A toy car speed controller

[0001] This disclosure is based on and claims priority to Chinese Patent Application No. 2025206963073, filed on April 14, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of toy car controller technology, specifically a toy car speed controller. Background Technology

[0003] With technological advancements and improved living standards, a wide variety of toys have entered homes and become children's companions. Electric track toy cars, combining ingenious design and advanced technology, have become a popular choice for children. However, current track cars are limited in function, only able to move forward along a predetermined route and at a fixed speed, lacking in fun. After playing for a while, children easily lose interest. Furthermore, track toy cars are sold alongside toy tracks, making them relatively expensive. If children discard them after losing interest, the high cost can cause parents headaches and significantly reduce their desire to purchase them.

[0004] As we all know, in the field of children's intelligent toy cars, the accuracy and ease of operation of speed switching control directly affect the product's competitiveness in the market. Especially for track toy cars, if we want to attract children's interest in playing through competitions, setting up a speed switching structure on the remote control is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] To address the problems mentioned above, this application provides a toy car speed controller that enables speed switching by setting up a gear shifting component and a gear adjustment component, allowing children to experience the pleasure of different speeds while playing.

[0006] The following technical solution is adopted in this application:

[0007] A toy car speed controller includes a controller housing and a gear shifting assembly, a gear shifting adjustment assembly, and a gear shifting circuit board disposed within the controller housing, wherein:

[0008] The shift circuit board has at least two gear contacts with different speeds;

[0009] The gear shift assembly includes an operating lever that extends upward from the controller housing and a spring that engages with a gear shift contact. Shifting the operating lever causes the spring to connect with one of the gear shift contacts.

[0010] The shift adjustment assembly includes a push-pull rod extending upward from the controller housing and a stop connected to the push-pull rod; the gear shifting assembly also includes at least two gear abutments located at different positions; the push-pull rod is moved horizontally to cause the stop to abut against one of the gear abutments, and each gear contact corresponds to one gear abutment.

[0011] Furthermore, the gear shift assembly also includes a drive component and a shift moving component; a spring is disposed on the shift moving component, and an operating lever is disposed on the drive component; the drive component is connected to the shift moving component in a transmission manner, so that the spring on the shift moving component is connected to one of the gear position contacts.

[0012] Furthermore, the driving method of the driving component is rotational drive, and driving teeth are provided on the outer periphery of the lower part of the driving component. The shifting moving component includes a rack part that meshes with the driving teeth.

[0013] Furthermore, the gear shift contact part is provided on the gear shift moving part, and is distributed in a stepped manner along the moving direction of the gear shift moving part.

[0014] Furthermore, it also includes an elastic reset component located below the shifting component; one end of the elastic reset component abuts against the shifting component, and the other end abuts against the inner wall of the controller housing;

[0015] When the operating lever is driven by an external force to rotate the drive component and connect the spring to any gear position contact, the elastic reset component is in a compressed state; after the external force is released, the operating lever is reset under the action of the elastic reset component, causing the spring to disengage from any gear position contact.

[0016] Furthermore, a protrusion extending along its moving direction is provided below the shifting moving part, and one end of the elastic reset part is sleeved on the protrusion; a limiting groove is formed below the shifting moving part, and the elastic reset part is located in the limiting groove.

[0017] Furthermore, a guide bar is provided on the lower end face inside the controller housing, and a sliding groove matching the guide bar is provided on the shifting moving part.

[0018] Furthermore, the direction of the lever's movement is perpendicular to the direction of the push-pull lever's movement.

[0019] Furthermore, the controller housing is shaped like a steering wheel.

[0020] Furthermore, it also includes a trigger button connected to the shift circuit board, which protrudes from the upper surface of the controller housing.

[0021] Compared with the prior art, the beneficial effects of this application are as follows:

[0022] (1) The toy car speed controller of this application includes a gear shifting component, a gear shifting adjustment component, and a gear shifting circuit board. The gear shifting circuit board is provided with at least two gear contacts with different speeds. The gear shifting adjustment component includes a push-pull rod and a stop. In use, the push-pull rod can be moved to different positions by hand, so that the push-pull rod abuts against one of the gear abutment parts, restricting the position of the gear shifting component. Different positions of the gear shifting component result in different positions of the spring, that is, the spring contacts different gear contacts, thereby realizing the speed switching. The overall structure of this application is simple, and children can operate and switch speeds by themselves, greatly enhancing the fun.

[0023] (2) The toy car speed controller of this application has an elastic reset component below the moving part. When the operating lever drives the driving part to rotate under the action of external force, so that the spring is connected to any gear contact, the elastic reset component is in a compressed state. After the external force is released, the operating lever is reset under the action of the elastic reset component, so that the spring is disconnected from any gear contact. Thus, during the toy car's movement, the child needs to keep pushing the operating lever to keep the toy car moving forward within the predetermined speed, which improves the human-computer interaction and enhances the child's hands-on ability during play.

[0024] (3) The controller housing of the toy car speed controller of this application is shaped like a steering wheel, which perfectly simulates the steering wheel of a real car. When playing, it makes children feel as if they are driving a car, which greatly increases the attraction. Attached Figure Description

Detailed Implementation

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0035] The present invention will now be discussed in detail with reference to Figures 1 to 7 and specific embodiments.

[0036] As shown in Figures 1-7, this application provides a toy car speed controller, including a controller housing 1 and a gear shifting assembly 2, a gear shifting adjustment assembly 3, and a gear shifting circuit board 4 disposed within the controller housing 1. The gear shifting circuit board 4 is fixed within the controller housing 1 and has at least two gear contacts (not shown in the figures) with different speeds. Each gear contact has a different resistance. A spring 22 can achieve different resistance outputs by contacting different gear contacts, thereby achieving different speed outputs. The gear shifting assembly 2 includes an operating lever 21 extending upwards from the controller housing 1 and a spring 22 cooperating with the gear contacts. Manually moving the operating lever 21 changes its position, causing the spring 22 to move and connect with one of the gear contacts. Contact between the spring 22 and one gear contact achieves a specific resistance output; different resistance outputs result in different speeds.

[0037] The shift adjustment assembly 3 includes a push-pull rod 31 extending upward from the controller housing 1 and a stop 32 connected to the push-pull rod 31. The stop 32 is located inside the controller housing 1 and is used to limit the position of the spring 22, so that the spring 22 can only contact the gear position contact corresponding to the speed. The gear shifting assembly 2 also includes at least two gear position abutments 241 located at different positions. Horizontally moving the push-pull rod 31 causes the stop 32 to abut against one of the gear position abutments 241. Each gear position contact... A gear abutment part 241 is provided; it can be seen that the gear shifting component 2 and the gear shifting adjustment component 3 of this application are designed in a linkage manner. The movement position of the push-pull rod 31 limits the position where the operating lever 21 is shifted to the bottom. The position where the operating lever 21 is shifted to the bottom is different for different speeds. However, no matter which gear the speed is adjusted to, after the operating lever 21 is shifted to the bottom, one of the gear abutment parts 241 abuts against the stop member 32. At this time, the spring piece 22 is limited to a position and contacts the corresponding gear contact point.

[0038] For example, assuming the controller has three speed settings, there are three corresponding speed contact points: the first contact, the second contact, and the third contact. Similarly, the push-pull lever 31 also has three movement positions: the first speed setting 33, the second speed setting 34, and the third speed setting 35. When the push-pull lever 31 is moved to the first speed setting 33, the operating lever 21 is pushed all the way down, causing the stop member 32 to abut against the corresponding speed abutment part 241. At this time, the spring piece 22 can only contact the first contact point. When the push-pull lever 31 is moved to the second speed setting... When the lever 21 is moved to the third speed position 35, the stop 32 is stopped at the corresponding gear abutment 241, and the spring 22 can only contact the second contact point. When the push-pull lever 31 is moved to the third speed position 35, the lever 21 is moved to the third speed position 35, the stop 32 is stopped at the corresponding gear abutment 241, and the spring 22 can only contact the third contact point, thus realizing the speed switching of the toy car. It can be seen that this application does not limit the specific number of gears, and can set two, three, four, five, etc., to realize multiple speed adjustments.

[0039] The structure described in this application not only achieves precise switching speed, but also has a simple overall structure and is easy to operate. Users can adjust the switching speed according to their playing objectives, greatly enhancing the fun.

[0040] In some embodiments, referring to FIG3, the gear shift assembly 2 further includes a drive member 23 and a shift moving member 24; the spring 22 and the gear abutment part 241 are both disposed on the shift moving member 24, and the operating lever 21 is disposed on the drive member 23; the drive member 23 is connected to the shift moving member 24 in a transmission manner, so that the spring 22 on the shift moving member 24 contacts and connects with one of the gear contacts. When the user moves the operating lever 21, it drives the drive member 23 to move, and the drive member 23 drives the shift moving member 24 to move toward the stop member 32. When the gear abutment part 241 abuts with the stop member 32, the operating lever 21 moves to the bottom. At this time, the position of the shift moving member 24 and the shift circuit board 4 is relatively fixed, that is, the spring 22 on the shift moving member 24 contacts and connects with the corresponding gear contact, thereby realizing the output of the corresponding speed. This application utilizes the interaction between the gear stop 241 and the stop member 32 to ensure that the speed is switched to the correct position when the operating lever 21 can no longer be pushed. During play, there is no need to worry about accidental operation causing the toy car to deviate from the predetermined speed. In other words, the gear position can be determined by changing the position of the push-pull lever 31 before the track car is moved; subsequently, simply moving the operating lever 21 all the way down is sufficient.

[0041] In some embodiments, referring to FIG3, the driving method of the driving member 23 is rotational drive. The driving member 23 has driving teeth 231 on the outer periphery of its lower part. The shifting moving member 24 includes a rack portion 242 that meshes with the driving teeth 231. The rotational motion is converted into linear motion through the meshing of gears and racks. For example, the driving member 23 is a wheel-shaped structure with driving teeth 231 on its outer periphery. Moving the operating lever 21 can rotate the wheel-shaped structure, which in turn drives the shifting moving member 24 to perform linear motion. In this application, the circumferential length of the driving teeth 231 can be set according to the moving distance of the shifting moving member 24, without having to machine the driving teeth on the entire outer periphery. The portion of the controller housing 1 exposed is circumferentially smooth and has no machined driving teeth. The meshing of gears and racks not only realizes the conversion of motion but also reduces the number of parts.

[0042] Specifically, referring to Figures 2 and 3, the gear shift abutment 241 is provided on the gear shift moving member 24 and is distributed in a stepped manner along the moving direction of the gear shift moving member 24. The gear shift moving member 24 is provided with a stepped structure, and the number of steps is usually the same as the number of moving positions of the push-pull rod 31. The movement of the push-pull rod 31 causes the abutment 32 to abut against one of the steps, thereby realizing speed adjustment. For example, the push-pull lever 31 has three moving positions: first speed gear 33, second speed gear 34, and third speed gear 35. It also has three steps: first step 243, second step 244, and third step 245. When the push-pull lever 31 moves to the first speed gear 33, the stop 32 abuts against the first step 243. When the push-pull lever 31 moves to the second speed gear 34, the stop 32 abuts against the second step 244. When the push-pull lever 31 moves to the third speed gear 35, the stop 32 abuts against the third step 245. Of course, all of these abutments require the operating lever 21 to be fully turned.

[0043] In some embodiments, referring to Figure 2, an elastic reset member 5 is also included below the shifting movable member 24; one end of the elastic reset member 5 abuts against the shifting movable member 24, and the other end abuts against the inner wall of the controller housing 1; when the operating lever 21 drives the driving member 23 to rotate under the action of external force, causing the spring piece 22 to connect with any gear position contact, the elastic reset member 5 is in a compressed state; after the external force is released, the operating lever 21 resets under the action of the elastic reset member 5, causing the spring piece 22 to disengage from any gear position contact. That is to say, during play, if you want the toy car to move at a certain speed, the user needs to continuously apply external force to the operating lever 21. After the external force is released, the shifting movable member 24 and the operating lever 21 reset under the action of the elastic reset member 5, and the spring piece 22 also resets. The above structural design realizes human-computer interaction, enhances children's hands-on ability during play, and allows children to be fully immersed in controlling the toy car.

[0044] In some embodiments, referring to Figures 2 and 5, a protrusion 246 extending along its moving direction is provided below the shifting moving member 24, and one end of the elastic reset member 5 is sleeved on the protrusion 246; a limiting groove 247 is formed below the shifting moving member 24, and the elastic reset member 5 is located in the limiting groove 247. The protrusion 246 and the limiting groove 247 together restrict the position of the elastic reset member 5 and prevent the elastic reset member 5 from shifting.

[0045] Preferably, the elastic restoring element 5 in this application is a spring. The spring can be a commercially available ordinary spring, reducing manufacturing costs.

[0046] In some embodiments, referring to FIG2, a guide bar 11 extending along the moving direction of the shifting member 24 is provided on the lower end surface inside the controller housing 1, and a sliding groove 248 matching the guide bar 11 is provided on the shifting member 24. The cooperation between the guide bar 11 and the sliding groove 248 can ensure the accuracy of the moving direction of the shifting member 24 and prevent the spring piece 22 from deviating.

[0047] Specifically, referring to Figures 1 and 6, the direction of the operation lever 21 is perpendicular to the direction of the push-pull rod 31. The controller housing 1 has a strip groove 122 and a rotating groove 121. The push-pull rod 31 moves in the strip groove 122, and the operation lever 21 rotates in the rotating groove 121.

[0048] Specifically, in this embodiment, the controller housing 1 includes an upper housing 12 and a lower housing 13 that are interlocked. The upper housing 12 and the lower housing 13, when interlocked, form a steering wheel shape. The steering wheel shape perfectly simulates the steering wheel of a real car, giving children the feeling of driving a car while playing, greatly increasing the attraction and enjoyment.

[0049] Specifically, referring to Figures 3 and 6, a rotating groove 123 is provided inside the upper housing 12. The driving component 23 of this application has a wheel-shaped structure, and fixed shafts are provided on both sides of the wheel-shaped structure. The fixed shafts are rotatably connected in the rotating groove 123. For ease of installation, the rotating groove 123 is arched. At least one rotating groove 123 has a support member 131 fixed in the lower housing 13 below it. The support member 131 and the rotating groove 123 together confine the fixed shaft in the rotating groove 123.

[0050] Specifically, referring to Figures 1 and 2, it also includes a trigger button 6 connected to the shift circuit board 4. The trigger button 6 protrudes from the upper surface of the controller housing 1. After the speed gear is adjusted, pressing the trigger button 6 will control the toy car to travel at the predetermined speed.

[0051] Specifically, referring to Figure 7, the bottom of the controller housing 1 is also provided with a battery mounting slot 132. The battery mounting slot 132 is located below the shift circuit board 4. The battery mounting slot 132 is used to install a battery, which supplies power to the shift circuit board 4.

[0052] The present application has been further described above with reference to specific embodiments. However, it should be understood that the specific descriptions herein should not be construed as limiting the substance and scope of the present application. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present application.
