[0002] In existing technologies, automotive angle sensors are typically integrated or highly integrated structures, combining core functional components such as sensing circuits, electrical pins, and structural support components into a single complex part. This requires high machining accuracy and process precision, and machining deviations are prone to occur during prototype processing, resulting in inconsistencies between the prototype and the actual model, large assembly dimensional deviations, and failure to meet installation accuracy requirements, thus preventing direct installation testing. Furthermore, existing automotive angle sensors require the use of soft molds for processing, which is costly and has a long production cycle. Summary of the Invention

[0007] Furthermore, the PIN needle assembly includes multiple PIN needles, each PIN needle having a needle body in the middle, a needle tip at one end, and a limiting platform at the other end; the diameter of the needle body is adapted to the placement hole, and the diameter of the limiting platform is larger than the needle body and abuts against the surface of the needle block fixing post.

[0008] Furthermore, the automotive angle sensor assembly structure also includes a PIN pin fixing pin, which has multiple fixing holes for the pin body to pass through. The outer wall of the support arm has a fixing groove, and the PIN pin fixing pin is disposed in the mounting hole and engages with the fixing groove.

[0009] Furthermore, a fixing rib is provided at the connection between the support arm and the mounting section, and the fixing rib abuts against the inner wall of the docking hollow column.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this application to help readers better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0019] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0020] Reference Figure 1 and Figure 4 This application proposes an automotive angle sensor assembly structure, including a top cover 1, a PCBA 2, a PCBA bracket 3, a pin block fixing post 4, and a PIN pin assembly 5. The PCBA bracket 3 has a first side and a second side facing away from each other. The pin block fixing post 4 is detachably connected to the first side of the PCBA bracket 3. The PIN pin assembly 5 is partially installed inside the pin block fixing post 4, and a portion of the PIN pin assembly 5 passes through the PCBA bracket 3 and is located on the second side of the PCBA bracket 3. The PCBA 2 is disposed on the second side of the PCBA bracket 3 and is electrically connected to the PIN pin assembly 5. The top cover 1 is connected to the PCBA bracket 3 and covers the PCBA 2 and the PIN pin assembly 5.

[0021] The automotive angle sensor assembly structure provided in this embodiment adopts a split modular design, in which all components can be independently prefabricated and assembled into a whole through mechanical assembly.

[0022] See Figure 1 , Figure 5 and Figure 10In a specific assembly scenario, the PIN pin assembly 5 is first pre-installed into the pin block fixing post 4 to form a pin group unit. Then, the pin group unit is inserted into the PCBA bracket 3 from the first side (below), so that the pin tip 53 and part of the pin body 52 of the PIN pin assembly 5 extend through the PCBA bracket 3 to the second side (above). Subsequently, the PCBA2 is installed on the second side of the PCBA bracket 3, so that the PIN pin assembly 5 and the conductive area of ​​the PCBA2 form an electrical connection. Finally, the top cover 1 is fastened onto the PCBA bracket 3 to complete the overall assembly.

[0023] All PIN pins in this application are assembled independently and do not require secondary injection molding as inserts. Therefore, only a small number of independent injection molds need to be developed, eliminating the original PIN pin injection molds and two injection molding processes.

[0024] The automotive angle sensor assembly structure in this embodiment adopts a modular design with a top cover, PCBA, PCBA bracket, pin block fixing post, and PIN pin assembly. This transforms the traditional integrated injection molding structure into a purely mechanical assembly structure, eliminating two insert injection molding processes. Only a small number of independent injection molds need to be developed, significantly reducing mold development costs and greatly shortening the production cycle. Furthermore, each damaged component can be disassembled and replaced individually without scrapping the entire sensor, greatly reducing the production scrap rate. The PIN pin assembly is partially installed inside the pin block fixing post, so that burrs and warping generated during PIN pin punching are completely covered in the internal structure. This effectively prevents mold punctures or molding defects, reduces electrical faults such as short circuits and poor contact, and improves product lifespan.

[0025] In an optional embodiment of this application, the PCBA support 3 is provided with a mounting groove 31 adapted to the PCBA 2, and the mounting groove 31 is provided with a mounting hole 32 for accommodating the PIN pin assembly 5 and the pin block fixing post 4; the inner wall of the mounting hole 32 is provided with a fixing step 33, and the first side of the PCBA support 3 is provided with a docking hollow post 34 corresponding to the position of the mounting hole 32.

[0026] See Figure 2 and Figure 4 The PCBA bracket 3 is an integrally injection-molded insulating structural component. Its second side has a recessed mounting groove 31, the dimensions of which are adapted to the external dimensions of the PCBA2 to ensure the PCBA2's stable position after installation. A mounting hole 32, penetrating the PCBA bracket 3, is provided at a corresponding position in the mounting groove 31 to accommodate the pin block fixing post 4 and the PIN assembly 5. A raised inner wall of the mounting hole 32 forms a fixing step 33, which provides axial positioning with the pin block fixing post 4.

[0027] The first side of the PCBA bracket 3 has an integrally formed hollow post 34 corresponding to the position of the mounting hole 32. The position of the hollow post 34 corresponds to the position of the mounting hole 32 and is used to support the pin block fixing post 4 and guide the PIN pin assembly 5 through.

[0028] In an optional embodiment of this application, the minimum inner diameter of the mounting hole 32 can be smaller than the maximum outer diameter of the cross-section of the needle block fixing post 4, which can prevent the needle block fixing post 4 from rotating circumferentially after installation.

[0029] This embodiment achieves rapid positioning and circumferential limiting of the PCBA by setting a mounting groove adapted to the PCBA on the PCBA bracket, which facilitates the installation of the PCBA and prevents the PCBA from shifting during assembly and use. By setting a fixed step on the inner wall of the mounting hole and setting a hollow column for docking, a two-way support for the pin block fixing column is formed, ensuring that there is no axial movement after the pin block fixing column is installed, ensuring the consistency of the extension length of the PIN pin assembly, and facilitating the installation of the pin block fixing column. The hollow column for docking extends the guide length of the PIN pin assembly and prevents the PIN pin from bending and deforming when passing through the PCBA bracket.

[0030] In an optional embodiment of this application, the pin block fixing post 4 is provided with an installation section 41 adapted to the docking hollow post 34, the installation section 41 having a placement through hole 42 for the PIN pin assembly 5 to pass through; the installation section 41 is connected to a support arm 43, the support arm 43 having a snap-fit ​​step 44 that engages with the fixing step 33.

[0031] See Figure 2 and Figure 3 The pin fixing post 4 is an integrally injection-molded insulating structural component. One end of it is a cylindrical mounting section 41, the outer diameter of which matches the inner diameter of the docking hollow post 34. During assembly, it is inserted into the docking hollow post 34 to form a radial limit. The mounting section 41 has multiple parallelly arranged placement holes 42 along its axial direction, each allowing a single PIN pin to pass through. The other end of the mounting section 41 is connected to a support arm 43, which has a snap-fit ​​step 44 that engages with the fixing step 33 to enable detachment.

[0032] In one specific embodiment, the support arm 43 extends to form two cantilever structures, with a gap (fixing groove 46) between the two cantilever structures so that the two cantilever structures can move closer or further apart, and the outer surface of each cantilever structure protrudes to form a snap-fit ​​step 44.

[0033] During assembly, the pin block fixing post 4 is pushed into the mounting hole 32 from the first side of the PCBA bracket 3. The two cantilever structures in the support arm 43 can be squeezed inward by the inner wall of the mounting hole 32. When the snap step 44 passes the fixed step 33, the two cantilever structures in the support arm 43 spring back, so that the front end face of the snap step 44 and the rear end face of the fixed step 33 are tightly abutted, forming a snap connection.

[0034] In an optional embodiment of this application, the pin block fixing post 4 and the PCBA bracket 3 are made of the same insulating plastic material and have the same coefficient of thermal expansion, which can avoid changes in the mating gap caused by temperature changes.

[0035] This embodiment achieves independent positioning and physical isolation of each PIN pin by setting multiple independent placement holes on the pin block fixing post, thus avoiding contact short circuits between PIN pins; by setting a snap-fit ​​step in the installation section, a snap-fit ​​connection is formed with the fixing step of the PCBA bracket, which can achieve quick assembly without additional fasteners, and the connection strength is high and not easy to fall off.

[0036] In an optional embodiment of this application, the PIN needle assembly 5 includes multiple PIN needles 51, each PIN needle 51 having a needle body 52 in the middle, a needle tip 53 at one end, and a limiting platform 54 at the other end; the diameter of the needle body 52 is adapted to the placement hole 42, and the diameter of the limiting platform 54 is larger than the needle body 52 and abuts against the surface of the needle block fixing post 4.

[0037] PIN pin 51 can be made of a metal with good conductivity through precision machining. See [link / reference] Figure 5 Each PIN pin 51 is divided into three integrated sections: the front end is a conical pin tip 53, which is easy to insert into the through hole of PCBA2; the middle part is a cylindrical pin body 52, the diameter of which is adapted to the diameter of the placement hole 42; and the rear end is a circular limiting platform 54, the diameter of which is larger than the diameter of the pin body 52 and larger than the diameter of the placement hole 42. This ensures that when the PIN pin 51 is assembled in the placement hole 42, the size of the limiting platform 54 is larger than the size of the port of the placement hole 42, thereby abutting against the surface of the pin block fixing post 4 to achieve limiting.

[0038] During assembly, the PIN pin 51 is inserted forward from the rear end of the pin block fixing post 4 into the placement hole 42. When the limiting platform 54 abuts against the surface of the pin block fixing post 4, the PIN pin 51 is installed in place. At this time, the pin tip 53 extends from the front end of the pin block fixing post 4 and passes through the PCBA bracket 3 to the second side.

[0039] In one optional embodiment of this application, the side of the needle body 52 is tightly fitted with the inner wall of the perforation hole 42 to achieve preliminary radial positioning. The front end face of the positioning platform 54 is flat to ensure tight fit with the end face of the needle block fixing post 4.

[0040] The embodiment designs the PIN needle as a three-section integrated structure consisting of the needle tip, needle body, and limiting platform. The axial limiting of the PIN needle is achieved by the contact between the limiting platform and the surface of the needle block fixing post, preventing the PIN needle from moving forward and strictly controlling the extension length of the needle tip. The design of independent assembly of each PIN needle allows for individual replacement when a PIN needle is damaged, without having to replace the entire PIN needle assembly. Burrs and warping generated during the punching process are completely covered by the needle block fixing post, preventing short circuits. The tight fit between the needle body and the mounting hole achieves initial radial limiting.

[0041] In an optional embodiment of this application, the automotive angle sensor assembly structure further includes a PIN pin fixing pin 6, which has a plurality of fixing holes 61 for the pin body 52 to pass through, and a fixing groove 46 is provided on the outer wall of the support arm 43. The PIN pin fixing pin 6 is disposed in the mounting hole 32 and engages with the fixing groove 46.

[0042] See Figure 1 , Figure 7 and Figure 8 The PIN pin fixing pin 6 is an insulating structural component with multiple parallel fixing holes 61 on its surface. The number of fixing holes 61 is the same as the number of PIN pins 51, and they are coaxially aligned with the placement holes 42. The PIN pin fixing pin 6 is provided with a mating pin 62, the size of which is adapted to the fixing groove 46 on the outer wall of the support arm 43.

[0043] During assembly, after all PIN pins 51 are inserted into the mounting holes 42, the PIN pin retaining pin 6 is pushed in from the rear end of the pin block retaining post 4, so that the pin body 52 of each PIN pin 51 passes through the corresponding retaining hole 61. At the same time, the mating pin 62 engages in the retaining groove 46, locking the PIN pin retaining pin 6 onto the pin block retaining post 4. In an optional embodiment of this application, the PIN pin retaining pin 6 is designed to be detachable. When it is necessary to replace the PIN pin, the PIN pin retaining pin 6 can be removed simply by prying the mating pin 62 with a flathead screwdriver. The operation is simple and convenient, and there is no need to disassemble other parts.

[0044] This embodiment uses a PIN pin fixing pin with multiple fixing holes to form a secondary radial limit for all PIN pins, preventing the PIN pins from bending or shaking during use. The fixing pins at both ends of the PIN pin fixing pin engage with the fixing grooves on the outer wall of the support arm, which simultaneously restricts the inward retraction of the support arm and prevents the buckle step from accidentally disengaging from the fixing step, forming a double anti-disengagement structure. The integral fixing pin structure ensures the parallelism of all PIN pins, further improving the pin position accuracy. The detachable design facilitates rework, greatly improving production efficiency and rework convenience.

[0045] In an optional embodiment of this application, a fixing rib 45 is provided at the connection between the support arm 43 and the mounting section 41, and the fixing rib 45 abuts against the inner wall of the docking hollow column 34.

[0046] See Figure 3 Each support arm 43 has a fixed rib 45 integrally formed on the outer surface of the connection between it and the mounting section 41. When the mounting section 41 of the pin block fixing post 4 is inserted into the docking hollow post 34, the fixed rib 45 forms an interference fit with the inner wall of the docking hollow post 34, generating radial extrusion force.

[0047] In one optional embodiment of this application, the front end of the fixing rib 45 is chamfered to facilitate the insertion and docking of the hollow column 34; the fixing rib 45 adopts a symmetrical distribution design to ensure uniform force distribution.

[0048] This embodiment sets a fixing rib at the connection between the support arm and the mounting section, so that it forms an interference fit with the inner wall of the hollow column. The friction generated by the interference fit further enhances the connection strength between the pin block fixing column and the PCBA bracket, preventing rotation. At the same time, it eliminates the fit gap between the pin block fixing column and the PCBA bracket, avoids abnormal noise caused by component collisions during vehicle operation, and improves NVH performance. The symmetrically distributed fixing ribs ensure uniform force distribution and prevent the pin block fixing column from tilting.

[0049] In an optional embodiment of this application, the mounting groove 31 extends in a direction away from the PCBA support 3 to form a fixing post 38; the PCBA 2 has a guide hole 21 adapted to the fixing post 38, and the upper cover 1 has a snap cap 11 that engages with the fixing post 38.

[0050] See Figure 2 and Figures 9-11 As shown, the mounting groove 31 is integrally formed with a cylindrical fixing post 38. The height of the fixing post 38 is higher than the bottom surface of the mounting groove 31 and higher than the thickness of the PCBA2. The PCBA2 has a corresponding circular guide hole 21, the diameter of which matches the diameter of the fixing post 38. The inner surface of the top cover 1 is integrally formed with a snap cap 11 corresponding to the position of the fixing post 38. The snap cap 11 has a hollow structure and its inner wall has an annular snap.

[0051] During assembly, align the guide hole 21 of PCBA2 with the fixing post 38 and press it down to make PCBA2 fall into the placement groove 31; then fasten the top cover 1 onto the PCBA bracket 3, so that the buckle cap 11 is put on the top of the fixing post 38 and pressed down. The annular buckle on the inner wall of the buckle cap 11 engages with the annular groove at the top of the fixing post 38 to complete the fixing of the top cover 1.

[0052] This embodiment achieves precise positioning of the PCBA by setting a fixing post in the mounting slot and opening corresponding guide holes on the PCBA. The upper cover is directly connected to the fixing post by snapping the cap, so that the connection force is directly applied to the PCBA support without putting pressure on the PCBA and avoiding damage to the PCBA.

[0053] In an optional embodiment of this application, a reinforcing arm 22 extends from one end of the PCBA2, and the reinforcing arm 22 has a through hole 23 for the PIN pin assembly 5 to pass through; the inner wall or periphery of the through hole 23 is provided with a conductive contact that is electrically connected to the conductive area of ​​the PCBA2, and the PIN pin assembly 5 passes through the through hole 23 and makes contact with the conductive contact to conduct electricity.

[0054] See Figure 9 and Figure 10 One end of PCBA2 extends outward to form a rectangular reinforcing arm 22. Multiple through holes 23 are provided on the reinforcing arm 22. The number of through holes 23 is the same as the number of PIN pins 51, and they are coaxially aligned with the mounting holes 42. Each through hole 23 has a conductive contact on its inner wall. The conductive contact is electrically connected to the sensing elements and signal processing circuits on PCBA2 through PCB traces.

[0055] During assembly, when PCBA2 is installed in the mounting slot 31, the tip 53 of the PIN pin 51 passes through the corresponding through hole 23, and the outer wall of the pin body 52 makes close contact with the conductive contact of the inner wall of the through hole 23, forming a reliable electrical connection.

[0056] This embodiment enhances the strength of the PCBA in the PIN connection area by extending a reinforcing arm at one end of the PCBA, preventing the PCBA from breaking under stress. Conductive contacts are provided on the inner wall of the through-hole in the reinforcing arm, allowing the PIN to make contact with the conductive contacts as it passes through the through-hole, achieving electrical connection without soldering and simplifying the assembly process. The surface contact between the conductive contacts and the PIN results in low contact resistance and stable signal transmission. Optional soldering reinforcement processes can meet application scenarios with higher reliability requirements.

[0057] In an optional embodiment of this application, the upper cover 1 protrudes to form a relief cavity 12 corresponding to the position of the reinforcing arm 22. The relief cavity 12 covers the outside of the needle tip 53 of the PIN needle assembly 5 and leaves a gap between it and the needle tip 53.

[0058] See Figure 1 as well as Figure 11 and Figure 12One end of the top cover 1 protrudes outward to the position of the reinforcing arm 22 of PCBA2, forming a rectangular clearance cavity 12. The internal space of the clearance cavity 12 is larger than the overall size of the reinforcing arm 22 and the pin tip 53. When the top cover 1 is fastened, the clearance cavity 12 completely covers the reinforcing arm 22 and the pin tips 53 of all the pins, and there is a sufficient gap between the top surface of the cavity and the top of the pin tip 53.

[0059] In one optional embodiment of this application, the inner wall of the clearance cavity 12 is provided with multiple longitudinal reinforcing ribs to enhance the structural strength of the cavity and prevent the top cover from deforming.

[0060] This embodiment provides comprehensive physical protection for the PIN needle tip by setting a raised clearance cavity at the position corresponding to the reinforcing arm on the upper cover. This prevents the needle tip from bending or breaking due to collisions with external objects, while also preventing dust, moisture, and other contaminants from directly adhering to the needle tip surface. The safety gap reserved between the cavity and the needle tip prevents direct contact between the upper cover and the PIN needle, preventing short circuit faults and ensuring electrical safety. The raised structure also increases the local strength of the upper cover and improves its impact resistance.

[0061] Reference Figure 2 and Figure 11 As shown, multiple snap-fit ​​grooves 13 are provided on the outer peripheral side wall of the upper cover 1, and correspondingly, multiple cover-closing steps 39 are provided on the PCBA bracket 3, so that the upper cover 1 and the PCBA bracket 3 are tightly connected by the multiple snap-fit ​​grooves 13 and the multiple cover-closing steps 39 engaging.

[0062] Reference Figure 1 and Figure 12 Furthermore, the hollow column 34 of the PCBA bracket 3 is also provided with a sealing ring 7. The sealing ring 7 is located at the interface between the hollow column 34 and the mounting hole 32, which can form a reliable sealing and protective barrier to prevent external dust, moisture and other pollutants from entering the gap between the hollow column 34 and the mounting hole 32, and avoid damage to the PCBA2 and the PIN pin assembly 5.

[0063] Meanwhile, the sealing ring 7 can use its own elasticity to provide pre-tightening force and buffering effect to compensate for processing and assembly errors, assist in the positioning and fastening of the pin block fixing post 4 and the PCBA bracket 3, prevent the pin block fixing post 4 from loosening, and thus improve the reliability of this assembly structure.

[0064] This application also provides an assembly process for an automotive angle sensor, based on the automotive angle sensor assembly structure constructed by the above-described scheme, the assembly process including: The automotive angle sensor body is assembled from a split top cover 1, PCBA 2, PCBA bracket 3, pin block fixing post 4, and PIN pin assembly 5. First, the pin block fixing post 4 is assembled to the bottom of the PCBA bracket 3. Then, the PIN pin assembly 5 is assembled and built into the pin block fixing post 4, with the pin tip of the PIN pin assembly 5 extending out of the top surface of the PCBA bracket 3. The PIN pin assembly 5 is fixed by the PIN pin fixing pin 6. Next, PCBA 2 is installed on the top of the PCBA bracket 3 and makes contact with the pin tip of the PIN pin assembly 5 for conduction. Further, the top cover 1 is placed on top of the PCBA bracket 3, covering PCBA 1 and PIN pin assembly 5. Finally, the sealing ring 7 is installed between the mating surfaces of the top cover 1 and the PCBA bracket 3 to assemble the automotive angle sensor body, which can be directly used for installation and testing, thereby improving production efficiency and simplifying the structure.
