For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0036] like Figures 1 to 15 As shown, the embodiment of the present application provides a navigation controller, which includes: a housing, including an upper housing 10 and a lower housing 30, the upper housing 10 includes an upper housing body 11, a protection portion 12 and a plurality of connection portions 13, the protection portion 12 is arranged to protrude from the first side wall 14 of the upper housing body 11 along the first direction X; an integrated circuit board 20 is detachably installed between the upper housing 10 and the lower housing 30, the edge of the integrated circuit board 20 is connected to a connector 21, and the connector 21 is at least partially arranged to protrude from the first side wall 14 of the upper housing body 11; a plurality of inner recesses 111 are formed at intervals on the circumference of the upper housing body 11, the plurality of inner recesses 111 are formed by the outer contour edge of the upper housing body 11 being recessed toward the center, two of the plurality of inner recesses 111 are arranged symmetrically about the center of the protection portion 12 along the first direction X, and the plurality of connection portions 13 are arranged in the plurality of inner recesses 111 accordingly. Wherein, the first direction X and the second direction Y are arranged perpendicular to each other.

[0037] In a specific implementation, the navigation controller of the present application includes a shell and an integrated circuit board 20, the shell includes an upper shell 10 and a lower shell 30, the integrated circuit board 20 is detachably installed between the upper shell 10 and the lower shell 30, the edge of the integrated circuit board 20 is connected to a connector 21, at least part of the connector 21 protrudes from the first side wall 14 of the upper shell body 11, and is used to connect with external electrical signals or communication signals, the upper shell 10 includes an upper shell body 11, a protective portion 12 and a plurality of connecting portions 13, the protective portion 12 protrudes from the first side wall 14 along a first direction X, and can be covered on the connector 21 to prevent the protruding connector 21 from colliding with the vehicle In order to prevent the collision with other parts or human body inside the vehicle, a plurality of recessed portions 111 are formed at intervals on the periphery of the upper shell body 11. The recessed portions 111 are formed by the outer contour edge of the upper shell body 11 being recessed toward the center, which can reduce the overall weight and volume of the upper shell body 10. Two of the plurality of recessed portions 111 are symmetrically arranged about the center of the protection portion 12, and a plurality of connecting portions 13 are correspondingly arranged in the plurality of recessed portions 111, so that the protection portion 12 and the connecting portion 13 are prevented from excessively protruding from the outer contour edge of the upper shell body 11, thereby preventing the collision with other parts or human body inside the vehicle, thereby ensuring the overall lightweight of the navigation controller while also meeting its safety requirements.

[0038] Specifically, the integrated circuit board 20 is a PCBA (Printed Cirruit Board Assembly), that is, a printed circuit board. The integrated circuit board 20 in the embodiment of the present application can perform inertial navigation on the vehicle and has the function of improving the positioning and navigation of autonomous driving.

[0039] Specifically, along the first direction X, the protruding length of the protection portion 12 can be greater than the protruding length of the connector 21, and along the second direction Y, the width of the protection portion 12 is greater than the width of the connector 21, that is, the protection portion 12 can completely cover to prevent other structures in the vehicle from colliding with the connector 21, thereby causing damage to the connector 21.

[0040] like Figures 3 to 9 As shown, the navigation controller of the embodiment of the present application, wherein the connecting part 13 is a plate-like structure, each connecting part 13 has a mounting hole 131 arranged therethrough, the navigation controller is connected to the external structure via the mounting hole 131 of the connecting part 13, and there is a first spacing D1 between the axis of the mounting hole 131 and the outer contour edge of the upper shell body 11, and the first spacing D1 has the following range: D1 ≥ 10 mm.

[0041] In specific implementation, the connecting portion 13 of the plate-like structure is light in weight, which can reduce the overall weight of the navigation controller and achieve overall lightweight; the setting of the mounting hole 131 facilitates the installation of the navigation controller inside the vehicle through the cooperation between the connecting member and the mounting hole 131; the setting of the first spacing D1 being greater than or equal to 10 mm allows a larger connecting member such as a screw sleeve to have sufficient installation space when installed in the mounting hole 131, so as to avoid interference between the connecting member and the outer contour edge of the upper shell body 11.

[0042] like Figure 1 , Figure 3 and Fig. 9 As shown, a navigation controller of an embodiment of the present application, wherein a working element 22 is arranged on the integrated circuit board 20, the working element 22 can realize the main functions of the integrated circuit board 20, and a first shielding portion 112 is provided inside the upper shell body 11, the first shielding portion 112 is arranged to surround the connector 21, and the connector 21 and the working element 22 are isolated by the first shielding portion 112.

[0043] In a specific implementation, the first shielding portion 112 can isolate the connector 21 from the working element 22, that is, the first shielding portion 112 and the remaining side walls of the upper shell body 11 can surround the working element 22 as a whole, thereby preventing the electromagnetic radiation of the working element 22 from leaking from the interface of the connector 21 during operation, thereby achieving an electromagnetic shielding effect and preventing other components in the vehicle from being electromagnetically interfered with by the navigation controller.

[0044] Specifically, a first connecting port 141 is opened on the first side wall 14, and a second connecting port 33 is opened on the side wall of the lower shell 30. The first connecting port 141 and the second connecting port 33 are arranged relative to each other and can be spliced ​​to form an integral connecting port for the connector 21 to pass through the integral connecting port. The setting of the first shielding portion 112 can prevent the electromagnetic radiation of the working element 22 from leaking from the first connecting port.

[0045] Specifically, the surfaces of the integrated circuit board 20 that are in contact with the side walls of the upper shell body 11 and the first shielding portion 112 are covered with copper, which can further enhance the shielding of the electromagnetic interference of the working element 22 .

[0046] like Figure 3 and Fig. 9 As shown, a navigation controller of an embodiment of the present application, wherein the first shielding portion 112 is arranged in a plate-like structure, the first shielding portion 112 is arranged to protrude from the surface of the upper shell body 11 facing the integrated circuit board 20 along the third direction Z, and there is a second spacing D2 between the first shielding portion 112 of the plate-like structure and the connector 21, and the second spacing D2 has the following range: D2 ≥ 2mm.

[0047] In a specific implementation, the first shielding portion 112 of the plate-like structure is light in weight and has a large coverage area. When the first shielding portion 112 is protruded toward the surface of the integrated circuit board 20, it can form an isolation effect on the connector 21 and the working element 22, meeting the requirements of lightweight navigation controller and shielding internal electromagnetic interference. The second spacing D2 is greater than or equal to 2 mm, which can avoid contact and interference between the first shielding portion 112 and the connector 21.

[0048] like Figure 3 and Figure 8 As shown, the navigation controller of the embodiment of the present application, wherein the upper shell body 11 also has a plurality of heat dissipation parts 113 and a plurality of heat-conducting parts 118 arranged at intervals, the plurality of heat dissipation parts 113 are all protruded from the surface of the upper shell body 11 away from the integrated circuit board 20, the plurality of heat-conducting parts 118 are arranged opposite to the plurality of working elements 22, and the heat-conducting parts 118 are protruded from the surface of the upper shell body 11 facing the integrated circuit board 20 and are in contact with the corresponding working elements 22.

[0049] In a specific implementation, the heat-conducting portion 118 in contact with the working element 22 can guide the heat generated by the working element 22 to the upper shell body 11. The heat can reach the multiple heat dissipation portions 113 through the upper shell body 11. Since the multiple heat dissipation portions 113 are spaced apart and protrude outward, the contact area between the upper shell body 11 and the external environment is expanded, thereby guiding the heat into the external environment and achieving effective heat dissipation.

[0050] Specifically, the heat-conducting portion 118 is in contact with the corresponding working element 22 via a heat-conducting adhesive. The heat-conducting adhesive can improve the heat dissipation effect of the working element 22 and can effectively conduct the heat of the working element 22 to the heat-conducting portion 118 .

[0051] like Figure 4As shown, in the navigation controller of the embodiment of the present application, multiple heat dissipation parts 113 are extended in the same direction, and a single heat dissipation part 113 has two heat dissipation surfaces 114 arranged opposite to each other, and an angle A is formed between the heat dissipation surfaces 114 and the surface of the upper shell body 11, and the angle A has the following range: A>90°.

[0052] In a specific implementation, the angle A between the heat dissipation surface 114 and the surface of the upper shell body 11 is set to be greater than 90°, so that the heat in the heat dissipation part 113 can be radiated through the heat dissipation surface 114 in a direction away from the upper shell body 11, thereby improving the heat dissipation effect of the heat dissipation part 113; and the setting of the angle A greater than 90° gradually increases the distance between the relatively arranged heat dissipation surfaces 114 of two adjacent heat dissipation parts 113, thereby avoiding the situation where heat is retained between the two adjacent heat dissipation parts 113, and also improving the heat dissipation effect of the heat dissipation part 113.

[0053] like Figure 5 As shown, a navigation controller of an embodiment of the present application, wherein an installation portion 115 having a stepped structure is arranged inside the upper shell body 11, and is arranged on the inner surface of the side wall of the upper shell body 11, and the installation portion 115 has a installation surface 116 arranged toward the lower shell body 30, and the integrated circuit board 20 is installed on the installation surface 116.

[0054] In specific implementation, the mounting portion 115 with a stepped structure and the mounting surface 116 disposed toward the lower shell 30 provide a stable mounting base for the integrated circuit board 20, so that the top of the integrated circuit board 20 can be disposed on the mounting surface 116, and the edge can be clamped on the inner surface of the side wall of the upper shell body 11.

[0055] Specifically, the mounting portion 115 is disposed around the inner surfaces of the side walls of the upper shell body 11 except the first side wall 14 , and can form a closed cavity together with the first shielding portion 112 , thereby improving the shielding effect of electromagnetic interference on the working element 22 .

[0056] like Figure 3 and Figure 7 As shown, in the navigation controller of the embodiment of the present application, the mounting hole 131 of one of the connecting parts 13 is a positioning hole, and the diameter of the positioning hole is smaller than the diameter of the mounting holes 131 of the other connecting parts 13 .

[0057] In specific implementation, the diameter of the positioning hole is smaller than the diameter of the mounting hole 131 of the other connecting part 13. During the installation process, the positioning hole and the connecting piece can be assembled first to determine the basic position of the navigation controller, and then the connecting piece can be connected to the other mounting holes 131. The diameter of the other mounting holes 131 is larger, which can meet a certain installation error, thereby enhancing the overall installation adaptability of the navigation controller.

[0058] like Figures 11 to 15 As shown, in the navigation controller of the embodiment of the present application, a second shielding portion 31 is arranged inside the lower shell 30, and the second shielding portion 31 is arranged opposite to the first shielding portion 112. The second shielding portion 31 is a plate-like structure and protrudes from the surface of the lower shell 30 facing the integrated circuit board 20.

[0059] In specific implementation, the second shielding part 31 of the plate-like structure is light in weight and has a large coverage area. When the second shielding part 31 is protruded toward the surface of the integrated circuit board 20, it can work together with the first shielding part 112 to completely isolate the connector 21 from the working element 22, thereby enhancing the isolation effect and meeting the requirements of lightweight navigation controller and shielding internal electromagnetic interference.

[0060] like Figures 11 to 15 As shown, the navigation controller of the embodiment of the present application has a plurality of first fixing holes 117 inside the upper shell body 11, and a plurality of second fixing holes 32 inside the lower shell body 30, and the plurality of first fixing holes 117 are arranged relative to the plurality of second fixing holes 32; the navigation controller also includes a plurality of fixing members 40, and the plurality of first fixing holes 117 and the plurality of second fixing holes 32 are connected via the plurality of fixing members 40.

[0061] In specific implementation, the fixing members 40 are respectively inserted into the corresponding first fixing holes 117 and second fixing holes 32, so that the upper shell 10 and the lower shell 30 can be fixedly connected, thereby fixing the integrated circuit board 20 between the two to realize the overall assembly of the navigation controller.

[0062] Specifically, the integrated circuit board 20 has a plurality of fixing through holes 23, and the plurality of fixing through holes 23 are arranged relative to the plurality of first fixing holes 117 and the plurality of second fixing holes 32. The fixing parts 40 can be sequentially inserted into the corresponding first fixing holes 117, the fixing through holes 23 and the second fixing holes 32, thereby further improving the installation stability of the integrated circuit board 20.

[0063] Specifically, the upper shell body 11 has a first positioning portion 119 inside, and the lower shell body 30 has a second positioning portion 34 inside. The first positioning portion 119 and the second positioning portion 34 are arranged relative to each other, and the first positioning portion 119 is a columnar structure, and the second positioning portion 34 is a hole structure. When assembling the navigation controller, it is necessary to insert the first positioning portion 119 into the second positioning portion 34 to achieve positioning between the upper shell 10 and the lower shell 30, and then fix the upper shell 10 and the lower shell 30.
