Description

Shielding device

Technical Field

The present invention relates to a shielding device, and more particularly to a shielding device mounted on a vehicle to cover the vehicle.

Background

The vehicle needs to occupy a lot of space when parked, wherein the indoor parking lot can be shaded from the sun, shielded from the rain and has less dust, so parking the vehicle in the indoor parking lot is a better choice. However, the indoor parking lot is a building, which is expensive to construct, and thus the parking of the vehicle in the indoor parking lot is correspondingly expensive. Further, for the same reason, the number of parking spaces provided in an indoor parking place is still insufficient to be able to accommodate the number of existing vehicles. Therefore, many vehicles are still parked in open parking lots, and the vehicles are directly exposed to the sun, wind and rain, and may be exposed to sand storm in dry countries and snow in high-latitude countries.

In order to protect vehicles parked in open parking lots, a shielding device may be mounted on the vehicle, and the vehicle is covered with a cover cloth of the shielding device to separate the vehicle from the environment. In order to facilitate unfolding and storage, the cover is usually stored in the shielding device in a rolled manner, and when the shielding device is used, the cover is pulled out and spread out and hung on the edge of a vehicle to cover the vehicle. At the same time, the covering cloth is connected with a winding mechanism to provide elasticity to roll up the covering cloth so as to automatically retract the covering cloth into the shielding device when the covering cloth is separated from the edge of the vehicle. However, since the cloth is automatically rolled up, anyone can retract the cloth into the shade device.

Accordingly, there is a need in the art to provide a better solution to the above-mentioned problems.

Detailed Description

The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:

please refer to fig. 1 to fig. 3. The present invention provides a shielding device, which comprises a main body 10 and a lock 20. The main body 10 has a housing 11, a rotating mechanism 12 and a cover 13. The swing mechanism 12 is disposed in the housing 11 and has a rotatable spindle 121, and the spindle 121 has a rotor 122. The rotor 122 has a plurality of slots 1220 formed therein, the slots 1220 being arranged in a circle. In the present embodiment, the rotor 122 is fixedly disposed at one end of the spindle 121, and the slot 1220 is formed on an end surface of the rotor 122, but not limited thereto, for example, the rotor 122 may be disposed at a middle section of the spindle 121, and the slot 1220 is formed on an outer circumferential surface of the rotor 122.

One end of the mask 13 is fixed on the spindle 121, and the mask 13 is selectively wound on the spindle 121. The revolving mechanism 12 may further have a returning unit (not shown) connected to the spindle 121 for rotating the spindle 121. In the embodiment, the resilient unit is an elastic member, such as a torsion spring, which tends to drive the spindle 121 to rotate in a direction to wind the mask 13 around the spindle 121.

The lock 20 has a housing 21, a push post 22 and a lock barrel 23. The housing 21 is fixed to the housing 11. The housing 21 is formed with a through hole 210, and a protrusion 211 (see fig. 6) is formed to protrude inward inside the through hole 210.

The pushing column 22 movably penetrates through the housing 21, and specifically, can move along the length direction of the pushing column 22 relative to the housing 21 and rotate around a rotation axis parallel to the length direction. One end of the pushing column 22 is selectively engaged with the rotor 122. In the present embodiment, the pushing column 22 has a first column 221, a second column 222, a positioning element 223, an elastic element 224 and a knob 225.

The first cylinder 221 is disposed through the housing 21 and can move and rotate relative to the housing 21, and the first cylinder 221 has a body section 2211, a groove 2212, an annular flange 2213 and a connecting section 2214.

The body segment 2211 is disposed through the aperture 210 of the housing 21 and is selectively received in the aperture 210 of the housing 21. Please refer to fig. 6. The groove 2212 is located on the outer side of the body segment 2211, so that the groove 2212 is selectively received in the through hole 210 of the housing 21, and the protrusion 211 in the through hole 210 is received in the groove 2212. The groove 2212 extends along the length of the push post 22 and extends along the circumference of the push post 22 at an end adjacent to the swing mechanism 12. In other words, the groove 2212 is an L-shaped slot (see fig. 6).

The ring flange 2213 protrudes and surrounds the outer side of the body segment 2211, and in this embodiment is closer to the swing mechanism 12 than the groove 2212. The outermost side of the ring flange 2213 is the outer peripheral surface a, and the side of the ring flange 2213 away from the turning mechanism 12 is a ring slope b.

The connection segment 2214 is formed at one end of the body segment 2211 adjacent to the swing mechanism 12, and protrudes from an end surface of the end of the body segment 2211 toward the swing mechanism 12. The width of the connecting section 2214 is less than the width of the body section 2211. The connecting section 2214 is not circular in cross section but may be oval, polygonal, etc. In this embodiment, the cross section of the connecting segment 2214 is a circle with an upper segment and a lower segment, i.e. the connecting segment 2214 is a cylinder with two radial sides respectively forming a plane.

One end of the second post 222 is movably disposed on the first post 221, the other end is selectively engaged with one of the slots 1220, and an end surface of the other end is an inclined surface 2221, so that the other end of the second post 222 forms a wedge shape. Specifically, one end of the second cylinder 222 is sleeved on the connecting section 2214 of the first cylinder 221, and can move along the length direction of the pushing column 22 relative to the connecting section 2214.

The second post 222 is formed with a sliding slot 2222 (see fig. 4) and at least one elongated slot 2223. The sliding slot 2222 is formed on an end surface of the second post 222 away from the rotation mechanism 12, and is recessed inward from the end surface to extend along the length direction of the pushing post 22. The connecting section 2214 of the first cylinder 221 is received in the sliding slot 2222. At least one long groove 2223 is recessed inward from the outer side surface of the second cylinder 222 to communicate with the sliding groove 2222, and the at least one long groove 2223 extends along the length direction of the push column 22. In this embodiment, two long slots 2223 are formed on two opposite sides of the second column 222, and the two long slots 2223 are formed on two opposite sides of the second column 222.

The positioning element 223 is fixedly disposed on the connecting section 2214 of the first cylinder 221, and at least one end of the positioning element 223 is received in the at least one long slot 2223. In this embodiment, the positioning element 223 is fixedly disposed through the connecting section 2214, and two ends of the positioning element 223 protrude outward from the outer side surface of the connecting section 2214 and are respectively received in the two long slots 2223. By the positioning member 223, the second cylinder 222 does not separate from the first cylinder 221 when moving relative to the first cylinder 221.

Two ends of the elastic element 224 of the pushing post 22 are respectively connected to the first column 221 and the second column 222, and the second column 222 is inclined to engage with the engaging slot 1220. In the present embodiment, the elastic element 224 of the pushing column 22 is a compression spring, and two ends of the compression spring respectively abut against the first column 221 and the second column 222. The knob 225 is disposed on an end of the body 2211 away from the rotation mechanism 12 and exposed out of the housing 21 for operating the pushing column 22.

The lock core 23 is disposed on the housing 21 and selectively engaged with the push post 22, and in this embodiment, the lock core 23 selectively abuts against the outer peripheral surface a or the ring inclined surface b of the ring flange 2213 of the push post 22. Specifically, the lock core 23 is accommodated in the housing 21 of the lock device 20, and has a movable shaft 231, a plurality of rollers 232, and an elastic member 233.

One end of the movable shaft 231 is a pushing end, which selectively abuts against the outer circumferential surface a or the ring inclined surface b of the ring flange 2213 of the pushing column 22. In the embodiment, the pushing end is a block, and a pushing inclined surface 2310 is formed on the pushing end, and the pushing inclined surface 2310 selectively pushes against the outer peripheral surface a or the ring inclined surface b of the ring flange 2213 of the pushing column 22. The plurality of wheels 232 are partially exposed out of the housing 21 and rotatably sleeved on the movable shaft 231. The elastic member 233 of the lock core 23 is connected to the pushing end of the movable shaft 231, and the pushing end is inclined to abut against the pushing post 22.

Thus, when each of the rotating wheels 232 rotates to a predetermined position, the lock core 23 is in an unlocked state, so that the movable shaft 231 can slide on the outer peripheral surface a or the ring inclined surface b of the ring flange 2213, so as to change the abutting position of the abutting end of the movable shaft 231. When a rotating wheel 232 is not at the predetermined position, the rotating wheel 232 is engaged with the movable shaft 231, so that the movable shaft 231 cannot move and is engaged with the first cylinder 221 of the pushing column 22.

Please refer to fig. 1, fig. 4 and fig. 5. When the rotor is stationary, the end of the second post 222 of the pushing post 22 is engaged with the engaging groove 1220 of the rotor 122. When the user wants to open the covering cloth 13, since the end surface of the second column 222 of the pushing-against column 22 is the inclined surface 2221, when the user pulls the covering cloth 13 to drive the rotor 122 to rotate, the edge of the slot 1220 of the rotor 122 pushes against the inclined surface 2221 of the second column 222 to push the second column 222 to move toward the first column 221.

When the mask 13 is pulled to a predetermined position, the user can no longer apply a force on the mask 13, and the spindle 121 and the rotor 122 rotate back because the spindle 121 is connected to the return unit. However, since the elastic member 224 of the pushing post 22 continuously pushes the second post 222 toward the rotor 122, the second post 222 rotates only a little to be caught in the nearest catching slot 1220 when the rotor 122 rotates back. At this time, the edge of the slot 1220 pushes against the back of the inclined surface 2221 of the second post 222, and cannot push the second post 222 through the inclined surface 2221, so that the second post 222 is engaged with the rotor 122, and the rotor 122 does not rotate any more. Thereby, the blind 13 is only slightly rolled back and does not completely roll back onto the turning mechanism 12. In other words, the inclined surface 2221 of the second cylinder 222 can limit the unidirectional rotation of the rotor 122.

Please refer to fig. 6 and fig. 7. When the user wants to store the covering cloth 13, the rotating wheel 232 of the lock cylinder 23 is rotated to make the rotating wheel 232 located at a predetermined angle, so that the lock cylinder 23 is in an unlocked state. At this time, the movable shaft 231 can move along the length direction thereof, and the user can pull the pushing post 22 outwards, and rotate the pushing post 22 after pulling the pushing post 22 outwards, so that the protrusion 211 in the through hole 210 is accommodated at the end of the L-shaped groove 2212, and the pushing post 22 is completely separated from the rotor 122 and kept in the separated state from the rotor 122. Thus, in addition to automatically winding the blind 13 back, it is more labor-saving to pull the blind 13 open in this state.

At this time, the block at the pushing end of the lock core 23 abuts against the outer peripheral surface a of the ring flange 2213 of the pushing column 22. When the push post 22 is rotated back and pushed back into place, the block is slid by the outer circumference a of the ring flange 2213 against the ring slope b of the ring flange 2213. Then, as long as the user randomly rotates any one of the rotating wheels 232, the lock core 23 returns to the locked state, and the block body locks the annular flange 2213, so that the pushing column 22 cannot be pulled out again. In other words, when the lock core 23 engages the push post 22, the push post 22 also engages the spindle 121.

In summary, the shielding device of the present invention has a lock 20, and the lock 20 can lock the shielding cloth 13, so that the shielding cloth 13 can only be opened but not be folded in the locked state. Therefore, after the user wraps his or her vehicle with the covering cloth 13, the covering cloth 13 is kept in a state of covering the vehicle even if other people uncover the covering cloth 13, and the vehicle can be continuously protected without being automatically rewound.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
