Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone brackets, and more specifically to strap brackets.

Background Art

[0002] With the development of society, mobile phones are becoming an indispensable portable electronic device in people's daily life and work. Of course, regardless of communication, information acquisition, entertainment, and mobile office, mobile phones play a very important role. However, in many scenarios, such as driving a vehicle, making a video call, watching a movie program, or exercising, holding a mobile phone is not only inconvenient to operate but also poses a safety risk or may lead to hand fatigue. To solve this problem, various mobile phone brackets have emerged, providing a convenient mobile phone support member solution for users.

[0003] After searching, the Chinese utility model with publication number CN221227586U discloses a mobile phone strap bracket. By using a structure where the slide member is inclined, the frictional force between the slide member and the chute is reduced, and the slide is smooth. However, its elastic contact point is made of a metal material. In the actual use process, after multiple uses, abnormal wear is caused to other parts of the bracket. Especially the part itself that is compressed by the elastic contact point is in a thin state. After being worn multiple times by the elastic contact point, the structural strength and service life in support are extremely reduced, increasing the risk of bracket damage.

Summary of the Invention

Problems to be Solved by the Invention

[0004] To overcome the above defects of the prior art, the present invention provides a strap bracket for solving the problems existing in the above background art.

Means for Solving the Problems

[0005] This invention provides the following technical solution: a strap bracket comprising a bracket body having a chute opened above it and at least two locking positions on both sides of the chute; a sliding member slidably mounted inside the chute and integrally molded with locking bumps on both sides that are stopped by one of the locking positions; and a strap body having one end attached to the bracket body and the other end attached to the sliding member.

[0006] A further aspect of this invention further includes an initial locking position, which is located at one end of the chute, and the strap body is under tension when the locking bump is located within the initial locking position.

[0007] As a further aspect of the present invention, the two locking positions include a first locking position and a second locking position located away from the sliding member of the first locking position.

[0008] As a further aspect of this invention, retractable openings are provided at both ends of the slide member, and a connecting portion is formed at both ends of the slide member with locking bumps attached.

[0009] As a further aspect of this invention, the connecting portion is linear.

[0010] As a further aspect of this invention, the connecting portion is "M" shaped, and an arc-shaped elastic plate is bonded to one side of the escape opening, with one end fixed to the escape opening.

[0011] As a further modification of the present invention, a mounting groove is further included, in which a magnetic ring is bonded, and a cap is bonded to the top of the magnetic ring, and after the cap is attached to the mounting groove, the top of the cap becomes flush with the top of the mounting groove.

[0012] As a further aspect of this invention, a guide groove is drilled through the bottom of the chute, and a stopper block that slides within the guide groove is integrally molded to the bottom of the sliding member.

[0013] As a further aspect of this invention, a guide groove and a fixing fastener that passes through the strap body are provided below the sliding member. [Effects of the Invention]

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention utilizes a locking position where the thickness of the side edge far exceeds the thickness of the bottom support portion. By transferring the wear that was originally concentrated in the bottom support portion to the locking position on the side edge, the wear rate is effectively slowed down, preventing the support structure from becoming inoperable due to excessive localized wear. This significantly reduces the risk of damage to the entire bracket and substantially extends the service life of the bracket.

[0016] 2. This invention provides a locking position on the side, which aligns with the locking bumps on both sides of the sliding member. By moving the sliding member along the chute and adjusting it to different positions, a stable lock is achieved, allowing for convenient adjustment of the degree of looseness of the strap body to adapt to different usage needs.

[0017] 3. This invention, by designing a linear connection section, effectively reduces material usage and production costs compared to conventional arc-shaped or bent structures, while ensuring structural strength. It also allows for a more direct force-receiving direction for the locking bump, avoiding the problem of reduced engagement accuracy between the locking bump and the locked or initial locking position due to deformation of the connection section.

[0018] 4. This invention, through the bending structure of the "M" shaped connection portion, can generate a more favorable elastic cushioning effect when the locking bump is subjected to force. Compared to a straight connection portion, its deformation capacity is stronger, and by further absorbing impact forces during the engagement and disengagement processes, it can more effectively protect the locking bump and the POM plastic ball block and reduce wear.

[Figure 3] This is a schematic diagram of the enlarged structure of the slide member of the present invention. [Figure 4] This is a schematic diagram of an enlarged structure of a slide member in another embodiment of the present invention. [Modes for carrying out the invention]

[0020] The following clearly and completely describes the technical concept of this invention, linking it with the drawings. The structural forms described in the following embodiments are merely illustrative examples, and the invention is not limited to the structures described in the following embodiments. All other embodiments obtained by a person skilled in the art without creative effort are all covered by this invention.

[0021] Referring to Figures 1 to 4, the present invention provides a strap bracket comprising a bracket body 1, a slide member 5, and a strap body 9. Above the bracket body 1, a chute 3 and a mounting groove 10 are provided. On both sides of the chute 3, at least two locking positions 6 are provided. A magnetic ring 11 is bonded to the mounting groove 10, and a cap 2 is bonded to the top of the magnetic ring 11. After the cap 2 is attached to the mounting groove 10, its top becomes flush with the top of the mounting groove 10. The slide member 5 is slidably mounted within the chute 3, and on both sides, there are locking bumps 15 that are stopped by either one of the locking positions 6. The components are integrally molded, and below the slide member 5, a fixed fastener 8 is provided that passes through a guide groove 4 and the strap body 9. The fixed fastener 8 is a snap-fit ​​made of high-strength engineering plastic material (e.g., glass fiber reinforced polyoxymethylene). One end of the strap body 9 is attached to the bracket body 1, and the other end is attached to the slide member 5. An initial locking position 7 is further opened at one end of the chute 3, and when the locking bump 15 is located within the initial locking position 7, the strap body 9 is under tension. Both the initial locking position 7 and the locked locking position 6 are provided with POM plastic ball blocks that are locked by the locking bump 15. By opening a locking position 6 on the side and aligning it with the locking bumps 15 on both sides of the sliding member 5, the sliding member 5 moves along the chute 3 and, after being adjusted to different positions, achieves a stable lock, allowing for convenient adjustment of the degree of slack in the strap body 9 to adapt to different usage needs. On the other hand, setting the initial locking position 7 provides the strap body 9 with a reference tension state, making it easy for the user to quickly return to the initial usage position. Most importantly, the POM plastic ball blocks installed within the initial locking position 7 and each lock locking position 6 utilize their own good elasticity and wear resistance characteristics. When the locking bump 15 is engaged, the ball block can generate appropriate elastic deformation to achieve reliable locking. Moreover, in multiple engagement and separation processes, the POM plastic material can effectively reduce the wear on the locking bump 15 and the inner wall of the locking position. Meanwhile, by utilizing the lock locking position 6 where the thickness of the side is much greater than that of the bottom support portion, the wear originally concentrated on the bottom support portion is transferred to the side lock locking position 6. Since the thickness of the side where the lock locking position 6 is located is greater, its structural strength and wear resistance performance are significantly superior to those of the original bottom support portion. Even under the long-term repeated locking friction of the locking bump 15, the wear rate can be effectively slowed down, avoiding the invalidation of the support structure due to local excessive wear, thereby greatly reducing the damage risk of the entire bracket and significantly extending the service life of the bracket.

[0022] Here, the two lock locking positions 6 include a first-stage locking position and a second-stage locking position located on the side away from the slide member 5 of the first-stage locking position, and can adapt to objects of different sizes or thicknesses. When it is necessary to fix an object with a relatively small size, the slide member 5 can be moved to the first-stage locking position closer to the initial locking position 7. At this time, the tightening degree of the strap body 9 is relatively high, and a stronger restraining force can be provided. However, for an object with a relatively large size, the slide member 5 can be adjusted to the second-stage locking position away from the initial locking position 7 to maintain an appropriate tension in the strap body 9, avoiding deformation of the object due to over-tightening or instability of the fixation due to excessive loosening. The multi-stage adjustment design extremely enhances the versatility and compatibility range of the strap bracket, and can meet various fixing requirements.

[0023] Furthermore, retractable openings 12 are provided at both ends of the slide member 5, and connecting portions 14 are formed at both ends of the slide member 5 with locking bumps 15 attached. The connecting portions 14 may be straight. The design of the linear connection section 14, while guaranteeing structural strength compared to conventional arc-shaped or bent structures, effectively reduces material usage and production costs, and allows the force-receiving direction of the locking bump 15 to be more direct, thus avoiding the problem of reduced engagement accuracy between the locking bump 15 and the locked position 6 or initial locking position 7 due to deformation of the connection section 14. On the other hand, the opening of the retraction port 12 provides the necessary elastic deformation space when the connecting portion 14 engages with or disengages from the locking bump 15, thereby allowing the connecting portion 14 to generate a small elastic retraction when the locking bump 15 interacts with the POM plastic ball block, ensuring smooth engagement, avoiding potential component damage due to rigid collision, and further enhancing the feel and service life during the slide adjustment process.

[0024] The connecting portion 14 may be "M" shaped, and an arc-shaped elastic plate 16 is attached to one side of the escape opening 12, with one end fixed to the escape opening 12. The "M"-shaped connector 14, with its unique bending structure, can generate a more favorable elastic cushioning effect when the locking bump 15 is subjected to force. Compared to the straight connector 14, its deformation capacity is stronger, and by further absorbing impact forces during the engagement and disengagement processes, it can more effectively protect the locking bump 15 and the POM plastic ball block, reducing wear. On the other hand, the arc-shaped elastic plate 16, which is bonded to one side of the retraction opening 12 and has one end fixed to the retraction opening 12, can assist and reinforce the elastic deformation of the "M"-shaped connecting portion 14. When the connecting portion 14 deforms due to the movement of the locking bump 15, the arc-shaped elastic plate 16 bends accordingly, and its own elastic recovery force reacts to the connecting portion 14, thereby improving the reset speed and stability of the connecting portion 14 and ensuring accuracy and smoothness when the locking bump 15 switches between different locking positions. At the same time, the arc-shaped elastic plate 16 can share the stress received by a portion of the connecting portion 14, preventing fatigue damage to the connecting portion 14 due to repeated deformation over a long period of time, and further increasing the structural reliability and service life of the entire sliding member 5.

[0025] Furthermore, a guide groove 4 is drilled through the bottom of the chute 3, and a stopper block 13 that slides within the guide groove 4 is integrally molded to the bottom of the slide member 5. This provides a horizontal stopper during the process of the slide member 5 sliding along the chute 3, ensuring that the force received on both sides of the slide member 5 is uniform. This prevents catching or misalignment between the locking bump 15 and the locked position 6 or initial locking position 7 due to an offset on one side, effectively guaranteeing the stability and accuracy of the slide adjustment.

[0026] The operating principle of this invention is as follows:

[0027] When necessary, the tensioned strap body 9 is loosened by pushing the sliding member 5 to move it to the other end within the chute 3, allowing the arm or handle to pass through the gap between the strap body 9 and the bracket body 1. Then, the sliding member 5 is pushed again to move it to the corresponding locking position 6, at which point the locking bump 15 engages within the current locking position 6, securely locking the sliding member 5. Finally, the mobile phone is placed on the cap 2, and the magnetic ring 11 secures the mobile phone to the bracket, thus providing convenient attachment of the mobile phone. If it is necessary to remove the mobile phone or adjust its position, simply push the sliding member 5 again to allow the locking bump 15 to overcome the elastic force of the POM plastic ball block and disengage from the current locked position 6, and then move the sliding member 5 to the initial locked position 7 or another suitable locked position 6.

[0028] The final points to be explained are as follows: In the description of this application, unless otherwise specified or limited, the terms "attachment," "connection," and "connection" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two elements, or direct connections.
