In addition, some well-known parts may not be shown.

[0031] It should be understood that when describing the structure, when a component or a module is referred to as being "before" another component or another module, it may mean directly in front of and connected to the circuit of the other component or another module, or there may be other components or modules between it and the other component or another module.

[0032] If it is to describe the situation of being directly before another component or another module, the expressions "directly before..." or "before and adjacent to..." will be used in this article.

[0033] Many specific details of some embodiments of the present utility model are described below, such as the specific circuit composition of the module, the component models, quantities, and connection relationships, in order to understand the present utility model more clearly. However, as those skilled in the art can understand, the present utility model can be implemented without these specific details.

[0034] The present utility model can be presented in various forms, and some examples will be described below.

[0035] Figure 1The explosion diagram of the controller according to the embodiment of the present invention is shown. The controller includes a bottom plate 100, an upper cover 200, a circuit board 300, and a baffle 400. Among them, the bottom plate 100 is, for example, a plate-shaped with rounded corners, and further, the bottom plate 100 is, for example, an aluminum plate, and its upper surface is, for example, also provided with a plurality of pits to avoid corresponding devices on the back of the circuit board 300; the upper cover 200 includes, for example, a top surface and four surrounding side walls connected to the top surface. A first opening is provided on one side wall of the upper cover 200. The upper cover 200 is, for example, made of plastic and is integrally formed; the upper cover 200 and the bottom plate 100 are, for example, connected by a bolt 1, and the bolt 1 passes through a through hole 130 on the bottom plate 100 from below the bottom plate 100 to be connected to the upper cover 200. The upper cover 200 and the bottom plate 100 are combined to form a cavity with a first opening on one side, and the circuit board 300 is located in this cavity. The circuit board 300 has a number of interfaces 310 on the side of the first opening of this cavity. The interfaces 310, for example, partially extend beyond the edge of the circuit board 300. The baffle 400 is, for example, located at the first opening of this cavity. The baffle 400 has a second opening 410 corresponding to the interface 310 of the circuit board 300. The side of the baffle 400 facing the bottom plate 100 has a bend towards the cavity side to form a connection structure, and this connection structure is, for example, a lug 420. The bottom plate 100 has a connection part corresponding to the lug 420 and the side of the baffle 400. Specifically, this connection part is a first card slot 110. The lug 420 is, for example, perpendicular to the plane where the second opening 410 is located. The lug 420, for example, includes two, and both have through holes 421. The bolt 4 passes through the through holes 421 to fix the baffle 400 in the first card slot 110 of the bottom plate 100. The circuit board 300 has through holes 320 for fixing, and the bottom plate 100 is provided with a corresponding number of stud connection holes 120. A plurality of studs 2 are connected to the bottom plate 100 through the stud connection holes 120. The bolt 3 passes through the through holes 320 of the circuit board 300 to be connected to the top of the stud 2, so that the circuit board 300 is relatively fixed to the bottom plate 100, and the circuit board 300 is suspended on the bottom plate 100 through the stud 2. Specifically, the stud 2, for example, includes 4. This design can not only enhance the heat dissipation capacity of the circuit board 300, but also prevent the interface 310 of the circuit board 300 from being too close to the bottom plate 100, making it more convenient for plugging and unplugging.

[0036] Further, all interface devices are, for example, arranged on the front side of the circuit board 300. The front side of the circuit board 300 is, for example, also provided with a second interface 330 perpendicular to the plane of the circuit board 300. Correspondingly, the top cover 200 also has a corresponding limit port 220. Specifically, the second interface 330 perpendicular to the plane of the circuit board 300 can be used to connect to sensors such as lidar, which will not be elaborated here.

[0037] Figure 2The figure shows a schematic diagram of the bottom plate and the upper cover in the controller of the embodiment of the present utility model; in order to better show the connection between the bottom plate 100 and the upper cover 200, Figure 2 The controller is flipped so that the bottom plate 100 is located above and the upper cover 200 is located below. Specifically, the bottom plate 100 has a through hole 130, and the upper cover 200 has a connection hole 210 corresponding to the through hole 130. One end of the bolt 1 passes through the through hole 130 from one side of the bottom plate 100 and is connected to the connection hole 210 of the upper cover 200, thereby fixedly connecting the bottom plate 100 and the upper cover 200. Further, the through hole 130 is, for example, a stepped hole, and the nut at the top of the bolt 1 can be completely sunk into the step of the through hole 130 to prevent it from protruding from the bottom surface of the bottom plate 100, ensuring that the bottom surface of the bottom plate 100 is flat without protruding structures.

[0038] Figure 3 The figure shows a schematic diagram of the controller of the embodiment of the present utility model after removing the upper cover; as can be seen from Figure 3 it, the circuit board 300 is connected to the bottom plate 100 through the stud 2. Since the stud 2 has a certain height, the back surface of the circuit board 300 can be suspended relative to the bottom plate 100, that is, components can be mounted on both the front and back sides of the circuit board 300. Further, some components on the back surface of the circuit board 300 are relatively high, and corresponding pits are provided on the bottom plate 100 for avoidance to prevent interference. The circuit board 300 is provided with a plurality of first interfaces 310 on one side of the first opening of the cavity, and the baffle 400 at the first opening is provided with a plurality of second openings 410 corresponding to the plurality of first interfaces 310, for example.

[0039] Figure 4 The figure shows a schematic diagram of the combination of the bottom plate and the baffle in the controller of the embodiment of the present utility model; it can be seen from the markings on the baffle 400 that the interfaces 310 of the circuit board 300 include a power supply interface and a data transmission interface; the data transmission interface includes: a video transmission interface, a network interface, an antenna interface, a programming interface, etc.

[0040] Figure 5 The figure shows a schematic diagram of the installation of the baffle of the controller of the embodiment of the present utility model; as can be seen from Figure 5As can be seen, the bottom plate 100 is provided with a plurality of pits 130 on the side facing the circuit board 300 to avoid the components on the back of the circuit board 300. The bottom plate 100 is also provided with a first card slot 110 corresponding to the lower side edge and the lug 420 of the baffle 400 at the first opening. The first card slot 110, as a connecting part, can make at least a part of the lower side edge area of the baffle 400 be embedded into the first card slot 110, making its connection more stable. For example, there are two lugs 420, which are formed by bending. The lugs 420 are perpendicular to the plane where the second opening 410 of the baffle 400 is located. The lugs 420 also have through holes 421. The baffle 400 is connected to the bottom plate 100 by bolts 4 passing through the through holes 421. Further, in order to reduce the influence on the plane where the second opening 410 of the baffle 400 is located caused by bending to form the lugs 420, a notch 422 is provided at the root of the lugs 420. The notch 422 is beneficial to the plane where the second opening 410 of the baffle 400 remains unchanged after bending, reducing the influence on the second opening 410, so that the second opening 410 can better match the first interface 310.

[0041] Further, the depth of the first card slot 110 is, for example, slightly greater than the depth of the notch 422, so that the notch 422 is blocked by the bottom plate 100, and the shape of the first card slot 110 of the bottom plate 100 is consistent with the contour of the lower side part of the baffle 400, making it easier to assemble.

[0042] Figure 6 Fig. shows a schematic diagram of the cooperation between the baffle and the upper cover in the controller according to the embodiment of the present invention; as can be seen from Figure 6 As can be seen, the upper cover 200 is provided with second card slots 220 at positions corresponding to the left and right sides of the baffle 400. During connection, the side edges of the baffle 400 can slide into the second card slots 220 to ensure the stability of the connection between the baffle 400 and the upper cover 200. Further, in order to prevent the baffle 400 from shaking, the inner side of the second card slot 220 has an inclined surface design. The depth of the second card slot 220 gradually decreases from the end 221 close to the bottom plate 100 to the end 222 far from the bottom plate 100, so that the second card slots 220 on the left and right sides are trapezoidal. When the baffle 400 slides into the second card slot 220, it will become tighter and tighter, ensuring that the baffle 400 is stable and does not shake, strengthening the overall structural strength and making it more drop-resistant.

[0043] Figure 7The figure shows a schematic diagram of the controller according to an embodiment of the present utility model. After assembly, the bottom plate 100 is connected to the upper cover 200, and the circuit board 300 in its internal cavity is blocked and invisible. One side of the upper cover 200 has a first opening, and the baffle 400 is located at this first opening. The lower side area of the baffle 400 is embedded in the first card slot 110 of the bottom plate 100 and is connected to the bottom plate 100 by bolts. The left and right side edges of the baffle 400 are connected and fixed to the second card slots of the upper cover 200; the limiting openings on the baffle 400 correspond to the interfaces of the circuit board 300. The controller in this embodiment is, for example, a navigation controller of an automated guided vehicle, but is not limited thereto.

[0044] For the controller provided by the present utility model, by providing a baffle and arranging a second opening corresponding to the circuit board interface on the baffle, the problem that the connector is sunken in the outer surface is solved, and it can effectively reduce the poor contact caused by the connector not being inserted to the bottom when being inserted. Further, the baffle is connected to the bottom plate through a fixing structure and is connected to the upper cover through a second card slot. Its connection structure is firm and has good anti-drop performance. The connection part provided on the bottom plate and matching the baffle can effectively position the baffle, making its assembly more convenient.
