Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a scooter and its frame. Background Technology

[0002] Scooters are handheld personal commuting tools and sporting goods powered by human or electricity. They can be divided into electric scooters and human-powered scooters. Electric scooters are equipped with electric motors and are powered by electricity; human-powered scooters are powered by the rider pushing off the ground with their feet. Scooters are usually made of either aluminum alloy or steel. Aluminum alloy scooters are lightweight and corrosion-resistant, making them suitable for everyday use, while steel scooters are more robust but relatively heavier.

[0003] After prolonged use, the control unit and energy storage unit of a scooter will generate high temperatures, requiring timely heat dissipation to prevent malfunctions. However, in the current scooter structure, the control unit and energy storage unit are placed in the same frame mounting cavity, causing the heat generated by both to accumulate and create a high-temperature environment. This not only leads to a decrease in the performance of the control unit and a slower response, but also affects the charging and discharging efficiency and lifespan of the energy storage unit, thus significantly reducing the scooter's range and making it difficult to meet the daily travel needs of users. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a scooter and frame, aiming to improve the problem in the prior art where the scooter's structural control unit and energy storage unit are placed in the same frame mounting cavity, and the heat generated by the two during operation will be superimposed, forming a high temperature environment, which greatly reduces the scooter's range and makes it difficult to meet the user's daily travel needs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a scooter and frame, comprising a frame, a main beam fixedly connected to the left side of the frame, a pole base rotatably connected to the inner wall of the main beam, a threaded rod fixedly connected to the top of the pole base, a pole head rotatably connected to the outer wall of the threaded rod, a locking sleeve provided on the outer wall of the pole head, a screw threadedly connected to the inner wall of the locking sleeve, a rotating shaft rotatably connected to the front end of the screw, a rotating handle fixedly connected to the outer wall of the rotating shaft, multiple rear diffusers fixedly connected to the right side of the frame, multiple front diffusers fixedly connected to the left side of the frame, a control unit fixedly connected between adjacent front and rear diffusers, a battery storage device fixedly connected to the middle of the inner wall of the frame, and a shock-absorbing mechanism fixedly connected to the right side of the frame, the shock-absorbing mechanism being used to dampen vibrations in the structure.

[0006] As a further description of the above technical solution:

[0007] The damping mechanism includes a support frame, the left side of which is fixedly connected to the right side of the vehicle frame. A shock absorber is rotatably connected to the right side of the inner wall of the support frame, and a positioning frame is rotatably connected to the right end of the shock absorber. A rear rocker arm is fixedly connected to the bottom of the positioning frame, and a support shaft is rotatably connected to the left side of the inner wall of the rear rocker arm. The outer wall of the support shaft is rotatably connected to the bottom of the vehicle frame near the edge.

[0008] As a further description of the above technical solution:

[0009] The inner walls of the rear rocker arm are rotatably connected to adjacent drive wheels, and a mudguard is fixedly connected to the top right side of the rear rocker arm.

[0010] As a further description of the above technical solution:

[0011] A bracket is fixedly connected to the bottom front side of the frame, and a foot support is rotatably connected to the bottom of the bracket.

[0012] As a further description of the above technical solution:

[0013] A front rocker arm is rotatably connected to the bottom end of the frame base, and a rear foot pedal is fixedly connected to the top right side of the frame.

[0014] As a further description of the above technical solution:

[0015] A mudguard is fixedly connected to the top of the front rocker arm, and steering wheels are rotatably connected between adjacent inner walls of the front rocker arm.

[0016] As a further description of the above technical solution:

[0017] The top of the handlebar head is fixedly connected to the stem, the top of the stem is fixedly connected to the instrument, and the upper middle part of the outer wall of the handlebar head is fixedly connected to the light.

[0018] As a further description of the above technical solution:

[0019] A mudguard is fixedly connected to the top of the stem, and handlebars are fixedly connected to both the front and rear ends of the stem.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the optimized design of the frame brings a series of significant advantages. First, the meticulous design of the frame effectively increases the space of the mounting cavity, providing more ample space for the energy storage components. With the expansion of the mounting cavity, the capacity of the energy storage components is significantly improved, and the increase in energy storage capacity directly translates into enhanced product range, allowing for a longer-lasting user experience. At the same time, the control unit is placed in the heat dissipation cavities on both sides of the mounting cavity. To ensure the stable performance of the control unit during operation, deflectors are specially added to the design. These deflectors guide external airflow into the heat dissipation cavity, forming an efficient heat dissipation cycle. In this way, the heat generated by the control unit during operation can be carried away in time, effectively avoiding performance fluctuations caused by high temperatures, thereby ensuring the performance stability of the entire product during long-term operation.

[0022] 2. In this utility model, by rotating the rotating handle, the screw can be driven to rotate on the inner wall of the locking sleeve through the rotating shaft, thereby folding the left and right sides of the locking sleeve inward, thus positioning the position of the handlebar head and the threaded rod. Twisting in the opposite direction will loosen the locking sleeve and remove it downward. Then, the handlebar head is rotated along the threaded rod to fold it, thus achieving the purpose of folding the scooter inward. At the same time, the deflector can guide the external airflow to dissipate heat from the controller, improving practicality and portability.

[0023] 3. In this utility model, when the drive wheel encounters a bumpy road surface while driving, it will squeeze and pull the rear rocker arm to make it rotate along the support shaft at a small angle. Then, it will squeeze the positioning frame to squeeze the shock absorber synchronously, forcing it to rotate between the positioning frame and the support frame while undergoing elastic deformation, thereby buffering the vibration and improving comfort and practicality.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see the appendix Figure 5 - Appendix Figure 7 This utility model provides an embodiment of a scooter and its frame, including a frame 1. A main beam 22 is fixedly connected to the left side of the frame 1. A pole base 8 is rotatably connected to the inner wall of the main beam 22. A threaded rod 9 is fixedly connected to the top of the pole base 8. A pole head 3 is rotatably connected to the outer wall of the threaded rod 9. A locking sleeve 6 is provided on the outer wall of the pole head 3. A screw 7 is threadedly connected to the inner wall of the locking sleeve 6. A rotating shaft 4 is rotatably connected to the front end of the screw 7. A rotating handle 5 is fixedly connected to the outer wall of the rotating shaft 4. Multiple rear deflectors 23 are fixedly connected to the right side of the frame 1. Multiple front deflectors 24 are fixedly connected to the left side of the frame 1. A control unit 25 is fixedly connected between adjacent front deflectors 24 and rear deflectors 23. A power storage device 26 is fixedly connected to the middle of the inner wall of the frame 1. A shock-absorbing mechanism 2 is fixedly connected to the right side of the frame 1. The shock-absorbing mechanism 2 is used to dampen the structure.

[0035] Specifically, the main beam 22 has a specific frame shape and is hollow inside, providing installation space for the pole stand base 8. The locking sleeve 6 is cylindrical and fits tightly onto the outer wall of the pole stand head 3, allowing it to slide up and down on the pole stand head 3. The threads of the screw 7 match the threads on the inner wall of the locking sleeve 6. By rotating the screw 7, it can move back and forth within the locking sleeve 6. The rotating handle 5 is the part used by the rider to operate the movement of the screw 7. When the rider needs to lock the rotation angle of the pole stand head 3, they simply rotate the rotating handle 5 to push the screw 7 into the locking sleeve 6, thus locking the locking sleeve 6. The front and rear sides of the wall are clamped together, and the control unit 25 is placed in the profile cavities on both sides of the mounting cavity of the frame 1 without occupying the internal space of the mounting cavity, so that a larger battery can be installed, increasing the range and enabling it to travel a longer distance. The controller is placed on both sides of the mounting cavity of the frame 1. The design of the front deflector 24 introduces ambient air into the air intake, which helps to reduce the temperature of the controller during driving and reduces the failure rate of the controller. The energy storage component 26 is used to store electricity for the entire scooter function. The front deflector 24 and the rear deflector 23 can guide air to cool the control unit 25.

[0036] Please see the appendix Figure 2 - Appendix Figure 4 The damping mechanism 2 includes a support frame 201. The left side of the support frame 201 is fixedly connected to the right side of the frame 1. A shock absorber 202 is rotatably connected to the right side of the inner wall of the support frame 201. A positioning frame 203 is rotatably connected to the right end of the shock absorber 202. A rear rocker arm 204 is fixedly connected to the bottom of the positioning frame 203. A support shaft 205 is rotatably connected to the left side of the inner wall of the rear rocker arm 204. The outer wall of the support shaft 205 is rotatably connected to the bottom of the frame 1 near the edge.

[0037] Specifically, the rear swingarm 204 will rotate around the support shaft 205 at a certain angle under the action of the shock absorber 202 and the positioning frame 203, thereby converting the impact force of the road surface into the rotational motion of the rear swingarm 204, reducing the vibration transmitted to the frame 1 and the rider. The elastic force of the shock absorber 202 can be accurately transmitted to the positioning frame 203, thereby driving the rear swingarm 204 to perform corresponding movements.

[0038] Please see the appendix Figure 1 - Appendix Figure 3 The bottom of the base 8 is rotatably connected to the front rocker arm 11, the top right side of the frame 1 is fixedly connected to the rear foot pedal 16, the top of the front rocker arm 11 is fixedly connected to the mudguard 13, the inner wall of the front rocker arm 11 is rotatably connected to adjacent steering wheels 12, the bottom front side of the frame 1 is fixedly connected to the bracket 15, and the bottom of the bracket 15 is rotatably connected to the foot support 10.

[0039] Specifically, when encountering water accumulation and muddy roads, the steering wheel 12 will splash a lot of water and mud. The function of the mudguard 13 is to block this water and mud, preventing them from splashing onto the rider or other parts of the scooter, keeping the rider clean and the scooter tidy. At the same time, the mudguard 13 can also reduce air resistance to a certain extent and improve the scooter's riding efficiency.

[0040] Please see the appendix Figure 3 - Appendix Figure 5 The top of the handlebar head 3 is fixedly connected to the stem 20, the top of the stem 20 is fixedly connected to the instrument 19, the inner wall of the rear swingarm 204 is rotatably connected to adjacent drive wheels 17, the top right side of the rear swingarm 204 is fixedly connected to the mudguard 18, the top of the stem 20 is fixedly connected to the mudguard 18, the front and rear ends of the stem 20 are fixedly connected to the handlebars 14, and the upper middle part of the outer wall of the handlebar head 3 is fixedly connected to the light 21.

[0041] Specifically, the instrument panel 19 is used to control and display the vehicle's status, the texture on the outer wall of the handlebars 14 can increase the friction between the palm and the handlebars 14 to prevent the rider's hands from slipping when operating the scooter, and the mudguard 18 can block mud and water splashed up by the rotation of the drive wheel 17.

[0042] Working principle: The pole head 3 is rotatably connected to the threaded rod 9 and can rotate around the threaded rod 9 at a certain angle, thereby driving the front rocker arm 11 to rotate together, and synchronously driving the steering wheel 12 to turn. When the rotating handle 5 is rotated to push the screw 7 into the locking sleeve 6, the front and rear sides of the inner wall of the locking sleeve 6 are clamped inward, locking the relative position of the pole head 3 and the threaded rod 9 through friction. Then, the rotating handle 5 is rotated to the left to lock it through its own cam structure, thereby preventing the pole head 3 and the threaded rod 9 from rotating again. When the screw 7 is retracted, the locking sleeve 6 is released and the locking sleeve 6 is moved downward, allowing the pole head 3 to rotate around the threaded rod 9 again. It is then folded to the right, allowing the control unit 25 to be independently placed in the heat dissipation cavities on both sides of the frame, freeing it from the limitation of sharing the mounting cavity with the energy storage component 26. By using the front deflector 24 and rear deflector 23 to guide ambient air into the air intake, and utilizing the airflow during vehicle movement for air cooling, the operating temperature of the control unit 25 is specifically reduced. Lowering the temperature directly reduces malfunctions caused by high temperatures, resulting in a lower failure rate. A stable operating environment also allows for optimal performance. With the control unit 25 independently installed, the original mounting cavity space is no longer encroached upon, allowing for the inclusion of a larger energy storage component 26. This effectively increases the device's range and eliminates the space constraints between the control unit 25 and the energy storage component 26 within the same mounting cavity. Both can be fitted with larger components as needed. This avoids the superposition of heat generated during operation, reducing the adverse effects of high temperatures on each other's performance and lifespan.

[0043] When the rear wheel of the scooter encounters a bump, the vibration is transmitted to the entire mechanism through the rear rocker arm 204. The rear rocker arm 204 will rotate around the support shaft 205 at a certain angle, which will push the positioning frame 203 to cause the shock absorber 202 to undergo telescopic deformation. The shock absorber 202 absorbs the vibration energy through its own elastic characteristics and converts it into elastic potential energy, thereby reducing the vibration amplitude transmitted to the frame 1 and the rider, and achieving the shock absorption effect.

[0044] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
