Description

Technical Field

[0001] This utility model relates to the field of controller installation technology, and in particular to a controller support plate that prevents being stepped on. Background Technology

[0002] The electronic fuel injection controller (ECU) is the core component of the electronic fuel injection system (EFI / EGI). By receiving sensor signals and executing preset programs, it controls the fuel injection quantity, injection time, and injection pressure to ensure that the engine obtains the optimal air-fuel mixture concentration under various operating conditions.

[0003] Currently, a Chinese patent application with patent number "CN201921508146.1" discloses an installation device for a single-cylinder diesel engine fuel injection controller, including a limiting plate. The top of the limiting plate has a first groove, and the inner cavity of the first groove is movably connected to a controller body. The controller body has second grooves on both sides, and the inner cavity of the first groove has a third groove on both sides. The inner cavity of the third groove is movably connected to a first limiting block, and a movable block is fixedly connected to one side of the first limiting block. The side of the movable block away from the first limiting block extends into the inner cavity of the second groove. This utility model solves the problem of inconvenient installation of existing single-cylinder diesel engine fuel injection controllers by using a combination of a limiting plate, a first groove, a controller body, a second groove, a third groove, a first limiting block, a movable block, a pull rod, a first spring, a handle, a connecting block, a threaded hole, a limiting groove, a second limiting block, a sliding groove, a slider, a fourth groove, and a second spring. Although this device can improve the installation efficiency of the controller, since the existing controllers have improved service life and durability, they basically do not involve replacement. Therefore, the efficiency of installation does not play a significant role in the device's effectiveness. On the contrary, the protection of the controller after installation is neglected, so the damage to the controller is mostly caused by impacts from external objects, rather than reaching its service life.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered:

[0005] Poor protection and cumbersome installation of protective structures: In the daily operation and maintenance of automotive electronic control systems, electronic fuel injection controllers, as core components, often face the dual challenges of protection performance and ease of use. When vehicles are driving on complex road conditions, chassis components are easily impacted by flying stones or foreign objects. However, existing controllers generally lack effective external protective structures, causing impact energy to act directly on the device body.

[0006] Currently, most mainstream protection solutions use bolted metal protective covers. This structure requires the use of special tools to tighten the bolts one by one during installation, which takes about 15 minutes per installation. The bolts are also prone to loosening under vibration, requiring regular checks and tightening. The presence of the protective cover not only increases the installation and disassembly process by 30%, but its enclosed structure also causes the surface temperature of the controller to rise by 12-15°C during long-term operation, affecting heat dissipation efficiency. At the same time, it blocks the observation window, making it difficult for maintenance personnel to directly view the status indicator lights.

[0007] In actual maintenance scenarios, the terminal blocks on the top of the controller require frequent wiring adjustments and line replacements. When covered by the protective cover, the entire protective structure must be completely disassembled to access the wiring area. During an ECU upgrade, technicians repeatedly disassembled and reassembled the protective cover, causing the bolts to strip and become damaged. Ultimately, the entire protective component had to be replaced, adding an extra 40 minutes to the repair time. This design flaw significantly reduces work efficiency in the maintenance of electronic control systems that require high-frequency testing. At the same time, frequent disassembly may cause fatigue damage to the protective structure, which weakens its long-term protective performance. Therefore, we propose a controller support plate that is designed to prevent being stepped on. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides a controller support plate that prevents trampling, solving the technical problems of poor protection effect and cumbersome installation of the protective structure in existing fuel controllers during use.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A controller support plate for preventing trampling, the controller support plate comprising:

[0013] A base for supporting the controller;

[0014] Two symmetrically arranged baffles are connected to the upper and lower sides of the base respectively, and the baffles can be flipped toward the side of the base with the controller to wrap around the controller on the base.

[0015] Preferably, each side of the baffle is connected to a side arm, and the baffle is hinged to the base through the side arms;

[0016] The controller on the base is located between the two side arms, and the side arms do not contact the controller when the baffle flips in the direction of the controller.

[0017] Preferably, a side plate is connected to one side of the base, and the side plate is located on the path of the baffle flipping. When the baffle is parallel to the base, the baffle and the side plate are in contact with each other.

[0018] Preferably, one of the baffles has a U-shaped notch, and when the baffle and the base are perpendicular to each other, the notch on the baffle corresponds to the wiring of the controller.

[0019] Preferably, four rotating seats are installed at the front end of the base, and are respectively located on both sides of the base near the four corners. The rotating seats are inserted into the end of the side arm through the rotating shaft on their outer side, and the rotating shaft is used as the axis when the baffle is flipped.

[0020] The rotating seat has a protrusion on the side facing the rotating shaft, and the protrusion is located on the rotation path of the side arm. When the baffle is parallel to the base, the side arm is in contact with the protrusion.

[0021] Preferably, a connecting rod is connected between the two side arms on the same side, and the T-pin at the end of the connecting rod can slide along the slide groove on the side arm. A traction spring is embedded inside the slide groove, and the two ends of the traction spring are respectively connected to the inside of the slide groove and the T-pin.

[0022] When the T-pin is located at the end of the slide groove near the rotating seat, the traction spring is in a stretched state.

[0023] Preferably, when both baffles are parallel to the base, the distance between the two sliding grooves on the same side is equal to the distance between the two T-pins.

[0024] Preferably, the inner wall of the slide is provided with a locking structure, and the position of the T-pin is restricted by the locking structure.

[0025] Preferably, the locking structure includes a plurality of anti-reverse teeth evenly distributed on the edge of the slide groove, and the anti-reverse teeth are located on the side of the slide groove near the connecting rod. When the side arm is flipped away from the connecting rod, the T-pin engages with the anti-reverse teeth on the edge of the slide groove.

[0026] (III) Beneficial Effects

[0027] 1. Because a flip-up movable plate is used as the support plate side wall, its flipping function allows the baffle to be flipped to the top of the controller, thus covering the top of the controller. In the event of a "stepping" impact, it can provide support. At the same time, the edge of the baffle extends to the outside of the side plate, which can support the flipped baffle through the side plate, thereby improving the baffle's compressive strength. Therefore, it effectively solves the technical problems of poor protection effect and cumbersome installation of the protective structure in existing fuel controllers, thus achieving protection of the controller to avoid damage from being stepped on.

[0028] 2. Because a connecting rod connects the two baffles, and the T-pin on the connecting rod is inserted into the groove outside the side arm, the position of the two baffles can be restricted, forming a "rectangular frame" structure, thus protecting the controller and preventing damage to it. Secondly, because the T-pin and the groove are connected by a traction spring, after the baffles are installed, the connecting rod moves upward along the groove under the traction of the traction spring, thus automatically locking the baffles. Furthermore, the anti-reverse teeth on the edge of the groove can be used to insert the T-pin on the connecting rod into the anti-reverse teeth when the baffles are unfolded by external force, thereby locking the range of motion between the connecting rod and the side arm, thus locking the device and forming a stable "rectangular frame" structure.

[0045] This application provides an anti-trampling controller support plate, effectively solving the technical problems of poor protection and cumbersome installation of existing fuel controllers. It employs a flip-up movable plate as the side wall of the support plate. Utilizing its flipping function, the plate can be flipped to the top of the controller, thus covering the top of the controller. In the event of a trampling impact, it provides support. Simultaneously, the edge of the baffle extends to the outside of the side plate, allowing the side plate to support the flipped baffle, thereby improving its compressive strength and protecting the controller from trampling damage. A connecting rod connects the two baffles. Furthermore, the T-pin on the connecting rod is inserted into the slide groove on the outside of the side arm, which can limit the position of the two baffles and form a "rectangular frame" structure, thereby protecting the controller and preventing damage to it. Secondly, since the T-pin and the slide groove are connected by a traction spring, after the baffle is installed, the connecting rod moves upward along the slide groove under the traction of the traction spring, thereby automatically locking the baffle. Then, using the anti-reverse teeth on the edge of the slide groove, when the baffle is unfolded by external force, the T-pin on the connecting rod can be inserted into the anti-reverse teeth, thereby locking the range of motion between the connecting rod and the side arm, thus locking the device and forming a stable "rectangular frame" structure.

[0046] Example: The technical solution in this application is to address the issue that while existing fuel controller auxiliary devices can improve the installation efficiency of the controller, the lifespan and durability of existing controllers have been improved, so replacement is rarely required. Therefore, the efficiency of installation does not significantly improve the auxiliary effect of the device. Conversely, the protection of the controller after installation is neglected, resulting in most controller damage being caused by impacts from external objects rather than technical issues related to reaching the end of its lifespan. The overall approach is as follows:

[0047] In view of the problems existing in the prior art, the utility model provides an anti-trampling controller support plate, which is used to carry an electronic fuel injection controller and provide necessary protection for the controller at the same time. The controller support plate is mainly divided into three parts. First, it is the base 1 connected to the controller, and the controller is fixed on it by bolts. Second, it is the movable plate 3 that can be freely flipped. The movable plate 3 moves to the top of the controller in a flipped manner and covers the controller to protect the top of the controller. At the same time, it forms a "rectangular frame" - shaped protection frame with the connecting rod 54 to provide stable protection for the controller. The last one is the locking structure, which locks the position of the retaining piece 31 through the locking structure to maintain the stability of the "rectangular frame" form. The specific structure is as follows:

[0048] The base 1 is based on a rectangular plate - like structure. In order to improve the heat dissipation capacity of the controller and reduce the influence of the support frame on the controller, four cylindrical positioning rubber pads 4 are installed on the base 1. As Figure 1 shown, when the controller is installed, it is fixed on the positioning rubber pads 4 on the base 1 by bolts. Since the positioning rubber pads 4 protrude from the top of the base 1, after the controller is installed, there is a certain gap between the controller and the base 1, which is not only convenient for air flow (forming a heat dissipation loop); at the same time, it can also reduce the impact of the base 1 on the controller when it is hit.

[0049] In addition, a side plate 2 with an outward - turned edge is installed on one side of the base 1, and parts such as relays and fuses can be fixed on the side plate 2 to improve its bearing capacity.

[0050] The movable plate 3 is mainly composed of a rectangular retaining piece 31 and side arms 32 installed on both sides of the retaining piece 31. As Figure 2 and Figure 4 shown, the movable retaining piece 31 forms a "C" - shaped structure. Since the side arms 32 are hinged to the rotating seats 51 on the base 1, the shape of the retaining piece 31 can be kept stable. And in order to protect the top of the controller, using the flipping function of the side arms 32, the retaining piece 31 is flipped to the top of the controller to cover the controller and provide protection for the controller. As Figure 9 shown, in order to be able to drive the retaining piece 31 to flip, a torsion spring or a traction spring 53 and other structures that can provide a flipping force for the side arms 32 can be used to make the retaining piece 31 stably cover the top of the controller.

[0051] To prevent the side arms 32 from colliding with or rubbing against the controller during the flipping process, the distance between the two side arms 32 is enlarged so that the distance between them is greater than the width of the controller. In this way, the controller on the base 1 can be located between the two side arms 32. Based on this, when the baffle 31 flips towards the direction where the controller is located, the side arms 32 will not contact the controller, thereby improving the overall safety and stability.

[0052] During use, relying solely on the supporting force of the baffle 31 itself is not sufficient to cope with the impacts of various objects. Therefore, we have studied two schemes for auxiliary support. One is to utilize the side plate 2 on the base 1. By extending the side of the baffle 31 facing the side plate 2 outward so that it exceeds the edge of the side plate 2, as Figure 3 shown. In this way, the side plate 2 will be located on the flipping path of the baffle 31. By adjusting the length of the side arm 32, when the baffle 31 is parallel to the base 1, the baffle 31 and the side plate 2 are in mutual contact, that is, as Figure 3 shown in the lower part. At this time, the baffle 31 cannot continue to rotate, thereby restricting the rotation position of the baffle 31. In addition, when the baffle 31 is squeezed, the impact force can be transmitted to the side plate 2, and the side plate 2 provides a certain supporting force for it.

[0053] The second is to utilize the rotating seat 51 where the side arm 32 is hinged to the base 1 (the rotating seat 51 is inserted into the end of the side arm 32 through the rotating shaft 52 on its outer side). When the baffle 31 flips, it needs to take the rotating shaft 52 as the axis. In order to limit the flipping position of the baffle 31, a protrusion is provided on the side of the rotating seat 51 facing the rotating shaft 52, as Figure 2 and Figure 3 shown in the enlarged views. Make the protrusion located on the rotating path of the side arm 32. In this way, when the baffle 31 is parallel to the base 1, that is, as Figure 3 shown in the lower part, the side arm 32 contacts the protrusion. At this time, the baffle 31 cannot continue to rotate, thereby restricting the rotation position of the baffle 31. Among them, the rotating shaft 52 is inserted into the docking groove 34 on the side arm 32 correspondingly.

[0054] It is found during use that although the flipping function of the baffle 31 can play a protective role, the connected wires are located on the flipping path of the baffle 31 during the flipping process of the baffle 31. Therefore, to solve this problem, two methods are adopted. Method 1: After the baffle 31 is fixed, that is, as Figure 9 shown, there is a certain gap between the flipped baffle 31 and the base 1 after flipping, and wires can be installed using the gap. This method needs to be implemented after the device is installed and has certain limitations. Another method is to design the baffle 31 in this orientation into a "C" shape, that is, a notch is opened at the bottom of the baffle 31 and the notch corresponds to the connection end of the controller wire. In this way, when the baffle 31 and the base 1 are perpendicular to each other, as Figure 9As shown in the structural diagram on the right, the notch on the baffle 31 corresponds to the wiring point of the controller. This allows for continued adjustment before and after wiring, reducing installation difficulty. Similarly, the baffle 31 on the other side can be adjusted to allow the pipe to connect outward from that end.

[0055] To prevent the baffle 31 from flipping backward upon impact, a connecting rod 54 is connected between the two side arms 32 on the same side. The T-pin 55 at the end of the connecting rod 54 is inserted into the groove 33 on the outer side of the side arm 32 and can slide along the groove 33. This way, after the two baffles 31 have flipped into position, the connecting rod 54 is connected to restrict the position between the two baffles 31, preventing them from opening outward. A traction spring 53 is used as the power source. Both ends of the traction spring 53 are connected to the inside of the groove 33 and the T-pin 55, respectively. The tension of the traction spring 53 pulls the connecting rod 54 to a position near the baffle 31 on the side arm 32, thus preventing the side arm 32 from flipping backward. When the T-pin 55 is located at the end of the groove 33 near the rotating seat 51, the traction spring 53 is in a stretched state. This allows the connecting rod 54 to be pulled upward along the groove 33 after the side arm 32 has moved into position. Figure 7 As shown in (b) to (c), this achieves the purpose of automatic limiting (that is, it is only necessary to flip the baffle 31 so that it is flipped into place, and then the connecting rod 54 can lock the position of the baffle 31), and embed it into the slide groove 33 for concealment.

[0056] To achieve the automatic locking function, when both baffles 31 are parallel to the base 1 (i.e., when the baffles 31 move to the top of the controller), the distance between the two sliding grooves 33 on the same side and the distance between the two rotating shafts 52 on the same side must be equal to the distance between the two T-pins 55. Therefore, when the side arm 32 rotates, the T-pins 55 can move to a position coaxial with the rotating shafts 52, so the rotation of the side arm 32 will not affect the T-pins 55 and the connecting rods 54 connected to the T-pins 55; and when... Figure 7 In the state shown in (b), the elastic force of the traction spring 53 is perpendicular to the length direction of the connecting rod 54, and the connecting rod 54 can move under the action of the traction spring 53.

[0057] The locking structure, used to restrict the position of the T-pin 55, mainly includes several anti-reverse teeth 35 evenly distributed on the edge of the slide groove 33. The shape of the anti-reverse teeth 35 corresponds to the shape of the T-pin 55, such as... Figure 2 and Figure 3 As shown, the anti-reverse tooth 35 is located on the side of the slide groove 33 near the connecting rod 54. When the side arm 32 flips away from the connecting rod 54, the T-pin 55 and the anti-reverse tooth 35 on the edge of the slide groove 33 mesh with each other, so that the connecting rod 54 cannot move, thereby achieving the purpose of locking the baffle 31.

[0058] In the specific implementation process, the base 1 is first fixed. After the fixing is completed, the electronic fuel injection controller is placed on the base 1 and corresponds to the positioning pad 4 on the base 1. Since the positioning pad 4 protrudes from the base 1, a certain gap is reserved between the controller and the base 1 when the electronic fuel injection controller is installed on it, so as to facilitate air flow and remove the heat from the controller and improve the heat dissipation effect.

[0059] After the protective structure is activated and the controller is installed, the baffle 31 is in the following state: Figure 7 As shown in (a), both baffles 31 are then flipped toward the direction of the controller. Since the side arm 32 rotates around the rotating shaft 52 on the rotating seat 51, and the sliding groove 33 on the side arm 32 extends to the position of the rotating shaft 52 (i.e., the sliding groove 33 and the rotating shaft 52 are located on both sides of the side arm 32 and correspond to each other, as shown in (a), the side arm 32 rotates around the rotating seat 51. Figure 7 (Enlarged view) Furthermore, the distance between the two sliding grooves 33 on the same side and the distance between the two rotating shafts 52 on the same side are equal to the distance between the two T-pins 55. Therefore, when the side arm 32 rotates, the T-pins 55 can move to a position coaxial with the rotating shafts 52 (their central axes coincide). At this time, the rotation of the side arm 32 will not affect the T-pins 55 and the connecting rods 54 connected to the T-pins 55.

[0060] When the baffle 31 flips to be parallel to the base 1, as Figure 7 In the state shown in (b), the baffle 31 is in contact with the side plate 2 of the base 1, and the edge of the side arm 32 is in contact with the protrusion on the outside of the rotating seat 51. This restricts the baffle 31 from rotating while providing support for it, making it easier to provide additional support when it is squeezed or impacted. At this time, the baffle 31 cannot continue to rotate in the direction of the controller. Secondly, in this state, the side arm 32 is perpendicular to the base 1, and the extension direction of the slide groove 33 is perpendicular to the connecting rod 54. Since the T-pin 55 on the connecting rod 54 is connected to the end of the slide groove 33 by the traction spring 53 (the length of the traction spring 53 is less than the length of the slide groove 33, so when the T-pin 55 is located at the end of the slide groove 33 near the rotating seat 51, the traction spring 53 is in a stretched state), and the traction spring 53 is in a stretched state, the connecting rod 54 will move to the other end of the slide groove 33 (towards the baffle 31) under the traction of the traction spring 53 until the traction spring 53 is in a naturally stretched state. Figure 7 As shown in (c), the connecting rod 54 is connected between the side arms 32, locking the movement position of the side arms 32, thereby forming a "rectangular frame" structure. The stability of this structure is used to protect the controller.

[0061] In order not to affect the wiring of the controller, a notch is made in one of the baffles 31 so that the wires can pass through the notch and avoid the baffle 31 squeezing the wires. Of course, if the space is not enough, the other baffle 31 can also be designed with a notch of the same shape so as to accommodate more wires to pass through.

[0062] When opening the protective structure, first press the connecting rod 54 towards the base 1, so that the connecting rod 54 moves to the bottom position of the side arm 32, as shown. Figure 7 As shown in (b), at this time, the T-pin 55 moves to a position coaxial with the rotating shaft 52 (their central axes coincide). Then, the baffle 31 is flipped outward until the side arm 32 and the connecting rod 54 are on the same straight line. At this time, the elastic force of the traction spring 53 is in the same direction as the length of the connecting rod 54. Therefore, the elastic force of the traction spring 53 will not provide the baffle 31 with a force in the direction of flipping, and the position of the baffle 31 remains stable.

[0063] Secondly, because the edge of the slide groove 33 is provided with several anti-reverse teeth 35, and the shape of the anti-reverse teeth 35 corresponds to the shape of the T-pin 55, such as... Figure 2 and Figure 3 As shown, the anti-reverse tooth 35 is located on the side of the slide groove 33 near the connecting rod 54. Therefore, when the side arm 32 flips away from the connecting rod 54, the T-pin 55 and the anti-reverse tooth 35 on the edge of the slide groove 33 mesh with each other, making the connecting rod 54 unable to move, thereby achieving the purpose of locking the baffle 31.

[0064] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
