Abstract
Description
Technical Field
[0001] This utility model relates to the field of toy cars, and in particular to a toy bumper car. Background Technology
[0002] Bumper cars are a popular amusement ride for children. Controlled by a remote, they can move forward, backward, and turn. Children can operate them from a distance, developing their hand-eye coordination and reaction skills. The bumper cars also feature sound effects when drifting or colliding, providing a rich experience for participating children.
[0003] In existing toy bumper cars, during a two- or multi-car race, the car that is bumped can only be pushed aside, but it doesn't completely lose its ability to continue the race. This allows players to continue playing for a long time, resulting in a lack of satisfaction for the winner and a lack of fun for this type of product. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a toy bumper car.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a toy bumper car, including a matching remote control and a bumper car body; the front of the bumper car body is provided with a trigger plate and a flap that can extend into the bottom of the opposite vehicle; after colliding with the opposite vehicle, the trigger plate can press down to release the locking device from locking the flap; the trigger plate is provided with a self-resetting device; the interior of the bumper car body is provided with a locking device, a drive mechanism and a reset mechanism; the locking device is used to lock the flap; the drive mechanism is used to quickly lift the unlocked flap upward to flip the opposite vehicle, and at the same time trigger the reset mechanism to retract the raised flap and lock it through the locking device.
[0006] With the technical solution of this application, when the trigger plate actively or passively collides with an opposing vehicle, the trigger plate will press down to trigger the locking device to unlock and release the lock on the flap. The flap is then quickly lifted by the drive device, flipping the opposing vehicle over during the lifting process, rendering it unable to continue the game. Players need to manually straighten it before they can play again. Simultaneously with the flap lifting, a reset mechanism is triggered, returning the flap to its initial state and locking it again through the locking device. This application's toy bumper car, by triggering the flap upon collision, can flip the opposing vehicle, preventing it from continuing the game. This increases the difficulty of controlling the toy bumper car and enhances the sense of accomplishment after victory, thereby increasing the game's fun.
[0007] A further improvement is made to the locking device, which includes a locking plate, an unlocking plate, and a torsion spring. The locking plate has a locking hole corresponding to the latch of the flap, used to fix the latch. One end of the locking plate is mounted inside the bumper car body via a rotating shaft. One end of the unlocking plate is mounted near the trigger plate via a connecting shaft inside the bumper car body. The other end of the unlocking plate abuts against a limiting shaft located at the other end of the locking plate. When pushed by the trigger plate, the locking plate can lift one end to release the latch of the flap. A torsion spring is mounted on the rotating shaft of the locking plate, with one end abutting against the locking plate and the other end abutting against the housing of the reset mechanism. The torsion spring is used to reset the lifted locking plate. With this technical solution, locking and unlocking are achieved by lifting and lowering the locking plate.
[0008] Further improvements include a drive mechanism comprising a drive disc, a limiting disc, a second torsion spring, and a brake disc. The outer circumference of the drive disc is partially provided with driven teeth that are driven by the reset mechanism. The side wall of the drive disc has a stop for triggering the reset mechanism to start and stop. The limiting disc is located on one side of the reset mechanism housing. An internal gear is located on one side of the limiting disc. The brake disc has elastic one-way limiting teeth that mesh with the internal gear of the limiting disc. The connecting shaft of the brake disc passes through the mounting hole of the limiting disc and connects to the drive disc, allowing the drive disc to rotate around the connecting shaft. The second torsion spring is sleeved on the connecting shaft, with one end fixed to the limiting disc and the other end fixed to the drive disc. The flap is fixed to the drive disc via a mounting shaft. The mounting shaft is installed on the other side of the reset mechanism housing via a shaft-hole mating mechanism. With this technical solution, the brake disc limits the flap to its initial state before a collision occurs, and the second torsion spring allows the flap to be quickly lifted and overturned after the locking is released, thus overturning the oncoming vehicle.
[0009] Further improvements include an interference fit for the hinge plate to be fixed to the mounting shaft. This direct mounting method is simple in structure and easy to install. Alternatively, the hinge plate can be sleeved onto the mounting shaft; both the stop block and the hinge plate have fixing posts; the two ends of the tension spring are fixed to the fixing posts. With this design, the mounting shaft and the two fixing posts form a triangle. Based on the stability of the triangle, the hinge plate and the drive disc are fixed together as a whole. The addition of the tension spring helps prevent the hinge plate from pinching fingers.
[0010] Further improvements include a reset mechanism comprising a motor, a reduction gear set, a contact switch, a sliding block, and a spring. The motor and the reduction gear set are installed inside the housing. The first gear of the reduction gear set is fixed to the drive shaft of the motor. A coaxial drive shaft is provided on the outer side of the last gear of the reduction gear set, and a drive tooth that mates with the driven tooth is partially provided on the outer circumference of the drive shaft. The contact switch is fixed inside the bumper car body, and the sliding block mates with the stop block of the drive disc. An upper baffle and a lower baffle are provided at the corresponding positions of the housing and the sliding block. The upper and lower baffles form a sliding groove for the displacement of the sliding block. A side baffle is fixed on the outer side of the sliding groove. The two ends of the spring are fixedly connected to the contact switch and the sliding block, respectively. The contact switch and the reset motor are electrically connected to the control board installed inside the bumper car body. In the initial state of the lifting plate, the stop block pushes the sliding block and the spring down, the contact switch is turned on, and the motor stops working. As the lifting plate rises to its highest point, the stop block releases the pressure on the spring and the sliding block, the sliding block is pushed backward by the spring, the contact switch is turned off, and the motor starts working. The number of teeth of the drive tooth and the driven tooth is limited by the initial position and the highest point of the lifting plate. By adopting the technical solution of this application, the contact switch is opened or closed by using a stop block to push the sliding block forward or a spring to push the sliding block backward, thereby realizing the conduction or shutdown of the motor. After the motor starts, it drives the reduction gear set to rotate, and the rotation of the reduction gear set drives the driving gear and driven gear to rotate, thereby realizing the reset of the flip plate.
[0011] A further improvement involves mounting one end of the trigger plate to the bumper car body via a shaft and hole connection; the trigger plate has a cavity; the cavity is sealed by a sealing plate fixed to the trigger plate; the self-resetting device includes a collision head and a reset spring; the collision head is hinged to the cavity of the trigger plate via a connecting arm; the trigger plate has a hole; one end of the reset spring is fixed to the collision head, and the other end is fixed to the inner wall of the trigger plate; the collision head extends out of the hole to the outside of the trigger plate under the action of the reset spring; a baffle is provided at the corresponding position of the collision head on the bumper car body. With the technical solution of this application, the automatic reset of the trigger plate is achieved by the collision head striking the baffle.
[0012] A further improvement involves a forced reset device on the top of the bumper car body. This device includes a pressure plate and a spring switch electrically connected to the control board. The spring switch is fixed inside the bumper car body. A mounting groove is provided on the top of the bumper car body. One end of the pressure plate is mounted in the mounting groove via a connecting shaft, and the other end abuts against the spring contact of the spring switch. With this technical solution, pressing down the pressure plate triggers the spring switch, causing it to control the motor of the reset mechanism to rotate, thus forcibly resetting the flap.
[0013] A further improvement involves a forced reset device on the top of the bumper car body. This device includes a pressure plate and a resilient switch electrically connected to the control board. The resilient switch is fixed inside the bumper car body. A mounting groove is located on the top of the bumper car body. One end of the pressure plate is mounted in the mounting groove via a connecting shaft. A torsion spring is mounted on the connecting shaft of the pressure plate, with one end of the torsion spring abutting against the pressure plate and the other end abutting against the inner wall of the bumper car body. The other end of the pressure plate is positioned above the spring of the resilient switch. By adopting the technical solution of this application, pressing down the pressure plate triggers the resilient switch, causing it to control the motor of the reset mechanism to rotate, thus achieving the purpose of forcibly resetting the flap.
[0014] Further improvements include two drive wheels and one omnidirectional wheel located beneath the bumper car's main body; the two drive wheels and the omnidirectional wheel are arranged in an isosceles triangle; each drive wheel is connected to a differential motor; the bumper car's main body also houses a horn and LED lights; the differential motors, horn, and LED lights are electrically connected to the control board; amplification holes are located on the bumper car's main body corresponding to the horn; a power supply box and a power switch are located at the bottom of the bumper car's main body, with the power supply installed inside the power supply box; the power switch is installed in a switch slot at the bottom of the bumper car's main body; the height of the power switch is less than the depth of the switch slot; the power supply is electrically connected to both the control board and the power switch. With this technical solution, the bumper car can quickly turn left and right to avoid collisions with oncoming vehicles, and the horn and LED lights can enhance the atmosphere through sound and light.

[0030] Alternatively, a forced reset device may be provided on the top of the bumper car body; the forced reset device includes a pressure plate 32 and an elastic switch 33 electrically connected to the control board; the elastic switch is fixed inside the bumper car body; the top of the bumper car body is provided with a mounting groove 34; one end of the pressure plate is installed in the mounting groove through a connecting shaft, and a torsion spring 3 is installed on the connecting shaft of the pressure plate, one end of the torsion spring 3 abuts against the pressure plate, and the other end abuts against the inner wall of the bumper car body; the other end of the pressure plate is located above the elastic switch spring.
[0031] To better illustrate the technical solution of this application, the gameplay of the toy bumper cars will now be further explained.
[0032] Insert the batteries into the battery compartment and turn on the power switches of both the remote control and the bumper car. Place the bumper cars on the ground or a battle platform. Players can control the bumper cars to move forward, backward, and turn left and right using the remote control. The toys can actively attack and collide with other vehicles, or actively avoid collisions. When one vehicle's flap 3 can penetrate to the bottom of the opposite vehicle, it can actively collide with the opposite vehicle. The collision causes the trigger plate 2 to press down, which in turn pushes the unlocking plate to rotate. The rotation of the unlocking plate 5 lifts the limiting shaft 10 upward, thereby lifting one end of the locking plate 4. After the locking plate is lifted, the lock hole 8 is released from the latch 7, and the flap 3 is lifted by the torsion spring 2. The rapid lifting of the flap 3 can directly flip the opposite vehicle.
[0033] During the lifting process, the external force of the stop block on the sliding block is released. Due to the reaction force of the spring, the sliding block moves backward, causing the contact switch to open. After the contact switch opens, the control board inputs a command to the motor, which drives the reduction gear set to rotate. The rotation of the reduction gear set drives the drive gear on the drive shaft to rotate. After the lift is raised to its highest point, the driven gear is in a waiting state. When the drive gear rotates to mesh with the driven gear, it drives the driven gear to rotate, thus bringing the lift back to its initial state from the highest point. When the lift returns to its initial position, the meshing between the driven gear and the drive gear is released (because the drive gear and driven gear are both locally designed, they can achieve non-interference). At the same time, the stop block pushes the sliding block forward and downward to press the spring, thus triggering the contact switch to open. After the switch is open, the control board outputs a command to the motor to stop rotating. Due to the combined action of the brake disc and the locking mechanism, the lift will be confined to its initial position. This allows it to continue fighting and collide with other vehicles or wait for the opponent to manually restore the overturned vehicle before engaging in combat again. The technical solution of this application enhances the fun of the toy by overturning the opposing vehicle, rendering it incapable of fighting.
[0034] The above embodiments are merely preferred embodiments of this utility model, but this embodiment is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of this utility model shall be considered equivalent substitutions and shall fall within the protection scope of this utility model.
