Description

Technical Field

[0001] This utility model relates to the field of transmission mechanical structure for new energy vehicles, and in particular to a drive mechanism for automatic displacement of the shaft system of a new energy transmission. Background Technology

[0002] The new energy vehicle transmission shaft system is the general term for the core transmission components inside the transmission of a new energy vehicle. It mainly consists of input shafts, output shafts, intermediate shafts, gear sets, bearings, and other components. Its core function is to convert the power output from the motor into speed and torque, and drive the vehicle through precise power transmission. The automatic displacement drive mechanism is an adaptive transmission adjustment device designed for the new energy vehicle transmission shaft system. Its core consists of drive components, transmission connectors, clamping and positioning components, and control units. Through the synergy of mechanical transmission and automatic control, it realizes the position adjustment, precise positioning, and dynamic fixation of the shaft system components. It can adjust the shaft system transmission state in real time according to changes in vehicle driving conditions to ensure the adaptability and stability of power transmission. The driving conditions of new energy vehicles are complex and varied, and different conditions have significantly different requirements for the transmission ratio and torque output of the shaft system. Automatic displacement can enable the shaft system to switch to the optimal transmission state in real time, avoiding power waste or insufficient performance caused by a fixed transmission ratio.

[0003] The use of automatic displacement drive mechanisms for new energy transmission shafts must follow an automated process of working condition identification, command issuance, displacement execution, and status feedback. Traditional automatic displacement drive mechanisms for new energy transmission shafts often use a single pin-type fixing method, which has relatively low positioning accuracy and is prone to shaft position displacement under high torque transmission or vehicle bumpy conditions. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a drive mechanism for automatic displacement of the shaft system in a new energy transmission, which aims to improve the problem of shaft system position misalignment that easily occurs under high torque transmission or vehicle bumpy conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic displacement drive mechanism for a new energy gearbox shaft system, comprising a housing, a sliding plate slidably connected inside the housing, a fixing block fixedly connected to the outer wall of the sliding plate, a motor fixedly connected inside the fixing block, a lead screw fixedly installed at the output end of the motor, a connecting frame threadedly connected to the outer wall of the lead screw, a fixing plate fixedly connected to the outer wall of the sliding plate, a connecting rod rotatably connected to the outer wall of the connecting frame, a clamping frame rotatably connected to the outer wall of the connecting rod, a clamping ring fixedly connected to the outer wall of the clamping frame, and a transmission component rotatably connected to the outer wall of the clamping ring, the transmission component being used to transmit force.

[0006] The above technical solution involves starting the motor to rotate the lead screw, which in turn moves the connecting frame, causing the connecting rod to rotate, and then the clamping frame to rotate, thereby releasing the output shaft. This significantly improves positioning stability and accuracy, ensures transmission reliability, and reduces the difficulty and intensity of manual operation. When clamping is required, the lead screw is rotated in the opposite direction to move the connecting frame toward the fixed block, which in turn rotates the connecting rod, causing the clamping rings on both sides to move toward each other and center. The outer shell restricts the transmission components, ensuring that the position of the transmission components does not change.

[0007] Preferably, the transmission assembly includes an output shaft, the outer wall of which is rotatably connected to the outer wall of the clamping ring, a gear one is fixedly connected to the outer wall of the output shaft, a gear two is meshed with the tooth end of the gear one, and a transmission shaft is fixedly connected inside the gear two.

[0008] Preferably, the outer wall of the lead screw is rotatably connected to the inside of the fixed block, and the outer wall of the lead screw is rotatably connected to the inside of the fixed plate.

[0009] Preferably, the outer wall of the clamping frame is rotatably connected to the inside of the slide plate, and the outer wall of the connecting frame is connected to the outer wall of the fixed plate.

[0010] Preferably, the outer wall of the connecting frame is slidably connected to the outer wall of the slide plate, and the outer wall of the connecting frame is connected to the outer wall of the fixing block.

[0011] Preferably, a fixing frame is fixedly connected to the outer wall of the housing, an electric push rod is rotatably connected inside the fixing frame, a connecting rod is rotatably connected to the output end of the electric push rod, a fixing rod is rotatably connected inside the connecting rod, a bracket is rotatably connected inside the connecting rod, and a through rod is rotatably connected inside the bracket.

[0012] Preferably, the outer wall of the fixing rod is fixedly connected to the outer wall of the outer shell, and the outer wall of the through rod is slidably connected to the inside of the outer shell.

[0013] Preferably, the outer wall of the through rod is fixedly connected to the outer wall of the fixing block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the starter motor drives the lead screw to rotate, which in turn drives the connecting frame to move, thereby driving the connecting rod to rotate, which in turn drives the clamp frame to rotate, thereby releasing the output shaft. Therefore, the positioning stability and accuracy can be significantly improved, the transmission reliability can be guaranteed, and the difficulty and intensity of manual operation can be reduced.

[0015] 2. In this utility model, the electric push rod is activated to drive the connecting rod to move, which in turn drives the bracket to move, thereby driving the through rod to move, and then pushing the fixed block to move. Since the sliding plate slides inside the outer shell, and the clamping ring holds the output shaft tightly, the meshing between gear one and gear two is made tighter, which can improve transmission efficiency, reduce energy consumption, and also avoid abnormal damage to the gear tooth surface.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an automatic displacement drive mechanism for a new energy gearbox shaft system, comprising a housing 1, a sliding plate 2 slidably connected inside the housing 1, a fixing block 3 fixedly connected to the outer wall of the sliding plate 2, a motor 4 fixedly connected inside the fixing block 3, a lead screw 5 fixedly mounted at the output end of the motor 4, a connecting frame 6 threadedly connected to the outer wall of the lead screw 5, a fixing plate 7 fixedly connected to the outer wall of the sliding plate 2, a connecting rod 8 rotatably connected to the outer wall of the connecting frame 6, a clamping frame 9 rotatably connected to the outer wall of the connecting rod 8, a clamping ring 10 fixedly connected to the outer wall of the clamping frame 9, and a transmission component rotatably connected to the outer wall of the clamping ring 10 for transmitting force; the outer wall of the lead screw 5 is rotatably connected to the inside of the fixing block 3, and the outer wall of the lead screw 5 is rotatably connected to the inside of the fixing plate 7; the outer wall of the clamping frame 9 is rotatably connected to the inside of the sliding plate 2, and the outer wall of the connecting frame 6 is connected to the outer wall of the fixing plate 7; the outer wall of the connecting frame 6 is slidably connected to the outer wall of the sliding plate 2, and the outer wall of the connecting frame 6 is connected to the outer wall of the fixing block 3; Specifically, firstly, the motor 4 is started, driving the lead screw 5 to rotate, which in turn moves the connecting frame 6. The fixing block 3 restricts the motor 4 and lead screw 5, ensuring their positions do not change. Simultaneously, the fixing plate 7 restricts the lead screw 5, ensuring its position does not change. The sliding plate 2 restricts the connecting frame 6, ensuring that the force driving the connecting frame 6 to rotate is converted into a linear motion force, thereby driving the connecting rod 8 to rotate. The connecting rod 8 restricts the clamping frame 9, ensuring that the connecting rod 8, while being driven by the connecting frame 6, synchronously drives the clamping frame 9. The rotation of the shaft causes the clamping frame 9 to rotate, which in turn fixes the clamping ring 10, ensuring that the clamping ring 10 and the clamping frame 9 rotate simultaneously, thereby releasing the output shaft 11. This significantly improves positioning stability and accuracy, ensures transmission reliability, and reduces the difficulty and intensity of manual operation. When clamping is required, the reverse rotation of the lead screw 5 drives the connecting frame 6 to move towards the fixed block 3, thereby driving the connecting rod 8 to rotate, causing the clamping rings 10 on both sides to move towards each other and center. The outer shell 1 restricts the transmission components, ensuring that the position of the transmission components does not change.

[0020] Reference Figure 1 and Figure 2 The transmission assembly includes an output shaft 11, the outer wall of the output shaft 11 is rotatably connected to the outer wall of the clamping ring 10, a gear 12 is fixedly connected to the outer wall of the output shaft 11, a gear 13 is meshed with the tooth end of the gear 12, and a transmission shaft 14 is fixedly connected inside the gear 13. Specifically, the output shaft 11 restricts the gear 12, ensuring that the output shaft 11 rotates while driving the gear 12 to rotate, which in turn drives the gear 13 to rotate. Since the gear 13 is fixed to the outer wall of the transmission shaft 14, it synchronously drives the transmission shaft 14 to rotate, thereby achieving the effect of transmitting force.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A fixing frame 15 is fixedly connected to the outer wall of the outer casing 1. An electric push rod 16 is rotatably connected inside the fixing frame 15. A connecting rod 18 is rotatably connected to the output end of the electric push rod 16. A fixing rod 17 is rotatably connected inside the connecting rod 18. A bracket 19 is rotatably connected inside the connecting rod 18. A through rod 20 is rotatably connected inside the bracket 19. The outer wall of the fixing rod 17 is fixedly connected to the outer wall of the outer casing 1. The outer wall of the through rod 20 is slidably connected to the inside of the outer casing 1. The outer wall of the through rod 20 is fixedly connected to the outer wall of the fixing block 3. Specifically, the electric push rod 16 is first activated to move the connecting rod 18, which in turn moves the bracket 19. The fixed frame 15 restricts and supports the electric push rod 16 to prevent it from falling during operation. The outer shell 1 also restricts the fixed frame 15 to prevent it from falling. The fixed rod 17 restricts the connecting rod 18 to ensure that the connecting rod 18 rotates around the central axis of the fixed rod 17 without deviating during movement. This causes the through rod 20 to move. The outer shell 1 restricts the through rod 20, ensuring that the force of rotation of the through rod 20 when driven by the bracket 19 is converted into a linear motion force, which in turn pushes the fixed block 3 to move. Since the sliding plate 2 slides inside the outer shell 1, and the clamping ring 10 clamps the output shaft 11, the meshing between gear 12 and gear 2 13 becomes tighter, which can improve transmission efficiency, reduce energy consumption, and prevent abnormal damage to the gear tooth surface.

[0022] Working principle: When it is necessary to release, the motor 4, which is restricted by the fixed block 3, is started first to drive the lead screw 5 to rotate, which in turn drives the connecting frame 6 to move, thereby driving the connecting rod 8 to rotate, and then driving the clamping frame 9 to rotate, thereby releasing the output shaft 11. Therefore, the positioning stability and accuracy can be significantly improved, the transmission reliability can be guaranteed, and the difficulty and intensity of manual operation can be reduced. When it is necessary to tighten, the lead screw 5 is rotated in the opposite direction to drive the connecting frame 6 to move towards the fixed block 3, which in turn drives the connecting rod 8 to rotate, thereby causing the clamping rings 10 on both sides to move towards the center. When the gap between gear 12 and gear 23 is too large, the electric push rod 16, which is restricted by the fixed frame 15, is activated first to drive the connecting rod 18 to move, which in turn drives the bracket 19 to move, thereby driving the through rod 20 to move, and then pushing the fixed block 3 to move. Since the slide plate 2 slides inside the outer shell 1, and the clamping ring 10 clamps the output shaft 11, the meshing between gear 12 and gear 23 becomes tighter, which can improve transmission efficiency, reduce energy consumption, and also avoid abnormal damage to the gear tooth surface. This mechanism can not only significantly improve positioning stability and accuracy, ensure transmission reliability, and reduce the difficulty and intensity of manual operation, but also improve transmission efficiency, reduce energy consumption, and avoid abnormal damage to gear tooth surfaces.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
