Description

Technical Field

[0001] This application relates to the field of fitness and recreational facilities, and in particular to a children's bouncy car. Background Technology

[0002] With the development of the times, people's living conditions and consumption concepts are constantly changing. For example, nowadays, family spending is mostly focused on children's education. One of the most significant developments in children's education is the increase in children's entertainment equipment. Many children's entertainment devices are constantly being updated and modified to better suit children's interests and requirements in areas such as entertainment, education, or fitness.

[0003] Children's vehicles are a major category of children's entertainment equipment. With continuous development, the variety of children's vehicles has increased significantly. Currently, the most common types on the market include bicycles, tricycles, strollers, baby walkers, electric toy cars, balance bikes, and more. These various children's vehicles meet children's different play needs; for example, balance bikes can help develop children's balance.

[0004] So, how to modify strollers to meet the different play needs of children, thereby improving the competitiveness of businesses in the stroller industry, is a technical problem that needs to be solved. Summary of the Invention

[0005] In order to modify children's vehicles to meet the different play needs of children, and to enhance children's entertainment while strengthening their exercise, this application provides a children's bouncy vehicle.

[0006] The technical solution for a children's bouncy vehicle provided in this application is as follows:

[0007] A children's bouncy car, comprising:

[0008] Frame;

[0009] The rotating mechanism includes a rotating rod hinged to the frame, the rotating rod having a saddle mounting portion for mounting a saddle, allowing the child's feet to touch the ground when sitting on the saddle; when the saddle is subjected to downward pressure from the child, the rotating rod can rotate downward about its hinge axis with the frame.

[0010] A reset element is mounted on the frame and connected to the rotating mechanism. When the child jumps upward, the rotating rod rotates upward around its hinge axis with the frame under the action of the reset element.

[0011] The transmission mechanism includes a rotating shaft rotatably connected to the frame and a transmission assembly connecting the rotating shaft and the rotating rod; when the rotating rod rotates upward or downward, the transmission mechanism drives the rotating shaft to rotate; the rotating shaft is used to mount a drive wheel, enabling the frame to move forward under the drive of the drive wheel.

[0012] By adopting the above technical solution, when using this children's bouncer, the child sits on the saddle with both feet on the ground. The child then bounces up and down repeatedly, using leg strength to jump upwards.

[0013] When a child sits on the saddle, the child applies downward pressure to the saddle. At this time, the rotating link, driven by the saddle, rotates downwards along its hinge axis with the frame. When the child jumps upwards, the downward pressure applied to the saddle decreases or even disappears. The rotating link, under the action of the reset mechanism, rotates upwards around its hinge axis with the frame until it reaches the child's jump height. When the child falls, the child applies downward pressure to the saddle again, causing the rotating link to rotate downwards again around its hinge axis with the frame until it reaches the child's minimum downward pressure. This cycle repeats, with the child's jumping and downward pressure causing the rotating link to rotate back and forth around its hinge axis with the frame.

[0014] When the rotating rod rotates upward or downward, it will drive the rotating shaft to rotate through the transmission mechanism, thereby driving the power wheel mounted on the rotating shaft to rotate, and thus driving the frame forward.

[0015] In this process, it not only meets the needs of children riding outdoors, but also enhances their entertainment and exercise. It combines children's bikes with a bouncing control system, making this children's bouncing bike different from existing children's bikes on the market. It can meet the different play needs of children, thereby improving the competitiveness of businesses in the children's bike industry.

[0016] Optionally, the rotating rod extends in a direction away from the frame, with one end of the rotating rod away from the frame suspended in the air, and the saddle mounting portion located at the suspended end of the rotating rod.

[0017] By adopting the above technical solution, the rotation range of the rotating rod can be guaranteed, enabling the frame to move forward by rotating the rotating rod. This makes operation easier and more convenient for children to operate the rotating rod.

[0018] Optionally, both the rotating rod and the saddle mounting portion are located on the side of the frame facing the forward direction.

[0019] By adopting the above technical solution, when a child sits on the saddle, the frame is located behind the child, which gives the child a wider field of vision as the child moves the frame forward.

[0020] Optionally, the rotating rod includes a transmission rod hinged to the frame, the transmission rod extending away from the frame, and one end of the transmission rod away from the frame being connected to the saddle mounting portion.

[0021] By adopting the above technical solution, when a child sits on the saddle mounting part, the transmission rod can be driven to rotate downward; when the force applied by the child on the saddle mounting part disappears, the rotating rod moves upward under the action of the reset member, so as to realize the rotation of the rotating rod within a certain range.

[0022] Optionally, the rotating rod includes two parallel and vertically spaced transmission rods. The two transmission rods extend away from the vehicle frame, and both ends of each transmission rod are hinged to the vehicle frame and the saddle mounting part, respectively, so that the saddle mounting part remains horizontal during the rotation of the transmission rods. The transmission assembly is connected to the transmission rods.

[0023] By adopting the above technical solution, the saddle mounting part can maintain a horizontal state when moving with the rotation of the transmission rod, so that the saddle installed in the saddle mounting part is always in a horizontal state, ensuring the stability of the child when sitting on the saddle.

[0024] Optionally, the transmission rod is provided with two rods, which are parallel and vertically spaced apart to form a group. The rotating rod includes two groups of transmission rods, which are located on opposite sides of the saddle mounting part.

[0025] The rotating rod also includes a connecting rod hinged to the two sets of transmission rods, and the connecting rod is the saddle mounting part.

[0026] By adopting the above technical solution, the saddle mounting part can be supported by two sets of transmission rods at the same time, enabling the saddle mounting part to withstand a greater load and meet the needs of children of different weights; at the same time, the frame can also be supported by two sets of transmission rods at the same time, making the saddle mounting part more stable.

[0027] Optionally, the rotating rod may further include a reinforcing rod fixed between the two sets of transmission rods.

[0028] By adopting the above technical solution, the support strength of the two sets of transmission rods can be increased, avoiding situations such as bending in the middle due to excessive length of the transmission rods.

[0029] Optionally, the frame includes a main frame for mounting the rotating shaft and a support rod fixed to the main frame, the support rod being hinged to the rotating member.

[0030] By adopting the above technical solution, the rotating rod is installed on the receiving rod to realize the connection between the rotating rod and the receiving rod. The structure is simple and lightweight, making it easy for children to operate the children's bouncy car.

[0031] Optionally, the frame further includes a support rod fixed to the main frame and extending upward, the support rod having a fulcrum rod configured as a fulcrum, and the reset member supported on the fulcrum rod to form a lever structure.

[0032] By adopting the above technical solution, the lever structure is used to hold and fix the rotating rod.

[0033] Optionally, the reset component includes an elastic band that passes around the fulcrum rod, with both ends of the elastic band connected to the rotating rod and the vehicle frame, respectively.

[0034] By adopting the above technical solution, the rotating rod can be held by the elastic band. When the rotating rod rotates downward, the elastic band is stretched. When the force applied to the saddle disappears, the rotating rod returns to its original position under the elastic force of the elastic band. The structure is simple, lightweight, easy to process and assemble, and has a low cost.

[0035] Optionally, the rotating shaft is provided with one shaft, and the drive wheels are provided at both ends of the rotating shaft. The children's bouncy car also includes a connecting frame provided in the middle of the rotating shaft. The connecting frame is used to provide support wheels with a diameter smaller than that of the drive wheels. The frame is kept horizontal under the action of the support wheels and the drive wheels; or:

[0036] At least two rotating shafts are spaced apart along the forward direction of the vehicle frame, and the two ends of each rotating shaft are used to mount the drive wheel. The transmission assembly is connected to any one of the rotating shafts.

[0037] By adopting the above technical solution, the frame is kept horizontal under normal conditions, thus maintaining the frame's stability.

[0038] Optionally, when there is only one rotating shaft, the connecting frame is located on the side of the rotating shaft facing the rotating rod, and a shock absorber is provided between the connecting frame and the vehicle frame.

[0039] By adopting the above technical solution, the shock absorber can buffer and reduce the impact on the frame. When the force applied by the child to the saddle is large, the shock absorber can also buffer the force applied to the saddle mounting part, ensuring the stability of the frame and reducing the risk of the frame tipping over.

[0040] Optionally, the transmission assembly includes a drive wheel sleeved on the rotating rod, a driven wheel fixed to the rotating shaft, and a conveyor belt / chain connecting the drive wheel and the driven wheel. When there is only one rotating shaft, the connecting frame is located on the side of the rotating shaft facing the rotating rod, and a shock absorber is provided between the connecting frame and the vehicle frame.

[0041] By adopting the above technical solution, when the rotating rod rotates around its hinge axis with the frame, it will also drive the drive wheel mounted on the rotating rod to rotate. The drive wheel will drive the driven wheel to rotate via a conveyor belt / chain, which in turn drives the rotating shaft fixed to the driven wheel to rotate, thereby driving the power wheel mounted on the rotating shaft to rotate, thus moving the frame. Due to the ratchet and pawl mechanism, when the rotating rod reciprocates, it only drives the drive wheel to rotate when the rotating rod rotates upwards or downwards, thus moving the frame in one direction.

[0042] Optionally, a handrail is provided at the end of the rotating rod away from the vehicle frame.

[0043] By adopting the above technical solution, it is easier for children to hold onto.

[0044] Optionally, the children's bouncy car also includes the saddle and the drive wheel.

[0045] By adopting the above technical solutions, a complete children's bouncy car is formed.

[0046] In summary, this application includes at least one of the following beneficial technical effects:

[0047] 1. This application proposes a children's bouncy bike that combines a children's bike with a bouncy control system by modifying the children's bike. This not only allows children to ride outdoors, but also enhances their entertainment, strengthens their exercise, and effectively increases the competitiveness of businesses.

[0048] 2. By setting the end of the rotating rod away from the frame to be suspended in the air, the child only needs to rotate the rotating rod when jumping, making the operation more effortless; and there is nothing below to obstruct the child, making it easier for the child to reach the ground smoothly after jumping.

[0049] 3. The design of the support rod and the fulcrum rod allows the reset component to be supported on the fulcrum rod to form a lever structure, making it easier for children to apply force to the rotating rod to make it rotate.

[0050] 4. The overall structure of the children's bouncy car of this application is simple, compact, and lightweight, making it easy for children to operate. Attached Figure Description

[0055] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0056] This application discloses a children's bouncy car. (See also...) Figure 1 and Figure 2 The children's bouncy car includes a frame 1, a rotating mechanism 2 hinged to the frame 1, and a reset member 4 disposed between the frame 1 and the rotating mechanism 2. One end of the rotating mechanism 2 is hinged to the frame 1, and the end of the rotating mechanism 2 away from the frame 1 forms a saddle mounting portion 23 for mounting a saddle 3. When a child sits on the saddle 3 in the saddle mounting portion 23 and applies a downward force to the saddle 3, the rotating mechanism 2 will move downward about its hinge axis with the frame 1; when the force applied by the child on the saddle 3 disappears, the reset member 4 can drive the rotating mechanism 2 to rotate upward about its hinge axis with the frame 1 to achieve reset, thereby driving the rotating mechanism 2 to reciprocate. When a child sits on the saddle 3 and jumps, the cooperation between the child and the reset member 4 can drive the rotating mechanism 2 to reciprocate, simulating a trampoline, seesaw, and other recreational equipment, providing entertainment and exercise for the child.

[0057] Reference Figure 1 and Figure 2The frame 1 includes a main frame 11 that is generally flat and frame-shaped, and a support rod 12 fixed to the main frame 11 for connection with the rotating mechanism 2. The support rod 12 extends upward and is located at one end of the frame 1. The rods constituting the main frame 11 can be hollow metal rods, which makes the overall cost of the children's bouncy bike lower and its weight lighter.

[0058] The rotating mechanism 2 includes a rotating rod 21 hinged to the receiving rod 12. One end of the rotating rod 21, away from the receiving rod 12, extends away from the frame 1, and the other end of the rotating rod 21 is suspended in the air. This suspended end forms the saddle mounting portion 23 for mounting the saddle 3. When a child sits on the saddle 3, their feet can touch the ground. When the child applies a downward force to the saddle 3, the rotating rod 21 rotates downward around its hinge axis with the frame 1. When the child jumps upward, the force applied to the saddle 3 disappears, and the rotating rod 21 rotates upward around its hinge axis with the receiving rod 12 under the action of the reset member 4. This allows the rotating rod 21 to rotate back and forth simply by the child jumping. Since the saddle mounting portion 23 is located at the suspended end of the rotating rod 21, there are no obstructions below when the child jumps while sitting on the saddle 3, allowing their feet to smoothly contact the ground.

[0059] Specifically, the rotating rod 21 includes a transmission rod 211 hinged between the frame 1 and the saddle mounting part 23. There can be one transmission rod 211, which drives the saddle mounting part 23 to reciprocate. Alternatively, there can be two transmission rods 211, which are parallel and spaced apart in the vertical direction. The ends of the two transmission rods 211 facing the receiving rod 12 are hinged to the receiving rod 12, and the hinge axes of the two transmission rods 211 and the receiving rod 12 are located in the same vertical plane. The ends of the two transmission rods 211 away from the receiving rod 12 are hinged to the saddle mounting part 23, so that the receiving rod 12, the two transmission rods 211 and the saddle mounting part 23 form a parallelogram structure in space. When a child sits on the saddle 3 and drives the transmission rod 211 to rotate downwards, or when the transmission rod 211 rotates upwards under the action of the reset member 4, the saddle 3 remains in a horizontal state. The saddle 3 will not tilt due to the transmission rod 211 rotating in an arc, thus ensuring the stability of the child when sitting on the saddle 3.

[0060] In this configuration, two parallel transmission rods 211 spaced apart in the vertical direction form a group. The rotating rod 21 may also include two groups of transmission rods 211. The two groups of transmission rods 211 are located on opposite sides of the saddle mounting portion 23 and are mirror images of each other about the centerline of the width direction of the saddle mounting portion 23. This allows the saddle mounting portion 23 to be supported and fixed by the two groups of transmission rods 211, thereby improving the installation firmness of the saddle mounting portion 23 and enabling the saddle 3 mounted on the saddle mounting portion 23 to withstand a greater load.

[0061] The rotating rod 21 also includes a connecting rod 212 located between the two sets of transmission rods 211 and simultaneously hinged to the two sets of transmission rods 211. The connecting rod 212 is hinged to the end of the transmission rod 211 away from the receiving rod 12. The connecting rod 212 is the aforementioned saddle mounting part 23.

[0062] To increase the support between the two sets of rotating rods 21 and maintain their synchronization, a reinforcing rod 213 is fixed between the two sets of rotating rods 21. Two reinforcing rods 213 are provided, and the two reinforcing rods 213 are respectively connected to the two transmission rods 211 corresponding to the two sets of rotating rods 211.

[0063] Among them, the transmission rod 211, connecting rod 212 and reinforcing rod 213 can all be made of hollow metal rods, which makes the overall weight of the children's bouncy car lighter and can also reduce costs.

[0064] Reference Figure 1 and Figure 2 The frame 1 also includes a support rod 13 fixed to the main frame 11. The support rod 13 includes two identical support rods 131, which are spaced apart along the width of the main frame 11. Both ends of each support rod 131 are fixed to the main frame 11, and the middle of the support rod 131 extends upward, making the two support rods 131 form an inverted V shape. A fulcrum rod 132 is fixed between the two support rods 131. One end of the reset member 4 is connected to the rotating rod 21, and the middle of the reset member 4 is supported on the fulcrum rod 132 to form a lever structure, thereby providing an upward pulling force to the rotating rod 21 and realizing the reset of the rotating rod 21.

[0065] Reference Figure 1In one example of this application, the reset member 4 includes an elastic band 41 fixed between the rotating rod 21 and the frame 1, with the middle portion of the elastic band 41 passing over the fulcrum rod 132. Specifically, one end of the elastic band 41 can be directly connected to any reinforcing rod 213 on the rotating rod 21, and the other end of the elastic band 41 can be connected to the main frame 11 or to the support rod 13. The connection point between the elastic band 41 and the main frame 11 or the elastic band 41 and the support rod 13 is lower than the height of the fulcrum rod 132. This application uses the example of the elastic band 41 being connected to the support rod 13 for illustration. In this case, a fixing rod 133 for fixing the elastic band 41 is fixed between the two support rods 131, and the elastic band 41 is fixed to the fixing rod 133 to achieve the pulling of the rotating rod 21. Under normal conditions, the rotating rod 21 remains in a balanced state under the elastic force of the elastic band 41. When a child sits on the saddle 3 and applies a downward force to the rotating rod 21, the elastic band 41 will be stretched. When the force applied to the rotating rod 21 disappears, the rotating rod 21 will move upward and reset under the elastic force of the elastic band 41.

[0066] Among them, the elastic band 41 can be made of natural latex (the same material as the elastic bands in the gym). Of course, the elastic band 41 can also be made of other materials, as long as it can be stretched under force and can recover after the force is removed.

[0067] Understandably, the reset component 4 can also be a tension spring or the like, as long as it can achieve the pulling and resetting of the rotating rod 21.

[0068] Reference Figure 2 In another example of this application, the reset component 4 includes a rocker arm 42 fixed at one end to the rotating rod 21 and a counterweight 43 fixed at the end of the rocker arm 42 away from the rotating rod 21. The middle part of the rocker arm 42 abuts against the support rod 13, so that the rocker arm 42 as a whole forms a seesaw with the fulcrum rod 132 as the fulcrum. The counterweight 43 can be a counterweight block or a bucket, etc. When a child sits on the saddle 3 and applies a downward force to the saddle 3, the saddle 3 will drive the rotating rod 21 to rotate, and at this time the rocker arm 42 will also rotate around the fulcrum rod 132; when the force applied to the saddle 3 disappears, the weight of the counterweight 43 will drive the rotating rod 21 to move upward to achieve reset.

[0069] Since using a rocker and counterweight would increase the overall weight of the children's bouncy car, this application uses the reset component 4, including the elastic band 41, as an example for explanation. It is understood that the reset component 4 can also be other types of structures, such as springs, as long as it can cause the rotating rod 21 to rotate downwards when the child applies a downward force to the saddle 3; and when the force applied by the child to the rotating rod 21 disappears, the reset component 4 can cause the rotating rod 21 to rotate upwards to reset.

[0070] Reference Figure 1 and Figure 2 Since the elastic band 41, rocker arm, etc. are used to provide the restoring force for the rotating rod 21, the elastic band 41 or rocker arm 42 will slide back and forth relative to the fulcrum rod 132. Therefore, a sliding wheel 134 is rotatably connected to the fulcrum rod 132, and the elastic band 41 or rocker arm 42 abuts against the sliding wheel 134 to reduce the friction between the elastic band 41 and the fulcrum rod 132 or the rocker arm 42 and the fulcrum rod 132, thereby reducing the wear on the elastic band 41 or rocker arm 42.

[0071] Reference Figure 1 and Figure 2 To enable children to exercise and have fun while also being able to travel, a drive wheel 5 is provided on the underside of the frame 1 to drive the frame 1 forward. A transmission mechanism 6 is also provided between the drive wheel 5 and the rotating rod 21 to transmit the force of the rotating rod 21 to the drive wheel 5 so that the drive wheel 5 can rotate.

[0072] Specifically, the transmission mechanism 6 includes a rotating shaft 61 rotatably connected to the frame 1 and a transmission assembly 62 connecting the rotating shaft 61 and the rotating rod 21. The drive wheel 5 is mounted on the rotating shaft 61. When the rotating rod 21 rotates upward or downward, the transmission mechanism 6 drives the rotating shaft 61 to rotate, thereby driving the drive wheel 5 mounted on the rotating shaft 61 to rotate, thus propelling the frame 1 forward. The rotating mechanism 2 can be located on the side of the frame 1 facing the forward direction or on the side of the frame 1 away from the forward direction. This application uses the example of the rotating mechanism 2 being located on the side of the frame 1 facing the forward direction. When a child uses the vehicle, the frame 1 is located behind the child, preventing obstruction and improving the child's field of vision.

[0073] Reference Figure 1 and Figure 2 The transmission assembly 62 includes a driving wheel 621 sleeved on the rotating rod 21, a driven wheel 622 fixed to the rotating shaft 61, and a conveyor belt / chain 623 connecting the driving wheel 621 and the driven wheel 622. A one-way transmission assembly (not shown in the figure) is provided between the rotating rod 21 and the driving wheel 621 to ensure that when the rotating rod 21 rotates in one direction, it can drive the driving wheel 621 to rotate; and when the rotating rod 21 rotates in the opposite direction, it will not be able to drive the driving wheel 621 to rotate.

[0074] The unidirectional transmission component can be a ratchet and pawl mechanism, or other structures capable of unidirectional transmission can be used, as long as it enables the rotating rod 21 to drive the drive wheel 621 when rotating in one direction, and not to drive the drive wheel 621 when rotating in the other direction. This application uses a ratchet and pawl mechanism as an example for unidirectional transmission. The ratchet and pawl structure is a mature technology and easy to install. The specific structure and installation method of the ratchet and pawl mechanism are existing technologies and will not be elaborated in detail here. For specific details, refer to the structure of a bicycle rear wheel. This application uses the example of the rotating rod 21 driving the drive wheel 621 to rotate when the end near the saddle mounting part 23 rotates downwards.

[0075] Specifically, each transmission rod 211 has an outward bend at the end near the receiving rod 12 to form a bend 214. The bend 214 is directly connected to the receiving rod 12 to achieve a hinge connection between the transmission rod 211 and the receiving rod 12. The drive wheel 621 is mounted on the bend 214 of any transmission rod 211. When the transmission rod 211 rotates downward, it drives the drive wheel 621 to rotate through the ratchet and pawl mechanism, which in turn drives the rotating shaft 61 to rotate through the conveyor belt / chain 623, thereby driving the frame 1 forward through the drive wheel 5. When the transmission rod 211 rotates upward, due to the ratchet and pawl mechanism, the transmission rod 211 can only drive the drive wheel 621 to rotate in one direction, and cannot drive the drive wheel 5 to rotate in the opposite direction. This means that the drive wheel 5 can only rotate in one direction to drive the frame 1 forward, and will not drive the frame 1 backward.

[0076] Among them, the driving wheel 621 and the driven wheel 622 can be pulleys, in which case the conveyor belt / chain 623 is a belt; of course, the driving wheel 621 and the driven wheel 622 can also be sprockets, in which case the conveyor belt / chain 623 is a chain.

[0077] Understandably, when the conveyor belt / chain 623 is connected between the drive wheel 621 and the driven wheel 622, if the frame 1 interferes with the conveyor belt / chain 623, a tensioning wheel 63 can be installed on the frame 1. The tensioning wheel 63 can support and guide the conveyor belt / chain 623 to reduce the interference caused by the frame 1; on the other hand, it can also tension the conveyor belt / chain 623 to ensure the normal power transmission of the transmission assembly 62.

[0078] Reference Figure 2In order to ensure that the frame 1 can remain horizontal under normal conditions, in one example of this application, at least two rotating shafts 61 can be provided at intervals along the forward direction of the frame 1. Two drive wheels 5 are installed at the two ends of each rotating shaft 61 respectively. The driven wheel 622 is fixed to any one of the rotating shafts 61. The drive wheels 5 on at least two rotating shafts 61 can provide stable support for the frame 1.

[0079] In this configuration, of the at least two rotating shafts 61, the one not connected to the driven wheel 622 can be a long shaft, with its two ends located on opposite sides of the frame 1. Alternatively, the rotating shaft 61 not connected to the driven wheel 622 can be two short shafts with overlapping axes and spaced apart, located on opposite sides of the frame 1. This ensures that the middle portion of the two short shafts does not interfere with the installation of other components on the frame 1, while also simplifying the overall structure and reducing the overall weight of the frame 1. This application uses two rotating shafts 61 as an example. The rotating shaft 61 located at the rear of the frame 1 is a long shaft used to connect to the driven wheel 622; the rotating shaft 61 located at the front of the frame 1 consists of two short shafts to avoid obstructing the rotation of the rotating rod 21.

[0080] Reference Figure 1 and Figure 3 Of course, in another example of this application, the rotating shaft 61 can also be provided with one shaft. In this case, a connecting frame 64 for mounting the support wheel 65 is also provided in the middle of the rotating shaft 61. The connecting frame 64 is used to mount the support wheel 65 with a diameter smaller than that of the drive wheel 5. The frame 1 can maintain a horizontal state under the joint support of the support wheel 65 and the drive wheel 5.

[0081] The connecting frame 64 is located on the side of the rotating shaft 61 facing the rotating rod 21, and includes a mounting cylinder 641 sleeved on the rotating shaft 61, a first mounting rod 642 vertically fixed to the side wall of the mounting cylinder 641, and a second mounting rod 643 vertically fixed to the end of the first mounting rod 642 away from the mounting cylinder 641. The support wheel 65 is provided with two rods respectively installed at both ends of the second mounting rod 643.

[0082] Reference Figure 3 A shock absorber 66 is also provided between the frame 1 and the connecting frame 64. When the force applied by the child to the rotating rod 21 is too great, the shock absorber 66 can buffer and dampen the frame 1, so as to reduce the phenomenon that the frame 1 will tip forward due to excessive force on the end of the rotating rod 21 near the saddle mounting part 23.

[0083] Specifically, the shock absorber 66 includes a telescopic rod 661 fixed between the frame 1 and the connecting frame 64, and a shock-absorbing spring 662 sleeved on the telescopic rod 661. When the pressure on the saddle 3 is too great, when the rotating rod 21 rotates downward to its limit position, it will directly drive the main frame 11 to rotate downward around the axis of the rotating shaft 61, causing the telescopic rod 661 to contract and the shock-absorbing spring 662 to compress. At this time, the frame 1 can still maintain a horizontal state under the action of the drive wheel 5 and the support wheel 65, ensuring the overall stability of the children's bouncy bike.

[0084] Reference Figure 1 and Figure 2 The rotating mechanism 2 also includes a handrail 22 fixed to the end of the connecting rod 212 away from the frame 1. The handrail 22 can not only be held by children, but also be used by children to control the steering of the children's bouncy car.

[0085] Reference Figure 1 and Figure 2 The children's bouncy car also includes the aforementioned saddle 3 installed in the saddle mounting part 23, the saddle 3 being for the child to sit on.

[0086] Specifically, the saddle 3 can be in any desired form. For example, the saddle 3 can be a seat with railings on three sides, in which case the armrests 22 can be railings surrounding the three sides of the seat.

[0087] Of course, the saddle 3 can also be a horizontal plate or a bicycle seat to simulate a seesaw. In this case, the armrest 22 includes an extension rod 221 that is connected to the connecting rod 212 and extends upward, and a handle 222 that is vertically fixed to the end of the extension rod 221 away from the connecting rod 212. The structure is simple and lightweight.

[0088] Of course, the saddle 3 can also be a fixed structure formed by wrapping the straps into an inverted triangle (refer to a children's walker). The fixed structure has mounting holes for the child's two legs to insert, in order to simulate the fixing method when using a trampoline. In this case, the armrest 22 can be a strap that connects the fixed structure to the connecting rod 212.

[0089] Of course, the saddle 3 can also be other types of structures, and the specific design can be tailored to the needs, as long as it can provide a sitting position for children.

[0090] When the required saddle 3 structure is designed according to the needs, the corresponding armrest 22 structure can be designed according to the form of the saddle 3. Of course, if the child can be fixed in position on the saddle 3 when sitting on it, the armrest 22 structure may not be designed. The specific design can be determined according to the actual needs.

[0091] The implementation principle of a children's bouncy car according to an embodiment of this application is as follows: In use, the child sits on the saddle 3 with both feet either on either side of the saddle and touching the ground, or in front of the saddle and touching the ground. When the child squats down, downward pressure is applied to the saddle 3, causing the rotating rod 21 to rotate downwards. At this time, the rotating rod 21 drives the drive wheel 621 to rotate, which in turn drives the driven wheel 622 to rotate via the conveyor belt / chain 623, thereby driving the power wheel 5 to rotate via the rotating shaft 61, thus propelling the frame 1 forward. When the child jumps upwards, the pressure applied to the saddle 3 disappears, and the rotating rod 21 moves upwards under the action of the reset member 4. At this time, the rotating rod 21 will not drive the drive wheel 621 to rotate, and the frame 1 continues to move forward under inertia until the child jumps to the highest point and falls, causing the saddle 3 to rotate downwards. This cycle repeats continuously. As the child jumps back and forth, the frame 1 moves forward, allowing the child to ride outdoors while also enhancing their enjoyment and physical activity. This combines a children's bicycle with entertainment equipment, enabling children to experience the fun of a seesaw and trampoline while going out. Furthermore, because the saddle 3 is located at the suspended end of the rotating rod 21, the child experiences a feeling of weightlessness during movement, similar to walking in space, thus enhancing the entertainment value.

[0092] It is understandable that when the rotating mechanism 2 is located on the side of the frame 1 opposite to the direction of travel, the construction of each component can be specifically set according to actual needs. For example, the handlebar 22 can be directly installed on the rotating rod 21 near the end of the frame 1.

[0093] It should be noted that the children's bouncy trampoline of this application can be designed in different sizes to suit the needs of children of different ages and meet the comfort requirements of children while playing. The overall height of the children's bouncy trampoline of this application is not specifically limited and can be designed according to the age and height of the applicable children.

[0094] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
