Description

Technical Field

[0001] The utility model relates to the technical field of controllers, and particularly relates to a cockpit controller. Background Art

[0002] At present, the Qualcomm 8295 chip has been tried in automotive cockpit controllers. This chip has high heat dissipation and a relatively low junction temperature, but the operating temperature range of automotive controllers is relatively large. In order to effectively utilize the computing power of the Qualcomm 8295, good heat dissipation needs to be provided for it. If liquid cooling is used to achieve the heat dissipation of the Qualcomm 8295 chip, it is difficult to be compatible with old models because the cockpit controllers of old models are generally arranged in the central control position or the co-pilot position in the cockpit, and there is no liquid cooling pipeline arranged in the cockpit of old models (mainly fuel vehicles). If the liquid cooling pipeline is rearranged, the modification is relatively large, so there is no liquid cooling environment. To solve this problem, air-cooled cockpit controllers have emerged. Such air-cooled cockpit controllers include sub-circuit boards and main circuit boards that are horizontally arranged in parallel and have comparable sizes, and also include a shielding cover in the shape of a cuboid. The shielding cover is located between the sub-circuit board and the main circuit board. The bottom and the front of the shielding cover are both open. The bottom of the shielding cover is provided with a fixing part for fixedly connecting with the top surface of the main circuit board. The sub-circuit board is simply placed on the top of the shielding cover, which will result in poor contact between the sub-circuit board and the shielding cover, and then lead to poor shielding effect of the shielding cover, and further result in poor electromagnetic compatibility of the air-cooled cockpit controller. Moreover, since the top of the shielding cover is flat, electronic components cannot be arranged in the area of the sub-circuit board that is in contact with the shielding cover, which further limits the use of the sub-circuit board.

[0003] In view of the above deficiencies, it is necessary to design a cockpit controller to overcome the above deficiencies. Summary of the Utility Model

[0036] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0039] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0040] As Figures 1 to 9 shown, the present utility model provides a cockpit controller, which includes a housing 1, a cooling fan 2, a cover plate 21, an antenna assembly 3, a shielding structure 4, a sub-board 6, and a main board 7. In this embodiment, the chip on the main board 7 is a Qualcomm 8295 chip, and the cooling fan 2 is an 8025 fan. Of course, the chip and the cooling fan 2 can also be of other models, which are not specifically limited here and can be set according to actual needs.

[0041] The housing 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 is made of die-cast aluminum alloy. The upper shell 11 and the lower shell 12 are fixed together by fasteners (such as screws), and an installation cavity is formed between the upper shell 11 and the lower shell 12. The shielding structure 4, the sub-board 6, and the main board 7 are all installed in the installation cavity. The bottom of the upper shell 11 is integrally formed with installation ears 116, so that the cost can be saved and the installation of the cockpit controller can be facilitated.

[0042] The upper shell 11 is provided with a recessed area 111 (as Figure 3 shown). The front end of the upper shell 11 is provided with a raised area 114 (as Figure 3 shown), and the front end here is the installation opening 115 (as Figure 5 where the connector 5 is opened on the upper shell 11.One end of the structure shown in the figure). The raised area 114 is connected to the sunken area 111. The raised area 114 arches away from the lower shell 12 to form a sub-circuit board accommodation cavity C below the head end (as shown in Figure 5 shown).

[0043] A plurality of U-shaped heat sinks 112 extend from the bottom wall of the sunken area 111 away from the lower shell 12. In this embodiment, there are 6 heat sinks 112. Of course, it can also be other values, which are not specifically limited here and can be set according to actual needs. The plane where the heat sinks 112 are located is perpendicular to the bottom wall of the sunken area 111. The height of the heat sinks 112 is 35 mm to 39 mm. The openings of the heat sinks 112 face away from the lower shell 12. A U-shaped air duct is formed between two adjacent heat sinks 112. The cooling fan 2 enters from the opening and is placed on the heat sinks 112, so that the distance between the bottom of the cooling fan 2 and the bottom wall of the sunken area 111 is set, and the air outlet direction of the cooling fan 2 faces the bottom wall of the sunken area 111. In this way, the air blown out by the cooling fan 2 can flow orderly under the guidance of the air duct, improving the heat dissipation effect. Preferably, a stepped surface B is provided at the corner of the vertical part and the horizontal part of the heat sink 112 (as shown in Figure 4 shown), and the cooling fan 2 is placed on the stepped surface B.

[0044] A plurality of bosses 113 protruding towards the main circuit board 7 extend from the bottom surface of the sunken area 111 (as shown in Figure 5 shown). The free ends of the bosses 113 are coated with a heat-conducting substance, such as heat-conducting glue. The heat generated by the main circuit board 7 is transferred to the upper shell 11 through the heat-conducting substance and the bosses 113, and heat dissipation is carried out with the help of the cooling fan 2. The antenna assembly 3 is arranged on the bottom wall of the sunken area 111 and protrudes away from the lower shell 12. In this embodiment, the antenna assembly 3 is installed on the bottom wall of the sunken area 111 far from the raised area 114 and is located outside the area where the heat sinks 112 are located. In this way, the signal strength and isolation degree can be improved.

[0045] A through hole (not marked) is provided at the tail end of the upper shell 11 (the tail end is the end opposite to the head end). The wire harness of the cooling fan 2 is electrically connected to the main circuit board 7 through the through hole. The temperature sensor in the chip on the main circuit board 7 monitors the temperature of the chip and sends the temperature signal to the micro-control unit on the main circuit board 7. The micro-control unit adjusts the rotation speed of the cooling fan 2 according to the temperature signal. In this way, the service life of the cooling fan 2 can be improved, and at the same time, energy consumption can be reduced.

[0046] The sub-circuit board 6 is arranged parallel to the main circuit board 7. The length of the sub-circuit board 6 is less than the length of the main circuit board 7 (the length direction is as shown in Figure 4). The projection of the sub-circuit board 6 on the plane where the main circuit board 7 is located falls on the main circuit board 7. The copper-clad areas A continuously arranged on the sub-circuit board 6 and the main circuit board 7 are connected to the ribs on the shell 1 to achieve grounding. The sub-circuit board 6 is placed in the sub-circuit board accommodating cavity C and is located between the main circuit board 7 and the upper shell 11. Such a design can not only use the sub-circuit board to achieve functional expansion, but also make the heat sink 112 in the recessed area 111 closer to the chip on the main circuit board 7, thereby improving the heat dissipation efficiency of the chip and further ensuring that the chip can give full play to its computing power. In this embodiment, when wiring the main circuit board 7, care should be taken to ensure that the chip is away from other heat sources, such as power amplifier components and other heat-sensitive devices are away from the chip. Combined with a large-sized (height of 35mm to 39mm) heat sink 112, the heat dissipation efficiency can be improved, and the maximum computing power of the chip can be exerted without frequency reduction.

[0047] The shielding structure 4 is made of pre-galvanized steel sheet, and is in a Z-shape as a whole, and is located between the main circuit board 7 and the sub-circuit board 6. The shielding structure 4 includes a main body 41 in a straight plate shape, two first fixing parts 42, a bending plate 43 located between the two first fixing parts 42, and two second fixing parts 44. The first fixing part 42 is in a Z-shape. The bending plate 43 is in an L-shape. The first fixing part 42 and the bending plate 43 are both bent and extended from the top of the main body 41 to the outside (the outside is the side of the main body 41 facing away from the center of the main circuit board 7), and the inner sides of the two first fixing parts 42 are respectively connected to the two opposite sides of the bottom wall of the bending plate 43. In this way, on the one hand, the strength of the first fixing part 42 can be improved, and on the other hand, the gap between the first fixing part 42 and the bending plate 43 can be reduced, thereby improving the shielding effect of the shielding structure. The second fixing part 44 is bent and extended from the bottom end of the main body 41 to the inside (the inside is the side of the main body 41 facing the center of the main circuit board 7). The first fixing portion 42 is fixedly connected to the copper-clad area A on the sub-circuit board 6. A clearance space D (such as Figure 8 As shown in the figure, the clearance space D is used to make room for the electronic components on the bottom surface of the sub-circuit board 6, thereby improving the utilization rate of the sub-circuit board 6. In the thickness direction of the sub-circuit board 6, there is a gap between the top of the bending plate 43 and the sub-circuit board 6. In this embodiment, the gap is 0.18mm to 0.22mm. The bottom end of the main body 41 is connected to the soldering area on the main circuit board 7. The second fixing portion 44 is fixedly connected to the copper-clad area A on the main circuit board 7 through a fastener.

[0048] The cockpit controller provided by the present utility model includes a housing 1, a shielding structure 4, a sub-circuit board 6, and a main circuit board 7, all of which are disposed inside the housing 1; the sub-circuit board 6 and the main circuit board 7 are arranged opposite to each other; the shielding structure 4 is integrally Z-shaped and is located between the main circuit board 7 and the sub-circuit board 6. The shielding structure 4 includes a main body portion 41, two first fixing portions 42, a bending plate 43 located between the two first fixing portions 42, and two second fixing portions 44; wherein, the Z-shaped first fixing portion 42 and the L-shaped bending plate 43 are both bent and extended outward from the top end of the main body portion 41, and the second fixing portion 44 is bent and extended inward from the bottom end of the main body portion 41; wherein, the first fixing portion 42 is fixedly connected to the copper-clad area A on the sub-circuit board 6, and a clearance space is formed between the inner bottom wall of the bending plate 43 and the bottom surface of the sub-circuit board 6, thereby improving the utilization rate of the sub-circuit board. In the thickness direction of the sub-circuit board 6, there is a gap between the top end of the bending plate 43 and the sub-circuit board 6; the bottom end of the main body portion 41 is connected to the soldering area on the main circuit board 7, and the second fixing portion 44 is fixedly connected to the copper-clad area A on the main circuit board 7. In this way, the shielding structure 4 can achieve stable connection with both the sub-circuit board 6 and the main circuit board 7, thereby improving the electromagnetic compatibility of the entire cockpit controller. Moreover, the design of the sub-circuit board 6 and the main circuit board 7 makes it possible to expand more functional interfaces.

[0049] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.

And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
