[0038] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0039] See Figure 1 、 Figure 2 and Figure 3, a control unit provided by an embodiment of the present application includes a connector 30, a valve body 20 and a driving member 10, wherein the connector 30 is electrically connected to the driving member 10, and the driving member 10 is transmission-connected to the valve body 20. The connector 30 is electrically connected to the control chip of the vehicle, and the control chip of the vehicle receives data from sensors at various locations of the vehicle and transmits the data to the connector 30. After receiving the data, the connector 30 analyzes the data and controls the driving member 10 to act according to the results of the analysis, thereby controlling the valve body 20 to be in different states through the driving member 10, and the medium flowing through the valve body 20 can switch the components of the vehicle to different states according to the different states of the valve body 20.

[0040] Taking the control unit controlling the air suspension of the vehicle as an example, after the connector 30 receives data from the road condition sensor and the vehicle height sensor, the sensor controls the action of the driver 10 based on the road condition and the vehicle height, and the driver 10 switches the state of the valve body 20, so that the air suspension is in a compressed, extended or maintained state, thereby adjusting the ground clearance of the vehicle body, increasing the stability of the vehicle body and the passability of complex road conditions.

[0041] It should be noted that, in addition to being used to control the air suspension, the control unit can also control other components of the vehicle, such as the rear wing, air conditioning, etc. The drive member 10 can be a motor, or an air pump, etc., which is not limited here.

[0042] The connector 30 includes a shell 31, a plug 32 and a circuit board (not shown in the figure). The plug 32 and the circuit board are both arranged in the shell 31. The plug 32 is used to connect to the main control chip of the vehicle and transmit the received data to the circuit board. The circuit board is connected to the driver 10 to control the driver 10 according to the data received by the plug 32, thereby controlling the action of the driver 10.

[0043] Among them, a plug terminal 33 is provided on the plug 32, and a crimping hole is provided on the circuit board. The plug terminal 33 is crimped into the crimping hole, so that the circuit board and the plug 32 are connected to each other through the cooperation of the plug terminal 33 and the crimping hole. After crimping, the plug terminal 33 fits tightly with the inner wall of the crimping hole. Even under the condition of vibration, the plug terminal 33 is not easy to fall out of the crimping hole. In this way, the connection between the circuit board and the plug 32 can be made tighter, the vibration resistance of the control unit is improved, and the normal operation of the control unit is ensured.

[0044] Specifically, the plug terminal 33 is a fisheye terminal, and the head size of the fisheye terminal is larger than the diameter of the crimping hole. After the fisheye terminal is crimped in the crimping hole under the action of external force, the head of the fisheye terminal will expand in the crimping hole, so that the head of the fisheye terminal can fit tightly with the inner wall of the crimping hole, thereby improving the connection strength between the plug terminal 33 and the crimping hole.

[0045] In some embodiments of the present application, refer to Figure 4 and Figure 5 , a plurality of supporting bosses 34 are provided on the housing 31. All the supporting bosses 34 are arranged around the periphery of the circuit board and are all abutted against one side of the circuit board, so as to support one side of the circuit board through the plurality of supporting bosses 34.

[0046] Furthermore, the housing 31 further includes a plurality of limiting buckles 35. All the limiting buckles 35 are arranged around the periphery of the circuit board and are all abutted against the other opposite side of the circuit board. In this way, the periphery of the circuit board is fixed between all the supporting bosses 34 and all the limiting buckles 35, effectively improving the installation strength of the circuit board on the housing 31. At the same time, the positions of the circuit board can also be limited by the plurality of limiting buckles 35 and supporting bosses 34, ensuring the assembly accuracy of the circuit board.

[0047] In some embodiments of the present application, a press is required for the crimping of the crimping holes of the circuit board and the plug terminals 33. To facilitate the operation of the press, the housing 31 is provided with an installation hole part and an opening 37 communicating with the installation space 36. The plug terminals 33 and the circuit board are both arranged in the installation space 36. During actual use, the press can press the circuit board onto the plug terminals 33 through the opening 37. The crimped circuit board and the plug terminals 33 do not require subsequent welding processes, resulting in more reliable contact and simpler technology.

[0048] In some embodiments, in addition to the plug terminals 33 being provided on the plug 32, a plurality of bottom terminals 46 are also provided inside the housing 31. The circuit board has a plurality of crimping holes, and a part of the plurality of bottom terminals 46 are crimped into the crimping holes on the circuit board to balance the force on the circuit board.

[0049] In some embodiments, the connector 30 is further provided with a plurality of coil terminal holes 47 inside the housing 31. The coil terminals of the vehicle can be directly pressed into the coil terminal holes 47 through an external tooling, so as to reduce the assembly difficulty of the connector 30 in the later stage.

[0050] During actual use, since the control unit is usually installed outside the vehicle, it will cause the control unit to be in direct contact with the external environment. The splashing water, water ingress, a large amount of dust, oil stains and the change of environmental temperature during the vehicle's driving will all affect the operation of the circuit board. For this reason, in some embodiments of the present application, refer to Figure 6 , the connector 30 further includes a cover plate 38. The cover plate 38 is installed on the housing 31 and seals the opening 37, so that the circuit board and the plug terminals 33 are both in a sealed environment, thereby reducing the influence of the external environment on the circuit board.

[0051] Among them, when the cover 38 is installed on the shell 31, sealant is needed to fill the gap between the cover 38 and the surface of the shell 31 to prevent moisture and dust from entering the installation space 36 through the gap between the cover 38 and the shell 31, thereby causing damage to the circuit board. However, if the sealant is filled directly between the cover 38 and the shell 31, the gap between the cover 38 and the shell 31 will be too small, resulting in the sealant being unable to enter the gap.

[0052] To this end, a plurality of protrusions 39 are provided on the surface of the shell 31 around the opening 37, and all the protrusions 39 are in contact with the cover plate 38, so that there is a gap between the cover plate 38 and the surface of the shell 31, and the gap is filled with sealant, so that the gap between the cover plate 38 and the surface of the shell 31 is increased by the protrusions 39, so that the sealant can smoothly enter the gap between the cover plate 38 and the shell 31, thereby better filling the gap between the cover plate 38 and the shell 31 and improving the sealing effect between the shell 31 and the cover plate 38.

[0053] In some embodiments, in order to install the cover plate 38 on the shell 31, a plurality of mounting holes 41 are provided on the cover plate 38, and the plurality of mounting holes 41 are arranged at intervals around the circumferential side wall of the cover plate 38. A plurality of mounting buckles 40 are provided on the shell 31, and the plurality of mounting buckles 40 are arranged at intervals on the circumferential side wall of the shell 31, and each mounting buckle 40 corresponds to one of the mounting holes 41, and the mounting buckle 40 can be snapped into the corresponding mounting hole 41, so that the cover plate 38 is installed on the shell 31.

[0054] It should be noted that in other embodiments, the cover plate 38 may be provided with a mounting buckle 40 , and the housing 31 may be provided with a mounting hole 41 , which is not limited here.

[0055] Specifically in some embodiments, a heat dissipation boss 42 is protruding from the surface of the cover plate 38 on one side away from the installation space 36, so as to increase the contact area between the cover plate 38 and the air through the heat dissipation boss 42, thereby improving the heat exchange efficiency between the cover plate 38 and the air, and further improving the heat dissipation effect of the connector 30. Among them, the cover plate 38 is made of metal material to further improve the heat exchange efficiency between the cover plate 38 and the air, and improve the heat dissipation efficiency of the connector 30.

[0056] Specifically, in some embodiments, a grounding contact 43 is protrudingly provided on the surface of the cover plate 38 on one side away from the installation space 36. The grounding contact 43 contacts metal parts such as the longitudinal beam of the vehicle to introduce the current on the cover plate 38 into the vehicle, thereby achieving the effect of grounding the cover plate 38.

[0057] In some embodiments of the present application, in order to make the overall volume of the control unit more compact and save the occupied area of the control unit, the valve body 20 is installed on the housing 31 and is hermetically connected to the housing 31. The housing 31 can not only support the valve body 20, but also form a seal on the surface of the valve body 20 through the housing 31, so that there is no need to additionally seal the valve body 20, achieving the effects of reducing the number of parts, reducing part control and process costs.

[0058] Specifically, a valve body sealing ring 48 is provided on the surface of the housing 31. When the valve body 20 is installed on the surface of the housing 31, the gap between the valve body 20 and the housing 31 can be filled through the valve body sealing ring 48, so that a sealed connection can be formed between the housing 31 and the valve body 20.

[0059] In some embodiments, since the driving member 10 needs to be electrically connected to the circuit board to receive signals from the circuit board, for this reason, the connector 30 further includes a conductive member 44. The conductive member 44 is installed on the housing 31 and is electrically connected to the circuit board. A connection hole 21 is provided on the valve body 20, and the conductive member 44 passes through the connection hole 21 and is electrically connected to the driving member 10. That is to say, through the connection hole 21, a space for the conductive member 44 to pass through can be formed inside the valve body 20, so that the connector 30 can be electrically connected to the driving member 10 located on the other side of the valve body 20.

[0060] Specifically in some embodiments, one end of the conductive member 44 extends into the installation space 36 and is provided with a conductive terminal 50. The conductive terminal 50 of the conductive member 44 is crimped in one of the crimping holes on the circuit board. Through the cooperation of the conductive terminal 50 and the crimping hole, while the conductive member 44 is electrically connected to the circuit board, the connection strength between the conductive member 44 and the circuit board can be ensured, and the anti-vibration ability of the control unit can be improved. Optionally, the conductive terminal 50 is also a fish-eye terminal.

[0061] In some embodiments of the present application, in order to fix the control unit on the vehicle, a threaded hole 49 is further provided on the circumferential side wall of the housing 31. The threaded hole 49 and the housing 31 are integrally formed by injection molding, which not only ensures the overall strength of the housing 31, but also makes it easier for the housing 31 to be assembled with other components of the vehicle.

[0062] The present application also provides a vehicle, including the control unit in any of the above embodiments. Since in the above control unit, even when vibrating, the plug terminal 33 is not easily detached from the crimping hole, the anti-vibration performance of the control unit is improved, ensuring the normal operation of the control unit. Therefore, the vehicle equipped with the above control unit can also have a good anti-vibration effect, improving the service life of the vehicle.

[0063] In some embodiments, the vehicle further includes an air suspension, and the control unit is configured to control the air suspension to be in a compressed, extended, or maintained state, thereby adjusting the ground clearance of the vehicle body and enhancing the stability of the vehicle body and its passability on complex road conditions.

[0064] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0065] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
