[0002] The seat height of existing shared bicycles is fixed, and it is difficult to meet the needs of users of different heights and shapes, especially when taller users sit on lower seats and ride.
In order to overcome this technical problem, the seats of some shared bicycles are also designed to be liftable and locked and positioned by cam locks. However, users need to manually adjust the seats when using shared bicycles, which is not convenient enough.

Embodiment 1
[0032] combine Figure 1 to Figure 4 As shown, the present embodiment is a shared bicycle, including a frame 2, a head tube 22 positioned above the front of the frame for controlling the direction of the front wheels, and a seat 4 mounted on the upper end of the middle of the frame.
[0033] A cylinder for adjusting the height of the seat is connected between the seat and the vehicle frame, the cylinder is connected with an air pump through a pipeline, and the pipeline between the air pump and the cylinder is connected with a solenoid valve for controlling the filling and deflation of the cylinder; The solenoid valve is a three-way two-position solenoid valve.
[0034] The air pump, electromagnetic valve and controller can be installed under the seat or in the metal pipe forming the vehicle frame, or a container for installing the above-mentioned components can be added independently on the vehicle frame.
[0035] When the three-way two-position solenoid valve is not energize...
Embodiment 2
[0058] combine Figure 5 to Figure 8 As shown, this embodiment makes further detailed improvements on the basis of embodiment 1:
[0059] The air pump includes a pump body 11, and an air inlet valve 121 and an air outlet valve 122 respectively connected to the pump body. Both the air inlet valve 121 and the air outlet valve 122 are one-way valves.
[0060] The pump body includes a base 111 and a pump body part 112 integrally connected to the upper end of the base.
[0061] A three-way ventilation pipe 1113 is formed on the base, and the inlet valve and the outlet valve are respectively connected to two ports of the ventilation pipe on the base, and the other port of the ventilation pipe communicates with the pump body.
[0062] The pump body part includes a bellows part 1121 that can expand and contract in the axial direction. The axial section of the bellows part is wavy. 1122.
[0063] The first coils 112 a and the second coils 112 b are arranged alternately in each of th...

Abstract
The invention discloses a shared bicycle which comprises a frame, a head tube located above the front part of the frame and used for controlling the direction of a front wheel, and a seat mounted at the upper end of the middle part of the frame, wherein a cylinder for adjusting the height of the seat is connected between the seat and the frame; the cylinder is connected with an air pump through a pipeline; the pipeline between the air pump and the cylinder is connected with an electromagnetic valve for controlling the cylinder to be inflated and deflated; the electromagnetic valve is a three-way two-position electromagnetic valve; a fingerprint password input unit for identifying user identity information is mounted at the lower end of the rear part of the seat; the fingerprint password input unit, the air pump and the electromagnetic valve are all electrically connected with a controller. According to the shared bicycle, when the shared bicycle is used for the first time, the seat is adjusted to a riding comfortable height through a seat adjustment button; in the subsequent use process, after the shared bicycle identifies the corresponding user identity information, the height of the seat is automatically adjusted to a height state set at the last time; therefore, a user can feel comfortable when riding the shared bicycle, and the user experience is improved.
Description
technical field [0001] The invention belongs to the field of public transportation tools, in particular to the field of shared bicycles. Background technique [0002] The seat height of existing shared bicycles is fixed, which is difficult to meet the needs of users of different heights and shapes, especially when taller users sit on lower seats and ride. In order to overcome this technical problem, the seats of some shared bicycles are also designed to be liftable and locked and positioned by cam locks. However, users need to manually adjust the seats when using shared bicycles, which is not convenient enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shared bicycle whose seat can automatically adjust the height according to different users in view of the deficiencies in the prior art. [0004] In order to achieve the purpose of the present invention, the following technical solutions are adopted: a sha...
