Description

Technical Field

[0001] This utility model relates to a car door handle assembly. Background Technology

[0002] A door handle assembly is a complete set of components installed on a car door, which includes all the mechanical parts required to open and close the door.

[0003] The door handle assembly mainly includes the handle, locking mechanism, transmission device, limiter, and other auxiliary components. Usually, a pad is installed on the rear side of the door handle assembly to reduce noise and vibration when opening and closing the door. Some pads also play a certain sealing role to reduce the possibility of external moisture and dust falling into the door handle housing.

[0004] The most common way to connect the gasket to the door handle housing is by bolting. This requires machining screw holes in the housing to connect the gasket and the bolt. Disassembly and assembly require tools such as a screwdriver to rotate the bolt head and remove it from the housing. For some applications, manufacturers may choose to use industrial-grade adhesives to directly bond the gasket to the door handle housing. This method provides a very tight bond but makes gasket removal and replacement inconvenient.

[0005] Therefore, how to achieve removable gaskets while efficiently determining the relative positions of the gaskets and cover plates has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a door handle assembly that enables the cover plate and the gasket to be stably connected together through the alignment and cooperation of the limiting slot and the limiting block, as well as the limiting groove and the limiting protrusion.

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a cover plate, a lock cylinder, a handle located on the front side of the cover plate, and a pad located on the rear side of the cover plate. The pad is detachably connected to the cover plate. The lock cylinder is rotatably mounted on the cover plate and a swing arm is fixedly mounted on the rear side of the cover plate. A limiting protrusion is provided on the left side of the cover plate facing rearward. A limiting slot is provided on the pad corresponding to the limiting protrusion. Limiting blocks that abut against the limiting protrusion are provided on both the upper and lower sides of the pad at the limiting slot. A first limiting plate, a second limiting plate, and a limiting groove located between the first and second limiting plates are provided on the right side of the cover plate. A limiting protrusion with the limiting groove is provided on the pad facing forward. One end of the limiting protrusion abuts against the first limiting plate, and the other end abuts against the second limiting plate.

[0008] The present invention is further configured such that: the gasket includes a plurality of mating plates, and the cover plate is provided with a positioning post protruding rearward for each mating plate, and each mating plate is provided with a positioning groove for the corresponding positioning post to be inserted.

[0009] The present invention is further configured such that: the gasket also includes a connecting plate, the connecting plate includes fitting sleeves located on the left and right sides, each fitting sleeve is provided with an installation groove, and the cover plate is provided with an installation protrusion corresponding to each installation groove.

[0010] The present invention is further configured such that: the cover plate is provided with an upper positioning block protruding between each mounting protrusion; both the connecting plate and the upper positioning block are made of a material that is prone to deformation; the connecting plate is provided with an upper positioning slot corresponding to the upper positioning block; the upper positioning block includes an insertion section and a limiting section; the insertion section is located in the upper positioning slot; and the limiting section is located below the insertion section and its front end face abuts against the rear end face of the connecting plate.

[0011] The present invention is further configured such that: the connecting plate includes an upper connecting section and a lower connecting section, the upper positioning slot and the mounting protrusion are both located on the upper connecting section, the lower connecting section is provided with a lower positioning slot, the cover plate is provided with a lower positioning block corresponding to the lower positioning slot, and the upper positioning block and the lower positioning block are the same in shape and size.

[0012] The present invention is further configured to include a dustproof part fixedly installed on the front side of the lock cylinder. The lock cylinder is provided with a lock hole. The dustproof part includes a dustproof plate, a mounting base, and a torsion spring located between the dustproof plate and the lock cylinder. The mounting base is fixedly connected to the lock cylinder. The mounting base is provided with an inlet communicating with the lock hole. The dustproof plate is movably installed on the mounting base, and the projection of the lock hole facing forward falls on the dustproof plate.

[0013] The present invention is further configured such that: the cover plate is provided with a viewing groove corresponding to the dustproof plate, and the forward projection of the lock cylinder falls on the cover plate.

[0014] By adopting the above technical solution, when the gasket is installed on the rear side of the cover plate, the limiting protrusion on the cover plate will be inserted into the limiting slot of the gasket, and the limiting blocks of the gasket will be located on the upper and lower sides of the limiting protrusion, thereby enabling the gasket to determine its relative position with the cover plate. At the same time, since the limiting protrusion on the gasket will be inserted into the limiting groove between the first limiting plate and the second limiting plate, the gasket will be located on the rear side of the cover plate and the positions on both sides will be determined, thus facilitating the fixing of the gasket and the cover plate.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] like Figures 1-12As shown, this utility model discloses a car door handle assembly, including a cover plate 1, a lock cylinder 2, a handle 3 located on the front side of the cover plate 1, and a pad 4 located on the rear side of the cover plate 1. The pad 4 is detachably connected to the cover plate 1 by bolts or other means. The lock cylinder 2 is rotatably mounted on the cover plate 1 and a swing arm (not shown in the figure) is fixedly mounted on the rear side of the cover plate 1 by welding or other means. The cover plate 1 is installed on the car door. When it is necessary to open the car door, the key is inserted into the lock cylinder 2, which drives the swing arm on the lock cylinder 2 to separate from the object on the car door that cooperates with the swing arm, thereby applying force to the handle 3 to open the door (this is prior art and will not be described in detail here). The left side of the cover plate 1 has a limiting protrusion 11 protruding backward. The pad 4 has a limiting slot 41 corresponding to the limiting protrusion 11. The upper and lower sides of the pad 4 at the limiting slot 41 are provided with limiting blocks 42 that abut against the limiting protrusion 11. The cover plate 1 is located on the rear side of the car door. The right side is provided with a first limiting plate 12, a second limiting plate 13, and a limiting groove 14 located between the first limiting plate 12 and the second limiting plate 13. The pad 4 is provided with a limiting protrusion 43 protruding forward and inserted into the limiting groove 14. One end of the limiting protrusion 43 abuts against the first limiting plate 12, and the other end abuts against the second limiting plate 13. When the pad 4 is installed on the rear side of the cover plate 1, the limiting protrusion 11 on the cover plate 1 will be inserted into the limiting slot 41 of the pad 4. At this time, the limiting blocks 42 of the pad 4 are located on the upper and lower sides of the limiting protrusion 11, so that the relative position of the pad 4 and the cover plate 1 can be determined. At the same time, since the limiting protrusion 43 on the pad 4 will be inserted into the limiting groove 14 between the first limiting plate 12 and the second limiting plate 13, the pad 4 is located on the rear side of the cover plate 1 and the positions on both sides are determined, thus facilitating the fixing of the pad 4 and the cover plate 1.

[0036] The gasket 4 includes several mating plates 44. The cover plate 1 has a positioning post 15 protruding rearward for each mating plate 44. Each mating plate 44 has a positioning groove 441 for the corresponding positioning post 15 to be inserted. After the gasket 4 is placed on the rear side of the cover plate 1, the positioning post 15 on the cover plate 1 will be inserted into the corresponding positioning groove 441, thereby further improving the connection stability between the cover plate 1 and the gasket 4 when the relative positions of the cover plate 1 and the gasket 4 are determined.

[0037] The gasket 4 further includes a connecting plate 45, which includes fitting sleeves 451 located on the left and right sides. Each fitting sleeve 451 is provided with a mounting groove 4511. The cover plate 1 is provided with mounting protrusions 16 corresponding to each mounting groove 4511. The connection plate 45, fitting sleeves 451 and mounting protrusions 16 further increase the contact area between the gasket 4 and the cover plate 1, thereby further improving the connection stability after the cover plate 1 and the gasket 4 are connected.

[0038] The cover plate 1 has an upper positioning block 17 protruding between each mounting protrusion 16. Both the connecting plate 45 and the upper positioning block 17 are made of a material easily deformable, such as rubber. The connecting plate 45 has an upper positioning slot 452 corresponding to the upper positioning block 17. The upper positioning block 17 includes an insertion section 171 and a limiting section 172. The insertion section 171 is located within the upper positioning slot 452, and the limiting section 172 is located below the insertion section 171 with its front end face abutting against the rear end face of the connecting plate 45. Because the cover plate 1 has upper positioning blocks 17 on each mounting protrusion 16, after the mounting protrusions 16 of the cover plate 1 are respectively placed into the corresponding mounting slots 4511, the upper positioning blocks 17 on the cover plate 1 will be positioned within the upper positioning slot 4511. The upper positioning block 17 on the 1 will align with the upper positioning slot 452 on the connecting plate 45, thereby forcibly pushing the limiting segment 172 of the upper positioning block 17 past the upper positioning slot 452. At this time, the insertion segment 171 is located in the upper positioning slot 452 and the limiting segment 172 will abut against the connecting plate 45. Therefore, without the action of external force, due to the presence of the upper positioning block 17, the pad 4 will not separate from the cover plate 1 and can be stably positioned on the cover plate 1. When the pad 4 needs to be separated from the cover plate 1, the limiting segment 172 is bent, thereby forcibly pushing the limiting segment 172 forward past the upper positioning slot 452. At this time, due to the separation of the upper positioning block 17 from the upper positioning slot 452, the pad 4 can be separated from the cover plate 1.

[0039] Preferably, the connecting plate 45 includes an upper connecting section 453 and a lower connecting section 454. The upper positioning slot 452 and the mounting protrusion 16 are both located on the upper connecting section 453. The lower connecting section 454 is provided with a lower positioning slot 4541. The cover plate 1 is provided with a lower positioning block 18 corresponding to the lower positioning slot 4541. The upper positioning block 17 and the lower positioning block 18 have the same shape and size. Since the connecting plate 45 includes an upper connecting section 453 and a lower connecting section 454, when the gasket 4 and the cover plate 1 are installed together, the upper positioning block 17 will be located in the upper positioning slot 452 and the lower positioning block 18 will be located in the lower positioning slot 4541, thereby further improving the connection strength between the connecting plate 45 and the cover plate 1 and making the gasket 4 and the cover plate 1 stably connected together.

[0040] In addition, a dustproof part 5 is fixedly installed on the front side of the lock cylinder 2 by welding or other means. The lock cylinder 2 is provided with a keyhole 21. The dustproof part 5 includes a dustproof plate 51, a mounting base 52, and a torsion spring 53 located between the dustproof plate 51 and the lock cylinder 2. The mounting base 52 is fixedly connected to the lock cylinder 2 by welding or other means. The mounting base 52 is provided with an inlet 521 communicating with the keyhole 21. The dustproof plate 51 is movably installed on the mounting base 52, and the projection of the keyhole 21 facing forward falls on the dustproof plate 51. Since the dustproof plate 51 is movably installed on the mounting base 52, when it is not necessary to insert the key into the keyhole 21 of the lock cylinder 2, the dustproof plate 51 is inactive. The dustproof plate 51 is positioned behind the insertion port 521 and blocks the front of the lock hole 21, thus preventing dust and impurities from entering the lock hole 21. When a key is inserted, the key applies force to the dustproof plate 51, causing it to flip towards the lock cylinder 2, allowing the key to enter the lock hole 21 of the lock cylinder 2 through the insertion port 521. When the key is pulled out of the lock hole 21 of the lock cylinder 2, the torsion spring 53 causes the dustproof plate 51 to return to its original position in front of the lock hole 21, preventing the key from reaching the lock hole 21 through the insertion port 521.

[0041] Preferably, the cover plate 1 is provided with a viewing groove 19 corresponding to the dustproof plate 51. The forward projection of the lock cylinder 2 falls on the cover plate 1. Since the forward projection of the lock cylinder 2 falls on the cover plate 1, after the lock cylinder 2 is assembled on the cover plate 1, it is difficult for unauthorized personnel to access the circumference of the lock cylinder 2, so the car door can stably perform the anti-theft function when it is not unlocked.

[0042] It is also worth noting that a counterweight 6 is installed on the cover plate 1, which helps to balance the torque of the handle 3 during operation, making it easier and smoother to open the car door. By adjusting the position or weight of the counterweight 6, the movement of the handle 3 can be made smoother, reducing the force required by the user during use. With appropriate counterweight, the handle 3 will have a more natural rebound effect when pulled, which not only improves the comfort of use, but also reduces fatigue caused by improper force.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
