The present disclosure relates to a cushion device applied to a child seat, the cushion device including a flexible housing and a gas accommodating space surrounded by the flexible housing. The soft shell is provided with at least one vent hole which is communicated with the gas containing space and the external space of the soft shell. The ventilation parameters of the ventilation port are matched with the external acting force applied to the soft shell, so that the buffer force matched with the external acting force is formed when the gas in the gas accommodating space is exhausted through the ventilation port.

Through set up the blow vent at soft casing and realized the intercommunication of gaseous accommodation space with the exterior space, and the parameter of ventilating of blow vent and the external force adaptation that acts on soft casing for when soft casing atress is deformed, gaseous in the gaseous accommodation space can form the cushion effect that matches with external force through the vent discharge, the cushion effect that utilizes above-mentioned exhaust process to obtain has avoided the rigid collision of outside object with children's seat, cushion effectually and further promoted the security that children took bus.

As shown in fig. 1, the present embodiment relates to a child seat 10, the child seat 10 includes a seat body 100 and a buffer device 200, and the buffer device 200 is fixedly assembled on the child seat 10. The buffer device 200 includes a flexible housing 210 and a gas accommodating space 215 surrounded by the flexible housing 210.

It should be noted that the material of the flexible housing 210 may be plastic, PVC (polyvinyl chloride), PE (polyethylene), silicone, acrylic, TPE (Thermoplastic Elastomer), TPR (Thermoplastic rubber), or other materials.

The shape of the flexible housing 210 may be a polyhedron, a sphere, an irregular shape, etc., which is not limited by the present disclosure. The flexible housing 210 may be an integrally formed structure to improve the processing convenience of the cushioning device 200 and the overall structural strength when being impacted.

As shown in fig. 2 and 4, the flexible housing 210 includes a top surface 211 and a bottom surface 212 disposed opposite to each other, and a side surface 213 connecting the top surface 211 and the bottom surface 212.

In the above embodiment, at least one vent 214 is disposed on the flexible housing 210, the vent 214 may be disposed on the side 213, and the vent 214 is used to communicate the gas accommodating space with the external space of the flexible housing 210. When the shock-absorbing device 200 receives an impact force from the outside, the gas in the receiving space does not diffuse outward all around, but is collected at the plurality of vent holes 214 provided at the side 213 of the shock-absorbing device 200 and discharged through the vent holes 214, so that the shock-absorbing device 200 obtains a shock-absorbing effect using the discharge of the gas.

The ventilation parameters of the vent 214 may include structural parameters such as the shape and size of the vent 214, and may also include other parameters such as the installation position and the ventilation direction of the vent 214. In the present embodiment, by setting and adjusting the ventilation parameters of the ventilation port 214 so that the ventilation parameters are adapted to the external force applied to the flexible housing 210, the gas in the gas accommodating space 215 can be buffered by the external force when being discharged through the ventilation port 214. In other words, when the impact absorbing device 200 is subjected to an external impact, the air vent 214 can be adapted to the external impact to achieve the impact absorbing effect. Through the arrangement, when the buffer device 200 is subjected to external impact force, the played buffer effect is not too large or too small, and the better buffer effect is realized effectively.

With continued reference to FIG. 2, the shape of the vent 214 may include a cross-shape and/or a circle. In an embodiment, the vent 214 is cross-shaped, the wall thickness of the flexible housing 210 is a first length L1, and the diameter of the cross-shaped circumcircle of the vent 214 is a second length L2, wherein the second length L2 may be greater than or equal to the first length L1, so that the flexible housing 210 can obtain a desired venting effect with a predetermined strength. For example, the second length L2 may be greater than or equal to 5 times the first length L1, so that the soft casing 210 can achieve the desired exhausting effect with a predetermined strength. When the vent holes 214 are cross-shaped, and the diameter of the cross-shaped circumcircle of the vent holes 214 is greater than or equal to 5 times the wall thickness of the flexible casing 210, the buffer device 200 can obtain a good buffer effect when being impacted.

When the cross-shaped opening is under the action of pressure, the size of the opening can be changed along with the pressure. When the external pressure received by the damper device 200 increases, the size of the opening formed by the cross-shaped structure being struck by the gas in the gas accommodating space increases. When the external pressure applied to the shock-absorbing device 200 is reduced, the size of the opening formed by the cross-shaped structure being struck by the gas in the gas-containing space is reduced.

In addition, a valve body may be disposed at the cross-shaped vent 214, and when pressure is applied, air is compressed and rapidly discharged from the air hole of the valve body, and a certain noise may be generated due to vibration. The user can make the buffer device 200 rattle by manually pressing the buffer device 200, increasing the entertainment of the buffer device 200.

It should be noted that the buffer device 200 can be reset by absorbing the external air through the vent 214 after the pressing force or impact applied to the buffer device 200 disappears.

In another embodiment, as shown in fig. 3, the vent 214 may be circular, the wall thickness of the flexible housing 210 is a first length L1, and the circular diameter of the vent 214 is a third length L3, wherein the third length L3 is greater than or equal to the first length L1, so that the flexible housing 210 can achieve the desired venting effect with a predetermined strength. For example, the third length L3 may be greater than or equal to 2 times the first length L1, so that the soft casing 210 can obtain the desired exhausting effect with the predetermined strength. When the vent 214 is circular, if the circular diameter of the vent 214 is greater than or equal to 2 times the wall thickness of the flexible housing 210, the buffer device 200 can achieve a better buffer effect when being impacted.

It should be noted that the number and distribution of vents 214 is adapted to the pressure experienced by cushioning device 200. In this embodiment, three air vents 214 of the same size and spacing may be provided on each side 213 to provide a uniform cushioning effect on each side of the cushioning device 200. Of course, in other embodiments, one, two or more vents 214 may be provided on at least one side 213, and the distribution may be adjusted accordingly. For example, when the test pressure is a first value, one vent 214 may be provided on each side 213. Three vents 214 may be provided on each side 213 when the test pressure is a second value greater than the first value. The number of vents 214 on each side 213 may be the same or different, and is not intended to be limiting in this disclosure, as may be provided according to particular cushioning requirements.

With continued reference to fig. 3, the side 213 of the cushioning device 200 includes at least one arcuate surface protruding toward the outer space of the soft housing 210. In an embodiment, when the side 213 of the buffering device 200 is an arc-shaped surface, the direction of the gas exhaust is prevented from being disordered, so that the gas in the gas accommodating space 215 is collected to the vent 214, and the buffering effect of the buffering device 200 is further improved. When the side 213 of the buffering device 200 is an arc-shaped surface, the side 213 of the flexible housing 210 can be deformed toward the outer space quickly, so as to avoid the influence of the concave surface of the flexible housing 210 toward the inner space during the air discharging process.

The sides 213 of the cushioning device 200 enclose a frame-like structure that includes arcuate transition surfaces at the corners of the frame-like structure. On one hand, the right-angle corner is prevented from stabbing a user; on the other hand, when the impact-absorbing device 200 is subjected to an impact, the arc-shaped transition surface can also rapidly deform the side surface 213 of the soft housing 210 toward the external space, so that the gas in the gas accommodating space 215 can better flow to the vent 214 of the side surface 213, rather than being collected at the corner. Through the arrangement, the buffer device 200 has a better buffer effect when being subjected to impact force.

The top surface 211 and/or the bottom surface 212 of the cushioning device 200 may include arcuate surfaces. As shown in fig. 4, in an embodiment, the bottom surface 212 is used for assembling with a child seat, the top surface 211 is used for receiving external force, the bottom surface 212 may be a flat surface for facilitating assembling, the top surface 211 may be an arc-shaped surface, the cushioning device 200 may receive external impact forces from different directions, and the arc-shaped surface is designed to have a larger force receiving surface, so as to have a better cushioning effect when the cushioning device 200 receives external impact forces from different directions.

It should be noted that, in other embodiments, the outer surface of the soft shell 210 of the buffering device 200 may also be a curved surface including a plurality of arc-shaped surfaces, or may include a plane irregular surface.

As shown in fig. 5, refer to fig. 1 as necessary. The child seat 10 includes a seat body 100 and the above-described damper 200, and the damper 200 is fixedly assembled to the child seat 10.

The communication between the gas containing space 215 and the external space is realized by arranging the vent port 214 in the soft shell 210, and the ventilation parameter of the vent port 214 is matched with the external acting force acting on the soft shell 210, so that when the soft shell 210 is deformed under stress, the gas in the gas containing space 215 can form a buffer force matched with the external acting force through the vent port 214, the hard collision between an external object and the child seat 10 is avoided by utilizing the buffer force obtained in the exhaust process, the buffer effect is good, and the safety of riding a child is further improved.

In some embodiments, the seat body 100 may include a mounting portion 110 for coupling with the cushioning device 200. The child seat 10 further includes a wall breaking structure 120, the wall breaking structure 120 is disposed on the mounting portion 110 and located at the bottom of the buffering device 200, and when the acting force applied to the soft shell 210 is greater than a predetermined value, the wall breaking structure 120 pierces the soft shell 210. When the impact force applied to the buffering device 200 is greater than the predetermined value, the gas in the gas accommodating space is exhausted through the vent 214, and the wall-broken structure 120 may puncture the buffering device 200 to provide further buffering protection.

As shown in fig. 5, refer to fig. 1 as necessary. The seat body 100 includes a first outer side 130 corresponding to a head position, and at least one cushion device 200 is fixedly assembled to the first outer side 130. In the present embodiment, the buffering device 200 is fixed on the first outer side 130 corresponding to the head position of the child seat 10, so that when the automobile runs into an emergency, the buffering device 200 can rapidly exhaust air through the vent 214, and the head of the child on the seat can be protected by the buffering device 200 to avoid injury.

In other embodiments, the cushioning device 200 can be secured to other locations of the child seat, such as the buttocks, the back, or the interior of the child seat.

In the above embodiment, the connection manner of the shock absorber 200 and the mounting portion 110 of the child seat 10 may be snap-fit, adhesive, or the like. Also, the number of the buffer devices 200 may be one or more, and the present disclosure does not limit this.

The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
