Description

Technical Field

[0001] This utility model belongs to the field of backpack technology, specifically relating to electric cycling backpacks. Background Technology

[0002] Traditional backpacks can only be carried on the back. Some backpacks have added wheels and handles to the traditional backpack design, allowing them to be dragged. Nevertheless, the function of backpacks remains relatively limited.

[0003] Electric suitcases that can automatically follow you have also appeared on the market. However, suitcases are different from backpacks. Although some electric suitcases are designed so that users can ride on them, there are significant safety hazards and the riding experience is not good.

[0004] Furthermore, the larger size of suitcases makes cycling easier. However, for smaller backpacks, more issues need to be addressed for cycling: such as the backpack being unsuitable or the inability to ride while seated. Utility Model Content

The controller 5 controls the two hub motors according to the received front and rear swing angles of the left and right control pedals 32 to achieve forward, backward, and turning, etc.

[0072] Embodiment 2

[0073] See Figure 5 , the difference between Embodiment 2 and Embodiment 1 lies in defining the storage positioning structure and the unfolding positioning structure.

[0074] In this embodiment, a storage positioning hole and an unfolding positioning hole are formed on the telescopic footrest assembly 3. A straight-line positioning component 6 is provided on the main riding bracket 1. The straight-line positioning component 6 includes a positioning rod 61 that can be inserted into the storage positioning hole and the unfolding positioning hole. An elastic member 62 acting on the positioning rod 61 is provided to move it towards the storage positioning hole and the unfolding positioning hole. The storage positioning hole and the unfolding positioning hole are distributed front and back and are located at the center in the width direction of the telescopic footrest assembly 3. The storage positioning hole and the unfolding positioning hole are not shown in the figure.

[0075] In this embodiment, the outer end of the positioning rod 61 is located on the left and right outer sides of the telescopic main bracket. The positioning rod 61 is in a middle shape. The positioning rod 61 includes an installation part at the outer end, a convex part in the middle, and a positioning part at the inner end. One end of the elastic member 62 abuts against the convex part, and the other end abuts against the main riding bracket 1. The straight-line positioning component 6 further includes an operating member 63 fixed on the installation part. The radial dimension of the operating member 63 is larger than that of the installation part.

[0076] In this embodiment, the elastic member 62 is a compression spring.

[0077] In this embodiment, the operating member 63 is located above the main riding bracket 1. Even if the compression spring fails, the positioning rod 61 will remain in the storage positioning hole or the unfolding positioning hole under the action of gravity.

[0078] In this embodiment, when it is necessary to switch the state of the telescopic footrest assembly 3, lift the operating member 63 to overcome the acting force of the elastic member 62, so that the operating member 63 moves out of the storage positioning hole and the unfolding positioning hole on the telescopic bracket 31, and then the telescopic footrest assembly 3 can be pushed and pulled.

[0079] In this embodiment, the positioning of the telescopic footrest assembly 3 during storage and folding can be achieved through the straight-line positioning component 6 and the storage positioning hole and the unfolding positioning hole formed on the telescopic footrest assembly 3. The straight-line positioning component 6 can be composed of only three parts: the positioning rod 61, the elastic member 62, and the operating member 63, with a simple and reliable structure. Using a positioning rather than a limiting structure requires lower requirements for the structure of the main riding bracket 1, and the installation between the telescopic footrest assembly 3 and the main riding bracket 1 is easier.

[0080] Embodiment Three

[0081] See Figures 6 to 10 , the difference between Embodiment Three and Embodiment One is that the storage limiting structure and the unfolding limiting structure are defined.

[0082] In this embodiment, a storage positioning structure and an unfolding positioning structure are further formed between the telescopic footrest assembly 3 and the main riding bracket 1. The storage positioning structure fixes the telescopic bracket 31 in the storage position, and the unfolding positioning structure fixes the telescopic bracket 31 in the unfolding position.

[0083] In this embodiment, the telescopic pedal assembly 3 is provided with a storage limiting groove 312 and an unfolding limiting groove 311, and the main riding support 1 is provided with a swing limiting assembly 7. The swing limiting assembly 7 includes a limiting member 73 that can enter and exit the storage limiting groove 312 and the unfolding limiting groove 311. The limiting member 73 is directly or indirectly acted with an elastic member 72 that tends to move towards the main riding support 1.

[0084] In this embodiment, spring seats 15 extend from both the left and right outer sides of the main riding support 1. The elastic element 72 is a compression spring and is installed in the spring seat 15. The swing limiting assembly 7 also includes a swing seat 71. The other end of the compression spring abuts against the swing seat 71. The limiting element 73 is rotatably installed on the swing seat 71. The limiting element 73 is cylindrical.

[0085] In this embodiment, an angle limiting part 17 is also extended on the main riding support 1, which prevents the swing seat 71 from moving toward the main riding support 1.

[0086] In this embodiment, a pin mounting part 16 is formed on the main support frame 1 of the bicycle. The pin mounting part 16 has a pin hole. The swing limiting component 7 includes a pin 74 and a cap screw 75 disposed in the pin hole. One end of the pin 74 has a cap with an outer diameter larger than the pin hole, and the other end is fitted with a cap screw 75.

[0087] In this embodiment, there are two sets of swing limiting components 7, located on the left and right sides of the main riding support 1.

[0088] In this embodiment, the roller groove 12 has closed portions at the front and rear ends, forming front and rear blocking portions, and roller mounting holes 14 are provided on the main riding bracket 1. During installation, the components of the telescopic pedal assembly 3, excluding the rollers, are first inserted into the guide groove 11 of the main riding bracket 1. After insertion, the rollers are mounted onto the telescopic bracket 31 of the telescopic pedal assembly 3 through the four roller mounting holes 14 on the left and right sides of the main riding bracket 1.

[0089] In other embodiments, the elastic element may also be a torsion spring.

[0090] In this embodiment, when the telescopic pedal assembly 3 is in the extended state, due to the presence of the rear blocking part of the main riding support 1, the telescopic pedal assembly 3 cannot be pulled further back. At the same time, due to the presence of the angle limiting part 17 on the main riding support 1, the swing seat 71 and the limiting member 73 thereon cannot rotate toward the main riding support 1. Figure 10(The left side is counterclockwise, and the right side is clockwise), thus maintaining the position of the telescopic pedal assembly 3 in the unfolded state. When it needs to be folded up, the swing seats 71 of the left and right telescopic pedal assemblies 3 need to be operated to rotate the swing seats 71 and their limiting members 73 away from the main riding support 1 (in the direction of the arrow in the figure). After both limiting members 73 have rotated around their respective pins 74 into place (moving out of the unfolding limiting groove 311), the folding pedal assembly can be pushed in. After the folding pedal assembly is pushed in, the two limiting members 73 will rotate back towards the main riding support 1 and enter the folding limiting groove 312 under the action of the elastic member 72 (compression spring). When it needs to be unfolded again, simply pull the folding pedal assembly directly over the force of the two elastic members 72 (compression spring). In the unfolded state (i.e., in riding mode), it is necessary to ensure that the folding pedal assembly does not move back and forth relative to the main riding support 1. Therefore, the rear stop prevents the folding pedal assembly from moving backward, and the swing limit component 7 and the main riding support 1 prevent the folding pedal assembly from moving forward. In the folded state, there is no such requirement; it is sufficient that the folding pedal assembly does not move freely relative to the main riding support 1.

[0091] 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.
