Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile controller, especially a kind of controller. BACKGROUND

[0002] Automobile central computing controller is generally composed of metal upper and lower shell and PCB (Printed Circuit Board), and is connected with the function area of vehicle body by 90° connector (the extension direction of the connector is parallel to the extension direction of PCB) connected with PCB. However, the customized 90° controller can only be customized to the supplier, which is large in size and can only be placed on one side of the automobile central computing controller. After placing the 90° controller, there is no extra space to place new controllers, so the cost is high and the expandability is poor.

[0003] At the same time, the automobile central computing controller is placed in the vehicle along the gravity direction, and in heavy rain weather, rainwater may soak the various connectors in the controller along the gravity direction along the shell of the controller, causing the connectors to be damaged and malfunction. Therefore, a structure is needed to prevent rainwater from soaking the connectors. SUMMARY

[0004] The utility model discloses a kind of controllers, and the first connector, Ethernet connector and second connector are prevented from being soaked by rainwater by the shielding of waterproof part, to prevent the first connector, Ethernet connector and second connector from being damaged and malfunctioning.

[0005] To solve the above technical problems, the embodiment of the utility model discloses a kind of controllers, and the controller includes:

[0006] The upper cover, PCB and metal lower cover connected in sequence, the upper cover and the metal lower cover define a containing cavity;Wherein,

[0007] The PCB is located in the containing cavity, and the PCB includes at least one first connector and Ethernet connector arranged at intervals, the first connector includes first frame and first pin group, the first frame surrounds the first pin group, and the PCB further includes at least one second pin group, the second pin group is arranged at intervals with the first connector, the Ethernet connector;

[0008] The upper cover includes a plurality of through holes and second frame, at least one first connector and Ethernet connector are surrounded by corresponding through holes respectively, and the second frame surrounds at least one second pin group to form at least one second connector.

[0009] The upper cover further comprises a waterproof part, which is arranged above the first connector, the Ethernet connector and the second connector along the gravity direction, and comprises opposite first and second side walls along the horizontal direction, two ends of the waterproof part extend towards the first and second side walls respectively and beyond two ends of the first connector, the Ethernet connector and the second connector to form a waterproof area in which the first connector, the Ethernet connector and the second connector are located.

[0010] With the above technical solution, the controller is placed in the vehicle along the gravity direction, and in heavy rain weather conditions, rainwater may enter the first connector, the second connector and the Ethernet connector along the outer surface of the upper cover along the gravity direction, causing damage to the controller. Therefore, the waterproof part is arranged above the first connector, the second connector and the Ethernet connector, and when rainwater falls, the rainwater will naturally flow along the surface of the waterproof part due to the shielding of the waterproof part, and finally flow to the two ends of the waterproof part and then drip. And since the two ends of the waterproof part exceed the two ends of the first connector, the Ethernet connector and the second connector, and the first connector, the Ethernet connector and the second connector are in the waterproof area at this time, they are prevented from being soaked by rainwater, thereby preventing damage to the first connector, the Ethernet connector and the second connector.

[0011] In addition, the technical solution realizes the function of the central computing controller through the upper cover, the PCB board including the Ethernet connector and the metal lower cover. The metal lower cover can meet the EMC (Electromagnetic Compatibility) requirement. The central computing controller generates electromagnetic radiation during operation and may also be subject to external electromagnetic interference. If not effectively shielded, these electromagnetic radiations may interfere with the normal operation of other electronic devices, affecting the overall performance and safety of the vehicle. In addition, external electromagnetic interference may cause the central computing controller to malfunction, data errors, etc. The metal lower cover has good electrical conductivity and magnetic permeability, which can effectively block and reflect electromagnetic radiation, thereby protecting the electronic components inside the central computing controller from electromagnetic interference and ensuring stable and reliable operation.

[0012] The PCB board has multiple modules to meet the operation requirements of the central computing controller, such as a CCV (Central Control Unit) module and a HPC (High-Voltage Power Control) module. The metal lower cover not only plays a certain mechanical protection role to prevent the controller from being physically damaged, but also ensures the heat dissipation requirements of multiple modules in the controller.

[0013] According to another specific embodiment of the present application, the first pin group comprises a plurality of first pins, each of the first pins has a thickness less than 0.64mm.

[0014] The second pin group comprises a plurality of second pins, each of the second pins has a thickness greater than or equal to 0.64mm.

[0015] With the above technical solution, for the first pin with a thickness less than 0.64mm, the first pin has a small volume and a soft texture as a whole, and the first connector (for example, which can be referred to as a miniaturized connector) containing the first pin can be purchased from a supplier based on the manufacturing difficulty. For the second pin with a thickness greater than or equal to 0.64mm, the volume of the second pin is greater than that of the first pin, and the structure of the second pin is relatively harder, thereby reducing the manufacturing difficulty. Therefore, the second pin group is directly connected to the PCB, and the second frame of the second connector is integrated with the upper cover, thereby reducing the volume of the second connector, and a plurality of second pin groups can be placed on the PCB to form a plurality of second connectors. In this way, the purchasing cost is reduced, and the demand for multiple connectors is met, thereby realizing the domain control function module of the controller.

[0016] Therefore, in combination with the foregoing, the controller in the present technical solution can integrate the central computing controller and the vehicle body domain controller, thereby reducing the cost and meeting the demand for multiple connectors.

[0017] According to another specific embodiment of the present application, the waterproof part at least comprises an arc segment, and the waterproof part can further comprise a vertical segment, and two ends of the arc segment are connected to the vertical segment respectively.

[0018] With the above technical solution, the positions of the first connector, the Ethernet connector and the second connector are random, for example, the first connector and the second connector can be arranged along the horizontal direction, or a plurality of Ethernet connectors can be arranged along the gravity direction.

[0019] When multiple Ethernet connectors are arranged along the gravity direction, the waterproof area where they are located has a length extending in the horizontal direction smaller than a length extending in the gravity direction. In this case, when raindrops fall down along the two ends of the waterproof part, due to the limited coverage of the waterproof area in the horizontal direction, it is possible that the raindrops will cross the defense line of the waterproof area and then enter the Ethernet connector located below. In order to avoid the damage of the Ethernet connector caused by this situation and ensure the normal operation of the Ethernet connector, the vertical section is arranged as a secondary waterproof measure. The vertical section can effectively intercept the raindrops falling from the two ends of the waterproof part and prevent the raindrops from further penetrating into the area where the Ethernet connector is located, thereby providing more reliable waterproof protection for the Ethernet connector.

[0020] According to another specific embodiment of the present application, the upper cover comprises a first inner wall, the first inner wall comprises a first part and a second part connected, in a direction perpendicular to the PCB, the first part is above the second part, the thickness of the first part is greater than the thickness of the second part, the metal lower cover comprises a second side wall, the second part surrounds the second side wall and is snap-connected with the second side wall.

[0021] By snap-connecting the second part with the second side wall, the upper cover and the metal lower cover are sealed. The second part surrounds the second side wall and is snap-connected with the second side wall, i.e. the first side wall encloses the second side wall, thereby effectively preventing external moisture and other impurities from entering the inside of the accommodation cavity, protecting the PCB inside the controller from the influence of external environmental factors and ensuring the stable and reliable operation of the controller.

[0022] According to another specific embodiment of the present application, the second part and the second side wall have a first gap therebetween, in a direction perpendicular to the PCB, the end of the first part and the end of the second side wall have a second gap therebetween, the first gap is smaller than the second gap, and the second gap is smaller than or equal to 0.1mm.

[0023] By the above technical solution, the controller is placed along the gravity direction, and at this time the first gap extends in the horizontal direction. When rainwater flows towards the first gap under the action of gravity, an effective barrier is formed due to the first gap being smaller than 0.1mm. Under the influence of surface tension and other factors, the rainwater is difficult to break through this defense line and extend inward, thereby avoiding the PCB from being dampened due to the rainwater intrusion.

[0024] In the design process of the controller, the complexity of the manufacturing process and the deformation problem of the upper cover in the manufacturing link need to be considered. Due to the limitation of the manufacturing process, it is difficult to ensure the absolute accuracy of the size of the upper cover during production, and the upper cover may be deformed to a certain extent, which will affect the sealing and performance of the whole product. Therefore, the second gap is designed to be larger than the first gap, thereby reserving the production error space and reducing the production difficulty. In addition, the second gap is less than or equal to 0.1mm, which can also prevent rainwater from entering the inside of the containing cavity.

[0025] According to another specific embodiment of the present application, the inner wall of the metal lower cover is provided with a connecting piece, the connecting piece is annular, the PCB board is arranged on the connecting piece and connected with the connecting piece, and the PCB board is grounded with the connecting piece.

[0026] By adopting the above technical scheme, the circuit on the PCB board will generate electromagnetic radiation during operation, and the grounding of the PCB board through the connecting piece can help reduce the emission of these electromagnetic radiations.

[0027] According to another specific embodiment of the present application, the upper cover comprises a plurality of stress parts, the plurality of stress parts are arranged on the outer wall of the upper cover in the circumferential direction, and the plurality of stress parts are used to be pressed to connect the upper cover and the metal lower cover.

[0028] By adopting the above technical scheme, since the first connector, the Ethernet connector and the second connector in the containing cavity all belong to fine parts, if the operator accidentally presses them during assembly, these connectors are extremely easy to be damaged. Therefore, a plurality of stress parts are arranged on the outer wall of the upper cover, which avoid the positions of the first connector, the Ethernet connector and the second connector. When the connection operation of the upper cover and the metal lower cover is performed, the operator can complete the operation by pressing the stress parts, so as to avoid damaging the fine connectors due to accidental touch.

[0029] According to another specific embodiment of the present application, the upper cover is made of plastic material.

[0030] By adopting the above technical scheme, the heat dissipation of the whole controller can be conducted out through the metal lower cover, without relying on the upper cover for heat dissipation. In this case, the upper cover can be made of plastic material, which has lower cost than metal material, and can meet the basic structure and protection requirements of the controller upper cover under the premise of not needing to bear the main heat dissipation function, while effectively saving the production cost.

[0031] According to another specific embodiment of the present application, the corners and the middle parts of the upper cover, the PCB board and the metal lower cover are respectively connected by a plurality of screws.

[0032] By the above technical solution, if the controller is circular or elliptical, the sealing connection can be realized by the buckle connection of the first side wall and the second side wall.

[0033] If the controller is polygonal, considering the deformation problem of the upper cover in the manufacturing link, the corners and the middle part of the upper cover, the PCB board and the metal lower cover may not guarantee good sealing, and gaps may occur, causing water vapor or dust from the outside to enter the controller. Therefore, by connecting multiple screws, the possible sealing problem can be compensated for, ensuring that the internal environment of the controller is not disturbed by external factors and maintaining its stable operation.

[0034] According to another specific embodiment of the present application, the corners of the metal lower cover are provided with a plurality of notches, and the plurality of notches are used to separate the upper cover and the metal lower cover through the plurality of notches.

[0035] By the above technical solution, when the upper cover and the metal lower cover are connected, a tight fitting state is formed between them. Since the gap reserved between them is very small, there is almost no space for operation, which makes it impossible to directly separate the upper cover and the metal lower cover under normal circumstances. If forced to separate, it is very likely to cause damage to both.

[0036] Therefore, a plurality of notches are provided at the corners of the metal lower cover. When the upper cover and the metal lower cover need to be separated, the operator can place tools or fingers in these notches and use the space and force point provided by the notches to gradually apply force, thereby safely and conveniently separating the upper cover and the metal lower cover, improving the operability during product maintenance and repair.

[0037] According to another specific embodiment of the present application, the metal lower cover includes a plurality of fixing portions, and the plurality of fixing portions are respectively arranged on the outer wall of the metal lower cover, and the plurality of fixing portions are used to be fixedly connected with the vehicle body.

[0068] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0069] Reference Figure 1 and Figure 2The embodiment of the present application provides a controller, the controller comprises a top cover 10, a PCB board 20 and a metal bottom cover 30 which are sequentially connected, the top cover 10 and the metal bottom cover 30 define a containing cavity 40, wherein the top cover 10, the PCB board 20 and the metal bottom cover 30 are rectangular respectively.

[0070] The PCB board 20 is located in the containing cavity 40, and the PCB board 20 comprises five first connectors 21 and two Ethernet connectors 22 which are arranged at intervals. Each first connector 21 comprises a first frame opening 211 and a first pin group 212, and the first frame opening 211 surrounds the first pin group 212. The PCB board 20 further comprises five second pin groups 231 which are arranged at intervals and are apart from the first connectors 21 and the Ethernet connectors 22.

[0071] The top cover 10 comprises four through holes 11, two through holes 11 surround one first connector 21 respectively, one through hole 11 surrounds two Ethernet connectors 22, and the other through hole 11 surrounds three first connectors 21. It should be noted that the number of the first connectors 21 and the Ethernet connectors 22 surrounded by each through hole 11 is not specifically limited in the embodiment of the present application, and the specific number is determined by the specific design scheme.

[0072] The top cover 10 further comprises four second frame openings 12, three second frame openings 12 surround one second pin group 231 respectively, and the other second frame opening 12 surrounds two second pin groups 231, and the second frame opening 12 surrounds the second pin group 231 to form a second connector 23.

[0073] The top cover 10 comprises three waterproof parts 13, and the waterproof parts 13 are arranged above the first connectors 21, the Ethernet connectors 22 and the second connectors 23 along the gravity direction G. Along the horizontal direction X, the top cover 10 comprises opposite first and second side walls 15 and 16, two ends of the waterproof parts 13 extend towards the first and second side walls 15 and 16 respectively, and the two ends of the waterproof parts 13 respectively exceed two ends of the first connectors 21, the Ethernet connectors 22 and the second connectors 23 to form a waterproof area 14, and the first connectors 21, the Ethernet connectors 22 and the second connectors 23 are located in the waterproof area 14.

[0074] Reference Figure 1 And Figure 2As the controller is placed in the vehicle along the gravity direction G, as shown in the dashed box A area, the A area has the waterproof part 13, the first connector 21, two second connectors 23, and the waterproof area 14. Along the gravity direction G, the waterproof part 13 in the A area is arranged above one first connector 21 and two second connectors 23. The first connector 21 is located on the left side of the two second connectors 23, and the two second connectors 23 are arranged at intervals along the gravity direction G. At this time, one end of the waterproof part 13 exceeds the left end of the first connector 21, and the other end of the waterproof part 13 exceeds the right end of the second connector 23, and the first connector 21 and the second connector 23 are both located in the waterproof area 14.

[0075] As shown in the dashed box B area, the B area has the waterproof part 13, the first connector 21, two Ethernet connectors 22, and the waterproof area 14. Along the gravity direction G, the waterproof part 13 in the B area is arranged above two Ethernet connectors 22 and one first connector 21. The two Ethernet connectors 22 and the first connector 21 are arranged at intervals along the gravity direction G, and at this time, the two ends of the waterproof part 13 exceed the two ends of the Ethernet connector 22, and also exceed the two ends of the first connector 21, and the two Ethernet connectors 22 and the first connector 21 are both located in the waterproof area 14.

[0076] As shown in the dashed box C area, the C area has the waterproof part 13, three first connectors 21, three second connectors 23, and the waterproof area 14. Along the gravity direction G, the waterproof part 13 in the C area is arranged above the three first connectors 21 and the three second connectors 23. Among them, two second connectors 23 are located on the left side and are arranged at intervals along the horizontal direction X, three first connectors 21 are located in the middle part and are arranged in sequence along the horizontal direction X, and one second connector 23 is located on the rightmost side and above the three first connectors 21. At this time, one end of the waterproof part 13 exceeds the left end of the second connector 23 located on the leftmost side, and the other end of the waterproof part 13 exceeds the right end of the second connector 23 located on the rightmost side, and the three first connectors 21 and the three second connectors 23 are both located in the waterproof area 14.

[0077] It should be noted that the number of first connectors 21, Ethernet connectors 22, and second connectors 23 covered by each waterproof part 13 is not specifically limited in the embodiments of the present application, and the number of first connectors 21, Ethernet connectors 22, and second connectors 23 covered by each waterproof part 13 is determined by the specific design scheme.

[0078] With the above technical solution, the controller is placed in the vehicle along the gravity direction G. In heavy rain weather conditions, rainwater may enter the first connector 21, the second connector 23 and the Ethernet connector 22 along the outer surface of the upper cover 10 along the gravity direction G, causing damage to the controller. Therefore, the waterproof part 13 is arranged above the first connector 21, the second connector 23 and the Ethernet connector 22. When rainwater falls, the rainwater will naturally flow along the surface of the waterproof part 13 due to the shielding of the waterproof part 13, and finally flow to the two ends of the waterproof part 13 and then drip. And because the two ends of the waterproof part 13 exceed the two ends of the first connector 21, the Ethernet connector 22 and the second connector 23, and at this time the first connector 21, the Ethernet connector 22 and the second connector 23 are in the waterproof area 14, they are prevented from being soaked in rainwater, thereby preventing the first connector 21, the Ethernet connector 22 and the second connector 23 from being damaged and malfunctioning.

[0079] In addition, the technical solution realizes the function of the central computing controller through the upper cover 10, the PCB board 20 including the Ethernet connector 22 and the metal lower cover 30. The metal lower cover 30 can meet the EMC requirement. The central computing controller will generate electromagnetic radiation during operation, and may also be subject to external electromagnetic interference. If not effectively shielded, these electromagnetic radiations may interfere with the normal operation of other electronic devices, affecting the overall performance and safety of the vehicle. In addition, external electromagnetic interference may also cause the central computing controller to malfunction, data errors and other problems. The metal lower cover 30 has good electrical conductivity and magnetic permeability, which can effectively block and reflect electromagnetic radiation, thereby protecting the electronic components inside the central computing controller from electromagnetic interference and ensuring its stable and reliable operation.

[0080] The PCB board 20 has multiple modules to meet the operation requirements of the central computing controller, such as the CCV module and the HPC module. The metal lower cover 30 not only plays a certain mechanical protection role to prevent the controller from being physically damaged, but also ensures the heat dissipation requirements of multiple modules in the controller.

[0081] It should be noted that the shapes of the upper cover 10, the PCB board 20 and the metal lower cover 30 are not specifically limited in the embodiments of the present application. For example, in other possible implementations, the shapes of the upper cover 10, the PCB board 20 and the metal lower cover 30 can be square, circular, etc. respectively, as long as the shapes of the upper cover 10, the PCB board 20 and the metal lower cover 30 are the same.

[0082] It should be noted that the number of the first connectors 21 included in the PCB 20 is not limited in the embodiments of the present application, for example, in other possible embodiments, the number of the first connectors 21 included in the PCB 20 can be four, six, seven, etc. The number of the Ethernet connectors 22 included in the PCB 20 is not limited in the embodiments of the present application, for example, in other possible embodiments, the number of the Ethernet connectors 22 included in the PCB 20 can be three, four, etc. The number of the second pin groups 231 included in the PCB 20 is not limited in the embodiments of the present application, for example, in other possible embodiments, the number of the second pin groups 231 included in the PCB 20 can be four, six, seven, etc.

[0083] It should be noted that the number of the through holes 11 included in the upper cover 10 is not limited in the embodiments of the present application, for example, in other possible embodiments, the number of the through holes 11 included in the upper cover 10 can be five, six, seven, etc. The number of the second frame openings 12 included in the upper cover 10 is not limited in the embodiments of the present application, for example, in other possible embodiments, the number of the second frame openings 12 included in the upper cover 10 can be five, six, seven, etc.

[0084] In some possible embodiments, referring to Figure 1 and Figure 2 The first pin group 212 includes a plurality of first pins 2121, and each first pin 2121 has a thickness less than 0.64 mm. Each second pin group 231 includes a plurality of second pins 2311, and each second pin 2311 has a thickness greater than or equal to 0.64 mm.

[0085] With the above technical solutions, for the first pins 2121 with a thickness less than 0.64 mm, the first pins 2121 have a small volume and a soft texture as a whole, and therefore, the first connector 21 (which can be referred to as a miniaturized connector) containing the first pins 2121 can be purchased from a supplier based on the manufacturing difficulty. For the second pins 2311 with a thickness greater than or equal to 0.64 mm, the second pins 2311 have a larger volume than the first pins 2121, and the structure of the second pins 2311 is relatively harder, thereby reducing the manufacturing difficulty. Therefore, the second pin groups 231 are directly connected to the PCB 20, and the second frame openings 12 of the second connector 23 are integrated with the upper cover 10, so as to correspondingly reduce the volume of the second connector 23, thereby enabling a plurality of second pin groups 231 to be placed on the PCB 20 to form a plurality of second connectors 23. In this way, the purchasing cost is reduced, and the demand for multiple connectors is met, thereby realizing the domain control function module of the controller.

[0086] Therefore, in combination with the foregoing, the controller in the technical solution can integrate a central computing controller and a vehicle body domain controller, thereby meeting the needs of multiple connectors while reducing costs.

[0087] In some possible implementation manners, with reference to Figure 1 and Figure 2 The waterproof part 13 at least includes an arc-shaped section 131, and the waterproof part 13 can further include a vertical section 132. The two ends of the arc-shaped section 131 are respectively connected with the vertical section 132.

[0088] With the technical solution, the positions of the first connector 21, the Ethernet connector 22, and the second connector 23 are random. For example, the first connector 21 and the second connector 23 can be arranged along the horizontal direction X as shown in the A area, or two Ethernet connectors 22 and one first connector 21 can be arranged along the gravity direction G as shown in the B area.

[0089] With reference to the B area, when two Ethernet connectors 22 and one first connector 21 are arranged along the gravity direction G, the waterproof area 14 in which they are located has a length along the horizontal direction X that is less than a length along the gravity direction G. In this case, when raindrops fall downward from the two ends of the waterproof part 13, because the waterproof area 14 has a limited coverage range along the horizontal direction X, the raindrops can cross the defense line of the waterproof area 14 and enter the first connector 21 located below. To avoid damage to the first connector 21 and ensure normal operation of the first connector 21, the vertical section 132 is provided as a secondary waterproof measure. The vertical section 132 can effectively intercept the raindrops falling from the two ends of the waterproof part 13, prevent the raindrops from further penetrating into the area where the first connector 21 is located, and thus provide more reliable waterproof protection for the first connector 21.

[0090] In some possible implementation manners, with reference to Figure 2 to Figure 4 The upper cover 10 includes a first inner wall 17, and the first inner wall 17 includes a first part 171 and a second part 172 that are connected. In a direction perpendicular to the PCB 20, the first part 171 is located above the second part 172, and the thickness of the first part 171 is greater than the thickness of the second part 172. The metal lower cover 30 includes a second side wall 31, the second part 172 surrounds the second side wall 31, and the second part 172 is snap-connected with the second side wall 31. The second part 172 includes a plurality of snap hooks 1721 arranged at intervals, and the second side wall 31 includes a plurality of snap blocks 313 arranged at intervals, and the snap hooks 1721 and the snap blocks 313 are snap-connected in a corresponding manner.

[0091] According to the technical scheme, the second part 172 is buckled with the second side wall 31 to realize the sealing of the upper cover 10 and the metal lower cover 30. The second part 172 surrounds and is buckled with the second side wall 31, that is, the first side wall 16 covers the second side wall 31, so that the impurities such as water vapor from the outside are effectively prevented from entering the internal part of the containing cavity 40, the PCB 20 inside the controller is protected from the influence of external environmental factors, and the stable and reliable operation of the controller is ensured.

[0092] According to another specific embodiment of the present application, with reference to Figure 2 to Figure 3B , the first gap 311 is between the second part 172 and the second side wall 31, the second gap 312 is between the end of the first part 171 and the end of the second side wall 31 in the direction perpendicular to the PCB 20, the first gap 311 is smaller than the second gap 312, and the second gap 312 is less than or equal to 0.1 mm.

[0093] According to the technical scheme, the controller is placed along the gravity direction G, and at this time, the first gap 311 extends along the horizontal direction X. When the rainwater flows toward the first gap 311 under the action of gravity, an effective barrier is formed because the first gap 311 is less than 0.1 mm. The rainwater is difficult to break through this line of defense and extend inward under the influence of surface tension and other factors, so it cannot enter the internal part of the containing cavity 40, avoiding the PCB 20 from being dampened due to the rainwater intrusion.

[0094] In the design process of the controller, the complexity of the manufacturing process and the possible deformation of the upper cover 10 in the manufacturing process need to be considered. Due to the limitation of the manufacturing process, it is difficult to ensure the absolute accuracy of the size of the upper cover 10 during the production of the upper cover 10, and the upper cover 10 may be deformed to a certain extent, which will affect the sealing and performance of the entire product. Therefore, the second gap 312 is designed to be larger than the first gap 311, thereby reserving the production error space and reducing the production difficulty. In addition, the second gap 312 is less than or equal to 0.1 mm, which can also prevent rainwater from entering the internal part of the containing cavity 40.

[0095] It should be noted that the length of the first gap 311 is not specifically limited in the embodiments of the present application, for example, in other possible embodiments, the length of the first gap 311 can be 0.03 mm, 0.04 mm, 0.05 mm, etc. The length of the second gap 312 is not specifically limited in the embodiments of the present application, for example, in other possible embodiments, the length of the second gap 312 can be 0.05 mm, 0.06 mm, 0.1 mm, etc., as long as the second gap 312 is larger than the first gap 311 and less than or equal to 0.1 mm.

[0096] In some possible embodiments, with reference to Figure 1 and Figure 2The inner wall 32 of the metal lower cover 30 is provided with a connecting piece 321 in the form of a ring, the PCB 20 is arranged on the connecting piece 321 and connected with the connecting piece 321, and the PCB 20 is grounded with the connecting piece 321.

[0097] With the above technical solution, the circuit on the PCB 20 generates electromagnetic radiation during operation, and the grounding of the PCB 20 through the connecting piece 321 can help reduce the emission of the electromagnetic radiation.

[0098] In some possible embodiments, with reference to Figure 1 and Figure 2 The upper cover 10 includes a plurality of force receiving portions 18, the force receiving portions 18 include two vertical structures, and the plurality of force receiving portions 18 are arranged on the outer wall of the upper cover 10 in the circumferential direction, and the plurality of force receiving portions 18 are used to be pressed to connect the upper cover 10 with the metal lower cover 30.

[0099] With the above technical solution, since the first connector 21, the Ethernet connector 22 and the second connector 23 in the accommodating cavity 40 are all fine components, they are easily damaged by being pressed by the operator during assembly. Therefore, a plurality of force receiving portions 18 are arranged on the outer wall of the upper cover 10, which avoid the positions of the first connector 21, the Ethernet connector 22 and the second connector 23. When connecting the upper cover 10 with the metal lower cover 30, the operator can complete the operation by pressing the force receiving portions 18, so as to avoid damaging the fine connectors due to accidental touch.

[0100] It should be noted that the number of the force receiving portions 18 included in the upper cover 10 is not specifically limited in the embodiments of the present application, for example, in other possible embodiments, the number of the force receiving portions 18 included in the upper cover 10 can be nine, ten, eleven, etc.

[0101] In some possible embodiments, the upper cover 10 is made of plastic material.

[0102] With the above technical solution, the heat dissipation of the whole controller can be conducted out through the metal lower cover 30, and the upper cover 10 does not need to rely on the upper cover 10 to dissipate heat. In this case, the upper cover 10 can be made of plastic material, which has lower cost than metal material, and under the premise of not needing to bear the main heat dissipation function, can meet the basic structure and protection requirements of the controller upper cover 10, while effectively saving production cost.

[0103] It should be noted that the material of the upper cover 10 is not specifically limited in the embodiments of the present application, for example, in other possible embodiments, the material of the upper cover 10 can be polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc.

[0104] In some possible implementation manners, referring to Figure 1 and Figure 2 corners and middle portions of the upper cover 10, the PCB board 20 and the metal lower cover 30 are connected by a plurality of screws (not shown in the figure) respectively.

[0105] With the technical solution, if the controller is circular or elliptical, the sealing connection can be realized by the snap connection of the first side wall 16 and the second side wall 31.

[0106] If the controller is polygonal, considering the deformation problem of the upper cover 10 in the manufacturing process, the corners and middle portions of the upper cover 10, the PCB board 20 and the metal lower cover 30 cannot guarantee good sealing, and gaps are likely to appear, causing the water vapor or dust in the outside to enter the inside of the controller. Therefore, the sealing deficiency problem can be compensated by the plurality of screws, so as to ensure that the internal environment of the controller is not disturbed by external factors and maintain stable operation.

[0107] In some possible implementation manners, referring to Figure 1 and Figure 2 corners of the metal lower cover 30 are provided with two notches 33, and the two notches 33 are used to disassemble the upper cover 10 and the metal lower cover 30 through the two notches 33.

[0108] With the technical solution, after the upper cover 10 and the metal lower cover 30 are connected, a close fitting state is formed between the two. Since the gap reserved between the two is very small, there is almost no space for operation, which makes it impossible to directly separate the upper cover 10 and the metal lower cover 30 under normal circumstances. If the two are forcibly separated, they are likely to be damaged.

[0109] Therefore, a plurality of notches 33 are arranged at the corners of the metal lower cover 30. When the upper cover 10 and the metal lower cover 30 need to be disassembled, the operator can place tools or fingers at these notches 33, and use the space and force point provided by the notches 33 to gradually apply force, so as to safely and conveniently disassemble the upper cover 10 and the metal lower cover 30, and improve the operability in the product maintenance and repair process.

[0110] It should be noted that the number of notches 33 included in the metal lower cover 30 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the number of notches 33 included in the metal lower cover 30 can be four, five, etc.

[0111] In some possible implementation manners, referring to Figure 1 and Figure 2The metal lower cover 30 comprises three fixing portions 34, which are respectively arranged on the outer wall of the metal lower cover 30 and are used for fixedly connecting with the vehicle body.

[0112] It should be noted that the number of the fixing portions 34 comprised by the metal lower cover 30 is not specifically limited in the embodiments of the present application, for example, in other possible embodiments, the number of the fixing portions 34 comprised by the metal lower cover 30 can be four, five, etc.

[0113] Although the present application has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood that the above description is intended to be illustrative only and not limiting of the application as it is being defined by the appended claims. Various changes in form and details of the application can be made by those skilled in the art without departing from the spirit and scope of the application.
