Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seat accessories, and in particular relates to a pneumatic ECU quick-insertion structure for an automobile seat. Background Art

[0002] The pneumatic ECU in an automotive seat controls the inflation and exhaust of airbags in systems such as the car seat's massage and support systems. It connects to each airbag via multiple air pipes. As massage and support systems utilize an increasing number of airbags to achieve optimal massage and support effects, the demand for the number of air pipes that can be connected to the pneumatic ECU is also increasing.

[0003] Currently, the mainstream method for connecting air pipes to pneumatic ECUs is to set up quick plugs on the ECU box body. In this way, the air pipes can be directly plugged into the quick plugs for a secure connection, which also improves assembly efficiency. However, the current quick plugs are all attached to the EUC box body. Each quick plug must have a snap-on structure. In this way, in the assembly of the quick plug and EUC box body, the snap-on structure of the quick plug needs to take up a certain amount of space, making the assembly of the quick plug and EUC box body larger. When a large number of air pipes need to be connected, the assembly of the quick plug and EUC box body is too large to be installed in the car seat. Utility Model Content

[0004] The purpose of the utility model is to provide a quick-plug structure for a pneumatic ECU of an automobile seat, so as to solve the technical problem that the assembly of the quick plug and the EUC box body is bulky because the quick plug is attached to the EUC box body and an additional clamping structure is required.

[0005] In order to solve the above technical problems, the utility model provides a car seat pneumatic ECU quick-plug structure, including: a slot, which is opened on the ECU lower shell; a plurality of sockets, which are arranged at intervals in the slot; a plurality of tubular protrusions, which are arranged in the slot and are concentric with a socket respectively; a lower sealing ring is inserted in the gap between each socket and the tubular protrusion with an interference fit, and the lower sealing ring is connected to an upper sealing ring; an ECU upper shell, on which a hole corresponding to each socket is opened, so that each hole is concentric with the corresponding socket when the ECU lower shell is closed; a plurality of air pipe plugs, one end of which has a groove corresponding to the upper sealing ring, so that after being inserted into the hole, it is interference fit with the corresponding upper sealing ring.

[0006] Furthermore, the lower sealing rings are connected to form a sealing strip, so that when plugged into the socket, the bottom surface of the sealing strip abuts against each of the tubular protrusions; and a tightening protrusion is provided at the inner opening of each jack of the ECU upper shell, so as to press on the top surface of the sealing strip when the ECU lower shell is closed.

[0007] Furthermore, the socket is in the shape of a conical bottle; the opening of the lower sealing ring is provided with a lower fitting chamfer; the opening of the upper sealing ring is provided with an upper fitting chamfer; the rod head of the rod inserted into the groove formed by the groove on the tracheal plug is in the shape of a conical bottle.

[0008] Furthermore, a plurality of the tracheal plugs are connected to form a plug block.

[0009] Furthermore, the number of tracheal plugs in the plug block is one, two, three, four or five.

[0010] Furthermore, the plug block is provided with buckles; and the ECU upper shell is provided with buckle grooves corresponding to the buckles.

[0011] Furthermore, a joint barb is provided at the other end of the tracheal plug.

[0012] The beneficial effect of the present invention is that it aims to solve the technical problem that the quick plug and the EUC case need to be additionally provided with a clamping structure because the quick plug is externally attached to the EUC case, resulting in a large volume of the assembly of the quick plug and the EUC case. The present automobile seat pneumatic ECU quick-plug structure utilizes the certain space required in the height direction of the EUC case. The present automobile seat pneumatic ECU quick-plug structure utilizes the certain space required in the height direction of the EUC case, provides a slot on the ECU lower shell, and provides a socket and a tubular protrusion in the slot. The lower sealing ring and the upper sealing ring thereon are plugged into the socket. After the ECU upper shell is covered with the ECU lower shell, the upper sealing ring is exposed through the insertion hole, so that the tracheal plug can be directly plugged into the upper sealing ring through the groove. That is, the plugging structure required for the tracheal plug is built into the certain space required in the height direction of the EUC case. The tracheal plug no longer needs to be additionally provided with a clamping structure, and can be inserted into the EUC case, thereby reducing the volume of the assembly of the tracheal plug and the EUC case.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments that can be realized by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example

[0025] like Figure 1 As shown, the utility model provides a car seat pneumatic ECU quick plug structure, comprising: a slot 100, which is opened on the ECU lower shell 210; a plurality of sockets 300, which are spaced apart and arranged in the slot 100; Figure 2 , a plurality of tubular protrusions 400, which are arranged in the slot 100 and are concentric with a socket 300 respectively; Figure 3, a lower sealing ring 510 is inserted into the gap between each socket 300 and the tubular protrusion 400 by interference fit, and the lower sealing ring 510 is connected to the upper sealing ring 520; the ECU upper housing 220 is provided with a socket 221 corresponding to each socket 300, so that each socket 221 is concentric with the corresponding socket 300 when the ECU lower housing 210 is closed; combined Figure 4 , a plurality of tracheal plugs 600 , one end of which is provided with a groove 610 corresponding to the upper sealing ring 520 , so as to interference fit with the corresponding upper sealing ring 520 after being inserted into the insertion hole 221 .

[0026] The present automotive seat pneumatic ECU quick-connect structure utilizes the required height space of the EUC housing. A slot 100 is provided on the ECU lower housing 210. A socket 300 and a tubular protrusion 400 are provided within the slot 100. The lower sealing ring 510 and the upper sealing ring 520 thereon are plugged into the socket 300. After the ECU upper housing 220 covers the ECU lower housing 210, the upper sealing ring 520 is exposed through the insertion hole 221, allowing the tracheal plug 600 to be directly plugged into the upper sealing ring 520 through the groove 610. In other words, the plugging structure required for the tracheal plug 600 is built into the required height space of the EUC housing. The tracheal plug 600 can be inserted into the EUC housing without the need for an additional snap-fit ​​structure, thereby reducing the volume of the assembly of the tracheal plug 600 and the EUC housing.

[0027] like Figure 2 As shown, each lower sealing ring 510 is connected to form a sealing strip 530, combined with Figure 5 and Figure 6 , so that when plugged into the socket 300, the bottom surface of the sealing strip 530 abuts against each of the tubular protrusions 400; Figure 4 As shown, a pressing protrusion 222 is provided at the inner opening of each jack 221 of the ECU upper housing 220 to press on the top surface of the sealing strip 530 when the ECU lower housing 210 is closed. In at least one embodiment, the pressing protrusion 222 is cylindrical. It should be noted that the pressing protrusion 222 can also be in the shape of a convex block, an arc segment or a strip, as long as it can press the sealing strip 530. The sealing ring 510 is connected to form a sealing strip 530, which can be clamped between the ECU lower housing 210 and the ECU upper housing 220, so that the lower sealing ring 510 is more tightly combined with the socket 300 and is not easy to loosen.

[0028] like Figure 6As shown, in at least one embodiment, the socket 300 may be in the shape of a conical flask; the opening of the lower sealing ring 510 may be provided with a lower fitting chamfer 511, thereby enabling the lower sealing ring 510 to be smoothly inserted into the socket 300 and fully fit the socket 300, improving sealing performance; the opening of the upper sealing ring 520 may be provided with an upper fitting chamfer 521, and the rod head of the rod 630 inserted into the groove formed by the groove 610 on the tracheal plug 600 may be in the shape of a conical flask, thereby enabling the tracheal plug 600 to be smoothly inserted into the upper sealing ring 520 and fully fit the upper sealing ring 520, improving sealing performance.

[0029] like Figure 5 As shown, several air pipe plugs 600 of the present automotive seat pneumatic ECU quick-connect structure are connected to form a plug block 700. This allows the air pipes converging to the pneumatic ECU to be grouped according to the function of the airbag they connect to, for example. Air pipes connecting to airbags with the same function can be connected to the same plug block 700, achieving a grouping effect and facilitating identification during assembly.

[0030] like Figure 5 and Figure 7 As shown, the number of tracheal plugs 600 in the plug row block 700 is one, two, three, four, or five, thereby forming one row, two rows, three rows, four rows, and five rows, each specifically used to connect a specific trachea, making it easier to identify during assembly.

[0031] like Figure 4 、 Figure 1 and Figure 7 As shown, the plug block 700 may be equipped with latches 710; the ECU upper housing 220 has latch slots 223 corresponding to the latches 710. When the plug block 700 is inserted to its limit, the latches 710 engage with the latch slots 223, tightening the connection between the tracheal plug 600 and the upper sealing ring 520. To remove the plug block 700, firmly pinch the latches 710 and pull it out.

[0032] like Figure 4 As shown, the other end of the tracheal plug 600 is equipped with a connector barb 620 for quick insertion of the trachea. It should be noted that a channel is formed on the insertion rod 630 in the slot of the tracheal plug 600, which leads to the other end with the connector barb 620. The socket 300 also has a channel that connects to the ventilation hole in the ECU lower housing 210, thereby connecting the trachea inserted into the connector barb 620 to the pneumatic ECU.

[0033] In summary, the present automobile seat pneumatic ECU quick-plug structure utilizes the certain space required by the EUC box in the height direction, provides a slot 100 on the ECU lower shell 210, and provides a socket 300 and a tubular protrusion 400 in the slot 100. The lower sealing ring 510 and the upper sealing ring 520 thereon are plugged into the socket 300. After the ECU upper shell 220 covers the ECU lower shell 210, the upper sealing ring 520 is exposed through the insertion hole 221, so that the tracheal plug 600 can be directly plugged into the upper sealing ring 520 through the groove 610. That is, the plug-in structure required by the tracheal plug 600 is built into the certain space required by the EUC box in the height direction. The tracheal plug 600 no longer needs to be provided with an additional snap-on structure and can be inserted into the EUC box, thereby reducing the volume of the assembly of the tracheal plug 600 and the EUC box.
