Resetting member, resetting structure and remote control deformable vehicle

Abstract

The application provides a reset member, a reset structure and a remote control transformable vehicle. The reset member comprises a fixed part and a body fixed to the surface of the fixed part. The outer contour of the body is wavy. A through groove is arranged on the central axis of the body. The body on either side of the groove can be elastically deformed into the groove under the action of force. The reset structure can be constructed based on the reset member, and the reset structure can be used on the remote control transformable vehicle. Since the middle part of the reset member is hollowed out, greater elastic deformation can be generated, and then the matching gap between the reset member and the cam group can be reduced to about 0.1. During the transformation of the remote control vehicle, when interference occurs, the reset member can avoid the problem of jamming between the reset member and the cam group due to elastic deformation. The problem that the existing remote control transformable vehicle is easy to deviate during straight driving is solved.

Description

Technical Field

[0001] The present invention relates to the technical field of remote-controlled deformable vehicles, and in particular to a reset component, a reset structure and a remote-controlled deformable vehicle. Background Art

[0002] A remote-controlled transforming car is a toy car capable of transforming between its normal, transformed, left-turning, and right-turning configurations. Its power output typically consists of two components: a drive gearbox and a transforming gearbox. The drive gearbox drives the wheels, while the transforming gearbox primarily allows the car to transform between these configurations.

[0003] The gearbox consists of a gearbox, a cam assembly, and a reset element. The gearbox drives the cam assembly via a drive shaft, which in turn drives the front and rear components to rotate around the reset element. To prevent interference between the cam assembly and the reset element during use, a certain gap must be left between the cam assembly and the reset element to allow the cam assembly to rotate freely within the gap. This can cause the vehicle to not travel in a straight line during normal driving (it is prone to deviation when traveling in a straight line).

[0004] Therefore, how to improve the straight-line driving of remote-controlled deformable cars is an urgent problem to be solved. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a reset member, a reset structure and a remote-controlled deformable vehicle, aiming to solve the problem that the existing remote-controlled deformable vehicles are prone to deviation when driving in a straight line.

[0006] A reset member, comprising: a fixing portion and a body fixed to the surface of the fixing portion; the outer contour of the body is wavy, a through groove is arranged on the central axis of the body, and the body located on either side of the groove can undergo elastic deformation into the groove under the action of force; both ends of the fixing portion are provided with L-shaped clamping portions for clamping.

[0007] The above-mentioned reset member is configured by arranging a through groove in the middle of the main body to accommodate the elastic deformation of the main body due to force. Since the groove can accommodate the elastic deformation of the main body (producing a larger elastic deformation), the reset member can be used in an environment where the size changes due to elastic deformation after being subjected to force and the original size is restored when the force is removed, thereby broadening the scope of use of the reset member.

[0008] Optionally, in the reset member, the body includes a base and a concave extension formed by extending outward from the base, and the base is fixed to the surface of the fixing portion.

[0009] Optionally, in the reset member, the width of the groove is 2-3 mm.

[0010] Optionally, the reset member is made of plastic.

[0011] Based on the same inventive concept, the present invention provides a reset structure, including the reset member as described above, which further includes: a cam group and a deformation component; the deformation component includes a deformation gear box and a transmission shaft, and the cam group is connected to the deformation gear box through the transmission shaft; the reset member is used to reset the cam group after rotation.

[0012] The reset structure described above can accommodate the elastic deformation of the reset member body through the groove on the reset member, and can reduce the reserved gap between the reset member and the cam group.

[0013] Optionally, the reset structure, wherein the cam group includes: a cam accessory and a cam; the cam accessory includes an accessory body, the accessory body includes an arc-shaped groove and a notch connected to the arc-shaped groove; the arc-shaped groove is adapted to the cam, and a part of the body is located in the notch.

[0014] Optionally, the reset structure, wherein the deformable gear box includes: an outer shell, a head connected to the outer shell, a gear set arranged on one side of the head, and a motor providing power for the rotation of the gear set; the transmission shaft passes through the head and engages with the gear set.

[0015] Based on the same inventive concept, the present invention also provides a remote-controlled transformable vehicle, comprising a vehicle head, a vehicle body, and a vehicle tail, wherein the vehicle further comprises a first reset structure and a second reset structure;

[0016] The first reset structure is the reset structure described above; the second reset structure includes a second reset member and a second cam assembly;

[0017] The deformation assembly and the reset member in the first reset structure are arranged at one end of the vehicle body portion, the rear portion of the vehicle includes a first end portion for connecting with the vehicle body portion, and the cam group is arranged on the first end portion; the second reset member is arranged at the other end of the vehicle body portion, the front portion of the vehicle includes a second end portion for connecting with the vehicle body portion, and the second cam group is arranged on the second end portion.

[0018] The remote-controlled transforming vehicle described above utilizes a reset member with a hollowed-out center portion, which allows for greater elastic deformation when encountering interference. When the interference disappears, the reset member instantly returns to its original shape due to this elastic deformation, maintaining an effective clearance with the cam attachment. This allows for a very small clearance between the reset member and the cam attachment, thus resolving the issue of the remote-controlled transforming vehicle being prone to deviation (inability to properly follow a straight line) when traveling in a straight line due to an excessive clearance between the reset member and the cam attachment.

[0019] Optionally, in the remote-controlled transforming car, the cam group in the first reset structure includes: a cam accessory and a cam, and the cam is fixedly connected to one end of the transmission shaft; the second cam group includes: a second cam and a second cam accessory, and the second cam is fixedly connected to the other end of the transmission shaft.

[0020] Optionally, in the remote-controlled transforming car, the cam accessory and the second cam accessory have the same structure, both including an accessory body, and the accessory body includes an arc-shaped groove and a notch connected to the arc-shaped groove.

[0032] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] When the existing reset parts are subjected to external forces, such as being squeezed on the left and right sides, they cannot produce elastic deformation well. This results in a large gap being left between them and other parts during use (to avoid interference), and they are not suitable for scenarios where a smaller gap needs to be reserved.

[0035] Exemplary technology, the reset part is applied to the remote control transforming car. The existing remote control transforming car can realize the normal form, the deformed form, the left turn form and the right turn form and the mutual conversion.

[0036] Specifically, the power output of the remote control transforming car is composed of a driving gearbox and a transforming gearbox, wherein the transforming gearbox can realize the transformation of the car between the above forms. The working principle of the transforming gearbox is that the transforming gearbox drives the cam group to rotate through the transmission shaft, and the cam group drives the front 2 and rear 3 of the car to rotate around the reset member; when the cam group rotates 50 degrees clockwise around the reset member from the normal state and maintains 50 degrees, the front and rear of the car will form a 50-degree angle with the body (because the front and rear of the car are rigidly connected to the cam group). This state is a left turn. Figure 7 As shown; when the cam assembly rotates 50 degrees counterclockwise around the reset member from the normal state and maintains 50 degrees, the front and rear of the vehicle form an angle of 50 degrees with the body of the vehicle. This state is a right turn. Figure 8 As shown; when the cam assembly rotates 180 degrees clockwise around the reset member from the normal state and maintains 180 degrees, the front and rear assemblies are at an angle of 20 degrees to the body. This state is deformed as shown Figure 6 As shown; when the cam group rotates 180 degrees counterclockwise around the reset member from the deformed state and maintains 180 degrees, this is the deformed reset state. Figure 5As shown in the figure, the disadvantage of this structure is that the clearance between the reset member and the cam group is too large, about 2mm. As a result, the cam group can rotate freely in the gap, which further drives the front and rear of the car to rotate freely, resulting in the car being unable to travel in a straight line. If there is no gap between the reset member and the cam group, when the car is deformed, when the cam group rotates to 90 degrees, it will interfere with the reset member, as shown in the figure. Figure 9 As shown; the result of interference is that the deformation gear box is stuck and cannot be deformed, or the current of the gear box is large, resulting in short battery life, or even the reset part is twisted off.

[0037] Based on this, the present invention provides a solution that can solve the above technical problems, and its details will be described in subsequent embodiments.

[0038] See also Figures 1 to 2 As shown in the figure, the reset member 10 includes a main body 100 and a fixing portion 110. The outer contour 101 of the main body 100 is wavy, and the main body 100 is connected to the fixing portion 110. A through groove 102 is provided in the middle of the main body 100. The main body 100 located on either side of the groove 102 can undergo elastic deformation into the groove 102 under the action of force.

[0039] In this embodiment, both ends of the fixing portion 110 are provided with L-shaped clamping portions 111 for clamping. The reset member can be fixed to other components by the two L-shaped clamping portions. It is easy to understand that other components are provided with structures adapted thereto. The body 100 includes a base 103 and a concave extension portion 104 formed by the base 103 extending outward (in a direction perpendicular to the fixing portion 110), and the base 103 is connected to the fixing portion 110. It is easy to understand that the groove 102 is opened in the middle part of the extension portion 104, and of course the groove can be extended to the fixing portion 110 as needed.

[0040] In one implementation of this embodiment, the material of the restoration member may be a plastic material, such as PC / ABS, PA6, PA66, POM, PP+fiber, etc. The width of the groove 102 may be 2-3 mm.

[0041] Based on the same inventive concept, the present invention also provides a reset structure, such as Figures 3 and 4 As shown, the reset member 10 includes a cam assembly 20 and a deformation assembly 30. The deformation assembly 30 includes a deformation gear box 31 and a transmission shaft 32. The cam assembly 20 is connected to the deformation gear box 31 via the transmission shaft 32. The reset member 10 is used to reset the cam assembly 20 after rotation. At the same time, the elastic deformation of the reset member can also help reset the deformation gear box.

[0042] In this embodiment, combined with Figure 10The cam assembly 20 includes a cam 200 and a cam attachment 210 for use with the cam 200. The cam attachment 210 includes an attachment body 211. The attachment body 211 includes an arcuate groove 212 and a V-shaped notch 213 connected to the arcuate groove 212. The arcuate groove 212 is adapted to fit the cam 200, and the extended portion of the body 100 (the portion where the outer contour contracts inward) is disposed within the V-shaped notch 213. It is easy to understand that the groove 212 can be disposed in the middle portion of the attachment body 211, with the bottom of the V-shaped notch connected to the groove 212, and the V-shaped notch 213 communicating with the groove 212.

[0043] In one implementation of this embodiment, the deformation gear box 31 includes: an outer shell 310, a head 311 connected to the outer shell 310, a gear set 312 arranged on one side of the head 311, and a motor 313 that provides power to the gear set 312; the transmission shaft 32 passes through the head 311 and engages with the gear set 312. It is easy to understand that the head 311 is adapted to the outer shell 310, and the gear set 312 is arranged inside the outer shell 310. One end of the transmission shaft 32 is connected to the cam 200, and the other end passes through the head 311 and extends deep into the inner part of the outer shell 310. A gear that engages with the gear set 312 is provided on the transmission shaft. The motor 313 drives the gear set 312 to rotate, and the gear set 312 drives the transmission shaft 32 to realize the rotation of the cam group 20.

[0044] Based on the same inventive concept, the present invention also provides a remote control deformable car, such as Figure 5 、 Figure 11As shown, the vehicle comprises a body portion 1, a front portion 2 and a rear portion 3 respectively connected to the body portion 1, a first reset structure 4, and a second reset structure 5. The front portion 2 includes a wheel assembly and an end portion for connecting to the body portion 1, with a cam assembly 20 disposed on the end portion. The rear portion 3 includes a wheel assembly and an end portion for connecting to the body portion 1, with a second cam assembly 201 disposed on the end portion. A reset member 10 and a deformation assembly 30 are disposed on the end of the body portion 1 near the rear portion 3, and a second reset member 11 is disposed on the end of the body portion 1 near the front portion 2. It should be noted that the cam assembly and the second cam assembly have the same structural composition, with one being disposed on the front portion 2 and the other on the rear portion 3. For ease of distinction, one is defined as the cam assembly and the other as the second cam assembly. As will be readily understood, the cam assembly comprises a cam and a cam attachment. The cam attachment comprises an attachment body, which includes an arcuate groove and a notch connected to the arcuate groove. The transmission shaft 32 in the deformation assembly 30 is connected to the cam in the cam assembly, and the reset member cooperates with the cam group to connect the vehicle head 2, the vehicle tail 3 and the vehicle body 1 together to form a remote control deformation vehicle.

[0045] In this embodiment, since the middle of the reset member is provided with a through groove, the gap between the reset member and the cam attachment can be reduced to only about 0.1 mm when the reset member cooperates with the cam attachment. When the remote control deformable car is deformed, the cam group rotates to drive the front and rear of the car to rotate. When it rotates to 55 degrees, the reset member and the cam attachment begin to interfere with each other. Figure 10 As shown in the figure, the cam group continues to rotate, and the interference between the reset member and the cam attachment becomes greater and greater until the cam group rotates 90 degrees and the interference disappears. During the interference process, the middle part of the reset member is hollowed out, resulting in greater elastic deformation. When the interference disappears, the reset member immediately recovers its original shape due to the elastic deformation and maintains an effective fitting clearance with the cam attachment.

[0046] In summary, the present invention provides a reset member, a reset structure, and a remote-controlled deformable vehicle. The reset member comprises: a fixing portion and a body fixed to the surface of the fixing portion; the outer contour of the body is wavy, a through groove is provided in the middle of the body, and the body located on either side of the groove can be elastically deformed into the groove under the action of force. A reset structure can be constructed based on the reset member, and the reset structure can be used on a remote-controlled deformable vehicle. Since the middle part of the reset member is hollowed out, it can produce greater elastic deformation, and then the fitting clearance between the reset member and the cam group can be reduced to about 0.1. During the deformation process of the remote-controlled vehicle, when interference occurs, the reset member can avoid the problem of jamming between the reset member and the cam group due to the effect of elastic deformation. When the interference disappears, the reset member can immediately restore its original shape due to the effect of elastic deformation and maintain an effective fitting clearance with the cam attachment. This solves the problem that the existing remote-controlled deformable vehicle is prone to deviation when driving in a straight line.

[0047] It should be understood that the application of the present invention is not limited to the above examples. For those skilled in the art, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
