Description

Technical Field

[0001] This utility model relates to the field of mobile phone stand technology, and in particular to a stand assembly. Background Technology

[0002] With the widespread use of electronic devices, phone holders are increasingly used in driving scenarios. Current technology typically employs a clamping structure to secure the electronic device and a locking mechanism to prevent it from falling off due to bumps. A typical phone holder includes two housings, a limiting structure between them, and a locking structure. The limiting structure primarily controls the phone's position, while the locking structure consists of a self-locking component and an auxiliary gear. After clamping the phone, the user presses the self-locking component, engaging its meshing end with the auxiliary gear, thus locking the limiting structure in place and preventing loosening. To save costs, the locking structure is usually located between the two housings and rotatably connected to a rotating shaft extending from the housings. However, during the assembly process of the phone holder, aligning the locking structure with the rotating shaft during installation of the two housings is difficult, making the assembly process inconvenient. Utility Model Content

[0004] The present invention provides a support assembly that solves the technical problem by including at least two movably connected housing structures, an elastic element, and a locking structure. The elastic element is sandwiched between the two housing structures. One housing structure has a rotating groove, and the other housing structure has a limiting structure. The locking structure includes a positioning assembly cover, an auxiliary gear, and a self-locking element.

The other end of the self-locking member is an open end, and the locking end or the open end is exposed outside the first clamping housing.

[0008] Preferably, the self-locking component has a positioning hole corresponding to the first rotating shaft, and the first rotating shaft passes through the positioning hole and is rotatably connected to the first rotating groove; When the locking end is subjected to force and rotates into the rotating groove, the locking teeth engage with the auxiliary gear, the limiting structure performs self-locking, and the open end is exposed outside the first clamping housing; when the open end is subjected to force and rotates into the rotating groove, the locking teeth and the auxiliary gear disengage, the limiting structure cancels self-locking, and the locking end is exposed outside the first clamping housing.

[0009] Preferably, a protrusion is provided on the side of the locking end away from the open end, and the two ends of the positioning assembly cover extend toward the bottom of the rotating groove to form a snap-fit ​​cover. The snap-fit ​​cover is provided with an adjacent first limiting groove and a second limiting groove on the side of the locking end corresponding to the protrusion. A limiting protrusion extends toward the locking end between the first limiting groove and the second limiting groove. When the locking end is subjected to force and rotates into the rotating groove, the protrusion slides from the first limiting groove to the second limiting groove through the limiting protrusion.

The bottom of the first locking groove and the second locking groove are provided with anti-slip strips.

[0014] Compared with the prior art, the support assembly provided by this utility model has the following advantages: 1. This utility model provides a bracket assembly, which includes at least two movably connected shell structures, an elastic element, and a locking structure. The elastic element is sandwiched between the two shell structures. One shell structure has a rotating groove, and the other shell structure has a limiting structure. The locking structure includes a positioning assembly cover, an auxiliary gear, and a self-locking component. The self-locking component and the auxiliary gear are disposed in the rotating groove and rotatably connected to the positioning assembly cover, with at least a portion of the self-locking component exposed outside the shell structure. One end of the auxiliary gear meshes with the other shell structure. When the self-locking component meshes with the auxiliary gear, the limiting structure self-locks. In this embodiment, the positioning assembly cover, as a locking structure, effectively solves the problem of inconvenient alignment between the locking structure and the shell rotation axis during traditional bracket assembly. The positioning assembly cover, as an independent pre-installed module, integrates and rotatably connects the self-locking component and the auxiliary gear inside, forming an integrated locking unit. During assembly, the entire locking unit is simply placed within a rotating slot in a housing structure and fixedly connected to the housing via a positioning mounting cover. This completes the installation of the self-locking component and auxiliary gears, eliminating the need to align each rotating shaft on the housing individually. This modular design significantly simplifies the assembly process, reduces operational complexity, and improves production efficiency during assembly.

[0015] 2. The housing structure of this utility model embodiment includes a first clamping housing, a second clamping housing, and a protective cover. The first clamping housing has a receiving groove for accommodating the second clamping housing, and one end of the first clamping housing has a clearance opening, while the other end extends to form a fixing portion. The elastic element is disposed within the receiving groove near the fixing portion. One end of the second clamping housing is connected to the elastic element, and the other end extends through the clearance opening corresponding to the fixing portion to form a clamping portion. The protective cover is disposed on the side of the second clamping housing away from the first clamping housing and is connected to the first clamping housing. A rotating groove communicating with the receiving groove is provided on the same side of the first clamping housing where the receiving groove is located. During assembly, it is only necessary to connect the second clamping housing through the clearance opening to the elastic element, and then place the protective cover over the receiving groove and connect it to the first clamping housing to complete the assembly of the bracket assembly, significantly reducing operation steps and alignment time.

[0016] 3. The positioning assembly cover of this utility model embodiment includes a cover body, a first rotating shaft, and a second rotating shaft. A first rotating groove is formed corresponding to the first rotating shaft, and a second rotating groove is formed corresponding to the second rotating shaft. The cover body covers the rotating grooves. The first rotating shaft passes through the self-locking component and is rotatably connected to the first rotating groove. The second rotating shaft passes through the auxiliary gear and is rotatably connected to the second rotating groove. Through the pre-positioning cooperation of the rotating shafts and rotating grooves, the tedious steps of aligning the self-locking component and auxiliary gear with the rotating shaft of the housing are eliminated, significantly reducing assembly complexity.

[0017] 4. In this embodiment of the invention, the end of the self-locking component near the auxiliary gear is a locking end, which has a locking tooth that cooperates with the auxiliary gear. The other end of the self-locking component is an open end, and either the locking end or the open end is exposed outside the first clamping housing. Users can switch states by directly pressing with their fingers. This intuitive operation allows for one-handed operation; users only need to press the exposed end with their thumb or forefinger to lock or unlock, and the entire process is smooth and natural.

[0018] 5. In this embodiment of the utility model, the self-locking component has a positioning hole corresponding to the first rotating shaft. The first rotating shaft passes through the positioning hole and is rotatably connected to the first rotating groove. When the locking end is subjected to force and rotates into the rotating groove, the locking teeth engage with the auxiliary gear, the limiting structure performs self-locking, and the open end is exposed outside the first clamping housing. When the open end is subjected to force and rotates into the rotating groove, the locking teeth and the auxiliary gear disengage, the limiting structure cancels self-locking, and the locking end is exposed outside the first clamping housing. Visualized status feedback allows users to quickly confirm the operation result, avoiding repeated operations or misjudgments caused by unclear status.

[0019] 6. In this embodiment of the invention, a protrusion is provided on the side of the locking end away from the open end. The two ends of the positioning assembly cover extend towards the bottom of the rotating groove to form a snap-fit ​​cover. On the side of the snap-fit ​​cover near the locking end, adjacent first and second limiting grooves are provided corresponding to the protrusion. A limiting protrusion extends towards the locking end between the first and second limiting grooves. When the locking end is subjected to force and rotates into the rotating groove, the protrusion slides from the first limiting groove to the second limiting groove via the limiting protrusion. The limiting protrusion serves as the critical point for the protrusion to switch between the two limiting grooves, providing clear tactile feedback to the user. When the locking end is subjected to force and rotates into the rotating groove, the protrusion slides from the first limiting groove to the second limiting groove via the limiting protrusion, allowing the user to clearly perceive the completion of the state switch through touch.

[0020] 7. In this embodiment of the invention, the locking end or the open end exposed on the surface of the first clamping housing is provided with anti-slip protrusions. This effectively solves the problem of finger slippage during operation.

[0021] 8. The elastic element in this embodiment of the utility model includes at least one spring. A first fixing post is provided in the receiving groove near the fixing part. A movable groove is opened at the end of the second clamping housing near the bottom of the receiving groove corresponding to the spring. A second fixing post is provided in the movable groove. One end of the spring is connected to the first fixing post, and the other end is connected to the second fixing post. The two fixing post structures form a clear connection path, so that the spring always moves in a predetermined direction during the stretching and rebounding process, avoiding the risk of lateral displacement or disengagement.

[0022] 9. The limiting structure in this embodiment of the present invention is a connecting rack. The connecting rack is disposed on the side of the second clamping housing near the rotating groove, and at least a portion of the auxiliary gear passes through the rotating groove and meshes with the connecting rack. During the clamping of the electronic device, the multi-tooth meshing of the connecting rack and the auxiliary gear ensures the smoothness of the transmission process and avoids the slippage or offset that may occur in traditional point contact transmission.

[0023] 10. In this embodiment of the invention, the fixing part is recessed in the axial direction of the clearance opening to form a first clamping groove, and the clamping part is recessed in the first clamping groove to form a second clamping groove. Anti-slip strips are provided at the bottom of the first and second clamping grooves. When the electronic device is clamped, its edge is embedded in the corresponding clamping groove, and the groove walls constrain the electronic device from multiple directions, preventing the electronic device from moving horizontally.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0034] It should be noted that the terms "first" and "second" in the specification and claims of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0039] With the widespread use of electronic devices, phone holders are increasingly used in driving scenarios. Current technology typically employs a clamping structure to secure the electronic device and a locking mechanism to prevent it from falling off due to bumps. A typical phone holder includes two housings, a limiting structure between them, and a locking structure. The limiting structure primarily controls the phone's position, while the locking structure consists of a self-locking component and an auxiliary gear. After clamping the phone, the user presses the self-locking component, engaging its meshing end with the auxiliary gear, thus locking the limiting structure in place and preventing loosening. To save costs, the locking structure is usually located between the two housings and rotatably connected to a rotating shaft extending from the housings. However, during the assembly process of the phone holder, aligning the locking structure with the rotating shaft during installation of the two housings is difficult, making the assembly process inconvenient.

[0040] Please combine Figure 1 , Figure 2 and Figure 3 This utility model provides a support assembly 10, which includes at least two movably connected housing structures 1, an elastic element 2, and a locking structure 3. The elastic element 2 is sandwiched between the two housing structures 1. One housing structure 1 has a rotating groove 11, and the other housing structure 1 has a limiting structure 12. The locking structure 3 includes a positioning assembly cover 31, an auxiliary gear 32, and a self-locking element 33. The self-locking element 33 and the auxiliary gear 32 are disposed in the rotating groove 11 and are rotatably connected to the positioning assembly cover 31, respectively. At least part of the self-locking element 33 is exposed outside the housing structure 1. One end of the auxiliary gear 32 meshes with the other housing structure 1. When the self-locking element 33 meshes with the auxiliary gear 32, the limiting structure 12 performs self-locking.

[0041] Understandably, the positioning assembly cover 31 in this embodiment, as the locking structure 3, effectively solves the problem of inconvenient alignment between the locking structure 3 and the rotating shaft of the housing during the assembly of traditional brackets. The positioning assembly cover 31, as an independent pre-assembled module, integrates and rotatably connects the self-locking component 33 and the auxiliary gear 32 within it, forming an integrated locking unit. During assembly, the entire locking unit is simply placed into the rotating groove 11 of the housing structure 1 and fixedly connected to the housing via the positioning assembly cover 31 to complete the installation of the self-locking component 33 and the auxiliary gear 32, eliminating the need to align them individually with the rotating shaft on the housing. This modular design significantly simplifies the assembly process, reduces operational complexity, and improves production efficiency during assembly.

[0042] Furthermore, the positioning assembly cover 31 not only serves as a connection and support but also ensures the stable movement of the self-locking component 33 and the auxiliary gear 32 within the rotating groove 11. Since both the self-locking component 33 and the auxiliary gear 32 are rotatably connected to the positioning assembly cover 31, their relative positions and movement trajectories are precisely constrained, avoiding poor meshing caused by component misalignment or loosening during assembly. When closing the two housing structures 1, the worker only needs to place the pre-assembled locking unit into the rotating groove 11 and then fix the positioning assembly cover 31, without repeatedly adjusting the alignment angle between the self-locking component 33 or the auxiliary gear 32 and the housing rotation axis. This reduces assembly time and lowers the risk of component damage due to misoperation.

[0043] Furthermore, the design of the positioning assembly cover 31 enhances the overall rigidity and durability of the locking structure 3. The self-locking component 33 is partially exposed on the housing structure 1, allowing the user to switch the self-locking state via a pressing operation. The auxiliary gear 32 engages with the limiting structure 12 of another housing structure 1, achieving mechanical self-locking. Because the positioning assembly cover 31 provides a stable pivot point, the engagement between the self-locking component 33 and the auxiliary gear 32 is more precise and reliable, ensuring effective locking of the limiting structure 12 in bumpy environments and preventing electronic equipment from loosening or falling off due to vibration. Simultaneously, this modular structure facilitates maintenance and replacement. If the locking component is damaged, the positioning assembly cover 31 can be disassembled separately for maintenance without disassembling the entire bracket assembly 10, improving the product's maintainability and service life.

[0044] It should be understood that this embodiment achieves rapid assembly and stable operation of the locking structure 3 through the modular integration of the positioning assembly cover 31, which not only improves production efficiency and assembly accuracy, but also ensures the reliability of the bracket in dynamic environments.

[0045] Furthermore, please combine them together. Figure 3The housing structure 1 includes a first clamping housing 13, a second clamping housing 14, and a protective cover 15. The first clamping housing 13 has a receiving groove 16 for accommodating the second clamping housing 14. One end of the first clamping housing 13 has a clearance opening 17, and the other end extends to form a fixing part 18. An elastic member 2 is disposed within the receiving groove 16 near the fixing part 18. One end of the second clamping housing 14 is connected to the elastic member 2, and the other end extends through the clearance opening 17 corresponding to the fixing part 18 to form a clamping part 19. The protective cover 15 is disposed on the side of the second clamping housing 14 away from the first clamping housing 13 and is connected to the first clamping housing 13. A rotating groove 11 communicating with the receiving groove 16 is provided on the same side of the first clamping housing 13. The fixing part 18 and the clamping part 19 are disposed opposite to each other and, together with the protective cover 15, define a clamping space. The electronic device can be accommodated within the clamping space. It should be noted that the area of ​​the positioning assembly cover 31 is smaller than that of the protective cover 15, which allows the smaller positioning assembly cover 31 to complete the assembly work more quickly.

[0046] Specifically, the clearance opening 17 at one end of the first clamping housing 13 allows one end of the second clamping housing 14 to extend out to form a clamping part 19, and the fixing part 18 at the other end can cooperate with the clamping part 19 to clamp the electronic device. The elastic member 2 is disposed in the receiving groove 16 near the fixing part 18. During assembly, the second clamping housing 14 is simply passed through the clearance opening 17 and connected to the elastic member 2, and then the protective cover 15 is placed on top of the receiving groove 16 and connected to the first clamping housing 13 to complete the assembly of the bracket assembly 10, which greatly reduces the operation steps and alignment time. In addition to accommodating the second clamping housing 14, the receiving groove 16 can also limit the second clamping housing 14, forcing the second clamping housing 14 to move relative to the first clamping housing 13 in the axial direction of the clearance opening 17.

[0047] Furthermore, the protective cover 15 enhances the overall integrity and protection of the structure. The protective cover 15 covers the side of the second clamping housing 14 away from the first clamping housing 13 and connects to the first clamping housing 13. It not only provides encapsulation, preventing dust or foreign objects from entering the receiving groove 16 and affecting the internal mechanism, but also strengthens the connection strength between the first clamping housing 13 and the second clamping housing 14 by increasing the connection point. This design ensures that the second clamping housing 14 will not detach or loosen from the receiving groove 16 under vibration or bumpy conditions, maintaining the stability of the clamping force. In addition, the rotating groove 11 is located on the same side as the receiving groove 16. In one embodiment, the protective cover 15 is not placed on the positioning assembly cover 31, allowing the installation of the locking structure 3 to be performed simultaneously with the housing assembly, reducing assembly complexity. In another embodiment, the protective cover 15 is placed on the positioning assembly cover 31, and the protective cover 15 and the positioning assembly cover 31 provide dual protection for the auxiliary gear 32 and the self-locking component 33 inside the locking structure 3.

[0048] Furthermore, please combine Figure 2 , Figure 3 and Figure 4 The positioning assembly cover 31 includes a cover body 311, a first rotating shaft 312 and a second rotating shaft 313. The rotating groove 11 is provided with a first rotating groove 111 corresponding to the first rotating shaft 312, and the rotating groove 11 is provided with a second rotating groove 112 corresponding to the second rotating shaft 313. The cover body 311 covers the rotating groove 11. The first rotating shaft 312 passes through the self-locking member 33 and is rotatably connected to the first rotating groove 111. The second rotating shaft 313 passes through the auxiliary gear 32 and is rotatably connected to the second rotating groove 112.

[0049] Understandably, in this embodiment, the positioning assembly cover 31 fixes the first rotating shaft 312 and the second rotating shaft 313 to the cover body 311. During assembly, simply insert the self-locking member 33 through the first rotating shaft 312 and the auxiliary gear 32 through the second rotating shaft 313, and then cover the entire positioning assembly cover 31 onto the rotating groove 11, so that the first rotating shaft 312 aligns with the first rotating groove 111 and the second rotating shaft 313 aligns with the second rotating groove 112, thus completing the connection between the locking structure 3 and the housing. Through the pre-positioning cooperation of the rotating shaft and the rotating groove, the tedious steps of aligning the self-locking member 33 and the auxiliary gear 32 with the rotating shaft of the housing one by one are eliminated, greatly reducing the assembly complexity. For example, in the production line, workers can pre-install the self-locking member 33 and the auxiliary gear 32 onto the positioning assembly cover 31 to form a sub-assembly, and then insert the whole assembly into the rotating groove 11. The guiding effect of the rotating shaft and the rotating groove ensures the accuracy of alignment and avoids misalignment problems caused by visual errors or manual adjustments, thereby improving assembly efficiency.

[0050] Furthermore, the cover 311 enhances the sealing and protection of the rotating groove 11 by concealing it. The cover 311 not only serves as a fixed base for the rotating shaft but also seals the opening of the rotating groove 11, preventing dust, moisture, and other foreign matter from entering and affecting the movement of the self-locking component 33 and the auxiliary gear 32. Simultaneously, the rotational connection between the first rotating shaft 312 and the first rotating groove 111, and between the second rotating shaft 313 and the second rotating groove 112, provides a stable rotational fulcrum, ensuring that the self-locking component 33 and the auxiliary gear 32 can rotate smoothly under force without shifting or falling off. Moreover, because the rotational centers of the self-locking component 33 and the auxiliary gear 32 are precisely constrained, their meshing is more reliable, allowing the user to smoothly switch between self-locking and unlocking states when operating the self-locking component 33, avoiding the risk of jamming.

[0051] Furthermore, please combine them together. Figure 5The self-locking member 33 has a locking end 331 at one end near the auxiliary gear 32. The locking end 331 is provided with a locking tooth 332 that cooperates with the auxiliary gear 32. The other end of the self-locking member 33 is an open end 333. The locking end 331 or the open end 333 is exposed outside the first clamping housing 13.

[0052] It is understood that the self-locking member 33 in this embodiment has a locking end 331 and an open end 333, and a locking tooth 332 that precisely engages with the auxiliary gear 32 is provided on the locking end 331. Specifically, the locking end 331 and the auxiliary gear 32 form a mechanical engagement, and the locking tooth 332 thereon can contact the tooth groove of the auxiliary gear 32, ensuring that it will not accidentally disengage even if subjected to vibration or external impact in the engaged state.

[0053] Furthermore, the exposed portion of either the locking end 331 or the open end 333 allows the user to switch states by directly pressing with their finger. This intuitive operation allows for one-handed operation; the user only needs to press the exposed end with their thumb or forefinger to lock or unlock, making the entire process smooth and natural. When the user needs to pick up or put down the phone, simply pressing the exposed open end 333 will unlock it; and when the electronic device is placed in position, pressing the locking end 331 will securely lock it, making it simple and convenient.

[0054] Furthermore, please combine Figure 3 , Figure 4 and Figure 5 The self-locking component 33 has a positioning hole 334 corresponding to the first rotating shaft 312, and the first rotating shaft 312 passes through the positioning hole 334 and is rotatably connected to the first rotating groove 111. When the locking end 331 is subjected to force and rotates into the rotating groove 11, the locking tooth 332 engages with the auxiliary gear 32, the limiting structure 12 performs self-locking, and the open end 333 is exposed to the first clamping housing 13; when the open end 333 is subjected to force and rotates into the rotating groove 11, the locking tooth 332 and the auxiliary gear 32 disengage, the limiting structure 12 cancels self-locking, and the locking end 331 is exposed to the first clamping housing 13.

[0055] Understandably, the cooperation between the positioning hole 334 and the first rotating shaft 312 in this embodiment provides a stable rotation center for the self-locking member 33, ensuring that the self-locking member 33 always maintains a predetermined movement trajectory during rotation. When the locking end 331 is forced to rotate into the rotating groove 11, the self-locking member 33 rotates smoothly around the first rotating shaft 312, and the locking teeth 332 and the auxiliary gear 32 achieve precise engagement. At this time, the open end 333 is naturally exposed in the first clamping housing 13, forming a clear indication of the locking completion status. Furthermore, when unlocking is required, the user only needs to press the exposed open end 333, and the self-locking member 33 rotates in the opposite direction around the first rotating shaft 312. The locking teeth 332 and the auxiliary gear 32 smoothly disengage, and the locking end 331 is automatically exposed, clearly indicating that the unlocking state has been entered. This visual status feedback allows the user to quickly confirm the operation result, avoiding repeated operations or misjudgments caused by unclear status.

[0056] Furthermore, a protrusion 335 is provided on the side of the locking end 331 away from the open end 333. The two ends of the positioning assembly cover 31 extend toward the bottom of the rotating groove 11 to form a snap-fit ​​cover 314. On the side of the snap-fit ​​cover 314 near the locking end 331, a first limiting groove 315 and a second limiting groove 316 are provided corresponding to the protrusion 335. A limiting protrusion 317 extends toward the locking end 331 between the first limiting groove 315 and the second limiting groove 316. When the locking end 331 is subjected to force and rotates into the rotating groove 11, the protrusion 335 slides from the first limiting groove 315 to the second limiting groove 316 through the limiting protrusion 317.

[0057] Understandably, in this embodiment, the protrusion 335 on the locking end 331 forms a snap-fit ​​relationship with the adjacent first limiting groove 315 and second limiting groove 316 on the snap-fit ​​cover 314. The limiting protrusion 317 serves as the critical point for the protrusion 335 to slide into the two limiting grooves, providing clear tactile feedback to the user. When the locking end 331 is rotated into the rotating groove 11 under force, the protrusion 335 slides from the first limiting groove 315 through the limiting protrusion 317 to the second limiting groove 316. During the sliding process, the user can feel a distinct "click" when the protrusion 335 passes through the limiting protrusion 317, clearly perceiving the completion of the state switch through tactile feedback, eliminating the uncertainty of the state position, and ensuring that each operation accurately reaches the predetermined position.

[0058] Furthermore, when the protrusion 335 is located in the first limiting groove 315, it corresponds to the unlocked state. At this time, the limiting protrusion 317 and the groove wall together constrain the position of the protrusion 335 to prevent accidental sliding caused by vibration of the electronic device. When the protrusion 335 crosses the limiting protrusion 317 and enters the second limiting groove 316, it corresponds to the locked state. The groove wall limits the protrusion 335, and it will not fall out of position even if subjected to continuous vibration.

[0059] Furthermore, the locking end 331 or the open end 333 exposed on the surface of the first clamping housing 13 is provided with anti-slip protrusions 336. Specifically, this embodiment effectively solves the problem of finger slippage during operation by providing anti-slip protrusions 336 on the exposed surface of the self-locking member 33. The anti-slip protrusions 336 significantly increase the friction between the finger and the operating surface, so that even when the user's fingers are wet, oily, or wearing gloves, a stable and reliable operating feel can be obtained.

[0060] Furthermore, please combine Figure 2 and Figure 6 The elastic element 2 includes at least one spring. A first fixing post 161 is provided on one side of the receiving groove 16 near the fixing part 18. A movable groove 141 is opened at one end of the second clamping housing 14 near the bottom of the receiving groove 16 corresponding to the spring. A second fixing post 142 is provided in the movable groove 141. One end of the spring is connected to the first fixing post 161 and the other end is connected to the second fixing post 142.

[0061] Understandably, in this embodiment, the first fixing post 161 is disposed within the receiving groove 16 near the fixing part 18, providing a stable foundation support for the spring; the second fixing post 142 is integrated into the movable groove 141 of the second clamping housing 14 and connected to the other end of the spring. The two fixing post structures form a clear connection path, ensuring that the spring always moves in a predetermined direction during stretching and rebound, avoiding the risk of lateral displacement or disengagement. Furthermore, the second fixing post 142 is embedded in the movable groove 141, and its position is naturally aligned with the movement trajectory of the second clamping housing 14, reducing assembly errors. Furthermore, the limiting structure 12 is a connecting rack 121, and the connecting rack 121 is disposed on the side of the second clamping housing 14 near the rotating groove 11, with at least a portion of the auxiliary gear 32 passing through the rotating groove 11 and meshing with the connecting rack 121. It should be noted that the number of springs corresponds to the number of movable grooves 141.

[0062] Understandably, in this embodiment, the limiting structure 12 is a connecting rack 121, which is positioned on the side of the second clamping housing 14 near the rotating groove 11. Simultaneously, the auxiliary gear 32 passes through the rotating groove 11 and directly meshes with the connecting rack 121, effectively solving the problems of low efficiency and slippage in traditional transmission methods. The meshing transmission mechanism of the rack and gear provides a continuous and stable power transmission path. When the user pulls down the clamping part 19, the force is precisely transmitted to the auxiliary gear 32 through the connecting rack 121. After the clamping part 19 is pulled down to a suitable length, the electronic device can be placed between the clamping part 19 and the fixing part 18. Releasing the pull on the clamping part 19 causes the spring to provide a restoring force, which forces the clamping part 19 to retract into the receiving groove 16, clamping the electronic device. At this time, the user presses down the self-locking member 33 to lock the second clamping housing 14. It should be understood that during the clamping of electronic devices, the multi-tooth meshing of the connecting rack 121 and the auxiliary gear 32 ensures the smoothness of the transmission process, avoids the slippage or offset that may occur in traditional point contact transmission, and makes the application of clamping force more uniform and controllable.

[0063] Furthermore, please combine Figure 2 , Figure 6 and Figure 7 The fixing part 18 is recessed in the axial direction of the clearance opening 17 to form a first clamping groove 20, and the clamping part 19 is recessed in the first clamping groove 20 to form a second clamping groove 22. Anti-slip strips 23 are provided at the bottom of the first clamping groove 20 and the second clamping groove 22.

[0064] Understandably, this embodiment effectively solves the problem of electronic devices easily slipping out when clamped by providing a first clamping groove 20 and a second clamping groove 22 in the fixing part 18 and the clamping part 19 respectively, and providing an anti-slip strip 23 at the bottom of the groove. The first clamping groove 20 is formed in the axial recess of the fixing part 18 facing the clearance opening 17, and the second clamping groove 22 is correspondingly formed in the clamping part 19. This symmetrical groove structure provides stable clamping for the electronic device. When the electronic device is clamped, its edge is embedded in the corresponding clamping groove, and the groove wall constrains the electronic device from multiple directions, preventing the electronic device from moving in the horizontal direction. Furthermore, the anti-slip strip 23 provided at the bottom of the groove greatly enhances the friction between the bracket assembly 10 and the surface of the electronic device.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
