Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, specifically to a device for adjusting the arc shape of an outward-swinging door of a vehicle and its usage method. Background Technology

[0002] In the field of vehicle manufacturing and repair, the outward-swinging door, as a key component for passenger entry and exit, directly affects the sealing performance, operational stability, and aesthetic appearance of the entire vehicle due to the degree of conformity between its curve and the side panel of the vehicle body. Traditional outward-swinging door curve adjustment processes mostly rely on manual hammering, template comparison, or simple fixtures by operators. This method is highly dependent on the experience and technical proficiency of the operators, lacks scientific and quantitative control methods, and is prone to curve deviations due to human factors. The adjustment process often requires repeated disassembly and trial assembly, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee the consistency and precision of the curve.

[0003] With the diversification of vehicle designs, the curved design of outward-swinging doors is becoming increasingly complex, placing higher demands on the shaping process. In existing technologies, general-purpose tooling equipment has a rigid structure and poor adaptability, making it difficult to quickly adapt to the curve adjustment needs of outward-swinging doors of different vehicle models. While special fixtures developed for specific vehicle models can improve the shaping accuracy to some extent, their development cycle is long and the manufacturing cost is high, making them unsuitable for the modern vehicle production mode of small batches and multiple varieties. In addition, traditional shaping methods are even more inadequate when dealing with doors made of high-strength materials or composite materials, which can easily cause damage to the door surface or stress concentration in the internal structure, affecting the service life and safety of the door. Furthermore, existing tooling cannot achieve shaping of the upper body of the vehicle door; it can only be shaped at the shaping station before being mounted, and then disassembled for shaping after comparison. This operation is time-consuming and labor-intensive.

[0004] Therefore, the existing technology has the following main problems in the process of adjusting the arc of the outward swing door: First, the adjustment accuracy is low and the consistency is poor; second, the operation relies on human experience, which is inefficient; third, the adaptability of general tooling is insufficient, and the cost and cycle of special fixtures are high; fourth, there is a lack of visualization and quantifiable control methods, making it difficult to achieve dynamic fine adjustment. Summary of the Invention To address the problems existing in the prior art, this invention provides a vehicle outward swing door arc adjustment device and its usage method, which can realize visual comparison and rapid and accurate adjustment of the outward swing door arc with the vehicle frame, reduce the dependence on the operator's experience and skills, and improve the consistency of product adjustment quality and production efficiency. The device has a simple structure and is convenient and flexible to operate.

[0005] The technical solution of the present invention is as follows: In a first aspect of the invention, a vehicle outward swing door arc-shaped adjustment device is provided, comprising a connecting beam structure and a clamping mechanism. The connecting beam structure is provided with a support beam, which is disposed on the inner side of the vehicle outward swing door along the length direction of the vehicle outward swing door. The clamping mechanism is provided with an L-shaped adjusting guide rod, one end of which is slidably disposed on the support beam on the side away from the vehicle outward swing door, and the other end of which is provided with a connecting crossbar. The connecting crossbar is disposed on the outer arc-shaped surface of the vehicle outward swing door. The L-shaped adjusting guide rod and the connecting crossbar form a U-shaped structure, the open end of which is disposed on the side of the vehicle outward swing door. The connecting crossbar can move closer to or further away from the vehicle outward swing door along the adjusting guide rod. A clamping assembly is provided on the connecting crossbar, and the clamping assembly and the support beam are symmetrically arranged along the vehicle outward swing door. In some embodiments of the present invention, the support beam is provided with a hook at its top end near the vehicle's outward-swinging door, and the hook is hung on the top of the vehicle's outward-swinging door. In some embodiments of the present invention, a first pad is provided at the top of the support beam near the hook position. The first pad is disposed between the support beam and the vehicle outward swing door, and a rubber plate is provided on the side of the first pad near the vehicle outward swing door. In some embodiments of the present invention, the bottom end of the support beam near the vehicle door is provided with a protruding structure, and the protruding structure is disposed facing the inner side of the vehicle outward swing door.

[0006] In some embodiments of the present invention, a second pad is provided on the end face of the protruding structure facing the inner side of the vehicle outward swing door, and a rubber plate is provided on the side of the second pad near the vehicle outward swing door. In some embodiments of the present invention, the support beam is provided with a sliding groove along its length on the side away from the vehicle's outward swing door, and one end of the adjusting guide rod is provided with a limiting block, which is adapted to slide in a sliding connection with the sliding groove. In some embodiments of the present invention, a rack structure is provided along the length direction at the position where the adjusting guide rod connects to the connecting crossbar, one end of the connecting crossbar is provided with a through hole, the through hole is sleeved on the rack structure, and a snap-fit ​​member is provided outside the through hole, the snap-fit ​​member passing through the through hole and contacting the rack structure. In some embodiments of the present invention, the clamping assembly is provided with a threaded rod, the end of the threaded rod away from the vehicle outward swing door is provided with a handle, the end of the threaded rod near the vehicle outward swing door is provided with a clamping block, and the end of the connecting crossbar away from the adjusting guide rod is provided with a threaded hole, the threaded hole being threadedly connected to the threaded rod. In some embodiments of the present invention, the clamping block is configured as a truncated cone structure, the small circular end of the truncated cone structure is connected to the threaded rod, the large circular end of the truncated cone structure is positioned towards the outward swing door of the vehicle, and the large circular end of the truncated cone structure is provided with an anti-slip structure. In a second aspect of the invention, a method of using a vehicle outward-swinging door arc-adjusting device is provided, comprising: The arc-shaped adjustment device is hung on the top edge of the vehicle's outward-swinging door via a hook, so that the rubber plate on the first pad contacts the inner frame of the vehicle's outward-swinging door, while the lower protruding structure contacts the inner frame of the vehicle's outward-swinging door. Insert the limiting block at one end of the adjusting guide rod into the lower end of the slide groove, push the limiting block to the target adjustment area of ​​the vehicle's outward swing door, control the locking component to move it away from the rack structure, so that the connecting crossbar can slide along the adjusting guide rod. After sliding into place, control the locking component to engage with the rack structure, and adjust the clamping component to the specified position. Rotate the handle to gradually bring the first and second pads into contact with the inner frame of the vehicle's outward swing door and apply pressure. Continuously rotate the handle according to the state of the outward swing door's arc adjustment to gradually adjust the arc of the vehicle's outward swing door to the target shape. After adjusting the vehicle's outward swing door along the chute to an arc shape, rotate the handle to loosen the clamping mechanism and remove the limiting block from the bottom of the chute. Then, remove the support beam from the top edge of the vehicle's outward swing door and move it to a non-construction area.

[0007] One or more technical solutions of the present invention have the following beneficial effects: The present invention provides a vehicle outward swing door arc adjustment device and its usage method, which can be directly installed on the outward swing door of the superstructure for adjustment. This allows the operator to compare and adjust the outward swing door with the vehicle frame during the adjustment process, without having to install and remove the outward swing door multiple times, thus improving work efficiency. The connecting beam structure of this invention is hung on the upper edge of the door body by hooks, and combined with the first pad, the second pad and the rubber plate set at the top and bottom, it realizes the quick and non-destructive installation and stable support of the device, and provides a reliable foundation for the adjustment operation. Its support beam is arranged along the length of the door body to ensure uniform force distribution. The clamping mechanism, through the L-shaped adjusting guide rod, connecting crossbar and clamping component forming a U-shaped structure, achieves the wrapping and precise force application of the target arc from the inside and outside of the door. The sliding connection design of the slide groove and the limiting block allows the clamping mechanism to move easily along the support beam and be precisely fixed in any target area that needs to be shaped, greatly enhancing the adaptability and flexibility of the device and effectively solving the problem of poor compatibility of general tooling. The threaded rod and handle in the clamping assembly form a spiral fine-tuning mechanism. By rotating the handle, the operator can precisely control the magnitude and progress of the pressure applied by the clamping block to the outer arc surface of the door, achieving a gradual and visual adjustment of the arc. This process does not rely on the operator's experience and feel, significantly reducing deviations caused by human factors and ensuring the accuracy and consistency of the adjustment. The anti-slip structure and truncated cone structure at the end of the clamping block not only ensure the stability of the force application process and prevent slippage, but also increase the contact area and avoid damage to the paint surface of the door. In addition, the rack structure on the adjusting guide rod cooperates with the snap-fit ​​on the connecting crossbar to achieve rapid coarse adjustment and instant locking of the position of the connecting crossbar, further improving the adjustment efficiency.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Example 1 In a typical embodiment of the present invention, a device for adjusting the arc shape of a bus outward-swinging door is provided, comprising a connecting beam structure 110 and a clamping mechanism 120. The connecting beam structure 110 is provided with a support beam 112, which is disposed on the inner side of the bus outward-swinging door 201 along the length direction of the bus outward-swinging door 201. The clamping mechanism 120 is provided with an L-shaped adjusting guide rod 121, one end of which is slidably disposed on the side of the support beam 112 away from the bus outward-swinging door 201. The other end of 121 is provided with a connecting crossbar 125, which is located on the outer arc surface of the outward swing door 201 of the bus. The L-shaped adjusting guide rod 121 and the connecting crossbar 125 form a U-shaped structure. The open end of the U-shaped structure is located on the side of the outward swing door 201 of the bus. The connecting crossbar 125 can move closer to or further away from the outward swing door 201 of the bus along the adjusting guide rod 121. The connecting crossbar 125 is provided with a clamping assembly, which is symmetrically arranged with the support beam 112 along the outward swing door 201 of the bus.

[0012] Through the coordinated action of the connecting beam structure 110 and the clamping mechanism 120, the arc of the bus outward swing door 201 is effectively and precisely adjusted. The support beam 112 is arranged on the inner side along the length of the door body, providing a stable and reliable base for the entire adjustment process and ensuring uniform force distribution. The L-shaped adjustment guide rod 121 and the connecting crossbar 125 in the clamping mechanism 120 form a U-shaped structure, creating a clamping space from the inside and outside of the door body, allowing operators to operate and observe intuitively from the outside. The characteristic that the connecting crossbar 125 can move along the adjustment guide rod 121 allows for quick adaptation to the adjustment requirements of different arc segments and different models of the outward swing door 201, greatly improving the versatility and adaptability of the device. The symmetrical arrangement of the clamping component and the support beam 112 ensures the balance and symmetry of the force applied during the adjustment process, effectively avoiding door body twisting or local stress concentration caused by unilateral force, thereby ensuring the accuracy of the arc adjustment and the safety of the door structure. The device body 100 requires no electricity or pneumatic assistance; it can achieve efficient and precise arc shaping solely through its mechanical structure, thereby improving operational flexibility and on-site application convenience.

[0013] In some embodiments of the present invention, the top of the support beam 112 near the bus outward swing door 201 is provided with a hook 115, which is hung on the top of the bus outward swing door 201. This setup enables rapid installation and positioning between the device body 100 and the outward-swinging door 201 of the bus. Operators can easily suspend the device on the upper edge of the door using hooks 115. This process does not require other complex tools or cumbersome fixing operations, greatly saving installation time and improving the preparation efficiency of the adjustment work. Furthermore, the hooks 115 are installed in a non-intrusive manner, avoiding scratches or damage to the door surface and protecting the paint and integrity of the door. At the same time, this suspension method provides a stable and reliable fulcrum for the entire adjustment device, ensuring that the device will not accidentally shift or fall off during subsequent adjustment, thus providing a foundation for precise force application and arc adjustment.

[0014] In some embodiments of the present invention, a first pad 114 is provided at the top of the support beam 112 near the hook 115. The first pad 114 is disposed between the support beam 112 and the outward swing door 201 of the bus. A rubber plate 113 is provided on the side of the first pad 114 near the outward swing door 201 of the bus. The first pad 114 increases the contact area between the support beam 112 and the inner frame of the door, making the pressure distribution more uniform and preventing damage to the internal structure or skin of the door due to excessive pressure. The application of the rubber plate 113 further enhances the protective effect. Its softness can effectively absorb and buffer the local stress generated during the adjustment process, avoiding wear on the door coating or material due to hard contact. The rubber plate 113 also provides excellent anti-slip performance, enhances the friction between the device and the door, prevents relative sliding between the device and the door during the adjustment process, and ensures the effective transmission of adjustment force and the accuracy of the adjustment position. The combination of the first pad 114 and the rubber plate 113 takes into account both protection and functionality, and maintains the integrity of the bus outward swing door 201 to the greatest extent while achieving effective adjustment.

[0015] In some embodiments of the present invention, the bottom end of the support beam 112 near the bus door is provided with a protruding structure, which is arranged facing the inner side of the bus outward swing door 201.

[0016] The protruding structure forms a specific support and positioning point at the bottom of the support beam 112. It is set towards the inner side of the door, so that after the device is suspended, the protruding structure can contact the corresponding part of the inner side of the door and participate in the support and positioning. This setting enhances the stability of the connection between the device and the door, forming a stable layout of hanging on top and supporting on the bottom. It effectively prevents the device from swinging or rotating around the hook 115 during the adjustment process, ensuring the stability and reliability of the adjustment operation. The protruding structure also serves as an auxiliary fulcrum when applying force during adjustment, which helps to more accurately control the direction and degree of deformation of the door's arc.

[0017] In some embodiments of the present invention, a second pad is provided on the end face of the protruding structure facing the inner side of the bus outward swing door 201, and a rubber plate 113 is provided on the side of the second pad near the bus outward swing door 201. The second pad and the rubber plate 113 on it are set on the raised structure at the bottom, which also plays the role of increasing the contact area, distributing pressure evenly, preventing stress concentration from damaging the door, and providing a good anti-slip effect. This optimizes the contact area between the device and the door at the bottom, ensuring that the door can be effectively protected on the entire adjustment contact surface, while ensuring the stable application of the adjustment force.

[0018] In some embodiments of the present invention, the support beam 112 is provided with a sliding groove 111 along the length direction on the side away from the passenger car outward swing door 201, and one end of the adjusting guide rod 121 is provided with a limiting block 122, and the limiting block 122 is adapted to slide and connect with the sliding groove 111.

[0019] The cooperative arrangement of the slide 111 and the limiting block 122 enables the clamping mechanism 120 to be flexibly positioned and moved. The slide 111 is arranged along the length of the support beam 112, allowing the clamping mechanism 120 to slide smoothly within the slide 111 through its limiting block 122. This allows the adjustment point to be easily moved to the target area on the outward swing door 201 where the arc needs to be adjusted, greatly enhancing the adaptability and specificity of the device. There is no need to change tooling or reinstall the device for different adjustment points. The adaptive connection between the limiting block 122 and the slide 111 ensures the stability and guiding accuracy during the sliding process, while preventing the clamping mechanism 120 from accidentally coming out of the slide 111, ensuring the safety and controllability of the operation.

[0020] In some embodiments of the present invention, a rack structure 126 is provided along the length direction at the position where the adjusting guide rod 121 is connected to the connecting crossbar 125. One end of the connecting crossbar 125 is provided with a through hole, which is sleeved on the rack structure 126. A snap-fit ​​member 127 is provided outside the through hole, which passes through the through hole and contacts the rack structure 126.

[0021] The rack structure 126 and the through hole of the snap-fit ​​component 127 form an efficient and reliable quick adjustment and locking mechanism. By pulling out the snap-fit ​​component 127 to disengage it from the rack, the operator can easily move the connecting crossbar 125 along the length of the adjusting guide rod 121, thereby quickly and roughly adjusting the radial position of the clamping assembly relative to the outer arc surface of the door to adapt to the curvature of different parts of the door or the door structure of different thicknesses. After pressing the snap-fit ​​component 127, it moves along the through hole and engages with the rack structure 126, immediately locking the connecting crossbar 125 firmly in the current position to prevent displacement during the adjustment process. This setting simplifies the preparation steps before adjustment, realizes the quick and accurate setting and reliable locking of the position of the connecting crossbar 125, and improves the adjustment efficiency.

[0022] In some embodiments of the present invention, the tightening assembly is provided with a threaded rod 123, and a handle 124 is provided at the end of the threaded rod 123 away from the passenger car outward swing door 201. A tightening block is provided at the end of the threaded rod 123 near the passenger car outward swing door 201. A threaded hole is provided at the end of the connecting crossbar 125 away from the adjusting guide rod 121. The threaded hole is threadedly connected to the threaded rod 123. By rotating the handle 124 to drive the threaded rod 123 to screw in or out of the threaded hole, the pressure applied by the clamping block to the outer surface of the door can be precisely controlled. The threaded drive has a self-locking characteristic, which can ensure that a stable clamping state is maintained after pressure is applied, without the need to continuously apply external force, thus reducing the labor intensity of the operator. The screw fine adjustment method allows for fine and gradual adjustment of the door's arc. The operator can observe the changes in the arc while finely adjusting the handle 124, achieving precise control of the arc shape and significantly improving the accuracy and quality of the adjustment.

[0023] In some embodiments of the present invention, the clamping block is configured as a truncated cone structure, the small circular end of the truncated cone structure is connected to the threaded rod 123, the large circular end of the truncated cone structure is positioned towards the outward swing door 201 of the bus, and the large circular end of the truncated cone structure is provided with an anti-slip structure.

[0024] The truncated cone structure of the clamping block, with its large end facing the door, provides a larger contact area, which helps to disperse the clamping force, reduce local pressure on the door's paint surface, and avoid indentations or damage. The anti-slip structure (such as patterns, rubber coatings, etc.) significantly increases the friction between the clamping block and the door surface, effectively preventing slippage between the clamping block and the door surface during the shaping process, ensuring that the shaping force can be effectively transferred to the door, thereby accurately shaping the curve. In a second aspect of the invention, a method of using a bus outward-swinging door arc-adjustment device is provided, comprising: The arc-shaped adjustment device is hung on the top edge of the bus outward swing door 201 via hook 115, so that the rubber plate 113 on the first pad 114 contacts the inner frame of the bus outward swing door 201, and at the same time the lower protruding structure contacts the inner frame of the bus outward swing door 201. Insert the limiting block 122 at one end of the adjusting guide rod 121 into the lower end of the slide groove 111, push the limiting block 122 to the target adjustment area of ​​the outward swing door 201 of the bus, control the locking piece 127 to move it away from the rack structure 126, so that the connecting crossbar 125 can slide along the adjusting guide rod 121. After sliding into place, control the locking piece 127 to engage with the rack structure 126, and adjust the clamping assembly to the specified position. Rotating handle 124 causes the first pad 114 and the second pad to gradually contact the inner frame of the bus outward swing door 201 and apply pressure. According to the state of the arc adjustment of the outward swing door 201, continuously rotating handle 124 gradually adjusts the arc of the bus outward swing door 201 to the target shape. After adjusting the curve of the bus outward swing door 201 along the slide groove 111, rotate the handle 124 to make the clamping mechanism 120 release the bus outward swing door 201, then remove the limiting block 122 from the lower end of the slide groove 111, and remove the support beam 112 from the upper edge of the door body of the bus outward swing door 201 and move it to a non-construction area.

[0025] The entire method greatly reduces the reliance on the operator's experience and skill level. Through standardized steps and visual operation, operators can complete high-quality arc shaping work using the device provided by this invention, significantly improving the efficiency and consistency of shaping operations, reducing the number of repeated adjustments and disassembly / reinstallation, and making it suitable for various scenarios such as bus manufacturing production lines and after-sales maintenance workshops.

[0026] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
