Description

Technical Field

[0001] This utility model belongs to the field of children's toy technology, and more specifically, it relates to a power-accumulating toy car. Background Technology

[0002] Pump-action toy cars, also known as pullback toy cars, require only pressing the car body and dragging it backward a short distance to operate. After releasing the handle, the toy car can travel a longer distance via a pullback gear structure (spring structure or rubber band structure). Existing pump-action toy cars generally consist of a chassis, tires, a pump box, and a car shell.

[0003] Existing application number: CN201620782072.0. This utility model relates to the field of pullback toys, and more particularly to a pullback toy car with dual energy storage units. It includes a car shell, chassis, front wheels, rear wheels, and a pullback drive mechanism. The two rear wheels are connected via a first rotating shaft, and the pullback drive mechanism is driven by the first rotating shaft. The front and rear wheels are rotatably mounted on the chassis via the first and second rotating shafts, respectively. The car shell is mounted on the chassis. The first rotating shaft is fitted with a first gear and a second gear. The pullback drive mechanism includes a first energy storage unit driven by the first gear, a second energy storage unit driven by the second gear, and a housing. This utility model has a simple structure, does not require a power source, and allows manual replenishment of energy to the toy car. The pullback drive mechanism has two energy storage units; the potential energy stored in the two units is superimposed, effectively increasing the potential energy stored in the toy car and converting more potential energy into kinetic energy, enabling the toy car to travel a greater distance.

[0004] Based on the above, in order to add more fun, many power-up cars are designed with interchangeable shells. Most of these shells use flexible plastic clips to achieve an interference fit connection, or are fixed with screws. However, plastic clips are easily damaged and broken during disassembly and assembly, which not only increases the difficulty for children to operate, but may also bring the risk of scratches. Although the screw connection method is stable, it requires the use of additional tools such as screwdrivers for disassembly and assembly, which is quite cumbersome for children. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a power-operated toy car. To add more fun, many power-operated cars are designed with interchangeable shells. These shells mostly use flexible plastic clips for interference fit or are fixed with screws. However, plastic clips are easily damaged or broken during assembly and disassembly, increasing the difficulty for children to operate and potentially causing scratches. While screw connections are secure, they require additional tools such as screwdrivers for assembly and disassembly, which is quite cumbersome for children.

[0006] The purpose and effect of this utility model of a power-accumulating toy car are achieved by the following specific technical means:

[0007] A power-operated toy car, including a chassis;

[0008] A power storage tank, which is fixedly connected to the chassis;

[0020] Furthermore, the fixing and separating assembly also includes:

[0021] The connecting box consists of two pieces, which are separately and fixedly connected to the bottom of the vehicle body.

[0022] Two connecting slots are provided, and the two connecting slots are respectively provided on the top of the two connecting boxes.

[0023] Furthermore, the fixing and separating assembly also includes:

[0024] A limiting ratchet is coaxially and fixedly connected to the bottom of the first drive shaft;

[0025] A limiting pawl is rotatably connected inside the transmission box, and the limiting pawl meshes with a limiting ratchet.

[0026] Furthermore, the fixing and separating assembly also includes:

Then, move the car body upward to separate it from the chassis. Once the new car body is attached to the chassis, push the front end of the limiting pawl forward to re-insert the two sliding parts into the two connecting slots. The operation is simple and easy, and children can operate it independently.

[0034] Secondly, when attaching the new body shell to the chassis, the positioning pins and positioning holes can be used to initially position the new body shell. This allows for quick alignment of the new body shell and chassis during installation, making the subsequent insertion of the two sliding parts into the two connecting slots smoother.

[0035] This invention allows the car body to be quickly separated from the chassis by pulling the connecting rod.

Detailed Implementation

[0044] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0045] Example 1:

[0046] As attached Figure 1 To be continued Figure 6 As shown:

[0047] This utility model provides a power-accumulating toy car, including a chassis 1;

[0048] Energy storage box 2 is fixedly connected to chassis 1;

[0049] Car body 3, the car body 3 is set on the chassis 1;

[0050] Transmission box 4 is fixedly connected to the bottom of chassis 1;

[0051] Two fixing boxes 5 are provided, and the two fixing boxes 5 are separately and fixedly connected to the chassis 1.

[0052] Sliding component 6, two sliding components 6 are provided, and the two sliding components 6 are slidably connected inside the two fixed boxes 5 respectively, and the bottom of the two sliding components 6 are slidably connected to the chassis 1 respectively;

[0053] Two connecting rods 601 are provided, and the two connecting rods 601 are respectively fixedly connected to the lower ends of the two sliding parts 6;

[0054] The fixing and separating components are located inside the transmission box 4 and the two fixing boxes 5.

[0055] The fixing and separating components include:

[0056] Two transmission racks 602 are provided, and the two transmission racks 602 are respectively fixedly connected to the inner side of two connecting rods 601.

[0057] The first drive shaft 7 is rotatably connected inside the transmission box 4;

[0058] The transmission gear 701 is coaxially fixed to the top of the first transmission shaft 7. The transmission gear 701 meshes with two transmission racks 602 respectively. The effect is that pulling any one of the connecting rods 601 inward can drive the corresponding transmission rack 602 and sliding member 6 to move. At the same time, under the action of the gear and rack transmission mechanism formed by the meshing of the transmission gear 701 and the two transmission racks 602 respectively, the other transmission rack 602 and sliding member 6 will move in the opposite direction at the same time.

[0059] The fixing and separating components also include:

[0060] Connecting box 9, two connecting boxes 9 are provided, and the two connecting boxes 9 are fixedly connected to the bottom of the car body 3 separately;

[0061] There are two connecting slots 901. The two connecting slots 901 are respectively opened on the top of the two connecting boxes 9. The function is that when the two sliding parts 6 move inward at the same time, they will separate from the two connecting slots 901 respectively. Then, the car body 3 can be separated from the chassis 1 by moving the car body 3 upward.

[0062] The fixing and separating components also include:

[0063] A limiting ratchet 702 is coaxially and fixedly connected to the bottom of the first drive shaft 7.

[0064] The limiting pawl 8 is rotatably connected inside the transmission box 4. The limiting pawl 8 meshes with the limiting ratchet 702. The effect is that under the action of the ratchet and pawl transmission mechanism formed by the meshing of the limiting pawl 8 and the limiting ratchet 702, the first transmission shaft 7 can only rotate in one direction. This allows the two sliding parts 6 to move inward at the same time and remain in their current position, making it convenient for children to perform subsequent operations.

[0065] The fixing and separating components also include:

[0066] Connecting spring 801, two sets of connecting spring 801 are provided, and two pieces of connecting spring 801 are provided in each set. The outer ends of the two sets of connecting spring 801 are respectively fixedly connected to the inner side of the two sliding pieces 6, and the inner ends of the two connecting spring 801 are respectively fixedly connected to the inside of the two fixed boxes 5.

[0067] The return spring 10 is fixedly connected at its right end to the front end of the limiting pawl 8 and at its left end to the inside of the transmission box 4. Its function is to push the front end of the limiting pawl 8 forward so that the limiting pawl 8 disengages from the limiting ratchet 702, thereby releasing the restriction on the first transmission shaft 7. Then, under the rebound action of the two sets of connecting springs 801, the two sliding parts 6 move outward at the same time and are inserted into the two connecting slots 901 respectively. The front end of the limiting pawl 8 is released, and under the rebound action of the connecting springs 801, the limiting pawl 8 and the limiting ratchet 702 re-engage.

[0068] The specific usage and function of this embodiment are as follows:

[0069] When the body shell 3 needs to be replaced, pulling any connecting rod 601 inward will move the corresponding transmission rack 602 and sliding member 6. Simultaneously, under the action of the gear and rack transmission mechanism formed by the meshing of the transmission gear 701 and the two transmission racks 602, the other transmission rack 602 and sliding member 6 will move in opposite directions. The simultaneous inward movement of the two sliding members 6 will cause them to disengage from the two connecting slots 901. Then, moving the body shell 3 upward will separate it from the chassis 1. Furthermore, under the action of the ratchet and pawl transmission mechanism formed by the meshing of the limiting pawl 8 and the limiting ratchet 702, the first... The drive shaft 7 can only rotate in one direction, so that the two sliding parts 6 will remain in their current position after moving inwards simultaneously. Then, the new car body 3 is attached to the chassis 1. Then, the front end of the limiting pawl 8 is pushed forward, which disengages the limiting pawl 8 from the limiting ratchet 702, releasing the restriction on the first drive shaft 7. Under the rebound action of the two sets of connecting springs 801, the two sliding parts 6 move outwards simultaneously and are inserted into the two connecting slots 901 respectively. The front end of the limiting pawl 8 is released, and under the rebound action of the connecting springs 801, the limiting pawl 8 and the limiting ratchet 702 re-engage, making it convenient for the next use.

[0070] Example 2:

[0071] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes a quick positioning component, which is located inside the chassis 1.

[0072] The rapid positioning component includes:

[0073] Positioning holes 101 are provided in two sets, with two holes in each set, and the two sets of positioning holes 101 are distributed inside the chassis 1.

[0074] Positioning posts 902 are provided in two sets, with two pieces in each set. The two sets of positioning posts 902 are fixedly connected to the bottom of the two connecting boxes 9 respectively.

[0075] The specific usage and function of this embodiment are as follows:

[0076] When attaching the new body shell 3 to the chassis 1, the positioning pin 902 can be inserted into the positioning hole 101 first to preliminarily position the new body shell 3. During installation, the new body shell 3 and chassis 1 can be quickly aligned, making the subsequent insertion of the two sliding parts 6 into the two connecting slots 901 smoother.
