Description

Technical Field

[0001] This invention relates to the field of automotive ventilation equipment technology, and more specifically to an automotive seat ventilation device. Background Technology

[0002] Currently, car seats are increasingly valued by consumers. In order to improve the passenger experience of car seats, more and more functions are being designed into car seats. Seat ventilation functions that improve the air circulation environment of the parts in contact with the human body are being provided by more and more manufacturers, and the required ventilation performance is getting higher and higher.

[0003] In current ventilated seat designs and assemblies, most ventilation fans require separate mounting slots or brackets, and also necessitate the use of rubber nails, screws, and other parts to secure them. This method of fan mounting is not only complex and cumbersome, but also difficult to install, and can easily cause a foreign object sensation when passengers are seated. To address these technical problems, this invention proposes a car seat ventilation device. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a car seat ventilation device to solve the above-mentioned technical problems.

[0006] (2) Technical solution

The anti-detachment grooves are opened on the side wall of the first through hole, and a number of anti-detachment grooves are opened in the axial direction of the first through hole.

[0011] Furthermore, a first sealing mechanism is provided within the fixing mechanism.

[0012] Furthermore, the first sealing mechanism includes a first abutment rod, which is movably inserted into a locking rod, with one end of the first abutment rod abutting against the locking rod and the other end of the first abutment rod extending into a first mounting groove, which is located on the locking rod. A first support spring is wound around the first abutment rod, with both ends of the first support spring fixedly connected to the side wall of the first abutment rod and the side wall of the first mounting groove, respectively. A vertically moving plate connected to the first abutment rod is provided in the first mounting groove, and a second abutment rod is fixedly connected to the vertically moving plate. A first sealing plate is abutting against the free end of the second abutment rod. The first sealing plate is movably disposed in a second mounting groove, which is located on a ventilator. The end of the first sealing plate away from the second abutment rod is located in the first sealing groove, which is located on a ventilation device.

[0013] Furthermore, the first sealing mechanism also includes a guide reset mechanism, one end of which is fixedly connected to the first sealing plate, and the other end of which is fixedly connected to the second mounting groove.

[0014] Furthermore, the guide reset mechanism includes a guide reset rod, a guide reset cylinder, and a guide reset spring. The guide reset rod is movably inserted into the guide reset cylinder, and the guide reset spring is wound around the outside of the guide reset rod. The two ends of the guide reset spring are respectively fixedly connected to the side wall of the guide reset rod and the outer side wall of the guide reset cylinder.

[0015] Furthermore, it also includes a fastening mechanism, which includes a third abutment rod fixedly mounted on the first sealing plate, and a round cap fixedly connected to the free end of the third abutment rod. A guide block is abutting on the upper surface of the third abutment rod and the round cap, and the guide block is fixedly mounted on the side wall of the third mounting groove. The third mounting groove is opened on the ventilation device, and an inclined surface is provided on the side of the guide block away from the bottom wall of the third mounting groove.

[0016] Furthermore, it also includes a second sealing mechanism, which includes a fourth mounting groove and a fifth mounting groove formed on the first sealing plate.

The third abutment rod is movably inserted into the fourth mounting groove, and one end of the third abutment rod located in the fourth mounting groove is fixedly connected to one end of a guide limiting component. The other end of the guide limiting component is fixedly connected to the side wall of the fifth mounting groove. The upper opening and the lower opening of the fifth mounting groove are both provided with a second sealing plate, and the second sealing plate is made of an elastic material.

[0017] Furthermore, the guide limiting assembly includes a guide limiting rod, a guide limiting cylinder, and a guide limiting spring. The guide limiting rod is movably inserted into the guide limiting cylinder, and the guide limiting spring is wound around the outside of the guide limiting rod. The two ends of the guide limiting spring are respectively fixedly connected to the side wall of the guide limiting rod and the outer side wall of the guide limiting cylinder.

[0018] (3) Beneficial effects:

[0019] This invention improves the structure of existing car seat ventilation devices. The improved car seat ventilation device eliminates the need for rubber nails, screws, or other parts to fix the seat ventilation fan. This reduces the difficulty of fixing the seat ventilation fan and also avoids the feeling of foreign objects when passengers are seated, thus improving user comfort.

[0020] The fixing mechanism of this invention is used to conveniently fix the ventilation device in the mounting slot. Specifically, the ventilation device is inserted into the mounting slot. Due to the combination structure of the positioning rod and the positioning slot, the installation and docking of the mounting slot and the ventilation device can be more convenient and efficient. Furthermore, when the L-shaped hook contacts the air duct, pressing the locking rod to the right will cause the right end of the locking rod to enter the locking slot, thereby locking the positioning rod and the positioning slot together, and thus fixing the ventilation device and the seat body together. The locking rod in this invention is horizontally set, so it will not come into contact with the user in the vertical direction, thereby improving the user's comfort.

[0021] The combination structure of the anti-detachment groove and the anti-detachment protrusion provided in this invention is used to prevent the locking rod from detaching. Specifically, the combination structure of the anti-detachment groove and the anti-detachment protrusion can lock the locking rod in the first through hole, thereby locking the current position of the locking rod.

[0022] The first sealing mechanism of this invention is used to seal the ventilation device and the air duct in the vertical direction. Specifically, as the locking rod enters the locking groove to the right, it will abut against the first abutting rod and move to the right. The rightward movement of the first abutting rod will cause the second abutting rod to move to the right through the vertical moving plate. The rightward movement of the second abutting rod will abut against the first sealing plate and move to the right. The rightward movement of the first sealing plate will enter the first sealing groove, thereby achieving a seal between the air duct and the ventilation device.

[0023] The fastening mechanism provided in this invention serves to secure the L-shaped hook and the air duct more firmly. Specifically, the rightward movement of the first sealing plate causes the third abutment rod and the round cap to move to the right. The rightward movement of the third abutment rod and the round cap will abut against the inclined surface, and under the guidance of the inclined surface, will cause the guide block and the ventilation device to move upward, thereby making the L-shaped hook and the air duct more tightly connected, and thus securing the seat body and the ventilation device more firmly.

[0024] The second sealing mechanism provided in this invention is used to achieve a seal between the first sealing plate and the second mounting groove. Specifically, during the movement of the third abutment rod into the third mounting groove, it will move in the direction of the third abutment rod into the fourth mounting groove. The movement of the third abutment rod will push the gas in the fourth mounting groove into the fifth mounting groove, thereby increasing the gas pressure in the fifth mounting groove, causing the second sealing plate to expand and protrude out of the fifth mounting groove, thus achieving a seal between the first sealing plate and the second mounting groove.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 The present invention is further illustrated by the embodiments:

[0033] A car seat ventilation device includes a seat body 1. An air duct 2 is provided on the bottom plate of the seat body 1, and an installation groove 3 is provided on the air duct 2. A ventilation device 4 is provided in the installation groove 3, and the ventilation device 4 is fixed in the installation groove 3 by a fixing mechanism 5. The present invention improves the structure of the existing car seat ventilation device. The improved car seat ventilation device does not require the use of rubber nails, screws or other parts to fix the seat ventilation fan. This reduces the difficulty of fixing the seat ventilation fan and avoids the foreign object sensation when the passenger sits, thus improving the user's comfort.

[0034] In this embodiment, the fixing mechanism 5 includes an L-shaped hook 51 fixed to the ventilation device 4. The L-shaped hook 51 abuts against the air duct 2, and a positioning rod 52 is fixedly mounted on the L-shaped hook 51. The positioning rod 52 is movably inserted into a positioning groove 53, which is located on the air duct 2. A first through hole 55 is provided on the air duct 2, and a locking rod 54 is movably inserted into the first through hole 55. The locking rod 54 is movably inserted into a locking groove 56, which is located on the positioning rod 52. The fixing mechanism 5 provided in this invention is used to conveniently fix the ventilation device 4 to the mounting groove. Specifically, the ventilation device 4 is inserted into the mounting slot 3. Due to the combination structure of the positioning rod 52 and the positioning slot 53, the installation and docking of the mounting slot 3 and the ventilation device 4 are more convenient and efficient. Furthermore, when the L-shaped hook 51 contacts the air duct 2, pressing the locking rod 54 to the right will cause the right end of the locking rod 54 to enter the locking slot 56, thereby locking the positioning rod 52 and the positioning slot 53 together, and thus fixing the ventilation device 4 and the seat body 1 together. The locking rod 54 in this invention is horizontally set, so it will not contact the user in the vertical direction, thereby improving the user's comfort.

[0035] In this embodiment, the locking rod 54 is provided with a plurality of anti-detachment protrusions 58, and the anti-detachment protrusions 58 are movably disposed in the anti-detachment groove 57. The anti-detachment groove 57 is opened on the side wall of the first through hole 55, and a plurality of anti-detachment grooves 57 are opened in the axial direction of the first through hole 55. The combination structure of the anti-detachment groove 57 and the anti-detachment protrusions 58 provided in this invention is used to realize the anti-detachment of the locking rod 54. Specifically, through the combination structure of the anti-detachment groove 57 and the anti-detachment protrusions 58, the locking rod 54 can be locked in the first through hole 55, thereby locking the current position of the locking rod 54.

[0036] In this embodiment, a first sealing mechanism 6 is provided within the fixing mechanism 5. The first sealing mechanism 6 includes a first abutting rod 61, which is movably inserted into the locking rod 54. One end of the first abutting rod 61 abuts against the locking rod 54, and the other end extends into a first mounting groove 63, which is formed on the locking rod 54. A first support spring 62 is wound around the first abutting rod 61, and both ends of the first support spring 62 are fixedly connected to the side wall of the first abutting rod 61 and the side wall of the first mounting groove 63, respectively. A vertically moving plate 64 connected to the first abutting rod 61 is provided within the first mounting groove 63, and a second abutting rod 65 is fixedly connected to the vertically moving plate 64. The free end of the second abutting rod 65 abuts against a first sealing plate 67. The first sealing plate 67 is movably disposed within the second mounting groove 66, which is located on the air duct 2. The end of the first sealing plate 67 away from the second abutment rod 65 is disposed within the first sealing groove 69, which is located on the ventilation device 4. The first sealing mechanism 6 provided in this invention is used to achieve a vertical seal between the ventilation device 4 and the air duct 2. Specifically, as the locking rod 54 moves to the right into the locking groove 56, it abuts against the first abutment rod 61 and moves to the right. The rightward movement of the first abutment rod 61 causes the second abutment rod 65 to move to the right via the vertical moving plate 64. The rightward movement of the second abutment rod 65 abuts against the first sealing plate 67 and moves to the right. The rightward movement of the first sealing plate 67 enters the first sealing groove 69, thereby achieving a seal between the air duct 2 and the ventilation device 4.

[0037] In this embodiment, the first sealing mechanism 6 further includes a guide reset mechanism 68. One end of the guide reset mechanism 68 is fixedly connected to the first sealing plate 67, and the other end of the guide reset mechanism 68 is fixedly connected to the second mounting groove 66. The guide reset mechanism 68 includes a guide reset rod 681, a guide reset cylinder 682, and a guide reset spring 683. The guide reset rod 681 is movably inserted into the guide reset cylinder 682, and the guide reset spring 683 is wound around the outside of the guide reset rod 681. The two ends of the guide reset spring 683 are respectively fixedly connected to the side wall of the guide reset rod 681 and the outer side wall of the guide reset cylinder 682.

[0038] In this embodiment, a fastening mechanism 7 is also included. The fastening mechanism 7 includes a third abutment rod 71 fixedly mounted on the first sealing plate 67, and a round cap 72 is fixedly connected to the free end of the third abutment rod 71. A guide block 74 is abutting on the upper end surfaces of the third abutment rod 71 and the round cap 72, and the guide block 74 is fixedly mounted on the side wall of the third mounting groove 73. The third mounting groove 73 is opened on the ventilation device 4. An inclined surface 75 is provided on the side of the guide block 74 away from the bottom wall of the third mounting groove 73. The fastening mechanism 7 is used to fasten the L-shaped hook 51 and the air duct 2 more firmly. Specifically, the rightward movement of the first sealing plate 67 will cause the third abutment rod 71 and the round cap 72 to move to the right. The rightward movement of the third abutment rod 71 and the round cap 72 will abut the inclined surface 75 and, guided by the inclined surface 75, will cause the guide block 74 and the ventilation device 4 to move upward, thereby making the L-shaped hook 51 and the air duct 2 more tightly contacted, and thus fixing the seat body 1 and the ventilation device 4 more firmly.

[0039] In this embodiment, a second sealing mechanism 8 is also included. The second sealing mechanism 8 includes a fourth mounting groove 81 and a fifth mounting groove 82 formed on the first sealing plate 67. The fourth mounting groove 81 and the fifth mounting groove 82 are connected. The third abutment rod 71 is movably inserted into the fourth mounting groove 81, and one end of the third abutment rod 71 located in the fourth mounting groove 81 is fixedly connected to one end of a guide limiting component 83. The other end of the guide limiting component 83 is fixedly connected to the side wall of the fifth mounting groove 82. The upper opening and lower opening of the fifth mounting groove 82 are both provided with a second sealing plate 84. The second sealing mechanism 8 of this invention, made of elastic material, is used to achieve a seal between the first sealing plate 67 and the second mounting groove 66. Specifically, during the movement of the third abutment rod 71 into the third mounting groove 73, it will move in the direction of the third abutment rod 71 into the fourth mounting groove 81. The movement of the third abutment rod 71 will push the gas in the fourth mounting groove 81 into the fifth mounting groove 82, thereby increasing the air pressure in the fifth mounting groove 82, causing the second sealing plate 84 to expand and protrude out of the fifth mounting groove 82, thereby achieving a seal between the first sealing plate 67 and the second mounting groove 66.

[0040] In this embodiment, the guide limiting assembly 83 includes a guide limiting rod 831, a guide limiting cylinder 832, and a guide limiting spring 833. The guide limiting rod 831 is movably inserted into the guide limiting cylinder 832, and the guide limiting spring 833 is wound around the guide limiting rod 831. The two ends of the guide limiting spring 833 are respectively fixedly connected to the side wall of the guide limiting rod 831 and the outer side wall of the guide limiting cylinder 832.

[0041] Beneficial effects of this invention:

[0042] This invention improves the structure of existing car seat ventilation devices. The improved car seat ventilation device eliminates the need for rubber nails, screws, or other parts to fix the seat ventilation fan. This reduces the difficulty of fixing the seat ventilation fan and also avoids the feeling of foreign objects when passengers are seated, thus improving user comfort.

[0043] The fixing mechanism 5 provided in this invention is used to conveniently fix the ventilation device 4 in the mounting groove 3. Specifically, the ventilation device 4 is inserted into the mounting groove 3. Due to the combination structure of the positioning rod 52 and the positioning groove 53, the installation and docking of the mounting groove 3 and the ventilation device 4 can be more convenient and efficient. Furthermore, when the L-shaped hook 51 contacts the air duct 2, pressing the locking rod 54 to the right will cause the right end of the locking rod 54 to enter the locking groove 56, thereby locking the positioning rod 52 and the positioning groove 53 together, and thus fixing the ventilation device 4 and the seat body 1 together. The locking rod 54 in this invention is set horizontally, so it will not contact the user in the vertical direction, thereby improving the user's comfort.

[0044] The combination structure of the anti-detachment groove 57 and the anti-detachment protrusion 58 provided in this invention is used to prevent the locking rod 54 from detaching. Specifically, through the combination structure of the anti-detachment groove 57 and the anti-detachment protrusion 58, the locking rod 54 can be locked in the first through hole 55, thereby locking the current position of the locking rod 54.

[0045] The first sealing mechanism 6 provided in this invention is used to seal the ventilation device 4 and the air duct 2 in the vertical direction. Specifically, when the locking rod 54 enters the locking groove 56 to the right, it will abut against the first abutting rod 61 and move to the right. The rightward movement of the first abutting rod 61 will cause the second abutting rod 65 to move to the right through the vertical moving plate 64. The rightward movement of the second abutting rod 65 will abut against the first sealing plate 67 and move to the right. The rightward movement of the first sealing plate 67 will enter the first sealing groove 69, thereby achieving a seal between the air duct 2 and the ventilation device 4.

[0046] The fastening mechanism 7 provided in this invention is used to fasten the L-shaped hook 51 and the air duct 2 more firmly. Specifically, the rightward movement of the first sealing plate 67 will cause the third abutment rod 71 and the round cap 72 to move to the right. The rightward movement of the third abutment rod 71 and the round cap 72 will abut against the inclined surface 75, and under the guidance of the inclined surface 75, it will cause the guide block 74 and the ventilation device 4 to move upward, thereby making the L-shaped hook 51 and the air duct 2 more tightly in contact, and thus fixing the seat body 1 and the ventilation device 4 more firmly.

[0047] The second sealing mechanism 8 provided in this invention is used to achieve a seal between the first sealing plate 67 and the second mounting groove 66. Specifically, during the movement of the third abutment rod 71 into the third mounting groove 73, it will move in the direction of the third abutment rod 71 into the fourth mounting groove 81. The movement of the third abutment rod 71 will push the gas in the fourth mounting groove 81 into the fifth mounting groove 82, thereby increasing the gas pressure in the fifth mounting groove 82, causing the second sealing plate 84 to expand and protrude out of the fifth mounting groove 82, thereby achieving a seal between the first sealing plate 67 and the second mounting groove 66.
