Description

A single-motor range-extended power off-axis transmission device Technical Field

[0001] This utility model relates to the field of single-motor range-extended power off-axis technology, specifically a single-motor range-extended power off-axis transmission device. Background Technology

[0002] With the increasing prominence of energy and environmental issues, new energy vehicles have become the dominant direction for the development of transportation tools and have developed rapidly. At the same time, this has also led to many key technical issues, such as the relationship between driving range and energy consumption. Currently, the intermediate problem of pure electric vehicles is that the battery limits the driving range, which has led to the development of hybrid vehicles. From the current market application, the problem of driving range and energy loss still exists.

[0003] Existing off-axis transmission devices for new energy vehicle motors still have certain shortcomings in actual use: existing off-axis transmission devices usually use gears to transmit power in different directions. However, gear transmission lacks flexibility and is prone to accelerated wear in humid, high-temperature, or dusty environments, requiring additional sealing and protection measures. Based on the shortcomings of existing technology, this utility model designs a single-motor range-extended power off-axis transmission device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a single-motor range-extended power off-axis transmission device, which has the advantages of high flexibility and low wear resistance.

[0005] This utility model provides the following technical solution: a single-motor range-extended power off-axis transmission device, including a mounting frame. Two fixing rings are fixedly installed on the top of the mounting frame. A motor body is fixedly installed inside the two fixing rings. A transmission structure is fixedly installed at one end of the output shaft of the motor body. The transmission structure includes a connecting rod and two first transmission discs. A slotted plate is fixedly installed at one end of the connecting rod. A clamping plate is fitted inside the slotted plate. Fixing bolts are threaded on both sides of the outer surface of the slotted plate. The two fixing bolts are threadedly connected to the clamping plate. A connecting plate is fixedly installed at one end of the clamping plate. A fixing rod is fixedly installed at one end of the connecting plate. One of the first transmission discs is fixed to the fixing rod. Three movable bent columns are movably installed between the two first transmission discs. A transmission rod is fixedly installed on one side of the other first transmission disc.

[0006] By adopting the above technical solution and through the transmission structure, during device operation, the card plate is inserted into the slot plate and then fixed with two fixing bolts. The transmission rod then connects to the structure to be transmitted. Driven by the motor body, its output shaft rotates the connecting rod. Through the connection of the fixing rod, one of the first transmission discs can rotate. Due to the movable connection between the three movable bent columns and the two first transmission discs, the rotation of one first transmission disc can drive the other first transmission disc to rotate simultaneously. This allows the transmission rod to drive the structure to rotate, thus completing the transmission. Therefore, this device replaces traditional gears with first transmission discs, avoiding excessive wear. Furthermore, the direction of the two first transmission discs can be arbitrarily changed to alter the transmission angle, improving the flexibility of the device.

[0007] As a preferred embodiment of the present invention, a steering structure is fixedly installed on one side of the outer surface of the mounting frame, and the steering structure includes a sliding disc.

[0008] By adopting the above technical solution, the sliding disc can provide support for the rotating column, making its rotation smoother.

[0009] As a preferred embodiment of this utility model, a fixing groove is fixedly installed on the outer surface of the sliding disk.

[0010] By adopting the above technical solution and setting the fixing groove, the rotating column can be fixed by the fixing groove no matter which direction it rotates to.

[0011] As a preferred embodiment of this utility model, a rotating column is slidably installed inside the sliding disk, and a collar shaft is fixedly installed at the end of the rotating column.

[0012] By adopting the above technical solution, the transmission rod can be supported by the rotating column, forming a triangle with it to improve stability.

[0013] As a preferred embodiment of this utility model, the collar is sleeved on the outer surface of the transmission rod.

[0014] By adopting the above technical solution, the collar shaft can be fitted onto the outside of the transmission rod, making its rotation smoother and also limiting its movement.

[0015] As a preferred embodiment of this utility model, an extension plate is fixedly installed on one side of the outer surface of the rotating column.

[0016] By adopting the above technical solution, the rotating column is positioned on one side of the fixed groove, which facilitates subsequent fixing of the rotating column.

[0017] As a preferred embodiment of this utility model, the extension plate is internally threaded with a fixing screw, which can be rotated to contact the fixing groove.

[0018] By adopting the above technical solution, and by setting the fixing screw, when the rotating column rotates to a certain direction, the fixing screw is rotated to make it contact the inside of the fixing groove, thus forming a fixation.

[0019] As a preferred embodiment of this utility model, a support column is fixedly installed on the top of the mounting frame, and the support column is rotatably connected to the connecting rod.

[0020] By adopting the above technical solution, the connecting rod is provided with limiting support.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This single-motor range-extended power off-axis transmission device, through its transmission structure, allows the insertion of a clamping plate into a slot plate during operation. This plate is then fixed with two bolts and connected to the structure to be transmitted via a transmission rod. Driven by the motor body, its output shaft rotates the connecting rod. Through the connection of the fixed rod, one first transmission disc rotates. Because three movable curved columns are connected to two first transmission discs, the rotation of one first transmission disc drives the simultaneous rotation of the other, thus enabling the transmission rod to rotate the transmitted structure, thereby completing the transmission. This device replaces traditional gears with first transmission discs, avoiding excessive wear. Furthermore, the direction of the two first transmission discs can be arbitrarily changed to alter the transmission angle, improving the device's flexibility.

[0023] 2. This single-motor range-extended power off-axis transmission device, through its transmission structure and steering structure, allows for a change in transmission direction when necessary. This is achieved by loosening the fixing screw, then loosening the two fixing bolts, and re-inserting the card plate into the slot plate by changing its orientation. This changes the direction of the transmission rod. Then, by rotating the fixing screw again, the rotating column is fixed in the sliding disc, thereby changing the transmission direction of the transmission rod. Attached Figure Description

[0031] Please refer to Figures 1-5. A single-motor range-extended power off-axis transmission device includes a mounting frame 1. Two fixing rings 2 are fixedly installed on the top of the mounting frame 1. A motor body 3 is fixedly installed inside the two fixing rings 2. A transmission structure 4 is fixedly installed at one end of the output shaft of the motor body 3. The transmission structure 4 includes a connecting rod 41 and two first transmission discs 47. A slotted plate 42 is fixedly installed at one end of the connecting rod 41. A clamping plate 43 is clamped inside the slotted plate 42. Fixing bolts 44 are threaded on both sides of the outer surface of the slotted plate 42. The two fixing bolts 44 are threadedly connected to the clamping plate 43. A connecting plate 45 is fixedly installed at one end of the clamping plate 43. A fixing rod 46 is fixedly installed at one end of the connecting plate 45. One of the first transmission discs 47 is fixed to the fixing rod 46. Three movable bent columns 48 are movably installed between the two first transmission discs 47. A transmission rod 49 is fixedly installed on one side of the other first transmission disc 47.

[0032] Please refer to Figures 4-5. A steering structure 5 is fixedly mounted on one side of the outer surface of the mounting frame 1. The steering structure 5 includes a sliding disk 51. A fixing groove 52 is fixedly mounted on the outer surface of the sliding disk 51. A rotating column 53 is slidably mounted inside the sliding disk 51, and a collar shaft 54 ​​is fixedly mounted at the end of the rotating column 53. The collar shaft 54 ​​is sleeved on the outer surface of the transmission rod 49. An extension plate 55 is fixedly mounted on one side of the outer surface of the rotating column 53. A fixing screw 56 is threaded inside the extension plate 55, and the fixing screw 56 can contact the fixing groove 52 by rotation.

[0033] When it is necessary to change the transmission direction, the fixing screw 56 is loosened, and then the two fixing bolts 44 are loosened. The direction of the clamping plate 43 is changed and the direction of the slot plate 42 is re-inserted. At this time, the direction of the transmission rod 49 can be changed. Then, the fixing screw 56 is rotated again to fix the rotating column 53 in the sliding plate 51, thereby changing the transmission direction of the transmission rod 49.

[0034] Please refer to Figure 1-2. A support column 6 is fixedly installed on the top of the mounting frame 1, and the support column 6 is rotatably connected to the connecting rod 41.

[0035] The connecting rod 41 can be supported by the support column 6.

[0036] Working principle: When a single-motor range-extended power off-axis transmission device is used, firstly, during device operation, the clamping plate 43 is inserted into the slot plate 42 and then fixed with two fixing bolts 44. Then, it is connected to the structure to be transmitted via the transmission rod 49. Driven by the motor body 3, its output shaft drives the connecting rod 41 to rotate. Through the connection of the fixing rod 46, one first transmission disc 47 can rotate. Due to the movable connection of three movable bent columns 48 to the two first transmission discs 47, the rotation of one first transmission disc 47 can drive the other first transmission disc 47 to rotate simultaneously, thereby enabling the transmission rod 49 to drive the transmitted structure to rotate, thus completing the transmission. When it is necessary to change the transmission direction, the fixing screw 56 is loosened, followed by the loosening of the two fixing bolts 44. By changing the direction of the clamping plate 43 and re-inserting it into the slot plate 42, the direction of the transmission rod 49 can be changed. Then, by rotating the fixing screw 56 again, the rotating column 53 is fixed in the sliding disc 51, thereby changing the transmission direction of the transmission rod 49.
