Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1-6, an integrated intelligent automatic shift-by-wire device comprises a controller 1 and an actuating mechanism 2, wherein the actuating mechanism 2 comprises a shell 21, a motor 22, a speed reducing mechanism 23, a transmission mechanism 24 and an output shaft 25, wherein the motor 22 is decelerated by the speed reducing mechanism 23 and drives the output shaft 25 to rotate and shift gears through the transmission mechanism 24, and the controller 1 for controlling the motor 22 to drive is arranged in the shell 21.
The shell 21 comprises a lower shell 212 and an upper shell 211 covered on the lower shell 212, a plug 213 used for connecting the wiring of the motor 22 with the external wiring of the controller 1 is arranged on the side wall of the lower shell 212, the plug 213 is used for connecting the external wiring with the wiring of the controller 1 and the wiring of the motor 22, the plug 213 is connected with a jack through a contact pin in a contact manner, and a contact pin with a round-head rectangular hole is arranged on the jack.
The transmission mechanism 24 comprises a worm wheel 241 and a worm 242 meshed with the worm wheel 241 for transmission, the worm wheel 241 is a sector gear, and the lower shell 212 is provided with a limiting rib 214 for limiting the worm wheel 241.
The speed reducing mechanism 23 comprises a pinion 231 and a large gear 232 which are meshed with each other, the pinion 231 is arranged on the shaft of the motor 22, and the large gear 232 is fixedly connected with a worm 242.
The lower shell 212 is provided with a plurality of limiting convex columns 215, the controller 1 is provided with limiting holes 11 which are matched with the limiting convex columns 215, and the controller 1 is limited and installed in the lower shell 212 through the arrangement.
The motor 22 in the actuating mechanism 2 drives the output shaft 25 to rotate, the boss 32 presses down the pawl 3 to move towards the ratchet wheel 31 on the right in the drawing in the downward moving process, if the concave tooth of the ratchet wheel 31 is just positioned under the pawl 3, the pawl 3 buckles the ratchet wheel 31, and the ratchet wheel 31 cannot rotate and also fixes the vehicle due to the rigid connection of the ratchet wheel 31 and the output shaft 25, so that the purpose of parking is achieved; if the teeth on the ratchet wheel 31 are located below the pawl 3, said pawl 3 cannot catch into the teeth, and the pawl 3 cannot lock the ratchet wheel 31. However, the actuating lever 33 will move upwards to compress the spring behind the boss 32, the spring force of the boss 32 will continuously act on the boss 32, once the ratchet wheel 31 moves a little under the action of the gravity of the vehicle or other conditions causing the vehicle to shake, so that the pawl 3 is clamped into the concave teeth, the spring force of the boss 32 pushes down the boss 32 rapidly, the boss 32 pushes the pawl 3 into the concave teeth of the ratchet wheel 31 to lock the ratchet wheel 31, and the boss 32 spring is released.
In some special cases, the electric parking system cannot work normally, for example, when the automobile battery is not powered, the battery is damaged, the wiring harness is broken, the parking mechanism, the motor 22 and the control circuit are broken, the parked system cannot be released from the parking state and cannot be towed, the device has two simple manual devices, an operator can rotate the large gear 232, and the large gear 232 can drive the sector turbine to rotate so as to separate the pawl 3 in the transmission from the ratchet wheel 31.
One of the simple manual devices is to extend the end of the worm 242 to the outer end of the housing 21, and an operator can manually rotate the worm 242 by using a wrench, a screwdriver, or a hex key. For the convenience of water and dust resistance, the worm 242 may not extend directly out of the housing 21, but a spring-loaded interface simple device may be provided on the housing of the worm 242, just as a spare tool such as a small screwdriver. The worm 242 interfaces the standby tool with the housing in a watertight connection. In a natural state, the spring keeps the worm 242 interface backup tool out of contact with the worm 242, so when the worm 242 rotates, the worm 242 interface does not rotate, there is no resistance, and there is no wear. However, when the operator desires, a screwdriver, or finger, or other tool may be used to press the worm 242 against the interface backup tool, first overcoming the spring force and then contacting the worm 242. The male and female elements on the alternate interface tool then engage the male and female elements on the worm 242 so that torque can be transferred to the worm 242 to be rotated. When the operator releases, the worm 242 interface will move away from the worm 242 under the influence of the spring.
The upper housing 211 of the simple manual device is provided with a window 216, the window 216 is covered by an elastic transparent film to keep waterproof sealing, when an operator can press the sealing film by hand and touch the large gear 232, the operator only needs to push the large gear 232 towards the unlocking direction through the elastic transparent film to achieve the parking release state, when the operator releases the hand, the elastic transparent film leaves the worm 242 under the action of elastic force, and meanwhile, the rotating result of the large gear 232 can be observed through the elastic transparent film.
The basic working principle of the invention is as follows:
An integrated intelligent drive-by-wire automatic gear shifting device can directly control a gear shift between an operating lever and an actuating mechanism 2 through one wire harness, and the purposes of simplifying design, reducing cost and improving reliability can be achieved because no transfer and no wire harness exist between the controller 1 and the actuating mechanism 2 and no time delay exists when gear shifting operation is controlled; the automatic gear shifting device has the parking releasing function, and specifically comprises 1. One end of the worm 242, which is close to the large gear 232, extends to the outer end of the shell 21, and parking 2 can be released by rotating the worm 242 through an external tool. A window 216 is arranged on the shell 21 above the large gear 232, the window 216 is covered by an elastic transparent film to keep waterproof sealing, when an operator can press the elastic transparent film by hand and touch the large gear 232, the operator only pushes the large gear 232 towards the unlocking direction through the elastic transparent film so as to achieve the parking releasing state, and when the operator releases the hand, the elastic transparent film leaves the large gear 232 under the action of elasticity, and meanwhile, the rotating result of the large gear 232 can be observed through the elastic transparent film.
