Description

Technical Field

[0001] The present invention belongs to the technical field of lateral capacitors, and in particular relates to a lateral capacitor fixing bracket and a device thereof. Background Art

[0002] With the development of science and technology, in-vehicle tablet computers have emerged. In-vehicle tablet computers refer to in-vehicle computers in tablet form, with touch screens and buttons as basic input devices. In-vehicle tablet computers are highly integrated devices that support in-vehicle Internet access, audio and video entertainment, satellite positioning, voice navigation, games, phone calls and other functions.

[0003] When using a car tablet, there are generally many functional requirements. In addition to the number of common serial ports, USB ports, and network ports, the following specifications are particularly sensitive:

[0004] (1) Anti-seismic requirements: There is no need to explain the vehicle environment. Any vehicle will generate vibrations. Depending on the user, there are high acceleration and large amplitude, and low acceleration and small amplitude.

[0005] (2) Display requirements: Since the vehicle is used outdoors, it is inevitable to be exposed to deflected or even direct sunlight. It is necessary to minimize the impact of this situation by selecting high-quality displays or structural designs.

[0006] (3) Power performance: Car computers generally draw power directly from the car battery. Due to the different usage conditions of various batteries and the instantaneous impact of ignition and shutdown, the power requirements of the equipment used in conjunction are very high. Otherwise, it is very easy to damage the equipment, and the tablet screen will vibrate violently and freeze, and restart. Based on this requirement, it is very necessary to add capacitors on its circuit board or bring external batteries to store power.

[0007] (4) Wide temperature and voltage requirements: Most of my country is located in the subtropical and temperate zones. The country has a vast territory and the temperature environment of vehicles is extreme, ranging from -30 to 70 degrees Celsius. This is a test for vehicle-mounted equipment.

[0008] (5) Electromagnetic interference: It is impossible for a special vehicle to be used with only one electrical device. Unqualified electromagnetic radiation will cause serious interference to other equipment, such as digital radio stations, medical high-precision vital sign monitoring, etc.

[0009] (6) Function buttons: The function buttons can bring great convenience and improve the efficiency of use in an unstable in-car environment.

[0010] However, during the displacement process of the current circuit board with capacitors, the capacitors are in a cantilever stress state and are easily damaged, resulting in functional disorders.

[0014] In one of the embodiments, the outer surface of the first side wall extension portion extends outward to form a buckle, and the lower surface of the first side wall extension portion extends downward to form a welding portion; the outer surface of the second side wall extension portion extends outward to form a buckle, and the lower surface of the second side wall extension portion extends downward to form a welding portion; the A side wall is provided with a slot to cooperate with the buckle of the first side wall; the B side wall is provided with a slot to cooperate with the buckle of the second side wall; one end of the bottom wall extends outward to form a limiting spring sheet, and the limiting spring sheet is located between the first side wall and the second side wall, and is passively buckled by bending the spring sheet to elastically limit the capacitor; the middle part of the bottom wall is tilted upward to form a U-shaped spring sheet, and is passively buckled by bending the spring sheet to elastically limit the capacitor; the end of the C side wall away from the top wall extends outward to form a spring sheet.

[0015] In one embodiment, the first side wall is formed by extending along the edge of one side of the bottom wall; the second side wall is formed by extending along the edge of the other side opposite to the one side of the bottom wall; the A side wall is formed by extending along the edge of one side of the top wall; the B side wall is formed by extending along the edge of the other side opposite to the one side of the top wall; and the C side wall is formed by extending along the edge of a side adjacent to the one side of the top wall.

When it is subjected to external force, the plurality of brackets can protect the plurality of capacitors.

[0018] In the case of any displacement of the circuit board or other environments requiring movement, the bracket acts as a fixed protection. It is understandable that, especially when the device is in a vehicle transportation environment, several capacitors need to be more stable and firm, so the device provided by the present invention is particularly suitable for vehicle transportation environments.

[0019] In one embodiment, a card hole is provided on the first side wall of the first shell of each of the side-standing capacitor fixing brackets, and a card is provided on the second side wall of the first shell of each of the side-standing capacitor fixing brackets. With such a design, the card on the second side wall of the first shell of one of the side-standing capacitor fixing brackets is inserted into the card hole on the first side wall of the first shell of an adjacent side-standing capacitor fixing bracket, and at the same time, the card hole on the first side wall of the first shell of the side-standing capacitor fixing bracket accommodates the card on the second side wall of the first shell of another adjacent side-standing capacitor fixing bracket, so that the first shells of several side-standing capacitor fixing brackets are assembled together.

[0020] In one embodiment, a first clip portion is provided at one end of the A side wall on the C side wall of the second shell of each of the side-standing capacitor fixing brackets, and a second clip portion is provided at one end of the B side wall on the C side wall of the second shell of each of the side-standing capacitor fixing brackets.

In this way, after the device is produced, the capacitor is subjected to vibration force by the bracket during the production and transportation of the device. During the vibration, the spring sheet acts as a buffer structure and plays a buffering and protective role. In addition, during the production of the device, the bracket can be used as a production jig for fixed capacitors, thereby increasing the board yield and production efficiency.

[0022] In one of the embodiments, the welding portion of the second side wall extension portion of the first shell of each of the side-standing capacitor fixing brackets is a harpoon-shaped pin, which is used for limited welding after the bracket passes through the circuit board.

[0058] Please also read Figures 5 to 8 , which is a three-dimensional diagram 200 of a device with a side-standing capacitor fixing bracket provided by an embodiment of the present invention.

[0059] The device 200 with a side-standing capacitor fixing bracket includes a circuit board 300, a plurality of capacitors 400 mounted on the circuit board 300, and a plurality of side-standing capacitor fixing brackets 100 as described above; the plurality of capacitors 400 are respectively accommodated in a plurality of the side-standing capacitor fixing brackets 100, so as to form a whole with uniform force. When subjected to external force, the plurality of side-standing capacitor fixing brackets 100 can protect the plurality of capacitors 400.

[0060] When the circuit board 300 is displaced or in other environments where movement is required, the bracket acts as a fixed protection. It is understandable that, especially when the device 200 is in a vehicle transportation environment, several capacitors need to be more stable and firm, so the device 200 provided by the present invention is particularly suitable for vehicle transportation environments.

[0061] Furthermore, a card hole 28 is provided on the first side wall 11 of the first shell 1 of each of the side-standing capacitor fixing brackets 100, and a card 29 is provided on the second side wall 12 of the first shell 1 of each of the side-standing capacitor fixing brackets 100.

In this way, after the production of the device 200 is completed, during the production and transportation of the device 200, the capacitor is subjected to vibration force by the bracket, and during the vibration, the spring piece serves as a buffer structure and plays a buffering and protective role. In addition, during the production process of the device 200, the bracket can be used as a production jig for fixing the capacitor, thereby increasing the board production yield and production efficiency.

[0065] Specifically in this embodiment, the number of the plurality of lateral capacitor fixing brackets is 3, and the 3 lateral capacitor fixing brackets can be compatible with capacitors with the same diameter and various lengths.

[0066] Specifically in this embodiment, the number of the plurality of capacitors is 3, and the 3 side-standing capacitor fixing brackets can be compatible with supercapacitors of the same diameter but different lengths.

[0067] It can be understood that the number of the plurality of side capacitor fixing brackets and the number of the plurality of capacitors can be combined according to the number of device requirements, which facilitates the production of the circuit board and increases stability.

[0068] The present invention has at least the following advantages:

[0069] (1) Increase the fixation and fitting accuracy of capacitor patches. The bracket can be used as a production jig to increase the board yield and production efficiency.

[0070] (2) The bracket acts as a fixed protection when the circuit board is displaced or in other environments where movement is required.

[0071] (3) When the device is applied to a terminal product such as a vehicle-mounted tablet computer, the bracket can provide shockproof protection for the capacitor in the vehicle-mounted tablet computer's use environment.

[0072] (4) When a number of capacitors are produced, the bracket provided by the present invention can be pieced together into an integral structure and assembled as a whole, thereby increasing strength and production consistency.

[0073] (5) For supercapacitors with the same diameter, such as a diameter of D=8 or a diameter of D=6, the bracket can provide fixation for supercapacitors of different lengths.

[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
