[0041] The term “connection” as used in this application may mean a direct connection between components or an indirect connection between components via other components.

[0042] like Figure 1-8 As shown, the present application is a self-powered positioning terminal protection box, which is composed of an outer shell and an inner box. The inner box includes an inner box shell 1, and the inner box shell 1 is provided with:

[0043] An energy collector placement area 2, in which an electromagnetic energy collector is detachably installed, a support structure placement area 3 is provided at the bottom of the energy collector placement area 2, and a support structure is provided in the support structure placement area 3; a push-pull partition groove 4 is provided at the upper part of the energy collector placement area 2, in which a push-pull partition is detachably installed, and the push-pull partition and the support structure fix the electromagnetic energy collector from the upper part and the lower part respectively;

[0044] A PCB board placement area 9, in which a PCB board is detachably mounted;

[0045] A metal sheet track 6, one end of which is located at the support structure placement area 3, and the other end of which is located at one side of the PCB board placement area 9, so as to electrically connect the electromagnetic energy collector to the PCB board;

[0046] A battery placement area 8, in which a power source is detachably mounted;

[0047] The antenna placement area 7 has an antenna detachably mounted therein.

[0048] The energy collector placement area 2 includes a plurality of energy collector placement areas 2 arranged along the periphery of the inner box shell 1, and each energy collector placement area 2 has a metal sheet track 6 extending from its bottom plate.

[0049] The energy collector placement areas 2 are arranged into a first row distributed along the inner side of the inner box shell 1 and a second row distributed along the outer side of the inner box shell 1; the PCB board placement area 9 is located between the two rows of energy collector placement areas 2, and is arranged close to the energy collector placement area 2 on one side; in the two rows of energy collector placement areas 2, the two energy collector placement areas 2 adjacent to the PCB board placement area 9 are respectively set to have openings in a first direction, and the other energy collector placement areas 2 are respectively set to have openings in a second direction; wherein the first direction is parallel to the direction in which the metal sheet track 6 enters the PCB board placement area 9, and the openings in the second direction are perpendicular to the first direction and are respectively set to be open to the center of the inner box shell 1; the installation directions of the push-pull partition grooves 4 in the energy collector placement areas 2 are the same as the second direction.

[0050] The push-pull partition groove 4 is transversely arranged on the upper part of the energy collector placement area 2 , and the projection area of ​​the push-pull partition groove 4 is not less than the projection area of ​​the energy collector placement area 2 .

[0051] Specifically, the energy collector placement area 2 arranged in the inner box is distributed in an array, and the specific structure and position are as follows: Figure 2As shown. The interior of the inner box is equally divided into six partitioned spaces, each of which has a cylindrical storage frame that matches the size and shape of the electromagnetic energy collector, namely, the energy collector placement area 2, so as to realize the placement of multiple electromagnetic energy collectors. The fixation of the electromagnetic energy collector in the cylindrical storage frame is achieved by the two structures of the support structure placement area 3 and the push-pull partition groove 4. First, a metal gasket or a small spring can be placed in the support structure placement area 3 to support the electromagnetic energy collector; after the electromagnetic energy collector is stabilized, a rectangular push-pull partition that matches the push-pull partition groove 4 is placed in the groove, thereby limiting the vertical movement of the electromagnetic energy collector so that it can be stably fixed in the area. If the electromagnetic energy collector needs to be replaced during the test, this method can easily complete the operation. The schematic diagram after placing the rectangular push-pull partition is shown as follows Figure 3 As shown. This placement and fixing method can ensure that different electromagnetic energy collectors do not interfere with each other and ensure high charging and discharging efficiency. At the same time, during use, the array distance and storage frame shape of the area can be adjusted according to the actual number and shape of the electromagnetic energy collectors.

[0052] There are three energy collector placement areas 2 in each row, among which the energy collector placement areas 2 on the left and the middle are opened downward, and the energy collector placement area 2 on the right is opened to the left, and the side of the structure where the energy collector placement area 2 on the right is located close to the center of the inner box shell 1 is set as a partition structure, and a push-pull partition groove 4 passes through the partition and is arranged on the upper part of the energy collector placement area 2 on the right, and the push-pull partition groove 4 of the energy collector placement area 2 on the right is set in the same direction as the push-pull partition groove 4 of the left and middle energy collector placement areas 2.

[0053] The PCB board placement area 9 and the battery placement area 8 are located in the middle of the two energy collector placement areas 2 set on the right side. The battery placement area 8 is embedded below the bottom of the PCB board placement area 9, and the two are arranged up and down. The size of both can be customized according to the actual application scenario. The vertical space is fully utilized by the up and down arrangement. This design can greatly reduce the length of the outer shell. In order to allow the PCB board to be fixed inside the inner box, raised threaded holes are set around the PCB board placement area 9, and bolts are used to facilitate loading and unloading. There is enough distance between the four raised threaded holes and the six electromagnetic energy collector cylindrical storage frames, whether up and down or left and right. This design can meet the requirements of using an external PCB plug-in connector to connect each electromagnetic energy collector to the PCB board.

[0054] Two support structure placement areas 3 are set in each energy collector placement area 2, and each support structure placement area 3 is respectively connected to one end of the metal sheet track 6, and the other end of the metal sheet track 6 is connected to the left side of the PCB board placement area 9; there is a gap between the metal sheet tracks 6. Each electromagnetic energy collector has two endpoints that need to be connected to the PCB board, so there are a total of 12 metal sheet tracks in the inner box. Regardless of whether it is connected by wires or conductive sheets, the track can ensure that there is enough space in the inner box for them to be arranged neatly, and they will not affect each other. The specific structure of the metal sheet track 6 is as follows Figure 5 shown.

[0055] The inner box shell 1 is a drawer-type structure, and its front end structure is a vertical cover plate. The antenna placement area 7 is arranged on the inner side of the cover plate; other structures on the inner box shell include a PCB board placement area 9, a metal sheet track 6, and a battery placement area 8, which are all arranged on the rear end horizontal structure part of the inner box shell 1. The antenna placement area 7 is in the shape of a rectangular groove, and the position of the antenna placement area 7 is relative to the energy collector placement area 2, in the middle of the second row of energy collector placement areas 2 on the outside and between the two energy collector placement areas 2 on the right. The specific diagram is as follows Figure 6 The antenna placement area 7 can accommodate the antenna, and its height is less than the height of the cover plate, so that the antenna can be embedded without affecting the matching installation. At the same time, this position is located on the front surface of the entire protective shell, and the surface is flat without metal covering to ensure that the signal transmission is less interfered and further improve the positioning accuracy.

[0056] The four corners of the cover plate are provided with positioning and mounting holes 5. The positioning and mounting holes 5 are symmetrically distributed. The holes are designed as M6 hexagonal countersunk threaded holes, so that there is no protruding screw head on the front surface of the inner box. This design is not easy to cause buckling, wear or difficulty in tightening during installation. It enhances the aesthetics while ensuring the reliability of connection and reducing the difficulty of assembly. The specific structure is as follows: Figure 4 shown.

[0057] In addition to the above structure, in order to enable the inner box to flexibly move forward and backward in the outer shell, fillets with a certain arc are set at the connection between the two side surfaces of the inner box and the rear surface.

[0058] The shell includes a shell body 10, which is a trihedral structure with a hollow interior and a front opening that matches the shape of the inner box shell 1. Positioning threaded holes 11 are provided at the four corners of the front end of the shell body 10 corresponding to the positions of the positioning and mounting holes 5. The positioning and mounting holes 5 are connected to the positioning and mounting threaded holes 11 by bolts. The lower surface of the shell is provided with a plurality of through holes 12 with a plurality of circumferences of different diameters, and a rectangular groove 13 with a height greater than the through hole 12 is provided above the through hole 12, which is used to connect the shell with other parts.

[0059] The schematic diagram of the shell structure is as follows Figure 7 As shown, the four corners of the outer shell are rounded to avoid collision loss and improve safety. There are four symmetrically distributed M6 threaded holes 11 on the front surface, which can be installed with the inner box. The bolt connection method allows the self-powered positioning terminal device to withstand high-strength and high-load occasions, and is convenient for subsequent maintenance. In order to achieve the positioning and installation coordination with the train bogie or other mechanical parts in the installation position, the lower surface of the outer shell 10 is respectively distributed with a diameter of 40, 60, 80, and 120 mm. A plurality of through holes 12 with a diameter of 5 mm and a height of 4 mm are distributed on the circumference, and a rectangular groove 13 with a height of 6 mm is opened above these holes. The purpose of this design is to facilitate the use of nuts and screws to connect the outer shell and other parts. When fixing the outer shell, the lower surface of the outer shell needs to be in close contact with the outer surface of other parts, and then a screw of appropriate length is placed inside the positioning through hole 12, and the nut is also installed inside the rectangular groove 13. This connection method using nuts and screws can flexibly adjust the outer shell 10 to the most convenient position and angle, and is easy to assemble, thereby ensuring the stability of the working environment of the internal self-powered positioning device.

[0060] Specifically, the overall size of the protective shell of the present application is 260mm×147mm×82mm. By adopting the above technical solution, after the electromagnetic energy collector, antenna, PCB board and other equipment are installed and fixed to the corresponding area of ​​the inner box, the inner box can be flexibly pushed to the hollow area of ​​the outer shell, and after moving to the front end, only four hexagon socket countersunk screws of appropriate length are needed to fix the two, which improves the ease of installation and the convenience of subsequent maintenance.

[0061] Those skilled in the art can understand that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents.
