Detailed Description

The advantages of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, a schematic structural diagram of a housing for accommodating electronic components according to a preferred embodiment of the present invention is shown. As can be seen from the figure, the housing includes a first housing 1 and a second housing 2, the first housing 1 is fixedly connected with the second housing 2, and a receiving space is formed inside the first housing 1 and the second housing 2, and the electronic components are received in the receiving space. Preferably, the electronic component should be fixed in the accommodating space, so as to avoid damage to the electronic component accommodated inside due to shaking caused by external force during use. In addition, in the embodiment, at least one limiting portion is further disposed in the first housing 1, and the purpose of this is that, when the first housing 1 is fixedly connected with the second housing 2, the side wall of the second housing 2 is clamped between the limiting portion and the first housing 1. Thereby, can restrict the displacement of second casing 2 with the help of the clamping-force that first casing 1 and spacing portion provided to, in avoiding the use, rocking etc. that external force leads to lead to taking place the displacement between first casing and the second casing and to holding in accommodation space's electronic components's damage.

Referring to fig. 2, which is a schematic structural view of the first housing according to the preferred embodiment of the present invention, it can be seen that in this embodiment, the position-limiting portion 11 may further include an inclined guide surface 111, preferably, the guide surface 111 faces the side wall of the second housing, and preferably, the distance from the guide surface 111 to the side wall of the first housing gradually decreases in the direction from the free end to the fixed end of the position-limiting portion 11. Thus, when the first housing 1 and the second housing 2 are fixedly connected, the side wall of the second housing 2 can slide along the guide surface 111 toward the first housing 1, and at this time, when the difference between the lengths of the first housing 1 and the second housing 2 in the vertical direction of the side wall of the second housing 2 clamped between the first housing 1 and the limiting part 11 is large due to the existence of production error, the side wall of the second housing 2 is clamped at the part of the limiting part near the free end thereof; when the difference between the lengths of the first housing 1 and the second housing 2 in the vertical direction of the side wall of the second housing 2 clamped between the first housing 1 and the limiting portion 11 is small, the side wall of the second housing 2 is clamped at the portion of the limiting portion close to the fixed end thereof. However, it can be seen from the above embodiment that, even if the difference between the first housing 1 and the second housing 2 in length or width, which is caused by the production error, is not equal to the preset difference, the difference error can be compensated by the limiting portion, so that the fastening connection between the first housing 1 and the second housing 2 is reinforced, the first housing is not affected by any external force in the later use process, and the unnecessary damage of the electronic component is avoided.

With reference to fig. 2, based on the above embodiment, another preferred embodiment according to the present invention includes two position-limiting portions 11, the two position-limiting portions 11 are disposed in the length direction of the first housing, and the distance between the two position-limiting portions 11 is the length of the first housing 1 minus twice the thickness of the sidewall of the second housing 2. This is because, in the manufacturing of the housing composed of two housing parts, in order to achieve the ideal situation of the two housings being exactly clamped, the length of the first housing 1 is usually set to be equal to the length of the second housing 2 (neglecting the thickness of the side walls of the two housings), so that, when the two housings are assembled, the first housing can just clamp the second housing to achieve the stable and fixed connection of the two housings without damaging the housings, but in the actual production process, due to the existence of the manufacturing error, the length of the first housing 1 and the length of the second housing 2 are usually greater than or less than the preset length, so that the length of the first housing 1 is greater than the length of the second housing 2, which causes the two housings to move relative to each other, in this case, because the distance between the limiting parts 11 is set to be the length of the first housing 1 minus the thickness of the double side wall of the second housing 2, therefore, the difference generated by the manufacturing error is far smaller than the thickness of the side wall, so that even if the manufacturing error exists, the second shell can still be clamped between the first shell and the limiting part, the relative movement of the second shell is limited by the limiting part and the first shell, and the safe use of the electronic component contained in the second shell is protected.

With reference to fig. 1, based on the above embodiment, in another preferred embodiment consistent with the present invention, a first opening is disposed on the first casing, and a second opening is disposed on the second casing at a position corresponding to the first opening, so that after the first casing is fixedly connected to the second casing, the first opening on the first casing and the second opening on the second casing are combined to form a third opening for disposing the port of the electronic component. Preferably, the outline of the first opening and the outline of the second opening may be set according to the shape of the required port, and after the third opening is obtained by fixedly connecting the first casing and the second casing, the port may be clamped in the third opening, so that the electronic component to be protected is stably protected in the accommodating space, and the port is exposed to the outside so as to be electrically connected or communicatively connected with an external power supply or a device.

Based on above-mentioned embodiment, accord with the utility model discloses a in another preferred embodiment, first casing 1 passes through the buckle with second casing 2 and is connected to, the holistic aggregate erection of casing of not only being convenient for, still convenient for dismantle at any time in the use, with the maintenance or the change etc. of realization to inside electronic components. However, it should be understood that the first housing and the second housing in the present invention are not limited to being fixedly connected by means of a snap-fit, and the connection means such as riveting, welding, gluing, and fastening screws are also applicable to the embodiments of the present invention.

Based on above-mentioned embodiment, accord with the utility model discloses a another preferred embodiment, still be provided with buckle 12 on the first casing 1, the position that corresponds this buckle 12 on the second casing is provided with trip 22, and during the installation, trip 22 card is held in buckle 12, realizes that first casing 1 is fixed in 2 on the second casing. Thereby, a stable connection of the first housing 1 and the second housing 2 is achieved, while at the same time a convenient detachment when needed.

Based on the above embodiment, accord with the utility model discloses in another preferred embodiment, be provided with the fixed bolster on first casing or the second casing, be used for the fixed casing extremely on the waiting mounted position of casing. It should be understood that the specific location and configuration of the mounting bracket may be configured accordingly to the needs of the connection to the external structure.

With reference to fig. 1, based on the above embodiment, in another preferred embodiment consistent with the present invention, the housing contains a PCB board 3, the PCB board 3 is used for fixedly connecting electronic components, and the electronic components are electrically connected to an external battery or device through a port 31 disposed on the PCB.
