Description

Technical Field

[0001] The present application relates to the field of electric vehicles, and in particular to a safety seat cushion and a children's electric vehicle. Background Art

[0002] Two-wheeled electric vehicles are a modern conventional means of transportation, and with the development of technology, electric technology has been applied to the field of children's vehicles.

[0003] At present, electric vehicles for children generally include a frame, a driving battery arranged on the frame, and wheels arranged at both ends of the frame. A seat cushion for children to sit on is usually installed on the top of the frame, and the seat cushion generally includes a seat cushion bracket and a seat cushion cover covering the seat cushion bracket. The top of the seat cushion is usually a horizontal surface.

[0004] With regard to the above-mentioned related technologies, when children are riding, since the seat cushion is flat, the children are easily driven off the seat cushion by the inertia generated by sudden braking, resulting in the children falling off the vehicle, etc., so the safety performance of the seat cushion needs to be improved. Utility Model Content

[0005] In order to improve the safety performance of the seat cushion, the present application provides a safety seat cushion.

[0006] The safety seat cushion provided in this application adopts the following technical solution:

[0007] A safety seat cushion comprises a connecting frame fixedly connected to the top of an electric vehicle frame, a seat cushion frame fixedly arranged on the connecting frame, and a seat cushion cover sleeved on the seat cushion frame, wherein the seat cushion frame is provided with a protruding portion extending upwardly and obliquely at one end away from the handlebars of the electric vehicle, and the connecting frame is provided with an inclined supporting portion supporting the protruding portion.

[0008] By adopting the above technical solution, when the electric vehicle suddenly brakes or encounters bumps, the design of the raised part increases the friction between the child and the seat cushion, which can reduce the backward movement of the child's body due to inertia, thereby improving riding safety to a certain extent. The stable support of the raised part by the inclined support part not only enhances the overall structural strength of the seat cushion frame, but also ensures the stability of the seat cushion during riding, reducing the impact on riding experience and child safety due to looseness or deformation of the seat cushion.

[0009] Optionally, the connecting frame includes at least one connecting plate and a support plate located on the top of the connecting plate, the inclined support portion is located at the end of the support plate, the connecting plate is plugged into the support plate, and the cross-sections of the connecting frame and the frame are triangular.

[0010] By adopting the above technical solution, the connecting frame adopts the design of at least one connecting plate and a supporting plate, and is combined by plugging. This structure not only simplifies the assembly process, but also enhances the overall strength of the connecting frame. In particular, when the cross-section of the connecting frame and the frame is triangular, the entire cushion system can withstand greater loads and impacts due to the stability of the triangle, and the plug-in connection method also makes the installation and removal of the connecting frame simple and easy, which not only reduces the installation cost, but also facilitates future maintenance and replacement work.

[0011] Optionally, the support plate is symmetrically provided with first extension parts on both sides along the length direction, and the centers of the first extension parts are each provided with a first positioning hole for screwing the seat cushion frame.

[0012] By adopting the above technical solution, since the first extension parts are symmetrically arranged on both sides of the support plate along the length direction, the contact area between the seat cushion frame and the connecting frame is increased, making the connection between the two more secure; the screws fix the seat cushion frame to the support plate through the first positioning hole, effectively preventing the seat cushion from shaking or shifting during riding, thereby improving the riding stability.

[0013] Optionally, the support plate is provided with a second extending portion near the inclined supporting portion, and an extending direction of the second extending portion is consistent with an extending direction of the first extending portion.

[0014] By adopting the above technical solution, the addition of the second extension further strengthens the structural strength of the support plate, so that the support plate forms a stable support structure, which further improves the connection stability between the seat frame and the connecting frame. In addition, when the seat is subjected to external force, the stable connection structure can reduce the shaking of the seat frame, ensuring the safety of children when riding.

[0015] Optionally, plug-in blocks are provided at both ends of the top of the connecting plate, and plug-in interfaces matching the plug-in blocks are provided on the supporting plate.

[0016] By adopting the above technical solution, the design of the plug-in block and the plug-in interface makes the connection between the connecting plate and the supporting plate simple and quick. During installation, it is only necessary to align the plug-in block with the plug-in interface and insert it, without the need for additional fixings or complicated operation steps, thereby greatly simplifying the installation process and improving the installation efficiency.

[0017] Optionally, the inclined support portion is inclined 10-20 degrees in a direction away from the electric frame.

[0018] By adopting the above technical solution, the inclination angle of the inclined support part can better fit the back and hip curves of the rider, making the sitting posture more natural and comfortable, and reducing the fatigue caused by long-term riding.

[0019] Optionally, reinforcement holes are provided at the central portion of the connecting plates.

[0020] By adopting the above technical solution, the design of the reinforcement hole enables the connecting plate to more effectively disperse and resist external forces when subjected to stress, and the material around the reinforcement hole will bear more stress, thereby improving the overall structural strength of the connecting plate and making the connecting plate less likely to deform or break when subjected to impact or vibration.

[0021] Optionally, the seat cushion frame is provided with a pre-fixing groove for inserting the inclined supporting portion of the connecting plate, and the bottom wall of the pre-fixing groove is also provided with a second positioning hole for installing a screw.

[0022] By adopting the above technical solution, the pre-fixing grooves provided on the seat frame provide a precise insertion position for the inclined support part of the connecting frame, making the installation process more convenient and quick; at the same time, the pre-fixing grooves can also limit the movement of the inclined support part to a certain extent, making it easier to install the seat frame. In addition, fixing the inclined support part to the seat frame with screws also improves the installation efficiency.

[0023] Optionally, the edge of the seat cushion frame is provided with reinforcing ribs, and the inner side of the seat cushion cover is provided with snap-in grooves corresponding to the reinforcing ribs.

[0024] By adopting the above technical solution, the design of the reinforcing ribs improves the rigidity and load-bearing capacity of the seat frame, and by increasing the support points at the edge of the seat frame, the pressure on the seat cushion during use is dispersed, thereby reducing the probability of deformation and damage of the seat frame, which helps to extend the service life of the seat cushion and improve the durability of the product. In addition, the snap-in grooves arranged on the inner side of the seat cushion cover correspond to the reinforcing ribs, so that the seat cushion cover can be more easily installed on the seat cushion frame.

[0025] Optionally, a children's electric vehicle includes a frame, a front wheel and a rear wheel arranged at both ends of the frame, a handle arranged at the top of the frame and close to the front wheel, and a driving member, including the above-mentioned safety cushion, and the safety cushion is arranged on the top of the frame.

[0026] By adopting the above technical solution, since a safety seat cushion is installed on the children's electric vehicle, a better buffering and shock absorption effect is provided, which reduces the occurrence of children falling backward due to inertia caused by sudden braking.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Since the seat frame is provided with a protrusion extending obliquely upward at one end away from the handlebar of the electric vehicle, and the connecting frame is provided with an inclined support portion supporting the protrusion, when the electric vehicle suddenly brakes or encounters bumps, the design of the protrusion increases the friction between the child and the seat, which can reduce the backward movement of the child's body due to inertia, thereby improving riding safety to a certain extent.

[0029] The cushion frame is provided with a pre-fixing groove for inserting the inclined support part of the connecting frame, and the bottom wall of the pre-fixing groove is also provided with a second positioning hole for screw installation. The pre-fixing groove provided on the cushion frame provides a precise insertion position for the inclined support part of the connecting frame, making the installation process more convenient and quick. At the same time, the pre-fixing groove can also limit the movement of the inclined support part to a certain extent, making it easier to install the cushion frame. In addition, fixing the inclined support part to the cushion frame with screws also improves the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
