An inward-opening buckle Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology. Specifically, this utility model relates to an inward-opening latch. Background Technology

[0002] As the automotive industry continues to evolve, consumers are placing increasingly stringent demands on the safety, comfort, and convenience of vehicles. As a core component of the car door and window lock system, the performance of the inward-opening latch directly impacts user experience and driving safety.

[0003] Currently, most inward-opening handles on the market have an inward-opening base embedded in the door panel, without an inward-opening structure where the handle detaches from the door panel. This can easily lead to situations where inward-opening handles cannot be installed on flat door panels.

[0004] Chinese Patent (Publication No.: 211776653U) discloses a pull-tie inward-opening latch and a vehicle door and vehicle including the inward-opening latch. The pull-tie inward-opening latch includes: a latch base with openings on both sides; a pin fixed to the latch base; a cable mounting structure rotatably mounted on the pin, one end of which abuts against the unlocking device of the vehicle door; and a pull-tie handle, which is a flexible strip with both ends passing through the openings of the latch base. One end of each end is fixed to the latch base, and the other end is fixedly connected to the other end of the cable mounting structure. This allows the cable mounting structure to rotate around the pin when the pull-tie handle is pulled by an external force, thereby triggering the unlocking device. However, with this pull-tie inward-opening latch and the vehicle door and vehicle including it, the inward-opening latch is not easily installed on a flat door panel. Summary of the Invention

[0005] This utility model is designed to solve the above-mentioned problems and aims to provide an inward-opening handguard that can be installed on a flat door panel. To achieve the above objective, the technical solution adopted by this utility model is as follows: an inward-opening handle, including a door lock tongue and a base, the base being connected to the door, and a transmission unlocking structure being provided on the base, the transmission unlocking structure being connected to the door lock tongue.

[0006] The transmission unlocking structure includes a handle and a first connecting shaft. The handle is connected to the base via the first connecting shaft. A rocker arm is connected to the handle, and a pull cable is connected to the rocker arm. The pull cable is connected to the door lock tongue.

[0007] The base is provided with a connecting structure, which is connected to the car door. The connecting structure includes a first bolt groove and a first retaining plate. The first bolt groove and the first retaining plate are located at the same end of the base. The first retaining plate is provided with a first retaining groove, which is connected to the car door. A bolt is provided in the first bolt groove to connect with the car door.

[0008] A torsion spring is sleeved on the first connecting shaft, and a first connecting plate is provided on the base. A first groove is opened on the first connecting plate, one end of the torsion spring is located in the first groove, and the other end of the torsion spring abuts against the handle.

[0009] The handle includes an upper cover and a lower cover. The upper cover has a second slot, and the lower cover has a second plate that cooperates with the second slot. The second plate is located in the second slot.

[0010] The rocker arm includes a second connecting plate, on which a wire groove is formed, and the pull wire is located in the wire groove.

[0011] The base is equipped with a shock-absorbing pad, one end of which is connected to the handle.

[0012] The handle is provided with a pressing groove.

[0013] A reinforcing plate is connected to the base, and the reinforcing plate is connected to the first bolt groove and the first clamping plate.

[0014] The technical advantages of this invention are as follows: When the user operates the handle, the handle rotates around the first connecting shaft. The rotation of the handle drives the connected rocker arm to move, which in turn pulls the cable. The pulling action of the cable causes the door latch to move accordingly, completing the door unlocking operation. The torsion spring can store energy through elastic deformation when the handle rotates, and after the external force on the handle disappears, it uses its elastic force to push the handle back to its original position. The torsion spring provides the restoring force to the handle. When the user completes the unlocking action by operating the handle, the torsion spring releases the stored elastic potential energy, causing the handle to automatically return to its initial position for the next use.

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0022] As shown in Figures 1-4, an inward-opening latch includes a door latch and a base 1 connected to the door. A transmission unlocking structure 2 is mounted on the base 1 and connected to the door latch. One end of the base 1 is connected to and fixed to the door. The transmission unlocking structure 2 can unlock the latch, thereby controlling the opening of the door.

[0023] The transmission unlocking structure 2 includes a handle 21 and a first connecting shaft 201. The handle 21 is connected to the base 1 via the first connecting shaft 201. A rocker arm 22 is connected to the handle 21, and a pull cable is connected to the rocker arm 22. The pull cable is connected to the door latch. The base 1 is a base plate with fixed plates connected to both ends. The first connecting shaft 201 is mounted on the fixed plate. The handle 21 is connected to the base 1 via the first connecting shaft 201, allowing the handle 21 to rotate around the first connecting shaft 201. The rocker arm 22 connected to the handle 21 can effectively transmit power. A pull cable is connected to the rocker arm 22, and the other end of the pull cable is connected to the door latch. Through the flexible connection of the pull cable, the movement of the rocker arm 22 is transmitted to the door latch, realizing the control of the door latch. When the user operates the handle 21, the handle 21 rotates around the first connecting shaft 201. The rotation of the handle 21 drives the rocker arm 22 connected to it to move. The rocker arm 22 then pulls the pull cable. The pulling action of the pull cable causes the door latch to move accordingly, completing the door unlocking operation.

[0024] A connecting structure 3 is provided on the base 1, which connects to the car door. The connecting structure 3 includes a first bolt groove 301 and a first retaining plate 302, which are located at the same end of the base 1.

[0028] A shock-absorbing pad 5 is provided on the base 1, and one end of the shock-absorbing pad 5 is connected to the handle 21. During the operation of the handle 21, the shock-absorbing pad 5 plays a role in buffering and shock absorption, reducing noise and wear caused by collision or friction between the handle 21 and the base 1, and improving the comfort and lifespan of the inward-opening handle.

[0029] The handle 21 is provided with a pressing groove 6. The size of the pressing groove 6 is 1.3 times the size of a normal person's thumb, making it convenient for the user to press the handle 21.

[0030] A reinforcing plate 7 is connected to the base 1, and the reinforcing plate 7 is connected to the first bolt groove 301 and the first retaining plate 302. This enhances the strength of the connection between the base 1 and the door, improves the overall stability of the inward-opening handle structure, and reduces the risk of damage or loosening of the connection due to frequent operation or large external forces. The reinforcing plate 7, connected to the first bolt groove 301 and the first retaining plate 302, works together at the connection between the base 1 and the door, improving the load-bearing capacity and deformation resistance of this part.

[0031] The role and effect of the embodiments

[0032] When the user operates handle 21, handle 21 rotates around the first connecting shaft 201. The rotation of handle 21 drives the connected rocker arm 22 to move, which in turn pulls the cable. The pulling action of the cable causes the door latch to move accordingly, completing the door unlocking operation. The torsion spring 8 can store energy through elastic deformation when handle 21 rotates, and after the external force on handle 21 disappears, it uses its elastic force to push handle 21 back to its original position. The torsion spring 8 provides the restoring force for handle 21. After the user operates handle 21 to complete the unlocking action, the torsion spring 8 releases the stored elastic potential energy, causing handle 21 to automatically return to its initial position for the next use.
