Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1 to 3, an embodiment of the present invention provides a mechanical sun-shading device, which includes a bracket assembly 1, a sun-shading board 2, and a driving module; the driving module comprises a telescopic device 3, a telescopic rail 4, a telescopic bracket 5, a sliding member 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 pushing mode; the telescopic rail 4 is fixedly arranged on the bracket assembly 1 along the jacking direction of the telescopic device 3, and the telescopic bracket 5 is in sliding connection with the telescopic rail 4; the telescopic bracket 5 is provided with a sliding rail 8 arranged along the telescopic direction of the telescopic device 3, the sliding member 6 is in sliding connection with the sliding rail 8, the sliding member 6 is connected with the movable end of the telescopic device 3, and a first spring 7 with elasticity opposite to the propping and stretching direction of the telescopic device 3 is arranged between the sliding member 6 and the telescopic bracket 5; the back side of the sun visor 2 is hinged with the front end of the telescopic bracket 5, and the back side of the sun visor 2 is in transmission connection with the sliding member 6 through an opening and closing mechanism.
The working principle of the invention is as follows:
the telescopic device 3 pushes outwards, the sliding member 6 is driven to push outwards, and because the sliding member 6 and the telescopic bracket 5 have the resistance of the first spring 7, the sliding member 6 drives the whole telescopic bracket 5 to slide outwards along the telescopic rail 4 at the moment, the sun shield 2 also slides outwards along with the whole telescopic bracket 5, and a gap is formed between the sun shield and the bracket assembly 1 for ventilation. If the user has only a ventilation need, the telescopic device 3 can stop pushing up until this point.
If it is desired to open the sun visor 2 still further, the telescopic device 3 can be controlled to continue pushing forward. At this time, the telescopic bracket 5 is already moved to the forefront limit of the telescopic rail 4 and cannot continue to move forward, the sliding member 6 overcomes the resistance of the first spring 7 and continues to move forward, and relative sliding is generated between the sliding member and the telescopic bracket 5, and the opening and closing mechanism is driven to open the sun shield 2. The opening amplitude corresponds to the pushing amplitude of the telescopic device 3, so that this opening amplitude can also be controlled at will.
If the sun visor 2 is to be closed, the telescopic device 3 is retracted backward, and the closing motion is the reverse motion of the above motion, which is not described herein.
There are two preferred solutions for the opening and closing mechanism. In this embodiment, as a first preferred solution, the opening and closing mechanism includes a lever 9 and a first link 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 member 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 forwards relative to the telescopic bracket 5, the deflector rod 9 swings around the hinging point in the middle, and pulls the first connecting rod 10 to pull backwards, so that the sun shield 2 is driven to be opened 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 chute extending along the length direction of the shift lever, and the sliding member 6 is connected with the chute. So that the end of the sliding member 6 and the deflector rod 9 will not die when the telescopic device 3 pushes the sliding member 6 to slide forward.
In order to further provide a more defined action to the drive module, a second spring 11 having the same elastic force as the extension direction of the telescopic device 3 is preferably provided between the telescopic bracket 5 and the bracket assembly 1. During the outward pushing of the telescopic device 3, the second spring 11 will provide assistance to push the whole telescopic bracket 5 to slide forwards. This avoids that the sliding motion of the telescopic bracket 5 is hindered because the telescopic rail 4 is not smooth to slide, and the working beat of the whole driving module is affected.
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 capability of outsourcing. Of course, the telescopic device 3 can also adopt other structures such as a linear motor, a belt transmission or a chain transmission, but the electric push rod is certainly the scheme which can save the volume and simplify the structure from the aspect of simplifying the device.
In addition, although the drawings show the structure that the driving module is arranged on the top, the driving module can be arranged on the bottom in a reverse way. The sun visor 2 is thus not limited to being opened up or down.
Example two
The only difference between the present 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 link 12; the back side 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 middle of the back side of the sun visor 2, and the rear end of the second link 12 is hinged to the sliding member 6.
The second connecting rod 12 is directly adopted to directly transmit the pushing action force of the telescopic device 3, and the force application direction is the same as the pushing direction, so that the sun shield 2 is "supported". In the first embodiment and the second embodiment, the hinge position of the back side of the sun visor 2 and the telescopic bracket 5 is different, and thus the rotation center of the opening and closing operation is 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 use of an electric push rod as the telescopic device 3, may be completely inherited from the first embodiment, and will not be described herein.
Example III
The present embodiment provides a multi-sun visor 2 linkage structure based on the first and second embodiments.
Referring to fig. 7, more specifically, preferably, the sun visor 2 is provided with a plurality of blocks, and each block is in transmission connection with a corresponding driving module; and the bracket assembly 1 is also provided with a main shaft 13 and a main motor, the main motor is in transmission connection with the main shaft 13, and each telescopic device 3 is in transmission connection with the main shaft 13.
The main motor drives the main shaft 13, and then drives the transmission mode of all driving modules, thereby being beneficial to reducing the use of the motor, reducing the volume of the equipment and saving the cost of the equipment. The main shaft 13 and the telescopic device 3 are driven by a gear set or a similar driving structure.
The specific shape of the plurality of sun visors 2 is not limited herein. The shape of the plurality of sun visors 2 is not necessarily identical. The plurality of sun visors 2 can be mutually matched to form a closed shape to realize the closure. In this case, the plurality of sun visors 2 also divide the field of view into a plurality of plate structures. As shown in fig. 8, a reference split structure is provided.
Preferably, the 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 extent by controlling each electromagnetic clutch 14 by a corresponding control system. Particularly, when the field of view is divided by the plurality of sun visors 2, the electromagnetic clutch 14 is controlled to realize the opening and closing control of different areas of the whole field of view.
The invention provides a mechanical sun-shading device, which has two working states: the sun shield 2 extends outwards to leave gaps for ventilation; and a state in which the sun visor 2 is further opened to transmit light. And the light transmission amplitude can be adjusted according to the opening amplitude of the sun shield 2, and meanwhile, the effective transmission control can be carried out through the single telescopic device 3, so that the structure is simple and reasonable. All driving modules are completely integrated at the top or the bottom, and the vision area in the middle of the sun visor 2 is completely free from the obstruction of a transmission structure, so that the vision is better. The multiple sun visors 2 can be spliced to form a closed structure, so that the visual field area is divided into the multiple sun visors 2, and the specific position of the visual field area is opened and closed, light-transmitting and ventilation are realized through independent opening and closing of the sun visors 2. The plurality of sun visors 2 can be independently controlled through the electromagnetic clutch 14, and can be independently driven by a motor, so that the driving structure is simplified.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
