[0003] The springs for charging cradles usually refer to the elastic metal parts used for contact and conduction in charging cradles or chargers. They are designed to automatically contact and provide a stable current transmission path when a charging device (such as a mobile phone, tablet or battery) is inserted.

[0004] The shortcomings of the existing technical solutions are that due to interference from the external environment, improper use, aging and wear of components, etc., the positive and negative electrode springs may come into contact with the conductive material, which may cause the circuit to overheat and damage the electronic components. However, the charging stations currently on the market are not equipped with relevant insurance mechanisms. Utility Model Content

[0005] The purpose of the utility model is to provide a spring sheet structure for a charging stand to solve the technical problem in the prior art that the positive and negative spring sheets may come into contact with conductive materials due to interference from the external environment, improper use, aging and wear of components, etc.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0007] A spring sheet structure for a charging stand comprises a charging box, wherein an inlet is provided at the upper end of the charging box, and a limiting column is fixedly connected to the bottom of the charging box. The device also comprises a spring sheet assembly, wherein two groups of the spring sheet assemblies are arranged in a mirror-image manner inside the charging box, and each group of the spring sheet assemblies comprises a vertical sheet and an electrode sheet fixedly connected to the bottom of the charging box, a resistance sheet is fixedly connected to the vertical sheet, a pressing sheet matching the electrode sheet is fixedly connected to the bottom of the resistance sheet, and an electrode wire is externally connected to the electrode sheet.

[0008] As a further solution of the utility model: a bent plate body matching with the vertical plate is arranged at the upper end of the electrode plate.

[0009] As a further solution of the utility model: two groups of shielding mechanisms cooperating with spring elements are fixedly connected on both sides of the entrance, each group of the shielding mechanisms includes an upper baffle plate movably hinged to the edge of the entrance, a lower baffle plate is arranged below the upper baffle plate, and the upper baffle plate and the lower baffle plate cooperate with the corresponding spring elements.

[0010] As a further solution of the present invention: a pad is provided at the bottom of the charging box.

[0011] As a further solution of the utility model: an elastic telescopic rod is provided between the upper baffle and the corresponding lower baffle, and a clamping block is fixedly connected to the lower baffle.

[0012] As a further solution of the utility model: a shielding plate that cooperates with the spring assembly is fixedly connected to the inside of the charging box, and an opening that cooperates with the abutment sheet is formed on the shielding plate.

[0013] Beneficial effects of the utility model:

[0014] 1. When the utility model needs to charge the electrical appliance, the electrical appliance can be loaded into the charging box from the insertion port, and the two groups of charging electrodes of the electrical appliance are squeezed against the corresponding contact sheets. The contact sheets are deformed after being squeezed, thereby driving the pressing sheet to squeeze the electrode sheet on one side of the pressing sheet through the edge. At this time, the contact area between the pressing sheet and the electrode sheet is small, so that the current is limited. After that, the electrode sheet contacts the vertical sheet under the action of the pressing sheet, so that the current inside the electrode sheet is connected to the charging electrode of the electrical appliance through the pressing sheet, the contact sheet, the vertical sheet and other conductive components, thereby achieving the charging effect. When the squeezing force on the pressing sheet is insufficient, the current on the electrode sheet will be limited, thereby reducing the risk of short circuit of the charging device after the conductive material is accidentally touched.

[0015] 2. In the process of pushing the electrical appliance into the charging box, the lower end of the electrical appliance will contact the card block and push the card block downward, while squeezing the upper baffle and the lower baffle to both sides. The card block drives the elastic telescopic rod to extend, so that the gap between the upper baffle and the lower baffle becomes larger and larger, and the lower baffle slides to the bottom of the contact piece under the squeezing of the electrical appliance. The contact piece squeezes the charging electrode of the electrical appliance, which can not only realize charging, but also fix the electrical appliance. After the electrical appliance is fixed, the lower baffle will be limited. When the electrical appliance is taken out, the lower baffle will be reset along the bottom of the contact piece and block the contact piece again, so as to protect the contact piece.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0023] Such as Figures 1-4As shown in the figure, a shrapnel structure for a charging stand includes a charging box 1. An insertion opening 4 is provided at the upper end of the charging box 1. A limiting post 6 is fixedly connected to the bottom of the charging box 1. The device further includes a shrapnel assembly 2. There are two groups of shrapnel assemblies 2, and the two groups of shrapnel assemblies 2 are arranged in a mirror image inside the charging box 1. Each group of shrapnel assemblies 2 includes a vertical piece 201 fixedly connected to the inner bottom of the charging box 1 and an electrode piece 204. A contact piece 202 is fixedly connected to the vertical piece 201. The contact piece 202 is responsible for contacting the charging electrode of the electrical appliance. A pressing piece 203 that cooperates with the electrode piece 204 is fixedly connected to the bottom of the contact piece 202. An electrode wire is externally connected to the electrode piece 204 to provide voltage for the electrode piece 204. When not charging, the vertical piece 201, the contact piece 202, the pressing piece 203 and the electrode piece 204 are not in contact. When charging an electrical appliance, the electrical appliance can be inserted into the charging box 1 from the insertion opening 4, and the two charging electrodes of the electrical appliance squeeze the corresponding contact pieces 202. After being squeezed, the contact piece 202 deforms, thereby driving the pressing piece 203 to squeeze the electrode piece 204 on one side of the pressing piece 203 through the edge. The electrode piece 204 contacts the vertical piece 201 under the action of the pressing piece 203, so that the voltage inside the electrode piece 204 is conducted to the charging electrode of the electrical appliance through conductive components such as the pressing piece 203, the contact piece 202, and the vertical piece 201, thus achieving the charging effect. When the squeezing force borne by the pressing piece 203 is insufficient, the current on the electrode piece 204 will be restricted, thereby reducing the risk of short circuit of the charging device after the conductive material is accidentally touched.

[0024] In some specific embodiments, in order to ensure the charging efficiency, a bent plate body that cooperates with the vertical piece 201 is provided at the upper end of the electrode piece 204. During the installation of the electrical appliance, the pressing piece 203 will contact the electrode piece 204. Since the contact area between the two is small, the overall conductivity of the shrapnel assembly 2 is poor. When the contact piece 202 continues to press the pressing piece 203, the electrode piece 204 deforms and falls towards the vertical piece 201. At this time, the bent plate body at the upper end of the electrode piece 204 contacts the vertical piece 201, and the vertical piece 201 is parallel to the bent plate body, and there is a large contact surface between the two, so that the voltage on the electrode piece 204 is completely guided into the vertical piece 201, thus ensuring the charging effect.

[0025] In some specific embodiments, in order to prevent external conductive materials from accidentally touching the shrapnel assembly 2 and causing a short circuit, two groups of shielding mechanisms 5 that cooperate with the shrapnel assembly 2 are fixedly connected to both sides of the insertion opening 4. Each group of shielding mechanisms 5 includes an upper baffle 501 that is movably hinged to the edge of the insertion opening 4. A lower baffle 503 is provided below the upper baffle 501. The upper baffle 501 and the lower baffle 503 cooperate with the corresponding shrapnel assembly 2. When the upper baffle 501 and the lower baffle 503 naturally fall, they will cover the shrapnel assembly 2, thereby reducing the possibility of external conductive materials accidentally touching the shrapnel assembly 2 and causing a short circuit.

[0026] In some specific embodiments, in order to ensure that the height of the charging electrode of the electrical appliance is the same as the height of the contact piece 202, a cushion block 3 is provided at the bottom of the charging box 1; the cushion block 3 can ensure that the charging electrode of the loaded electrical appliance can cooperate with the contact piece 202 to complete the charging process.

[0027] In some specific embodiments, in order to prevent the lower baffle 503 from blocking the normal docking of the charging electrode and the corresponding contact piece 202, an elastic telescopic rod 502 is cooperatively arranged between the upper baffle 501 and the corresponding lower baffle 503. The elastic telescopic rod 502 is hidden inside the upper baffle 501, and the extending end is fixedly connected to the lower baffle 503 to ensure that there is no passable gap between the upper baffle 501 and the lower baffle 503. A clamping block 504 is fixedly connected to the lower baffle 503. In order to reduce the possibility of accidental touch, the volume of the clamping block 504 is very small; during the process of pushing the electrical appliance into the charging box 1, the lower end of the electrical appliance will contact the clamping block 504 and push the clamping block 504 downward, and at the same time squeeze the upper baffle 501 and the lower baffle 503 to both sides. The clamping block 504 drives the elastic telescopic rod 502 to extend, so that the gap between the upper baffle 501 and the lower baffle 503 becomes larger and larger. The lower baffle 503 slides down to the bottom of the contact piece 202 under the extrusion of the electrical appliance, and the contact piece 202 extrudes the charging electrode of the electrical appliance, which can not only realize charging but also fix the electrical appliance. After the electrical appliance is fixed, it will limit the lower baffle 503. When the electrical appliance is taken out, the lower baffle 503 will reset along the bottom of the contact piece 202 and block above the contact piece 202 again to protect the contact piece 202.

[0028] In some specific embodiments, in order to reduce the influence of the outside world on the elastic piece assembly 2, a shielding baffle 7 cooperatively connected with the elastic piece assembly 2 is fixedly connected inside the charging box 1. An opening cooperatively connected with the contact piece 202 is provided on the shielding baffle 7, and the shielding baffle 7 extends out from the opening; the shielding baffle 7 can reduce the possibility of the outside object contacting the electrode piece 204 and reduce the influence of the outside world on the conductivity of the elastic piece assembly 2. The shielding baffle 7 plays a guiding role in both the loading and unloading of the electrical appliance.

[0029] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of the embodiments of this solution will be described below in combination with a specific application scenario:

[0030] When charging an electrical appliance is required, the electrical appliance can be inserted into the interior of the charging box 1 from the insertion port 4, and the two sets of charging electrodes of the electrical appliance press against the corresponding contact pieces 202. After being pressed, the contact pieces 202 deform, thereby driving the pressing piece 203 to press the electrode piece 204 located on one side of the pressing piece 203 through the edge. Since the contact area between the two is small, the overall conductivity of the elastic piece assembly 2 is poor. When the contact piece 202 continues to press the pressing piece 203, the electrode piece 204 deforms and falls towards the vertical piece 201. At this time, the bent plate body at the upper end of the electrode piece 204 contacts the vertical piece 201, and the vertical piece 201 is parallel to the bent plate body, and there is a large contact surface between the two, so that the voltage on the electrode piece 204 is completely guided into the vertical piece 201, thus ensuring the charging effect. When the extrusion force borne by the pressing piece 203 is insufficient, the current on the electrode piece 204 will be restricted, thereby reducing the risk of short circuit of the charging device after the conductive material is accidentally touched;

[0031] When the upper baffle 501 and the lower baffle 503 fall naturally, they will cover the elastic piece assembly 2, thereby reducing the possibility of short circuit caused by external conductive materials accidentally touching the elastic piece assembly 2. During the process of pushing the electrical appliance into the charging box 1, the lower end of the electrical appliance will contact the latch 504 and push the latch 504 downward, while squeezing the upper baffle 501 and the lower baffle 503 to both sides. The latch 504 drives the elastic telescopic rod 502 to extend, making the gap between the upper baffle 501 and the lower baffle 503 larger and larger. The lower baffle 503 slides down to the bottom of the contact piece 202 under the extrusion of the electrical appliance. The contact piece 202 presses the charging electrode of the electrical appliance, realizing charging while also fixing the electrical appliance. After the electrical appliance is fixed, it will limit the lower baffle 503. When the electrical appliance is taken out, the lower baffle 503 will reset along the bottom of the contact piece 202 and block above the contact piece 202 again, playing a protective role for the contact piece 202.

All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
