Description

Technical Field

[0001] This utility model relates to the field of throttle motor technology, specifically a Hall effect throttle motor. Background Technology

[0002] Hall effect throttle motors are key actuators in modern vehicles, especially in electronically controlled engines and new energy vehicles. Their core function is to precisely control the engine's intake air volume, directly affecting the vehicle's power output, fuel economy, and emissions levels. With the increasing electronic and intelligent nature of automobiles, the requirements for the reliability, stability, and response accuracy of throttle motors are becoming increasingly stringent. A stable, secure mounting base is the physical prerequisite for ensuring precise control.

[0003] Currently, Hall effect throttle motors typically consist of a body and a mounting plate. The body is mounted on the mounting plate and is directly fixed to the corresponding position in the engine compartment or chassis using ordinary screws through the mounting plate and its mounting holes. This is the most basic mechanical connection method, and its anti-loosening ability relies almost entirely on the preload of the screws themselves and the friction between the threaded pairs.

[0004] However, screws are prone to plastic relaxation or microscopic slippage between threaded pairs under long-term vibration, which leads to a decrease in preload and loosening, posing a significant safety hazard.

[0005] Based on this, this utility model designs a Hall effect throttle motor to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A plurality of guide grooves are provided on the mounting plate, and the guide grooves are symmetrically arranged around the periphery of the screw. A slider is slidably disposed in the guide groove, and a clamping block is fixedly disposed on the slider. The clamping block is provided with external threads, and a connecting cover is detachably disposed on the clamping block. The connecting cover is provided with internal threads, and the external threads of the clamping block cooperate with the internal threads on the connecting cover. When the connecting cover is screwed down, the clamping block converges along the guide groove towards the center of the screw and presses against the outer surface of the screw nut.

[0007] By adopting the above technical solution, a clamping block with external threads and a connecting cover with internal threads are set up. The radial convergence movement of the clamping block is realized by the thread engagement mechanism. When the connecting cover is tightened downwards, multiple clamping blocks can be driven to move synchronously towards the center, thereby uniformly pressing the outer surface of the screw and nut from all sides. This structure effectively limits the radial wobble and axial loosening of the screw, and significantly improves the installation stability of the motor.

[0008] Preferably, the outer diameter of the clamping block increases from top to bottom.

[0009] By adopting the above technical solution, the outer periphery of the clamping block is designed with a diameter that increases from top to bottom to form a conical structure. The conical surface cooperates with the inner wall of the connecting cover, which can efficiently convert the downward rotating motion of the connecting cover into the horizontal centripetal motion of the clamping block, thereby improving the force transmission efficiency and the synchronization of the clamping action, and making the locking force distribution more uniform.

[0010] Preferably, a return spring is provided in the guide groove, and when the connecting cover is removed from the clamping block, the return spring pulls the clamping block to move away from the screw.

[0011] By adopting the above technical solution, a reset spring is set in the guide groove, which can automatically push the clamping block away from the center of the screw when the connecting cover is removed, so that it can quickly reset. This design facilitates the installation, adjustment and disassembly of the screw and improves the efficiency of equipment maintenance.

[0012] Preferably, four clamping blocks are provided, and the four clamping blocks are evenly distributed along the circumference of the screw.

[0013] By adopting the above technical solution, using four clamping blocks evenly distributed around the circumference, a balanced clamping force can be applied to the screw and nut from four directions, effectively avoiding screw misalignment or loosening caused by uneven force on one side, and further enhancing the reliability and stability of locking.

[0014] Preferably, a buffer pad is provided on the side of the clamping block near the screw.

[0015] By adopting the above technical solution, on the one hand, the anti-loosening effect can be enhanced by increasing friction, and on the other hand, vibration energy can be buffered and absorbed. At the same time, the hard clamping block is prevented from directly contacting and scratching the surface of the screw and nut, thus playing a protective role.

[0016] Preferably, the top of the connecting cover is provided with a screw groove.

[0017] By adopting the above technical solution, a screw-in groove is provided on the top of the connecting cover, facilitating screw-in operations using a standard screwdriver or special tools. This not only saves effort but also allows for more precise torque control, ensuring the connecting cover is tightened to the optimal position.

[0018] Preferably, the mounting plate is provided with reinforcing ribs on the outer periphery of the guide groove.

[0019] By adopting the above technical solutions, the structural rigidity and strength of the mounting plate body can be significantly enhanced, preventing the mounting plate from deforming or being damaged due to stress concentration under long-term vibration or repeated tightening operations, thereby extending the service life of the entire component.

[0020] In summary, this application has the following beneficial technical effects: by setting up a clamping block with external threads and a connecting cover with internal threads, the radial convergence movement of the clamping block is realized by using a thread engagement mechanism. When the connecting cover is tightened downwards, multiple clamping blocks can be driven to move synchronously towards the center, thereby uniformly pressing the outer surface of the screw and nut from all sides. This structure effectively limits the radial wobble and axial loosening of the screw, and significantly improves the installation stability of the motor. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] A Hall effect throttle motor includes a mounting plate 1, which serves as the mounting base for the motor body. The mounting plate 1 has a central through hole for a screw 6 to pass through, and four symmetrical guide grooves 7 arranged in a ring around the central through hole. The mounting plate 1 has several guide grooves 7 arranged symmetrically around the screw 6. A slider 12 is slidably disposed in the guide grooves 7. A clamping block 4 is fixedly disposed on the slider 12. Four clamping blocks 4 are evenly distributed around the screw 6. The clamping blocks 4 have external threads 10. A connecting cover 2 is detachably disposed on the clamping blocks 4. The connecting cover 2 has internal threads 11. The external threads 10 of the clamping blocks 4 engage with the internal threads 11 on the connecting cover 2.

[0027] In use, screw 6 is passed through the central through hole of mounting plate 1 and initially screwed into the target installation position. After screw 6 is tightened, connecting cover 2 is placed on the four clamping blocks 4 and the connecting cover 2 is rotated downward. As the connecting cover 2 is rotated downward, its internal conical guide surface contacts the conical outer surface of the four clamping blocks 4 and generates an interaction force. This force decomposes the downward rotation of the connecting cover 2 into two components on the clamping blocks 4: a downward pressure and a radial clamping force pointing towards the center of screw 6. Under this action, the four clamping blocks 4 overcome the elastic force of the return spring 8 and converge towards the center synchronously and smoothly along their respective guide grooves 7. The buffer pads 5 on their inner sides are then tightly pressed against the outer surface of the screw 6 nut. The strong clamping force eliminates the radial gap between screw 6 and mounting plate 1, making the connection between screw 6 and mounting plate 1 tighter, effectively reducing the shaking of screw 6 under vibration, and improving the installation stability of the motor.

[0028] The outer diameter of the clamping block 4 increases from top to bottom, which makes the force of the connecting cover 2 on the clamping block 4 more obvious when the connecting cover 2 rotates downward. After the clamping block 4 comes into contact with the nut on the screw 6, the connecting cover 2 continues to be screwed downward, which can make the clamping block 4 press more tightly against the nut, further improving the connection tightness between the screw 6 and the mounting plate 1.

[0029] A return spring 8 is provided in the guide groove 7. When the connecting cover 2 is removed from the clamping block 4, the return spring 8 pulls the clamping block 4 to move away from the screw 6. When disassembly is required, simply loosen the connecting cover 2 counterclockwise. As the connecting cover 2 moves upward, its radial constraint on the clamping block 4 is released. The elastic force of the return spring 8 will immediately push the four clamping blocks 4 apart, separating them from the screw 6 nut and restoring them to their initial state. At this time, the screw 6 can be unscrewed or adjusted without obstruction, which improves the disassembly speed of the screw 6.

[0030] A buffer pad 5 is provided on the side of the clamping block 4 near the screw 6. The buffer pad 5 is made of elastic and wear-resistant material. When the clamping block 4 is brought together, the soft buffer pad 5 will undergo slight deformation under pressure, thereby increasing the actual contact area with the screw 6 nut and generating strong static friction, ensuring that the clamping force is evenly applied to the entire contact surface of the nut. The top of the connecting cover 2 is provided with a screw-tightening groove 3. By using a torque wrench with the corresponding bit, the installer can accurately tighten the connecting cover 2 to the preset and optimal torque value, preventing problems such as permanent deformation of the buffer pad 5, damage to the slider 12 or guide groove 7 caused by over-tightening. The mounting plate 1 is provided with a reinforcing rib 9 on the outer periphery of the guide groove 7. The clamping block 4 is provided with a clearance groove for the reinforcing rib 9 to pass through, which can significantly enhance the structural rigidity and strength of the mounting plate 1 body and prevent the mounting plate 1 from deforming or being damaged due to stress concentration under long-term vibration or repeated tightening operations.

[0031] The implementation principle of this embodiment is as follows: When the operator uses a tool to screw on the connecting cover 2, the conical guide surface on the inner wall of the connecting cover 2 interacts with the conical surface on the outside of the clamping block 4. The downward screwing motion of the connecting cover 2 is efficiently converted and decomposed into a radial force that drives all the clamping blocks 4 to converge towards the center along the guide groove 7 through the inclined action of this pair of conical surfaces. As the clamping blocks 4 converge towards the center, the elastic buffer pad 5 on its inner side is tightly pressed against the side surface of the screw 6 nut, making the connection between the screw 6 and the mounting plate 1 tighter, effectively reducing the shaking of the screw 6 under vibration, and improving the installation stability of the motor. When disassembly is required, simply loosen the connecting cover 2 counterclockwise. As the connecting cover 2 moves upward, its radial constraint on the clamping block 4 is released, and the elastic force of the return spring 8 will immediately push the four clamping blocks 4 apart, separating them from the screw 6 nut and restoring them to the initial state. At this time, the screw 6 can be unscrewed or adjusted without hindrance.
