Detailed Description of the Embodiment

[0038] The following further describes the present application in detail with reference to the attached Figures 1-3 drawings.

[0039] A portable data acquisition device disclosed in an embodiment of the present application, referring to Figure 1 and Figure 2 , the portable data acquisition device includes a box body 1, a host 5 and a display screen 4; the box body 1 is used to accommodate a law enforcement recorder, and after the host 5 receives the data collected by the law enforcement recorder, it is analyzed and sorted by each module and then displayed through the display screen 4.

[0040] The box body 1 includes an approximately U-shaped outer frame 11 and a bottom plate 12 detachably connected to the bottom of the outer frame 11. The outer frame 11 and the bottom plate 12 form a box shape with openings at the top and one side end.

[0041] Referring to Figure 1 and Figure 2, a main board 2 and a collection rack 3 are also detachably connected inside the outer frame 11. The main board 2 is a circuit board and is communicatively connected to the host 5 through a data cable. A plurality of data transmission interfaces are provided on the main board 2, and each data transmission interface is connected to a data collection line 33. The data collection line 33 can be used to connect to a law enforcement recorder. While charging the law enforcement recorder, the data in the law enforcement recorder can be collected. The collection rack 3 is formed with a plurality of collection slots 31, and the plurality of collection slots 31 are arranged in a rectangular array. One end of each data collection line 33 is respectively inserted into a collection slot 31 and can be used to connect to the law enforcement recorder placed in the collection slot 31. In this embodiment, the end of the data collection line 33 connected to the main board 2 is set as a USB interface, and the end connected to the law enforcement recorder is set as a type-c interface. In other embodiments of the present application, the data collection line 33 can also be set according to the specific interface structures of the main board 2 and the law enforcement recorder. A part of the data collection line 33 located in the collection slot 31 is set as an elastic spiral line, so as to facilitate pulling the data collection line 33 to adjust the position of the type-c interface and facilitate connection to the law enforcement recorder.

[0042] Refer to Figure 2 and Figure 3 , a support edge 113 is fixed at the bottom of the inner wall of the outer frame 11, and the bottom of the main board 2 abuts against the support edge 113. The support edge 113 provides a support force for the main board 2. At this time, the outer frame 11 provides a clamping force for the side surface of the main board 2, thereby fixing the main board 2. A plurality of abutment grooves 114 are also formed in the inner wall of the outer frame 11, and the abutment grooves 114 penetrate through one end of the outer frame 11 away from the bottom plate 12. The collection rack 3 includes sliding parts respectively and slidably connected in the abutment grooves 114. The sliding parts are convex parts on the side surface of the collection rack 3. By sliding the sliding parts to the bottom of the abutment grooves 114, the position of the collection rack 3 can be positioned. The collection rack 3 does not interfere with the main board 2, and there can be a space for the data collection line 33 to move between the collection rack 3 and the main board 2. The outer frame 11 is made of elastic aluminum alloy. After being fixed at the side opening end of the outer frame 11, the elastic force of the outer frame 11 can also be used to clamp the collection rack 3 to limit the movement of the collection rack 3.

[0043] The bottom plate 12 is detachably connected to the support edge 113 through a second connecting member. Specifically, the second connecting member can be a bolt, a screw, etc. Four corner positions on the surface of the bottom plate 12 away from the main board 2 are threadedly connected with support feet 122. When the box body 1 is placed on the table, the support feet 122 abut against the table to provide support for the box body 1, reducing the interference between the second connecting member and the table. Since the support feet 122 are threadedly connected to the bottom plate 12, if the table is uneven or tilted, the support feet 122 can be rotated to adjust to keep the box body 1 level. An operation groove 121 is recessed in the surface of the bottom plate 12 away from the main board 2. When using the data acquisition device and needing to move the position, setting the operation groove 121 can make it more convenient for the operator to lift and move the data acquisition device.

[0044] Refer to Figure 1 and Figure 2 , the host 5 is located inside the box body 1 and near the side opening position of the outer frame 11. The outer frame 11 has two opposite connecting edges 111 at the side opening position. When the host 5 is installed inside the box body 1, one side of the host 5 abuts against the connecting edge 111, and the host 5 is connected to the connecting edge 111 through a first connecting member. Specifically, the first connecting member can be a bolt and a screw, etc. After the host 5 is connected to the connecting edge 111 through the first connecting member, the outer frame 11 can clamp the main board 2, the host 5 and the acquisition rack 3 at the same time.

[0045] Refer to Figure 1 and Figure 2 , when the display screen 4 rotates to abut against the host 5, the angle of the display screen 4 is fixed and is the maximum rotation angle. By increasing the rotation damping force of the display screen 4, the display screen 4 can be rotated to different angles and then fixed, improving the applicability. The above can be realized by a conventional structure and will not be elaborated in this application. A sliding groove is formed on the side surface of the display screen 4, and a lock 41 is slidably connected in the sliding groove. The lock 41 can move and reset through a spring arranged in the sliding groove. Correspondingly, a lock hole 112 for inserting the lock 41 is formed on the outer frame 11. When the display screen 4 is rotated to close the top opening of the box body 1, the lock 41 moves into the sliding groove through the thrust of the inner wall of the outer frame 11. When the display screen 4 covers the top opening of the box body 1 and the positions of the sliding groove and the lock hole 112 correspond, the lock 41 is moved by the elastic force of the spring to be inserted into the lock hole 112. At this time, the rotation friction force of the display screen 4 can be increased to reduce the possibility of the display screen 4 rotating automatically. A handle 52 is bolted to the surface of the host 5 abutting against the connecting edge 111, which is convenient for the operator to carry the data acquisition device by hand.

[0046] A hard disk holder 51 is also detachably and slidably connected to the side wall of the main unit 5, and a relief hole 115 for the hard disk holder 51 to slide is provided on the corresponding outer frame 11. The hard disk holder 51 can be used to place a hard disk. After the hard disk holder 51 is connected to the main unit 5, the hard disk can be communicatively connected to the main unit 5. By providing the relief hole 115, it is convenient to slide the hard disk holder 51 to insert or remove the hard disk.

[0047] The implementation principle of a portable data acquisition device according to an embodiment of the present application is as follows: By dividing the data acquisition device into components such as an outer frame 11, a bottom plate 12, a main board 2, an acquisition rack 3, and a display screen 4, it is convenient to carry out production separately, reducing the production difficulty, and can be assembled manually or on an assembly line according to specific installation steps, improving production efficiency. And during installation, after positioning and assembling each component, it can be locked through the first connecting piece and the second connecting piece. The main board 2 and the acquisition rack 3 are fixed by the clamping force of the outer frame 11, making the installation more convenient.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
