One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

1. Due to the use of the upper mounting plate, buffer assembly, shock absorbing assembly, lower mounting plate, pin shaft and support block, when the electric bicycle equipped with the shock absorbing device is traveling on a bumpy road section, the vibration caused by the bumpy road section will continuously generate periodic pressure of different frequencies on the upper mounting plate. At this time, the upper mounting plate will intermittently compress the buffer assembly, so that the buffer assembly will first produce a certain shock absorbing effect on the electric bicycle. When the road section encountered by the electric bicycle is more bumpy, the periodic pressure of different frequencies continuously generated by the electric bicycle on the upper mounting plate will also increase. At this time, when the buffer assembly is compressed to a certain extent, the upper mounting plate will drive the two groups of shock absorbing assemblies to move toward the lower mounting plate. As the two shock-absorbing components move toward the lower mounting plate, the pins at both ends of the two shock-absorbing components will slide downward in the slide groove. When the pins slide to the bottom of the slide groove, the two shock-absorbing components will begin to participate in the shock absorption of the electric bicycle. Therefore, through the cooperation between the buffer component and the shock-absorbing component, the riding comfort of the electric bicycle will not be affected when riding on a bumpy road. At the same time, the electric bicycle equipped with the shock-absorbing device can be used for riding on roads with different degrees of bumpiness, thereby greatly improving the practicality of the shock-absorbing device.

2. Due to the arrangement of the support plate, the connecting rod, the first spring, the first telescopic rod, the first connecting head, the first fixed seat and the second fixed seat, and the first connecting heads at both ends of the first telescopic rod are swingably connected to the rollers of the first fixed seat and the second fixed seat respectively, the first spring and the first telescopic rod in the buffer assembly can be compressed normally between the upper mounting plate and the lower mounting plate. When the electric bicycle encounters a bumpy road section and the buffer assembly is involved in the shock absorption work, the upper mounting plate will intermittently compress the first spring and the first telescopic rod. At this time, the first spring in a compressed state will produce a certain elastic force, and then can produce a certain buffering effect on the upper mounting plate, so to a certain extent, it can play a certain shock absorption effect when the electric bicycle is riding on a bumpy road section. When the first spring is in a compressed state, the first telescopic rod can prevent the first spring from deforming, and then can play a certain protective role on the first spring.

3. Due to the use of the guide plate, shock absorbing mechanism, second connector, second spring, second telescopic rod, third fixed seat and fourth fixed seat, and the second connectors at both ends of the second telescopic rod are swingably connected to the rollers of the third fixed seat and the fourth fixed seat respectively, the second spring and the second telescopic rod in the shock absorbing assembly can be compressed normally between the upper mounting plate and the lower mounting plate. When the electric bicycle encounters a severely bumpy road section, causing the shock absorbing assembly to participate in the shock absorbing work, the upper mounting plate 1 will intermittently compress the second spring and the second telescopic rod. At this time, the second spring in a compressed state will produce a certain elastic force, and then can produce a certain buffering effect on the upper mounting plate, so to a certain extent, it can play a certain shock absorbing effect when the electric bicycle is riding on a bumpy road section. When the second spring is in a compressed state, the second telescopic rod can prevent the second spring from deforming, and then can play a certain protective role on the second spring.

DETAILED DESCRIPTION

The embodiment of the present application provides a shock absorbing device for an electric bicycle, thereby solving the technical problem that in the prior art solutions, the shock absorbing structure on the electric bicycle is mostly relatively simple. When the rider encounters a bumpy road section, the shock absorbing structure on the electric bicycle cannot achieve a good shock absorbing effect, which affects the rider's comfort when riding the electric bicycle.

The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

A shock absorbing device for an electric bicycle, as shown in FIG1, comprises an upper mounting plate 1, a buffering assembly 2 for buffering the upper mounting plate 1, a shock absorbing assembly 3 for shock absorbing the upper mounting plate 1, a lower mounting plate 4 mounted on the electric bicycle, a pin 5 arranged at both ends of the shock absorbing assembly 3, and a support block 6 arranged on the lower mounting plate 4. The buffering assembly 2 is arranged between the upper mounting plate 1 and the lower mounting plate 4. Two groups of shock absorbing assemblies 3 are arranged symmetrically on the upper mounting plate 1. A slide groove 61 is arranged on the support block 6. The pin 5 slides on the slide groove 61.

The upper mounting plate 1 and the lower mounting plate 4 are preferably made of stainless steel. The buffer assembly 2 is fixedly connected between the upper mounting plate 1 and the lower mounting plate 4. Two groups of shock absorbing assemblies 3 symmetrically arranged with the buffer assembly 2 are fixedly connected to the bottom of the upper mounting plate 1. Both ends of the bottom of each group of shock absorbing assemblies 3 are fixedly connected to pins 5. The top of the lower mounting plate 4 corresponding to each group of pins 5 is fixedly connected to support blocks 6. The top of each group of support blocks 6 is fixedly connected to two groups of symmetrically arranged slide grooves 61. Both ends of each group of pins 5 slide in the corresponding two groups of slide grooves 61. Long waist holes are provided on the upper mounting plate 1 and the lower mounting plate 4. Since long waist holes are provided on the upper mounting plate 1 and the lower mounting plate 4, it is convenient for the staff to install the shock absorbing device on the electric bicycle through the long waist holes.

Due to the arrangement of the upper mounting plate 1, the buffer assembly 2, the shock absorbing assembly 3, the lower mounting plate 4, the pin 5 and the support block 6, when the electric bicycle equipped with the shock absorbing device is traveling on a bumpy road section, the vibration of the electric bicycle caused by the bumpy road section will continuously generate periodic pressure of different frequencies on the upper mounting plate 1. At this time, the upper mounting plate 1 will intermittently compress the buffer assembly 2, so that the buffer assembly 2 will first produce a certain shock absorbing effect on the electric bicycle. When the road section encountered by the electric bicycle is more bumpy, the periodic pressure of different frequencies continuously generated by the electric bicycle on the upper mounting plate 1 will also increase. At this time, when the buffer assembly 2 is compressed to a certain extent, the upper mounting plate 1 will drive the two groups of shock absorbing assemblies 3 to move toward the lower mounting plate 4. During the movement of the two shock absorbing components 3 toward the lower mounting plate 4, the pin shafts 5 at both ends of the two shock absorbing components 3 will slide downward in the slide groove 61. When the pin shafts 5 slide to the bottom of the slide groove 61, the two shock absorbing components 3 will begin to participate in the shock absorption of the electric bicycle. Therefore, through the mutual cooperation of the buffer component 2 and the shock absorbing component 3, the riding comfort of the electric bicycle will not be affected when riding on a bumpy road section. At the same time, the electric bicycle equipped with the shock absorbing device can be suitable for riding on roads with different degrees of bumpiness, thereby greatly improving the practicality of the shock absorbing device.

As shown in FIG2 , the buffer assembly 2 includes a support plate 21, a connecting rod 22 disposed on the lower mounting plate 4, a first spring 23 for buffering the upper mounting plate 1, a first telescopic rod 24 for limiting the first spring 23, first connectors 25 disposed at both ends of the first telescopic rod 24, a first fixed seat 26 disposed on the upper mounting plate 1, and a second fixed seat 27 disposed on the support plate 21. The support plate 21 is disposed on the connecting rod 22. The first spring 23 is disposed around the first telescopic rod 24. Both ends of the first spring 23 are respectively connected to the corresponding first connectors 25. Two groups of first connectors 25 are respectively hinged on the first fixed seat 26 and the second fixed seat 27.

Three groups of connecting rods 22 arranged in a linear array are fixedly connected to the bottom of the support plate 21. The three groups of connecting rods 22 are fixedly connected to the top of the lower mounting plate 4. The first telescopic rod 24 is fixedly connected to the first connecting head 25 at both ends. The first fixed seat 26 is fixedly connected to the bottom of the upper mounting plate 1. The second fixed seat 27 is fixedly connected to the top of the support plate 21. The two ends of the first spring 23 are fixedly connected to the corresponding first connecting head 25. The first fixed seat 26 and the second fixed seat 27 are both provided with rollers adapted to the first connecting head 25. The two groups of first connecting heads 25 are swingably connected to the rollers of the first fixed seat 26 and the second fixed seat 27.

Due to the arrangement of the support plate 21, the connecting rod 22, the first spring 23, the first telescopic rod 24, the first connector 25, the first fixed seat 26 and the second fixed seat 27, the first connectors 25 at both ends of the first telescopic rod 24 are respectively swingably connected to the rollers of the first fixed seat 26 and the second fixed seat 27, so that the first spring 23 and the first telescopic rod 24 in the buffer assembly 2 can be normally compressed between the upper mounting plate 1 and the lower mounting plate 4. When the electric bicycle encounters a bumpy section and the buffer assembly 2 participates in the shock absorption work, the upper mounting plate 1 will intermittently compress the first spring 23 and the first telescopic rod 24. At this time, the first spring 23 in the compressed state will produce a certain elastic force, and then can produce a certain buffering effect on the upper mounting plate 1, so to a certain extent, it can play a certain shock absorption effect when the electric bicycle is riding on a bumpy section. When the first spring 23 is in a compressed state, the first telescopic rod 24 can prevent the first spring 23 from deforming, and then can play a certain protective role on the first spring 23.

As shown in Figures 3 and 4, the shock absorbing assembly 3 includes a guide plate 31 and a shock absorbing mechanism 32 for shock absorbing the upper mounting plate 1. Three groups of shock absorbing mechanisms 32 arranged in a linear array are arranged on the guide plate 31. The three groups of shock absorbing mechanisms 32 are all connected to the upper mounting plate 1. Pins 5 are arranged at both ends of the guide plate 31.

The shock absorbing mechanism 32 includes a second connector 321, a second spring 322 for buffering the upper mounting plate 1, a second telescopic rod 323 for limiting the second spring 322, a third fixing seat 324 arranged on the upper mounting plate 1, and a fourth fixing seat 325 arranged on the guide plate 31. Both ends of the second telescopic rod 323 are connected to the second connector 321. The second spring 322 is arranged around the second telescopic rod 323. Both ends of the second spring 322 are respectively connected to the corresponding second connector 321. Two sets of second connectors 321 are respectively hinged on the third fixing seat 324 and the fourth fixing seat 325.

Three groups of shock absorbing mechanisms 32 arranged in a linear array are fixedly connected to the top of the guide plate 31. The three groups of shock absorbing mechanisms 32 are fixedly connected to the bottom of the upper mounting plate 1. Pins 5 are fixedly connected to both ends of the guide plate 31. The third fixed seat 324 is fixedly connected to the bottom of the upper mounting plate 1. The fourth fixed seat 325 is fixedly connected to the top of the guide plate 31. The second connecting head 321 is fixedly connected to both ends of the second telescopic rod 323. The third fixed seat 324 and the fourth fixed seat 325 are both provided with rollers adapted to the second connecting head 321. The two groups of second connecting heads 321 are swingably connected to the rollers of the third fixed seat 324 and the fourth fixed seat 325, respectively.

Due to the arrangement of the guide plate 31, the shock absorbing mechanism 32, the second connector 321, the second spring 322, the second telescopic rod 323, the third fixing seat 324 and the fourth fixing seat 325, and the second connectors 321 at both ends of the second telescopic rod 323 are swingably connected to the rollers of the third fixing seat 324 and the fourth fixing seat 325, respectively, the second spring 322 and the second telescopic rod 323 in the shock absorbing assembly 3 can be normally compressed between the upper mounting plate 1 and the lower mounting plate 4. When the electric bicycle encounters a serious bumpy section and the shock absorbing assembly 3 participates in the shock absorbing work, the upper mounting plate 1 will intermittently compress the second spring 322 and the second telescopic rod 323, and the second spring 322 in the compressed state will produce a certain elastic force, thereby producing a certain buffering effect on the upper mounting plate 1, so that to a certain extent, it can play a certain shock absorbing effect when the electric bicycle is riding on a bumpy section. When the second spring 322 is in a compressed state, the second telescopic rod 323 can prevent the second spring 322 from deforming, thereby protecting the second spring 322 to a certain extent.
