Description

Technical Field

[0001] This utility model belongs to the field of mobile phone holder technology, specifically a multifunctional magnetic mobile phone holder. Background Technology

[0002] Currently, there are many types of phone holders on the market. According to the fixing method, they can be mainly divided into clamp type, magnetic type, and suction cup type. Clamp type holders mostly use a spring clip structure to fix the phone through mechanical clamping force. They can fit phones of different sizes and are commonly found in ordinary desktop holders and car holders. Magnetic type holders rely on the attraction force of magnets. If the phone itself has a magnetic function (such as some Apple phone series), it can be directly attached. If not, a magnetic sheet needs to be attached to the back of the phone to achieve fixation. They are often used in car center console holders and some portable holders. Suction cup type holders are attached to smooth surfaces, such as windshields and desktops, to support the phone.

[0003] In terms of functionality, some high-end phone holders have expanded features, such as some car holders with wireless charging capabilities, which can charge the phone while securing it; some holders also use structures such as universal ball joints to allow for multi-angle rotation and adjustment of the phone to meet the needs of users with different viewing angles; and some holders adopt special mechanical structure designs to enhance stability, such as double triangle supports and gravity locking devices.

[0004] The existing stents have the following shortcomings:

[0005] Poor durability: Some stands are prone to failure after long-term use. For example, after a period of use, the damping between the ring and the base of the ring holder is significantly weakened or even completely lost, causing the desktop stand to malfunction. Some stands that use passive friction to maintain the angle will experience wear and tear on the friction structure at the connection of the support arm after long-term use, resulting in reduced resistance and insufficient support, making the phone prone to tilting or falling. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a multifunctional magnetic mobile phone holder, which solves the problem of poor durability of existing mobile phone holders.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional magnetic phone holder, comprising a base, a connecting cover snapped onto the bottom of the base, a first support arm rotatably connected to the top of the connecting cover, a second support arm rotatably connected to the other end of the first support arm, a third support arm rotatably connected to the other end of the second support arm, a ball at the end of the third support arm, a support base movably connected to the end of the third support arm via the ball, a magnetic block embedded in the support base, and a connecting shaft provided between the first support arm and the connecting cover, the second support arm and the first support arm, and the third support arm and the second support arm, and a locking mechanism provided within the connecting shaft for use with the first support arm, the second support arm, and the third support arm;

[0008] The locking mechanism includes a connecting rod fixed to one side of the connecting shaft. A threaded rod is fixedly connected to the other end of the connecting rod. An adjusting disc is threadedly connected to the outer side of the threaded rod, and the adjusting disc is located outside the connecting shaft. A pressing block is slidably connected to the connecting shaft in a symmetrical structure. A connecting cylinder is fixedly connected between the pressing blocks. The other end of each pressing block is fixedly connected to the inner side of the adjusting disc. Multiple sets of locking blocks that cooperate with the pressing blocks are slidably connected to the connecting shaft. Each locking block has a frustum-shaped structure. Gear rings that cooperate with the locking blocks are connected to the inner sides of the first, second, and third support arms. External teeth that cooperate with the gear rings are formed on the outer side of the locking blocks.

[0009] As a further embodiment of this utility model: protrusions are fixedly connected to the top two sides of the locking block in a symmetrical structure, and a tension spring is fixedly connected between the top of the protrusion and the outer side of the connecting shaft.

[0010] As a further embodiment of this utility model: the locking block has a semi-arc structure, and a slot is provided on the outer side of the connecting shaft to cooperate with the locking block.

[0011] As a further embodiment of this utility model: a threaded tube is provided on the outer side of the support base, the support base is connected to the ball through the threaded tube, and a nut is threadedly connected to the outer side of the threaded tube, the nut being located on the outer side of the third support arm.

[0012] As a further embodiment of this utility model: the bottom of the base is provided with a suction cup, and the support base has a circular structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The bracket is flexible in adjustment and precise in locking. The multi-segment support arm can rotate at multiple angles through the connecting shaft. With the threaded engagement of the adjusting disc and the threaded rod in the locking mechanism, the support arm can be quickly unlocked and locked. At the same time, the support base can be precisely fixed in orientation through the combination of threaded tube, ball and nut to meet the needs of different scenarios. It is easy to operate and has a wide range of adjustment.

[0015] 2. The locking force is transmitted through the mechanical meshing of the outer teeth of the locking block and the toothed ring. The tension spring assists in the reset of the locking block and the slotting ensures smooth sliding. After long-term use, the rotating adjustment plate can increase the squeezing force to compensate for wear and avoid the weakening of support force. The suction cup of the base also further improves the overall stability, effectively solving the problem of insufficient support after long-term use of existing brackets. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution:

[0025] A multifunctional magnetic phone holder includes a base 1, a connecting cover 2 snapped onto the bottom of the base 1, a first support arm 3 rotatably connected to the top of the connecting cover 2, a second support arm 4 rotatably connected to the other end of the first support arm 3, a third support arm 5 rotatably connected to the other end of the second support arm 4, a ball at the end of the third support arm 5, and a support base 7 movably connected to the end of the third support arm 5 via the ball. A magnetic block 8 is embedded in the support base 7. A connecting shaft 9 is provided between the first support arm 3 and the connecting cover 2, between the second support arm 4 and the first support arm 3, and between the third support arm 5 and the second support arm 4. A locking mechanism is provided in the connecting shaft 9 to cooperate with the first support arm 3, the second support arm 4, and the third support arm 5.

[0026] The locking mechanism includes a connecting rod 10, which is fixed to one side of the connecting shaft 9. The other end of the connecting rod 10 is fixedly connected to a threaded rod 11. An adjusting plate 12 is threadedly connected to the outside of the threaded rod 11. The adjusting plate 12 is located outside the connecting shaft 9. An extrusion block 13 is slidably connected inside the connecting shaft 9 in a symmetrical structure. A connecting cylinder 14 is fixedly connected between the extrusion blocks 13. The other end of the extrusion block 13 is fixedly connected to the inside of the adjusting plate 12. Multiple sets of locking blocks 15 that cooperate with the extrusion blocks 13 are slidably connected on the connecting shaft 9. The locking block 15 has a frustum-shaped structure. The inner sides of the first support arm 3, the second support arm 4, and the third support arm 5 are connected to toothed rings 19 that cooperate with the locking block 15. The outer side of the locking block 15 is provided with external teeth that cooperate with the toothed rings 19.

[0027] Specifically, in use, multi-angle adjustment is achieved through the sequential rotational connection of the first support arm 3, the second support arm 4, and the third support arm 5. The connecting cover 2 is connected to the first support arm 3, the first and second support arms 4, and the second and third support arms 5 through the connecting shaft 9 to form a rotatable joint structure. The ball at the end of the third support arm 5 is movably connected to the support seat 7, which can further adjust the orientation of the support seat 7. The magnetic block 8 embedded in the support seat 7 is used to attract the mobile phone for quick fixation. The locking mechanism actively controls the locking state of the support arm joint through the cooperation of the adjusting disc 12 and the threaded rod 11. When it is necessary to adjust the angle of the support arm, the adjusting disc 12 is rotated in the opposite direction. Since the adjusting disc 12 is threadedly connected to the threaded rod 11 and the threaded rod 11 is fixed in the connecting shaft 9 through the connecting rod 10, the adjusting disc 12 will move outward along the axial direction of the threaded rod 11, causing the pressing block 13 to slide outward synchronously. The pressing force on the locking block 15 disappears, and the locking block 15 slides inward along the connecting shaft 9. The outer teeth on its outer side separate from the toothed ring 19 on the inner side of the support arm, and the support arm can rotate freely to unlock.

[0028] Once the support arm angle is adjusted to the correct position, rotate the adjustment disc 12 in the forward direction. The adjustment disc 12 moves inward along the threaded rod 11, causing the pressing block 13 to slide inward synchronously. The pressing block 13 presses the locking block 15, causing the locking block 15 to slide outward along the connecting shaft 9. Its outer teeth mesh tightly with the toothed ring 19 on the inner side of the support arm, achieving joint locking. Furthermore, if the initial locking force of the support arm joint decreases due to slight wear after prolonged use, the pressing force can be increased by rotating the adjustment disc 12, making the engagement between the locking block 15 and the toothed ring 19 tighter, restoring the support force and preventing the phone from falling.

[0029] This structure significantly improves upon the technical problems of reduced resistance and insufficient support force between the support arms after prolonged use of existing mobile phone holders. Existing mobile phone holders rely on passive friction to maintain the angle, and the friction coefficient decreases after wear, resulting in irreversible reduction in resistance. This design actively controls the position of the compression block 13 through the threaded engagement of the adjusting disc 12 and the threaded rod 11, thereby achieving active adjustment of the locking force and solving the pain point of resistance attenuation in the existing technology. At the same time, the meshing structure of the external teeth of the locking block 15 and the toothed ring 19 of the support arm provides the locking force through mechanical meshing. Even if slight wear occurs after long-term use, the compression force can still be increased by the adjusting disc 12 to ensure a tight engagement and prevent slippage failure. Moreover, the independent adjustment of multiple joints can adapt to various scenarios. The adjusting disc 12 is located outside the connecting shaft 9, and users can directly rotate it manually for convenient operation.

[0030] The top two sides of the locking block 15 are fixedly connected with protrusions 16 in a symmetrical structure. A tension spring 17 is fixedly connected between the top of the protrusion 16 and the outside of the connecting shaft 9. The locking block 15 has a semi-arc structure, and the outside of the connecting shaft 9 is provided with a slot 18 for use with the locking block 15. A threaded tube is provided on the outside of the support base 7. The support base 7 is connected to the ball through the threaded tube, and a nut 6 is threaded on the outside of the threaded tube. The nut 6 is located on the outside of the third support arm 5. A suction cup is provided at the bottom of the base 1. The support base 7 has a circular structure.

[0031] Specifically, the bracket is fixed to a flat surface such as a desktop by the suction cup at the bottom of the base 1. Then, the support arm is adjusted according to the usage requirements. During adjustment, the adjustment plate 12 on the outside of the connecting shaft 9 is rotated. Since the adjustment plate 12 is threadedly connected to the threaded rod 11, and the threaded rod 11 is fixed in the connecting shaft 9 by the connecting rod 10, rotating the adjustment plate 12 in the opposite direction will cause it to move outward along the axial direction of the threaded rod 11, which will drive the pressing block 13 to slide outward synchronously. At this time, the tension spring 17 in the protrusions 16 on both sides of the top of the locking block 15 will pull the locking block 15 to slide inward along the slot 18 on the connecting shaft 9. The outer teeth on the outside of the locking block 15 separate from the toothed ring 19 on the inside of the support arm, and the support arm can be unlocked and rotated freely. After adjusting to a suitable angle, the adjustment plate 12 is rotated in the forward direction to move inward along the axial direction of the threaded rod 11, which will drive the pressing block 13 to press the locking block 15, overcome the tension of the tension spring 17, and make the locking block 15 slide outward along the slot 18. The outer teeth and the toothed ring 19 are tightly engaged to achieve locking.

[0032] Next, adjust the support base 7, rotate the nut 6 on the outside of the third support arm 5 to move it along the threaded tube on the outside of the support base 7, loosen the fixation of the ball, adjust the support base 7 to the appropriate orientation, then rotate the nut 6 in the opposite direction to lock the ball, and finally attach the mobile phone to the magnet 8 embedded in the support base 7.

[0033] The semi-circular structure of the locking block 15, in conjunction with the slot 18 of the connecting shaft 9, ensures the stability of the sliding of the locking block 15. The protrusion 16 and the tension spring 17 automatically pull the locking block 15 back to its original position during unlocking, making unlocking smoother and less strenuous, and preventing the locking block 15 from jamming. The support base 7 is connected to the ball through a threaded tube and fixed with the nut 6, which can accurately lock the orientation of the support base 7 and prevent loosening during use. The circular structure of the support base 7 is suitable for more sizes of mobile phones. The suction cup of the base 1 enhances the overall stability of the bracket and prevents it from tipping over during use. The overall structural design further improves the convenience of adjustment and the reliability of locking, extends the service life, and better meets the diverse needs of users.

[0034] The working principle of this utility model is as follows:

[0035] First, the basic adjustment function is achieved through the rotational connection of multiple support arms. The first support arm 3, the second support arm 4, and the third support arm 5 are rotatably connected in sequence. The connecting cover 2 and the first support arm 3, the first and second support arms 4, and the second and third support arms 5 are connected by the connecting shaft 9 to form a rotatable joint structure. With the movable connection between the ball at the end of the third support arm 5 and the support base 7, multi-angle adjustment is achieved. The magnetic block 8 embedded in the support base 7 is used to quickly adsorb and fix the mobile phone.

[0036] Secondly, the locking and unlocking of the support arm joint is achieved by relying on the locking mechanism. In the locking mechanism, the connecting rod 10 fixes the threaded rod 11 inside the connecting shaft 9. The adjusting plate 12 is threadedly connected to the threaded rod 11 and its inner side is fixed to the pressing block 13. When the adjusting plate 12 is rotated in the reverse direction, it moves outward along the axial direction of the threaded rod 11, causing the pressing block 13 to move outward synchronously. The pressing force on the locking block 15 disappears, and the locking block 15 slides inward along the connecting shaft 9. The outer outer teeth separate from the inner toothed ring 19 of the support arm, and the support arm can be unlocked and rotated freely. When the adjusting plate 12 is rotated in the forward direction, the adjusting plate 12 moves inward, causing the pressing block 13 to press the locking block 15, so that the locking block 15 moves outward and engages with the toothed ring 19 through the outer teeth, thereby locking the joint. After long-term use, the pressing force can be increased by rotating the adjusting plate 12 to compensate for the decrease in locking force caused by wear.

[0037] It is worth mentioning that the protrusion 16 on the top of the locking block 15 cooperates with the tension spring 17 on the outside of the connecting shaft 9, which can automatically pull the locking block 15 back to its original position when unlocking. The semi-circular locking block 15 is adapted to the slot 18 on the connecting shaft 9 to ensure sliding stability. At the same time, the support seat 7 is connected to the ball through a threaded tube. With the nut 6 on the outside of the third support arm 5, the orientation of the support seat 7 can be precisely locked to prevent loosening.

[0038] Finally, the suction cup at the bottom of the base 1 can firmly fix the bracket on the plane. Through the synergistic effect of each component, the overall structure not only achieves flexible multi-angle adjustment, but also solves the problem of insufficient support after long-term use of existing brackets through active adjustment locking, thereby improving the reliability and lifespan of the bracket.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
