Description

Technical Field

[0001] This utility model relates to the field of mobile phone holder technology, specifically to a vehicle-mounted mobile phone holder. Background Technology

[0002] With the development of mobile communication technology, smartphones are playing an increasingly important role in people's daily lives, especially in driving scenarios where phone navigation has become a necessity. Therefore, car phone holders have become a common accessory in car interiors. Existing car phone holders typically consist of a base for fixing the phone to the dashboard and a main body for holding the phone in place.

[0003] To meet the driver's need to adjust the viewing angle, some existing vehicle mounts are designed with a rotating structure. For example, Chinese Patent Publication No. CN221250950U discloses a wireless charging phone holder. According to the patent specification and drawings, it includes a fixed base and a back support structure connected to the fixed base. Regarding rotation adjustment, this prior art uses a structure where a panel and a lower shell support cooperate. The lower end face of the panel is fixedly provided with a second elastic structure and a fixing member, and the lower shell has multiple fixing positions for the fixing member to engage and fix, with all fixing positions distributed in a ring.

[0004] However, after practical use and in-depth research of the above-mentioned existing technologies, the following technical defects were found:

[0005] Limited Rotation Angle and Positioning Experience: Although the comparative document CN221250950U mentions a ring-shaped distribution of fixed positions, its instruction manual further clarifies that "two tracks of the fixed positions are symmetrically arranged on the lower shell," and "the length of all the fixed positions is 1 / 6 of the circumference of the current ring, corresponding to a panel rotation angle of 60°." This means that the rotation of this prior art is not a true full-circumferential unlimited rotation, but a segmented rotation limited by the length of the track. When the driver needs to significantly adjust the orientation of the phone (e.g., rotate it 180 degrees for the passenger to see, or make a large-scale switch between portrait and landscape modes), the structure cannot rotate due to the limitation of the end point of the track. In addition, relying on a simple elastic structure and fixed position engagement, it is prone to jamming or blurred positioning feel after long-term rotational friction.

[0006] Insufficient stability and quality of the base: Existing mounting bases are usually assembled from an upper and lower shell, mainly relying on adhesive silicone on the lower end for fixation. This pure plastic shell is lightweight, resulting in a high center of gravity for the entire bracket. When the vehicle experiences severe bumps, the lightweight base is prone to resonance or wobbling, affecting the viewing experience, and lacks a high-end damping feel.

[0007] Complexity of the clamping structure: The clamping structure in the comparison document requires the support assembly to move and compress the internal elastic structure, which is relatively complicated.

[0008] Therefore, there is a need for a vehicle mount with a robust structure that can achieve 360-degree positioning and rotation, and a clamping operation silicone base. Utility Model Content

[0009] In order to overcome the technical defects of existing vehicle mounts that are limited in rotation angle and cannot achieve 360-degree full circumferential positioning, this utility model provides a vehicle mount phone holder.

[0010] To solve the above problems, this utility model is implemented according to the following technical solution:

[0011] The vehicle-mounted mobile phone holder of this utility model includes:

[0012] A base assembly having an inwardly recessed receiving cavity, the inner wall of which is provided with a toothed ring member, and the upper surface of the toothed ring member having a plurality of positioning tooth grooves evenly distributed along the circumferential direction.

[0013] A rotating seat is disposed on the receiving cavity of the base assembly, and an elastic abutting mechanism is provided at the bottom of the rotating seat, which engages with the positioning tooth groove;

[0014] When the rotating seat rotates, the elastic abutting mechanism slides on the gear ring and sequentially engages in different positioning tooth grooves to achieve circumferential positioning of the rotating seat relative to the base assembly.

[0015] A support assembly is disposed on top of the rotating base, and the support assembly includes a support back plate for supporting the mobile phone.

[0016] Furthermore, the rotating base includes a base and a base panel. The base panel is provided with a C-shaped fixing bracket and has a mounting groove that is adapted to the C-shaped fixing bracket, so that the C-shaped fixing bracket can be detachably connected to the rotating base.

[0017] Furthermore, the bottom of the rotating base is provided with a sliding mounting seat, and the base panel is provided with several sliding grooves. The bottom of the bracket assembly passes through the sliding grooves and is connected to the sliding mounting seat, so that the bracket assembly can reciprocate relative to the C-shaped fixing frame along the long axis of the sliding groove to clamp or release the mobile phone.

[0018] Furthermore, the side wall of the sliding mounting base is provided with a positioning post, and an elastic reset member is sleeved on the positioning post. One end of the elastic reset member abuts against the positioning post, and the other end of the elastic reset member abuts against the inner side wall of the rotating base.

[0019] When the bracket assembly is opened by an external force, the bracket assembly moves along the slide groove and compresses the elastic reset member to release the mobile phone;

[0020] When the external force disappears, the elastic reset member drives the bracket assembly to reset and clamp, and cooperates with the C-shaped fixing frame to hold the mobile phone.

[0021] Furthermore, the elastic abutment mechanism includes a receiving groove, a spring, and a guide member;

[0022] The receiving groove is formed on the bottom surface of the rotating base, the spring is placed in the receiving groove, one end of the guide is engaged with the spring, the other end of the guide is adapted to the positioning tooth groove, and the guide abuts against the positioning tooth groove under the elastic force of the spring.

[0023] Furthermore, the base assembly includes a support shell and a flexible silicone layer covering the outer surface of the support shell;

[0024] The support shell has a counterweight inside, which is connected to the support shell by screws.

[0025] Furthermore, the front surface of the support back plate is recessed to form a receiving groove, and an anti-slip pad is embedded in the receiving groove. The surface of the anti-slip pad is provided with an anti-slip texture.

[0026] Furthermore, an adhesive layer is adhered to the bottom plane of the base assembly, which is used to adsorb and fix the base assembly to the bearing surface.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] This utility model discloses a car phone holder. By incorporating a fixedly connected gear ring within the receiving cavity of the base assembly, with positioning grooves evenly distributed circumferentially, and in conjunction with an elastic abutment mechanism at the bottom of the rotating body, the user can drive the rotating body to rotate 360 ​​degrees relative to the base assembly according to actual needs, satisfying the viewing angle requirements of the driver, passenger, and others. Utilizing the elastic engagement between the elastic abutment mechanism and the positioning grooves, when the rotating body stops rotating, the elastic element presses the abutment component into the groove, forming a locking state. This structure overcomes the bumps and vibrations generated during vehicle operation, preventing the rotating body from unexpectedly shifting due to inertia or vibration, ensuring a stable phone support viewing angle. When the rotating body rotates, the elastic abutment mechanism slides on the gear ring and sequentially engages with different positioning grooves. Compared to traditional stepless friction rotation, this graded positioning structure not only provides a smoother adjustment feel and clearer positioning feedback, but also, due to the compensating effect of the elastic mechanism, is less prone to loosening or failure after long-term use, extending the product's lifespan.

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] like Figures 1-3 As shown, the vehicle-mounted mobile phone holder of this utility model includes:

[0038] The base assembly 10 has an inwardly recessed receiving cavity 11. A toothed ring member 12 is fixedly connected to the inner wall of the receiving cavity 11. A plurality of positioning tooth grooves 13 are evenly distributed along the circumferential direction on the upper surface of the toothed ring member 12.

[0039] The rotating seat 20 is located on the receiving cavity 11 of the base assembly 10. The bottom of the rotating seat 20 is provided with an elastic abutment mechanism 21, which engages with the positioning tooth groove 13. When the rotating seat 20 rotates, the elastic abutment mechanism 21 slides on the toothed ring 12 and sequentially engages with different positioning tooth grooves 13 to achieve circumferential positioning of the rotating seat 20 relative to the base assembly 10.

[0040] The bracket assembly 30 is located on top of the rotating base 20 and includes a support back plate 31 for supporting the mobile phone.

[0041] This embodiment provides a vehicle-mounted mobile phone holder, which is mainly composed of three parts: a base assembly 10, a rotating seat 20, and a bracket assembly 30.

[0042] Regarding the structure of the base assembly 10: The base assembly 10 serves as the mounting base for the entire bracket, and its main body has an inwardly recessed receiving cavity 11. The receiving cavity 11 is used to support the rotating seat 20. A gear ring member 12 is fixedly connected to the inner wall of the receiving cavity 11 (e.g., on the annular stepped surface at the bottom of the receiving cavity). Several positioning grooves 13 are evenly distributed along the circumference on the upper surface of the gear ring member 12. These positioning grooves 13 are connected end to end and arranged along the circumference to form a positioning track.

[0043] In this embodiment, it should be noted that the gear ring 12 is fixed on the bottom plane of the receiving cavity 11 of the base assembly 10. The positioning groove 13 is not a simple perforation, but a continuous undulating wave-like or sawtooth structure formed on the upper surface of the gear ring 12.

[0044] The positioning grooves 13 are radially and evenly distributed along the circumference of the gear ring 12, forming a circular track. Specifically, each positioning groove 13 consists of guide slopes on both sides and a recess at the bottom. A tooth ridge (i.e., a crest) is formed between two adjacent positioning grooves 13. From a side cross-section, multiple positioning grooves 13 form a continuous "V" or "U" shaped wave cross-section. The width and depth of the positioning grooves 13 are adapted to the diameter of the elastic abutment mechanism 21, allowing the elastic abutment mechanism 21 to be partially embedded in the recess.

[0045] If it were just a smooth surface, the bracket would easily rotate due to the shift in the center of gravity when the car is bumpy. By designing recessed positioning grooves 13, the elastic abutment mechanism 21 naturally rests at the bottom of the groove (the point of lowest potential energy). When there is no external force for rotation, the groove wall blocks the elastic abutment mechanism 21, generating a self-locking torque to ensure the stability of the phone's viewing angle. The circumferentially distributed design eliminates the limitations of the starting and ending points of rotation, allowing users to rotate infinitely in any direction.

[0046] In practical applications, the shape of the positioning groove 13 can be adjusted according to the required damping force:

[0047] 1. Strong locking type: The positioning tooth groove 13 is designed as a trapezoidal or rectangular groove. This design has a strong locking force and is not easy to rotate, but the rotation feels stiff and requires a large starting torque, and the elastic abutment mechanism 21 wears more.

[0048] 2. Silent and Smooth Type: The positioning groove 13 is designed with a shallow arc-shaped wave surface, resulting in minimal undulation. This design allows for smooth rotation and low noise, but its anti-vibration capability is relatively weak, making it suitable for desktop stands.

[0049] 3. Inner wall teeth: The positioning tooth groove 13 is not located on the upper surface, but on the inner cylindrical surface of the tooth ring component 12, and the elastic abutment mechanism 21 is horizontally set. This design can reduce the height of the base, but the assembly difficulty is slightly greater.

[0050] Considering the in-vehicle scenario in this case, the preferred design adopted in this embodiment is as follows:

[0051] Tooth profile selection: A deep U-shaped cross section is preferred, with rounded corners at the top of the tooth ridge.

[0052] The deep U-shape provides sufficient lateral support and strong resistance to bumps; the rounded corners of the toothed ridges allow for a smoother transition of the guide 213, preventing jamming or sharp noise.

[0053] Regarding the rotating base 20 and the rotating structure: The rotating base 20 is rotatably mounted on the receiving cavity 11 of the base assembly 10. To achieve the positioning function during rotation, an elastic abutment mechanism 21 is provided at the bottom of the rotating base 20. The position of the elastic abutment mechanism 21 corresponds to the gear ring member 12 on the base, and the lower end of the elastic abutment mechanism 21 extends downward and forms an elastic meshing engagement with the positioning tooth groove 13 on the gear ring member 12.

[0054] Regarding the bracket assembly 30: The bracket assembly 30 is disposed on top of the rotating base 20 and rotates together with the rotating base 20. The bracket assembly 30 includes a support back plate 31 for supporting the back of the mobile phone, which is connected to the rotating base 20 and is used to support the mobile terminal.

[0055] Working principle: When the user rotates the rotating seat 20, the rotating seat 20 drives the elastic abutting mechanism 21 at the bottom to move relative to the base assembly 10. The elastic abutting mechanism 21 slides on the surface of the gear ring 12 and overcomes the elastic resistance to slide out of the current positioning tooth groove 13. When rotating to the next angle, the elastic abutting mechanism 21, under the action of its own elastic force, sequentially engages into different positioning tooth grooves 13. This engagement method achieves circumferential positioning of the rotating seat 20 relative to the base assembly 10, allowing the bracket to be adjusted 360 degrees in all directions. When the rotation stops, the viewing angle can be stabilized by the elastic meshing force, preventing accidental rotation due to vehicle bumps.

[0056] Furthermore, the rotating base 20 includes a base 22 and a base panel 23. The base panel 23 is provided with a C-shaped fixing bracket 24 and has a mounting groove 231 that is adapted to the C-shaped fixing bracket 24, so that the C-shaped fixing bracket 24 can be detachably connected to the rotating base 20.

[0057] To facilitate the assembly and production of internal parts, the structure of the rotating base 20 has been optimized in this embodiment. The rotating base 20 is not a one-piece molded part, but an assembly formed by fastening or screwing together the base 22 (lower main body) and the base panel 23 (upper cover). This split structure provides a closed housing space for the internal mechanical transmission components.

[0058] Regarding the mounting structure of the C-type bracket 24: A mounting groove 231 is integrally injection molded on the surface of the base panel 23 (preferably the lower surface facing inward). The shape, depth, and outline dimensions of the mounting groove 231 are adapted to the C-type bracket 24. During assembly, the C-type bracket 24 is embedded into the mounting groove 231. Because the sidewalls of the mounting groove 231 enclose and limit the C-type bracket 24, it can prevent the C-type bracket 24 from displacing or shaking in the plane when subjected to force (such as the reaction force generated by clamping a mobile phone), thus ensuring the stability of the structure.

[0059] Regarding the detachable connection: To achieve a detachable connection, the C-type bracket 24 and the mounting slot 231 can be fitted together in the following manner:

[0060] Interference fit: The size of the mounting slot 231 is slightly smaller than that of the C-shaped bracket 24. It is fastened by pressing in and fixed by friction. It can also be pried out with a tool.

[0061] Snap-fit ​​connection: The mounting slot 231 is provided with barbs or locking points, and the C-shaped fixing bracket 24 is provided with corresponding locking slots. Pressing it will lock it in place.

[0062] Screw fixing: Although the C-type bracket 24 is mainly limited by the mounting slot 231, it can also be tightened by the screw passing through the base panel 23. When disassembling, simply unscrew the screw.

[0063] Furthermore, the bottom of the rotating base 20 is provided with a sliding mounting base 25, and the base panel 23 is provided with a plurality of sliding grooves 232. The bottom of the bracket assembly 30 passes through the sliding grooves 232 and is connected to the sliding mounting base 25, so that the bracket assembly 30 can reciprocate relative to the C-shaped fixing frame 24 along the long axis of the sliding grooves 232 to achieve clamping or releasing of the mobile phone.

[0064] like Figure 2 As shown, this embodiment has specifically designed the installation and movement of the bracket assembly 30 to achieve clamping operation.

[0065] Regarding the sliding connection structure: Inside the rotating base 20 (specifically located in the space below the base panel 23), a sliding mounting base 25 is provided. This sliding mounting base 25 is a movable slider component, designed to move linearly along a predetermined trajectory within the internal space of the rotating base 20. Several elongated grooves 232 are correspondingly formed on the base panel 23. The direction of the grooves 232 is consistent with the predetermined moving direction of the support assembly 30 (i.e., along the long axis of the groove).

[0066] Regarding the connection between the bracket assembly 30 and the interior: The bracket assembly 30 is located above the base panel 23. A connecting post 32 extends from the bottom of the bracket assembly 30. During assembly, the connecting post 32 at the bottom of the bracket assembly 30 passes vertically downward through the slide groove 232 on the base panel 23 and is fixedly connected to the sliding mounting base 25 located below the panel (it can be fixed by screws or clips).

[0067] Since the C-shaped mounting bracket 24 is fixed to the base panel 23 (serving as a stationary reference), while the sliding mounting base 25 and the bracket assembly 30 are not directly fixed to the panel but are limited by the slide groove 232, when the user manually moves the bracket assembly 30 outward, the bracket assembly 30 will cause the sliding mounting base 25 at the bottom to move together. At this time, the bracket assembly 30 reciprocates linearly along the long axis of the slide groove 232 relative to the fixed C-shaped mounting bracket 24. When the bracket assembly 30 is moved outward, the sliding mounting base 25 moves outward accordingly, increasing the distance between the bracket assembly 30 and the C-shaped mounting bracket 24 (i.e., opening up). The slide groove 232 restricts its linear trajectory of movement, preventing deflection. When reset by elastic restoring force, the sliding mounting base 25 causes the bracket assembly 30 to retract inward, thereby cooperating with the C-shaped mounting bracket 24 to clamp the phone.

[0068] Furthermore, the bent part of the C-shaped bracket 24 is also equipped with a soft anti-pinch part, which can be made of flexible silicone or sponge to prevent the C-shaped bracket 24 from causing wear and tear on the phone during the clamping process.

[0069] This design, which hides the sliding mechanism under the panel, not only makes the bracket look cleaner and simpler, avoiding the exposure of the mechanical structure, but also uses the slide groove 232 on the base panel 23 as a guide rail to improve the stability of the movement and prevent the bracket assembly 30 from shaking or getting stuck during movement.

[0070] Furthermore, the side wall of the sliding mounting base 25 is provided with a positioning post 251, and an elastic reset member 26 is sleeved on the positioning post 251. One end of the elastic reset member 26 abuts against the positioning post 251, and the other end of the elastic reset member 26 abuts against the inner side wall of the rotating base 20.

[0071] When the bracket assembly 30 is opened by an external force, the bracket assembly 30 moves along the slide groove 232 and compresses the elastic reset member 26 to release the mobile phone;

[0072] When the external force disappears, the elastic reset member 26 drives the bracket assembly 30 to reset and clamp, and cooperates with the C-type fixing bracket 24 to hold the mobile phone.

[0073] To achieve the automatic clamping function, a positioning post 251 is provided extending outward from the side wall of the sliding mounting base 25. This positioning post 251 serves as the mounting carrier for the elastic reset member 26, preventing the elastic reset member 26 from bending or falling off during compression or rebound.

[0074] In this embodiment, the elastic reset member 26 is preferably a helical spring. The helical spring is sleeved on the positioning post 251 and is located between the sliding mounting base 25 and the inner sidewall of the rotating base 20. Specifically, one end of the helical spring abuts against the root structure of the positioning post 251, and the other end abuts directly against the fixed sidewall structure inside the rotating base 20.

[0075] The working process is as follows: When the user needs to insert the phone, an external force is applied to push the bracket assembly 30 outward. The bracket assembly 30 drives the sliding mounting base 25 to move outward along the slide groove 232. During this process, the positioning post 251 on the sliding mounting base 25 moves accordingly, forcing the elastic reset member 26 to be gradually compressed between the positioning post 251 and the inner wall of the rotating seat 20, thereby accumulating elastic potential energy. The distance between the bracket assembly 30 and the C-shaped fixing bracket 24 increases, forming an opening space sufficient to accommodate the phone.

[0076] When the user places the phone in and removes the external force, the compressed elastic reset member 26 releases its elastic potential energy, generating a reverse thrust. This thrust acts on the positioning post 251, driving the sliding mounting base 25 and the bracket assembly 30 connected thereto to retract in the opposite direction along the slide groove 232. The bracket assembly 30 resets under the action of the elastic force, and, together with the fixed C-shaped fixing bracket 24, clamps the phone in the middle.

[0077] Furthermore, the elastic abutment mechanism 21 includes a receiving groove 211, a spring 212, and a guide member 213;

[0078] The receiving groove 211 is opened on the bottom surface of the rotating base 20. The spring 212 is placed in the receiving groove 211. One end of the guide 213 is engaged with the spring 212, and the other end of the guide 213 is adapted to the positioning tooth groove 13. Under the elastic force of the spring 212, the guide 213 abuts against the positioning tooth groove 13.

[0079] Regarding the arrangement of the receiving groove 211: A receiving groove 211 is provided vertically upward on the bottom surface of the rotating base 20 (i.e., the side facing the base assembly 10). The receiving groove 211 is preferably a circular countersunk hole structure, the diameter of which is large enough to accommodate the installation of the spring 212 and the guide 213, and has a certain depth to provide the compression stroke of the spring 212.

[0080] Regarding the structure of guide component 213: (combination) Figure 2 As shown, the guide member 213 in this embodiment adopts a metal pin structure. Specifically, the guide member 213 is divided into three parts from top to bottom:

[0081] The upper part is a guide post, the diameter of which is slightly smaller than the inner diameter of the spring 212. It is used to insert into the spring 212 to prevent the spring 212 from bending laterally or bouncing when compressed.

[0082] The middle part is provided with an outwardly protruding limiting flange. The outer diameter of the limiting flange is in clearance fit with the inner diameter of the receiving groove 211, which plays a guiding role like a piston. At the same time, its upper surface serves as a force-bearing surface to support the elastic force of the spring 212.

[0083] The lower part is an abutment joint, the end of which is machined into a conical or spherical shape, which is adapted to the cross-sectional shape of the positioning tooth groove 13 on the base tooth ring 12.

[0084] During assembly, spring 212 is placed into the receiving groove 211 of the rotating base 20. The guide post of guide member 213 is inserted into the center of spring 212 until the bottom end of spring 212 abuts against the limiting flange in the middle of guide member 213. Under the preload of spring 212, the abutment at the lower part of guide member 213 is pushed downward out of receiving groove 211 and pressed into the positioning tooth groove 13 of base assembly 10.

[0085] When the rotating seat 20 rotates, the tapered abutment at the bottom of the guide 213 is squeezed by lateral force, overcoming the resistance of the spring 212 and retracting upwards, thus sliding over the tooth ridge of the positioning groove 13. Because the abutment adopts a tapered design and the positioning groove 13 uses a U-shaped groove design, the two make smooth contact during sliding. After rotating through a certain angle, the spring 212 drives the guide 213 downwards, causing the tapered abutment to wedge into the next positioning groove 13.

[0086] Furthermore, the base assembly 10 includes a support shell 14 and a flexible silicone layer covering the outer surface of the support shell; a counterweight 15 is provided inside the support shell 14, and the counterweight 15 is connected to the support shell 14 by screws.

[0087] To balance structural strength, aesthetics, and driving safety, the base assembly 10 in this embodiment specifically includes a support shell 14 at its core. The support shell 14 is preferably injection-molded from high-strength engineering plastics such as ABS or PC, and is used to mount the gear ring 12 and withstand the pressure of the rotating seat 20. A flexible silicone layer is applied to the outside of the support shell 14. This flexible silicone layer is fixed to the outer surface of the support shell 14 using an overmolding or sleeve process. The flexible silicone layer not only provides a skin-friendly, non-slip feel, but more importantly, it acts as a buffer in the event of sudden braking or a collision, preventing hard plastic from directly impacting the user or scratching the car's interior.

[0088] To lower the overall center of gravity of the support and solve the problem of wobbling in the plastic base of existing technology, a counterweight 15 is also provided in the internal cavity of the support shell 14. The counterweight 15 is fastened to the inner bottom surface of the support shell 14 with screws. The screw locking method is more secure than simple glue adhesion and can prevent the counterweight 15 from falling off during long-term driving bumps or causing abnormal noises inside the shell.

[0089] Furthermore, the front surface of the support back plate 31 is recessed to form a receiving groove, and an anti-slip pad 311 is embedded in the receiving groove. The surface of the anti-slip pad 311 is provided with anti-slip texture.

[0090] To better protect the phone and improve clamping stability, this embodiment designs the front surface of the support backplate 31. The front surface of the support backplate 31 is not flat, but rather recessed to form a receiving groove. An anti-slip pad 311, made of silicone or rubber, is embedded (or adhered) within the receiving groove. The thickness of the anti-slip pad 311 is slightly greater than the depth of the receiving groove, causing its surface to slightly protrude from the support backplate 31, ensuring that the back of the phone contacts the pad first, rather than the hard plastic. Furthermore, the surface of the anti-slip pad 311 is molded with an anti-slip texture (such as leather texture, grain texture, or stripes). On one hand, the pad prevents direct friction between the phone and the hard backplate, preventing scratches on the phone's back cover; on the other hand, the anti-slip texture increases static friction, assisting the bracket assembly 30 in preventing the phone from sliding down, even during severe vehicle bumps.

[0091] Furthermore, an adhesive layer 16 is attached to the bottom plane of the base assembly 10, which is used to adsorb and fix the base assembly 10 to the bearing surface.

[0092] To securely mount the bracket on the car dashboard, an adhesive layer 16 is adhered to the bottom surface of the base assembly 10. In this embodiment, the adhesive layer 16 has strong adsorption capacity, adapting to common car dashboard surfaces such as leather, slush molding, or hard plastic, and filling in the fine textures of the surface. After the base assembly 10 is fixed to the bearing surface by the adhesive layer 16, the internal counterweight 15 further stabilizes the entire bracket, preventing displacement or tilting when placing or rotating the phone.

[0093] In summary, this utility model achieves precise 360-degree circumferential indexing and positioning rotation by setting a toothed ring component inside the base assembly and cooperating with the elastic abutment mechanism at the bottom of the rotating seat. At the same time, by utilizing the sliding groove, sliding mounting seat and elastic reset component on the seat panel, the linear reciprocating motion and automatic clamping function of the bracket assembly are realized. In addition, the base assembly adopts a counterweight design, which makes the bracket more stable in the driving environment.

[0094] The working principle of this vehicle-mounted phone holder is as follows: When the user needs to adjust the phone's viewing angle, rotating the rotating base causes the elastic abutment mechanism at its bottom to overcome spring resistance, slide on the gear ring of the base assembly, and sequentially engage with different positioning grooves, thereby achieving circumferential positioning of the rotating base relative to the base assembly. When the user needs to secure the phone, pushing the holder assembly outward causes the internal sliding mounting seat to move along the slide groove and compress the elastic reset component, opening the holder assembly from the fixed C-shaped bracket. After placing the phone in, releasing the grip causes the elastic reset component to release its elastic force, driving the sliding mounting seat to reset, allowing the holder assembly to clamp the phone securely with the C-shaped bracket. The base assembly lowers its center of gravity with a counterweight and adheres to the dashboard via a bottom adhesive layer, maintaining overall stability.

[0095] Other structures of the vehicle-mounted mobile phone holder described in this utility model are described in the prior art.

[0096] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
