Electric scooters are lightweight and easy to store.

[0003] In the prior art, electric scooters include a scooter body and a seat rotatably connected to the scooter body. A folding assembly is provided between the seat and the scooter body. The folding assembly has a relatively complex structure, which makes it inconvenient for users to switch the seat between the use state and the storage state. Utility Model Content

[0004] This utility model provides an electric scooter that aims to solve the problem that the folding assembly between the seat and the scooter body of existing electric scooters has a relatively complex structure, which makes it inconvenient for users to switch the seat between the use state and the storage state.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides an electric scooter, comprising:

[0007] Scooter frame;

[0008] A seat mechanism, which is rotatably connected to the scooter body;

[0009] The engagement assembly includes a first engagement member disposed on the scooter body and a second engagement member disposed on the seat mechanism, a first engagement tooth is provided around the first engagement member, and a second engagement tooth is provided around the second engagement member for engaging with the first engagement tooth.

[0010] A locking member, said locking member being used to drive the first engaging member and the second engaging member to engage together; and...

[0011] An elastic reset member is used to drive the first engaging member to disengage from the second engaging member;

[0012] The engagement component includes an engagement state and a disengagement state. When the engagement component switches from the disengagement state to the engagement state, the locking member drives the first engagement member and the second engagement member to engage and lock each other, thereby locking the seat mechanism relative to the scooter body and compressing the elastic reset member. When the engagement component switches from the engagement state to the disengagement state, the locking member releases the lock on the first engagement member and the second engagement member in the engagement state. Under the reset action of the elastic reset member, the first engagement member and the second engagement member disengage and release the relative lock between the seat mechanism and the scooter body, allowing the seat mechanism to rotate relative to the scooter body.

[0013] Further embodiment: The seat mechanism includes two connecting arms on the left and right sides and a seating part located between the two connecting arms, wherein one of the connecting arms is provided with a set of the engagement components between it and the scooter body; or, both the left and right connecting arms are provided with a set of the engagement components between them and the scooter body.

[0014] A further embodiment: the two connecting arms are rotatably connected to the scooter body via a pivot, and the first and second engaging members are coaxially arranged with the pivot.

[0015] Based on the above technical solution: the first engagement member and the second engagement member are coaxially arranged with the rotating shaft so that when the two connecting arms rotate, they simultaneously drive the second engagement member to rotate.

[0016] Further embodiment: The locking component includes a knob and a nut respectively located on the two connecting arms, one of the connecting arms is provided with a guide groove, the nut is located in the guide groove and is threadedly connected to one end of the rotating shaft, and the knob is synchronously connected to the other end of the rotating shaft.

[0017] Based on the above technical solution: the nut is located in the guide groove and is threaded to one end of the rotating shaft. The knob is synchronously rotated and connected to the other end of the rotating shaft. When the knob rotates clockwise, the distance between the knob and the nut is shortened, causing the first biting member and the second biting member to move closer to each other, thereby making the first biting member and the second biting member bite and lock together.

[0018] When the knob is rotated counterclockwise, the distance between the knob and the nut increases, causing the first and second engaging parts to move away from each other. Under the reset action of the elastic reset part, the first and second engaging parts disengage, thereby releasing the locking of the first and second engaging parts in the engaging state.

[0019] By setting the knob and the nut, the switching between the first and second engaging parts in the engaging and disengaging states becomes more stable.

[0020] Further solution: One of the connecting arms has a mounting groove on its outer side, and the knob is located in the mounting groove.

[0021] Based on the above technical solution, the mounting groove makes the rotation of the knob more stable.

[0022] A further embodiment: each of the first engagement members is fixedly connected to the scooter body, and each of the second engagement members is fixedly connected to its corresponding connecting arm.

[0023] Based on the above technical solution: each of the first engagement members is fixedly connected to the scooter body, and each of the second engagement members is fixedly connected to its corresponding connecting arm, so that relative rotation can be achieved when the first engagement member and the second engagement member are in a disengaged state.

[0024] Further solution: Each of the second engagement members is provided with a clearance hole, and each of the elastic reset members passes through its corresponding clearance hole and its two ends abut against its corresponding first engagement member and connecting arm, respectively.

[0025] Based on the above technical solution, the clearance hole makes the installation of the elastic reset component more convenient.

[0026] Further embodiment: The scooter body includes a pedal assembly, a handlebar assembly located in front of the pedal assembly, a front wheel rotatably disposed in front of the pedal assembly, and a rear wheel rotatably disposed in rear of the pedal assembly. The seat mechanism is rotatably connected to the pedal assembly, and the seat mechanism includes a usage state and a storage state.

[0027] When the seat mechanism is switched from the use state to the storage state, the seat mechanism rotates downward and backward to the upper side of the rear wheel, and the locking member drives the first biting member and the second biting member to bite and lock each other, thus locking the seat mechanism in the storage state.

[0028] When the seat mechanism switches from the storage state to the use state, the seat mechanism rotates upward and forward to the upper side of the pedal assembly, and the locking member drives the first biting member and the second biting member to bite and lock each other, thus locking the seat mechanism in the use state.

[0029] Based on the above technical solution: when the seat mechanism is in the storage state, the seat mechanism is located on the upper side of the rear wheel, preventing the seat mechanism from occupying the space of the pedal assembly, thereby allowing the user to have good legroom when standing and riding, and the present invention occupies less space when stored.

[0030] When the seat mechanism is in use, it is located on the upper side of the pedal assembly, making the user more comfortable when riding in a seated position.

[0031] Further solution: An angle limiting component is provided between the first and second engaging members.

[0032] Based on the above technical solution: the angle limiting component restricts the rotation angle of the seat mechanism between the use state and the storage state, so that the user will not rotate it excessively during use.

[0033] Further embodiment: The angle limiting component includes a positioning block disposed on the first engaging member and an arc-shaped positioning groove surrounding the second engaging member, with each positioning block located within its corresponding positioning groove; when the seat mechanism is in the retracted state, each positioning block abuts against one side wall of its corresponding positioning groove; when the seat mechanism is in the use state, each positioning block abuts against the other side wall of its corresponding positioning groove.

[0034] Based on the above technical solution: each of the positioning blocks is located in the corresponding positioning groove, so that the rotation of the seat mechanism relative to the pedal assembly is limited by the stroke of the positioning groove, preventing the seat mechanism from rotating excessively.

[0035] The beneficial effects of this utility model are as follows:

[0036] This invention utilizes a first engaging member on the scooter frame and a second engaging member on the seat mechanism. A first engaging tooth surrounds the first engaging member, and a second engaging tooth surrounds the second engaging member for engaging with the first engaging tooth. The engagement of the first and second engaging teeth enhances the stability of the seat mechanism in both the use and stowed states. A locking member drives the first and second engaging members to engage, thereby locking the rotation angle of the seat mechanism relative to the scooter frame, further ensuring stability in both the use and stowed states. An elastic reset member allows the first and second engaging members to automatically disengage when the locking member releases its hold, enabling the user to switch between the use and stowed states by rotating the seat mechanism. These features facilitate user operation. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0047] like Figures 1 to 6 As shown, this embodiment provides an electric scooter, including:

[0048] Scooter body 1;

[0049] Seat mechanism 2, which is rotatably connected to the scooter body 1;

[0050] The biting component 3 includes a first biting member 31 disposed on the scooter body 1 and a second biting member 32 disposed on the seat mechanism 2. A first biting tooth 311 is provided around the first biting member 31, and a second biting tooth 321 for biting with the first biting tooth 311 is provided around the second biting member 32.

[0051] Locking member 5, said locking member 5 being used to drive the first engaging member 31 and the second engaging member 32 to engage together; and,

[0052] The elastic reset member 6 is used to drive the first biting member 31 and the second biting member 32 to disengage from each other.

[0053] The engagement component 3 includes an engagement state and a disengagement state. When the engagement component 3 switches from the disengagement state to the engagement state, the locking member 5 drives the first engagement member 31 and the second engagement member 32 to engage and lock each other, thereby locking the seat mechanism 2 relative to the scooter body 1 and compressing the elastic reset member 6. When the engagement component 3 switches from the engagement state to the disengagement state, the locking member 5 releases the lock on the first engagement member 31 and the second engagement member 32 in the engagement state. Under the reset action of the elastic reset member 6, the first engagement member 31 and the second engagement member 32 disengage and release the relative lock between the seat mechanism 2 and the scooter body 1, allowing the seat mechanism 2 to rotate relative to the scooter body 1.

[0054] like Figure 2 As shown, the seat mechanism 2 includes two connecting arms 21 on the left and right sides and a seating portion 22 located between the two connecting arms 21. The seating portion 22 is located on the side of the two connecting arms 21 near the seating portion 22 and is fixedly connected to the two connecting arms 21. One of the connecting arms 21 has a set of engaging components 3 between its side near the scooter body 1 and the scooter body 1; or, both the left and right connecting arms 21 have a set of engaging components 3 between their sides near the scooter body 1 and the scooter body 1. Specifically, as shown... Figure 3 As shown, in this embodiment, a set of engagement components 3 is provided between each of the two connecting arms 21 on the left and right sides and the scooter body 1. The two engagement components 3 make the seat mechanism 2 more stable when it is in use or in storage.

[0055] like Figures 3 to 5As shown, the two connecting arms 21 are rotatably connected to the scooter body 1 via a rotating shaft 4, and the first engaging member 31 and the second engaging member 32 are coaxially arranged with the rotating shaft 4, so that when the two connecting arms rotate, they simultaneously drive the second engaging member to rotate.

[0056] like Figures 3 to 5 As shown, when both the left and right connecting arms 211 are equipped with a set of engaging components 3 near the scooter body 1, the locking member 5 includes a knob 51 and a nut 52 located on each of the two connecting arms 21. One of the connecting arms 21 has a guide groove 211, and the nut 52 is located in the guide groove 211 and threadedly connected to one end of the rotating shaft 4. The knob 51 is synchronously connected to the other end of the rotating shaft 4. Specifically, the knob 51 has a hexagonal connecting groove 212, and one side of the rotating shaft 4 has a hexagonal protrusion that engages in the connecting groove 212. The knob 51 is marked with indications that clockwise rotation locks the two connecting arms 21 and counterclockwise rotation unlocks the two connecting arms 21. An anti-disengagement component can be added to the side of the rotating shaft 4 where the nut 52 is located to prevent the nut 52 from disengaging. The anti-disengagement component can be fixedly connected to the rotating shaft 4 by welding. The knob 51 and nut 52 enable the first biting member 31 and the second biting member 32 in the two sets of biting components 3 to engage or disengage simultaneously, which is convenient for user operation.

[0057] like Figure 4 As shown, in order to make the knob 51 rotate more smoothly, a mounting groove 214 is provided on the outer side of one of the connecting arms 21, and the knob 51 is located in the mounting groove 214.

[0058] like Figures 3 to 5 As shown, in order to make the engagement between the first engagement member 31 and the second engagement member 32 more stable, each of the first engagement members 31 is fixedly connected to the scooter body 1 by bolts, and each of the second engagement members 32 is fixedly connected to its corresponding connecting arm 21 by bolts.

[0059] like Figures 3 to 5 As shown, in order to better install the elastic reset member 6, each of the second engagement members 32 is provided with a clearance hole 322, and each of the elastic reset members 6 passes through its corresponding clearance hole 322 and its two ends abut against its corresponding first engagement member 31 and connecting arm 21 respectively. The elastic reset member 6 is a spring.

[0060] like Figures 1 to 2As shown, the scooter body 1 includes a pedal assembly 111, a handlebar assembly 112 located in front of the pedal assembly 111, a front wheel 113 rotatably disposed in front of the pedal assembly 111, and a rear wheel 114 rotatably disposed behind the pedal assembly 111. The seat mechanism 2 is rotatably connected to the pedal assembly 111, and the seat mechanism 2 includes a usage state and a storage state.

[0061] like Figure 1 As shown, when the seat mechanism 2 is switched from the use state to the storage state, the locking member 5 releases the locking of the first biting member 31 and the second biting member 32 in the biting state. Under the reset action of the elastic reset member 6, the first biting member 31 and the second biting member 32 disengage and release the relative lock between the seat mechanism 2 and the scooter body 1. The seat mechanism 2 is rotated downward and backward to the upper side of the rear wheel 114, and the locking member 5 drives the first biting member 31 and the second biting member 32 to bite and lock each other, so that the seat mechanism 2 is locked in the storage state.

[0062] like Figure 6 As shown, when the seat mechanism 2 switches from the storage state to the use state, the locking member 5 releases the locking of the first engaging member 31 and the second engaging member 32 in the engaging state. Under the reset action of the elastic reset member 6, the first engaging member 31 and the second engaging member 32 disengage and release the relative lock between the seat mechanism 2 and the scooter body 1. The seat mechanism 2 is rotated upward and forward to the upper side of the pedal assembly 111, and the locking member 5 drives the first engaging member 31 and the second engaging member 32 to engage and lock with each other, so that the seat mechanism 2 is locked in the use state.

[0063] Specifically, an arc-shaped groove 213 is provided between the seating part 22 and the two connecting arms 21. When the seat mechanism 2 is in the retracted state, the groove 213 is fitted onto the upper side of the mudguard of the rear wheel 114, and the seating part 22 is located above the rear side of the rear wheel 114. The groove 213 makes the seat mechanism 2 occupy less space in the retracted state.

[0064] like Figure 5As shown, to prevent the user from excessively rotating the seat mechanism 2 during use, an angle limiting component 7 is provided between the first engaging member 31 and the second engaging member 32. The angle limiting component 7 includes a positioning block 71 disposed on the first engaging member 31 and an arc-shaped positioning groove 72 surrounding the second engaging member 32. Each positioning block 71 is located within its corresponding positioning groove 72. Specifically, there are two positioning grooves 72 and two positioning blocks 71, each corresponding to the other. When the seat mechanism 2 is in the retracted state, each positioning block 71 abuts against one side wall of its corresponding positioning groove 72. When the seat mechanism 2 is in the use state, each positioning block 71 abuts against the other side wall of its corresponding positioning groove 72. The positioning grooves 72 and the positioning blocks 71 allow the seat mechanism 2 to accurately switch between the use state and the retracted state.

[0065] Working principle explanation:

[0066] In this embodiment, the locking member 5 locks the first engaging member 31 and the second engaging member 32, preventing the seat mechanism 2 from rotating relative to the pedal assembly 111, thus making the seat mechanism 2 more stable in both the storage and use states. In this embodiment, the elastic reset member 6 is provided so that when the locking member 5 releases the locking of the first engaging member 31 and the second engaging member 32 in the engaged state, they can automatically disengage under the reset action of the elastic reset member 6, allowing the user to switch between the use and storage states by rotating the seat mechanism 2. In this embodiment, the seat mechanism 2 folds upwards towards the rear wheel 114 for storage. This storage method does not occupy the space of the pedal assembly 111, providing the user with more legroom in the storage state. Furthermore, an arc-shaped groove 213 is provided between the seating part 22 and the two connecting arms 21. In the storage state, the groove 213 fits onto the upper side of the mudguard of the rear wheel 114, further reducing the size of the scooter and making storage more convenient.

[0067] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
