Description

Technical Field

[0001] This utility model relates to a tumbling remote-controlled car. Background Technology

[0002] Existing stunt remote control cars not only have forward and backward functions, but also front and rear wheel flipping functions. The forward and backward functions are controlled by the first set of motors and gear sets, the front wheel flipping function is controlled by the second set of motors and gear sets, and the rear wheel flipping function is controlled by the third set of motors and gear sets. Therefore, three sets of motors and gear sets need to be installed inside the remote control car to realize the three stunt functions respectively.

[0003] The utility model patent with patent number CN201721224501.3 discloses a remote control car with front and rear combination roll stunts. The front end of the car is supported by the support of the support members, and with the help of the rear wheels and rear roll-over parts, the whole car can roll in various different shapes. Moreover, the mechanism is simple, the car model is novel, and it satisfies the visual experience and is interesting. However, the body structure of the document is complex. Not only is there an imbalance in the body weight, which affects the smoothness of the roll, but there are also problems with the strength and durability of the body structure. The middle part collapses or breaks when there is violent roll, impact or heavy pressure. In addition, its power transmission and torque output have defects, which cannot ensure that the vehicle has enough power to roll and drive. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tumbling remote control car.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A tumbling remote-controlled car includes a body, inflatable wheels mounted on both sides of the body with a diameter greater than the body thickness, the body including a body body, a first body shell fixedly mounted on top of the body body by screws, support brackets fixedly mounted inside the first body shell and snapped onto the body body at both ends, a second body shell fixedly mounted on the bottom of the body body by screws, and a battery compartment cover snapped onto the second body shell, a circuit board with a start switch fixedly mounted on one upper end of the body body, a first side drive motor connected to the circuit board fixedly mounted on one upper side of the body body, a second side drive motor connected to the circuit board fixedly mounted on the other upper side of the body body, a first gear compartment driven by the first side drive motor provided on one side of the body body, a second gear compartment with the same structure as the first gear compartment driven by the first side drive motor provided on the other side of the body body, and a battery compartment for placing a battery and connected to the circuit board through battery terminals provided on the bottom of the body body.

[0007] Preferably, the first gear compartment is provided with a drive gear fixedly connected to the output end of the first side drive motor, a first driven gear installed inside the first gear compartment via a fixed shaft and meshing with the drive gear, a second driven gear installed inside the first gear compartment via a fixed shaft and meshing with the first driven gear, a first hub insert integrally formed with the second driven gear and fixedly installed with the inflatable wheel, a transmission pinion installed inside the first gear compartment via a fixed shaft and meshing with the drive gear, a third driven gear installed inside the first gear compartment via a fixed shaft and meshing with the transmission pinion, a fourth driven gear installed inside the first gear compartment via a fixed shaft and meshing with the third driven gear, a fifth driven gear installed inside the first gear compartment via a fixed shaft and meshing with the fourth driven gear, and a second hub insert integrally formed with the fifth driven gear and fixedly installed with the inflatable wheel.

[0008] Preferably, the first body shell is provided with first body shell mounting bolts.

[0009] Preferably, fastening screws are installed at equal intervals on the support bracket;

[0010] Furthermore, the two ends of the support bracket are integrally formed with mounting plates.

[0011] Preferably, the second body shell is provided with second body shell mounting bolts;

[0012] Furthermore, a rectangular mounting hole corresponding to the battery compartment cover is provided in the center of the second body shell, and a slot for mounting is provided at the rear of the rectangular mounting hole of the second body shell.

[0013] Preferably, one end of the battery compartment cover is integrally formed with retaining teeth, and the other end of the battery compartment cover is provided with battery compartment cover mounting bolts.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The use of a drive gear and multiple driven gears in the first and second gear compartments can significantly amplify the torque output of the motor. In addition, large-diameter inflatable wheels require greater torque to drive, especially when starting, climbing, or overcoming obstacles. This gear system effectively solves this contradiction, ensuring that the vehicle has enough power to roll and move. Furthermore, the identical structure of the first and second gear compartments ensures the symmetry and reliability of the power output of the left and right wheels.

[0016] 2. This utility model clearly states that different functions are achieved by precisely controlling the steering and timing of the two side drive motors: when rotating, the two motors rotate in opposite directions; when rolling, the two motors rotate in the same direction at high speed and then stop suddenly at the same time. By utilizing the inertia generated by the high-speed drive of the vehicle body, combined with the grip and elasticity of the large-diameter inflatable wheels, the entire vehicle body can be rolled without the need for an additional complex flipping mechanism. In addition, the "sudden stop" action is the key physical point that triggers the rollover, making full use of the principle of inertia.

[0017] 3. The layered design of the vehicle body, first body shell, second body shell, and battery compartment cover facilitates assembly, maintenance, and component replacement. The support bracket is connected to the first body shell by fastening screws and is snapped into the vehicle body by a mounting plate to form a stable connection. Moreover, the support bracket is located in the middle of the first body shell, providing key support for the weak area in the middle of the shell, effectively preventing the middle part of the shell from collapsing or breaking during violent rollover, impact, or heavy pressure, greatly improving the overall structural strength and impact resistance of the vehicle body.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0023] Example

[0024] A type of tumbling remote-controlled car, such as Figure 1-4 As shown, it includes a vehicle body 1 and inflatable wheels 2 mounted on both sides of the vehicle body 1, with a diameter greater than the thickness of the vehicle body 1.

[0025] The vehicle body 1 includes a vehicle body 11, a first body shell 12 fixedly installed on the upper part of the vehicle body 11 by screws, a support bracket 13 fixedly installed inside the first body shell 12 and whose two ends are engaged with the vehicle body 11, a second body shell 14 fixedly installed on the lower part of the vehicle body 11 by screws, and a battery compartment cover 15 fastened to the second body shell 14.

[0026] A circuit board 111 with a start switch is fixedly installed on one upper end of the vehicle body 11. A first drive motor 112 connected to the circuit board 111 is fixedly installed on one upper side of the vehicle body 11. A second drive motor 113 connected to the circuit board 111 is fixedly installed on the other upper side of the vehicle body 11. A first gear compartment 114 driven by the first drive motor 112 is provided on one side of the vehicle body 11. A second gear compartment 115 with the same structure as the first gear compartment 114 is provided on the other side of the vehicle body 11 and driven by the first drive motor 112. A battery compartment 116 for placing a battery and connected to the circuit board 111 through battery terminals is provided below the vehicle body 11.

[0027] The first gear compartment 114 contains a drive gear 1141 fixedly connected to the output end of the first side drive motor 112. A first driven gear 1142 is mounted inside the first gear compartment 114 via a fixed shaft and meshes with the drive gear 1141. A second driven gear 1143 is mounted inside the first gear compartment 114 via a fixed shaft and meshes with the first driven gear 1142. A first hub insert 1144, integrally formed with the second driven gear 1143 and fixedly mounted to the inflatable wheel 2, is also mounted inside the first gear compartment 114 via a fixed shaft and meshes with the drive gear 1141. The transmission pinion 1145 meshes with the wheel 1141; the third driven gear 1146 is installed inside the first gear compartment 114 via a fixed shaft and meshes with the transmission pinion 1145; the fourth driven gear 1147 is installed inside the first gear compartment 114 via a fixed shaft and meshes with the third driven gear 1146; the fifth driven gear 1148 is installed inside the first gear compartment 114 via a fixed shaft and meshes with the fourth driven gear 1147; and the second hub insert 1149 is integrally formed with the fifth driven gear 1148 and fixedly installed with the inflatable wheel 2. Specifically, the first drive motor 112 engages with the gears inside the first gearbox 114 to drive the inflatable wheel 2 on one side of the vehicle body 1. The drive gear 1141, the first driven gear 1142, the second driven gear 1143, the transmission pinion 1145, the third driven gear 1146, the fourth driven gear 1147, and the fifth driven gear 1148 work together to form a multi-stage gear engagement, thereby increasing the torque.

[0028] It should be further explained that the structure of the second gear compartment 115 is the same as that of the first gear compartment 114. In actual operation, the first side drive motor 112 and the second side drive motor 113 operate simultaneously. If it is necessary to control the remote control car to rotate, the first side drive motor 112 and the second side drive motor 113 must be controlled to rotate in opposite directions. For example, if the first side drive motor 112 is controlled to rotate clockwise to drive the inflatable wheel to rotate, the second side drive motor 113 is controlled to rotate counterclockwise to drive the inflatable wheel to rotate. At this time, the remote control car will rotate. If it is necessary to control the remote control car to flip, the first side drive motor 112 and the second side drive motor 113 must be controlled to rotate in the same direction, and the first side drive motor 112 and the second side drive motor 113 must be controlled to stop suddenly at the same time, so that the car body 1 can flip over under inertia through the inflatable wheel.

[0029] The first body shell 12 is provided with a first body shell mounting bolt 121. Specifically, the first body shell mounting bolt 121 passes through the first body shell 12 and is screwed into the body body 11 to complete the fixed installation of the first body shell 12.

[0030] Fastening screws 131 are installed at equal intervals on the support bracket 13. Specifically, the fastening screws 131 pass through the support bracket 13 and are fixedly installed with the first body shell 12.

[0031] The two ends of the support bracket 13 are integrally formed with mounting plates 132. Specifically, the support bracket 13 is inserted into the body body 11 through the mounting plates 132, so that the support bracket 13 serves as an auxiliary support mechanism to support the first body shell 12, preventing the middle part of the first body shell 12 from becoming fragile due to the lack of a support mechanism, and improving the structural strength of the first body shell 12 during driving and rolling, making it less prone to breakage and damage.

[0032] The second body shell 14 is provided with a second body shell mounting bolt 141. Specifically, the second body shell mounting bolt 141 passes through the second body shell 14 and is screwed into the body body 11 to complete the fixed installation of the second body shell 14.

[0033] The second body shell 14 has a rectangular mounting hole 142 corresponding to the battery compartment cover 15 at its central position, and a slot-type mounting part 143 is provided at the rear of the rectangular mounting hole 142.

[0034] One end of the battery compartment cover 15 is integrally formed with a retaining tooth 151, and the other end of the battery compartment cover 15 is provided with a battery compartment cover mounting bolt 151. Specifically, when installing the battery compartment cover 15, the retaining tooth 151 is first inserted into the slot of the mounting part 143, and then the battery compartment cover mounting bolt 151 is passed through the battery compartment cover 15 and screwed into the second body shell 14 to complete the fixed installation of the battery compartment cover 15.

[0035] It should be further explained that the inflatable wheel 2 naturally possesses excellent shock absorption and cushioning properties, effectively absorbing the impact of rolling, jumping, and landing, protecting the internal precision electronic components and gear structure. Moreover, it provides good grip for driving, and the elastic properties of the inflatable wheel 2 are also an important physical basis for achieving inertial rolling motion.

[0036] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
