Description

Technical Field

[0001] This utility model relates to the field of vehicle electronics, and more specifically, to a vehicle-mounted manual / automatic electric power steering yaw generator. Background Technology

[0002] With the rapid development of the automotive industry, more and more cars are equipped with large central control screens. However, most of the in-vehicle central control screens on the market are currently fixed in angle or electrically tilted, and cannot be manually adjusted according to the individual needs of the driver and passenger, resulting in poor flexibility and convenience. In addition, the tilting mechanism of current in-vehicle screens mainly uses gears for transmission. That is, a gear is set on the shaft connected to the screen, and a matching gear is set on the output end of the motor. The tilting of the screen is driven by the meshing of the gears. However, there is usually play in the gear meshing (i.e., the ineffective travel caused by the tooth surface gap when the gears mesh). When the motor rotates forward and reverse, the gear teeth are prone to collision due to the play, which produces abnormal noise and affects the user experience. Utility Model Content

[0003] In view of this, the present invention provides an electric power steering yaw generator for vehicle-mounted manual / automatic transmission to solve the problems existing in the background art.

[0004] This utility model is achieved through the following technical solution.

[0005] A vehicle-mounted electric power steering yaw generator with manual / automatic transmission includes: a shaft assembly comprising a torsion bar, an input shaft, and an output shaft sequentially sleeved from the inside out, with both ends of the torsion bar fixedly connected to the input shaft and the output shaft, respectively; a transmission assembly comprising a backlash-free gear set and a transmission gear, the backlash-free gear set comprising an elastic connector, a first gear, and a second gear, the first gear and the second gear being sleeved on the outside of the output shaft, a first fixed post mounted on the first gear, and a second fixed post mounted on the second gear, with both ends of the elastic connector connected to the first fixed post and the second fixed post, respectively, so that the teeth of the first gear and the second gear abut against the two sides of the teeth of the transmission gear; a torque sensor for sensing the torsional angle between the input shaft and the output shaft; and a drive motor for driving the transmission gear to rotate.

[0006] The input shaft is connected to the screen at one end, and is fixedly connected to a torsion bar. One end of the torsion bar extends into the output shaft and is also fixedly connected to it. When manual screen adjustment is required, the user pushes the screen, causing the input shaft to rotate and the torsion bar to rotate as well. Because the torsion bar is an elastic structure and one end is fixedly connected to the output shaft, it undergoes elastic deformation. Since the output shaft does not move immediately, a torsion angle is generated between the input and output shafts due to the deformation of the torsion bar. At this time, the torque sensor senses the torsion signal and controls the drive motor to start. The drive motor drives the output shaft to rotate through the transmission assembly, compensating for the torsion angle of the input shaft, thus enabling manual electric-assisted screen adjustment. This electric-assisted function greatly reduces the resistance when manually pushing the screen, improving the user experience. When automatic screen adjustment is required, the drive motor directly drives the output shaft to rotate through the transmission assembly. The output shaft then drives the input shaft to rotate through the torsion bar. The torque sensor has a built-in angle encoder, which provides real-time feedback of the rotation angle, ensuring that the drive stops once the screen has reached the correct position, thereby achieving automatic screen adjustment.

[0007] It should be noted that the first fixed post is fixedly connected to the first gear, and the second fixed post is fixedly connected to the second gear. The elastic connector applies force to the first and second fixed posts, causing the first and second gears to engage with the left and right sides of the teeth on the transmission gear, respectively. When the drive motor rotates forward, the transmission gear meshes with the first gear, driving the output shaft to rotate. When the drive motor rotates in reverse, the transmission gear meshes with the second gear, driving the output shaft to rotate. Because the elastic connector is always in a stretched state, the first and second gears can be tightly engaged with the sides of the teeth on the transmission gear, eliminating tooth surface meshing clearance and preventing play during forward and reverse rotation. This eliminates collision noise caused by play, achieving silent operation and improving the user experience.

[0008] In one example of this utility model, the torque sensor is provided with a first magnetic ring rotor and a second magnetic ring rotor, the first magnetic ring rotor being mounted on the input shaft and the second magnetic ring rotor being mounted on the output shaft.

[0009] In the above scheme, the first magnetic ring rotor and the second magnetic ring rotor are respectively mounted on the input shaft and the output shaft. When the screen is manually driven to move, the input shaft rotates and drives the torsion bar to rotate. At this time, the magnetic flux between the two magnetic ring rotors changes. The torque sensor can send a signal to the drive motor according to the change in magnetic flux, so that the drive motor starts and drives the output shaft to rotate to compensate for the angle difference between the two magnetic ring rotors, thereby realizing the electric assist function.

[0010] In one example of this utility model, the first gear and the second gear are stacked, and the first gear has a clearance groove for the second fixing post to pass through.

[0011] In the above scheme, in order to make the structure more compact and save space, the first gear and the second gear are stacked, with the second gear located below the first gear, and the clearance groove is used for the second fixing post connected to the second gear to pass through, so that the second fixing post can be connected to the elastic connector.

[0012] In one example of this utility model, the torsion bar is provided with two pin holes that respectively cooperate with the input shaft and the output shaft, and a fixing pin is installed in the pin holes.

[0013] In the above scheme, the fixing pin is arranged radially along the torsion bar, input shaft, and output shaft. It ensures a rigid connection between the torsion bar and the input and output shafts, preventing relative rotation between them. This allows the elastic deformation of the torsion bar to be accurately converted into an angular difference between the input and output shafts, ensuring the realization of the electric assist function. Simultaneously, it also ensures that the output shaft can drive the input shaft to rotate via the torsion bar, achieving an automatic adjustment function.

[0014] In one example of this utility model, a damping sleeve is fitted onto the outer side of the output shaft, and multiple retaining rings are fitted onto the outer side of the damping sleeve.

[0015] In the above scheme, the damping sleeve is fitted on the outside of the output shaft, and the snap ring is used to clamp the damping sleeve onto the output shaft to ensure that the damping sleeve is in close contact with the surface of the output shaft. When the output shaft rotates, the damping sleeve and the surface of the output shaft generate damping force through contact friction, ensuring smooth operation. The magnitude of the generated damping force can be controlled by adjusting the number of snap rings, which is more convenient.

[0016] In one example of this invention, an adapter plate is connected to the end of the input shaft.

[0017] In the above scheme, the adapter board is used to mount the screen. When the screen is manually driven to move, the adapter board moves along with the screen to drive the input shaft to rotate.

[0018] In one example of this utility model, the transmission assembly further includes a worm gear, which is coaxially arranged with the transmission gear and fixedly connected to it. The output end of the drive motor is connected to a worm, which meshes with the worm gear.

[0019] In the above scheme, the rotation of the worm gear drives the transmission gear to rotate as well. The drive motor drives the worm gear to rotate through the worm at its output end. By setting up the worm gear and worm, the drive motor can be horizontally positioned to achieve transmission in a smaller space. Compared to directly driving the transmission gear through the drive motor, this significantly reduces the space occupied, improves space utilization, and makes the overall structure more compact. At the same time, the worm gear transmission has a self-locking function, which effectively protects the internal structure of the drive motor when subjected to external impacts, resulting in higher reliability.

[0020] In one example of this utility model, a top cover and a base are also included, with a receiving cavity formed between the top cover and the base.

[0021] In the above design, the top cover and the base are fitted together to form an internal cavity, providing space for each component.

[0022] In one example of this utility model, a backlash elimination assembly is installed on the input shaft. The backlash elimination assembly includes a bearing, an elastic spring, and two friction plates. The elastic spring is disposed between the two friction plates. The inner side of the upper cover is provided with a mounting groove that mates with the bearing. The two end faces of the bearing abut against the inner wall of the mounting groove and the friction plates, respectively.

[0023] In the above scheme, the input shaft is provided with a stepped part, the backlash elimination component is located between the stepped part and the inner wall of the upper cover, and an elastic spring is provided between the two friction plates. Under the action of the bearing and the stepped part on the input shaft, the elastic spring is pressed by the friction plates at both ends. Through the elastic force of the elastic spring, the axial wobble gap between the input shaft and the output shaft is eliminated, the vibration and impact are suppressed, and the transmission accuracy and structural stability are ensured at the same time.

[0024] In one example of this utility model, the backlash elimination assembly further includes an annular ring, which is sleeved on the outside of the input shaft and located between the bearing and the outer wall of the input shaft.

[0025] In the above scheme, the annular ring is placed between the mating surfaces of the bearing and the input shaft. Under the limiting action of the mounting groove, the bearing presses the annular ring onto the input shaft, thereby eliminating the radial wobble clearance of the input shaft.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: This application, by setting up a rotating shaft assembly and a torque sensor, utilizes the elastic deformation of the torsion bar and the sensing function of the torque sensor to enable the drive motor to assist when the user manually pushes the screen, reducing the resistance of manually pushing the screen, improving the user experience and flexibility. In addition, the screen can also automatically deflect under the drive of the drive motor, realizing manual and automatic integration, further improving the flexibility of use and meeting various user needs. This application includes a backlash elimination component, which comprises an elastic connector, a first gear, and a second gear. Through the elastic connector, the first gear and the second gear are respectively engaged with the left and right sides of the teeth on the transmission gear, eliminating the meshing backlash. When the drive motor rotates forward and backward, there is no play between the backlash elimination gear set and the transmission gear, which can avoid the generation of collision noise, achieve quiet operation, improve the user experience, suppress vibration and impact caused by collision, make the operation more stable, and protect the overall structure.

Detailed Implementation

[0038] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0039] Please refer to Figures 1 to 9 A vehicle-mounted electric power steering yaw generator with manual and automatic transmission includes a shaft assembly 1, a transmission assembly 2, a torque sensor 3, and a drive motor 4. The rotating shaft assembly 1 includes a torsion bar 11, an input shaft 12, and an output shaft 13, which are sequentially sleeved from the inside to the outside. The two ends of the torsion bar 11 are fixedly connected to the input shaft 12 and the output shaft 13, respectively. The transmission assembly 2 includes a backlash-free gear set 21 and a transmission gear 22. The backlash-free gear set 21 includes an elastic connector 213, a first gear 211, and a second gear 212. The first gear 211 and the second gear 212 are sleeved on the outside of the output shaft 13. A first fixed post 2111 is mounted on the first gear 211, and a second fixed post 2121 is mounted on the second gear 212. The two ends of the elastic connector 213 are connected to the first fixed post 2111 and the second fixed post 2121, respectively, so that the teeth of the first gear 211 and the second gear 212 abut against the two sides of the teeth of the transmission gear 22, respectively. The torque sensor 3 is used to sense the torsional angle between the input shaft 12 and the output shaft 13. The drive motor 4 is used to drive the transmission gear 22 to rotate.

[0040] Specifically, the top end of the input shaft 12 is used to connect to the screen. The input shaft 12 is fixedly connected to the torsion bar 11. The bottom end of the torsion bar 11 extends into the output shaft 13 and is fixedly connected to the output shaft 13. The input shaft 12 and the output shaft 13 can rotate relative to each other. When the screen needs to be manually adjusted, the user pushes the screen, and the input shaft 12 rotates with the screen, causing the torsion bar 11 to rotate as well. Since the torsion bar 11 is an elastic structure, it undergoes elastic deformation under the action of the input shaft 12. The output shaft 13 is fixedly connected to the bottom end of the torsion bar 11 and does not move temporarily. At this time, the input shaft 12 and the output shaft 13 generate a torsion angle due to the deformation of the torsion bar 11. At this time, the torque sensor 3 senses the torsion signal and controls the drive motor 4 to start. The drive motor 4 drives the output shaft 13 to rotate through the transmission component 2, compensating for the torsion angle of the input shaft 12, thereby realizing the function of manual electric assist adjustment of the screen. The electric assist function can greatly reduce the resistance when manually pushing the screen and improve the user experience. When automatic screen adjustment is required, the drive motor 4 directly drives the output shaft 13 to rotate through the transmission component 2. The output shaft 13 drives the input shaft 12 to rotate through the torsion bar 11. The torque sensor 3 has a built-in angle encoder, which provides real-time feedback on the screen's rotation angle, ensuring that the drive stops after the screen has rotated to the correct position, thereby realizing the automatic screen adjustment function.

[0041] The first fixed post 2111 is fixedly connected to the first gear 211, and the second fixed post 2121 is fixedly connected to the second gear 212. The elastic connector 213 applies force to the first fixed post 2111 and the second fixed post 2121, causing the first gear 211 and the second gear 212 to engage with the left and right sides of the teeth on the transmission gear 22, respectively. When the drive motor 4 rotates forward, the transmission gear 22 meshes with the first gear 211, driving the output shaft 13 to rotate. When the drive motor 4 rotates in reverse, the transmission gear 22 meshes with the second gear 212, driving the output shaft 13 to rotate. Because the elastic connector 213 is always in a stretched state, the first gear 211 and the second gear 212 can be tightly engaged with the sides of the teeth on the transmission gear 22, eliminating tooth surface meshing gaps and preventing play during forward and reverse rotation. This eliminates collision noise caused by play, achieving silent operation and improving the user experience.

[0042] It should be noted that the torsion bar 11 is an elastic structure used to transmit torque and generate identifiable deformation. The deformation of the torsion bar 11 directly corresponds to the magnitude of the manual pushing force. Since the torque sensor 3 cannot directly identify the magnitude of the pushing force, it can only detect the torsion angle signal after the torsion bar 11 deforms. When the user manually pushes the screen, the pushing force is transmitted to the torsion bar 11 through the input shaft 12. The elastic characteristics of the torsion bar 11 itself cause it to undergo slight elastic deformation when subjected to force, which neither interrupts the transmission of force nor creates a torsion angle difference between the input shaft 12 and the output shaft 13, thereby providing a signal source for the torque sensor 3 to ensure the reliability of the assist. Secondly, the torsion bar 11 has an elastic buffer function. If the torsion bar 11 is not set, the user's manual pushing force on the input shaft 12 and the electric assist on the output shaft 13 will form a rigid connection, which is prone to "assist lag" or "over-assist" phenomena. At this time, the screen deflection will either be stuttering or suddenly jerking, losing stability and smoothness, seriously affecting the user experience. In addition, the elastic deformation of the torsion bar 11 can play a certain buffering role, avoiding rigid impact between manual operation and drive motor 4 assistance, making the screen deflection process smoother and without jerking.

[0043] Preferably, the torsion bar 11 has pin holes 111 at its top and bottom ends, and the input shaft 12 and output shaft 13 have corresponding pin holes 111 that mate with the torsion bar 11. A fixing pin 14 is installed in the pin hole 111. The fixing pin 14 is arranged radially along the torsion bar 11, the input shaft 12, and the output shaft 13. It is used to ensure that a rigid connection is formed between the torsion bar 11 and the input shaft 12 and the output shaft 13, so that the elastic deformation of the torsion bar 11 can be accurately converted into the angular difference between the input shaft 12 and the output shaft 13, thereby ensuring the realization of the manual electric assist function. At the same time, it can also ensure that the output shaft 13 can drive the input shaft 12 to rotate through the torsion bar 11, thereby realizing the automatic adjustment function.

[0044] Preferably, the top ends of the torsion bar 11 and the input shaft 12 are also provided with matching pin holes 111, and a cylindrical pin is installed in the pin holes 111 to make the torsion bar 11 and the input shaft 12 securely connected.

[0045] Please refer to Figure 8 The torque sensor 3 is provided with a first magnetic ring rotor 31 and a second magnetic ring rotor 32. The first magnetic ring rotor 31 is mounted on the input shaft 12, and the second magnetic ring rotor 32 is mounted on the output shaft 13.

[0046] For example, when the user manually pushes the screen to deflect, the input shaft 12 rotates and drives the torsion bar 11 to rotate. At this time, the magnetic flux between the two magnetic ring rotors changes. The torque sensor 3 can send a signal according to the change in magnetic flux to start the drive motor 4, thereby driving the output shaft 13 to rotate to compensate for the angle difference between the two magnetic ring rotors, so that the screen rotates under manual drive and realizes the electric assist function.

[0047] If the force manually driving the screen disappears, the input shaft 12 stops rotating, the elastic deformation of the torsion bar 11 disappears, and the magnetic flux between the two magnetic ring rotors no longer changes. Therefore, the signal of the torque sensor 3 also no longer changes. At this time, the drive motor 4 stops assisting, and the screen stops moving under the action of damping force. This achieves the effect of the rotating shaft assembly 1 moving when manually driven and stopping when the manual drive is removed, thus realizing the screen's stop-and-go effect.

[0048] Preferably, to make the overall structure more compact, the torque sensor 3 is mounted on the outside of the input shaft 12 and does not rotate with the rotation of the input shaft 12.

[0049] Please refer to Figure 5 and Figure 6 To make the structure more compact and save space, the first gear 211 and the second gear 212 are stacked one on top of the other. The first gear 211 is located above the second gear 212. The first gear 211 has a clearance groove 2112 for the second fixing post 2121 connected to the second gear 212 to pass through, so that the second fixing post 2121 can be connected to the elastic connector 213.

[0050] Specifically, such as Figure 6 As shown, the teeth of the first gear 211 and the teeth of the second gear 212 are staggered vertically under the action of the elastic connector 213, so as to abut against the two sides of the teeth of the transmission gear 22 respectively. Figure 5 and Figure 6 From a top-down perspective, the teeth of the first gear 211 abut against the right side of the teeth of the transmission gear 22, and the teeth of the second gear 212 abut against the left side of the teeth of the transmission gear 22. When the transmission gear 22 rotates clockwise, it meshes with the first gear 211, which drives the output shaft 13 to rotate. When the transmission gear 22 rotates counterclockwise, it meshes with the second gear 212, which drives the output shaft 13 to rotate.

[0051] In some other embodiments (not specifically shown in the figures), the first gear 211 and the second gear 212 can be arranged vertically at intervals. In this case, the elastic connector 213 is located between the first gear 211 and the second gear 212, which can also achieve the same technical effect.

[0052] Preferably, the elastic connector 213 is a spring.

[0053] Please refer to Figure 9A damping sleeve 132 is fitted onto the outer side of the output shaft 13, and multiple retaining rings 133 are fitted onto the outer side of the damping sleeve 132. The damping sleeve 132 is fitted onto the outer side of the output shaft 13, and the retaining rings 133 are interference-fitted with the damping sleeve 132 (semi-open ring) to secure the damping sleeve 132 to the output shaft 13, ensuring tight contact between the damping sleeve 132 and the surface of the output shaft 13. When the output shaft 13 rotates, the damping sleeve 132 and the surface of the output shaft 13 generate damping force through contact friction, ensuring smooth operation. The magnitude of the generated damping force can be controlled by adjusting the number of retaining rings 133, providing greater convenience.

[0054] Please refer to Figure 1 and Figure 3 An adapter plate 5 is connected to the end of the input shaft 12. The adapter plate 5 is used to mount the screen. When the screen is manually driven to move, the adapter plate 5 moves with the screen and drives the input shaft 12 to rotate.

[0055] Please refer to Figure 2 and Figure 5 The transmission assembly 2 also includes a worm gear 23, which is coaxially arranged with the transmission gear 22 and fixedly connected to each other. The output end of the drive motor 4 is connected to a worm 41, which meshes with the worm gear 23.

[0056] When the worm gear 23 rotates, it drives the transmission gear 22 to rotate as well. The drive motor 4 drives the worm gear 23 to rotate through the worm 41 set at its output end. By setting the worm gear 23 and worm 41, the drive motor 4 can be set horizontally to achieve transmission in a smaller space. Compared with the method of directly driving the transmission gear 22 through the drive motor 4, it can greatly reduce the space occupied, improve space utilization, and make the overall structure more compact. At the same time, the worm gear 23 and worm 41 transmission has a self-locking function, which can effectively protect the internal structure of the drive motor 4 when subjected to external impact, thus improving reliability.

[0057] Please refer to Figures 1 to 4 The device also includes an upper cover 6 and a base 7, with a receiving cavity formed between the upper cover 6 and the base 7. After the upper cover 6 and the base 7 are fitted together, a receiving cavity is formed inside to provide space for each component.

[0058] The input shaft 12 is equipped with a backlash elimination assembly 15, which includes a bearing 151, an elastic spring 152 and two friction plates 153. The elastic spring 152 is located between the two friction plates 153. The top of the upper cover 6 is provided with a mounting groove 61 that mates with the bearing 151. The upper and lower end faces of the bearing 151 abut against the inner wall of the mounting groove 61 and the friction plates 153, respectively.

[0059] Specifically, the input shaft 12 is provided with a stepped portion 121, and the backlash elimination component 15 is located between the stepped portion 121 and the inner wall of the upper cover 6. An elastic spring 152 is provided between the two friction plates 153. The upper cover 6 pre-tightens the elastic spring 152 and the friction plates 153 through the bearing 151 and the stepped portion 121 on the input shaft 12. The elastic force of the elastic spring 152 eliminates the axial wobble gap between the input shaft 12 and the output shaft 13, suppresses vibration and impact, and ensures transmission accuracy and structural stability.

[0060] Preferably, the elastic spring 152 is a wave spring.

[0061] Furthermore, the backlash elimination assembly 15 also includes an annular ring 154, which is sleeved on the outside of the input shaft 12 and located between the mating surfaces of the bearing 151 and the input shaft 12. The bearing 151 is located in the mounting groove 61. Under the pre-tightening of the annular ring 154, the radial wobble gap of the input shaft 12 can be eliminated, making the overall structure more stable.

[0062] Preferably, the base 7 is also provided with a positioning pad 71, which is located on one side of the first gear 211 to provide cushioning and prevent collision.

[0063] Preferably, a controller 8 is installed on the top of the cover 6. The controller 8 can receive signals from the torque sensor 3 and control the operation of the drive motor 4, thereby realizing the control function of the entire device.
