Description

Technical Field

[0001] This utility model belongs to the field of automotive handle technology, and in particular relates to an easy-to-replace automotive handle. Background Technology

[0002] With the development of society, the overall design of automobiles has evolved rapidly, and various functions have become increasingly user-friendly. Car door handles are no exception. A lot of effort has been put into their design, combining applicability and economy. Car door handles are a combination of safety, decoration and function in a car. Therefore, car door handles certainly play an important role, and their performance determines the grade of a car.

[0003] Although there are various types of car handlebars available today, some problems still exist. For example, most car handlebars currently use a modular design, consisting mainly of a handlebar assembly and an outer shell. These two parts generally use a snap-on-slot connection method. While this connection method can satisfy the installation and fixation of the handlebar assembly and the outer shell, as well as the subsequent disassembly and separation, since most of the snaps are made of plastic materials, they may deform during use. After deformation to a certain extent, the snaps may separate from the slots, easily causing the handlebar shell to fall off unexpectedly. This poses a safety hazard and also results in additional economic losses. Utility Model Content

[0004] This utility model provides an easy-to-replace car handle, aiming to solve the problem that although the current handle shell and handle assembly can meet the disassembly and assembly requirements, the connection between the two is not strong enough, and plastic deformation during use can easily cause them to separate.

[0005] This utility model is implemented as follows: an easy-to-replace car handle includes: a handle assembly, a handle housing, a mounting cavity, a locking mechanism, and an unlocking component. The handle assembly is installed on the car, the mounting cavity is located at the bottom of the handle housing, and the handle assembly is mated inside the mounting cavity.

[0006] The locking mechanism includes a support, a locking plate, a first docking groove, a locking groove, a locking rod, and a limiting component. The support is fixed to the inner wall of the handle assembly. The locking plate is rotatably connected to the inner cavity of the support. The first docking groove is provided on the support, and a second docking groove is provided on the side wall of the handle assembly. The first docking groove and the second docking groove are provided in a one-to-one correspondence. The locking groove is recessed in the locking plate, and the locking rod is fixed to the inner wall of the mounting cavity. The locking rod engages with the first docking groove and the second docking groove and is locked in the locking groove.

[0007] The support is also equipped with an unlocking component.

[0008] Preferably, the limiting component includes a snap-fit ​​groove, a limiting plate, and an abutment plate. The snap-fit ​​groove is disposed on one side of the locking plate, the limiting plate is rotatably connected to the inside of the support, the abutment plate is disposed at one end of the limiting plate and slides against the edge of the locking plate, and when the locking plate is in the locked state, one end of the abutment plate is snapped into the snap-fit ​​groove.

[0009] Preferably, the unlocking assembly includes a fixing rod, a torsion spring, and a connecting rod. The fixing rod is fixed to the support, the torsion spring is sleeved on the fixing rod, and the connecting rod is fixed to the locking plate. One end of the torsion spring abuts against the support and the other end abuts against the connecting rod.

[0010] Preferably, the unlocking component further includes an arc-shaped groove and a lever. The arc-shaped groove is disposed through the support, and the lever is fixed to the limiting plate and slidably engaged in the arc-shaped groove.

[0011] Preferably, at least two torsion springs are provided, both of which are connected to the support base with the fixing rod, and one end of one torsion spring abuts against the connecting rod, and the other end of the torsion spring abuts against the lever.

[0012] Preferably, a linkage block is rotatably connected to the lever, and the overall structure composed of the locking mechanism and the unlocking component is provided with multiple sets of linkage blocks at equal intervals within the handle assembly, and an active rod is provided between the multiple linkage blocks.

[0013] Compared with the prior art, the embodiments of this application have the following main advantages:

[0014] In this solution, the locking rod in the locking mechanism engages with the locking plate, thereby driving the locking plate to rotate and locking the locking rod in the locking groove. The limiting plate rotates synchronously until the abutment plate engages in the locking groove, locking the locking plate and achieving self-locking. This allows the handle assembly and handle housing to be quickly connected and locked. Simultaneously, by setting an unlocking component, the active rod in the unlocking component drives multiple levers and the limiting plate to rotate as a whole, causing the abutment plate to separate from the locking groove and achieving unlocking. The mechanical locking structure and spring pre-tensioning structure automatically lock when the handle housing and the assembly are engaged, avoiding the risk of plastic deformation of traditional plastic buckles. Moreover, the built-in active rod runs through all the nodes of the limiting plate, and a single-sided press can achieve multi-point synchronous release, realizing the quick unlocking and separation of the handle assembly and handle housing. It is simple, efficient and practical. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides an easy-to-replace car door handle, such as... Figure 1-5 As shown, it includes: handle assembly 1, handle housing 2, mounting cavity 3, locking mechanism 4 and unlocking component 5. The handle assembly 1 is installed on the vehicle, the mounting cavity 3 is located at the bottom of the handle housing 2, and the handle assembly 1 is mated in the mounting cavity 3.

[0024] The locking mechanism 4 includes a support 41, a locking plate 42, a first docking groove 43, a locking groove 44, a locking rod 45, and a limiting component. The support 41 is fixed on the inner wall of the handle assembly 1. The locking plate 42 is rotatably connected in the cavity inside the support 41. The first docking groove 43 is provided on the support 41, and a second docking groove 6 is provided on the side wall of the handle assembly 1. The first docking groove 43 and the second docking groove 6 are provided in a one-to-one correspondence. The locking groove 44 is recessed on the locking plate 42, and the locking rod 45 is fixed on the inner wall of the mounting cavity 3. The locking rod 45 engages with the first docking groove 43 and the second docking groove 6 and is locked in the locking groove 44.

[0025] The limiting component includes a snap-fit ​​groove 46, a limiting plate 47, and an abutment plate 48. The snap-fit ​​groove 46 is located on one side of the locking plate 42. The limiting plate 47 is rotatably connected to the inside of the support seat 41. The abutment plate 48 is located at one end of the limiting plate 47 and slides against the edge of the locking plate 42. When the locking plate 42 is in the locked state, one end of the abutment plate 48 is snapped into the snap-fit ​​groove 46.

[0026] The support 41 is also provided with an unlocking component 5, which includes a fixing rod 51, a torsion spring 52 and a connecting rod 53. The fixing rod 51 is fixed on the support 41, the torsion spring 52 is sleeved on the fixing rod 51, and the connecting rod 53 is fixed on the locking plate 42. One end of the torsion spring 52 abuts against the support 41 and the other end abuts against the connecting rod 53.

[0027] The unlocking component 5 also includes an arc-shaped slide 54 and a lever 55. The arc-shaped slide 54 is disposed through the support 41, and the lever 55 is fixed on the limiting plate 47 and slidably engaged in the arc-shaped slide 54.

[0028] It should be noted that existing car handlebars generally adopt a modular design, mainly consisting of two parts: the handlebar assembly and the outer shell. These two parts typically use a snap-fit / slot connection method. While this method satisfies the installation and fixation of the handlebar assembly and the outer shell, as well as subsequent disassembly and separation, the snaps are mostly made of plastic materials. During use, the snaps are susceptible to plastic deformation. After deformation to a certain extent, the snaps may separate from the slots, easily causing the handlebar shell to accidentally detach, posing a safety hazard and resulting in additional economic losses. To solve this problem, this solution includes a locking mechanism 4 and an unlocking component 5. The locking mechanism 4 uses a locking rod 45 to engage with a locking plate 42, thereby rotating the locking plate 42 and locking the handlebar. The lever 45 is locked in the locking groove 44, and the limiting plate 47 rotates synchronously until the abutment plate 48 engages in the locking groove 46, locking the locking plate 42 and achieving self-locking. This allows the handle assembly 1 and the handle housing 2 to be quickly connected and locked. At the same time, by setting the unlocking component 5, the active lever 57 in the unlocking component 5 drives multiple levers 55 and the limiting plate 47 to rotate as a whole, causing the abutment plate 48 to separate from the locking groove 46 and achieving unlocking. The mechanical locking structure and spring pre-tightening structure automatically lock when the handle housing and the assembly are connected, avoiding the risk of plastic deformation of traditional plastic buckles. The built-in active lever 57 runs through all nodes of the limiting plate 47, and multi-point synchronous release can be achieved by pressing on one side, realizing the quick unlocking and separation of the handle assembly 1 and the handle housing 2. It is simple, efficient and practical.

[0029] Specifically, in this embodiment, the solution mainly includes a handle assembly 1, a handle housing 2, a mounting cavity 3, a locking mechanism 4, and an unlocking component 5. In use, the handle assembly 1 is connected to the mounting cavity 3 of the handle housing 2. During connection, the locking rod 45 is connected to the first docking groove 43 and the second docking groove 6, and abuts against the locking groove 44. At the same time, the locking plate 42 is pushed to rotate. At this time, the active rod 57 rotates under the elastic force of the torsion spring 52 until the abutment plate 48 abuts and locks in the locking groove 46, thus locking the locking plate 42. When unlocking and disassembly are required, the active rod 57 is pushed, which drives multiple levers 55 to slide in the arc-shaped slide groove 54. At this time, multiple limiting plates 47 rotate synchronously, causing one end of the abutment plate 48 to separate from the locking groove 46. At this time, the locking plate 42 rotates and resets under the elastic force of the torsion spring 52, and the locking rod 45 separates from the locking groove 44.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, at least two torsion springs 52 are provided. Both torsion springs 52 are connected to the support 41 in conjunction with the fixing rod 51. One end of one torsion spring 52 abuts against the connecting rod 53, and one end of the other torsion spring 52 abuts against the lever 55.

[0031] In this embodiment, the spring force of the torsion spring 52 enables the locking plate 42 and the limiting plate 47 to be quickly reset respectively.

[0032] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, a linkage block 56 is rotatably connected to the lever 55. The overall structure composed of the locking mechanism 4 and the unlocking component 5 is arranged in multiple sets at equal intervals in the handle assembly 1, and an active rod 57 is arranged between multiple linkage blocks 56. An adjustment groove 7 is provided through one end of the handle assembly 1 and the handle housing 2, and the adjustment groove 7 is arranged in a one-to-one correspondence with the active rod 57.

[0033] In this embodiment, the adjustment groove 7 allows the operator to directly operate the drive lever 57 from outside the car handle, which is simple and efficient.
