[0058] Example 1

[0059] See Figures 1 to 9 The electric standing cycling backpack of Embodiment 1 of this utility model includes:

[0060] Cycling device 01;

[0061] Backpack 02;

[0062] Among them, the backpack 02 is fixed to the riding device 01;

[0063] Among them, the riding device 01 includes a riding main frame 1, two omnidirectional wheels 2 and two sets of telescopic pedal assemblies 3 mounted on the riding main frame 1. The telescopic pedal assembly 3 moves left and right relative to the riding main frame 1 and switches between the riding position and the storage position. The telescopic pedal assembly 3 includes a telescopic bracket 31, a control pedal 32 and a wheel 33 with a hub motor. The telescopic pedal assembly 3 and the omnidirectional wheels 2 are distributed in front and behind.

[0064] The riding device 01 also includes a battery and a controller. The control pedal 32 swings back and forth relative to the telescopic bracket 31. The control pedal 32 is equipped with a sensor 34, which detects the back and forth swing angle of the control pedal 32. The controller controls the two hub motors according to the back and forth swing angle signal detected by the sensor 34.

[0065] In this embodiment, the telescopic foot pedal assembly 3 is typically in front, and the omnidirectional wheel 2 is in the back.

[0066] In this embodiment, the battery and controller are not shown in the diagram.

[0067] In this embodiment, the structure of the main cycling support 1 is only shown in a simple way, and it can be designed accordingly as needed.

[0068] In this embodiment, the riding device 01 includes a guide structure for the left and right telescopic pedal assemblies 3. The main riding support 1 is provided with left and right guide assemblies 4, and the telescopic pedal assembly 3 also includes left and right movable frames 35 that cooperate with the left and right guide assemblies 4. The left and right guide assemblies 4 are fixed to the main riding support 1.

[0069] In this embodiment, the left and right guide components 4 include a pair of parallel hollow guide posts, the left and right movable frames 35 include guide sleeves 351 fitted over the two guide posts, and the left and right guide components 4 include a pair of left and right movable frames 35 including guide rods 352 located in the guide posts. The left and right telescopic foot pedal components 3 are mounted on the same pair of hollow guide posts.

[0070] In this embodiment, the riding device 01 includes a riding positioning structure and a storage positioning structure for positioning the left and right telescopic pedal assemblies 3. The telescopic pedal assembly 3 also includes a positioning plate 36, on which riding positioning holes 361 and storage positioning holes 362 are provided. The riding main support 1 is provided with a positioning component 5. When the positioning component 5 is located in the riding positioning hole 361, the telescopic pedal assembly 3 is positioned in the riding position. When the positioning component 5 is located in the storage positioning hole 362, the telescopic pedal assembly 3 is positioned in the storage position.

[0071] In other embodiments, the positions of the positioning hole and the positioning element 51 can be interchanged. That is, the telescopic pedal assembly 3 also includes a positioning plate 36, on which a riding positioning part 511 and a storage positioning part 511 are formed. The riding main support 1 is provided with a positioning hole. When the riding positioning part 511 is located in the positioning hole, the telescopic pedal assembly 3 is positioned in the riding position. When the storage positioning part 511 is located in the storage positioning hole 362, the telescopic pedal assembly 3 is positioned in the storage position.

[0072] In this embodiment, the positioning component 5 is equipped with a positioning spring 6 that moves toward the riding positioning hole 361 or the receiving positioning hole 362. The positioning spring 6 is a compression spring, and there are at least two positioning springs 6 on the same positioning component 5.

[0073] In this embodiment, the electric standing cycling backpack also includes a positioning mounting bracket 7 fixed on the main cycling bracket 1 and an operation linkage component 8 installed on the positioning mounting bracket 7. The operation linkage component 8 includes a linkage component 81 that is linked with the positioning component 5, an operation elastic component 82 that acts on the linkage component 81, and an operation component 83 that is fixedly connected to the linkage component 81.

[0074] In this embodiment, the positioning component 5 moves vertically, and the linkage 81 moves horizontally. The positioning component 5 moves vertically and is located above the top plate. Even if the positioning spring component 6 fails, the positioning component 5 will remain in the riding positioning hole 361 or the storage positioning hole 362 under the action of gravity, thereby ensuring safety.

[0075] In other embodiments, the positioning component 5 can also move horizontally.

[0076] In this embodiment, the positioning component 5 has a force-bearing surface 521, and the linkage 81 includes an abutting surface 811 that abuts against the force-bearing surface 521 of the positioning component 5. At least one of the force-bearing surface 521 and the abutting surface 811 is an arc surface. Specifically, the abutting surface 811 is a plane, and the force-bearing surface 521 is a cylindrical surface.

[0077] In this embodiment, the positioning mounting bracket 7 guides the positioning component 5.

[0078] In this embodiment, the positioning and installation component guides the operation linkage component 8.

[0079] In this embodiment, an anti-detachment structure is formed between the positioning mounting bracket 7 and the operating member 83. The anti-detachment structure includes an anti-detachment screw 84 provided on the operating member 83 and an anti-detachment part on the positioning mounting bracket 7.

[0080] In this embodiment, the positioning mounting bracket 7 restricts the displacement of the operating member 83 toward the positioning component 5.

[0081] In this embodiment, the positioning component 5 includes a positioning member 51 and a force-receiving member 52. The positioning member 51 includes a positioning part 511, a connecting part 512, a spring mounting part 513, and an abutment mounting part 514. The force-receiving member 52 is rotatably connected to the abutment mounting part 514 via a pin 53. The force-receiving member 52 is rotatable, thereby reducing the friction between the force-receiving member 52 and the abutment member when they move together, ensuring smooth movement of both and preventing jamming.

[0082] In this embodiment, the electric standing cycling backpack also includes a cycling limiting structure and a storage limiting structure. The inner end of the positioning plate 36 is provided with a cycling limiting anti-detachment plate 37. When the cycling limiting anti-detachment plate 37 contacts the positioning mounting bracket 7, it forms a cycling limiting structure. When the telescopic bracket 31 contacts the left and right guide components 4, it forms a storage limiting structure. By setting the cycling limiting anti-detachment plate 37, the telescopic pedal assembly is prevented from detaching. Furthermore, when the cycling limiting anti-detachment plate abuts against the positioning mounting bracket 7, it indicates that the telescopic pedal assembly 3 has moved to the cycling position. When the telescopic bracket 31 contacts the end face of the left and right guide components 4 (hollow guide posts), it indicates that the telescopic pedal assembly 3 has moved to the storage position.

[0083] In this embodiment, sensor 34 is a gyroscope.

[0084] In this embodiment, the backpack 02 also includes a retractable handle.

[0085] The telescopic pedal assembly 3 of the electric standing cycling backpack in this embodiment extends and retracts as follows: In the retracted state, the positioning member 51 of the positioning assembly 5 is positioned in the storage positioning hole 362 of the positioning plate 36 of the telescopic pedal assembly 3 under the action of the positioning spring member 6, and the operating member 83 of the linkage operation assembly does not abut against the positioning member 51 under the action of the operating spring member 82; when riding is required, the operating member 83 is pressed backward, overcoming the operating spring member 82 to make the entire linkage operation assembly move backward, and the abutting surface 811 of the linkage member 81 abuts against the force-bearing surface 521 of the force-bearing member 52 of the positioning assembly 5, overcoming the positioning spring. The force of component 6 causes the force-bearing component 52 to rotate, and at the same time the entire positioning assembly 5 rises. The positioning part 511 of the positioning component 51 of the positioning assembly 5 rises and moves out of the storage positioning hole 362 of the positioning plate 36. At this time, the telescopic pedal assembly 3 can be moved left and right (after moving the telescopic pedal assembly 3, the operating component 83 no longer needs to be pressed. Under the action of the operating spring component 82, the operating component 83 does not abut against the force-bearing component 52 of the positioning assembly 5). When the telescopic pedal assembly 3 moves into place, the positioning component 51 enters the riding positioning hole 361 of the positioning plate 36 under the action of the positioning spring component 6, and enters the riding state.

[0086] The beneficial effects of the electric standing cycling backpack of Embodiment 1 of this utility model are as follows: It has a cycling device 01, which includes a main cycling frame 1, two omnidirectional wheels 2 mounted on the main cycling frame 1, two sets of telescopic pedal assemblies 3, a battery, and a controller. The telescopic pedal assembly 3 includes a telescopic bracket 31, a control pedal 32, and a sensor 34 for detecting the forward and backward swing angle of the control pedal 32. When riding is required, the telescopic pedal assembly 3 is unfolded to the left and right, and the user steps on the control pedal 32 (there are two on the left and right sides) to control the forward and backward swing angle of the left and right control pedals 32 (the control principle can be referred to as a two-wheeled electric balance vehicle). The controller controls the two hub motors according to the received forward and backward swing angle of the left and right control pedals 32 to realize forward, backward, and turning movements. It adopts a method similar to operating a two-wheeled electric balance vehicle instead of sitting and operating the electric suitcase with a handle (similar to a tricycle). It has two omnidirectional wheels 2, and the two omnidirectional wheels 2 and two wheels 33 are distributed in front and behind, making the riding more stable. By setting up a linkage operation component, the positioning component 5 can be operated more conveniently. The linkage operation component moves horizontally, and the positioning component 5 moves up and down, ensuring safety.

[0087] The above description is merely a specific embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
