[0042] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0043] In the spring-pressed open charging clip, the cover body is in a matching state through the locking of the lock catch mechanism, and then the lock catch mechanism is unlocked, so that the cover body can move relative to the host to open the cover body. However, in the related art, when the cover body is opened relative to the host, it is easy to shake, which increases the friction between the cover and the host, thereby accelerating the wear and aging of the charging clip.

[0044] To solve the above problems, please refer toFigures 1-3 The embodiment of the present application provides a charging clamp, which comprises a host 100, a cover 200, a locking mechanism 300 and a guide column 101.

[0045] The charging clamp is a convenient charging device and is widely applied to charging small electronic devices such as Bluetooth earphones. The structure of the charging clamp usually comprises a host 100 part for accommodating the electronic device and a cover for protecting the charging space. During the charging process, the cover remains in a closed state to ensure that the electronic device is stably placed in the charging clamp and is prevented from being accidentally dropped. When the electronic device needs to be taken out, a user can open the cover through a specific mechanism.

[0046] In the embodiment of the present application, the cover is opened through a spring pressing type opening mode. The spring mechanism can be triggered by pressing a certain area on the host 100, so that the cover is automatically popped up.

[0047] The host 100, the cover 200, the locking mechanism 300 and the guide column 101 in the charging clamp will be further described below.

[0048] The host 100 is the main part of the charging clamp and is used for accommodating and fixing the electronic device (such as a Bluetooth earphone) to be charged. In the embodiment of the present application, the electronic device is exemplarily taken as a Bluetooth earphone.

[0049] The host 100 further has a control module and a power module. The power module comprises a battery pack, a charging pin and a charging interface in the host 100. The charging pin is electrically connected with the battery pack and is used for being connected with the Bluetooth earphone to charge the Bluetooth earphone. The charging interface is electrically connected with the battery pack and is electrically connected with the joint of the external power supply to charge the battery pack, thereby forming a complete charging process.

[0050] The control module is responsible for receiving and processing the charging request from the user or the electronic device and can adjust the charging parameter according to the real-time state of the battery, so as to ensure that the charging process is stable, efficient and safe.

[0051] The host 100 is provided with the guide column 101, the cover 200 is arranged along the length direction of the guide column 101 and forms a charging space with the host 100. The charging space is used for placing the Bluetooth earphone, the charging pin on the host 100 extends into the charging space, the cover 200 is elastically movably connected to the host 100 through an elastic element, the cover 200 has a sleeve part 201 which is located at the side of the elastic element and is sleeved with the guide column 101 to be slidably connected with the host 100. During the process, the cover 200 has a closed state and an open state. Please refer to Figure 1In the closed state and the open state, the charging space is exposed for placing the Bluetooth earphone, wherein the cover 200 is in the closed position relative to the main machine 100 when the cover 200 is in the closed state, and the cover 200 is in the open position relative to the main machine 100 when the cover 200 is in the open position.

[0052] Please refer to Figures 3-4 The locking mechanism 300 comprises a first locking assembly 310 and a second locking assembly 320, the first locking assembly 310 is movably connected to the main machine 100, and the second locking assembly 320 is arranged on the cover 200. The first locking assembly 310 has a locking position and an unlocking position relative to the main machine 100. When the cover 200 is in the closed position and the first locking assembly 310 is in the locking position, the first locking assembly 310 and the second locking assembly 320 can be limited to move relative to each other. When the first locking assembly 310 is in the unlocking position, the cover 200 can be switched between the closed position and the open position.

[0053] That is, by adjusting the first locking assembly 310 between the locking position and the unlocking position, the cover 200 can be switched between the closed position and the open position, facilitating charging of the Bluetooth earphone and taking out the earphone after charging is completed.

[0054] In addition, please refer to Figures 5-6 The guide column 101 is arranged on the main machine 100 to provide guiding and supporting effects for the sleeve part 201 of the cover 200. When the cover 200 is switched between the closed position and the open position, the sleeve part 201 slides along the guide column 101, avoiding shaking of the cover 200 relative to the main machine 100 when the cover 200 is switched between the closed position and the open position, and ensuring smoothness and accuracy of movement of the cover 200.

[0055] In an embodiment of the present application, the main machine 100 is formed with a mounting cavity 100a, a through hole 100b communicating with the mounting cavity 100a is arranged on the side wall of the main machine 100, and the first locking assembly 310 is movably arranged in the through hole 100b. By arranging the through hole 100b on the side wall of the main machine 100 and movably arranging the first locking assembly 310 in the through hole 100b, the first locking assembly 310 occupies less additional space, and the entire charging clip structure is more compact, facilitating miniaturized design of the entire charging clip and facilitating carrying and use.

[0056] The first locking assembly 310 is located in the through hole 100b, and a user can trigger the locking or unlocking function through simple operations (such as pressing, pulling, etc.), so that the cover 200 can be closed and opened more intuitively and conveniently, and the user can complete locking and unlocking of the cover 200 without complex actions.

[0057] In addition, the through hole 100b can also serve as a guide, thereby limiting the movement path of the first locking assembly 310, making it easier for the first locking assembly 310 to move along the path between the locked and unlocked positions, and difficult to move to other positions, ensuring the stability and smoothness of the cover 200 during closing and opening.

[0058] Based on the previous embodiment, the first locking assembly 310 can be moved by pressing or pulling, etc. In order to improve the sealing of the first locking assembly 310 and the main machine 100, in the present embodiment, the charging clip further comprises a resilient sealing ring 400, which is elastically pressed between the pressing wall surface 310a and the supporting wall surface 100c.

[0059] The supporting wall surface 100c can be formed on the side of the hole wall surface of the through hole 100b facing the installation cavity 100a, or it can also be formed on the side of the hole wall surface of the through hole 100b facing outside the installation cavity 100a. When the supporting wall surface 100c faces the installation cavity 100a, the corresponding first locking assembly 310 is a pressing type movement. When the supporting wall surface 100c faces outside the installation cavity 100a, the corresponding first locking assembly 310 is a pulling type movement. In the present embodiment, the first locking assembly 310 is described as an example of pressing type movement.

[0060] The resilient sealing ring 400 is arranged between the pressing wall surface 310a and the supporting wall surface 100c, forming an effective sealing barrier. This can prevent dust, moisture or other impurities from entering the installation cavity 100a through the through hole 100b, thereby protecting the internal electronic components and Bluetooth earphone from damage.

[0061] In addition, the resilient sealing ring 400 not only provides a sealing function, but also plays a buffering and lubricating role during the movement of the first locking assembly 310. It reduces the direct friction between the pressing wall surface 310a and the supporting wall surface 100c, and can also reduce the vibration caused by direct impact, prolonging the service life of the first locking assembly 310 and the main machine 100, and ensuring smooth operation of the locking mechanism.

[0062] Because the resilient sealing ring 400 exerts a certain pressure on the pressing wall surface 310a and the supporting wall surface 100c, it can enhance the stability of the first locking assembly 310 in the through hole 100b. Even under the influence of external vibration or impact, the locking assembly can maintain its position and is not easy to loosen or fall off.

[0063] The elastic sealing ring 400 is usually made of wear-resistant and corrosion-resistant materials, such as rubber or silicone, and the like. The selection of the above-mentioned materials enables the sealing ring to maintain good elasticity and sealing performance for a long time, thereby improving the durability of the entire charging clamp. The elastic sealing ring 400 can be connected to the main machine 100 or the first locking assembly 310 in a glued manner, and in order to increase the stability of the elastic sealing ring 400 during use, a groove can also be formed on the support wall surface 100c or the extrusion wall surface 310a, so that part of the circumferential side surface of the elastic sealing ring 400 is attached to the inner wall of the groove.

[0064] In an embodiment of the present application, the main machine 100 includes a base 110 and a middle frame 120, the middle frame 120 is arranged above the base 110 and is clamped with the base 110, the middle frame 120 and the base 110 enclose and form a mounting cavity 100a, and part of the guide column 101 and the lock catch mechanism 300 are arranged in the mounting cavity 100a.

[0065] The mounting cavity 100a is a closed space, and the guide column 101, the power module and the control module can be arranged in the closed space, which can effectively prevent external factors such as dust and moisture from corroding the internal components, thereby prolonging the service life of the main machine 100. Since dust and other impurities are difficult to adhere to the guide column 101, the smoothness of the sleeve connection part 201 sliding on the guide column 101 can also be ensured.

[0066] It can be understood that through the detachable arrangement of the base 110 and the middle frame 120, the user can first install the corresponding electrical components on the base 110 and the middle frame 120, and then finally complete the assembly of the base 110 and the middle frame 120. The guide column 101 can be installed on the base 110, or on the middle frame 120, or on both the base 110 and the middle frame 120. In the embodiment of the present application, the guide column 101 is installed on the base 110 and the middle frame 120 for exemplary description.

[0067] Please refer to Figure 4 In an embodiment of the present application, the first locking assembly 310 and the second locking assembly 320 are further described.

[0068] The first locking assembly 310 includes a limiting frame 311 having two side walls arranged at intervals along the movement direction of the first locking assembly 310, and one of the two side walls is provided with a first locking piece 312. The second locking assembly 320 includes a connecting rod 321 and a second locking piece 322, and along the movement direction of the first locking assembly 310, the second locking piece 322 is located on the side of the connecting rod 321 facing the first locking piece 312.

[0069] 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.

[0070] 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.

[0071] It should be understood that one of the two sidewalls of the limiting frame 311 is located near the sidewall of the host 100, which is the first sidewall 311a, and the other sidewall is located relatively far away from the sidewall of the host 100, which is the second sidewall 311b. When the first locking member 312 is located on the first sidewall 311a, the first locking component 310 needs to be pulled out of the mounting cavity 100a to avoid the second locking member 322. When the first locking member 312 is located on the second sidewall 311b, the first locking component 310 needs to be pushed into the mounting cavity 100a to avoid the second locking member 322. That is, it is a pressing type. Considering that the pressing type occupies less space outside the mounting cavity 100a, making the entire charging clip structure compact and easy to miniaturize, in this embodiment, the first locking member 312 is located on the second sidewall 311b.

[0072] To facilitate quick switching of the lid 200 between the closed and open positions, in one embodiment of this application, please refer to... Figures 4-6 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 springs, wherein the first locking component 310 has a first spring 331, and the spring located on the cover 200 is a second spring 103.

[0073] That is, when the cover body 200 is in the closed position, the second spring 103 is in the compressed state, when the first locking member 312 is separated from the second locking member 322, the second spring 103 releases the elastic force, so that the cover body 200 automatically switches from the closed position to the open position, improving the opening efficiency.

[0074] When the first locking assembly 310 is in the locked position, the first spring 331 is in the free state, when the first locking assembly 310 is pressed, the first spring 331 is in the extrusion state, and when the first locking assembly 310 is released, the first locking assembly 310 is reset under the action of the elastic force of the first spring 331, without manual pulling, the precise reset of the first locking assembly 310 can be realized.

[0075] In an embodiment of the present application, please refer to Figure 4 The first locking member 312 has a first guide surface 321a, which has a first end facing the cover body 200 and a second end away from the cover body 200 in the vertical direction, and the distance between the first guide surface 321a and the side wall where the first locking member 312 is located gradually increases from the first end to the second end. The second locking member 322 has a second guide surface 322a, which has a first side facing the limiting frame 311 and a second side away from the limiting frame 311 in the vertical direction, and the distance between the second guide surface 322a and the connecting rod 321 gradually increases from the first side to the second side.

[0076] The first guide surface 321a and the second guide surface 322a can be arc surfaces or inclined surfaces, and at least part of the first guide surface 321a and the second guide surface 322a overlap in the vertical direction when the first locking assembly 310 is in the locked position. In this way, when the cover body 200 is pressed to switch from the open position to the closed position, the first guide surface 321a can contact the second guide surface 322a and push the movement of the first locking member 312 to avoid the second locking member 322, and when the second locking member 322 moves below the first locking member 312, the first locking member 312 is reset.

[0077] In this way, during the pressing process of the cover body 200, the process of manually pressing the first locking assembly 310 by the user is reduced, and the closing efficiency is improved.

[0078] In addition, when the cover 200 is elastically movably connected to the main machine 100, the first locking assembly 310 can also be elastically movably connected to the main machine 100, and after the first locking piece 312 moves to avoid the second locking piece 322, under the first elastic reset action, the first locking piece 312 can be directly reset to the locked position, and the cover 200 is in the pressed state, the second spring 103 is also in the extruded state, the first locking piece 312 and the second locking piece 322 are elastically abutted, and through the elastic force of the second spring 103, the firmness and stability of the first locking piece 312 and the second locking piece 322 can also be increased, so that the first locking piece 312 and the second locking piece 322 are difficult to move.

[0079] Please refer to Figure 4 and Figure 7 In an embodiment of the present application, the main machine 100 is also provided with a guide piece 500, the guide piece 500 is provided with a guide groove 500a, and the first locking assembly 310 further includes a guide rod 330, which is inserted into the guide groove 500a.

[0080] Through the setting of the guide rod 330, the guide rod 330 can play a certain guiding role, thereby limiting the movement path of the first locking assembly 310, so that the first locking assembly 310 is more easily moved on the path of the locked position and the unlocked position, and is difficult to move to other positions, thereby reducing the operation errors caused by shaking or mispositioning. The design of the guide groove 500a can help to accurately position the locking position, so that the locking assembly can accurately reach the locked or unlocked state, thereby improving the overall reliability and accuracy.

[0081] The cooperation of the guide rod 330 and the guide groove 500a can reduce the friction and collision of the first locking assembly 310 to other components in the main machine 100 during operation, thereby prolonging the service life of the first locking assembly 310 and the overall main machine 100.

[0082] Further, please continue to refer to Figures 7-8 The bottom of the guide groove 500a forms a limiting surface, when the first locking assembly 310 moves to the guide rod 330 in contact with the limiting surface along the first direction, the guide piece 500 prevents the guide rod 330 from moving along the first direction, and the contact between the guide rod 330 and the limiting surface limits the further movement of the locking assembly, thereby avoiding damage or wear caused by excessive movement.

[0083] When the guide rod 330 is in contact with the limiting surface, it can serve as a clear indication that the first locking assembly 310 has reached the maximum position, thereby avoiding excessive force from the user, which may damage the first locking assembly 310 or other electrical elements in the installation cavity 100a.

[0084] It needs to be understood that when the first locking assembly 310 is elastically movably connected to the main machine 100, the first spring 331 can be sleeved on the guide rod 330, one end of the first spring 331 is connected to the first locking assembly 310, and the other end of the elastic member is connected to the guide piece 500. The first spring 331 can store and release energy, and when the first locking assembly 310 is pressed, the spring can provide the necessary elastic force to assist in completing the locking or unlocking action, ensuring the reliability and consistency of the locking mechanism.

[0085] The elastic force of the first spring 331 can stabilize the position of the first locking piece 312, so that the first locking piece 312 and the second locking piece 322 are difficult to move when locked, thereby improving the firmness and stability of the locking.

[0086] When the second locking assembly 320 is elastically movably connected to the main machine 100, the mounting rod 102 can be arranged on the main machine 100, and the second spring 103 is sleeved on the mounting rod 102, so that one end of the second spring 103 is connected to the main machine 100, and the other end of the second spring 103 is connected to the cover body 200. That is, when the cover body 200 is in the closed cover position, the second spring 103 is in a compressed state, and when the first locking piece 312 and the second locking piece 322 are separated, the second spring 103 releases the elastic force, so that the cover body 200 automatically switches from the closed cover position to the open cover position, improving the opening efficiency.

[0087] In addition, when the cover body 200 is in the closed cover position and the first locking assembly 310 is in the locked position, the first locking piece 312 and the second locking piece 322 abut, and the elastic force of the second spring 103 can also increase the firmness and stability of the first locking piece 312 and the second locking piece 322, so that the first locking piece 312 and the second locking piece 322 are difficult to move.
