Abstract
The invention discloses an automatic shifter. Adjacent locking portions of semi-enclosed structures are arranged on a connection part connected with a shifting lever. An unlocking arm is arranged in a casing, and one end of the unlocking arm is hinged to the casing. When moving the shifting lever, the other end of the unlocking arm is switched in the two locking portions, and the shifting lever can be locked when the end of the unlocking arm reaches one locking portion. A controller is connected with the unlocking arm and controls the unlocking arm to rotate to unlock the shifting lever. The two locking portions correspond to a P gear and an N gear of the automatic shifter respectively. The design of the locking structure can ensure that only when a driver stamps on a brake to achieve unlocking can the P gear be shifted to an R gear or the N gear be shifted to the R gear, and thereby ensuring safety of a transmission and the whole vehicle and avoiding manual damage to the transmission.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figures 1 to 5, a kind of automatic gear shifting device, comprising: housing 1, gear level 2, link 3, unlocking arm 4, lock part and controller.Wherein, one end of gear level 2 to be placed in housing 1 and to be connected with link 3, and this gear level 2 can move in the passage on housing 1 to select gear.Lock part is semi-surrounding structure, and its quantity is two, respectively corresponding P gear and N gear, and these two lock parts are disposed adjacent on link 3, and when gear level 1 is positioned at P gear or N gear, corresponding lock part coordinates gear level 1 locking with unlocking arm 4.Unlocking arm 4 is placed in housing 1, one end and this housing 1 hinged.Moving gear shift bar 2, the other end of unlocking arm 4 can switch in two lock parts, and the end of this unlocking arm 4 is placed in one after a lock part, and gear level 2 can by locking.Controller is connected with unlocking arm 4, controls this unlocking arm 4 and rotates, unlocks gear level 2.Preferably, controller is solenoid valve 7, controls unlocking arm 4 rotate by the power on/off controlling this solenoid valve 7, and this body structure of solenoid valve is simple, and price is also lower.
A kind of embodiment, as shown in Figure 4 and Figure 5, two lock parts are the first groove 5 and the second groove 6, first groove 5 is P gear lock groove, and the second groove 6 is that N keeps off lock groove.First groove 5 and the second groove 6 share a sidewall, and the institute of the first groove 5 like this and the second groove 6 takes up space less, and being also convenient to unlocking arm 4 switches between, and structure is compacter.In addition, a sidewall of the first groove 5 also can be connected with a sidewall of the second groove 6.Further preferably, the longitudinal section of the first groove 5 is U-shaped, and its side (towards the side of reader in Fig. 5) is provided with the first opening; The longitudinal section of the second groove 6 is L shape, and its side (towards the side of reader in Fig. 5) is provided with the second opening, and the first opening and the second opening are in the same way; Sidewall vertical with the first opening on first groove 5 is connected with sidewall vertical with the second opening on the second groove 6.The object arranging above-mentioned opening is, on the one hand under the prerequisite guaranteeing the firm locking of gear level 2, alleviates link 3 as far as possible, and the locking end that unlocking arm 4 is convenient in the setting of opening on the other hand fits into the first groove 5 or the second groove 6.In addition, the mode that the first groove 5 is adjacent with the second groove 6 also can select sidewall vertical with the first opening on the first groove 5 to be connected to a sidewall with sidewall vertical with the second opening on the second groove 6.
Again further preferably, the bottom surface of the first groove 5 and/or the second groove 6 is arc, and the bottom surface of the first groove 5 is near one end of the bottom surface of the second groove 6 higher than the bottom surface of the second groove 6, and the locking end being convenient to unlocking arm 4 slides into and skids off.
A kind of embodiment, as shown in Figure 5, unlocking arm 4 is L-shaped, and its bending end (locking end) can switch in the first groove 5 and the second groove 6.Unlocking arm 4 is designed to its bending end of L shape and relatively slightly weighs, and under gravity, more easily slides into lock part.Preferably, when the bending end of unlocking arm 4 is placed in the first groove 5, the bending end of unlocking arm 4 and the gap of each sidewall of the first groove 5 are 2 ± 1mm.When the bending end of unlocking arm 4 is placed in the second groove 6, the bending end of unlocking arm 4 and the gap of each sidewall of the second groove 6 are 2 ± 1mm.
As shown in Figure 4, when gear level 2 is positioned at P gear, unlocking arm 4 is placed in the first groove 5, the bending end of unlocking arm 4 and the gap of each sidewall of the first groove 5 are 2 ± 1mm, need first to move to the right, when movement travel can eliminate gap more than during 2 ± 1mm if now gear level 2 keeps off when direction promotes to the R shown in Fig. 1.Now the side of the first groove 5 contacts completely with unlocking arm 4, and continuing 2, moving gear shift bar cannot move, and need step on control for brake solenoid valve 7 and make unlocking arm 4 rotate out the first groove 5, can hang R gear after unblock.
As shown in Figure 5, when gear level 2 is positioned at N gear, unlocking arm 4 is placed in the second groove 6, and the bending end of unlocking arm 4 and the gap of each sidewall of the second groove 6 are 2 ± 1mm, if now gear level 2 keeps off direction promotion, when movement travel can eliminate gap more than during 2 ± 1mm to the R shown in Fig. 1.Now the side of the second groove 6 contacts completely with unlocking arm 4, and continuing 2, moving gear shift bar cannot move, and need step on control for brake solenoid valve 7 and make unlocking arm 4 rotate out the first groove 5, can hang R gear after unblock.
The design of above-mentioned keying structure can be guaranteed only to step on braking driver, can realize P gear and be linked into R gear or N gear is linked into R gear, thus ensure that the safety of speed changer and car load, avoiding people for causing transmission failure after unblock.
In sum, content of the present invention is not limited in the above-described embodiments, and those skilled in the art can propose other mode of execution easily according to guiding theory of the present invention, and these mode of executions all comprise within the scope of the present invention.
