Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular provides a vehicle and a controller thereof. Background Art

[0002] The controller on the vehicle is usually installed in the corner of the vehicle, and the controller is covered and hidden by the interior panel. During the daily use of the vehicle, the driver and passengers in the car may drop the water bottle and spill water inside the car when drinking water. The spilled water can easily drip onto the controller through the gaps in the interior panel. In order to reduce the possibility of water entering the controller and causing internal circuit short circuits, the controller shell usually adopts a sealed shell. Since the side panel of the controller is provided with a connector for connecting to the communication cable of the external device, the water dripping on the shell will flow around along the top of the shell. When the water flows to the side panel where the connector is provided, the water can easily enter the inside of the connector and cause a short circuit. In order to reduce the risk of water ingress and short circuit at the connector, an eaves structure is usually provided at the position where the connector is provided on the shell to prevent the spilled water from flowing onto the connector.

[0003] However, since the connectors need to be manually connected to external device cables, a certain amount of space is required for operation, and the installation of the eaves structure takes up a certain amount of space. For thinner controllers, the connectors occupy a large part of the side panel where they are located, and a certain amount of space is required to connect the connectors to the external device cables. In this case, installing the eaves structure will seriously reduce the operating space for connecting the connectors to the external devices.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problem, namely, to solve the problem that a controller in which the connector occupies most of the area of ​​the side panel and uses an eaves structure to waterproof the connector will affect the operating space for connecting the connector with external equipment.

[0006] In a first aspect, the present invention provides a controller for a vehicle, the controller comprising a shell, a first side panel of the shell being provided with a connector for communicating with an external device, a top panel of the shell being provided with an upwardly extending heat sink at a position away from the first side panel, the top of the heat sink being covered with a cover panel, a first drainage groove being formed on the top panel extending along a horizontal extension direction of the first side panel, a first extension panel being connected to an edge of the cover panel near the first side panel and extending obliquely downward toward the first side panel, a lower portion of the first extension panel abutting against a portion of the top panel between the first drainage groove and the first side panel, a drainage hole being formed on the first extension panel extending through the thickness direction thereof.

[0007] In the preferred technical solution of the above-mentioned controller, a plurality of the drain holes are formed on the first extension plate, and the plurality of drain holes are distributed on the first extension plate in at least two rows. The drain holes in each row are uniformly distributed in sequence along the horizontal extension direction of the first side plate, and the drain holes in two adjacent rows are staggered in the horizontal extension direction of the first side plate.

[0008] In a preferred technical solution of the above controller, the size of the water drop holes in the horizontal extension direction of the first side plate is not less than the size between adjacent edges of two adjacent water drop holes in the same row.

[0009] In the preferred technical solution of the above-mentioned controller, the lower part of the first extension plate includes a lower edge and a second extension plate extending horizontally from the lower edge toward the first side plate, and the lower surface of the second extension plate abuts against the part of the top plate located between the first drainage groove and the first side plate.

[0010] In a preferred technical solution of the above controller, the lower edge of the first extension plate extends downward to form a first drip rib, and the first drip rib is located above the first drainage groove.

[0011] In the preferred technical solution of the above-mentioned controller, a second drainage groove extending along the horizontal extension direction of the first side panel is formed on the top plate, and the second drainage groove is located on the top plate between the first drainage groove and the first side panel, and the upper part of the partition structure between the first drainage groove and the second drainage groove abuts against the lower surface of the second extension plate.

[0012] In a preferred technical solution of the above controller, a second drip rib is formed on the lower surface of the second extension plate, and the second drip rib is located above the second drainage groove.

[0013] In a preferred technical solution of the above controller, the upper surface of the second extension plate is an inclined surface that slopes downward from one end to the other end in the horizontal extension direction of the first side plate or a inclined surface that slopes downward from the middle to both ends.

[0014] In a preferred technical solution of the above controller, an inclined guide surface is formed between the side of the first drainage groove away from the first side plate and the upper surface of the top plate.

[0015] When adopting the above technical solution, the controller includes a shell, a first side panel of the shell is provided with a connector for communicating with an external device, an upward-extending heat sink is provided on the top plate of the shell away from the first side panel, the top of the heat sink is covered with a cover plate, a first drainage groove extending along the horizontal extension direction of the first side panel is formed on the top plate, a first extension plate extending obliquely downward toward the first side panel is connected to the edge of the cover plate near the first side panel, the lower part of the first extension plate abuts against the part of the top plate between the first drainage groove and the first side panel, and a drainage hole is formed on the first extension plate.

[0016] When water drips onto the housing cover, the water flowing toward the controller connector first flows through the first extension plate, then through the drain holes in the first extension plate and into the first drain trough. This reduces the risk of water flowing into the connector and causing a short circuit, effectively protecting the controller's safety. Furthermore, this eliminates the need for an eaves structure at the housing connector location to block spilled water from reaching the connector, eliminating the impact on the operating space for connecting the connector to external devices.

[0017] Preferably, a plurality of drain holes are formed on the first extension plate, and the plurality of drain holes are distributed on the first extension plate in at least two rows. The drain holes in each row are evenly distributed in sequence along the horizontal extension direction of the first side plate, and the drain holes in two adjacent rows are staggered in the horizontal extension direction of the first side plate.

[0018] Through such an arrangement, when water flows downward along the first extension plate, the water that flows through the upper row of drain holes but does not pass through the drain holes can continue to flow downward and flow through the next row of drain holes and drip into the first drain trough, so that the water can flow into the first drain trough more effectively, further reducing the risk of water flowing into the connector.

[0019] Preferably, the dimension of the water drop holes in the horizontal extension direction of the first side plate is not less than the dimension between adjacent edges of two adjacent water drop holes in the same row.

[0020] Through such an arrangement, the downspouts in the next row can better intercept the water that has flowed through the downspouts in the previous row but has not passed through, further reducing the risk of water flowing into the connector.

[0021] Preferably, the lower portion of the first extension plate includes a lower edge and a second extension plate extending horizontally from the lower edge toward the first side plate, and the lower surface of the second extension plate abuts against a portion of the top plate between the first drain groove and the first side plate.

[0022] Through such a setting, the contact area with the top plate of the shell can be increased, the sealing effect can be improved, and the risk of water on the first extension plate passing through the drain hole and flowing along the lower surface of the first extension plate to the lower part of the first extension plate and through the gap that may exist between the lower part of the first extension plate and the top plate of the shell to flow to the connector is reduced.

[0023] Preferably, the lower edge of the first extension plate extends downward to form a first drip rib, and the first drip rib is located above the first drainage groove.

[0024] Through such an arrangement, when a portion of the water passing through the drain hole flows along the lower surface of the first extension plate to the lower part of the first extension plate, the first drip rib can guide and enable this portion of water to drip more easily into the first drainage groove, further reducing the risk of this portion of water passing through the gap that may exist between the lower part of the first extension plate and the top plate of the shell and flowing to the connector.

[0025] Preferably, a second drainage groove extending along the horizontal extension direction of the first side plate is formed on the top plate, and the second drainage groove is located on the top plate between the first drainage groove and the first side plate, and the upper part of the partition structure between the first drainage groove and the second drainage groove abuts against the lower surface of the second extension plate.

[0026] With such an arrangement, even if a small amount of water passes through the gap between the second extension plate and the top plate and flows toward the first side plate, this part of the water can flow into the second drainage groove and be discharged through the second drainage groove, preventing this part of the water from continuing to flow toward the first side plate, further reducing the risk of water flowing to the connector.

[0027] Preferably, a second drip rib is formed on the lower surface of the second extension plate, and the second drip rib is located above the second drainage groove.

[0028] With this arrangement, when a small amount of water passes through the gap between the second extension plate and the top plate and flows toward the first side plate, the second drip rib can guide this portion of water to fall into the second drainage groove, further reducing the risk of water flowing into the connector.

[0029] Preferably, the upper surface of the second extension plate is an inclined surface that slopes downward from one end to the other end in the horizontal extension direction of the first side plate, or a inclined surface that slopes downward from the middle to both ends.

[0030] Through such an arrangement, when a portion of water on the upper surface of the first extension plate does not pass through the drain hole and flows onto the second extension plate, this portion of water can flow along the inclined surface on the upper surface of the second extension plate to the side plate position adjacent to the shell and the first side plate and flow down, thereby avoiding the situation where this portion of water flows to the first side plate and enters the connector.

[0031] Preferably, an inclined guide surface is formed between the side of the first drainage groove away from the first side plate and the upper surface of the top plate.

[0032] With such an arrangement, the water that passes through the drain hole and drips outside the first drain groove can be urged to flow into the first drain groove, thereby draining the water more effectively.

[0033] In a second aspect, the present invention further provides a vehicle, comprising the vehicle controller of any one of the above technical solutions.

[0034] It should be noted that the controller has all the technical effects of the vehicle controller described in any of the above technical solutions, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] First, those skilled in the art should understand that the embodiments described below are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0042] It should be noted that in the description of the invention, terms such as "front," "rear," "left," and "right" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and are not intended to indicate or imply that the device or component described must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the term "connection" should be understood in a broad sense. For example, it can refer to a fixed connection, a detachable connection, or an integral connection, and can be a direct connection or an indirect connection. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0044] Based on the problem mentioned in the background technology that the connector of the controller occupies most of the area of ​​the side panel where it is located and the use of an eaves structure to waterproof the connector will affect the operating space for connecting the connector with external equipment, the present invention provides a vehicle controller, the controller includes a shell, a first side panel of the shell is provided with a connector for communicating with an external device, an upwardly extending heat sink is provided on the top plate of the shell away from the first side panel, the top of the heat sink is covered with a cover plate, a first drainage groove extending along the horizontal extension direction of the first side panel is formed on the top plate, a first extension plate extending obliquely downward toward the first side panel is connected to the edge of the cover plate near the first side panel, the lower part of the first extension plate abuts against the part of the top plate between the first drainage groove and the first side panel, and a drainage hole is formed on the first extension plate.

[0045] When water drips onto the housing cover, the water flowing toward the controller connector first flows through the first extension plate, then through the drain holes in the first extension plate and into the first drain trough. This reduces the risk of water flowing into the connector and causing a short circuit, effectively protecting the controller's safety. Furthermore, this eliminates the need for an eaves structure at the housing connector location to block spilled water from reaching the connector, eliminating the impact on the operating space for connecting the connector to external devices.

[0046] Refer to the following Figures 1 to 3 The controller of the vehicle of the present invention is introduced. Figure 1 This is a schematic diagram of the structure of a vehicle controller according to an embodiment of the present invention. Figure 1 , Figure 2 yes Figure 1 The enlarged view of the part A in the middle, Figure 3 This is a schematic diagram of the structure of a vehicle controller according to an embodiment of the present invention. Figure 2.

[0047] like Figures 1 to 3 Shown and referenced Figure 3 In the orientation shown, the vehicle controller includes a housing 1, which includes a top plate 11 located at the top, a first side plate 12 located on the left, a second side plate 13 located at the front, a third side plate located on the right (not shown in the figure), a fourth side plate located at the rear (not shown in the figure), and a bottom plate located at the bottom (not shown in the figure). The top plate 11, the first side plate 12, the second side plate 13, the third side plate, the fourth side plate, and the bottom plate form a receiving cavity (not shown in the figure), which contains a circuit board (not shown in the figure). A connector 2 for connecting to a communication cable of an external device is provided on the first side plate 12, and one end of the connector 2 located inside the housing 1 is connected to the circuit board. An upward extending heat sink is provided on the top plate 11 at a position away from the first side plate 12. The heat sink is a plurality of fins 31 extending upward and distributed in parallel in the left and right directions. A cover plate 32 is covered on the top of all the fins 31. The adjacent fins 31, the cover plate 32 and the top plate 11 form an air duct 33 extending in the front-to-back direction. A fan (not shown in the figure) is provided at one end of the air duct near the rear side plate. The fan is used to drive air to flow through the air duct 33 so that the fins 31 can quickly dissipate heat.

[0048] The top plate 11 is formed with a first drainage groove 111 and a second drainage groove 112 extending along the horizontal extension direction of the first side plate 12 (i.e., the front-to-back direction). The first drainage groove 111 and the second drainage groove 112 are both located in the area between the position of the fin 31 on the top plate 11 and the left edge, and the first drainage groove 111 and the second drainage groove 112 are distributed in sequence from right to left. A partition structure 113 is formed between the first drainage groove 111 and the second drainage groove 112. An inclined guide surface 114 is formed between the side edge of the first drainage groove 111 away from the first side plate 12 (i.e., the right side) and the upper surface of the top plate 11. The bottoms of the first drainage groove 111 and the second drainage groove 112 are both inclined surfaces inclined downward from the middle toward both ends.

[0049] The left edge of the cover plate 32 is connected to a first extension plate 41 that extends obliquely downward toward the first side plate 12. A second extension plate 42 extends horizontally from the lower edge of the first extension plate 41 toward the first side plate 12. The upper surface of the second extension plate 42 is a slope that slopes downward from the center toward both ends. The lower surface of the second extension plate 42 abuts the top of the barrier structure 113. The second extension plate 42 covers a portion of the width of the first and second drainage channels 111 and 112. For example, the left and right edges of the second extension plate 42 are located in the middle of the openings of the second and first drainage channels 112, respectively. A first drip rib 421 extends downward from the lower edge of the first extension plate 41. The first drip rib 421 is a strip-shaped rib that extends in the front-to-back direction. A second drip rib 422 extends downward from the lower surface of the second extension plate 42, near its left edge. The second drip rib 422 is a strip-shaped rib that extends in the front-to-back direction. The first extension plate 41 is formed with a plurality of drainage holes 411. These drainage holes 411 are arranged in two rows. The drainage holes 411 in each row are evenly spaced in the front-to-back direction, with the drainage holes 411 in the lower row alternating with the drainage holes 411 in the upper row. The drainage holes 411 are waist-shaped, and their dimension in the front-to-back direction is greater than the dimension between the adjacent edges of two adjacent drainage holes 411 in the same row.

[0050] When water drips onto the housing cover 32, some of the water will flow toward the connector 2. This water will first flow onto the first extension plate 41. Under the action of gravity, the water on the first extension plate 41 will flow downwardly along the upper surface of the first extension plate 41. Some of the water will flow through the upper row of drop holes 411 and then pass through the upper row of drop holes 411. Water flowing between two adjacent drop holes 411 in the upper row cannot pass through the upper row of drop holes 411 and then continues to flow downwardly along the upper surface of the first extension plate 41. This water will flow through the lower row of drop holes 411 and then pass through the lower row of drop holes 411.

[0051] A portion of the water that passes through the drop hole 411 drips directly onto the inclined guide surface 114 and flows into the first drain trough 111. Another portion of the water that passes through the drop hole 411 flows downward along the lower surface of the first extension plate 41 to the lower edge of the first extension plate 41, and then drips into the first drain trough 111 under the guidance of the first drip rib 421. The water that enters the first drain trough 111 flows along the inclined surface of the trough bottom toward the two ends of the first drain trough 111 and is finally discharged from both ends of the first drain trough 111.

[0052] When a large amount of water flows along the upper surface of the first extension plate 41, some water will not pass through the upper and lower rows of drain holes 411 after flowing through the drain holes 411. This water will continue to flow downward along the upper surface of the first extension plate 41 and finally flow to the left side of the second extension plate 42. Part of this water will flow directly downward from the left side of the second extension plate 42 into the second drain groove 112, while the other part will drip downward along the second drip rib 422 at the left side of the second extension plate 42 into the second drain groove 112. The water entering the second drain groove 112 will flow along the inclined surface of the groove bottom toward the two ends of the second drain groove 112 and finally be discharged from the two ends of the second drain groove 112.

[0053] This arrangement reduces the risk of water flowing into the connector and causing a short circuit, effectively protecting the controller's safety. Furthermore, it eliminates the need for an eaves structure at the connector housing to block spilled water, eliminating the impact on the operating space for connecting the connector to external device cables.

[0054] It should be noted that the front-to-back dimension of the drain holes 411 is greater than the dimension between the adjacent edges of two adjacent drain holes 411 in the same row. This is merely a preferred arrangement and can be adjusted in practice. For example, the front-to-back dimension of the drain holes 411 can be equal to the dimension between the adjacent edges of two adjacent drain holes 411 in the same row, or the front-to-back dimension of the drain holes 411 can be smaller than the dimension between the adjacent edges of two adjacent drain holes 411 in the same row. Furthermore, the drain holes 411 are waist-shaped, but this is merely a specific arrangement and can be adjusted in practice. For example, the drain holes 411 can be elliptical, rectangular, or other shapes. Furthermore, the multiple drain holes 411 are arranged in two rows on the first extension plate 41. This is merely a specific arrangement and can be adjusted in practice. For example, the multiple drain holes 411 can be arranged in three, four, or more rows on the first extension plate 41.

[0055] It should also be noted that the upper surface of the second extension plate 42 is a sloped surface that slopes downward from the center toward both ends. This is merely a preferred configuration and can be adjusted in practice. For example, the upper surface of the second extension plate 42 can be a sloped surface that slopes downward from one end toward the other, or the upper surface of the second extension plate 42 can be configured as a horizontal surface. Furthermore, the bottoms of the first and second drainage grooves 111, 112 are both sloped surfaces that slope downward from the center toward both ends. This is also a preferred configuration and can be adjusted in practice. For example, the bottoms of the first and second drainage grooves 111, 112 can be sloped surfaces that slope downward from one end toward the other, or the bottoms of the first and second drainage grooves 111, 112 can be horizontal surfaces. Furthermore, the first and second drip ribs 421, 422 are both strip-shaped ribs that extend in the front-to-back direction. This is merely a specific configuration and can be adjusted in practice. For example, the first and second drip ribs 421, 422 can be configured as multiple columnar ribs.

[0056] In another feasible embodiment, different from the above embodiment, the first drip rib 421 and / or the second drip rib 422 of the above embodiment are not included.

[0057] In another feasible embodiment, different from the above embodiment, the lower surface of the left edge of the second extension plate 42 abuts against the portion of the top plate 11 located on the left side of the second drainage groove 112, and the second drip rib 422 extends downward on the lower surface of the second extension plate 42 and is located above the second drainage groove 112.

[0058] In another feasible embodiment, different from the above embodiment, the second drainage groove 112 and the second drip rib 422 of the above embodiment are not included, and the lower surface of the second extension plate 42 abuts against the portion of the top plate 11 located on the left side of the first drainage groove 111.

[0059] In another feasible embodiment, different from the above embodiment, the second drainage groove 112, the second extension plate 42, the first drip rib 421 and the second drip rib 422 of the above embodiment are not included, and the lower edge of the first extension plate 41 directly abuts against the portion of the top plate 11 located on the left side of the first drainage groove 111.

[0060] In addition, the present invention also provides a vehicle, which includes the controller in any of the above embodiments. It should be noted that the vehicle can be an electric vehicle, a fuel vehicle, or a hybrid vehicle.

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. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
