Description

Technical Field

[0001] The utility model relates to the field of electronic equipment, in particular to a housing and a controller. Background Art

[0002] In a vehicle, a controller, such as an ECU (Electronic Control Unit), generally includes a housing and internal components (such as a circuit board). In order to prevent dust and water vapor in the environment from entering the ECU and affecting the normal operation of the circuit board, a certain IP (Ingress Protection) protection level should be required when designing the ECU housing to ensure the dust and water resistance of the electronic equipment.

[0003] In the prior art, the outer casing is generally sealed by flanging, pressing or applying sealant to ensure the dustproof and waterproof performance of the electronic equipment. However, for some ECUs with lower IP protection level requirements, the above-mentioned design of sealing the outer casing to achieve dustproof and waterproof performance of the outer casing is an over-design. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the design of achieving dustproof and waterproof shell by sealing the shell is over-designed under the low IP protection level requirements of electronic equipment. The utility model provides a shell and a controller, which can reduce the production cost of the shell while meeting the lower IP protection level requirements of electronic equipment.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a housing including:

[0006] a first shell;

[0007] A second shell connected to the first shell along a first direction to enclose a shell inner cavity and a first gap, wherein the first gap is located between an outer edge of the first shell and an outer edge of the second shell;

[0008] An annular blocking member, provided on the first shell, a portion of which serves as a portion of the cavity wall of the inner cavity of the shell;

[0009] An annular groove is provided in the second shell, one end of the annular blocking member is located in the annular groove and is spaced apart from the groove wall of the annular groove to form a second gap, the shell inner cavity, the second gap and the first gap are connected in sequence, and along the second direction, the annular blocking member is located between the shell inner cavity and the first gap.

[0010] With the above technical solution, the first gap is located between the outer edge of the first shell and the outer edge of the second shell, and the first gap is connected to the inner cavity of the shell, so one end of the first gap is connected to the outside, and the other end is connected to the inner cavity of the shell. Since the inner cavity of the shell, the second gap and the first gap are connected in sequence, the inner cavity of the shell, the second gap, the first gap and the outside are connected in sequence. In a static state, the outside air pressure is the same as the air pressure of the inner cavity of the shell. When the outside fluid (such as water vapor or wind) carries dust through the first gap into the second gap, the annular blocking member is located between the inner cavity of the shell and the first gap along the second direction. Therefore, when the outside fluid enters the second gap, the outside fluid will be blocked by the annular blocking member, resulting in a reduction in its speed.

[0011] According to Bernoulli's principle, when the speed of the fluid decreases, its kinetic energy decreases, while the pressure increases. Therefore, when the external fluid enters the second gap, the speed of the external fluid decreases and the fluid pressure increases. Since the second gap is connected to the inner cavity of the shell, the fluid pressure in the inner cavity of the shell (i.e., the air pressure in the inner cavity of the shell) also increases accordingly. Therefore, at this time, the fluid pressure in the inner cavity of the shell (i.e., the air pressure in the inner cavity of the shell) is greater than the external air pressure, which blocks the external fluid from entering the inner cavity of the shell, thereby blocking dust and water vapor from entering the inner cavity of the shell, achieving a dustproof and waterproof effect.

[0012] In addition, the prior art generally adopts methods such as flanging and pressing or applying sealant to seal the housing to ensure the dustproof and waterproof performance of the electronic device, but the sealing methods of the above two housings require investment in corresponding pressing equipment and gluing equipment, resulting in high production costs. By adopting the technical solution of the embodiment of the present application, by designing the structure of the aforementioned housing, it is also possible to block dust and water vapor from entering the inner cavity, thereby achieving a dustproof and waterproof effect. Among them, the matching method of the annular blocking member and the annular groove is mechanical matching, and the method of flanging and pressing or applying sealant in the prior art is not adopted. Therefore, there is no need to invest in corresponding pressing equipment and gluing equipment, thereby reducing the production cost of the housing.

[0013] According to another specific embodiment of the present utility model, an embodiment of the present utility model discloses a housing, wherein along the second direction, the first gap is arranged opposite to the annular blocking member.

[0014] By adopting the above technical solution, the first gap and the annular blocking member are arranged relative to each other along the second direction, so that the external fluid entering through the first gap can collide with the annular blocking member, and the speed of the external fluid can be reduced, thereby achieving the waterproof and dustproof performance of the shell according to the Bernoulli principle.

[0015] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a shell, the annular blocking member is protruding from the outer edge of the first shell, the annular blocking member extends along the first direction, and the annular groove is located at the outer edge of the second shell.

[0016] By adopting the above technical solution, the annular blocking member is protruded from the outer edge of the first shell, and the annular groove is located at the outer edge of the second shell, wherein a portion of the annular blocking member serves as a portion of the cavity wall of the inner cavity of the shell. Therefore, the annular blocking member is arranged on the outer edge of the first shell and the annular groove is arranged on the outer edge of the second shell to ensure that the space of the inner cavity of the shell is large enough, so that the spatial layout of the inner cavity of the shell is not hindered by the dustproof and waterproof structural design.

[0017] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a housing, wherein along a third direction, the annular blocking member is a continuous annular structure, and the annular groove is a continuous annular structure.

[0018] By adopting the above technical solution, along the third direction, the annular blocking member is a continuous annular structure, and the annular groove is a continuous annular structure, that is, the annular blocking member surrounds the entire outer edge of the first shell along the third direction without interruption in the middle, and the annular groove surrounds the entire outer edge of the second shell along the third direction without interruption in the middle. Thus, the first shell is connected to the second shell along the first direction, and when external fluid enters the second gap through the first gap, along the third direction, at the connection between the first shell and the second shell, the dustproof and waterproof effects achieved according to the Bernoulli principle exist everywhere, thereby improving the dustproof and waterproof performance of the shell of the embodiment of the present application.

[0019] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a shell, the first shell and the second shell are both made of rigid material, the annular blocking member includes a first protrusion, and the first protrusion is protruded on the annular blocking member along the direction toward the side groove wall of the annular groove, and the gap between the first protrusion and the side groove wall of the annular groove is smaller than the gap between the rest of the annular blocking member and the side groove wall of the annular groove.

[0020] By adopting the above technical solution, the annular blocking member includes a first convex portion, which is convexly arranged on the annular blocking member along the direction of the side groove wall of the annular groove, so that the gap between the first convex portion and the side groove wall of the annular groove is smaller than the gap between the rest of the annular blocking member and the side groove wall of the annular groove. Therefore, when external fluid carrying dust enters the second gap, it will be blocked by the first convex portion, blocking the external fluid from flowing into the inner cavity of the shell, thereby blocking dust and water vapor from entering the inner cavity of the shell, achieving a mechanical dustproof and waterproof effect.

[0021] In addition, since both the first shell and the second shell are made of rigid materials, there is still a gap between the first protrusion and the side groove wall of the annular groove. According to Bernoulli's principle, when the external fluid enters the second gap, the external fluid will be blocked by the annular blocking member, resulting in a decrease in its speed and an increase in pressure. Since the second gap is connected to the inner cavity of the shell, the fluid pressure in the inner cavity of the shell (i.e., the air pressure in the inner cavity of the shell) is also increased accordingly. Therefore, at this time, the fluid pressure in the inner cavity of the shell (i.e., the air pressure in the inner cavity of the shell) is greater than the external air pressure, blocking the external fluid from entering the inner cavity of the shell, thereby blocking dust and water vapor from entering the inner cavity of the shell, achieving a dustproof and waterproof effect.

[0022] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a shell, the first shell and the second shell are both made of rigid material, the annular groove includes a second convex portion, and the second convex portion is protruded on the side groove wall of the annular groove along the direction toward the annular blocking member, and the gap between the second convex portion and the annular blocking member is smaller than the gap between the rest of the side groove wall of the annular groove and the annular blocking member.

[0023] By adopting the above technical solution, the annular groove includes a second convex portion, and the second convex portion is convexly arranged on the side groove wall of the annular groove along the direction toward the annular blocking member, so that the gap between the second convex portion and the annular blocking member is smaller than the gap between the remaining part of the side groove wall of the annular groove and the annular blocking member. Therefore, when external fluid carrying dust enters the second gap, it will be blocked by the second convex portion, blocking the external fluid from flowing into the inner cavity of the shell, thereby blocking dust or water vapor from entering the inner cavity of the shell, achieving a mechanical dustproof and waterproof effect.

[0024] In addition, since both the first shell and the second shell are made of rigid materials, there is still a gap between the second protrusion and the annular blocking member. According to Bernoulli's principle, when the external fluid enters the second gap, the external fluid will be blocked by the annular blocking member, resulting in a decrease in its speed and an increase in pressure. Since the second gap is connected to the inner cavity of the shell, the fluid pressure in the inner cavity of the shell (i.e., the air pressure in the inner cavity of the shell) is also increased accordingly. Therefore, at this time, the fluid pressure in the inner cavity of the shell (i.e., the air pressure in the inner cavity of the shell) is greater than the external air pressure, blocking the external fluid from entering the inner cavity of the shell, thereby blocking dust and water vapor from entering the inner cavity of the shell, achieving a dustproof and waterproof effect.

[0025] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a shell, the first shell includes a fixing hole, the fixing hole is arranged on the top wall of the shell inner cavity, the fixing hole extends along a first direction, the second shell includes a first through hole, along the first direction, the first through hole and the fixing hole are arranged opposite to each other, the first through hole and the fixing hole are fixedly connected by bolts, so that the first shell and the second shell are fixedly connected.

[0026] By adopting the above technical scheme, the first through hole and the fixing hole are fixedly connected by bolts to fix the first shell and the second shell. Therefore, the embodiment of the present application realizes the dustproof and waterproof performance of the outer shell through the cooperation of the annular blocking member and the annular groove, and the bolts are matched with the first through hole and the fixing hole to realize the fixed connection of the outer shell. Therefore, the realization of the dustproof and waterproof function of the outer shell and the fixation of the outer shell are completed by different structures, which can not only ensure the stability of the outer shell connection, but also achieve the technical effect of dustproof and waterproof.

[0027] According to another specific embodiment of the present utility model, an embodiment of the present utility model discloses a housing, wherein the first gap extends along a second direction.

[0028] By adopting the above technical solution, exemplarily, the second direction in the present application is parallel to the horizontal direction. Since the inner cavity of the shell, the second gap and the first gap are connected in sequence along the second direction, and one end of the first gap is connected to the outside, the first gap is parallel to the horizontal direction, so that the external fluid (such as water flow) sliding down the outer wall of the first shell or the second shell is difficult to pass into the first gap, thereby improving the waterproof performance of the shell of the embodiment of the present application

[0029] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a housing, wherein along the second direction, the cross section of the annular blocking member is conical, and the cross section of the annular groove is V-shaped.

[0030] With the above technical solution, along the second direction, the cross section of the annular blocking member is a tapered shape with a large width at one end and a small width at the other end, and the cross section of the annular groove is a V-shape with a large width at one end and a small width at the other end. When connecting the first shell and the second shell, the end of the annular blocking member with a smaller width is inserted into the end of the annular groove with a larger width before the end with a larger width, which facilitates the connection of the first shell and the second shell. In addition, during the processing, the annular groove with a V-shaped cross section facilitates the retraction of the processing tool.

[0031] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a shell, the first shell includes multiple fixing parts, and the multiple fixing parts are used to connect and fix with external equipment. Along the fourth direction, the multiple fixing parts are arranged on both sides of the first shell, and the fixing parts include a second through hole, and the second through hole penetrates the fixing parts along the first direction.

[0032] By adopting the above technical solution, the first shell includes a plurality of fixing parts, and the plurality of fixing parts are used to be connected and fixed with external equipment, thereby improving the stability of the fixed connection.

[0033] The embodiment of the utility model further discloses a controller, comprising:

[0034] The housing according to any one of the above embodiments;

[0035] A circuit board is arranged in the inner cavity of the shell.

[0036] By adopting the above technical solution, the dustproof level of the controller only needs to reach the level that the intrusion of dust will not affect the normal operation of the ECU, and the waterproof level only needs to reach the level that when the ECU is vertically tilted 15 degrees, dripping water will not cause damage to the ECU. Therefore, the controller adopts the shell of the embodiment of the present application, which can meet its IP protection level requirements and achieve the corresponding dustproof and waterproof effect.

[0037] According to another specific embodiment of the utility model, an embodiment of the utility model discloses a controller, the circuit board includes a third through hole, along the first direction, the first through hole of the second shell, the third through hole and the fixing hole of the first shell are arranged opposite to each other, the fixing hole of the first shell, the first through hole of the second shell and the third through hole are fixedly connected by bolts to fix the first shell, the circuit board and the second shell.

[0038] By adopting the above technical scheme, the fixing hole of the first shell, the first through hole and the third through hole of the second shell are fixedly connected by bolts, so that the first shell, the circuit board and the second shell are fixedly connected. The embodiment of the present application realizes the dustproof and waterproof performance of the outer shell through the cooperation of the annular blocking member and the annular groove, and the bolts are matched with the first through hole, the fixing hole and the third through hole to realize the fixed connection of the outer shell. Therefore, the realization of the dustproof and waterproof function of the outer shell and the fixation of the outer shell are completed by different structures, which can not only ensure the stability of the outer shell connection, but also achieve the technical effect of dustproof and waterproof.

[0059] refer to Figure 1 to Figure 2bThe present application provides a housing 10 , comprising: a first housing 11 , a second housing 12 , an annular blocking member 111 and an annular groove 121 .

[0060] refer to Figure 2a and Figure 2b Combined with Figure 3 The first shell 11 has an open end and a closed end. The first shell 11 includes a first wall 115, a second wall 116, a third wall 117, a fourth wall 118 and a bottom wall 119. The first wall 115 and the third wall 117 are arranged opposite to each other, the second wall 116 and the fourth wall 118 are arranged opposite to each other, and the bottom wall 119 is the closed end of the first shell 11, and the bottom wall 119 is arranged opposite to the open end of the first shell 11.

[0061] Along the first direction (such as Figure 2a The second shell 12 is connected to one end of the opening of the first shell 11 on one side of the first shell 11 to enclose a shell inner cavity 13 and a first gap 14. The first gap 14 is located between an outer edge 110 of the first shell 11 and an outer edge 120 of the second shell 12. One end of the first gap 14 is connected to the shell inner cavity 13, and the other end is connected to the outside.

[0062] refer to Figure 2b Combined with Figure 4 , Figure 4 yes Figure 3 The partial enlarged view of the A area in the middle, the annular blocking member 111 is provided at the outer edge 110 of the first shell 11, and along the first direction (such as Figure 2b Specifically, the annular blocking member 111 includes an outer side wall 1111, an inner side wall 1112 and a lower side wall 1113, and extends along the second direction (as shown in the Z direction). Figure 2b The outer side wall 1111 and the inner side wall 1112 are respectively the left and right side walls of the annular blocking member 111, and the lower side wall 1113 is a wall located below the annular blocking member 111.

[0063] A portion of the annular blocking member 111 serves as a portion of the cavity wall 131 of the housing cavity 13. Specifically, the cavity wall 131 of the housing cavity 13 includes the inner wall of the first wall 115, the inner wall of the second wall 116, the inner wall of the third wall 117, the inner wall of the fourth wall 118, the inner wall of the bottom wall 119, and the inner side wall 1112 of the annular blocking member 111.

[0064] The annular groove 121 is provided on the side of the second housing 12 facing the first housing 11, and is located at the outer edge 120 of the second housing 12. Along the first direction, the annular blocking member 111 is located at the annular groove 121, and is spaced apart from the groove wall 1211 of the annular groove 121. Exemplarily, the groove wall 1211 of the annular groove 121 includes an outer groove wall 12111, an inner groove wall 12112, and a lower groove wall 12113. The outer groove wall 12111 and the inner groove wall 12112 are the left and right side walls of the annular groove 121, and the lower groove wall 12113 is a wall located below the annular groove 121. The outer wall 1111 of the annular blocking member 111 is spaced apart from the outer groove wall 12111, the inner wall 1112 of the annular blocking member 111 is spaced apart from the inner groove wall 12112, and the lower side wall 1113 of the annular blocking member 111 is spaced apart from the lower side groove wall 12113.

[0065] Along the first direction, a second gap 15 is formed between the annular blocking member 111 and the groove wall 1211 of the annular groove 121. The second gap 15 includes an outer gap 156, an inner gap 155 and a bottom gap 157. Figure 4 The outer gap 156 and the inner gap 155 are connected and are respectively located on both sides of the annular blocking member 111, and the bottom gap 157 is located at the lower end of the annular blocking member 111. Specifically, the outer gap 156 is located between the outer wall 1111 and the outer groove wall 12111 of the annular blocking member 111, the inner gap 155 is located between the inner wall 1112 and the inner groove wall 12112 of the annular blocking member 111, and the bottom gap 157 is located between the lower side wall 1113 and the lower groove wall 12113 of the annular blocking member 111. The outer gap 156 and the bottom gap 157 are connected to the first gap 14, and the inner gap 155 is connected to the inner cavity 13 of the housing.

[0066] The shell inner cavity 13, the second gap 15 and the first gap 14 are connected in sequence. In other words, the shell inner cavity 13, the inner gap 155, the bottom gap 157, the outer gap 156 and the first gap 14 are connected in sequence, and along the second direction, the annular blocking member 111 is located between the shell inner cavity 13 and the first gap 14.

[0067] With the above technical solution, since one end of the first gap 14 is connected to the shell cavity 13 and the other end is connected to the outside, the shell cavity 13, the inner gap 155, the bottom gap 157, the outer gap 156, the first gap 14 and the outside are connected in sequence, and in a static state, the outside air pressure is the same as the air pressure of the shell cavity 13. When the outside fluid (such as water vapor or wind) carries dust through the first gap 14 and enters the outer gap 156, the annular blocking member 111 is located between the shell cavity 13 and the first gap 14 along the second direction. Therefore, when the outside fluid enters the outer gap 156, the outside fluid will be blocked by the annular blocking member 111, resulting in a reduction in its speed.

[0068] According to Bernoulli's principle, when the speed of a fluid decreases, its kinetic energy decreases, while the pressure increases. Therefore, when the external fluid enters the outer gap 156, the speed of the external fluid decreases and the fluid pressure increases. Since the outer gap 156 and the bottom gap 157 are connected to the inner gap 155, the fluid pressure in the bottom gap 157 and the inner gap 155 increases accordingly, and the inner gap 155 is connected to the shell cavity 13, so the fluid pressure in the shell cavity 13 (i.e., the air pressure in the shell cavity 13) also increases. Therefore, at this time, the fluid pressure in the shell cavity 13 (i.e., the air pressure in the shell cavity 13) is greater than the external air pressure, which blocks the external fluid from entering the shell cavity 13, thereby blocking dust and water vapor from entering the shell cavity 13, achieving a dustproof and waterproof effect.

[0069] In addition, the prior art generally adopts methods such as flanging and pressing or applying sealant to seal the outer shell to ensure the dustproof and waterproof performance of the electronic device, but the sealing methods of the above two shells require investment in corresponding pressing equipment and gluing equipment, resulting in high production costs. However, by adopting the technical solution of the embodiment of the present application, by designing the structure of the aforementioned shell 10, it is also possible to block dust and water vapor from entering the inner cavity, thereby achieving a dustproof and waterproof effect. Among them, the matching method of the annular blocking member 111 and the annular groove 121 is mechanical matching, and the method of flanging and pressing or applying sealant in the prior art is not adopted. Therefore, there is no need to invest in corresponding pressing equipment and gluing equipment, thereby reducing the production cost of the shell 10 of the embodiment of the present application.

[0070] refer to Figure 1 to Figure 2b The first housing 11 includes a plurality of fixing members 114, and the plurality of fixing members 114 are used to connect and fix with external devices to improve the stability of the fixed connection. Figure 2a A plurality of fixing members 114 are provided on both sides of the first housing 11. For example, the number of fixing members 114 in the present application is three. Figure 1 and Figure 2b, one fixing member 114 is disposed on the first wall 115, and the other two fixing members 114 are disposed on the third wall 117. Each fixing member 114 includes a second through hole 1141, which penetrates the fixing member 114 along the first direction, and the second through hole 1141 cooperates with a fixing bolt (not shown in the figure) to connect and fix the housing 10 of the embodiment of the present application to an external device (such as a car door).

[0071] It should be pointed out that in the present application, the number of fixing members 114 is not limited to three, and their locations are not limited to the first wall 115 and the third wall 117. In some possible embodiments, the number of fixing members 114 may be two or four, and their locations may be on the second wall 116 and the fourth wall 118.

[0072] refer to Figure 4 , along the second direction (such as Figure 4 The first gap 14 is arranged opposite to the annular blocking member 111, that is, along the first direction (as shown in the P direction) Figure 4 The height of the first gap 14 is higher than the height of the second gap 15. The external fluid entering through the first gap 14 can collide with the annular blocking member 111, and the speed of the external fluid can be reduced, so that the waterproof and dustproof performance of the housing 10 can be achieved according to the Bernoulli principle.

[0073] refer to Figure 4 , along the second direction, the cross section of the annular blocking member 111 is a tapered shape with a large width at one end and a small width at the other end, and the cross section of the annular groove 121 is a V-shape with a large width at the upper end and a small width at the lower end. When connecting the first shell 11 and the second shell 12, the end with a smaller width of the annular blocking member 111 is inserted into the end with a larger width of the annular groove 121 before the end with a larger width, which facilitates the connection between the first shell 11 and the second shell 12. In addition, during the processing, the annular groove 121 with a V-shaped cross section facilitates the retraction of the processing tool.

[0074] refer to Figure 4 , the first gap 14 is along the second direction (such as Figure 4 By way of example, the second direction in the present application is parallel to the horizontal direction. Since the shell cavity 13, the second gap 15 and the first gap 14 are sequentially connected along the second direction, and one end of the first gap 14 is connected to the outside, the first gap 14 is parallel to the horizontal direction, so that it is difficult for the external fluid (such as water flow) sliding down the outer wall of the first shell 11 or the second shell 12 to pass into the first gap 14, thereby improving the waterproof performance of the shell 10 of the embodiment of the present application.

[0075] refer to Figure 5 and Figure 6, the annular groove 121 is located at the outer edge 120 of the second housing 12. Figure 7 and Figure 8 Combined with Figure 3 and Figure 4 The annular blocking member 111 is convexly disposed on the outer edge 110 of the first shell 11, and the annular blocking member 111 extends along the first direction. Among them, since the cavity wall 131 of the shell cavity 13 includes the inner side wall 1112 of the annular blocking member 111. Therefore, the annular blocking member 111 is disposed on the outer edge 110 of the first shell 11, and the annular groove 121 is disposed on the outer edge 120 of the second shell 12, so that the space of the shell cavity 13 is large enough, and the space arrangement of the shell cavity 13 is not hindered by the dustproof and waterproof structural design.

[0076] Furthermore, the embodiment of the present application forms a second gap 15 between the annular blocking member 111 and the annular groove 121 through the cooperation between the two, and the shell cavity 13, the inner gap 155, the bottom gap 157, the outer gap 156, the first gap 14 and the outside are connected in sequence, thereby achieving the dustproof and waterproof performance of the shell 10 of the embodiment of the present application. Therefore, the shell 10 of the embodiment of the present application can be placed forward or inverted, or tilted at a certain angle, and the embodiment of the present application has a variety of usage scenarios.

[0077] In addition, it should be pointed out that the embodiment of the present application does not limit the positional relationship between the annular groove 121 and the first shell 11 and the second shell 12, nor does it limit the positional relationship between the annular blocking member 111 and the first shell 11 and the second shell 12. Since the embodiment of the present application forms the second gap 15 between the annular blocking member 111 and the annular groove 121 through the cooperation between the two, and the shell cavity 13, the inner gap 155, the bottom gap 157, the outer gap 156, the first gap 14 and the outside are sequentially connected, thereby achieving the dustproof and waterproof performance of the shell 10 of the embodiment of the present application, in some possible embodiments, the annular blocking member 111 can be protruding from the outer edge 120 of the second shell 12 and extending along the first direction, and the annular groove 121 can be located at the outer edge 110 of the first shell 11.

[0078] refer to Figure 5 and Figure 7 , along the third direction (such as Figure 5The annular blocking member 111 is a continuous annular structure, and the annular groove 121 is a continuous annular structure. The above-mentioned continuous annular structure can be interpreted as the annular blocking member 111 and the annular groove 121 being continuous and uninterrupted annular structures, rather than an annular structure with a breakpoint in the middle. That is, the annular blocking member 111 surrounds the outer edge 110 of the entire first shell 11 along the third direction without interruption in the middle, and the annular groove 121 surrounds the outer edge 120 of the entire second shell 12 along the third direction without interruption in the middle. Thus, the first shell 11 is connected to the second shell 12 along the first direction, and when an external fluid enters the second gap 15 through the first gap 14, along the third direction, at the connection between the first shell 11 and the second shell 12, the dustproof and waterproof effects achieved according to the Bernoulli principle exist everywhere, thereby improving the dustproof and waterproof performance of the shell 10 of the embodiment of the present application. ,

[0079] refer to Figure 4 Combined with Figure 6 and Fig. 9 The first shell 11 includes a fixing hole 113, which is provided on the top wall of the shell cavity 13, and the fixing hole 113 extends along the first direction. Specifically, the bottom wall 119 is provided with a fixing hole 113 extending along the first direction (such as Fig. 9 The fixing hole 113 is convexly arranged at one end of the boss 1191 along the first direction, and a rib plate 1192 surrounding the fixing hole 113 is also provided. One end of the rib plate 1192 is fixed to the bottom wall 119, and the other end extends along the first direction. The rib plate 1192 is used to enhance the stability of the fixing hole 113. The second housing 12 includes a first through hole 123. The first through hole 123 and the fixing hole 113 are arranged opposite to each other along the first direction. The first through hole 123 and the fixing hole 113 are fixedly connected by bolts 16, so that the first housing 11 and the second housing 12 are fixedly connected.

[0080] The first through hole 123 and the fixing hole 113 are fixedly connected by bolts 16 to fix the first shell 11 and the second shell 12 in connection. As mentioned above, the embodiment of the present application realizes the dustproof and waterproof performance of the shell 10 of the embodiment of the present application through the cooperation of the annular blocking member 111 and the annular groove 121. The bolts 16 are coordinated with the first through hole 123 and the fixing hole 113 to realize the fixed connection of the shell 10. Therefore, the realization of the dustproof and waterproof function of the shell 10 and the fixation of the shell 10 are completed by different structures, which can not only ensure the stability of the connection of the shell 10, but also achieve the technical effect of dustproof and waterproof.

[0081] In addition, as mentioned above, the realization of the dustproof and waterproof function of the housing 10 in the embodiment of the present application is accomplished by different structures from the fixing of the housing 10, that is, the realization of the dustproof and waterproof function of the housing 10 in the embodiment of the present application does not depend on the fixing method of the housing 10. Therefore, the features of the embodiment of the present application for realizing the dustproof and waterproof performance (i.e. the features of the annular blocking member 111 and the annular groove 121 cooperating with each other) are independent, so the features of the embodiment of the present application for realizing the dustproof and waterproof performance (i.e. the features of the annular blocking member 111 and the annular groove 121 cooperating with each other) can be applied to other housings 10 with lower requirements for connection stability, for example, the features of the annular blocking member 111 and the annular groove 121 cooperating with each other are applied to products with magnetic connection, and the application scenarios of the embodiment of the present application are rich.

[0082] Furthermore, the prior art uses flanging and pressing or applying sealant to seal the housing of electronic equipment, which requires adding pressing or curing steps in the production process, resulting in a long production cycle. However, the technical solution of the embodiment of the present application is adopted, along the first direction, only the annular blocking member 111 is placed in the annular groove 121, and the bolt 16 is passed through the first through hole 123 and the fixing hole 113, so that the first housing 11 and the second housing 12 are matched and fastened, and the assembly of the housing 10 of the embodiment of the present application can be completed, which simplifies the production steps and further reduces the production cost.

[0083] Furthermore, in the prior art, when flanging and pressing are used to seal the housing of an electronic device, there is still a problem of low product yield due to difficulty in controlling the force of the pressing equipment. However, by using the technical solution of the embodiment of the present application, along the first direction, it is only necessary to place the annular blocking member 111 in the annular groove 121, and then tighten the bolt 16 with the first through hole 123 and the fixing hole 113 to complete the assembly of the housing 10. The above assembly process is simple, so the yield of the processed product is high.

[0084] Furthermore, since the dustproof and waterproof performance of the shell 10 is achieved by the cooperation between the annular blocking member 111 and the annular groove 121, and the fixed connection of the shell 10 is achieved by the cooperation between the bolt 16, the first through hole 123 and the fixing hole 113, the material requirement for the first shell 11 and the second shell 12 is a rigid material that can be processed into the annular blocking member 111 and the annular groove 121. Therefore, the embodiments of the present application can be promoted and used for injection molding, stamping, and die-casting products, and the application scenarios of the embodiments of the present application are rich.

[0085] refer to Fig.10aIn some possible embodiments, the annular blocking member 111 includes a first protrusion 112, and the first protrusion 112 is protruded from the annular blocking member 111 along the direction of the side groove wall 1211 toward the annular groove 121. Specifically, along the second direction, the first protrusion 112 is located on the inner wall 1112 of the annular blocking member 111, that is, the first protrusion 112 is located in the inner gap 155.

[0086] The gap between the first protrusion 112 and the side groove wall 1211 of the annular groove 121 is smaller than the gap between the rest of the annular blocking member 111 and the side groove wall 1211 of the annular groove 121. Specifically, the gap between the first protrusion 112 and the side groove wall 1211 of the annular groove 121 is: the gap between the first protrusion 112 and the inner groove wall 12112, and the gap between the first protrusion 112 and the inner groove wall 12112 is the first protrusion gap 151. Exemplarily, the rest of the annular blocking member 111 includes the outer side wall 1111 and the lower side wall 1113. Accordingly, the gap between the rest of the annular blocking member 111 and the side groove wall 1211 of the annular groove 121 refers to: the gap between the outer side wall 1111 and the outer side groove wall 12111 (i.e., the outer gap 156) and the gap between the lower side wall 1113 and the lower side groove wall 12113 (i.e., the bottom gap 157).

[0087] The annular blocking member 111 includes a first protrusion 112, which is protruded from the annular blocking member 111 along the direction toward the inner groove wall 12112, so that the gap between the first protrusion 112 and the inner groove wall 12112 is smaller than the outer gap 156 and the bottom gap 157. Therefore, when external fluid (such as water vapor or wind) carries dust into the inner gap 155, it will be blocked by the first protrusion 112 and prevented from flowing into the shell cavity 13, thereby preventing dust and water vapor from entering the shell cavity, thereby achieving a mechanical dustproof and waterproof effect.

[0088] In addition, since both the first shell 11 and the second shell 12 are made of rigid materials, there is still a gap between the first protrusion 112 and the inner groove wall 12112. According to Bernoulli's principle, when the external fluid enters the outer gap 156, the external fluid will be blocked by the annular blocking member 111, resulting in a decrease in its speed and an increase in pressure. Since the outer gap 156 and the bottom gap 157 are connected to the inner gap 155, the fluid pressure in the inner gap 155 and the bottom gap 157 increases accordingly, and the inner gap 155 is connected to the shell cavity 13, so the fluid pressure in the shell cavity 13 (i.e., the air pressure in the shell cavity 13) also increases. Therefore, at this time, the fluid pressure in the shell cavity 13 (i.e., the air pressure in the shell cavity 13) is greater than the external air pressure, blocking the external fluid from entering the shell cavity 13, thereby blocking dust and water vapor from entering the shell cavity 13, achieving a dustproof and waterproof effect.

[0089] It should be pointed out that the embodiment of the present application does not limit the positional relationship between the first protrusion 112 and the annular blocking member 111. In some possible embodiments, along the second direction, the first protrusion 112 can be located on the outer wall 1111 of the annular blocking member 111, that is, the first protrusion 112 can be located in the outer gap 156.

[0090] refer to Fig.10b In some possible embodiments, the annular groove 121 includes a second protrusion 122, and the second protrusion 122 is protruded from the side groove wall 1211 of the annular groove 121 along the direction toward the inner wall 1112 of the annular blocking member 111. Specifically, along the second direction, the second protrusion 122 is located on the inner groove wall 12112 of the annular groove 121, that is, the second protrusion 122 is located in the inner gap 155.

[0091] The gap between the second protrusion 122 and the annular stopper 111 is smaller than the gap between the rest of the side groove wall 1211 of the annular groove 121 and the annular stopper 111. Specifically, the gap between the second protrusion 122 and the annular stopper 111 refers to: the gap between the second protrusion 122 and the inner side wall 1112, and the gap between the second protrusion 122 and the inner side wall 1112 is the second protrusion gap 153. Exemplarily, the rest of the side groove wall 1211 includes the outer groove wall 12111 and the lower groove wall 12113. Correspondingly, the gap between the rest of the side groove wall 1211 of the annular groove 121 and the annular stopper 111 refers to: the gap between the outer groove wall 12111 and the outer wall 1111 (i.e., the outer gap 156), and the gap between the lower groove wall 12113 and the lower side wall 1113 (i.e., the bottom gap 157).

[0092] The annular groove 121 includes a second convex portion 122, which is convexly arranged on the side groove wall 1211 of the annular groove 121 along the direction toward the inner side wall 1112 of the annular blocking member 111, so that the gap between the second convex portion 122 and the inner side wall 1112 is smaller than the outer gap 156 and the bottom gap 157. Therefore, when an external fluid (such as water vapor or wind) carries dust into the inner gap 155, it will be blocked by the second convex portion 122, blocking the external fluid from flowing into the housing cavity 13, thereby blocking dust and water vapor from entering the housing cavity 13, achieving a mechanical dustproof and waterproof effect.

[0093] In addition, since both the first shell 11 and the second shell 12 are made of rigid materials, there is still a gap between the second protrusion 122 and the inner side wall 1112 of the annular blocking member 111. According to Bernoulli's principle, when the external fluid enters the outer gap 156, the external fluid will be blocked by the annular blocking member 111, resulting in a decrease in its speed and an increase in pressure. Since the outer gap 156 and the bottom gap 157 are connected to the inner gap 155, the fluid pressure in the inner gap 155 and the bottom gap 157 increases accordingly, and the inner gap 155 is connected to the shell cavity 13, so the fluid pressure in the shell cavity 13 (i.e., the air pressure in the shell cavity 13) also increases. Therefore, at this time, the fluid pressure in the shell cavity 13 (i.e., the air pressure in the shell cavity 13) is greater than the external air pressure, blocking the external fluid from entering the shell cavity 13, thereby blocking dust and water vapor from entering the shell cavity 13, achieving a dustproof and waterproof effect.

[0094] It should be pointed out that the embodiment of the present application does not limit the positional relationship between the second protrusion 122 and the annular groove 121. In some possible embodiments, along the second direction, the first protrusion 112 can be located on the outer groove wall 12111 of the annular groove 121, that is, the second protrusion 122 can be located in the outer gap 156.

[0095] refer to Figure 2a and Figure 2b The present application provides a controller (ECU, Electronic Control Unit) 17, comprising: a housing 10 of any embodiment described above and a circuit board 18, the circuit board 18 being arranged in the housing inner cavity 13. The dustproof level of the controller 17 only needs to reach the level that the intrusion of dust will not affect the normal operation of the ECU, and the waterproof level only needs to reach the level that when the ECU is vertically tilted 15 degrees, dripping water will not cause damage to the ECU. Therefore, the controller 17 adopts the housing 10 of the embodiment of the present application, which can meet its IP protection level requirements and achieve the corresponding dustproof and waterproof effects.

[0096] refer to Figure 2a The circuit board 18 is also provided with a plurality of signal connectors 182, which are connected to the circuit board 18 for transmitting signals to external devices. Exemplarily, the second wall 116 is provided with a signal connection hole 1161, which is used to accommodate the signal connector 182. The number of signal connectors 182 in the embodiment of the present application is two. In some possible implementations, the number of signal connectors 182 may be three or more, and the signal connection hole 1161 may be provided on the first wall 115, the third wall 117, the fourth wall 118 or the bottom wall 119, and the position of the signal connector 182 is set accordingly according to the position of the signal connection hole 1161.

[0097] refer to Figure 2bThe circuit board 18 includes a third through hole 181, along the first direction (such as Figure 2b The first through hole 123, the third through hole 181 of the second housing 12 and the fixing hole 113 of the first housing 11 are arranged opposite to each other, and the fixing hole 113 of the first housing 11, the first through hole 123 and the third through hole 181 of the second housing 12 are fixedly connected by bolts 16, so that the first housing 11, the circuit board 18 and the second housing 12 are fixedly connected. Exemplarily, the number of the first through hole 123, the fixing hole 113 and the third through hole 181 in the embodiment of the present application is four. In some possible implementations, the number of the first through hole 123, the fixing hole 113 and the third through hole 181 may be six, eight or other numbers.

[0098] By adopting the above technical scheme, the fixing hole 113 of the first shell 11, the first through hole 123 and the third through hole 181 of the second shell 12 are fixedly connected by bolts 16, so that the first shell 11, the circuit board 18 and the second shell 12 are fixedly connected. In the embodiment of the present application, the dustproof and waterproof performance of the shell 10 is achieved by cooperating with the annular blocking member 111 and the annular groove 121, and the bolt 16 is matched with the first through hole 123, the fixing hole 113 and the third through hole 181 to achieve the fixed connection of the shell 10. Therefore, the realization of the dustproof and waterproof function of the shell 10 and the fixation of the shell 10 are completed by different structures, which can not only ensure the stability of the connection of the shell 10, but also achieve the technical effect of dustproof and waterproof.
