Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and particularly relates to a window sunshade device and a door panel. Background Art

[0002] Currently, for some vehicle models, a window sunshade device is provided on the vehicle door panel. The window sunshade device includes a sunshade curtain and a lifting mechanism. The sunshade curtain is wound on the inner side of the vehicle door panel. Driven by the lifting mechanism, the lifting mechanism drives the sunshade curtain to extend from the top of the vehicle door panel, thereby achieving sunshade. When sunshade is not required, the lifting mechanism drives the sunshade curtain to retract to the inner side of the vehicle door panel.

[0003] Combined Figure 7 As shown, it is a schematic top view of an existing window sunshade device, including a cover seat 14 and a moving block 20. The cover seat 14 is provided with a vertical opening groove. The cover seat 14 is provided with a cover body 9. The cover body 9 is driven by a flipping motor 19 to flip the cover body 9. The sunshade curtain 15 is wound on a winding shaft to form a curtain roll 12. A moving block 20 is provided below the cover seat 14. The moving block 20 is connected to the end of the sunshade curtain 15. When the sunshade curtain 15 needs to be raised, the flipping motor 19 drives the cover body 9 to rotate, the opening groove is exposed, and then the moving block 20 moves upward. The moving block 20 pulls the sunshade curtain 15 upward. When the sunshade curtain 15 is retracted, the moving block 20 moves below the cover seat 14, and then the flipping motor 19 drives the cover body 9 to rotate. The cover body 9 covers the opening groove on the cover seat 14 again to prevent the opening groove from being exposed. Therefore, the opening and closing of the opening groove in the prior art still need to be driven by the flipping motor 19. The flipping motor 19 itself occupies a certain cost. If the flipping motor 19 can be omitted, a certain cost can be saved and the vehicle sales profit can be increased.

[0004] Again, Chinese Patent Publication No. CN114228449B discloses a lifting drive device and a gland mechanism. The solution in this existing patent realizes the lifting drive of the sunshade curtain and the sunshade of the vehicle window. However, in this existing patent, the cover body at the opening groove on the vehicle door panel is controlled to open and close by a gland mechanism with a complex structure (the gland mechanism includes a bracket assembly, a fixed seat, and other structures). Since the gland mechanism is relatively complex and involves many components, this undoubtedly increases the production cost of the vehicle, reduces the profit of the manufacturer, or increases the selling price of the vehicle, and the purchase tendency of consumers will decrease.

[0005] Therefore, using fewer components to drive the opening and closing of the cover body is the key to reducing production costs, increasing sales volume, and increasing profits. Utility Model Content

[0006] The present utility model aims to provide a window sunshade device and a door panel, so as to drive the opening and closing of the cover body with a simpler structure.

[0007] To achieve the above object, the present utility model adopts the following technical solution: A window sunshade device includes a sunshade curtain, a winding shaft for winding the sunshade curtain, a cover body, a cover seat and a lifting mechanism; A strip-shaped opening groove is provided on the cover seat, the cover body covers the opening groove, the lifting mechanism is located below the cover body, the lifting mechanism includes a lead screw, a moving member and a motor for driving the lead screw to rotate, the moving member is threadedly connected to the lead screw, and the moving member is driven to move vertically by the rotation of the lead screw; One end of the sunshade curtain is fixedly connected to the bottom of the cover body; A driving rod is fixedly connected to the moving member, and the top end of the driving rod is fixedly connected to the bottom of the cover body.

[0008] The principle and advantages of this solution are as follows: In this application, the winding shaft is used to wind the sunshade curtain, the cover body is used to cover the opening groove, and the opening groove is used to allow the sunshade curtain to pass through. The lifting mechanism is used to drive the cover body and the sunshade curtain to move. In this application, the top end of the driving rod is fixedly connected to the bottom of the cover body, and the cover body is also connected to one end of the sunshade curtain. In this way, when the motor drives the lead screw to rotate, the lead screw drives the moving member to move, the moving member drives the driving rod to move, the driving rod drives the cover body to move, and the cover body then drives the sunshade curtain to move. When the moving member moves upward, the driving rod drives the cover body to move upward, the cover body moves away from the opening groove, the opening groove opens, and at the same time the cover body pulls the sunshade curtain upward, the sunshade curtain is gradually released from the winding shaft, and the sunshade curtain comes out from the opening groove, thus realizing the shielding of the window, and having the functions of sunshading and light shielding. When the moving member moves downward, the driving rod drives the cover body to move downward, and at the same time the winding shaft winds the sunshade curtain until the cover body covers the opening groove.

[0009] Therefore, the opening and closing of the cover body in this solution do not need to be realized by means of a complex component structure (such as the flipping motor and the pressing cover mechanism in the background art). When the driving rod is vertical, it simultaneously drives the cover body to move upward to open the opening groove or drives the cover body to move downward to cover the opening groove. The structure is simple and convenient, realizing the opening and closing of the cover body with fewer components, which is beneficial to reducing production costs and increasing sales profits. At the same time, the cover body in this application also has the function of driving the sunshade curtain to move, and there is no need to separately set a moving block structure. The structure is simple and convenient, which is beneficial to reducing components and production costs.

[0010] Preferably, as an improvement, a chamfer is provided at the bottom edge of the cover body.

[0011] Thus, the setting of the chamfer makes it easier for the bottom of the cover body to enter the groove when the cover body covers the opening groove downward.

[0012] Preferably, as an improvement, the cover body includes an insertion part and an edge part located at the top of the insertion part. The edge part protrudes from the side of the insertion part, and the chamfer is located on the bottom edge of the insertion part.

[0013] Thus, the insertion part is used to be inserted into the opening groove, and the edge part is used to block the gap between the inner wall of the opening groove and the insertion part.

[0014] Preferably, as an improvement, a cover body groove for accommodating the cover body is further provided on the top of the cover base. The cover body groove communicates with the opening groove, and the opening groove is located at the bottom of the cover body groove; the sunshade passes through the opening groove and is fixedly connected to the cover body.

[0015] Thus, the cover body groove is used to accommodate the cover body at the opening groove. In this way, when the cover body is located at the opening groove, the cover body does not protrude on the cover base, making the surface of the cover base relatively smooth.

[0016] Preferably, as an improvement, the number of driving rods is two. Two rod holes are provided at the bottom of the cover body groove. The two rod holes are respectively located outside the two ends of the opening groove. The driving rods are slidably located in the rod holes; the sunshade is located between the two driving rods, and blocking members are fixedly connected to the opposite inner walls of the opening groove on both sides, and the sunshade passes through between the two blocking members.

[0017] Thus, the blocking members in this solution are used to block the opening groove. In this way, when the cover body moves upward and is not covering the opening groove, there are blocking members at the opening groove to block the lower part of the opening groove, playing a role in closing the opening groove, so as to avoid external dust, sundries or dirt from falling into the inner part of the car door panel through the opening groove. At the same time, the blocking members block the opening groove, and the user cannot directly see the structures of some components inside the car door panel through the opening groove, and the blocking members play a role in decoration and beauty.

[0018] In this solution, the sunshade passes through between the two blocking members, so that the blocking members do not affect the vertical movement of the sunshade.

[0019] In addition, the two rod holes in this solution are respectively located outside the two ends of the opening groove. The reason for such a design is that in this way, the driving rods will not pass through the opening groove, the driving rods will not affect the setting of the blocking members, the blocking members will not affect the movement of the driving rods, and the blocking members and the driving rods will not interfere with each other. At the same time, the distance between the two driving rods is relatively large, and the two driving rods can be located at both ends of the cover body to support both ends of the cover body, making the driving rods drive the cover body to move more stably.

[0020] Preferably, as an improvement, the blocking member is made of rubber, silica gel or plastic.

[0021] Preferably, as an improvement, a reducer is connected to the motor, and the reducer is connected to the lead screw.

[0022] Thus, through the speed reducer, the speed of the motor is reduced, enabling the lead screw to rotate at a lower and stable speed.

[0023] This application also discloses an automobile door panel, including a door panel body and any one of the above window sunshade devices. An upper support plate and a lower support plate are fixedly connected to the inner side of the door panel body. The lower support plate is located below the upper support plate. A driving seat is installed on the lower support plate, and the motor is located on the driving seat. An axle bracket is fixedly provided on the upper support plate, and the winding shaft is rotatably connected to the axle bracket.

[0024] By arranging the window sunshade device on the door panel body, the function of sunshading for the automobile door panel is realized. The axle bracket on the upper support plate of the door panel body is used to support the winding shaft. The driving seat is installed on the lower support plate, and the driving seat is used to support the motor.

[0025] Preferably, as an improvement, a connecting rod is connected between the upper support plate and the lower support plate, and the driving rod is slidably connected to the upper support plate.

[0026] Thus, the connecting rod connects the upper support plate and the lower support plate together, thereby improving the connection stability between the upper support plate and the lower support plate.

[0027] Preferably, as an improvement, the top end of the lead screw is rotatably connected to the upper support plate.

[0028] Thus, the top end of the lead screw is rotatably connected to the upper support plate, and the upper support plate realizes the support and fixation of the top end of the lead screw, and the lead screw rotates relatively stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is a further detailed description through specific implementation manners:

[0037] The reference numerals in the accompanying drawings of the specification include: door panel body 1, lower support plate 2, drive seat 3, speed reducer 4, motor 5, moving member 6, drive rod 7, lead screw 8, cover body 9, edge portion 91, insertion portion 92, chamfer 93, upper support plate 10, shaft bracket 11, curtain roll 12, connecting rod 13, cover seat 14, sunshade curtain 15, shielding member 16, rod hole 17, cover body groove 18, flipping motor 19, moving block 20.

[0038] Embodiment 1

[0039] Basically as shown in the attached Figures 1-4 As shown: This embodiment discloses an automobile door panel (the automobile door panel is a structure for being installed on the inner side of an automobile metal door), including a door panel body 1 and a window sunshade device. The inner side portion (the side facing the metal door panel) of the door panel body 1 in this embodiment is fixedly connected (the fixing method can be fixing by screws or integral molding) with an upper support plate 10 and a lower support plate 2, and the lower support plate 2 is located below the upper support plate 10. Two connecting rods 13 are connected between the upper support plate 10 and the lower support plate 2. Through the connection of the connecting rods 13, the connection stability between the upper support plate 10 and the lower support plate 2 is improved.

[0040] This embodiment discloses a window sunshade device, including a sunshade curtain 15, a winding shaft for winding the sunshade curtain 15, a cover body 9, a cover seat 14 and a lifting mechanism.

[0041] The cover base 14 is integrally formed on the top of the door panel body 1. A strip-shaped opening groove (the length of the opening groove is not less than the transverse width of the sunshade 15) is provided on the cover base 14. The opening groove is used for the sunshade 15 to pass through, and the cover body 9 covers the opening groove. The lifting mechanism is located inside the door panel body 1 and below the cover body 9. The lifting mechanism in this embodiment includes a lead screw 8, a moving member 6, and a motor 5 for driving the lead screw 8 to rotate. The lead screw 8 in this embodiment is vertically arranged. The top end of the lead screw 8 is rotatably connected to the upper support plate 10 through a bearing. The lead screw 8 vertically passes through the lower support plate 2, and the lead screw 8 is rotatably connected to the lower support plate 2. Specifically, the rotational connection method can also be achieved through a bearing. A driving seat 3 is installed at the bottom of the lower support plate 2, and the installation method can be fixed by screws. The motor 5 and the reducer 4 are installed (for example, fixed by screws) on the driving seat 3. The output shaft of the motor 5 and the input shaft of the reducer 4 are coaxially connected (for example, connected by a coupling). The output shaft of the reducer 4 and the bottom end of the lead screw 8 are coaxially connected (for example, connected by a coupling). The reducer 4 in this embodiment functions to reduce the rotational speed of the motor 5 (the deceleration function is achieved by the meshing between the transmission gears inside the reducer 4. The deceleration principle of the reducer is well-known and will not be elaborated here), so that the rotational speed of the lead screw 8 is relatively low and stable. At the same time Figure 2 the reducer 4 in this embodiment also plays a role in changing the rotational direction (the change in the rotational direction is achieved by the bevel gears meshing with each other inside the reducer 4. The commutation function of the bevel gears is well-known and will not be elaborated here), so that the horizontal rotation of the motor 5 can be changed into the vertical rotation of the lead screw 8.

[0042] The moving member 6 in this embodiment is a moving plate. A vertical threaded hole is provided in the middle of the moving member 6. The lead screw 8 passes through the threaded hole of the moving member 6 and is threadedly connected to the moving member 6. Two driving rods 7 are respectively fixed (for example, fixed by screws or integrally formed) at both ends of the moving member 6. The upper support plate 10 is provided with holes for the driving rods 7 to pass through. In this way, the driving rods 7 pass through the upper support plate 10, and the top ends of the driving rods 7 are fixedly connected to the bottom of the cover body 9 (for example, fixed by screws or ultrasonic welding).

[0043] Thus, in this embodiment, it is realized that when the motor 5 rotates, the motor 5 drives the lead screw 8 to rotate through the reducer 4, the lead screw 8 drives the moving member 6 to move vertically, and the moving member 6 drives the cover body 9 to move up and down through the driving rods 7.

[0044] Two shaft frames 11 are fixedly connected (fixed by screws or ultrasonic welding) on ​​the upper support plate 10 in this embodiment, and the two ends of the winding shaft are rotatably connected to the shaft frames 11 respectively. The specific rotation method can be achieved by means of bearings or by the matching of shafts and holes. One end of the sunshade 15 in this embodiment is fixedly connected (fixed by bonding) to the circumferential surface of the winding shaft, and the winding and releasing of the sunshade 15 is achieved by the rotation of the winding shaft. After the sunshade is wound up, a curtain roll 12 is formed. A torsion spring (not shown in the figure) is connected between the winding shaft and the shaft frame 11. By setting the torsion spring, the winding shaft can have the force to roll up the sunshade 15.

[0045] One end of the sunshade 15 away from the winding shaft is fixedly connected (fixed in a manner such as bonding or fixing with screws) to the bottom of the cover body 9 .

[0046] Therefore, initially, the cover body 9 covers the opening groove of the cover seat 14, the opening groove is in a closed state, and the winding shaft is in a winding state for the sunshade curtain 15 under the elastic force of the torsion spring, and the sunshade curtain 15 is wound on the winding shaft to form a curtain roll 12.

[0047] When sunshade is needed, start the motor 5, and the motor 5 drives the screw 8 to rotate through the reducer 4, the screw 8 drives the movable part 6 to move upward, the movable part 6 drives the driving rod 7 to move upward, the driving rod 7 drives the cover body 9 to move upward, the opening groove of the cover seat 14 is opened, and at the same time the cover body 9 pulls the sunshade 15 upward, the sunshade 15 overcomes the elastic force of the torsion spring on the winding shaft and pulls the winding shaft, the winding shaft releases the sunshade 15, the sunshade 15 is pulled out from the winding shaft, and the sunshade 15 moves upward with the cover body 9, thereby realizing the rising of the sunshade 15, and the sunshade 15 blocks the windows on the door panel.

[0048] When the sunshade 15 is not needed, the control motor 5 rotates in the opposite direction, at which time the lead screw 8 rotates in the opposite direction, the movable member 6 moves downward, the driving rod 7 drives the cover body 9 to move downward, the top of the sunshade 15 moves downward, and the winding shaft automatically rotates under the elastic force of the torsion spring, thereby winding up the sunshade 15, thereby realizing the downward retraction of the sunshade 15 until the cover body 9 covers the opening groove.

[0049] Therefore, the opening and closing of the cover body 9 in this embodiment does not require the help of a complex component structure, and does not require the help of a flip motor 19. The structure is simple and convenient, and the opening and closing of the cover body 9 can be driven by fewer components, which is beneficial to reducing production costs and increasing sales profits.

[0050] The cover body 9 in this embodiment can be inserted into the opening slot. At this time, the cover body 6 is block-shaped. Figure 3As shown, when the method of inserting into the opening groove is selected, in other embodiments, the bottom edge of the cover body 9 is provided with a chamfer. The setting of the chamfer facilitates the insertion of the cover body 9 into the opening groove when the cover body 9 is covered on the opening groove.

[0051] In addition, in other embodiments, referring to Figure 6 As shown, a cover body groove 18 for accommodating the cover body 9 may be provided on the top of the cover base 14. The cover body groove 18 communicates with the opening groove, and the opening groove is located at the bottom of the cover body groove 18. In this way, when the cover body 9 is covered on the opening groove, the cover body 9 does not need to be inserted into the opening groove, and the cover body 9 is directly covered in the cover body groove 18, which can also achieve the sealing of the opening groove. At this time, the cover body 9 is relatively thin and plate-shaped. When the cover body 9 is covered on the cover body groove 18, the surface of the cover body 9 is flush with the surface of the cover base 14, and the cover body 9 does not protrude from the surface of the cover base 14.

[0052] Of course, when the cover body groove 18 is provided on the top of the cover base 14, in other embodiments, the cover body 9 further includes an insertion portion 92 and an edge portion 91 located at the top of the insertion portion 92. The edge portion 91 and the insertion portion 92 are integrally formed, the edge portion 91 protrudes from the insertion portion 92, a chamfer 93 is located on the bottom edge of the insertion portion 92, and the end of the sunshade 15 is fixedly located on the bottom of the insertion portion 92. In this way, when the cover body 9 is covered on the opening groove, the insertion portion 92 is inserted into the opening groove, the top and the edge portion 91 of the insertion portion 92 are located in the cover body groove 18, the surface of the cover body 9 is flush with the surface of the cover base 14, and the cover body 9 does not protrude from the surface of the cover base 14.

[0053] In the above embodiments, when the sunshade rises, the driving rod 7 passes through the opening groove.

[0054] Embodiment 2

[0055] Combined with Figure 5 and Figure 6 As shown, in this embodiment, the cover base 14 is provided with a cover body groove 18 and an opening groove. The opening groove is located at the bottom of the cover body groove 18, and the length of the opening groove is less than the length of the cover body groove 18. Figure 5The cover 9 is used to cover in the cover groove 18. The cover 9 is plate-shaped, and the edge of the cover 9 is provided with a chamfer 93, so as to facilitate the cover 9 to cover in the cover groove 18. The bottom of the cover 9 is fixedly connected (such as bonded) to the end of the sunshade 15. There are two rod holes 17 on the cover base 14. The two rod holes 17 are respectively located outside both ends of the opening groove, and both of the two rod holes 17 are located at the bottom of the cover groove 18. The driving rod 7 passes through the rod holes 17 and slides in the rod holes 17. In this embodiment, the sunshade 15 is located between the two driving rods 7. The top view shape of the opening groove is rectangular, and the shape of the cover groove 18 is runway-shaped. Fixedly connected to the inner walls on both sides of the opening groove are shielding members 16. The sunshade 15 passes through the gap between the two shielding members 16. The shielding member 16 is sheet-shaped, specifically made of rubber, silica gel or plastic. Selecting this kind of material is relatively soft. The specific fixing method of the shielding member 16 and the opening groove can be: strip-shaped grooves are provided on the inner walls on both sides of the opening groove, and the end of the shielding member 16 away from the sunshade 15 is inserted into the strip-shaped grooves and adhered in the strip-shaped grooves.

[0056] Thus, in this embodiment, the shielding member 16 is used to shield the opening groove. When the cover 9 moves upward, the cover 9 drives the sunshade 15 to move in the gap between the two shielding members 16. There is the shielding member 16 at the opening groove to shield the lower part of the opening groove, so as to avoid external dust, sundries or dirt from falling into the inner part of the car door panel through the opening groove. At the same time, the shielding member 16 shields the opening groove, and the user cannot directly see the structure of some components inside the car door panel through the opening groove. The shielding member 16 plays a role in decoration and beautification.

[0057] The above are only embodiments of the present utility model.
