Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of vehicle accessories, in particular, to a water-blocking plug, a controller and a vehicle. BACKGROUND

[0002] Currently, some automobile controllers have gradually increasing heat generation, and because the use environment of the controller is relatively harsh, the protection level of the controller also has high requirements. The controller shell not only needs to have excellent waterproof sealing performance, but also needs to have the ability to balance the pressure difference between the inside and outside of the controller.

[0003] In related technologies, a vent hole is arranged on the controller shell, in order to ensure the protection performance of the vent hole and balance the pressure difference between the inside and outside of the controller, so as to effectively prevent the vent hole from being damaged due to high air pressure. A waterproof and breathable valve or a waterproof and breathable film and other waterproof and breathable structures are usually arranged at the position corresponding to the vent hole. The conventional waterproof and breathable structure is usually installed outside the vehicle. For example, when the waterproof and breathable structure is washed by a high-pressure water gun, if the waterproof and breathable structure is not reliably protected, the waterproof and breathable structure is easily damaged and water enters the controller shell. The current more common technical solution is to shield the waterproof and breathable structure by a simple shielding structure, so as to avoid the high-pressure water directly acting on the surface of the waterproof and breathable structure. Although this design reduces the water pressure acting on the surface of the waterproof and breathable structure and the vent hole, the water pressure directly acting on the surface of the vent hole still has a certain pressure, which still has the risk of damaging the membrane.

DETAILED DESCRIPTION

[0029] The specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0030] In the present disclosure, the orientation words such as "inner" and "outer" are used in relation to the contour of the respective component itself, unless otherwise stated. The terms such as "first", "second" and the like used in the present disclosure are used to distinguish one element from another, and do not have sequential or important meanings. In addition, the following description, when referring to the drawings, the same reference numerals in different drawings represent the same or similar elements.

[0031] Referring to Figures 1-4 , the present disclosure provides a water-blocking plug cover 10 which can include a body 1 configured as a plate-shaped structure to form a sheltering effect while not occupying too much space. One side of the body 1 in the thickness direction can be formed with a groove 2, and the thickness direction mentioned hereinafter can refer to the direction indicated by the Z arrow in Figure 4 , a protrusion 3 can be arranged in the groove 2 to form a composite flow channel 4 on the body 1. By forming the composite flow channel 4 directly on the body 1, not only is the space of the water-blocking plug cover 10 itself used efficiently, but also the external space required for additional flow channels is avoided, greatly improving the overall space utilization of the component. The composite flow channel 4 can have an inlet end 43 and a closed end 44. The inlet end 43 can be arranged at the edge of the body 1, so that when the water-blocking plug cover 10 is installed at a predetermined position, it can meet the need for ventilation, for example, when the water-blocking plug cover of the present disclosure is installed on the controller housing 8 mentioned below, it can not only play a protective role, but also ensure the ventilation of the ventilation hole 81. The inlet end 43 can be arranged at the edge of one side of the body 1 in the length direction, where the length direction can refer to the direction indicated by the X arrow in Figure 4 , when the fluid is high-pressure washing water impacting in the thickness direction of the body 1, this arrangement can effectively ensure the blocking effect of the water-blocking plug cover 10 on the fluid. The closed end 44 can be located on the opposite side of the composite flow channel 4 from the inlet end 43 in the flow direction, so as to effectively lengthen the flow path of the fluid in the composite flow channel 4 and improve the effect of reducing the speed of the fluid, as shown in Figure 1 , the closed end 44 can be arranged at one side of the body 1 in the thickness direction, so that an effective gap can be formed between the body 1 and the predetermined installation position to ensure the ventilation effect between them. The position of the composite flow channel 4 near the closed end 44 can also have at least one flow convergence position 5, and the flow convergence position 5 can be designed to make the fluids flowing from different directions through the flow convergence position 5 collide with each other to slow down. When the fluid enters the composite flow channel 4 through the inlet end 43 to flow to the closed end 44, the high-pressure washing water must pass through the flow convergence position 5, thereby effectively reducing the kinetic energy of the fluid when it reaches the closed end 44.

[0032] By the above technical scheme, the confluence position 5 and the composite flow channel 4 with the inlet end 43 and the closed end 44 are arranged on the body 1, so that the fluid flowing from the inlet end 43 to the closed end 44 must pass through the confluence position 5, thereby realizing that the fluids flowing in different directions to the closed end 44 can impact each other near the closed end 44, and the kinetic energy of the fluid flowing to the closed end 44 is maximally reduced.

[0033] With reference to Figure 1 , Figure 2 and Figure 4 , the protrusion 3 can include a first protrusion 31 arranged in the groove 2, and the first protrusion 31 can be used to divide the fluid from the inlet end 43 into the first flow channel 41 and the second flow channel 42. By reasonably arranging the arrangement position of the first protrusion 31, the fluid can be dispersed into different paths in time, thereby realizing the adjustment and control of the flow and the flow rate, and reducing the local pressure in the composite flow channel 4. The confluence position 5 can include a first confluence position 51 located at the end of the first flow channel 41 and the second flow channel 42, so that the fluid at the end of the first flow channel 41 and the second flow channel 42 can be decelerated by mutual impact during the flow process, thereby effectively reducing the impact force of the fluid when reaching the closed end 44.

[0034] Further, with reference to Figure 1 and Figure 2 , the first protrusion 31 can have a first corner 311 and a second corner 312 protruding outward. The first corner 311 can protrude in the reverse flow direction. When the fluid flowing in the forward direction impacts on the first corner 311, the flow direction of the fluid is forced to change, and then the fluid is divided into the first flow channel 41 and the second flow channel 42. At the same time, since the fluid needs to overcome the resistance to the first corner 311 to continue to flow in the reverse direction, the fluid is dispersed and part of the kinetic energy is reduced, thereby reducing the flow rate of the fluid. The second corner 312 can be located corresponding to the first confluence position 51. Specifically, the first protrusion 31 in the present disclosure utilizes the principle of Tesla valve, relies on the first corner 311 to generate a reverse resistance in the process of fluid flow, so that the fluid flowing downstream is divided to reduce the flow rate, and continues to flow downstream in different directions in the first flow channel 41 and the second flow channel 42, respectively. The fluid at the end of the first flow channel 41 and the second flow channel 42 will impact each other at the first confluence position 51. During the impact process, the motion direction and speed distribution of the fluid at the end of the first flow channel 41 and the second flow channel 42 will change, and energy is consumed, thereby realizing the reduction of the overall flow rate. It should be noted that the forward flow direction in the present disclosure refers to the arrow direction shown in Figure 1 , and the reverse flow direction is opposite.

[0035] As shown in Figure 1As shown, the outer contour of the first protrusion 31 can be configured as a hexagonal structure. With such design, the vertices of the hexagonal structure can be used for flow confluence or flow separation. When used for flow separation, the uniformity of flow separation of fluid when flowing through the first protrusion 31 can be effectively improved, thereby reducing the branch fluid flow and kinetic energy; when used for flow confluence, the mutual collision of fluid from different directions can be further promoted for energy dissipation, thereby enhancing the fluid pressure reduction effect. In addition, the fluid can flow along the edges of the hexagonal structure during the flow process, thereby improving the stability of the fluid flow process.

[0036] With reference to Figure 1 and Figure 2 , the protrusion 3 can further include a second protrusion 32. The first flow channel 41 and the second flow channel 42 can be respectively provided with the second protrusion 32, and the first flow channel 41 and the second flow channel 42 can each have a main path 403, so that the main path 403 is divided into a first branch path 401 and a second branch path 402 by the second protrusion 32 to further separate the fluid, thereby further reducing the fluid velocity and improving the effect of reducing the fluid impact force. The confluence position further includes a second confluence position 52 located at the end of the first branch path 401 and the second branch path 402, so as to enable the fluid to be subjected to secondary opposite impact deceleration, thereby further reducing the pressure and speed of the fluid flowing downstream.

[0037] Further, with reference to Figure 1 and Figure 2 , the second protrusion 32 can have a third corner 321, a fourth corner 322 and a fifth corner 323. The third corner 321 can protrude in the opposite flow direction, and the fourth corner 322 can protrude in the flow direction. The third corner 321 can separate the fluid from the main path 403 into the first branch path 401 and the second branch path 402, and the fourth corner 322 can be located corresponding to the second confluence position 52. The third corner 321 and the fourth corner 322 also use the Tesla valve principle to control the flow separation and speed reduction of the fluid, as described above, and will not be described again. As Figure 2As shown, the inner wall of the groove 2 and the second protrusion 32 define the second branch 402 as a hanging ear, that is, the fifth corner 323 can protrude towards the second branch 402, so that the fluid in the second branch 402 has a large bending angle during flow, so that the fluid is deflected and slowed down when passing through the fifth corner 323, and at the same time, the flow path of the second branch 402 is effectively lengthened, the residence time of the fluid in the second branch 402 is increased, and the fluid kinetic energy is greatly reduced. The position where the second branch 402 flows into the first branch 401 is the second confluence position 52, that is, the fourth corner 322 can be correspondingly arranged at the second confluence position 52, so that the fluid in the second branch 402 can be slowed down after being deflected, and when flowing through the second confluence position 52 along the fourth corner 322, it can be slowed down by colliding with the fluid in the first branch 401, so as to meet the requirement of reducing the fluid kinetic energy at the closed end 44.

[0038] With reference to Figure 1 , Figure 2 and Figure 4 , the water-blocking plug can further include a sealing sheet 6 which is in contact with the side wall of the groove 2 in the thickness direction and can protrude from the body 1 in the thickness direction. In the embodiments provided in the present disclosure, the water-blocking plug can be mounted on the control housing 8 mentioned below, and by designing the sealing sheet 6 to protrude laterally from the body 1, the sealing sheet 6 can abut against the controller housing 8 when the water-blocking plug is mounted on the controller housing 8, and be tightly clamped between the body 1 and the controller housing 8, so as to effectively increase the friction coefficient between the composite flow channel 4 and the controller housing 8, thereby ensuring the sealing effect between the composite flow channel 4 and the controller housing 8 through the sealing sheet 6, greatly reducing the risk of fluid leakage. According to the embodiments provided in the present disclosure, the sealing sheet 6 can be made of soft rubber material, so that the sealing sheet 6 has good elasticity and flexibility, so as to effectively fill the small gap formed between the composite flow channel 4 and the controller housing 8, thereby further ensuring the sealing performance. In the embodiments provided in the present disclosure, the extension length of the sealing sheet 6 can match the extension length of the composite flow channel 4, thereby improving the overall sealing.

[0039] In the embodiments provided in the present disclosure, the body 1 can be made of hard plastic material, so that the body 1 has good corrosion resistance, water resistance and electrical insulation, which can effectively prolong the service life of the water-blocking plug and ensure the safety of the controller. By making the body 1 of hard plastic, the overall quality of the water-blocking plug 10 is lighter, which meets the lightweight design principle. In addition, since hard plastic is easy to process and shape, the body 1 can be designed in various shapes and sizes according to actual needs.

[0040] With reference to Figure 3 and Figure 4The second aspect of the present disclosure provides a controller, which can include a controller housing 8, a gas permeable hole 81, a gas permeable film 82, and the water-blocking plug 10 provided by the present disclosure. The gas permeable hole 81 can be formed on the controller housing 8, and the gas permeable film 82 can be arranged in the gas permeable hole 81 to ensure the gas permeability of the gas permeable hole 81 while preventing foreign matter from entering the controller housing 8 through the gas permeable hole 81. The arrangement of the gas permeable film 82 is well known to those skilled in the art, and will not be described here. The water-blocking plug 10 can be installed on the controller housing 8 to block the gas permeable film 82, thereby shielding the gas permeable film 82 to prevent high-pressure water or sand and gravel from directly acting on the gas permeable film 82, thereby protecting the gas permeable film 82. The position of the closed end 44 can correspond to the position of the gas permeable film 82 to shield and block the gas permeable film 82 without affecting the gas permeability of the gas permeable film 82, and to ensure the balance of the air pressure inside and outside the controller housing 8. The inner contour of the closed end 44 can match the outer contour of the gas permeable film 82 to ensure that the composite flow channel 4 does not affect the gas permeability of the gas permeable film 82.

[0041] Referring to Figure 2 and Figure 4 The first mounting hole 71 can be formed on the body 1 and can be used in cooperation with a fastener to install the water-blocking plug 10 at a predetermined position. The second mounting hole 72 corresponding to the position of the first mounting hole 71 can be formed on the controller housing 8, so that the body 1 can be connected to the controller housing 8 by a fastener 73 that sequentially penetrates the first mounting hole 71 and the second mounting hole 72. In the embodiments provided by the present disclosure, the first mounting hole 71 and the second mounting hole 71 can be threaded holes, and the fastener 73 can be a nut. By threadedly connecting the nut and the threaded holes, the body 1 and the controller housing 8 are connected with a strength that can be disassembled, thereby facilitating maintenance and repair of the components. Figure 1 As shown in FIG. 7, the first mounting hole 71 can be arranged on the body 1 away from the composite flow channel 4 to effectively prevent fluid leakage while ensuring the pressure reduction and speed reduction effect of the fluid in the composite flow channel 4.

[0042] According to the third aspect of the present disclosure, a vehicle is provided, which includes the above-mentioned controller and has all the advantages of the controller provided by the present disclosure, which will not be described here.

Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0044] It should be further noted that various specific technical features described in the above specific embodiments can be combined in any suitable manner, and the disclosure will not be repeated here for various possible combinations.

[0045] In addition, various different embodiments of the disclosure can also be combined with each other as long as they do not contradict the idea of the disclosure, and they should also be considered as disclosed by the disclosure.
