Description

Electric dual sunshade system, control method and new energy vehicles

[0001] This disclosure claims priority to Chinese Patent Application No. 202411830247.6, filed on December 12, 2024, entitled "An Electric Dual Sunshade System, Control Method and New Energy Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of automotive parts, and more particularly to an electric dual sunshade system, control method, and new energy vehicle. Background Technology

[0003] Compared to traditional gasoline-powered vehicles, most new energy vehicles adopt panoramic glass to provide a better riding experience. Users can enjoy the expansive view and spaciousness offered by panoramic glass. However, panoramic glass absorbs a significant amount of heat in summer, causing discomfort and discomfort, particularly for the head. The pursuit of minimal aerodynamic drag and styling in new energy vehicles results in a smaller Z-axis space between the driver's head and the panoramic glass, making existing sunshade structures unsuitable for installation within this limited space.

[0004] The related technology provides a double-opening sunshade curtain, including a panoramic sunshade curtain and a sunshade curtain. The sunshade curtain includes a front-opening sunshade curtain and a rear-opening sunshade curtain that cover the front and rear of the panoramic sunshade curtain respectively. A sunshade curtain drive assembly is installed in the middle of the panoramic sunshade curtain. In the above solution, the drive assemblies of the front-opening sunshade curtain and the rear-opening sunshade curtain are arranged separately at the front and rear ends, resulting in the entire sunshade curtain occupying a large space, and the distribution position of the drive assembly can easily affect the field of vision. Summary of the Invention

[0034] The beneficial effects of this invention are as follows:

[0035] This invention employs a dual sunshade structure with a front and rear sunshade, utilizing two rollers to reduce the roller diameter of a single sunshade. The roller structure is positioned at the junction of the two sunshades, thus not occupying headroom in the front or second row of the vehicle and not obstructing the driver's or passengers' view. The control motors for both the front and rear sunshades are mounted on the front crossbeam, simplifying the rear structure of the sunshades without affecting the view of front-seat occupants. Both the front and rear sunshades are equipped with a retraction mechanism. This mechanism, using a long support shaft, a short support shaft, a long spring, and a short spring in combination with a retractor, provides better retraction and support for the sunshades, preventing the fabric from saging when unfolded.

[0036] Because of the front and rear sunshade retractors, during the stretching process, the inner diameter of the retractor decreases until it is locked with the spring drum, which then drives the left helical end to rotate. Since the helical groove of the spring drum is connected to the short helical spring, it will drive the short helical spring to rotate. By setting the motor stall torque and the short helical spring rotation torque to achieve a balance, it can ensure that the sunshade is tightly sealed when closed, and can avoid the motor overtravel rotation causing the front sunshade retractor to be overstretched and irreversible.

The front sunshade motor 12 and the rear sunshade motor 13 have the same structure. The front sunshade motor 12 has a built-in stator and worm gear rotor. The worm gear rotor meshes with a worm gear, and the worm gear has a long shaft in the middle. The output end of the long shaft is connected to a transmission gear, which meshes with the left pull cord 14 (left pull cord 15 of the rear sunshade) and the right pull cord 16 (right pull cord 17 of the rear sunshade). The transmission gear rotates clockwise or counterclockwise following the rotation of the worm gear and the long shaft, driving the corresponding pull cord to move left and right in the guide groove.

[0088] In this embodiment, both the front sunshade motor 12 and the rear sunshade motor 13 are located on the front crossbeam 1. The front crossbeam 1 has a built-in left pull cord guide groove 18 for the front sunshade, a left pull cord guide groove 19 for the rear sunshade, a right pull cord guide groove 20 for the front sunshade, and a right pull cord guide groove 21 for the rear sunshade. That is, the drive devices for the front sunshade 4 and the rear sunshade 5 are all distributed on the front side of the entire system, making the overall structure more compact and the drive devices do not occupy too much space.

[0089] In this embodiment, the front sunshade motor 12 is located at the left end of the front crossbeam 1, and the rear sunshade motor 13 is located at the right end of the front crossbeam 1. The left pull cord 15 of the rear sunshade is located outside the left pull cord 14 of the front sunshade, and the length of the left pull cord 15 of the rear sunshade is greater than the length of the left pull cord 14 of the front sunshade. The right pull cord 17 of the rear sunshade is located outside the right pull cord 16 of the front sunshade, and the length of the right pull cord 17 of the rear sunshade is greater than the length of the right pull cord 16 of the front sunshade.

[0090] As shown in Figure 9, the front sunshade retraction mechanism includes a front sunshade retractor 33, a front sunshade roller sleeve 32, a front sunshade support roller 45, a front sunshade support long shaft 46, a front sunshade short helical spring 48, a front sunshade long helical spring 44, a front sunshade spring roller 43, and a front sunshade support short shaft 49. A front sunshade retractor 33 is connected to each end of the front sunshade roller sleeve 32. The left end of the front sunshade retractor 33 is connected to the left helical end 47 of the front sunshade, which is connected to the front sunshade support short shaft 49. The front sunshade short helical spring 48 is wound around the front sunshade support short shaft 49. The right-hand front sunshade retractor 33 is connected to the right-hand spiral end 42 of the front sunshade. The right-hand spiral end 42 is connected to the front sunshade support shaft 46. A front sunshade long spiral spring 44 is wound around the outside of the front sunshade support shaft 46, and a front sunshade spring cylinder 43 is sleeved on the outside of the front sunshade long spiral spring 44. The right end of the front sunshade support shaft 46 is connected to the right-hand spiral end 42 of the front sunshade, and the left end extends out of the front sunshade spring cylinder 43. A front sunshade support roller 45 is installed on the left end of the front sunshade support shaft 46. The front sunshade support roller 45 rolls in contact with the inner wall of the front sunshade roller sleeve 32. The front sunshade roller sleeve 32 is sleeved on the outside of the front sunshade spring cylinder 43 and the front sunshade support roller 45. The front sunshade support roller 45 also serves as the internal intermediate support and rotating roller of the front sunshade roller sleeve 32.

[0091] As shown in Figures 9, 16, and 17, the rear sunshade retraction mechanism includes a rear sunshade roller sleeve 30, a rear sunshade retractor 31, a rear sunshade support short shaft 41, a rear sunshade short helical spring 40, a rear sunshade support long shaft 38, a rear sunshade long helical spring 36, a rear sunshade spring cylinder 35, and a rear sunshade support roller 37. Both ends of the rear sunshade roller sleeve 30 are connected to a rear sunshade retractor 31. The rear sunshade retractor 31 located at one end of the rear sunshade roller sleeve 30 is connected to the rear sunshade support short shaft 41, and the rear sunshade support short shaft 41 is equipped with the rear sunshade short helical spring 40. The rear sunshade retractor 31, located at the other end of the rear sunshade roller sleeve 30, is connected to the rear sunshade support long shaft 38. The rear sunshade support long shaft 38 is equipped with a rear sunshade long spiral spring 36. A rear sunshade spring cylinder 35 is sleeved on the outside of the rear sunshade long spiral spring 36, and the rear sunshade roller sleeve 30 is sleeved on the outside of the rear sunshade short spiral spring 40 and the rear sunshade spring cylinder 35. A rear sunshade support roller 37 is mounted on the rear sunshade support long shaft 38, and the rear sunshade support roller 37 rolls in contact with the inner wall of the rear sunshade roller sleeve 30.

[0092] Since the left end of the front sunshade retractor 33 is connected to the front sunshade spring roller 43 and the right end is connected to the right spiral end 42 of the front sunshade, the front sunshade retractor 33 converts the spring stretching deformation into elastic potential energy during the closing of the front sunshade 4. During the opening of the front sunshade 4, the elastic potential energy is automatically released and drives the spring to retract, thereby driving the front sunshade roller sleeve 32 and the front sunshade 4 to retract and open.

[0093] As shown in Figures 10 and 11, the front sunshade retractor 33 and the rear sunshade retractor 31 in this embodiment have a similar spring-like structure.

[0094] Furthermore, as shown in Figure 19, the front sunshade spring roller 43 has a circular hole in the middle. The head of the front sunshade spring roller 43 is connected to the front sunshade retractor 33, and the connecting section with the head is provided with a spiral groove in the circumference. During the stretching process, the inner diameter of the front sunshade retractor 33 decreases until it is locked with the front sunshade spring roller 43, which drives the left spiral end 47 of the front sunshade to rotate. Because the spiral groove of the front sunshade spring roller 43 is connected to the front sunshade short spiral spring 48 as shown in Figure 21, it will drive the front sunshade short spiral spring 48 to rotate. By setting the stall torque of the front sunshade motor 12 and the rotation torque of the front sunshade short spiral spring 48 to achieve a balance, it can ensure that the sunshade is tightly sealed when closed, and can avoid the front sunshade motor 12 over-travel rotation causing the front sunshade retractor 33 to be overstretched and irreversible.

[0095] As shown in Figure 23, the short shaft 49 of the front sunshade support serves as the common support shaft for the front sunshade spring roller 43, the front sunshade short helical spring 48, the front sunshade roller sleeve 32, and the front sunshade retractor 33. As shown in Figure 22, the long shaft 46 of the front sunshade support serves as the common support shaft for the front sunshade right helical end 42, the front sunshade spring roller 43, the front sunshade long helical spring 44, the front sunshade support roller 45, the front sunshade roller sleeve 32, and the front sunshade retractor 33. This embodiment, through the combination of long and short shafts with long and short springs, achieves better retraction and support effects.

[0096] In this embodiment, the front sunshade spring roller 43 is made of foam material to wrap the long spiral spring 44 of the front sunshade as shown in Figure 20. The front sunshade roller sleeve 32 can rotate around the front sunshade spring roller 43, and the long spiral spring 44 can also rotate around the spiral groove at the right spiral end 42 of the front sunshade as shown in Figure 18. The front sunshade spring roller 43 can support the front sunshade roller sleeve 32 and also prevent the long spiral spring 44 of the front sunshade from directly contacting and rubbing against the front sunshade roller sleeve 32. The foam material can also absorb the noise generated by rotation.

[0097] This embodiment employs a dual sunshade structure with a front sunshade 4 and a rear sunshade 5. This reduces the diameter of the roller of a single sunshade, and the roller structure is positioned at the junction of the two sunshades, thus not occupying headroom in the front or second row, and without obstructing the driver's or passengers' view. The front sunshade 4 and rear sunshade 5 are each equipped with a motor, allowing both sunshades to be opened simultaneously, or the front or rear sunshades to be opened individually, meeting the different needs of front and rear passengers.

[0098] In this embodiment, both motors are located at the front end, which simplifies the rear structure of the sunshade without affecting the visibility of the front passengers, eliminating the need for additional structures. Furthermore, the pull cord mechanism is entirely built into the guide rail, allowing the rear structure of the sunshade to be thinner in the Z direction, increasing headroom for rear passengers. At the same time, the rear structure can be shorter in the X direction, increasing the X-direction light transmittance of the sunshade and providing a larger light-transmitting area for the rear passengers.

[0099] Example 2:

[0100] This embodiment provides a control method for an electric dual sunshade system, used to control the electric dual sunshade system of Embodiment 1. The electric dual sunshade system can switch between four working states through voice commands from the driver or passenger in the front row, large screen commands, and button commands from the rear passenger on the instrument panel: fully open state, fully closed state, front open and rear closed state, and front closed and rear open state.

[0101] The specific control process is as follows:

[0102] (1) With the front sunshade 4 and rear sunshade 5 fully open, they roll up simultaneously:

[0103] As shown in Figures 24-26, the front sunshade motor 12 rotates clockwise and the rear sunshade motor 13 rotates counterclockwise. The transmission gear of the front sunshade motor 12 drives the left pull cord 14 of the front sunshade to move to the left and backward, while the right pull cord 16 of the front sunshade moves to the right and backward, thereby driving the front sunshade 4 to move backward and roll up to the open state. The transmission gear of the rear sunshade motor 13 drives the left pull cord 15 of the rear sunshade to move to the right and forward, while the right pull cord 17 of the rear sunshade moves to the left and forward, thereby driving the rear sunshade 5 to move forward and roll up to the open state.

[0104] (2) When fully closed, both the front sunshade 4 and the rear sunshade 5 remain open:

[0105] As shown in Figure 27, the front sunshade motor 12 and the rear sunshade motor 13 keep the front sunshade 4 and the rear sunshade 5 fully extended to cover the panoramic glass via corresponding pull ropes.

[0106] (3) With the front open and the rear closed position, the front sunshade 4 rolls up and the rear sunshade 5 unfolds:

[0107] As shown in Figures 28-30, the front sunshade motor 12 rotates clockwise, and the transmission gear of the front sunshade motor 12 drives the left pull cord 14 of the front sunshade to move to the left and backward, while simultaneously driving the right pull cord 16 of the front sunshade to move to the right and backward, thereby driving the front sunshade 4 to move backward and roll up to the open state; the rear sunshade motor 13 prevents the rear sunshade 5 from rolling up, maintaining it in the open (closed) state.

[0108] (4) With the front closed and the rear open position, the front sunshade 4 unfolds and the rear sunshade 5 retracts:

[0109] As shown in Figures 31-33, the rear sunshade motor 13 rotates counterclockwise. The transmission gear of the rear sunshade motor 13 drives the left pull cord 15 of the rear sunshade to move to the right and forward, while simultaneously driving the right pull cord 17 of the rear sunshade to move to the left and forward. This causes the rear sunshade 5 to move forward and roll up to the open state. The front sunshade motor 12 prevents the front sunshade 4 from rolling up, keeping it in the open (closed) state.

[0110] This embodiment can meet the different needs of front and rear passengers by switching between the above four working states.

[0111] Example 3:

[0112] This embodiment provides a new energy vehicle equipped with the electric dual sunshade system described in Embodiment 1. The electric dual sunshade system is connected to the bracket of the left side panel of the vehicle body via the left pre-attached buckle 24 and to the bracket of the right side panel of the vehicle body via the right pre-attached buckle 25.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
