Description

Technical Field

[0001] This utility model relates to the field of differential technology, and in particular to a lubrication mechanism for a built-in differential in an electric remote control device. Background Technology

[0002] A car differential is a mechanism that allows the left and right (or front and rear) drive wheels to rotate at different speeds. It mainly consists of left and right half-shaft gears, two planetary gears, and a gear carrier. Its function is to ensure that the left and right wheels rotate at different speeds when the car is turning or driving on uneven surfaces, thus guaranteeing that both drive wheels undergo pure rolling motion.

[0003] Normally, when lubricating a differential, the lubrication pipe is fixed inside the differential housing, and oil can only be added to the internal differential through the lubrication pipe. In order to prevent oil from splashing out, a sealing cap needs to be twisted to achieve this. Since the sealing cap is small in size, it is easy to lose. Therefore, an electric remote control device with a built-in differential lubrication mechanism is needed to solve the above problems. Utility Model Content

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this embodiment is a lubrication mechanism for a built-in differential in an electric remote control device, comprising:

[0031] The main component includes a first housing 1 and a second housing 18, with the second housing 18 fixedly mounted on the back of the first housing 1.

[0032] The lubrication component includes an oil injection pipe 2, a first groove 4, a second groove 3, a slider 5, a cover plate 6, a sealing cover 9, a rubber strip 12, a spring 13, a support frame 11, a push rod 8, a first oil injection port 7, and a second oil injection port 10.

[0033] An oil injection pipe 2 is fixedly installed on the inner wall of the first housing 1. A first groove 4 and a second groove 3 are provided inside the oil injection pipe 2. A slider 5 is slidably installed in the first groove 4. A cover plate 6 is fixedly installed on one side of the slider 5. A sealing cover 9 overlaps the lower end face of the cover plate 6. A rubber strip 12 is fixedly installed on the lower end face of the sealing cover 9. A spring 13 is sleeved on the surface of the rubber strip 12. A support frame 11 is fixedly installed inside the oil injection pipe 2.

[0034] When the slider 5 slides into the second groove 3 and moves away from the outermost edge of the first groove 4, the first oil inlet 7 and the second oil inlet 10 are in a vertically opposite position, so as to inject lubricating oil downward. Under the constraint of the spring 13, the sealing cover 9 and the cover plate 6 can be pushed to fit stably, making oil injection more convenient and preventing oil from splashing out.

[0035] The first groove 4 and the second groove 3 are connected, and the surface of the cover plate 6 is slidably fitted into the oil injection pipe 2.

[0036] The cover plate 6 slides within the oil injection pipe 2 via the first groove 4 and the second groove 3.

[0037] A push rod 8 is fixedly installed on the upper end face of the cover plate 6, and the bottom end of the push rod 8 is fixedly installed at the center of the upper end face of the cover plate 6.

[0038] The rotation direction of the cover plate 6 can be easily controlled by the push rod 8;

[0039] The upper end face of the cover plate 6 is provided with a first oil inlet 7, and the inner wall of the sealing cover 9 is provided with a second oil inlet 10.

[0040] The bottom end of the spring 13 is fixedly installed on the upper end face of the support frame 11, and the top end of the spring 13 is fixedly installed on the lower end face of the sealing cover 9.

[0041] Working principle: When the operator needs to inject lubricating oil into the oil injection pipe 2, the push rod 8 controls the cover plate 6 to press down, which in turn moves the sealing cover 9 downwards. At the same time, the rubber strip 12 and spring 13 are squeezed. During this process, the slider 5 slides vertically downwards in the first groove 4. When the slider 5 has completely slid into the bottom of the first groove 4, the push rod 8 controls the cover plate 6 to rotate to the right, directly entering the second groove 3, and sliding the slider 5 to the far right of the second groove 3. At this time, the centers of the first oil injection port 7 in the cover plate 6 and the second oil injection port in the sealing cover 9 are aligned. Then, the staff can inject the lubricating oil into the oil injection pipe 2. Due to the restriction of the cover plate 6 by the second groove 3, it is more stable when the first oil injection port 7 and the second oil injection port 10 are aligned, which makes it easier for the staff to inject the lubricating oil into the oil injection pipe 2. After completion, the push rod 8 is used to control the cover plate 6 to rotate towards the first groove 4, so that the slider 5 enters the first groove 4 again. At this time, the first oil injection port 7 and the second oil injection port 10 are misaligned. Through the contact between the cover plate 6 and the sealing cover 9, the stability of the lubricating oil in the oil injection pipe 2 can be guaranteed, preventing it from splashing out.

[0042] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, and the lubrication component further includes an oil reservoir 14, an oil delivery pipe 15, an oil-absorbing sponge 16, an oil delivery ball 17, and a rotating groove;

[0043] An oil storage chamber 14 is fixedly installed at the bottom end of the oil injection pipe 2. An oil delivery pipe 15 is fixedly installed on the inner wall of the oil storage chamber 14. An oil-absorbing sponge 16 is fixedly installed inside the oil delivery pipe 15. An oil delivery ball 17 is attached to one side of the oil-absorbing sponge 16. A rotating groove is opened inside the oil delivery pipe 15. The surface of the oil delivery ball 17 rotates inside the oil delivery pipe 15 through the rotating groove.

[0044] When the lubricating oil enters the oil reservoir 14, it can be temporarily stored. The lubricating oil is evenly applied to the surface of the oil supply ball 17 using the oil-absorbing sponge 16. At the same time, the inside of the oil supply ball 17 can rotate when it comes into contact with the differential.

[0045] The oil injection pipe 2 is connected to the oil storage chamber 14, and the oil storage chamber 14 is connected to the oil delivery pipe 15.

[0046] Working principle: First, when the operator injects lubricating oil into the oil injection pipe 2, the oil injection pipe 2 can temporarily store the lubricating oil through its connection with the oil reservoir 14. The oil can be transported from one end of the oil reservoir 14 to one end of the oil delivery ball 17 through the oil absorption sponge 16. Through the contact between the sponge and the oil delivery pipe 15, the lubricating oil can be evenly coated on the surface of the oil delivery ball 17. At the same time, the oil delivery ball 17 evenly transports the lubricating oil into the differential, avoiding the generation of a large amount of foam when the lubricating oil is running at high speed, which would reduce the lubrication performance.

[0047] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
