Description of the invention: * [Technical field to which the invention pertains] ′ I invention relates to a parking mechanism, in particular, a parking mechanism suitable for absorbing impact forces to avoid damage to the shifting gear and the parking gear. 5 [Prior Art] When the vehicle is parked, a parking mechanism is used as a means to prevent the vehicle from moving. 1 is a cross-sectional view of a conventional parking mechanism, in which a conventional 10 parking mechanism 9 is assembled in an engine box 8 of a vehicle, and the parking mechanism 9 includes a rotating shaft 91 parking gear 92 and a shifting gear 93. The rotating shaft 91 is pivotally disposed in the engine box 8 , and the parking gear % is slidably disposed on one of the flanges 81 of the engine box 8 , and the shifting gear 93 is coaxially slidably disposed on the rotating shaft 9 . Please refer to FIG. 1 and FIG. 2 as a perspective view of a conventional parking gear and a shifting gear. The two sides of the parking gear 92 are respectively axially outwardly convexly provided with three external protrusions 92 and three internal convexities. Block 922, three outer bumps ... are respectively engaged with the engine 粕 8 ', and the shift gear 93 is axially outwardly convex with three engaging blocks 931 °. Therefore, when the vehicle is parked, the shift is made. The gear 93 slides on the rotating shaft 91 toward the parking gear 92, and the three engaging blocks 931 of the shifting gear 93 are respectively engaged with the three inner protrusions 922 of the parking gear 92, so that the rotating shaft 91 does not rotate. In order to achieve the purpose of parking. However, the engaging faces 923, 933 of the engaging block 931 of the conventional shifting gear 93 and the inner projection 922 of the parking gear 92 are vertical faces (perpendicular to the 5 1321623 shifting gear 93 and the parking gear 92, respectively), as shown in the figure. 2, so when the vehicle is parked on the roadside and the parking mechanism 9 is activated, if other vehicles inadvertently hit at this time, the impact force (external force) will be linked to the parking mechanism 9 in the vehicle, and then interlocked and acted upon Since the engine box 8' has a vertical surface as the engaging surface 923, the male gear is arranged in such a manner that the shifting gear 93 and the parking gear are separated from each other by the impact force, that is, the impact force is hard to change. Gear gear magic: The hard gear is generated between the parking gear 92 (the rotation of the shaft 91 causes a torsion situation, so that the shift gear 93 and the parking gear 92 are easily damaged. 10 15 20 == The effect, „, the result of hard twisting will also cause the engine phase 8 to be damaged, which is not very ideal. [Summary of the Invention] The parking mechanism of the present invention is set in a single, m crystal and 仏" engine phase, and the engine compartment And a ring flange, The ringing mechanism of the present invention includes a rotating shaft, a parking wheel, a changing gear, and a return spring.

If the surface is set to 5, the first engagement slope and the second engagement slope may be regarded as Line contact. Of course, the first engaging slope and the second engaging slope can also be spherical surfaces corresponding to each other. If the spherical surface is designed, the first engaging slope and the second engaging slope can be regarded as point contact. 10 [Embodiment] 3 is a cross-sectional view of a parking mechanism according to a first preferred embodiment of the present invention, wherein a parking mechanism 6 is assembled in a engine compartment, and wherein the engine compartment 1 includes two sliding slots ij (in view of the figure) 3 is a cross-sectional view, so that only the upper and lower chutes U) and a ring flange 12 can be displayed. The ring flange 12 has a recess 13 around the circumference 15. 3 and FIG. 4 are perspective views of the gearbox and the shifting gear of the first preferred embodiment of the present invention, wherein the parking mechanism 6 includes a rotating shaft 2, a parking gear 3, and a change. The gear 4 and the return spring S 〇20 are axially extended into the recess 13 surrounded by the engine box rim flange 12 and pivoted in the engine box t while the parking teeth (6) The shaft is axially slidably disposed on the ring flange 12 of the engine box 1, and the parking gear 3 includes an outer side surface 31, and an inner side surface 32' of which the inner side surface 32 is located on the opposite side of the outer side surface 31, 8 8 I52lb25, and The outer side surface 31 of the parking gear 3 is axially convexly provided with three sliders 311', which are respectively slidably disposed in the three chutes 11 of the 3 丨 箱 箱, respectively, and are respectively axially opposite to the three chutes 11 The inner side surface 32 of the parking gear 3 is axially recessed with three grooves 321 , and each of the two sides of the groove 321 defines a fifth two-inclined slope 322 . In the present embodiment, the ring flange 12 of the engine box includes a stop block 121' that is blocked from the inner side 32 of the parking gear 3, so that the parking gear 3 is axially slidably disposed in the ring of the engine box i. When the rim 12 is on, the parking gear 3 does not fall off from the ring® flange 12. In addition, the shifting gear 4 in the drawing is coaxially slidably disposed on the rotating shaft 2 and rotates with the rotating shaft 2, and the shifting gear 4 includes a side surface 41 which faces the inner side surface 32 of the parking gear 3, and the shifting gear The two side faces 41 are axially convexly disposed with three engaging blocks 411 respectively corresponding to the two grooves 321 of the inner side surface 32 of the parking gear 3, and the two sides of each of the engaging blocks 411 respectively extend 15 A snap-sloping slope 412 corresponding to the second engaging slope 322 on both sides of each groove 321 respectively. In the present embodiment, the first engaging slope 412 of each of the engaging blocks 411 and the second engaging slope 322 of each of the grooves 321 are inclined planes corresponding to each other, so that the design of the inclined surface can be utilized. A surface contact is formed between the first engagement slope 412 and the second 20 engagement slope 322. Further, in the present embodiment, the three engaging blocks 41 i of the shifting gear 4 are distributed at equal angles on the shifting gear 4, and the three grooves 321 of the parking gear 3 are equally distributed on the parking gear 3. 9 1321623 Further, the return spring 5 in the drawing is axially abutted between the engine casing ι and the outer side 31 of the parking gear 3, and resets the ridge 5 and has an axial reset preload. In this embodiment, the return spring 5 is material-compressed. Therefore, during the parking, the shifting gear 4 can be slid toward the parking wheel 3, and the three engaging blocks 411 are respectively engaged with the three grooves 321 and the first engaging slope 412 Corresponding to the second engagement oblique slope milk, respectively, so that the rotation of the shaft 2 can be restricted to achieve the purpose of parking. In the parking state, if the impact force (external force) is received, for example, when it is hit by another vehicle, the second engagement slope of the gear 3 is stabilized by the first engagement of the groove gear 4 If designed, the shifting gear 4 ... parking the car 3 can be easily temporarily detached. At this time, the (four) standard gear 4 has moved to one side of the parking gear 3 due to the shifting, so the replacement gear 4 will not Move, ^This 'parking gear 3 will slide axially on the ring convex (four) of the engine box 1 and temporarily disengage from the shift gear 4, so it can absorb the influence of the aforementioned impact force. When the parking gear 3 slides on the ring flange 12 of the engine (1) and temporarily shifts away from the gear 4, the axial resetting force of the return spring 5 abuts against the wheel 3 and enables the parking. The gear 3 slides axially on the ring flange 12 of the engine towards the indexing gear 4, so that the upper gear 21 of the parking gear can again engage with the change gear & block 411 and cause the shift The engaging block 411 of the gear 4 is again adapted to contact the second engaging inclined slope of the concave 21 of the parking gear 3, respectively, such that the parking condition can be resumed immediately. = The above-mentioned structure 'the shift gear 4 and the parking gear 3 are subjected to 'can be temporarily separated from each other' so as to prevent the impact force from being generated. 20 1321623 5 15 20 The shift gear 4 and the parking gear 3 are hard twisted with each other.
