Description

Technical Field

[0001] The present application relates to the field of vehicle technology. Background Art

[0002] People have a growing demand for vehicle space. Existing three-row vehicles generally increase the wheelbase to meet users' space needs along the length of the vehicle. However, the rear seats are set on the rear floor assembly. Due to the limitations of the seats in the cabin, when the rear seats are not in use, the space above the rear floor assembly cannot be effectively utilized, making it difficult to meet users' space needs in the height direction of the vehicle.

[0003] At present, some vehicles use folding seats for the rear seats. By folding the seats and flipping them for storage, the user's space requirement in the height direction of the vehicle can be increased. However, the existing folding seats are all flipped manually, which makes it difficult to flip them for vehicles with multiple seats in the rear. In addition, for new energy vehicles, the structural layout between the rotation axis of the existing folding seats and the drive motor is unreasonable, resulting in a certain amount of space waste in the height and length directions inside the vehicle.

DETAILED DESCRIPTION

[0034] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0035] In the following description of this application, the terms "front" and "rear" are based on the azimuth relationship that the forward direction of the vehicle is the front and the backward direction of the vehicle is the rear. Figure 1 The Y direction is the front-to-back direction, the X direction is the left-to-right direction, and the Z direction is the up-down direction.

[0036] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] like Figure 1-3 As shown, a vehicle of a preferred embodiment of the present application comprises a rear floor assembly 2, a flip motor 4 and a folding seat 1 arranged in the cabin of the vehicle, wherein the rear floor assembly 2 comprises a conversion portion 21 and a storage portion 22, wherein the conversion portion 21 is arched upwards and is provided with a use position 211 of the folding seat 1, wherein the bottom of the conversion portion 21 has a receiving space 212, wherein a rear drive motor 31 is provided in the receiving space 212, wherein the rear drive motor 31 is used to provide power for the vehicle. The storage portion 22 is provided with a storage cavity 221 for storing the folding seat 1; the flip motor 4 is used to drive the folding seat 1 to flip around the rotating shaft 41 of the flip motor 4 to the use position 211 for use, or to be stored in the storage cavity 221. Among them, the axis of the rotating shaft 41 of the flip motor 4 is parallel to the axis of the rotating shaft 311 of the rear drive motor 31, and the distance between the two in the height direction is Z1, 220mm≤Z1≤320mm, such as 220mm, 230mm, 240mm, 250mm, 260mm, 270mm, 280mm, 290mm, 300mm, 310mm, etc.; Z1 can also be any value or any range between any two of the above values, such as Z1 is 300±20mm; or Z is: 220mm≤Z1≤300mm; or Z1 is: 300mm≤Z1≤320mm.

[0038] The distance between the axis of the rotating shaft 41 of the flip motor 4 and the axis of the rotating shaft 311 of the rear drive motor 31 in the vehicle length direction is Y1, 280mm≤Y1≤380mm, such as 290mm, 300mm, 310mm, 320mm, 330mm, 340mm, 350mm, 360mm, 370mm, etc.; Z can also be any value or any range between any two values ​​of the above values, such as Y1 is 350±30mm; or Y1 is: 280mm≤Y1≤350mm; or Y1 is: 350mm≤Y1≤380mm.

[0039] Based on the above-mentioned numerical range of Y1 and Z1, under the premise of ensuring that the flip motor 4 and the rear drive motor 31 do not interfere with each other, the flip motor 4 and the rear drive motor 31 can have the most compact design and occupy the smallest space, thereby ensuring that the space in the length and height directions of the vehicle is increased without changing the vehicle size (length, width, height) and wheelbase.

[0040] Specifically, if the distance between the axis of the rotating shaft 41 of the flip motor 4 and the axis of the rotating shaft 31 of the rear drive motor 31 is greater than the setting value of the present application, it will cause space waste between the folding seat 1 and the rear drive motor 31 after the folding seat 1 is folded; if the distance between the axis of the rotating shaft 41 of the flip motor 4 and the axis of the rotating shaft 311 of the rear drive motor 31 is less than the setting value of the present application, it will cause interference between the folding seat 1 and the rear drive motor 31 and the vehicle body after the folding seat 1 is folded. The distance between the axis of the rotating shaft 41 of the flip motor 4 and the axis of the rotating shaft 311 of the rear drive motor 31 in the height direction is between 220mm and 320, and the distance in the vehicle length direction is between 280mm and 380mm, which matches the size of the folded folding seat 1, ensuring that after the seat is folded, there is no waste of space between the rear drive motor 31, and no interference with the rear drive motor 31 and the vehicle body, thereby achieving the optimal dynamic space required for the flipping and sinking of the folding seat 1, and ensuring that the space in the length and height directions of the vehicle is increased without changing the vehicle size and wheelbase.

[0041] In addition, by providing a flip motor 4 to drive the folding seat 1 to flip around the rotating shaft 41 of the flip motor 4 to the use position 211 or the storage cavity 221, the flipping, storage or use of the folding seat 1 is facilitated.

[0042] In this embodiment, when the foldable seat 1 is needed to be used, it is flipped to the use position 211; when the space in the vehicle needs to be expanded, the foldable seat 1 is stored in the storage cavity 221, so that the space above the conversion portion 21 is the space in the vehicle. In order to ensure that the space in the vehicle is as large as possible after the foldable seat 1 is flipped to the storage cavity 221 and is convenient to use, the storage portion 22 is recessed downward, so that after the foldable seat 1 is flipped to the storage cavity 221, the top of the foldable seat 1 is substantially flush with the use position 211. When the foldable seat 1 is stored in the storage cavity 22, the upper end surface of the foldable seat 1 and the upper end surface of the use position 211 are relatively flat, which is convenient for users to use.

[0043] In this embodiment, the folding seat 1 includes a seat cushion 11 and a backrest 12 which can be folded into one, and the rotating shaft of the flip motor 4 is assembled on the seat cushion 11; when the folding seat 1 is flipped around the rotating shaft of the flip motor 4 to the use position, the backrest 12 is located above the seat cushion 11, and the seat cushion 11 is supported above the conversion part 21; when the folding seat 1 is flipped to the storage cavity 22, the folding seat 1 is located behind the conversion part, and the seat cushion 11 is located above the backrest 12.

[0044] The rear of the conversion portion 21 may refer to the direction of the conversion portion 21 toward the rear of the vehicle, or may refer to the trunk of the vehicle. Before the foldable seat 1 is turned over to the storage cavity 22, the foldable seat 1 may be in a folded state in advance, so as to facilitate the foldable seat 1 to be turned over to the storage cavity 22. Figure 2 The foldable seat 1 in the dotted line portion is in the storage cavity 22 , and the foldable seat 1 in the solid line portion is in the use position.

[0045] In some embodiments, the rotating shaft of the flip motor 4 can be inserted through the seat cushion 11 or outside the seat cushion 11. The specific setting is determined according to the values ​​of Y1 and Z1 mentioned above. It should be noted that for the present application, the folding seat 1 is the rear seat of the vehicle, and the rear seat does not have a movable function in the longitudinal direction of the vehicle. Therefore, after the setting, the relative position of the flip motor 4 and the rear drive motor 31 is determined.

[0046] In addition, the vehicle may also be provided with a locking handle, which may be assembled to the rear floor assembly 2 through an anchor bracket, and when the locking handle is in a locked state, the seat cushion 11 of the folding seat 1 and the rear floor assembly 2 may be locked, so that the seat cushion 11 of the folding seat 1 cannot be flipped relative to the rear floor assembly 2. When the locking handle is in an unlocked state, the seat cushion 11 of the folding seat 1 and the rear floor assembly 2 may be loosened, so that the seat cushion 11 of the folding seat 1 may be moved around the flip axis of the folding seat 1 to the use position and the storage cavity 22, which helps the user to adjust the position of the folding seat.

[0047] In some embodiments, the vehicle may be a bridge car, SUV, MPV or other vehicle. The vehicle may be a three-row seat vehicle. A three-row seat vehicle may be understood as a vehicle having six or seven seats, or may be understood as a vehicle having a front row seat, a middle seat and a rear row seat.

[0048] In some embodiments, the number of the front seats may be two, and both front seats may be independent seats.

[0049] In some embodiments, the number of the middle seats can be one to two. When the number of the middle seat is one, the middle seat can be an integrated two-seat seat or an integrated three-seat seat. When the number of the middle seats is two, both middle seats can be independent seats.

[0050] In some embodiments, the number of rear seats can be one to three. When the number of rear seats is one, the rear seat can be an integrated two-seat seat or an integrated three-seat seat. When the number of rear seats is two, both rear seats can be independent seats, or one rear seat is an independent seat and the other rear seat is an integrated two-seat seat. When the number of rear seats is three, all three rear seats can be independent seats.

[0051] In this embodiment, the vehicle further includes a carpet 5, which is laid on the rear floor assembly 2. When the foldable seat 1 is flipped over to the storage cavity 22, the height difference between the backrest 12 and the carpet 5 located in the use position is d, and d is less than or equal to 10 mm, such as 9 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3 mm, 2 mm, 1 mm, 0 or any value or range between any two of the above values. In this way, when the foldable seat 1 is stored in the storage cavity 22, the upper end surface of the foldable seat 1 and the part of the conversion portion 21 where the carpet 5 is located are relatively flat, which is convenient for users to use.

[0052] That is, when the foldable seat 1 is flipped over to the storage cavity 22 , the backrest 12 may be higher than the carpet 5 located at the conversion portion 21 , the backrest 12 may be lower than the carpet 5 located at the conversion portion 21 , or the backrest 12 may be flush with the carpet 5 located at the conversion portion 21 .

[0053] Please refer to the attached Figure 6 In this embodiment, the vehicle further includes a rear suspension 6, the rear suspension 6 is mounted on the rear floor assembly 2, and the rear drive motor 31 is mounted on the rear suspension 6. Specifically, the rear suspension 6 includes a front crossbeam 61 and a rear crossbeam 62 that are arranged opposite to each other, and the rear drive motor 31 is arranged between the front crossbeam 61 and the rear crossbeam 62. At the same time, the vehicle further includes a rear wheel steering gear 7 arranged in the accommodating space, the rear wheel steering gear 7 is mounted on the rear suspension 6, and the rear wheel steering gear 7 is located on the side of the rear drive motor 31 facing the front of the vehicle. The rear suspension 6, the rear wheel steering gear 7 and the rear drive motor 31 are integrated into a whole, and then fixed on the rear floor assembly 2 to form the entire rear axle system structure assembly.

[0054] Since the rear axle of the vehicle is integrated as a whole, it is helpful to improve the integration of the rear axle of the vehicle and improve the internal space of the vehicle. At the same time, the rear wheel steering device 7 is provided so that the rear wheel 100 of the vehicle can also deflect at a certain angle during driving, which can compensate for the defects of the vehicle steering mechanism caused by the tire, thereby reducing the turning radius of the vehicle and improving the operating performance of the vehicle.

[0055] Please refer to the attached Figure 4 , 5 In this embodiment, the rear drive motor 31 is connected to a rear reducer 32, the rear drive motor 31 and the rear reducer 32 are arranged along the left-right direction of the vehicle, and the rotating shaft of the rear drive motor 31 is coaxially arranged with the output shaft of the rear reducer 32. Preferably, the rear drive motor 31 and the rear reducer 32 form a rear electric drive assembly 3, the dimension of the rear electric drive assembly 3 along the front-to-back direction of the vehicle is Y2, and the dimension of the rear electric drive assembly 3 along the height direction of the vehicle is Z2, 300mm≤Y2≤400mm, 250mm≤Z2≤310mm. This helps to make the structure of the rear electric drive assembly 3 more compact, and also helps to reduce the space occupied by the rear electric drive assembly 3 along the front-to-back direction and the height direction of the vehicle, thereby helping to provide a larger space in the vehicle's cabin.

[0056] For example, when the rear drive motors have the same power and torque, the rear drive motor 31 and the rear reducer 32 are coaxially arranged, then the size of the rear electric drive assembly 3 along the front-to-back direction of the vehicle is approximately 390 mm, and the size of the rear electric drive assembly 3 along the height direction of the vehicle is approximately 310 mm; while other schemes, such as the rear drive motor and the rear reducer are arranged in parallel axes, the size of the rear electric drive assembly arranged in parallel axes along the front-to-back direction of the vehicle is approximately 470 mm, and the size along the height direction of the vehicle is approximately 480 mm; then the rear electric drive assembly 3 of the embodiment of the present application, when coaxially arranged, is approximately 80 mm smaller in the front-to-back direction of the vehicle than in the case of parallel axis arrangement, and is approximately 70 mm smaller in the height direction of the vehicle than in the case of parallel axis arrangement, thereby reducing the spatial position occupied by the rear electric drive assembly along the front-to-back direction and height direction of the vehicle.

[0057] In some embodiments, the dimension Y2 of the rear electric drive assembly 3 along the front-to-rear direction of the vehicle can be 300mm, 310mm, 320mm, 330mm, 340mm, 350mm, 360mm, 370mm, 380mm, 390mm, 400mm or any value or any range between any two adjacent values ​​mentioned above.

[0058] For example, the dimension of the rear electric drive assembly 4 along the front-rear direction of the vehicle may be 390 mm±10 mm.

[0059] For another example, the dimension of the rear electric drive assembly 4 along the front-rear direction of the vehicle may be: 390 mm ≤ Y2 ≤ 400 mm, or 390 mm ≤ Y2 ≤ 400 mm.

[0060] For another example, the size of the rear electric drive assembly 4 along the front-to-rear direction of the vehicle may be: 300mm≤Y2≤390mm; 300mm≤Y2≤380mm; 300mm≤Y2≤370mm; 300mm≤Y2≤360mm; 300mm≤Y2≤350mm; 300mm≤Y2≤340mm; 300mm≤Y2≤330mm; 300mm≤Y1≤320mm; or 300mm≤Y1≤310mm.

[0061] In this way, the size of the rear electric drive assembly 3 along the front-to-rear direction Y2 of the vehicle is within the above-mentioned values ​​and ranges, which helps to avoid the size of the rear electric drive assembly 3 along the front-to-rear direction of the vehicle being too large and occupying too much space in the front-to-rear direction, and also helps to avoid the size of the rear electric drive assembly 3 along the front-to-rear direction of the vehicle being too small, resulting in the power and torque of the rear electric drive assembly 3 being limited by its small size and unable to be configured larger.

[0062] In some embodiments, the dimension of the rear electric drive assembly 3 along the height direction Z2 of the vehicle can be 250mm, 255mm, 260mm, 265mm, 270mm, 275mm, 280mm, 285mm, 290mm, 295mm, 300mm, 305mm, 310mm or any value or any range between any two adjacent values ​​mentioned above.

[0063] For example, the dimension of the rear electric drive assembly 3 along the height direction of the vehicle may be 310 mm±10 mm.

[0064] For another example, the dimension of the rear electric drive assembly 3 along the height direction of the vehicle may be greater than or equal to 250 mm and less than 310 mm.

[0065] For another example, the dimension of the rear electric drive assembly 3 along the height direction of the vehicle may be greater than or equal to 250 mm and less than or equal to 305 mm, or greater than or equal to 250 mm and less than or equal to 300 mm, or greater than or equal to 250 mm and less than or equal to 295 mm, or greater than or equal to 250 mm and less than or equal to 290 mm, or greater than or equal to 250 mm and less than or equal to 285 mm, or greater than or equal to 250 mm and less than or equal to 280 mm, or greater than or equal to 250 mm and less than or equal to 275 mm, or greater than or equal to 250 mm and less than or equal to 270 mm, or greater than or equal to 250 mm and less than or equal to 265 mm, or greater than or equal to 250 mm and less than or equal to 260 mm, or greater than or equal to 250 mm and less than or equal to 255 mm.

[0066] In this way, the dimension Z2 of the rear electric drive assembly 3 along the height direction of the vehicle within the above-mentioned values ​​and ranges can help avoid the dimension of the rear electric drive assembly 3 along the height direction of the vehicle being too large and occupying too much space in the height direction, and can also help avoid the dimension of the rear electric drive assembly along the height direction of the vehicle being too small, resulting in the power and torque of the rear electric drive assembly 3 being limited by its small size and unable to be configured larger.

[0067] In some embodiments, the rated power of the rear drive motor 41 is P, and P may be greater than or equal to 50 kW and less than or equal to 150 kW. For example, P may be 50 kW, 55 kW, 60 kW, 65 kW, 70 kW, 75 kW, 80 kW, 85 kW, 90 kW, 95 kW, 100 kW, 105 kW, 110 kW, 115 kW, 120 kW, 125 kW, 130 kW, 135 kW, 140 kW, 145 kW, 150 kW, or any value or any range between any two adjacent values ​​mentioned above.

[0068] For example, P may be 135 kW ± 5 kW.

[0069] For another example, P may be: 135kW≤P≤150kW, or 50kW≤P≤135kW.

[0070] For another example, P may also be: 145kW≤P≤150kW; 140kW≤P≤150kW, 50kW≤P≤135kW, 50kW≤P≤130kW, 50kW≤P≤120kW, 50kW≤P≤110kW, 50kW≤P≤100kW, 50kW≤P≤90kW, 50kW≤P≤80kW, 50kW≤P≤70kW, or 50kW≤P≤60kW.

[0071] In this way, the rated power of the rear-drive motor 31 is within the above-mentioned numerical value and range, which helps to avoid the rated power of the rear-drive motor 31 being too large, resulting in the size of the rear-drive motor 31 being too large and occupying too much space in the front-to-back direction and height direction of the vehicle, and also helps to avoid the rated power of the rear-drive motor 31 being too small, resulting in the load-bearing capacity of the rear electric drive assembly 3 being too small.

[0072] In some embodiments, the rated torque of the rear drive motor 31 is T, and T may be greater than or equal to 130 N·m and less than or equal to 210 N·m. For example, T may be 130 N·m, 135 N·m, 140 N·m, 145 N·m, 150 N·m, 155 N·m, 160 N·m, 165 N·m, 170 N·m, 175 N·m, 180 N·m, 185 N·m, 190 N·m, 195 N·m, 200 N·m, 205 N·m, 210 N·m, or any value or any range between any two adjacent values ​​mentioned above.

[0073] For example, T may be 190 N·m±5 N·m.

[0074] For another example, T may be greater than or equal to 130 N·m and less than 190 N·m, or T may be greater than 190 N·m and less than or equal to 210 N·m.
