[0014] Preferably, the discharge socket of the battery includes a 20V discharge socket and a 5V discharge socket.
[0015] Beneficial technical effects of the technical solution of the utility model:
[0016] (1) Compared with the excitation generator, the three-phase AC permanent magnet generator does not require additional electrical energy for excitation, which can save energy and thus improve the generator's power generation efficiency. In addition, the permanent magnet generator has good low-speed power generation performance and high output power. When running at low speed, it can reduce the manpower required to fully charge the battery during the power generation process.
[0017] The three-phase AC permanent magnet generator is installed on a bracket, and a handle for a user to hold, a saddle for a user to sit on, and a pedal structure are installed above the strip base. The handle, the pedal structure, and the saddle are arranged in the horizontal direction along the length direction of the bracket. The pedal structure is rotationally coordinated with the strip base, and the pedal structure is transmission-connected with the rotor of the three-phase AC permanent magnet generator. When the user applies force to the pedal structure, the three-phase AC permanent magnet generator can generate electricity. The AC power generated by the generator is rectified by a rectifier and then transmitted to a storage battery.
[0018] (2) The handle, the footrest structure, and the saddle are all installed above the strip-shaped base. The positions of the handle, the footrest structure, and the saddle in the horizontal direction are arranged along the length direction of the strip-shaped base, which can reduce the space occupied by the generator set in the width direction. Rotating rods are rotatably connected to both sides of the strip-shaped base, and the rotation axis of the rotating rods is the vertical axis. When the generator set needs to be used to generate electricity, the rotating rods are swung and unfolded. The rotating rods on both sides of the strip-shaped base can respectively prevent the whole generator set from tipping towards this side, enabling the generator set to be stably placed for users to use. When the generator set does not need to be used, only the rotating rods on both sides of the strip-shaped base need to be swung towards the strip-shaped base, so that the rotating rods are folded and attached to the side of the strip-shaped base, which can also reduce the space occupied by the generator set and facilitate storage and carrying.
[0019] (3) The handle includes a main body and two handle segments rotatably connected to the main body. One end of the handle segment is rotatably connected to the main body, and the other end approaches or moves away from the saddle during rotation. When the generator set does not need to be used, the two handle segments can also be controlled to rotate towards the saddle, so that the handle segments are folded, which is convenient for the handle to reduce the occupied space.
[0020] A limiting structure that prevents the handle segment from rotating away from the saddle is installed on the side of the main body facing away from the saddle. When the user sits on the saddle and uses the generator set to generate electricity, a part of the user's weight is transmitted to the handle segment through the hand, and using the limiting structure to prevent the handle segment from rotating away from the saddle can keep the position of the handle segment stable for the user to use.
[0021] (4) The seat adjustment rod and the handle adjustment rod are respectively inserted into the first sleeve and the second sleeve and are slidably matched with the corresponding sleeves. At the same time, the positions of the seat adjustment rod and the handle adjustment rod are locked by the first bolt and the second bolt. When the user uses the generator set, by controlling the seat adjustment rod and the handle adjustment rod to slide in the corresponding sleeves and using the corresponding bolts to re-lock, the height positions of the saddle and the handle can be adjusted, making the generator set suitable for different users. In addition, when adjusting the height positions of the saddle and the handle, the overall space occupied by the generator set can also be adjusted. Reducing the height positions of the saddle and the handle can conveniently reduce the overall space occupied by the generator set, which is convenient for moving or storing the generator set.
[0022] (5) A connection structure is provided between the strip-shaped base and the handle. The connection structure is rotatably connected to the base, and a third bolt for locking the rotation angle of the connection structure is also provided on the strip-shaped base. By adjusting the rotation angle of the connection structure, the horizontal distance between the handle and the saddle can be changed, making the generator set suitable for different users. Moreover, when the handle is rotated to be close to the saddle, the overall space occupied by the generator set can also be reduced, which is convenient for moving or storing the generator set.

[0030] The following will combine the attached Figures 1 to 4 and specific embodiments to elaborate in detail on the technical solutions of the human-powered pedal-driven mobile generator set of the present utility model.
[0031] Embodiment
[0032] AsFigures 1 to 4 As shown, a human-powered tread-type movable generator set of this embodiment includes a bracket 1 and a power generation device installed on the bracket 1. The bracket 1 includes a horizontal strip base 11 and support rods 12 rotatably connected to the left and right sides of the strip base 11. The rotation axis of the support rods 12 is a vertical axis. When the generator set needs to be used for power generation, the support rods 12 are swung and unfolded. The support rods 12 on both sides of the strip base 11 can respectively prevent the generator set from tipping toward the side as a whole, so that the generator set can be placed stably for use by users. When the generator set is not needed, it is only necessary to swing the support rods 12 on both sides of the strip base 11 toward the strip base 11 so that the support rods 12 are folded and fit on the side of the strip base 11, which can also reduce the space occupied by the generator set and facilitate storage and carrying.
[0033] The above-mentioned power generation device includes a three-phase AC permanent magnet generator 6, a rectifier 5 and a battery 4. The three-phase AC permanent magnet generator 6 is electrically connected to the charging interface of the battery 4 through the rectifier 5. The AC power generated by the three-phase AC permanent magnet generator 6 is rectified by the rectifier 5 and then transmitted to the battery 4 for storage. Compared with the excitation generator, the three-phase AC permanent magnet generator 6 does not need to consume additional electric energy for excitation, has no excitation loss, can save energy, and thus improve the power generation efficiency of the generator, and can also reduce the manpower required to fully charge the battery 4 during the power generation process.
[0034] The three-phase AC permanent magnet generator 6 in this embodiment is a multi-stage fractional slot square wave generator, wherein the rotor 62 in the generator is surrounded by the stator 61, and the stator 61 includes 40 stator 61 teeth, thereby separating 40 stator 61 slots. The outer periphery of the rotor 62 is provided with 51 magnetic poles, forming a fractional slot generator, which has the characteristics of small starting torque, good low-speed power generation performance, high output power, and is convenient for users to use.
[0035] A handle 2 for the user to hold, a saddle 3 for the user to sit on, and a pedal structure 13 are provided above the strip base 11. The handle 2, the pedal structure 13, and the saddle 3 are arranged in the horizontal direction along the length direction of the strip base 11. The pedal structure 13 is rotatably matched with the strip base 11, and the pedal structure 13 is transmission-connected to the rotor 62 of the three-phase AC permanent magnet generator 6 for user convenience.
[0036] Specifically, a connection structure 21 is provided between the bar-shaped base 11 and the handle 2. The connection structure 21 is rotatably connected to the bar-shaped base 11, and the rotation axis of the connection structure 21 is parallel to the width direction of the bar-shaped base 11. The bar-shaped base 11 is also equipped with a third bolt 111 for locking the rotation angle of the connection structure 21. The third bolt 111 is in threaded cooperation with the bar-shaped base 11. When the third bolt 111 is screwed into the bar-shaped base 11 until the threaded end of the third bolt 111 abuts against the connection structure 21, the rotation angle of the connection structure 21 can be locked. By adjusting the rotation angle of the connection structure 21, the horizontal distance between the handle 2 and the saddle 3 can be changed, making the generator set suitable for different users. Moreover, when the handle 2 is rotated close to the saddle 3, the overall space occupied by the generator set can also be reduced, facilitating the movement or storage of the generator set.
[0037] In addition, the handle 2 includes a main body 22 connected to the connection structure 21 and two handle segments 23 rotatably connected to the main body 22. The two handle segments 23 are respectively located on both sides of the main body 22 for the user to hold with both hands. One end of the handle segment 23 is rotatably connected to the main body 22, and the other end can rotate close to or away from the saddle 3. When the generator set is not needed, the two handle segments 23 can be controlled to rotate towards the saddle 3 to make the handle segments 23 fold up, facilitating the reduction of the space occupied by the handle 2. A limiting structure 221 that hinders the handle segment 23 from rotating away from the saddle 3 is also provided on the side of the main body 22 facing away from the saddle 3. When the user sits on the saddle 3 and uses the generator set to generate electricity, a part of the user's weight is transmitted to the handle segment 23 through the hand, pushing the handle segment 23 to abut against the limiting structure 221, and the limiting structure 221 hinders the handle segment 23 from rotating away from the saddle 3, which can keep the position of the handle segment 23 stable for the user to use.
[0038] In this embodiment, the bar-shaped base 11 is connected to a first sleeve 31 extending upward. A seat adjustment rod 32 is slidably arranged in the first sleeve 31. A first bolt 33 for locking the position of the seat adjustment rod 32 is threadedly connected to the side of the first sleeve 31. The saddle 3 is connected to the top end of the seat adjustment rod 32 and moves with the seat adjustment rod 32. The threaded end of the first bolt 33 passes through the side of the first sleeve 31 and abuts against the side of the seat adjustment rod 32 in the first sleeve 31, thereby locking the position of the seat adjustment rod 32.
[0039] In addition, the above-mentioned connection structure 21 includes a second sleeve 211 and a handle adjusting rod 212 inserted into and slidably engaged with the second sleeve 211. The bottom end of the second sleeve 211 is connected to the strip-shaped base 11, and the top end of the second sleeve 211 extends upward. A second bolt 213 for locking the position of the handle adjusting rod 212 is also threadedly connected to the side of the second sleeve 211. The handle 2 is connected to the top end of the handle adjusting rod 212 and moves with the handle adjusting rod 212. The threaded end of the second bolt 213 passes through the side of the second sleeve 211 and abuts against the side of the handle adjusting rod 212 inside the second sleeve 211, thereby locking the position of the handle adjusting rod 212.
[0040] When the user uses the generator set, the user can slide the seat adjusting rod 32 and the handle adjusting rod 212 in the corresponding sleeves and re-lock them with the corresponding bolts, so as to adjust the height positions of the saddle 3 and the handle 2, making the generator set suitable for different users. In addition, when adjusting the height positions of the saddle 3 and the handle 2, the overall space occupied by the generator set can also be adjusted. By reducing the height positions of the saddle 3 and the handle 2, the overall space occupied by the generator set can be conveniently reduced, facilitating the movement or storage of the generator set.
[0041] In addition, the storage battery 4 in this embodiment includes a charging socket and a discharging socket 41. The charging socket is electrically connected to the output port of the rectifier 5. The discharging socket 41 includes a 20V discharging socket 41 and a 5V discharging socket 41. The 20V discharging socket 41 can be used for an LED lamp, a 5W bulb, or a laptop computer; the 5V discharging socket 41 can be used to charge a mobile phone or charge and use other small electrical appliances with a qualified voltage. It should be noted that the specifications of the discharging socket 41 can be configured according to different requirements or directly be a universal socket, which is not limited in this solution.
[0042] A cooling fan is also installed beside the rectifier 5 and the storage battery 4 to facilitate discharging the heat generated during the charging process by the cooling fan and reducing potential safety hazards.
[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0044] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
