DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Existing small and micro smart products, such as smart watches and smart bracelets, generally use magnetic charging. However, this charging method has some inherent drawbacks, such as insufficient magnetic force, misalignment caused by external interference (such as dust and sweat), and unstable connection.

[0027] In order to solve the above problems, the present application proposes a charging clip, which is preferably suitable for a glasses anti-lost device, to achieve fast and reliable charging connection and stable charging of the glasses anti-lost device.

[0028] Reference Figures 1 to 5The charging clamp of the embodiment of the present utility model includes a bottom clamping piece 1 and a top clamping piece 2. The clamping end of the bottom clamping piece 1 is provided with a stop plate 11 for pressing against the external charged terminal and a bottom concave surface 12 that matches the shape of the external charged terminal. The bottom concave surface 12 is convexly provided with a charging spring 13 for contacting and charging the external charged terminal. The top clamping piece 2 is rotatably connected to the bottom clamping piece 1 via a self-resetting hinge structure. The clamping end of the top clamping piece 2 is provided with a top concave surface 21 that matches the shape of the external charged terminal. The top concave surface 21 and the bottom concave surface 12 form a charging cavity that matches and clamps the external charged terminal. Through this structural design, the stop plate 11 presses against the external charged terminal and the charging cavity matches and accommodates the external charged terminal, thereby achieving rapid alignment of the charging clamp to the external charged terminal, stable clamping, and reliable charging, effectively preventing users from connecting the terminal in the wrong direction, and achieving the purpose of blind clamping. Among them, the top clip 2 and the bottom clip 1 are connected by a self-resetting hinge structure, which can automatically reset and keep the charging clip automatically closed when not in use, further improving the convenience and reliability of the charging clip.

[0029] Furthermore, the present application also proposes that the charging clamp has two charging spring pins 13, which are arranged in a staggered height. This design aims to solve the problems of poor charging contact and anti-lost device sliding out in the existing charging structure, thereby improving charging efficiency and stability and ensuring the smooth progress of the charging process. The purpose of designing a higher charging spring pin 13 is to clamp the external charged terminal a little tighter. In addition to charging, the tighter charging spring pin 13 also has another function of preventing the external charged terminal from sliding out. The looser charging spring pin 13 only serves as a charging contact. If both are designed to be very tight, the anti-lost device will be damaged.

[0030] In one embodiment, the self-resetting hinge structure comprises a first connecting lug 14 extending upward from both sides of the center of the bottom clip 1, and a second connecting lug 22 extending downward from both sides of the center of the top clip 2. The first connecting lug 14 is provided with a pin 15, while the second connecting lug 22 is provided with a first connecting hole 23 that mates with the pin 15. The beveled snap-in design at the end of the pin 15 facilitates quick assembly, simplifies the assembly process, and improves assembly efficiency and connection stability.

[0031] Correspondingly, a first pin 16 protrudes from the inner surface of the pressing end of the bottom clip 1, securing one end of the elastic member 3. A second pin 24 protrudes from the inner surface of the pressing end of the top clip 2, securing the other end of the elastic member 3. Both the first pin 16 and the second pin 24 protrude from the bottom of the groove, with diameters matching those of the elastic member 3. The elastic member 3 is preferably a spring, providing the reset force for the self-resetting hinge structure, ensuring that the charging clamp automatically closes when not in use.

[0032] In another embodiment, the self-resetting hinge structure comprises a bottom clip 1 having two upwardly extending central portions on either side thereof, each of which has a second connecting hole formed therein for engagement with the rotating shaft. A top clip 2 has two downwardly extending central portions on either side thereof, each of which has a third connecting hole formed therein for engagement with the rotating shaft. The rotating shaft passes through the second and third connecting holes, and two legs of a retaining spring extending through the rotating shaft elastically abut against the bottom clip 1 and the top clip 2, respectively. The elastic abutment of the retaining spring effectively maintains the two clips in a closed state, preventing them from loosening or falling off due to external forces during use, thereby resolving the unstable connection issue in the prior art.

[0033] Furthermore, the bottom clip 1 includes a housing cavity, which houses a charging circuit board 4, which is equipped with a charging indicator light. In this application, the charging circuit structure is placed within the charging clip, improving the lightweight and compactness of the external charging terminal. The bottom clip 1 also includes a light-transmitting hole or an indicator light mounting hole to facilitate user observation of the charging indicator light status. The charging clip described in this application offers advantages such as a simple structure, easy installation, stable charging, and intuitive use.

[0034] Furthermore, the bottom clip 1 is also equipped with a USB charging plug cable that is electrically connected to the charging circuit board 4, allowing users to power the charging clip via the USB port. The USB charging plug cable provides a more stable and reliable electrical connection method, and the newly added USB charging plug cable can be implemented in a variety of ways. For example, the USB charging plug cable can be a single cable directly connected to the charging clip's circuit board; or the USB charging plug cable can have a standard USB port on one end and a MiniUSB male plug on the other end, which mates with the MiniUSB female socket on the bottom clip 1, enhancing the charging clip's applicability and lightweight.

[0035] Furthermore, reinforcing ribs are provided on the top and / or bottom clips 2 and 1 to enhance structural strength and stability. Specifically, multiple longitudinal or transverse ribs can be provided on the inner surface of the top and / or bottom clips 2 and 1, and these ribs can be evenly distributed across the clips to enhance their load-bearing capacity. Alternatively, the outer surface of the bottom clip 1 can be designed with a specific geometric shape, such as a wave or trapezoid, to increase its strength and resistance to bending.

[0036] The inner surface of the clamping end of the bottom clip 1 is provided with a first boss 17, and the inner surface of the clamping end of the top clip 2 is provided with a second boss 25. The sum of their heights is less than the corresponding height of the external charging terminal. This ensures that the charging clamp maintains a balanced state at both ends when not charging, while clamping the anti-loss device during charging to prevent it from falling off. This way, when clamping the external charging terminal, the bosses do not place additional pressure on the terminal, while ensuring the balance of the charging clamp when not in use.

[0037] Through the above design, the charging clamp of this application can effectively solve the problems of unstable charging connection and misalignment in the existing technology, providing a charging method with fast assembly, high connection reliability, convenient use and foolproofness. The clamping structure of the bottom clamp 1 and the top clamp 2 ensures that the external charged terminal can be stably fixed in the charging position, and the self-resetting hinge structure ensures the automatic closing and resetting function of the charging clamp, thereby greatly improving the user experience and charging effect of the charging clamp.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
