Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
A propulsion mechanism 100 according to an embodiment of the present invention is described below with reference to fig. 1-6.
The propulsion mechanism 100 according to an embodiment of the present invention may include: the device comprises a mounting base 1, a driving motor 2, two transmission screw rods 3 and two moving supports 5.
As shown in fig. 1 to 6, a propulsion mechanism 100 according to an embodiment of the present invention is adapted to be mounted on a vehicle seat to be connected between a seat leg rest and a vehicle seat body, so as to adjust a supporting position and an angle of the seat leg rest by pushing the seat leg rest to move relative to the vehicle seat body, so as to increase a leg supporting area of a passenger, thereby being capable of supporting the lower leg of the passenger better, and further improving a riding comfort of the vehicle seat. In addition, the propulsion mechanism 100 according to the embodiment of the present invention may also be applied to other engineering machine application scenarios.
Because traditional advancing mechanism is great to arranging the space demand, and in engineering machine tool, for example on vehicle seat, advancing mechanism's arrangement space is limited, consequently leads to advancing mechanism's spatial arrangement difficulty, the length that the advancing mechanism who installs on vehicle seat can stretch out is shorter, causes the seat leg to hold in the palm the support area less to passenger's shank, can't effectual bearing passenger's shank to can't satisfy vehicle seat's comfort level demand, lead to vehicle seat's riding comfort relatively poor.
To this end, the embodiment of the present invention designs a longer propulsion mechanism 100 that is more compact, requires less space for deployment, and is capable of being extended as a whole. From this for propulsion mechanism 100 can be elongated longer in compact arrangement space, thereby make propulsion mechanism 100 can satisfy the support length demand that seat leg held in the palm the travelling comfort, and then make seat leg hold in the palm the shank that can effectual bearing passenger, so that improve vehicle seat's riding comfort.
Wherein, driving motor 2 is fixed on mounting base 1 to what make driving motor 2 can set up is more stable, and driving motor 2 has two power take off 21, and two power take off 21 homoenergetic are outwards output power, with the two power of utilizing same driving motor 2 simultaneously outwards output, thereby avoid setting up unnecessary driving motor 2, so that advancing mechanism 100's overall structure is compacter, is more convenient for arrange. Alternatively, the drive motor 2 may also have more power outputs 21, and the plurality of power outputs 21 may be respectively located in different directions, so that the propulsion mechanism 100 can achieve elongation in various directions.
Further, two transmission screw rods 3 are respectively rotatably arranged on the mounting base 1, and two power output ends 21 are respectively in transmission connection with the two transmission screw rods 3 through two sets of gear transmission mechanisms 4, so as to realize primary transmission of the propelling mechanism 100. The two motion supports 5 are respectively in transmission connection with the two transmission screw rods 3, so that when the driving motor 2 operates, the two motion supports 5 can respectively move in opposite directions to realize the secondary transmission of the propulsion mechanism 100.
Specifically, one of two moving brackets 5 of the propulsion mechanism 100 on the vehicle seat is suitable for being connected to a vehicle seat body, and the other one of the two moving brackets is suitable for being connected to a seat leg support, and because the vehicle seat body is fixed on the vehicle, when the overall length of the propulsion mechanism 100 is changed, the position of the seat leg support relative to the vehicle seat body is also changed, so that the seat leg support can better lift the legs of a passenger, and the aim of improving the riding comfort of the passenger can be achieved.
That is, the extended length of the propulsion mechanism 100 is the length of the leg rest of the seat extended forward, and the longer the length of the propulsion mechanism 100 is extended, the greater the length of the leg rest of the seat extended forward, the greater the support area of the leg rest of the seat for the legs of the passenger, and the higher the riding comfort of the vehicle seat.
The driving motor 2 outputs driving torque through the power output ends 21 at both ends, and the output driving torque is adjusted to a proper speed and torque in the transmission process of the gear transmission mechanism 4 and then drives the transmission screw 3 to rotate, thereby completing the primary transmission of the propulsion mechanism 100. And the rotation of the driving screw 3 drives the movement of the moving bracket 5 connected to the driving screw 3 relative to the mounting base 1, thereby completing the secondary transmission of the propelling mechanism 100. From this, through the two-stage transmission structure of advancing mechanism 100, can satisfy the bigger extension length demand of advancing mechanism 100 in limited space to make advancing mechanism 100 can be elongated longer, thereby make the length that the seat leg rest extended forward bigger, so that the support area of seat leg rest to passenger's shank is bigger, and then the effectual riding comfort who has promoted vehicle seat.
Further, the movement of the moving bracket 5 relative to the mounting base 1 can make the moving bracket 5 extend out of the mounting base 1, so that the whole length of the propelling mechanism 100 can be extended longer, and the purpose of pushing the seat leg support to extend out of the vehicle seat body is achieved. Specifically, the length of the moving bracket 5 extending out of the mounting base 1 is the maximum displacement of the moving bracket 5 capable of moving on the drive screw 3, that is, the maximum length of the moving bracket 5 extending out of the mounting base 1 is L2 (see fig. 4).
Still further, both the moving brackets 5 of the pushing mechanism 100 can be extended outward to achieve a length of L2 extended outward twice as much as when the two moving brackets 5 are moved in opposite directions, respectively, so that the entire length of the pushing mechanism 100 can be extended longer to facilitate the long stroke movement of the pushing mechanism 100.
In addition, the driving motor 2, the two driving screws 3 and the two sets of gear transmission mechanisms 4 are all integrated on the same mounting base 1, so that the overall structure of the propelling mechanism 100 is more compact, the propelling mechanism 100 is integrally arranged to be smaller, and the mounting space required by the propelling mechanism 100 is smaller.
According to the propulsion mechanism 100 of the embodiment of the invention, the overall structure of the propulsion mechanism 100 is more compact, so that the occupied arrangement space is smaller, and the overall extending length of the propulsion mechanism 100 is larger, so that the propulsion mechanism 100 can extend longer in the compact arrangement space, and therefore, the support length requirement of the leg support comfort of the seat can be met, and the leg support of the seat can better support the lower leg of a passenger, so that the riding comfort of the vehicle seat can be improved.
With reference to the embodiments shown in fig. 1, fig. 3 and fig. 4, the two power output ends 21 are respectively located at the longitudinal ends of the driving motor 2, and the two driving screws 3 are respectively located at the transverse sides of the driving motor 2, so that the overall structural design of the propelling mechanism 100 is more reasonable, the overall structure of the propelling mechanism 100 is more compact, and the arrangement space occupied by the propelling mechanism 100 is smaller and more convenient to arrange.
Further, the setting extending directions of the two transmission screws 3 are respectively the same as the setting extending direction of the driving motor 2, that is, the driving motor 2 and the transmission screws 3 both extend along the longitudinal direction to occupy less space in the transverse direction, so as to further improve the structural compactness of the propulsion mechanism 100, and further reduce the arrangement space occupied by the propulsion mechanism 100.
Still further, because two motion support 5 move along two drive screw 3's extending direction respectively, consequently, with two drive screw 3 parallel arrangement, and set up two motion support 5 about driving motor 2 centrosymmetric, can make the relative motion distance between two motion support 5 of transmission connection on two drive screw 3 bigger, thereby make advancing mechanism 100's whole length can be elongated longer, thereby make the length that seat leg holds in the palm can stretch out forward bigger, and then make seat leg hold in the palm bigger to the support area of passenger's shank, so that promote the riding comfort of vehicle seat.

And the first transmission gear 41 is in mesh transmission with the second transmission gear 42, so that the second transmission gear 42 can obtain proper speed and torque by using the transmission ratio between the first transmission gear 41 and the second transmission gear 42, and further, the second transmission gear 42 is fixed on the transmission lead screw 3, so that the transmission lead screw 3 can synchronously rotate with the second transmission gear 42, and the transmission lead screw 3 can be driven by the driving motor 2 to rotate.
Specifically, the power take off end 21 at the both ends of driving motor 2 outputs the drive torque, transmission shaft 43 through both ends transmits the moment of torsion to the first drive gear 41 at both ends, first drive gear 41 meshes the transmission with second drive gear 42, make with the synchronous pivoted drive screw 3 of second drive gear 42 can obtain suitable speed and moment of torsion, because two motion support 5 that are connected with two drive screw 3 transmissions respectively with vehicle seat body and seat leg support are fixed respectively, consequently unable rotation, thereby make two drive screw 3 can drive two motion support 5 respectively and be translational motion on two drive screw 3, so that the passenger can control the extension length that the seat leg supported.
Further, since the two power output ends 21 output driving torque by the same driving motor 2, the rotation directions of the transmission shafts 43 at the two ends are the same, so that the rotation directions of the two first transmission gears 41 are the same, and further, the movement direction of the second transmission gear 42 engaged with the two first transmission gears 41 is the same as the rotation direction of the transmission screw 3 fixed to the second transmission gear 42, and therefore, the two transmission screws 3 need to be provided with threads in opposite directions, so that the two motion supports 5 respectively connected to the two transmission screws 3 in a transmission manner can move in opposite directions under the condition that the rotation directions of the two transmission screws 3 are the same.

The outer end of the transmission matching part 51 is fixedly connected with the connecting part 52, so that the connecting part 52 extends out of the mounting base 1, the connecting part 52 is conveniently connected with the seat leg support or the vehicle seat body, and the mounting base 1 can be effectively prevented from influencing the movement of the moving bracket 5.
As shown in fig. 1 to 6, a plurality of bushings 6 are disposed on the mounting base 1, the plurality of bushings 6 are disposed at two longitudinal ends of the mounting base 1, wherein the driving screw 3, the first driving gear 41 and the second driving gear 42 are rotatably engaged with the bushings 6, respectively, so that the driving screw 3, the first driving gear 41 and the second driving gear 42 can stably rotate relative to the mounting base 1, so as to improve the stability of the whole propulsion mechanism 100, and thus the process of the propulsion mechanism 100 pushing the seat leg rest is more stable.
