Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention and the accompanying drawings are combined together to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1 to 3, an embodiment of the present invention provides a mechanical sunshade device, which includes a bracket assembly 1, a sunshade plate 2, and a driving module; the driving module comprises a telescopic device 3, a telescopic rail 4, a telescopic bracket 5, a sliding component 6, a first spring 7 and an opening and closing mechanism; the telescopic device 3 is arranged on the bracket assembly 1 and can move outwards in a jacking mode; the telescopic rail 4 is fixedly arranged on the bracket assembly 1 along the top extension direction of the telescopic device 3, and the telescopic bracket 5 is connected with the telescopic rail 4 in a sliding way; a sliding rail 8 arranged along the extension direction of the extension device 3 is arranged on the extension bracket 5, the sliding member 6 is connected with the sliding rail 8 in a sliding manner, the sliding member 6 is connected with the movable end of the extension device 3, and a first spring 7 with the elasticity opposite to the top extension direction of the extension device 3 is arranged between the sliding member 6 and the extension bracket 5; the back side of the sun visor 2 is hinged to the front end of the telescopic bracket 5, and the back side of the sun visor 2 is drivingly connected to the slide member 6 through an opening and closing mechanism.

The utility model discloses a theory of operation is:

the telescopic device 3 pushes outwards, and drives the sliding component 6 to push outwards, and because the sliding component 6 and the telescopic bracket 5 have the resistance of the first spring 7, the sliding component 6 can drive the whole telescopic bracket 5 to slide outwards along the telescopic rail 4, and the sun shield 2 also slides outwards along the telescopic bracket 5, and forms a gap with the bracket assembly 1 for ventilation. If the user only needs ventilation, the telescopic device 3 can stop pushing.

If the sun visor 2 is to be opened further, the telescopic device 3 can be controlled to continue pushing forward. At this time, the telescopic bracket 5 has moved to the foremost position of the telescopic rail 4 for limiting, and cannot move forward, the sliding member 6 overcomes the resistance of the first spring 7 to move forward, and slides relative to the telescopic bracket 5, and drives the opening and closing mechanism to open the sun visor 2. The opening amplitude corresponds to the pushing amplitude of the telescopic means 3, and therefore this opening amplitude can also be controlled at will.

If the sun visor 2 is to be closed, the retractable device 3 is retracted backwards, and the closing movement is the reverse of the above movement, which is not described herein.

For the opening and closing mechanism, there are two preferred solutions. In this embodiment, as a first preferred scheme, the opening and closing mechanism includes a shift lever 9 and a first connecting rod 10; the middle part of the deflector rod 9 is hinged with the telescopic bracket 5, one end of the deflector rod 9 is connected with the sliding component 6, and the other end of the deflector rod 9 is hinged with the rear end of the first connecting rod 10; the middle part of the back side of the sun shield 2 is hinged with the front end of the telescopic bracket 5, and the end part of the back side of the sun shield 2 is hinged with the front end of the connecting rod.

The deflector rod 9 forms a fulcrum with the telescopic bracket 5 in the middle part to form a lever structure. When the telescopic device 3 pushes the sliding member 6 to slide forward relative to the telescopic bracket 5, the shift lever 9 swings and rotates around the hinge point at the middle part, and pulls the first link 10 to pull backward, so as to drive the sun visor 2 to open correspondingly.

Specifically, since the movement track of the shift lever 9 is an arc, the end of the shift lever 9 is preferably provided with a sliding slot extending along the length direction thereof, and the sliding member 6 is connected with the sliding slot. So that the sliding member 6 and the end of the shift lever 9 will not be dead against each other in the process that the telescopic device 3 pushes the sliding member 6 to slide forwards.

In order to further provide a more certain operation to the driving module, it is preferable that a second spring 11 having the same elastic force as the extending direction of the extending device 3 is provided between the extending bracket 5 and the bracket assembly 1. During the outward pushing of the telescopic device 3, the second spring 11 will provide the assisting force to push the whole telescopic bracket 5 to slide forward. Therefore, the phenomenon that the sliding action of the telescopic bracket 5 is blocked due to unsmooth sliding of the telescopic rail 4 is avoided, and the working rhythm of the whole driving module is influenced.

Preferably, the telescopic device 3 is an electric push rod with a driving motor. The electric push rod has the advantages of stable transmission, mature structure and outward purchase. Of course, the telescopic device 3 may also adopt other structures such as a linear motor, a belt drive or a chain drive, but the electric push rod is undoubtedly the most volume-saving and structure-simplifying scheme from the viewpoint of device simplification.

It should be noted that although the drawings show the structure in which the drive module is placed on top, it is fully possible to place the drive module on the bottom in reverse. The sun visor 2 is therefore not restricted to being opened upwardly or downwardly.

Example two

The only difference between this embodiment and the first embodiment is the specific structure of the opening and closing mechanism.

Referring to fig. 4 to 6, in the present embodiment, preferably, the opening and closing mechanism includes a second connecting rod 12; the back end of the sun shield 2 is hinged with the front end of the telescopic bracket 5; the front end of the second link 12 is hinged to the back-side middle portion of the sun visor 2, and the rear end of the second link 12 is hinged to the slide member 6.

The second connecting rod 12 is directly adopted to directly transmit the jacking acting force of the telescopic device 3, and the force application direction and the jacking direction are the same, so that the sun shield 2 is supported. In the first and second embodiments, the hinge positions of the rear side of the sun visor 2 and the telescopic bracket 5 are different, and thus the rotation centers of the opening and closing operations are different.

In addition, other technical features of the present embodiment, such as the second spring 11 between the telescopic bracket 5 and the bracket assembly 1, and the adoption of the electric push rod as the telescopic device 3, etc., can be completely inherited from the first embodiment, and are not described herein again.

EXAMPLE III

The present embodiment is a multi-sunshade 2 linkage structure provided on the basis of the first and second embodiments.

The main motor drives the main shaft 13, and then drives the transmission modes of all the driving modules, so that the use of the motor is reduced, the size of equipment is reduced, and the cost of the equipment is saved. The transmission between the main shaft 13 and the telescopic device 3 is realized through a gear set or a similar transmission structure.

The specific shape of the plurality of sun visor panels 2 is not limited herein. The shapes of the plurality of sun visors 2 are not necessarily all the same. The plurality of sun visors 2 can be mutually matched to form a closed shape to realize the closing. In this arrangement, the plurality of visors 2 also divide the field of view into a plurality of panel configurations. As shown in fig. 8, which is a reference division structure.

Preferably, transmission between the telescopic device 3 and the main shaft 13 is controlled by an electromagnetic clutch 14. The opening and closing operations of all the sun visors 2 can be controlled to a certain degree by controlling each electromagnetic clutch 14 through a corresponding control system. Especially, when the field of view is divided by a plurality of sunshade panels 2, the opening and closing of different areas of the whole field of view can be controlled by controlling the electromagnetic clutch 14.

The utility model provides a pair of mechanical solar protection devices has two kinds of operating condition: the sun shield 2 extends outwards to leave a gap for ventilation; and further opens the sunshade 2 to transmit light. And the light transmission amplitude can be adjusted according to the opening amplitude of the sun shield 2, meanwhile, the effective transmission control can be carried out through the single telescopic device 3, and the structure is simple and reasonable. All the driving modules are completely integrated at the top or the bottom, and the view field in the middle of the sunshade plate 2 is completely free from the obstruction of a transmission structure, so that the view field is better. Can constitute closed structure by 2 concatenations of polylith sunshading board, realize dividing into polylith sunshading board 2 with the field of vision district to the switching printing opacity of the specific position in field of vision district is ventilative in the independent switching through sunshading board 2. The plurality of sun visors 2 can be controlled independently through the electromagnetic clutch 14, and can be driven independently by one motor, so that the driving structure is simplified.
