Description

Technical Field

[0001] This application relates to the field of sunshade technology, specifically to a canopy structure and a quick-opening sunshade. Background Technology

[0002] Tent products generally consist of a head, support poles hinged to the head, and a curtain laid on the outside of the support poles.

[0003] Based on an understanding of the relevant technologies, some tent products primarily rely on the elastic deformation of the top support poles for support. In strong winds or when the tent is impacted from the outside, the top of the tent is prone to collapse. Furthermore, because the top of the tent needs to be supported by the elastic deformation of the support poles, when the tent is unfolded, a person needs to stand inside the tent and lift the connecting plate in the middle to cause the support poles to deform for support. However, since the connecting plate on the support pole is relatively high, shorter users may not be able to easily reach the connecting plate during operation, making it inconvenient. Utility Model Content

[0004] The purpose of at least one specific embodiment of this utility model is to overcome the defects of the existing technology and provide a canopy structure and a quick-opening sunshade.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A canopy structure includes an upper plate head and a lower plate head, with a support frame connecting the upper plate head and the lower plate head. A support rod passing through the lower plate head is also connected to the upper plate head, and the support rod is provided with an elastic positioning element that cooperates with the lower plate head to restrict the movement of the lower plate head when the canopy is opened.

[0007] The lower pan head includes a pan head body, on which a push-pull component is movably sleeved. The push-pull component has a positioning groove that can cooperate with an elastic positioning component. The lower pan head is provided with a reset component that acts on the push-pull component to reset it.

[0008] With the canopy open, the elastic positioning element is located in the positioning groove. When an external force is applied to the push-pull element and it moves downward relative to the pan head body, the push-pull element can touch the elastic positioning element, causing the elastic positioning element to disengage from the positioning groove. The push-pull element also drives the lower pan head to move downward along the support rod, causing the canopy to close. When the external force disappears, the reset element acts on the push-pull element, causing the push-pull element to reset to its initial position.

[0009] Furthermore, the lower pan head also includes a support base located on the pan head body, and a reset component located between the support base and the push-pull component. One end of the reset component abuts against the support base, and the other end abuts against the push-pull component for support.

[0010] Furthermore, an assembly space is formed between the pan head body and the push-pull component, the reset component is located within the assembly space, and the support base is at least partially located within the assembly space.

[0011] Furthermore, the support base is fitted onto the main body of the pan head.

[0012] Furthermore, one of the support base and the pan head body is provided with a positioning protrusion, and the other of the support base and the pan head body is provided with a positioning hole corresponding to the positioning protrusion. The support base and the pan head body are fixed by the mutually cooperating positioning protrusion and positioning hole.

[0013] Furthermore, the inner wall of the push-pull component has several protruding ribs, each rib having a force-bearing surface that abuts against the reset component, and a positioning groove is formed on one or more of the ribs.

[0014] Furthermore, a guide groove is provided on the pan head body, and at least part of one of the protruding ribs with a positioning groove is located in the guide groove, and the elastic positioning member can extend out of the guide groove and enter the positioning groove.

[0015] Furthermore, the main body of the head is also provided with a limiting groove that coincides with the guide groove.

[0016] Furthermore, a boss protrudes from the lower outer wall of the push-pull component.

[0017] Furthermore, the push-pull component is connected to a downwardly extending extension, the lower end of which is located below the lower plate head, or the lower end of which is 1.7 meters to 2.5 meters from the ground.

[0018] The advantages of the canopy structure provided in this application compared with the prior art are as follows: During the unfolding process, the support frame of this application can drive the pan head body to squeeze the elastic positioning element and move towards the upper pan head until the elastic positioning element is reset. The pan head body is positioned on the support rod and the support frame is kept in the unfolded state. When the support frame is hinged to the upper pan head, it is mainly supported by the positioned pan head body. The support frame is stable when unfolded and will not collapse when subjected to external wind force or impact.

[0019] Moreover, when one end of the support frame is moved, the support frame can be unfolded. The unfolded support frame can assist the pan head body, so that the pan head body can squeeze the elastic positioning component, eliminating the need for the user to lift the pan head with great force, making operation easier.

[0020] The canopy structure of this application is unlocked mainly through a push-pull mechanism. Pulling the push-pull mechanism downwards allows for relative movement between the lower and upper panels. Furthermore, since the push-pull mechanism is pulled downwards, the user can easily retract the canopy, making it convenient for the user to operate.

[0021] In addition, the push-pull component is connected to an extension component, which hangs naturally from the push-pull component to the ground. When users close or close the canopy structure, users of different heights can directly touch the extension component and pull the push-pull component through the extension component to close the canopy, making the operation convenient.

[0022] Another technical solution adopted in this application is to provide a quick-opening sunshade, which includes the above-mentioned canopy structure.

[0023] Because of the aforementioned canopy structure, the quick-opening sunshade has the technical effects of the aforementioned canopy structure. Attached Figure Description

[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 10 A canopy structure 300 includes an upper canopy head 301, a support rod 302 fixedly connected to the upper canopy head 301, and a lower canopy head 310 sleeved on the outside of the support rod 302. The lower canopy head 310 has a canopy head body 303, which is integrally formed with the lower canopy head 310. In addition, an elastic positioning member is installed inside the support rod 302. A support frame 300b is hinged between the upper canopy head 301 and the lower canopy head 310. During the unfolding process, the support frame 300b can drive the lower canopy head 310 to move towards the upper canopy head 301. At the same time, the canopy head body 303 will squeeze the elastic positioning member and move towards the upper canopy head 301 until the elastic positioning member is reset. The canopy head body 303 is positioned on the support rod 302 and the support frame 300b is kept in the unfolded state.

[0040] A push-pull member 305 is sleeved on the outer side of the pan head body 303. When the canopy is open, when an external force is applied to the push-pull member 305 to move downward relative to the pan head body 303, it can squeeze the elastic positioning member, thereby releasing the locking state of the pan head body 303. The push-pull member 305 drives the lower pan head 310 to move downward along the support rod 302 to close the canopy. At this time, the support frame 300b is in the closed state.

[0041] In this embodiment, the canopy structure 300 also includes a support base 304 installed on the pan head body 303 and a reset member 306 sleeved on the outside of the pan head body 303. One end of the reset member 306 abuts against the support base 304, and the other end is connected to the push-pull member 305. When the external force on the push-pull member 305 disappears, the reset member 306 acts on the push-pull member 305 to reset the push-pull member 305 to the initial position.

[0042] Specifically, the reset component 306 can be a compression spring. When the compression spring is installed, one end of it abuts against the support base 304, and the other end is connected to the push-pull component 305. When an external force is applied to the push-pull component 305 and it moves downward relative to the pan head body 303, the compression spring will be compressed. When the external force on the push-pull component 305 disappears, the compression spring resets, so that the push-pull component 305 is reset to the initial position.

[0043] Alternatively, the reset member 306 can also be a rubber band or a tension spring. When the reset member 306 is a rubber band or a tension spring, one end of it is connected to the push-pull member 305, and the other end is connected to the end of the pan head body 303 near the support frame 300b. When an external force is applied to the push-pull member 305 and it moves downward relative to the pan head body 303, the rubber band or tension spring will be stretched. When the external force on the push-pull member 305 disappears, the rubber band or tension spring resets, so that the push-pull member 305 resets to the initial position.

[0044] The canopy structure of this application is unlocked mainly through the push-pull component 305. Pulling the push-pull component 305 downwards allows for relative movement between the lower plate head 310 and the upper plate head 301. Furthermore, since the push-pull component 305 is pulled downwards, the user can easily retract the canopy, making it convenient for the user to operate.

[0045] Furthermore, the elastic positioning element includes an elastic element 307 and positioning elements 308 installed on both sides of the elastic element 307. The elastic element 307 is similar to a leaf spring structure, and the support rod 302 has a through hole 309. Under the elastic force of the elastic element 307, at least part of the positioning element 308 passes through the through hole 309 and is exposed on the outside of the support rod 302.

[0046] It should be noted that the support base 304 provided at one end of the pan head body 303 can support the reset member 306, so that the push-pull member 305 is held in a fixed position on the pan head body 303 by the reset member 306 when no external force is applied, which is convenient for locking when the canopy structure is opened. The position of the support base 304 is not moved by the force acting on the push-pull member 305, thereby ensuring that the reset member 306 can be compressed to leave space for the movement of the push-pull member 305. This structure realizes the support and movement of the push-pull member 305.

[0047] Furthermore, an assembly space with an opening facing the ground is formed between the pan head body 303 and the push-pull member 305. The reset member 306 is located in the assembly space, and the support base 304 is at least partially located in the assembly space. The support base 304 can cover at least part of the opening of the assembly space, which can reduce the gap between the push-pull member 305 and the pan head body 303, reduce the intrusion of dust and sand, reduce the occurrence of failures, and improve service life.

[0048] In addition, in this embodiment, the support base 304 is sleeved on the pan head body 303. Of course, the support base 304 can be integrally set with the pan head body 303 or it can be set by connection. When it is integrally set, the reset member 306 will interfere with the support base 304 during the assembly process, and sufficient assembly space needs to be reserved on the push-pull member 305, resulting in a large gap after assembly and an uncompacted structure. Furthermore, when the reset member 306 is used in this embodiment, in order to facilitate smooth assembly, the area of ​​action of the reset member 306 on the push-pull member 305 is small, which easily leads to the push-pull member 305 not being able to effectively act on the reset member 306 when it moves under the action of external force, resulting in slippage.

[0049] The support base 304 is sleeved and connected to the pan head body 303, which facilitates the assembly of the reset component 306. Specifically, in this embodiment, the support base 304 is assembled after the reset component 306 is assembled. Therefore, the reset component 306 will not interfere with the support base 304 during assembly, and the compactness after assembly is better. Because the reset component 306 does not need to consider the interference between it and the support base 304 during assembly, it can ensure that an effective contact area is provided for the reset component 306, thereby preventing the push-pull component 305 from falling off due to the small force-bearing area when it acts on the reset component 306.

[0050] Reference Figure 4 , Figure 5 , Figure 10 , Figure 11 One of the support base 304 and the pan head body 303 is provided with a positioning protrusion 303b, and the other of the support base 304 and the pan head body 303 is provided with a positioning hole 304a corresponding to the positioning protrusion 303b. The support base 304 and the pan head body 303 are fixed by the mutually cooperating positioning protrusion 303b and positioning hole 304a.

[0051] Furthermore, the pan head body 303 has a guide groove 315 on its circumferential surface, which extends along the height direction of the pan head body 303. The inner wall of the support base 304 is provided with a guide positioning protrusion 304b. When the support base 304 and the pan head body 303 are assembled together, the support base 304 is fitted onto the pan head body 303, and the guide positioning protrusion 304b on the inner wall of the support base 304 will slide into the guide groove 315. During the sliding process, the guide positioning protrusion 304b will squeeze the inner wall of the guide groove 315, causing the pan head body 303 to expand radially. The two positioning protrusions 303b on the outer wall of the radially expanded pan head body 303 will engage with the positioning holes 304a on the support base 304, thereby achieving the fixed installation of the support base 304.

[0052] Additionally, refer to Figure 3 , Figure 6The inner wall of the push-pull member 305 is provided with a plurality of annularly arranged ribs. Some of the ribs can be constructed as support bosses 305a, and other parts or at least one of the ribs can be constructed as guide parts 314. The reset member 306 is sleeved on the outside of the pan head body 303, with one end abutting against the side of the support seat 304 and the other end abutting against the side of the support boss 305a.

[0053] When the push-pull member 305 is subjected to tension, it compresses the reset member 306 and squeezes the elastic positioning member. The elastic positioning member is squeezed back into the support rod. The push-pull member 305 is subjected to downward tension, which is transmitted to the support seat. As the downward tension continues, it eventually drives the pan head body 303 to move away from the upper pan head 301. When the tension on the push-pull member 305 disappears, the reset member 306 drives the push-pull member 305 to reset on the outside of the pan head body 303.

[0054] Furthermore, multiple connecting rods 311 are hinged to the upper plate head 301, and a diagonal rod 312 is hinged to the lower plate head 310. The end of the diagonal rod 312 away from the lower plate head 310 is hinged to the connecting rods 311. The connecting rods 311 and the diagonal rod 312 that are hinged to each other constitute the support frame 300b.

[0055] In this embodiment, the pan head body 303 is provided with a limiting groove 303a that overlaps with the guide groove 315. When the support frame is unfolded, the support frame 300b drives the pan head body 303 and the lower pan head 310 to move toward the upper pan head 301 by the tension generated during the unfolding process, and squeezes the positioning member 308 until the through hole 309 and the limiting groove 303a are aligned. The elastic positioning member passes through at least part of the through hole 309 and the limiting groove 303a, so that the pan head body 303 is locked on the support rod 302.

[0056] When the support frame 300b needs to be retracted, the push-pull component 305 is pulled, causing the push-pull component 305 to press against the positioning component 308. When the positioning component 308 is pressed, it separates from the limiting groove 303a, and the locking state of the pan head body 303 on the support rod 302 is released. The thrust generated during the retraction of the support frame pushes the pan head body 303 and the lower pan head 310 to move away from the upper pan head 301.

[0057] Additionally, refer to Figure 3 , Figure 10 The inner wall of the pan head body 303 has a pressing part 313, and the inner wall of the push-pull member 305 has a guide part 314. Since the pan head body 303 has a guide groove 315 on its circumferential surface, one side of the guide part 314 extends into the guide groove 315. When the push-pull member 305 slides on the outside of the pan head body 303, the guide groove 315 can circumferentially limit the push-pull member 305 through sliding cooperation with the guide part 314, so as to prevent the push-pull member 305 from circumferentially rotating during the sliding process on the outside of the pan head body 303.

[0058] In this embodiment, the extrusion part 313 has a first extrusion slope 313a, and the guide part 314 has a second extrusion slope 314a. The first extrusion slope 313a and the second extrusion slope 314a extend in opposite directions.

[0059] Furthermore, the push-pull component 305 is provided with an outwardly protruding pull-down boss 316, and an extension component 317 is connected to the pull-down boss 316. The extension component 317 is preferably a pull rope, and the lower end of the extension component 317 is located below the lower plate head 310. Preferably, the lower end of the extension component 317 is 1.7 meters to 2.5 meters above the ground. When the canopy structure 300 is closed, it is convenient for a person's palm to touch the extension component 317, thereby pulling the push-pull component 305 and making the canopy structure 300 close smoothly. The lower end of the extension component 317 is 1.7 meters, 1.9 meters, 2 meters, or 2.5 meters above the ground. A ground clearance of 2 meters is preferred. In addition, this embodiment lists the ground clearance range and provides a preferred implementation method, wherein the extension component 317 can be replaced to achieve the above-mentioned ground clearance range, or the above-mentioned ground clearance can be achieved by adjusting the relative connection position of the extension component 317 and the push-pull component 305.

[0060] Additionally, it should be noted that the pull-down boss 316 is arranged circumferentially around the push-pull member 305, which allows the user to easily apply force when pulling the push-pull member 305.

[0061] The locking and unlocking process of the support rod 302 and the pan head body 303 in this embodiment will be described in detail below, taking into account the folding process of the canopy structure 300.

[0062] Reference Figure 3 , Figure 8 , Figure 9 When the entire canopy structure 300 changes from a retracted state to an extended state, the connecting rod 311 is rotated outward by hand. During the rotation, the connecting rod 311 pulls the pan head body 303 through the inclined rod 312, causing the pan head body 303 to slide towards the upper pan head 301. When the pressing part 313 on the inner wall of the pan head body 303 approaches the head of the positioning member 308, the first pressing inclined surface 313a will press the positioning member 308. After being pressed, the positioning member 308 will retract into the interior of the support rod 302. At this time, the pan head body 303 will continue to sweep across the surface of the positioning member 308 until the limiting groove 303a on the wall of the pan head body 303 corresponds to the positioning member 308. Under the elastic force of the elastic member 307, the positioning member 308 extends into the limiting groove 303a. At this time, the pan head body 303 and the support rod 302 are locked, and the connecting rod 311 hinged on the upper pan head 301 is in a fully open state.

[0063] Similarly, when the entire canopy structure 300 changes from the unfolded state to the retracted state, the extension 317 needs to be pulled by hand. The extension 317 generates a downward pulling force on the push-pull member 305. Under the action of the pulling force, the guide part 314 on the inner wall of the push-pull member 305 approaches the positioning member 308. Until the second extrusion slope 314a gradually extrudes the head of the positioning member 308, the positioning member 308 will retract from the limiting groove 303a into the support rod 302. At this time, the locking state between the pan head body 303 and the support rod 302 is released, and the hand can release the lock. After the extension 317 is opened, the reset component 306 drives the push-pull component 305 to reset. At the same time, when the connecting rod 311 on the upper pan head 301 is rotated inward by hand, the connecting rod 311 pushes the pan head body 303 through the inclined rod 312 during the rotation, so that the pan head body 303 slides away from the upper pan head 301 until the inner wall of the pan head body 303 completely passes the positioning component 308. At this time, the positioning component 308 will pop out from the support rod 302. At this time, the connecting rod 311 hinged on the upper pan head 301 is in a fully retracted state.

[0064] In this embodiment, the first extrusion slope 313a on the extrusion part 313 extends in the opposite direction to the second extrusion slope 314a on the guide part 314. Whether it is the pan head body 303 or the push-pull member 305 sliding, they can extrude the positioning member 308. The locking and unlocking process of the support rod 302 and the pan head body 303 is relatively convenient and stable.

[0065] Moreover, when the locking state between the pan head body 303 and the support rod 302 needs to be released, the extension part 317 can be pulled by hand, making the operation direct and convenient.

[0066] Example 2

[0067] Reference Figure 7The difference between this embodiment and Embodiment 1 is that the push-pull member 305 has a positioning groove 305b that can cooperate with the elastic positioning member. Specifically, the positioning groove 305b can be formed on the guide portion 314 on the inner wall of the push-pull member 305. The second extrusion slope 314a is the inner wall surface of the positioning groove 305b. The positioning groove 305b mainly serves to limit the end of the positioning member 308. When the canopy structure 300 is in the open state, the cooperating positioning groove 305b and positioning member 308 keep the push-pull member 305 in a locked state. If the push-pull member 305 is not touched, the second extrusion slope 314a will not extrude the end of the positioning member 308. In this embodiment... There is no need to open a limiting groove 303a on the pan head body 303. When the width of the guide groove 315 on the pan head body 303 is wide enough, when the canopy is open, the end of the positioning member 308 can pass through the guide groove 315 and be located in the positioning groove 305b. When an external force is applied to the push-pull member 305 to move downward relative to the pan head body 303, the second extrusion inclined surface 314a can touch and extrude the positioning member 308, causing the positioning member 308 to disengage from the positioning groove 305b. The push-pull member 305 drives the lower pan head 310 to move downward along the support rod 302 to close the canopy. When the external force disappears, the reset member 306 acts on the push-pull member 305 to reset the push-pull member 305 to the initial position.

[0068] Example 3

[0069] Reference Figure 12 , Figure 13 A quick-opening sunshade 400 includes the canopy structure 300 described in Embodiment 1 or Embodiment 2. The connecting rod 311 of the canopy structure 300 is configured as the tent pole of the quick-opening sunshade. The end of the connecting rod 311 away from the upper head 301 is hinged to a first tent pole 401. The first tent pole 401 is hinged to a second tent pole 402, and the second tent pole 402 is hinged to a third tent pole 403. When the sunshade 400 needs to be opened, a person holds the free end of the third tent pole 403 and flicks it away from the upper head 301. At this time, relative rotation occurs between the connecting rod 311, the first tent pole 401, the second tent pole 402, and the third tent pole 403 until the free end of the third tent pole 403 rotates to face 500 degrees towards the ground. The connecting rod 311, the first tent pole 401, the second tent pole 402, and the third tent pole 403 are all in an extended state. During the extension process, the connecting rod 311 pulls the head body 303 of the canopy structure 300 through the diagonal rod 312, so that the head body 303 and the lower head 310 slide towards the upper head 301 and lock. The locking process of the head body 303 is as described in the above embodiment. After the head body 303 is locked, the connecting rods 311, the first tent pole 401, the second tent pole 402, and the third tent pole 403 will maintain a stable connection state. The overall structure will not collapse regardless of wind or impact. The entire sunshade 400 structure is stable after extension.

[0070] When the quick-opening sunshade is closed, the locking state of the canopy structure 300 can be released by pulling the extension 317 (the specific unlocking process is as described in the above embodiment). At this time, the third tent pole 403 is held by hand and pushed towards the upward head 301, and the connecting rod 311, the first tent pole 401, the second tent pole 402 and the third tent pole 403 can be closed smoothly. Since the extension 317 extends from the top of the quick-opening sunshade to the ground, it is easy to touch by hand, and the operation is direct and convenient.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
