Description

Technical Field

[0001] The invention belongs to the field of automobile sunroofs, and in particular relates to a sunroof safety blocking net mechanism for automobiles that is anti-smashing and anti-leaking, and a method for preventing automobile sunroofs from being smashed and anti-leaking. Background Art

[0002] Traditional vehicles with built-in sunroofs are equipped with a baffle below the sunroof to block the sun, which can be closed manually or automatically. However, after the car owner gets out of the car, closes the door and leaves, the car owner often forgets to close the baffle. At this time, if the sunroof glass is shattered by falling objects or human factors, the shattered sunroof glass will all fall into the car where the baffle is not closed. The glass fragments that fall into the car may enter the gaps on the moving or operating parts in the car, causing the movement of the moving or operating parts to be affected, thereby causing secondary damage to the vehicle. In addition, the glass fragments that fall into the car are also troublesome to clean up.

[0003] In view of the problem that the above-mentioned sunroof baffle cannot effectively and timely block the debris formed when the vehicle sunroof is damaged by falling objects from high altitude or human means, it is necessary to design a sunroof safety net mechanism that can automatically block the sunroof after the owner leaves and can be opened and closed manually.

[0004] The present invention designs a car anti-smashing and anti-leakage skylight safety screen mechanism to solve the above problems. Summary of the invention

[0047] like Figure 3 , 9 As shown in FIG. 12 , four trapezoidal guide blocks A39 are symmetrically mounted on the side of the slide bar B31. The four trapezoidal guide blocks A39 slide vertically in the four trapezoidal guide grooves A6 on the inner wall of the corresponding slide groove B5; Figure 4 , 8 As shown in 15, a trapezoidal guide block B50 is installed at the bottom of the wedge block B49, and the trapezoidal guide block B50 slides horizontally in the trapezoidal guide groove B8 at the bottom of the corresponding movable groove C7; Fig.13 As shown, a slide groove C32 is provided on the lower surface of the slide bar B31; Figure 6 , 12 As shown, a trapezoidal guide block C35 is installed on the slide bar C34, and the trapezoidal guide block C35 slides in the trapezoidal guide groove C33 at the top of the corresponding slide groove C32; two leaf springs 40 for resetting the slide bar C34 are symmetrically installed at both ends of the corresponding slide bar C34, and the two leaf springs 40 are located in the corresponding slide groove C32; one end of the leaf spring 40 is connected to the inner wall of the corresponding slide groove C32, and the other end is connected to the end face of one end of the corresponding slide bar C34. The cooperation between the trapezoidal guide groove A6 and the trapezoidal guide block B50 plays a positioning and guiding role in the vertical sliding of the slide bar B31 in the slide groove B5. The cooperation between the trapezoidal guide groove B8 and the trapezoidal guide block B50 plays a positioning and guiding role in the horizontal movement of the wedge block B49 in the movable groove C7. The cooperation between the trapezoidal guide groove C33 and the trapezoidal guide block C35 plays a positioning and guiding role in the horizontal sliding of the slide bar C34 on the lower surface of the slide bar B31.

[0048] like Figure 6 , 17 As shown, both side edges of the above-mentioned barrier net 12 are equipped with a pressing edge 21, and the limiting grooves 22 on the pressing edge 21 correspond one by one to the limiting grooves 22 on the side edges of the barrier net 12; Figure 5 , 17As shown in Figures 1 and 18, a support sleeve 37 is installed in each limit groove 22, and the top of the support sleeve 37 has a protrusion 38 with a sharp cross section; the protrusions 38 on two adjacent support bars are closely attached. The edge pressing 21 improves the hardness of the edge of the baffle net 12 to a certain extent, making it easier for the tooth block 36 on the slide bar C34 to smoothly enter the limit groove 22 on the edge of the baffle net 12 and effectively pull the two sides of the baffle net 12. The sharp protrusion 38 on the support sleeve 37 can guide the tooth block 36 to smoothly enter the limit groove 22 to pull the two sides of the baffle net 12.

[0049] like Figure 2 , 4 As shown, the above-mentioned spring A19, spring B43 and spring C51 are all tension springs; the upper end of the spring B43 is connected to the inner wall of the corresponding slide groove B5, and the lower end is connected to the corresponding slide bar B31; one end of the spring C51 is connected to the corresponding wedge block C, and the other end is connected to the inner wall of the corresponding movable groove C7.

[0050] like Figure 2 , 21 As shown, a dial plate A52 is installed in the middle of the lower surface of the wedge plate B16, and a dial plate B30 is installed in the middle of the lower surface of the slide bar A13; the dial plate A52 and the dial plate B30 cooperate with the movable groove A3 on the side wall of the skylight 53; Figure 7 , 19 As shown in , 21, a tension spring plate 20 is installed on the upper side of each L plate A17; one end of the spring A19 is connected to the tension spring plate 20 on the same side, and the other end is connected to the upper surface of the same side end of the slide bar A13; Fig.11 , 15 As shown, the wedge block B49 is mounted on the corresponding slider 44 via the L rod 48.

[0051] like Figure 2 As shown, a gear A28 is installed on the output shaft of the electric drive mold, and the gear A28 is meshed with a gear B27 installed on the shaft A26.

[0052] like Fig.16 As shown, the inner wall of the shaft hole in which the slider 44 and the shaft B46 rotate is provided with an annular groove 45; Fig.15 , 16 As shown, two spiral springs 47 are respectively located in the annular grooves 45 on the slider 44 on the same side; one end of the spiral spring 47 is connected to the shaft B46, and the other end is connected to the inner wall of the annular groove 45 on the corresponding slider 44.

[0053] like Fig.15As shown, the elastic coefficient of the above-mentioned volute spring 47 is smaller than the elastic coefficient of the spring C51, so as to avoid that during the process of the reel 11 driving the rotating shaft B46 to rotate, the volute spring 47 further compresses the stored energy, causing the shaft B46 to overcome the pulling force of the spring C51 through the volute spring 47, the slider 44 and the L rod 48 under the pull of the baffle 12 and drive the wedge block B49 to move.

[0054] In the present invention, the width of the inner wall of the support sleeve 37 along the movement direction of the baffle net 12 is greater than the width of the tooth block 36 along the movement direction of the baffle net 12, ensuring that during the resetting process of the slide bar A13, the tooth block 36 is reset vertically upward while the baffle net 12 can move relative to the tooth block 36 under the winding action of the reel 11, so that the tooth block 36 that is separated from the support sleeve 37 does not hinder the resetting movement of the baffle net 12.

[0055] The skylight module 10 in the present invention is prior art.

[0056] The electric drive module 29 in the present invention adopts the existing technology, which is mainly composed of a self-locking motor, a control unit and a reducer. The electric drive module 29 is electrically connected to the in-vehicle control system. The electric drive module 29 has an automatic identification and sensing function.

[0057] The working process of the present invention is as follows: the state in which the blocking net 12 is fully opened in the present invention is taken as its initial state; at this time, the blocking net 12 is completely wound on the drum 11 to block the skylight 53, and the slide bar A13 is located at the limit position of the slide groove A2 close to the drum 11; the spiral spring 47 is in a pre-compression energy storage state; the teeth 18 on the two L plates A17 are respectively engaged with the two synchronous belts 23, and the two springs A19 are both in a pre-stretched energy storage state; the wedge plate A15 is in contact with the wedge plate B16, and the upper surface of the wedge plate A15 is 1.5 meters away from the upper surface of the wedge plate B16. A certain distance from the top of the slide bar A13; the two springs B43 on each slide bar B31 are in the rope energy storage state, and the four trapezoidal guide blocks A39 on each slide bar B31 are located at the top limit position of the corresponding trapezoidal guide groove A6; the spring C51 on each wedge block B49 is in a stretched state, and the trapezoidal guide block B50 is located at the limit position of the corresponding trapezoidal guide groove B8; the lower end of the tooth block 36 on the slide bar B31 is higher than the upper surface of the slide bar A13; the inclined surface on the wedge block B49 is in close contact with the inclined surface on the corresponding wedge block A42.

[0058] When the car owner closes the door and locks the car, the control system in the car controls the operation of the electric drive module 29, and the electric drive module 29 drives the shaft A26 to rotate through the gear A28 and the gear B27, and the shaft A26 drives the two pulleys A25 to rotate synchronously, and the two pulleys A25 drive the two synchronous belts 23 to run synchronously; the two synchronous belts 23 that move synchronously drive the slide bar A13 and all the components installed in the slide bar A13 to slide synchronously in the direction of closing the skylight window 53 through the two L plates A17 that are meshed with them; the slide bar A13 pulls the blocking net 12, and the blocking net 12 drives the reel 11 to rotate and release the blocking net 12, and the reel 11 drives the shaft B46 to rotate relative to the two sliders 44, and the shaft B46 drives the two volute springs 47 to further compress and store energy; because the elastic coefficient of the spring C51 is much larger than the elastic coefficient of the volute spring 47, the volute spring 47 that is further compressed and stores energy at this time will not drive the wedge block B49 to move through the slider 44 and the L rod 48 under the pull of the blocking net 12.

[0059] When the slide bar A13 drives the blocking net 12 to completely cover the skylight 53, the slide bar A13 meets the inclined surface on the wedge block installed at one end of the slide bar B31; at this time, the compression of the spiral spring 47 reaches the limit, the shaft B46 stops rotating relative to the slider 44, the reel 11 stops rotating, and the blocking net 12 is no longer pulled out of the reel 11 by the moving slide bar A13. The sliding bar A13 that continues to move under the drive of the electric drive module 29 interacts with the inclined surface on the corresponding wedge block A42. The sliding bar A13 drives the slider 44 to slide synchronously through the retaining net 12, the reel 11, the shaft B46 and the scroll spring 47 compressed to the limit. The slider 44 drives the corresponding wedge block B49 to interact with the corresponding wedge block A42 through the corresponding L rod 48; the sliding bar A13 and the wedge block B49 respectively drive the sliding bar B31 to move vertically downward along the sliding groove B5 through the corresponding wedge block A42 and the L plate B41 at the same time; the sliding bar B31 drives the sliding bar C34 to move synchronously toward the edge of the retaining net 12 below.

[0060] When the plurality of tooth blocks 36 installed on the lower surface of the slide bar C34 simultaneously enter the plurality of support sleeves 37 installed on the edge of the retaining net 12, the control system controls the electric drive module 29 to stop running. The electric drive module 29 that stops running does not move the synchronous belt 23 under the action of external force because of the presence of the self-locking motor inside it; the two stretched springs A19 make the tooth patterns 18 on the two L plates A17 always mesh with the two synchronous belts 23, so that the reset movement of the slide bar A13 along the slide groove A2 is restricted; the two ends of the restricted and stationary slide bar A13 continue to maintain the corresponding two wedge blocks A42 The slide bar A13 drives the wedge block B49 to keep pressing down the corresponding wedge block A42 through a series of transmissions, so that the two slide bars B31 respectively drive the several tooth blocks 36 installed on the corresponding slide bar C34 through the corresponding slide bar C34 to continuously embed into the several support sleeves 37 on the edges of both sides of the barrier net 12 to form a support and pull on both sides of the barrier net 12, so as to avoid the phenomenon that the two sides of the barrier net 12 are not pulled when the broken skylight glass falls on the barrier net 12 and droop downward under the pressure of the glass fragments, thereby ensuring that the barrier net 12 effectively blocks all the glass fragments falling on it.

[0061] When the retaining net 12 needs to be recovered, the dial plate A52 is manually toggled, and the dial plate A52 drives the wedge plate B16 to slide horizontally, and the wedge plate B16 drives the wedge plate A15 to move vertically upward; the wedge plate A15 drives the two L plates A17 installed at both ends thereof to move vertically synchronously, and the two L plates A17 are simultaneously separated from the two synchronous belts 23, and the two springs A19 are further stretched to store energy; the state of the two L plates A17 being separated from the synchronous belts 23 is maintained, and the slide bar A13 is toggled in the direction of recovering the retaining net 12 through the dial plate B30; the slide bar A13 drives the two L plates A17 to move synchronously through a series of transmissions; under the reset action of the volute spring 47, the reverse rotating shaft B46 drives the retaining net 12 to move through the reel 11 rewinding; at the same time, under the reset action of the two springs C51, the two wedge blocks B49 move to the initial position and gradually release the restriction on the corresponding wedge block A42, and the two wedge blocks drive the two sliders 44 to reset through the corresponding L rods 48, and the reversely rotating reel 11 and shaft B46 are reset under the drive of the two sliders 44; at the same time, the reset slide A13 gradually releases the restriction on the corresponding two wedge blocks A42; the two slides B31 are gradually reset under the reset action of the corresponding two springs B43, and the two slides B31 drive the several tooth blocks 36 installed on the corresponding slide C34 through the corresponding slide C34 to gradually disengage from the corresponding support sleeve 37 and release the restriction on the movement of the baffle 12.

[0062] When the slide bar reaches its initial position, the force acting on the paddle plate A52 and the paddle plate B30 is removed. Under the resetting action of the two springs A19, the two tension spring plates 20 respectively drive the two L plates A to reset instantly relative to the slide bar A13. The two L plates A17 drive the wedge plate B16 and the paddle plate A52 to reset instantly relative to the slide bar A13 through the wedge plate A15. The teeth 18 on the two L plates A17 re-engage with the two synchronous belts 23.

[0063] When the barrier net 12 needs to be manually unfolded, the paddle A52 is manually toggled, and the paddle A52 drives the wedge plate B16 to slide horizontally, and the wedge plate B16 drives the wedge plate A15 to move vertically upward; the wedge plate A15 drives the two L plates A17 installed at both ends thereof to move vertically synchronously, and the two L plates A17 are simultaneously separated from the two synchronous belts 23, and the two springs A19 are further stretched to store energy; the state of the two L plates A17 being separated from the synchronous belts 23 is maintained, and the slide bar A13 is toggled in the direction of unfolding the barrier net 12 through the paddle B30; the slide bar A13 is passed through the paddle B30 to move vertically upward; the slide bar A13 is moved vertically upward; the two L plates A17 are ... Through a series of transmissions, the two L plates A17 are driven to move synchronously; the slide bar A13 pulls the baffle net 12, the baffle net 12 drives the reel 11 to rotate and release the baffle net 12, the reel 11 drives the shaft B46 to rotate relative to the two sliders 44, and the shaft B46 drives the two volute springs 47 to further compress and store energy; because the elastic coefficient of the spring C51 is much larger than the elastic coefficient of the volute spring 47, the volute spring 47 that is further compressed and stores energy will not drive the wedge block B49 to move through the slider 44 and the L rod 48 under the pull of the baffle net 12.

[0064] When the slide bar A13 drives the blocking net 12 to completely cover the skylight 53, the slide bar A13 meets the inclined surface on the wedge block installed at one end of the slide bar B31; at this time, the compression of the spiral spring 47 reaches the limit, the shaft B46 stops rotating relative to the slider 44, the reel 11 stops rotating, and the blocking net 12 is no longer pulled out of the reel 11 by the moving slide bar A13. The slide bar A13 continues to be driven to move through the dial plate B30 and interact with the inclined surface on the corresponding wedge block A42. The slide bar A13 drives the slider 44 to slide synchronously through the retaining net 12, the reel 11, the shaft B46 and the scroll spring 47 compressed to the limit. The slider 44 drives the corresponding wedge block B49 to interact with the corresponding wedge block A42 through the corresponding L rod 48; the slide bar A13 and the wedge block B49 respectively drive the slide bar B31 to move vertically downward along the slide groove B5 through the corresponding wedge block A42 and the L plate B41 at the same time; the slide bar B31 drives the slide bar C34 to move synchronously toward the edge of the retaining net 12 below.

[0065] When the plurality of tooth blocks 36 installed on the lower surface of the slide bar C34 simultaneously enter the plurality of support sleeves 37 installed on the edge of the retaining net 12, the forces acting on the shifting plate B30 and the shifting plate A52 are removed; under the resetting action of the two springs A19, the two tension spring plates 20 respectively drive the two L plates A to reset instantly relative to the slide bar A13, and the two L plates A17 drive the wedge plate B16 and the shifting plate A52 to reset instantly relative to the slide bar A13 through the wedge plate A15, and the tooth patterns 18 on the two L plates A17 re-engage with the two synchronous belts 23. Since the electric drive module 29 is not in operation at this time, the synchronous belt 23 will not move under the action of external force due to the presence of the self-locking motor inside it; the action of the two stretched springs A19 makes the teeth 18 on the two L plates A17 always mesh with the two synchronous belts 23, so that the reset movement of the slide bar A13 along the slide groove A2 is restricted; the two ends of the restricted and stationary slide bar A13 continue to press down on the corresponding two wedge blocks A42, and the slide bar A13 drives the wedge block B49 to keep pressing down on the corresponding wedge block A42 through a series of transmissions, so that the two slide bars B31 respectively drive the several tooth blocks 36 installed on the corresponding slide bar C34 through the corresponding slide bar C34 to continuously embed into the several support sleeves 37 on the edges of both sides of the baffle net 12 to form a support and pull on both sides of the baffle net 12.

[0068] The method for preventing the automobile sunroof from being smashed and leaked is as follows: the state in which the blocking net 12 is fully opened is taken as its initial state; at this time, the blocking net 12 is completely wound on the reel 11 to block the sunroof window 53, and the slide bar A13 is located at the limit position of the slide groove A2 close to the reel 11; the spiral spring 47 is in a pre-compression energy storage state; the teeth 18 on the two L plates A17 are respectively engaged with the two synchronous belts 23, and the two springs A19 are both in a pre-stretched energy storage state; the wedge plate A15 is in contact with the wedge plate B16, and the upper surface of the wedge plate A15 is 1.5 meters away from the upper surface of the wedge plate B16.

[0069] When the door is closed and the car is locked, the control system in the car controls the operation of the electric drive module 29, and the electric drive module 29 drives the shaft A26 to rotate through the gear A28 and the gear B27, and the shaft A26 drives the two pulleys A25 to rotate synchronously, and the two pulleys A25 drive the two synchronous belts 23 to run synchronously; the two synchronous belts 23 that move synchronously drive the slide bar A13 and all the components installed in the slide bar A13 to slide synchronously in the direction of closing the skylight window 53 through the two L plates A17 that are meshed therewith; the slide bar A13 pulls the blocking net 12, and the blocking net 12 drives the reel 11 to rotate and release the blocking net 12, and the reel 11 drives the shaft B46 to rotate relative to the two sliders 44, and the shaft B46 drives the two volute springs 47 to further compress and store energy; because the elastic coefficient of the spring C51 is much larger than the elastic coefficient of the volute spring 47, the volute spring 47 that is further compressed and stores energy will not drive the wedge block B49 to move through the slider 44 and the L rod 48 under the pull of the blocking net 12;

[0070] When the slider A13 drives the blocking net 12 to completely block the skylight 53, the slider A13 meets the inclined surface on the wedge block installed at one end of the slider B31; at this time, the compression of the volute spring 47 reaches the limit, the shaft B46 stops rotating relative to the slider 44, the reel 11 stops rotating, and the blocking net 12 is no longer pulled out of the reel 11 by the moving slider A13; the slider A13, which is driven by the electric drive module 29, interacts with the inclined surface on the corresponding wedge block A42, and the slider A13 moves.

[0071] When the plurality of tooth blocks 36 installed on the lower surface of the slide bar C34 simultaneously enter the plurality of support sleeves 37 installed on the edge of the retaining net 12, the control system controls the electric drive module 29 to stop running. The electric drive module 29 that stops running does not move the synchronous belt 23 under the action of external force because of the presence of the self-locking motor inside it; the two stretched springs A19 make the tooth patterns 18 on the two L plates A17 always mesh with the two synchronous belts 23, so that the reset movement of the slide bar A13 along the slide groove A2 is restricted; the two ends of the restricted and stationary slide bar A13 continue to maintain the corresponding two wedge blocks A42 The slide bar A13 drives the wedge block B49 to keep pressing the corresponding wedge block A42 downward through a series of transmissions, so that the two slide bars B31 respectively drive the several tooth blocks 36 installed on the corresponding slide bar C34 through the corresponding slide bar C34 to continuously embed into the several support sleeves 37 on the edges of the two sides of the barrier net 12 to form a support and pull on the two sides of the barrier net 12, so as to avoid the barrier net 12 drooping downward under the pressure of glass fragments because the two sides of the barrier net 12 are not pulled when the broken skylight glass falls on the barrier net 12, thereby ensuring that the barrier net 12 effectively blocks all glass fragments falling on it;

[0072] When the retaining net 12 needs to be recovered, the dial plate A52 is manually toggled, and the dial plate A52 drives the wedge plate B16 to slide horizontally, and the wedge plate B16 drives the wedge plate A15 to move vertically upward; the wedge plate A15 drives the two L plates A17 installed at both ends thereof to move vertically synchronously, and the two L plates A17 are simultaneously separated from the two synchronous belts 23, and the two springs A19 are further stretched to store energy; the state of the two L plates A17 being separated from the synchronous belts 23 is maintained, and the slide bar A13 is toggled in the direction of recovering the retaining net 12 through the dial plate B30; the slide bar A13 drives the two L plates A17 to move synchronously through a series of transmissions; under the reset action of the volute spring 47, the reverse rotating shaft B46 drives the retaining net 12 to move through the reel 11 At the same time, under the reset action of the two springs C51, the two wedge blocks B49 move to the initial position and gradually release the restrictions on the corresponding wedge blocks A42. The two wedge blocks drive the two sliders 44 to reset through the corresponding L rods 48, and the reel 11 and the shaft B46 that rotate in the opposite direction are reset under the drive of the two sliders 44; at the same time, the reset slide bar A13 gradually releases the restrictions on the corresponding two wedge blocks A42; the two slide bars B31 are gradually reset under the reset action of the corresponding two springs B43, and the two slide bars B31 drive the several tooth blocks 36 installed on the corresponding slide bar C34 through the corresponding slide bar C34 to gradually break away from the corresponding support sleeve 37 and release the restrictions on the movement of the baffle 12;

[0073] When the slide bar reaches the initial position, the force acting on the paddle A52 and the paddle B30 is removed. Under the reset action of the two springs A19, the two tension spring plates 20 respectively drive the two L plates A to reset relative to the slide bar A13 instantly. The two L plates A17 drive the wedge plate B16 and the paddle A52 to reset relative to the slide bar A13 instantly through the wedge plate A15. The tooth patterns 18 on the two L plates A17 mesh with the two synchronous belts 23 again.

[0074] When the barrier net 12 needs to be manually unfolded, the paddle A52 is manually toggled, and the paddle A52 drives the wedge plate B16 to slide horizontally, and the wedge plate B16 drives the wedge plate A15 to move vertically upward; the wedge plate A15 drives the two L plates A17 installed at both ends thereof to move vertically synchronously, and the two L plates A17 are simultaneously separated from the two synchronous belts 23, and the two springs A19 are further stretched to store energy; the state of the two L plates A17 being separated from the synchronous belts 23 is maintained, and the slide bar A13 is toggled in the direction of unfolding the barrier net 12 through the paddle B30; the slide bar A13 is passed through the paddle B30 to move vertically upward; the slide bar A13 is moved vertically upward; the two L plates A17 are ... Through a series of transmissions, the two L plates A17 are driven to move synchronously; the slider A13 pulls the blocking net 12, the blocking net 12 drives the reel 11 to rotate and release the blocking net 12, the reel 11 drives the shaft B46 to rotate relative to the two sliders 44, and the shaft B46 drives the two volute springs 47 to further compress and store energy; because the elastic coefficient of the spring C51 is much larger than the elastic coefficient of the volute spring 47, the volute spring 47 that is further compressed and stores energy will not drive the wedge block B49 to move through the slider 44 and the L rod 48 under the pull of the blocking net 12;

[0075] When the slider A13 drives the blocking net 12 to completely block the skylight 53, the slider A13 meets the inclined surface on the wedge block installed at one end of the slider B31; at this time, the compression of the spiral spring 47 reaches the limit, the shaft B46 stops rotating relative to the slider 44, the reel 11 stops rotating, and the blocking net 12 is no longer pulled out of the reel 11 by the moving slider A13; the slider A13 continues to move through the dial plate B30 and interacts with the inclined surface on the corresponding wedge block A42, and the slider A13 moves. A13 drives the slider 44 to slide synchronously through the baffle 12, the reel 11, the shaft B46 and the scroll spring 47 compressed to the limit, and the slider 44 drives the corresponding wedge block B49 to interact with the corresponding wedge block A42 through the corresponding L rod 48; the slider A13 and the wedge block B49 drive the slider B31 to move vertically downward along the slide groove B5 through the corresponding wedge block A42 and the L plate B41 respectively; the slider B31 drives the slider C34 to move synchronously toward the edge of the baffle 12 below;

[0076] When the plurality of tooth blocks 36 installed on the lower surface of the slide bar C34 simultaneously enter the plurality of support sleeves 37 installed on the edge of the retaining net 12, the forces acting on the paddle plate B30 and the paddle plate A52 are removed; under the reset action of the two springs A19, the two tension spring plates 20 respectively drive the two L plates A to reset instantly relative to the slide bar A13, and the two L plates A17 drive the wedge plate B16 and the paddle plate A52 to reset instantly relative to the slide bar A13 through the wedge plate A15, and the tooth patterns 18 on the two L plates A17 are re-engaged with the two synchronous belts 23; because the electric drive module 29 is not in operation at this time, the synchronous belt 23 will not be locked under the action of external force because of the presence of the self-locking motor inside it. Movement occurs; the action of the two stretched springs A19 makes the teeth 18 on the two L plates A17 always mesh with the two synchronous belts 23, so that the reset movement of the slide bar A13 along the slide groove A2 is restricted; the two ends of the restricted and stationary slide bar A13 continue to press down the corresponding two wedge blocks A42, and the slide bar A13 drives the wedge block B49 to keep pressing down the corresponding wedge block A42 through a series of transmissions, so that the two slide bars B31 respectively drive the several tooth blocks 36 installed on the corresponding slide bar C34 through the corresponding slide bar C34 to continuously embed into the several support sleeves 37 on the edges of both sides of the baffle net 12 to form a support and pull on both sides of the baffle net 12.
