Technical Field
[0001] This utility model relates to the field of children's toy technology, specifically to a children's toy car that launches sequentially. Background Technology
[0002] Currently, toy cars are a major category of children's toys, bringing great joy to children's growth. Some larger electric toy cars are loved by many parents and children because of their impressive and exquisite appearance and ability to move automatically.
[0003] In the prior art, a shock-resistant plastic toy car disclosed in patent publication number "CN215084842U" includes a toy car body, a fixed rod connected to one side of the toy car body, a second buffer plate connected to one side of a first spring, a buffer groove connected inside the connecting plate, a buffer spring connected to one side of a buffer block, a fixed block connected to the surface of the buffer rod, a connecting block connected to one side of the surface of the first buffer plate, a second spring under a T-shaped sliding plate, and a limit washer connected to the surface of the T-shaped sliding plate. By setting the second buffer plate and the first spring, the front and rear of the toy car body can be protected, and it will not be damaged when it is impacted or dropped on the ground. By setting the first buffer plate, buffer rod, buffer block, and buffer spring, the sides of the toy car body are protected, effectively dissipating the impact force and allowing it to recover, preventing damage to the buffer plate. Therefore, the parts are located inside the toy car body, and the external appearance is that of a complete toy car.
[0004] However, existing technologies still have significant shortcomings. Traditional inertial toy cars have limited gameplay and poor interactivity, and can easily become boring after prolonged use. They can usually only be used to move the car for entertainment, and cannot be combined with other small toy cars for entertainment. When the inertial toy car is being pushed, it is impossible to launch the loaded small toy cars in sequence. Utility Model Content
[0005] The purpose of this invention is to provide a children's toy car that launches sequentially, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a children's toy car with sequential launch capability, comprising a car shell, with front wheels and rear wheels respectively provided on the bottom surface of the car shell, a launch channel opened at the front opening of the car shell, an embedded shell installed inside the car shell, a launch mechanism connected inside the car shell, the launch mechanism comprising a launch platform, a transmission rod provided at the bottom of the launch platform, a transmission gear fixed on the surface of the transmission rod, a connecting gear provided near the transmission gear, a connecting column fixed at the center of the connecting gear, a half gear connected to one end of the connecting column, a transmission cavity opened on the side of the launch platform, a toothed groove arrayed on the top surface inside the transmission cavity, and hooks provided at the front end of the launch platform and at corresponding positions inside the car shell.
[0007] As can be seen, in the above technical solution, the rotation of the rear wheel drives the transmission gear set, which in turn drives the half gear to mesh with the tooth groove to achieve precise linear movement of the launch platform. Combined with the tension spring energy storage mechanism, a reliable launch power source is formed. The special structure of the half gear ensures that the launch platform automatically disengages when it moves to the limit position, and the trolley is ejected at high speed under the action of the tension spring rebound force.
[0008] Preferably, a transmission rod is connected at the center of the rear wheel, and the surfaces of the transmission gear and the connecting gear mesh with each other, and the connecting gear is connected to the vehicle body.
[0009] As can be seen, in the above technical solution, manually pushing the car body forward causes the rear wheels to rotate, and under the action of the transmission rod, the transmission gear can rotate and the meshing connecting gear can move.
[0010] Preferably, the half gear is located inside the transmission cavity, and the teeth on the surface of the half gear mesh with the tooth grooves, and the half gear has a 180° half-tooth structure.
[0011] As can be seen, in the above technical solution, when the launch pad moves to the limit position, the toothless plane of the half gear rotates to a position opposite to the tooth groove, and the two completely disengage.
[0012] Preferably, the embedded shell is located near the back of the interior of the vehicle body, the top of the embedded shell has an embedded end, and the embedded end is located outside the vehicle body. An inlet movable plate is axially connected to the back of the embedded shell.
[0013] As can be seen, in the above technical solution, the trolley to be launched can be inserted sequentially from the embedded end, and the entrance movable plate can be rotated to open or close. When opened, it is convenient to insert the trolley, and when closed, it can prevent the trolley from detaching from the entrance end.
[0014] Preferably, a guide plate is fixed near the embedded end, and the guide plate is installed at an angle from high to low.
[0015] As can be seen, in the above technical solution, the guide plate can guide the trolley after it is placed in, so that the trolley can smoothly slide down to the specified position.
[0016] Preferably, the front end of the embedded shell is connected to a baffle plate, and a launch outlet is provided between the baffle plate and the launch pad.
[0017] As can be seen, in the above technical solution, the blocking plate can block all vehicles except the first one that needs to be launched.
[0018] Preferably, the launch platform has a stepped structure and is slidably connected to the interior of the vehicle body.
[0019] As can be seen, in the above technical solution, the stepped structure can form an inclined bearing surface when the trolley slides down, enabling it to be accurately positioned.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. The use of an embedded inclined guide plate and a baffle plate ensures that the trolleys are arranged in strict order. The inclined design of the guide plate allows the inserted trolleys to slide automatically to the launch position, while the baffle plate effectively prevents the subsequent trolleys from piling up and interfering with the launch order. The flip-up inlet movable plate not only facilitates the loading of the trolleys but also reliably seals part of the embedded end, solving the problem of subsequent trolleys accidentally falling off during launch.
[0022] 2. The rotation of the rear wheels drives the transmission gear set, which in turn drives the half gear to mesh with the tooth groove to achieve precise linear movement of the launch platform. Together with the tension spring energy storage mechanism, it forms a reliable launch power source. The special structure of the half gear ensures that the launch platform automatically disengages when it moves to the limit position, and the trolley is launched at high speed under the action of the tension spring rebound force.
[0023] 3. The stepped launch platform enables a smooth transition of the toy car from an inclined, ready-to-launch state to a horizontal launch state, ensuring the accuracy of the launch trajectory. The entire launch process only requires a simple push of the car body to automatically complete the complete sequence of charging and releasing actions. Multiple cars can be launched in sequence without complicated operations. The integrated mechanical structure greatly improves the reliability and durability of the toy and provides children with an intuitive and fun physical interactive experience.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-6 This utility model provides a technical solution:
[0033] Example 1: A children's toy car for sequential launch: It includes a car shell 1, with front wheels 11 and rear wheels 12 respectively located on the bottom surface of the car shell 1. A launch channel 2 is opened at the front opening of the car shell 1. An insert shell 3 is installed inside the car shell 1, located near the back of the inside of the car shell 1. An insert end 31 is opened at the top of the insert shell 3, and the insert end 31 is located outside the car shell 1. The car shell 1 is the outer shell of the toy car, including the front wheels 11 and rear wheels 12. Cars to be launched sequentially can be inserted one by one from the rear of the car shell 1 through the exposed insert end 31. An inlet movable plate 32 is axled to the back of the insert shell 3, near the insert end. A guide plate 34 is fixed at position 31, and the guide plate 34 is installed at an angle from high to low. The trolley enters the embedded shell 3 and slides down along the guide plate 34 inside to the launch outlet 33. The first end of the embedded shell 3 is connected to a baffle plate 35, and a launch outlet 33 is provided between the baffle plate 35 and the launch platform 41. It should be noted that the channel inside the embedded shell 3 cannot support the trolleys to enter side by side. The trolleys are only allowed to enter one by one in sequence. The guide plate 34 is an inclined guide plate 34, and the inclination direction is from high to low. The inclined surface of the guide plate 34 allows the trolleys to enter the embedded shell 3 smoothly in sequence.
[0034] The first vehicle to be launched is located at the launch outlet 33 below the blocking plate 35. The blocking plate 35 can block subsequent vehicles, preventing them from piling up at the launch outlet 33. The inlet movable plate 32 is pivotally connected to the back of the embedded shell 3 and can be flipped up to engage with the interface corresponding to the embedded shell 3 at the top, thus partially blocking the embedded end 31. When placing the vehicle, the inlet movable plate 32 can be flipped downwards, increasing the opening size of the embedded end 31, making it easier for the player to place the vehicle. At the same time, closing the inlet movable plate 32 can prevent subsequent vehicles from falling out of the embedded end 31 due to the force after the first vehicle is launched. The launch mechanism 4 is connected inside the vehicle shell 1.
[0035] The launching mechanism 4 includes a launching platform 41, which has a stepped structure and is slidably connected to the interior of the vehicle body 1. A transmission rod 43 is provided at the bottom of the launching platform 41, and a transmission gear 44 is fixed on the surface of the transmission rod 43. Hooks 42 are provided at the front end of the launching platform 41 and at corresponding positions inside the vehicle body 1. The launching mechanism 4 mainly drives the launching platform 41 to move linearly inside the vehicle body 1 through multiple gears. Since hooks 42 are provided at the front end of the launching platform 41 and on the vehicle body 1, the hooks 42 are mainly used to install tension springs. After connecting the two ends of the tension spring to the hooks 42, the tension spring can be stretched when the launching platform 41 moves forward. The player only needs to manually push the vehicle body 1 forward, at which time the rear wheel 12 rotates, driving the transmission gear 44 on the surface of the transmission rod 43 to rotate.
[0036] A connecting gear 45 is located near the transmission gear 44. A transmission rod 43 is connected to the center of the rear wheel 12. The surfaces of the transmission gear 44 and the connecting gear 45 mesh with each other. The connecting gear 45 is connected to the vehicle body 1. A connecting post 46 is fixed at the center of the connecting gear 45. A half gear 47 is connected to one end of the connecting post 46. A transmission cavity 48 is opened on the side of the launch platform 41. The top surface of the transmission cavity 48 is arrayed with tooth grooves 49. The half gear 47 is located in the transmission cavity 48, and the teeth on the surface of the half gear 47 mesh with the tooth grooves 49. The transmission gear 44, connecting gear 45, and... Under the action of the half gear 47 and the toothed groove 49 on the launch shell, the rear wheel 12 rotates, causing the launch platform 41 to move backward, thereby stretching the tension spring. When the launch platform 41 moves to its farthest position, the half gear 47 is located at the beginning of the toothed groove 49. Since the half gear 47 is half-toothed, the position where there are no meshing teeth is located at the beginning of the toothed groove 49. Under the rebound action of the tension spring, the launch platform is released, thereby launching the car. By operating in sequence, the cars ready for launch can be launched. Pushing the car shell 1, the internal launch mechanism 4 automatically releases the first toy car. The vehicle is pushed again, releasing the second vehicle, and so on, thus achieving sequential launch. The half-gear 47 has a 180° half-tooth structure. It's worth noting that the launch platform 41 has a stepped shape. When the first vehicle slides down the guide plate 34 until it reaches the stepped position on the launch platform 41, the first vehicle is tilted. After the launch platform 41 moves backward, the first vehicle gradually moves away from the blocking plate 35, returning to its normal position and aligned with the launch channel 2. After launch, the moving platform uses the spring's rebound force to push the vehicle out from the exit on the front of the vehicle body 1. The connecting gear... The connecting post 46 is connected to the half gear 47. When the transmission gear 44 rotates, it can cause the connecting gear 45 to move, thereby driving the connecting rod and the half gear 47 to rotate. When the launch platform 41 moves to the limit position, the toothless plane of the half gear 47 rotates to the position opposite to the tooth groove 49, and the two completely disengage. At this time, the spring return force acts on the linear motion of the launch platform 41, and the tooth groove 49 moves axially. However, because there is no gear meshing, it cannot push the half gear 47 to rotate. After the engagement, the half gear 47, the connecting gear 45, and the transmission gear 44 are all in a free spinning state. Whether the wheel rotates or not has no effect on the launch platform 41.
[0037] Working principle: When the player pushes the vehicle body 1 forward, the rear wheel 12 rotates, driving the transmission gear 44 on the transmission rod 43 to rotate. This, in turn, drives the half gear 47 to rotate via the meshing connecting gear 45. The meshing of the half gear 47 with the tooth groove 49 of the launch platform 41 causes the launch platform 41 to move backward in a straight line, stretching the tension spring to store energy. When the launch platform 41 reaches its limit position, the toothless section of the half gear 47 rotates to the position where it disengages from the tooth groove 49. At this point, the spring's rebound force pushes the launch platform 41 forward at high speed, ejecting the vehicle located at the launch exit 33. Due to the disengagement of the half gear 47 and the one-way transmission characteristics of the gear set, the rebound force cannot be transmitted to the transmission system in the reverse direction, ensuring that the car body 1 will not move backward and the rear wheel 12 will not reverse. After the launch is completed, the subsequent cars will automatically slide to the launch position under the action of the inclined guide plate 34. The blocking plate 35 prevents the cars from piling up, and the entrance movable plate 32 remains closed to prevent the cars from falling accidentally. Repeatedly pushing the car body 1 can realize the continuous launch of the remaining cars. The whole process realizes the one-button sequential launch function through ingenious mechanical linkage, ensuring the reliability and continuity of the launch.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
