Description

TECHNICAL FIELD

[0001] The utility model relates to the field of domain controller manufacturing, especially to a domain controller with waterproof function and a movable platform using the domain controller. BACKGROUND

[0002] At present, based on high-performance computing chips, the vehicle-mounted domain controller integrates the cabin domain function and the intelligent driving domain function. The cabin domain function mainly refers to managing and controlling the digital instrument panel and information, entertainment system and the like in the vehicle, and the intelligent driving domain function mainly refers to receiving and processing data from multiple sensors such as cameras, radars, laser radars in real time, realizing accurate perception of the surrounding environment, and performing path planning, obstacle avoidance strategy, vehicle speed control and the like, so as to ensure that the vehicle can safely and efficiently travel.

[0003] The Chinese invention patent application with the publication number CN113794051A discloses a host structure with an on-board antenna, which comprises an upper cover, a lower cover, a circuit board and an antenna cover. The upper cover and the lower cover can cooperate to form a mounting cavity, and the mounting cavity is provided with an antenna outlet. The circuit board is arranged in the mounting cavity, and the antenna mounting part near the four corners of the circuit board extends out of the antenna outlet. The triangular antenna cover is connected with the upper cover and the lower cover in a clamping manner, thereby covering the antenna mounting part of the circuit board. A plurality of positioning grooves are arranged on the antenna cover at intervals, and elastic arms are formed between adjacent positioning grooves, thereby enhancing the deformation ability of the antenna cover. However, the host structure with the on-board antenna has the following defects:

[0004] 1. Water droplets and dust are more likely to enter the mounting cavity through the positioning grooves on the antenna cover, damaging the circuit board.

[0005] 2. The antenna cover is fixedly installed after being clamped by the upper cover and the lower cover from both sides. When disassembling, the upper cover and the lower cover need to be removed first, and then the antenna cover can be removed. The operation is complicated, which is not conducive to production line assembly and is not conducive to maintenance of the on-board antenna in the later period.

[0006] 3. The triangular antenna cover and the on-board antenna are installed at the four corner positions of the PCBA board, which has a strong constraint on the layout of the on-board antenna. Moreover, the plastic antenna cover protrudes outside the metal upper cover and lower cover, and is easy to break when falling or colliding, thereby losing the protection effect on the on-board antenna.

[0008] 1, antenna cover is directly installed on main shell in snap-fit and plug-in mode, which is inevitable to form a small gap between antenna cover and main shell, so that water droplets and dust are easily penetrated into chamber through antenna cover, and then damage circuit board.

[0009] 2, triangular antenna cover and on-board antenna are installed at four corner positions of PCBA board, which has strong constraint on the layout of on-board antenna, and antenna cover protrudes outside main shell, which is easy to break when falling or colliding, thereby losing the protection effect on on-board antenna.

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] As Figures 1-9As shown, the utility model discloses an embodiment provides a kind of domain controller 100, it mainly includes shell 10, circuit board 20 and antenna cover 30.Wherein, shell 10 has first accommodating cavity 11a, the edge of shell 10 is formed with open 12, and water guide groove 13 is provided on the outer wall 10a of shell 10 formed with open 12.Circuit board 20 has onboard antenna area 20a, and a part of circuit board 20 is set in first accommodating cavity 11a, and onboard antenna area 20a is exposed by open 12 and adjacent water guide groove 13.Antenna cover 30 is detachably set on shell 10, and antenna cover 30 can be covered on open 12 and form second accommodating cavity 11b with shell 10, and onboard antenna area 20a and water guide groove 13 are accommodated in second accommodating cavity 11b, and the slot 13a of water guide groove 13 is communicated with outside.

[0041] Exemplarily, circuit board 20 can be PCB empty board, and PCBA board (Printed Circuit Board Assembly, for short PCBA) is mounted on SMT (Surface Mount Technology).

[0042] Exemplarily, antenna chip can be pasted on PCBA board by SMT, and it is not necessary to fix antenna module on the surface of shell and then connect with PCBA board through wire harness, so as to have stronger reliability. When PCBA board is stacked, it is necessary to pay attention to the clearance near antenna chip, and the corresponding position of shell 10 is perforated to avoid, so as to guarantee the performance of antenna chip.

[0043] Exemplarily, shell 10 can be made of relatively solid plastic or metal material, and antenna cover 30 can be made of plastic material which has good protection effect on onboard antenna area 20a and does not shield antenna chip signal.

[0044] In the embodiment, the antenna chip pasted on PCBA board has three (onboard antenna area 20a has three), therefore, three openings 12 are also formed at the corresponding positions of shell 10. Two of the openings 12 are located at one side of shell 10, and the other opening 12 is located at the other side of shell 10.

[0045] In other embodiments, the number of openings 12 can be changed according to the number of onboard antenna area 20a, for example, the opening 12 can be one or two.

[0046] In the embodiment, in order to facilitate assembly, shell 10 includes detachable upper shell 10b and lower shell 10c, and the upper shell 10b and the lower shell 10c enclose first accommodating cavity 11a, and circuit board 20 is arranged in first accommodating cavity 11a. The upper shell 10b, the lower shell 10c and the circuit board 20 can be fixed to each other by screws.

[0047] 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.

[0048] In this embodiment, the upper housing 10b has a cooling channel 10d, and the coolant or cold air in the cooling channel 10d can dissipate heat from the circuit board 20.

[0049] In other embodiments, the upper housing 10b may also be provided with an air-cooled heat dissipation module (not shown) or a passive heat dissipation module (not shown).

[0050] 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 10b and the bottom surface of the lower shell 10c, that is, the cross-section of the opening 12 is approximately “]” shaped.

[0051] 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 10b, but not toward the bottom surface of the lower housing 10c, that is, the cross-section of the opening 12 is approximately “𠃍” shaped.

[0052] In this embodiment, the water guide channel 13 is formed along the width direction of the entire opening 12 (e.g., Figure 2 (in the D direction), it can collect droplets that seep into the second receiving cavity 11b through the gap between the antenna cover 30 and the outer wall 10a 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.

[0053] Those skilled in the art should understand that when liquid drips onto the surface of the housing 10 or the antenna cover 30, some of the liquid seeps into the second receiving cavity 11b through the gap between the antenna cover 30 and the outer wall 10a. This liquid will not drip directly onto the PCBA board, but will flow into the water guide trough 13 and finally be discharged out of the second receiving cavity 11b through the trough opening 13a, thereby avoiding damage to the PCBA board and the antenna chip. This domain controller 100 can meet the IP5K2 level waterproof requirement.

[0054] Special reference Figures 5-7 As shown, further, the height of the opening 13a of the water guide channel 13 on the outer wall 10a of the housing 10 is lower than the height of the rest of the part.

[0055] 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.

[0056] In other embodiments, the water guide groove 13 can be formed with multiple levels of steps, or the water guide groove 13 can be arranged in a slope shape similar to a slide, so that the height of the slot 13a is lower than the rest of the water guide groove 13.

[0057] Those skilled in the art should understand that arranging the slot 13a of the water guide groove 13 at a lower position is conducive to the flow of liquid in the water guide groove 13, and quickly discharging the liquid outside the second accommodating cavity 11b via the slot 13a, avoiding the liquid spilling out of the water guide groove 13 and splashing on the PCBA board or the antenna chip.

[0058] Continuing to refer to Figures 5-7 As shown, further, a flange 13b is formed on the outer wall 10a of the shell 10, and an end of the flange 13b is provided with a water retaining rib 13c, and the outer wall 10a, the flange 13b and the water retaining rib 13c enclose a water guide groove 13 with an opening facing away from the antenna on-board area 20b.

[0059] Further, after the antenna cover 30 covers the opening 12, the end of the water retaining rib 13c protrudes from the antenna cover 30, so that the depth of the slot 13a of the water guide groove 13 is greater than the depth of the rest of the water guide groove 13.

[0060] Those skilled in the art should understand that the height of the water retaining rib 13c can be adjusted as needed, and the height of the water retaining rib 13c determines the depth of the water guide groove 13. Without affecting the detachable covering of the antenna cover 30 on the opening 12, the water retaining rib 13c can be appropriately increased in height. In particular, the height and width of the water retaining rib 13c are increased at the slot 13a of the water guide groove 13, so that the water retaining rib 13c slightly protrudes from the antenna cover 30, avoiding droplets from splashing into the second accommodating cavity 11b from the side, thereby better protecting the PCBA board and the antenna chip.

[0061] Further, the water guide groove 13 is in a "U" shape, and a clamping protrusion 14 is formed at the slot 13a of the water guide groove 13, and a pair of elastic clamping hooks 31 are arranged on the antenna cover 30, and the elastic clamping hooks 31 can extend into the water guide groove 13 and be clamped with the clamping protrusion 14.

[0062] In this embodiment, the clamping protrusion 14 is formed on the outer wall 10a of the shell 10 and located at the slot 13a of the water guide groove 13. The clamping protrusion 14 narrows the water guide groove 13 at the slot 13a, and the water retaining rib 13c limits the elastic clamping hooks 31 from the other side, so that the elastic clamping hooks 31 can more easily enter the slot 13a and be clamped with the clamping protrusion 14. After clamping, the elastic clamping hooks 31 do not completely block the slot 13a.

[0063] In other embodiments, the snap protrusion 14 can be formed on the water barrier 13c at the slot opening 13a of the water guide groove 13. Similarly, the snap protrusion 14 narrows the water guide groove 13 at the slot opening 13a, and the outer wall 10a of the shell 10 limits the elastic snap hook 31 from the other side, so that the elastic snap hook 31 can more easily enter the slot opening 13a and be snap-coupled with the snap protrusion 14. After the snap coupling is completed, the elastic snap hook 31 does not completely block the slot opening 13a.

[0064] As can be understood by those skilled in the art, the circuit board 20 is first arranged in the first accommodating cavity 11a of the shell 10, and then the antenna cover 30 is directly arranged on the opening 12, and the elastic snap hook 31 on the antenna cover 30 is directly snap-coupled with the snap protrusion 14 at the slot opening 13a of the water guide groove 13, so that the antenna cover 30 can be directly detached from the shell 10, without the need to first remove the upper shell and the lower shell and then remove the antenna cover 30 as in the prior art. This is beneficial for production line assembly and for later maintenance of the on-board antenna area 20a. In addition, although the snap coupling of the elastic snap hook 31 and the snap protrusion 14 in the water guide groove 13 narrows the slot opening 13a, the height of the water barrier 13c at the slot opening 13a can be increased as described above to ensure that the liquid flow at the slot opening 13a does not change (at least does not significantly decrease). By adjusting the fitting tolerance of the elastic snap hook 31 and the snap protrusion 14, the tightness of their snap coupling can be adjusted.

[0065] In combination Figure 8a and 8b As shown in Figs. 7 and 8, further, one of the outer wall 10a of the shell 10 and the antenna cover 30 is formed with a positioning hole or positioning groove 15, and the other is formed with a positioning protrusion 32, so that the positioning hole or positioning groove 15 is first combined with the positioning protrusion 32, and then the elastic snap hook 31 is snap-coupled with the snap protrusion 32.

[0066] In this embodiment, the antenna cover 30 is substantially in the shape of “]”, the upper portion thereof is formed with two positioning protrusions 32, the lower portion thereof is formed with one positioning protrusion 32, and the middle portion thereof is formed with the aforementioned elastic snap hook 31. Correspondingly, the outer wall 10a of the upper shell 10b is formed with two positioning holes or positioning grooves 15, and the outer wall 10a of the lower shell 10c is formed with one positioning hole or positioning groove 15.

[0067] In other embodiments, the antenna cover 30 is substantially in the shape of “]”, the upper portion thereof is formed with one positioning protrusion 32, the lower portion thereof is formed with two positioning protrusions 32, and the middle portion thereof is formed with the aforementioned elastic snap hook 31. Correspondingly, the outer wall 10a of the upper shell 10b is formed with one positioning hole or positioning groove 15, and the outer wall 10a of the lower shell 10c is formed with two positioning holes or positioning grooves 15.

[0068] In other embodiments, positioning protrusions 32 can be formed on the outer wall 10a of the upper housing 10b and the lower housing 10c, and positioning holes or positioning slots 15 can be formed on the antenna cover 30.

[0069] In the present embodiment, the middle part of the antenna cover 30 is irregularly shaped, and a plurality of auxiliary positioning features 33 are formed thereon, which can be protrusions, steps, hooks, etc. On the outer wall 10a of the housing 10, a plurality of matching auxiliary guiding features can be formed.

[0070] Those skilled in the art should understand that the positioning holes or positioning slots 15 and the positioning protrusions 32 can provide guidance for the combination of the antenna cover 30 and the housing 10, so that the elastic clamping hooks 31 can be smoothly clamped with the clamping protrusions 14 in the subsequent process. The antenna cover 30 can be more easily assembled directly on the housing 10 or directly removed from the housing 10, which is beneficial to the production line assembly and also beneficial to the later maintenance of the on-board antenna area 20a.

[0071] Further, the positioning protrusions 32 have rough surfaces so that they can be interference-fitted with the positioning holes or positioning slots 15.

[0072] And / or, the thickness of the tail of the positioning protrusions 32 is greater than the end, so that they can be interference-fitted with the positioning holes or positioning slots 15.

[0073] In the present embodiment, two positioning protrusions 32 are formed on the upper part of the antenna cover 30, which have rough surfaces (e.g. small particles are formed on the surfaces), and one positioning protrusion 32 is formed on the lower part of the antenna cover 30, which has a tail with a thickness greater than the end.

[0074] In other embodiments, all the positioning protrusions 32 have rough surfaces, or all the positioning protrusions 32 have tails with thicknesses greater than the ends.

[0075] Those skilled in the art should understand that whether the positioning protrusions 32 have rough surfaces or the tails of the positioning protrusions 32 have thicknesses greater than the ends, both can provide a damping feel in the clamping process of the antenna cover 30 and the housing 10. Moreover, when the domain controller 100 is installed on a vehicle, vibration is inevitable during the driving of the vehicle, and the positioning protrusions 32 in the above forms can prevent the antenna cover 30 from shaking, thereby enhancing the reliability of the domain controller 100.

[0076] Further, the housing 10 is protrusively formed with a water retaining wall 16 around the opening 12.

[0077] Those skilled in the art should understand that the water-blocking wall 16 can prevent liquid on the surface of the shell 10 from flowing to the side of the antenna cover 30 in advance, and avoid excessive liquid from the water guide groove 13.

[0078] Further, the circuit board 20 is provided with a connector 20b, and the shell 10 is provided with a connector mounting port 17 and a water-blocking wall 16 protruding around the connector mounting port 17.

[0079] Those skilled in the art should understand that the water-blocking wall 16 of the connector mounting port 17 is arranged on the side extending along the outer edge of the shell 10, which is similar to the structure of a hat brim, so that the connector 20b does not protrude from the shell 10, and the water-blocking wall 16 protrudes from the surface of the shell 10. The water-blocking wall 16 has the effect of preventing liquid from falling on the connector 20b, and can also prevent collision and stepping.

[0080] Further, the antenna cover 30 is provided with at least one type of reinforcing rib 34.

[0081] In this embodiment, the middle part of the antenna cover 30 in the shape of “]” has a plurality of hexagonal reinforcing ribs 34 arranged in a grid shape. The antenna cover 30 is also provided with a plurality of fish fin-shaped reinforcing ribs 34 connecting the upper part and the middle part, and triangular reinforcing ribs 34 connecting the lower part and the middle part.

[0082] Those skilled in the art should understand that the shape of the antenna cover 30 is not limited in the present application, as long as it can cover the opening 12. Therefore, one or more types of reinforcing ribs 34 can be arranged according to the specific shape of the antenna cover 30, so as to improve the structural strength of the antenna cover 30, reduce the deformation of the antenna cover 30 during installation and use, and better protect the circuit board 20 (especially the on-board antenna area 20b).

[0083] Further, the antenna cover 30 is not located at the top corner position of the shell 10.

[0084] Those skilled in the art should understand that based on the fact that the antenna cover 30 can be directly installed on the shell 10, and the position of the opening 12 on the shell 10 has a high degree of freedom, the antenna cover 30 of the present application is not located at the top corner position of the shell 10, thereby overcoming the defect that the antenna cover 30 is easy to break when falling or colliding in the prior art.

[0085] In addition, the domain controller described above can also be used in a movable platform. The movable platform can be a car, a UAV, a remote control vehicle, an unmanned ship or a robot, wherein the car can be a self-driving vehicle or a manned vehicle, and the UAV can be a drone or other UAV. Of course, the movable platform is not limited to the above-mentioned movable platforms, and can also be other movable platforms.

[0086] Those skilled in the art should understand that, since the movable platform adopts the domain controller described above, it has all the technical effects brought by the domain controller. For example, when liquid drops on the surface of the shell 10 or the surface of the antenna cover 30, part of the liquid seeps into the second accommodating cavity 11b from the gap between the antenna cover 30 and the outer wall 10a, and these liquids will not directly drop on the PCBA board, but will flow into the water guide groove 13, and finally be discharged out of the second accommodating cavity 11b through the slot 13a, thereby avoiding damage to the PCBA board and the antenna chip. The domain controller 100 can meet the waterproof requirement of IP5K2 level.
