Description

Technical Field

[0001] This utility model relates to the field of structural design technology for driving school training vehicles, specifically to a clutch motor assembly structure. Background Technology

[0002] In the field of motor vehicle driver training, improving trainees' operational proficiency has always been a core issue for teaching safety. Current technology generally employs a purely manual operation mode for clutch control in the driver's seat, relying entirely on the trainee's subjective judgment and manual intervention. While this design meets basic teaching needs, it reveals significant limitations in independent training or examination scenarios.

[0003] When trainees are in independent training without an instructor, or when they are under pressure due to driving test anxiety, the safety performance of a purely manually controlled driver's clutch system is significantly reduced. On one hand, trainees, lacking experience, are prone to miscoordinating the clutch with the accelerator / brake. Without an instructor's intervention in the passenger seat, the vehicle may enter a dangerous situation due to improper operation (such as stalling and rolling backwards, or overheating caused by clutch slippage). On the other hand, the psychological pressure of the test scenario further amplifies the probability of trainees' operational errors. If manual intervention is relied upon at this time, the response is delayed, turning the device, originally intended to ensure safety, into a potential source of risk. Therefore, developing a driver's clutch system that combines the flexibility of manual control with the precision of intelligent response has become an urgent need to improve driving test safety. Utility Model Content

[0004] Based on the above description, this utility model provides a clutch motor assembly structure to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A clutch motor assembly structure for clutch control of a driving school training vehicle in the driver's seat includes a mounting bracket, a motor drive assembly, and a foot pedal drive assembly. The mounting bracket includes a first mounting plate, a second mounting plate, a sleeve, and a connector; the first mounting plate and the second mounting plate are arranged at intervals relative to each other, forming an inner space between them; a first mounting hole is formed on the first mounting plate; the sleeve is connected to the side of the second mounting plate opposite to the first mounting plate; a second mounting hole communicating with the sleeve is formed on the second mounting plate; and the connector is mounted on the sleeve for connection to the vehicle body. The motor drive assembly includes a motor, an active swing arm, and a contact member. The motor is connected to the outside of the first mounting plate. One end of the active swing arm is connected to the output shaft of the motor and is perpendicular to the output shaft of the motor. The active swing arm is located in the inner space. The contact member is connected to the end of the active swing arm away from the motor. The foot pedal drive assembly includes an inner shaft, a driven rod, a force transmission plate, and a clutch lever. The inner shaft is rotatably disposed inside a sleeve. The driven rod and the force transmission plate are respectively vertically connected to both ends of the inner shaft. The driven rod is disposed in the inner space and is correspondingly disposed with the abutment. One end of the clutch lever is connected to the force transmission plate, and the other end is used to connect to the clutch pedal. The driven rod is rotated by being pulled by the clutch lever or by being pushed by the abutment.

[0006] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: (1) The mounting bracket adopts a structure with the first mounting plate and the second mounting plate spaced apart. Combined with the combination design of the sleeve and the connector, it forms a compact and stable mechanical support frame. The inner space provides an installation area for the combination of the two driving modes, avoiding the interference of exposed parts to the driving space. The connecting structure between the sleeve and the second mounting hole is directly fixed to the vehicle body through the connector, which simplifies the assembly process and improves the compatibility of the device with different vehicle models.

[0007] (2) The two clutch control modes are linked by the contact transmission of the contacting part and the driven rod: In the intelligent mode, the motor can drive the active rocker arm to rotate through the output shaft, push the contacting part to contact the driven rod, and then drive the inner shaft to rotate and pull the clutch lever through the force transmission plate to realize the automatic stepping of the clutch pedal; in the manual mode, the clutch pedal can be stepped on directly by the manual.

[0008] In summary, this technical solution, through structural innovation and the integration of drive modes, has achieved systematic improvements in installation adaptability, operational compatibility, control precision, and safety assurance, providing key technical support for the upgrade of the master driving clutch device from manual assistance to intelligent collaboration.

[0012] Furthermore, it also includes an elastic assist component, one end of which is connected to the first mounting plate and the other end is connected to the active swing arm, for elastically driving the active swing arm to swing so that the abutment member moves away from the driven rod.

Detailed Implementation

[0019] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0021] like Figures 1 to 6 As shown, this application embodiment provides a clutch motor assembly structure for clutch control of a driving school training vehicle in the driver's seat, which includes a mounting bracket 10, a motor drive assembly 20 and a foot pedal drive assembly 30. Mounting bracket 10 includes a first mounting plate 11, a second mounting plate 12, a sleeve 13, and a connector 14; the first mounting plate 11 and the second mounting plate 12 are arranged at intervals relative to each other, and an inner space is formed between the first mounting plate 11 and the second mounting plate 12; a first mounting hole 11a is formed on the first mounting plate 11; the sleeve 13 is connected to the side of the second mounting plate 12 away from the first mounting plate 11; a second mounting hole 12a communicating with the sleeve 13 is formed on the second mounting plate 12; and the connector 14 is mounted on the sleeve 13 for connection with the vehicle body. The motor drive assembly 20 includes a motor 21, an active rocker arm 22, and a contact member 23. The motor 21 is connected to the outside of the first mounting plate 11. One end of the active rocker arm 22 is connected to the output shaft of the motor 21 and is set perpendicular to the output shaft of the motor 21. The active rocker arm 22 is located in the inner space. The contact member 23 is connected to the end of the active rocker arm 22 away from the motor 21. The foot pedal drive assembly 30 includes an inner shaft 31, a driven rod 32, a force transmission plate 33, and a clutch lever 34. The inner shaft 31 is rotatably disposed inside the sleeve 13. The driven rod 32 and the force transmission plate 33 are respectively vertically connected to the two ends of the inner shaft 31. The driven rod 32 is disposed in the inner space and is correspondingly disposed with the abutment member 23. One end of the clutch lever 34 is connected to the force transmission plate 33, and the other end is used to connect to the clutch pedal. The driven rod 32 is rotated by being pulled by the clutch lever 34 or by being pushed by the abutment member 23.

[0022] In this embodiment, the mounting bracket 10 serves as the mechanical support and spatial carrier of the entire device. It adopts an alternating layout of a first mounting plate 11 and a second mounting plate 12, which are positioned opposite each other to form an inner space. This provides an installation area for the combination of two drive methods, effectively preventing exposed components from interfering with the cockpit space. The first mounting plate 11 has a first mounting hole 11a, and the second mounting plate 12 has a second mounting hole 12a communicating with a sleeve 13. One end of the sleeve 13 is fixedly connected to the side of the second mounting plate 12 facing away from the first mounting plate 11, and the other end is connected to the vehicle body via a connector 14. This integrated design of the sleeve 13 and connector 14 provides rotational support for the inner shaft 31 of the foot pedal drive assembly 30 via the sleeve 13, and directly fixes it to the vehicle body via the connector 14. This eliminates the complex process of additional drilling or welding on the vehicle body required in traditional modifications, significantly improving the device's compatibility with different vehicle models. For example, for different vehicle models, only the matching connector 14 needs to be replaced to quickly fix the mounting bracket 10, which greatly reduces the modification cost and debugging difficulty.

[0023] This structure facilitates seamless compatibility between intelligent and manual operation. Specifically, when automatic system intervention is required (e.g., due to operator error leading to engine stall risk), motor 21 drives the output shaft to rotate, causing the vertically connected active swing arm 22 to swing synchronously. The contact element 23 at the end of the active swing arm 22 moves inward into the space, eventually contacting and applying a thrust to the driven rod 32 of the foot pedal drive assembly 30. The driven rod 32, under the thrust, rotates around the inner shaft 31, driving the clutch lever 34 to pull the clutch pedal via the force transmission plate 33, achieving precise control of the clutch pedal travel (e.g., slowly releasing the clutch to avoid stalling). During this process, the output angle of motor 21 can be precisely adjusted in conjunction with the vehicle's central processing unit via an encoder or controller, significantly improving control accuracy and intervention efficiency.

[0024] When trainees are training independently or when instructors need to intervene manually, trainees directly depress the clutch pedal. This triggers the clutch lever 34, which pulls the force transmission plate 33 in the opposite direction, driving the inner shaft 31 to rotate. This, in turn, causes the driven rod 32 to swing away from the contact member 23. At this time, the contact member 23 can move accordingly to avoid this movement, ensuring the smoothness of manual operation is not limited by the mechanical structure. This design retains the flexibility of traditional manual pedaling (such as the instructor's autonomous control of the clutch release rhythm) while providing backup support from the motor drive component, ensuring automatic correction in emergency situations.

[0025] The contact element 23 includes a positioning pin 231 and a rolling bearing 232. The positioning pin 231 is installed at the end of the active rocker arm 22, and the rolling bearing 232 is disposed on the positioning pin 231. This converts the contact transmission between the contact element 23 and the driven rod 32 from sliding friction to rolling friction, effectively reducing energy loss during transmission. At the same time, the rolling bearing 232 can withstand radial loads, avoiding wear caused by long-term reciprocating contact, extending the service life of the contact element 23, and ensuring the long-term reliability of the intelligent drive mode.

[0026] The first mounting plate 11 has two limiting posts 111 on its inner side. The two limiting posts 111 are respectively set at both ends of the swing stroke of the active swing rod 22. The limiting posts 111 physically limit the swing angle of the active swing rod 22, preventing the active swing rod 22 from exceeding the design stroke due to motor 21 overload or program mis-triggering, and avoiding rigid collision with the driven rod 32. This protects the active swing rod 22, driven rod 32 and other precision components from deformation or breakage, and significantly improves the safety of the device operation.

[0027] In the embodiments of this application, the assembly structure further includes an elastic assist component 40, one end of which is connected to the first mounting plate 11 and the other end is connected to the active swing arm 22, for elastically driving the active swing arm 22 to swing so that the abutment 23 moves away from the driven rod 32.

[0028] Preferably, the elastic assist component 40 includes a fixed shaft 41, an elastic element 42, and a push plate 43. The first mounting plate 11 extends outward along its plane to form an extension 112. The fixed shaft 41 is mounted on the extension 112. The push plate 42 is fixed on the active swing arm 22. A top shaft 431 is provided on the push plate 43. The two ends of the elastic element 42 abut against the fixed shaft 41 and the top shaft 431, respectively.

[0029] The elastic element 42 includes a spring tail seat 421, a telescopic rod 422, a compression spring 423, and a spring top seat 424. The telescopic rod 422 is connected between the spring tail seat 421 and the spring top seat 424. The compression spring 423 is fitted onto the outside of the telescopic rod 422. The spring tail seat 421 has a tail seat groove that mates with the fixed shaft 41. The spring top seat 424 has a top seat groove that mates with the top shaft 431.

[0030] The elastic assist component 20 provides the system with an automatic return function. After the intelligent drive mode is completed, the active swing arm 22 is driven to swing in the opposite direction by the elastic force, so that the contact member 23 is separated from the driven rod 32. This avoids the increase in manual operation resistance caused by the continuous pressure of the contact member 23 on the driven rod 32. At the same time, it pre-tightens for the next intelligent drive action to ensure the timeliness and accuracy of the transmission. Specifically, the telescopic rod 422 constrains the deformation direction of the compression spring 423 to prevent the spring from twisting and failing, and ensures that the direction of elastic force transmission is consistent with the reset direction of the active swing arm 22, thereby improving the smoothness of the reset process.

[0031] In the embodiments of this application, the first mounting plate 11 and the second mounting plate 12 are connected and fixed by a plurality of connecting posts 15 connected to the outer periphery. The plurality of connecting posts 15 form a ring-shaped reinforcing structure, which effectively improves the connection rigidity between the first mounting plate 11 and the second mounting plate 12 and prevents the motor 21 from being displaced due to vehicle vibration.

[0032] The axis of rotation of the active rocker arm 22 coincides with the axis of rotation of the inner shaft 31. This coincidence ensures that the swing trajectory of the active rocker arm 22 is completely aligned with the rotation trajectory of the driven rod 32, eliminating lateral forces during transmission, reducing wear between the driven rod 32 and the sleeve 13, improving transmission efficiency, and ensuring the accuracy of clutch pedal travel control in intelligent drive mode.

[0033] The connector 14 includes two fixing plates 141 welded to the sleeve 13. The end of the fixing plate 141 away from the sleeve is bent to form a mounting end plate 142. The mounting end plates 142 of the two fixing plates 141 are located on the same plane. The planar structure of the mounting end plate 142 increases the contact area with the vehicle body. The mounting end plates 142 are located on the same plane, which makes it easy to adjust the installation angle to adapt to the driver's side floor structure of different vehicle models, and significantly improves the versatility of the device.

[0034] In summary, this technical solution, through structural innovation and the integration of drive modes, has achieved systematic improvements in installation adaptability, operational compatibility, control precision, and safety assurance, providing key technical support for the upgrade of the master driving clutch device from manual assistance to intelligent collaboration.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
