Examples
As shown in fig. 1 and 2, the present invention provides a foldable intelligent steering wheel, which is applied to an intelligent vehicle. Folding intelligent steering wheel includes steering wheel main part 1 and liquid crystal display 2. A left grab handle 3 is arranged on the left side of the steering wheel main body 1 in a sliding way, a right grab handle 4 is arranged on the right side of the steering wheel main body 1 in a sliding way, and a folding mechanism 5 connected with the grab handle is arranged in the steering wheel main body 1 and used for driving the grab handle to move and fold along the horizontal direction.
As shown in fig. 3, the folding mechanism 5 includes a straight link 51 and a first transmission member 52 shaped like a "T". The middle of the cross bar of the first transmission member 52 is rotatably connected to the inside of the steering wheel main body 1 through a first rotating shaft 53. The straight link 51 has one end hinged to the sliding end of the handle and the other end hinged to the end of the longitudinal rod of the first transmission member 52. A first gear 54 is fixedly connected to the first rotating shaft 53, a second gear 55 is further arranged on one side of the first gear 54, and a first chain 56 is arranged to be sequentially sleeved on the first gear 54 and the second gear 55 in a meshing transmission manner. The second gear 55 is coaxially provided with a third gear 561. The left grab handle 3 and the right grab handle 4 are respectively connected with a group of folding mechanisms 5, and a third gear 561 at the left grab handle 3 side is meshed with a third gear 561 at the right grab handle 4 side. Therefore, by applying the gear transmission and chain transmission principle, when the left grab handle 3 or the right grab handle 4 moves and folds towards the steering wheel main body 1, the other grab handle group is driven by linkage to move and fold towards the steering wheel main body 1 synchronously.
An assist grip mechanism 6 is also provided on the steering wheel main body 1. The auxiliary handle mechanism 6 includes a lower handle 61, an "L" shaped link 62, and a "T" shaped second transmission member 63. The lower grip 61 is slidably disposed at a lower side of the steering wheel main body 1. The second transmission member 63 is disposed between the first transmission member 52 on the left handle 3 side and the first transmission member 52 on the right handle 4 side, and the second transmission member 63 is located at the bottom side of the first transmission member 52. The second gear 55 and the third gear 561 are rotatably connected to the inside of the steering wheel main body 1 via the second rotating shaft 57, and the middle of the cross bar of the second transmission member 63 is fixedly connected to the second rotating shaft 57 on the side of the right grab handle 4. One end of the L-shaped connecting rod 62 is hinged at the sliding end of the lower grab handle 61, and the other end is hinged at the tail end of the longitudinal rod of the second transmission member 63. By adopting the structure and applying the gear transmission and chain transmission principle, when the left grab handle 3 or the right grab handle 4 moves and folds towards the steering wheel main body 1, the other two groups of grab handles can be driven in a linkage way to move and fold towards the steering wheel main body 1 synchronously.
As described above, the inside of the steering wheel main body 1 is formed with the cavity for the folding mechanism 5 to be installed, and the side wall of the steering wheel main body 1 is provided with the sliding hole for the sliding end of the handle to be fitted into the cavity. The left grab handle 3 and the right grab handle 4 are both in a C-shaped structure with the opening facing the steering wheel body 1, and the C-shaped openings of the left grab handle 3 and the right grab handle 4 are respectively wedged with the corresponding side of the steering wheel body 1. The lower grip handle 61 is a straight rod structure parallel to the lower side of the steering wheel main body 1. Wherein, the middle part of the handle is provided with a slide bar 7 which is vertical to the side wall of the steering wheel main body 1, one end of the slide bar 7 is integrated on the handle, and the other end is arranged in a cavity inside the steering wheel main body 1 along a slide hole and is connected with the transmission piece. The embodiments of the structure are applied to the left grip 3, the right grip 4, and the lower grip 61, respectively. Preferably, the front disc surface of the steering wheel main body 1 is of a detachable installation structure, so that structural failure is caused by jolting, impacting and the like in the vehicle, and a driver can manually repair the steering wheel.
Specifically, on the right side: when the slide rod 7 of the right grip 4 moves into the steering wheel body 1, the first transmission member 52 of the right grip 4 is driven to rotate clockwise by the straight link 51 of the right grip 4. Further, the first gear 54 on the right grip 4 side rotates clockwise, and the first gear 54 on the right grip 4 side drives the second gear 55 on the right grip 4 side to rotate clockwise through the first chain 56 on the right grip 4 side, and the third gear 561 on the right grip 4 side and the second gear 55 on the right grip 4 side are coaxial and also rotate clockwise;
on the left side: when the sliding rod 7 of the left grab handle 3 moves into the steering wheel body 1, the straight link 51 on the left grab handle 3 side drives the first transmission piece 52 on the left grab handle 3 side to rotate counterclockwise. Further, the first gear 54 on the left handle 3 rotates counterclockwise, and the first gear 54 on the left handle 3 drives the second gear 55 on the left handle 3 to rotate counterclockwise through the first chain 56 on the left handle 3, and the third gear 561 on the left handle 3 is coaxial with the second gear 55 on the left handle 3 and also rotates counterclockwise;
through the above folding manner, the second transmission member 63 is further driven to rotate clockwise, and the "L" shaped link 62 is pulled, so as to pull the sliding rod 7 of the lower grip 61 to move towards the steering wheel main body 1.
Meanwhile, because the third gear 561 on the left grab handle 3 side and the third gear 561 on the right grab handle 4 side are engaged with each other, the effect of pushing the left grab handle 3 or the right grab handle 4 into the steering wheel body 1, namely, the effect of contracting the other two grab handles in a linkage manner can be realized, and finally the left grab handle 3, the right grab handle 4 and the lower grab handle 61 are contracted in place at the same time.
Further, in order to ensure stable operation of the folding mechanism 5 and the assist grip mechanism 6, fourth gears 58 are rotatably connected to the end portion of the slide bar 7 disposed inside the steering wheel main body 1 and both ends of the cross bar of the transmission member, respectively, and the three fourth gears 58 are disposed in a common horizontal line. And a second chain 59 is arranged and sequentially sleeved on the three fourth gears 58 in a meshing transmission mode. The embodiments of the structure are applied to the left grip 3, the right grip 4, and the lower grip 61, respectively. And the end of the straight link 51 or the "L" shaped link 62 near the grip is hinged on the end of the slide bar 7 placed inside the steering wheel main body 1. By this constructive way, when the handgrip is in the fully extended condition (see fig. 2), the three fourth gears 58 prop open the second chain 59 and constitute a triangular structure; when the handle is in the fully retracted state (refer to fig. 3), the second chain 59 is in a linear configuration on the three fourth gears 58. The first chain 56 and the second chain 59 are both flexible belt chains, and the handle can be stably folded or unfolded by using the gear transmission and chain transmission principles.
As mentioned above, the left grab handle 3, the right grab handle 4 and the lower grab handle 61 are respectively sleeved with the rubber soft sleeve 8,
one preferred embodiment is: as shown in fig. 4, the slide bar 7 is a square bar structure, a receiving groove 71 is opened on the top surface of the slide bar 7 at the right grip 4 side, and a pin 72 is placed in the receiving groove 71. In addition, a positioning hole 73 is arranged on the top surface of the sliding rod 7 at the side of the right grab handle 4, and a pin 72 is freely inserted into the positioning hole 73. The positioning hole 73 is arranged close to the end part of the slide rod 7 arranged inside the steering wheel main body 1, so that in a manual driving mode of a driver, the pin 72 is inserted into the positioning hole 73 to prevent the slide rod 7 of the right grab handle 4 from moving towards the steering wheel main body 1, so that the safety function is achieved, and the danger brought to driving by 'mistaken shrinkage' is avoided. If the steering wheel is to be retracted, the pin 72 is pulled out and placed in the receiving groove 71. Preferably, a string 74 is connected to an end of the pin 72, and an end of the string 74 remote from the pin 72 is fixed in the receiving groove 71, so that the pin 72 is prevented from being lost by connecting the pin 72 to the receiving groove 71 through the string 74.
One preferred embodiment is: as shown in fig. 1 and 5, a table 9 is provided on the front surface of the steering wheel main body 1 so as to cover the lower grip 61. The lower side edge of the table plate 9 is hinged on the lower side edge of the front panel surface of the steering wheel main body 1 through a hinge. A protrusion 11 is integrally formed on the upper side of the front panel of the steering wheel body 1, and a snap ring 91 capable of being snapped on the protrusion 11 is connected to the middle of the upper side of the table 9 to form a snap structure (refer to fig. 6). Therefore, through the arrangement of the structure, when the table plate 9 is not used, the table plate 9 is combined on the front disc surface of the steering wheel main body 1, and the table plate 9 is fixed through the buckle structure; when the desk plate 9 is used, a driver only needs to pull the retaining ring 91 and turn down the desk plate 9 along the hinge, so that the desk plate 9 is put down for temporarily placing a notebook computer, a coffee cup and the like. Wherein, a supporting plate 92 is integrally formed at the middle part of the lower side on the front plate surface of the desk plate 9. The support plate 92 is embedded in the table board 9, the support plate 92 is of an arc-shaped plate structure, and a protrusion is formed at the lower side edge of the front plate surface of the table board 9 to the front side. The handle body of the lower grab handle 61 is provided with a clamping groove 611 for clamping the supporting plate 92 after the table plate 9 is turned downwards along the hinge. Therefore, after the table plate 9 is opened, the supporting plate 92 is clamped in the clamping groove 611 of the lower grab handle 61 to support the opened state of the table plate 9 and ensure the stability of the table plate.
As described above, the liquid crystal display 2 is installed on the front panel surface of the steering wheel main body 1, and the main control module is provided to link the liquid crystal display 2 and the control system of the intelligent vehicle, so that the main control module is used to obtain the basic driving information of the vehicle, and transmit the obtained basic driving information to the liquid crystal display 2 for display. Specifically, the liquid crystal display 2 is embedded on the front panel surface of the table 9, and the liquid crystal display 2 is arranged close to the upper side edge of the table 9, so that when the table 9 is in a closed state, a driver can observe basic driving information and behavior state information of the vehicle through the liquid crystal display 2.
