Description
Technical Field
[0001] This utility model relates to the field of charging structures, specifically to a charging structure for an anti-loss device. Background Technology
[0002] An anti-loss device, as the name suggests, is used to prevent items from being lost.

Anti-loss devices can be used to prevent the loss of valuables such as mobile phones, wallets, keys, and luggage, and can also be used to prevent children from getting lost, pets from getting lost, and for vehicle location tracking.
[0003] Existing anti-loss devices generally use small batteries, and some are rechargeable via USB. When charging is needed, they can be plugged into the power cord. However, since some anti-loss devices are installed on small items, adding a USB interface would greatly increase the thickness and area of the device, making it unsuitable for installing small items such as keys.
[0004] Therefore, designing an anti-loss device with charging contacts can greatly reduce the area of the anti-loss device. However, ensuring good contact between the charger and the contacts during charging is a key issue that needs to be considered. Utility Model Content

[0024] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.
[0025] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figures 1-7 As shown, the charging structure of the anti-loss device of this utility model includes a first clamp 2 and a second clamp 1 that can be self-resetting hinged by an elastic member 3. The first clamp 2 is provided with a cavity, and a charging plate 204 is provided in the cavity. The charging plate 204 is provided with a charging circuit, positive and negative charging probes 202 respectively connected to the charging circuit, and a charging interface 201.
[0028] This invention was developed to work in conjunction with miniature anti-loss devices. It utilizes a probe-contact charging method, making it suitable for contact-charging anti-loss devices. Because these devices are small, they require limiting their position during charging. This invention addresses this by designing the charger housing as a first clamp and a second clamp. When the anti-loss device's contacts contact the positive and negative charging probes 202, the clamp holds and limits the device, ensuring good electrical contact. When charging is needed, the charging interface 201 at the rear is connected to an external power source. The anti-loss device is clamped between the first clamp 2 and the second clamp 1, ensuring good contact between the contacts and the positive and negative charging probes 202. This effectively prevents the anti-loss device from shifting or being lost during charging, making operation simple and convenient.
[0029] like Figure 1 and Figure 2As shown, in the first embodiment of this utility model, the first clamp 2 is the upper clamp and the second clamp 1 is the lower clamp. The lower clamp is provided with a limiting structure to limit the clamping position of the anti-loss device.
[0030] Preferably, the limiting structure in this example includes an X-direction baffle 104 that limits the insertion direction of the anti-loss device in the X direction and a Y-direction baffle 105 that limits the left and right positions of the anti-loss device. Of course, this example can also be set as an L-shaped baffle, or a limiting curve or multiple trajectory points that match the shape of the anti-loss device, etc.
[0031] The upper and lower clamps are hinged together by hinge structures 2057 and 101. In this example, the outer wall of the hinge structure 2057 encloses a receiving groove for accommodating the elastic element 3. The elastic element 3 between the first clamp 2 and the second clamp 1 is used to control the clamping or releasing of the anti-loss device. The first clamp 2 includes a base 205 and a cover plate 203 that covers the base 205 to form a cavity. The base 205 has a groove, and a plurality of reinforcing posts 2051 are provided in the groove. A support post 2054 is also provided in the groove. The charging plate 204 is disposed on the support post 2054. In addition, a screw hole is provided in the middle of the reinforcing post 2051. The charging plate 204 is also provided with a fixing hole at the corresponding position of the support post 2054. The charging plate 204 is locked to the reinforcing post 2051 by screws.
[0032] In this example, a stepped surface 2055 is provided on the side wall of the groove for limiting the installation of the cover plate 203. Several latches 2056 are provided above the stepped surface 2055 on the side wall of the groove, and corresponding latches 2036 are provided on the side wall of the cover plate 203. The cover plate 203 is fixed to the stepped surface 2055 of the base 205 by the latches 2036. Alternatively, this example can also be used without latches, by providing a second screw hole at the corresponding position of the support column 2054, and locking the cover plate 203 and charging plate 204 together onto the reinforcing column 2051 with screws.
[0033] In this example, the cover plate 203 is provided with probe holes 2031 corresponding to the positive and negative charging probes 202. The positive and negative charging probes 202 extend out from the probe holes 2031. The base 205 is provided with interface holes 2053 corresponding to the charging interface 201, which are used to connect the charging interface 201 to an external power source.
[0034] In this example, corresponding positioning structures 206 and 106 are also provided at the ends of the first clamp 2 and the second clamp 1 away from the probe hole 2031, to facilitate user operation and open or close the new anti-loss charging structure. Alternatively, silicone or rubber can be injected into the outer surface of the positioning structures 206 and 106, or an anti-slip structure can be provided to improve user convenience.
[0035] Preferably, the charging plate 204 in this example is provided with an indicator light 2044 to indicate the charging status, and the first clamp 2 is provided with an indicator window 2034 corresponding to the indicator light 2044. In this example, the indicator light 2044 is located near the charging interface 201 on the cover plate 203. When the charging structure in this example comes into contact with the anti-loss device, the indicator light 2044 lights up, thereby indicating the charging status to the user. Of course, in this example, a waterproof layer can also be provided on the indicator window 2034, and a waterproof ring or other waterproof structure can be added between the base and the cover plate to achieve overall waterproofing.
[0036] like Figures 3-6 As shown in the second embodiment of this utility model, the first clamp 2 is the lower clamp and the second clamp 1 is the upper clamp. The lower clamp is provided with a mounting groove 2052. The charging plate 204 is provided with a mounting hole 2042 that matches the position and shape of the mounting groove 2052. The cover plate 203 is provided with an abutment plate 2032 that cooperates with the mounting cavity. The abutment plate 2032 and the mounting groove 2052 form a first mounting cavity. One end of the elastic member 3 is disposed in the mounting cavity, and the other end of the elastic member 3 is disposed in the second mounting cavity 102 on the second clamp 1.
[0037] like Figure 5 and Figure 6 As shown, in this example, the front end of the clamp is provided with a probe hole 2031 corresponding to the charging probe and an interface hole 2053 corresponding to the charging interface 201. The positive and negative charging probes 202 extend out from the probe hole 2031. The second clamp 1 is provided with a clearance structure at the position corresponding to the positive and negative charging probes 202.
[0038] Specifically, the first clamp 2 and the second clamp 1 are hinged together by hinge structures 101 and 2033. The elastic element 3 between the first clamp 2 and the second clamp 1 is used to control the clamping or releasing of the anti-loss device. The first clamp 2 includes a base 205 and a cover plate 203 that covers the base 205 to form a cavity. The base 205 has a mounting groove 2052 in the middle. The charging plate 204 has a mounting hole 2042 that matches the position and shape of the mounting groove 2052. The cover plate 203 has an abutment plate 2032 that cooperates with the mounting cavity. The abutment plate 2032 and the mounting groove 2052 form a first mounting cavity. One end of the elastic element 3 is disposed in the mounting cavity, and the other end of the elastic element 3 is disposed in the second mounting cavity 102 on the second clamp 1.
[0039] Preferably, in this example, the cover plate 203 is provided with a plurality of positioning pins 2035. The charging plate 204 is provided with positioning holes 2043 corresponding to the positioning pins 2035, through which the positioning pins pass. The base 205 is provided with reinforcing pins 2051 corresponding to the positioning pins 2035. The center of the reinforcing pin 2051 is provided with a fixing hole that mates with the positioning pins. The cover plate 203 and the base 205 are fixed above the reinforcing pins 2051 by the positioning pins 2035, and the charging plate 204 is pressed onto the reinforcing pins 2035 for fixation. As another embodiment of this utility model, the positioning pins 2035 are replaced with threaded holes, and then the cover plate 203 and the base 205 are fixed by screws. In this example, a sealing ring is provided on the mating surface between the base 205 and the cover plate 203 to improve the waterproof effect inside the base 205.
[0040] like Figure 5 and Figure 6 As shown, in order to protect the positive and negative charging probes 202, an avoidance structure is also provided on the upper clamp to avoid the positive and negative charging probes 202. The avoidance structure is an insulating layer 103 provided at the front end of the second clamp 1 near the first clamp. The insulating layer 103 includes a sidewall that matches the outer edge of the second clamp 1 and a plurality of grids 1031 connected to the sidewall. An avoidance channel 1032 is provided between two adjacent grids 1031. The positive charging probe and the negative charging probe are arranged in different avoidance channels 1032.
[0041] Preferably, several grids 1031 are arranged parallel to each other along the insertion direction of the anti-loss device, and the grids 1031 between the positive charging probe and the negative charging probe can support the anti-loss device to be charged, resulting in a better fixing effect.
[0042] As another embodiment of this utility model, the avoidance structure can also be improved by designing the grille 1031 of the above embodiment. Each grille encloses a circular, U-shaped, or arc-shaped avoidance groove, and the positive charging probe and the negative charging probe are arranged in different avoidance grooves. The grille surrounding the avoidance groove can effectively support the anti-loss device and can effectively prevent the clamping deformation of the flexible anti-loss device, resulting in poor contact. In this example, two solder points 2041 are provided on the charging board for welding electrical connection with the positive and negative charging probes 202.
[0043] like Figure 7As shown, the charging interface can be any type of USB interface; in this example, it is a reversible TYPE-C interface. The charging circuit includes a charging chip U1, a positive solder joint TP2 and a negative solder joint TP3 connected to the positive and negative charging probes, and a TYPE-C interface. The power input pin 1 of the charging chip U3 is connected to the power pins A9 / B9 of the TYPE-C interface, and the power output pin 5 of the charging chip U1 is connected to the positive solder joint TP4. The negative solder joint TP3 is grounded. To make the circuit more stable, two grounded filter capacitors C3 and C4 are placed on the power output pin 5, and two grounded filter capacitors C1 and C2 are also placed between the power input pin 1 of the charging chip U1 and the power pins A9 / B9 of the TYPE-C interface.
[0044] The charging circuit in this example also includes a charging indicator module connected to the charging chip U1. The charging indicator module includes a first resistor, a second resistor, an indicator LED1, and an indicator LED2. Pin 7 of the charging chip U1 is connected to the negative terminal of indicator LED1 through the first resistor. The positive terminal of indicator LED1 is connected to the power pin of the USB interface. Pin 6 of the charging chip U1 is connected to the negative terminal of indicator LED2 through the second resistor. The positive terminal of indicator LED2 is connected to the power pin of the USB interface.
[0045] When the TYPE-C interface is connected to an external power source, the positive terminals of indicator lights LED1 and LED2 are energized. The charging chip U1 can control the working state of the two indicator lights by outputting different level signals to pins 6 and 7, thereby indicating different charging states.
[0046] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
