The existing door handle mainly consists of a base for fixed installation with the door and a handle that is rotatably set on the base and connected to the door lock mechanism through a linkage cable. Since the doors of heavy trucks are heavy, the structure of the existing door handle assembly to realize the transmission connection with the door lock mechanism is relatively complex. Under heavy operating loads, the transmission is prone to jamming, which affects the normal opening of the door.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] As shown in the figure, a heavy-duty truck door handle assembly includes a base 1 and a handle 2. A bracket 11 is formed on the inner wall of the base 1. A connecting frame 4 is rotatably mounted on the bracket 11 via a first pin 3. One end of the handle 2 is rotatably mounted on the base 1 via a second pin 5, and the other end has a first transmission arm 21 in an arc shape with the second pin 5 as the center. The first transmission arm 21 passes through a swing window 12 opened on the base 1, and a transmission groove 22 is opened on each of the two sides of the end of the first transmission arm 21 passing through the swing window 12. Two second transmission arms 41 are formed on the connecting frame 4 and are respectively held in the two transmission grooves 22. A torsion spring 6 is sleeved on the first pin 3, with its two ends acting on the bracket 11 and the connecting frame 4 respectively.

[0025] Specifically, the connecting frame 4 is rotatably mounted on the bracket 11: the bracket 11 has two opposing first mounting plates 111 and second mounting plates 112; the connecting frame 4 has a connecting post 42; the connecting frame 4 is inserted into the second mounting plate 112 such that the connecting post 42 is located between the first mounting plate 111 and the second mounting plate 112; the first pin 3 passes sequentially through the connecting frame 4, the second mounting plate 112, the connecting post 42, and the first mounting plate 111, and is connected to a retaining ring; the torsion spring 6 is sleeved on the connecting post 42. Between the first mounting plate 111 and the second mounting plate 112, the above structure allows the first mounting plate 111 and the second mounting plate 112 to axially limit the connecting pile 42 located between them, preventing the connecting pile 42 from shifting during the rotation of the connecting frame 4, thus ensuring the stability of the connecting frame 4 during rotation. This allows the second transmission arm 41 to cooperate more stably with the first transmission arm 21 for transmission. The torsion spring 6 located between the first mounting plate 111 and the second mounting plate 112 is also limited, ensuring the stability of the torsion spring 6 when it operates.

[0026] In the above structure, the base 1 is mounted on the car door. The buckle rotatably mounted on the connecting frame 4 is connected to the door lock mechanism via a connecting rod cable. When the car door needs to be opened, pulling the handle 2 outward causes the free end of the handle 2 to swing outward. The handle 2 drives the first transmission arm 21 at its free end to swing around the second axis and pass through the swing window 12. The second transmission arm 41, through two transmission grooves 22, simultaneously drives two second transmission arms 41 to swing around the first pin 3, thereby rotating the connecting frame 4 and torsion spring 6. The connecting frame 4 then drives the door lock mechanism via the buckle and connecting rod cable to open the car door. After releasing the handle 2, the connecting frame 4 rotates back to its original position under the restoring force of the torsion spring 6, and then drives the first transmission arm 21 to swing back to its original position via the second transmission arm 41, causing the handle 2 to return to the base 1. Therefore, in the above structure, through… The linkage between the first transmission arm 21 and the connecting frame 4 enables the transmission between the handle 2 and the door lock mechanism. The two second transmission arms 41 on the connecting frame 4 are located in the two transmission grooves 22 respectively, so that the connecting frame 4 is clamped on the first transmission arm 21, making the transmission connection between the connecting frame 4 and the first transmission arm 21 very stable. When the handle 2 swings, the first transmission arm 21 can move very stably within the swing window 12 of the base 1, so that the action of pulling the handle 2 to swing can be transmitted very stably to the connecting frame 4 through the first transmission arm 21, causing the connecting frame 4 to rotate and drive the door lock mechanism to move. This ensures the stability when pulling the handle 2 to open the car door. Moreover, the transmission structure composed of the first transmission arm 21, the transmission groove 22 and the second transmission arm 41 is simple and reliable, and is not prone to jamming under load, ensuring the normal opening of the car door.

[0027] Additionally, a first limiting plate 23 is formed at one end of the handle 2 that is rotatably connected to the base 1. A first limiting groove 13 that is adapted to the limiting plate is formed on the outer wall of the base 1. When the handle 2 swings back to the base 1 under the restoring force of the torsion spring 6, the first limiting plate 23 abuts against the second limiting groove 14 to limit the swing of the handle 2, ensuring that the handle 2 can accurately return to its original position and remain on the base 1, thereby enhancing the stability of the handle 2 during operation.

[0028] Additionally, a second limiting plate 24 is formed at the end of the handle 2 connected to the first transmission arm 21, and a second limiting groove 14 adapted to the second limiting plate 24 is formed on the outer wall of the base 1. When the handle 2 swings back to the base 1 under the restoring force of the torsion spring 6, the second limiting plate 24 abuts against the second limiting groove 14 to limit the swing of the handle 2, ensuring that the handle 2 can accurately return to the base 1, thereby enhancing the stability of the handle 2 during operation.

[0029] Additionally, a shock-absorbing washer 15 is fitted onto the first transmission arm 21 to fit against the second limiting plate 24. The shock-absorbing washer 15 can rotate with the handle 2 and abut against the bottom of the second limiting groove 14. When the second limiting plate 24 abuts against the second limiting groove 14, the shock-absorbing washer 15 abuts against the bottom of the second limiting groove 14, providing shock absorption for the handle 2 to reset and swing, reducing the noise when the handle 2 resets and swings, and improving the user experience.

[0030] Additionally, two mounting feet 16 are formed on the inner wall of the base 1 on both sides of the bracket 11. Nut inserts 17 are provided on the mounting feet 16. The mounting feet 16 cooperate with the components on the car door. The bolts passing through the car door components are screwed into the nut inserts 17 to achieve the fixed installation of the base 1 and the car door. The operation is simple and convenient. It is convenient for the base 1 and the door handle assembly to be disassembled and assembled, making the door handle assembly easy to maintain.

[0031] Additionally, a sealing gasket 7 is provided on the inner wall of the base 1, and a limiting annular groove 18 is formed on the edge of the inner wall of the base 1. A limiting protrusion 71 is formed on the sealing gasket 7 and is held within the limiting annular groove 18. When the base 1 is fixedly installed on the car door, the sealing gasket 7 is pressed between the edge of the base 1 and the car door to play a sealing role, preventing rainwater from entering the door handle assembly and causing corrosion to the first transmission arm 21, connecting frame 4 and torsion spring 6 and other transmission components, thereby ensuring the durability of the door handle assembly. The limiting protrusion 71 cooperates with the limiting annular groove 18 to limit the relative displacement between the sealing gasket 7 and the base 1, ensuring that the sealing gasket 7 is stably held between the base 1 and the car door to achieve the sealing function.

[0032] In addition, the sealing gasket 7 is provided with a plurality of limiting holes 72, and the inner wall of the base 1 is provided with a plurality of limiting posts 19 that are inserted into the plurality of limiting holes 72. The limiting posts 19 cooperate with the limiting holes 72 to provide further limiting for the relative displacement between the sealing gasket 7 and the base 1, thereby further ensuring the stability of the sealing gasket 7.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
