[0001] The utility model belongs to the technical field of scooters, in particular to a rear wheel shock absorbing mechanism of a scooter. Background Art

[0002] With the progress of society, people pay more and more attention to environmental protection and green travel. In order to meet the short-distance travel needs of drivers, various scooters have emerged. Scooters are suitable for use by people of all ages because of their moderate speed, easy to learn and easy to operate, and brake devices. They are especially popular among teenagers. Since scooters are prone to bumps when passing through uneven roads, affecting safe driving and comfort, it is necessary to set a shock-absorbing mechanism on the scooter. However, most scooters on the market now only have shock-absorbing mechanisms for the front wheels, while most of the rear wheels of scooters do not have shock-absorbing mechanisms.

[0015] The prominent and beneficial technical effects of the present utility model compared with the prior art are:

[0016] The utility model belongs to the technical field of scooters, and particularly refers to a rear-wheel shock absorption mechanism of a scooter. The driver can fixedly connect the rear-wheel shock absorption mechanism to the rear end of the pedal of the scooter through a connecting seat, so that the scooter can be used normally. The swing arm includes a left swing arm plate and a right swing arm plate. The left swing arm plate and the right swing arm plate are rotatably arranged on the connecting seat, and the rear wheel is rotatably arranged between the left swing arm plate and the right swing arm plate. The installation method of the rear wheel is the same as the installation structure of the rear wheels on most scooters on the market at present. A rotating shaft passes through the left swing arm plate, the rear wheel and the right swing arm plate, enabling the rear wheel to rotate smoothly. A shock absorber is rotatably arranged at the installation part at the bottom of the connecting seat. The shock absorber is a common shock absorber on the market, mainly applied to automobiles. It includes a shock absorber main shaft and a shock spring sleeved on the shock absorber main shaft. Since the shock absorber main shaft passes through the driving hole on the lower connecting plate of the shock absorber, and both ends of the shock spring are respectively abutted against the lower connecting plate of the shock absorber and the shock absorber upper retaining plate at the top of the shock absorber main shaft. When the driver passes through a bumpy road section, at this time, the rear wheel will drive the left swing arm plate and the right swing arm plate to rotate upward relative to the connecting seat. At this time, the left swing arm plate and the right swing arm plate will drive the lower connecting plate of the shock absorber to rotate upward around the rotation connection points of the left swing arm plate, the right swing arm plate and the connecting seat. Since the bottom end of the shock absorber main shaft is rotatably connected to the installation part, when the lower connecting plate of the shock absorber rotates upward, it will move horizontally to the right. At this time, the lower connecting plate of the shock absorber will drive the shock absorber main shaft to rotate outward around the rotation point with the installation part through the driving hole. The shock spring on the shock absorber main shaft will also rotate outward together with the shock absorber main shaft, so that the bottom end of the shock spring can always be abutted against the lower connecting plate of the shock absorber, and at the same time, the left swing arm plate, the lower connecting plate of the shock absorber and the right swing arm plate can rotate smoothly. Since both ends of the shock spring are respectively abutted against the lower connecting plate of the shock absorber and the shock absorber upper retaining plate, when the lower connecting plate of the shock absorber rotates upward, it can compress the shock spring to achieve the shock absorption effect. Compared with most scooters on the market at present, only the front-wheel shock absorption mechanism is available, and most rear wheels of scooters do not have a shock absorption mechanism. When the driver rides a scooter on a bumpy road section, since the front-wheel shock absorption mechanism cannot completely eliminate the vibration, at this time, the bumpy feeling will be transmitted to the feet through the rear wheel and the pedal, generating vibration fatigue on the ankles, greatly reducing the driving comfort of the driver, and even accumulating to form mild damage to the ankles in the long run. The utility model can install the rear-wheel shock absorption mechanism to the rear end of the pedal, so that when the driver rides a scooter, the shock absorption effect can also be achieved through the mutual cooperation of the shock absorber and the lower connecting plate of the shock absorber, making the driver more comfortable when riding, having a better driving experience, and being able to greatly reduce the strong vibration received by the feet, avoiding the occurrence of vibration fatigue of the ankles, and effectively protecting the ankles.

[0037] The present utility model will be further described below in conjunction with specific embodiments:

[0038] The utility model belongs to the technical field of scooters, and particularly refers to a rear-wheel shock-absorbing mechanism of a scooter. The driver can fixedly connect the rear-wheel shock-absorbing mechanism to the rear end of the pedal 1 of the scooter through the connecting seat 2, so that the scooter can be used normally. The swing arm 3 includes a left swing arm plate 5 and a right swing arm plate 6. The left swing arm plate 5 and the right swing arm plate 6 are rotatably arranged on the connecting seat 2, and the rear wheel 4 is rotatably arranged between the left swing arm plate 5 and the right swing arm plate 6. The installation method of the rear wheel 4 is the same as the installation structure of the rear wheels on most scooters on the market at present. A rotating shaft passes through the left swing arm plate 5, the rear wheel 4 and the right swing arm plate 6, enabling the rear wheel 4 to rotate smoothly. The installation part 7 at the bottom of the connecting seat 2 is rotatably provided with a shock absorber 8. The shock absorber 8 is a common shock absorber on the market, mainly used in automobiles. It includes a shock absorber main shaft 11 and a shock absorber spring 12 sleeved on the shock absorber main shaft 11. Since the shock absorber main shaft 11 passes through the driving hole 10 on the shock absorber lower connecting plate 9, and the two ends of the shock absorber spring 12 are respectively abutted against the shock absorber lower connecting plate 9 and the shock absorber upper retaining piece 13 at the top of the shock absorber main shaft 11. When the driver passes through a bumpy road section, at this time, the rear wheel 4 will drive the left swing arm plate 5 and the right swing arm plate 6 to rotate upward relative to the connecting seat 2. At this time, the left swing arm plate 5 and the right swing arm plate 6 will drive the shock absorber lower connecting plate 9 to rotate upward around the rotation connection points of the left swing arm plate 5, the right swing arm plate 6 and the connecting seat 2. Since the bottom end of the shock absorber main shaft 11 is rotatably connected to the installation part 7, when the shock absorber lower connecting plate 9 rotates upward, it will move horizontally to the right. At this time, the shock absorber lower connecting plate 9 will drive the shock absorber main shaft 11 to rotate outward around the rotation point with the installation part 7 through the driving hole 10. The shock absorber spring 12 on the shock absorber main shaft 11 will also rotate outward together with the shock absorber main shaft 11, so that the bottom end of the shock absorber spring 12 can always be abutted against the shock absorber lower connecting plate 9, and at the same time, the left swing arm plate 5, the shock absorber lower connecting plate 9 and the right swing arm plate 6 can rotate smoothly. Since the two ends of the shock absorber spring 12 are respectively abutted against the shock absorber lower connecting plate 9 and the shock absorber upper retaining piece 13, when the shock absorber lower connecting plate 9 rotates upward, it can compress the shock absorber spring 12 to achieve the shock-absorbing effect. Compared with most scooters on the market at present, only the front-wheel shock-absorbing mechanism is available, and most of the rear wheels of scooters do not have a shock-absorbing mechanism. When the driver rides the scooter on a bumpy road section, since the front-wheel shock-absorbing mechanism cannot completely eliminate the vibration, at this time, the bumpy feeling will be transmitted to the feet through the rear wheel and the pedal 1, generating vibration fatigue on the ankles, greatly reducing the driving comfort of the driver, and even accumulating to form a mild injury to the ankles in the long run. The utility model can install the rear-wheel shock-absorbing mechanism to the rear end of the pedal 1, so that when the driver rides the scooter, the shock-absorbing effect can also be achieved through the mutual cooperation of the shock absorber 8 and the shock absorber lower connecting plate 9, making the driver more comfortable when riding, having a better driving experience, and being able to greatly reduce the severe vibration received by the feet, avoiding the occurrence of vibration fatigue of the ankles.It can effectively protect the ankle.

The mounting portion 7 is arranged at the bottom of the mounting member 15. The mounting portion 7 includes a left frame plate 16 and a right frame plate 17. A rotating block 18 is provided at the bottom end of the shock absorber main shaft 11. The rotating block 18 is arranged below the shock absorber lower connecting plate 9. The rotating block 18 is arranged between the left frame plate 16 and the right frame plate 17 and is rotatably connected to the left frame plate 16 and the right frame plate 17. The shock absorber main shaft 11 is rotatably connected to the left frame plate 16 and the right frame plate 17 through the rotating block 18 at the bottom end, and the rotating block 18 is located between the left frame plate 16 and the right frame plate 17, which can limit the random left and right movement of the rotating block 18. When the shock absorber lower connecting plate 9 rotates upward, the shock absorber main shaft 11 can smoothly rotate outward through the rotating block 18.

[0040] Preferably, a left limiting plate 19 and a right limiting plate 20 are provided at the rear side of the connecting block 14. The mounting member 15 is arranged between the left limiting plate 19 and the right limiting plate 20. Through holes 21 are formed on both sides of the mounting member 15. Hinge holes 22 are formed on both the left limiting plate 19 and the right limiting plate 20. The left swing arm plate 5 and the right swing arm plate 6 are respectively arranged on one side of the left limiting plate 19 and the right limiting plate 20. Through holes 23 are formed on both the left swing arm plate 5 and the right swing arm plate 6. A rotating shaft 24 passing through the through hole 23, the hinge hole 22 and the through hole 21 is provided on the connecting block 14. Since hinge holes 22 are provided on both the left limiting plate 19 and the right limiting plate 20 at the rear side of the connecting block 14, and the mounting member 15 is located between the left limiting plate 19 and the right limiting plate 20, and through holes 21 are formed on both sides of the mounting member 15, and the left swing arm plate 5 and the right swing arm plate 6 are respectively located on one side of the left limiting plate 19 and the right limiting plate 20, the through hole 21, the hinge hole 22 and the through hole 23 can be aligned with each other. Thus, only one rotating shaft 24 passing through the through hole 21, the hinge hole 22 and the through hole 23 can rotatably connect the left swing arm plate 5 with the left limiting plate 19 and the right swing arm plate 6 with the right limiting plate 20, and the mounting member 15 can be smoothly mounted at the rear side of the connecting block 14, making the structure of the rear wheel shock absorption mechanism simpler, effectively reducing the manufacturing cost, and being more convenient and labor-saving for workers during assembly.

[0041] Preferably, a rotation hole 25 is formed in the rotation block 18, and mounting holes 26 are formed in both the left frame plate 16 and the right frame plate 17. A rotation rod 27 is arranged in the rotation hole 25 and the mounting holes 26; the rotation block 18 is rotationally mounted between the left frame plate 16 and the right frame plate 17 by the rotation rod 27 passing through the rotation hole 25 in the rotation block 18 and the mounting holes 26 in the left frame plate 16 and the right frame plate 17.

[0042] Preferably, a connection hole 28 is formed in the connection block 14, and a fixing hole 29 is formed in the mounting member 15. A fixing rod 30 is arranged in the connection hole 28 and the fixing hole 29; the mounting member 15 is fixedly connected to the connection block 14 through the connection hole 28 and the fixing rod 30 in the connection hole 28. The number of the connection holes 28, the fixing holes 29, and the fixing rods 30 is six, which can make the connection between the connection block 14 and the mounting member 15 more stable and firm, thereby avoiding the loosening between the connection block 14 and the mounting member 15 and the separation of the mounting member 15 from the connection block 14 after the driver drives the scooter for a long time, and ensuring the driving safety of the driver.

[0043] Preferably, mounting plates 31 are symmetrically formed at the top of the mounting member 15. The mounting plates 31 are inclined towards the rear wheel 4 at the top of the mounting member 15. A mudguard 32 is arranged on the symmetric mounting plates 31; the arrangement of the mudguard 32 can prevent the rear wheel 4 from rolling up the accumulated water when the driver drives the scooter through a road surface with accumulated water, so as to avoid wetting the driver's trouser legs with the accumulated water and causing unnecessary trouble. When riding, the rider can also place the heel of the rear foot on the upper surface of the mudguard 32, making the rider more comfortable and stable when riding.

[0044] Preferably, mounting grooves 33 are provided on the mounting plates 31. An installation block 34 is provided between the symmetric mounting plates 31. Fixing parts 35 are provided at both ends of the installation block 34. The fixing parts 35 at both ends of the installation block 34 are respectively arranged in the mounting grooves 33 of the symmetric mounting plates 31 and fixedly connected to the mounting plates 31. A mounting threaded hole 36 is provided on the mounting block 34, and a fixing threaded hole 37 is provided on the fender 32. A threaded rod 38 is provided in the mounting threaded hole 36 and the fixing threaded hole 37; the installation block 34 is fixedly connected to the mounting plate 31 through the fixing part 35 arranged in the mounting groove 33 of the mounting plate 31, so that the two mounting plates 31 are connected together, making the whole mounting part 15 more firm. Moreover, the fender 32 is fixedly connected to the mounting block 34 through the threaded rod 38 in the mounting threaded hole 36 and the fixing threaded hole 37. Since dirt is likely to accumulate on the fender 32 after the scooter is used for a long time, the driver can separate the fender 32 from the mounting block 34 by rotating the threaded rod 38 at this time, thus facilitating the cleaning of the fender 32 and the shock absorption mechanism.

[0045] Preferably, positioning holes 39 are provided at both ends of the lower connecting plate 9 of the shock absorber. Linking holes 40 are formed on both the left swing arm plate 5 and the right swing arm plate 6. A linking rod 41 is provided in the positioning hole 39 and the linking hole 40; the lower connecting plate 9 of the shock absorber is installed between the left swing arm plate 5 and the right swing arm plate 6 and fixedly connected to the left swing arm plate 5 and the right swing arm plate 6 through the linking rod 41 in the positioning hole 39 at one end and the linking rod 41 in the connecting hole 28 of the left swing arm plate 5 and the linking rod 41 in the connecting hole 28 of the right swing arm plate 6 at the other end. When the driver passes through a bumpy road section, after the rear wheel 4 drives the left swing arm plate 5 and the right swing arm plate 6 to rotate upward, at this time, the left swing arm plate 5 and the right swing arm plate 6 can smoothly drive the lower connecting plate 9 of the shock absorber to rotate upward, so that the shock absorption spring 12 is compressed, and the scooter achieves the shock absorption effect.

[0046] Preferably, connecting plates 42 are provided at both ends of the front side of the connecting block 14. Plate holes 43 are formed in the connecting plates 42; when installing the rear wheel shock absorption mechanism to the rear end of the pedal 1, the driver places the rear end of the pedal 1 between the connecting plates 42 at both ends of the connecting block 14. At this time, after the user aligns the holes on both sides of the pedal 1 with the plate holes 43 on the two connecting plates 42, then screws are inserted into the plate holes 43 and the holes on both sides of the pedal 1, so that the pedal 1 is fixedly connected to the connecting block 14 together.

[0047] Preferably, the driving hole 10 is an oval hole; when the manufacturer assembles the rear-wheel shock-absorbing mechanism, if the bottom end surface of the shock spring 12 on the shock absorber main shaft 11 cannot fully contact the lower shock absorber connecting plate 9, at this time, the assembly worker can pull the shock absorber main shaft 11 to move along the driving hole 10 on the lower shock absorber connecting plate 9, so that the bottom end surface of the shock spring 12 can fully contact the lower shock absorber connecting plate 9. Thus, when the lower shock absorber connecting plate 9 moves upward, it can evenly apply an upward pressure to the shock spring 12, avoiding uneven stress on the shock spring 12 and thus preventing the situation where the shock absorption effect of the scooter is affected.

[0048] The above embodiments are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
