Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a quick-replaceable automotive anti-pinch strip assembly. Background Technology

[0002] An anti-pinch strip for automobiles is a device installed on the doors and windows of a car that can directly detect whether there is an obstruction when the door or window is closed. Its rubber body contains an anti-pinch detection structure including positive and negative wires. When the car door or window catches an object and encounters an obstruction during closing, the positive and negative wires are compressed and make contact, thereby changing the conductivity of the circuit and triggering the anti-pinch protection function.

[0003] Existing anti-pinch strips are typically installed using screws, clips, snap-fit ​​connections, or adhesive to the frame of car door windows. When these strips age, wear, or their detection structure is damaged, replacement is cumbersome and usually requires professional repair personnel. For ordinary car owners, self-replacement is difficult and time-consuming, increasing maintenance costs and failing to meet the need for quick replacement. Therefore, improving the installation method of existing anti-pinch strips to overcome these problems is a problem urgently needing to be solved by those skilled in the art. Summary of the Invention

[0004] One of the objectives of this application is to provide a quick-replaceable automotive anti-pinch strip assembly, which enables convenient disassembly and replacement of the anti-pinch strip, reduces the difficulty and time required for replacement, and meets the technical solution for ordinary car owners to replace it themselves.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a quick-replaceable automotive anti-pinch strip assembly, comprising an anti-pinch strip body, multiple fasteners, a winding device, and a rope. Multiple positioning elements are spaced apart on the back side of the anti-pinch strip body. The fasteners are movably disposed within the vehicle body. The winding device is installed within the vehicle body. The rope is adapted to sequentially connect multiple fasteners in series, and the end of the rope is connected to the winding device. During installation, the anti-pinch strip body is adapted to first be inserted into the vehicle body via the positioning elements. Subsequently, the winding device is adapted to use the rope to pull the fasteners to move synchronously until they engage and lock with the corresponding positioning elements.

[0006] Preferably, the positioning member is provided with a positioning hole, and the fastener is slidably disposed in the vehicle body through an elastic member; during installation, the fastener is adapted to be inserted and engaged with the positioning hole under the action of elastic force and traction force.

[0007] Preferably, the fastener is perpendicular to the positioning member, and the side of the fastener has a wedge-shaped portion; during installation, the wedge-shaped portion engages with the positioning hole in a wedge-shaped compression fit, thereby driving the positioning member to move in a direction close to the fastener.

[0008] Preferably, the position where the positioning component is inserted into the vehicle body is a non-circular structure, thereby achieving rotational limitation of the positioning component in the circumferential direction.

[0009] Preferably, a damping part is provided at the position where the positioning member is inserted into the vehicle body; the damping part is adapted to pre-position the inserted positioning member so that the fastener corresponds to the positioning hole.

[0010] Preferably, the winding device includes a transmission assembly and a pair of rollers. The rollers are rotatably mounted in the vehicle body via a bracket. The ends of the two rollers are engaged by the transmission assembly. The two ends of the rope are respectively connected to the corresponding rollers. During assembly and disassembly, one of the rollers is driven to rotate, and the other roller is adapted to rotate synchronously under the action of the transmission assembly, thereby realizing the synchronous winding and unwinding of the two ends of the rope.

[0011] Preferably, one of the rollers is provided with a drive unit at one end, the drive unit being adapted to cooperate with an external disassembly or assembly tool to drive the roller to rotate.

[0012] Preferably, one of the rollers is provided with a drive unit at one end, the drive unit being adapted to cooperate with an external disassembly or assembly tool to drive the roller to rotate.

[0013] Preferably, the limiting component includes a sleeve and a limiting member. The sleeve is installed on the bracket and sleeved on the outside of the driving part. The inner side of the sleeve is provided with a plurality of slots at equal intervals along the circumferential direction. The limiting member is elastically slidably disposed on the axial inner side of the driving part. The limiting member has a locking block on its outside. The locking block is adapted to cooperate with the slots under the action of elastic force, thereby realizing the locking of the roller.

[0014] Preferably, the end of the driving part has a driving groove that cooperates with the disassembly and assembly tool, and one end of the limiting member extends into the driving groove; during disassembly and assembly, the disassembly and assembly tool is adapted to insert into the driving groove and squeeze and push the limiting member so that the locking block disengages from the locking groove.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: (1) By providing a winding device, rope and fasteners inside the car door, the present invention allows for easy disassembly and assembly. In this process, the anti-pinch strip body is pre-inserted into the corresponding position of the car body through the positioning component, and then the rope is wound up by the winding device. All fasteners can be moved synchronously at one time, thereby completing the locking and fixing of all positioning components to the car body. When disassembling, only the rope needs to be unwound to release the locking of all fasteners to the positioning component at one time. The operation steps are simple and do not require disassembly and assembly of each fastener. This can greatly reduce the time required for disassembly and replacement of the anti-pinch strip, and does not require professional maintenance personnel, thus effectively reducing the cost of anti-pinch strip replacement and maintenance.

[0016] (2) By setting a limit component on the roller body, the present invention can lock the roller body after the rope is wound up, so as to prevent the roller body from rotating unexpectedly and improve the reliability of the structure. When disassembly and assembly are required, the limit component can be pushed to release the lock by inserting the disassembly and assembly tool into the drive groove, and then the roller body can be driven to rotate. The operation is smooth and continuous, without adding any additional disassembly and assembly steps, and can maintain the convenience of quick disassembly and assembly. Attached Figure Description

[0030] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] Further description of existing technologies: With the development of new energy vehicles, the demand for automotive intelligence is also constantly evolving. A common issue is that closing a car door can cause passengers to get trapped. Many anti-pinch designs exist for car doors, with anti-pinch strips being widely used due to their simple structure and ease of installation. Anti-pinch strips are also commonly found on tailgates, windows, sunroofs, and hoods. While anti-pinch strips also function as a seal, they contain conductive components, resulting in a shorter lifespan compared to ordinary sealing strips. Prolonged pressure or exposure to the environment can easily lead to aging, cracking, and detection failure, requiring timely replacement.

[0034] Further description of the defects of the existing technology: The existing anti-pinch strips are mostly installed in the following ways: (1) Screw installation, which is the most traditional method. It is cumbersome to operate, and the screws removed are easy to lose. In addition, stripped screws will damage the original mounting holes of the door 1. (2) Clip-on connection (such as Figure 1 As shown in the above figure), it is generally necessary to pry it out with a pry bar during disassembly. Disassembly and assembly are time-consuming and laborious, and it is also easy to damage the original mounting holes of the door 1. (3) Adhesive fixing (such as Figure 1 As shown in the middle figure), the adhesive layer is prone to aging and delamination after long-term exposure, and the adhesive residue is difficult to clean when replacing. (4) Snap-fit ​​(such as Figure 1 As shown in the image below, the anti-pinch strip is engaged through its own mounting groove and the anti-detachment structure inside the groove. However, after prolonged use, the anti-detachment structure is prone to aging and loosening, and disassembly and reassembly still require prying, which can easily scratch the mounting area. Therefore, regardless of the type of existing anti-pinch strip mounting structure, replacement is inconvenient, and ordinary car owners cannot easily disassemble and reassemble it themselves.

[0035] Therefore, the inventors of this application have developed a quick-replaceable automotive anti-pinch strip assembly, one embodiment of which is, for example... Figures 1 to 12 As shown, it includes an anti-pinch strip body 2, multiple fasteners 7, a winding device 5, and a rope 8. Multiple positioning elements 6 are spaced apart on the back side (i.e., the installation side) of the anti-pinch strip body 2. The fasteners 7 are movably installed inside the door 1. The winding device 5 is installed inside the door 1. The rope 8 connects the multiple fasteners 7 in series. The end of the rope 8 is connected to the winding device 5.

[0036] Understandably, when installing the anti-pinch strip body 2, the anti-pinch strip body 2 is first pre-installed by aligning each positioning piece 6 with the preset mounting holes on the door 1. After all positioning pieces 6 are in place, the winding device 5 can be operated. The winding device 5 will drive the rope 8 to complete the winding action. During the winding process, the rope 8 will simultaneously pull all fasteners 7 to move synchronously. Figure 6 As shown in the diagram below, the entire anti-pinch strip body 2 can be fixed and installed in one go until each fastener 7 is engaged and locked with the corresponding positioning piece 6. Of course, when disassembling the anti-pinch strip body 2, simply operate the winding device 5 to unwind the rope 8, and use the rope 8 to pull the fasteners 7 in the opposite direction to release the engagement between each fastener 7 and the corresponding positioning piece 6. Then, the anti-pinch strip body 2 can be directly removed from the car door 1. The entire disassembly and assembly process can be completed by operating the winding device 5. There is no need to disassemble and assemble each fastener 7 individually. Ordinary car owners can also complete the replacement themselves. The operation is simple and the disassembly and assembly speed is fast.

[0037] It should be noted that the anti-pinch strip in this application is not limited to use at door 1, and can also be adapted and installed at other anti-pinch locations on the vehicle body as needed. For ease of understanding, this application only describes the installation at door 1 as an example. In addition, in order to allow the rope 8 to slide smoothly, a channel and guide wheel can be pre-set at the corresponding position inside door 1 for the rope 8 to pass through, to avoid the rope 8 from getting stuck in the internal structure of the vehicle body, and to ensure the stability of the winding and unwinding process.

[0038] As a further description of the above embodiments: as Figures 3 to 5 As shown, a positioning hole 601 is provided on the positioning member 6, and the fastener 7 can be slidably installed inside the door 1 through an elastic element (such as a spring). It can be understood that during installation, after the positioning member 6 is inserted into place, the fastener 7, under the combined action of the traction force of the rope 8 and the elastic force of its own elastic element, will insert into the positioning hole 601 of the corresponding positioning member 6 to complete the engagement. The function of the spring is to ensure that the fastener 7 always maintains a tendency to move towards the positioning hole 601, ensuring the stability of the engagement and preventing loosening.

[0039] Based on the aforementioned modifications, the winding device 5 can be omitted due to the spring's action. During installation, the spring force allows the fasteners 7 to automatically insert into the positioning holes 601 for engagement. The rope 8 then functions to overcome the spring force during disassembly, pulling all the fasteners 7 back synchronously, thus releasing the locking of all positioning components 6 at once, achieving the same rapid disassembly effect. In short, during disassembly, pulling the rope releases the anti-pinch strip body 2, while during installation, the spring force automatically locks it in place, meeting the requirements for quick assembly and disassembly.

[0040] In one embodiment of this application, such as Figure 5 As shown, the fastener 7, which is slidably installed inside the door 1, and the positioning member 6, which is plugged in, are vertically distributed. The fastener 7 has a wedge-shaped portion 701 on its side. It can be understood that when the fastener 7 moves toward the positioning hole 601 under the traction of the rope 8, the wedge-shaped portion 701 will first contact the edge of the positioning hole 601. As the fastener 7 continues to move, the wedge-shaped portion 701 will generate a wedge-shaped pressing force on the positioning hole 601. This pressing force will drive the entire positioning member 6 to move in the direction close to the fastener 7, thereby causing the anti-pinch strip body 2 to press against the mounting surface of the door 1, reducing the assembly gap between the anti-pinch strip body 2 and the mounting surface of the door 1. This can improve the structural stability after installation and enhance the sealing effect of the anti-pinch strip.

[0041] Further optimization, such as Figure 5As shown, the position where the positioning part 6 is inserted into the door 1 is a non-circular structure (e.g., a D-shaped structure). This allows the positioning part 6 to be rotated and limited in the circumferential direction after it is inserted, preventing it from deflecting during the compression and locking process. This ensures that the positioning hole 601 is always aligned with the fastener 7, improving the reliability of the installation.

[0042] Further optimization involves providing a damping part 9 at the insertion point of the positioning component 6 and the door 1. The friction between the damping part 9 and the mounting hole of the door 1 pre-positions the inserted positioning component 6, preventing it from falling off under gravity during initial installation. This facilitates subsequent synchronous locking operations and ensures that the fastener 7 aligns perfectly with the positioning hole 601 after pre-installation. The damping part 9 can be made of rubber or plastic, generating sufficient damping friction through an interference fit to achieve pre-positioning without hindering manual disassembly and assembly. For example, a "click" sound can be heard during insertion, indicating to the operator that the positioning component 6 has been inserted correctly, allowing the operator to easily assess the installation status.

[0043] In one embodiment of this application, such as Figure 8 As shown, the winding device 5 includes a transmission assembly 502 and a pair of rollers 501. The rollers 501 are rotatably mounted inside the door 1 via a bracket 10, and the ends of the two rollers 501 are engaged by the transmission assembly 502. The two ends of the rope 8 are respectively connected to the corresponding rollers 501. It can be understood that when disassembling or assembling the anti-pinch strip body 2, only one roller 501 needs to be rotated, and the other roller 501 can rotate synchronously under the action of the transmission assembly 502, thereby achieving synchronous winding and unwinding of the two ends of the rope 8, thus ensuring that the rope 8 can pull the fastener 7 to move stably.

[0044] It should be noted that the transmission assembly 502 can have various structural forms, such as belt drive, gear meshing drive, or chain drive, as long as it can ensure that the two rollers 501 rotate synchronously. In this embodiment, gear meshing drive is preferred, with two meshing gears installed at the same end of the two rollers 501 respectively. The structure is compact, the transmission is stable, and it can be adapted to the compact installation space inside the car door 1.

[0045] Further preferably, a drive unit 3 can be provided at the end of one of the rollers 501, and the drive unit 3 can cooperate with external disassembly and assembly tools. For example, the disassembly and assembly tool can be a commonly used hex wrench 11, and the drive unit 3 is provided with a corresponding (hex) drive groove 301, that is, no special disassembly and assembly tools are required, further reducing the threshold for self-replacement. Of course, the disassembly and assembly tools can also be common tools such as flathead screwdrivers and Phillips screwdrivers, and only the shape of the drive groove 301 needs to be adjusted accordingly, which has strong adaptability and is convenient for ordinary car owners to operate.

[0046] Based on the above embodiments, the following problems may exist during use: after the roller body 501 rotates, it cannot be guaranteed that the roller body 501 can maintain the adjusted locked state, which increases the inconvenience of disassembly; that is, one hand needs to hold the Allen wrench 11 to prevent it from rotating, while the other hand is used to disassemble the anti-pinch strip body 2, which is not convenient. In addition, although the limit of the anti-pinch strip body 2 can be kept locked by the action of the elastic element on the fastener 7, after long-term use, the elasticity of the elastic element may decrease, which may cause the roller body 501 to rotate unexpectedly, thereby causing the rope 8 to loosen and affecting the stability of the anti-pinch strip body 2 installation.

[0047] Therefore, in order to solve the above-mentioned technical problems, in one embodiment of this application, such as Figure 9 As shown, a limiting component 4 can be provided between the drive unit 3 and the bracket 10. The limiting component 4 can lock the corresponding roller 501 to prevent the roller 501 from rotating unexpectedly after adjustment. Specifically, the limiting component 4 includes a sleeve 401 and a limiting member 402. The sleeve 401 is fixedly installed on the bracket 10 and sleeved on the outside of the drive unit 3. Multiple slots 4011 are provided at intervals along the circumferential direction on the inner side of the sleeve 401. The limiting member 402 is slidably disposed on the inner side of the drive unit 3 and is slidably disposed along the axial direction of the drive unit 3. A locking block 4021 is provided on the outside of the limiting member 402.

[0048] Under normal conditions, the limiting member 402 can keep the locking block 4021 locked into the slot 4011 by the internally pre-pressed elastic element. At this time, the circumferential direction of the drive unit 3 and the roller 501 will be limited and locked, preventing rotation and maintaining the current winding or unwinding state to avoid accidental rotation and ensure structural stability. When it is necessary to rotate the roller 501 for disassembly or assembly, simply press the limiting member 402 inward to drive the locking block 4021 out of the slot 4011, releasing the rotation restriction on the roller 501. At this time, the roller 501 can be rotated to complete the winding and unwinding adjustment of the rope 8. After the adjustment is completed, release the limiting member 402, and the locking block 4021 will re-lock into the corresponding slot 4011 under the action of the elastic element, completing the locking again. The operation is simple.

[0049] Specifically, such as Figure 2 and Figure 8 As shown, one end of the limiting member 402 extends into the (internal hex) drive groove 301. When operation is required, inserting the internal hex wrench 11 will push the limiting member 402 inward to release the rotation limit. No additional operation is required on the limiting member 402. Inserting the wrench will unlock it, and pulling out the wrench will automatically return it to the locked position. The entire operation process is smooth and continuous, without adding any extra operation steps, making it very convenient to use.

[0050] It should be noted that the number of slots 4011 is related to the positioning accuracy. More slots 4011 allow the locking block 4021 to accommodate more different rotation positions when it engages, improving the accuracy of position adjustment after winding. Therefore, the number of slots 4011 can be adjusted according to the requirements of installation accuracy, and this application does not impose specific limitations here. Of course, during the actual adjustment, there may be a situation where the locking block 4021 is misaligned with the two slots 4011 and cannot be fully engaged. In this case, it is only necessary to slightly rotate the roller 501 so that the locking block 4021 can be aligned and engaged with the nearest slot 4011. The operation is simple; of course, this will not affect the locking state of the overall structure.

[0051] The working principle of this invention is as follows: (1) First, insert each positioning piece 6 on the anti-pinch strip body 2 into the preset mounting hole of the door 1 in sequence until each positioning piece 6 is pre-positioned under the action of the damping part 9. At this time, all positioning pieces 6 will not fall off. With the design of the non-circular structure of the positioning piece 6, it can be ensured that the positioning hole 601 is aligned with the fastener 7 at the corresponding position after insertion, and the pre-assembly before installation is completed.

[0052] (2) Insert the Allen wrench 11 into the drive slot 301. During insertion, push the limiting member 402 inward to disengage the locking block 4021 from the slot 4011, thus releasing the rotation lock of the roller body 501. Then rotate the Allen wrench 11 to drive the two roller bodies 501 to rotate synchronously, as shown in the image. Figure 6 As shown by the arrow in the lower middle diagram, one end of the rope 8 is wound up while the other end is unwound simultaneously. The rope 8 drives all the fasteners 7 to move synchronously toward the corresponding positioning holes 601. During this process, the wedge-shaped part 701 of the fastener 7 is gradually inserted into the positioning hole 601. Through wedge compression, the entire anti-pinch strip body 2 is pressed against the mounting surface of the door 1 to eliminate assembly gaps. After all the fasteners 7 are in place, the rotating roller 501 is stopped, the Allen wrench 11 is pulled out, the limiting part 402 returns to its original position under the action of the internal elastic part, and the locking block 4021 re-engages into the corresponding slot 4011 to complete the locking. The installation and fixing of the entire anti-pinch strip body 2 can be completed in one go.

[0053] (3) When it is necessary to disassemble and replace the anti-pinch strip body 2, insert the Allen wrench 11 again to unlock the limit of the roller body 501, rotate the roller body 501 in the opposite direction, and the rope 8 pulls all the fasteners 7 out of the positioning hole 601 in the opposite direction to release the locking state of each positioning part 6. Then pull out the Allen wrench 11 and limit the roller body 501 again through the card block 4021 and the card slot 4011. Finally, the anti-pinch strip body 2 can be removed directly from the car door 1 to complete the disassembly. The entire disassembly and assembly process does not require disassembling and assembling each fastener 7 one by one. The operation steps are simple and ordinary car owners can complete the replacement by themselves without the help of professional tools. The replacement is more convenient and worry-free.

[0054] In summary, when removing or installing the anti-pinch strip, a simple operation involves using a common Allen wrench 11 to rotate clockwise or counterclockwise to drive the winding device 5 to wind or unwind the rope 8. This simultaneously locks or unlocks all fasteners 7, requiring no specialized tools and causing no additional prying damage to the door 1. The replacement process is simple and convenient. In other words, when car owners want to replace the anti-pinch strip, they don't need to take their vehicle to a repair shop. They can purchase a suitable anti-pinch strip online or at a physical store and replace it themselves. This saves on repair and installation labor costs and allows for greater flexibility in choosing different specifications or styles of anti-pinch strips according to their needs, resulting in a better user experience.
