[0036] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0037] The connector 11 on the circuit board 1 of the electronic device needs to be pressed tightly to ensure its connection reliability. There are two ways of pressing. One is to use foam for soft pressing, and the other is to directly use the bracket 2 for hard pressing without using foam.

[0038] In mass production, due to the tolerance accumulation in the thickness direction during the manufacturing process and the deformation of the bracket 2, there will be a certain proportion of products with gaps between the pressing surface of the bracket 2 and the connector 11. If a hard pressing design is adopted, the positions where gaps are generated will cause the circuit board 1 to not press the connector 11 at all, resulting in the following failure phenomena:

[0039] 1. The position of the battery connector 11 is not pressed, and the battery connector 11 becomes loose during the use of the battery, resulting in the power supply interruption between the battery and the circuit board 1. The electronic device directly shuts down and cannot be turned on, causing the electronic device to be unable to continue to be used at all;

[0040] 2. The position of the battery connector 11 is not pressed, and due to the slight vibration during use, the battery connector 11 is frequently connected and disconnected. The power supply of the electronic device frequently switches between connected and disconnected, and the electronic components on the circuit board 1 of the electronic device are constantly subjected to frequent impacts of unstable current, resulting in the damage of the circuit board 1 of the electronic device;

[0041] 3. The positions of the connectors 11 of each camera are not pressed, and the power supply is unstable, resulting in various functional defects of the camera; in severe cases, the camera directly fails and cannot enter the shooting mode;

[0042] 4. The main and secondary board connectors 11 are not pressed, which will cause the connection between the circuit board 1 and the secondary board to be disconnected, the lower antenna cannot be used, or the electronic device motor has no power supply, and the electronic device cannot communicate normally and has no vibration problem.

[0043] Based on the above problems, at present, in the electronic device, at the position of the connector 11, foam must be used to absorb tolerance accumulation and deformation. However, this is not conducive to controlling the cost and the overall weight of the electronic device. On the one hand, adding foam will increase the material cost. On the other hand, since the foam is a secondary assembly, it will also increase the labor cost, and inspections are also required, which will also increase the labor cost.

[0044] In view of the above problems, the present application provides an electronic device, which can effectively ensure the reliability of the pressing and fixing between the bracket 2 and the connector 11 and ensure the normal use of the electronic device.

[0045] As Figure 1 and Figure 2 shown, the present application provides an electronic device, wherein the electronic device includes a circuit board 1 and a bracket 2.

[0046] A plurality of connectors 11 are provided on the circuit board 1, such as a battery connector 11, a camera connector 11, a main and sub-board connector 11, etc., to realize the electrical connection of different electronic components and enable the normal operation of each electronic component, and the electronic device has a variety of usage functions.

[0047] The bracket 2 is arranged on the side of the connector 11 away from the circuit board 1, that is, the bracket 2 and the circuit board 1 are arranged in a stacked and spaced manner, and the connector 11 is located between the circuit board 1 and the bracket 2.

[0048] The bracket 2 includes a pressing portion 21 and a main body portion 22. The surface of the pressing portion 21 facing the circuit board 1 protrudes from the surface of the main body portion 22 facing the circuit board 1. At least one pressing portion 21 is provided, and each pressing portion 21 is arranged opposite to and abuts against a connector 11. By setting the surface of the pressing portion 21 facing the circuit board 1 to protrude from the surface of the main body portion 22 facing the circuit board 1, the gap between the circuit board 1 and the bracket 2 at the position of the connector 11 due to tolerance accumulation can be compensated. During assembly, the pressing portion 21 can be made to abut against the corresponding connector 11 to perform pressing and positioning on the connector 11; at the same time, the pressing portion 21 can elastically deform in the direction close to the circuit board 1 or away from the circuit board 1. After the pressing portion 21 abuts against the connector 11, the pressing portion 21 can be made to elastically deform slightly in the direction away from the circuit board 1 to ensure that the pressing portion 21 elastically presses against the corresponding connector 11, ensure the reliable pressing and positioning of the bracket 2 on the connector 11, and ensure the normal use of the electronic device.

[0049] Optionally, the pressing portion 21 is embedded in the main body portion 22 to ensure the reliable connection between the pressing portion 21 and the main body portion 22.

[0050] As Figures 1 to 9As shown, the electronic device provided by the present application, wherein the main body 22 is substantially parallel to the circuit board 1, and the main body 22 and the circuit board 1 are stacked and spaced apart in the thickness direction thereof. A plurality of openings 221 are formed in the main body 22, and each opening 221 is disposed opposite to a connector 11. By providing the openings 221, it is equivalent to forming a hollow at the position of the main body 22 opposite to the connector 11 for providing a pressing portion 21 to abut against the connector 11.

[0051] The pressing portion 21 includes a pressing member 211 and a connecting arm 212. The pressing member 211 is located on the side of the main body 22 facing the circuit board 1, and the pressing member 211 is disposed opposite to the corresponding opening 221. Each pressing member 211 is connected to the edge of the corresponding opening 221 through at least one connecting arm 212.

[0052] Specifically, the pressing member 211 is substantially in a flat plate structure. The surface of the pressing member 211 facing the circuit board 1 abuts against the corresponding connector 11, and the connecting arm 212 can elastically deform in the direction close to or away from the circuit board 1, so as to realize the elastic deformation of the whole pressing portion 21 in the direction close to or away from the circuit board 1, thereby ensuring its elastic abutment with the connector 11. The elastic restoring force generated by the elastic deformation can effectively ensure that the pressing portion 21 reliably presses and fixes the connector 11, and at the same time avoid the situation of rigid abutment damaging the connector 11.

[0053] As Figure 2 shown, in the electronic device provided by the present application, along the through direction of the opening 221, the projection of the pressing member 211 and the projection of the connector 11 both fall into the projection of the corresponding opening 221, that is, the projection area of the opening 221 is larger than the projection area of the pressing member 211 and the projection area of the connector 11, so that the whole pressing portion 21 can be in a tapered shape with a gradually decreasing size in the direction close to the circuit board 1. When an external force is applied, it is beneficial to spread the acting force from the center to the periphery, optimizing the overall force received by the pressing portion 21.

[0054] The projection of the pressing member 211 and the projection of the corresponding connector 11 at least partially overlap to ensure that there is enough abutting area between the two, reducing the situation where the local force on the connector 11 is too large.

[0055] As Figures 4 to 9 shown, in the electronic device provided by the present application, each pressing member 211 is connected to the edge of the corresponding opening 221 through a plurality of connecting arms 212, and the plurality of connecting arms 212 are evenly spaced on the periphery of the corresponding pressing member 211 to effectively improve the force uniformity of the pressing member 211.

[0056] Optionally, as Figures 1 to 3 shown, the pressing member 211 can be connected to the main body 22 through four connecting arms 212 to form a cross-shaped structure, which has the advantage of uniform force

[0057] Optionally, as Figure 4 and Figure 5 shown, the pressing member 211 can be connected to the main body portion 22 through two connecting arms 212 to form a linear structure.

[0058] Optionally, as Figure 6 and Figure 7 shown, the pressing member 211 can be connected to the main body portion 22 through only one connecting arm 212 to form a cantilever structure.

[0059] Optionally, as Figure 8 and Figure 9 shown, the opening 221 can be circular, and the pressing member 211 is connected to the main body portion 22 through a plurality of connecting arms 212 to form a petal-shaped structure.

[0060] It should be noted that the number of the connecting arms 212 can be flexibly selected according to actual needs, and the present application is not limited thereto.

[0061] In the electronic device provided by the present application, the main body portion 22 is made of a non-metallic material, for example, formed by plastic injection molding. The connecting arms 212 and the pressing member 211 are both made of a metallic material to ensure their structural strength.

[0062] A positioning member 222 made of a metallic material is embedded inside the main body portion 22, and a part of the positioning member 222 is exposed at the edge of the opening 221, and the connecting arm 212 is connected to the positioning member 222.

[0063] In this way, the bracket 2 structure is made of a combination of non-metallic materials and metallic materials, which can save the amount of metallic materials and achieve the effect of reducing costs.

[0064] As Figure 3 , Figure 5 , Figure 7 and Figure 9 shown, in the electronic device provided by the present application, the main body portion 22, the connecting arms 212 and the pressing member 211 are all made of a metallic material; the main body portion 22, the pressing member 211 and the connecting arms 212 are integrally formed and connected. In this way, the structural strength of the overall structure of the bracket 2 can be effectively ensured.

[0065] Optionally, as Figure 1 , Figure 4 , Figure 6 and Figure 8As shown, the electronic device provided by the present application, wherein the opening 221 is a hole structure with a closed peripheral edge; or the opening 221 is a groove structure recessed at the peripheral edge of the main body 22. The structure of the opening 221 can be adjusted according to the position of the corresponding connector 11. If it corresponds to the middle part of the bracket 2, the opening 221 with a hole structure can be set. If it corresponds to the edge position of the bracket 2, the opening 221 with a groove structure can be set.

[0066] The electronic device provided by the present application, wherein the electronic device further includes a housing. Both the bracket 2 and the circuit board 1 are disposed inside the housing. The housing can protect the bracket 2, the circuit board 1, and various electronic components and connectors 11 disposed on the circuit board 1, and at the same time give the electronic device a complete appearance.

[0067] The bracket 2 and the circuit board 1 are respectively connected to the housing to position the positions of the bracket 2 and the circuit board 1, and to prevent the components inside the housing from shaking during use and affecting the use experience.

[0068] Optionally, the bracket 2 is detachably connected to the housing through a connecting member. The connecting member can be a bolt, a screw, etc.

[0069] Optionally, for the electronic device provided by the present application, a buffer layer is provided on the surface of the pressing member 211 facing the corresponding connector 11. During the process of the pressing member 211 abutting against the connector 11, it is prevented that the pressing member 211 wears the connector 11.

[0070] For the electronic device provided by the present application, by providing a pressing portion on the bracket 2 and making the pressing portion 21 protrude from the surface of the bracket 2 facing the circuit board 1, during assembly, the pressing portion 21 can be made to abut against the corresponding connector 11 to press and position the connector 11; at the same time, since the pressing portion 21 can elastically deform in the direction of approaching or departing from the circuit board 1, it can be designed that after the pressing portion 21 abuts against the connector 11, the pressing portion 21 can generate a small amount of elastic deformation in the direction away from the circuit board 1 to ensure that the pressing portion 21 elastically presses against the corresponding connector 11, ensure the reliable pressing and positioning of the bracket 2 on the connector 11, and ensure the normal use of the electronic device.
