[0048] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0051] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] like Figure 1-Figure 5As shown, this embodiment provides a car controller housing structure, including a housing 1, a moisture-proof box 2, a locking system 3 and a driving system 4. A slot 11 is provided on the housing 1. The moisture-proof box 2 is movably inserted in the slot 11 for storing a moisture-proof agent. It can be understood by those skilled in the art that an air hole needs to be provided on the moisture-proof box 2 so that the air in the inner cavity of the housing 1 can be in contact with the moisture-proof agent in the moisture-proof box 2. The locking system 3 is provided on the housing 1, and the locking system 3 includes a first motor 31, a transmission assembly 32 and a limit device 33. The limit device 33 has a first working position and a second working position. The first motor 31 can drive the limit device 33 to move between the first working position and the second working position through the transmission assembly 32. When the limit device 33 is in the first working position, the limit device 33 can lock the moisture-proof box 2 in the slot 11. When the limit device 33 is in the second working position, the moisture-proof box 2 can move along the depth direction of the slot 11. The driving system 4 is disposed on the housing 1 . When the limiting device 33 is located at the second working position, the driving system 4 can drive the moisture-proof box 2 to move out of the housing 1 along the depth direction of the slot 11 .

[0053] The automobile controller housing structure provided in this embodiment can drive the transmission assembly 32 to drive the limit device 33 to move between the first working position and the second working position through the first motor 31, thereby realizing the locking and unlocking of the moisture-proof box 2, and when the moisture-proof box 2 is in the unlocked state, the moisture-proof box 2 can be driven by the drive system 4 to move outward from the housing 1 along the depth direction of the slot 11, so that the moisture-proof box 2 can be taken out very conveniently, thereby improving the replacement efficiency of the moisture-proof box 2.

[0054] Furthermore, if Figure 1 and Figure 2As shown, the limit device 33 includes a left limit device 331 and a right limit device 332, and the transmission assembly 32 includes a screw rod 321, a first connecting rod 322 and a second connecting rod 323. The screw rod 321 is rotatably arranged on the housing 1. Specifically, in this embodiment, the outer side of the top plate of the housing 1 is provided with two support rings 14 arranged at intervals along the length direction of the housing 1, and the two ends of the screw rod 321 are respectively rotatably inserted into the two support rings 14. The screw rod 321 is located at one side of the slot 11 and extends along the length direction of the slot 11. The screw rod 321 includes a first screw segment 3211 and a second screw segment 3212 that are coaxially arranged and fixedly connected. One end of the first screw segment 3211 away from the second screw segment 3212 is transmission-connected to the first motor 31, and the first screw segment 3211 and the second screw segment 3212 have opposite thread rotation directions. One end of the first connecting rod 322 is screwed to the first screw segment 3211, and the other end extends to the outside of the first end in the length direction of the slot 11. A left stopper 331 is provided at one end of the first connecting rod 322 away from the first screw segment 3211. One end of the second connecting rod 323 is screwed to the second screw segment 3212, and the other end extends to the outside of the second end in the length direction of the slot 11. A right stopper 332 is provided at one end of the second connecting rod 323 away from the second screw segment 3212. In this embodiment, the first connecting rod 322 and the second connecting rod 323 are both perpendicular to the screw 321. The first motor 31 can drive the screw 321 to rotate, so that the first connecting rod 322 and the second connecting rod 323 drive the left stopper 331 and the right stopper 332 to move closer to and away from each other along the extension direction of the screw 321, so that the stopper 33 moves between the first working position and the second working position. Among them, the position where the distance between the left limit device 331 and the right limit device 332 is close and both are in contact with the moisture-proof box 2 is the first working position, and the position where the distance between the left limit device 331 and the right limit device 332 is far and neither is in contact with the moisture-proof box 2 is the second working position.

[0055] Furthermore, if Figure 1 and Figure 2As shown, the left limit device 331 and the right limit device 332 both include a first frame 3301, an elastic member 3302 and a pressing assembly 3303. The first frame 3301 of the left limit device 331 is fixedly disposed at one end of the first connecting rod 322 away from the screw rod 321, and the first frame 3301 of the right limit device 332 is fixedly disposed at one end of the second connecting rod 323 away from the screw rod 321. The elastic member 3302 is disposed in the first frame 3301, and a first opening is disposed on a side of the first frame 3301 facing the slot 11. The first end of the elastic member 3302 is fixedly connected to the first frame 3301, and the second end extends toward the first opening in a direction parallel to the screw rod 321. The pressing assembly 3303 is fixedly disposed at the second end of the elastic member 3302, and is exposed to the first frame 3301 through the first opening. When the limiting device 33 is located at the first working position, the pressing component 3303 presses against the end surface of the moisture-proof box 2, thereby locking the moisture-proof box 2 in the slot 11. When the limiting device 33 is located at the second working position, the pressing component 3303 is out of contact with the moisture-proof box 2 and is located outside the path of the moisture-proof box 2, thereby releasing the lock on the moisture-proof box 2. In this embodiment, the elastic member 3302 is a spring.

[0056] Furthermore, if Figure 1 and Figure 2 As shown, the pressing assembly 3303 includes a second frame 33031 and a roller 33032. The second frame 33031 is fixedly arranged at the second end of the elastic member 3302. The roller 33032 is rotatably arranged in the second frame 33031, and a second opening is arranged at one end of the second frame 33031 away from the elastic member 3302, and the roller 33032 is exposed to the second frame 33031 through the second opening. The housing 1 is provided with a slide 12 corresponding to the pressing assembly 3303, and the slide 12 extends along the length direction of the slot 11. The side walls of the slide 12 are provided with limit grooves extending along the extension direction of the slot 11, and the two ends of the rotating shaft of the roller 33032 are respectively inserted into the limit grooves on the side walls of the slide 12.

[0057] When the moisture-proof box 2 needs to be locked, the first motor 31 drives the screw rod 321 to rotate along the first direction. Since the two ends of the roller 33032 shaft are inserted into the limiting grooves on both sides of the slide groove 12, under the limiting effect of the limiting grooves on the shaft, the roller 33032 can only rotate around its own shaft relative to the shell 1, and cannot rotate around the axis of the first connecting rod 322 with the first connecting rod 322, nor can it rotate around the axis of the second connecting rod 323 with the second connecting rod 323. As a result, when the first motor 31 drives the screw rod 321 to rotate along the first direction, the first connecting rod 322 and the second connecting rod 323 move along the extension direction of the slide groove 12, that is, the length direction of the slot 11 under the drive of the screw rod 321. Since the thread rotation directions of the first screw segment 3211 and the second screw segment 3212 of the screw rod 321 are opposite, when the screw 321 is rotated along the first direction, the two pressing assemblies 3303 can approach each other until the rollers 33032 of the two pressing assemblies 3303 are in contact with the moisture-proof box 2. When it is necessary to unlock the moisture-proof box 2 for replacing it, the first motor 31 can be used to drive the screw 321 to rotate in a second direction opposite to the first direction, so that the two pressing components 3303 move away from each other until the two pressing components 3303 are out of contact with the moisture-proof box 2. At this time, the moisture-proof box 2 is in an unlocked state.

[0058] Furthermore, if Figure 1 and Figure 2 As shown, both sides of the first frame 3301 along the extending direction of the slot body are provided with limiting rods 33011, and are respectively inserted into the limiting grooves on both sides of the slide groove 12. By providing the limiting rods 33011 on both sides of the first frame 3301, when the screw 321 rotates, the limiting rods 33011 on both sides of the first frame 3301 cooperate with the rotating shaft of the roller 33032 to limit the first connecting rod 322 and the second connecting rod 323, so as to prevent the first connecting rod 322 and the second connecting rod 323 from rotating when the screw 321 rotates, and ensure that the rotation of the screw 321 can be effectively converted into the sliding of the left limiting device 331 and the right limiting device 332 along the slide groove 12, thereby realizing the locking and unlocking of the moisture-proof box 2. Those skilled in the art will appreciate that in order for the roller 330321 of the roller 33032 and the limit rod 33011 to achieve the function of limiting the rotation of the first connecting rod 322 and the second connecting rod 323 around their own axes, the limit rod 33011 on the left limit device 331 and the roller 330321 of the roller 33032 cannot be colinear with the axis of the first connecting rod 322, and the limit rod 33011 on the right limit device 332 and the roller 330321 of the roller 33032 cannot be colinear with the axis of the second connecting rod 323.

[0059] Alternatively, if Figure 1 and Figure 2As shown, locking grooves 22 are provided at both ends of the end surface of the moisture-proof box 2 in the length direction, and rubber pads 23 are provided in the locking grooves 22. When the limiting device 33 is located at the first working position, the rollers 33032 of the left limiting device 331 and the rollers 33032 of the right limiting device 332 respectively abut against the rubber pads 23 at both ends of the length direction of the moisture-proof box 2. The provision of the rubber pads 23 can increase the friction between the moisture-proof box 2 and the rollers 33032, and can play a buffering role to reduce the shaking of the moisture-proof box 2 when the vehicle is running.

[0060] Furthermore, if Figure 1 and Figure 2 As shown, the rubber pad 23 is provided with anti-slip stripes to further increase the friction between the rubber pad 23 and the roller 33032 .

[0061] Alternatively, if Figure 3-Figure 5 As shown, the driving system 4 includes two driving mechanisms 41, and the two driving mechanisms 41 are respectively arranged on both sides of the moisture-proof box 2, so that when the moisture-proof box 2 is driven to move out of the slot 11 by the driving device, the moisture-proof box 2 is subjected to more uniform force, thereby avoiding the moisture-proof box 2 from getting stuck due to deflection during the outward movement.

[0062] Furthermore, if Figure 1-Figure 5 As shown, the housing 1 is provided with an annular groove 13 surrounding the slot 11, the driving mechanism 41 is provided at the bottom of the annular groove 13, and the moisture-proof box 2 is provided with an abutment portion 21 surrounding the moisture-proof box 2, and the abutment portion 21 extends into the annular groove 13. When the moisture-proof box 2 needs to be removed, the driving force of the driving mechanism 41 acts on the abutment portion 21 on the moisture-proof box 2 to drive the moisture-proof box 2 to move out of the housing 1.

[0063] Furthermore, if Figure 3 and Figure 4 As shown, the driving mechanism 41 includes an electric cylinder 411 and a block 412. The electric cylinder 411 is arranged at the bottom of the annular groove 13. The block 412 is arranged on the telescopic rod of the electric cylinder 411, and the electric cylinder 411 can drive the block 412 to move along the depth direction of the slot 11. When it is necessary to remove the moisture-proof box 2, the piston rod of the electric cylinder 411 is used to drive the block 412 to extend, and the block 412 abuts against the abutment portion 21 of the moisture-proof box 2, and pushes the abutment portion 21 outward from the shell 1, thereby driving the moisture-proof box 2 to move outward from the shell 1. When it is necessary to install the moisture-proof box 2, the block 412 is first retracted by contracting the piston of the electric cylinder 411, and then the moisture-proof box 2 is inserted into the slot 11 to avoid the block 412 from obstructing the installation of the moisture-proof box 2.

[0064] Furthermore, if Figure 3-Figure 5As shown, the bottom of the annular groove 13 is provided with a mounting groove 15 corresponding to the driving mechanism 41 one by one, and the lower part of the driving mechanism 41 is arranged in the corresponding mounting groove 15. That is, the electric cylinder 411 is installed in the mounting groove 15.

[0065] Alternatively, if Figure 1 As shown, the automobile controller housing structure provided in this embodiment also includes a heat dissipation mechanism 5, which is arranged on the housing 1. The heat dissipation mechanism 5 includes a heat dissipation fan 51. The housing 1 is provided with a heat dissipation hole 16 connecting the inside and outside of the housing 1, and the heat dissipation fan 51 is arranged in the heat dissipation hole 16. The heat dissipation mechanism 5 also includes a second motor, and the heat dissipation fan 51 is connected to the second motor by transmission. The heat dissipation fan 51 is driven by the second motor to rotate, so as to achieve heat dissipation in the housing 1. In this embodiment, the heat dissipation mechanism 5 also includes a dustproof net 52 arranged in the heat dissipation hole 16, and the dustproof net 52 is arranged outside the heat dissipation fan 51.

[0066] In this embodiment, if Figure 1 As shown, there are two moisture-proof boxes 2, and the locking system 3 and the driving system 4 are arranged one by one with the moisture-proof boxes 2. There are two heat dissipation holes 16, and the two heat dissipation holes 16 and the two plug holes are arranged on the top plate of the housing 1, and the two heat dissipation holes 16 are arranged between the two plug holes.

[0067] Alternatively, if Figure 1-Figure 4 As shown, the automobile controller housing structure provided in this embodiment also includes a sealing ring 6, which is arranged between the moisture-proof box 2 and the groove wall of the slot 11, and surrounds the moisture-proof box 2 to seal the gap between the moisture-proof box 2 and the groove wall of the slot 11, thereby improving the sealing performance at the slot 11.

[0068] Optionally, the automobile controller housing structure provided in this embodiment also includes a first control button and a second control button arranged on the housing 1. Those skilled in the art can understand that a controller is arranged in the housing 1, and the first control button is electrically connected to the first motor 31 via the controller, and the second control button is electrically connected to the electric cylinder 411 via the controller. The controller is electrically connected to the second motor, and the controller can control the opening and closing and the speed of the cooling fan 51 according to the temperature in the housing 1. The first control button controls the opening and closing and the forward and reverse rotation of the first motor 31 through the controller, that is, controls the locking system 3 to lock and unlock the moisture-proof box 2, and the second control button controls the extension and retraction of the electric cylinder 411.

[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
