All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the utility model, are within the scope of the utility model.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

The ultra-wideband module of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the vehicle-mounted electronic module of the present invention includes a housing 1, an insert, and a rear cover 2. An opening is formed at the rear end of the shell 1, a plurality of pin holes 3 and a connector part 8 are formed at the front end of the shell 1, and clamping parts are arranged at two sides in the shell 1; the embedded part comprises a PCB (printed circuit board) 4 and a plurality of contact pins 5 which are in one-to-one correspondence with the contact pin holes 3, one ends of the contact pins 5 are fixed at the front end of the PCB 4, the other ends of the contact pins 5 penetrate through the contact pin holes 3 to be arranged in the interface part 8, and two sides of the PCB 4 are fixed at two clamping parts; the rear cover 2 is engaged with an opening at the rear end of the housing 1. In one embodiment, the in-vehicle electronics module may be an ultra-wideband antenna module.

The specific assembling process of the vehicle-mounted electronic module provided by the utility model comprises the following steps: firstly, connecting the contact pin 5 and the PCB 4 together, wherein the connecting mode is divided into two modes, one mode is the crimping mode, and the other mode is to weld the contact pin 5 on the PCB 4 in a reflow soldering mode; then inserting the PCB 4 from the opening at the rear end of the shell 1, so that the contact pin 5 is inserted into the contact pin hole 3 and the two sides of the PCB 4 are fixed by the clamping parts; and finally, buckling the rear cover 2 at the opening at the rear end of the shell 1, thereby completing the assembly. The housing 1 of the vehicle-mounted electronic module is a single plastic part, so that the purchase cost of the housing 1 is greatly reduced, the development period is obviously shortened, and more suppliers can be selected.

Further, as shown in fig. 2 to 3, the detent portions are formed as two elongated grooves 6 parallel to each other in a direction from the front end of the housing 1 to the rear end of the housing 1.

The clamping part of the vehicle-mounted electronic module is arranged into the long groove 6, so that the PCB 4 only needs to be pushed into the front end from the rear end of the long groove 6 in the process of inserting the PCB 4 into the shell 1. The position of the elongated slot 6 needs to be designed according to the sizes of the PCB 4 and the pin 5 to ensure that the pin 5 can be just inserted into the pin hole 3 after the PCB 4 is pushed in, so the elongated slot 6 not only has a positioning function, but also has a guiding function. The structure enables the assembly process to be simpler, more convenient and faster, and effectively improves the assembly efficiency.

Further, as shown in fig. 1-2, the rear end of the long groove 6 is formed in an arc shape. The arc-shaped structure can play a role in guiding when the PCB 4 is inserted at the beginning, and the condition that the PCB 4 is misaligned is greatly reduced.

Further, as shown in fig. 2-3, a position limiting portion 7 is formed at a position of the housing 1 corresponding to the front end of the PCB 4, and the front end of the PCB 4 abuts against the position limiting portion 7. The PCB 4 may be pushed in excessively, so that the PCB 4 is pushed in excessively, and the limiting portion 7 may limit the pushing distance to avoid the pushing in excessively.

The structure and position of the stopper portion 7 include various cases, for example: the limiting part 7 is formed into two convex edges which are respectively positioned at the front end inside the shell 1 and correspond to the position of the PCB 4; the convex edge is formed into a long strip shape perpendicular to the long groove 6; the stopper 7 is formed as two projections located at the inner front ends of the two long grooves 6.

Further, as shown in fig. 1, a groove is formed at a position of the rear cover 2 corresponding to the PCB 4, and a rear end of the PCB 4 is embedded in the groove. The PCB 4 is embedded in the groove on the rear cover 2, so that the firmness of the PCB can be further enhanced.

Further, the rear cover 2 and the case 1 are connected by laser welding. The contact part of the shell 1 and the rear cover 2 is melted by energy generated by laser, so that the shell 1 and the rear cover 2 are bonded to play a sealing role, and the interface part 8 at the front end of the shell 1 is in sealing connection with the plug-in terminal of the wiring harness, so that the whole module formed after the vehicle-mounted electronic module is connected with the wiring harness can meet the requirements of IP69 on dust prevention and water prevention.

Further, the rear cover 2 is made of a light-transmitting material, and the housing 1 is made of a light-absorbing material. The back cover 2 is made of a light-transmitting material, so that a worker can observe the inside condition of the shell 1 to judge whether the inside is damaged or not.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
