For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] Combination Figure 1-3 As shown, this embodiment provides a handrail including a fixed member 1 and a handrail plate 2 that rotates relative to the fixed member 1. A handrail angle locking mechanism is provided between the fixed member 1 and the handrail plate 2. The handrail angle locking mechanism is a concave-convex locking mechanism. At least a portion of the handrail angle locking mechanism is provided on the fixed member 1, and the remaining portion is provided on a control component that switches the handrail angle locking mechanism back and forth between a locked state and a unlocked state.

[0039] It is understood that in this embodiment, the armrest plate 2 can be rotated relative to the fixed component 1 to facilitate the adjustment of the setting angle of the armrest plate 2. The locking mechanism of the armrest plate 2 and the fixed component 1 is controlled to lock the armrest plate 2 and the fixed component 1, ensuring the relative fixation of the armrest plate 2 and the support stability of the armrest. The control component can switch the armrest angle locking mechanism between the locked state and the unlocked state to adapt to different user needs and improve the convenience of armrest adjustment.

[0040] In one specific embodiment of this application, the control component includes a locking control rod 41 rotatably connected to the handrail plate 2, the remaining part of the handrail angle locking mechanism is disposed on the locking control rod 41, and also includes a rotation drive device for driving the locking control rod 41 to rotate.

[0041] Specifically, the rotation drive device includes the following two options:

[0042] Option 1:

[0043] The rotation drive device includes a gear and a rack that mesh with each other. The gear is located at the other end of the locking control lever 41 that is rotatably connected to the handrail plate 2, and the rack is located at least a portion of the drive member 421 that extends into the handrail plate 2.

[0044] Specifically, in this embodiment, a rack is provided on at least a portion of the drive member 421 that extends into the handrail plate 2, and a gear that meshes with the rack is provided on the other end of the locking control rod 41 that is rotatably connected to the handrail plate 2. When the drive member 421 is pushed or pulled, the rack moves linearly and drives the gear to rotate. The locking control rod 41 rotates under the action of the gear, so that the handrail angle locking mechanism can switch between the locked state and the unlocked state.

[0045] Option 2:

[0046] Combination Figure 6-8 as well as Figure 12-14 As shown, the rotation drive device includes a locking groove 422 and a locking part 423 rotatably disposed in the locking groove 422. The locking groove 422 is disposed on at least a portion of the drive member 421 extending into the handrail plate 2. The locking part 423 is fixedly disposed on the other end of the locking control rod 41 rotatably connected to the handrail plate 2. The locking groove 422 is provided with a locking space 4221 that can accommodate at least a portion of the locking part 423. When the handrail angle locking mechanism is in the locked state, at least a portion of the locking part 423 is located in the locking space 4221.

[0047] Specifically, in this embodiment, the latching groove 422 is preferably an L-shaped groove, and the latching part 423 is fixedly disposed on the side wall of the other end of the locking control rod 41 that is rotatably connected to the handrail plate 2. At least a portion of the inner right-angled wall of the latching part 423 near the L-shaped groove is an arc-shaped structural surface. When the locking control rod 41 is rotated, when the latching part 423 enters the locking space 4221 of the latching groove 422 through the arc-shaped structural surface, the handrail angle locking mechanism is in the locked state; when the latching part 423 completely disengages from the locking space 4221 of the latching groove 422, the handrail angle locking mechanism is in the unlocked state.

[0048] Specifically, in this embodiment, a locking groove 422 is provided on at least a portion of the drive member 421 that extends into the handrail plate 2, and a locking part 423 is provided on the other end of the locking control rod 41 that is rotatably connected to the handrail plate 2. Pushing and pulling the drive member 421 causes the locking part 423 to rotate within the locking groove 422 in the drive member 421, thereby driving the locking control member to rotate, so that the handrail angle locking mechanism can switch between the locked state and the unlocked state.

[0049] It is understood that in this embodiment, the control component achieves precise control of the locking control lever 41 through different rotation drive devices. By controlling the rotation of the locking control lever 41, the handrail angle locking mechanism can be smoothly switched between the locked and unlocked states.

[0050] In one specific embodiment of this application, the control component includes a locking control rod 41 with one end hinged to the handrail plate 2, the remaining part of the handrail angle locking mechanism is disposed on the locking control rod 41, and also includes a swing drive device for driving the locking control rod 41 to swing around the hinge point.

[0051] Specifically, the swing drive device includes the following two solutions:

[0052] Option 1:

[0053] The swing drive device is a side-push type drive structure. The side-push type drive structure includes at least a portion of a drive member 421 extending into the handrail plate 2, and a locking control lever 41 at an end away from the hinge point, with the end of the locking control lever 41 away from the hinge point connected to at least a portion of the drive member 421 extending into the handrail plate 2. The push-pull drive member 421 drives the locking control lever 41 to swing horizontally around the hinge point, allowing the handrail angle locking mechanism to switch between a locked state and an unlocked state.

[0054] Specifically, a spring is provided between the end of the drive member 421 that extends into the handrail plate 2 and the handrail plate 2, the spring being preferably a spring, to prevent the locking control rod 41 from moving laterally during the rotation of the handrail plate 2.

[0055] Option 2:

[0056] The swing drive device is a nodding-type drive structure. The nodding-type drive structure includes at least a portion of a drive member 421 extending into the handrail plate 2, and a locking control lever 41 at one end away from the hinge point. The end of the locking control lever away from the hinge point is connected to at least the portion of the drive member 421 extending into the handrail plate 2, and the drive member 421 is rotatably mounted on the handrail plate 2 via a pivot. Pressing the end of the drive member 421 located outside the handrail plate 2 causes the locking control lever 41 to swing up and down around the hinge point, allowing the handrail angle locking mechanism to switch between a locked state and a unlocked state.

[0057] Specifically, in this embodiment, an elastic member is provided between one end of the drive member 421 that extends into the handrail plate 2 and the inner bottom surface of the handrail plate 2. The elastic member is preferably a spring, so as to prevent the handrail angle locking mechanism from automatically releasing the lock without external force.

[0058] Understandably, the control components in this solution control the locking control lever 41 to swing around the intersection point via different swing drive devices, thereby achieving automatic locking and unlocking of the handrail angle. Different swing drive devices can achieve precise control and rapid switching of the handrail angle through simple push-pull or press actions, while the elastic component ensures the stability and durability of the entire structure.

[0059] Combination Figure 3-5As shown, in one specific embodiment of this application, the handrail angle locking mechanism includes a locking part 31 and a locking groove 32. Either the locking part 31 or the locking groove 32 is disposed on the fixing member 1, and the other is disposed on the control component.

[0060] Specifically, in this embodiment, the locking groove 32 is preferably an elliptical spherical recessed groove.

[0061] Specifically, the armrest angle locking mechanism includes the following two configuration options:

[0062] Option 1:

[0063] There is at least one locking part 31 and several locking grooves 32 arranged in a circular pattern. The locking part 31 can form a locking state with any one of the locking grooves 32.

[0064] Option 2:

[0065] There is at least one locking groove 32 and several locking parts 31 arranged in a circular pattern. The locking groove 32 can form a locking state with any one of the locking parts 31.

[0066] It is understood that in this embodiment, the handrail angle locking mechanism consists of a locking part 31 and a locking groove 32 that can cooperate with each other. The cooperation state of the locking part 31 and the locking groove 32 is controlled by a control component. When the locking part 31 and the locking groove 32 cooperate, they enter the locking state, and the angle of the handrail plate 2 relative to the fixed member 1 is locked, ensuring the safety and stability of use.

[0067] Combination Figure 1-2 as well as Figure 9-11 As shown, in one specific embodiment of this application, a linear moving block 5 is movably connected to the handrail 2. The linear moving block 5 is rotatably connected to the fixed member 1. A moving block locking mechanism is provided between the linear moving block 5 and the handrail 2. At least a portion of the moving block locking mechanism is located on at least one side of the linear moving block 5, and the remaining portion is located on the handrail 2. When the handrail 2 is in the locked state, at least a portion of the control component moves with the linear moving block 5.

[0068] Specifically, in this embodiment, one end of the fixing member 1 is fixedly mounted on the support of the handrail, and the other end extends into the interior of the handrail 2 through the strip hole 21. The handrail 2 slides with the fixing member 1 through the strip hole 21.

[0069] Specifically, the movable locking mechanism in this embodiment includes a movable locking block and a movable locking groove 64. The movable locking block and the movable locking groove 64 cooperate to form a locked state. One of the movable locking block and the movable locking groove 64 is disposed on the inner side wall of the handrail plate 2 parallel to the strip hole 21, and the other is disposed on at least one side of the linear moving block 5 parallel to the strip hole 21 by means of an elastic member. The elastic member is preferably a spring.

[0070] Specifically, the movable locking mechanism includes the following two configuration options:

[0071] Option 1:

[0072] There is at least one movable locking block and several movable locking grooves 64 distributed parallel to the strip hole 21. The movable locking block cooperates with any one of the movable locking grooves 64 to form a locking state.

[0073] Option 2:

[0074] There is at least one movable locking groove 64 and several movable locking blocks distributed parallel to the strip hole 21. The movable locking groove 64 cooperates with any one of the movable locking blocks to form a locking state.

[0075] It is understood that the movable locking mechanism in this embodiment consists of a movable locking block and a movable locking groove 64 that can cooperate with each other. Since the movable locking block is set on the linear movable block 5 through an elastic member, when the handrail 2 moves relative to the linear movable block 5, the elastic member provides a compression fit space for the movable locking block. When adjusted to the required position, the elastic member automatically pushes the movable locking block into the movable locking groove 64, thereby realizing the cooperation and locking of the movable locking block and the movable locking groove 64, and thus realizing the relative fixation of the linear movable block 5 and the handrail 2.

[0076] It is understood that, in this embodiment, by providing an axially movable moving part 61 on the locking control lever 41 and at least partially located on the linear moving block 5, in addition to achieving the switching control of the locking state and unlocking state through the locking control lever 41, it can also provide linear motion guidance for the linear moving block 5 during the position adjustment process relative to the handrail 2, thereby avoiding the offset of the handrail 2.

[0077] In one specific embodiment of this application, a moving member 61 is provided on the locking control rod 41, which is circumferentially fixed and axially movable relative to the locking control rod 41. A locking part 31 or a locking groove 32 is provided on the moving member 61. A receiving groove 62 is provided on the linear moving block 5 for at least a portion of the moving member 61 to be accommodated. When the locking part 31 and the locking groove 32 are in the locked state, at least a portion of the moving member 61 is in the receiving groove 62, and the moving member 61 moves linearly with the linear moving block 5.

[0078] Specifically, when the swing drive device is a side-push drive device, the axial length of the moving part 61 in the locking control rod 41 is shorter than the groove width of the receiving groove 62 in the axial direction of the locking control rod 41, and the groove width of the clearance groove 63 in the width direction of the handrail is greater than the outer diameter of the locking control rod 41.

[0079] Specifically, when the swing drive device is a nodding type drive structure, the axial length of the moving part 61 in the locking control rod 41 is shorter than the groove width of the receiving groove 62 in the axial direction of the locking control rod 41.

[0080] It is understood that in this embodiment, the moving part 61 is provided with a locking part 31 or a locking groove 32, and the moving part 61 is installed on the locking control rod 41 by means of circumferential fixation, so as to ensure that the handrail angle locking mechanism switches the handrail plate 2 relative to the fixed member between the locked state and the unlocked state by controlling the locking control rod 41. At the same time, the moving part 61 is axially slidably disposed on the locking control rod 41, and at least a part of the moving part 61 is located in the receiving groove 62 of the linear moving block 5. When the linear moving block 5 slides relative to the handrail plate 2, the moving part 61 will also slide relative to the handrail plate 2, but the relative distance between the moving part 61 and the fixed member 1 remains unchanged, thereby ensuring that the relative distance between the locking part 31 and the locking groove 32 remains unchanged, so as to realize the normal operation of the handrail angle locking mechanism.

[0081] In one specific embodiment of this application, at least a portion of the avoidance groove 63 of the avoidance locking control rod 41 is provided on the linear moving block 5, and the receiving groove 62 and the avoidance groove 63 are connected.

[0082] It is understood that, in this embodiment, by providing the clearance groove 63, the normal operation of the locking function is ensured when the swing drive device drives the locking control rod 41 to swing around the hinge point.

[0083] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
