Description
Technical Field
[0001] This application relates to the field of automotive equipment, and more particularly to a roller shutter locking device and an automobile. Background Technology
[0002] As consumers increasingly demand flexibility and privacy in their car interiors, in-vehicle roller blinds (such as trunk covers and cargo box blinds) have become common features. These blinds typically slide or roll up along rails on both sides of the vehicle, used to conceal luggage, enhance aesthetics, and provide anti-theft security. Usually, clamping structures are installed on both sides of the rails, and each clamping structure is operated individually to move and clamp onto its corresponding rail, thus achieving a fixed position. However, in practical use, this structure requires multiple operations, making it cumbersome, time-consuming, and labor-intensive. Summary of the Invention
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a roller shutter locking device and automobile that can realize the linkage locking of the double-sided pressing parts, simplify the operation steps, and improve the convenience of user use.
[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a roller shutter locking device, the roller shutter locking device comprising: support; The first clamping member includes a first clamping part, a first adapter part, and a second adapter part connected in sequence, wherein the second adapter part is rotatably mounted on the bracket. The second clamping member is arranged at an interval from the first clamping member. The second clamping member includes a second clamping part, a third adapter part, and a fourth adapter part connected in sequence. The third adapter part is rotatably mounted on the bracket. A traction assembly, one end of which is connected to the first adapter, and the other end of which is away from the first adapter and connected to the fourth adapter.
[0005] In some embodiments of the first aspect, the traction assembly includes a slider and a traction rope. The slider is movably disposed on the bracket along the arrangement direction of the first clamping member and the second clamping member. The first adapter and the slider are movably connected along a first direction perpendicular to the arrangement direction. One end of the traction rope is connected to the slider, and the end of the traction rope away from the slider is connected to the fourth adapter.
[0006] In some embodiments of the first aspect, the slider has a groove that extends along the first direction; The first clamping member further includes a fifth adapter portion, which is disposed on the second clamping member and passes through the slide groove. The fifth adapter portion is rotatable relative to the slide groove and can also slide along the slide groove.
[0007] In some embodiments of the first aspect, the roller shutter locking device further includes an actuating member connected to the first clamping member, with the opposite ends of the actuating member and the first clamping member located on opposite sides of the bracket.
[0008] In some embodiments of the first aspect, the bracket has a receiving cavity on the side facing the lever; the lever drives the first clamping member to switch between a locked position and a released position; when the first clamping member is rotated to the locked position, the lever is received in the receiving cavity.
[0009] In some embodiments of the first aspect, the roller blind locking device includes a first guide rail and a second guide rail, the first clamping member corresponds to the first guide rail, the second clamping member corresponds to the second guide rail, and the bracket is slidably disposed relative to the first guide rail and the second guide rail; When the first clamping member rotates relative to the bracket and drives the second clamping member to rotate relative to the bracket, the bracket can switch between a locked state and a released state. When the bracket is in the locked state, the first clamping member abuts against the first guide rail and forms a sliding resistance, and the second clamping member abuts against the second guide rail and forms a sliding resistance, thereby restricting the movement of the bracket relative to the first guide rail and the second guide rail.
[0010] In some embodiments of the first aspect, the first guide rail is a first rack, and the second guide rail is a second rack; the first clamping part has a first insert tooth, and the second clamping part has a second insert tooth; When the bracket is in the locked state, the first insert tooth engages with the first rack, and the second insert tooth engages with the second rack.
[0011] In some embodiments of the first aspect, both the first pressing part and the second pressing part are elastic structures.
[0012] In some embodiments of the first aspect, the first clamping part and the first adapter part are detachably connected, and the second clamping part and the second adapter part are detachably connected.
[0013] Secondly, embodiments of this application also provide a vehicle, the vehicle including a roller shutter and a roller shutter locking device as described in any of the above embodiments, wherein the bracket of the roller shutter locking device is mounted on the free end of the roller shutter.
[0014] The embodiments of this application have the following advantages: This application provides a roller shutter locking device that uses a traction assembly to link and coordinate a first and second clamping member that are spaced apart. In actual operation, the user only needs to apply force to the first or second clamping member, and the traction assembly will simultaneously drive the clamping member on the other side, thereby simultaneously clamping or releasing the guide rails on both sides. This combines multiple independent operations into a single continuous operation, significantly simplifying the user's workflow. Furthermore, since the clamping members on both sides can respond synchronously, the user does not need to move back and forth on both sides of the vehicle or apply force separately, especially in confined or inconvenient trunk / cargo space. The linkage structure also ensures the synchronicity of the movement of the clamping members on both sides, avoiding uneven clamping force on both sides or forgetting to lock / unlock on one side due to separate operation. Moreover, both the first and second clamping members are rotatably mounted on the same bracket via their respective adapters, and the traction assembly is connected between the first adapter and the fourth adapter. This layout integrates the transmission mechanism near the bracket, eliminating the need for a large external space and making it easy to arrange within the limited installation space of a vehicle.

[0024] Such as 1 and Figure 2 As shown, to solve the above-mentioned technical problems, this application provides a roller blind locking device, which includes a bracket 100, a first pressing member 200, a second pressing member 300, and a traction assembly 400. The first pressing member 200 includes a first pressing part 230, a first transition part 220, and a second transition part 210 connected in sequence, with the second transition part 210 rotatably mounted on the bracket 100. The second pressing member 300 is spaced apart from the first pressing member 200 and includes a second pressing part 310, a third transition part 320, and a fourth transition part 330 connected in sequence, with the third transition part 320 rotatably mounted on the bracket 100. One end of the traction assembly 400 is connected to the first transition part 220, and the end of the traction assembly 400 away from the first transition part 220 is connected to the fourth transition part 330.
[0025] In these embodiments, this embodiment provides a roller shutter locking device for a car trunk or cargo box.
[0026] The bracket 100 is fixedly installed on one end of the horizontal beam of the roller shutter, located between the guide rails on both sides of the vehicle body, and is used to support the entire first clamping member 200 and the second clamping member 300.
[0027] The first clamping part 230 is an arc-shaped or planar protruding structure used to abut against the inner side of the left guide rail and apply clamping force. The second adapter part 210 is rotatably mounted on the left side of the bracket 100 via a pin or hinge, allowing the first clamping member 200 to swing around this pivot point. The first adapter part 220 serves as an intermediate connecting section, connecting the first clamping part 230 and the second adapter part 210, and transmitting operating force.
[0028] The second clamping member 300 and the first clamping member 200 are spaced apart along the lateral direction of the bracket 100, and their structures are symmetrical but not necessarily identical. The second clamping part 310 is used to contact and clamp the inner side of the right guide rail. The third adapter part 320 is rotatably mounted on the right side of the bracket 100 via another pin, allowing the second clamping member 300 to swing around that point. The fourth adapter part 330 extends to the side closer to the first clamping member 200.
[0029] For example, the traction assembly 400 is a flexible connector, such as a wire rope, a strap, or a linkage mechanism. One end of the traction assembly 400 is fixedly connected to the first adapter 220 of the first clamping member 200, and the other end is connected to the fourth adapter 330 of the second clamping member 300. When the user applies an operating force in one direction, the force is transmitted through the traction assembly 400, causing the first clamping member 200 and the second clamping member 300 to swing synchronously in opposite directions: that is, when the first clamping member 230 presses the left guide rail to the left, the traction assembly 400 pulls the fourth adapter 330, causing the second clamping member 310 to simultaneously press the right guide rail to the right, thereby achieving double-sided linkage locking.
[0030] In the unlocked state, the user only needs to operate either clamping part with one hand to release the traction component 400 and drive the clamping part on the other side, so that both sides can be released from the guide rail at the same time, making it easy for the roller shutter to slide freely or roll up.
[0031] like Figure 1 As shown, in some embodiments, the traction assembly 400 includes a slider 410 and a traction rope 420. The slider 410 is movably mounted on the bracket 100 along the arrangement direction of the first and second clamping members. A first adapter 220 and the slider 410 are movably connected along a first direction perpendicular to the arrangement direction. One end of the traction rope 420 is connected to the slider 410, and the end of the traction rope 420 away from the slider 410 is connected to the fourth adapter 330.
[0032] Based on the aforementioned embodiments, in order to further improve transmission smoothness, reduce operating resistance and optimize spatial layout, this embodiment improves the structure of the traction component 400.
[0033] The bracket 100 is provided with a guide groove or guide rail structure along the arrangement direction (e.g., horizontal) of the first clamping member 200 and the second clamping member 300. The sliding member 410 is slidably disposed in the guide groove and can move freely back and forth in the arrangement direction. The sliding member 410 can be a metal slider, a plastic slide block, or a sliding unit with rollers, and a lubricating coating or rolling bearing can be provided between it and the guide groove to reduce friction.
[0034] Furthermore, along a first direction perpendicular to the laying direction (i.e., the vertical direction), the first adapter 220 and the sliding member 410 are movably connected via a vertical groove 411-pin engagement structure. Specifically, the sliding member 410 has a vertically extending oblong hole, and a connecting pin is fixed on the first adapter 220. This connecting pin passes through the oblong hole, allowing the first adapter 220 to slide vertically relative to the sliding member 410 and also to move the sliding member 410 in the laying direction. This structure allows the first clamping member 200 to have a certain degree of vertical displacement freedom during clamping or releasing, preventing the mechanism from jamming due to assembly errors or uneven guide rails.
[0035] One end of the traction rope 420 is fixedly connected to the sliding member 410, and the other end is connected to the fourth adapter 330 of the second clamping member 300. The traction rope 420 can be made of high-strength fiber rope, stainless steel wire rope or flexible steel strip, and has low elongation and high tensile strength.
[0036] When the user operates the first pressing part 230 to press down on the left guide rail, the first pressing member 200 swings clockwise around the second transition part 210, causing the first transition part 220 to move downward. Since the connecting pin slides in the oblong hole of the slider 410, this downward movement will push the slider 410 to move to the right along the guide groove; the rightward movement of the slider 410 pulls the fourth transition part 330 through the traction rope 420, causing the second pressing member 300 to swing counterclockwise around the third transition part 320, thereby driving the second pressing part 310 to press down on the right guide rail.
[0037] Conversely, during unlocking, if the first pressing part 230 is pulled upwards, the first transition part 220 moves upwards, and the sliding part 410 moves back to the left under the tension of the traction rope 420 or the action of the return spring, releasing the pulling force on the fourth transition part 330. The second pressing part 300 rebounds under its own weight or the action of the auxiliary elastic part, disengaging from the right guide rail. Since the actions on both sides are mechanically coupled to the traction rope 420 through the sliding part 410, simultaneous unlocking or locking on both sides can be achieved by operating only one side.
[0038] It should be noted that the above structural design allows the transmission mechanism to be as close as possible to the bracket 100, reducing the space occupied under the roller shutter and thus reducing the encroachment on the interior space of the carriage.
[0039] like Figure 1 As shown, in some embodiments, the slider 410 has a groove 411 that extends along the first direction. The first clamping member 200 also includes a fifth adapter portion disposed on the second clamping member 310. The fifth adapter portion passes through the groove 411 and is rotatable relative to the groove 411. The fifth adapter portion can also slide along the groove 411.
[0040] Based on the aforementioned embodiments, in order to further improve the coordination of the mechanism's movement and the compactness of the structure, this embodiment improves the connection method between the first clamping member 200 and the sliding member 410. The sliding member 410 is provided with a sliding groove 411, which extends along a first direction perpendicular to the arrangement direction of the first clamping member 200 and the second clamping member 300.
[0041] Accordingly, in addition to the first pressing part 230, the first adapter part 220 and the second adapter part 210, the first pressing member 200 also includes a fifth adapter part. The fifth adapter part is fixedly disposed on the side of the second adapter part 210 or the first pressing part 230 near the bracket 100, and its structure is a protruding pin, rivet or integrally formed column.
[0042] During installation, the fifth adapter is inserted into the groove 411 of the slider 410. This creates a dual degree of freedom of movement. Rotational freedom: Since the fifth transition part is fixedly connected to the first clamping member 200, and the sliding member 410 does not constrain its rotation, when the first clamping member 200 can rotate relative to the bracket 100 around the second transition part 210, the fifth transition part can rotate relative to it within the slide groove 411. Sliding freedom: At the same time, the fifth transition part can slide up and down along the extension direction of the slide groove 411 to adapt to the displacement changes during the pressing process.
[0043] The overall structure is more compact, making it suitable for space-constrained vehicle environments.
[0044] like Figure 5 As shown, in some embodiments, the roller shutter locking device further includes an actuating member 600, which is connected to a first pressing member 200. The ends of the actuating member 600 and the first pressing member 200 that are opposite to each other are located on both sides of the bracket 100.
[0045] Based on the aforementioned embodiments, in order to further improve the user's ease of operation, this embodiment adds a lever 600 to the roller shutter locking device.
[0046] The lever 600 is a lever-type or paddle-type operating component, typically made of plastic, metal, or composite materials, offering good feel and durability. The lever 600 is fixedly connected to or integrally formed with the first clamping component 200, creating a rigid linkage structure.
[0047] Crucially, the lever 600 and the first clamping member 200 are located on opposite sides of the bracket 100 and extend away from each other. Specifically, the first clamping member 200 (especially its first clamping portion 230) is located on the inner side of the bracket 100 (i.e., the side facing the vehicle body guide rail) for contacting and clamping against the left guide rail. The lever 600 extends from the outer side of the bracket 100 for the user to press or flick with their fingers.
[0048] For example, the second adapter 210 of the first clamping member 200 is rotatably mounted on the bracket 100 via a pin, and one end of the lever 600 is connected to the middle of the first clamping member 200 or near the second adapter 210, for example by welding, riveting, or integral injection molding. When the user presses down on the free end of the lever 600 from the outside, the lever 600 lifts the inner end of the first clamping member 200 upward around the pivot point on the bracket 100 (which may share the same pin with the second adapter 210), causing the first clamping member 230 to disengage from the left guide rail; at the same time, the second clamping member 300 is released synchronously by the traction component 400 (whether it is a direct pull rope, a slider 410 + traction rope 420, or other linkage form), realizing double-sided unlocking.
[0049] Conversely, when the reverse lever 600 is activated, the first clamping part 230 returns to its original position to clamp the guide rail, while the traction assembly 400 pulls the second clamping part 300 to complete the locking.
[0050] like Figure 5 As shown, in some embodiments, the bracket 100 has a receiving cavity on the side facing the lever 600. The lever 600 drives the first clamping member 200 to switch between a locked position and a released position. When the first clamping member 200 rotates to the locked position, the lever 600 is received within the receiving cavity.
[0051] Based on the aforementioned embodiments, in order to further improve the overall appearance of the product and the safety of use, this embodiment optimizes the cooperation relationship between the bracket 100 and the lever 600.
[0052] The bracket 100 has a receiving cavity on the side facing the lever 600 (i.e., the outer side, facing the interior of the carriage or the outer surface of the roller shutter end cover). The receiving cavity is a recessed structure whose shape matches the outer contour of the lever 600. It is usually arc-shaped, rectangular or streamlined groove that conforms to the human finger pressing habit, and its depth is sufficient to accommodate the main body of the lever 600.
[0053] The lever 600 is linked to the first clamping member 200 and can drive the first clamping member 200 to switch between the locked position and the released position.
[0054] When the user is not operating, the first clamping member 200 is in the locked position: at this time, the first clamping part 230 clamps the left guide rail, and the second clamping member 300 simultaneously clamps the right guide rail, and the roller shutter is reliably fixed. At the same time, the lever member 600 rotates to the lowest position due to the reset action of the linkage mechanism (such as a reset spring or its own weight), and is completely or mostly housed in the receiving cavity. Its outer surface is basically flush with or slightly lower than the outer side of the bracket 100, forming a flat and simple appearance.
[0055] When the user needs to unlock, they can use their finger to move the lever 600 from the outside, causing it to rotate upwards / outwards against the reset force. This causes the first clamping member 200 to swing around its pivot point, disengage from the guide rail, and enter the released position. At this time, part of the lever 600 extends out of the receiving cavity, making it easier for the user to apply force.
[0056] For example, the receiving groove is provided with an elastic snap-fit part, such as an elastic buckle, for snapping the lever 600 that enters the receiving groove, so that it is kept in the locked position.
[0057] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the roller blind locking device includes a first guide rail 700 and a second guide rail 500, a first pressing member corresponding to the first guide rail 700, a second pressing member corresponding to the second guide rail 500, and a bracket 100 that can be slidably arranged relative to the first guide rail 700 and the second guide rail 500. When the first clamping member 200 rotates relative to the bracket 100 and drives the second clamping member 300 to rotate relative to the bracket 100, it can drive the bracket 100 to switch between a locked state and a released state. When the bracket 100 is in the locked state, the first clamping member 200 abuts against the first guide rail 700 and forms a sliding resistance, and the second clamping member 300 abuts against the second guide rail 500 and forms a sliding resistance, so as to restrict the movement of the bracket 100 relative to the first guide rail 700 and the second guide rail 500.
[0058] Based on the aforementioned embodiments, this embodiment further clarifies the installation structure of the roller shutter locking device in the vehicle.
[0059] The first guide rail 700 and the second guide rail 500 are respectively fixed to the inner walls of the left and right sides of the trunk or cargo box of the vehicle, extending along the longitudinal direction of the vehicle (i.e., the direction of the roller blind's unfolding / retracting). The bracket 100 spans between the first guide rail 700 and the second guide rail 500, and its left and right ends are respectively provided with sliders, rollers or sliding sleeve structures (not shown), so that the bracket 100 can slide relative to the first guide rail 700 and the second guide rail 500, thereby driving the entire roller blind assembly to unfold or retract.
[0060] The first clamping member 200 and the second clamping member 300 are respectively disposed on the left and right sides of the bracket 100: the first clamping member 200 is used to cooperate with the first guide rail 700. The second clamping member 300 is used to cooperate with the second guide rail 500.
[0061] When the user operates the lever 600 (or directly acts on the first clamping member 200), the first clamping member 200 rotates relative to the bracket 100 around its rotation fulcrum (such as the second adapter 210), and at the same time, the second clamping member 300 is driven to rotate synchronously in the opposite direction relative to the bracket 100 through the traction assembly 400.
[0062] Locked State: When the first clamping member 200 rotates to the clamping position, its first clamping part 230 tightly abuts against the inner side (or a specific clamping surface) of the first guide rail 700. Simultaneously, the second clamping part 310 of the second clamping member 300 synchronously abuts against the inner side of the second guide rail 500. Both apply sufficient positive pressure to the guide rails, thereby generating significant sliding friction resistance. This resistance is sufficient to resist vibrations during vehicle operation or minor external forces, limiting the movement of the bracket 100 relative to the first guide rail 700 and the second guide rail 500, thus achieving reliable positioning and locking of the roller blind.
[0063] Released state: When the lever 600 is pressed, the first clamping member 200 and the second clamping member 300 rotate synchronously and disengage from their respective guide rail surfaces, greatly reducing frictional resistance. The bracket 100 can then slide freely along the first guide rail 700 and the second guide rail 500 under the user's pull, completing the operation of raising and lowering the roller blind.
[0064] like Figure 2 As shown, in some embodiments, the first guide rail 700 is a first rack, and the second guide rail 500 is a second rack; the first pressing part 230 has a first insert tooth, and the second pressing part 310 has a second insert tooth; When the bracket 100 is in the locked state, the first insert tooth engages with the first rack, and the second insert tooth engages with the second rack.
[0065] Based on the aforementioned embodiments, in order to further improve the locking reliability, this embodiment has made structural improvements to the fit between the guide rail and the clamping part.
[0066] The first guide rail 700 is a first rack that extends longitudinally along the vehicle, and its inner surface is provided with a first tooth structure, such as straight teeth, helical teeth, or trapezoidal teeth, arranged continuously or intermittently. Correspondingly, the second guide rail 500 is a second rack, and its inner surface is provided with a second tooth structure that is the same as or symmetrical to the first tooth structure.
[0067] Correspondingly, the first clamping part 230 of the first clamping member 200 is provided with a first insert tooth, and the second clamping part 310 of the second clamping member 300 is provided with a second insert tooth. The tooth profile, module, pitch and other parameters of the first insert tooth and the second insert tooth are matched with the first rack and the second rack to ensure reliable meshing.
[0068] Locked State: When the user releases the lever 600, the first clamping member 200 and the second clamping member 300 rotate towards the corresponding guide rail direction, causing the first insert tooth to insert into and engage with the tooth groove of the first rack, while the second insert tooth inserts into and engages with the tooth groove of the second rack. At this time, the movement of the bracket 100 in the longitudinal direction of the vehicle is mechanically limited, and it cannot slide along the guide rail. Even if subjected to large external forces or vibrations, it will not displace, achieving rigid and slip-free locking.
[0069] Released state: When the user reverses the lever 600, the first clamping member 200 rotates in the opposite direction, and the second clamping member 300, under the action of gravity or spring force, causes the first and second insert teeth to disengage from the tooth grooves of the rack, releasing the mechanical constraint. At this time, the bracket 100 can slide freely along the first and second racks, facilitating the unfolding or rewinding of the roller blind.
[0070] For example, both the first and second inserts can be configured as single-tooth or multi-tooth structures. In particular, a multi-tooth design can improve load-bearing capacity.
[0071] For example, the tooth profiles of the first and second racks can be asymmetrical, such as a ratchet structure, to achieve unidirectional locking.
[0072] In some embodiments, both the first pressing part 230 and the second pressing part 310 are elastic structures.
[0073] Based on the aforementioned embodiments, in order to further improve the locking reliability, this embodiment optimizes the materials and structure of the first pressing part 230 and the second pressing part 310.
[0074] This elastic structure can be implemented using any one or a combination of the following methods: The clamping part is made entirely of an elastic material, such as thermoplastic elastomer, silicone, polyurethane, or rubber; The clamping part is made of metal or hard plastic, but its root is designed with an elastic arm, cantilever beam, corrugated section or spring plate so that it can undergo controllable deformation when subjected to force. A rigid skeleton is covered with a soft, elastic layer (for contacting guide rails or racks).
[0075] When the first pressing part 230 and the second pressing part 310 abut against the first guide rail 700 and the second guide rail 500, their elastic structure undergoes slight compression deformation under the action of positive pressure, increasing the actual contact area and improving the stability of the friction coefficient; at the same time, it can absorb the slight unevenness or assembly deviation of the guide rail surface, avoid point contact or jumping caused by rigid contact, and make locking more stable and quiet.
[0076] When the first tooth engages with the first rack, if there is a slight misalignment, the elastic structure allows the tooth to deflect or compress slightly, achieving adaptive engagement. Once engaged, the elastic restoring force provides additional preload to prevent loosening or disengagement. Furthermore, the elastic structure cushions impact loads during vehicle vibrations, reducing metal fatigue and noise.
[0077] like Figure 1 As shown, in some embodiments, the first clamping part 230 and the first adapter part 220 are detachably connected, and the second clamping part 310 and the second adapter part 210 are detachably connected.
[0078] Based on the aforementioned embodiments, in order to further improve the maintainability, replaceability and multi-scenario adaptability of the product, this embodiment has adopted a modular design for the internal connection method of the first clamping member 200 and the second clamping member 300.
[0079] The first pressing part 230 and the first adapter part 220 are detachably connected, and the second pressing part 310 and the third adapter part 320 are also detachably connected.
[0080] The specific implementation methods of detachable connection include, but are not limited to: snap-fit connection, threaded connection, pin shaft with elastic retaining ring or cotter pin to achieve quick assembly and disassembly or magnetic connection.
[0081] like Figure 2 As shown, in some embodiments, this application also provides a car, which includes a roller shutter and a roller shutter locking device, wherein a bracket 100 of the roller shutter locking device is mounted on the free end of the roller shutter.
[0082] Based on any of the aforementioned roller shutter locking device embodiments, this application also provides an automobile to demonstrate the integrated application of the locking device in an actual product.
[0083] The automobile includes a body structure (not shown), a trunk or cargo compartment, a roller shutter, and a roller shutter locking device as described in any of the above embodiments.
[0084] The roller blind is a retractable covering device. One end is fixed to the rear panel or roof beam of the vehicle (i.e., the fixed end), and the other end is a free end. When in use, it can be pulled forward along the guide rails on both sides of the vehicle to cover the luggage or cargo area, serving the functions of covering, preventing theft, and improving aesthetics.
[0085] Crucially, the bracket 100 of the roller shutter locking device is fixedly installed at the free end of the roller shutter.
[0086] Since the bracket 100 integrates components such as the first clamping member 200, the second clamping member 300, the traction assembly 400, and the lever member 600, once the roller shutter is pulled out to the desired position, the user only needs to perform a single operation (such as driving the lever member 600) to drive the clamping members on both sides to simultaneously clamp or engage the guide rails on both sides of the vehicle body, achieving rapid locking of the free end. Unlocking is also done with a single button release, allowing the roller shutter to smoothly rewind.
[0087] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0088] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
