Description

Technical Field

[0001] This application relates to the technical field of automotive sunroofs, and in particular to impact-resistant and deformation-resistant automotive sunroof guide rails. Background Technology

[0002] Car sunroofs play an important role in improving interior lighting and ventilation, but they also face various challenges during use. First, cars inevitably encounter emergencies or poor road conditions while driving, leading to collisions that may affect the normal operation of the sunroof and its rails.

[0003] In the event of a serious car accident, vehicle doors often become deformed, preventing rescuers from opening them properly. In such situations, the sunroof becomes a crucial emergency escape and rescue route. To reduce the difficulty of rescue and ensure the sunroof maintains its structural integrity during a collision, sunroofs with impact-resistant deformation properties are needed. For example, a shock-resistant and cushioning sunroof guide rail (approval number CN215793120U) includes first and second guide rails, each with rubber buffer pads and a hollow anti-arc plate on its upper and lower surfaces, respectively. The arc plate is a hollow structure running through the front and back, made of angle steel. The rubber pads absorb most of the gravitational force and deformation during impact, improving impact resistance; the hollow arc plate enhances bending and torsional resistance, protecting the internal structure, thereby improving the user experience and extending the lifespan.

[0004] However, the aforementioned existing technologies have obvious limitations in dealing with collision impact forces. They rely solely on the combination structure of rubber pads and hollow arc plates for passive buffering, that is, they rely entirely on the physical properties of these two components to absorb and offset the impact force, lacking an active force relief or graded buffering mechanism.

[0005] When a vehicle encounters a high-intensity collision (such as a high-speed rear-end collision or a severe side impact), the instantaneous impact force often far exceeds the elastic deformation limit of the rubber pad and the structural bearing capacity threshold of the hollow arc plate. At this time, the combination of the two is difficult to completely dissipate the impact force, and the unabsorbed residual impact force will directly act on the main body of the guide rail, which can easily cause irreversible deformation or even structural damage to the guide rail.

[0006] Based on this, and given the above viewpoints, there is still room for improvement in existing automotive sunroof rails. Summary of the Invention

[0007] To solve the above-mentioned technical problems, this application provides an impact-resistant and deformation-resistant automotive sunroof guide rail, adopting the following technical solution: An impact-resistant and deformation-resistant automotive sunroof guide rail includes two parallel tracks.

A linkage plate corresponding to the bidirectional screw one is installed on the pressing plate, and the corresponding bidirectional screw is connected to the linkage plate through a threaded connection. A bevel gear two that meshes with bevel gear one is installed at the end of the bidirectional screw near the rotating shaft.

[0014] Preferably, the correction component includes a correction block mounted on a movable block. A rectangular groove is provided inside the correction block, and an adjustment block is slidably disposed inside the rectangular groove. A guide slope is provided symmetrically along the height direction of the correction block at the end of the adjustment block away from the movable block. A correction connecting block is symmetrically disposed along the height direction of the correction block, and the correction connecting block is slidably disposed through the correction block. A lifting block that cooperates with the guide slope is provided on the side of the correction connecting block near the rectangular groove.

[0015] Preferably, the leveling component includes a rubber strip on the side of the moving block away from the straightening block, a leveling block mounted on the rubber strip, a reciprocating block slidably mounted through the moving block and connected to the leveling block, a rotating connecting rod mounted on the rotating shaft, a swing rod mounted on the rotating connecting rod via a hinge, and the end of the swing rod away from the rotating connecting rod mounted on the reciprocating block via a hinge.

[0032] The following is in conjunction with the appendix Figures 1 to 10 This application will be described in further detail.

[0033] This application discloses an impact-resistant and deformation-resistant automotive sunroof guide rail. Through the coordinated operation of three steps—correction and repositioning, secondary shaping, and stress leveling—the sunroof guide rail can be actively corrected and repositioned.

[0034] Example 1: Reference Figure 1 and Figure 2 The impact-resistant and deformation-resistant car sunroof guide rail includes two parallel tracks 1. The top of each track 1 has a mounting groove 11 for placing the sunroof. Sliding grooves 12 are formed on opposite surfaces of the tracks 1. Connecting brackets 2 are mounted on both ends of the same side of each track 1. A top support mechanism 3 for opening the tracks 1 is also provided between the two tracks 1. A storage groove 21 for holding the top support mechanism 3 is formed on opposite surfaces of the connecting brackets 2. The top support mechanism 3 includes: There are two movable blocks 31, each corresponding to one of the tracks 1, and they are slidably disposed inside the sliding groove 12. An adjustment shaft 32 for adjusting the distance between the two movable blocks 31 is installed between them.

[0035] The correction component 33 is mounted on the moving block 31 and is used to correct the track 1.

[0036] The leveling component 34 is installed on the side of the moving block 31 away from the straightening component 33, and is used to level a portion of the straightened track 1.

[0037] In actual operation, the correction component 33 can accurately act on the key parts of the deformed track 1, and efficiently reset it by applying directional force, effectively eliminating the deformation problems such as twisting and displacement of the track 1 caused by external force or long-term use. On this basis, the moving block 31 can perform a fine secondary shaping operation along the surface of the reset track 1. With its specific contour design and pressure adjustment function, it can further optimize the shape accuracy of the track 1, ensuring that the geometric parameters of the reset track 1 meet the preset standards, and fundamentally consolidate the reset effect.

[0038] Subsequently, the leveling component 34 will act on the surface of the shaped track 1 in a high-frequency reciprocating motion. Through continuous and uniform pressure transmission, the stress accumulated inside the track 1 due to deformation reset and secondary shaping process will be fully released, thereby completely avoiding the risk of the track 1 bending again due to stress release in subsequent use.

[0039] Through the coordinated operation of the above three steps of correction and repositioning, secondary shaping, and stress leveling, the top support mechanism 3 achieves active, full-process repair of the deformed track 1, which not only significantly improves the stability and accuracy of track 1 repositioning, but also fundamentally ensures the structural integrity of track 1 in long-term use.

[0040] Reference Figure 3 The adjustable shaft 32 includes two rotating shafts 321 corresponding to the moving block 31, and the rotating shafts 321 are mounted on the moving block 31. A rotating rod 322 coaxial with the two rotating shafts 321 is installed between them, and the two ends of the rotating rod 322 are installed on the rotating shaft 321 by threaded connection.

[0041] Reference Figure 4 and Figure 5 One end of the rotating shaft 321 near the corresponding moving block 31 passes through the opposite surface of the moving block 31 and is rotatably mounted on the moving block 31 through a bearing. A connecting groove 311 is provided inside the moving block 31. A ratchet 323 is installed at one end of the rotating shaft 321 located in the connecting groove 311. A pawl 324 that cooperates with the ratchet 323 is installed inside the connecting groove 311.

[0042] Fasteners (not shown in the figure) are installed on the rotating rod 322. When the occupants tighten the fasteners, the rotating shaft 321 and the rotating rod 322 remain relatively fixed. Fasteners can preferably be bolts. In the initial position, the adjusting shaft 32 is located inside the storage slot 21. In actual operation, when a car accident occurs in a remote area and the occupants cannot open the car door to save themselves, they can open the sunroof to save themselves. The occupants take out the adjusting shaft 32 from the storage slot 21 and move it horizontally. During the movement of the adjusting shaft 32, the moving block 31 moves synchronously and enters the sliding slot 12. When the moving block 31 is obstructed in the sliding slot 12, the movement of the moving block 31 stops.

[0043] At this point, it indicates that track 1 has deformed in its width direction. The personnel inside the vehicle have not tightened the fasteners, but manually turned the rotating rod 322. During the rotation of the rotating rod 322, the rotating shaft 321 is driven to move to the corresponding side of track 1 through the threaded connection. At this time, the rotating rod 322 is unidirectionally limited by the ratchet 323 and the pawl 324, so that the rotating rod 322 does not rotate during the movement. This avoids the possibility that the friction between the rotating shaft 321 and the rotating rod 322 is too large, causing the rotating rod 322 to drive the rotating shaft 321 to rotate synchronously. During the movement of the rotating shaft 321, it cooperates with the moving block 31 to move the track 1 away from each other, thereby correcting and resetting the track 1 in the width direction.

[0044] Reference Figure 6 When track 1 undergoes deformation in the length direction (i.e., track 1 undergoes bending deformation), the straightening block 333 can straighten and reset track 1. Specifically, the straightening component 33 includes a straightening block 331 installed on the moving block 31. The straightening block 331 has a rectangular groove inside, and an adjusting block 332 is slidably arranged inside the rectangular groove. The end of the adjusting block 332 away from the moving block 31 is provided with a guide slope symmetrically arranged along the height direction of the straightening block 331. The straightening block 331 is symmetrically arranged with straightening blocks 333 along its height direction, and the straightening blocks 333 are slidably arranged through the straightening block 331. The side of the straightening block 333 near the rectangular groove is provided with a lifting block 334 that cooperates with the guide slope.

[0045] It should be noted that when track 1 deforms in the length direction, the degree of deformation varies significantly, and the corresponding responses are also very different: when the degree of deformation is small, the resulting gap size is within a reasonable range, and the correction block 331 can be smoothly embedded in it. In this way, the deformation of track 1 can be effectively corrected and its normal state restored.

[0046] However, if the deformation reaches a certain level, or even becomes extremely severe, the situation becomes extremely difficult. At this point, the severe deformation of track 1 may not only cause serious damage to the moving vehicle, but also directly threaten the lives of the people inside, leading to serious injuries. Furthermore, due to the excessive deformation, the people inside the vehicle are completely unable to complete the track 1 correction work on their own, and professional rescue forces and equipment must be relied upon to handle the situation.

[0047] In specific operation, when the moving block 31 encounters a deformation of the track 1 in the length direction during the movement of the moving block 31, the moving block 31 cannot continue to move due to the obstruction of the deformed part of the track 1. At this time, the correcting block 331 moves into the gap generated by the deformation and drives the adjusting block 332 to move through the existing driving force (cylinder push, etc.). During the movement of the adjusting block 332, the guide inclined plane moves synchronously and drives the lifting block 334 to move away from the adjusting block 332. During the movement of the lifting block 334, the correcting connecting block 333 moves synchronously. Thus, during the movement of the correcting connecting block 333, the deformation in the length direction of the track 1 can be corrected and reset until the track 1 is reset to the initial state.

[0048] Reference Figure 5 and Figure 6 After track 1 is reset, moving block 31 continues to move and covers the previously reset portion of the correction block 333. Specifically, pressing plates 312 are provided through the top and bottom of moving block 31, and pressing plates 312 are slidably arranged along the length of moving block 31. Multiple pressing rollers 313 are evenly arranged along the length of the side of pressing plate 312 away from connecting groove 311, and pressing rollers 313 are rotatably mounted on pressing plate 312 through bearings.

[0049] A bevel gear 314 is installed at one end of the rotating shaft 321 located in the connecting groove 311. A bidirectional screw 315 corresponding to the pressing plate 312 is symmetrically arranged inside the connecting groove 311 along its length. A support plate 316 corresponding to the bidirectional screw 315 is installed inside the connecting groove 311, and the bidirectional screw 315 is rotatably mounted on the support plate 316 through bearings. A linkage plate 317 corresponding to the bidirectional screw 315 is installed on the pressing plate 312, and the corresponding bidirectional screw 315 is connected to the linkage plate 317 through a threaded connection. A bevel gear 318 that meshes with the bevel gear 314 is installed at the end of the bidirectional screw 315 near the rotating shaft 321.

[0050] During actual operation, the operator inside the vehicle must first tighten the relevant fasteners to ensure a stable relative fixed relationship between the rotating shaft 321 and the rotating rod 322. After completing this preparatory step, the operator reverses the rotating rod 322. At this time, under the transmission action of the fasteners, the rotating shaft 321 will rotate synchronously in the opposite direction with the rotating rod 322. As the rotating shaft 321 reverses direction, the ratchet 323 and pawl 324, which originally limited its movement, will be released from their locked state, thus giving the rotating shaft 321 space to rotate freely. During the free rotation of the rotating shaft 321, the bevel gear 318 connected to it will rotate synchronously; and since the bevel gear 318 and the bevel gear 314 are in a meshing state, the bevel gear 314 will drive the bidirectional screw 315 to rotate under the drive of the bevel gear 318. When the bidirectional screw 315 rotates, it drives the linkage plate 317 to reciprocate along the length of the connecting groove 311 through the threaded connection structure. The reciprocating movement of the linkage plate 317 further transmits power through the pressing plate 312, causing the pressing roller 313 to perform reciprocating pressing operations on the track 1 that has completed the correction and reset. Through this series of continuous mechanical actions, the deformed parts of the track 1 can be precisely reshaped, thereby effectively improving the overall flatness and structural stability of the track 1.

[0051] Reference Figure 8 The leveling component 34 includes a rubber strip 341 on the side of the moving block 31 away from the straightening block 331, a leveling block 342 mounted on the rubber strip 341, a reciprocating block 343 slidably mounted through the moving block 31 and connected to the leveling block 342, a rotating connecting rod 344 mounted on the rotating shaft 321, a swing rod 345 mounted on the rotating connecting rod 344 via a hinge, and the end of the swing rod 345 away from the rotating connecting rod 344 mounted on the reciprocating block 343 via a hinge.

[0052] It should be noted that the flattening block 342 is made of rubber and its height is slightly greater than that of the sliding groove 12. In actual operation, after the secondary shaping is completed, the moving block 31 is pushed to move and the flattening block 342 covers the deformed part of the track 1 that was previously shaped by the secondary shaping. Since the height of the flattening block 342 is slightly greater than that of the sliding groove 12, the flattening block 342 applies a squeezing force to the upper and lower side walls of the sliding groove 12. Since the track 1 is an arc-shaped structure, the rubber strip 341 adaptively adjusts the position of the flattening block 342 and the moving block 31 during the movement of the flattening block 342 to avoid rigid pulling between the flattening block 342 and the moving block 31. The rubber strip 341 can be stretched along the length of the track 1.

[0053] During the rotation of the rotating shaft 321, the rotating connecting rod 344 is driven to rotate. During the rotation of the rotating connecting rod 344, the swing rod 345 is driven to swing back and forth. During the swinging back and forth of the swing rod 345, the reciprocating block 343 is driven to move back and forth. During the movement of the reciprocating block 343, the flattening block 342 is driven to move back and forth inside the sliding groove 12. During the reciprocating movement of the flattening block 342, the stress inside the track 1 can be reduced, and the possibility of the deformed part of the track 1 returning to its original position after flattening can be reduced.

[0054] In order to reduce the friction between the leveling block 342 and the inside of the sliding groove 12, ball bearings can be installed in the part of the leveling block 342 that contacts the inner wall of the sliding groove 12. This is a common adaptive modification and is therefore not shown in the figure or described in detail.

[0055] Reference Figure 9 To reduce the use of driving force, the rack plate 340 of the present invention drives the adjusting block 332 to reciprocate through the interaction of the rack plate 346 and the linkage gear 349. Specifically, the adjusting block 332 and the moving block 31 are slidably connected through each other on the corresponding side. The rack plate 346 is installed on the bottom of the reciprocating block 343 through the connecting protrusion. A support frame 347 is installed inside the connecting groove 311. A transmission shaft 348 is installed on the support frame 347 through the bearing. The linkage gear 349 that meshes with the rack plate 346 is installed on the transmission shaft 348. A support protrusion is provided at the bottom of the connecting groove 311. The rack plate 340 that meshes with the linkage gear 349 is slidably arranged on the support protrusion. A vertical frame 3401 is installed on the rack plate 340. A linkage frame 3410 is installed on the vertical frame 3401. The end of the linkage frame 3410 away from the vertical frame 3401 is installed on the adjusting block 332.

[0056] In specific operation, the reciprocating block 343 moves back and forth, driving the rack plate 346 to move. During the movement of the rack plate 346, it meshes with the linkage gear 349, driving the rack plate 340 to move back and forth. During the reciprocating movement of the rack plate 340, it drives the linkage frame 3410 to move back and forth. During the reciprocating movement of the linkage frame 3410, it drives the adjusting block 332 to move back and forth. Thus, the adjusting block 332 can be driven to move back and forth without external driving force.

[0057] It should be noted that in the structural design of this device, the length of the correcting block 331 is set to be less than the length of the moving block 31. This dimensional ratio has important practical significance: when the moving block 31 is adjusted for displacement, its maximum movement distance each time is strictly limited to within the length of the correcting block 331. This design ensures that the moving block 31 and the pressing block always maintain complete coverage of the area corrected by the straightening block 331. Even during the dynamic adjustment of the moving block 31's position, there will be no blind spots due to excessive displacement. As a result, the supporting mechanism 3 can continuously operate on the corrected track 1 area during continuous operation, effectively avoiding work interruptions or omissions. From a structural design perspective, this provides a reliable guarantee for the continuity and stability of the supporting operation.

[0058] Repeat the above steps to correct and reset track 1.

[0059] Example 2: Reference Figure 2 as well as Figure 10 Based on Embodiment 1, the sunroof glass may break due to mechanical force or potential hidden damage to the sunroof glass itself. Therefore, the shielding cloth 113 provided by the present invention can shield the broken glass. Specifically, a winding shaft 111 is rotatably installed in the storage groove 21 near the leveling component 34 via a bearing, and a connecting block 112 is rotatably installed on the adjusting shaft 32 via a bearing. The shielding cloth 113 is installed between the two connecting blocks 112, and the side of the shielding plate away from the connecting block 112 is wound around the winding shaft 111.

[0060] A coiled spring (which is common knowledge and is not shown in the accompanying drawings) is installed on the winding shaft 111. This coiled spring structure can maintain a stable tension on the shielding cloth 113 wrapped around the surface of the winding shaft 111 through its own elastic restoring force when the winding shaft 111 is not subjected to external force. This ensures that the shielding cloth 113 can be tightly wrapped around the winding shaft 111 when not in operation, effectively preventing it from falling off due to loosening and ensuring the stability of the equipment structure. During operation, when the rotating shaft 321 moves to the designated working area, it drives the adjusting shaft 32 to move synchronously. At this time, the connecting block 112 gradually moves away from the winding shaft 111 under the action of the adjusting shaft 32. The shielding cloth 113 originally wrapped around the winding shaft 111 is then gradually pulled open and unfolded. The unfolded shielding cloth 113 forms a protective barrier in the working area. This barrier can accurately cover the area where glass fragments may be generated. In the event of a broken sunroof, it can effectively block the broken glass fragments, preventing them from flying into the vehicle and thus avoiding secondary injuries to the operators inside the vehicle, providing reliable protection for personnel safety during the operation.

[0061] The implementation principle of this invention is as follows: (1): When the track 1 deforms in its width direction, the personnel in the vehicle do not tighten the fasteners, but manually tighten the rotating rod 322. During the rotation of the rotating rod 322, the rotating shaft 321 is driven to move to the corresponding side of the track 1 through the threaded connection. At this time, the rotating rod 322 is limited in one direction by the ratchet 323 and the pawl 324, so that the rotating rod 322 does not rotate during the movement. During the movement of the rotating shaft 321, it cooperates with the moving block 31 to make the track 1 move away from each other, thereby correcting and resetting the track 1 in the width direction.

[0062] (2): During the movement of the moving block 31, when the moving block 31 encounters the deformation of the track 1 in the length direction, the moving block 31 cannot continue to move due to the obstruction of the deformed part of the track 1. At this time, the correcting block 331 moves into the gap generated by the deformation and drives the adjusting block 332 to move through the existing driving force. During the movement of the adjusting block 332, the guide slope moves synchronously and drives the lifting block 334 to move away from the adjusting block 332. During the movement of the lifting block 334, the correcting connecting block 333 moves synchronously. Thus, during the movement of the correcting connecting block 333, the deformation in the length direction of the track 1 can be corrected and reset until the track 1 is reset to the initial state.

[0063] (3): When the bidirectional screw 315 rotates, it drives the linkage plate 317 to reciprocate along the length of the connecting groove 311 through the threaded connection structure. The reciprocating movement of the linkage plate 317 will further transmit power through the pressing plate 312, so that the pressing roller 313 performs reciprocating pressing operation on the track 1 that has been corrected and reset, so as to perform secondary shaping treatment on the track 1.

[0064] (4): During the rotation of the rotating shaft 321, the rotating connecting rod 344 is driven to rotate. During the rotation of the rotating connecting rod 344, the swing rod 345 is driven to swing back and forth. During the swing of the swing rod 345, the reciprocating block 343 is driven to move back and forth. During the movement of the reciprocating block 343, the flattening block 342 is driven to move back and forth inside the sliding groove 12. During the reciprocating movement of the flattening block 342, the stress inside the track 1 can be reduced.
