[0001] The present disclosure relates to the technical field of safety seats, and in particular to a ventilation pad and a ventilation mechanism for a safety seat. Background Art

[0002] A child seat, also known as a child restraint system, is a seat designed for children of different ages (or weights), installed in a car, and can effectively improve the safety of children riding in a car. The European regulation ECE R129 defines a child safety seat as: a child safety protection system that can be fixed to a motor vehicle and consists of a seat belt assembly or flexible components, adjustment mechanisms, accessories, etc. It can be combined with additional devices such as a portable crib, infant carrier, auxiliary seat or collision protection device. It can reduce the impact force on children and limit their body movement in the event of a car collision or sudden deceleration to reduce injuries to them, ensuring the safety of children riding in a car. It is widely used.

[0003] With the development of society, the role of safety seats is no longer limited to protecting children's safety. Various functional safety seats are becoming more and more popular among the public. In real life, people often encounter that in the hot summer, when children are placed in safety seats, they are prone to sweating and crying. In order to solve this problem, the safety seats in the prior art are usually provided with ventilation pads, which are connected to blowers or fans to play the role of ventilation and heat dissipation. However, due to the internal structural problems of the ventilation pads on the market, the air volume of the air outlets at different positions on the surface of the ventilation pads often differs greatly, which makes the places with large air volume of the ventilation pads cooler, and the places with small air volume are still hot, which brings a bad experience to users. Utility Model Content

[0004] In view of the deficiencies or problems existing in the prior art, the present invention provides a ventilation cushion for a safety seat, which has a simple structure and good ventilation effect.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a ventilation cushion for a safety seat, including a seat cushion, a ventilation plate is arranged in the seat cushion, the ventilation plate is provided with a ventilation cavity, a plurality of first ventilation holes are arranged on the seat cushion, a plurality of second ventilation holes are arranged on the ventilation plate, the positions of the first ventilation holes and the second ventilation holes correspond to each other, the ventilation plate is detachably connected with a ventilation duct, the ventilation duct is connected with a fan, wind enters the ventilation duct under the action of the fan, the ventilation duct is connected with the ventilation cavity, the wind enters the ventilation cavity through the ventilation duct, and then flows out from the first ventilation hole.

[0006] As a preferred embodiment, the ventilation plate includes a first shell and a second shell, the first shell and the second shell are injection molded, and after the first shell and the second shell are connected, a ventilation cavity is formed inside the ventilation plate, and the second ventilation hole is arranged on the first shell.

[0009] As a preferred embodiment, the diameter of the first connecting head is larger than the sum of the diameters of the multiple second ventilation holes, and the diameter of the first ventilation hole is larger than the diameter of the second ventilation hole. Such a setting can form a certain pressure in the ventilation cavity, enhance the fluidity of the gas in the seat cushion, and make the air output of the first ventilation hole more uniform, thereby having a better cooling effect.

[0010] Compared with existing products, since the ventilation plate is provided with a ventilation cavity, wind enters the ventilation duct under the action of the fan, the ventilation duct is connected with the ventilation cavity, and the wind enters the ventilation cavity from the ventilation duct. After entering the ventilation cavity, the wind can be better diffused under the action of pressure, and the wind in the ventilation cavity flows out evenly from the first ventilation hole, thereby avoiding uneven air output from the ventilation pad.

[0011] Another object of the present disclosure is to provide a ventilation mechanism for a safety seat, comprising the ventilation pad described above and at least one ventilation duct, one end of the ventilation duct being connected to a first connector, the other end of the ventilation duct being connected to a fan, and a support member being arranged in the ventilation duct.

[0015] As a preferred implementation, the fan is a centrifugal fan, and the fan is connected to a switch.

[0016] Compared with existing products, since support members are provided in the ventilation duct, the support members are used to support the ventilation duct to prevent the ventilation duct from deforming when subjected to external force, thereby affecting the normal air intake and wind speed of the ventilation duct, making the structure of the ventilation mechanism more stable and the operation more reliable.

Therefore, the above terms should not be understood as limiting the present invention.

[0029] Please see Figure 1 to Figure 6 As shown, an embodiment of the present disclosure provides a ventilation cushion for a safety seat, including a seat cushion 1, which is detachably connected to the seat, a ventilation plate is provided in the seat cushion 1, the ventilation plate is provided with a ventilation cavity 8, a plurality of first ventilation holes 2 are provided on the seat cushion 1, a plurality of second ventilation holes 7 are provided on the ventilation plate, the positions of the first ventilation holes 2 and the second ventilation holes 7 correspond to each other, the ventilation plate is detachably connected with a ventilation duct 3, the ventilation duct 3 is connected with a fan, wind enters the ventilation duct 3 under the action of the fan, the ventilation duct 3 is connected with the ventilation cavity 8, the wind enters the ventilation cavity 8 from the ventilation duct 3, and then flows out from the first ventilation hole 2. Specifically, the ventilation plate and the cushion 1 are insert-type foaming molding, the product has good performance and short molding cycle, the number and position of the first ventilation holes 2 correspond to the number and position of the second ventilation holes 7, the fan is connected with a switch, and the switch is used to control the start and stop of the fan. The fan here is a centrifugal fan, which is a driven fluid machine. It relies on the input mechanical energy to increase the gas pressure and discharge the gas. The centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, and then decelerate and change the flow direction to convert kinetic energy into potential energy. The ventilation cavity 8 is a cavity formed inside the ventilation plate, and the cavity is connected to the second ventilation hole 7. The wind enters the ventilation duct 3 under the action of the fan, and the ventilation duct 3 is connected to the ventilation cavity 8. The wind enters the ventilation cavity 8 from the ventilation duct 3. After entering the ventilation cavity 8, the wind can be well diffused under the action of pressure to fill the entire ventilation cavity 8, and the wind in the ventilation cavity 8 flows out evenly from the first ventilation hole 2, thereby avoiding the uneven air flow of the ventilation pad.

[0030] Please see Figure 6As shown, in one embodiment of the present disclosure, the ventilation plate includes a first shell 11 and a second shell 12, which are injection molded. After the first shell 11 and the second shell 12 are connected, a ventilation cavity 8 is formed inside the ventilation plate, and a second ventilation hole 7 is provided on the first shell 11. The first shell 11 and the second shell 12 are both made of plastic, and the material of the seat cushion 1 is any one of memory foam, sponge, artificial cotton, and foam particles. Since the ventilation plate is provided in the seat cushion 1, the ventilation plate does not directly contact the human body, and the seat cushion 1 contacts the human body. The material of the seat cushion 1 is set to a soft material, and people will feel more comfortable sitting on it. At the same time, a plurality of first ventilation holes are provided on the seat cushion 1 to ensure ventilation and heat dissipation of the seat cushion 1. The ventilation plate is arranged inside the seat cushion 1. On the one hand, the ventilation plate plays a supporting role to prevent the seat cushion 1 from slight deformation due to long-term use. On the other hand, a ventilation cavity 8 is constructed inside the ventilation plate, and a second ventilation hole 7 is arranged on the ventilation plate. Wind first enters the ventilation cavity 8 through the ventilation duct 3 and then flows out through the first ventilation hole 2. The ventilation cavity 8 plays a collecting role, and the wind is collected in the ventilation cavity 8 and then flows out evenly through multiple first ventilation holes 2, so that the ventilation volume of the seat cushion 1 is more uniform and the wind speed is more stable.

[0031] Further, such as Figure 3 to Figure 5 As shown, at least one first connector 6 for connecting the ventilation duct 3 is provided on the side of the ventilation plate, and the first connector 6 is also the air inlet of the ventilation cavity 8. At least one mounting opening 13 is provided on the side of the cushion 1, and the first connector 6 passes through the mounting opening 13. Specifically, a convex ridge 9 is provided on the first connector 6, and a slot 10 is provided at the mounting opening 13. The convex ridge 9 cooperates with the slot 10 to limit the first connector 6 at the mounting opening 13. Preferably, the cushion 1 includes two legs 5 and a back 4, and the legs 5 and the back 4 are both provided with first ventilation holes 2. The mounting opening 13 is provided at the connection between the legs 5 and the back 4. Such a setting makes the mounting opening 13 approximately located in the middle position of the cushion 1, and the first connector 6 is also approximately located in the middle position of the ventilation plate, so that the wind can diffuse faster and more evenly throughout the ventilation cavity 8 when entering the ventilation cavity 8 again, so as to ensure that the ventilation volume of each first ventilation hole 2 is more uniform and the wind speed is more stable. It should be noted that the number of the first connecting heads 6 and the mounting ports 13 can be one or two, and the number of the two remains consistent. If two first connecting heads 6 and two mounting ports 13 are set, the two first connecting heads 6 are respectively arranged on both sides of the ventilation plate, and the two mounting ports 13 are respectively arranged on both sides of the seat cushion 1, then each first connecting head 6 is respectively connected to the ventilation duct 3.

[0032] Furthermore, the diameter of the first connecting head 6 is larger than the sum of the diameters of the multiple second ventilation holes 7, and the diameter of the first ventilation hole 2 is larger than the diameter of the second ventilation hole 7. Such a setting can form a certain pressure in the ventilation cavity 8, which can enhance the fluidity of the gas in the seat cushion 1, and also make the air output of the first ventilation hole 2 more uniform, thereby having a better cooling effect.
