Description

Technical Field

[0001] This utility model belongs to the field of furniture accessories technology, specifically relating to a gaming chair armrest position adjustment mechanism with multi-angle adjustment and locking functions. Background Technology

[0002] Most existing gaming chair armrest adjustment mechanisms use traditional knob locking or friction locking methods. These designs have several limitations in practical use: First, in terms of adjustment angle, existing mechanisms typically only allow rotation in one direction, failing to meet users' needs for multi-dimensional adjustment. Second, regarding locking reliability, knob locking structures are prone to wear and tear over time, while friction locking methods suffer from reduced friction due to material aging, eventually leading to loosening. Third, in terms of human-computer interaction, existing mechanisms generally lack effective operational feedback mechanisms; users cannot confirm the locking status through touch or hearing and often need to repeatedly check. Finally, in terms of ease of operation, traditional adjustment methods often require multiple steps—unlocking, adjusting, and finally locking—a time-consuming and laborious process that makes it difficult to quickly and accurately adjust to the ideal position. These shortcomings seriously affect the user experience and the product's market competitiveness. Utility Model Content

[0003] The purpose of this invention is to provide a gaming chair armrest position adjustment mechanism that is easy to operate, has reliable locking, and provides tactile feedback.

A first rotating shaft is provided on the armrest base, and the armrest is rotatably connected to the armrest base via the first rotating shaft. A second rotating shaft is provided on the support arm, and the armrest base is rotatably connected to the support arm via the second rotating shaft. A locking structure is provided within the armrest base, the locking structure including a locking pin and at least one positioning hole provided on the support arm. The locking pin can be inserted into the positioning hole to lock the armrest base and the support arm. A spring is also provided within the armrest base, the spring abutting against the locking pin to keep it inserted into the positioning hole.

[0006] Furthermore, the locking pin is provided with an unlocking lever, which can be moved to allow the locking pin to overcome the spring force and disengage from the positioning hole.

[0007] Furthermore, the locking pin is provided with a positioning ball assembly, which includes a ball and a ball spring; the armrest seat is provided with a ball groove that cooperates with the ball; when the locking pin is inserted into the positioning hole, the ball is engaged in the ball groove under the action of the ball spring; when the ball is engaged in or disengaged from the ball groove, a "tick" sound is emitted.

[0008] Furthermore, the support arm is provided with four positioning holes, and the angular interval between adjacent positioning holes is 90°.

[0009] Furthermore, the end of the locking pin has a tapered structure, which facilitates insertion into the positioning hole.

[0010] Furthermore, at the joint surface between the armrest seat and the support arm, at least one positioning bead assembly is provided on the armrest seat or the support arm, and at least one bead groove is provided on the support arm or the armrest seat. When the armrest seat rotates, a "tick" sound is emitted when the bead engages or disengages from the bead groove, providing tactile feedback.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model's locking pin locking mechanism is simple to operate and reliable in locking; the positioning ball assembly provides tactile and auditory feedback, enhancing the user experience; it has a simple structure, low manufacturing cost, and is easy to maintain.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-3As shown, an armrest position adjustment mechanism includes an armrest 1, an armrest base 2, and a support arm 3. The armrest base 2 is provided with a first rotating shaft 21, through which the armrest 1 is rotatably connected to the armrest base 2. The support arm 3 is provided with a second rotating shaft 31, through which the armrest base 2 is rotatably connected to the support arm 3. A locking structure is provided within the armrest base 2, comprising a locking pin 4 and at least one positioning hole 32 on the support arm 3. The locking pin 4 can be inserted into the positioning hole 32 to lock the armrest base 2 to the support arm 3. A spring 5 is also provided within the armrest base 2, which abuts against the locking pin 4 to keep it inserted into the positioning hole 32.

[0019] The locking pin 4 is provided with an unlocking lever 41. By moving the unlocking lever 41, the locking pin 4 can overcome the elastic force of the spring 5 and disengage from the positioning hole 32.

[0020] The locking pin 4 is provided with a positioning ball assembly 6, which includes a ball 61 and a ball spring 62; the armrest seat 2 is provided with a ball groove 22 that cooperates with the ball 61; when the locking pin 4 is inserted into the positioning hole 32, the ball 61 is engaged in the ball groove 22 under the action of the ball spring 62; when the ball 61 is engaged or disengaged from the ball groove 22, a "tick" sound is emitted.

[0021] The support arm 3 is provided with four positioning holes 32, and the angular interval between adjacent positioning holes 32 is 90°.

[0022] The end of the locking pin 4 is tapered, which facilitates insertion into the positioning hole 32.

[0023] At the joint surface between the armrest seat 2 and the support arm 3, at least one positioning bead assembly is provided on the armrest seat 2 or the support arm 3, and at least one bead groove is provided on the support arm 3 or the armrest seat 2. When the armrest seat 2 rotates, a "tick" sound is emitted when the bead is engaged or disengaged from the bead groove, providing tactile feedback.

[0024] Operating Procedure: During use, by moving the unlocking lever 41, the locking pin 4 overcomes the spring force of the spring 5 and disengages from the positioning socket 32. Rotate the armrest base 2 until the locking pin 4 reaches the next positioning socket 32. Under the action of the spring 5, the locking pin 4 automatically inserts into the next positioning socket 32 ​​to complete the locking. Simultaneously, the retaining bead 61 re-engages into the retaining bead groove 22, emitting a "tick" sound, providing tactile and auditory feedback.

[0025] Meanwhile, when the armrest seat 2 is rotated, a "tick" sound is emitted at the joint surface between the armrest seat 2 and the support arm 3 because a positioning bead assembly is provided. When the bead is engaged or disengaged from the bead groove, it provides tactile and auditory feedback.

[0026] In summary, the handrail position adjustment mechanism of this utility model provides an innovative solution with broad market application prospects.

[0027] It should be noted that the parts not covered by this utility model are the same as or can be implemented using existing technology.
