[0002] The present invention relates to the technical field of controllers, and in particular provides a controller and a vehicle. Background Art

[0003] With the continuous advancement of technology, electric-powered new energy vehicles have become a major segment of the family car market. The controller is a key component in these vehicles, connecting them to the vehicle's drive system, battery management system, and cabin system. To reduce communication lines, controllers are typically equipped with antennas to transmit and receive information, enabling communication between the controller and other devices.

[0004] Onboard antennas are commonly used in controllers due to their low cost. The controller housing has a via for the onboard antenna to pass through. One end of the onboard antenna is connected to the circuit board inside the controller housing, and the other end of the onboard antenna passes through the via in the housing.

[0005] However, in many usage scenarios, water can easily drip onto the controller and cause the onboard antenna vias to enter the controller, leading to circuit board failure. For example, condensation from a vehicle's air conditioner during operation could leak onto the controller, or condensation from the inner walls of other devices using the controller could drip onto the controller due to humid weather.

[0006] Therefore, this field needs a new technical solution to solve the above problems.

[0007] Summary of the Invention

[0008] The present invention aims to solve the above technical problem, namely, to solve the problem that the circuit board of the existing controller is easily damaged by dripping water entering through the via hole of the onboard antenna.

[0009] In a first aspect, the present invention provides a controller, comprising a shell, a circuit board being arranged in the shell, an onboard antenna being connected to the circuit board, a top plate of the shell being provided with a through hole for the onboard antenna to pass through, a portion of the onboard antenna passing through the through hole, a water-blocking structure being provided on the top plate around the through hole, a protective cover being provided on the upper end cover of the onboard antenna, the projection of the protective cover on the top plate in the vertical direction covering the through hole and the water-blocking structure.

[0010] In a preferred technical solution of the above controller, the water-blocking structure includes water-blocking ribs arranged on the upper surface of the top plate around the periphery of the through hole.

[0011] In a preferred technical solution of the above controller, the water retaining rib is an annular water retaining rib sleeved around the periphery of the through hole.

[0012] In a preferred technical solution of the controller, there are multiple annular water retaining ribs, and the multiple annular water retaining ribs are sequentially spaced and arranged with the through hole as the center.

[0013] In a preferred technical solution of the above controller, the water-blocking structure includes an inclined ring plate structure formed on the top plate around the through hole, and the inclined ring plate structure is inclined downward in a radial direction away from the through hole.

[0014] In the preferred technical solution of the above controller, the protective cover includes a cap structure and an annular brim structure, the cap structure is provided on the upper end of the onboard antenna, and the annular brim structure is connected to the cap.

[0015] In the preferred technical solution of the above-mentioned controller, the upper surface of the annular brim structure is provided with an annular rib around the cap structure, the annular rib is provided with a notch, and the top plate is inclined downward in the direction away from the notch on the side of the notch away from the cap structure.

[0016] In a preferred technical solution of the above controller, the annular brim structure is inclined downward along the cap structure toward the notch.

[0017] In the preferred technical solution of the above-mentioned controller, a portion of the cap structure is located below the annular brim structure, a first clipping structure is provided on the outer wall of the portion of the cap structure located below the annular brim structure, and a second clipping structure is provided at the edge of the through hole and the area opposite to the through hole, and the first clipping structure is clip-connected to the second clipping structure.

[0018] When adopting the above technical solution, the controller includes a shell, a circuit board is arranged in the shell, an on-board antenna is connected to the circuit board, the top plate of the shell is provided with a through hole for the on-board antenna to pass through, a part of the on-board antenna passes through the through hole, the top plate is provided with a water-blocking structure on the periphery of the through hole, the upper end cover of the on-board antenna is provided with a protective cover, and the projection of the protective cover on the top plate in the vertical direction covers the through hole and the water-blocking structure.

[0019] During use, when water droplets drip from above the controller, water droplets directly above the vias drip downward and land on the protective cover. The water droplets dripping on the protective cover further drip onto the area of ​​the controller's top plate outside the water-blocking structure. Water droplets not directly above the vias drip downward and land directly on the area of ​​the controller's top plate outside the water-blocking structure. The water-blocking structure prevents water dripping onto the area of ​​the controller's top plate outside the water-blocking structure from flowing toward the vias. This arrangement prevents the controller from malfunctioning due to dripping water entering through the vias of the onboard antenna, thus ensuring normal operation of the controller.

[0020] Preferably, the water-blocking structure includes water-blocking ribs arranged on the upper surface of the top plate around the periphery of the through hole.

[0021] This arrangement facilitates the arrangement of the water-blocking structure, reduces manufacturing difficulty, and reduces manufacturing costs.

[0022] Preferably, the water retaining rib is an annular water retaining rib sleeved on the periphery of the through hole.

[0023] Compared with a plurality of arc-shaped water-blocking ribs arranged around the edges of the via hole, this arrangement further simplifies the water-blocking structure, reduces manufacturing difficulty, and enhances the water-blocking effect of the water-blocking structure.

[0024] Preferably, there are multiple annular water retaining ribs, and the multiple annular water retaining ribs are sequentially spaced and sleeved around the through hole.

[0025] Through such a setting, it is possible to prevent water dripping onto the top plate of the controller in the area outside the water-blocking structure from flowing into the via hole, and to reduce the risk of water droplets first dripping onto the area outside the water-blocking structure on the top plate of the controller and then splashing into the area between the outer edge of the water-blocking structure and the via hole before flowing into the via hole, thereby further enhancing the water-blocking effect of the water-blocking structure and reducing the risk of water entering the interior of the controller through the via hole.

[0026] Preferably, the water-blocking structure includes an inclined ring plate structure formed on the top plate around the through hole, and the inclined ring plate structure is inclined downward in a radial direction away from the through hole.

[0027] This arrangement increases the difficulty of water dripping onto the top plate of the controller in the area outside the water-blocking structure to flow toward the vias, thereby reducing the risk of water dripping onto the top plate of the controller flowing into the vias.

[0028] Preferably, the protective cover includes a cap structure and an annular brim structure, the cap structure is provided on the upper end of the onboard antenna, and the annular brim structure is connected to the cap.

[0029] Through such an arrangement, compared with the method of "arranging the protective cover to include only the cap structure", the material used in manufacturing the protective cover is reduced while ensuring the same large shielding range.

[0030] Preferably, the upper surface of the annular brim structure is provided with an annular rib around the cap structure, the annular rib is provided with a notch, and the top plate is inclined downward in a direction away from the notch at a side of the notch away from the cap structure.

[0031] Through such a setting, water dripping on the protective cover can fall on the area on the top plate of the controller corresponding to the notch on the annular rib, and it is beneficial for this part of water to flow down from the top plate of the controller quickly, avoiding the increased risk of water gathering on the top plate and flowing into the via.

[0032] Preferably, the annular brim structure is inclined downward along the cap structure toward the notch.

[0033] Through such a setting, water droplets dripping on the protective cover can flow down more smoothly through the notch on the annular rib and fall on the area on the top plate of the controller corresponding to the notch on the annular rib, which is conducive to the dripping and drainage of water and further reduces the risk of water entering the via hole of the on-board antenna.

[0034] Preferably, a portion of the cap structure is located below the annular brim structure, a first clipping structure is provided on the outer wall of the portion of the cap structure located below the annular brim structure, a second clipping structure is provided at the edge of the through hole and the area opposite to the through hole, and the first clipping structure is clip-connected to the second clipping structure.

[0035] This arrangement improves the stability of the protective cover and reduces the risk of the onboard antenna being bent or damaged due to collisions.

[0036] In a second aspect, the present invention further provides a vehicle, comprising the controller according to any one of the above technical solutions.

[0037] It should be noted that the vehicle has all the technical effects of the controller described in any of the above technical solutions, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The provision of a protective cover and a water-blocking structure prevents the controller from malfunctioning due to dripping water entering through the vias of the onboard antenna, thereby ensuring the normal use of the controller.

The air duct enclosure 3 includes side panels 31 extending along the upper, left, and lower edges of the front panel 11, and a cover 32 secured to the front edge of the side panels 31. The side panels 31 and cover 32, together with the front panel 11 of the housing 1, form a cooling duct 4. An air inlet 41 communicating with the cooling duct 4 is provided on the left side of the side panel 31. The right end of the side panel 31, the right end of the front panel 11, and the right end of the cover 32 form an air outlet 42 communicating with the cooling duct 4. A cooling fan (not shown) is provided within the cooling duct 4 near the air inlet 41. A heat sink 43 extending horizontally is provided to the right of the cooling fan within the cooling duct 4. A connector 161 is provided on the bottom panel 16, extending through the interior and exterior of the housing 1. The first end of the connector 161 is located within the housing 1 and connected to the circuit board 2. The second end of the connector 161 is located outside the housing 1 and has multiple interfaces. The front panel 11, left panel 13, right panel 14, top panel 15, bottom panel 16, side panels 31, and heat sink 43 are integrally formed, and the rear panel 12 is fixed to the front panel 11 by screws. It should be noted that "front" refers to the direction perpendicular to the paper toward the reader in the state of Figure 2, and "rear" refers to the direction perpendicular to the paper away from the reader in the state of Figure 2.

[0054] As shown in Figures 1 to 7, three vias 151 are distributed along the left and right sides of the top plate 15 near the rear edge. A U-shaped water retaining rib 152 is provided on the upper surface of the top plate 15, serving as a water-blocking structure, around the periphery of each via 151. The U-shaped water retaining rib 152 surrounds the left side, front side, and rear side of the corresponding via 151. Three onboard antennas 21 are connected to the upper side of the circuit board 2, and the upper ends of the three onboard antennas 21 extend through the three vias 151, respectively. A protective cover 5 is provided over the upper end of each onboard antenna 21, and the projection of the protective cover 5 on the top plate 15 in the vertical direction covers the corresponding via 151 and water retaining rib 152. The protective cover 5 includes a cap structure 51 and an annular brim structure 52. The inner edge of the annular brim structure 52 is connected to the middle of the cap structure 51. The upper surface of the annular brim structure 52 is provided with an annular rib 53 around the cap structure 51 at a position close to the outer edge. Three notches 531 are provided on the front portion of the annular rib 53. The annular brim structure 52 is tilted downward from the back to the front as a whole. The top plate 15 and the portion of the side plate 31 flush with the top plate 15 are tilted downward from the back to the front as a whole. A first clamping structure is provided on the outer wall of the portion of the cap structure 51 located below the annular brim structure 52. A second clamping structure is provided on the edge of the through hole 151 and the area directly opposite the through hole 151. The first clamping structure and the second clamping structure are clamped and connected. Specifically, as shown in Figure 4, an annular first rib 54 and an annular second rib 55 are provided on the outer wall of the part of the cap structure 51 located below the annular brim structure 52. The annular first rib 54 and the annular second rib 55 are distributed in sequence from top to bottom. An annular slot 56 serving as a first clamping structure is formed between the annular first rib 54 and the annular second rib 55. A U-shaped clamping block 153 is provided at the edge of the through hole 151 and the area facing the through hole 151. A flange facing the opening of the U-shaped clamping block 153 is formed on the upper edge of the rear side plate 12. The U-shaped clamping block 153 and the flange on the upper edge of the rear side plate 12 are clamped into the slot 56 as a second clamping structure to achieve a fixed connection between the cap structure 51 and the shell 1.

[0055] During use, when water droplets drip from the top of the controller, the water droplets located directly above the through-hole 151 drip downward and fall exactly on the cap structure 51 or the annular brim structure 52 of the protective cover 5. The water droplets dripping on the cap structure 51 slide down onto the annular brim structure 52 under the action of gravity. Since the upper surface of the annular brim structure 52 is provided with an annular rib 53 around the cap structure 51 at a position close to the outer edge, and three notches 531 are provided on the front part of the annular rib 53, and the annular brim structure 52 is arranged downwardly in an overall direction from back to front, the water on the annular brim structure 52 will flow down through the three notches 531 on the annular rib 53 and drip onto the area on the top plate 15 that is located outside the water retaining rib 152 and in front of the three notches 531. Water droplets that are not directly above the through-hole drip downward and fall directly onto the area on the top plate 15 that is located outside the water retaining rib 152. Since the top plate 15 and the part of the side plate 31 flush with the top plate 15 are arranged to be tilted downward from the back to the front as a whole, water dripping on the top plate 15 in the area outside the water retaining rib 152 will flow quickly toward the front of the top plate 15 and finally flow down along the outer surface of the cover plate 32, avoiding the risk of water dripping on the top plate 15 gathering on the top plate 15 and increasing the risk of flowing into the through hole 151.

[0056] The above-mentioned structure prevents the controller from malfunctioning due to dripping water droplets entering through the via 151 of the onboard antenna 21, thereby ensuring the normal use of the controller. In addition, the water dripping on the top plate 15 flows toward the front of the top plate 15 and finally flows down along the outer surface of the cover plate 32. In this way, this part of the water can also be used to cool the air duct enclosure 3, thereby improving the heat dissipation effect of the heat dissipation duct 4, and further improving the heat dissipation effect of the circuit board 2 in the controller. Preferably, a plurality of deceleration ribs 321 are provided on the outer surface of the cover plate 32. By providing a plurality of deceleration ribs 321, the flow time of water on the outer surface of the cover plate 32 can be extended, thereby improving the heat dissipation effect of this part of the water on the heat dissipation duct 4, and further improving the heat dissipation effect of the circuit board 2 in the controller.

[0057] An annular rib 53 is provided on the upper surface of the annular brim structure 52 around the cap structure 51 at a position close to the outer edge, and three notches 531 are provided on the front part of the annular rib 53. The top plate 15 and the part of the side plate 31 flush with the top plate 15 are tilted downward from the back to the front as a whole, so that water dripping on the protective cover 5 can fall on the area on the top plate 15 corresponding to the notch 531 on the annular rib 53, and it is beneficial for this part of the water to flow down from the top plate 15 quickly, avoiding the increased risk of water gathering on the top plate 15 and flowing into the through hole 151.

[0058] Three notches 531 are provided on the front side of the annular rib 53, and the annular brim structure 52 is tilted downward from the back to the front as a whole, so that water droplets dripping on the protective cover 5 can flow down more smoothly through the notches 531 on the annular rib 53 and fall on the area on the top plate 15 corresponding to the notches 531 on the annular rib 53, which is conducive to the dripping and drainage of water, and further reduces the risk of water entering the through hole 151 of the on-board antenna 21.

[0059] The second clamping structure and the arrangement of the second clamping structure improve the stability of the protective cover 5 and can reduce the risk of the onboard antenna 21 being bent or damaged due to collision.

[0060] It should be noted that a block 153 is provided at the edge of the through hole 151 and the area directly opposite to the through hole 151, and a slot 56 is provided on the outer wall of the portion of the cap structure 51 located below the annular brim structure 52. This is only a specific arrangement, and adjustments can be made to it in actual applications, such as a slot is provided at the edge of the through hole 151 and the area directly opposite to the through hole 151, and a block is provided on the outer wall of the portion of the cap structure 51 located below the annular brim structure 52. In addition, three notches 531 are provided on the front portion of the annular rib 53, and the annular brim structure 52 is tilted downward from the back to the front as a whole. This is only a preferred arrangement, and adjustments can be made to it in actual applications, such as the annular brim structure 52 is arranged horizontally as a whole, and one, two, four or more notches are provided on the front portion of the annular rib 53, or the annular rib 53 is evenly distributed with multiple notches. When annular rib 53 is evenly distributed with multiple notches, top plate 15 is preferably configured so that the portion of each notch located away from cap structure 51 is tilted downward, away from the corresponding notch. Furthermore, top plate 15 is provided with three vias 151, and circuit board 2 is connected to three onboard antennas 21. This is merely a specific configuration and can be adjusted in practice, such as to have one, two, four, or more vias 151 and onboard antennas 21.

[0061] In another feasible embodiment, different from the above embodiment, the through hole 151 is provided in a non-edge area of ​​the top plate 15, that is, there are parts of the top plate 15 around the through hole 151, the block 153 is an annular block formed in the area of ​​the edge of the through hole 151 directly opposite the through hole 151, the annular block is inserted into the annular slot 56, and the water retaining rib 152 is provided as an annular water retaining rib that is sleeved on the periphery of the through hole 151. By such a setting, the gap between the onboard antenna 21 and the through hole 151 can be further eliminated, and the risk of water dripping on the top plate 15 splashing and entering the housing 1 through the through hole 151 can be further reduced. Preferably, there are multiple annular water retaining ribs, and the multiple annular water retaining ribs are sleeved in sequence with the through hole 151 as the center. This can not only prevent water dripping onto the top plate 15 in the area outside the annular water retaining rib from flowing toward the through hole 151, but also reduce the risk of water droplets that first drip onto the top plate 15 in the area outside the annular water retaining rib and then splash into the area between the outer edge of the annular water retaining rib and the through hole 151 before flowing into the through hole 151, further enhancing the water-blocking effect of the annular water retaining rib and reducing the risk of water entering the controller through the through hole 151.

[0062] In another feasible embodiment, different from the above embodiment, no annular rib is provided. Furthermore, the annular brim structure 52 may also not be provided.

[0063] In some other feasible embodiments, different from the above embodiments, the first clamping structure and the second clamping structure are not provided, and the protective cover 5 is only sleeved on the upper end of the onboard antenna 21 through the cap structure 51 .

[0064] In some other feasible embodiments, different from the above embodiments, no water retaining rib 152 is provided, but at least the portion of the top plate 15 adjacent to the periphery of the through hole 151 is provided as an inclined ring plate structure surrounding the through hole 151, and the inclined ring plate structure is inclined downward in the radial direction away from the through hole 151, and the inclined ring plate structure serves as a water blocking structure.

[0065] In some other feasible embodiments, different from the above embodiments, at least the portion of the top plate 15 adjacent to the periphery of the through hole 151 is configured as an inclined ring plate structure surrounding the through hole 151, and the inclined ring plate structure is inclined downward in the radial direction away from the through hole 151, and the water retaining ribs and the inclined ring plate structure together constitute a water-blocking structure.

[0066] In addition, the present invention also provides a vehicle, which includes the controller in any one of the above embodiments.

[0067] It should be noted that the controller of the present invention can be applied not only to vehicles, but also to other equipment requiring a controller.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
