Description

Combined navigation device

Technical Field

The application relates to the field of electronic equipment, in particular to a combined navigation device.

Background

Integrated navigation generally refers to a module that provides accurate positioning with a multi-sensor fusion scheme of Global Navigation Satellite System (GNSS) and Inertial Measurement Unit (IMU). In recent years, with rapid development of positioning service, users have put forward higher and higher requirements on positioning accuracy of vehicle-mounted terminals, and original navigation levels are gradually replaced to lane levels. Especially in urban canyon environments (high building, overhead), the user cannot receive the GNSS signals or the GNSS signals are disturbed, resulting in no positioning result or poor positioning accuracy of the GNSS. This is an inherent disadvantage of "active positioning" and cannot be algorithmically overcome. Aiming at the problem, more and more attention is paid to a multi-sensor fusion scheme such as GNSS+IMU, because the IMU of passive positioning can exactly compensate a short plate of satellite positioning.

The integrated navigation device is provided with a connector serving as an external interface, the connector is inserted into a mounting port on the shell, and one end of the connector, which is positioned inside the shell, is electrically connected with the circuit board. In the integrated navigation device of the related art, because an assembly gap exists between the mounting port and the connector, the inner end of the connector easily shakes, so that the mounting stability of the connector is poor, and the electrical connection between the connector and the circuit board is poor, thereby influencing the functions of the whole machine.

FIG. 1 is a schematic diagram of an integrated navigation device 010 according to an embodiment of the present application; fig. 2 is an exploded view of integrated navigation device 010 in an embodiment of the present application. Referring to fig. 1 and 2, the integrated navigation device 010 provided in the present embodiment includes a housing 100, a circuit board 300, and a connector 200. The housing 100 forms a receiving chamber, the housing 100 is provided with a mounting opening 101, the connector 200 has a first end and a second end opposite to each other in a first direction (arrow ab direction in the drawing), and the connector 200 is inserted into the mounting opening 101 such that the first end is positioned in the receiving chamber and the second end is positioned outside the receiving chamber. The circuit board 300 is disposed in the accommodating chamber, and has electronic devices such as various sensors and chips mounted thereon. The connector 200 is electrically connected to the circuit board 300.

In an alternative embodiment, the housing 100 includes an upper case 110 and a lower case 120, the upper case 110 and the lower case 120 are fastened in a second direction (arrow ef direction in the figure) to form a receiving cavity of the housing 100, the upper case 110 includes a top plate 111 and an upper side plate 112 standing on an edge of the top plate 111, the lower case 120 includes a bottom plate 121 and a lower side plate 122 standing on an edge of the bottom plate 121, an upper notch is provided on an edge of the upper side plate 112, a lower notch is provided on an edge of the lower side plate 122, and the upper notch and the lower notch jointly form the mounting port 101.

Fig. 3 is a schematic diagram of a connector 200 according to an embodiment of the present application. Referring to fig. 1 to 3, a limiting structure 130 is disposed on the inner side of the housing 100, and the limiting structure 130 is used for limiting displacement of the first end of the connector 200 in a second direction, wherein the second direction is perpendicular to the first direction. In this embodiment, the limiting structure 130 is disposed inside the upper shell 110, and by disposing the limiting structure 130, when the first end (i.e. the inner end) of the connector 200 swings towards the direction close to the upper shell 110, the limiting structure 130 can abut against the connector 200 to block the first end from continuing to swing towards the upper shell 110. Therefore, the limit structure 130 can improve the stability of the connector 200 in the second direction to some extent. Further, the limiting structure 130 in the present embodiment can also limit the displacement of the first end of the connector 200 in the third direction (the arrow cd direction in the figure), so as to improve the stability of the connector 200 in the third direction, which is perpendicular to the first direction and the second direction. Further, the limiting structure 130 in the present embodiment can also limit the displacement of the connector 200 in the first direction, and in particular can block the connector 200 from being further inserted into the accommodating cavity.

As shown in fig. 3, the connector 200 is substantially rectangular and the connector 200 includes a housing body 210 and a plurality of pins 220 disposed on the housing body 210. The housing body 210 forms a cavity at the second end of the connector 200 with an opening for a plug-in fit with an external device. One end of the pin 220 is located within the housing body 210 and the other end extends from the second end of the connector 200 for electrical connection with the circuit board 300.

The side of the connector 200 facing the top plate 111 is provided with the first boss 211, and the first boss 211 is used for abutting against the limiting structure 130 to prevent the connector 200 from excessively moving into the housing 100 along the first direction, so that the shaking of the connector 200 in the first direction can be reduced to a certain extent, and the stability of the connector 200 in the first direction is improved. In this embodiment, two first bosses 211 are disposed on the connector 200, and the two first bosses 211 are spaced apart in the third direction.

Further, the first end of the connector 200 is provided with a second boss 212 along the first direction, and the second boss 212 is used for abutting against the limiting structure 130 to limit the position of the connector 200 in the second direction and the third direction, so as to improve the stability of the connector 200 in the second direction and the third direction. In the present embodiment, the connector 200 is provided with two second bosses 212, and the two second bosses 212 are disposed at intervals in the third direction. The two second bosses 212 are respectively used for abutting the limiting structure 130 in two opposite directions (both parallel to the third direction), so as to limit the position of the connector 200 in the third direction.

FIG. 4 is a schematic view of the inside of the upper shell 110 in one embodiment of the present application; FIG. 5 is a schematic illustration of the upper shell 110 mated with the connector 200 in one embodiment of the present application; fig. 6 is an enlarged view of a portion VI in fig. 4. As shown in fig. 4 to 6, in the present embodiment, the limiting structure 130 is protruding on the inner surface of the top plate 111. The limiting structure 130 specifically includes a first limiting portion 131, two second limiting portions 132, and two third limiting portions 133.

The first limiting portion 131 is protruding on the inner surface of the top plate 111, and the first limiting portion 131 is used for blocking the first end of the connector 200 from being close to the top plate 111. In the assembled state, the first limiting portion 131 may contact the surface of the connector 200, or may maintain a certain gap (the gap may be smaller than the gap between the upper notch edge of the upper side plate 112 and the surface of the connector 200). When the first end of the connector 200 swings or has a tendency to swing toward the top plate 111, the first limiting portion 131 may block the connector 200, thereby performing a limiting effect. Thus, the contact pin 220 and the circuit board 300 are prevented from losing connection relation or loose connection due to the movement of the first end of the connector 200 toward the upper housing 110, thereby ensuring the stability of electrical connection.

In the present embodiment, the first limiting portion 131 is strip-shaped and extends along the third direction. The first limiting portion 131 corresponds to the second boss 212 on the connector 200 in position in the second direction, and thus can abut against the second boss 212 when the first end of the connector 200 approaches the upper case 110, thereby limiting the connector 200.

Two second limiting portions 132 are disposed on the inner surface of the top plate 111, one end of each second limiting portion 132 is connected to the top plate 111, and the other end extends toward the lower shell 120. The two second limiting portions 132 are spaced apart in the third direction, and the two second limiting portions 132 are connected to both ends of the first limiting portion 131 in the third direction. The first end of the connector 200 is located between the two second limiting portions 132.

By providing two second limiting portions 132, the first end of the connector 200 can be blocked from shaking in the third direction, thereby improving the stability of the connector 200 in the third direction. In particular, in the present embodiment, the two second limiting portions 132 are respectively opposite to the two second bosses 212 of the connector 200 in the third direction, so that when the first end of the connector 200 shakes in the third direction, the second limiting portions 132 can abut against the second bosses 212, thereby limiting the connector 200.

Further, two third limiting portions 133 are spaced apart in the third direction, and the third limiting portions 133 connect the second limiting portion 132, the upper side plate 112, and the top plate 111. By providing the third limiting portion 133, the first end of the connector 200 can be further wrapped, and stability of the connector 200 is improved. The third limiting portion 133 can also block the foreign matters entering from the gap of the mounting opening 101 to a certain extent, so as to prevent the foreign matters from further entering into the mounting cavity of the housing 100 and affecting the operation of the circuit board 300 and the electrical components thereon.

FIG. 7 is a cross-sectional view of integrated navigation device 010 in an embodiment of the present application; fig. 8 is an enlarged view of part VIII in fig. 7. As shown in fig. 7 and 8, in the present embodiment, the first boss 211 is located between the first limiting portion 131 and the upper side plate 112. Further, the first boss 211 may abut against the first limiting portion 131 in the first direction or reserve a gap with the first limiting portion 131 in the first direction. By so doing, when the connector 200 is displaced in the first direction, the first stopper 131 can block the first boss 211, avoiding excessive insertion of the connector 200; the upper side plate 112 can block the first boss 211 from being pulled out of the mounting port 101. By providing the first boss 211 between the first stopper 131 and the upper side plate 112, stability of the connector 200 in the first direction can be improved.

Referring to fig. 2, 4 and 5, further, a heat generating element 310 is disposed on the circuit board 300, and the heat generating element 310 may be a chip. The inner side of the upper shell 110 is provided with a heat conducting boss 114, and the heat conducting boss 114 is abutted against a heating element 310 on the circuit board 300. Specifically, the thermally conductive boss 114 may be a metal block, such as a copper block, having a relatively high thermal conductivity. A heat conducting pad or a heat conducting silicone grease can be arranged between the heat conducting boss 114 and the heating element 310 to reduce an air gap between the heat conducting boss 114 and the heating element 310, so that the heat transfer efficiency is improved, the heat dissipation efficiency of the heating element 310 is improved, and overheating of the heating element 310 is avoided.

Further, the outer surface of the upper case 110 is provided with the heat radiating fins 113, thereby improving heat radiating performance by increasing a heat exchanging area.

In the present embodiment, the circuit board 300 may be fixed in the lower case 120 by a fastener such as a screw. In the present embodiment, a harness clip 123 is provided in the lower case 120 of the housing 100, and can be used to fix a harness.

Further, a shielding plate 115 is further disposed on the outer side of the upper side plate 112, and the shielding plate 115 covers the first port 400, the second port 500 and the connector 200 to protect the ports and the connector 200.

Further, the outer side of the lower case 120 is provided with a plurality of connection parts 124, and the connection parts 124 are used to mount and fix the integrated navigation device 010 to an external target member.
