Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning technology, and in particular to a highly stable positioning module structure. Background Technology
[0002] Positioning technology can provide users with accurate location information anytime, anywhere. It processes the signal received by the receiver, calculates the location information after error processing, and then transmits the location information to the connected device. The connected device performs certain calculations and transformations on the information (such as map projection transformation, coordinate system transformation, etc.) before transmitting it to the mobile terminal. When applied to electric vehicles, positioning technology can be used as an anti-theft alarm and tracking device for electric vehicles and motorcycles.
[0003] Currently, there are two main ways to set up positioning modules in the industry. One is to integrate them into the BMS system of the electric vehicle battery. This method is technically more difficult, and because it is integrated and packaged with the battery, the positioning module can only be scrapped along with the scrapped battery, resulting in a waste of resources.
[0004] Another approach, often using an external structure, consists of a separate housing and an internally sealed positioning motherboard. It connects to the vehicle's infotainment system via terminal blocks. This type of positioning module offers high flexibility, making replacement or relocation extremely convenient. However, because the terminal block and motherboard need to be pre-connected as a single unit before being sent to the next process (installation in the housing), the soldered wires connecting the terminal block and motherboard often detach or crack during transport to the next assembly station on the production line. This disrupts signal transmission, necessitating rework. This not only impacts production efficiency but also affects the final product yield. Therefore, it is necessary to design a new positioning module structure to avoid these problems. Utility Model Content

Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0029] The preferred embodiment of this utility model features a highly stable positioning module structure, such as... Figure 1-7As shown, the structure includes a housing 10 with an opening at one end, specifically, the housing 10 is a barrel-shaped cuboid structure; further, the structure of this solution also includes a cover 20 that seals the opening of the housing 10, the cover 20 having an inner cavity of a certain depth and being rectangular in shape, and being able to align with the opening end of the housing 10 and form a sealed cavity structure with the housing 10; further, the structure of this solution also includes a positioning main board 30 disposed in the inner cavity of the housing 10, and a wiring terminal 40 disposed on the cover 20; the wiring terminal 40 includes a terminal base 41 and connecting pins 42 extending through it, wherein the terminal base 41 is a cuboid structure and is arranged in the left-right direction, and the connecting pins 42 are provided in multiple positions along the left-right direction. The positioning main board 30 is provided with a terminal block 31 for connecting to the connection pins; the outer peripheral side wall of the terminal block 41 is provided with an annular rib 50, and the inner side wall of the cover 20 is provided with positioning holes 21 and countersunk holes 22 that are adapted to the terminal block 41 and the annular rib 50, respectively. The left and right ends of the positioning main board 30 are provided with a first extension 32 that extends into the countersunk hole 22 and is detachably connected to its inner wall; the structure of this solution, through the cooperation of the first extension 32 and the countersunk hole 22, enables the first extension 32 and the countersunk hole 22 to be detachably connected, which can realize the initial fixed connection between the terminal block 41 and the positioning main board 30, greatly facilitating the assembly work and effectively reducing the defect rate of the product during transportation and assembly on the production line.
[0030] In this embodiment, when assembled in place, the first extension 32 presses the annular rib 50 against the front side wall of the countersunk hole 22 to prevent the terminal block 41 from moving and to ensure the stability of the installation.
[0031] In this embodiment, the annular rib 50 is flush with and coplanar with the rear side wall of the terminal block 41 and together form an annular abutment position. An annular rubber pad 60 is coaxially provided on the abutment position. The outer peripheral side wall of the annular rubber pad 60 fits tightly against the inner peripheral side wall of the countersunk hole 22 to seal the countersunk hole 22 and the positioning hole 21.
[0032] In this embodiment, each of the two first extensions 32 has an arc-shaped protrusion 321 at one end facing away from each other. The inner wall of the countersunk hole 22 is provided with a positioning groove 221 that matches the arc-shaped protrusion 321. When the positioning main board 30 is inserted into the cover 20 and the first extension 32 extends into the countersunk hole 22, the arc-shaped protrusion is engaged in the positioning groove 221, thereby realizing the initial connection between the positioning main board 30 and the cover 20. This allows the positioning main board 30, the terminal block 41, and the cover 20 to form an integral module and maintain a certain connection stability, which facilitates the subsequent transportation and transmission of the integral module.
[0033] In this embodiment, a guide slope 322 is provided on one end face of the two first extensions 32 that are opposite to each other. The guide slope 322 is located on the side of the arc protrusion 321 that is close to the terminal block 41. The distance between the near ends of the two guide slopes 322 is less than the left and right width of the countersunk hole 22, so that the first extension 32 can be inserted into the countersunk hole 22.
[0034] In this embodiment, an annular step 61 is coaxially recessed on one end face of the annular rubber gasket 60 facing the first extension 32. An annular metal gasket 70 is coaxially provided on the annular step 61. When assembled, the end of the guide slope 322 facing the terminal seat 41 is aligned with the outer peripheral sidewall of the annular metal gasket 70. Through the cooperation of the annular step 61, the annular metal gasket 70 and the first extension 32, not only can the axial end face of the annular rubber gasket 60 be pressed against the abutment position to ensure the seal of the bottom surface of the countersunk hole 22, but also the radial deformation of the annular rubber gasket 60 can be used to press its outer peripheral sidewall against the inner peripheral sidewall of the countersunk hole 22 and align for sealing. The annular metal gasket 70 is generally made of stainless steel with high deformation resistance to ensure that the pressing force from the first extension 32 can be more evenly distributed on the annular rubber gasket 60, ensuring better sealing of the entire countersunk hole 22.
[0035] In this embodiment, the inner wall of the cover 20 is provided with an annular cofferdam 23 surrounding the countersunk hole 22. The inner wall of the annular cofferdam 23 is coaxially aligned with the inner wall of the countersunk hole 22 to further deepen the depth of the countersunk hole 22. The positioning groove 221 is located on the inner wall of the annular cofferdam 23 (or it can be set on the original inner wall of the countersunk hole 22). By deepening the depth of the countersunk hole 22 through the annular cofferdam 23, it is convenient to connect and fix the first extension 32. At the same time, it can avoid the disadvantage that the cover 20 must be thicker to provide a forming position for the countersunk hole 22.
[0036] In this embodiment, a second extension 33 is provided on the positioning motherboard 30 corresponding to the first extension 32. The first extension 32 is located at the end of the second extension 33, and both are integrally connected to the positioning motherboard 30. That is, the first extension 32 and the second extension 33 are both cut and formed by the positioning motherboard 30. When assembled, the opposite ends of the two second extensions 33 are pressed against the inner wall of the cover 20, and the end of the second extension 33 facing the terminal block 41 is pressed against the annular weir 23. Furthermore, in order to enhance the stability of the initial assembly of the positioning motherboard 30, two first positioning ribs 80 are provided on the inner side wall of the cover 20 to position the upper and lower surfaces of the second extension 33. This also facilitates the insertion process of the positioning motherboard 30 during assembly with the cover 20, and prevents the front end of the motherboard from tilting up and down after the initial assembly. Furthermore, second positioning ribs 101 are also provided on the left and right side walls of the inner cavity of the outer shell to position and guide the rear end of the positioning motherboard 30.
[0037] In this embodiment, the end face of the cover 20 away from the outer shell 10 is provided with an annular rib wall 90 surrounding the positioning hole 21. When assembled in place, the inner sidewall of the annular rib wall 90 fits against the outer sidewall of the terminal block 41. Furthermore, the diameter of the terminal block 41 gradually decreases along the direction away from the cover 20 and forms a structure with an isosceles trapezoidal cross-section, so as to play a role in assisting assembly positioning. At the same time, it can also fix the end of the terminal block 41 that extends out of the cover 20 to ensure the stability of the terminal block 41.
[0038] In this embodiment, the cover 20 is detachably connected to the end face of the opening end of the outer shell 10 by screws 201. There is a sealing ring 100 between the cover 20 and the opening end face of the outer shell 10. The cover 20 is provided with a positioning groove 110 for positioning the sealing ring 100. The outer shell 10 is provided with a positioning rib 120 that matches the positioning groove 110. After assembly, the positioning rib 120 presses the sealing ring 100 against the positioning groove 110 and achieves the sealing between the cover 20 and the outer shell 10.
[0039] Furthermore, the lower part of the cover 20 opposite to the outer casing 10 has a horizontal extension arm 120, and the end of the extension arm 120 has a longitudinal through slot 121 for screwing in screws to fix the entire structure to the frame.
[0040] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
