Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a locking mechanism for handrails and a vehicle. Background Technology

[0002] As an important part of vehicle interior design, seat armrests are becoming increasingly versatile in function. Modern vehicles typically integrate cup holders, storage compartments, and control buttons for functions such as airflow adjustment, seat heating, and massage. However, this multi-functional integration increases the armrest's weight, making it prone to wobbling during vehicle acceleration or braking. Therefore, locking mechanisms are usually added to the seat armrests to ensure stability.

[0003] The locking structure used in existing technologies mainly relies on the cooperation between a driven protrusion on the outer wall of the locking pin end and an active sliding groove. Specifically, the driven protrusion is embedded in the active sliding groove to form a sliding fit. When the bushing rotates, it can drive the locking pin to extend and retract axially, thereby achieving the purpose of locking the seat armrest.

[0004] However, existing locking mechanisms suffer from problems such as complex design, numerous components, and cumbersome assembly processes. Therefore, there is an urgent need to develop a locking mechanism with a simplified structure that meets the requirements for use with vehicle handrails. Utility Model Content

[0005] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides a locking mechanism and vehicle for handrails, which effectively solves the problems of complex design, numerous parts and cumbersome assembly process of the current locking structure.

[0006] According to a first aspect of the present invention, a locking mechanism for a handrail is provided for locking between a handrail mounting bracket and a handrail body.

The locking mechanism includes a locking pin housing, a driving assembly, a locking pin body, and a sliding groove. The locking pin housing is mounted on the handrail body, and the locking pin body passes through the locking pin housing. The sliding groove is disposed on the handrail mounting bracket, which has a through hole. The driving assembly drives the locking pin body to extend and retract along the axial direction of the locking pin body, so that the locking pin body can pass through the through hole or can be separated from the through hole.

[0007] Preferably, each end of the locking pin housing is provided with a locking pin body, and each end of the handrail mounting bracket is provided with a sliding groove corresponding to the locking pin body, and the driving component drives the two locking pin bodies.

[0008] Preferably, the sliding part has a mating hole and a sliding groove. The sliding groove is formed as an arc-shaped groove. One end of the sliding groove is connected to the mating hole. The mating hole is engaged with the through hole. The locking pin body can pass through the mating hole or can be separated from the mating hole.

[0009] Preferably, the handrail locking mechanism can switch between a locked handrail state and an unlocked handrail state. When the handrail locking mechanism is in the locked handrail state, the locking pin body extends and passes through the through hole and the mating hole. When the handrail locking mechanism is in the unlocked handrail state, the locking pin body retracts and separates from the through hole and the mating hole, and the locking pin body slides along the sliding groove.

[0010] Preferably, the end of the locking pin body that passes through the through hole is formed into a tapered end.

[0011] Preferably, the through hole is formed as an elliptical hole.

[0012] Preferably, the handrail body has a connecting hole for the locking pin body to pass through, and an insert is provided between the locking pin body and the connecting hole, the insert sleeved on the locking pin body.

[0013] Preferably, the locking pin housing includes a through portion and a connecting portion. The connecting portion is disposed on the outer periphery of the through portion. The locking pin housing is connected to the handrail body through the connecting portion. The through portion is provided with a hollow receiving cavity for the locking pin body to pass through. A return spring is provided between the locking pin body and the hollow receiving cavity. The return spring is sleeved on the locking pin body.

[0014] Preferably, a limiting groove is formed at the top of the hollow accommodating cavity, and the locking pin body includes a limiting pin, which passes through the limiting groove along the radial direction of the locking pin body.

[0015] According to a second aspect of the present invention, a vehicle is provided, wherein the vehicle includes a handrail locking mechanism as described above.

[0016] According to this utility model, the locking mechanism for handrails, through the cooperation of the locking pin housing, the drive assembly, the locking pin body, and the sliding groove, enables the handrail mounting bracket and the handrail body to be locked or unlocked, allowing the operator to fold or unfold the handrail body to meet usage needs. This handrail locking mechanism has a compact overall structure, is simple to assemble, and convenient to use. Due to its simple overall structure and few parts, it can reduce production costs while meeting user needs.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] According to a first aspect of this utility model, a locking mechanism for a handrail is provided, such as... Figures 1 to 6As shown, the armrest locking mechanism is used to lock and unlock the rear center armrest of a vehicle, enabling the rear center armrest to be folded up or unfolded. The rear center armrest may include an armrest mounting bracket 1 and an armrest body 2, which are connected by a rotating shaft 3. The end of the rotating shaft 3 can be fixed to the armrest mounting bracket 1 by a rotating fastening bolt. Since the connection method of the armrest mounting bracket 1, armrest body 2, and rotating shaft 3 is existing technology, it will not be described in detail here. Other existing structures can also be used to allow the armrest mounting bracket 1 and armrest body 2 to rotate relative to each other. Furthermore, in the accompanying drawings and embodiments, for ease of illustration, the armrest body 2 is only a part of the rear center armrest structure.

[0026] The handrail locking mechanism includes a locking pin housing 4, a drive assembly 5, a locking pin body 6, and a sliding groove 7. In the following description, reference will be made to... Figures 1 to 6 The detailed structure of the locking mechanism for the handrail includes the locking pin housing 4, the drive assembly 5, the locking pin body 6, and the sliding groove 7.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the locking pin housing 4 is installed on the handrail body 2, for example, by using fastening bolts for fixing. The locking pin body 6 passes through the locking pin housing 4 and can extend and retract within the locking pin housing 4, thereby unlocking or locking the handrail body 2.

[0028] Furthermore, the sliding groove 7 is disposed on the handrail mounting bracket 1, and the disposal method can be, for example, by providing a locking hole for positioning and using fastening bolts for fixation. In the embodiment, the material of the sliding groove 7 can be POM (polyoxymethylene plastic), which is a tough and elastic material with good creep resistance, geometric stability and impact resistance, and can also eliminate abnormal noise generated when the handrail rotates.

[0029] like Figure 3 As shown, the handrail mounting bracket 1 has a through hole 101. The drive assembly 5 drives the locking pin body 6 to extend and retract along the axial direction of the locking pin body 6. The axial direction of the locking pin body 6 can be, for example, as follows: Figure 2 In the left-right direction, the drive component 5 can be, for example, a pull cable assembly as in the prior art. One end of the pull cable assembly is installed on the handrail body 2, and the other end is connected to the locking pin body 6 via a connecting cable. The user uses the drive component 5, for example, the pull cable assembly, to drive the locking pin body 6 along... Figure 2The locking pin 6 can move left and right, allowing it to pass through the through hole 101 or separate from it. When the locking pin 6 passes through the through hole 101, the handrail mounting bracket 1 and the handrail body 2 cannot rotate relative to each other, and the handrail locking mechanism is in a locked state, preventing the user from adjusting the position of the handrail body 2 and maintaining its current state. When the locking pin 6 separates from the through hole 101, the handrail mounting bracket 1 and the handrail body 2 can rotate relative to each other, and the handrail locking mechanism is in an unlocked state, allowing the user to rotate the handrail body 2 to fold or unfold it.

[0030] This handrail locking mechanism, through the cooperation of the locking pin housing 4, drive assembly 5, locking pin body 6, and sliding groove 7, enables the handrail mounting bracket 1 and handrail body 2 to remain locked or unlocked, allowing the operator to fold or unfold the handrail body 2 to meet usage needs. This handrail locking mechanism has a compact overall structure, is simple to assemble, and convenient to use. Due to its simple overall structure and few parts, it can reduce production costs while meeting user needs.

[0031] Preferably, such as Figure 1 and Figure 2 As shown in the embodiment, in order to ensure the stable rotational movement of the handrail body 2, a locking pin body 6 is provided at both ends of the locking pin housing 4. Correspondingly, in order to achieve sliding while eliminating abnormal noise, a sliding groove 7 corresponding to the locking pin body 6 is provided at both ends of the handrail mounting bracket 1. The drive assembly 5 can drive the two locking pin bodies 6 simultaneously through two pull cables to ensure synchronous movement.

[0032] Preferably, such as Figure 6 As shown, in this embodiment, the sliding member 7 has a mating hole 701 and a sliding groove 702. The sliding groove 702 is formed as an arc-shaped groove, which can correspond to the rotation of the locking pin body 6 and restrict the position of the locking pin body 6, so that the locking pin body 6 can only move along the sliding groove 702. One end of the sliding groove 702 is connected to the mating hole 701, so that the sliding groove 702 can directly enter the sliding groove 702 when it is separated from the mating hole 701. The mating hole 701 is engaged with the through hole 101, and the size of the mating hole 701 corresponds to the size of the through hole 101, so that the sliding member 7 can be engaged with the handrail mounting bracket 1. The locking pin body 6 can pass through the mating hole 701 or can be separated from the mating hole 701 to achieve unlocking or locking.

[0033] Preferably, such as Figure 3 and Figure 6As shown, in the embodiment, both the through hole 101 and the mating hole 701 can be formed as elliptical holes. The elliptical holes can match the locking pin body 6 to solve the impact noise and gap problems that occur when the locking pin body 6 directly matches the metal.

[0034] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the handrail locking mechanism can switch between a locked state and an unlocked state. When the handrail locking mechanism is in the locked state, the locking pin body 6 extends and passes through the through hole 101 and the mating hole 701, locking the handrail mounting bracket 1 and the handrail body 2 relative to each other. When the handrail locking mechanism is in the unlocked state, the locking pin body 6 retracts and separates from the through hole 101 and the mating hole 701, allowing the handrail mounting bracket 1 and the handrail body 2 to rotate relative to each other. The retracted locking pin body 6 then slides along the sliding groove 702.

[0035] Preferably, such as Figure 5 As shown, in this embodiment, the end of the locking pin body 6 that passes through the through hole 101 is formed into a tapered end 601. The tapered end of the locking pin solves the problem of difficulty in aligning it, which in turn makes it difficult to lock.

[0036] Preferably, such as Figures 3 to 5 As shown, in this embodiment, the handrail body 2 has a connecting hole 201 for the locking pin body 6 to pass through. An insert 8 is provided between the locking pin body 6 and the connecting hole 201, and the insert 8 is fitted onto the locking pin body 6. The insert 8 can be made of a metal material such as steel or aluminum. The insert 8 can increase the contact surface inside the locking pin body 6, thereby solving the problem of internal shaking.

[0037] Preferably, such as Figure 5 As shown, in this embodiment, the locking pin housing 4 may include a through-hole portion 401 and a connecting portion 402. The connecting portion 402 is disposed on the outer periphery of the through-hole portion 401. The locking pin housing 4 is connected to the handrail body 2 through the connecting portion 402, and the connection method may be, for example, using a fastening bolt. The through-hole portion 401 is provided with a hollow receiving cavity for the locking pin body 6 to pass through. A return spring is provided between the locking pin body 6 and the hollow receiving cavity. The return spring is sleeved on the locking pin body 6, and the return spring can cause the locking pin body 6 to return to its original position.

[0038] Preferably, such as Figure 4 and Figure 5 As shown, in this embodiment, a limiting groove 403 is formed at the top of the hollow accommodating cavity, and the locking pin body 6 includes a limiting pin 602, which passes through the limiting groove 403 in the radial direction of the locking pin body 6. The cooperation between the limiting pin 602 and the limiting groove 403 can prevent the locking pin body 6 from coming out axially.

[0039] The locking mechanism of this handrail is used as follows: the user drives the locking pin body 6 along the drive component 5. Figure 2 The locking pin 6 moves left and right, allowing it to disengage from the through hole 101 of the armrest mounting bracket 1 and the mating hole 701 of the sliding member 7. After disengagement, the user can rotate the armrest body 2 to unfold or retract it. During rotation, the locking pin 6 slides along the sliding groove 702 of the sliding member 7, effectively eliminating any noise during rotation. To reset, the armrest body 2 is rotated in the opposite direction, causing the locking pin 6 to slide along the sliding groove 702 until it re-enters the through hole 101 and the mating hole 701, completing the locking process. At this point, the armrest body 2 cannot rotate.

[0040] This handrail locking mechanism, through the cooperation of the locking pin housing, drive assembly, locking pin body, and sliding groove, allows the handrail mounting bracket and handrail body to remain locked or unlocked, enabling the operator to fold or unfold the handrail body to meet usage needs. The handrail locking mechanism has a compact overall structure, is simple to assemble, and convenient to use. Due to its simple structure and few parts, it can reduce production costs while meeting user requirements.

[0041] Furthermore, according to a second aspect of the present invention, a vehicle is provided, the vehicle including the armrest locking mechanism described above.

[0042] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application.
