Description

Technical Field

[0001] The present invention relates to a cover unlocking mechanism for a blind, and in particular to a cover unlocking mechanism applied to a side end of a curtain fabric shaft tube of the blind, so that the curtain fabric shaft tube can generate locking and unlocking functions in a body side wall of a motor vehicle. Background Art

[0002] A covering curtain is a product used in motor vehicles to provide a shielding function for the rear storage space of the vehicle body. Existing covering curtains mainly connect curtains with a retractor in a curtain shaft tube, and the curtain can be pulled out of the curtain shaft tube and unfolded through the retractor, and the unfolded curtain can be automatically retracted into the curtain shaft tube. In order to enable the covering curtain to be assembled in the vehicle body, the covers at both ends of the curtain shaft tube are respectively locked in the two side walls of the rear storage space of the vehicle body through the cover snap mechanism, so that the curtain of the covering curtain can be unfolded by the user, and then the positioning protrusions at both ends of the curtain tail plate at the rear end of the curtain are snapped into the two side walls of the rear side of the rear storage space of the vehicle body, so that the curtain can be unfolded and positioned, providing a shielding function for the rear storage space of the motor vehicle body.

[0003] When the conventional blind is assembled on the vehicle body, the buckle mechanism in the covers at both ends of the curtain shaft tube that can be retracted along the center line is fixed to the buckle grooves on the two side walls of the rear storage space of the vehicle body, so that the curtain shaft tube can be assembled and set between the two sides of the vehicle body. Although the buckle mechanism installed in the cover can use the buckle mechanism that can be retracted along the center line to enable the curtain shaft tube and the side wall of the vehicle body to have the function of locking and unlocking, during the operation of installing or removing the curtain shaft tube, the operator must forcibly compress the buckle mechanism in the cover along the center line of the curtain shaft tube to unlock it, which is laborious during the disassembly of the blind.

[0004] In order to solve the aforementioned problem of laborious operation, the currently existing cover adopts a rotating unlocking buckle mechanism to provide the user with a more labor-saving operation method. However, the overall composition of the rotating unlocking buckle mechanism is relatively complex in structure, and during the locking and unlocking operation of the rotating unlocking buckle mechanism arranged in the cover, the user must turn the knob to drive the fixed block to perform the locking and unlocking actions, which still has the problem of inconvenient operation. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cover unlocking mechanism for a covering curtain, so as to solve the problems of the existing rotating unlocking buckle mechanism having a complex structure and inconvenient operation.

[0006] The technical solution proposed by the present invention is to provide a cover unlocking mechanism for a covering curtain, which is used to be installed in the cover at the end of the curtain fabric shaft tube of the covering curtain, and the peripheral wall of the cover forms an accommodating space, and the peripheral wall has a first side plate and a second side plate adjacent to each other, wherein:

[0007] A first through hole connected to the accommodating space is provided in the first side plate of the cover, a second through hole connected to the accommodating space is provided in the second side plate, a first pivoting portion is provided on a side of the first through hole away from the second through hole, and a second pivoting portion is provided on a side of the second through hole away from the first through hole;

The pressing block and the fixing block can be linked by the elastic deformation and recovery of the spring piece, so that the cover unlocking mechanism has a linked locking and unlocking function.

[0009] In the cover unlocking mechanism of the covering curtain as described above, one side of the pressing block is a first pivot end, and the pressing block is pivotally connected to the first pivot part with the first pivot end, and the other side of the pressing block relative to the first pivot end is a first movable end, and the pressing block can rotate around the first pivot part so that the first movable end of the pressing block can protrude out of the first side plate of the cover, and the pressing block can be pressed and retracted into the first side plate; one side of the fixed block is a second pivot end, and the fixed block is pivotally connected to the second pivot part with the second pivot end, and the other side of the fixed block relative to the second pivot end is a second movable end, and the fixed block can rotate around the second pivot part so that the second movable end of the fixed block can extend out of the second side plate of the cover and retract into the second side plate; the spring sheet includes an elastic deformation section, and the two ends of the elastic deformation section are respectively a first connecting end and a second connecting end, the first connecting end is connected to the first movable end of the pressing block, and the second connecting end is connected to the second movable end of the fixing block.

[0010] In the cover unlocking mechanism of the blind as described above, the spring sheet is a V-shaped spring sheet, and the elastic deformation section of the spring sheet forms a bending portion, which extends in a direction away from the pressing block and the fixing block.

[0011] In the cover unlocking mechanism of the blind as described above, the spring piece is a W-shaped spring piece, and the elastic deformation section of the spring piece forms a plurality of continuously bent portions.

[0012] In the cover unlocking mechanism of the blind as described above, the elastic deformation section of the spring sheet forms an arc portion, and the arc portion extends in a direction away from the pressing block and the fixing block.

[0013] In the cover unlocking mechanism of the blind as described above, the pressing block forms a first stopper at the end edge of the first movable end located in the first side plate, and the fixing block forms a second stopper at the end edge of the second movable end located in the second side plate.

[0014] In the cover unlocking mechanism of the blind as described above, either one or both of the first pivoting portion of the pressing block and the second pivoting portion of the fixing block are connected to the peripheral wall of the cover in combination with a torsion spring.
