Description

Technical Field

[0001] This utility model relates to the field of children's vehicle technology, and in particular to an electric children's vehicle with anti-slip and shock-absorbing functions. Background Technology

[0002] In recent years, electric children's vehicles have become popular in cultural activity squares and residential communities in cities of all sizes across China. Children's vehicles are a type of tool vehicle used by children for play. Currently, there are many different types of electric children's vehicles in use, but some shortcomings still exist.

[0003] The applicant discovered through a search that a Chinese patent discloses "An Electric Children's Vehicle with Anti-slip and Shock-absorbing Function," with publication (announcement) number "CN218055446U." This patent mainly includes a base plate, with a shock-absorbing seat fixed to the top of the base plate. The inner wall of the shock-absorbing seat has a sliding groove. This utility model utilizes a shock-absorbing seat, inclined plate, sunshade, fixed column, force plate, limiting plate, abutment plate, sliding groove, spring, movable column, and rubber ring working together. When bumps occur during the ride, the movable column lowers and compresses the rubber ring, causing the rubber ring to... The deformation, along with the compression plate and spring at the bottom, buffers and reduces the impact force. However, in the existing technology, the shock absorption is achieved by the spring and rubber ring. After long-term use, the rubber ring is prone to aging. With the passage of time and the increase in the number of uses, the rubber will gradually lose its elasticity, thereby reducing the shock absorption effect. In addition, the rubber ring is easy to attract dust, dirt and moisture, making it relatively difficult to clean. The accumulated dirt may affect the performance and life of the rubber ring. Therefore, we propose an electric children's stroller with anti-slip and shock absorption function. Utility Model Content

[0004] The purpose of this utility model is to provide an electric children's vehicle with anti-slip and shock-absorbing functions, in order to solve the problems mentioned in the background art, where the existing technology uses springs and rubber rings for shock absorption. However, the rubber rings are prone to aging after prolonged use. As time goes by and the number of uses increases, the rubber gradually loses its elasticity, thereby reducing the shock absorption effect. Furthermore, the rubber rings easily attract dust, dirt, and moisture, making them relatively difficult to clean. The accumulated dirt may affect the performance and lifespan of the rubber rings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric children's vehicle with anti-slip and shock-absorbing functions, including a vehicle body, a seat cushion inside the vehicle body, a shock-absorbing device at the bottom of the seat cushion, an anti-slip device at the bottom of the vehicle body, the shock-absorbing device including a fixed block and a fixed cylinder, the fixed block being connected to a limit block, a strong spring and a sliding block via a straight rod, the sliding block being connected to a connecting block via a connecting rod, and the fixed cylinder being connected to a buffer pad via a return spring.

[0006] As a preferred embodiment, the anti-slip device includes a connecting plate and a hydraulic cylinder. The connecting plate is connected to a tire via a connecting shaft, and the hydraulic cylinder is connected to a roller via a metal block.

[0007] As a preferred embodiment, the fixing block is fixedly installed on the bottom surface of the vehicle body and located at the bottom axis of the seat cushion. The middle part of the straight rod is fixedly installed inside the fixing block. Two sets of limiting blocks are provided and fixedly installed at both ends of the straight rod. The bottom of the two sets of limiting blocks is fixedly installed on the bottom surface of the vehicle body. Two sets of sliding blocks are provided and symmetrically arranged about the fixing block. Both sets of sliding blocks are slidably connected to the circumferential surface of the straight rod. Two sets of connecting blocks are provided and fixedly installed on the bottom surface of the seat cushion.

[0008] As a preferred embodiment, the two ends of the strong spring are respectively fixedly installed on the opposite side surface of the limiting block and the sliding block, the strong spring is slidably connected to the circumferential surface of the straight rod, the two ends of the connecting rod are respectively rotatably connected to the inside of the sliding block and the connecting block, and four sets of fixed cylinders are provided, which are respectively fixedly installed on the surface of the vehicle body and located at the bottom four corners of the seat cushion.

[0009] As a preferred embodiment, the return spring is fixedly installed inside the fixed cylinder, the buffer pad is fixedly installed on the top of the return spring, and the buffer pad is fixedly connected to the bottom of the seat cushion.

[0010] As a preferred embodiment, the connecting plates are provided in two sets and are fixedly installed on the front and rear sides of the bottom of the vehicle body, and the connecting shafts are provided in two sets and are fixedly installed on the left and right ends between the two sets of connecting plates. The tire is rotatably connected to the circumferential surface of one end of the connecting shaft. The circumferential surface of the tire has multiple grooves and diagonal stripes arranged in a circular pattern, and several of the grooves and diagonal stripes are arranged alternately.

[0011] As a preferred embodiment, the hydraulic cylinders are provided in four sets and are all fixedly installed on the bottom outer surface of the vehicle body. The four sets of hydraulic cylinders are arranged symmetrically in front, behind, left, and right. The metal blocks are provided in four sets and are respectively fixedly installed on the ends of the four sets of hydraulic cylinders away from the vehicle body. The metal blocks are fixedly connected to each other by a fixed shaft. The roller is rotatably connected to the circumferential surface of the fixed shaft. The roller does not contact the tire or the connecting shaft.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By incorporating a shock-absorbing device, when a child sits on the seat, the connecting block presses against the sliding block via the connecting rod. At this time, the strong spring and the return spring are under force. The strong spring pulls the sliding blocks on both sides to move on the surface of the straight rod, and the buffer pad presses against the return spring. When the stroller encounters uneven road surfaces during travel, the strong spring and the return spring can play an important role in buffering. Two strong springs are used and installed symmetrically, which improves stability. When the tire passes over bumps or depressions, the strong spring and the return spring will quickly compress or extend, absorbing the impact force transmitted from the road surface to the vehicle body and converting the impact force from potholes into the elastic potential energy of the spring. This can prevent children from directly feeling strong vibrations and make them more comfortable during the ride.

[0014] By incorporating anti-skid devices, multiple alternating grooves and diagonal stripes are created on the tire surface. These grooves and stripes increase the friction between the tire and the ground, creating more contact points and irregular contact surfaces. This allows for better grip on the ground, improving tire traction and preventing skidding. In rainy weather or when the ground is wet, a hydraulic cylinder lowers the rollers to contact the ground, increasing the contact area. Furthermore, water is squeezed between the tire and the ground and promptly drained through the grooves and stripes, preventing the formation of a water film that reduces tire-ground friction and causes the vehicle to skid.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see the appendix Figure 1 - Appendix Figure 7 An electric children's stroller with anti-slip and shock-absorbing functions includes a body 1, a seat cushion 2 inside the body 1, a shock-absorbing device 4 at the bottom of the seat cushion 2, and an anti-slip device 3 at the bottom of the body 1. The shock-absorbing device 4 includes a fixing block 401 and a fixing cylinder 408. The fixing block 401 is connected to a limit block 403, a strong spring 405, and a sliding block 404 via a straight rod 402. The sliding block 404 is connected to a connecting block 406 via a connecting rod 407. The fixing cylinder 408 is connected to a buffer pad 410 via a return spring 409. The fixing block 401 is fixedly installed on the bottom surface of the body 1 and located at the bottom axis of the seat cushion 2. The middle of the straight rod 402 is fixedly installed inside the fixing block 401. Two sets of limit blocks 403 are provided and fixedly installed at both ends of the straight rod 402. The bottoms of the two sets of limit blocks 403 are fixedly installed on the bottom surface of the body 1. Two sets of sliding blocks 404 are provided and are symmetrically arranged about the fixed block 401. Both sets of sliding blocks 404 are slidably connected to the circumferential surface of the straight rod 402. Two sets of connecting blocks 406 are provided and are fixedly installed on the bottom surface of the seat cushion 2. The two ends of the strong spring 405 are respectively fixedly installed on the opposite side surface of the limiting block 403 and the sliding block 404. The strong spring 405 is slidably connected to the circumferential surface of the straight rod 402. The two ends of the connecting rod 407 are respectively rotatably connected to the inside of the sliding block 404 and the connecting block 406. Four sets of fixed cylinders 408 are provided and are respectively fixedly installed on the surface of the vehicle body 1 and located at the bottom four corners of the seat cushion 2. The return spring 409 is fixedly installed inside the fixed cylinder 408. The buffer pad 410 is fixedly installed on the top of the return spring 409 and is fixedly connected to the bottom of the seat cushion 2.

[0025] The elastic properties of the strong spring 405 and the return spring 409 enable them to provide a certain degree of cushioning when an impact occurs. Compared with a rigid connection, the presence of the strong spring 405 and the return spring 409 makes the connection between the seat cushion 2 and the vehicle body 1 more gentle. When the stroller is vibrated, the extension and contraction of the strong spring 405 and the return spring 409 can slow down the transmission speed of the vibration, reducing the amplitude of the vibration felt by the child. The buffer pad 410, the sliding block 404, the connecting block 406, the connecting rod 407, and the strong spring 405 and the return spring 409 together form a composite shock absorption system, which can further improve the shock absorption effect and reduce the individual action of the strong spring 405 and the return spring 409, thereby reducing the discomfort caused by the rebound of the strong spring 405 and the return spring 409.

[0026] Specifically, when a child sits on the seat cushion 2, the connecting block 406 presses the sliding block 404 through the connecting rod 407. At this time, the strong spring 405 and the return spring 409 are under force. The strong spring 405 pulls the sliding blocks 404 on both sides to move on the surface of the straight rod 402. The buffer pad 410 presses the return spring 409. When the stroller encounters uneven road surfaces during travel, the strong spring 405 and the return spring 409 can play an important role in buffering. Two strong springs 405 are used and installed symmetrically, which improves stability. When the tire 301 passes over a bump or depression, the strong spring 405 and the return spring 409 will quickly compress or extend, absorbing the impact force transmitted from the road surface to the vehicle body 1, and converting the impact force from the potholes into the elastic potential energy of the spring. This can prevent the child from directly feeling strong vibrations and make them more comfortable during the ride. Example 2

[0027] Please see the appendix Figure 1 - Appendix Figure 6Furthermore, based on Embodiment 1, the anti-slip device 3 includes a connecting plate 304 and a hydraulic cylinder 305. The connecting plate 304 is connected to a tire 301 via a connecting shaft 308. The hydraulic cylinder 305 is connected to a roller 307 via a metal block 306. Two sets of connecting plates 304 are provided and fixedly installed on the front and rear sides of the bottom of the vehicle body 1, respectively. Two sets of connecting shafts 308 are provided and fixedly installed on the left and right ends between the two sets of connecting plates 304, respectively. The tire 301 is rotatably connected to the circumferential surface of one end of the connecting shaft 308. The circumferential surface of the tire 301 has a... Multiple grooves 302 and diagonal stripes 303 are arranged in a circular pattern, and several grooves 302 and diagonal stripes 303 are arranged alternately. Four sets of hydraulic cylinders 305 are provided and are fixedly installed on the bottom outer surface of the vehicle body 1. The four sets of hydraulic cylinders 305 are arranged symmetrically in the front, back, left and right. Four sets of metal blocks 306 are provided and are fixedly installed on the ends of the four sets of hydraulic cylinders 305 away from the vehicle body 1. Fixed shafts are fixedly connected between each pair of metal blocks 306. Rollers 307 are rotatably connected to the circumferential surface of the fixed shafts. Rollers 307 do not contact the tires 301 and the connecting shafts 308.

[0028] Tires 301 with grooves 302 and diagonal stripes 303 provide better handling performance. During vehicle operation, tires 301 need to constantly withstand forces from different directions, such as acceleration, braking, and turning. Tires 301 with grooves 302 and diagonal stripes 303 can better adapt to these force changes, providing better grip and stability, thereby enhancing vehicle handling performance. When turning, tires 301 with grooves 302 and diagonal stripes 303 can better grip the ground, providing greater lateral force and preventing vehicle skidding. In rainy weather or when the ground is wet, driving can only be slow. When the hydraulic cylinder 305 is activated, the roller 307 contacts the ground, increasing the contact area to prevent skidding without affecting its driving performance.

[0029] Specifically, the surface of the tire 301 is provided with multiple alternating grooves 302 and diagonal stripes 303. The grooves 302 and diagonal stripes 303 can increase the friction between the tire 301 and the ground. This creates more contact points and irregular contact surfaces when in contact with the ground, allowing for better grip and thus improving the tire 301's traction and preventing slippage. In rainy weather or when the ground is wet, the hydraulic cylinder 305 is activated to lower the roller 307 to contact the ground, increasing the contact area. Furthermore, water is squeezed between the tire 301 and the ground and discharged promptly through the grooves 302 and diagonal stripes 303, preventing the formation of a water film that reduces the friction between the tire 301 and the ground and causes the vehicle to slip.

[0030] Working principle of this utility model: This utility model is an electric children's vehicle with anti-slip and shock absorption functions. First, the child sits on the seat cushion 2. The connecting block 406 compresses the sliding block 404 through the connecting rod 407. At this time, the strong spring 405 and the return spring 409 are under force. The strong spring 405 pulls the sliding blocks 404 on both sides to move on the surface of the straight rod 402. The buffer pad 410 compresses the return spring 409. During the ride, when encountering uneven road surfaces, the strong spring 405 and the return spring 409 can play an important role in buffering. When the tire 301 passes over a bump or depression, the strong spring 405 and the return spring 409 will quickly compress or extend, absorbing the impact transmitted from the road surface to the vehicle body 1. The impact force is converted into the elastic potential energy of the spring, which can prevent children from directly feeling strong vibrations. The grooves 302 and diagonal stripes 303 can increase the friction between the tire 301 and the ground. This creates more contact points and irregular contact surfaces when in contact with the ground, which can better grip the ground and improve the grip of the tire 301, thus playing an anti-slip role. In rainy weather or when the ground is wet, the hydraulic cylinder 305 is activated to drive the roller 307 to descend and contact the ground, increasing the contact area. In addition, water will be squeezed between the tire 301 and the ground and discharged in time through the grooves 302 and diagonal stripes 303 to prevent the vehicle from skidding.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
