[0033] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Figure 1 The structure of the charging device 1 according to some embodiments of the present utility model is shown below. Figure 1 The charging device 1 will be described.

[0035] In this embodiment, the charging device 1 is used to connect with and charge electronic products. The electronic products may be, for example, various types of personal terminals, or devices that implement different functions, such as cameras, speakers, display screens, etc. In this embodiment, the charging device 1 may be placed on a plane, or fixed on a vertical surface, such as by pasting, clamping, or magnetic attraction, and the electronic product may be electrically connected to the charging device 1 placed in a fixed position and charged.

[0036] The charging device 1 includes a base 10, a terminal 20, a connection structure 30 and an elastic structure 40. The base 10 can be connected to a bearing surface, for example, the bottom surface of the base 10 is processed into a plane and can be placed on a horizontal surface. Furthermore, a non-slip pad or adhesive can be provided on the bottom surface of the base 10 to keep the charging device 1 fixed.

[0037] The connection terminal 20 is arranged on the base 10, and is arranged so that the connection terminal 20 can be electrically connected to the electronic product, and the connection terminal 20 matches the charging interface of the electronic product. The connection terminal 20 can be arranged to include multiple electrical connection components, for example, respectively for power supply and grounding. The electrical connection components in the connection terminal 20 can also be symmetrically arranged, and the symmetrically arranged electrical connection components have the same definition, so that the electronic product can match the connection terminal 20 in different directions. In a specific embodiment of the utility model, the node terminal 20 includes, for example, a pogo pin probe.

[0038] The connection structure 30 is movably connected to the base 10 and can be switched between a first position and a second position. When the connection structure 30 is in the first position, the terminal 20 is covered by the connection structure 30. When the connection structure 30 moves relative to the base 10 and switches to the second position, the terminal 20 can extend to the outside of the connection 30. In some embodiments of the utility model, the connection structure 30 may not be provided with a cover plate, and a through hole is provided on the connection structure 30. The position of the through hole corresponds to the position of the terminal 20, so that when the connection structure 30 moves relative to the base 10, the terminal 20 can pass through the through hole. Preferably, the connection structure 30 can be provided with an openable and closable cover plate at the position of the through hole. When the connection structure 30 is in the first position, the terminal 20 is completely covered by the cover plate, which can prevent dust particles and other objects in the external environment from entering the interior of the charging device 1.

[0039] In some embodiments of the utility model, the shape of the connection structure 30 is set to match the shape of the charging interface of the electronic product, so that the electronic product can be connected to the connection structure 30, and the connection structure 30 can improve the stability of the connection between the electronic product and the charging device 1. Furthermore, the shape of the connection structure 30 can also be set to have an interference fit with the shape of the charging interface of the electronic product, or a certain damping can be set to further improve the stability of the electronic product charging on the charging device 1.

[0040] The elastic structure 40 is disposed between the base 10 and the connection structure 30, and the elastic structure 40 is configured to bias the connection structure 30 toward the first position, that is, in this embodiment, under the action of the elastic structure 40, the connection structure 30 is maintained in the first position, and when the electronic product is not connected to the charging device 1, the connection structure 30 can cover the connection terminal 20 to protect the connection terminal 20. When the electronic product needs to be charged, under the action of an external force, the elastic structure 40 undergoes elastic deformation, the connection structure 30 can move to the second position relative to the base 10, and the connection terminal 20 extends to the outside of the connection structure 30, and can be electrically connected to the charging interface of the electronic product, without affecting the normal use of the charging device 1.

[0041] In different embodiments of the present invention, the elastic structure 40 may specifically be a coil spring, a spring sheet, an elastic diaphragm, etc., and is not limited to a fixed form.

[0042] According to a preferred embodiment of the utility model, the elastic structure 40 is pre-loaded with deformation so that the connection structure 30 can be maintained in the first position, which can prevent the elastic structure 40 from loosening due to aging, thereby extending the service life of the charging device 1. When the connection structure 30 is under pressure, the elastic structure 40 undergoes elastic deformation, and the connection structure 30 moves from the first position to the second position. In this embodiment, the connection structure 30 moves under pressure. When the electronic product needs to be charged, it moves in a direction close to the charging device 1, and at the same time, pressure is applied to the connection structure 30, and the elastic structure 40 undergoes elastic deformation. The connection structure 30 can move to the second position, and the wiring port 20 can be electrically connected to the charging interface of the electronic product. At the same time, the elastic structure 40 accumulates elastic potential energy. When the electronic product and the charging device 1 are separated, the pressure applied to the connection structure 30 is removed, and the elastic structure 40 releases the elastic potential energy, driving the connection structure 30 to move to the first position, covering the wiring terminal 20.

[0043] Further, such as Figure 2 and Figure 3 As shown, the connection structure 30 protrudes from the surface of the base 10, and the movement direction of the connection structure 30 relative to the base 10 is parallel to the connection direction between the electronic product and the terminal 20. For example, the charging device 1 is placed in a horizontal plane, the terminal 20 is arranged in a vertical direction, and the electronic product and the terminal 20 are plugged and connected in an approximately vertical direction. In this embodiment, the connection structure 30 moves in the vertical direction relative to the base 10. The movement directions of the connection structure 30 and the electronic product are roughly parallel, which can reduce the lateral extrusion between the connection structure 30 and the base 10, which is beneficial to the structural stability of the charging device 1.

[0044] like Figure 2 As shown, in a preferred embodiment of the present invention, the elastic structure 40 includes a coil spring, wherein the coil spring is arranged along the movement direction of the connecting structure 30 relative to the base 10, for example, the connecting structure 30 moves in a vertical direction relative to the base 10, and the coil spring is arranged vertically. One end of the coil spring abuts against the base 10, and the other end of the coil spring abuts against the connecting structure 30. When the connecting structure 30 moves relative to the base 10, the coil spring is compressed to different lengths along the axial direction.

[0045] like Figure 2 As shown, according to a preferred embodiment of the present utility model, the charging device 1 further comprises a guide structure 50, which is disposed between the base 10 and the connecting structure 30, and the guide structure 50 is fixedly connected to the base 10 and / or the connecting structure 30, and is used to limit the movement direction of the connecting structure 30 relative to the base 10. Further, the coil spring may be disposed around the circumference of the guide structure 50.

[0046] Specifically, the guide structure 50 can be set to a cylindrical or prismatic shape. The guide structure 50 is fixedly connected to the connection structure 30. Accordingly, a countersunk hole or a through hole is opened on the base 10, and the position corresponds to the position of the guide structure 50. When the connection structure 30 moves relative to the base 10, the guide structure 50 moves in the through hole or the countersunk hole to limit the movement direction of the connection structure 30. In some embodiments of the utility model, the guide structure 50 can also be set on the base 10, and a countersunk hole or a through hole is set on the connection structure 30, preferably a countersunk hole, to ensure the consistency of the appearance of the charging device 1. In other embodiments of the utility model, the guide structure 50 can also be set on the base 10 and on the connection structure 30.

[0047] like Figure 2 As shown, in a preferred embodiment of the utility model, a step structure 11 is provided on the base 10 and / or the connecting structure 30, and the step structure 11 is configured to be convex or concave relative to the connecting surface, wherein the connecting surface refers to the surface connected to the step structure 11, which may be the surface of a partial structure in the base 10, or may be a partial surface in the connecting structure 30.

[0048] In this embodiment, the coil spring and the step structure 11 are interference fit, and the coil spring is sleeved on the outside of the protruding step structure 11, or embedded in the inside of the recessed step structure 11. The step structure 11 can further limit the elastic force direction of the coil spring and prevent the coil spring from falling off or being subjected to lateral pressure to cause irreversible plastic deformation, which affects the service life of the charging device 1.

[0049] According to different embodiments of the utility model, the elastic structure 40 may further include a leaf spring, which may be configured to be preloaded and deformed so as to keep the connection structure 30 in the first position. The structure of the leaf spring is similar to a wedge, and the top angle of the wedge becomes smaller after being compressed, and the leaf spring returns to its initial shape after the pressure is removed. A groove is provided on the base 10 and / or the connection structure 30, and the leaf spring abuts on the groove. The groove can be used to fix the leaf spring, and one end or both ends of the leaf spring abuts against the inside of the groove to prevent the leaf spring from falling off.

[0050] In other embodiments of the present invention, the base 10 is connected to the connection structure 30 via the elastic structure 40, and the elastic structure 40 is disposed around the circumference of the connection structure 30. Figure 3 In the connection structure 30 shown in FIG, the side slope close to the base 10 is made of elastic material, such as rubber, silicone, etc. When the connection structure 30 is compressed, the elastic material is deformed, and the connection terminal 20 extends to the outside of the connection structure 30. When the connection structure 30 is not compressed or the pressure is removed, under the action of the elastic material, the elastic structure 40 returns to its original shape, and the connection structure 30 covers the connection terminal 20.

[0051] In this embodiment, the elastic structure 40 is preferably configured to surround and completely cover the connection position between the base 10 and the connection structure 30, so that the connection structure 30 can remain sealed when moving relative to the base 10, further reducing the impact of dust and debris on the charging device 1.

[0052] In a preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the connection structure 30 includes a limiting portion 31, which is limited inside the base 10 to prevent the connection structure 30 from being separated from the base 10. The limiting portion 31 can be a skirt extending outward, and a through hole is provided on the base 10. The end of the connection structure 30 opposite to the limiting portion 31 extends from the position of the through hole to the outside of the base 10, and the end of the connection structure 30 where the limiting portion 31 is provided is limited by the edge structure of the through hole to prevent the connection structure 30 from being completely separated from the base 10. In different embodiments of the utility model, the limiting portion 31 can also be set as a buckle structure or other structures.

[0053] According to a preferred embodiment of the present utility model, Figure 1 As shown, the base 10 includes a magnetic member 12, and the charging device 1 is magnetically connected to the electronic product through the magnetic member 12, for example, a magnet with opposite polarity to the magnetic member 12 is arranged inside the electronic product. When charging is not required, the magnetic member 12 may absorb foreign particles in the environment, affecting the safety of the electrical components inside the charging device 1. In this embodiment, the elastic structure 40 keeps the connection structure 30 in the first position, which can reduce the gap and reduce the environmental impact.

[0054] Finally, it should be noted that the above description is only an embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
