Description

Technical Field

[0001] This utility model relates to the field of vehicle door technology, specifically an anti-pinch vehicle door. Background Technology

[0002] Anti-pinch doors are a type of automotive safety feature that primarily relies on anti-pinch rubber pads. Their core function is to prevent people or property from being pinched or damaged during the closing process of the door or door body. When an object comes into contact with the anti-pinch rubber pad, the pad will deform due to compression, thereby triggering an internal sensing mechanism that sends a signal to the control system, causing the door to stop closing or automatically open in the opposite direction. For example, an anti-pinch rubber strip described in announcement number CN219281620U includes a strip body. One side of the strip body is a connecting side that mates with a profile, and the other side is a sealing side. A trigger cavity for installing a sensitive edge is provided on the sealing side. The trigger cavity includes a first cavity wall near the connecting side and a second cavity wall away from the connecting side. Both the inner and outer sides of the second cavity wall are provided with curved portions for length compensation. Although the above-mentioned device extends the service life of the rubber strip, in actual use the rubber strip is a single piece, and the model of the rubber strip is selected according to the vehicle model. It does not take into account the use of multiple rubber strips together, resulting in low flexibility in the installation of the device. Utility Model Content

[0003] The purpose of this invention is to provide an anti-pinch car door to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An anti-pinch car door includes a door body hinged to a vehicle body, a first T-shaped sealing gasket embedded in the outer surface of the door body, and a second T-shaped sealing gasket embedded in the outer surface of the vehicle body. The front surface of the first T-shaped sealing gasket is embedded with a plurality of anti-pinch rubber strip mechanisms. The anti-pinch rubber strip mechanism includes a rubber seat and a trigger strip. The rubber seat is embedded and fixedly connected to the inside of the first T-shaped sealing gasket, and the trigger strip is embedded and fixedly connected to the inside of the rubber seat. Hollow studs are fixedly connected to both ends of the trigger bar, and wires connecting adjacent trigger bars are placed inside the hollow studs.

[0005] Furthermore, the outer surface of the door body is provided with a first T-shaped groove, and the first T-shaped sealing gasket matches the first T-shaped groove.

[0006] Furthermore, the outer surface of the vehicle body is provided with a second T-shaped groove, and the second T-shaped sealing gasket and the second T-shaped groove are matched.

[0007] Furthermore, the front surface of the first T-shaped sealing gasket has an inner cavity, the rubber seat is embedded in the inner cavity, and the front surface of the first T-shaped sealing gasket is integrally connected with an arc-shaped connecting area.

[0008] Furthermore, the anti-pinch rubber strip mechanism also includes a first limiting groove, a second limiting groove, and a squeezing part. The first limiting groove is opened on the front surface of the rubber seat, and there are two first limiting grooves. The second limiting groove is opened on the side surface of the first limiting groove, and there are four second limiting grooves. The squeezing part is integrally connected to the front surface of the rubber seat.

[0009] Furthermore, the trigger bar is embedded and connected inside the second limiting groove.

[0010] Furthermore, the hollow stud is fixedly connected to an extrusion plate at its end, the extrusion plate being able to deform and clamp the wire, and a threaded cylinder is threadedly connected to the outer surface of the hollow stud.

[0011] Compared with the prior art, the beneficial effects of this utility model are: When the electric door is closing, if there is a foreign object, the anti-pinch strip mechanism deforms, causing the adjacent colored trigger strips to contact. This transmits an electrical signal to the controller built into the door via a wire, causing the door to immediately stop closing and move in the opposite direction, thus preventing pinching injuries. When used in conjunction with the first T-shaped sealing gasket and the second T-shaped sealing gasket, it can provide a good seal, preventing dust and moisture from entering, while also effectively insulating sound and improving environmental comfort. The rotating threaded cylinder causes the conical extrusion plates to deform under pressure. After deformation, they can clamp the wires, enabling the connection and conduction between multiple anti-pinch rubber strip mechanisms. This improves the flexibility of device installation. Integrating the anti-pinch rubber strip mechanism with the first T-shaped sealing gasket reduces the space occupied by components, making the overall structure more compact. This design is particularly suitable for space-constrained occasions, such as car doors and subway platform screen doors. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 In this embodiment of the utility model, an anti-pinch car door includes a door body 1 hinged to a car body 2, a first T-shaped sealing gasket 3 embedded in the outer surface of the door body 1, and a second T-shaped sealing gasket 4 embedded in the outer surface of the car body 2. Several anti-pinch rubber strip mechanisms 5 are embedded and connected to the front surface of the first T-shaped sealing gasket 3. The anti-pinch rubber strip mechanism 5 includes a rubber seat 501 and a trigger strip 505. The rubber seat 501 is embedded and fixedly connected to the inside of the first T-shaped sealing gasket 3, and the trigger strip 505 is embedded and fixedly connected to the inside of the rubber seat 501. Hollow studs 6 are fixedly connected to both ends of the trigger bar 505, and wires 7 connecting adjacent trigger bars 505 are placed inside the hollow studs 6.

[0016] Specifically, during use, the door body 1 and the vehicle body 2 are sealed by the first T-shaped sealing gasket 3 and the second T-shaped sealing gasket 4, which can effectively reduce wind noise. When the electric door body 1 closes, if there is a foreign object, the anti-pinch strip mechanism 5 deforms, causing the adjacent colored trigger strip 505 to contact. This transmits an electrical signal to the controller built into the door through the wire 7, causing the door to immediately stop closing and move in the opposite direction, thus avoiding pinching. When used in conjunction with the first T-shaped sealing gasket 3 and the second T-shaped sealing gasket 4, it can play a good sealing role, preventing dust and moisture from entering, while also effectively insulating sound and improving environmental comfort.

[0017] Example 1 like Figure 1-5As shown, a first T-shaped groove 101 is provided on the outer surface of the door body 1, and a first T-shaped sealing gasket 3 is matched with the first T-shaped groove 101. A second T-shaped groove 201 is provided on the outer surface of the vehicle body 2, and a second T-shaped sealing gasket 4 is matched with the second T-shaped groove 201.

[0018] In this embodiment, the T-slot design allows for easy disassembly and reassembly of the first T-shaped sealing gasket 3, the second T-shaped sealing gasket 4, and the anti-pinch rubber strip mechanism 5 without damaging the original structure. This design greatly reduces the difficulty and cost of maintenance and replacement. The T-slot has a uniform standard size, which facilitates the interchangeability of parts and reduces inventory costs.

[0019] like Figure 1-5 As shown, the front surface of the first T-shaped sealing gasket 3 has an inner cavity 301, and the rubber seat 501 is embedded in the inner cavity 301. The front surface of the first T-shaped sealing gasket 3 is integrally connected with an arc-shaped connecting area 302.

[0020] In this embodiment, when subjected to pressure from a foreign object, the arc-shaped connecting area 302 deforms and squeezes the rubber seat 501, causing the adjacent trigger strips 505 to contact, thereby achieving the purpose of connecting the circuit of the anti-pinch rubber strip mechanism 5. Example 2 Based on Embodiment 1, in order to remedy the problem that adjacent anti-pinch rubber strip mechanisms 5 cannot be connected together in Embodiment 1.

[0021] like Figure 1-5 As shown, the anti-pinch rubber strip mechanism 5 also includes a first limiting groove 502, a second limiting groove 503, and a squeezing part 504. The first limiting groove 502 is formed on the front surface of the rubber seat 501, and there are two first limiting grooves 502. The second limiting groove 503 is formed on the side surface of the first limiting groove 502, and there are four second limiting grooves 503. The squeezing part 504 is integrally connected to the front surface of the rubber seat 501, and the trigger strip 505 is embedded in the interior of the second limiting groove 503.

[0022] In this embodiment, there are two sets of trigger strips 505. When the extrusion part 504 is deformed by force, the trigger strips 505 come into contact with each other to realize the conduction of the circuit. Similarly, this embedded connection method is the same as the connection method between the rubber seat 501 and the first T-shaped sealing gasket 3, the first T-shaped sealing gasket 3 and the door body 1, and the second T-shaped sealing gasket 4 and the vehicle body 2. Adhesive needs to be applied during installation.

[0023] like Figure 1-5 As shown, a compression plate 601 is fixedly connected to the end of the hollow stud 6. The compression plate 601 can deform to clamp the wire 7. A threaded cylinder 602 is threadedly connected to the outer surface of the hollow stud 6.

[0024] In this embodiment, the rotating threaded cylinder 602 causes the conical extrusion plates 601 to deform under the pressure of the threaded cylinder 602. After deformation, they can clamp the wire 7, and the wire 7 enables the connection and conduction between multiple anti-pinch rubber strip mechanisms 5, improving the flexibility of device installation. Integrating the anti-pinch rubber strip mechanism 5 with the first T-shaped sealing gasket 3 can reduce the space occupied by the components and make the overall structure more compact. This design is particularly suitable for occasions with limited space, such as car doors and subway platform screen doors.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
