Description

Technical Field

[0001] This invention relates to the field of children's electric vehicle technology, and in particular to children's electric vehicles with protective structures. Background Technology

[0002] A child electric vehicle is an electric vehicle driven by a child. It is mainly used in closed areas such as residential areas and parks. There are two ways to control a child electric vehicle: one is for the parent to operate the remote control, and the other is for the child to drive it themselves.

[0003] However, children often have a weak sense of safety. When children are driving, their parents need to supervise them. However, park environments are quite complex. Many parks have ponds or are built on the shore of lakes. Therefore, when children are driving on the shore, they may accidentally slip into the water. In a panic, the children may speed into the water, and the parents next to them often cannot stop them in time, which may result in personal injury to the drivers. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a child electric vehicle with a protective structure.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a child electric vehicle with a protective structure, comprising a vehicle body, on which a water wading detection device, a braking device, and an air cushion device are installed. The water wading detection device includes a sliding channel, a buoyancy ball, and a top contact rod. The sliding channel is located at the front end of the vehicle body. The buoyancy ball is elastically guided and slidably disposed within the sliding channel. One end of a first pull rope is connected to the lower end of the buoyancy ball, and the other end is connected to the braking device. The braking device is mounted on the vehicle's wheel axle for braking the vehicle. The lower end of the sliding channel is open, allowing water to enter from the lower end of the sliding channel when the vehicle is wading through water. The buoyancy ball floats upward, tightening the first pull rope to actively brake the vehicle. The air cushion device includes a protective air cushion and an air tank. The airbag is mounted on the vehicle body to cushion the impact force when the vehicle collides with an obstacle. An inflatable airbag is located at the lower end of the protective airbag, which is connected to an air tank via a pipe. A switch plate is elastically slidably mounted on the cross-section of the pipe, controlling whether the pipe is open or closed. A sliding groove is provided on the sliding channel, and a top contact rod is elastically slidably mounted within the sliding groove. The front end of the top contact rod is located within the sliding groove, and a pull block is located at the rear end of the top contact rod. One end of a second pull rope is located on the front surface of the pull block, and the other end is located on the rear surface of the switch plate. When the buoyancy ball rises to a certain height, it touches the top contact rod. Upon being touched, the top contact rod slides backward, pulling the second pull rope. The second pull rope then pulls the switch plate open, inflating the airbag and increasing the vehicle's buoyancy.

[0006] Its beneficial effect is that when the vehicle is wading through water, it can actively brake to stop the vehicle. If the slope is too steep and the vehicle cannot stop immediately and slides into the water, it can automatically trigger the deployment of the inflatable airbags at the bottom of the vehicle, so that the vehicle floats on the water and protects the personal safety of the children driving the vehicle.

[0007] In the above scheme, preferably, when the inflatable airbag is inflated, its bottom surface extends beyond the bottom surface of the wheel, thereby elastically contacting the ground and increasing friction with the ground to assist vehicle braking.

[0008] In the above scheme, preferably, the vehicle body is also provided with a protective device, which includes a lifting linkage assembly, a hydraulic cylinder, and a lifting barrier. The lifting linkage assembly includes a first link and a second link. One end of the first link and the second link are respectively rotatably mounted on the vehicle body pedal plane and the bottom surface of the lifting barrier, respectively. The two links are rotatably connected together at their middle positions, and the other ends are respectively slidably connected on the bottom surface of the lifting barrier and the vehicle body pedal plane. The telescopic rod on the hydraulic cylinder is set on the sliding end of the second link. The hydraulic cylinder extends forward, and the lifting linkage assembly can push the lifting barrier to move upward.

[0009] In the above-mentioned scheme, preferably, the upper end of the soft membrane is arranged around the bottom surface of the lifting fence, and the lower end of the soft membrane is set on the pedal of the vehicle body. When the lifting fence rises, it drives the soft membrane to rise. The lifting fence and the soft membrane combine to form a cavity with a sealed upper opening. The seat on the vehicle body is located inside the lifting fence.

[0010] In the above scheme, preferably, an impeller shaft is provided inside the pipeline, and the impeller shaft is connected to a hydraulic pump. The rotation of the hydraulic pump can drive the hydraulic cylinder to extend forward.

[0011] Its beneficial effect is that when the vehicle enters the water, the inflatable airbags deploy and the lifting railings move upwards, forming a cabin shape, further protecting the safety of children in the driver's cabin.

[0012] In the above scheme, preferably, the vehicle body is also provided with a nailing and anchoring device, which includes an anchor, a first elastic element, an anchor rope and a locking device. The anchor is guided and slidably disposed on the vehicle body, one end of the anchor rope is disposed on the anchor and the other end is disposed on the vehicle body, the first elastic element elastically contacts the rear end of the anchor, and the locking device locks the anchor. When the locking device is unlocked, the anchor can be nailed to the ground under the action of the first elastic element, and is connected to the vehicle body through the anchor rope.

[0013] In the above scheme, preferably, the locking device includes a locking pin, a third pull rope is connected to the rear end of the locking pin, the other end of the third pull rope is connected to the switch plate, a second elastic element is also sleeved on the third pull rope, and a locking hole is opened on the anchor. Under the action of the second elastic element, the front end of the locking pin elastically contacts the locking hole, and the switch plate slides upward to pull the locking pin away from the locking hole through the third pull rope, thereby unlocking the anchor.

[0014] Its beneficial effect is that when the inflated airbag is deployed, the anchor bolts automatically unlock and are nailed to the ground, connecting to the vehicle via anchor ropes, preventing the inflated vehicle from drifting around on the water.

[0015] The beneficial effects of this invention are as follows: This invention provides a child electric vehicle with a protective structure, which can actively brake to stop the vehicle when it is wading through water. If the vehicle cannot stop immediately when it slides into the water due to the steep slope, it can automatically trigger the deployment of the inflatable airbag at the bottom of the vehicle, so that the vehicle floats on the water surface and protects the personal safety of the child driving the vehicle. At the same time, when the inflatable airbag is deployed, the anchor bolts are automatically unlocked and nailed to the ground, and connected to the vehicle through the anchor rope to prevent the inflated vehicle from drifting around on the water surface.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-7A child electric vehicle with a protective structure includes a vehicle body 1. The vehicle body 1 is equipped with a water wading detection device 2, a braking device 3, an air cushion device 4, a protective device 5, and an anchoring device 6. The water wading detection device 2 is located at the front end of the vehicle body 1 and includes a sliding channel 21, a buoyancy ball 22, and a top contact rod 23. The sliding channel 21 is located at the front end of the vehicle body 1, with an opening at the lower end and a vent at the upper end, allowing water to enter the sliding channel 21 when the vehicle is wading. A guide post 212 is also provided within the sliding channel 21, guiding the buoyancy ball 22 to slide smoothly along the guide post 21. 2. A third elastic element 213 is sleeved on the guide post 212, with its two ends respectively touching the upper end face of the buoyancy ball 22 and the upper end face of the sliding channel 21, so that the buoyancy ball 22 will not move when the vehicle vibrates. When the vehicle is wading through water, the buoyancy ball 22 slides upward under the action of the buoyancy of the water. One end of the first pull rope 24 is connected to the lower end face of the buoyancy ball 22, and the other end is connected to the brake device 3. The brake device 3 is set on the vehicle wheel axle and is used to brake the vehicle. When the vehicle is wading through water, the buoyancy ball 22 rises and pulls the brake device 3 through the first pull rope 24 to perform the braking operation, so that the vehicle can automatically start the braking operation as soon as it is wading through water.

[0024] When encountering a sloping road surface, the downward sliding force of the vehicle on the slope varies depending on the angle of the slope. When the vehicle continues to move downhill due to insufficient braking force, the horizontal plane in the sliding channel 21 rises, causing the buoyancy ball 22 to continue to rise. This increases the braking force of the first pull rope 24 on the braking device 3, further assisting the vehicle to stop.

[0025] Because the slope angle was too steep, the vehicle could not be stopped even when the braking device 3 was fully loaded, and the vehicle continued to slide down and into the water.

[0026] The air cushion device 4 includes a protective air cushion 41 and an air tank 42. The air tank 42 is initially filled with a certain amount of compressed air. The protective air cushion 41 is arranged in a ring around the front, rear, left, and right sides of the vehicle body 1. The protective air cushion 41 is made of flexible material and is filled with air. When the vehicle collides with an obstacle while driving, the protective air cushion 41 acts as a buffer, protecting the safety of the occupants. Simultaneously, when the vehicle is wading through water, the protective air cushion 41 also provides some buoyancy. A deflated inflatable airbag 43 is fixedly installed at the bottom of the protective air cushion 41. 3 is connected to the gas storage tank 42 through a pipe 44. A switch plate 45 is elastically slidably arranged on the cross-section of the pipe 44. A vent hole 451 is provided on the switch plate 45. A sliding groove 211 is provided on the side at the upper position of the sliding channel 21. The top contact rod 23 is elastically slidably arranged in the sliding groove 211. The front end of the top contact rod 23 is located in the sliding channel 21, and a pull block is provided at the rear end. One end of the second pull rope 25 is provided on the front end face of the pull block, and the other end is provided on the rear end face of the switch plate 45. After the buoyancy ball 22 rises to a certain height, it can touch the top contact rod 23.

[0027] In the initial state, the switch plate 45 is in a blocked state under the action of the elastic element at the upper end of the pipe 44. When the front end of the vehicle slides into the water, the buoyancy ball 22 slides upward and touches the upper end of the sliding channel 21. At this time, the spherical surface of the buoyancy ball 22 touches the top contact rod 23. Under the action of the top contact force, the top contact rod 23 slides backward, thereby pulling the pull block at the rear end to move one end of the second pull rope 25, pulling the switch plate 45 to move upward. At this time, the vent 451 is connected to the pipe 44, making the pipe 44 unobstructed. The compressed air in the air tank 42 directly enters the deflated inflatable airbag 43, causing the inflatable airbag 43 to inflate. At this time, the inflatable airbag 43 presses against the ground. The inflatable airbag 43 below the position where the vehicle has not entered the water rubs against the ground, increasing the friction between the vehicle and the ground, thereby further assisting the vehicle to stop. At the same time, the buoyancy provided by the inflatable airbag 43 when it is inflated can make the vehicle float on the water surface.

[0028] The anchoring device 6 includes an anchor 61, a first elastic element 62, an anchor rope 63, and a locking device 64. An anchor track is provided behind the seat of the vehicle body 1, with an opening at the bottom. The anchor 61 is guided and slidably disposed within the anchor track, sliding downwards to exit from the bottom of the vehicle and anchor onto the ground. The first elastic element 62 is located within the anchor track, with one end pressing against the anchor 61 and the other end pressing against the upper surface of the anchor track. One end of the anchor rope 63 is connected to the upper surface of the anchor 61, and the other end is disposed on a reel. The reel is rotatably mounted on the seat back. The locking device 64 includes a locking pin 641, a second elastic element 642, and... The third pull rope 643 has a locking track on the side of the anchor slide. The locking pin 643 is guided and slidably disposed in the locking track. One end of the third pull rope 643 is connected to the rear end of the locking pin 641, and the other end is connected to the lower end of the switch plate 45. The second elastic element 642 is sleeved on the locking pin 641, and its two ends respectively abut against the limiting ring of the locking pin 641 and the rear end face of the locking track. The anchor 61 has a locking hole 611. Under the action of the second elastic element 642, the front end of the locking pin 641 abuts against the locking hole 611, thereby locking the anchor 61 in the anchor slide. At this time, the first elastic element 62 is in a compressed state.

[0029] When the vehicle is in water, the switch plate 45 is pulled upwards and simultaneously pulls the locking pin 641 away from the locking hole 611. The anchor 61 is launched downwards by the first elastic element 62 at the rear end and finally nails to the ground below. There is no inflatable airbag 43 behind the anchor 61. Therefore, after the anchor 61 is nailed to the ground, when the vehicle continues to slide down into the water, the anchor rope 63 is pulled out. This prevents the vehicle from drifting away after it slides into the water, making it easy for parents to pull the vehicle back to the shore immediately.

[0030] Children are very uneasy when a vehicle is wading through water, so an additional layer of protection is needed around the driver's cabin. The protective device 5 includes a lifting linkage assembly 51, a hydraulic cylinder 53, and a lifting barrier 52. The lifting linkage assembly 51 includes a first link 511 and a second link 512, which are intersected and rotatably connected at their midpoint via a rotating shaft. The rear ends of the first link 511 and the second link 512 are rotatably mounted on the vehicle body 1's pedal surface and the bottom surface of the lifting barrier 52, respectively. Guide wheels 5111 are rotatably mounted on the other ends of both links. Each of the components is equipped with a guide rail 521. The guide wheel 5111 on the first connecting rod 511 is guided and slidably disposed within the guide rail 521 of the lifting fence 52. The guide wheel 5111 on the second connecting rod 512 is guided and slidably disposed on the guide rail 521 of the vehicle body 1 pedal. The hydraulic cylinder 53 is fixedly disposed on the vehicle body 1 pedal, and the telescopic rod of the hydraulic cylinder 53 is rotatably disposed at the front end of the second connecting rod 512. An impeller shaft 441 is disposed in the pipe 44. The impeller shaft 441 is connected to a hydraulic pump. The rotation of the hydraulic pump can drive the hydraulic cylinder 53 to extend forward. A soft membrane 54 is disposed between the bottom surface of the lifting fence 52 and the surface of the vehicle body 1 pedal.

[0031] When the switch plate 45 is opened to inflate the airbag 43, the passing gas drives the impeller on the impeller shaft 441 to rotate, which in turn drives the hydraulic pump to rotate, causing the hydraulic cylinder 53 to extend forward. This causes the front end of the second connecting rod 512 to move backward. Under the action of the crossbar group, the lifting fence 52 is lifted upward, and at the same time, the upper end of the diaphragm 54 is moved upward. When the diaphragm 54 is tightened up and down, the hydraulic cylinder 53 is also extended to its maximum position. At this time, the lifting fence 52 and the diaphragm 54 surround the driver's cabin, giving the child in the driver's cabin a certain sense of security. At the same time, the lifting fence 52, the diaphragm 54 and the vehicle body 1 pedal form a sealed cavity around the upper opening of the driver's cabin. At this time, even if the airbag 43 is punctured, the cavity formed by the lifting fence 52 forms a cabin, which can make the vehicle float on the water and prevent water from entering the driver's cabin, further protecting the safety of the child in the driver's cabin.

[0032] Its working principle or usage method is as follows:

[0033] When encountering a sloping road surface, the downward sliding force of the vehicle on the slope varies depending on the angle of the slope. When the vehicle continues to move downward due to insufficient braking force, the horizontal plane in the sliding channel 21 rises, causing the buoyancy ball 22 to continue to rise. This increases the braking force of the first pull rope 24 on the braking device 3, further assisting the vehicle to stop.

[0034] When the slope angle is too large, even when the braking device 3 is fully loaded, the vehicle cannot stop and continues to slide down into the water. When the front of the vehicle slides into the water, the buoyancy ball 22 slides upward and touches the upper end of the sliding channel 21. At this time, the spherical surface of the buoyancy ball 22 touches the top contact rod 23. Under the action of the top contact force, the top contact rod 23 slides backward, thereby pulling the pull block at the rear end to move one end of the second pull rope 25, which pulls the switch plate 45 to move upward. At this time, the vent 451 is connected to the pipe 44, making the pipe 44 unobstructed. The compressed air in the air tank 42 directly enters the deflated inflatable airbag 43, causing the inflatable airbag 43 to inflate. At this time, the inflatable airbag 43 presses against the ground. The inflatable airbag 43 below the unwatered position of the vehicle rubs against the ground, increasing the friction between the vehicle and the ground, thereby further assisting the vehicle to stop. At the same time, the buoyancy provided by the inflatable airbag 43 when it is inflated allows the vehicle to float on the water surface.

[0035] When the vehicle is in water, the switch plate 45 is pulled upward and slides upward. Simultaneously, the switch plate 45 pulls the locking pin 641 away from the locking hole 611. The anchor 61 is launched downward under the action of the first elastic element 62 at the rear end and finally nails to the ground below. There is no inflatable airbag 43 behind the anchor 61. Therefore, after the anchor 61 is nailed to the ground, when the vehicle continues to slide down into the water, the anchor rope 63 is pulled out. This prevents the vehicle from drifting away after it slides into the water, making it easy for parents to pull the vehicle back to the shore immediately.

[0036] When the switch plate 45 is opened to inflate the airbag 43, the passing gas drives the impeller on the impeller shaft 441 to rotate, thereby driving the hydraulic pump to rotate and causing the hydraulic cylinder 53 to extend forward. This causes the front end of the second connecting rod 512 to move backward. Under the action of the crossbar group, the lifting fence 52 is lifted upward, and at the same time, the upper end of the diaphragm 54 is moved upward. When the diaphragm 54 is tightened up and down, the hydraulic cylinder 53 is also extended to its maximum position. At this time, the lifting fence 52 and the diaphragm 54 surround the driver's cabin, giving the child in the driver's cabin a certain sense of security. At the same time, the lifting fence 52, the diaphragm 54 and the vehicle body 1 pedal form a sealed cavity around the upper opening of the driver's cabin. At this time, even if the airbag 43 is punctured, the cavity formed by the lifting fence 52 rising up forms a cabin, which can make the vehicle float on the water and prevent water from entering the driver's cabin, further protecting the safety of the child in the driver's cabin.
