Description

Technical Field

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

[0002] With the widespread use of smartphones, car phone holders have become an indispensable accessory in car interiors. Existing car phone holders typically include a base and a support head, and some high-end holders also integrate wireless charging functionality.

[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. CN2250950U discloses a wireless charging phone holder. According to the patent specification and drawings, it includes a fixed base and a backrest structure connected to the fixed base. A wireless charging coil is disposed within the backrest structure.

[0004] However, after practical use and in-depth research of the above-mentioned existing technologies, the following significant technical defects were found: The tilt angle is not adjustable and it cannot be folded: In the comparison document CN2250950U, the backrest structure and the mounting base are set at a fixed obtuse angle (clearly stated in paragraph

[0027] of the instruction manual). This one-piece or fixed-angle design makes it impossible for the driver to adjust the tilt angle of the phone, making it difficult to accommodate drivers of different heights or eliminate screen glare. At the same time, since the backrest cannot be folded flat, when the stand is not used, the tall backrest will continuously obstruct part of the driver's view, which is not only inconvenient to store, but also easy to cause secondary injury to the occupants in the event of a collision.

[0005] Limited rotation angle: Although the base of this comparative document is designed with a rotating structure, its instruction manual clearly states that the length of the fixed position is 1 / 6 of the current ring's circumference, meaning it can only rotate within a limited range of about 60 degrees, and cannot achieve true 360-degree full-circumference free rotation. This is limited when the driver needs to make significant adjustments to the direction (e.g., turning the phone to the passenger seat to view).

[0006] Poor base stability: Existing mounting bases are typically assembled from lightweight plastic shells, resulting in a high center of gravity. During severe bumps or jolting while driving, this can easily cause resonance or wobbling, affecting the viewing experience.

[0007] Therefore, there is a need for a vehicle mount that can be folded and stored, has an adjustable tilt angle, and can achieve 360-degree positioning and rotation to solve the above problems. Utility Model Content

[0008] In order to overcome the technical defects of the existing technology, such as the inability to adjust the pitch angle of the magnetic charging point and the limitation of the bracket rotation angle, this utility model provides a vehicle-mounted wireless charging mobile phone holder.

[0009] To solve the above problems, this utility model is implemented according to the following technical solution: The present invention relates to a vehicle-mounted wireless charging phone holder, comprising: A base assembly having a receiving cavity, the inner wall of which is fixedly connected to a gear ring member, the upper surface of which is evenly distributed with a plurality of positioning tooth grooves along the circumferential direction. A rotating base is disposed within the receiving cavity of the base assembly. The bottom of the rotating base is provided with an elastic abutting mechanism, which elastically engages with the positioning tooth groove. 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. A bracket assembly is hinged to the top of the rotating base. The bracket assembly includes a support back plate for supporting a mobile phone. A magnetic component is provided in the central area of ​​the support back plate. The magnetic component is used to attract the mobile phone or to wirelessly charge the mobile phone. The supporting back plate has a folded storage state and an upright supporting state; The support back plate can be angled relative to the rotating base in a folded storage state and an upright support state.

[0010] Furthermore, the bottom of the support back plate is provided with a pivot lug, the top of the rotating seat is provided with a corresponding shaft mounting seat, and a damping pivot is passed between the pivot lug and the shaft mounting seat; A damping fit is formed between the outer wall of the damping shaft and the inner wall of the shaft mounting base; In the folded storage state, the support back plate folds downward and fits against the upper surface of the rotating base under the action of damped friction, so as to reduce the storage volume; In the vertical support state, the support back plate overcomes the frictional force of the damping engagement, rotates around the damping axis to a predetermined angle, and hovers to form support for the mobile phone.

[0011] Furthermore, the elastic abutment mechanism includes a receiving groove, a spring, and a guide member; 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.

[0012] Furthermore, the base assembly includes a support shell and a flexible silicone layer covering the outer surface of the support shell; The support shell has a counterweight inside, which is connected to the support shell by screws.

[0013] Furthermore, a circular magnetic positioning platform is protruding from the front surface of the support back plate, and the magnetic assembly is built into the magnetic positioning platform. The surface of the magnetic positioning platform is covered with an anti-slip silicone pad, which is used to increase the friction between the magnetic positioning platform and the contact surface of the mobile phone.

[0014] 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.

[0015] Furthermore, a decorative cover plate is fastened to the outer side of the connection between the shaft lug and the shaft mounting seat. The decorative cover plate is used to cover the end of the damping shaft and the mounting hole.

[0016] Furthermore, the side of the bracket assembly has a charging port.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This invention relates to a car-mounted wireless charging phone holder. By incorporating a fixedly connected toothed ring component within the base assembly, coupled with an elastic abutment mechanism at the bottom of the rotating seat, it structurally overcomes the limitation of existing holders that can only rotate at small angles due to the restricted sliding track. When the rotating seat rotates, the elastic abutment mechanism slides on the toothed ring component and sequentially engages with different positioning tooth slots, achieving true 360-degree free rotation. Simultaneously, utilizing elastic engagement, a mechanical lock or high-damping state is formed when rotation stops, overcoming the bumps and inertia generated during vehicle movement, preventing accidental circumferential displacement of the holder, and ensuring a stable navigation viewing angle. The holder assembly of this invention is hinged to the top of the rotating seat, overcoming the rigid design of existing technologies where the back panel and base form a fixed obtuse angle and cannot be adjusted. Users can freely adjust the tilt angle of the support back panel between the folded storage state and the upright support state according to their height, posture, or light reflection conditions to obtain the optimal viewing angle. When not in use, the support back panel can be folded down to flatten the product, reducing its size, preventing obstruction of the driver's view, and improving driving safety and the tidiness of the vehicle interior. This invention integrates a magnetic component in the center of the support back panel, using magnetic attraction to hold the phone. Compared to traditional mechanical clamping arm structures, users do not need to use their hands to open the clamping arms; simply bringing the phone close will automatically attract and position it, initiating wireless charging.

Detailed Implementation

[0019] 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.

[0020] like Figures 1-3 As shown, the present invention provides a vehicle-mounted wireless charging phone holder, comprising: The base assembly 10 has a receiving cavity 11, and a toothed ring 12 is fixedly connected to the inner wall of the receiving cavity 11. The upper surface of the toothed ring 12 has a plurality of positioning tooth grooves 13 evenly distributed along the circumferential direction. The rotating seat 20 is disposed in 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 elastically engages with the positioning tooth groove 13. When the rotating seat 20 rotates, the elastic abutting mechanism 21 slides on the gear ring 12 and sequentially engages in different positioning tooth grooves 13 to achieve circumferential positioning of the rotating seat 20 relative to the base assembly 10. The bracket assembly 30 is hinged to the top of the rotating base 20. The bracket assembly 30 includes a support back plate 31 for supporting the mobile phone. A magnetic component 32 is provided in the central area of ​​the support back plate 31. The magnetic component 32 is used to attach the mobile phone or to wirelessly charge the mobile phone. Among them, the support back plate 31 has a folded storage state and an upright support state; The support back plate 31 can be angled relative to the rotating base 20 between the folded storage state and the upright support state.

[0021] As shown in the figure, this embodiment provides a vehicle-mounted wireless charging phone holder, which is mainly composed of three parts: a base assembly 10, a rotating seat 20, and a bracket assembly 30.

[0022] Regarding the arrangement of the base assembly 10 and the rotating structure: The base assembly 10 serves as the mounting base for the bracket, and its main body has an inwardly recessed receiving cavity 11. A gear ring member 12 is fixedly connected to the inner wall of the receiving cavity 11, specifically to the annular bearing surface at the bottom of the receiving cavity 11. 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, forming a closed, wave-like or sawtooth-like positioning track.

[0023] The rotating base 20 is rotatably disposed within the receiving cavity 11 of the base assembly 10. To achieve the indexing and 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 its lower end extends downward under the action of elastic force, forming an elastic meshing engagement with the positioning tooth groove 13 on the gear ring member 12.

[0024] When the user rotates the rotating base 20, the rotating base 20 drives the elastic abutment mechanism 21 at the bottom to move relative to the base assembly 10. The elastic abutment mechanism 21 slides on the surface of the gear ring 12, overcomes the spring resistance, slides out of the current positioning tooth groove 13, and sequentially engages in different positioning tooth grooves 13. This engagement method achieves circumferential positioning of the rotating base 20 relative to the base assembly 10, allowing the bracket to be rotated and adjusted 360 degrees. At the same time, the mechanical blocking effect of the positioning tooth groove 13 on the elastic abutment mechanism 21 ensures that the bracket maintains a stable viewing angle when it stops rotating, preventing accidental rotation due to vehicle bumps.

[0025] Regarding the bracket assembly 30 and the folding structure: The bracket assembly 30 is located on the top of the rotating base 20. Unlike traditional fixed brackets, the bracket assembly 30 in this embodiment is connected to the rotating base 20 via a hinged structure. The core component of the bracket assembly 30 is the support back plate 31 for supporting the mobile phone. Thanks to the hinged connection, the support back plate 31 has two working modes: a folded storage state and an upright support state, and the angle can be adjusted between the two.

[0026] Vertical support state: When navigation is needed, the user can pull the support back plate 31 upward to rotate it around the hinge point to a suitable viewing angle. At this time, the damping force at the hinge can support the weight of the phone and keep it suspended.

[0027] Folded storage state: When the bracket is not needed, the user can press the support back plate 31 down to fold it and fit it against the surface of the rotating base 20, thereby reducing the height and volume of the bracket and making it easier to store.

[0028] A magnetic attachment assembly 32 is provided in the central area of ​​the support back plate 31. This magnetic attachment assembly 32 is used to attach a mobile phone or a mobile phone case with magnetic function, thereby securing the mobile phone. At the same time, this magnetic attachment assembly 32 can be used to wirelessly charge the mobile phone.

[0029] Furthermore, the bottom of the support back plate 31 is provided with a pivot lug 311, the top of the rotating seat 20 is provided with a corresponding shaft mounting seat 22, and a damping pivot 33 passes through between the pivot lug 311 and the shaft mounting seat 22. A damping fit is formed between the outer wall of the damping shaft 33 and the inner wall of the shaft mounting seat 22; In the folded storage state, the support back plate 31 folds down and fits against the upper surface of the rotating base 20 under the action of the damped friction force to reduce the storage volume. In the upright support state, the support back plate 31 overcomes the frictional force of the damping engagement and rotates around the damping axis 33 to a predetermined angle and hovers, so as to form support for the mobile phone.

[0030] This embodiment provides a detailed description of the connection structure and motion state between the support back plate 31 and the rotating base 20. Regarding the shaft connection structure: a shaft lug 311 extends downwards from the bottom of the support back plate 31. A shaft mounting seat 22, consisting of a mounting groove formed by two protruding brackets, is correspondingly provided on the top surface of the rotating base 20. A damping shaft 33 passes laterally through the shaft lug 311 and the shaft mounting seat 22, hinged together with the support back plate 31 and the rotating base 20.

[0031] Regarding the damping fit principle: The outer wall of the damping shaft 33 and the inner wall of the shaft mounting base 22 are not clearance fits, but rather form a damping fit (e.g., through an interference fit or by adding a damping rubber ring). This fit generates a predetermined frictional torque on the rotating contact surface. The magnitude of the frictional torque is set to be sufficient to support the weight of the backplate 31 and the mobile phone, but less than the rotational torque applied by the user's hand.

[0032] Regarding the switching of working states: Folded storage state: When the stand is not needed, the user presses down on the support back plate 31. Under the action of the damped friction, the support back plate 31 folds down around the damping pivot 33 until its back surface is against the upper surface of the rotating base 20. In this state, the overall height of the stand is reduced, thus reducing the storage volume.

[0033] Vertical support state: When the stand is needed, the user pulls the support back plate 31 upward. The support back plate 31 overcomes the frictional force of the damping engagement and rotates around the damping pivot 33. When it rotates to the predetermined angle required by the user and the external force is removed, the static friction torque generated by the damping engagement keeps the support back plate 31 suspended at that angle, thereby providing support for the mobile phone.

[0034] Furthermore, the elastic abutment mechanism 21 includes a receiving groove 211, a spring 212, and a guide member 213; 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] In practical applications, the shape of the positioning groove 13 can be adjusted according to the required damping force: 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.

[0039] 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.

[0040] 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.

[0041] Furthermore, regarding the arrangement of the receiving groove 211: a receiving groove 211 is vertically formed on the bottom surface of the rotating base 20 (i.e., the side facing the base assembly 10). The receiving groove 211 is designed as a countersunk hole structure with a certain depth, and its diameter is adapted to the installation of the spring 212 and the guide member 213.

[0042] Regarding the connection of internal components: the elastic abutment mechanism 21 includes a spring 212, preferably a helical spring, and a guide 213, preferably a metal pin.

[0043] Spring mounting: Spring 212 is placed inside the receiving groove 211. Guide connection: One end (upper end) of guide 213 is designed with a connection structure, which is snapped into or inserted into spring 212 to prevent spring 212 from shifting laterally during compression.

[0044] Matching relationship: The other end (lower end) of the guide member 213 is designed as a conical or hemispherical abutment, which is adapted to the cross-sectional shape of the positioning tooth groove 13 on the base tooth ring member 12.

[0045] Working principle: After assembly, under the preload of the spring 212, a portion of the guide 213 extends downward into the receiving groove 211 and abuts tightly against the positioning tooth groove 13. When the rotating seat 20 rotates, the guide 213 is compressed upward by lateral force, compressing the spring 212 in the receiving groove 211; after passing the tooth ridge, the spring 212 releases its elasticity, driving the guide 213 to pop downward and engage with the next positioning tooth groove 13, thereby achieving the positioning function.

[0046] Furthermore, the base assembly 10 includes a support shell 14 and a flexible silicone layer covering the outer surface of the support shell 14; The support shell 14 has a counterweight 15 inside, which is connected to the support shell 14 by screws.

[0047] 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.

[0048] 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 specially set 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.

[0049] Furthermore, a circular magnetic positioning platform 312 is protruding from the front surface of the support back plate 31, and the magnetic assembly 32 is built into the magnetic positioning platform 312. The surface of the magnetic positioning platform 312 is covered with an anti-slip silicone pad 313, which is used to increase the friction between the magnetic positioning platform 312 and the contact surface of the mobile phone.

[0050] Regarding the configuration of the magnetic positioning platform 312: A magnetic positioning platform 312 is provided protruding outward on the front surface of the support back plate 31 (i.e., the side facing the mobile phone). The magnetic positioning platform 312 is preferably designed as a circular stepped structure, the diameter of which is adapted to the wireless charging receiving area or magnetic ring on the back of the mobile phone, to assist the user in aligning the mobile phone.

[0051] Regarding the installation of internal components: The magnetic component 32 is built into the internal accommodating space of the magnetic positioning platform 312.

[0052] Regarding the anti-slip design: A layer of anti-slip silicone pad 313 covers the surface of the magnetic positioning platform 312. The anti-slip silicone pad 313 is fixed to the surface of the positioning platform by adhesive bonding or secondary injection molding. Its function is to increase the friction between the magnetic positioning platform 312 and the contact surface of the mobile phone by utilizing the frictional properties of silicone material. When the stand is in an inclined support state or the vehicle is bumpy, the anti-slip silicone pad 313 can work with the magnetic force to prevent the mobile phone from sliding or rotating on the contact surface.

[0053] 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.

[0054] 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.

[0055] Furthermore, a decorative cover plate 34 is fastened to the outer side of the connection between the pivot lug 311 and the shaft mounting base 22. The decorative cover plate 34 is used to cover the end of the damping pivot 33 and the mounting hole. The side of the bracket assembly 30 has a charging interface 35.

[0056] In summary, this utility model achieves 360-degree positioning and rotation by cooperating with the toothed ring component in the base assembly and the elastic abutment mechanism at the bottom of the rotating seat; it enables free switching between folding storage and multi-angle vertical support by cooperating with the hinged support back plate and the damping pivot; the magnetic component and the anti-slip silicone pad enable convenient phone fixation and wireless charging; and the counterweight design of the base assembly further enhances the stability and safety of the bracket.

[0057] The working principle of this in-vehicle wireless charging phone holder is as follows: When the user needs to adjust the phone's orientation, rotating the 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 use the holder, lifting the support back plate allows it to overcome the friction of the damping shaft, rotate to a predetermined angle, and hover; placing the phone near the magnetic positioning platform causes the magnetic assembly to automatically attract and fix the phone for wireless charging. When not in use, pressing down the support back plate folds it to fit snugly against the surface of the rotating base. The base assembly is held firmly on the dashboard by internal counterweights and a bottom adhesive layer.

[0058] Other structures of the vehicle-mounted wireless charging phone holder described in this utility model are described in the prior art.

[0059] 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.
