Description

Technical Field

[0001] The utility model relates to the technical field of toy cars, in particular to a new type of twist car. Background Art

[0002] With the improvement of living standards, there are various toy cars on the market at present, and children's remote control toy cars are more and more popular among children.

[0003] At present, most remote control twist cars adopt double rear-wheel drive or double front-wheel drive to realize the forward or backward movement of the remote control car.

[0004] The two motors of the double rear-wheel drive or the two motors of the double front-wheel drive are directly fixed on the front and rear wheel frames of the twist car to drive the corresponding wheels. For example, the first motor of the double rear-wheel drive drives the first rear wheel through a transmission structure, and the second motor drives the second rear wheel through a transmission member mechanism. In order to ensure that the toy car does not shake and sway during running, the axes of the first rear wheel and the second rear wheel need to be kept in a straight line.

[0005] However, without precise position limitation, the output shafts of the two directly fixed first motor and second motor are likely to be misaligned. Or due to long use time and many times of falling, an included angle appears between the output shafts of the first motor and the second motor, resulting in the twist car being unable to go straight or swaying left and right during running. At the same time, it also causes poor sensitivity of the user's remote control and inability to finely control the posture and route of the twist car.

[0006] In addition, for existing twist cars, the control circuit board is generally installed flat in the vehicle body, and the bottom area of the vehicle body needs to be larger than the size of the control circuit board, occupying a large space, and the overall size of the toy car is large. Summary of the Invention

[0007] Based on this, in order to solve the above technical problems in the traditional technology, the utility model proposes a new type of twist car that uses a wave box shell with an axisymmetric structure to combine a motor and a transmission component for driving wheels. One of the two transmission components is rotated 180 degrees to form an integral drive group, and combined with the assembly angle set by the wave box shell, it is ensured that the drive shafts of the two transmission components for the wheels are always on the same straight line, improving the smoothness of driving, as well as the sensitivity and fineness of control, and enhancing the product use experience.

The first torque mechanism includes a first connecting member, a first push rod and a first eccentric disk. The first push rod is eccentrically fixed to the first connecting member, and the end is accommodated in a first interference groove of the first eccentric disk; the second torque mechanism includes a second connecting member, a second push rod and a second eccentric disk. The second push rod is eccentrically fixed to the second connecting member, and the end is accommodated in a second interference groove of the second eccentric disk; one end of the square shaft is connected to the first eccentric disk, and the other end is connected to the second eccentric disk.

[0012] In the posture sensing design, the control circuit board includes a sensing touch ring and a brush member. A brush plate that rotates therewith is fixed on the square shaft. The brush plate is provided with a plurality of toggle posts that are inserted into the brush member. The brush member is provided with a plurality of brush shrapnel that are used for sliding contact with the sensing touch ring. The square shaft is suspended in the air and passes through the control circuit board and the brush member.

[0013] To increase the driving torque output to the wheels, the first to fourth transmission components each include an intermediate shaft and a drive shaft. An output gear and a drive gear pair are installed on the drive shaft and connected to the corresponding front or rear wheels. An intermediate gear pair is installed on the intermediate shaft. The motor gear of the motor meshes with the drive gear pair, the drive gear pair meshes with the intermediate gear pair on the intermediate shaft, and the intermediate gear pair meshes with the output gear to transmit torque.

[0014] To ensure the linear relationship of the drive shaft, the first to fourth gearbox housings each include a battery compartment, a drive part, and a drive shaft tube. The corresponding drive shaft is tightly fitted and installed inside the drive shaft tube. The battery compartment is provided with a motor hole.

[0018] The beneficial effects of the present utility model are:

[0019] For the new torsion vehicle of the present utility model, the new torsion vehicle of the present utility model uses a gearbox housing with an axially symmetric structure to rotate one of the two transmission components by 180 degrees to form a drive group for the front or rear wheels. Combining the set assembly angle of each pair of assembled gearbox housings, it can ensure that the drive shafts on both sides of the gearbox housing that mesh with the motor output and are connected to the corresponding wheels are always on the same straight line, enabling the torsion vehicle to drive in a straight line better in the special driving states of transverse or 45-degree angles, and improving the control sensitivity of the user at the remote control end and the response fineness of the vehicle. For example, the axial symmetry of the present utility model means that the structure can coincide with another structure after rotating 180° around a certain line, including Figure 2 the axial symmetry between the front gearbox housing and the front drive group and the rear gearbox housing and the rear drive group shown with respect to the vehicle body center line; it also includes Figure 5 the axial symmetry between the first gearbox housing 60 and the second gearbox housing 70 with respect to the edge B as shown.

[0020] For the new type of twistable vehicle of the present utility model, the control circuit board is vertically placed in the vehicle body, and the square shaft for adjusting the posture passes through the control circuit board, which reduces the production process while enabling the vehicle body to have a more streamlined space. In addition, each wheel of the two front wheels is driven by a corresponding motor, and each wheel of the two rear wheels is driven by a corresponding motor. Therefore, the twistable vehicle can be designed as a special small four-motor drive structure, which improves the driving performance of the twistable vehicle while ensuring its stability performance.

[0021] For the new type of twistable vehicle of the present utility model, a transmission sensing ring is arranged on the control circuit board. The brush member and the brush plate are linked with the square shaft together. A plurality of brush spring pieces of the brush member slide on the transmission sensing ring on the control circuit board to collect the vehicle body deformation posture data. By integrating the control circuit board with the brush structure, while improving the stability of the product posture control, the production process steps are reduced.

[0022] The new type of twistable vehicle of the present utility model can realize the height change of the vehicle body relative to the front end or the rear end of the vehicle. When the twistable vehicle needs to cross a relatively high obstacle, such as Figure 11 the deformation state shown, the vehicle body arches relative to the front wheel frame and the rear wheel frame through the first and second twisting mechanisms so as to pass the obstacle, travel horizontally or obliquely and climb a steep slope, which improves the usage pleasure and user experience.
