[0001] This application relates to the field of charging technology, and more particularly to a charging clip. Background Technology

[0002] Charging clips are generally used to charge electronic devices, such as Bluetooth headsets. A charging clip typically includes a cover and the main unit. During charging, the cover is closed to prevent the electronic device from falling out. To remove the device, the cover is opened, and the device is taken out. There are generally two ways to open the cover: one is by rotation, and the other is by spring-loaded pressure.

[0003] In spring-loaded charging clips, the guide for the cover's vertical movement is achieved by an elastic element. This elastic element has a certain degree of elasticity and variability, resulting in poor stability and wobbling during the opening process. This wobbling not only affects the user's operating experience but may also increase friction between the cover and the main unit, thus accelerating the wear and aging of the charging clip. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] In spring-loaded charging clips, the guide for the cover's vertical movement is achieved by an elastic element. This elastic element has a certain degree of elasticity and variability, resulting in poor stability and wobbling during the opening process. This wobbling not only affects the user's operating experience but may also increase friction between the cover and the main unit, thus accelerating the wear and aging of the charging clip.

[0034] To resolve the above technical issues, please refer to Figure 1-3 This application proposes a charging clip, including a main unit 100 and a cover 200.

[0035] Charging clips, as convenient charging devices, are widely used for charging small electronic devices such as Bluetooth headsets. Their structure typically includes a main unit 100 for housing the electronic device and a cover for protecting the charging space. During charging, the cover remains closed to ensure the electronic device is securely placed within the charging clip and to prevent accidental dislodgement. When it is necessary to remove the electronic device, the user can open the cover using a specific mechanism.

[0036] In this embodiment of the application, the lid is opened by a spring-pressing opening method. The spring mechanism is triggered by pressing a certain area on the host 100, causing the lid to pop up automatically.

[0037] The main unit 100 and the cover 200 in the charging clip will be further described below.

[0038] The host 100 is the main body of the charging clip, used to accommodate and fix the electronic device to be charged (such as a Bluetooth headset). In this embodiment of the application, a Bluetooth headset is used as an example for illustration.

[0039] The main unit 100 also has a control module and a power module. The power module includes a battery pack, a charging pin, and a charging interface located on the main unit 100. The charging pin is electrically connected to the battery pack and is used to connect to the Bluetooth headset to charge the Bluetooth headset. The charging interface is electrically connected to the battery pack and is also electrically connected to the connector of an external power source to charge the battery pack, forming a complete charging process.

[0040] The control module is responsible for receiving and processing charging requests from users or electronic devices. It can adjust charging parameters according to the real-time status of the battery to ensure a smooth, efficient and safe charging process.

[0041] The main unit 100 has a guide post 101, and the cover 200 is arranged along the length of the guide post 101, forming a charging space with the main unit 100. This charging space is used to hold the Bluetooth headset, and the charging pins on the main unit 100 extend into the charging space. The cover 200 is elastically and movably connected to the main unit 100 via an elastic member 201. The cover 200 has a sleeve portion 202 located to the side of the elastic member 201. The sleeve portion 202 is sleeved onto the guide post 101 for sliding connection with the main unit 100. During this process, the cover 200 has both a closed and an open state. Please refer to [link / reference needed]. Figure 1 The charging space is exposed in both the closed and open states to allow for the placement of Bluetooth earphones.

[0042] In this embodiment, the elastic element 201 provides elasticity and support. When the cover 200 is in the closed state, the elastic element 201 is compressed. When the cover 200 switches from the closed state to the open state, the elastic element 201 releases its elasticity, ensuring that the cover 200 opens automatically. During this process, due to the sliding connection between the sleeve 202 and the guide post 101, the stability of the cover 200 during opening and closing is significantly improved, reducing the shaking of the cover 200 and the friction between it and the host 100, and extending the service life of the charging clip.

[0043] In some embodiments, the guide post 101 is a metal guide post. The metal guide post is precision-machined and processed to provide high precision and stability, ensuring the accuracy and smoothness of the cover 200 during sliding, and reducing shaking and friction. Metal guide posts typically have good wear resistance, resisting wear during long-term use and extending the service life of the charging clip.

[0044] In addition, the metal guide post has high strength and load-bearing capacity, which can support the weight of the cover 200 and withstand external pressure, ensuring the stability and safety of the charging clip during use.

[0045] The metal guide post can be a stainless steel guide post, a bearing steel guide post, a cemented carbide guide post, etc., and there is no limitation. In the embodiments of this application, a stainless steel guide post is preferred. Stainless steel guide posts have excellent corrosion resistance and wear resistance, and the material is readily available.

[0046] Please see Figure 3 In one embodiment of this application, the guide post 101 and the host 100 are integrally formed. The integral forming of the guide post 101 and the host 100 eliminates the connection gap between the two, thereby significantly enhancing the overall structural strength of the charging clip. In addition, the integral forming technology simplifies the manufacturing process of the charging clip and reduces the assembly steps and required fasteners.

[0047] It should be understood that when the guide post 101 is a metal guide post 101 and the main body 100 housing is made of plastic, during the one-piece molding process, when the main body 100 housing is in a molten state, the metal guide post 101 is placed inside the molten housing and then formed.

[0048] To further increase the stability of the connection between the guide post 101 and the host 100, in this embodiment, the outer wall of the guide post 101 has a groove 101a, the host 100 has a mounting groove 100a, the inner wall of the mounting groove 100a has a protrusion 100b, a portion of the guide post 101 is located in the mounting groove 100a, and the protrusion 100b is engaged in the groove 101a. In this way, the guide post 101 is difficult to separate from the host 100.

[0049] In order to make the entire host 100 lightweight, in one embodiment of this application, the host 100 is provided with a protrusion 102, the protrusion 102 forms a mounting groove 100a, and the outer side wall of the protrusion 102 is provided with a reinforcing rib 103.

[0050] By providing a protrusion 102 on the main unit 100 and using the protrusion 102 to form a mounting groove 100a, the amount of material required for the overall structure can be effectively reduced, the volume and space occupied by the overall structure can be reduced, thereby saving material costs.

[0051] Meanwhile, the addition of stiffeners 103 can significantly improve the structural strength of the protrusion 102 without adding too much material, achieving efficient material utilization. In addition, the addition of stiffeners 103 can optimize the stress distribution on the protrusion 102, reduce stress concentration, help reduce the deformation of the protrusion 102 under stress, and improve the overall fatigue resistance.

[0052] In one embodiment of this application, the protrusion 102 and the host 100 are also integrally molded, which increases the stability of the connection between the protrusion 102 and the host 100.

[0053] Please see Figure 3 In one embodiment of this application, the host 100 has a positioning groove 100d, and the guide post 101 has a first end and a second end. The first end can be connected to the host 100 by injection molding, screw connection, or other fixed connection methods in the prior art. The second end is inserted into the positioning groove 100d and is interference-fitted with the inner sidewall of the positioning groove 100d.

[0054] The first end of the guide post 101 is connected to the main unit 100 by injection molding. This connection method can provide a strong bonding force and ensure that the connection between the guide post 101 and the main unit 100 is stable and reliable. The interference fit between the second end and the positioning groove 100d further enhances the strength of the connection, making the guide post 101 less likely to loosen or fall off when subjected to force.

[0055] The design of the positioning groove 100d provides a clear installation position for the guide post 101, ensuring the accurate positioning of the guide post 101 on the host 100. The interference fit makes the gap between the guide post 101 and the positioning groove 100d extremely small, thereby improving the overall positioning accuracy and stability. In addition, the second end of the guide post 101 is directly inserted into the positioning groove 100d, without the need for additional fasteners or connectors, simplifying the assembly process.

[0056] In another embodiment of this application, please refer to Figure 3-4 A flexible pad 101b is fitted onto the guide post 101, and the flexible pad 101b is located above the socket 202. The presence of the flexible pad 101b provides a shock-absorbing buffer layer between the guide post 101 and the socket 202. When the charging clip is in operation, especially when the cover 200 switches from a closed state to an open state, the socket 202 may directly impact the main unit 100 under the elastic force, which can easily cause wear and damage. However, by setting the flexible pad 101b above the socket 202, the flexible pad 101b can effectively absorb the impact force from the socket 202, reduce the impact of vibration on the overall structure, and thus improve the stability and service life of the charging clip.

[0057] The flexible pad 101b can be made of rubber, silicone or other flexible materials in the prior art, without limitation. Optionally, the flexible pad 101b can be fixed on the host 100 to reduce the friction between the flexible pad 101b and the guide post 101.

[0058] The shock absorption and cushioning effect of the flexible pad 101b can also effectively reduce the noise generated by the socket 202 when it is impacted, which is conducive to improving the quiet performance of the charging clip. At the same time, it can also reduce the shaking of some electrical components inside the host 100 and improve the service life of the entire charging clip.

[0059] Please see Figure 3-5 In one embodiment of this application, the host 100 is provided with a mounting post 104, and the elastic element 201 includes a compression spring, which is sleeved on the mounting post 104, and the two ends of the compression spring are respectively connected to the sleeve part 202 and the host 100.

[0060] When the cover 200 is in the closed state, the compression spring is in the compressed state. When the cover 200 switches from the closed state to the open state, the compression spring releases the pressure, allowing the cover 200 to quickly switch to the open state. As an elastic element 201, the compression spring can effectively provide stable elastic support between the sleeve 202 and the main unit 100, ensuring that the sleeve 202 can evenly distribute pressure when subjected to force, reducing local wear, and can also absorb and buffer vibrations to a certain extent, improving the stability and durability of the entire system.

[0061] When the compression spring wears out or fails due to prolonged use, it can be easily removed and replaced by the user due to its simple sleeve structure with the mounting post 104, without the need for complicated disassembly work, which greatly reduces the difficulty and cost of maintenance.

[0062] The mounting post 104 can also be integrated with the host 100, thereby improving the stability of the connection between the mounting post 104 and the host 100.

[0063] In one embodiment of this application, please refer to Figure 6-7 The charging clip also includes a first locking component 310 and a second locking component 320.

[0064] The first locking assembly 310 includes a limiting frame 311. The limiting frame 311 has two sidewalls spaced apart along the movement direction of the first locking assembly 310. These are a first sidewall and a second sidewall. The sidewall adjacent to the host 100 is the first sidewall 311a, and the other sidewall relatively far from the host 100 is the second sidewall. The second sidewall is provided with a first locking member 312, which enables the entire first locking assembly 310 to be a press-driven type.

[0065] The second locking assembly 320 includes a connecting rod 321 and a second locking member 322. Along the direction of movement of the first locking assembly 310, the second locking member 322 is located on the side of the connecting rod 321 facing the first locking member 312.

[0066] When the cover 200 is in the closed position and the first locking component 310 is in the locked position, the second locking component 322 is located below the first locking component 312 and abuts against the first locking component 312 to restrict the cover 200 from switching from the closed position to the open position. When the first locking component 310 is in the unlocked position, the first locking component 312 and the second locking component 322 are separated.

[0067] When the cover 200 needs to be closed, press the cover 200 so that the second locking member 322 extends into the limiting frame 311 and is located below the first locking member 312 (at this time, the first locking member 312 and the second locking member 322 are misaligned). Then move the first locking component 310 so that the second locking member 322 is located directly below the first locking member 312 and abuts against the first locking member 312. In this way, under the limiting action of the first locking member 312, the cover 200 is difficult to open. Only by moving the first locking component 310 to separate the first locking member 312 from the second locking member 322, and the second locking member 322 is unrestricted, can the cover 200 move upward and be in the open state. The entire locking and unlocking process is simple and quick, improving the efficiency of operation.

[0068] To facilitate quick switching of the lid 200 between the closed and open positions, in one embodiment of this application, please refer to... Figure 7 The cover 200 is elastically and movably connected to the host 100, and the first locking component 310 can also be elastically and movably connected to the host 100. Specifically, the elasticity is achieved by setting a spring, wherein the first locking component 310 is a first spring 331, and the spring located on the cover 200 is a second spring 105 (i.e., the elastic element 201 in the embodiment of this application).

[0069] When the cover 200 is in the closed position, the second spring 102 is under pressure. When the first locking member 312 and the second locking member 322 are separated, the second spring 102 releases its elastic force, so that the cover 200 automatically switches from the closed position to the open position, thereby improving the opening efficiency.

[0070] When the first locking component 310 is in the locked position, the first spring 331 is in a free state. When the first locking component 310 is pressed, the first spring 331 is in a compressed state. When the first locking component 310 is released, the first locking component 310 resets under the elastic force of the first spring 331. The first locking component 310 can be accurately reset without manual pulling.

[0071] Thus, during the pressing of the cover 200, the process of the user manually pressing the first locking component 310 is reduced, improving the closing efficiency.

[0072] Furthermore, with the cover 200 elastically connected to the main unit 100 and the first locking assembly 310 also elastically connected to the main unit 100, after the first locking member 312 moves to avoid the second locking member 322, under the reset action of the first spring 331, the first locking member 312 can directly reset to the locked position. Since the cover 200 is in a pressed state, the second spring 102 is also in a compressed state. The first locking member 312 and the second locking member 322 elastically abut against each other. Through the elastic force of the second spring 102, the firmness and stability of the first locking member 312 and the second locking member 322 can be increased, making it difficult for the first locking member 312 and the second locking member 322 to move.

[0073] Please see Figure 3 In one embodiment of this application, the host 100 includes a base 110 and a middle frame 120. The middle frame 120 is disposed above the base 110 and is snapped into the base 110. The middle frame 120 and the base 110 enclose each other to form an installation cavity 100c. The guide post 101 and the sleeve part 202 are both disposed in the installation cavity 100c.

[0074] The mounting cavity 100c is a closed space. The guide post 101, power module and control module can all be set in the closed space, which can effectively prevent external factors such as dust and moisture from corroding the internal components and extend the service life of the host 100. Since dust and other impurities are difficult to adhere to the guide post 101, the smoothness of the sliding of the socket 202 on the guide post 101 can also be guaranteed.

[0075] It is understood that the detachable design of the base 110 and the middle frame 120 allows users to easily install the corresponding electrical components on the base 110 and the middle frame 120 before finally assembling the base 110 and the middle frame 120. The guide post 101 can be installed on the base 110, the middle frame 120, or both. In this embodiment, the guide post 101 is exemplarily installed on both the base 110 and the middle frame 120.

[0076] The guide post 101 can be integrally formed and connected with the middle frame 120. Correspondingly, a positioning groove 100d can be provided on the base 110. There can be one or more positioning grooves 100d. In this way, when the middle frame 120 and the base 110 are installed, the guide post 101 can be inserted into the positioning groove 100d to play a certain positioning and guiding role. Secondly, the positioning groove 100d can also play a certain stabilizing role for the guide post 101.

[0077] In one embodiment, in order to further increase the stability when the base 110 is connected to the middle frame 120, the base 110 is provided with at least two spaced limiting grooves 110a, and the middle frame 120 is provided with limiting rods 121 corresponding to the number of limiting grooves 110a. When the base 110 and the middle frame 120 are engaged, the limiting rods 121 are inserted into the limiting grooves 110a.

[0078] The limiting groove 110a can be two, three, four, five, etc., and there is no limitation here. In one embodiment of this application, two limiting grooves 110a are used for illustrative purposes.

[0079] Two protruding posts are provided on the base 110, and a limiting groove 110a is formed in the middle of the protruding posts. The two protruding posts are staggered from the guide post 101, which can increase the stability of the connection between the base 110 and the middle frame 120. On the other hand, when the base 110 and the middle frame 120 are finally assembled, the limiting frame can be aligned with the limiting groove 110a to ensure proper installation.

[0080] Please see Figure 5In one embodiment of this application, the sleeve portion 202 is located below the cover 200, and the sleeve portion 202 and the cover 200 are fixedly connected by a connector. Since the sleeve portion 202 and the guide post 101 are both located in the mounting cavity 100c, and for the convenience of assembling the entire charging clip, the base 110, the middle frame 120 and the cover 200 are all separate structures. During assembly, the middle frame 120 and the cover 200 are first placed in a preset position, then the sleeve portion 202 is sleeved on the guide post 101, and the sleeve portion 202 is connected to the cover 200 by the connector. Finally, the middle frame 120 and the base 110 are snapped together to complete the snapping of the cover 200, the middle frame 120 and the base 110. In this way, the guide post 101 and the sleeve portion 202 are both located in the mounting cavity 100c, reducing the interference of dust and other impurities, and ensuring the smooth sliding of the sleeve portion 202 on the guide post 101.

[0081] The connection via connectors (such as screws, clips, etc.) facilitates quick fixing and disassembly, which is beneficial for daily maintenance and replacement of parts. For example, the cover 200 can be quickly removed from the middle frame 120, making it convenient for the inspection and replacement of various parts.
