Description

Automobile tail door lock with snow load function

Technical Field

The utility model relates to an automobile parts, in particular to automobile tail door lock with snow carries function.

Background

After the automobile tail gate is unlocked, the gravity of the gate and the resistance of the mechanism are overcome by the elasticity of the sealing strip, so that the tail gate is kept in an unlocked state, but the resistance is not too large when the gate is closed, and the elasticity of the sealing strip cannot be too large, so that when the automobile tail gate is in a snow-covered condition, the elasticity of the sealing strip cannot keep the gate in an opened state, and the tail gate cannot be opened.

Chinese patent publication No. CN103061617A discloses an automobile tail door lock with snow load function, which comprises an upper cover plate, a lower cover plate and a lock body; the lock body includes a ratchet, a pawl, a secondary pawl, a snow load link and a shackle. The pawl and the ratchet wheel are pulled by the snow load connecting rod to be incapable of returning when in an unlocking state, and the lock body can be ensured to be always in an opening state even if the lock catch is not bounced open, so that the lock can be unlocked easily, and the pawl can be automatically released to be in a normal state after the lock catch leaves the lock groove, and the snow load connecting rod is very convenient and free to use.

However, the automobile tail gate lock with the structure is characterized in that the hook column of the pawl is hooked by the hook with a little elasticity on the connecting rod, and the hook on the connecting rod is slender and elastic, so that the elasticity of the hook can be influenced after being influenced by the ambient temperature, and the snow load function is unstable and volatile under the high-temperature environment.

Disclosure of Invention

An object of the utility model is to provide an automobile tail gate lock with snow carries function, its snow carries the function and does not receive ambient temperature's influence, especially snow carries the function under high temperature environment still stably effectively.

In order to achieve the above purpose, the technical scheme of the utility model is that:

an automobile tailgate lock with a snow-loading function, comprising: the ratchet wheel is a V-shaped or U-shaped body, and the bottom of the ratchet wheel is connected with the cover plate through a first rotating shaft pivot; one end part of the opening side of the ratchet wheel is provided with a clamping hook part; the middle part of the ratchet wheel is provided with a V-shaped or U-shaped groove for limiting the lock catch; one end of the pawl is connected to the cover plate through a second rotating shaft, the other end of the pawl is a hook part matched with the ratchet wheel hook part, and a stop block is convexly arranged on one side of the hook part on the upper end surface of the pawl; the snow-carrying connecting rod is a plate body and is arranged above the ratchet wheel and the pawl, one end of the snow-carrying connecting rod is connected to the cover plate through a third rotating shaft pivot, the end of the snow-carrying connecting rod is located on the outer side of the other end of the opening side of the ratchet wheel, the other end of the snow-carrying connecting rod is located above the ratchet wheel hook portion and the pawl hook portion, and a supporting arm matched with the pawl stop block is arranged at the end of the snow-carrying connecting rod.

Preferably, the stop block on the upper end surface of the pawl is L-shaped.

The utility model has the advantages that:

the utility model discloses an rely on the support arm on the connecting rod to hold the pawl, make it can not the return, do not rely on the elastic support pawl of material, also not receive ambient temperature's influence, consequently the utility model discloses the snow of this design carries the stable, difficult inefficacy of function.

fig. 2 is a bottom view of an embodiment of the present invention;

fig. 3 to fig. 6 are schematic views of usage states of the embodiment of the present invention.

Detailed Description

Referring to fig. 1-6, the utility model discloses an automobile tail door lock with snow carries function, include:

the ratchet 1 is a V-shaped or U-shaped body, and the bottom of the ratchet is connected with the cover plate through a first rotating shaft 11 in a pivot way; one end part of the opening side of the ratchet wheel 1 is provided with a clamping hook part 12; the middle part of the ratchet 1 is provided with a V-shaped or U-shaped groove 13 for limiting the lock catch 100;

one end of the pawl 2 is connected to the cover plate through a second rotating shaft 21, the other end of the pawl 2 is provided with a hook part 22 matched with the hook part 12 of the ratchet wheel 1, and one side of the hook part 22 on the upper end surface of the pawl 2 is convexly provided with a stop block 23;

snow carries connecting rod 3, be a plate body, set up in ratchet 1 and pawl 2 top, this snow carries connecting rod 3 one end through third pivot 31 pivot connection in apron, this end is located ratchet 1 opening side's the other end outside, this snow carries connecting rod 3 other end to be located ratchet 1 pothook portion 12 and pawl 2 hook portion 22's top, and, this tip establish one with pawl 2 dog 23 complex support arm 32.

Preferably, the stop 23 on the upper end surface of the pawl 2 is L-shaped.

The utility model discloses the working process:

fig. 3 → fig. 4, during the locking process, the lock catch 100 pushes the snow link 3 away to enter the ratchet 1 and is locked by the pawl 2, and at this time, the head of the snow link 3 is preloaded on the pawl 2.

Fig. 4 → fig. 5, pawl 2 rotates counterclockwise when unlocked, and the preloaded head of snow link 3 releases preventing pawl 2 from returning.

Fig. 5 → fig. 6, when the latch 100 is completely released, the snow link 3 returns to the state of fig. 3, no longer blocking the pawl 2 from returning, so the pawl 2 can return to the state of fig. 3.
