Description

Technical Field

[0001] This utility model relates to the field of chassis testing technology, specifically to a support plate for testing the chassis of new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, scissor lifts have become core equipment in the chassis maintenance of new energy vehicles. In actual maintenance scenarios, maintenance personnel use scissor lifts to raise the vehicle to a suitable height to carry out support and inspection work.

[0003] However, existing traditional scissor lifts have significant limitations in application. Due to the diverse specifications and large differences in dimensions of new energy vehicles on the market, traditional scissor lifts, with their relatively fixed support positions, cannot flexibly adapt to the actual needs of different vehicle sizes. In actual maintenance work, repair personnel often need to frequently change lift equipment adapted to different vehicle models, which not only increases the complexity and time cost of the operation process but also reduces the efficiency of maintenance work to some extent. This makes it difficult to fully meet the growing demand for new energy vehicle maintenance and testing, and urgently requires improvement and perfection through technological innovation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a support plate for testing the chassis of new energy vehicles, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A support plate for testing the chassis of a new energy vehicle, including a mounting base;

[0007] A guide frame is fixedly installed on the top surface of the mounting base. A first fixed frame and a second fixed frame are provided on the top surface of the mounting base. A U-shaped bracket is welded to the top surface of both the first fixed frame and the second fixed frame. A mounting plate is rotatably installed on the top surface of the mounting base via a rotating shaft. A hydraulic rod is installed on the top surface of the mounting base.

[0008] The U-shaped bracket is provided with a fixing plate, and connecting blocks are welded to both ends of the fixing plate. The connecting blocks are installed on the U-shaped bracket by bolts. A frame is fixedly installed on the bottom end face of the fixing plate, and a drive motor is installed on the front end face of the frame. A bidirectional lead screw is provided on the output shaft of the drive motor. A guide rod is installed inside the frame, and a support plate body is provided on the fixing plate.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, L-shaped connecting frames are welded to both the front and rear ends of the mounting base. There are a total of six L-shaped connecting frames, which are arranged in a rectangular array relative to the mounting base.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] L-shaped connecting brackets are arranged in a rectangular array at the front and rear ends of the mounting base, providing the mounting foundation for the entire support plate assembly. These L-shaped connecting brackets allow the mounting base to be fixed to the lifting platform of the scissor lift for use.

[0013] Furthermore, guide rails are fixedly installed on the bottom surfaces of both the first and second fixed frames, and the guide rails are slidably sleeved on the guide frame.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The sliding sleeve structure between the guide rail and the guide frame allows the first and second fixed frames to slide smoothly along the guide frame. This design facilitates adjusting the distance between the first and second fixed frames according to the different lengths of the new energy vehicle chassis. In actual testing, different models of new energy vehicle chassis may have different lengths. By sliding the first and second fixed frames on the guide rail, the support spacing of the support plates can be flexibly changed to adapt to chassis of different lengths, improving the versatility and applicability of the support plates and meeting diverse testing needs.

[0016] Furthermore, a mounting block is provided on the output shaft of the hydraulic rod, and the bottom end face of the mounting block is fixedly mounted on the first fixing frame.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The output shaft of the hydraulic rod is fixedly connected to the first fixed frame by an mounting block, enabling the hydraulic rod to drive the first fixed frame to move. When the position of the first fixed frame needs to be adjusted, the hydraulic rod can precisely control the moving distance and speed of the first fixed frame, thereby achieving precise adjustment of the support position of the support plate and improving the accuracy and efficiency of the support plate position adjustment during the testing process.

[0019] Furthermore, a first transmission rod is mounted on the first fixed frame via a pin, and the end of the first transmission rod facing away from the first fixed frame is mounted on the mounting plate via a pin.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The first transmission rod is connected to both the first fixed frame and the mounting plate via pins, forming a movable transmission structure. When the first fixed frame moves under the drive of the hydraulic rod, the first transmission rod transmits the motion of the first fixed frame to the mounting plate, allowing the mounting plate to rotate around the pivot. This transmission structure achieves efficient transmission and conversion of force and motion, transforming linear motion into rotational motion through a simple mechanical connection. This provides the foundation for subsequently moving the second fixed frame, making the entire adjustment process of the support plate more coordinated and smooth.

[0022] Furthermore, a second transmission rod is mounted on the end of the mounting plate opposite to the first transmission rod via a pin, and the end of the second transmission rod opposite to the mounting plate is mounted on the second fixed frame via a pin.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The second transmission rod is connected to the mounting plate and the second fixed frame via pins, forming a complete transmission system together with the first transmission rod and the mounting plate. When the mounting plate rotates around the pivot under the drive of the first transmission rod, the second transmission rod transmits the rotational motion of the mounting plate to the second fixed frame, allowing the second fixed frame to move accordingly along the guide frame. This design achieves the linkage adjustment of the first and second fixed frames. Only the movement of the first fixed frame needs to be controlled by the hydraulic rod, which simultaneously drives the second fixed frame to move synchronously. This greatly simplifies the adjustment operation, improves adjustment efficiency, and allows the support plate to quickly adapt to new energy vehicle chassis of different lengths.

[0025] Furthermore, an I-shaped guide block is welded to the bottom end face of the support plate body. The I-shaped guide block is slidably sleeved on the fixed plate and the guide rod. The I-shaped guide block is threaded onto the bidirectional lead screw.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The sliding sleeve structure between the I-shaped guide block and the fixed plate / guide rod, as well as the threaded connection structure with the bidirectional lead screw, allows the support plate body to slide smoothly on the fixed plate. When the drive motor drives the bidirectional lead screw to rotate, due to the special structure of the lead screw, its threads drive the I-shaped guide block to move along the guide rod. This design allows the position of the support plate body to be adjusted according to the width of the new energy vehicle chassis, achieving width adjustment on top of length adjustment. By controlling the rotation direction and angle of the drive motor, the spacing of the support plate body can be adjusted, thereby better adapting to new energy vehicle chassis of different widths and improving the adaptability and support effect of the support plate to different specifications of vehicle chassis.

[0028] This utility model provides a support plate for chassis testing of new energy vehicles. It has the following features:

[0029] Beneficial effects:

[0030] The sliding sleeve structure of the guide rails on the bottom surfaces of the first and second fixed frames and the guide frame allows the two fixed frames to slide smoothly along the guide frame. This enables the distance between the first and second fixed frames to be flexibly adjusted according to the different lengths of the new energy vehicle chassis, improving the versatility and applicability of the support plate and meeting diverse testing needs.

[0031] The second transmission rod is connected to the mounting plate and the second fixed frame via pins, forming a complete transmission system together with the first transmission rod and the mounting plate. This system enables the coordinated adjustment of the first and second fixed frames. By simply controlling the hydraulic rod to drive the first fixed frame to move, the second fixed frame can move synchronously, greatly simplifying the adjustment operation, improving adjustment efficiency, and allowing the support plate to quickly adapt to new energy vehicle chassis of different lengths.

[0032] The sliding sleeve structure between the I-shaped guide block on the bottom end face of the support plate body and the fixed plate and guide rod, as well as the threaded connection structure with the bidirectional lead screw, allows the support plate body to slide smoothly on the fixed plate. By driving the bidirectional lead screw to rotate through the drive motor, the position of the support plate body can be adjusted according to the width of the new energy vehicle chassis, thereby achieving width adjustment and further improving the adaptability and support effect of the support plate to different specifications of vehicle chassis.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0042] Example 1

[0043] A support plate for testing the chassis of a new energy vehicle includes a mounting base 1;

[0044] A guide frame 102 is fixedly installed on the top surface of the mounting base 1. A first fixed frame 2 and a second fixed frame 201 are provided on the top surface of the mounting base 1. U-shaped brackets 202 are welded to the top surfaces of the first fixed frame 2 and the second fixed frame 201. A mounting plate 108 is rotatably installed on the top surface of the mounting base 1 through a rotating shaft 106. A hydraulic rod 103 is installed on the top surface of the mounting base 1.

[0045] A fixing plate 204 is provided on the U-shaped bracket 202. Connecting blocks 203 are welded to both ends of the fixing plate 204. The connecting blocks 203 are installed on the U-shaped bracket 202 by bolts 205. A frame 303 is fixedly installed on the bottom end face of the fixing plate 204. A drive motor 302 is installed on the front end face of the frame 303. A two-way lead screw 305 is provided on the output shaft of the drive motor 302. A guide rod 304 is installed inside the frame 303. A support plate body 3 is provided on the fixing plate 204.

[0046] L-shaped connecting brackets 101 are welded to both the front and rear ends of the mounting base 1. There are six L-shaped connecting brackets 101 in total, arranged in a rectangular array relative to the mounting base 1. This rectangular array provides the mounting foundation for the entire support plate device. These L-shaped connecting brackets 101 allow the mounting base 1 to be fixed to the lifting platform of the scissor lift for use.

[0047] Guide rails 206 are fixedly installed on the bottom surfaces of both the first fixed frame 2 and the second fixed frame 201. The guide rails 206 are slidably sleeved on the guide frame 102. This sliding sleeve structure between the guide rails 206 and the guide frame 102 allows the first fixed frame 2 and the second fixed frame 201 to slide smoothly along the guide frame 102. This design facilitates adjusting the distance between the first fixed frame 2 and the second fixed frame 201 according to the different lengths of the new energy vehicle chassis. In actual testing, the lengths of different models of new energy vehicle chassis may vary. By sliding the first fixed frame 2 and the second fixed frame 201 on the guide rails 206, the support spacing of the support plates can be flexibly changed to adapt to chassis of different lengths, improving the versatility and applicability of the support plates and meeting diverse testing needs.

[0048] A mounting block 104 is provided on the output shaft of the hydraulic rod 103. The bottom end of the mounting block 104 is fixedly mounted on the first fixed frame 2. The output shaft of the hydraulic rod 103 is fixedly connected to the first fixed frame 2 through the mounting block 104, so that the hydraulic rod 103 can drive the first fixed frame 2 to move. When it is necessary to adjust the position of the first fixed frame 2, the hydraulic rod 103 can precisely control the moving distance and speed of the first fixed frame 2, thereby realizing the precise adjustment of the support position of the support plate, improving the accuracy and efficiency of the support plate position adjustment during the testing process.

[0049] A first transmission rod 105 is mounted on the first fixed frame 2 via a pin. The end of the first transmission rod 105 facing away from the first fixed frame 2 is mounted on the mounting plate 108 via a pin. The first transmission rod 105 is connected to both the first fixed frame 2 and the mounting plate 108 via pins, forming a movable transmission structure. When the first fixed frame 2 moves under the drive of the hydraulic rod 103, the first transmission rod 105 transmits the motion of the first fixed frame 2 to the mounting plate 108, allowing the mounting plate 108 to rotate around the rotating shaft 106. This transmission structure achieves effective transmission and conversion of force and motion, converting linear motion into rotational motion through a simple mechanical connection, providing a foundation for subsequently moving the second fixed frame 201, making the entire adjustment process of the support plate more coordinated and smooth.

[0050] A second transmission rod 107 is mounted on the end of the mounting plate 108 opposite to the first transmission rod 105 via a pin. The end of the second transmission rod 107 opposite to the mounting plate 108 is mounted on the second fixed frame 201 via a pin. The second transmission rod 107 is connected to the mounting plate 108 and the second fixed frame 201 via pins, forming a complete transmission system together with the first transmission rod 105 and the mounting plate 108. When the mounting plate 108 rotates around the rotating shaft 106 under the drive of the first transmission rod 105, the second transmission rod 107 transmits the rotational motion of the mounting plate 108 to the second fixed frame 201, allowing the second fixed frame 201 to move accordingly along the guide frame 102. This design achieves the linkage adjustment of the first fixed frame 2 and the second fixed frame 201. Only the hydraulic rod 103 needs to be controlled to drive the first fixed frame 2 to move, simultaneously achieving the synchronous movement of the second fixed frame 201. This greatly simplifies the adjustment operation, improves adjustment efficiency, and allows the support plate to quickly adapt to new energy vehicle chassis of different lengths.

[0051] Example 2

[0052] To allow for further adjustment based on the width of the car chassis, for example, such as Figures 1 to 3 As shown, this utility model also includes:

[0053] An I-shaped guide block 301 is welded to the bottom surface of the support plate body 3. The I-shaped guide block 301 is slidably sleeved on the fixed plate 204 and the guide rod 304. The I-shaped guide block 301 is threadedly mounted on the double-acting screw 305. The sliding sleeve structure between the I-shaped guide block 301 and the fixed plate 204 and the guide rod 304, as well as the threaded connection structure with the double-acting screw 305, allows the support plate body 3 to slide smoothly on the fixed plate 204. When the drive motor 302 drives the double-acting screw 305 to rotate, due to the special structure of the double-acting screw 305, the threads on it will drive the I-shaped guide block 301 to move along the guide rod 304. This design can adjust the position of the support plate body 3 according to the width of the new energy vehicle chassis, realizing width adjustment on the basis of length adjustment. By controlling the rotation direction and angle of the drive motor 302, the spacing of the support plate body 3 can be adjusted, thereby better adapting to new energy vehicle chassis of different widths and improving the adaptability and support effect of the support plate to different specifications of vehicle chassis.

[0054] Working principle:

[0055] Device installation: The L-shaped connecting frames 101 at the front and rear ends of the mounting base 1 are arranged in a rectangular array. These L-shaped connecting frames 101 are used to fix the mounting base 1 to the lifting platform of the scissor lift, providing a stable installation foundation for the entire support plate device.

[0056] Length adjustment preparation: The guide rails 206 on the bottom end surfaces of the first fixed frame 2 and the second fixed frame 201 are slidably sleeved on the guide frame 102, in preparation for adjusting the distance between the two fixed frames according to the length of the new energy vehicle chassis.

[0057] Drive the first fixed frame 2 to move: The mounting block 104 on the output shaft of the hydraulic rod 103 is fixedly installed on the first fixed frame 2. When the hydraulic rod 103 is started, it can precisely control the first fixed frame 2 to move along the guide frame 102, thereby realizing the precise adjustment of the support position of the support plate.

[0058] Transmitting motion to mounting plate 108: A first transmission rod 105, mounted on the first fixed frame 2 via a pin, has its other end mounted on the mounting plate 108 via a pin. When the first fixed frame 2 moves under the drive of the hydraulic rod 103, the first transmission rod 105 transmits the linear motion of the first fixed frame 2 to the mounting plate 108, causing the mounting plate 108 to rotate around the rotating shaft 106.

[0059] The second fixed frame 201 is moved by a pin: one end of the mounting plate 108 opposite to the first transmission rod 105 is mounted with a second transmission rod 107, and the other end of the second transmission rod 107 is mounted on the second fixed frame 201 by a pin. When the mounting plate 108 rotates, the second transmission rod 107 transmits the rotational motion to the second fixed frame 201, causing the second fixed frame 201 to move accordingly along the guide frame 102, thereby realizing the linkage adjustment of the first fixed frame 2 and the second fixed frame 201, completing the adjustment of the support plate in the length direction to adapt to new energy vehicle chassis of different lengths.

[0060] Width Adjustment: The I-shaped guide block 301 on the bottom end face of the support plate body 3 is slidably sleeved on the fixed plate 204 and the guide rod 304, and is simultaneously threaded onto the double-acting screw 305. When the drive motor 302 is started, the double-acting screw 305 is driven to rotate. The threads on the double-acting screw 305 cause the I-shaped guide block 301 to move along the guide rod 304, thereby causing the support plate body 3 to slide on the fixed plate 204. This allows for width adjustment of the support plate to accommodate different widths of new energy vehicle chassis, enabling the support plate body 3 to support the vehicle chassis.
