Description

Technical Field

[0001] This utility model relates to a multi-level safety protection device for a vehicle body controller, and in particular to a multi-level safety protection device for a vehicle body controller applied in the field of automotive electronic safety. Background Technology

[0002] As a core component of the automotive electronic system, the body controller undertakes many key functions such as door control, lighting adjustment, and wiper control. Its stable operation is directly related to the overall performance of the vehicle and the safety of passengers.

[0003] Currently, in order to ensure that the vehicle body controller works stably in the complex operating environment of the vehicle (frequent vibration, possible intrusion of dust and moisture, etc.), it needs to be protected. Usually, protective shells, protective covers and other structures are used to encapsulate the controller body and block adverse external influences. However, existing vehicle body controller protection devices have defects in the connection and fixation of the protective cover and the protective shell. Most of them use traditional bolt fixing methods. The continuous vibration generated by vehicle driving can easily loosen the bolts, causing the protective cover to fall off and exposing the controller body, which cannot effectively protect it. Moreover, the bolt removal and installation must be done one by one, which is cumbersome, consumes manpower and time, and brings inconvenience to the daily inspection and maintenance of the controller body. It is difficult to meet the dual requirements of protection reliability and operation convenience in actual use. In view of this, this utility model is proposed. Summary of the Invention

[0004] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that most existing vehicle body controller protective devices use traditional bolts to fix the protective cover and the protective shell. The vibration of the vehicle during driving can easily cause the bolts to loosen and the protective cover to fall off, exposing the controller body and causing the protection to fail.

[0005] To address the aforementioned problems, this utility model provides a multi-level safety protection device for a vehicle body controller, comprising a protective shell, and further comprising: a controller body detachably connected to the protective shell; a protective cover detachably connected to the protective shell; and multiple arc-shaped protrusions of plug-in rods evenly distributed around the outer circumference of the outer wall, fixedly connected to the protective cover. The protective shell has plug-in holes corresponding to the plug-in rods, and the plug-in rods have sliding grooves. A slide rod is slidably connected within the sliding groove, and a rotating ring is rotatably connected to the lower end of the slide rod. Multiple fixing blocks are integrally formed on the outer wall of the rotating ring. Multiple fixing grooves corresponding to the fixing blocks are formed at the lower end of the sliding groove. A tension spring is provided within the sliding groove, with one end of the tension spring fixedly connected to the inner wall of the sliding groove and the other end fixedly connected to the slide rod.

[0006] In the multi-level safety protection device of the above-mentioned vehicle body controller, a locking mechanism consisting of a plug rod and a plug hole, a fixing block and a fixing groove is used. Combined with the continuous tension of the tension spring, the fixing block is firmly locked into the fixing groove when the vehicle vibrates. The arc-shaped protrusion enhances the stability of the plug connection, prevents the protective cover from loosening and falling off, ensures the protection of the controller body, and reduces the risk of exposure and damage.

[0007] As a further improvement to this application, it also includes multiple fixing bolts, through which the controller body is detachably connected to the protective shell.

[0008] As a further improvement to this application, a shock-absorbing pad is provided on the inner wall of the lower end of the protective shell, and the shock-absorbing pad is in contact with the lower end surface of the controller body.

[0009] As a further improvement of this application, a sealing frame is fixedly connected to the lower end face of the protective cover, and a sealing gasket is provided on the outer wall of the sealing frame, with the sealing gasket fitting against the inner wall of the protective shell.

[0010] As another improvement of this application, an airbag is embedded in the outer wall of the sealing frame, the airbag is located between the sealing frame and the sealing gasket, and an air supply pipe connected to the airbag is provided on the protective cover, and a valve switch is provided on the air supply pipe.

[0011] As a further improvement to this application, multiple sealing grooves are equidistantly provided on the inner wall of the protective shell. When the airbag inflates, it can compress the sealing gasket to fit tightly against the protective shell while deforming it, so that it is embedded in the sealing groove to form multiple seals.

[0012] In summary, this application utilizes a locking mechanism consisting of a plug rod and a plug hole, a fixing block and a fixing groove, and a continuous tension spring. When the vehicle vibrates, the fixing block is firmly locked into the fixing groove, and the arc-shaped protrusion enhances the stability of the plug connection, preventing the protective cover from loosening and falling off, ensuring the protection of the controller body and reducing the risk of exposure and damage. Installation is simple: just plug in, rotate, and loosen the handle. Disassembly is the reverse process, eliminating the need to remove and install multiple bolts one by one. This simplifies the process, saves manpower and time, and makes daily inspection and maintenance of the controller easier. After the protective cover is installed, the airbag is inflated through the air supply pipe. The inflated airbag compresses the sealing gasket and fits more tightly against the inner wall of the protective shell, improving the sealing performance at the connection. In conjunction with the sealing groove on the inner wall of the protective shell, the expansion of the airbag causes the sealing gasket to embed into the groove, forming multiple seals, which further enhances the sealing performance and effectively prevents external dust, moisture, and foreign objects from entering, protecting the controller body from contamination and moisture damage.

[0015] The first embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0016] Implementation

[0017] Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 The diagram illustrates a multi-level safety protection device for a vehicle body controller, comprising a protective shell 1, and further comprising: a controller body 2, detachably connected to the protective shell 1; a protective cover 101, detachably connected to the protective shell 1; and multiple arc-shaped protrusions 402 evenly distributed around the outer circumference of the protective cover 101, wherein the protective shell 1 has insertion holes 4 corresponding to the insertion rods 402, the insertion rods 402 have sliding grooves 403, a sliding rod 404 is slidably connected in the sliding grooves 403, a rotating ring 405 is rotatably connected to the lower end of the sliding rod 404, multiple fixing blocks 406 are integrally formed on the outer wall of the rotating ring 405, multiple fixing grooves 401 corresponding to the fixing blocks 406 are provided at the lower end of the sliding grooves 403, and a tension spring 407 is provided in the sliding grooves 403, one end of the tension spring 407 being fixedly connected to the inner wall of the sliding grooves 403, and the other end being fixedly connected to the sliding rod 404.

[0018] In use, first install the controller body 2 into the protective shell 1. Then, the operator holds the protective cover 101 and closes it onto the protective shell 1. While closing, align the insertion rod 402 on the protective cover 101 with the insertion hole 4 on the protective shell 1 and insert it smoothly. During the process, keep the protective cover 101 roughly parallel to the protective shell 1 to ensure that the insertion rod 402 is smoothly inserted into the insertion hole 4 until the lower end face of the protective cover 101 contacts and adheres to the upper end face of the protective shell 1, thus sealing the protective shell 1. It should be noted that at this time, the fixing block 406 on the rotating ring 405 coincides with the arc-shaped protrusion on the insertion rod 402. After closing, the operator pulls the sliding rod 404 downward using the handle fixedly connected to the lower end of the sliding rod 404, stretching the tension spring 407. As the sliding rod 404 moves downward, the rotating ring 405 on it moves synchronously until the rotating ring 405 is removed from the insertion hole 4. Then rotate the rotating ring 405 so that the fixing block 406 on the rotating ring 405 coincides with the fixing groove 401 and intersects with the arc protrusion on the plug rod 402. Then slowly release the handle. At this time, the stretched tension spring 407 releases its elastic potential energy, pulls the slide rod 404 to drive the rotating ring 405 to move upward and reset, so that the fixing block 406 is inserted into the fixing groove 401, realizing mechanical locking and completing the installation of the protective cover 101. Compared with the traditional bolt fixing, this structure uses the cooperation between the plug rod 402 and the plug hole 4, as well as the locking mechanism composed of the fixing block 406 and the fixing groove 401. In the vehicle vibration environment, the tension spring 407 continuously provides tension, so that the fixing block 406 is firmly stuck in the fixing groove 401. The arc protrusion enhances the plugging stability and effectively prevents the protective cover 101 from loosening or falling off due to vibration, ensuring the protection effect on the controller body 2 inside the protective shell 1 and reducing the risk of exposure and damage to the controller body 2. When it is necessary to disassemble the protective cover 101, pull down the slide bar 404 with the handle to stretch the tension spring 407 again. The slide bar 404 moves down and drives the rotating ring 405 to move down, so that the fixing block 406 is pulled out of the fixing groove 401. Then rotate the rotating ring 405 to make the fixing block 406 displace the fixing groove 401 and return to the state of coinciding with the arc protrusion on the plug rod 402, so as to prepare for the plug rod 402 to be pulled out. Then hold the protective cover 101 with both hands and pull it outward to pull the plug rod 402 out of the plug hole 4. The protective cover 101 is separated from the protective shell 1 so that the controller body 2 inside the protective shell 1 can be inspected, maintained and other operations can be performed. In summary, the installation of the protective cover 101 can be completed with simple operations such as plugging, rotating, and loosening the handle. Disassembly is done by simply reversing the operation. Compared with the traditional method of disassembling and assembling multiple bolts one by one, the steps are simplified, saving time and manpower, thus facilitating the daily inspection and maintenance of the controller body 2.

[0019] Figure 1, Figure 4 As shown, it also includes multiple fixing bolts 202, and the controller body 2 is detachably connected to the protective shell 1 through the multiple fixing bolts 202; By utilizing the interlocking threads of the fixing bolt 202 and the threaded holes on the protective shell 1, the axial force generated by tightening the fixing bolt 202 presses the controller body 2 tightly onto the protective shell 1. Relying on the friction and preload of the threaded connection, a detachable fixed connection between the controller body 2 and the protective shell 1 is achieved, restricting the movement of the controller body 2 within the protective shell 1. The multiple fixing bolts 202 are distributed at different positions on the controller body 2. Tightening them in a reasonable order (such as diagonally) can ensure that the clamping force on the controller body 2 is evenly distributed, avoiding excessive local force that could cause deformation or damage to the mounting surface of the controller body 2 or the protective shell 1, and ensuring the stability of the connection. In summary, the fastening effect of multiple fixing bolts 202 provides a stable and reliable fixing effect for the controller body 2, making it less likely for the controller body 2 to shift or shake due to vibrations or bumps during vehicle operation within the protective shell 1. This ensures the stability of its relative position with the protective shell 1 and other related components, thereby facilitating the normal operation of the controller body 2.

[0020] Figure 1 , Figure 4 As shown, a shock-absorbing pad 201 is provided on the inner wall of the lower end of the protective shell 1, and the shock-absorbing pad 201 is in contact with the lower end surface of the controller body 2; When the vehicle vibrates while driving, the vibration is transmitted from the protective shell 1 to the shock absorber 201. The shock absorber 201 uses the properties of its own elastic material to convert the vibration energy into the energy of elastic deformation. Through molecular friction and other actions inside the material, some energy is consumed, thereby reducing the amplitude and intensity of the vibration transmitted to the controller body 2, playing a buffering and shock-absorbing effect, and protecting the controller body 2 from excessive vibration damage.

[0021] Figure 1 , Figure 2 As shown, a sealing frame 3 is fixedly connected to the lower end face of the protective cover 101, and a sealing gasket 301 is provided on the outer wall of the sealing frame 3. The sealing gasket 301 is in contact with the inner wall of the protective shell 1. When performing the installation operation of the protective cover 101 (such as the alignment, insertion, and locking steps described above), the sealing frame 3 moves down with the protective cover 101 and gradually inserts into the interior of the protective shell 1. The sealing gasket 301 first contacts the inner wall of the protective shell 1. As the protective cover 101 moves closer to the protective shell 1 and is finally installed in place, the sealing gasket 301 is squeezed by the inner wall of the protective shell 1 and the sealing frame 3, and undergoes elastic deformation to fill the gap between the two, achieving a tight seal. This creates a sealing barrier between the protective cover 101 and the protective shell 1, effectively preventing external dust, moisture, foreign objects, etc. from entering the interior of the protective shell 1, and protecting the controller body 2 from pollution, moisture, and other damage.

[0022] Figure 1 , Figure 7 As shown, an airbag 302 is embedded in the outer wall of the sealing frame 3. The airbag 302 is located between the sealing frame 3 and the sealing gasket 301. An air supply pipe 304 connected to the airbag 302 is provided on the protective cover 101. A valve switch is provided on the air supply pipe 304. First, following the installation steps described above, install the protective cover 101 onto the protective shell 1, insert the sealing frame 3 into the protective shell 1, and initially fit the sealing gasket 301 against the inner wall of the protective shell 1. Then, open the valve switch and use an air pump or other equipment to inflate the airbag 302 through the air supply pipe 304, causing the airbag 302 to expand. The expanded airbag 302 compresses the sealing gasket 301 and fits more tightly against the inner wall of the protective shell 1, improving the sealing performance at the connection between the protective cover 101 and the protective shell 1. Then, stop inflating, close the valve switch, and keep the airbag 302 in an inflated state.

[0023] Figure 7 As shown, multiple sealing grooves 303 are equidistantly provided on the inner wall of the protective shell 1. When the airbag 302 expands, it can squeeze the sealing gasket 301 to fit tightly against the protective shell 1 while deforming it, so that it is embedded in the sealing groove 303 to form multiple seals. When air is inflated into the airbag 302, the inflated airbag 302 can not only compress the sealing gasket 301 to fit more tightly against the inner wall of the protective shell 1, but also cause the sealing gasket 301 to undergo elastic deformation and gradually embed into the sealing groove 303 on the inner wall of the protective shell 1, forming multiple seals, which further improves the sealing performance at the connection between the protective cover 101 and the protective shell 1. Then, the inflation is stopped, the valve is closed, and the airbag 302 is kept in an inflated state.

[0024] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
