[0031] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0032] Please also read Figures 1 to 3, the electric sunshade for front windshield provided by the utility model is now described. The electric sunshade for front windshield comprises: a driving motor 1, a rotating bracket 2, two sets of winding and stretching connecting rod mechanisms 3 and a sunshade assembly; the rotating bracket 2 is mounted on the main shaft of the driving motor 1 and can rotate forward and reversely with the main shaft; the two sets of winding and stretching connecting rod mechanisms 3 are symmetrically connected to the rotating bracket 2 with the main shaft of the driving motor 1 as the symmetry axis, and are respectively located on the left and right sides of the driving motor 1; the two sets of winding and stretching connecting rod mechanisms 3 move in opposite directions or in opposite directions along the left and right sides while rotating with the driving motor 1; the sunshade 5 assembly is located below the driving motor 1, and the sunshade 5 assembly comprises a retractor, a sunshade 5 wound on the retractor, and a bottom rod 4 arranged at the free end of the sunshade 5; the bottom rod 4 is provided with a slide rail extending in the left and right directions, and the execution ends of the two sets of winding and stretching connecting rod mechanisms 3 are slidably connected to the slide rail of the bottom rod 4, driving the sunshade 5 to be rolled up or unfolded downward.

[0033] The electric sunshade for the front windshield provided by the utility model can drive the reeling and stretching connecting rod mechanism 3 to rotate and move in opposite directions at the same time by driving the forward and reverse rotation of the driving motor 1, thereby driving the sunshade 5 to be reeled upward onto the reel 6 or unfolded downward.

[0034] like Figure 6 As shown, during installation, the drive motor 1 is installed on the vehicle body frame above the front windshield 9; the winder 6 is also installed on the vehicle body frame above the front windshield 9 and hidden in the interior of the roof frame, and will not be exposed within the visible range of human eyes. Figure 6 In the figure, the left and right sides of the front windshield 9 are A-pillars 11, and the lower part is a dashboard 10.

[0035] The driving motor 1 can directly use a motor with forward and reverse drive. In this article, the forward rotation of the driving motor 1 is set to clockwise rotation, and the reverse rotation of the driving motor 1 is set to counterclockwise rotation. At the same time, the driving motor 1 can be used to directly drive the rotating bracket 2. For example, the rotating bracket 2 is directly installed on the main shaft of the driving motor 1. At this time, the main shaft of the driving motor 1 is consistent with the front and rear directions of the vehicle body, and the driving motor 1 is located at the center of the left and right directions of the front windshield 9; the main shaft of the driving motor 1 can also be connected to a reversing reducer. At this time, the main shaft of the driving motor 1 can be consistent with the left and right directions of the vehicle body, and the output shaft of the reducer is consistent with the front and rear directions of the vehicle body.

[0036] Compared with the prior art, this electrically driven winding and stretching connecting rod mechanism 3 has the following beneficial effects:

[0037] (1) The button for controlling the drive motor can be integrated on the dashboard in the cab. The driver can start the drive motor by touching the button, thereby driving the winding and expanding linkage mechanism to rotate forward and reverse, driving the sunshade to be rolled up or expanded. The electric operation is simple and convenient. (2) The winding and expanding linkage mechanism 3 can be hidden between the sunshade 5 and the front windshield 9. The rising and expanding of the sunshade 5 are driven by the winding and expanding linkage mechanism 3. In the process of rising and expanding the sunshade 5, the winding and expanding linkage mechanism 3 is always connected to the lower end of the sunshade 5, which supports the sunshade 5. , no hanging parts are required at the lower end of the sunshade 5, thus avoiding unsafe driving factors caused by the sunshade 5 blocking the line of sight; (3) since the winding and stretching connecting rod mechanism 3 supports the sunshade 5, and the winding and stretching connecting rod mechanism 3 is arranged on the left and right, it can provide good support for the sunshade 5 and improve the flatness of the sunshade 5. When the sunshade 5 is used as a screen for watching movies, the viewing effect inside the car can be improved; (4) after the sunshade 5 is unfolded, it will not be connected to the instrument panel 10, will not occupy the upper area of ​​the instrument panel 10, and will not affect the visibility of the front appearance of the interior of the car.

[0038] In some embodiments, Figures 1 to 3 As shown, the winding and stretching connecting rod mechanism 3 includes a pull rod 31, a transfer rod 33 and a support rod 32; the transfer rod 33 has a first transfer portion and a second transfer portion extending in different directions, and the intersection position of the first transfer portion and the second transfer portion is rotatably connected to the top plate 7, wherein both ends of the retractor are connected to the top plate 7; one end of the pull rod 31 is hinged to the rotating bracket 2, and the other end of the pull rod 31 is hinged to the first transfer portion of the transfer rod 33; one end of the support rod 32 is connected to the second transfer portion of the transfer rod 33, and the other end of the support rod 32 is slidably connected to the slide rail on the bottom rod 4 as an execution end.

[0039] The transfer rod 33 has transfer parts with different directions. The support rod 32 can change the movement direction after the transfer rod 33 moves, and the resulting movement direction is opposite to the movement direction of the pull rod 31 on the same side.

[0040] The winding and stretching connecting rod mechanism 3 provided in this embodiment has the following process for winding up the sunshade 5: when the driving motor 1 rotates clockwise, the main shaft of the driving motor 1 drives the rotating bracket 2 to rotate clockwise, and the pull rods 31 connected on the left and right sides rotate clockwise with the rotating bracket 2. Since the other end of the pull rod 31 is also limited by the transfer rod 33, the pull rod 31 on the right side moves to the right, and the pull rod 31 on the left side moves to the left in the opposite direction. At this time, the first transfer part on the right transfer rod 33 rotates clockwise and moves away from the rotating bracket 2 to the right at the same time, driving the second transfer part to move closer to the rotating bracket 2. The first adapter part located on the left adapter rod 33 is pushed to the left by the pull rod 31 and rotates counterclockwise, and at the same time moves to the left away from the rotating bracket 2, driving the second adapter part to move in the opposite direction close to the rotating bracket 2; at this time, the right support rod 32 rotates clockwise and approaches the rotating bracket 2 upward, and the angle between the support rod 32 and the pull rod 31 gradually decreases, thereby driving the sunshade 5 to move upward, and the left support rod 32 rotates counterclockwise and approaches the rotating bracket 2 upward, driving the sunshade 5 to move upward, and the sunshade 5 is rolled up to the top of the front windshield 9 under the action of the retractor.

[0041] The unfolding process of the sunshade 5 is as follows: the driving motor 1 rotates counterclockwise, the rotating bracket 2 rotates counterclockwise, the right pull rod 31 rotates counterclockwise, driving the right adapter rod 33 to rotate counterclockwise, the first adapter part approaches the rotating bracket 2 to the left, and the second adapter part moves away from the rotating bracket 2 to the right, the angle between the right support rod 32 and the pull rod 31 gradually increases, the right support rod 32 gradually opens, and drives the sunshade 5 to unfold downward; at the same time, the left pull rod 31 rotates clockwise, the first adapter part approaches the rotating bracket 2 to the right, and the second adapter part moves away from the rotating bracket 2 to the left, the angle between the left support rod 32 and the pull rod 31 gradually increases, the left support rod 32 gradually opens, and drives the sunshade 5 to unfold downward. At this time, the distance between the two support rods 32 on the sunshade 5 slide rail gradually increases.

[0042] The angle between the support rod 32 and the pull rod 31 is related to the width of the sunshade 5 when it is unfolded downward. The larger the angle between the support rod 32 and the pull rod 31, the greater the width of the sunshade 5 when it is unfolded downward. When the support rod 32 is unfolded to be perpendicular to the pull rod 31, the width of the sunshade 5 when it is unfolded downward is the largest. When the support rod 32 is retracted to be parallel to the pull rod 31, the sunshade 5 is completely rolled up on the retractor 6.

[0043] Therefore, further, the line connecting the hinge point between the transfer rod 33 and the top plate 7 and the rotation center of the rotating bracket 2 is parallel to the left-right direction.

[0044] It should also be noted that due to the rotation of the adapter rod 33, the directions of the first adapter part and the second adapter part cannot be determined, but in a certain specific state, the directions of the two adapter parts can be basically determined. For example, when the sunshade curtain 5 is in a closed and rolled-up state, the second adapter part basically extends in the left-right direction, and the first adapter part basically extends upward.

[0045] The driving motor can be a stepper motor or servo motor that can rotate forward and reverse, or it can be a bidirectional electric push rod with a bidirectional telescopic rod. The reverse extension and retraction of the bidirectional electric push rod drives the pull rods on both sides to move in the same direction or in opposite directions, and then the sunshade is rolled up or unfolded through the action of the transfer rod and the support rod.

[0046] In the present application, one or two drive motors can be set. When one drive motor is set, the drive motor needs to rotate forward and reverse, and the drive motor is set in the middle position of the sunshade 5 in the left and right directions; when two drive motors are set, the two drive motors can be close to the left and right sides of the sunshade respectively, and the two drive motors can rotate in opposite directions at the same time to drive a group of winding and stretching connecting rod mechanisms 3 to move in the opposite direction respectively. At this time, the length of the pull rod 31 can be shortened; the two drive motors can also directly drive the transfer rod 32. For example, an eccentric cam can be set on the main shaft of the drive motor, and the transfer rod 33 can be hinged on the eccentric cam to realize the winding and unfolding of the sunshade 5.

[0047] In some embodiments, Figure 3 As shown, the other end of the support rod 32 is connected with a slider 34 that is slidably connected to the slide rail on the bottom rod 4. The support rod 32 is rotatably connected to the slider 34, and the support rod 32 also slides left and right along the slide rail at the bottom of the sunshade 5 while rotating with the transfer rod 33.

[0048] In some embodiments, Figure 7 As shown, the cross-sectional shape of the slide rail on the bottom bar 4 is a dovetail groove or a trapezoidal groove, and the slider 34 is confined in the slide rail. The slider 34 is confined in the slide rail, and the matching relationship formed by the slider 34 adapting to the cross-sectional shape of the slide rail can prevent the slider 34 from falling out of the slide rail. In addition, the cross-sectional shape referred to here is the shape presented by the cross section along the front-rear direction of the vehicle body.

[0049] In some embodiments, Figure 3 As shown, both ends of the slide rail are provided with anti-drop end caps 41, and the opposite side of the anti-drop end caps 41 is provided with buffer blocks 42. The buffer blocks 42 are provided to limit and buffer the movement of the support rod 32 to both ends of the slide rail, thereby preventing the support rod 32 from falling out of the slide rail when the drive motor 1 fails or the electrical components controlling the drive motor 1 fail, and also preventing the slider 34 from hard contact with the anti-drop end caps 41 to produce abnormal noise.

[0050] Optionally, the buffer block 42 is made of rubber or silicone.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, the connection position between the adapter rod 33 and the top plate 7 is located above the retractor to ensure that when the support rod 32 is retracted to be parallel or substantially parallel to the pull rod 31, the sunshade 5 is completely wound on the retractor 6, and from the perspective inside the vehicle, the retractor 6 has a cylindrical appearance.

[0052] In some embodiments, Figure 1 and Figure 2 As shown, the shape of the rotating bracket 2 is elliptical, and the pull rod 31 is hinged on the long axis of the rotating bracket 2. When the sunshade 5 is rolled up and closed, the long axis of the rotating bracket 2 is consistent with the left and right direction.

[0053] In some embodiments, Figure 4 As shown, a spline hole 21 is provided on the rotating bracket 2, and the rotating bracket 2 is key-connected with the main shaft of the driving motor 1. The key connection ensures that the rotating bracket 2 and the driving motor 1 rotate synchronously.

[0054] Furthermore, if Figure 2 and Figure 3 As shown, the rotating bracket 2 has a spline sleeve and clamping plates connected to both ends of the spline sleeve, and an escape space is formed between the two clamping plates. One end of the pull rod 31 has a flat head and extends into the escape space to prevent the end of the pull rod 31 from being exposed.

[0055] In some embodiments, Figures 1 to 3 As shown, the retractor includes a reel, a reel mounted on the reel, and a coil spring connected between the reel and the reel, and both ends of the reel are connected to the top plate 7 through a support 8. When the support rod 32 pushes the sunshade 5 to unfold downward, the reel overcomes the elastic force of the coil spring; when the support rod 32 drives the sunshade 5 to move upward, the coil spring elastically resets, drives the reel to rotate, and the sunshade 5 is wound on the reel.

[0056] It should be noted that the hinges mentioned in this article can all be connected by pins, and the hinges in each part will not be explained one by one.

[0057] In addition, it is mentioned in this article that the sunshade 5 can be used as a screen for watching movies. In this state, the lower end of the sunshade 5 can be manually pulled to increase the angle between the sunshade 5 and the front windshield 9, thereby maintaining the sunshade 5 in a certain vertical state and finding a comfortable viewing angle.

[0058] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0059] Based on the same inventive concept, an embodiment of the present application also provides a vehicle provided with the electric sunshade 5 for the front windshield 9 .

[0060] The vehicle provided by the embodiment of the utility model has the characteristics of simple operation, high driving safety, reliable viewing of the curtain inside the vehicle, and good visibility of the layout inside the vehicle due to the adoption of the electric sunshade curtain 5.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
