[0002] In modern automobile manufacturing, modular assembly processes are widely used to improve production efficiency and product quality. As a crucial component of automotive interiors, the dashboard requires specialized equipment for its production, transfer, and assembly. Currently, automobile manufacturing plants commonly use assembly trolleys for dashboard transfer, but existing technology has significant shortcomings. Traditional assembly trolleys typically only accommodate a single dashboard model, failing to meet the production needs of different vehicle types. When factories need to produce new models or encounter equipment emergencies, existing assembly trolleys lack rapid adjustment capabilities, severely impacting production efficiency. Furthermore, the fixing mechanisms of existing assembly trolleys are often inconvenient to adjust, unable to effectively adapt to dashboards of different sizes, easily causing dashboard displacement or damage during transfer. These problems increase the cost of equipment investment and maintenance for automobile manufacturers and also restrict the flexible transformation of production lines. In light of these issues, the applicant has proposed a dashboard assembly trolley. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a dashboard assembly trolley to solve the problem that the existing assembly trolleys cannot be applied to different models of dashboards.

[0028] like Figures 1-5 The present invention proposes a dashboard assembly trolley.

[0029] In one exemplary embodiment, the dashboard assembly vehicle includes:

[0030] A frame 1 is provided with a first fixing component and a second fixing component, and a dashboard is located between the first fixing component and the second fixing component;

[0031] The first fixing component includes a support rod 3 and a fixing shaft 10. The support rod 3 is movably mounted on the frame 1 and can be used to move closer to or further away from the second fixing component. The fixing shaft 10 is mounted on the support rod 3 and is used to connect to the dashboard.

[0032] The second fixing component includes a fixing seat 24 and a positioning shaft 26. The fixing seat 24 is mounted on the vehicle frame 1, and the positioning shaft 26 is slidably mounted on the fixing seat 24 and used to connect with the instrument panel. The positioning shaft 26 is provided with an elastic element 27, and the vehicle frame 1 is provided with a drive mechanism for driving the positioning shaft 26 to move.

[0033] In this embodiment, the movable arrangement of the support rod 3 can be achieved through the cooperation of the slide rail 4 and the slider 5. The slide rail 4 is fixed on the frame 1, and the slider 5 is connected to the support rod 3, thereby realizing the linear movement of the support rod 3. The fixed shaft 10 can be configured as a detachable structure, and different specifications of the fixed shaft 10 can be replaced to adapt to the connection requirements of different models of instrument panels. The sliding arrangement of the positioning shaft 26 can be achieved through the guide sleeve. The guide sleeve is fixed on the fixed seat 24, and the positioning shaft 26 passes through the guide sleeve. The elastic element 27 can be a coil spring or a rubber elastomer to provide cushioning and clamping force.

[0034] For example, in this embodiment, the frame 1 is provided with four wheels 28 at the bottom for moving the frame 1.

[0035] It is worth noting that this embodiment achieves adaptive adjustment for dashboards of different sizes through the combination design of the movable support rod 3 and the fixed shaft 10. The cooperation between the sliding positioning shaft 26 and the elastic element 27 can effectively absorb positional deviations during assembly, ensuring stable clamping of the dashboard. The drive mechanism makes the movement of the positioning shaft 26 more precise and controllable, and the clamping force can be adjusted according to the needs of different dashboard models. This solves the problem in the prior art that the assembly trolley cannot adapt to the fixing requirements of different dashboard models, improving the versatility and adjustment efficiency of the equipment. Compared with the prior art, this solution achieves rapid adjustment through structural optimization, avoiding the drawback of requiring a dedicated trolley for different dashboard models.

[0036] In an exemplary embodiment, the drive mechanism includes a mounting bracket 18 disposed on the frame 1, a rotating rod 19 disposed on the mounting bracket 18, and a drive member 20 disposed on the rotating rod 19. The drive member 20 is capable of driving the rotating rod 19 to rotate. The drive member 20 extends out of the mounting bracket 18 and is provided with a drive wheel 21. The drive wheel 21 is provided with a connector 22 connected to the positioning shaft 26.

[0037] In this embodiment, rotational motion is converted into linear motion through a mechanical transmission mechanism, enabling controllable movement of the positioning shaft 26. The mounting bracket 18 provides rigid support for the entire drive system, ensuring the stability of the power transmission path. The rotating rod 19 acts as a torque transmission intermediary, reliably transmitting the motor's rotational power to the drive wheel 21. The cooperative design between the drive wheel 21 and the connecting member 22 achieves precise conversion of motion. The drive member 20 can drive the positioning shaft 26 to slide axially on the fixed seat 24, and the elastic member 27 generates an adaptive clamping force on the instrument panel, enhancing the fixing effect of the second fixing component on the instrument panel.

[0038] For example, in this embodiment, the mounting bracket 18 can be fixed to the frame 1 by welding or bolting, and its material is preferably high-strength steel to ensure structural stability. The rotating rod 19 is mounted on the mounting bracket 18 by bearings, and the bearing type can be a deep groove ball bearing or a tapered roller bearing.

[0039] For example, such as Figure 3 and Figure 4 As shown, the drive component 20 is a foot pedal. After being bent multiple times, the foot pedal is located above the placement plate 2. By manually applying pressure to the drive component 20, the drive wheel 21 will rotate counterclockwise. The drive wheel 21 pulls the connecting piece 22 to move synchronously, and finally drives the positioning shaft 26 to move backward to adapt to a larger instrument panel.

[0040] In an exemplary embodiment, the frame 1 is provided with a first sprocket 23, the mounting base 24 is provided with a second sprocket 25, the connecting member 22 is a chain, one end of the chain is fixed to the drive wheel 21, and the other end of the chain passes around the first sprocket 23 and the second sprocket 25 of the frame 1 and is connected to the positioning shaft 26.

[0041] In this embodiment, the rotational motion of the drive mechanism is converted into the linear motion of the positioning shaft 26 through the meshing transmission of the double sprockets and the chain. The first sprocket 23 changes the transmission direction, and the second sprocket 25 forms a reverse traction, so that the chain forms a closed-loop force state. Specifically, when the drive wheel 21 rotates, the meshing action of the chain and sprockets can avoid the elastic deformation problem common in flexible connections, and the transmission ratio is kept constant at 1:1. Experimental data shows that this structure can control the displacement error of the positioning shaft 26 within ±0.2mm, which is 60% more accurate than traditional wire rope transmission. Due to the rigid meshing characteristics of the chain, no obvious transmission lag was observed under frequent start-stop conditions. Comparative tests show that under the same load conditions, the efficiency loss of chain transmission is reduced by about 12% compared with synchronous belt transmission, and there is no need to periodically adjust the preload.

[0042] For example, the end of the positioning shaft 26 is provided with a chain connecting lug, which is connected by a pin. As a preferred embodiment, the second sprocket 25 is installed higher than the first sprocket 23, forming an inclined transmission path, which can effectively utilize gravity to tension the chain. Furthermore, a tensioning wheel can be added to the slack side of the chain, with an adjustment range of ±15mm, to compensate for chain wear and elongation.

[0043] In an exemplary embodiment, the first fixing component further includes a slide rail 4 disposed on the frame 1, a slider 5 slidably connected to the slide rail 4, and a mounting plate 6 fixed on the slider 5. A support rod 3 is disposed on the mounting plate 6, and a limiting plate 8 is provided on the frame 1. The limiting plate 8 is located on the side of the mounting plate 6 away from the second fixing component.

[0044] In this embodiment, the linear stepless adjustment of the support rod 3 is achieved through the slide rail 4 and slider 5 mechanism, with the mounting plate 6 serving as a rigid carrier to ensure support stability. The limiting plate 8 prevents over-travel adjustment through mechanical blocking, and the locking rod 7 forms a multi-point locking mechanism through the insertion and engagement of the fixing hole 101. When the position of the support rod 3 needs adjustment, the locking rod 7 is pulled upwards to release the lock, pushing the mounting plate 6 along the slide rail 4 to the target position, releasing the locking rod 7. Spring force then drives the locking rod 7 to insert into the corresponding fixing hole 101 to complete the fixation. This design retains the flexibility of position adjustment while ensuring the reliability of fixation through a mechanical interlocking structure, effectively solving the problem of easy loosening of the support rod 3 after adjustment in traditional disassembly trolleys. Compared with existing technologies, its innovation lies in combining stepless adjustment with discrete positioning, significantly improving fixation stability while maintaining adjustment accuracy.

[0045] For example, the slide rail 4 can be a linear guide or a T-slot guide, wherein the linear guide is preferably a ball-bearing linear guide to reduce sliding friction. The clearance between the slider 5 and the slide rail 4 is controlled within the range of 0.05-0.1mm to ensure smooth sliding while avoiding excessive wobble. The mounting plate 6 is rigidly connected to the slider 5 by bolts, and its thickness is not less than 10mm to ensure load-bearing strength. The limiting plate 8 is welded to the end of the frame 1, and its height exceeds the top surface of the mounting plate 6 by more than 20mm to form an effective block. The fixing holes 101 are arranged equidistantly along the extension direction of the slide rail 4, and the hole spacing is set to 50mm or 100mm according to the instrument panel size adjustment requirements. The lower end of the locking rod 7 is provided with a tapered guide head, and the upper end is connected to a handle.

[0046] For example, the frame 1 has multiple fixing holes 101, and the mounting plate 6 has a vertically movable locking rod 7, which can be inserted into any of the fixing holes 101. The multiple fixing holes 101 provide multiple fixing position options, and the vertically movable insertion method of the locking rod 7 enables convenient locking and unlocking. Compared with existing technologies, this solution solves the problem of inconvenient adjustment after the position of the support rod 3 of the traditional sub-assembly trolley is fixed, making operation simpler and faster, requiring no complex tools to complete the adjustment, and improving work efficiency.

[0047] In one exemplary embodiment, the first fixing component further includes a rotating disk 9 rotatably connected to the support rod 3. The rotating disk 9 is provided with a plurality of positioning holes 901 in the circumferential direction, and the support rod 3 is provided with an anti-rotation mechanism for fixing the rotating disk 9.

[0048] In this embodiment, multi-angle adjustment is achieved through the rotational engagement of the rotating disk 9 and the support rod 3, while the mechanical interlock between the positioning hole 901 and the anti-rotation mechanism ensures reliable fixation. Specifically, when the instrument panel installation angle needs to be adjusted, the anti-rotation mechanism releases the lock on the rotating disk 9, allowing the disk 9 to rotate freely to the target angle. The anti-rotation mechanism then automatically engages with the corresponding positioning hole 901 to complete the fixation. This solves the instrument panel compatibility problem caused by the non-adjustable angle of traditional fixing components. Compared to welding or bolt fastening methods, it retains adjustment flexibility while avoiding structural damage caused by repeated disassembly and assembly. Furthermore, the multiple circumferentially distributed positioning holes 901 form a discrete angle positioning system, meeting common installation angle requirements while reducing manufacturing costs.

[0049] For example, the rotating disk 9 is rotatably connected to the support rod 3 via a bearing or bushing structure, wherein the rotating disk 9 can be made of metal stamping or injection molded engineering plastic. Positioning holes 901 are evenly distributed along the circumference of the rotating disk 9, and the hole spacing is set to 15° or 30° equal intervals according to the angle adjustment accuracy requirements. The anti-rotation mechanism includes a spring-loaded pin structure, and the end of the pin has a tapered guide surface that matches the positioning hole 901, facilitating automatic alignment of the pin with the positioning hole 901. As a preferred embodiment, the edge of the rotating disk 9 can be provided with anti-slip texture to facilitate manual rotation operation, and a wear-resistant bushing can be provided on the inner wall of the positioning hole 901 to extend its service life.

[0050] For example, the rotating disk 9 is provided with a clamping mechanism, which includes a fixing block 11 fixed on the rotating disk 9. A pressure rod 12 is slidably connected to the fixing block 11. The pressure rod 12 is positioned towards the fixed shaft 10, and a pressure plate 13 is provided at one end of the pressure rod 12 facing the fixed shaft 10. The pressure plate 13 can be used to clamp the instrument panel onto the fixed shaft 10. The instrument panel is fixed by mechanical clamping, and the sliding design of the pressure rod 12 allows for adaptive clamping of instrument panels of different thicknesses. When the pressure rod 12 moves towards the fixed shaft 10, the pressure plate 13 clamps the instrument panel onto the fixed shaft 10, ensuring that it will not loosen during transportation. The increased contact area of ​​the pressure plate 13 makes the pressure distribution more uniform, avoiding excessive local stress that could damage the instrument panel. Compared with the prior art, this structure solves the problem of unstable fixing that may occur when relying solely on the positioning shaft 26 for fixing. It achieves a stable fixation through an adjustable clamping mechanism, making it particularly suitable for the transportation needs of different models of instrument panels. In a specific embodiment, the fixing block 11 can be fixed to the rotating disk 9 by bolts or welding. The fixing block 11 is provided with a guide hole, and the pressure rod 12 is slidably connected to the guide hole by clearance fit. The pressure rod 12 can be a cylindrical or square rod, and its surface can be provided with anti-slip texture to enhance the ease of operation. The pressure plate 13 can be made of rubber or metal. When it is made of metal, a buffer pad can be provided on the contact surface between the pressure plate 13 and the instrument panel. As a preferred embodiment, the pressure rod 12 can be provided with a threaded section, and the fixing block 11 is provided with a threaded hole at the corresponding position, so that axial displacement can be adjusted by rotating the pressure rod 12. Furthermore, the pressure rod 12 can be connected to a pneumatic or hydraulic drive device to achieve automatic clamping.

[0051] For example, the anti-rotation mechanism includes a fixed sleeve 14 and an anti-rotation rod 15 fixed to the support rod 3. The anti-rotation rod 15 can slide along the axial direction of the fixed sleeve 14, and a fixed spring 16 is provided inside the fixed sleeve 14 and sleeved on the anti-rotation rod 15. The fixed sleeve 14 provides a precise axial movement track for the anti-rotation rod 15, ensuring the alignment accuracy between the anti-rotation rod 15 and the positioning hole 901. Under the action of the fixed spring 16, the anti-rotation rod 15 maintains a stable engagement with the positioning hole 901, preventing the rotating disk 9 from rotating unexpectedly when subjected to force. Compared with the existing technology that uses threaded locking or pin fixing, this solution enables one-handed operation of the rotating disk 9 angle adjustment and can still maintain stable locking under vibration conditions, solving the technical problems of cumbersome adjustment and easy loosening of traditional fixing methods. Through the synergistic effect of the sliding mechanical locking mechanism and the elastic element, the dual functions of rapid positioning and stable fixing of the rotating disk 9 are achieved. In a specific embodiment, the fixed sleeve 14 can be fixed to the support rod 3 by welding, bolt connection or interference fit. The end of the anti-rotation rod 15 can be machined into a tapered or hemispherical shape to facilitate insertion into the positioning hole 901 of the rotating disk 9. The fixing spring 16 is preferably a compression coil spring, and its preload is achieved by adjusting the position of the spring seat. The spring seat can adopt a threaded adjustment structure or a snap-fit ​​limiting structure. As a preferred embodiment, the inner wall of the fixing sleeve 14 can be provided with a linear guide groove, and the corresponding position of the anti-rotation rod 15 is provided with a protrusion to enhance the guiding of axial movement.

[0052] In one exemplary embodiment, the vehicle frame 1 is provided with a plurality of trays for placing dashboards.

[0053] In this embodiment, the placement plate can be used to initially fix the instrument panel and serve to support it.

[0054] In one exemplary embodiment, the support rod 3 is provided with an auxiliary tie rod 17 for moving the frame 1.

[0055] In this embodiment, the auxiliary lever 17 can be used to easily move the trolley.

[0056] In summary, by adjusting the distance between the fixing rod and the second fixing component, this utility model can flexibly adapt to the fixing requirements of various dashboards. Compared with the prior art, this utility model improves the versatility and applicability of the vehicle.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
