Description

Technical Field

[0001] This invention relates to the technical field of awnings, specifically to a modular frame system and assembly method for awnings. Background Technology

[0002] Awnings come in many varieties, but they typically consist of a frame and a canopy. The canopy can be made of canvas, plastic louvers, aluminum alloy louvers, and so on. The frame can also be made of wood, aluminum alloy, steel, and so on. The frame acts as a support, supporting the canopy and creating a space that shelters from wind, rain, and sunlight.

[0003] Aluminum alloy louvered awnings are widely used as a type of outdoor sunshade product. Patent documents such as CN216110040U and CN202559576U disclose this type of awning.

[0004] Authorization announcement numbers CN218061637U, CN217232912U, and CN217269118U disclose a new type of splicing aluminum alloy gazebo. The gazebo body includes at least four supporting columns. Each supporting column has at least two or more separate splicing structures. An aluminum alloy column sleeve is provided between each supporting column segment. The supporting columns are made of aluminum alloy. Multiple column sleeve limiting grooves are provided on the inner surface of the aluminum alloy column. Multiple column sleeve limiting protrusions are provided on the outer surface of the column sleeve, corresponding to the positions of the column sleeve limiting grooves. The column sleeve is installed between the inner cavities of adjacent supporting columns of aluminum alloy. The column sleeve limiting grooves and column sleeve limiting protrusions are fitted together. Each aluminum alloy frame beam and aluminum alloy support segment beam consists of at least two interconnected split-type splicing structures. An embedded aluminum alloy crossbeam core is set between the split-type splicing structures of adjacent segments. The outer surface of the aluminum alloy crossbeam core is tightly fitted with the inner surface of the aluminum alloy frame beam of the splicing segment and fastened with screws.

[0005] However, due to deviations in processing precision, coupled with the fact that aluminum alloys are prone to deformation, it is difficult to complete the insertion of the core and aluminum alloy frame beams or support columns, which are designed to be tightly fitted. Summary of the Invention

[0119] Compared with the prior art, the advantages of the present invention are:

[0120] First: The multi-segment, modular, splicing structure of the side beams and center beams solves the problem of awning size limitations caused by transportation, making the transportation of awnings more convenient and facilitating the construction of large-sized awnings.

[0121] Second: The transverse slots of the beam system not only provide interlocking elements but also save materials and reduce manufacturing costs. In addition, they can reduce the weight of the system, which is more conducive to the construction of awnings and the transportation of bulk awnings.

[0122] Third: The tensioning connection method of the two separate connecting parts also reinforces and supports the splice. By using threaded fastening pins to open the two adjustable connecting parts axially, tensioning them is achieved. This reduces the dimensional accuracy requirements of individual components, adapts to different beam structures, and improves the versatility of beam connection components. Furthermore, compared to conventional non-adjustable interference fits, the adjustable spacing of the two connecting parts makes the splicing and assembly of the beam system easier and faster, reducing the likelihood of insertion difficulties.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

Therefore, they should not be construed as limitations on this invention.

[0139] like Figure 1-2 As shown, this embodiment provides a sunshade awning, which includes a frame system 100 and an awning system 200. The frame system 100 includes a beam system 101 and a column system 102.

[0140] like Figure 2 As shown, the beam system 101 includes several outer edge beams 10 and inner middle beams 20, and the column system 102 includes several columns 30 of equal length. The edge beams 10 are connected end to end to form a frame, and the middle beams 20 span between opposite edge beams 10; the upper ends of the columns 30 are connected to the frame to form a three-dimensional space L below the spliced ​​beam system 101.

[0141] like Figure 3 As shown, the canopy system 200 is mounted on the frame of the beam system 101. It includes louvers 40 located within the area formed by the side beams 10 and the middle beam 20, and push rods 50 that connect the louvers 40 in the same area to drive them to open and close synchronously. The louvers 40 and push rods 50 are rotatably connected via louver connectors Z. The push rods 50 employ a multi-segment, modular structure. Each push rod 50 includes several sub-rods 51, which are connected by push rod connecting pieces 52, facilitating the transport of bulk awnings.

[0142] This embodiment provides a spliced ​​beam system 101 and a spliced ​​column system 102 to form a spliced ​​frame system 100. The side beams 10 in the spliced ​​beam system 101 are multi-segment split spliced ​​structures, or the middle beams 20 can be multi-segment split spliced ​​structures.

[0143] The following uses the edge beam 10 as an example to illustrate the spliced ​​beam system 101 with a multi-segment split splicing structure. The multi-segment split splicing structure of the middle beam 20 is the same as that of the edge beam 10.

[0144] like Figure 4-5As shown, each side beam 10 includes several sub-beams 11, beam connection components 12, and fastening components 13. The splicing ends of adjacent sub-beams 11 are respectively provided with transverse slots M extending in the length direction. Preferably, the sub-beams of the side beams 10 and the middle beam 20 are all made of aluminum profiles, manufactured by extrusion molding. Therefore, the transverse slots M are through grooves extending along the length direction of the sub-beams 11. This not only provides transverse slots M for splicing but also saves materials, reduces the manufacturing cost of the beam system 101, and reduces the weight of the beam system 101, making it more convenient for the erection of the awning and the transportation of bulk awnings.

[0145] like Figure 5-6 As shown, each beam connection assembly 12 includes a first connector 1 and a second connector 2 disposed opposite to each other; the first connector 1 and the second connector 2 form an integral insert that extends in the same direction as the transverse slot M, and the two ends of the beam connection assembly 12 are respectively inserted into the transverse slot M of the adjacent sub-beam 11. The fastening assembly 13 is used to connect the beam connection assembly 12 to the adjacent sub-beam 11 to complete the fastening splicing structure.

[0146] like Figure 5-9 As shown, the fastening assembly 13 includes two threaded fastening pins 3, each threaded fastening pin 3 passing through the corresponding sub-beam 11 and connecting beam connection assembly 12; the threaded fastening pins 3 are used to move the first connecting piece 1 and the second connecting piece 2 away from each other along the axial direction of the threaded fastening pins 3, so that the groove wall of the sub-beam 11 is tightened by the beam connection assembly 12, thereby enabling adjacent sub-beams 11 to be spliced ​​through the beam connection assembly 12.

[0147] like Figure 6-8 As shown, specifically, the transverse slot M of the sub-beam 11 includes a first slot wall e and a second slot wall f. The first slot wall e is provided with a mounting through hole k through which the threaded fastening pin 3 can pass; the two sides of the first connector 1 are provided with threaded through holes p that match the threaded fastening pin 3; the mounting through holes and the threaded through holes form a screwing channel. The threaded fastening pin moves toward the second connector by passing through the screwing channel at the corresponding end. When the end of the threaded fastening pin abuts against the second connector, the threaded fastening pin is screwed, and the threaded through hole interacts with the threaded fastening pin, converting the circular motion of rotation into linear motion, so that the first connector and the second connector move away from each other along the axial direction of the threaded fastening pin; the first connector abuts against the inner side of the first slot wall of the sub-beam, and the second connector abuts against the inner side of the second slot wall of the sub-beam, thereby causing the sub-beam to be tightened by the beam connecting assembly.

[0148] The advantages of this splicing method are that, in addition to connecting adjacent beams 11 along their length, the tensioning connection also reinforces and supports the splice joint. By using threaded fastening pins 3 to open the two adjustable connecting parts axially, tensioning them is achieved, reducing the dimensional accuracy requirements of each component and adapting to beams 11 of different specifications, thus improving the versatility of the beam connection assembly 12. Furthermore, compared to conventional non-adjustable interference fits, the adjustable spacing of the two connecting parts makes the splicing and assembly of the beam system 101 easier and faster, reducing the likelihood of insertion difficulties.

[0149] like Figure 6-8 As shown, the second connector 2 has blind holes q on both sides for inserting threaded fastening pins 3. The so-called blind hole q refers to a blind hole structure with no threads on its inner wall. The mounting through hole k, the threaded through hole p, and the blind hole q are aligned coaxially along a straight line to form a screwing channel.

[0150] When both ends of the beam connecting assembly 12 are respectively inserted into the transverse slots M of the adjacent sub-beams 11, the first mounting through hole k1 of the first sub-beam 11a and the first threaded through hole p1 and the first blind hole q1 of the first end of the beam connecting assembly 12 are coaxially aligned to form a first screwing channel between the first sub-beam 11a and the beam connecting assembly 12; the second mounting through hole k2 of the second sub-beam 11b and the second threaded through hole p2 and the second blind hole q2 of the second end of the beam connecting assembly 12 are coaxially aligned to form a second screwing channel between the second sub-beam 11b and the beam connecting assembly 12. The blind hole q can prevent the threaded fastening pin 3 from slipping against the second connecting piece 2, thereby further enhancing the connection effect.

[0151] The two threaded fastening pins 3 are inserted into the corresponding screwing channels from the outside of the sub-beam 11. The first threaded fastening pin 3a is inserted into the first screwing channel on the side of the first sub-beam 11a, and the second threaded fastening pin 3b is inserted into the second screwing channel on the side of the second sub-beam 11b.

[0152] When the threaded fastening pin 3 is inserted into the blind hole q of the second connector 2 and its end abuts against the bottom of the corresponding blind hole q, the threaded fastening pin 3 is continued to be tightened. Due to the action of the external thread of the threaded fastening pin 3 and the internal thread of the threaded through hole p of the first connector 1, the first connector 1 moves away from the second connector 2 along the threaded fastening pin 3, thereby adjusting the distance between the first connector 1 and the second connector 2. Finally, the first connector 1 is pressed against the inner side of the first groove wall e of the sub-beam 11, and the second connector 2 is pressed against the inner side of the second groove wall f of the sub-beam 11. This is the limit position of the threaded fastening pin 3, which in turn causes the sub-beam 11 to be tightened by the beam connecting assembly 12.

[0153] like Figure 6-9As shown, the beam connection assembly 12 also includes several locating pins 4 located between the first connector 1 and the second connector 2. The function of the locating pins 4 is to ensure the horizontal relative position of the first connector 1 and the second connector 2, so that the threaded through hole p and the blind hole q are always aligned.

[0154] like Figure 6 As shown, the beam connection assembly 12 is symmetrically provided with a pair of positioning pins 4: a first positioning pin 4a and a second positioning pin 4b.

[0155] Furthermore, such as Figure 6-9 As shown, the first connector 1 and the second connector 2 are provided with opposing positioning hole groups. The positioning hole groups include a positioning through hole t on the first connector 1 and a positioning blind hole y on the second connector 2. The two ends of the positioning pin 4 extend into the positioning hole groups to horizontally limit the first connector 1 and the second connector 2. The first connector 1 can move relative to the second connector 2 along the axial direction of the positioning pin 4.

[0156] In this embodiment, as Figure 7 As shown, the first connecting member 1 is symmetrically provided with a first positioning through hole t1 and a second positioning through hole t2, and the second connecting member 2 is provided with a first positioning blind hole y1 and a second positioning blind hole y2. A first positioning pin 4a is inserted between the first positioning through hole t1 and the first positioning blind hole y1, and a second positioning pin 4b is inserted between the second positioning through hole t2 and the second positioning blind hole y2. This symmetrical arrangement of positioning pins can maintain the accuracy of the positioning of the first connecting member 1 and the second connecting member 2, and is also conducive to maintaining their balance, which is more conducive to the insertion and assembly of the beam connecting assembly 12 and the two sub-beams 11.

[0157] like Figure 6-9 As shown, the outer contours of the first connector 1 and the second connector 2 are adapted to the inner contours of the transverse slot M, that is, the widths of the first connector 1 and the second connector 2 are approximately matched with the slot width of the transverse slot M. Both the first connector 1 and the second connector 2 are U-shaped cross-section structures formed by their top walls and side walls. When the beam 11 is tightened by the beam connecting assembly 12, the top walls of the first connector 1 and the second connector 2 abut against the inner sides of the first slot wall e and the second slot wall f, respectively, while the side walls of the first connector 1 and the second connector 2 are close to the inner side walls of the transverse slot M, thereby providing reinforcement and support.

[0158] like Figure 4 As shown, in the spliced ​​state, the splicing ends of adjacent beams 11 are close to each other, and the outer surfaces of the two beams 11 form a whole. This not only makes the appearance more aesthetically pleasing and less prone to dust and dirt embedding, but also further strengthens the connection by using the contact between the two, making the beam system 101 more stable and reliable.

[0159] like Figure 6 , 8As shown, the first connecting member 1 has an inner limiting hole v; the sub-beam 11 also has a corresponding outer limiting hole w on a groove wall adjacent to the inner limiting hole v. A first limiting pin 5a is disposed on the first sub-beam 11a, and a second limiting pin 5b is disposed on the second sub-beam 11b. The first limiting pin 5a passes through the first outer limiting hole w1 of the first sub-beam 11a and extends into the corresponding first inner limiting hole v1; the second limiting pin 5b passes through the second outer limiting hole w2 of the second sub-beam 11b and extends into the corresponding second inner limiting hole v2, thereby limiting the depth of the connecting component inserted into the transverse slot M of the sub-beam 11. Of course, the inner limiting hole v can also be provided on the second connecting member 2.

[0160] First, limiting the insertion depth facilitates the assembly of the sub-beam 11 and the beam connection assembly 12, ensuring that the mounting through hole k, threaded through hole p, and blind hole q remain aligned during assembly. Simultaneously, the limiting pin 5 also restricts the horizontal displacement of the beam connection assembly 12 and the sub-beam 11 after assembly, further enhancing the stability and robustness of the connection structure between adjacent sub-beams 11.

[0161] Based on the above, this embodiment also provides an assembly method for a splicing frame system 100 of a sunshade.

[0162] The assembly includes the aforementioned spliced ​​beam system 101. Specifically, it includes a first sub-beam 11a, a second sub-beam 11b, a beam connection assembly 12, and a fastening assembly 13.

[0163] Its assembly process includes at least the following sub-steps;

[0164] Step A: Use locating pin 4 to position and connect the first connector 1 and the second connector 2 relative to each other, so that the threaded through hole p and the corresponding blind hole q at each end are coaxially opposite.

[0165] Step B: Insert the first ends of the positioned first connector 1 and second connector 2 into the transverse slot M of the first sub-beam 11a.

[0166] Step C: Insert the second ends of the positioned first connector 1 and second connector 2 into the transverse slot M of the second beam 11b.

[0167] Step D1: Align the first threaded through hole p1 at the first end of the first connector 1 with the mounting through hole k1 of the first sub-beam 11a, and form a first screwing channel corresponding to the first mounting through hole k1, the first threaded through hole p1 and the first blind hole q1.

[0168] Step D2: Connect the slot of the second beam 11b to the second end of the first connector 1 and the second connector 2, forming a second screwing channel corresponding to the second mounting through hole k2, the second threaded through hole p2 and the second blind hole q2.

[0169] Step E1: Insert the first threaded fastening pin 3a into the first screwing channel.

[0170] Step E2: Insert the second threaded fastening pin 3b into the second screwing channel.

[0171] Step H1: Tighten the first threaded fastening pin 3a to the limit position.

[0172] Step H2: Tighten the second threaded fastening pin 3b to the limit position.

[0173] Although steps D1 and D2, E1 and E2, and H1 and H2 are of the same type, each step is an independent step, and steps of the same type do not need to be completed simultaneously or in an adjacent order.

[0174] In sub-steps H1 and H2, the first step essentially accomplishes the following: with the end of the threaded fastening pin 3 abutting against the bottom of the corresponding blind hole q, the threaded fastening pin 3 is continued to be screwed on, the first connecting piece 1 and the second connecting piece 2 move away from each other along the axial direction of the threaded fastening pin 3, the first connecting piece 1 abuts tightly against the inner side of the first groove wall e of the sub-beam 11, and the second connecting piece 2 abuts tightly against the inner side of the second groove wall f of the sub-beam 11, thereby causing the sub-beam 11 to be tightened by the beam connecting assembly 12.

[0175] In sub-steps H1 and H2, the latter step essentially accomplishes the following: when the first connector 1 and the second connector 2 have been opened and one end is tightened within a sub-beam 11, the threaded fastening pin 3 at the other end is screwed to the limit to ensure that the first connector 1 and the second connector 2 are also in a state of tightening the corresponding sub-beam 11 at the other end.

[0176] It should be noted that the order of the above steps can be adjusted accordingly.

[0177] like Figure 10-11 As shown, in a preferred embodiment, the assembly steps include the following steps in sequence:

[0178] S1: After positioning the first connector 1 and the first connector 2 with the positioning pin 4, insert the first ends into the transverse slot M of the first sub-beam 11a.

[0179] S2: Align the first threaded through hole p1 at the first end of the first connector 1 with the first mounting through hole k1 of the first sub-beam 11a, and form a first screwing channel corresponding to the first mounting through hole k1, the first threaded through hole p1 and the first blind hole q1.

[0180] S3: Insert the first threaded fastening pin 3a into the first screwing channel and continue to screw it. The first connecting piece 1 and the second connecting piece 2 move away from each other along the axial direction of the threaded fastening pin 3 until the first sub-beam 11a is tightened.

[0181] S4: Connect the slot of the second beam 11b to the second end of the first connector 1 and the second connector 2, and form a second screwing channel corresponding to the second mounting through hole k2, the second threaded through hole p2 and the second blind hole q2.

[0182] S5: Insert the second threaded fastening pin 3b into the second screwing channel and continue screwing until the screwing limit is reached, and the first sub-beam 11a and the second sub-beam 11b are spliced ​​together.

[0183] In another preferred embodiment, the assembly steps include the following steps in sequence:

[0184] The assembly process includes the following steps in sequence;

[0185] S1: After positioning the first connector 1 and the first connector 2 with the positioning pin 4, insert the first ends into the transverse slot M of the first sub-beam 11a.

[0186] S2: The first limiting pin 5a passes through the first outer limiting hole w1 of the first sub-beam 11a and extends into the first inner limiting hole v1 at the corresponding position of the first connector 1. The first mounting through hole k1 of the first sub-beam 11a forms a first screwing channel with the corresponding first threaded through hole p1 and first blind hole q1.

[0187] S3: Connect the transverse slot M of the second sub-beam 11b to the second end of the first connector 1 and the second connector 2.

[0188] S4: The second limiting pin 5b passes through the second outer limiting hole w2 of the second sub-beam 11b and extends into the second inner limiting hole v2 at the corresponding position of the first connector 1. The second mounting through hole k2 of the second sub-beam 11b and the corresponding second threaded through hole p2 and second blind hole q2 form a second screwing channel.

[0189] S5: Insert the first threaded fastening pin 3a and the second threaded fastening pin 3b into the corresponding screwing channels and continue to screw. The first connecting piece 1 and the second connecting piece 2 move away along the axial direction of the threaded fastening pin 3 until the corresponding sub-beam 11 is tightened and spliced.

[0190] In the above two implementation schemes, the transverse slot M of the second sub-beam 11b is inserted into the second end of the first connector 1 and the second connector 2 and then closely abuts the splicing ends of the first sub-beam 11a and the second sub-beam 11b, thereby aligning the mounting through hole k of the second sub-beam 11b with the corresponding threaded through hole p and the blind hole q to form a second screwing channel.

[0191] Preferably, such as Figure 6 , 10 As shown, in order to decorate the beam 11 and to prevent dust and moisture, the external opening of the mounting through hole k is sealed with a sealant plug 6.

[0192] Preferred, such as Figure 5 As shown, the side wall of the sub-beam 11 is also provided with a connecting hole. The first sub-beam 11a and the second sub-beam 11b after the above splicing are connected by a connecting strip 9 whose end is fixed in the connecting hole by a fastening screw, so as to further enhance the connection stability.
