[0054] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0055] Example 1

[0056] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the first embodiment of the present invention provides a storage footrest device, which includes a frame assembly 200, a linkage bridge assembly 300, a connecting rod assembly 400, a support frame 500, a storage box 600 and a footrest assembly 700. The frame assembly 200 is fixed to the vehicle body frame, the support frame 500 is fixed to the frame assembly 200, the storage box 600 is fixed to the support frame 500, and the storage box 600 has a storage cavity 610 with an open end; the first end of the linkage bridge assembly 300 is slidably and rotatably connected to the frame assembly 200, the second end of the linkage bridge assembly 300 (i.e., the end away from the frame assembly 200) is rotatably connected to one end of the footrest assembly 700, and the other end of the footrest assembly 700 is suspended; one end of the connecting rod assembly 400 is hinged to the frame assembly 200, The other end is hinged to the linkage bridge assembly 300; the footrest assembly 700 can rotate between a first position and a second position relative to the linkage bridge assembly 300. When the first end of the linkage bridge assembly 300 slides on the frame assembly 200, the linkage bridge assembly 300 as a whole will move relative to the frame assembly 200, so that the second end of the linkage bridge assembly 300 will move away from or close to the storage box body 600. For the sake of convenience of description, the position where the second end of the linkage bridge assembly 300 is closest to the storage box body 600 is called the third position, and the position where the second end of the linkage bridge assembly 300 is farthest from the storage box body 600 is called the fourth position. Therefore, as the linkage bridge assembly 300 moves relative to the frame assembly 200, the second end of the linkage bridge assembly 300 will move between the third position and the fourth position.

[0057] like Figure 1 and Figure 2 As shown, when the second end of the linkage bridge assembly 300 is located at the third position and the footrest assembly 700 is located at the first position relative to the linkage bridge assembly 300, the footrest assembly 700 will cover the opening of the storage cavity 610. At this time, the storage cavity 610 is closed, the storage footrest device is in a closed state, and the passenger cannot use the storage cavity 610. Figure 4 and Figure 5 As shown, when the second end of the linkage bridge assembly 300 is located at the third position and the footrest assembly 700 is located at the second position relative to the linkage bridge assembly 300, the footrest assembly 700 will expose the opening of the storage cavity 610, thereby opening the storage cavity 610. At this time, the storage footrest device is in the open state, and the passenger can use the storage cavity 610, for example, to put items into the storage cavity 610 or take items out of the storage cavity 610. Figure 6 and Figure 7As shown, when the linkage bridge assembly 300 is in the fourth position, the second end of the linkage bridge assembly 300 is away from the storage box 600. At this time, the storage footrest device is in the footrest state, and the footrest assembly 700 can be used to support the occupant's legs, acting as a footrest. In the footrest state, the footrest assembly 700 can also rotate relative to the linkage bridge assembly 300, thereby adjusting the position of the footrest assembly 700 to adapt to the leg support needs of different occupants. Because the footrest assembly 700 can move with the linkage bridge assembly 300, the position adjustment range of the footrest assembly 700 is large, thereby achieving better support effects, for example, allowing the occupant to approach a zero-gravity state and improve comfort.

[0058] It can be understood that, since the footrest assembly 700 can move together with the second end of the linkage bridge assembly 300, during this process, the footrest assembly 700 will also move relative to the frame assembly 200 and the storage box body 600, so the position of the footrest assembly 700 relative to the frame assembly 200 and the storage box body 600 will change; and when the footrest assembly 700 rotates relative to the linkage bridge assembly 300, the position of the footrest assembly 700 relative to the frame assembly 200 and the storage box body 600 will also change; that is, the position of the footrest assembly 700 relative to the frame assembly 200 and the storage box body 600 is changed by the footrest assembly 700 relative to the frame assembly 200. It is jointly determined by the rotation of the linkage bridge assembly 300 and the movement of the linkage bridge assembly 300 relative to the frame assembly 200; to avoid ambiguity, the first position and the second position described in the embodiment of the present invention refer to the relative position between the footrest assembly 700 and the linkage bridge assembly 300, rather than the relative position between the footrest assembly 700 and the frame assembly 200 and the storage box 600. Therefore, when the linkage bridge assembly 300 is located at different positions, even if the footrest assembly 700 is located at the same position relative to the linkage bridge assembly 300, the actual position of the footrest assembly 700 (i.e., the position relative to the frame assembly 200) is also different.

[0059] like Figure 8 As shown, in some embodiments, the frame assembly 200 includes a frame 201 and a first driving mechanism, the first driving mechanism is arranged on the frame 201, the first end of the linkage bridge assembly 300 is slidingly connected to the frame 201, and the first driving mechanism is connected to the first end of the linkage bridge assembly 300, and is used to drive the first end of the linkage bridge assembly 300 to slide relative to the frame 201; the support frame 500 is fixed on the frame 201, one end of the connecting rod assembly 400 is hinged to the frame 201, and the first end of the linkage bridge assembly 300 is slidingly and rotatably connected to the frame 201.

The first motor 204 can be connected to one end of the screw rod 202 through the reducer 205, and the other end of the screw rod 202 can be installed on the frame 201 through the support 206, that is, the support 206 is fixed on the frame 201, and the end of the screw rod 202 is rotatably installed on the support 206.

[0061] Exemplarily, there are two ball screw mechanisms, one located on either side of the frame 201 in the Y direction, and the other two screw rods 202 extend in the Z direction. The first end of the linkage bridge assembly 300 in the X direction is hinged to the two drive nuts 203 on both sides in the Y direction. The first motor 204 is a dual-output coaxial motor having two output shafts, which are connected to one end of the two screw rods 202 via respective reducers 205, thereby driving the two screw rods 202 to rotate synchronously. The two output shafts can have the same rotational speed, and the two reducers 205 also have the same reduction ratio, thereby ensuring the same rotational speed for the two screw rods 202. X, Y, and Z are three orthogonal coordinate axes in a three-dimensional Cartesian coordinate system.

[0062] like Figure 9 As shown, in some embodiments, the footrest assembly 700 includes a footrest inner plate 701, a footrest frame 702 and a footrest outer plate 703. The footrest frame 702 is rotatably connected to the first end of the linkage bridge assembly 300 via a rotating shaft 704. The footrest inner plate 701 and the footrest outer plate 703 are fixedly connected, and an installation space is formed therebetween. The footrest frame 702 is fixed in the installation space, so that the footrest frame 702 is covered by the footrest inner plate 701 and the footrest outer plate 703, which serves an aesthetic purpose.

[0063] like Figure 10As shown, in some embodiments, the linkage bridge assembly 300 includes a linkage bridge body 301 and a second driving mechanism, the second driving mechanism is arranged on the linkage bridge body 301, the first end of the linkage bridge body 301 is slidingly and rotationally connected to the frame assembly 200, and the second end of the linkage bridge body 301 is rotationally connected to the footrest assembly 700, and the second driving mechanism is connected to the footrest assembly 700 to drive the footrest assembly 700 to rotate relative to the linkage bridge body 301.

[0064] The second driving mechanism may include a second motor 302 and a transmission element 303 . The second motor 302 is connected to the transmission element 303 , and the transmission element 303 is connected to the footrest assembly 700 . When the second motor 302 rotates, the footrest assembly 700 may be driven to rotate through the transmission element 303 .

[0065] The second end of the linkage bridge body 301 may be provided with at least one protrusion 304, and the foot support frame 702 may be provided with at least one avoidance groove 705 (such as Figure 9 As shown), the avoidance groove 705 corresponds to the protrusion 304 one by one, the protrusion 304 can be inserted into the avoidance groove 705, and then the rotating shaft 704 can pass through the footrest frame 702 and the protrusion 304, the rotating shaft 704 is fixedly connected to the footrest frame 702 (that is, there is no relative movement between the two), and is rotatably connected to the protrusion 304, that is, the rotating shaft 704 and the protrusion 304 can rotate relative to each other, thereby making the footrest frame 702 rotatably connected to the linkage bridge body 301.

[0066] The transmission element 303 may be a toothed plate, on which a plurality of first teeth 305 and a plurality of second teeth 306 are provided. The output shaft of the second motor 302 is provided with a plurality of third teeth 307, and the first teeth 305 and the third teeth 307 are meshed. Figure 11 As shown, a plurality of fourth teeth 706 may be provided on the footrest frame 702 or the rotating shaft 704, and the fourth teeth 706 are engaged with the second teeth 306, and the transmission element 303 is rotatably connected with the linkage bridge body 301. In this way, when the second motor 302 rotates, the transmission element 303 will be rotated through the engagement between the third teeth 307 and the first teeth 305, and the rotation of the transmission element 303 will cause the footrest frame 702 to rotate through the engagement between the second teeth 306 and the fourth teeth 706.

[0067] The linkage bridge assembly 300 may further include a cover plate 308 , which is fixed on the linkage bridge body 301 and covers the second driving mechanism to achieve an aesthetic effect.

[0068] like Figure 3As shown, the connecting rod assembly 400 may include at least one connecting rod 401, one end of the connecting rod 401 is hinged to the frame assembly 200, and the other end of the connecting rod 401 is hinged to the linkage bridge body 301, so that when the linkage bridge body 301 moves relative to the frame assembly 200, the connecting rod 401 will also rotate relative to the linkage bridge body 301 and the frame assembly 200. Exemplarily, there are two connecting rods 401, and they are arranged opposite to each other along the Y direction. The two connecting rods 401 are respectively located on both sides of the linkage bridge body 301 in the Y direction, and one end of the two connecting rods 401 is respectively hinged to both sides of the linkage bridge body 301 in the Y direction, and the other ends of the two connecting rods 401 can be respectively hinged to the two supports 206. Each connecting rod 401 can be connected to the linkage bridge body 301 through an axle pin 309 (such as Figure 10 401) is hingedly connected to the linkage bridge body 301. An axle pin 309 may be fixed to the linkage bridge body 301 and pass through one end of the connecting rod 401. The axle pin 309 is rotatably connected to the connecting rod 401, thereby hingedly connecting the connecting rod 401 to the linkage bridge body 301. The axle pin 309 may be fixed between the first and second ends of the linkage bridge body 301 (e.g., in the middle), so that the hinge point between the linkage bridge body 301 and the connecting rod 401 is located between the first and second ends of the linkage bridge body 301.

[0069] It is understandable that, although in the above embodiment, the frame assembly 200 and the support frame 500 are two components, in other embodiments, the frame assembly 200 and the support frame 500 may also be formed as one component to serve as a base.

[0070] The principle of switching between the closed and open states of the storage footrest device is as follows:

[0071] like Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, when the second motor 302 drives the third gear 307 to rotate counterclockwise, the tooth plate 303 will rotate clockwise. The clockwise rotation of the tooth plate 303 causes the footrest frame 702 to rotate counterclockwise, so that the footrest frame 702 will rotate toward the second position, causing the storage footrest device to switch to the open state. Conversely, when the second motor 302 drives the third gear 307 to rotate clockwise, the footrest frame 702 will rotate toward the first position, causing the storage footrest device to switch to the closed state. The linkage bridge body 301 is provided with a first limiting structure 3041. For example, the first limiting structure 3041 can be provided on the protrusion 304. The first limiting structure 3041 is used to abut the footrest frame 702 when the footrest frame 702 rotates to the second position, thereby limiting the footrest frame 702 from further rotation, thereby limiting the second position of the footrest frame 702.

[0072] The switching principle of the storage footrest device between the closed state and the footrest state is as follows:

[0073] As shown in Figure 16A and Figure 17A , when the storage footrest device is in the closed state, the first end of the linkage bridge assembly 300 and the transmission nut 203 are located at the lower position of the frame 201, and when the storage footrest device is in the footrest state, the first end of the linkage bridge assembly 300 and the transmission nut 203 are located at the higher position of the frame 201; when the first motor 204 drives the transmission nut 203 to move upward, the second end of the linkage bridge assembly 300 and the footrest assembly 700 will move away from the storage box 600 and towards the fourth position, and the storage footrest device will switch to the footrest state; conversely, when the first motor 204 drives the transmission nut 203 to move downward, the second end of the linkage bridge assembly 300 and the footrest assembly 700 will move towards the storage box 600 and towards the third position, and the storage footrest device will switch to the closed state. As shown in Figure 16B and Figure 17B , the linkage bridge assembly 300 is provided with a first stop structure 300a and a second stop structure 300b; when the second end of the linkage bridge assembly 300 moves to the third position, the first stop structure 300a abuts against the connecting rod 401 and interferes with each other, thereby limiting the third position of the linkage bridge assembly 300; when the second end of the linkage bridge assembly 300 moves to the fourth position, the second stop structure 300b abuts against the linkage bridge assembly 300 and interferes with each other, thereby limiting the fourth position of the linkage bridge assembly 300.

[0074] As shown in Figure 18A , the storage footrest device can be arranged at the co-pilot position of the vehicle, which can cooperate with the vehicle seat to realize the storage function and the footrest function. As shown in Figure 18B , when the vehicle seat is in the designed posture, the storage footrest device can be used as a glove box to realize the storage function. As shown in Figure 18C , when the vehicle seat is in the zero-pressure posture, the footrest assembly 700 of the storage footrest device can support the legs of the occupant, thereby being used as a footrest.

[0077] As Figure 20 and Figure 21 As shown, the frame assembly 220 of the second embodiment includes a frame 221 and at least one guide mechanism, which includes a guide post 222 and a guide sleeve 223. The guide post 222 is fixed to the frame 221, and the guide sleeve 223 is sleeved on the guide post 222 and can slide along the guide post 222. The first end of the linkage bridge assembly 320 is hingedly connected to the guide sleeve 223, thereby enabling the first end of the linkage bridge assembly 320 to be slidably and rotatably connected to the frame assembly 220. For example, there may be two guide mechanisms, one located on either side of the frame 221 in the Y direction. Both guide posts 222 extend in the Z direction, allowing the guide sleeve 223 to slide in the Z direction. The first end of the linkage bridge assembly 320 is hingedly connected to the two guide sleeves 223 on either side in the Y direction. The guide post 222 can be fixed to the frame 221 via two supports 224. Specifically, the two supports 224 are fixed to the frame 221, and the two ends of the guide post 222 are respectively fixed to the two supports 224.

[0078] like Figure 22 and Figure 23 As shown, the linkage bridge assembly includes a linkage bridge body 321, a second drive mechanism, and a third drive mechanism. The second drive mechanism includes a second motor 322 and a transmission element 323. The structure of the second motor 322 and transmission element 323, as well as their connection to the footrest assembly 700, are the same as those in the first embodiment and will not be further described here. The linkage bridge assembly 320 also includes a cover plate 324 fixedly connected to the linkage bridge body 321 to cover the second drive mechanism. The third drive mechanism includes a third motor 325 and at least one drive pin 326. The third motor 325 is connected to the drive pin 326. The drive pin 326 is rotatably connected to the linkage bridge body 321 and fixedly connected to one end of the connecting rod assembly 400. In this way, the connecting rod assembly 400 is hingedly connected to the linkage bridge body 321. When the third motor 325 rotates, the drive pin 326 rotates with it, and the connecting rod assembly 400 also rotates relative to the linkage bridge body 321, thereby driving the linkage bridge body 321. Exemplarily, there are two transmission shaft pins 326, and the connecting rod assembly 400 includes two connecting rods 401, and the two connecting rods 401 correspond one-to-one to the two transmission shaft pins 326 and one-to-one to the two guide columns 222. One end of the connecting rod 401 is fixed to the corresponding transmission shaft pin 326, and the other end of the connecting rod 401 is hinged to one of the supports 224 of the corresponding guide column 222 (for example, the lower support 224); the third motor 325 is a dual-output coaxial motor, and its two output shafts are respectively connected to the two transmission shaft pins 326.

[0079] The principle of switching between the closed state and the footrest state of the storage footrest device of the second embodiment is as follows:

[0080] like Figure 24 and Figure 25As shown, when the storage footrest device is in the closed state, the first end of the linkage bridge assembly 300 and the guide sleeve 223 are at the lower position of the guide column 222; when the storage footrest device is in the footrest state, the first end of the linkage bridge assembly 300 and the guide sleeve 223 are at the higher position of the guide column 222; when the third motor 325 drives the transmission shaft pin 326 to rotate counterclockwise, the first end of the linkage bridge assembly 300 and the guide sleeve 223 will slide upward along the guide column 222, and the second end of the linkage bridge assembly 300 will move toward the fourth position, thereby switching the storage footrest device to the footrest state; conversely, when the third motor 325 drives the transmission shaft pin 326 to rotate clockwise, the first end of the linkage bridge assembly 300 and the guide sleeve 223 will slide downward along the guide column 222, and the second end of the linkage bridge assembly 300 will move toward the third position, thereby switching the storage footrest device to the closed state. The connecting rod 401 may be configured to interfere with the linkage bridge assembly 300 when the second end of the linkage bridge assembly 300 moves to the third position and the fourth position, thereby defining the third position and the fourth position of the linkage assembly 300 .

[0081] Example 3

[0082] like Figure 26 As shown, the third embodiment of the present invention provides a storage footrest device. Based on the first embodiment, a slide groove 207 is added to the frame 201, and a guide pin 208 is added to the drive nut 203. The guide pin 208 is inserted into the slide groove 207 and can slide along the slide groove 207. When the drive nut 203 slides along the screw rod 202, the guide pin 208 can be simultaneously in the slide groove 207, which can support the drive nut 203 and prevent the drive nut 203 from shaking and making abnormal noises during the sliding process along the screw rod 202. For example, the frame 201 can be provided with two extension frames extending along the Z direction, and the two extension frames are respectively located on both sides of the Y direction. Each extension frame is provided with a slide groove 207, which respectively cooperates with the guide pins 208 on the two drive nuts 203.

[0083] The storage footrest device of the embodiment of the utility model can open or close the storage box 600 by rotating the footrest assembly 700 relative to the linkage bridge assembly 300 to realize the storage function; the second end of the linkage bridge assembly 300 can be moved away from or close to the storage box 600 by moving the linkage bridge assembly 300 relative to the frame assembly 200 to realize the footrest function; by integrating the storage function and the footrest function in one device, the space occupancy can be reduced, so that the storage and footrest functions can be simultaneously realized in the limited space in the vehicle.
