Technical Field

[0001] This invention belongs to the field of automotive parts technology, and relates to an electric cargo cover and a vehicle. Background Technology

[0002] A cargo cover is a vehicle accessory installed in the trunk to protect privacy by concealing items inside when pulled out. Besides privacy, cargo covers also enhance vehicle safety during high-speed braking by preventing luggage from entering the passenger compartment due to inertia. Furthermore, cargo covers can also be used as storage shelves for items.

[0003] Currently, most vehicles are equipped with manually retractable cargo covers. With social development, electric cargo covers are also being used. Electric cargo covers can extend the curtain by being driven by a motor, but their structure is relatively complex, involving many parts, and requiring a large driving torque when extending, so there is room for improvement.

The output shaft of the motor is connected to a drive connector. The drive connector is located on the side of the first base where the first mounting port is located. The end of the drive screw is provided with a driven connector. The driven connector is provided with a circumferential locking hole. The drive connector is inserted into the circumferential locking hole and circumferentially locked with the driven connector so that the drive screw is connected to the motor.

[0011] Preferably, the curtain frame is provided with a winding torsion spring, the two ends of which are connected to the curtain frame and the roller blind tube respectively, and the winding torsion spring applies a torque to the roller blind tube to wind up the curtain fabric.

[0012] Preferably, there are two nut sliders and two drive connecting rods. Both nut sliders are threadedly connected to the drive screw. When the drive screw rotates, the sliding directions of the two nut sliders are opposite. The two drive connecting rods are respectively hinged to the two nut sliders.

[0013] Preferably, the drive screw has a first threaded section and a second threaded section, the first threaded section and the second threaded section having opposite thread directions, and the two nut sliders are respectively threadedly connected to the first threaded section and the second threaded section.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figures 1 to 10 As shown, an electric blind includes:

[0034] A curtain frame 100 is provided, and a roller shutter tube 110 is provided inside the curtain frame 100. A curtain fabric 120 is provided on the roller shutter tube 110.

[0035] The rigid board 200 is connected to the end of the curtain 120, and the distance between the rigid board 200 and the curtain frame 100 determines the unfolding range of the curtain 120.

[0036] The unfolding mechanism includes a motor 300, a drive frame 400, a drive screw 500, a nut slider 600, and a drive connecting rod 700. The drive frame 400 is fixedly connected to the curtain frame 100. The drive screw 500 is rotatably mounted on the drive frame 400. The motor 300 is connected to the drive screw 500. The nut slider 600 is slidably connected to the drive frame 400 and threadedly connected to the drive screw 500. One end of the drive connecting rod 700 is hinged to the nut slider 600 and the other end is hinged to the rigid plate 200.

[0037] The curtain frame 100 houses the roller shutter tube 110, which winds and stores the curtain fabric 120. The rigid plate 200 is a rigid plate connected to the free end of the curtain fabric 120. The rigid plate 200 provides a traction point for the curtain fabric 120, allowing it to extend when pushed out (i.e., away from the curtain frame 100). In the unfolding mechanism, the motor 300 provides the torque to unfold the curtain fabric 120. The shaft of the motor 300 is connected to the drive screw 500 and can drive the drive screw 500 to rotate. When the drive screw 500 rotates, the nut slider 600 moves linearly along the axial direction of the drive screw 500. One end of the drive link 700 is hinged to the nut slider 600, and the other end is hinged to the rigid plate 200. The drive link 700 converts the linear motion of the nut slider 600 into the translational motion of the rigid plate 200, thereby driving the curtain fabric 120 to extend.

[0038] From the perspective of the extension principle of the curtain 120, the nut slider 600, the drive connecting rod 700 and the rigid plate 200 constitute a variant structure of a crank slider. Since one end of the drive connecting rod 700 is hinged to the nut slider 600, when the nut slider 600 slides, one end of the drive connecting rod 700 slides together with the nut slider 600, while the other end of the drive connecting rod 700 pushes or pulls the rigid plate 200 to slide, thereby extending the curtain 120 or allowing the curtain 120 to roll up.

[0039] In the actual structure, when the curtain fabric 120 is in the rolled-up state, the distance between the rigid plate 200 and the curtain frame 100 is the smallest, the angle between the drive connecting rod 700 and the drive frame 400 is the smallest, and the nut slider 600 is close to the end position of the drive screw 500. Taking the actual extension process of the curtain fabric 120 as an example, the motor 300 starts, driving the drive screw 500 to rotate, the nut slider 600 slides towards the middle area of ​​the drive screw 500, the angle between the drive connecting rod 700 and the drive frame 400 gradually increases, and the drive connecting rod 700 pushes the rigid plate 200 away from the curtain frame 100, thereby extending the curtain fabric 120.

[0040] The motor 300 can drive the nut slider 600 to slide through the drive screw 500. When the nut slider 600 slides, it can drive the rigid plate 200 to move through the drive connecting rod 700, thereby extending the curtain 120. Its overall structure is simple and ingenious, requiring few parts, and only a small driving torque is needed to extend the curtain 120.

[0041] Based on the above implementation, the curtain frame 100 is provided with a winding torsion spring. The two ends of the winding torsion spring are respectively connected to the curtain frame 100 and the roller blind tube 110. The winding torsion spring applies a torque to the roller blind tube 110 to make it wind up the curtain fabric 120.

[0042] The main function of the unfolding mechanism is to drive the rigid plate 200 to slide, thereby moving the rigid plate 200 closer to or away from the curtain frame 100. Specifically, when the rigid plate 200 slides away from the curtain frame 100, it can pull the curtain fabric 120 to extend; while when the rigid plate 200 slides closer to the curtain frame 100, the curtain fabric 120 cannot be rolled back onto the roller shutter tube 110. Therefore, a winding torsion spring needs to be designed to drive the roller shutter tube 110 to roll up the curtain fabric 120.

[0043] When the curtain 120 is extended, the roller shutter tube 110 rotates, releasing the curtain 120. At the same time, the winding torsion spring is twisted and stores elastic potential energy. When it is necessary to wind up the curtain 120, the motor 300 rotates in the reverse direction, and the drive screw 500 reverses accordingly, causing the nut slider 600 to slide in the reverse direction. This, in turn, pulls the rigid plate 200 closer to the curtain frame 100 via the drive linkage 700. The winding torsion spring releases the stored elastic potential energy, causing the roller shutter tube 110 to reverse, thereby winding the curtain 120 back into the roller shutter tube 110.

[0044] like Figures 1 to 4 As shown, based on the above embodiment, there are two nut sliders 600 and two drive connecting rods 700. Both nut sliders 600 are threadedly connected to the drive screw 500. When the drive screw 500 rotates, the sliding directions of the two nut sliders 600 are opposite. The two drive connecting rods 700 are respectively hinged to the two nut sliders 600.

[0045] Preferably, the two drive links 700 are symmetrically arranged about the center line of the rigid plate 200.

[0046] The two drive links 700 form a symmetrical structure, so the movement of the two drive links 700 is completely synchronous and symmetrical. By pushing or pulling the rigid plate 200 synchronously through the two symmetrical drive links 700, the rigid plate 200 is subjected to uniform force, avoiding jamming or tilting that may be caused by unilateral drive, and making the unfolding and rewinding process of the curtain 120 more stable and reliable.

[0047] Based on the above embodiments, the drive screw 500 has a first threaded section 510 and a second threaded section 520, the thread directions of the first threaded section 510 and the second threaded section 520 are opposite, and the two nut sliders 600 are threadedly connected to the first threaded section 510 and the second threaded section 520 respectively.

[0048] The thread on the drive screw 500 is divided into two sections: one is a right-hand thread and the other is a left-hand thread. When the drive screw 500 rotates, the two nut sliders 600 will move in opposite directions simultaneously because the threads are in opposite directions.

[0049] like Figures 1 to 10As shown, based on the above embodiment, it also includes a mounting bracket, which includes a first base 800 and a second base 900, and the two ends of the curtain frame 100 are respectively connected to the first base 800 and the second base 900.

[0050] The first base 800 and the second base 900 are respectively installed on both sides of the vehicle's trunk to support the curtain frame 100. The curtain frame 100 is fixed between the first base 800 and the second base 900, while the rigid plate 200 can slide along the length of the first base 800 and the second base 900.

[0051] Based on the above embodiment, a slide bar 210 is provided on the side of the rigid plate 200 near the curtain 120. The curtain 120 is connected to the slide bar 210. The first base 800 and the second base 900 are respectively provided with a first slide groove 810 and a second slide groove 910. The two ends of the slide bar 210 are slidably connected to the first slide groove 810 and the second slide groove 910, respectively.

[0052] The two ends of the slide bar 210 are respectively embedded in the first slide groove 810 and the second slide groove 910. When the motor 300 drives the rigid plate 200 to slide, the slide bar 210 slides along the first slide groove 810 and the second slide groove 910, providing a linear guide for the movement of the rigid plate 200.

[0053] like Figures 1 to 10 As shown, based on the above embodiment, the inner side of the first base 800 is provided with a first mounting port 820, the inner side of the second base 900 is provided with a second mounting port 920, the two ends of the curtain frame 100 are respectively provided with the first mounting port 820 and the second mounting port 920, the second base 900 is provided with an insert port 930, the insert port 930 is connected to the second mounting port 920 and the second sliding groove 910; the second base 900 is hinged with a cover 950, the cover 950 has an open position and a closed position, when the cover 950 is in the open position it is separated from the insert port 930, when the cover 950 is in the closed position it seals the insert port 930.

[0054] The first mounting port 820 and the second mounting port 920 are designed as hole structures for inserting the two ends of the curtain frame 100. The insertion port 930 is designed as an upper opening structure of the second mounting port 920. The cover 950 is used to close or open the insertion port 930. The design of the insertion port 930 allows the operator to insert the end of the curtain frame 100 into the second mounting port 920 from above, while allowing the end of the slide bar 210 to enter the second slide groove 910. This simplifies the installation process of the curtain frame 100, reduces the installation difficulty, and the openable and closable cover 950 forms a reliable mechanical constraint, preventing the curtain frame 100 from coming out of the insertion port 930 and ensuring the stability of the installation.

[0055] Based on the above embodiment, the motor 300 is mounted on the first base 800, and the output shaft of the motor 300 is connected to a drive connector 310. The drive connector 310 is located on the side of the first base 800 where the first mounting port 820 is opened. The end of the drive screw 500 is provided with a driven connector 530. The driven connector 530 is provided with a circumferential locking hole 531. The drive connector 310 is inserted into the circumferential locking hole 531 and circumferentially locked with the driven connector 530.

[0056] The motor 300 is mounted on the outer side of the first base 800, and the output shaft of the motor 300 passes through the wall of the first base 800 and is connected to the drive connector 310. The motor 300 is circumferentially locked to the drive screw 500 through the drive connector 310 and the driven connector 530, thereby transmitting torque.

[0057] Preferably, the shapes of the circumferential locking hole 531 and the drive connector 310 are specially designed. The diameter of the circumferential locking hole 531 gradually decreases from the bottom of the hole to the opening, making the circumferential locking hole 531 form a conical gear hole structure. The shape of the drive connector 310 is complementary to the shape of the circumferential locking hole 531, and it is similar to a bevel gear structure. This design allows the drive connector 310 and the circumferential locking hole 531 to be connected without axial alignment. The curtain frame 100 (drive screw 500) can be installed in a relatively tilted initial posture. First, the end of the drive screw 500 with the driven connector 530 is abutted against the drive connector 310. As the curtain frame 100 (drive screw 500) is gradually flattened, the drive connector 310 is gradually inserted into the circumferential locking hole 531. In addition, it is very convenient to disassemble. Just lift the end of the curtain frame 100 (drive screw 500) corresponding to the second mounting port 920, and the drive connector 310 will gradually come out from the circumferential locking hole 531, which greatly reduces the difficulty of assembling and disassembling the curtain.

[0058] The assembly process of the blind is as follows: the motor 300 is fixed on the outside of the first base 800, and the output shaft of the motor 300 passes through the inside of the first base 800. The drive connector 310 is set on the output shaft of the motor 300 and is located inside the first base 800. First, the curtain frame 100 and the first base 800 are assembled. One end of the curtain frame 100 is inserted into the first mounting port 820. At this time, one end of the slide bar 210 is inserted into the first slide groove 810. The driven connector 530 of the drive screw 500 is precisely connected with the drive connector 310, and the drive connector 310 is inserted into the circumferential locking hole 531 of the driven connector 530 to lock the two circumferentially, thereby realizing the connection between the drive screw 500 and the motor 300. This design can greatly reduce the assembly difficulty of the drive screw 500 and the motor 300, realize quick-connect connection, and is also very convenient for subsequent disassembly.

[0059] Next, assemble the curtain frame 100 with the second base 900, ensuring the cover 950 is open so that there is no obstruction inside or above the insertion port 930. Then, insert the other end of the curtain frame 100 into the second mounting port 920 from top to bottom through the insertion port 930. At this time, the other end of the slide bar 210 enters the second sliding groove 910. Then close the cover 950, which seals the insertion port 930, thereby constraining the other end of the curtain frame 100 within the second mounting port 920, preventing it from exiting through the insertion port 930.

[0060] Based on the above embodiment, the cover 950 is provided with a locking block 960, which is slidably connected to the cover 950. The second base 900 is provided with a locking groove 940 on the wall corresponding to the mounting opening 930. When the cover 950 is in the closed position, the locking block 960 is inserted into the locking groove 940 to restrict the rotation of the cover 950. When the locking block 960 is separated from the locking groove 940, the cover 950 is allowed to rotate.

[0061] An elastic element is provided between the locking block 960 and the cover 950, and the elastic element applies a spring force to the locking block 960 to extend it. When the cover 950 is located in the mounting opening 930, the locking block 960 is engaged with the locking groove 940 under the action of the elastic element, thereby constraining the cover 950 within the mounting opening 930 to ensure that the curtain frame 100 cannot be dislodged. When it is necessary to disassemble the curtain frame 100, the locking block 960 is pushed to separate it from the locking groove 940, at which point the cover 950 can be opened, thereby allowing the curtain frame 100 to disengage from the second mounting opening 920.

[0062] like Figures 1 to 10 As shown, based on the above embodiments, a vehicle includes an electric cargo cover. A first base 800 and a second base 900 are respectively installed on both sides of the vehicle's trunk. The control button for the motor 300 can be located on either the first base 800 or the second base 900. By controlling the forward and reverse rotation of the motor 300, the curtain 120 can be driven to automatically extend or retract.

[0063] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0064] Furthermore, in this invention, descriptions involving "first," "second," "a," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0065] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction between two elements, unless otherwise explicitly limited.

[0066] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
