Description

Technical Field

[0001] This utility model relates to the field of handrail locking structures, and in particular to a locking structure and handrail. Background Technology

[0002] In the field of automotive armrest design, traditional unlocking structures typically employ simple buckles or button-type locking mechanisms, which suffer from problems such as inconvenience in operation and insufficient reliability.

[0003] Existing button-locking mechanisms commonly use a push-push maze structure to control armrest locking. Due to the small size and low strength of maze locks, they may malfunction in emergency situations, posing a safety hazard. This structure relies on a specific push-button sequence for locking and unlocking; during sudden braking or a collision, inertia may cause accidental unlocking, endangering occupant safety. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A locking structure includes a pop-out component disposed within a handrail housing, the pop-out component having a locking mechanism for locking with the handrail housing, the locking mechanism engaging with a locking rod at the handrail housing via a rotary latch to achieve locking.

[0006] In a preferred embodiment of the present invention, the locking mechanism further includes a locking pin inserted on the latch to restrict rotation and a pressing actuator that drives the locking pin to move and unlock via a guide structure.

[0007] In a preferred embodiment of this utility model, the locking pin guide structure is a guide slope on the side of the pressing actuator adjacent to the locking pin. When the pressing actuator moves toward the locking pin, the guide slope pushes the locking pin away from the latch to achieve unlocking.

[0008] In a preferred embodiment of the present invention, the locking pin and the pressing actuator also have a return spring, which, in conjunction with the guide structure, gives the pressing actuator a tendency to move away from the locking pin.

[0009] In a preferred embodiment of the present invention, the latch has a locking groove and a locking opening located on both sides of the latch hinge point. When the locking pin is inserted into the locking groove, the latch cannot rotate and the locking opening engages with the locking rod to lock.

[0010] In a preferred embodiment of the present invention, the latch is further provided with a spring-loaded component for driving the latch to rotate and unlock. The latch has a guide surface on its outer peripheral surface, and the guide surface protrudes from one side of the locking groove. When the locking pin disengages from the locking pin locking groove to unlock, the spring-loaded component causes the latch to rotate, and the guide surface lifts the locking pin.

[0011] In a preferred embodiment of this utility model, the locking port is composed of a first locking surface and a second locking surface, and the locking rod drives the latch to rotate in two different directions through the first locking surface or the second locking surface, thereby controlling the locking of the locking pin.

[0012] Handrail, including any of the locking structures described above.

[0013] In a preferred embodiment of the present invention, a storage compartment and a cup holder are also provided in the armrest.

[0014] The beneficial effects of this utility model are as follows:

[0015] The locking structure provided by this utility model has two aspects. First, the locking mechanism employs a dual limiting mechanism of a rotating latch and a locking pin, combined with a return spring, to ensure a stable lock and locking strength. Second, the smooth sliding of the ejector component is achieved through the coordinated action of a coil spring and a damper. Attached Figure Description

These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.

[0031] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0032] Figure 1 and Figure 2The internal structure of the armrest involving the unlocking mechanism is shown. The pop-out component 200 is slidably disposed within the housing 100. Damped sliding between the pop-out component 200 and the housing 100 is achieved through a damper 203 located adjacent to the housing 100 and a rack 102 on the housing 100. The pop-out component 200 and the housing 100 form an integral unit and can be placed within an outer housing to form a complete armrest structure.

[0033] refer to Figure 3 and Figure 4 A coil spring 201 is provided on the pop-out component 200. The coil spring 201 is positioned at the rear of the pop-out component 200, and the end 202 of the coil spring is pulled out and fixed at the front of the housing 100. This allows the pop-out component 200 to move forward and extend when there is no locking point between it and the housing 100, driven by the coil spring 201.

[0034] refer to Figures 5 to 7 A locking mechanism 300 is provided inside the pop-out component 200. The locking mechanism 300 is used to lock the pop-out component 200 and the housing 100, so that the pop-out component 200 cannot slide freely relative to the housing 100.

[0035] Specifically, the locking mechanism 300 includes a rotating latch 310 located near the housing 100 for coupling and locking with a locking rod 110 on the housing 100, a locking pin 340 for limiting the rotation of the latch 310, and a pressing actuator 320. The locking pin 340 is slidably mounted on a bracket 330 fixed within the ejector component 200. The pressing actuator 320 is inserted into the locking pin 340 from the side. A first return spring 331 is arranged between the pressing actuator 320 and the bracket 330, and a second return spring 332 is arranged between the locking pin 340 and the bracket 330. The pressing actuator 320 contacts the first guide surface 342 of the locking pin 340 via a second guide surface 321. When the pressing actuator 320 is operated to move toward the locking pin 340, the second guide surface 321 pushes the first guide surface 321, causing the locking pin 340 to move upward along the bracket 330. When the external force applied to the pressing actuator 320 disappears, the pressing actuator 320 moves in the opposite direction to reset under the action of the first reset spring 331 and the locking pin 340 moves in the opposite direction to reset under the action of the second reset spring 332.

[0036] In some embodiments, the first guide surface 342 and the second guide surface 321 are inclined relative to the direction of movement of the locking pin 340.

[0037] refer to Figure 8The outer peripheral surface of the latch 310 is provided with a locking opening 312 that engages with the locking bar 110 on the housing 100 and a locking groove 316 that is limited by the locking pin 340. The hinge point 317 of the latch 310 is located at the bottom of the locking pin 340, while the locking opening 312 and the locking groove 316 are located on both sides of the hinge point 317. When the locking pin 340 is inserted into the locking groove 316, the locking opening 312 engages with the locking bar 110, and the latch 310 cannot rotate freely, thereby achieving relative locking between the ejector component 200 and the housing 100.

[0038] refer to Figure 9 and Figure 10 The locking opening 312 is formed by a first locking surface 313 on the front side and a second locking surface 314 on the rear side. The latch 310 also has at least one torsion spring 311 that always drives it to rotate in one direction. When the latch 310 is not limited by the locking pin 340 (i.e., the locking pin 340 is pulled up by force) and the ejector component 200 is not operated by external force, the latch 310 rotates clockwise to push the locking rod 110, the locking opening 312 disengages from the locking rod 110, the front end position 341 of the locking pin 340 is pushed up by the third guide surface 315 protruding on the front side of the locking groove 316, and the latch 310 rotates to the locking groove 316 and the stop point 204. When the pop-out component 200 is pushed by an external force to move toward the housing 100 to close, the locking rod 110 pushes the latch 310 to rotate through the second locking surface 314, and the locking pin 340 moves and rises along the third guide surface 315 toward the locking groove 316 and finally falls into the locking groove 316. The locking rod 110 is limited by the first locking surface 313, and the pop-out component 200 cannot slide freely relative to the housing 100.

[0039] In some implementations, a cup holder or electronic interactive components may be arranged inside the pop-up component 200.
