[0046] like Figures 1-8 As shown, in this embodiment, the electric bicycle child seat includes a mounting frame 1, a seat cushion 2, and a locking mechanism 4. The mounting frame 1 is mounted on the frame 100, and the seat cushion 2 is located inside the storage compartment 200, with the seat cushion 2 rotatably mounted on the mounting frame 1. The seat cushion 2 is provided with a support member 3, allowing it to rotate relative to the mounting frame 1 to be in a folded state and a passenger-carrying state. When the seat cushion 2 is in the passenger-carrying state, the support member 3 supports the mounting frame 1. The locking mechanism 4 includes a locking tongue 41 and a locking ring 42. The locking tongue 41 is movably mounted on either the seat cushion 2 or the mounting frame 1, and the locking ring 42 is mounted on the other. When the seat cushion 2 is in the folded state, the support member 3 separates from the mounting frame 1, and the locking tongue 41 can be inserted into the locking ring 42, thus fixing the seat cushion 2 relative to the mounting frame 1.

[0047] For example, the electric bicycle is an E-cargo model, and a storage box 200 is installed in front of or behind the frame 100 along the front-rear direction of the bicycle body. The storage box 200 is used to temporarily store items.

[0048] Mounting bracket 1 is fixedly mounted to the frame 100 by several screws, and extends into the storage compartment 200. A seat cushion 2 is disposed within the storage compartment 200. One side of the seat cushion 2 is rotatably connected to the side adjacent to the mounting bracket 1 and has a rotation center line. A support member 3 protrudes from the bottom of the seat cushion 2. The support member 3 and the seat cushion 2 are integrally formed by casting or other methods. The support member 3 has a triangular structure, with one right-angled side connected to the seat cushion 2 and the other right-angled side abutting against the mounting bracket 1. The seat cushion 2 can rotate relative to the mounting bracket 1 around the rotation center line, allowing it to be in a folded or passenger-carrying state. The seat cushion 2 can also rotate downwards relative to the mounting bracket 1 until the support member 3 abuts against the surface of the mounting bracket 1. At this point, the horizontal plane of the seat cushion 2 is nearly parallel to the bottom wall of the storage compartment 200. The seat cushion 2 is supported by the support member 3 and can be used for child riding.

[0049] At the center line of rotation, the locking ring 42 is fixedly connected to the mounting bracket 1, and the locking tongue 41 is movably mounted on the seat cushion 2. The locking tongue 41 can slide relative to the seat cushion 2 to engage or disengage with the locking tongue 41. Optionally, at the center line of rotation, the locking ring 42 is fixedly connected to the seat cushion 2, and the locking tongue 41 is movably mounted on the mounting bracket 1. The locking tongue 41 can slide relative to the mounting bracket 1 to engage or disengage with the locking tongue 41. In this embodiment, the locking ring 42 remains stationary, while the locking tongue 41 rotates synchronously with the seat cushion 2. When the seat cushion 2 is in a loaded state, the locking tongue 41 and the locking ring 42 are misaligned, making engagement and locking impossible. When the seat cushion 2 is not needed for carrying passengers and needs to be stored, the seat cushion 2 can be flipped upward relative to the mounting frame 1, and the support 3 separates from the mounting frame 1. Until the seat cushion 2 is flipped to a certain angle relative to the mounting frame 1, when the locking tongue 41 and the locking ring 42 are aligned, the locking tongue 41 is moved, and the locking tongue 41 slides relative to the seat cushion 2 and is inserted into the locking ring 42. The locking tongue 41 and the locking ring 42 are relatively fixed, so that the seat cushion 2 is fixed relative to the mounting frame 1. At this time, the seat cushion 2 is in a folded state, and the seat cushion 2 can be pressed against the frame 100 or the seat cushion 2 can be kept vertical along the height direction of the vehicle body. The locking effect is good, and the seat is prevented from flipping back and forth and being damaged or even generating noise when the electric bicycle is in a situation such as sudden braking, rapid acceleration, going up and down steep slopes, loading and unloading goods.

[0050] The operating mode of this electric bicycle child seat is as follows: When carrying a child, the seat cushion 2 can flip downwards relative to the mounting frame 1 until the support member 3 abuts against the surface of the mounting frame 1. The seat cushion 2 is supported by the support member 3 and used for child seating. The seat cushion 2 is in a borne position, which is convenient for sitting, and the child's feet can move within the storage box 200. When not carrying a child, the seat cushion 2 can flip upwards relative to the mounting frame 1, and the support member 3 separates from the mounting frame 1 until the locking tongue 41 and the locking ring 42 are aligned. By moving the locking tongue 41, the locking tongue 41 slides relative to the seat cushion 2 and engages with the locking ring 42. The locking tongue 41 and the locking ring 42 are relatively fixed, thereby fixing the seat cushion 2 relative to the mounting frame 1. At this time, the seat cushion 2 is in a folded state, which is convenient for storage. The mode switching is quick, and the seat does not occupy the storage space of the storage box 200.

[0051] Furthermore, referring to Figures 1-8 The locking mechanism 4 also includes a mounting base 43, which is mounted on either the seat 2 or the mounting bracket 1. The locking tongue 41 includes a sliding part 411, a plugging part 412, and a toggle part 413. The sliding part 411 is slidably disposed in the mounting base 43. The mounting base 43 has a connecting hole 431. The toggle part 413 is slidably located in the connecting hole 431, so that the plugging part 412 can be plugged into or separated from the locking ring 42.

[0052] Mounting base 43 is screwed to the rotation center line of seat 2. Mounting base 43 has an inner cavity, and sliding part 411 is located in the inner cavity of mounting base 43, and sliding part 411 can slide relative to mounting base 43. A connecting hole 431 is opened at the bottom of mounting base 43. One end of actuating part 413 is connected to sliding part 411, and the other end passes through connecting hole 431 and protrudes relative to mounting base 43. The thickness of actuating part 413 is much smaller than the inner diameter of connecting hole 431, so that actuating part 413 can reciprocate within connecting hole 431 under the action of external force. A locking hole is opened on the side wall of mounting base 43 near locking ring 42. One end of insertion part 412 is connected to sliding part 411, and the other end can slide through the locking hole.

[0053] When the seat switches from a passenger-carrying position to a folded position, the user applies pressure to the bottom or edge of the seat cushion 2 and lifts it. The seat cushion 2 can then flip upwards relative to the mounting bracket 1, separating the support member 3 from the mounting bracket 1 until the locking tongue 41 and the locking ring 42 are aligned. Then, by pushing the actuating part 413 with a finger, the sliding part 411 slides within the mounting base 43, and the insertion part 412 slides through the lock hole and gradually approaches the locking ring 42. Finally, the insertion part 412 is inserted into the locking ring 42, fixing the seat cushion 2 relative to the mounting bracket 1. At this time, the seat cushion 2 is in a folded state and remains fixed, providing a good locking effect.

[0054] When switching the seat from a folded state to a passenger-carrying state, push the lever 413 in the opposite direction with your finger. The sliding part 411 slides in the opposite direction within the mounting base 43, and the insertion part 412 slides through the lock hole and gradually moves away from the locking ring 42. The insertion part 412 separates from the locking ring 42, at which point the seat cushion 2 is unlocked. Then, the user applies pressure to the surface or edge of the seat cushion 2, and the seat cushion 2 can flip downward relative to the mounting frame 1 until the support 3 abuts against the surface of the mounting frame 1. The seat cushion 2 is then in the passenger-carrying state, and the seat cushion 2 can be supported by the mounting frame 1 and used for children to sit in, making it convenient for them to ride.

[0055] Furthermore, referring to Figures 1-8 One of the seat cushion 2 and the mounting bracket 1 is provided with a boss 5, the boss 5 has a slot 51, and the mounting base 43 is provided with a hook 432, which is engaged with the slot 51.

[0056] The boss 5 has a U-shaped longitudinal section. It is fixedly installed on the rotation center line of the seat cushion 2 by welding or other methods. The side wall of the boss 5 has a slot 51, and the mounting base 43 has a matching hook 432. Through the engagement of the hook 432 with the slot 51, the mounting base 43 is quickly installed on the seat cushion 2, facilitating easy installation and removal. Optionally, the boss 5 is fixedly installed on the rotation center line of the mounting bracket 1, and the mounting base 43 is quickly installed on the seat cushion 2 through the engagement of the hook 432 with the slot 51. Preferably, there are two slots 51 and two hooks 432. Slots 51 are provided on the left and right side walls of the boss 5, and hooks 432 protrude from the left and right side walls of the mounting base 43. The two hooks 432 engage with the corresponding slots 51 through elastic deformation, further enhancing the fixing effect of the mounting base 43 and preventing it from loosening and detaching from the boss 5.

[0057] Furthermore, referring to Figures 1-8 The locking mechanism 4 also includes an elastic element 44, which is located inside the mounting base 43. One end of the elastic element 44 is connected to the sliding part 411, and the other end of the elastic element 44 is connected to the inner side wall of the mounting base 43. The elastic element 44 is always in a compressed state.

[0058] The elastic element 44 is configured as a compression spring. Under the elastic action of the elastic element 44, the sliding part 411 always extends relative to the locking hole. When the seat cushion 2 is in the folded state, the insertion part 412 is inserted into the locking ring 42. At the same time, the elastic element 44 applies a certain force to the insertion part 412 to ensure that the insertion part 412 is always inserted into the locking ring 42, so as to prevent the insertion part 412 from disengaging from the locking ring 42 under the circumstances of electric bicycle shaking or severe vibration, which would cause the folded state of the seat cushion 2 to fail. When the seat cushion 2 is switched from the folded state to the carrying state, the actuating part 413 is pushed in the opposite direction with a certain force by the finger. The sliding part 411 slides in the opposite direction in the mounting base 43, the elastic element 44 is gradually compressed, the plug part 412 separates from the locking ring 42, the seat cushion 2 flips downward relative to the mounting frame 1, and at the same time, the actuating part 413 is released. Under the elastic action of the elastic element 44, the actuating part 413 returns to the initial position. When the seat cushion 2 is switched to the carrying state, the relative positions between the actuating part 413 and the locking ring 42 are misaligned and do not affect each other.

[0059] Furthermore, referring to Figures 1-8 The seat cushion 2 has a relief groove 21, which is configured to avoid the locking ring 42.

[0060] When the seat cushion 2 is in the passenger position, the support member 3 abuts against the surface of the mounting frame 1. The horizontal plane where the seat cushion 2 is located is nearly parallel to the bottom wall of the storage box 200. A part of the structure of the locking ring 42 is located in the clearance groove 21 to ensure that there is no structural interference between the locking ring 42 and the seat cushion 2.

[0061] Furthermore, referring to Figures 1-8 It also includes a fixing frame 6 and a first connecting member 7. The fixing frame 6 is installed on the vehicle frame 100. The fixing frame 6 has a mounting hole. The mounting frame 1 has an adjustment hole 11. The first connecting member 7 can slide along the length direction of the adjustment hole 11 and can pass through the adjustment hole 11 and be connected to the mounting hole.

[0062] The mounting bracket 6 is installed on the frame 100 with screws. The child seat can be detachably installed on the frame 100 via the mounting bracket 6, which can adapt to different sizes of electric bicycles, has a wide range of applications, strong versatility, and reduces the production cost and inventory management of child seats. The first connecting piece 7 is set as a fixing screw, and the adjustment hole 11 has an oblong hole structure. According to the different heights of different children, the first connecting piece 7 is loosened, and the mounting bracket 1 can be adjusted up and down relative to the frame 100 along the height direction of the vehicle body. The first connecting piece 7 can slide up and down along the extension direction of the adjustment hole 11. Then, the first connecting piece 7 is locked so that the child seat can meet the height requirements of the child and ensure the comfort of the child when riding.

[0063] Furthermore, referring to Figures 1-8It also includes a rotating assembly 8, which includes a fixing member 81, a bushing 82, a nut 83, and a washer 84. The bushing 82 is disposed on the seat 2, the nut 83 is disposed on the mounting bracket 1, the fixing member 81 passes through the bushing 82 and is connected to the nut 83, the bushing 82 can rotate relative to the fixing member 81, the washer 84 is disposed on the seat 2, and the inner ring of the washer 84 is in contact with the outer ring of the bushing 82, and the washer 84 abuts against the fixing member 81.

[0064] The fixing member 81 is configured as a fixing screw. The bushing 82 is fixedly nested in the center of rotation of the seat 2 via a washer 84, i.e., inside the connecting tube of the seat 2. Correspondingly, the nut 83 is fixedly nested in the center of rotation of the mounting bracket 1, i.e., inside the connecting tube of the mounting bracket 1. The outer circumference of the fixing member 81 is clearance-fitted with the inner ring of the bushing 82, and the tail of the fixing member 81 is threadedly connected to the nut 83. When the seat 2 is flipped, the seat 2 can drive the bushing 82 to rotate relative to the fixing member 81, while the mounting bracket 1 and the nut 83 remain stationary, thereby achieving a smooth rotational engagement between the seat 2 and the mounting bracket 1.

[0065] Furthermore, referring to Figures 1-8 It also includes a second connector 9. The seat cushion 2 includes a support 22 and a gasket 23. The support 22 has a through hole, and the gasket 23 has a connection hole. The second connector 9 passes through the through hole and is connected to the connection hole. The second connector 9 is configured as a fixing screw. The gasket 23 is made of hard or soft leather material. The gasket 23 can be removed from the support 22 through the second connector 9 for easy replacement and maintenance.

[0066] This embodiment also provides a bicycle, including a frame 100 and a child seat for power-assisted bicycles. There are two child seats for power-assisted bicycles, which are respectively installed at both ends of the frame 100 along the front-rear direction of the bicycle.

[0067] The storage compartment 200 of the E-cargo model electric bicycle is longer along the front-to-back direction of the bicycle, allowing for more storage. Child seats are located at both the front and rear of the storage compartment 200, enabling two children to ride on the bicycle, making it highly practical. When carrying a child, the seat 2 can be flipped downwards relative to the mounting frame 1 until the support member 3 abuts against the surface of the mounting frame 1. The seat 2 is then supported by the support member 3 and used for child seating. In this seated position, the child's feet can move freely within the storage compartment 200. When not carrying a child, the seat 2 can be flipped upwards relative to the mounting frame 1, separating the support member 3 from the mounting frame 1 until the locking tongue 41 and the locking ring 42 are aligned. Move the latch 41, and the latch 41 slides relative to the seat cushion 2 and is inserted into the locking ring 42. The latch 41 and the locking ring 42 are relatively fixed, so that the seat cushion 2 is fixed relative to the mounting bracket 1. At this time, the seat cushion 2 is in a folded state, which is convenient for storage. The mode switching is quick, and the seat does not occupy the storage space of the storage box 200.
