Detailed Description

In order to make the technical scheme of the present application better understood by those skilled in the art, the technical scheme of the present application will be further described in detail with reference to the accompanying drawings and the detailed description.

The application provides a leg support device of an automobile seat and the automobile seat comprising the leg support device.

As shown in fig. 1 to 4, the leg rest apparatus provided by the present application includes a swing mechanism 100, an electric drive mechanism 300, a telescopic mechanism 200, and a cable mechanism 400.

The electric driving mechanism 300 is in transmission connection with the swing mechanism 100, so that the swing mechanism 100 can be driven to swing back and forth. The telescopic mechanism 200 is slidably connected to the swing mechanism 100, and can be telescopic with respect to the swing mechanism 100.

The cable mechanism 400 includes a cable 401. One end of the cable 401 is connected to the frame a of the car seat to become a fixed end. Specifically, a cable fixing bracket 403 may be provided, the fixed end of the cable 401 is connected to the cable fixing bracket 403, the cable fixing bracket 403 is connected to the framework a of the car seat, and specifically, the cable fixing bracket 403 may be connected to the lower part of the framework a of the car seat (see fig. 5). The other end of the cable 401 is connected to the telescopic mechanism 200 to become a movable end. A region between the fixed end and the movable end of the cable 401 is in contact with the swing mechanism 100.

Since a certain area between the fixed end and the movable end of the cable 401 is in contact with the swing mechanism 100, and the swing mechanism 100 can swing back and forth under the drive of the electric drive mechanism 300, the position of the contact area between the swing mechanism 100 and the cable 401, hereinafter referred to as the contact area, moves forward or backward as the swing mechanism 100 swings back and forth.

The position of the contact area moves forward or backward, which causes the length of the cable 401 between the contact area and the fixed end and the movable end to change, and since the total length of the cable 401, that is, the length of the cable 401 between the fixed end and the movable end is not changed, if the length of the cable 401 between the contact area and the fixed end is long, the length of the cable 401 between the contact area and the movable end is short, whereas if the length of the cable 401 between the contact area and the fixed end is short, the length of the cable 401 between the contact area and the movable end is long.

Since the contact area of the cable 401 is in contact with the swing mechanism 100, the movable end of the cable 401 is connected with the telescopic mechanism 200, and the telescopic mechanism 200 is slidably connected with the swing mechanism 100, when the length of the cable 401 between the contact area and the movable end becomes shorter or longer, the telescopic mechanism 200 is forced to slide relative to the swing mechanism 100, so that the telescopic mechanism 200 is extended or retracted relative to the swing mechanism 100.

In a specific application, as shown in fig. 5 and 6, the cable fixing bracket 403 may be connected below the framework a of the car seat. When the leg support device is needed, the electric driving mechanism 300 is used for driving the swing mechanism 100 to swing forwards, and the telescopic mechanism 200 is driven to extend out through the stay rope mechanism 400 when the swing mechanism 100 swings forwards, so that the leg support device extends to the front of the framework A of the automobile seat, and the leg support device has a supporting effect on the legs of passengers. When the leg rest device is not used, the electric driving mechanism 300 is used for driving the swing mechanism 100 to swing backwards, and when the swing mechanism 100 swings backwards, the telescopic mechanism 200 is driven to retract through the stay rope mechanism 400, so that the leg rest device is contained below the framework A of the automobile seat.

As can be seen from the above description, in the leg rest apparatus, the electric driving mechanism 300 is used to drive the swing mechanism 100 to swing back and forth, and when the swing mechanism 100 swings back and forth, the cable mechanism 400 drives the telescopic mechanism 200 to stretch and retract, so that one set of electric driving mechanism 300 simultaneously realizes two actions of rotation and stretching, and compared with two sets of electric driving mechanisms 300, the whole volume, cost and weight of the leg rest apparatus are reduced. In addition, the leg rest device is driven by the cable mechanism 400, and the cable mechanism 400 has the characteristics of small volume, low cost and light weight, so that the whole volume, cost and weight of the leg rest device are reduced more conveniently.

In one embodiment, as shown in fig. 1, the leg rest apparatus includes an elastic restoring member 500, where the elastic restoring member 500 is connected to the telescopic mechanism 200 and the swing mechanism 100, and the elastic restoring member 500 provides an elastic restoring force for restoring the telescopic mechanism 200 from the extended state to the retracted state.

In order for the cable mechanism 400 to achieve the above-described transmission, it is necessary to secure the overall length of the cable 401, that is, the length of the cable 401 between the fixed end and the movable end, to be constant, and thus the cable 401 itself is not elastic. Since the cable 401 itself is not elastic, if the telescopic mechanism 200 is reset from the extended state to the retracted state by only pulling of the cable 401, the recovery process is slow, affecting the user experience. The elastic restoring member 500 can solve the problem, and the telescopic mechanism 200 can be quickly restored to the retracted state and stabilized in the retracted state.

In one embodiment, as shown in fig. 2, the swing mechanism 100 includes two swing brackets 101 disposed at a left-right interval, a lower swing beam 103 and an upper swing beam 102 connected between the two swing brackets 101. By the design, the swing mechanism 100 is of a frame structure, so that the swing mechanism is high in strength, small in size and light in weight. Specifically, the connection form of the two swing brackets 101 and the lower swing beam 103 and the connection form of the two swing brackets 101 and the upper swing beam 102 are not limited, and may be an assembly connection such as a clamping connection, a fastening connection, or the like, or may be an integral molding.

In one embodiment, as shown in fig. 3, the telescopic mechanism 200 includes two telescopic supports 201 disposed at a left-right interval, and an upper telescopic beam 202 and a lower telescopic beam 203 connected between the two telescopic supports 201. By the design, the telescopic mechanism 200 is of a frame structure, so that the telescopic mechanism is high in strength, small in size and light in weight. Specifically, the connection form of the two telescopic brackets 201 and the lower telescopic cross beam 203 and the connection form of the two telescopic brackets 201 and the upper telescopic cross beam 202 are not limited, and may be assembled connection such as clamping connection, fastening connection, and the like, or may be integrally formed, and in the figure, the lower telescopic cross beam 203 is connected below the two telescopic brackets 201 through the mounting bolt 204.

In one embodiment, telescoping mechanism 200 is connected between two swing brackets 101 of swing mechanism 100. By the design, the telescopic mechanism 200 and the swing mechanism 100 are compact, and the whole volume of the leg rest device is reduced.

Of course, the structure and the relative positional relationship of the swing mechanism 100 and the telescopic mechanism 200 are not limited to the above description, as long as both are ensured to have certain supporting strength and are capable of being slidingly connected with each other.

In one embodiment, as shown in fig. 4, the swing mechanism 100 includes a friction member 104, where the friction member 104 is made of a wear-resistant material. The friction member 104 is detachably mounted on the swing bracket 101, and in the figure, the friction member 104 is fixedly connected with the swing bracket 101 through a friction member fixing bolt 105 and a friction member fixing nut 106. The telescopic bracket 201 is slidably connected to the friction member 104. By the design, when the telescopic bracket 201 slides, friction is mainly generated between the telescopic bracket and the friction piece 104, so that abrasion of the swing bracket 101 is not easy to be caused, and only the friction piece 104 needs to be replaced during subsequent maintenance, so that the maintenance cost is low.

In one embodiment, as shown in fig. 4, the upper end of the elastic restoring member 500 is connected with the upper swing beam 102, the lower end of the elastic restoring member 500 is connected with the lower telescopic beam 203, and the upper swing beam 102 and the lower telescopic beam 203 are used as mounting bases of the elastic restoring member 500, so that after the elastic restoring member 500 is mounted, the elastic restoring member 500 is located in the frame of the swing mechanism 100, so that the elastic restoring member 500 and the swing mechanism 100 are compact, and the overall size of the leg rest device is reduced more advantageously.

In one embodiment, the movable end of the cable 401 is connected to the upper telescopic beam 202, the cable 401 contacts the lower swing beam 103, the swing mechanism 100 swings back to the limit position and the telescopic mechanism 200 contracts to the limit position as shown in fig. 1, and the cable 401 extends from the fixed end to the movable end: extending downward and forward around the lower swing beam 103 and then upward to the upper telescoping beam 202. By the design, the arrangement space occupied by the inhaul cable 401 is smaller, the whole volume of the leg support device is more favorably reduced, and the telescopic mechanism 200 can be driven to stretch and retract efficiently.

In one embodiment, the cable mechanism 400 includes a cable guide 402, the cable guide 402 being coupled to the down-swinging beam 103 by a guide mounting bolt 404204. The cable 401 is in guiding fit with the cable guide 402, and the cable 401 is indirectly contacted with the lower swing beam 103 through the cable guide 402. The cable guide 402 prevents the cable 401 from being swung left and right, and the cable 401 stably performs a transmission function.

Specifically, the guide structure on the cable guide member 402 matched with the cable 401 may be a guide groove or a guide hole, so that the guide groove and the cable 401 are more convenient to assemble.

In one embodiment, the cable guide 402 is provided with a limiting portion 402a, and when the telescopic mechanism 200 extends to the limit position, the upper telescopic beam 202 abuts against the limiting portion 402a to limit the telescopic mechanism 200 to extend continuously. By the design, the inhaul cable guide piece 402 has a limiting function besides a guiding function, is multipurpose, and is more beneficial to simplifying the structure.

In one embodiment, the electric drive mechanism 300 includes a motor 301, a drive shaft 302, two recliners 303, a recliner bracket 304, and a motor bracket 306.

The fixed part of the recliner 303 is fixedly mounted to a recliner holder 304, the recliner holder 304 being adapted to be connected to the frame a of the car seat. Specifically, the recliner bracket 304 may be connected to the front side of the front cross member of the frame a of the vehicle seat (see fig. 5).

The motor 301 is fixedly mounted on a motor fixing frame 306, and the motor 301 is connected with the motor fixing frame 306 through a motor fixing bolt 307 and a gasket 308 in the figure. The motor mount 306 is adapted to be coupled to the frame a of the car seat. In the figure, the motor mount 306 is assembled to the adjuster mount, and since the recliner mount 304 is connected to the frame a of the car seat, the motor mount 306 is connected to the frame a of the car seat.

The motor 301 is in driving connection with a transmission shaft 302. The drive shaft 302 may be a spline shaft. The drive shaft 302 is in driving connection with the rotatable parts of the two recliners 303. The pivotable portions of the two recliners 303 are in driving connection with the two swing brackets 101, respectively. The motor 301 drives the transmission shaft 302 to rotate, thereby driving the rotatable portions of the two recliners 303 to rotate, thereby driving the two swing brackets 101 to rotate, and thus swinging the entire swing mechanism 100. The two angle adjusters 303 are used to drive the two swing brackets 101 to swing respectively, so that the swing motion of the swing mechanism 100 can be ensured to be stable.

In one embodiment, the electro-mechanical device 300 includes a stop bracket 305, the stop bracket 305 being coupled to the rotatable portion of the recliner 303. As shown in fig. 1, when the swing mechanism 100 swings backward to the limit position, the limit bracket 305 collides with the recliner bracket 304 to limit the swing mechanism 100 from further swinging backward.

In one embodiment, the telescopic bracket 201 is provided with a receiving groove 201a, one end of the telescopic bracket 201 facing the transmission shaft 302 is provided with an opening 201b communicated with the receiving groove 201a, and when the telescopic mechanism 200 is contracted to the limit position, the transmission shaft 302 enters the receiving groove 201a through the opening 201b, so that the telescopic stroke of the telescopic mechanism 200 is not influenced by the transmission shaft 302.

The above embodiments may be combined with each other without conflict.
