Description

Technical Field

[0001] The present invention relates to the technical field of tent cars, and specifically, to a tent skeleton structure and a tent car. Background Art

[0002] For long-term or short-term use in the wild during field team investigations, camping, exploration, construction, disaster relief, and flood control, tents are generally required, that is, sheds supported on the ground to shield against wind, rain, sunlight, and for temporary residence. Tents are mostly composed of several horizontal and vertical beams of different lengths and are erected by on-site assembly. During the erection process, the tent skeleton is first lapped, and then the tarpaulin and periphery are installed.

[0003] However, the existing tents generally have a small unfolded area, a narrow space, and can accommodate few people. Under the same number of accommodated people, frequent erection is required, which restricts the erection efficiency; and during the erection process of the tent, the larger the tent, the more people are required for installation, and the longer the installation time, resulting in difficulties in erection and low erection efficiency; in addition, for relatively complex large tents, it often requires skilled training to install and disassemble the tent, and it takes several hours to complete, with a relatively large overall installation difficulty. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies of the prior art, the present invention provides a tent skeleton structure and a tent car, which can realize the rapid folding and unfolding of the tent, with low erection difficulty and high erection efficiency.

[0005] To achieve the above object, the present invention provides a tent, which includes:

[0006] A central column; and

[0007] A skeleton assembly connected to the central column and capable of switching between a folded state and an unfolded state;

[0008] Wherein, the skeleton assembly includes a plurality of main skeleton units arranged at intervals in the circumferential direction around the central column and diverging radially in the unfolded state, and the radially inner ends between adjacent main skeleton units are hinged to each other. In the folded state, the plurality of main skeleton units move along the circumferential direction of the central column to contract and approach each other.

[0009] In some embodiments, the main skeleton unit is in a flat plate shape, the radially inner end of the main skeleton unit is parallel to the edge of the central column, and among the adjacent radially inner ends, the upper ends of the radially inner ends are hinged to each other and the lower ends are hinged to each other.

[0010] In some embodiments, the upper edge of the radial inner end is connected to an upper unit connecting plate with a lateral pin hole and the lower edge is connected to a lower unit connecting plate with a lateral pin hole, and adjacent radial inner ends are pivotally connected by unit connecting pins that pass through the lateral pin holes of the upper unit connecting plate and the lateral pin holes of the lower unit connecting plate.

[0011] In some embodiments, the main skeleton unit is a truss structure.

[0012] In some embodiments, one of the plurality of unit connecting pins is a main pivot axis, and a pivot connection around the main pivot axis is formed between the skeleton assembly and the central column.

[0013] In some embodiments, in the expanded state, the radial inner ends of the main skeleton units are arranged around the central column and spaced apart along the circumferential direction, and in the folded state, the skeleton assembly is in a rectangular stacked shape, with the radial inner ends aligned with each other.

[0014] In some embodiments, the skeleton assembly includes a plurality of sub-skeleton units, and the sub-skeleton units are arranged alternately with the main skeleton units along the circumferential direction.

[0015] In some embodiments, the radial outer end of the main skeleton unit is hinged with an annular connecting plate, which is stacked on the circumferential side of the main skeleton unit in the folded state, and is connected to the radial outer end of the secondary skeleton unit in the unfolded state.

[0038] The following will describe in detail the specific implementation manners of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0039] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with exemplary embodiments.

[0041] In an exemplary embodiment of the present invention, a tent is provided. Refer to Figures 1 to 10 , the tent includes:

[0042] A central column 100; and

[0043] A skeleton assembly 200. Refer to Figure 1 、 Figure 5 , the skeleton assembly 200 is connected to the central column 100 and can be switched between a folded state and an unfolded state;

[0044] Wherein, the skeleton assembly 200 includes a plurality of main skeleton units 201 that are arranged at intervals in the circumferential direction around the central column 100 and diverge radially in the unfolded state. The radially inner ends between adjacent main skeleton units 201 are hinged to each other. In the folded state, the plurality of main skeleton units 201 move along the circumferential direction of the central column 100 to contract and approach each other.

[0045] The present invention aims to solve the problems of low integration degree of the tent structure, difficult field erection and retraction, and low installation efficiency in the prior art. Since tents used in the field are mostly composed of several transverse and longitudinal beams, which increases the installation difficulty and restricts the erection efficiency of the tent. It is necessary to fully consider the retraction and erection efficiency from the structural level. Therefore, based on the objective conditions of field erection of tents, the degree of fragmentation of the tent skeleton should be controlled, and an integrated retractable and erectable skeleton should be formed as much as possible to fully improve its erection efficiency and reduce its installation difficulty.

[0046] In this embodiment, a structural design of a large tent skeleton structure and a tent vehicle that can be quickly unfolded is specifically proposed. Specifically, refer to Figure 5, in this embodiment, the central column 100 is designed with a top fan-shaped structure and a bottom multi-faceted cavity structure, but its shape and structure are not limited to the illustrated structure as long as it can play a role in supporting and connecting. Further, a fixed support hinge point is provided at any position in the circumferential direction of the multi-faceted cavity to connect the framework assembly 200 to the central column 100, that is, the framework assembly 200 and the central column 100 are connected at a single point. In other words, the fixed support hinge point is the load-bearing point, thus forming an integrated structure of the central column 100 and the framework assembly 200.

[0047] The framework assembly 200 includes two states, namely the folded state as Figure 5 shown and the unfolded state as Figure 1 shown. The framework assembly 200 adopts a structure in which several main framework units are arranged at intervals. In its unfolded state, it can form an umbrella-bone type radially divergent structure, and in the folded state, it can form a rectangular laminated structure, with regular structure and good tent unfolding and folding effects.

[0048] In this embodiment, the main framework unit 201 is in a flat plate shape, and the radially inner end edge 1 of the main framework unit 201 is parallel to the edge of the central column 100, that is, the setting direction of the main framework unit 201 is the same as that of the central column 100. Among the adjacent radially inner end edges 1, the upper edge ends of the radially inner end edges 1 are hinged to each other and the lower edge ends are hinged to each other. Further, the main framework unit 201 is a truss structure, as Figure 6 shown. The main framework unit 201 is composed of straight rods and has a planar structure containing several triangular units inside. Among them, the straight rods mainly bear axial tension and pressure, making full use of the material strength. The internal triangular unit design can reduce the self-weight. The adjacent flat plate-shaped main framework units are hinged to each other to form an integrated structure, and the truss structure has a large span adaptation range, a large structural space, a small lateral stiffness and a spatial stiffness. Therefore, the long-arm main framework unit 201 can be used, having the structural strength for constructing a large tent.

[0049] In this embodiment, refer to Figure 5, the upper edge end of the radial inner end edge 1 is connected with an upper unit connecting piece 2 with a lateral pin hole, and the lower edge end is connected with a lower unit connecting piece 3 with a lateral pin hole. The radial inner end edge 1, the upper unit connecting piece 2 and the lower unit connecting piece 3 together form an I-shaped structure, and the adjacent I-shaped structures can be I-shaped structures with the connecting piece parts of different heights overlapping each other. The adjacent radial inner end edges 1 are pivotally connected through a unit connecting pin shaft 4 passing through the lateral pin holes of the upper unit connecting piece 2 and the lateral pin holes of the lower unit connecting piece 3. The upper unit connecting piece 2 and the lower unit connecting piece 3 are sheet-like structures with the same structure. Of course, the shapes of the upper unit connecting piece 2 and the lower unit connecting piece 3 are not limited to the sheet-like structures shown in the figure. The main frame unit 201 where the adjacent upper unit connecting piece 2 and the lower unit connecting piece 3 are connected pivots horizontally around the unit connecting pin shaft 4. Further, one of the multiple unit connecting pin shafts 4 is the main pivot shaft, and a pivotal connection around the main pivot shaft is formed between the frame assembly 200 and the central column 100, so that the frame assembly 200 and the central column 100 present a single-point connection of the main pivot shaft. In other words, the fixed support hinge point is the load-bearing point, thereby forming an integrated structure of the central column 100 and the frame assembly 200. Of course, it is not limited to the single-point connection mentioned in this embodiment.

[0050] See Figure 1 , in the unfolded state, the radial inner end edges 1 of each main frame unit 201 are arranged around the central column 100 at intervals in the circumferential direction. The main frame units 201 are arranged at intervals, which can not only ensure the support effect of the main frame units 201 in the unfolded state, but also reduce the overall self-weight of the main frame units 201. It should be noted that when the main frame unit 201 is in the unfolded state, both ends of the enclosure are the main frame units 201 to increase the firmness of the enclosure end in the unfolded state. See Figure 5 , in the folded state, the frame assembly 200 is in a rectangular laminated shape, and the radial inner end edges 1 are aligned with each other. When in the folded state, the frame assembly 200 is arranged in a rectangle, and the tightness between the structures is high, reducing the occupied space and being in a storage state. Of course, the shape in the folded state is not limited to the rectangular structure shown in the figure, as long as it can ensure laminated storage.

[0051] Among them, when a field team needs to install and unfold the tent, as Figure 5 shows the initial state of the tent frame, that is, the folded state. The installer holds the end-side main frame unit 201 of the rectangular laminated frame assembly 200 and pulls the end-side main frame unit 201 along the Figure 2 arrow direction drawn horizontally in Figure 1 . The adjacent main frame units 201 are connected through the upper unit connecting piece 2 and the lower unit connecting piece 3. Therefore, during the unfolding process, each main frame unit 201 is in a linkage state and quickly unfolds to the unfolded state around the central column 100 in the circumferential direction as shown in . When it is necessary to fold the tent frame, just alongFigure 1 Pull the end main skeleton unit 201 in the direction of the arrow drawn horizontally, which also causes each main skeleton unit 201 to be in a linked state, and can be quickly folded into the following state: Figure 5 The rectangular folded shape shown.

[0052] See also Figure 1 and Figure 10 The skeleton assembly 200 includes a plurality of sub-skeleton units 202, and the sub-skeleton units 202 and the main skeleton units 201 are arranged alternately in the circumferential direction. The sub-skeleton units 202 and the main skeleton units 201 are arranged alternately, wherein the main skeleton unit 201, as the main structure of the tent skeleton, plays a main supporting role, and the sub-skeleton units play an auxiliary supporting role, mainly used to provide upper support for the tarpaulin to ensure that the tarpaulin does not collapse, wherein the radial inner end of the sub-skeleton unit 202 is hinged to the corresponding upper unit connecting piece 2, thereby realizing the integrated connection between the main skeleton unit 201 and the sub-skeleton unit 202, and when unfolding or folding, the sub-skeleton unit 202 follows the main skeleton unit in linkage to realize the rapid retraction and extension of the skeleton assembly 200.

[0053] See also Figure 1 and Figure 2 The radial outer end of the main skeleton unit 201 is hinged with an annular connecting plate 5, which is stacked on the circumferential side of the main skeleton unit 201 in the folded state and connected to the radial outer end of the auxiliary skeleton unit 202 in the unfolded state. Figure 8 and 9 As shown, the annular connecting plate 5 rotates with M / M' as the hinge point, wherein the annular connecting plate 5 is a rectangular structure formed by welding rectangular tubes. Of course, the shape of the annular connecting plate 5 is not limited to the rectangular tube shown in the figure, and can also be a circular structure or other structures. The number of annular connecting plates 5 in the entire tent is twice the number of main frame units 201. One end of the annular connecting plate 5 is hinged to the main frame unit 201, which can be realized as follows Figure 9 The folded state and Figure 8 When in the unfolded state, the other end of the adjacent annular connecting plate 5 is as Figure 1 As shown, they are close to each other and connected and fixed by buckles. At the same time, the radial outer end of the sub-skeleton unit 202 is also provided with a fixing device, which is connected and fixed with the buckle in the unfolded state, thereby realizing the unfolding, enclosing and fixing of the main skeleton unit 201, the sub-skeleton unit 202 and the annular connecting plate 5. It should be noted that the buckle and the fixing device can adopt the general conventional buckle and fixing device known to technical personnel in this field. In order to avoid blurring the focus, they are not described here and are not shown in the figure.

[0054] See also Figure 6 and Figure 7In order to be able to adjust the horizontal height of the fulcrum of the main frame unit 201 according to the flatness of the tent installation plane, the radial outer end of the main frame unit 201 is hinged with a telescopic support leg 6, wherein the telescopic support leg 6 includes a support column 601 hinged to the radial outer end of the main frame unit 201, and the movable end of the support column 601 is plugged into the telescopic support foot plate 602. Furthermore, an outer positioning hole is provided on the support column 601, and a plurality of inner positioning holes are provided on the telescopic support foot plate 602, and the outer positioning holes and the inner positioning holes are connected and fixed by a pin. In order to realize the retraction, extension and fixation of the telescopic supporting leg 6, a retractable rib connecting rib 7 is provided between the main skeleton unit 201 and the telescopic supporting leg 6, wherein the rib connecting rib 7 includes an inclined column 701 hinged to the radial outer end of the main skeleton unit 201, and a telescopic column 702 hinged to the supporting column 601, and the telescopic column 702 is plugged into the inclined column 701. Furthermore, an outer positioning hole is provided on the inclined column 701, and an inner positioning hole is provided on the telescopic column 702, and the corresponding outer positioning hole and the inner positioning hole are connected and fixed by a pin.

[0055] like Figure 7 As shown in the figure, the telescopic support leg 6 and the rib connecting rib 7 are both in a folded state. When the telescopic support leg 6 needs to be opened, the latch can be pulled out first, and the telescopic support leg 6 can be moved to rotate the telescopic support leg 6 around point N to Figure 6 The position shown, at the same time, the telescopic column 702 slides out along the inclined column 701, and the length of the rib connecting rib can be fixed by inserting the pin into the outer positioning hole and the corresponding inner positioning hole, thereby fixing the position of the telescopic support leg 6, and by pulling the telescopic support foot plate 602 to slide it in and out along the telescopic support leg 6, and fixing the outer positioning hole and the corresponding inner positioning hole by the pin, the length of the telescopic support leg 6 can be adjusted, so that the frame assembly 200 always remains horizontal, thereby enhancing the adaptability and practicality of the tent frame installation.

[0056] The deployment and retraction of the above structure are mutually inverse processes and will not be described in detail.

[0057] The tent vehicle includes the tent in the above-mentioned embodiment. The body structure of the tent vehicle can adopt a general conventional tent vehicle well known to those skilled in the art. To avoid blurring the focus, it will not be described here and is not shown in the figure.

[0058] In summary, the tent and tent vehicle of the present invention have reasonable structures, the connection structures of the tent frames are self-contained, and no other structures need to be added during the folding and unfolding process. The tent frame can be quickly unfolded and retracted, with low installation difficulty and high folding and unfolding efficiency.
