Description

Technical Field

[0001] This utility model relates to the field of steer-by-wire technology, and in particular to a multifunctional assembly fixture for a steer-by-wire system. Background Technology

[0002] Steer-by-wire (B-B) is an advanced vehicle steering technology that eliminates the traditional mechanical driveshaft, connecting the steering wheel and steering mechanism solely through electrical wires. This system relies entirely on electrical signals to transmit control commands, thus achieving indirect physical torque transmission between the driver and the steering mechanism. The execution layer of the B-B system is responsible for actually performing the steering actions.

[0003] In existing technologies, steer-by-wire consists of two actuators: a steering rack and a steering wheel. The steering rack requires the assembly of various parts, including bearings, sensors, and connectors, to ensure smooth sliding or rotation, thereby improving the response speed of the steering system. However, when assembling parts, since the shaft is long and each part of the shaft needs to be assembled, the shaft is usually fixed from both ends. When facing assembly pressure in different parts, the clamp position is not adjustable, which can easily lead to the lack of effective support in the middle part of the shaft, resulting in bending deformation. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multifunctional assembly fixture for a steer-by-wire system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional assembly fixture for a steer-by-wire system, comprising a clamping mechanism, a connecting mechanism at one end of the clamping mechanism, the clamping mechanism comprising a main frame, an L-plate on the inner wall of the main frame, the inner wall of the main frame being slidably connected to the outer side of one end of the L-plate, a collar at the other end of the L-plate being fixedly connected to one side of the collar, a hollow disc on the inner surface of the collar being rotatably connected to the outer side of the hollow disc, a pressing plate inside the hollow disc being fixedly connected to one end of the pressing plate, a clamping plate on the inclined surface of the pressing plate, and the inclined surface of the pressing plate rotatably contacting one end of the clamping plate.

[0006] In a preferred embodiment, the connecting mechanism includes a rice rod, one end of which is provided with a stop block and is fixedly connected to one end of the stop block. A sub-roller is provided on the outer side of the rice rod and is connected through the inner wall of the sub-roller. A secondary frame is provided on the outer side of the rice rod and is rotatably connected through the inner wall of the secondary frame.

[0007] In a preferred embodiment, a fixing ring is provided on the outer side of the clamping plate, and the outer side of the clamping plate is slidably connected to the inner wall of the fixing ring. A fixing plate is provided on the inner wall of the fixing ring, and one end of the fixing plate is fixedly connected to the inner wall of the fixing ring. The side of the fixing ring is fixedly connected to the inner surface of the collar.

[0008] In a preferred embodiment, a spring is provided on one side of the fixing plate, one side of the fixing plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the inner wall of the clamping plate.

[0009] In a preferred embodiment, one end of the fixed ring is fixedly connected to the interior of the empty disc, one end of the empty disc is provided with a mother roller, one end of the empty disc is fixedly connected to one end of the mother roller, a belt is provided on the outside of the mother roller, and the outside of the mother roller is connected to the inside of the belt for transmission.

[0010] In a preferred embodiment, the inner side of the belt is connected to the outer side of the sub-roller, a motor is provided at the center of one end of the sub-roller, the center of one end of the sub-roller is fixedly connected to the output end of the motor, and the outer side of the motor is fixedly connected to one end of the side of the sub-frame.

[0011] In a preferred embodiment, the top of the sub-frame is fixedly connected to one side of the L-plate, and a protruding rod is provided on the other side of the L-plate, with the other side of the L-plate being fixedly connected to one end of the protruding rod.

[0012] In a preferred embodiment, a telescopic rod is provided at one side end of the main frame, and the side end of the main frame is fixedly connected to the bottom end of the telescopic rod. A sliding plate is provided at the top end of the telescopic rod, and the top end of the telescopic rod is fixedly connected to the bottom end of the sliding plate. An inclined groove is provided on the inner wall of the sliding plate, and the inner surface of the inclined groove is slidably connected to the outer side of the protruding rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. By opening a sloping groove on the slide plate, the telescopic rod is retracted, causing the slide plate to move down from its original position. Its inner wall will generate a lateral thrust on the convex rod. Under the action of this thrust, the L-plate will slide along the inner wall of the main frame, and the distance between the two L-plates will increase, which can meet the assembly operation of shafts of different lengths. Start the motor to make the sub-roller rotate, and let the belt drive the empty disc on the mother roller to rotate in the collar. During the rotation, the extrusion plate will generate an external force on one end of the clamping plate, causing the two clamping plates to move in the same direction. And because the clamping surface of the clamping plate is V-shaped, this design can adapt to shafts of different diameters. 2. By designing the rice rod at one end of the sub-roller, since there are two sub-rollers, the rice rod is fixedly connected to the center of one sub-roller and passes through the center of the other sub-roller. At this time, because the rice rod passes through the center of the other sub-roller, the rotating rice rod will drive the sub-roller to rotate together, and the rotation direction and speed of the two sub-rollers are consistent. At the same time, even if the distance between the two sub-rollers is increased, an effective transmission connection can still be maintained in this way. Attached Figure Description

Example

[0023] like Figure 1 - Figure 7 As shown, this utility model provides a technical solution: a multi-functional assembly fixture for a steer-by-wire system, including a clamping mechanism 1. One end of the clamping mechanism 1 is provided with a connecting mechanism 2. The clamping mechanism 1 includes a main frame 11, with an L-plate 12 on its inner wall. The inner wall of the main frame 11 is slidably connected to the outer side of one end of the L-plate 12. A collar 13 is provided at the other end of the L-plate 12, and the other end of the L-plate 12 is fixedly connected to one side of the collar 13.

The interior of the hollow disc 14 is provided with... The extrusion plate 17 is fixedly connected to one end of the empty disc 14. A clamping plate 16 is provided on the inclined surface of the extrusion plate 17, and the inclined surface of the extrusion plate 17 rotatably contacts one end of the clamping plate 16. A fixing ring 15 is provided on the outer side of the clamping plate 16, and the outer side of the clamping plate 16 is slidably connected to the inner wall of the fixing ring 15. A fixing plate 19 is provided on the inner wall of the fixing ring 15, and the inner wall of the fixing ring 15 is fixedly connected to one end of the fixing plate 19. A spring 18 is provided on one side of the fixing plate 19, and one side of the fixing plate 19 is fixedly connected to one end of the spring 18. The other end of the spring 18 is connected to the clamping plate 16. The inner wall is fixedly connected, and one end of the fixing ring 15 is fixedly connected to the inside of the empty disk 14. A mother roller 118 is provided at one end of the empty disk 14, and one end of the empty disk 14 is fixedly connected to one end of the mother roller 118. A belt 117 is provided on the outside of the mother roller 118, and the outside of the mother roller 118 is connected to the inside of the belt 117. The inside of the belt 117 is connected to the outside of the child roller 116. A motor 115 is provided at the center of one end of the child roller 116, and the center of one end of the child roller 116 is fixedly connected to the output end of the motor 115. The outside of the motor 115 is fixedly connected to one end of the side of the auxiliary frame 114. Next, the top of the sub-frame 114 is fixedly connected to one side of the L-plate 12. The other side of the L-plate 12 is provided with a protruding rod 112, and the other side of the L-plate 12 is fixedly connected to one end of the protruding rod 112. One side of the main frame 11 is provided with a telescopic rod 113, and one side of the main frame 11 is fixedly connected to one side of the bottom of the telescopic rod 113. The top of the telescopic rod 113 is provided with a sliding plate 110, and the top of the telescopic rod 113 is fixedly connected to the bottom of the sliding plate 110. The inner wall of the sliding plate 110 is provided with a sloping groove 111, and the inner surface of the sloping groove 111 is slidably connected to the outer side of the protruding rod 112.

[0024] In this embodiment, the multi-functional assembly fixture for the steer-by-wire system utilizes a designed main frame 11. The inner wall of the main frame 11 has two L-plates 12 that can slide along the inner wall of the main frame 11. Each L-plate 12 has a collar 13 connected to one end, and the components covered within the two collars 13 are identical. A hollow disc 14 is designed on the inner surface of the collar 13, allowing rotation. Inside the hollow disc 14, two equidistant pressing plates 17 are designed, each with an inclined surface. A fixing ring 15 is designed at the center of the hollow disc 14, with two clamping plates 16 penetrating its inner wall. The clamping plates 16... The clamping surface is V-shaped, and one end of the clamping plate 16 contacts the inclined surface of the extrusion plate 17. Then, by fixing a mother roller 118 to one end of the empty disc 14, and a belt 117 is sleeved on the mother roller 118, and the other end of the belt 117 is sleeved on the outside of the child roller 116, the motor 115 is started to make the child roller 116 rotate, and the belt 117 drives the empty disc 14 on the mother roller 118 to rotate at a small angle within the collar 13. During the rotation, the extrusion plate 17 will generate an external force on one end of the clamping plate 16, so that the two clamping plates 16 move in the same direction. Thus, the shaft can be effectively clamped when assembling the steering system. And because the clamping surface of the clamping plate 16 is V-shaped, this design can adapt to shafts of different diameters. A protruding rod 112 is designed on one side of the L-plate 12. The outer side of the protruding rod 112 is located on the inner surface of the inclined groove 111. The inclined groove 111 is opened on the inner wall of the slide plate 110. The slide plate 110 can move up and down a short distance on one side of the main frame 11. Then, by retracting the telescopic rod 113, the slide plate 110 moves down on the original basis. Its inner wall will generate a lateral thrust on the protruding rod 112. Since the protruding rod 112 is fixed on the side of one end of the L-plate 12, under the action of this thrust, the L-plate 12 will slide along the inner wall of the main frame 11. The distance between the two L-plates 12 will increase, so that the two collars 13 and their internal clamping components can adjust the spacing according to the assembly requirements of the steering system to meet the assembly operation of shafts of different lengths. A spring 18 is designed on the inner wall of the clamping plate 16. One end of the spring 18 is fixed to the fixing plate 19, and one end of the fixing plate 19 is fixed to the inner wall of the fixing ring 15. When the clamping plate 16 is no longer subjected to the external force of the pressing plate 17, the spring 18 will use its own elastic release ability to reset the clamping plate 16, thereby quickly releasing the fixation of the shaft. Example

[0025] like Figure 1 - Figure 7As shown, the connecting mechanism 2 includes a rice rod 21, a stop block 22 is provided at one end of the rice rod 21, and one end of the rice rod 21 is fixedly connected to one end of the stop block 22. A sub-roller 116 is provided on the outer side of the rice rod 21, and the outer side of the rice rod 21 is connected through to the inner wall of the sub-roller 116. A secondary frame 114 is provided on the outer side of the rice rod 21, and the outer side of the rice rod 21 is rotatably connected through to the inner wall of the secondary frame 114.

[0026] In this embodiment, the rice rod 21 is designed to be at one end of the sub-roller 116. Since there are two sub-rollers 116, the rice rod 21 is fixedly connected to the center of one sub-roller 116 and penetrates through the center of the other sub-roller 116. This allows the rice rod 21 to rotate synchronously when the sub-roller 116 fixedly connected to the rice rod 21 rotates under the drive of the motor 115. At this time, because the rice rod 21 penetrates through the center of the other sub-roller 116, the rotating rice rod 21 will drive the sub-roller 116 to rotate together, and the rotation direction and speed of the two sub-rollers 116 are consistent. At the same time, even when the distance between the two sub-rollers 116 increases, an effective transmission connection can still be maintained in this way. A stop block 22 is installed at one end of the rice rod 21. The stop block 22 can axially limit the penetration of the sub-roller 116 and prevent the sub-roller 116 from detaching from the rice rod 21, ensuring that the rice rod 21 and the sub-roller 116 always maintain a penetration engagement state.

[0027] Working principle: like Figure 1 - Figure 7 As shown, a mother roller 118 is fixed to one end of the empty disc 14, and a belt 117 is sleeved on the mother roller 118. The other end of the belt 117 is sleeved on the outside of the child roller 116. This starts the motor 115, causing the child roller 116 to rotate. The belt 117 drives the empty disc 14 on the mother roller 118 to rotate at a small angle within the collar 13. During the rotation, the pressing plate 17 applies an external force to one end of the clamping plate 16, causing the two clamping plates 16 to move in the same direction. This effectively clamps the shaft components when assembling the steering system. Secondly, by retracting the telescopic rod 113, the slide plate 110 moves downward from its original position, and its inner wall generates a lateral thrust on the protruding rod 112. Since the protruding rod 112 is fixed to the side of one end of the L plate 12, under the action of this thrust, the L plate 12 slides along the inner wall of the main frame 11, increasing the distance between the two L plates 12. This allows the two collars 13 and their internal clamping components to adjust the spacing according to the assembly requirements of the steering system. The rice rod 21 is designed to be attached to one end of the sub-roller 116. Since there are two sub-rollers 116, the rice rod 21 is fixedly connected to the center of one sub-roller 116 and passes through the center of the other sub-roller 116. At this time, because the rice rod 21 passes through the center of the other sub-roller 116, the rotating rice rod 21 will drive the sub-roller 116 to rotate together, and the rotation direction and speed of the two sub-rollers 116 are consistent. At the same time, it can ensure that the transmission between the two sub-rollers 116 will not be interrupted after the distance between the two sub-rollers 116 is increased. The stop block 22 fixed to one end of the rice rod 21 can prevent the passing sub-roller 116 from detaching from the rice rod 21.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
