[0002] With the advancement of science and technology and the development of the automotive industry, people's demands for the quality and comfort of car seats are constantly increasing. In order to relieve leg pressure while riding in a car, existing car seats are equipped with leg rest structures for massaging passengers' legs.

[0003] In existing car leg rest structures, the massage device only massages the back of the calf in one situation, making it difficult to achieve a massage effect when the passenger's legs are tilted or the position is off.

[0004] Given the above, many leg rests have protruding parts designed to restrain the legs; however, this design can cause discomfort when the legs are restrained for extended periods. Therefore, how to ensure the massage effect while avoiding prolonged leg restraint has become a current technical challenge. Utility Model Content

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0062] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0063] Please refer to Figure 1-2 and Figure 7 This utility model provides a seat-adjustable leg rest lifting and massage device, comprising:

[0064] Leg support frame 10 and bearing layer 1, wherein the bearing layer 1 is disposed on the leg support frame 10;

[0065] A first massage component is mounted on the support layer 1 and is used to massage the leg 2 along a first direction;

[0066] A drive assembly is mounted on the leg support frame 10; a mounting block 7 is mounted on the drive assembly; the mounting block 7 has a first state and a second state.

[0067] When the mounting block 7 is in the first state, the mounting block 7 is housed in the bearing layer 1;

[0068] When the mounting block 7 is in the second state, the mounting block 7 extends out of the surface of the bearing layer 1 near the leg 2 in the first direction;

[0069] A second massage component is mounted on the mounting block 7 and is used to massage the leg 2 along a second direction when the mounting block 7 is in the second state; the first direction and the second direction are perpendicular to each other.

[0070] The driving component is used to drive the mounting block 7 to switch between the first state and the second state.

[0071] Specifically, the first direction is the front-back direction of leg 2; the second direction is the left-right direction of leg 2.

[0072] The drive component is used to move the mounting block 7 and the second massage component along the first direction, so the second massage component has a first state and a second state.

[0073] When the mounting block 7 is in the second state, the second massage component protrudes from the leg rest and foams, and the second massage component can massage the legs in the second direction.

[0074] Therefore, for reference Figure 3-4 and Figure 8-9 The first and second massage components can massage the legs in two directions respectively, ensuring the massage effect.

[0075] When massage is not needed, the controllable drive component can move the mounting block 7 to house the second massage component in the support layer 1, allowing the legs 2 to move freely and avoiding prolonged restriction of leg movement, which could cause discomfort to the passenger.

[0076] Furthermore, the first massage component is a pneumatic or mechanical structure.

[0077] Furthermore, the second massage component is a pneumatic or mechanical structure.

[0078] Specifically, refer to Figure 17-18 The pneumatic structure includes a first air bag 6, which achieves a massage effect by repeatedly inflating and deflating air during use.

[0079] Furthermore, the mechanical structure includes:

[0080] Drive component 9, which is installed within the mounting block 7;

[0081] Transmission component 8, which is movably installed within the mounting block 7;

[0082] Massage protrusion 5, which is fixedly connected to the transmission component 8 and is located near the leg 2;

[0083] The driving component 9 is used to drive the transmission component 8 to move relative to the mounting block 7, and to drive the massage protrusion 5 to protrude out of the mounting block 7 or retract into the mounting block 7.

[0084] In some embodiments, the drive element 9 is an air bag, a telescopic frame, or a turntable with wedge-shaped protrusions.

[0085] When the driving component 9 is an air bag, the inflation and deflation of the air drive the transmission component 8 and the massage protrusion 5 to move.

[0086] When the drive component 9 is a telescopic frame, the telescopic frame is reciprocated and extended by the motor, which drives the massage protrusions 5 to move.

[0087] When the driving component 9 is a turntable with wedge-shaped protrusions, the rotation axis of the turntable is parallel to the direction of movement of the massage protrusions 5. As the wedge-shaped protrusions rotate with the turntable, they indirectly abut against the transmission component 8, thereby driving the massage protrusions 5 to move.

[0088] The massage protrusion 5 moves relative to the mounting block 7 to achieve a massage effect.

[0089] Specifically, refer to Figure 5-6 It also includes an interconnected air circuit controller 3 and an air pump 4.

[0090] Specifically, the air pump 4 continuously supplies gas, and the air circuit controller 3 transmits the gas supplied by the air pump 4 to the first air bag 6 of the first massage component and the drive component 9 (in this embodiment, the drive component 9 is an air bag) of the second massage component. The air circuit controller 3 repeatedly inflates and deflates the first and second massage components, causing the first air bag 6 and the drive component 9 to repeatedly expand / contract, thereby driving the massage protrusions 5 to repeatedly clamp / release the leg 2 to achieve a massage effect.

[0091] Further, refer to Figure 10-12 The driving component includes:

[0092] Drive mechanism 11, which is mounted on the leg support frame 10;

[0093] Telescopic bracket 12, which is mounted on the leg support frame 10 and one end is connected to the drive mechanism 11;

[0094] Connecting block 13, which is connected to the other end of telescopic bracket 12; mounting block 7 is fixedly connected to connecting block 13;

[0095] The telescopic bracket 12 is used to drive the connecting block 13, the mounting block 7 and the second massage component to move along the first direction under the action of the drive mechanism 11.

[0096] Specifically, the mounting block 7 is fitted onto the outside of the connecting block 13 and is fixedly connected to it.

[0097] The drive mechanism causes the telescopic bracket 12 to extend, causing the connecting block 13, mounting block 7, massage protrusion 5, and drive component 9 to protrude from the surface of the leg support foam 1. Since the massage protrusion 5 faces the second direction, it can massage the leg 2 along the second direction.

[0098] When massage is not needed, the drive mechanism causes the telescopic bracket 12 to retract, causing the second massage component to retract back into the leg support foam 1, so that the upper surface of the mounting block 7 is flush with the leg support foam 1.

[0099] Further, refer to Figure 13-16 The leg support frame 10 is also equipped with a limiting groove 14;

[0100] The connecting block 13 is threaded or integrally formed with a limiting protrusion 15; the limiting protrusion 15 has a protrusion 16 at one end near the limiting groove 14; the protrusion 16 is used to be engaged in the limiting groove 14 to fix the relative position between the connecting block 13 and the leg support frame 10.

[0101] Specifically, in some cases, the connecting block 13 may move to an excessively high position and detach from the leg support frame 10; therefore, a limiting groove 14 is provided to limit the connecting block 13 and prevent the connecting block 13 from detaching from the leg support frame 10.

[0102] Furthermore, the limiting protrusion 15 is threaded with a reinforcing rib 17, which is used to support the limiting protrusion 15.

[0103] In some implementations, to reduce overall weight, the limiting protrusion 15 is not made of metal, but of plastic. Therefore, when the limiting protrusion 15 generates excessive force with the limiting groove 14 under the action of the connecting block 13, the limiting protrusion 15 may bend or break.

[0104] Therefore, without significantly increasing the overall weight, reinforcing ribs 17 are provided to enhance the structural strength of the limiting protrusions 15.

[0105] Furthermore, the drive mechanism 11 includes:

[0106] Lead screw 18, which is rotatably mounted on the leg support frame 10;

[0107] A lead screw nut 19 is threaded onto the lead screw 18 and connected to one end of the telescopic bracket 12.

[0108] The drive device 20 has its rotating shaft fixedly connected to the lead screw 18, which is used to drive the lead screw 18 to rotate and drive the telescopic bracket 12 to extend and retract in the first direction through the lead screw nut 19.

[0109] Furthermore, the telescopic bracket 12 includes:

[0110] Sliding block 21, which is slidably mounted on the leg support frame 10 and connected to the drive mechanism 11;

[0111] Two first support rods 22 are hinged to each other, and the two ends of the two first support rods 22 that are far apart from each other are respectively hinged to the leg support frame 10 and the connecting block 13;

[0112] Two hinged second support rods 23, with their ends far apart from each other, one end of which is hinged to the sliding block 21 and the other end is slidably connected to the connecting block 13;

[0113] The first support rod 22 and the second support rod 23 are hinged to each other.

[0114] Specifically, the sliding block 21 is fixedly connected to the lead screw nut 19.

[0115] The control drive device 20 drives the lead screw 18 to rotate. Since the sliding block 21 is fixedly connected to the lead screw nut 19, the sliding block 21 and the lead screw nut 19 slide relative to the leg support frame 10 at the same time, which drives the first support rod 22 and the second support rod 23 to rotate relative to each other. The change in the included angle between the two realizes the telescopic bracket 12 to perform telescopic action.

[0116] Furthermore, the drive assembly, mounting block 7, and second massage assembly are all provided in multiple sets, respectively located on both sides of the two legs 2; the multiple sets of the second massage assembly are used to massage along both sides of the two legs 2.

[0117] Specifically, in order to massage both legs 2, this embodiment provides three sets of the drive components and the second massage components. The three sets of the second massage components are arranged along the second direction, and the two legs 2 are respectively positioned between two adjacent second massage components for massage.

[0118] Furthermore, the connecting block 13 in the second massage assembly located between the two legs 2 has an arc-shaped end near the occupant's body.

[0119] Specifically, when the leg 2 is positioned between the two sets of second massage components, the connecting block 13 with an arc-shaped end can prevent sharp parts from contacting the leg 2 and causing discomfort to the passenger.

[0120] The above description is merely a preferred embodiment of this utility model and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this utility model is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
