Description

Technical Field

[0001] This utility model relates to the technical field of charging cable connection structure, specifically a detachable elastic buckle structure for charging cables and a power supply device for electronic devices. Background Technology

[0002] Currently, chargers and power banks generally come with a fixed, non-removable charging cable, primarily because the internal structure of the cable is a snap-on design. This structure has significant drawbacks: the charging cable must be carried with the device during use. Even if the user wants to replace it with another compatible cable, the original cable remains attached to the device, taking up space, affecting ease of use, and reducing the overall user experience. Furthermore, since the charging cable is integrated with the power bank and cannot be detached, it is difficult to replace if the cable is damaged, requiring the entire power bank to be disassembled and replaced, resulting in high repair costs. Utility Model Content

[0003] To address the issue that the charging cables of existing chargers and power banks are fixed and cannot be detached, a detachable elastic buckle structure for the charging cable is provided. This structure is simple and easy to operate, enabling quick locking and unlocking of the charging cable, facilitating maintenance and replacement, and improving the flexibility of use.

[0004] The technical solution of this utility model:

[0005] This utility model provides a detachable elastic buckle structure for charging cables, including a housing, a buckle component, an elastic element, and a power connector. The buckle component includes a sliding part, a locking part, and an operating part. The sliding part is reciprocally slidably mounted on the housing. The locking part and the operating part are respectively connected to both ends of the sliding part. The operating part extends outside the housing for pressing to drive the sliding part to slide. The elastic element is installed inside the housing, and its two ends abut against the housing and the sliding part to provide elastic restoring force. The power connector is used to connect the charging cable, and the power connector has a slot adapted to the locking part. The locking part can be inserted into the slot under the action of the elastic element to fix the power connector. An external force drives the operating part to drive the locking part to compress the elastic element, causing the locking part to disengage from the slot and remove the power connector.

[0006] According to one embodiment of the present invention, the inner wall of the housing is provided with two limiting slide plates adapted to the width of the sliding part, and the sliding part is slidably disposed between the two limiting slide plates.

[0007] According to one embodiment of the present invention, a fixing plate is also included, the sliding part is installed in the housing through the fixing plate, and the sliding part is slidably clamped between the housing and the fixing plate.

[0008] According to one embodiment of the present invention, a fixing hole is provided on the fixing plate, and a fixing post is provided on the housing corresponding to the fixing hole. The housing also includes a screw, which passes through the fixing hole and is screwed into the screw hole of the fixing post to fix the fixing plate and the housing.

[0009] According to one embodiment of the present invention, slide rails are provided on both sides of the sliding part, and the slide rails on both sides are slidably engaged with the housing and the fixing plate respectively.

[0010] According to one embodiment of the present invention, the fastener further includes a guide post connected to the sliding part, and the inner wall of the housing is provided with a retaining part arranged at intervals corresponding to the guide post. The two ends of the elastic member are respectively connected between the guide post and the retaining part.

[0011] According to one embodiment of the present invention, the elastic element is a cylindrical helical spring, and the axial direction of the cylindrical helical spring is consistent with the sliding direction of the locking part.

[0012] According to one embodiment of the present invention, the housing is provided with a sliding hole for the operating part to extend out, and the operating part has a movable space in the sliding hole along the sliding direction of the sliding part.

[0013] According to one embodiment of the present invention, a limiting opening adapted to the power supply connector is formed on the housing, the locking part extends into the limiting opening under the action of the elastic member, and the power supply connector is inserted into the limiting opening and fixed by the locking part.

[0014] This utility model also provides a power supply device for electronic devices, including the detachable elastic buckle structure of the charging cable, wherein the power supply device for electronic devices is a charger or a power bank.

[0015] The detachable elastic buckle structure of this utility model charging cable has the following beneficial effects:

[0016] I. Significantly improves usability and solves the pain points of carrying and changing existing fixed charging cables.

[0017] This utility model achieves a detachable design for the charging cable (connected via a power connector) through a combination structure of "shell + buckle + elastic element": users can quickly unlock the locking part and the slot by pressing the operating part to remove the built-in charging cable according to actual needs; when the built-in charging cable is not needed, it can be stored separately to avoid space occupation and operation interference caused by the cable attached to the device; when other compatible charging cables need to be replaced, the original charging cable can also be directly removed and the new charging cable installed, greatly improving the convenience of use and the adaptability of the scenario.

[0018] II. Reduce maintenance costs and simplify the replacement process after charging cable damage.

[0019] In this invention, the power connector and the locking part are elastically locked through a slot. When the charging cable is damaged, simply press the operating part to disengage the locking part from the slot, and the power connector (and the connected charging cable) can be directly removed for replacement without disassembling the device housing. This significantly reduces the difficulty and cost of maintenance, while also avoiding secondary damage caused by disassembling the device and extending the overall service life of the charger and power bank.

[0020] III. Simple and reliable structure, convenient operation and strong locking stability.

[0021] This utility model consists of only a shell, a buckle (including a sliding part, a locking part, and an operating part), an elastic element, and a power connector. It has few parts, a clear assembly relationship, is easy to mass-produce, and has low manufacturing costs. In operation, simply pressing the operating part that extends out of the shell will drive the sliding part to compress the elastic element and unlock it. After releasing the operating part, the elastic element will provide a restoring force to reset the locking part and embed it into the slot. The entire locking and unlocking process does not require complicated steps and can be operated with one hand. At the same time, the elastic element continuously supports the sliding part to ensure that the locking part is stably embedded in the slot, preventing the cable from falling off due to vibration or accidental contact during charging, thus balancing "disassembly" and "connection stability".

[0022] IV. Highly adaptable and easily integrated into existing equipment, requiring no major modifications to the main structure.

[0023] The elastic buckle structure of this utility model can be directly integrated into the existing housing design of chargers and power banks. Only the sliding mounting position of the buckle and the extension hole of the operating part need to be reserved on the housing. There is no need to modify the core power supply module (such as battery and charging chip) of the device. It is compatible with the existing production process of chargers and power banks, which makes it easy for enterprises to quickly upgrade their products and reduce the cost of technology transfer.

[0024] The preferred embodiments of this utility model and their beneficial effects will be further described in detail in conjunction with specific implementation methods. Attached Figure Description

[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] Please see Figures 1 to 5 This utility model provides a detachable elastic buckle structure for charging cables, including a housing 1, a buckle component 2, an elastic component 3, and a power connector 4. The buckle component 2 includes a sliding part 21, a locking part 22, and an operating part 23. The sliding part 21 is reciprocally slidably mounted on the housing 1. The locking part 22 and the operating part 23 are respectively connected to both ends of the sliding part 21. The operating part 23 extends outside the housing 1 for pressing to slide the sliding part 21. The elastic component 3 is installed inside the housing 1, and its two ends abut against the housing 1 and the sliding part 21 to provide elastic restoring force. The power connector 4 is mounted on the housing 1 for connecting the charging cable. The power connector 4 has a slot 40 adapted to the locking part 22. The locking part 22 can be inserted into the slot 40 under the action of the elastic component 3 to fix the power connector 4. External force drives the operating part 23 to compress the elastic component 3, causing the locking part 22 to disengage from the slot 40, thereby removing the power connector 4.

[0034] The detachable elastic buckle structure of this utility model charging cable has the following beneficial effects:

[0035] I. Significantly improves usability and solves the pain points of carrying and changing existing fixed charging cables.

[0036] This utility model achieves a detachable design for the charging cable (connected via the power connector 4) through the cooperative structure of "shell 1 + buckle 2 + elastic element 3": users can quickly unlock the locking part 22 and the slot 40 by pressing the operation part 23 to remove the built-in charging cable according to actual needs; when the built-in charging cable is not needed, it can be stored separately to avoid space occupation and operation interference caused by the cable attached to the device; when other compatible charging cables need to be replaced, the original charging cable can also be directly removed and the new charging cable installed, which greatly improves the convenience of use and the adaptability of the scenario.

[0037] II. Reduce maintenance costs and simplify the replacement process after charging cable damage.

[0038] In this invention, the power connector 4 and the locking part 22 are elastically locked through the slot 40. When the charging cable is damaged, simply press the operating part 23 to disengage the locking part 22 from the slot 40, and the power connector 4 (and the connected charging cable) can be directly removed for replacement without disassembling the device housing 1. This significantly reduces the difficulty and cost of maintenance, while avoiding secondary damage caused by disassembling the device and extending the overall service life of the charger and power bank.

[0039] III. Simple and reliable structure, convenient operation and strong locking stability.

[0040] This utility model consists of only a housing 1, a buckle 2 (including a sliding part 21, a locking part 22, and an operating part 23), an elastic element 3, and a power connector 4. It has a small number of parts, a clear assembly relationship, is easy to mass-produce, and has low manufacturing costs. In operation, simply pressing the operating part 23 that extends out of the housing 1 will drive the sliding part 21 to drive the locking part 22 to compress the elastic element 3 to unlock. After releasing the operating part 23, the elastic element 3 will provide a restoring force to reset the locking part 22 and embed it into the slot 40. The entire locking and unlocking process does not require complicated steps and can be operated with one hand. At the same time, the elastic element 3 continuously supports the sliding part 21 to ensure that the locking part 22 is stably embedded in the slot 40, preventing the cable from falling off due to vibration or accidental contact during charging, thus taking into account both "disassembly" and "connection stability".

[0041] IV. Highly adaptable and easily integrated into existing equipment, requiring no major modifications to the main structure.

[0042] The elastic buckle structure of this utility model can be directly integrated into the existing housing design of chargers and power banks. Only the sliding mounting position of the buckle 2 and the extension hole of the operating part 23 need to be reserved on the housing 1. There is no need to modify the core power supply module (such as battery or charging chip) of the device. It is compatible with the existing production process of chargers and power banks, which makes it easy for enterprises to quickly upgrade their products and reduce the cost of technology transfer.

[0043] In this embodiment, the inner wall of the housing 1 is provided with two limiting slide plates 11 that are adapted to the width of the sliding part 21. The sliding part 21 is slidably disposed between the two limiting slide plates 11.

[0044] The two limiting slide plates 11 on the inner wall of the housing 1 are precisely matched with the width of the sliding part 21, forming a dedicated sliding guide channel. This restricts the sliding part 21 to make linear reciprocating movements between the two plates, effectively preventing the sliding part 21 from shifting laterally, tilting, or twisting during movement. This design ensures that the locking part 22 always moves along the preset trajectory and can accurately align with the slot 40 of the power connector 4, avoiding problems such as incomplete locking or unlocking due to sliding deviation. At the same time, the close sliding of the sliding part 21 and the limiting slide plates 11 reduces movement resistance, making the pressing of the operating part 23 smoother and without any sticking or obstruction, significantly improving the user's operating experience.

[0045] Two limiting slide plates 11 form a symmetrical limiting on both sides of the sliding part 21, so that when the sliding part 21 is subjected to the holding force of the elastic member 3, the pressing force of the operating part 23, and the contact force of the power connector 4, the force is evenly distributed on both sides of the contact surface, avoiding deformation or wear caused by local stress concentration. Compared with the design without a guide structure, this solution disperses the friction force points by limiting slide plates 11, reducing the direct friction loss between the sliding part 21 and the inner wall of the housing 1, while preventing the locking part 22 from being worn on one side of the slot 40 due to tilting, which greatly extends the service life of core components such as the buckle 2 and the power connector 4, and improves the durability of the entire buckle structure.

[0046] In this embodiment, the detachable elastic buckle structure of the charging cable of this utility model includes a fixing plate 5. The sliding part 21 is installed inside the housing 1 through the fixing plate 5. The sliding part 21 is slidably clamped between the housing 1 and the fixing plate 5.

[0047] The sliding part 21 is clamped between the housing 1 and the fixed plate 5, forming an all-round constraint structure of "upper and lower limit + left and right limit in conjunction with the original two limit slide plates 11", which completely eliminates the possibility of the sliding part 21 moving up and down, shifting laterally or tilting and twisting during movement. This two-way clamping design ensures that the sliding part 21 always slides smoothly along the preset straight trajectory, so that the locking part 22 can be accurately aligned with the slot 40 of the power connector 4, avoiding problems such as insecure locking and incomplete unlocking caused by displacement deviation; at the same time, the clamping fit reduces the gap between the sliding part 21 and the contact surface, so there is no shaking during movement, and the feel is more uniform and smooth when pressing the operating part 23, without any jamming or resistance, further optimizing the user's operating experience.

[0048] The fixing plate 5 and the housing 1 form a stable clamping and mounting structure, providing uniform support for the sliding part 21. This ensures that when the sliding part 21 bears the holding force of the elastic element 3, the pressing force of the operating part 23, and the contact force of the power connector 4, the force is distributed across multiple contact surfaces (up, down, left, and right), effectively preventing deformation, wear, or collapse of the inner wall of the housing 1 caused by localized stress concentration. Compared to a single limiting structure, this solution enhances the installation stability of the sliding part 21 through the clamping action of the fixing plate 5, reduces frictional wear of core components, and avoids unilateral wear of the locking part 22's groove 40 due to uneven force distribution. This significantly extends the service life of the buckle 2 and the power connector 4, improving the long-term reliability of the entire buckle structure.

[0049] In this embodiment, the fixing plate 5 has fixing holes, and the housing 1 has fixing posts at the corresponding fixing hole positions. Screws 6 pass through the fixing holes of the fixing plate 5 and are screwed into the screw holes of the fixing posts. The fixing plate 5 is fixed to the fixing posts of the housing 1 by screws 6 passing through the fixing holes, forming a rigid connection structure. Compared with snap-fit ​​or adhesive fixing methods, screw connections have stronger tightening force, effectively preventing the fixing plate 5 from loosening or shifting due to vibration or frequent operation during long-term use. This design ensures that the clamping gap between the housing 1 and the fixing plate 5 and the sliding part 21 remains uniform and stable, preventing the sliding part 21 from moving up and down or deviating from its sliding trajectory due to loosening of the fixing plate. This further enhances the reliability of the engagement between the locking part 22 and the slot 40 of the power connector 4, preventing the charging cable from accidentally falling off.

[0050] In this embodiment, slide rails 24 are provided on both sides of the sliding part 21, and the two slide rails 24 slide in cooperation with the housing 1 and the fixing plate 5 respectively. The slide rails 24 on both sides of the sliding part 21 form a line contact with the housing 1 and the fixing plate 5, which greatly reduces the contact area and frictional resistance during the sliding process compared with surface contact. When the operating part 23 is pressed, the slide rail can guide the sliding part 21 to slide smoothly along the limiting slide plate 11, avoiding the feeling of jamming and resistance caused by the friction of the contact surface, making the locking and unlocking operation lighter and smoother, and further optimizing the user's hand feel experience.

[0051] In this embodiment, the latching member 2 includes a guide post 25 connected to the sliding part 21. The inner wall of the housing 1 has abutment parts 12 arranged at intervals corresponding to the guide post 25. The elastic member 3 is connected at both ends between the guide post 25 and the abutment parts 12. The guide post 25 and the abutment parts 12 on the inner wall of the housing 1 form a precise corresponding installation position, and the two ends of the elastic member 3 can be directly positioned and connected between the two, completely solving the problem of easy displacement, bending, or detachment of the elastic member when there is no positioning structure. This design fixes the installation position of the elastic member 3, ensuring that it is always in the preset working state, providing stable power support for the locking and resetting of the locking part 22.

[0052] In this embodiment, the elastic element 3 is a cylindrical helical spring, and the axial direction of the cylindrical helical spring is consistent with the sliding direction of the locking part 22. The consistency between the axial direction of the cylindrical helical spring and the sliding direction of the locking part 22 ensures that the spring force is transmitted linearly along the sliding trajectory without any additional lateral force. This design avoids the locking part 22 from shifting or jamming due to lateral forces. Combined with the positioning effect of the guide post 25 and the supporting part 12, this makes the locking part 22's insertion into or release from the slot 40 more precise and effortless, resulting in a more balanced and smooth user experience during pressing.

[0053] In this embodiment, the housing 1 has a sliding hole 10 for the operating part 23 to extend out. The operating part 23 has a movable space within the sliding hole 10 along the sliding direction of the sliding part 21. The sliding hole 10 of the housing 1 is adapted to the operating part 23, and the movable space is set along the sliding direction of the sliding part 21, strictly constraining the operating part 23 to only reciprocate along a preset trajectory, avoiding lateral deviation, twisting, or shaking when pressed. This design ensures that the operating part 23 can accurately drive the sliding part 21 to move synchronously, so that the locking part 22 always inserts into or disengages from the slot 40 in a straight line, eliminating problems such as locking failure and incomplete unlocking caused by displacement of the operating part, and improving the reliability of the action linkage.

[0054] In this embodiment, a limiting opening 13 adapted to the power connector 4 is formed on the housing 1. The locking part 22 extends into the limiting opening 13 under the action of the elastic member 3. The power connector 4 is inserted into the limiting opening 13 and fixed by the locking part 22. The limiting opening 13 of the housing 1 and the power connector 4 are precisely adapted to form a dedicated insertion guide channel. When the power connector 4 is inserted, it can slide smoothly along the inner wall of the limiting opening 13, and can be quickly aligned with the locking part 22 without repeated calibration. At the same time, the locking part 22 is pre-extended into the limiting opening 13 under the action of the elastic member 3. After the power connector 4 is inserted into place, its slot 40 can be immediately aligned with the locking part 22 and lock in place, avoiding locking delay or failure caused by insertion offset, and greatly improving the convenience of charging cable connection.

[0055] In this embodiment, the locking part 22 has an inclined surface that guides the power connector 4 to engage. This inclined surface converts the axial thrust of the power connector 4 during insertion into a lateral force that drives the locking part 22 to slide laterally, preventing a hard collision between the power connector and the locking part. Users do not need to apply significant force; a gentle push of the power connector is sufficient to guide the locking part and achieve subsequent engagement. The insertion process is smooth and unobstructed, making operation easier and more convenient, and significantly improving the user experience.

[0056] This utility model also provides a power supply device for electronic devices, including a detachable elastic clip structure for the charging cable. The power supply device for electronic devices includes a charger and a power bank. The charger includes a charging plug and a charging cable, with the charging cable mounted on the charging plug via the detachable elastic clip structure. The power bank includes a battery and a charging cable installed within a housing 1. The charging cable is mounted on the housing 1 via the detachable elastic clip structure.

[0057] The core working principle of this utility model is to achieve rapid locking and unlocking of the power connector (and the connected charging cable) through the elastic restoring force of the elastic element and the sliding linkage of the buckle element. Specifically, it is divided into a locking process and an unlocking process, and the various components work together as follows:

[0058] I. Locking Process (Fixing the Power Connector)

[0059] In the initial state, the elastic member 3 is in a naturally extended state, with its two ends abutting against the housing 1 and the sliding part 21 respectively. Under the action of elastic force, the sliding part 21 is pushed to move along a preset trajectory, so that the locking part 22 connected to one end of the sliding part 21 is kept in the "to be locked" position.

[0060] When it is necessary to fix the charging cable, align the power connector 4 of the charging cable with the mounting position (such as the limiting port 13) of the housing 1 and insert it. During the insertion process, the front end of the power connector 4 will be squeezed against the contact surface of the locking part 22 (a chamfer can be provided to reduce friction).

[0061] The compressive force overcomes the elastic force of the elastic member 3, causing the locking part 22 to synchronously pull the sliding part 21 to slide closer to the elastic member 3, and the elastic member 3 is compressed and stores elastic potential energy.

[0062] Continue inserting the power connector 4 until the slot 40 on the power connector 4 is precisely aligned with the position of the locking part 22. At this point, the squeezing force of the power connector 4 on the locking part 22 disappears.

[0063] The elastic element 3 releases the stored elastic potential energy and pushes the sliding part 21 back to reset. The sliding part 21 drives the locking part 22 to be inserted into the slot 40 of the power connector 4. Through the locking action of the locking part 22 and the slot 40, the power connector 4 is firmly fixed on the housing 1, completing the locking of the charging cable. At this time, power can be supplied normally through the power connector 4.

[0064] II. Unlocking Process (Disassembling the Power Connector)

[0065] When it is necessary to disconnect the charging cable, press the operation part 23 (the operation part 23 is fixedly connected to the sliding part 21).

[0066] The pressure is transmitted to the sliding part 21 through the operating part 23, which drives the sliding part 21 to move towards the elastic member 3. The sliding part 21 squeezes the elastic member 3 to compress it, and at the same time, the locking part 22 at the other end of the sliding part 21 moves synchronously with the sliding part.

[0067] As the locking part 22 moves, it gradually disengages from the slot 40 of the power connector 4, and the power connector 4 loses its locking constraint. At this time, there is no fixed relationship between the power connector 4 and the housing 1.

[0068] Simply pull the power connector 4 (and the connected charging cable) out of the mounting position (such as the limiting port 13) of the housing 1 to complete the disassembly of the charging cable;

[0069] After the operating part 23 is released, the elastic element 3 releases its elastic potential energy again, pushing the sliding part 21 to reset. The sliding part 21 simultaneously drives the operating part 23 and the locking part 22 back to the initial "to be locked" position, and the entire structure returns to its initial state, ready for the next locking operation.

[0070] In summary, this utility model utilizes a mechanical linkage logic of "elastic element energy storage - external force unlocking - elastic reset locking" to achieve rapid fixing and disassembly of the charging cable without complex operations. It only requires two simple actions: "inserting the power connector" and "pressing the operating part + pulling out the power connector," thus balancing connection stability and ease of operation.
