A multifunctional outdoor sunshade device

Abstract

This invention discloses a multifunctional outdoor sunshade device, relating to the field of outdoor sunshade technology. It includes sunshade roll material, a mounting frame, and a winding elastic element. The mounting frame is equipped with a roller, a support mechanism, and a self-locking mechanism. The self-locking mechanism has two states: a first state where the roller is locked to prevent the sunshade roll material from being wound by clamping any designated position on the roller or a component thereon; multiple designated positions constitute multiple rotation angles of the roller. The second state where the roller is unlocked to allow the sunshade roll material to be wound by releasing the clamp on the roller or a component thereon. This outdoor sunshade device uses the aforementioned self-locking mechanism, allowing for easy locking after unwinding the sunshade roll material. It has good unwinding and stopping capabilities, can stop at multiple points, and offers better functionality. Combined with the winding elastic element, it makes unwinding and rewinding more convenient.

Description

Technical Field

[0001] This invention relates to the field of outdoor sunshade technology, specifically to a multifunctional outdoor sunshade device. Background Technology

[0002] The main way to provide shade outdoors is by using awnings. Awnings can usually be unfolded and rotated to be retracted. They can be operated by hand or by electric retraction. Due to the large size, heavy weight and high price of electric awnings, manually retractable awnings are more common.

[0003] The Chinese utility model patent with patent number 202222444220.6, "A support mechanism and vehicle sunshade device for vehicle sunshade", solves the technical problem that the existing sunshade is cumbersome to support and store, and it is difficult for one person to open or store the sunshade.

[0004] However, with the "locking assembly for limiting the rotation range of the second folding arm relative to the first folding arm with the first pivot as the rotation center" and the "second elastic member for driving the sunshade cloth to roll onto the roller", if the user wants to lock the sunshade cloth after pulling it out to prevent the second elastic member from causing the sunshade cloth to roll back, the user needs to pull the sunshade cloth to its maximum position so that the locking assembly can lock it. That is, in actual use, the sunshade can only have one unfolded area. For users who need to adapt to different outdoor environments, especially for campers, users sometimes cannot pull the sunshade cloth to its maximum position due to limited space. Users sometimes only need a small sunshade area or an adjustable sunshade area, so its functionality is very low. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional outdoor sunshade device, comprising a sunshade roll and a mounting frame. A roller for winding the sunshade roll is rotatably mounted on the mounting frame. A support mechanism is provided on the mounting frame to support the sunshade roll when it is in an unrolled state. A winding elastic element is provided on the sunshade roll, the mounting frame, or the roller for driving the sunshade roll to wind onto the roller. When the roller is rotated to unroll the sunshade roll, the winding elastic element is in an elastic deformation state or an increased elastic deformation state. The device also includes a self-locking mechanism with two states: a first state where the roller is locked to prevent winding of the sunshade roll by clamping any designated position on the roller or a component on the roller, with multiple designated positions constituting multiple rotation angles of the roller; and a second state where the roller is unlocked to allow winding of the sunshade roll by releasing the clamping of the roller or a component on the roller.

[0007] As a further aspect of the present invention: the self-locking mechanism includes...

[0008] The first mating wheel is mounted on the winding roller. Multiple mating grooves are formed in a ring at intervals on the outer circumference of the first mating wheel. The mating grooves indicate the designated positions.

[0009] A swing component is mounted on a mounting frame. The rotation center of the swing component is rotatably connected to the mounting frame. The distal part of the swing component is close to the outer circumferential surface of the first mating wheel. A swing locking block corresponding to the mating groove is connected to the distal part of the swing component.

[0010] The swing reset elastic element is used to make the swinging component tend to return to the swing center after swinging when the swinging component swings.

[0011] The self-locking and unlocking conversion component includes a second mating wheel rotatably connected to the mounting bracket. The outer circumference of the second mating wheel is formed with a plurality of locking grooves and a plurality of unlocking grooves in annular intervals. The locking grooves and unlocking grooves are staggered. A travel limit block is formed in the locking groove. Both the locking groove and the unlocking groove have two different force-bearing sides adjacent to the adjacent groove. The two different force-bearing sides are the positive side and the negative side, respectively.

[0012] The swing component is also equipped with a conversion lever and a locking lever;

[0013] The shifting block is used to shift the positive side of the locking groove or unlocking groove and engage with it accordingly when the swinging member rotates in the first direction;

[0014] The locking lever is used to move the opposite side of the locking groove or unlocking groove and engage with it accordingly when the swinging member rotates in the second direction.

[0015] When the locking block is engaged in the locking groove, the travel limit block is used to abut against the locking block to limit the amount by which the locking block is engaged in the locking groove; when the travel limit block abuts against the locking block, the travel limit block restricts the swing member from continuing to rotate in the second direction, and the swing locking block on the swing member is engaged in one of the mating grooves on the first mating wheel but has not completely disengaged. At this time, the roller is allowed to unwind the sunshade roll, and the roller is restricted from winding the sunshade roll.

[0016] As a further aspect of the present invention: the sum of the amount of movement of the switching block to the positive side and the amount of movement of the locking block to the negative side is greater than or equal to the distance between two adjacent positive sides and / or greater than or equal to the distance between two adjacent negative sides, and less than the distance between three adjacent positive sides and / or less than the distance between three adjacent negative sides.

[0017] As a further aspect of the present invention: the swing member has a slot formed thereon, and the swing reset elastic member includes a spring sheet inserted into the slot, the two wings of the spring sheet extending out of the slot and cooperating with the mounting bracket, and the two wings of the spring sheet respectively forming a first elastic reset part and a second elastic reset part that cooperate with the mounting bracket.

[0018] As a further aspect of the present invention: along the axial direction of the second mating wheel, the locking groove is divided into a first-end locking groove and a second-end locking groove; the travel limiting block is formed on the bottom wall of the first-end locking groove or on the bottom wall of the second-end locking groove; the locking lever is engaged with the groove portion having the travel limiting block, and the conversion lever is engaged with the groove portion without the travel limiting block.

[0019] As a further aspect of the present invention: the back side of the locking groove is formed with a relief slope that is inclined toward the front side of the adjacent unlocking groove; the travel limit block has an outwardly convex travel supplement arc surface that engages with the relief slope, and an abutment surface that engages with the outwardly convex travel supplement arc surface, the abutment surface being used to abut against the locking block.

[0020] As a further aspect of the present invention: the support mechanism includes a connecting block disposed on the mounting frame, the connecting block being provided with a folding component, the connecting block being connected to a support member through the folding component, and the sunshade roll being connected to the support member.

[0021] As a further aspect of the present invention: the folding assembly is composed of an even number of support arms that are connected end to end in sequence, with the first support arm being rotatably connected to the connecting block and the last support arm being rotatably connected to the support block.

[0022] As a further aspect of the present invention: a stroke supplement guide rail is formed on the mounting bracket, and a slider is slidably mounted on the stroke supplement guide rail. The sliding direction of the slider is the same as the stretching direction of the folding component, and the connecting block is connected to the slider.

[0023] As a further aspect of the present invention: a support rod is rotatably connected to the support member, the support rod being a telescopic rod; there are two support rods, and the two support rods are staggered when rotated to retract.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] This outdoor sunshade device adopts the aforementioned self-locking mechanism, which can be easily locked after the sunshade roll is pulled out and unrolled. It has good unwinding and stopping capability, can stop at multiple points, has better functionality, and is more convenient to pull out and rewind when combined with the winding elastic element.

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] In the embodiments of this invention, please refer to Figure 1-13 A multifunctional outdoor sunshade device includes a sunshade roll 1 and a mounting frame 2. The mounting frame 2 is rotatably equipped with a roller 3 for winding the sunshade roll 1. The mounting frame 2 is also equipped with a support mechanism 4 for supporting the sunshade roll 1 when the sunshade roll 1 is in the unrolled state (also known as the unfolded state).

[0050] The sunshade roll 1, the mounting frame 2, or the roller 3 is provided with a winding elastic element 5 for driving the sunshade roll 1 to be wound onto the roller 3. When the roller 3 is rotated to make the sunshade roll 1 unwound, the winding elastic element 5 is in an elastic deformation state or in an increased elastic deformation state. When the external force is removed, the deformation of the winding elastic element 5 is restored, which drives the roller 3 to wind up the sunshade roll 1.

[0051] This multifunctional outdoor sunshade device also includes a self-locking mechanism 6, which has two states.

[0052] The first state is the locked state, which restricts the winding of the sunshade roll 1 by clamping the roller 3 or any designated position of the component on the roller 3. The multiple designated positions constitute multiple rotation angles of the roller 3.

[0053] The second state is the unlocked state, which allows the roller 3 to wind the sunshade roll 1 by unfastening the roller 3 or the components on the roller 3.

[0054] Furthermore, the self-locking mechanism 6 includes a first mating wheel 61, a swing member 62, a swing reset elastic member 63, and a self-locking unlocking conversion member 64.

[0055] The first mating wheel 61 is installed on the winding roller 3, such as Figure 4 , 5 As shown in Figures 6 and 6, the first mating wheel 61 and the roller 3 are coaxially arranged. Multiple mating grooves 611 are formed in a ring at intervals on the outer circumference of the first mating wheel 61. The mating grooves 611 are indicated by the specified positions mentioned above.

[0056] The swing member 62 is mounted on the mounting bracket 2. The rotation center of the swing member 62 is rotatably connected to the mounting bracket 2. The distal part of the swing member 62 is close to the outer circumferential surface of the first mating wheel 61. A swing locking block 621 corresponding to the mating groove 611 is connected to the distal part of the swing member 62.

[0057] The rotation direction of the swing member 62 relative to the mounting frame 2 is the same as or opposite to the rotation direction of the roller 3 relative to the mounting frame 2. That is, the rotation direction of the swing member 62 relative to the mounting frame 2 is the same as or opposite to the rotation direction of the first mating wheel 61 relative to the mounting frame 2. When the swing member 62 rotates up and down, the first mating wheel 61 rotates up and down, and the swing locking block 621 on the swing member 62 can engage with the mating groove 611 on the first mating wheel 61 to form a meshing structure. Figure 6 , 7 As shown, when the swing locking block 621 on the swing member 62 is engaged in one of the mating grooves 611 on the first mating wheel 61, the continued rotation of the roller 3 will drive the swing member 62 to rotate.

[0058] When the swing lock block 621 is engaged in one of the mating grooves on the first mating wheel 61, rotating the first mating wheel 61 causes the swing member 62 to rotate in the first direction and rotating the first mating wheel 61 causes the swing member 62 to rotate in the second direction. The swing member 62 rotates back and forth accordingly, that is, it swings. The first direction and the second direction are opposite to each other.

[0059] When the first mating wheel 61 drives the swing member 62, the swing amount of the swing member 62 is actually determined by the thickness and height of the swing lock block 621 and the width of the mating groove 611.

[0060] The first mating wheel 61 drives the swing member 62 through the inner wall of the mating groove 611 until the swing locking block 621 completely disengages from the mating groove 611, thus obtaining the maximum swing amount when the swing member 62 is driven only by the first mating wheel 61.

[0061] When the swing member 62 swings, it forms a swing center. That is, relative to the swing center, the amount of swing exceeding the first direction and the amount of swing exceeding the second direction are the same or substantially the same. When the maximum amount of swing exceeding the first direction is reached, the swing locking block 621 completely disengages from the mating groove 611.

[0062] The swing reset elastic element 63 is used to make the swing element 62 tend to return to the swing center after the swing element 62 swings.

[0063] Preferably, the swing member 62 has a slot 624 formed on it, and the swing reset elastic member 63 includes a spring that is inserted into the slot 624. The two wings of the spring extend out of the slot 624 and cooperate with the mounting bracket 2. The two wings of the spring respectively form a first elastic reset part 631 and a second elastic reset part 632.

[0064] The unidirectional bending elastic reset characteristic of the spring can be utilized to make the first elastic reset part elastic reset after exceeding the swing amount in the first direction, and the second elastic reset part elastic reset after exceeding the swing amount in the second direction. Structurally, for example, the mounting bracket can only block one side of the first elastic reset part and only block one side of the second elastic reset part.

[0065] Alternatively, the characteristic of the spring that can be bent and elastically reset in both directions can be utilized, so that the first elastic reset part and the second elastic reset part can simultaneously serve as elastic reset after exceeding the swing amount in the first direction and elastic reset after exceeding the swing amount in the second direction. Structurally, for example, the mounting bracket can block both sides of the first elastic reset part and both sides of the second elastic reset part.

[0066] The swing reset elastic element 63 is designed such that after the first mating wheel 61 is rotated to completely disengage the swing locking block 621 from the mating groove 611, the swing reset elastic element 63 is in an elastic deformation state. When the first mating wheel 61 is rotated in the opposite direction and corresponds to the swing locking block 621 in any mating groove, the reset action of the swing reset elastic element 63 causes the swing locking block 621 to continue to be engaged in the mating groove, so that the swing element 62 can swing in the opposite direction.

[0067] The swing reset elastic element 63 is used to ensure that after the swing lock block 621 is disengaged from the mating groove, when the first mating wheel 61 is rotated in the opposite direction and the swing lock block 621 is aligned with any mating groove, the swing lock block 621 can continue to engage with the mating groove on the first mating wheel 61, instead of being unable to engage after the swing lock block 621 is disengaged from the mating groove, thus ensuring its stable operation.

[0068] The self-locking / unlocking conversion component 64 includes a second mating wheel 641 rotatably connected to the mounting bracket 2. The outer circumference of the second mating wheel 641 is annularly spaced with multiple locking grooves 642 and multiple unlocking grooves 643. The locking grooves 642 and unlocking grooves 643 are staggered. A travel limit block 644 is formed within the locking groove 642. Both the locking groove 642 and the unlocking groove 643 have two different force-bearing sides adjacent to the adjacent groove. These two different force-bearing sides are a front side 645 and a back side 646.

[0069] The rotation direction of the second mating wheel 641 relative to the mounting bracket 2 is the same as or opposite to the rotation direction of the swing member 62 relative to the mounting bracket 2.

[0070] The swing member 62 is provided with a changeover block 622 and a locking block 623.

[0071] The shifting block 622 is used to shift the positive side 645 of the locking groove or unlocking groove and engage with it when the swing member 62 rotates in the first direction.

[0072] The locking lever 623 is used to actuate the opposite side 646 of the locking groove or unlocking groove and engage with it when the swing member 62 rotates in the second direction.

[0073] When the locking block 623 is engaged in the locking groove 642, the travel limit block 644 is used to abut against the locking block 623 to limit the amount by which the locking block 623 is engaged in the locking groove 642.

[0074] The travel limit block 644 is configured to avoid the changeover block 622, and the travel limit block 644 is configured to limit the locking block 623. That is, the travel limit block 644 will not block the changeover block 622 and will not limit the amount by which the changeover block 622 is engaged in the locking groove 642, while the travel limit block 644 will block the locking block 623, thereby limiting the amount by which the locking block 623 is engaged in the locking groove 642.

[0075] The blocking of the locking block 623 by the travel limit block 644 will not reduce the amount of movement of the locking block 623 on the opposite side 646. That is, the locking block 623 has completed the movement of the opposite side 646 before the travel limit block 644 blocks the locking block 623. Or, the reduction in movement caused by the blocking of the locking block 623 by the travel limit block 644 does not affect the required movement amount.

[0076] The travel limit block 644 blocks the locking block 623, affecting the amount of swing of the swinging component in the second direction.

[0077] The sum of the amount of movement of the shifting block on the positive side and the amount of movement of the locking block on the negative side is the distance between two adjacent positive sides and / or the distance between two adjacent negative sides, or slightly greater than the distance between two adjacent positive sides and / or the distance between two adjacent negative sides, but less than the distance between three adjacent positive sides and / or the distance between three adjacent negative sides.

[0078] More specifically, the sum of the aforementioned actuation amounts is the sum of the actuation amount of the shifting block on the front side and the actuation amount of the locking block on the back side of the locking groove. That is, when the swinging component swings back and forth, the shifting block can sequentially and cyclically actuate the front side of the locking groove and the front side of the unlocking groove, and the locking block can sequentially and cyclically actuate the back side of the locking groove and the back side of the unlocking groove.

[0079] When the travel limit block 644 and the locking block 623 are engaged, the swing locking block 621 on the swing member 62 is stuck in one of the engagement grooves on the first engagement wheel 61, but has not completely disengaged; at this time, the swing member 62 cannot continue to rotate (swing) in the second direction to the maximum amount of swing due to the engagement of the travel limit block 644 and the locking block 623.

[0080] It is worth noting that when there is no travel limit block to stop it, the swinging member can continue to rotate (swing) in the second direction to the maximum swing amount. Therefore, when the locking block engages with the unlocking groove without a travel limit block: under the drive of the first engagement wheel, the swinging member can rotate (swing) in the second direction to the maximum swing amount, causing the swinging lock block to completely disengage from the engagement groove.

[0081] Furthermore, such as Figure 8 , 9 As shown, in the axial direction of the second mating wheel 641, the locking groove 642 is divided into a first-end locking groove and a second-end locking groove, and the stroke limiting block 644 is formed on the bottom wall of the first-end locking groove or on the bottom wall of the second-end locking groove.

[0082] For example, when the travel limit block is formed on the bottom wall of the first end locking groove, the position of the change block is set to cooperate with the second end locking groove, and the locking block is set to cooperate with the first end locking groove, so as to achieve the travel limit block's avoidance setting on the change block and the limiting setting on the locking block.

[0083] The back side of the locking groove 642 is formed with a relief slope 647 that is inclined toward the front side of the adjacent unlocking groove 643. The relief slope 647 can extend to the travel limit block. The travel limit block 644 has an outwardly convex travel supplement arc surface 6441 that engages with the relief slope 647, and an abutment surface 6442 that engages with the outwardly convex travel supplement arc surface 6441. The abutment surface 6442 is used to abut against the locking lever 623.

[0084] The inclined surface 647 and the convex stroke supplementary arc surface 6441 are used to ensure that: the amount of movement of the locking block 623 on the second mating wheel 641 when it is engaged with the locking groove 642 is the same or substantially the same as the amount of movement of the locking block 623 on the second mating wheel 641 when it is engaged with the unlocking groove 643. The amount of movement of the second mating wheel 641 by the locking block 623 each time is the same or substantially the same. This makes it easier to set the shape of the conversion block and the slope of the front side, and also better ensures that the conversion block can stably move different front sides.

[0085] When the swing lock block 621 is engaged in the mating groove 611, and the swing member 62 is rotated in the second direction by the first mating wheel 61, the swing lock block 621 cannot be completely disengaged from the mating groove 611 due to the abutting engagement of the aforementioned travel limit block 644 and the locking lever block 623. As a result, the swing lock block 621 resists the inner wall of the mating groove 611, thereby restricting the first mating wheel 61 and preventing it from continuing to rotate in a certain direction (which should have driven the swing member to rotate in the second direction). However, the first mating wheel 61 is allowed to rotate in the opposite direction. When rotating in the opposite direction, the locking lever block 623 is driven to swing in the direction of disengaging from the locking groove 642.

[0086] Through the aforementioned unidirectional limiting action, the roller 3 is configured to allow the unwinding of the shading material 1 (i.e., the shading material can be pulled out and unfolded), while the roller 3 is restricted from rewinding the shading material 1. Specifically, during shading, after the shading material 1 is pulled out (unwinding), the rotation of the second mating wheel 641 is adjusted so that the travel limit block 644 can abut against the locking block 623, thereby preventing the shading material 1 from automatically retracting due to the influence of the winding elastic element 5, thus achieving automatic locking after being pulled out.

[0087] The second mating wheel 641 can be adjusted by pulling the sunshade roll 1 back and forth, causing the first mating wheel 61 on the roller 3 to drive the swinging member 62, thereby causing the second mating wheel 641 to be moved by the conversion block 622 and the locking block 623.

[0088] When the swing member 62 swings back and forth in a cyclical motion with the maximum excess swing amount, the changeover block 622 and the locking block 623 behave as follows:

[0089] After the switching block moves the S1th positive side, the locking block moves the M1th unlocking groove's negative side, then the switching block moves the S2th positive side, and the locking block moves the N1th locking groove's negative side.

[0090] Then, the switching block moves the S3rd positive side, the locking block moves the M2th unlocking groove's negative side, the switching block moves the S4th positive side, and the locking block moves the N2th locking groove's negative side.

[0091] This cycle continues.

[0092] The S1-Sn front sides are sequentially arranged front sides, including the front side of the unlocking groove and the front side of the locking groove. The M1-Mn back sides of the unlocking grooves are sequentially arranged back sides of the unlocking grooves. The N1-Nn back sides of the locking grooves are sequentially arranged back sides of the locking grooves.

[0093] When the locking lever moves the back side of the Nn-th locking groove, it is set to restrict the sunshade roll from rolling up during normal use, i.e., locking.

[0094] When the locking lever moves the back side of the Mn-th unlocking groove, it is set to allow the sunshade roll to be wound up when it is not in use. When the sunshade roll is allowed to be wound up, the winding elastic element drives the winding roller to be wound up, which unlocks the roll.

[0095] The above-mentioned cycle method can be understood as follows: by switching the toggle to move different positive sides, the user can select the locking toggle to correspond with the locking groove or select the locking toggle to correspond with the unlocking groove, thereby achieving the purpose of automatically winding and automatically locking the winding to limit the winding in conjunction with the winding elastic element.

[0096] The aforementioned self-locking mechanism eliminates the need for separate pin locking. After the shading roll is pulled out and unrolled, it can be locked easily, providing good shading roll unwinding and stopping capabilities. It can stop at multiple points, offering better functionality. Combined with the winding elastic element, pulling out and rewinding are more convenient.

[0097] Furthermore, the support mechanism 4 includes a connecting block 41 mounted on the mounting frame 2, and a folding component 42 is mounted on the connecting block 41. The connecting block 41 is connected to a support member 43 through the folding component 42, and the sunshade roll 1 is connected to the support member 43.

[0098] The sunshade roll 1 can always be connected to the support member 43. When the sunshade roll 1 is pulled out, the support member 43 is pulled out together through the folding component 42. The pulled-out sunshade roll 1 can be supported by the support member 43 and the unfolded folding component 42. When the sunshade roll 1 is rolled up, it can be folded together by the sunshade roll 1 with the reset function, or the sunshade roll 1 and the folding component 42 can be pushed back together manually.

[0099] The shading roll 1 can also be detachably connected to the support member 43. When connection is needed, the shading roll 1 can be attached to the support member 43. For example, a metal ring can be attached to the shading roll, and a corresponding hook can be set on the support member.

[0100] The folding assembly 42 is composed of an even number of support arms 421 that are connected end to end in a sequential rotational manner. The first support arm is rotatably connected to the connecting block, and the last support arm is rotatably connected to the support block.

[0101] Preferably, the connecting block 41 has two blocks respectively close to both ends of the roller 3, and each connecting block 41 is provided with a set of folding components. The last support arm of the two sets of folding components is rotatably connected to both ends of the support member 43.

[0102] During folding, the first support arm rotates and folds in the direction of being inserted between the two connecting blocks, while the last support arm rotates and folds in the direction of being closer to the center of the support.

[0103] Figure 2 As shown, each folding assembly has four support arms, which have a greater extension length, preferably more than 3 meters.

[0104] When the support component 42 supports the sunshade roll 1, the support arm 421 is preferably located below the sunshade roll 1, which has a better support effect and provides rain and sun protection for the folding component.

[0105] A support rod 46 is rotatably connected to the support member 43, which provides further support and improves the support effect. The support rod 46 can be rotated to be retracted and to provide support.

[0106] The support rod 46 is preferably a telescopic rod, which provides support at different heights, allowing the outdoor sunshade device to have different uses, such as serving as a canopy that requires a higher height.

[0107] There may be two support rods 46. When rotating to retract, the two support rods are staggered and will not affect each other's storage position. That is, the support rod 46 has a certain length after being stored and can be used at a certain height without stretching when rotating for support.

[0108] The support member 43 may also have a groove for storing the support rod 46.

[0109] The mounting bracket 2 may have multiple surrounding surfaces to provide the necessary shading and protection for the sunshade roll 1, and to allow for the folding and storage of the support mechanism 4. The mounting bracket 2 may also have a flip cover, which can be opened when in use and closed after use to better protect the self-locking mechanism, support mechanism, sunshade roll and other components.

[0110] Users can install this outdoor sunshade device on vehicles such as RVs and off-road vehicles to provide sufficient height for the mounting frame, allowing the sunshade roll to be used for sun shading when pulled out. It can also be used for rain protection, snow protection, and sun shading. Therefore, the sunshade roll can actually be made of materials such as fabric or plastic film.

[0111] Preferably, a stroke supplement guide rail 44 is formed on the mounting bracket 2, and a slider 45 is slidably mounted on the stroke supplement guide rail 44. The sliding direction of the slider 45 is the same as the stretching direction of the folding component 42, and the connecting block 41 is connected to the slider 45.

[0112] The addition of travel guide rail 44 and slider 45 allows the self-locking mechanism to be unlocked more easily after the folding component 42 is stretched to its maximum extension, thus preventing it from being locked and unable to extend (it needs to be pulled outwards again after locking).

[0113] When used as a mounting bracket 2 to store the folded component 42, the travel supplement guide rail 44 is preferably located within the storage space. The design of the travel supplement guide rail 44 allows the connecting block 41 to move outward a certain distance during use to increase the overall extension. Combined with the support arm, it can build a larger area. When stored, the connecting block 41 can move inward a certain distance to ensure that the folded component is stored as much as possible.

[0114] The winding elastic element 5 is used to ensure that the roller 3 is in a rotating position capable of winding up the sunshade roll 1 after the roll is unwound. The winding elastic element can be configured and structured in various ways, such as using a coil spring or torsion spring. Its position of action can be on the roller, the first mating wheel, or other locations that allow the roller to rotate to wind the sunshade roll. When the first mating wheel is located at one end of the roller, the winding elastic element can act on the other end of the roller.

[0115] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
