Description

Technical Field

[0001] This utility model relates to the field of domain controller manufacturing, and more particularly to a domain controller and a mobile platform using the domain controller. Background Technology

[0002] Currently, based on high-performance computing chips, the vehicle domain controller integrates cockpit domain functions and intelligent driving domain functions. Cockpit domain functions mainly refer to managing and controlling the in-vehicle digital instrument panel and information and entertainment system, while intelligent driving domain functions mainly refer to receiving and processing data from various sensors such as cameras, radar, and lidar in real time to achieve accurate perception of the surrounding environment and perform path planning, obstacle avoidance strategies, and speed control to ensure that the vehicle can drive safely and efficiently.

[0003] Because vehicle-mounted domain controllers are more complex, various problems inevitably arise during use. Most software issues can be analyzed, debugged, and troubleshooted by connecting to a host computer via the domain controller's built-in Ethernet interface. However, in special cases, a separate debugging interface is required for debugging (finding and eliminating hardware faults), such as when the underlying software fails to function properly or the PCB (Printed Circuit Board) cannot be powered on correctly.

[0004] like Figure 1 As shown, Chinese utility model patent CN220420895U discloses a phased array antenna structure, including a base shell 610, heat dissipation teeth 620, radome 100, antenna receiving array 210, antenna transmitting array 220, up-conversion module 320, down-conversion module 310, baffle 510, and fan assembly 520. An external connector 420 for connecting test cables is provided on the side of the base shell 610, with the connection port of the external connector 420 facing outwards relative to the side of the base shell 610. During overall testing, the test cables can be directly connected to the external connector 420, avoiding the need to disassemble and reassemble the radome 100, thus improving testing efficiency. However, this phased array antenna structure has the following drawbacks:

[0005] The additional external connector 420 for debugging is still retained, which increases the additional material cost and PCB placement cost. For products that have entered a stable mass production state, the utilization rate of external connector 420 is not high, which will cause a lot of waste.

[0006] like Figure 2As shown, Chinese invention patent application CN106058419A discloses an antenna assembly structure including a sealing cover 210, a sealing ring 220, a sealing port 230, and a reserved test point 240. The reserved test point 240 is located inside the test port corresponding to the internal circuit switch position of the antenna radome. The sealing port 230 is located at the test port. The sealing cover 210 and the sealing port 230 are detachably fitted. The sealing ring 220 is located between the sealing cover 210 and the sealing port 230, serving to seal, waterproof, and prevent loosening. However, this antenna assembly structure has the following defects:

[0007] After removing the sealing cover 210, a metal probe needs to be inserted into the sealing port 230 to connect the reserved test point 240. Since there is no additional structure to fix the metal probe, the metal probe is easy to lose connection with the reserved test point 240 during debugging (i.e., debugging is inconvenient and inefficient).

[0018] In some embodiments of this utility model, a positioning hole or positioning groove is formed on one of the outer wall of the housing and the first antenna cover, and a positioning pin is formed on the other, so that the positioning hole or positioning groove first engages with the positioning pin, and then the elastic hook engages with the engaging protrusion.

[0019] In some embodiments of this utility model, the locating pin has a rough surface and / or the tail of the locating pin is thicker than the end, so that it can be interference-fitted with the locating hole or locating groove.

[0020] In some embodiments of this utility model, the domain controller further includes a second antenna cover, the first antenna cover and the second antenna cover are interchangeable, and the second antenna cover does not have the test window.

[0021] A second aspect of this utility model provides another domain controller comprising:

Another domain controller provided by this invention features two interchangeable first and second antenna covers. The second antenna cover differs from the first antenna cover only in that it lacks a test window; the rest of the design is identical. For example, the first antenna cover can be obtained by further processing (creating a test window) based on the second antenna cover, eliminating the cost of separate mold manufacturing.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0053] like Figure 3-8 As shown, one embodiment of this utility model provides a domain controller 100, including a housing 10 having a first receiving cavity 11a, the edge of which forms an opening 12; a circuit board 20 having an onboard antenna region 20a, on which a reserved test point 21 is provided, a portion of which is disposed in the first receiving cavity 11a, the onboard antenna region 20a being exposed by the opening 12; a first antenna cover 30 detachably disposed on the housing 10, the first antenna cover 30 having a test window 31, the first antenna cover 30 being able to cover the opening 12 and forming a second receiving cavity 11b with the housing 10, the onboard antenna region 20a being accommodated in the second receiving cavity 11b, the reserved test point 21 being able to be aligned with the test window 31 (the reserved test point 21 is exposed from the test window 31); and a test connector 50 having a probe 51, the test connector 50 being installed in the test window 31, the probe 51 being used to connect to the reserved test point 21.

[0054] For example, the circuit board 20 can be a PCBA (Printed Circuit Board Assembly) board, which is a blank PCB board that has been mounted by SMT (Surface Mount Technology).

[0055] For example, the housing 10, the first antenna cover 30, and the test connector 50 can be made of relatively robust non-metallic materials (e.g., plastic) or metallic materials. Specifically, considering the need to provide good protection for the onboard antenna area 20a while not obstructing the signal of the antenna chip 22, the first antenna cover 30 is preferably made of a non-metallic material (e.g., plastic). Furthermore, the housing 10, the first antenna cover 30, and the test connector 50 can all be manufactured using processes such as die casting, injection molding, or 3D printing.

[0056] For example, the antenna chip 22 can be surface-mounted onto the PCBA board via SMT, eliminating the need to fix the antenna module to the housing surface and connect it to the PCBA board via a wiring harness, thus providing greater reliability. When stacking PCBA boards, attention must be paid to the clearance around the antenna chip 22, and corresponding openings should be made in the housing 10 to ensure the performance of the antenna chip 22.

[0057] In some embodiments of this application, there are three antenna chips 22 mounted on the PCBA board (three onboard antenna regions 20a), thus three openings 12 are also formed at corresponding positions in the housing 10. Two of the openings 12 are located on one side of the housing 10, and the other opening 12 is located on the other side of the housing 10. A reserved test point 21 can be set on any of the onboard antenna regions 20a.

[0058] In other embodiments, the number of openings 12 can be varied depending on the number of onboard antenna regions 20a; for example, there can be one or two openings 12. Reserved test points 21 can also be located on multiple onboard antenna regions 20a.

[0059] In this embodiment, for ease of assembly, the housing 10 includes a detachable upper housing 10a and a lower housing 10b, which together form a first receiving cavity 11a, within which the circuit board 20 is disposed. The upper housing 10a, the lower housing 10b, and the circuit board 20 can be fixed together by screws 60.

[0060] In other embodiments, the housing 10 may be integrally formed, with a first receiving cavity 11a formed inside, and the circuit board 20 may be disposed in the first receiving cavity 11a (for example, the circuit board 20 may be inserted into the first receiving cavity 11a from one side of the housing 10, and the insertion port may be provided with a closable cover). The housing 10 and the circuit board 20 may be fixed to each other by screws 60.

[0061] In this embodiment, the opening 12 is mainly formed on the side edge of the shell 10 and extends toward the top surface of the upper shell 10a and the bottom surface of the lower shell 10b, that is, the cross-section of the opening 12 is approximately “]” shaped.

[0062] In other embodiments, the opening 12 may be formed primarily on the side edge of the housing 10 and extend toward the top surface of the upper housing 10a, but not toward the bottom surface of the lower housing 10b, i.e., the cross-section of the opening 12 is approximately “𠃍” shaped.

[0063] For example, the test connector 50 can be detachably installed on the test window 31 of the first antenna cover 30 by means of plugging, snap-fitting, interference fit, etc. The test connector 50 can also be installed on the test window 31 of the first antenna cover 30 by means of welding, gluing, etc. That is to say, the test connector 50 and the first antenna cover 30 can be combined into a whole first, and then installed together on the opening 12, so that the probe 51 on the test connector 50 can be connected to the reserved test point.

[0064] Those skilled in the art will understand that the domain controller 100 directly sets reserved test points on the PCB without the need for additional debugging interfaces, thus saving material costs. Furthermore, the test window 31 on the first antenna cover 30 can provide positioning for the test connector 50, preventing the test connector 50 from tilting left or right and losing connection with the reserved test point 21. This results in high testing and / or maintenance efficiency, convenient operation, and strong reliability.

[0065] Furthermore, the domain controller 100 also includes a second antenna cover 40, the first antenna cover 30 and the second antenna cover 40 being interchangeable, and the second antenna cover 40 not having a test window 31.

[0066] Combination Figure 10 As shown, under normal circumstances (or in working condition), the domain controller 100 is equipped with a second antenna cover 40 (without a test window 31), thus enclosing the reserved test point 21 and the antenna chip 22 within the second receiving cavity 11b. When the domain controller 100 malfunctions, the second antenna cover 40 is removed from the housing 10 (see...). Figure 10 ①), and replace the first antenna cover 30 (with test window 31) with the same shape as the second antenna cover 40. The test window 31 is aligned with the reserved test point 21 (see Figure 10 ②), and then connect the test connector 50 and the test window 31 together (e.g., plug-in, snap-fit, interference fit, etc.), so that the probe 51 on the test connector 50 is connected to the reserved test point 21 (see Figure 10 ③), thereby connecting the domain controller 100 to the host computer via test connector 50. The host computer can perform fault location and diagnosis based on the signals returned from the reserved test point 21. After completing the test and / or repair, disconnect the test connector 50 and the first antenna cover 30 in sequence, and then replace the second antenna cover 40 (see Figure 10 ④).

[0067] For example, the second antenna cover 40 can be made of a plastic material that provides good protection for the onboard antenna area 20a without obstructing the signal of the antenna chip 22.

[0068] Those skilled in the art should understand that the only difference between the second antenna cover 40 and the first antenna cover 30 is that the second antenna cover 40 does not have the test window 31; otherwise, their shapes are completely identical. For example, the first antenna cover 30 can be obtained by further processing (opening the test window 31) based on the second antenna cover 40, saving the cost of separate mold manufacturing.

[0069] Special reference Figure 8 As shown, the test window 31 further has an asymmetrical shape so that the test connector 50 can be coupled to the test window 31 in a predetermined direction.

[0070] Those skilled in the art should understand that the test window 31 can be approximately convex, and the cross-section of the test connector 50 is also convex in the same size, so that the test connector 50 can only be coupled to the test window 31 in a predetermined direction, and the probe 51 connects precisely to the reserved test point 21. The test window 31 can also be other asymmetrical shapes, such as "E" shape, "F" shape, etc., and the cross-section of the test connector 50 is also "E" shape, "F" shape, etc., in which case the test window 31 and the test connector 50 actually form a foolproof design.

[0071] Combination Figure 9 As shown, a protrusion 52 is formed on one end of the test connector 50, and the probe 51 is disposed on the protrusion 52. The test connector 50 can be inserted into the test window 31 by means of the protrusion 52, and the probe 51 can just abut against the reserved test point 21.

[0072] Those skilled in the art should understand that the test window 31 can be roughly convex, and the protrusion 52 is also convex in the same size, so that the test connector 50 can only be inserted into the test window 31 in a predetermined direction, and the rest of the test connector 50 cannot enter the test window 31. The probe 51 just abuts against the reserved test point 21. The protrusion 52 not only serves to fix the test connector 50 on the test window 31, but also effectively prevents the test connector 50 from being inserted too deeply into the test window 31, which would cause the probe 51 and the reserved test point 21 to be squeezed and / or damaged by friction.

[0073] Furthermore, the reserved test point 21 is a metal contact, and the probe 51 is a metal probe.

[0074] For example, the test connector 50 can be quickly manufactured using 3D printing technology. The end of the test connector 50 has a hole that can accommodate the metal probe 51, which facilitates the placement of the metal probe 51 and wires in the hole in subsequent procedures.

[0075] Those skilled in the art should understand that multiple metal contacts can be manufactured simultaneously through circuit board manufacturing processes such as SMT, without the need for additional mounting and debugging interfaces as in existing technologies. Such metal contacts can save space, reduce processes, and lower manufacturing costs.

[0076] Special reference Figure 6a and 6b As shown, an antenna chip 22 is provided on the onboard antenna area 20a, and the antenna chip 22 and the reserved test point 21 are located on opposite sides of the circuit board 20.

[0077] Those skilled in the art should understand that, compared to placing the antenna chip 22 and the reserved test point 21 on the same side of the circuit board 20, placing them on opposite sides of the circuit board 20 can prevent the probe 51 from accidentally touching the antenna chip 22 after the test connector 50 and the test window 31 are combined, thereby improving reliability.

[0078] Combination Figure 11-13 as well as Figure 14a , 14b As shown, a water guide groove 13 is further provided on the outer wall 10c of the housing 10 forming the opening 12. A locking protrusion 14 is formed at the groove opening 13a of the water guide groove 13. A pair of elastic hooks 32 are provided on the first antenna cover 30. The elastic hooks 32 can extend into the water guide groove 13 and engage with the locking protrusion 14.

[0079] As mentioned above, the only difference between the first antenna cover 30 and the second antenna cover 40 is that the second antenna cover 40 does not have a test window 31, and therefore the second antenna cover 40 is also provided with a flexible hook 41.

[0080] For example, the water channel 13 is formed in the width direction of the entire opening 12 (e.g. Figure 12 In the D direction, it can collect droplets that seep into the second receiving cavity 11b through the gap between the first antenna cover 30 (second antenna cover 40) and the outer wall 10c of the housing 10 in the water guide trough 13, and then discharge them out of the second receiving cavity 11b through the trough opening 13a.

[0081] For example, the height of the opening 13a of the water channel 13 on the outer wall 10c of the housing 10 is lower than the height of the rest of the portion.

[0082] In this embodiment, a step is formed at the opening 13a of the water guide channel 13, so that the height of the opening 13a is lower than the height of the rest of the channel.

[0083] In other embodiments, the water channel 13 may be formed into multiple steps, or the water channel 13 may be configured as a slope similar to a slide, so that the height of the channel opening 13a is lower than the height of the rest of the channel.

[0084] For example, a flange 13b is formed on the outer wall 10c of the housing 10, and a water-blocking rib 13c is provided at the end of the flange 13b. The outer wall 10c, the flange 13b and the water-blocking rib 13c form a water channel 13 with an opening facing away from the onboard antenna region 20a.

[0085] In this embodiment, the engaging protrusion 14 is formed on the outer wall 10c of the housing 10 and located at the opening 13a of the water guide channel 13. The engaging protrusion 14 narrows the water guide channel 13 at the opening 13a, while the water-blocking rib 13c limits the elastic hook 32 of the first antenna cover 30 (the elastic hook 41 of the second antenna cover 40) from the other side, allowing the elastic hook 32 (elastic hook 41) to more easily enter the opening 13a and engage with the engaging protrusion 14. After engagement, the elastic hook 32 (elastic hook 41) will not completely block the opening 13a.

[0086] In other embodiments, the engaging protrusion 14 may be formed on the water-blocking rib 13c and located at the opening 13a of the water-guiding channel 13. Similarly, the engaging protrusion 14 narrows the water-guiding channel 13 at the opening 13a, and the outer wall 10c of the housing 10 limits the elastic hook 32 of the first antenna cover 30 (the elastic hook 41 of the second antenna cover 40) from the other side, allowing the elastic hook 32 (elastic hook 41) to more easily enter the opening 13a and engage with the engaging protrusion 14. After engagement, the elastic hook 32 (elastic hook 41) will not completely block the opening 13a.

[0087] Those skilled in the art should understand that the circuit board 20 is first placed in the first receiving cavity 11a of the housing 10, and then the first antenna cover 30 (second antenna cover 40) is directly covered on the opening 12. The elastic hooks 32 (elastic hooks 41) on the first antenna cover 30 (second antenna cover 40) are directly engaged with the engaging protrusion 14 at the opening 13a of the water guide trough 13, so that the first antenna cover 30 (second antenna cover 40) can be directly detached from the housing 10. By adjusting the fit tolerance between the elastic hooks 32 (elastic hooks 41) and the engaging protrusion 14, their engagement tightness can be adjusted.

[0088] Furthermore, a positioning hole or positioning groove 15 is formed on one of the outer wall 10c of the housing 10 and the first antenna cover 30, and a positioning pin 33 is formed on the other, so that the positioning hole or positioning groove 15 first engages with the positioning pin 33, and then the elastic hook 32 engages with the engaging protrusion 14.

[0089] As mentioned above, the only difference between the first antenna cover 30 and the second antenna cover 40 is that the second antenna cover 40 does not have a test window 31, and therefore the second antenna cover 40 is also provided with a positioning pin 42.

[0090] In this embodiment, the first antenna cover 30 (the second antenna cover 40) is approximately in the shape of "]", with two positioning pins 33 (positioning pins 42) formed at its upper part and one positioning pin 33 (positioning pin 42) formed at its lower part, and the aforementioned elastic hook 32 (elastic hook 41) formed in its middle part. Correspondingly, two positioning holes or positioning grooves 15 are formed on the outer wall 10c of the upper housing 10a, and one positioning hole or positioning groove 15 is formed on the outer wall 10c of the lower housing 10b.

[0091] In other embodiments, the first antenna cover 30 (the second antenna cover 40) is generally in the shape of "]", with a positioning pin 33 (positioning pin 42) formed at its upper part, two positioning pins 33 (positioning pins 42) formed at its lower part, and the aforementioned elastic hook 32 (elastic hook 41) formed in its middle part. Correspondingly, a positioning hole or positioning groove 15 is formed on the outer wall 10c of the upper housing 10a, and two positioning holes or positioning grooves 15 are formed on the outer wall 10c of the lower housing 10b.

[0092] In other embodiments, positioning pins 33 (positioning pins 42) may be formed on the outer wall 10c of the upper housing 10a and the outer wall 10c of the lower housing 10b, and positioning holes or positioning grooves 15 may be formed on the first antenna cover 30 (second antenna cover 40).

[0093] In this embodiment, the middle part of the first antenna cover 30 (the second antenna cover 40) has an irregular shape, and multiple auxiliary positioning features 34 (auxiliary positioning features 43) are formed thereon. The auxiliary positioning features 34 (auxiliary positioning features 43) can be in the shape of protrusions, steps, hooks, etc. Multiple matching auxiliary guiding features can be formed on the outer wall 10c of the housing 10.

[0094] Those skilled in the art will understand that the positioning hole or positioning groove 15 and the positioning pin 33 (positioning pin 42) can provide guidance for the assembly of the first antenna cover 30 (second antenna cover 40) and the housing 10, so that the engagement of the elastic hook 32 (elastic hook 41) with the engaging protrusion 14 can be carried out smoothly in subsequent processes. The first antenna cover 30 (second antenna cover 40) can be more easily directly assembled onto the housing 10 or directly removed from the housing 10, which is beneficial for testing and / or repairing the domain controller 100 after replacing the second antenna cover 40 with the first antenna cover 30.

[0095] Furthermore, the locating pin 33 (locating pin 42) has a rough surface and / or the tail of the locating pin 33 (locating pin 42) is thicker than the end, so that it can be interference-fitted with the locating hole or locating groove 15.

[0096] In this embodiment, two positioning pins 33 (positioning pins 42) are formed on the upper part of the first antenna cover 30 (second antenna cover 40). The two positioning pins 33 (positioning pins 42) have rough surfaces (e.g., tiny particles are formed on their surfaces). A positioning pin 33 (positioning pin 42) is formed on the lower part of the first antenna cover 30 (second antenna cover 40). The thickness of the tail of the positioning pin 33 (positioning pin 42) is greater than that of the end.

[0097] In other embodiments, all locating pins 33 (locating pins 42) have a rough surface, or all locating pins 33 (locating pins 42) have a thickness at the tail greater than at the end.

[0098] Those skilled in the art should understand that regardless of whether the positioning pin 33 (positioning pin 42) has a rough surface or the thickness of the tail of the positioning pin 33 (positioning pin 42) is greater than that of the end, it can provide a damping feel during the snapping process between the first antenna cover 30 (second antenna cover 40) and the housing 10, prevent the first antenna cover 30 (second antenna cover 40) from shaking, and enhance its vibration reliability.

[0099] Furthermore, at least one type of reinforcing rib 35 is formed on the first antenna cover 30.

[0100] As mentioned above, the only difference between the first antenna cover 30 and the second antenna cover 40 is that the second antenna cover 40 does not have a test window 31. Therefore, the second antenna cover 40 is also provided with at least one type of reinforcing rib 44.

[0101] In this embodiment, the first antenna cover 30 (second antenna cover 40), which is roughly in the shape of "]", has a plurality of hexagonal reinforcing ribs 35 (reinforcing ribs 44) arranged in a grid pattern in the middle. The first antenna cover 30 (second antenna cover 40) is also provided with a plurality of fin-shaped reinforcing ribs 35 (reinforcing ribs 44) connecting the upper and middle parts, and triangular reinforcing ribs 35 (reinforcing ribs 44) connecting the lower and middle parts.

[0102] Those skilled in the art will understand that this application does not limit the shape of the first antenna cover 30 (second antenna cover 40), as long as it can cover the opening 12. Therefore, one or more types of reinforcing ribs 35 (reinforcing ribs 44) can be provided according to the specific shape of the first antenna cover 30 (second antenna cover 40), thereby improving the structural strength of the first antenna cover 30 (second antenna cover 40), reducing the deformation of the first antenna cover 30 (second antenna cover 40) during installation and use, and better protecting the circuit board 20 (especially the onboard antenna area 20a).

[0103] Another embodiment of the present invention provides a domain controller 100, including a housing 10 having a first receiving cavity 11a, the edge of the housing 10 having an opening 12; a circuit board 20 having an onboard antenna region 20a, the onboard antenna region 20a having a reserved test point 21, a portion of the circuit board 20 being disposed in the first receiving cavity 11a, the onboard antenna region 20a being exposed by the opening 12; a first antenna cover 30 and a second antenna cover 40 detachably disposed on the housing 10, the first antenna cover 30 having a test window 31, the first antenna cover 30 being able to cover the opening 12 and forming a second receiving cavity 11b with the housing 10, the onboard antenna region 20a being accommodated in the second receiving cavity 11b, the reserved test point 21 being aligned with the test window 31, the first antenna cover 30 and the second antenna cover 40 being interchangeable, the second antenna cover 40 not having a test window 31.

[0104] Those skilled in the art will understand that the domain controller 100 has two interchangeable first antenna cover 30 and second antenna cover 40. The only difference between the second antenna cover 40 and the first antenna cover 30 is that the second antenna cover 40 does not have a test window 31; otherwise, their shapes are identical. For example, the first antenna cover 30 can be obtained by further processing (opening the test window 31) based on the second antenna cover 40, saving the cost of separate mold manufacturing.

[0105] Furthermore, the domain controller 100 also includes a test connector 50 with a probe 51, which is mounted on the test window 31 and the probe 51 is used to connect to a reserved test point 21.

[0106] Those skilled in the art will understand that the domain controller 100 directly sets reserved test points on the PCB without the need for additional debugging interfaces, thus saving material costs. Furthermore, the test window 31 on the first antenna cover 30 can provide positioning for the test connector 50, preventing the test connector 50 from tilting left or right and losing connection with the reserved test point 21. This results in high testing and / or maintenance efficiency, convenient operation, and strong reliability.

[0107] Furthermore, the test window 31 has an asymmetrical shape so that the test connector 50 can be coupled to the test window 31 in a predetermined direction.

[0108] Furthermore, a protrusion 52 is formed on one end of the test connector 50, and the probe 51 is disposed on the protrusion 52. The test connector 50 can be inserted into the test window 31 by means of the protrusion 52, and the probe 51 can just abut against the reserved test point 21.

[0109] Furthermore, the reserved test point 21 is a metal contact, and the probe 51 is a metal probe.

[0110] Furthermore, an antenna chip 22 is provided on the onboard antenna area 20a, and the antenna chip 22 and the reserved test point 21 are located on opposite sides of the circuit board 20.

[0111] Furthermore, a water guide groove 13 is provided on the outer wall of the housing 10 that forms the opening 12. A locking protrusion 14 is formed at the groove opening 13a of the water guide groove 13. A pair of elastic hooks 32 are provided on the first antenna cover 30. The elastic hooks 32 can extend into the water guide groove 13 and engage with the locking protrusion 14.

[0112] Furthermore, a positioning hole or positioning groove 15 is formed on one of the outer wall 10c of the housing 10 and the first antenna cover 30, and a positioning pin 42 is formed on the other, so that the positioning hole or positioning groove 15 first engages with the positioning pin 42, and then the elastic hook 32 engages with the engaging protrusion 14.

[0113] Furthermore, the locating pin 42 has a rough surface and / or the tail of the locating pin 42 is thicker than the end, so that it can be interference-fitted with the locating hole or locating groove 15.

[0114] Those skilled in the art should understand that the design details of the above-mentioned components in the domain controller 100 in this embodiment can be found in the foregoing embodiments, and will not be repeated here.

[0115] Furthermore, the aforementioned domain controller can also be used in a mobile platform. The mobile platform can be a car, unmanned aerial vehicle (UAV), remote-controlled car, unmanned boat, or robot. The car can be a driverless vehicle or a manned vehicle, and the UAV can be a drone or other unmanned aerial vehicle. Of course, the mobile platform is not limited to the mobile platforms listed above and can also be other mobile platforms.

[0116] Those skilled in the art will understand that, because the mobile platform employs the aforementioned domain controller 100, it possesses all the technical effects brought about by the domain controller 100. For example, the domain controller 100 directly sets reserved test points on the PCB without the need for additional debugging interfaces, saving material costs. Furthermore, the test window 31 on the first antenna cover 30 can provide positioning for the test connector 50, preventing the test connector 50 from tilting left or right and losing connection with the reserved test point 21, resulting in high testing and / or maintenance efficiency, convenient operation, and strong reliability.
