Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of controllers, in particular to a tamper-proof structure, an automobile controller and a tamper-proof mounting method thereof. BACKGROUND

[0002] In today's highly developed global communication era, information security is particularly important. For product designers and manufacturers, the protection of product information is also a top priority, which involves the secrecy of product key technologies, ensures that the company's research and development investment can bring long-term and effective benefits, and occupies a favorable position in the fierce market competition.

[0003] Among the protection measures of product information technology (specifically, such as automobile controllers, roadside device controllers, etc.), the tamper-proof technology is a typical and practical key measure. It prevents the physical structure of the product from being violently disassembled in an unauthorized manner, or records unauthorized disassembly, which can maximize the protection of product internal information, or check whether the product has been disassembled and tampered with during the after-sales maintenance process, which is also a guarantee for the interests of the enterprise.

[0004] The existing controller (specifically, such as an automobile controller or a roadside device controller) is usually composed of a shell and a cover plate, a control circuit board is arranged in the shell, and the cover plate is sealed on the opening of the shell through a tamper-proof structure. A commonly used tamper-proof structure is to use a tamper-proof screw with a customized screw cap to tightly connect the cover plate to the opening of the shell. In actual application, it is found that when the controller fails, some non-maintenance personnel with low professional level like to specially process or purchase a corresponding screwdriver to disassemble the tamper-proof screw, and then disassemble the cover plate to maintain the internal controller. Since they are not professional maintenance personnel, sometimes they not only cannot repair the controller well, but also may cause secondary damage to the controller. At this time, if the controller with secondary damage is handed over to a professional maintenance personnel for maintenance, it will undoubtedly greatly increase the maintenance difficulty of the maintenance personnel. Moreover, the non-maintenance personnel can also twist the tamper-proof screw again without leaving traces after disassembling it, which cannot record the tamper-proof action and is easy to cause subsequent security disputes. Therefore, some controller manufacturers also use a second tamper-proof structure, that is, a tear-resistant sticker is added to the outside of the controller (the joint of the shell and the cover plate). When the tear-resistant sticker is torn, it leaves a record of "tampering". SUMMARY

[0005] Therefore, the present application aims to solve the technical problem of overcoming the defects of the poor anti-disassembly effect and the inability to accurately record the disassembly action of the anti-disassembly structure applied to the connection between the cover plate and the shell of the controller in the prior art, thereby providing an anti-disassembly structure, a car controller and an anti-disassembly installation method thereof.

[0006] According to the anti-disassembly structure provided by the first aspect of the present application, the anti-disassembly structure is applied to the connection between the cover plate and the shell of the controller, and the anti-disassembly structure comprises:

[0007] A first mounting block is arranged at the edge of one end of the cover plate along the height direction towards the shell, the first mounting block is arranged parallel to the length direction, and a first blind hole is arranged along the length direction in one end of the first mounting block away from the center of the cover plate,

[0008] A first bolt is slidingly inserted into the first blind hole along the length direction, a first elastic member is arranged between the first bolt and the surrounding wall of the first blind hole; the first bolt has a storage state hidden in the first blind hole, and a locking state in which one end of the first bolt extends out of the first blind hole;

[0009] A first pin hole is arranged in the shell towards one side of the first bolt, the first pin hole is matched with the first bolt, the first pin hole is arranged parallel to the length direction and does not penetrate through the side wall of the shell;

[0010] A second locking part is arranged at the edge of one end of the cover plate along the height direction towards the shell, the second locking part and the first mounting block are arranged on different sides of the cover plate, respectively;

[0011] A second locking groove is arranged in the shell towards one side of the second locking part, the second locking groove is used for embedding and clamping the second locking block.

[0012] According to the anti-disassembly structure, at least the following technical effects are achieved: 1. By arranging the first mounting block and the second locking portion at the edges of the two different sides of the end surface of the cover plate facing the shell, respectively, the first blind hole of the first mounting block is slidably inserted with the first bolt, and the first elastic member is arranged between the first bolt and the surrounding wall of the first blind hole. During the assembly of the cover plate at the opening of the shell, the cover plate is first inclined to form an angle with the horizontal plane, then the second locking portion is inserted into the inside of the shell and is embedded and connected in the second locking groove (realizing the limiting connection of one side of the cover plate and the corresponding side of the shell), and then the cover plate is rotated around the connection between the second locking portion and the second locking groove. When the first bolt is about to contact the inner wall of the shell, the first bolt is pressed to compress the first elastic member into the first blind hole (into the storage state), so that the inner wall of the shell abuts against the end of the first bolt away from the first elastic member, and exerts a top force on the first elastic member. When the cover plate is rotated to the position where the first bolt is aligned with the first pin hole, the top force on the first bolt for compressing the first elastic member disappears, so that the first bolt is pushed into the first pin hole under the elastic restoring force of the first elastic member (into the locking state), realizing the limiting connection of the two different sides of the cover plate and the corresponding two sides of the shell. External force cannot directly open the cover plate, and the anti-disassembly connection positions of the cover plate and the shell are hidden inside the shell and not exposed, thereby realizing the anti-disassembly installation of the cover plate and the shell by high-reliability pure physical means. After the controller product is assembled and completed, it is difficult for non-factory personnel to accurately understand the two anti-disassembly connection positions of the cover plate and the shell, thereby increasing the difficulty of violent disassembly for non-factory maintenance personnel, and the factory maintenance personnel can perform professional positioning disassembly operation according to the disassembly design position of the controller product. If non-maintenance personnel forcibly choose to violently disassemble the cover plate and the shell, the degree of physical partial damage to the connection between the cover plate and the shell is basically different from that when the factory maintenance personnel normally disassemble the cover plate and the shell, thereby avoiding subsequent security disputes. 2. Because the two anti-disassembly connection positions of the cover plate and the shell are hidden inside the shell and not exposed, whether it is violent disassembly by non-factory maintenance personnel or professional positioning disassembly by factory maintenance personnel, a permanent disassembly mark record is left on the outer surface of the controller, so that whether the controller has been disassembled can be accurately identified from the appearance of the controller.

[0019] According to the second aspect of the present application, an automobile controller is provided, comprising a cover plate, a shell, and an anti-disassembly structure arranged at the connection between the cover plate and the shell, the anti-disassembly structure adopts the anti-disassembly structure provided in the first aspect.

[0020] According to the automobile controller provided by the present application, at least the following technical effects are achieved:

[0021] 1. By setting the first mounting block and the second locking part at the edges of two different sides of the end face of the cover plate towards the shell respectively, slidingly inserting the first plug into the first blind hole of the first mounting block, and setting the first elastic member between the first plug and the surrounding wall of the first blind hole; in the process of assembling the cover plate at the opening of the shell, first tilt the cover plate to form an angle with the horizontal plane, then extend the second locking part into the interior of the shell and fit and connect in the second locking slot (realize the limiting connection of one side of the cover plate and the corresponding side of the shell), then rotate the cover plate around the connection between the second locking part and the second locking slot, when the first plug is about to contact the inner wall of the shell, press the first plug to compress the first elastic member into the first blind hole (enter the locking state), so that the inner wall of the shell and the end of the first plug away from the first elastic member abut, and apply a top force to the first plug to compress the first elastic member; when the cover plate is rotated to the position where the first plug aligns with the first pin hole, the top force applied to the first plug to compress the first elastic member disappears, so that the first plug is pushed into the first pin hole under the action of the elastic restoring force of the first elastic member (entering the locking state), realizing the limiting connection of the two different sides of the cover plate and the corresponding two sides of the shell, external force cannot directly open the cover plate, and the anti-disassembly connection positions of the cover plate and the shell are hidden in the shell and not exposed, thereby realizing the anti-disassembly installation of the cover plate and the shell by high reliability pure physical means; At the same time, after the automobile controller product is assembled and completed, it is difficult for non-original factory personnel to accurately understand the two anti-disassembly connection positions of the cover plate and the shell, thereby increasing the difficulty of violent disassembly for non-original factory maintenance personnel, while the original factory maintenance personnel can perform professional positioning disassembly operation according to the disassembly design position of the product; If non-maintenance personnel forcibly choose to violently disassemble the cover plate and the shell, the degree of physical partial damage to the connection between the cover plate and the shell is basically different from that when the original factory maintenance personnel normally disassemble the cover plate and the shell, thereby avoiding some subsequent guarantee disputes. 2. Because the anti-disassembly structure in the automobile controller hides the two anti-disassembly connection positions of the cover plate and the shell in the shell and does not expose them, whether it is violent disassembly by non-original factory maintenance personnel or professional positioning disassembly by original factory maintenance personnel, it will leave permanent disassembly marks on the surface of the automobile controller, so that whether the automobile controller has been disassembled can be accurately identified from the appearance of the automobile controller.

[0022] Preferably, a rubber ring for sealing is arranged at the joint of the cover plate and the shell;

[0026] According to the third aspect of the present application, a tamper-proof mounting method is provided, which is applied to the automobile controller provided in the second aspect, and the tamper-proof mounting method comprises the following steps:

[0027] The first elastic member is installed into the first blind hole, and then the first pin is slidingly inserted into the first blind hole and abuts against the first elastic member;

[0028] The cover plate is tilted to form an included angle with the horizontal plane, and then the second locking portion is embedded and clamped into the second locking groove;

[0029] The cover plate is rotated around the connection between the second locking portion and the second locking groove, the first pin is pressed to compress the first elastic member and hide it in the first blind hole, after the end of the first pin away from the first elastic member abuts against the inner wall of the shell, the pressing force applied to the first pin is removed, then the cover plate is rotated to the position where the first pin is aligned with the first pin hole, at this time, the first pin is extended out of the first blind hole under the elastic restoring force of the first elastic member and is inserted into the first pin hole, and the tamper-proof mounting is completed.

[0030] According to the tamper-proof mounting method, at least the following technical effects are achieved:

[0031] 1. By setting the first mounting block and the second locking part at the edges of two different sides of the end face of the cover plate towards the shell respectively, slidingly inserting the first bolt into the first blind hole of the first mounting block, and setting the first elastic member between the first bolt and the surrounding wall of the first blind hole; in the process of assembling the cover plate at the opening of the shell, first, the cover plate is inclined to form an angle with the horizontal plane, then the second locking part is inserted into the inside of the shell and is embedded and connected in the second locking groove (realizing the limiting connection of one side of the cover plate and the corresponding side of the shell), then the cover plate is rotated around the connection between the second locking part and the second locking groove, when the first bolt is about to contact the inner wall of the shell, the first elastic member is compressed by pressing the first bolt to be stored in the first blind hole (entering the locking state), so that the inner wall of the shell abuts against the end of the first bolt away from the first elastic member, and exerts a top force on the first elastic member; when the cover plate is rotated to the position where the first bolt is aligned with the first pin hole, the top force on the first bolt for compressing the first elastic member disappears, so that the first bolt is pushed into the first pin hole under the elastic restoring force of the first elastic member (entering the locking state), realizing the limiting connection of the two different sides of the cover plate and the corresponding two sides of the shell, and external force cannot directly open the cover plate, the whole anti-disassembly installation process does not need to rely on tools, and the installation is convenient and efficient.

[0032] 2. By hiding the two anti-disassembly connection positions between the cover plate and the shell inside the shell without exposure, the cover plate and the shell are installed by high-reliability pure physical means, at the same time, after the automobile controller product is assembled and completed at the factory, it is difficult for non-factory personnel to accurately understand the two anti-disassembly connection positions of the cover plate and the shell, increasing the difficulty of violent disassembly for non-factory maintenance personnel, while the factory maintenance personnel can perform professional positioning disassembly operation according to the disassembly design position of the product; if the non-maintenance personnel forcibly choose violent disassembly of the cover plate and the shell, the degree of physical partial damage to the connection part of the cover plate and the shell is basically different from that of the factory maintenance personnel when normally disassembling the cover plate and the shell, thereby avoiding some subsequent guarantee disputes. At the same time, because the two anti-disassembly connection positions of the cover plate and the shell are hidden inside the shell without exposure, whether it is violent disassembly of non-factory maintenance personnel or professional positioning disassembly of factory maintenance personnel, a permanent disassembly mark record is left on the surface of the automobile controller, so that whether the automobile controller has been disassembled can be accurately identified from the appearance of the automobile controller.

[0052] Embodiment one

[0053] As Figures 1 to 5 and Figure 7The anti-disassembly structure provided by the embodiment is applied to the connection between the cover plate 1 and the shell 2 of an automobile controller, and comprises a first mounting block 31 and a second locking portion 34 arranged at the edge of one end of the cover plate 1 along the height direction towards the shell 2, and a first pin hole 21 and a second locking groove 22 arranged on the inner wall of the shell 2, wherein the first mounting block 31 and the second locking portion 34 are arranged on different sides of the cover plate 1 respectively; the first mounting block 31 is arranged parallel to the length direction, and a first blind hole 311 is arranged in the end of the first mounting block 31 away from the center of the cover plate 1 along the length direction; a first plug pin 32 is slidingly inserted into the first blind hole 311 along the length direction, and a first elastic member 33 is arranged between the first plug pin 32 and the surrounding wall of the first blind hole 311; the first plug pin 32 has a storage state hidden in the first blind hole 311, and a locking state in which one end of the first plug pin 32 extends out of the first blind hole 311; the first pin hole 21 is arranged on the side of the shell 2 towards the first plug pin 32, and the first pin hole 21 is matched with the first plug pin 32, wherein the first pin hole 21 is arranged parallel to the length direction and does not penetrate through the side wall of the shell 2; the second locking groove 22 is arranged on the side of the shell 2 towards the second locking portion 34, and the second locking groove 22 is used for embedding and clamping the second locking block. It can be understood that the height direction and the length direction shown in the embodiment refer to the height direction and the length direction shown in Figure 1

[0054] ​Compared with the prior art, the anti-disassembly structure of the embodiment of the present application is characterized in that: first mounting blocks 31 and second locking portions 34 are respectively arranged at the edges of two different sides of the end face of the cover plate 1 towards the shell 2, a first blind hole 311 of the first mounting block 31 is slidably inserted with a first bolt 32, and a first elastic member 33 is arranged between the first bolt 32 and the surrounding wall of the first blind hole 311; during the assembly of the cover plate 1 at the opening of the shell 2, the cover plate 1 is first inclined to form an angle with the horizontal plane, then the second locking portion 34 is inserted into the inside of the shell 2 and clamped in the second locking groove 22 (realizing the limiting connection of one side of the cover plate 1 with the corresponding side of the shell 2), and then the cover plate 1 is rotated around the connection between the second locking portion 34 and the second locking groove 22, when the first bolt 32 is about to contact the inner wall of the shell 2, the first bolt 32 is pressed to compress the first elastic member 33 into the first blind hole 311 (entering the locking state), so that the inner wall of the shell 2 abuts against the end of the first bolt 32 away from the first elastic member 33, and exerts a top force on the first bolt 32 to compress the first elastic member 33; when the cover plate 1 is rotated to the position where the first bolt 32 is aligned with the first pin hole 21, the top force exerted on the first bolt 32 to compress the first elastic member 33 disappears, so that the first bolt 32 is pushed into the first pin hole 21 under the elastic restoring force of the first elastic member 33 (entering the locking state), realizing the limiting connection of the two different sides of the cover plate 1 with the corresponding two sides of the shell 2, an external force cannot directly open the cover plate 1, and the two anti-disassembly connection positions of the cover plate 1 and the shell 2 are hidden in the shell 2 and not exposed, thereby realizing the anti-disassembly installation of the cover plate 1 and the shell 2 by a high-reliability pure physical means; at the same time, after the automobile controller product is assembled and completed at the factory, it is difficult for non-factory personnel to accurately know the two anti-disassembly connection positions of the cover plate 1 and the shell 2, thereby increasing the difficulty of violent disassembly for non-factory maintenance personnel, and the factory maintenance personnel can perform professional positioning disassembly work according to the disassembly design position of the product; if the non-maintenance personnel forcibly choose to violently disassemble the cover plate 1 and the shell 2, the degree of physical partial damage to the connection position of the cover plate 1 and the shell 2 is basically different from that when the factory maintenance personnel normally disassemble the cover plate 1 and the shell 2, thereby avoiding some subsequent guarantee disputes. At the same time, because the two anti-disassembly connection positions of the cover plate 1 and the shell 2 of the anti-disassembly structure of the embodiment are hidden in the shell 2 and not exposed, whether it is violent disassembly of non-factory maintenance personnel or professional positioning disassembly of factory maintenance personnel, a permanent disassembly mark record is left on the outer surface of the automobile controller, so that whether the automobile controller has been disassembled can be accurately identified from the appearance of the automobile controller.

[0055] The first mounting block 31 and the second locking portion 34 are arranged on different sides of the cover plate 1, and in specific applications, the first mounting block 31 can be arranged on the left side of the cover plate 1 along the length direction, and the second locking portion 34 can be arranged on the right side of the cover plate 1 along the length direction, or arranged on the front side of the cover plate 1 along the width direction, or arranged on the rear side of the cover plate 1 along the width direction; or the first mounting block 31 can be arranged on the right side of the cover plate 1 along the length direction, and the second locking portion 34 can be arranged on the left side of the cover plate 1 along the length direction, or arranged on the front side of the cover plate 1 along the width direction, or arranged on the rear side of the cover plate 1 along the width direction. The above arrangement can achieve the positioning connection between the two different sides of the cover plate 1 and the corresponding two sides of the shell 2, and external force cannot directly open the cover plate 1, thereby achieving the anti-disassembly installation of the cover plate 1 and the shell 2 by a pure physical means with high reliability. In order to ensure the anti-disassembly locking effect between the cover plate 1 and the shell 2, and further improve the difficulty of forcibly disassembling the shell 2 and the cover plate 1 of the automobile controller by non-original maintenance personnel, as shown in Figure 2 In the embodiment, the second locking portion 34 and the first mounting block 31 are arranged on the two sides of the cover plate 1 along the length direction. It can be understood that the left side and the right side along the length direction and the front side and the rear side along the width direction in the embodiment are described based on the perspective shown in Figure 2 It can be understood that the left side and the right side along the length direction and the front side and the rear side along the width direction in the embodiment are described based on the perspective shown in Figure 2 It can be understood that the left side and the right side along the length direction and the front side and the rear side along the width direction in the embodiment are described based on the perspective shown in

[0056] It can be understood that the above embodiment is only a description of the use scene of the anti-disassembly structure of the application on the automobile controller, and in specific applications, the use scene of the anti-disassembly structure of the application can be flexibly adjusted. For example, in other embodiments, the anti-disassembly structure of the application can be applied to the connection between the cover plate 1 and the shell 2 of a roadside equipment controller or other controllers with a cover plate 1 and a shell 2, and the same technical effects as above can also be achieved.

[0057] As shown in Figure 2 , Figure 5 and Figure 7 In some embodiments of the application, the second locking portion 34 includes a connecting plate 341 arranged on the cover plate 1, and a horizontal clamping jaw 342 is formed by folding the opposite lower end surface of the connecting plate 341 along the height direction, the horizontal clamping jaw 342 is perpendicular to the height direction and located on the side of the connecting plate 341 away from the center of the cover plate 1; the horizontal clamping jaw 342 is matched with the second locking groove 22. In the process of assembling the cover plate 1 at the opening of the shell 2, the connecting plate 341 transitions the connection between the horizontal clamping jaw 342 and the cover plate 1, so that the horizontal clamping jaw 342 can extend into the interior of the shell 2 even in a narrow space, and is embedded and clamped in the second locking groove 22, further improving the convenience of anti-disassembly installation.

[0058] In some embodiments of the present application, the second locking part 34 comprises a second mounting block arranged on the cover plate 1, a second blind hole is arranged in the length direction of the second mounting block on the end face of the second mounting block away from the center of the cover plate 1, a second latch is slidingly inserted into the second blind hole, a second elastic member is arranged between the second latch and the surrounding wall of the second blind hole, the second latch has a storage state hidden in the second blind hole and a locking state with one end extending out of the second blind hole; the second locking slot 22 is arranged as a second pin hole matched with the second latch. In the process of assembling the cover plate 1 at the opening of the shell 2, first place the cover plate 1 directly above the opening of the shell 2 (at this time the first latch 32 corresponds to the first pin hole 21 and the second latch corresponds to the second pin hole), then press the first latch 32 and the second latch into the first blind hole 311 and the second blind hole respectively, then press the cover plate 1 downward along the height direction relative to the shell 2, so that the inner walls of the two different sides of the shell 2 abut against the end of the first latch 32 away from the first elastic member 33 and the end of the second latch away from the second elastic member respectively, and the first latch 32 is subjected to a top force compressing the first elastic member 33 and the second latch is subjected to a top force compressing the second elastic member, when the cover plate 1 is pressed to the position where the first latch 32 aligns with the first pin hole 21 and the second latch aligns with the second pin hole, the top force applied to the first latch 32 and the second latch disappears, so that the first latch 32 and the second latch are pushed into the first pin hole 21 and the second pin hole respectively under the elastic restoring force of the first elastic member 33 and the second elastic member, realizing the limiting connection of the two different sides of the cover plate 1 with the corresponding two sides of the shell 2, and an external force cannot directly open the cover plate 1; when it is necessary to disassemble the cover plate 1, a drill bit is used to penetrate the first pin hole 21 and the second pin hole from the outside of the shell 2, so that the first latch 32 and the second latch can be taken out from the penetrated first pin hole 21 and the second pin hole respectively, and the cover plate 1 can be smoothly opened, further improving the reliability of the anti-disassembly installation of the cover plate 1 and the shell 2 by pure physical means. It can be understood that the first latch 32 and the second latch are located on the same straight line in the length direction, and the first pin hole 21 and the second pin hole are located on the same straight line in the length direction, to ensure that when the first latch 32 aligns with the first pin hole 21, the second latch also aligns with the second pin hole.

[0059] In order to keep the limiting connection force between the two different sides of the cover plate 1 and the corresponding two sides of the shell 2 the same, ensure that an external force cannot directly open the cover plate 1, and improve the convenience of assembling the anti-disassembly structure of the present embodiment, specifically, the first mounting block 31 and the second mounting block are arranged as the same component, and the first elastic member 33 and the second elastic member are arranged as the same elastic member.

[0060] Specifically, the first elastic member 33 is preferably a spring standard part for bulk purchase. In other embodiments, the first elastic member 33 can also be made of elastic materials such as spring steel and the like.

[0061] Specifically, the second elastic member is preferably a spring standard part for bulk purchase. In other embodiments, the second elastic member can also be made of elastic materials such as spring steel and the like.

[0062] As shown in Figure 1 , Figure 3 and Figure 6 , in some embodiments of the present application, the anti-tampering structure further comprises a first guide slope 23 arranged at the end surface of the shell 2 along the height direction towards the cover plate 1, the first guide slope 23 is located directly above the first pin hole 21 along the height direction, and the first guide slope 23 gradually inclines upward along the length direction towards the direction in which the first mounting block 31 deviates from the center of the cover plate 1. During the assembly of the cover plate 1 at the opening of the shell 2, when the cover plate 1 is flipped or pressed downward relative to the shell 2, the first guide slope 23 will push the first latch 32 to compress the first elastic member 33 and gradually hide into the first blind hole 311 to enter the storage state, achieving automatic entry into the storage state without the need for the operator to apply a pressing force to the first latch 32, and when the cover plate 1 is pressed down to the position where the first latch 32 aligns with the first pin hole 21, the upward force applied to the first latch 32 for compressing the first elastic member 33 disappears, so that the first latch 32 is pushed into the first pin hole 21 under the elastic restoring force of the first elastic member 33 to enter the locked state; achieving the limiting connection of the two different sides of the cover plate 1 with the corresponding two sides of the shell 2, and external force cannot directly open the cover plate 1. During the entire anti-tampering installation process, the operator does not need to use tools and the work intensity is small, and the anti-tampering installation efficiency is high.

[0063] In order to avoid the assembly path of the second locking part 34 during assembly of the cover plate 1, and to play a guiding role, to ensure that the second locking part 34 can be inserted into the interior of the shell 2 even in a relatively narrow space, and accurately embedded and clamped in the second locking groove 22, further improving the convenience of anti-tampering installation; as shown in Figure 4 , in some embodiments of the present application, the anti-tampering structure further comprises a second guide slope 24 arranged at the end surface of the shell 2 along the height direction towards the cover plate 1, the second guide slope 24 is located directly above the second locking groove 22 along the height direction, and the second guide slope 24 gradually inclines upward along the direction in which the second locking part 34 deviates from the center of the cover plate 1.

[0064] In specific applications, the cross-sectional shape of the first pin 32 can be selected according to actual requirements for preventing disassembly, for example, in other embodiments, the cross-sectional shape of the first pin 32 can be set as one of a circle, a rectangle, a square, or other irregular polygons.

[0065] As shown in Figures 4 to 7 some embodiments of the present application, the first pin hole 21 is provided with a third blind hole 25 at one end away from the center of the shell 2 in the length direction, the third blind hole 25 is arranged on the side wall of the shell 2, the third blind hole 25 is located on the same line as the first pin hole 21 in the length direction, and a partition 26 is arranged between the first pin hole 21 and the third blind hole 25. The third blind hole 25 is used to indicate the position of the first pin hole 21, when the cover plate 1 needs to be removed, the original manufacturer's maintenance personnel do not need to look up the design drawings of the product to find the position of the first pin hole 21, they only need to use the third blind hole 25 as a positioning hole, use a drill to drill through the partition 26 so that the first pin hole 21 is connected to the outside world, so as to take out the first pin 32 from the first pin hole 21, and then the cover plate 1 can be smoothly opened; at the same time, because the partition 26 has been drilled through, it has permanently marked that the automobile controller has been disassembled.

[0066] Embodiment two

[0067] As shown in Figures 1 to 7 the automobile controller provided in this embodiment includes a cover plate 1, a shell 2, and a disassembly prevention structure arranged at the connection between the cover plate 1 and the shell 2, the disassembly prevention structure adopts the disassembly prevention structure described in embodiment one.

[0068] Compared with the prior art, the automobile controller of the embodiment is provided with the first mounting block 31 and the second locking portion 34 at the edges of two different sides of the end face of the cover plate 1 towards the shell 2, the first blind hole 311 of the first mounting block 31 is slidably inserted with the first bolt 32, and the first elastic member 33 is arranged between the first bolt 32 and the surrounding wall of the first blind hole 311. During the assembly of the cover plate 1 at the opening of the shell 2, the cover plate 1 is first inclined to form an angle with the horizontal plane, then the second locking portion 34 is inserted into the inside of the shell 2 and clamped in the second locking groove 22 (to realize the limiting connection of one side of the cover plate 1 and the corresponding side of the shell 2), and then the cover plate 1 is rotated around the connection between the second locking portion 34 and the second locking groove 22. When the first bolt 32 is about to contact the inner wall of the shell 2, the first bolt 32 is pressed to compress the first elastic member 33 into the first blind hole 311 (to enter the locking state), so that the inner wall of the shell 2 abuts against the end of the first bolt 32 away from the first elastic member 33 and applies a top force to the first bolt 32 to compress the first elastic member 33. When the cover plate 1 is rotated to the position where the first bolt 32 is aligned with the first pin hole 21, the top force applied to the first bolt 32 to compress the first elastic member 33 disappears, so that the first bolt 32 is pushed into the first pin hole 21 under the elastic restoring force of the first elastic member 33 (to enter the locking state), realizing the limiting connection of the two different sides of the cover plate 1 and the corresponding two sides of the shell 2. An external force cannot directly open the cover plate 1, and the anti-disassembly connection positions of the cover plate 1 and the shell 2 are hidden in the shell 2 and not exposed, so that the cover plate 1 and the shell 2 are anti-disassembly mounted by a high-reliability pure physical means, and the automobile controller of the embodiment is anti-disassembly mounted. At the same time, after the automobile controller product is assembled and completed at the factory, it is difficult for non-factory personnel to accurately know the two anti-disassembly connection positions of the cover plate 1 and the shell 2, thereby increasing the difficulty of violent disassembly for non-factory maintenance personnel, and the factory maintenance personnel can perform professional positioning disassembly work according to the disassembly design position of the product. If a non-maintenance personnel forcibly chooses to violently disassemble the cover plate 1 and the shell 2, the degree of physical partial damage to the connection position of the cover plate 1 and the shell 2 is basically different from that when the factory maintenance personnel normally disassembles the cover plate 1 and the shell 2, thereby avoiding some subsequent guarantee disputes. At the same time, because the anti-disassembly structure in the automobile controller of the embodiment hides the two anti-disassembly connection positions of the cover plate 1 and the shell 2 in the shell 2 and does not expose them, whether violent disassembly by non-factory maintenance personnel or professional positioning disassembly by factory maintenance personnel, both leave permanent disassembly marks on the outer surface of the automobile controller, so that whether the automobile controller has been disassembled can be accurately identified from the appearance of the automobile controller.

[0069] It should be noted that after the professional positioning and removal operation of the disassembly design position between the cover plate 1 and the shell 2 of the automobile controller by the original factory maintenance personnel, although the anti-disassembly part is permanently damaged, it is limited to this local range. Therefore, it will not affect the normal use of the subsequent automobile controller product; but it can be easily identified from the appearance that the automobile controller has been disassembled.

[0070] In order to improve the sealing performance between the cover plate 1 and the shell 2, thereby improving the waterproof performance of the automobile controller, as shown in Figure 5 and Figure 6 In some embodiments of the present application, a rubber ring 4 for sealing is arranged at the joint of the cover plate 1 and the shell 2.

[0071] In order to further ensure the fastening of the connection between the cover plate 1 and the shell 2, as shown in Figures 1 to 4 In some embodiments of the present application, twelve through holes 11 are arranged on the cover plate 1 along the contour of the cover plate 1, the through holes 11 penetrate the cover plate 1 in the height direction, and the shell 2 is provided with a threaded hole 27 corresponding to each through hole 11 at one end face of the shell 2 facing the cover plate 1. After the first pin 32 is inserted into the first pin hole 21 and the second locking groove 22 is embedded and clamped in the second locking groove 22, twelve fastening screws 12 are selected to be screwed through the corresponding through holes 11 and the corresponding threaded holes 27, thereby further improving the fastening of the automobile controller assembly. At the same time, the original factory maintenance personnel can find the position of the first pin hole 21 by looking up the design drawing of the product, and use a drill bit to drill through the first pin hole 21, and then take out the first pin 32 from the first pin hole 21, so that the cover plate 1 can be easily opened. After the professional positioning and removal operation of the disassembly design position between the cover plate 1 and the shell 2 of the automobile controller, although the anti-disassembly part is permanently damaged, at this time, the first elastic member 33 and the first pin 32 are not needed, and the cover plate 1 and the cover plate 1 can be reconnected together only by the fastening screw 12. Therefore, it will not affect the normal use of the subsequent automobile controller product; but it can be easily identified from the appearance that the automobile controller has been disassembled. It should be noted that if the protection effect is considered to be enhanced on the basis of the normal use of the subsequently disassembled automobile controller, the channel for communication between the first pin 32 and the outside can be sealed by glue plugging, and the first pin 32 and the second locking part 34 can be used for anti-disassembly installation.

[0072] Specifically, the through hole 11 is provided as a countersunk hole, and a large diameter part of the countersunk hole is arranged at one end of the countersunk hole away from the shell 2, and the large diameter part of the countersunk hole is provided for embedding the nut of the fastening screw 12, so as to prevent the nut of the fastening screw 12 from being exposed on the surface of the cover plate 1, which not only easily scratches people, but also affects the appearance.

[0073] As Figure 1 Specifically, the automobile controller further comprises a circuit board 5 connected in the shell 2 through a second screw 51. By detachably connecting the circuit board 5 in the shell 2, when the circuit board 5 is damaged, the circuit board 5 can be detached for maintenance or replacement.

[0074] As Figure 1 In some embodiments of the present application, a plurality of communication interfaces 28 are arranged on the outer side wall of the shell 2, and the automobile controller is connected in communication with an external terminal through the communication interfaces 28. Specifically, the communication interfaces 28 are Ethernet interfaces, antenna interfaces, etc. It should be noted that, in the process of assembling the automobile controller, the circuit board 5 and the communication interfaces 28 are first mounted on the shell 2, and then the shell 2 and the cover plate 1 are anti-disassembly mounted.

[0075] In order to further simplify the assembly process of the automobile controller and improve the installation efficiency, in some embodiments of the present application, the first mounting block 31 and the cover plate 1 are integrally formed, and the second locking portion 34 and the cover plate 1 are integrally formed.

[0076] In some embodiments of the present application, the cover plate 1 and the shell 2 are made of aluminum alloy material, and the first bolt 32 and the first elastic member 33 are made of steel material. Because the cover plate 1 and the shell 2 are usually made by pressure casting, in order to facilitate batch pressure casting, the cover plate 1 and the shell 2 are made of aluminum alloy material; because the size of the first bolt 32 and the first elastic member 33 is not easy to be too large and thick, but the strength thereof needs to meet the anti-disassembly requirement, the first bolt 32 and the first elastic member 33 are made of steel material.

[0077] Embodiment three

[0078] As Figures 1 to 7 The anti-disassembly mounting method provided in the present embodiment is applied to anti-disassembly mounting of the automobile controller of embodiment two, and comprises the following steps:

[0079] The first elastic member 33 is mounted in the first blind hole 311, and then the first bolt 32 is slidingly inserted in the first blind hole 311 and abuts against the first elastic member 33;

[0080] The cover plate 1 is inclined to form an included angle with the horizontal plane, and then the second locking portion 34 is embedded and clamped in the second locking groove 22;

[0081] Turning the cover plate 1 around the joint of the second locking part 34 and the second locking groove 22, the first pin 32 is pressed to compress the first elastic member 33 and hide in the first blind hole 311; after the end of the first pin 32 away from the first elastic member 33 abuts against the inner wall of the shell 2, the pressing force applied on the first pin 32 is removed; then the cover plate 1 is turned to the position where the first pin 32 is aligned with the first pin hole 21; at this time, the first pin 32 is extended out of the first blind hole 311 under the elastic restoring force of the first elastic member 33 and is topped into the first pin hole 21, completing the anti-disassembly installation.

[0082] Compared with the prior art, the anti-disassembly mounting method of the embodiment is characterized in that: the first mounting block 31 and the second locking portion 34 are respectively arranged at the edges of two different sides of the end face of the cover plate 1 towards the shell 2, the first blind hole 311 of the first mounting block 31 is slidably inserted with the first bolt 32, and the first elastic member 33 is arranged between the first bolt 32 and the surrounding wall of the first blind hole 311; in the process of assembling the cover plate 1 at the opening of the shell 2, first, the cover plate 1 is inclined to form an angle with the horizontal plane, then the second locking portion 34 is inserted into the inside of the shell 2 and is clamped and connected in the second locking groove 22 (realizing the limiting connection of one side of the cover plate 1 and the corresponding side of the shell 2), and then the cover plate 1 is rotated around the connection between the second locking portion 34 and the second locking groove 22, when the first bolt 32 is about to contact the inner wall of the shell 2, the first bolt 32 is pressed to compress the first elastic member 33 into the first blind hole 311 (entering the locking state), so that the inner wall of the shell 2 abuts against the end of the first bolt 32 away from the first elastic member 33, and exerts a top force on the first bolt 32 to compress the first elastic member 33; when the cover plate 1 is rotated to the position where the first bolt 32 is aligned with the first pin hole 21, the top force exerted on the first bolt 32 to compress the first elastic member 33 disappears, so that the first bolt 32 is pushed into the first pin hole 21 under the elastic restoring force of the first elastic member 33 (entering the locking state), realizing the limiting connection of the two different sides of the cover plate 1 and the corresponding two sides of the shell 2, and external force cannot directly open the cover plate 1, the entire anti-disassembly mounting process does not need to rely on tools, and the mounting is convenient and efficient. By hiding the two anti-disassembly connection positions between the cover plate 1 and the shell 2 inside the shell 2 without exposure, the cover plate 1 and the shell 2 are mounted by the pure physical means with high reliability, and after the automobile controller product is assembled and completed at the factory, it is difficult for non-factory personnel to accurately know the two anti-disassembly connection positions of the cover plate 1 and the shell 2, thereby increasing the difficulty of violent disassembly for non-factory maintenance personnel, and the factory maintenance personnel can perform professional positioning and disassembly work according to the disassembly design position of the product; if the non-maintenance personnel forcibly choose to violently disassemble the cover plate 1 and the shell 2, the degree of physical partial damage to the connection between the cover plate 1 and the shell 2 is basically different from that when the factory maintenance personnel normally disassemble the cover plate 1 and the shell 2, thereby avoiding some subsequent guarantee disputes. At the same time, because the two anti-disassembly connection positions between the cover plate 1 and the shell 2 mounted by the anti-disassembly mounting method of the embodiment are hidden inside the shell 2 without exposure, whether it is violent disassembly of non-factory maintenance personnel or professional positioning and disassembly of factory maintenance personnel, a permanent disassembly mark record is left on the outer surface of the automobile controller, so that whether the automobile controller has been disassembled can be accurately identified from the appearance of the automobile controller.

[0083] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.
