Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in 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 a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1 to 3, an embodiment of the invention provides an electromechanical sunshade, which includes a bracket assembly 1, a sunshade 2, and a driving module; the driving module comprises a telescopic device 3, a swing arm 4 and a hinge 5; the rear ends of at least two parallel swing arms 4 are hinged with the bracket assembly 1, and the front ends of the swing arms 4 are hinged with hinge hinges 5 to form a parallelogram mechanism; the middle part of the back side of the sun shield 2 is hinged with the front end of the swing arm 4 through a hinge 5; the movable end of the telescopic device 3 is hinged with the end part of the back side of the sun shield 2, and the mounting end of the telescopic device 3 is connected with the bracket assembly 1; and a limiting part 6 is fixedly arranged on the bracket assembly 1, so that the swing arm 4 is contacted with the limiting part 6 for limiting when swinging outwards to the maximum amplitude.

The working principle of the invention is as follows:

the telescopic device 3 is contracted to drive the swing arm 4 to swing outwards. Because the hinge 5 and the swing rod form a parallelogram mechanism, the hinge 5 and the sun shield 2 connected with the hinge do not open and close until the swing arm 4 abuts against the limiting part 6 for limiting. At this time, a gap is formed between the sun visor 2 and the bracket assembly 1, which can be used for ventilation. If the user only needs ventilation, the telescopic device 3 can stop shrinking.

If the sun visor 2 is further opened, the telescopic device 3 can be controlled to be continuously contracted, and the sun visor 2 is driven to perform opening movement by virtue of the hinge 5. The opening amplitude corresponds to the contraction amplitude of the telescopic means 3, and this opening amplitude can therefore also be controlled at will.

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

There are three preferred embodiments of the invention for the telescopic device 3.

In this embodiment, as a first preferable scheme, the telescopic device 3 is an electric push rod, a movable end of the electric push rod is hinged to the back end of the sun visor 2, and a mounting end of the electric push rod is hinged to the bracket assembly 1.

The embodiment is the simplest scheme. The electric push rod hinged with the support assembly 1 can automatically swing to adapt to the movement in the telescopic process, and a driving motor is arranged in the electric push rod. However, the electric push rod that swings with extension and retraction is only suitable for independent operation of a single sun visor 2, and it is difficult to achieve linkage between a plurality of sun visors 2.

In order to further ensure the driving module to have more definite action, a spring 7 with an outward elastic direction is preferably arranged between the swing arm 4 and the bracket assembly 1. In the process of contracting the telescopic device 3, the spring 7 firstly provides assistance to push the swing rod to swing outwards. Therefore, the situation that the swinging motion is hindered due to unsmooth swinging of the swing rod and the working beat of the whole driving module is influenced is avoided. Meanwhile, when the electric push rod is used as the telescopic device 3, the telescopic direction can provide acting force, so that the push force can be provided when the sun shield 2 is closed, and the swing rod can be swung and closed against the elastic force of the spring 7.

Example two

The difference between this embodiment and the first embodiment is: a connecting rod 8 is added between the telescopic device 3 and the sun shield 2, so that the overall running track of the mechanism is improved.

Referring to fig. 4 to 7, specifically, the extension device 3 is an electric push rod, a connecting rod 8 is further connected between the electric push rod and the back end of the sun visor 2, and two ends of the connecting rod 8 are respectively hinged to the back end of the sun visor 2 and the movable end of the extension device 3; the mounting end of the telescopic device 3 is fixedly arranged on the bracket assembly 1.

In this embodiment, the telescopic device 3 is also an electric push rod, but it is not a swing structure, but is fixedly installed on the bracket assembly 1. The telescopic device 3 does not swing any more, so that the linkage among the plurality of driving modules of the plurality of sun visors 2 is favorably realized.

With reference to fig. 7, by virtue of the above advantages, preferably, the sun visor 2 is provided with a plurality of blocks, each block being in transmission connection with a corresponding driving module; and the support assembly 1 is also provided with a main shaft 9 and a main motor, the main motor is in transmission connection with the main shaft 9, and each telescopic device 3 is in transmission connection with the main shaft 9.

The main motor drives the main shaft 9, 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 9 and the telescopic device 3 is realized through a gear set or a similar transmission structure.

More preferably, the transmission between the telescopic device 3 and the main shaft 9 is controlled by an electromagnetic clutch 10.

Furthermore, the support assembly 1 is in a grid shape, and each grid is provided with a sun shield 2 and a driving module corresponding to the sun shield; the electric push rods and connecting rods 8 extend along the lattice framework of the support assembly 1.

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.

The opening and closing principle of this embodiment is the same as that of the embodiment, and the technical solution that the spring 7 is arranged between the swing arm 4 and the support assembly 1 to help determine the movement track can be inherited, which is not described herein again.

It should be noted that, since the extension device 3 can provide the force in the extending and retracting directions in the first and second embodiments, the driving module is not necessarily mounted at the top position of the sunshade plate 2, but can be mounted at the bottom position of the sunshade plate 2 upside down. The two are merely corresponding changes in action, and the principles are equivalent.

EXAMPLE III

The difference between this embodiment and the first embodiment is: the telescopic device 3 adopts a structure that a traction steel wire 12 pulls a slide block 11 to telescopically slide.

Referring to fig. 8 to 11, in particular, the telescopic device 3 includes a sliding block 11, a traction wire 12 and a winding wheel 13; the sliding block 11 is connected with the bracket assembly 1 in a sliding way and serves as a movable end of the telescopic device 3; a connecting rod 8 is arranged between the sliding block 11 and the sun shield 2, and two ends of the connecting rod 8 are respectively hinged with the top end of the back side of the sun shield 2 and the sliding block 11; the top end of the traction wire 12 is fixedly connected to the winding wheel 13 and wound on the surface of the winding wheel 13, and the bottom end of the traction wire 12 is fixedly connected to the sliding block 11, so that the winding traction wire 12 drives the sliding block 11 to slide when the winding wheel 13 rotates.

This construction is completely different from the first and second embodiments in that the traction wire 12 can only generate a contracting pulling force and not an extending pushing force. Therefore, the present embodiment cannot adopt the solution of providing the spring 7 between the swing arm 4 and the support assembly 1 to ensure the motion track.

Preferably, the limit portion 6 is provided with an electromagnetic device 14, and the swing arm 4 is fixedly provided with a suction portion matched with the electromagnetic device 14. When the swing arm 4 reaches the limit part 6 for limiting, the electromagnetic device 14 generates magnetic force to adsorb the swing arm 4; when the sun visor 2 is closed, the electromagnetic device 14 demagnetizes and releases the swing arm 4.

In contrast, the traction wire 12 is more beneficial to freely extend along the bracket assembly 1 and transmit, so the embodiment is the most beneficial technical scheme for linkage of multiple sun visors 2 and multiple driving modules.

In this embodiment, 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 support assembly 1 is also provided with a main shaft 9 and a main motor, the main motor is in transmission connection with the main shaft 9, and each winding wheel 13 is in transmission connection with the main shaft 9. Further preferably, transmission between the winding wheel 13 and the main shaft 9 is controlled by an electromagnetic clutch 10.

In detail, as shown in fig. 11, the support assembly 1 is in a grid shape, and each grid is provided with a sun visor 2 and a driving module corresponding to the sun visor; the slide block 11, the connecting rod 8 and the traction steel wire 12 extend along the grid framework of the bracket assembly 1, wherein a fixed pulley 15 is arranged at the intersection point of the framework, and the traction steel wire 12 is wound on the surface of the fixed pulley 15. The frame assembly 1 shown in fig. 11 is an open structure for showing the direction of the traction wire 12 and the fixed pulley 15, the driving module, etc., and the actual installation can be completely shielded and protected on the surface.

Different from the second embodiment, the direction of the traction wire 12 in the second embodiment is more free, and the guide is changed through the fixed pulley 15, so that the linkage is more convenient to realize, the limitation is less, and the shape and the division of the sun visor 2 are more free and changeable.

The electromechanical sunshade provided by the invention has the function that the sunshade plate 2 extends outwards to leave a gap for ventilation, and the sunshade plate 2 can be further opened for light transmission, and the light transmission amplitude can be adjusted according to the opening amplitude of the sunshade plate 2. And the driving module is small in size, simple in structure, small in size, convenient to hide, and especially capable of constructing the support assembly 1 into a latticed frame structure, and the driving module can be arranged along the frame in an extending mode and is small in obstruction to the visual field. The plurality of sunshading boards 2 can be spliced to form a closed structure, so that the vision area is divided into the plurality of sunshading boards 2, and the vision area is opened and closed at specific positions through independent opening and closing of the sunshading boards 2 to realize light transmission and ventilation. Meanwhile, the linkage scheme is adopted, the plurality of sun visors 2 can be controlled independently through the electromagnetic clutch 10, and can be driven independently by one motor, so that the driving structure is simplified.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
