 302 rotates to drive the two sets of first connecting plates 2 to move linearly, adapting to different vehicle widths. The lifting assembly includes a fourth handle 401 and a third lead screw 402. The fourth handle 401 is provided on the top of the fixed frame 101, and the third lead screw 402 is provided on the inner side of the fixed frame 101. The third lead screw 402 and the lifting block 102 are threadedly connected. In use, the fourth handle 401 is rotated to drive the third lead screw 402 to rotate, and the rotation of the third lead screw 402 drives the lifting block 102 to move up and down.

[0025] During operation, the device is first fixed and its foundation adjusted: the two sets of third connecting plates 4 are placed at the fixed points symmetrically positioned on the rear swingarm of the electric vehicle frame. By rotating the second handle 203 in the fixing assembly, the first lead screw 204 is rotated, causing the clamping block 205 to move linearly along the first lead screw 204 until the first rubber pad 206 on one side of the clamping block 205 and the second rubber pad 207 on the side of the first fixing plate 201 are tightly fitted onto the surface of the rear swingarm of the frame, thus completing the fixed connection between the device and the frame; then the adjustment assembly is rotated. The third handle 301 in the component drives the second lead screw 302 to rotate (the surface of the second lead screw 302 is provided with two opposite threads). Under the guidance of the limit rod 303, the two sets of first connecting plates 2 move in opposite directions along the axis of the second lead screw 302 to adjust to match the width of the rear seat mounting plane of the electric vehicle to be assembled. Finally, the fourth handle 401 in the lifting assembly is rotated to drive the third lead screw 402 to rotate, driving the lifting block 102 to move up and down along the inner side of the fixed frame 101 to adjust the first connecting plate 2 to be perpendicular to the rear seat mounting plane.

[0026] Next, the horizontal calibration of the positioning frame 107 is performed: by observing the position of the lifting block 102 after the adjustment of the lifting assembly, it is confirmed that its height is consistent with the height of the rear seat mounting plane; then, the first handle 105 in the two sets of positioning assemblies is rotated respectively, which drives the threaded rod 104 to rotate (the threaded rod 104 is connected to the positioning frame 107 through the bearing 106), so that the threaded rod 104 moves linearly along the axial direction of the threaded tube 103, thereby pushing the positioning frame 107 to move horizontally; when the positioning frame 107 moves, it drives the connecting rod 108 to move synchronously, and the moving distance of the positioning frame 107 is accurately measured by the scale mark 109 set on the surface of the connecting rod 108, ensuring that the two sets of positioning frames 107 move to the preset alignment points on both sides of the rear seat mounting position, forming a horizontal limiting structure for the rear seat mounting plane;

[0027] Finally, the rear seat is assembled and secured: the electric vehicle rear seat to be assembled is placed above the two sets of positioning frames 107. At this time, the bottom of the rear seat is in contact with the surface of the positioning frame 107, and the bolt holes of the rear seat, the rear horizontal fork of the frame, and the seat support are automatically aligned by the horizontal calibration of the positioning frame 107. The operator passes the connecting bolts through the corresponding holes of the rear seat and the frame in sequence, and initially tightens them until the bolt heads are in contact with the bottom of the rear seat. Then, the first handle 105 is rotated in the opposite direction to move the positioning frame 107 out of the space under the rear seat along the direction of the connecting rod 108. Finally, all connecting bolts are tightened to secure the rear seat to the frame. The entire assembly process does not require repeated adjustment of the rear seat position, which significantly improves the assembly efficiency.

[0028] Through the above steps, firstly, fix the two sets of third connecting plates 4 at fixed points symmetrically positioned on the rear horizontal fork of the electric vehicle frame. Bend the angles of the second connecting plate 3 and the first connecting plate 2 so that the first connecting plate 2 and the mounting plane of the electric vehicle's rear seat are perpendicular. Move the lifting block 102 to the height of the mounting plane of the electric vehicle's rear seat. Rotate the first handle 105 to drive the threaded rod 104 to rotate. Use the rotation of the threaded rod 104 to make the threaded rod 104 move linearly along the threaded tube 103 to adjust the horizontal position of the positioning frame 107. When the positioning frame 107 moves, it drives the connecting rod 108 to move linearly. Observe the scale mark 109 on the connecting rod 108 to determine the adjustment distance of the positioning frame 107. Adjust the two sets of positioning frames 107 respectively. 7. Place the electric vehicle's rear seat on both sides of the installation position of the rear seat, and secure it above the two sets of positioning brackets 107. The operator connects the bolts between the rear seat and the rear seat mounting bracket and tightens them to a certain position. At this point, the position of the rear seat is fixed. Turn the first handle 105 in the opposite direction to move the two sets of positioning brackets 107 out. Then continue to tighten the connecting bolts between the rear seat and the rear seat mounting bracket to complete the installation of the rear seat. This device utilizes the limitation of the installation position of the electric vehicle's rear seat during installation. The operator only needs to place the rear seat on the limitation structure to tighten the bolt structure at its connection point, without repeatedly adjusting the position of the rear seat, thus improving the efficiency of the electric vehicle rear seat installation operation.

[0029] 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.
