An automatic opening sunshade Related applications

[0001] This application claims priority to Chinese Patent No. CN2024226701473, filed on November 4, 2024. Technical Field

[0002] This disclosure relates to the field of sunshade technology, specifically to an automatically opening sunshade. Background Technology

[0003] Existing sun umbrellas are often quite large in order to provide better sun and rain protection. However, due to their large frames or tall handles, these sun umbrellas are time-consuming and laborious to open. How to design a sun umbrella that is easy to operate and open has always been a goal pursued by those skilled in the art. Summary of the Invention

[0004] The technical problem to be solved by this disclosure is to overcome the shortcomings of the prior art and provide a novel automatic opening sunshade.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this disclosure is as follows:

[0006] An automatically opening sunshade, having an open state and a closed state, includes:

[0007] umbrella pole;

[0008] A sliding component, which is slidably disposed on the umbrella pole along the length extension direction of the umbrella pole;

[0009] An umbrella frame is provided on the upper part of the umbrella pole. The umbrella frame includes multiple top rod assemblies. Each top rod assembly includes a first top rod and a second top rod disposed below the first top rod. The first top rod and the second top rod both have inner ends and outer ends. The inner ends of the first top rod and the second top rod are respectively rotatably connected to the umbrella pole. Each top rod assembly is provided with at least one connecting rod located between the first top rod and the second top rod. The connecting rod is rotatably connected to the first top rod and the second top rod respectively.

[0010] At least one elastic element is provided in each of the push rod assemblies, located between the first push rod and the second push rod, and the elastic element is connected to the first push rod and the second push rod respectively;

[0011] A support rod, one end of which is rotatably connected to the second top rod, and the other end of which is rotatably connected to the sliding assembly;

[0012] When in the unfolded state, the umbrella frame is unfolded relative to the umbrella pole, the elastic element is in a natural state, and the length extension direction of the elastic element is not parallel to the length extension direction of the connecting rod. When in the retracted state, the umbrella frame is retracted relative to the umbrella pole, the elastic element is in a deformed state, accumulating elastic force. When transitioning from the retracted state to the unfolded state, the elastic element provides the elastic force required for the sliding assembly to slide from bottom to top along the umbrella pole.

[0013] In one embodiment, the sliding component can be locked and unlocked relative to the umbrella pole. When in the unfolded state, the sliding component is locked relative to the umbrella pole; when in the folded state, the sliding component is locked relative to the umbrella pole; and when transitioning from the folded state to the unfolded state, the sliding component is unlocked relative to the umbrella pole.

[0014] In one embodiment, the elastic element is a tension spring. When in the extended state, the elastic element contracts, and the connection point between the elastic element and the second push rod is located outside the connection point between the elastic element and the first push rod. When in the retracted state, the elastic element extends.

[0015] In one embodiment, the elastic element is a compression spring. When in the unfolded state, the elastic element extends, and the connection point between the elastic element and the second push rod is located inside the connection point between the elastic element and the first push rod. When in the retracted state, the elastic element contracts.

[0016] In one embodiment, the connecting rod includes a first connecting rod, which is rotatably connected to the outer ends of the first push rod and the second push rod, respectively.

[0017] In one embodiment, the connecting rod includes a second connecting rod, which is rotatably connected to the middle portions of the first push rod and the second push rod, respectively.

[0018] In one embodiment, the length extension directions of the first connecting rod and the second connecting rod are parallel. In another embodiment, the length extension directions of the first push rod and the second push rod are parallel.

[0019] In one embodiment, the umbrella pole is provided with a locking groove, and the sliding assembly includes a locking member and an unlocking member for controlling the locking member to disengage from the locking groove.

[0020] In one embodiment, in each of the push rod assemblies, the elastic element is configured as at least two symmetrically arranged elements, the first push rod and the second push rod are respectively provided with a hook pin, the hook pin is provided to protrude from the first push rod and the second push rod, and the two ends of the elastic element are respectively rotatably connected to the portion of the hook pin protruding from the first push rod or the second push rod.

[0021] In one embodiment, in each of the top rod assemblies, the first top rod and the second top rod are hollow, and each of the first top rod and the second top rod is provided with a hook pin. The two ends of the elastic member are respectively rotatably connected to the hook pin, and the hook pin and the elastic member are hooked at the position in the first top rod and the second top rod.

[0022] Due to the application of the above technical solution, this disclosure has the following advantages compared with the prior art:

[0023] The automatically opening sunshade disclosed herein includes a first top rod, a connecting rod, a second top rod, and an elastic element. In the unfolded state, by setting the extension direction of the elastic element to be non-parallel to the extension direction of the connecting rod, the elastic element can deform and accumulate elastic force when transitioning from the unfolded state to the retracted state. This provides elastic force for the automatic opening of the sunshade when transitioning from the retracted state to the unfolded state, facilitating the opening of the entire sunshade. Furthermore, the automatically opening sunshade of this disclosure has a simple overall structure, requires little effort to operate, and is easy to operate with one hand.

Detailed Implementation

[0031] The preferred embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this disclosure can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding of this disclosure, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0032] Referring to Figures 1-5, the automatically opening sunshade of this disclosure has an open state and a closed state, and includes: an umbrella pole 1, a sliding assembly 2, an umbrella frame, an elastic element 35, and a support rod 4.

[0033] The sliding component 2 is slidably mounted on the umbrella pole 1 along its length and can be locked and unlocked relative to the umbrella pole 1. Specifically, in some embodiments, the umbrella pole 1 is provided with a locking groove. The sliding component 2 includes a sliding sleeve 21, a locking member (not shown in the figure), and an unlocking member 22 for controlling the locking member to disengage from the locking groove. The locking member is disengaged from the locking groove by operating the unlocking member 22, thus unlocking the sliding component 2 relative to the umbrella pole 1. The specific cooperation method between the unlocking member 22 and the locking member can utilize existing technology and will not be elaborated further here.

[0034] In some embodiments, the locking groove includes an upper locking groove 11 for locking the automatically opening sunshade in an unfolded state and a lower locking groove 12 for locking the automatically opening sunshade in a closed state. The upper locking groove 11 has an upper inclined surface 111 that allows the locking member to slide upward relative to the locking groove and a lower blocking surface 112 that prevents the locking member from sliding downward relative to the locking groove, as shown in FIG3. Multiple upper locking grooves 11 are provided, so that the sunshade has multiple unfolded positions in the unfolded state. The upper inclined surface 11 extends obliquely from the inside to the outside from bottom to top, and the lower blocking surface 112 extends generally in the horizontal direction. The lower locking groove 12 has a lower inclined surface 121 that allows the locking member to slide downward relative to the locking groove and an upper blocking surface 122 that prevents the locking member from sliding upward relative to the locking groove, as shown in FIG3. Multiple lower locking grooves 12 are provided, so that the sunshade has multiple closed positions in the closed state. The lower inclined surface 121 extends obliquely from the inside to the outside from top to bottom, and the upper blocking surface 122 extends generally in the horizontal direction. In one embodiment, a limiting member 13 can be provided at the upper end of the upper locking groove 12 to prevent the sliding component 2 from sliding further upward and to prevent damage.

[0035] The umbrella frame is located on the upper part of the umbrella pole 1. The umbrella frame includes multiple top rod assemblies 3, as shown in Figure 1. In this embodiment, four top rod assemblies 3 are provided, as shown in Figure 5. Alternatively, six top rod assemblies 3 can be provided, and in some embodiments, other numbers of top rod assemblies 3 can also be provided. Each top rod assembly 3 includes a first top rod 31 and a second top rod 32 disposed below the first top rod 31. The length extension direction of the first top rod 31 and the length extension direction of the second top rod 32 are parallel. Both the first top rod 31 and the second top rod 32 have inner ends and outer ends. The inner ends of the first top rod 31 and the second top rod 32 are rotatably connected to the umbrella pole 1, respectively. In one embodiment, the umbrella pole 1 includes an upper umbrella seat 14 and a lower umbrella seat 15. The inner end of the first top rod 31 is rotatably connected to the upper umbrella seat 14, and the inner end of the second top rod 32 is rotatably connected to the lower umbrella seat 15.

[0036] Each push rod assembly 3 includes at least one connecting rod located between the first push rod 31 and the second push rod 32. The connecting rod is rotatably connected to the first push rod 31 and the second push rod 32, respectively. In some embodiments, the connecting rod includes a first connecting rod 33 and a second connecting rod 34. The first connecting rod 33 is rotatably connected to the outer ends of the first push rod 31 and the second push rod 32, respectively. The second connecting rod 34 is rotatably connected to the middle portion of the first push rod 31 and the middle portion of the second push rod 32, respectively. The length extension direction of the first connecting rod 33 and the length extension direction of the second connecting rod 34 are parallel. In other embodiments, each push rod assembly 3 may also include only the first connecting rod 33 or the second connecting rod 34.

[0037] Each push rod assembly 3 is provided with at least one elastic element 35 located between the first push rod 31 and the second push rod 32. The elastic element 35 is connected to the first push rod 31 and the second push rod 32 respectively. In some embodiments, the elastic element 35 is a tension spring, as shown in Figures 1-5. The elastic element 35 in each push rod assembly 3 can be provided as two symmetrically distributed ones to make the elastic force in each push rod assembly 3 more uniform. The first push rod 31 and the second push rod 32 are respectively provided with hook pins. The hook pins are provided to protrude from the first push rod and the second push rod to facilitate hooking the elastic element 35. The two ends of the elastic element 35 are rotatably connected to the hook pins respectively. In other embodiments, several sets of symmetrically distributed elastic elements 35 can also be provided in the inner and outer directions in each push rod assembly 3. As shown in Figure 5, in each push rod assembly 3, the first push rod 31 and the second push rod 32 are hollow and each has a hook pin inside. The two ends of the elastic element 35 are rotatably connected to the hook pin. At this time, the hook pin and the elastic element 35 are hooked in the first push rod 31 and the second push rod 32. Since the elastic force on the first push rod 31 and the second push rod 32 is relatively uniform, it is not necessary to symmetrically set two elastic elements. In this embodiment, two elastic elements are set in the inner and outer directions respectively. In other embodiments, each push rod assembly may only have one elastic element.

[0038] One end of the support rod 4 is rotatably connected to the second top rod 32, and the other end of the support rod 4 is rotatably connected to the sliding assembly 2. Specifically, the other end of the support rod 4 is rotatably connected to the sliding seat 27 on the top of the sliding assembly 2. The number of support rods 4 corresponds to the number of top rod assemblies 2. As shown in Figures 1-4, there are 4 support rods 4; as shown in Figure 5, there are 6 support rods 4. In some embodiments, the rotatable connection points of the support rod 4 and the second top rod 32, and the rotatable connection points of the second connecting rod 34 and the second top rod 32 are arranged on the same axis. In some embodiments, the rotatable connection points of the elastic element 35 and the second top rod 32, and the rotatable connection points of the second connecting rod 34 and the second top rod 32 can also be arranged on the same axis. In some embodiments, the rotatable connection points of the elastic element 35 and the second top rod 32, and the rotatable connection points of the first connecting rod 33 and the second top rod 32 can also be arranged on the same axis.

[0039] As shown in Figures 1-2 and 5, when in the unfolded state, the umbrella frame unfolds relative to the umbrella pole 1. At this time, the locking member is located in the upper locking groove 11, and the sliding component 2 is locked relative to the umbrella pole 1. The upper locking groove 11 prevents the sliding component 2 from sliding downward, but the user can push the sliding component 2 upward to adjust the unfolded position. The elastic member 35 is in the natural state and the elastic member 35 is contracted. The connection point between the elastic member 35 and the second top rod 32 is located outside the connection point between the elastic member 35 and the first top rod 31. That is, the elastic member 35 extends obliquely from the outside to the inside and from the bottom to the top. The length extension direction of the elastic member 35 is not parallel to the length extension direction of the connecting rod. Specifically, the upper end face of the elastic member 35 forms a first included angle C with the connecting rod. The first included angle C is greater than 0 degrees and less than 90 degrees.

[0040] As shown in Figure 4, when in the folded state, the umbrella frame is folded relative to the umbrella pole 1, the locking member is located in the lower locking groove 12, the sliding component 2 is locked relative to the umbrella pole 1, the lower locking groove 12 prevents the sliding component 2 from sliding upward, but the user can push the sliding component 2 downward to adjust the folded position. The elastic member 35 is in a deformed state, accumulating elastic force. Specifically, the elastic member 35 stretches.

[0041] When switching from the folded state to the unfolded state, the user can operate the pressing part 233 to unlock the sliding component 2 relative to the umbrella pole 1. The elastic element 35 pulls the umbrella frame to open relative to the umbrella pole 1, providing the elastic force required for the sliding component 2 to slide from bottom to top along the umbrella pole 1, thereby automatically opening the sun umbrella. When the sliding component 2 moves to the locking member near the upper locking groove 11, the user can further push the sliding component 2 upward to complete the locking of the sliding component 2 relative to the umbrella pole 1.

[0042] When switching from the unfolded state to the folded state, the user can press the pressing part 233 to unlock the sliding component 2 relative to the umbrella pole 1. Due to gravity, the user only needs to gently pull down the sliding component 2, and the umbrella frame will fold relative to the umbrella pole 1. The user does not need to press the unlocking part 23, but only needs to pull down the sliding component 2 until it engages with the lower locking groove 12 to lock the sliding component 2 relative to the umbrella pole 1.

[0043] In other embodiments, the elastic element 35 can also be a compression spring (not shown in the figure). When the elastic element 35 is set as a compression spring, the main difference between it and the elastic element 35 being set as a tension spring is that when it is in the unfolded state, the elastic element 35 extends, and the connection point between the elastic element 35 and the second push rod 32 is located inside the connection point between the elastic element and the first push rod 31. That is, the compression spring extends obliquely from the inside to the outside and from the bottom to the top, and the length extension direction of the elastic element 35 is not parallel to the length extension direction of the connecting rod. Specifically, the lower end face of the elastic element 35 forms a second included angle with the connecting rod (not shown in the figure). The second included angle is greater than 0 degrees and less than 90 degrees. When it is in the retracted state, the elastic element contracts. When it transitions from the retracted state to the unfolded state, the compression spring releases the elastic force, pushing the umbrella frame to unfold relative to the umbrella rod 1.

[0044] In the description of this disclosure, the directions such as "front," "back," "left," "right," "up," and "down" are defined with reference to the direction observed by the user when using the automatic sunshade, as shown in Figure 2. The left side of the figure is "left," the right side is "right," the upper side is "up," and the lower side is "down." The directions perpendicular to the viewing angle in the figure are "front" and "back." The inward-outward direction refers to the direction extending from near the umbrella pole to away from the umbrella pole. The above definitions of directions are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0045] The above embodiments are only for illustrating the technical concept and features of this disclosure, and are intended to enable those skilled in the art to understand the content of this disclosure and implement it accordingly. They should not be construed as limiting the scope of protection of this disclosure. All equivalent changes or modifications made in accordance with the spirit and essence of this disclosure should be included within the scope of protection of this disclosure.
