Description

Technical Field

[0001] The invention belongs to the technical field of outdoor equipment and relates to a tent, in particular to an outer cover of a tent. Background Art

[0002] As people's living standards improve, they are engaging in more and more outdoor activities. For outdoor camping, people often carry tents and related equipment. A tent is a shed that can be propped up on the ground to shelter from wind, rain, and sunlight and provide a place for people to rest or temporarily live. And as the number of private cars continues to grow, self-driving travel has become a new type of outdoor activity. In order to meet the convenience of self-driving travel, the structure of traditional tents has been improved to form rooftop tents that can be installed on the roof of a car.

[0003] The roof tent is fixed on the roof of the vehicle, and is folded and contracted to form a box-like shape when not in use. Its structure is disclosed in the Chinese patent application number 201921172456.0, which is a portable roof tent that is easy to load and unload. It includes a top cover, a bottom cover, a supporting top piece, a tent frame and a tarpaulin. The top cover is hinged to the rear side of the bottom cover and can be buckled with the bottom cover. The top cover includes a plurality of top frames and a plurality of corner connectors. The top cover is surrounded by the top frames and the corner connectors to form a frame structure. The top frame includes a frame body and a mounting portion of an integral structure. One side of the frame body extends outward to form the mounting portion, and the frame body and the mounting portion are L-shaped. The frame bodies of the top frame are detachably connected by corner connectors, and the supporting top piece is telescopically arranged between the top cover and the bottom cover. The top frame also includes a positioning portion of an integrated structure, the frame body is a hollow structure with a hollow cavity, the mounting portion is provided with a first mounting groove along the length direction of the frame body, the bottom of the first mounting groove extends toward its opening direction to form the positioning portion, the top cover also includes a top plate, the top frame and the corner connector are connected around the top plate, and the periphery of the top plate is inserted into the first mounting groove and fixed to the top frame. The setting of the frame body greatly reduces the overall weight, making the tent more portable. In addition, by setting a luggage rack on the top of the top cover, it can also carry goods.

[0004] However, this lightweight roof tent that is easy to load and unload also has some disadvantages: the top cover is only formed by connecting the top frame and the corner connector. Although the weight is reduced, it can only adopt a split structure such as the top cover and the top plate, and the top plate generally only directly adopts the outer layer. When the user places heavy objects such as luggage on the top cover for transportation, the pressure generated by the weight of the objects is directly applied to the top plate, which is easy to deform downward over time, thereby causing the entire outer cover to deform. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to provide an outer cover of a tent, which solves the problem of insufficient strength when reducing weight.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] The outer cover of a tent comprises a rectangular profile outer frame and a cover plate connected to the inner side of the profile outer frame, wherein the inner sides of the four sides of the profile outer frame are provided with slots, and the cover plate is inserted into the slots on all sides. The invention is characterized in that the cover plate is composed of a middle layer fixedly connected to each other and outer layers located on both sides of the middle layer, the two outer layers are metal plates of the same shape, the middle layer comprises a support frame, the support frame is surrounded by a plurality of side edges to form a frame of the same shape as the outer layer, the frame is provided with a plurality of reinforcing strips whose two ends are fixedly connected to the side edges, and the frame is provided with a honeycomb core.

[0008] The outer cover can be the outer shell top or the outer shell bottom of the tent. When assembling, the four sides of the cover plate are inserted into the grooves on the inner sides of the four sides of the profile outer frame to combine the cover plate and the profile outer frame to form the outer cover. The use of the profile outer frame makes the weight of the entire outer cover lighter; and through the arrangement of the two outer layers in conjunction with the honeycomb core, the cover plate forms a structure similar to that of a honeycomb plate, but the middle layer of the cover plate has a support frame, and the support frame is surrounded by a plurality of side edges to form a frame of the same shape as the outer layer, and the frame has a plurality of reinforcing strips with both ends fixedly connected to the side edges, and the reinforcing strips make the strength of the frame itself relatively high, and the two outer layers are connected to the frame together to form a skeleton with a more solid structure and higher strength, so that a strong support is formed when the cover plate is load-bearing, and the strength of the cover plate is better than that of a conventional honeycomb plate, so that it has a better load-bearing capacity, whether it is for carrying objects after the tent is folded up (when the outer cover is used as the top of the outer shell of the tent) or when people sit in the tent to rest when the tent is opened (when the outer cover is used as the bottom of the outer shell of the tent), it is not easy to be deformed by force, so that the outer cover can reduce the weight while having a sufficiently high structural strength.

[0009] In the outer cover of the above tent, the two ends of the reinforcing strip are respectively fixedly connected to the two parallel sides of the support frame, and each reinforcing strip divides the inner side of the frame into several areas, each area is filled with a honeycomb core.

[0010] Compared with using a whole piece of honeycomb core, the use of multiple small honeycomb cores makes it have better load-bearing capacity, more reliable use, and stronger resistance to deformation.

[0011] In the outer cover of the above tent, the support frame is formed by welding a plurality of hollow square aluminum tubes.

[0012] In the outer cover of the above tent, the outer layer is an aluminum sheet, and the honeycomb core is an aluminum honeycomb core.

[0013] The use of aluminum tube welding, aluminum sheets and aluminum honeycomb cores makes the cover lighter but light enough.

[0014] In the outer cover of the above-mentioned tent, the profile outer frame includes four aluminum profiles, and the inner side wall of the aluminum profile is fixedly connected with oppositely arranged protrusions 1 and 2, which are arranged along the length direction of the aluminum profile and form the above-mentioned slot for clamping the cover plate therebetween.

[0015] The profile frame is formed by connecting four aluminum profiles. During assembly, the four aluminum profiles are first clamped on the four sides of the cover through the clamping grooves and then connected to form the profile frame. The formed profile frame is light in weight and high in strength.

[0016] In the outer cover of the above tent, the cover plate and the profile frame are fixed by fasteners that pass through the first convex piece and the outer layer from the outside and penetrate into the support frame, and fasteners that pass through the second convex piece and the other outer layer from the outside and penetrate into the side of the support frame.

[0017] The arrangement of the first and second convex pieces and the support frame enables the profile outer frame and the cover plate to be fixed by fasteners, thereby making the structure of the entire outer cover more solid. In conventional honeycomb panels, the two outer layers are generally too thin to be fixed by fasteners.

[0018] In the outer cover of the tent, the widths of the first and second protrusions are both greater than the widths of the corresponding sides of the support frame.

[0019] In the outer cover of the above tent, the aluminum profile is in the shape of a hollow square tube, and the outer side of each aluminum profile has a plurality of strip slide grooves with a T-shaped cross section, and each strip slide groove is arranged along the length direction of the aluminum profile.

[0020] The provision of the strip slide allows the user to arrange some auxiliary accessories that can slide along the strip slide in the strip slide when assembling the profile frame, so as to assist in fixing other objects such as luggage or mountain bikes on the tent when not in use.

[0021] In the outer cover of the tent, a reinforcing rib is fixedly connected to the inner cavity wall of the aluminum profile corresponding to the bottom wall of the strip-shaped slide groove.

[0022] The provision of the reinforcing ribs can improve the strength of the aluminum profile and prevent deformation caused by the weight of the object exerting pressure on the strip slide through the auxiliary accessories.

[0023] In the outer cover of the above tent, outer side walls of two parallel aluminum profiles among the four aluminum profiles have inclined drag-reducing surfaces.

[0024] When the outer cover is used as the top of the tent shell, the drag reduction surface can reduce the air resistance encountered by the car during driving.

[0025] In the outer cover of the above tent, the profile outer frame further includes four corner connectors, which are L-shaped. Each corner connector abuts against the inner side walls of two adjacent aluminum profiles and is fixed to the aluminum profiles via fasteners.

[0026] The four aluminum profiles are connected into a whole through four corner connectors. The corner connectors are L-shaped and respectively abut against the inner side walls of two adjacent aluminum profiles, so that a firm connection is formed between the two adjacent aluminum profiles, thereby improving the strength of the entire outer cover.

[0027] In the outer cover of the tent, one end of the corner connector is respectively against two protruding pieces on two adjacent aluminum profiles.

[0028] One end of the corner connector is respectively against the convex pieces 2 on the two adjacent aluminum profiles, so that the corner connector can also provide a certain support to the convex piece 2 to prevent the convex piece 2 from deforming inward due to force. In addition, the corner connector also provides a certain support to the cover plate through the convex piece 2, further enhancing the load-bearing capacity of the cover plate and improving the structural strength of the entire outer cover.

[0029] In the outer cover of the above-mentioned tent, the outer cover also includes a rectangular sealing frame, one side of the rectangular sealing frame is integrally connected with a rectangular connecting frame, the area of ​​the rectangular connecting frame is larger than the rectangular sealing frame, and slots are opened along the four sides of the rectangular connecting frame. The rectangular connecting frame is located at the other side of the profile outer frame. The four aluminum profiles are provided with L-shaped plug-in pieces, the bent part of the plug-in piece is parallel to the protruding piece and the two are arranged in the same direction, and the bent parts of the plug-in pieces on the four aluminum profiles are inserted into the slots on the rectangular connecting frame.

[0030] While clamping the four aluminum profiles around the support frame, ensure that the bent parts of the plug-in pieces on the four aluminum profiles are inserted into the slots around the rectangular connection frame, so that the rectangular sealing frame can be directly fixed to the profile frame when the profile frame is assembled. The setting of the rectangular sealing frame can play a sealing role when the tent is folded, preventing rainwater from seeping in and wetting the inside of the tent. In addition, this method makes the connection between the rectangular sealing frame and the profile frame easier, and there is no need to use additional fasteners for fixing.

[0031] Compared with the prior art, the outer cover of the tent has the following advantages:

[0032] 1. The use of profile outer frame makes the weight of the entire outer cover lighter, and the inner core composed of two outer layers, honeycomb core and support frame makes the cover plate have better load-bearing capacity and is not easy to deform under force, so that the outer cover can reduce weight while having a sufficiently high structural strength;

[0033] 2. The use of corner connectors makes the connection between two adjacent aluminum profiles more secure, improves the firmness of the formed profile frame, and at the same time, the corner connectors can support the cover plate, further improving the strength of the entire outer cover;

[0034] 3. The setting of the plug-in piece enables the four aluminum profiles to be connected to form the profile frame and can directly fix the rectangular sealing frame at the same time, so that the tent can be sealed by the rectangular sealing frame when not in use, thereby improving the sealing performance.

DETAILED DESCRIPTION

[0045] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0046] like Figure 1 and Figure 2 As shown, the tent comprises a square outer shell 1 which can be opened and closed, and a closed accommodating cavity is provided inside the closed outer shell 1. The outer shell 1 comprises two outer covers 2 which are hinged on one side. When the tent is fixed on the roof, one of the outer covers 2 is used as the bottom of the outer shell 1, and the other outer cover 2 is used as the top of the outer shell 1. A hinge seat is fixed on one side of the two outer covers 2, and the two hinge seats are hinged so that the outer shell 1 can be opened and closed. A supporting connecting rod 3 is connected between the side walls of the two outer covers 2. The supporting connecting rod 3 can be controlled manually or electrically. When the outer cover 2 which is used as the top of the outer shell 1 swings around the hinge point to make the outer shell 1 in an open state, the supporting connecting rod 3 can support the outer cover 2 to keep it in the open state. The outer cover 2 which is used as the bottom of the outer shell 1 is hinged on the other side with a supporting cover 4, and the supporting cover 4 can swing inward around the hinge point to be received into the inner side of the accommodating cavity or swing outward to be flush with the outer cover 2 in the horizontal direction. The tent also includes a U-shaped tent frame 5, the two ends of which are connected to the hinge points of the support cover 4 and the outer cover 2 used as the bottom of the outer shell 1. When the support cover 4 swings outward around the hinge point, it can drive the tent frame 5 to swing outward. The tent also includes a tarpaulin 6, the edges of which are fixed to the two outer covers 2 and the support cover 4, and the tarpaulin 6 is sleeved outside the tent frame 5. When the outer shell 1 and the support cover 4 are opened, the entire tarpaulin 6 can be unfolded to form a space for users to rest inside. In order to enable the tent to be used on the roof of a car, two slide rails can be fixed at the bottom of the outer cover 2 used as the bottom of the outer shell 1, and two slide bars can be fixed on the roof of the car, so that the tent can be installed on the roof of the car by sliding the slide bars into the slide rails.

[0047] like Figure 3-Figure 9As shown, the two outer covers 2 each include a profile outer frame 2a and a cover plate 2b connected to the inner side of the profile outer frame 2a. The inner sides of the four sides of the profile outer frame 2a are provided with slots 2a11, and the cover plate 2b is inserted into each slot 2a11 around the four sides. The cover plate 2b is composed of a middle layer fixedly connected to each other and an outer layer 2b1 located on both sides of the middle layer. The two outer layers 2b2 are metal plates of the same shape, and are specifically aluminum thin plates. The middle layer includes a support frame 2b2, and the support frame 2b2 is surrounded by a plurality of side edges to form a frame 2b21 of the same shape as the outer layer 2b1. The outer layer 2b2 is square and the frame 2b21 is also square of the same size. The frame 2b21 has a plurality of reinforcing strips 2b22 whose two ends are fixedly connected to the side edges of the support frame 2b2. The frame 2b21 is provided with a honeycomb core 2b3, and is specifically an aluminum honeycomb core. The side edges of the support frame 2b2 are embedded in the slots 2a11. The structure of the support cover 4 is similar to that of the outer cover 2, and will not be described in detail here. Furthermore, the two ends of the reinforcing strip 2b22 are respectively fixedly connected to the two parallel sides of the support frame 2b2, and each reinforcing strip 2b22 divides the inner side of the frame 2b21 into several areas, each of which is filled with a honeycomb core 2b3. The support frame 2b2 is specifically formed by welding several hollow square aluminum tubes.

[0048] like Figure 4 , Figure 5 and Figure 8 As shown, the profile frame 2a of the two outer covers 2 includes four aluminum profiles 2a1, and the inner side wall of the aluminum profile 2a1 is fixedly connected with a relatively arranged protrusion 1 2a12 and a protrusion 2a13, and the protrusion 1 2a12 and the protrusion 2a13 are arranged along the length direction of the aluminum profile 2a1, and a groove 2a11 is formed between the protrusion 1 2a12 and the protrusion 2a13, and the width of the protrusion 1 2a12 and the protrusion 2a13 is greater than the width of the corresponding side of the support frame 2b2, so that the depth of the formed groove 2a11 can be greater than the width of the side of the support frame 2b2 corresponding to the groove 2a11. The cover plate 2b and the profile frame 2a are fixed by fasteners that pass through the protrusion 1 2a12 and the outer layer 2b1 from the outside and penetrate into the side of the support frame 2b2, and fasteners that pass through the protrusion 2a13 and another outer layer 2b1 from the outside and penetrate into the support frame 2b2. In addition, during assembly, glue may be applied in the slot 2a11, and when the cover plate 2b is inserted into the slot 2a11 on all sides, the cover plate 2b may be bonded and fixed to the profile outer frame 2a with the help of glue.

[0049] In this embodiment, if Figure 4 and Figure 5 As shown, for the outer cover 2 on the top of the housing 1, cylindrical bars 2a14 are fixedly connected at the convex pieces 2a13 of the four aluminum profiles 2a1. The cylindrical bars 2a14 are arranged along the length direction of the aluminum profiles 2a1 and have an open circular ring shape in cross section. Figure 8As shown, for the outer cover 2 at the bottom of the housing 1, except for the aluminum profile 2a1 hinged to the support cover 4, the outer side walls of the remaining three aluminum profiles 2a1 are fixedly connected with cylindrical bars 2a14, which are arranged along the length direction of the aluminum profile 2a1 and have an open circular ring shape in cross section. The function of the cylindrical bars 2a14 is to cooperate with the tarpaulin 6, fix the T-shaped head at the edge of the tarpaulin 6, and insert each T-shaped head into the corresponding cylindrical bar 2a14.

[0050] like Figure 4 and Figure 5 As shown, for the outer cover 2 used on the top of the shell 1, each aluminum profile 2a1 is in the shape of a hollow square tube, and the outer side of each aluminum profile 2a1 has a strip chute 2a15 with a T-shaped cross section, and each strip chute 2a15 is arranged along the length direction of the aluminum profile 2a1. The arrangement of the strip chute 2a15 enables the user to arrange some auxiliary accessories that can slide along the strip chute 2a15 in the strip chute 2a15 when assembling the profile outer frame 2a, which is used to assist in fixing other objects such as luggage or mountain bikes on the closed shell 1; in addition, it can also be used to directly cooperate with the supporting connecting rod 3. The number of strip chute 2a15 on the outer side of each aluminum profile 2a1 is more than one, and a reinforcing rib 2a16 is fixedly connected to the inner cavity wall of each aluminum profile 2a1 corresponding to the bottom wall of the strip chute 2a15. One of the aluminum profiles 2a1 is hinged to one of the aluminum profiles 2a1 in the outer cover 2 used as the bottom of the shell 1. Furthermore, the outer side walls of the two aluminum profiles 2a1 adjacent to the hinged aluminum profile 2a1 both have inclined drag reduction surfaces 2a17. When the tent is used on the roof of a car, the drag reduction surface 2a17 can reduce the air resistance of the car during driving. Figure 8 As shown, for the outer cover 2 used at the bottom of the outer shell 1, each aluminum profile 2a1 is also in the shape of a hollow square tube, and the outer side of each aluminum profile 2a1 has a strip slide groove 2a15 with a T-shaped cross-section, and each strip slide groove 2a15 is arranged along the length direction of the aluminum profile 2a1.

[0051] like Figure 3 and Figure 6As shown, for the outer cover 2 used as the top of the outer shell 1, its profile frame 2a also includes four corner connectors 2a3. The corner connectors 2a3 are L-shaped (specifically formed by bending a metal plate, especially the outer layer 2b1). Each corner connector 2a3 is respectively abutted against the inner wall of two adjacent aluminum profiles 2a1 and then fixed to the two aluminum profiles 2a1 by fasteners. One end of the corner connector 2a3 is respectively abutted against the convex piece 2a13 on the two adjacent aluminum profiles 2a1. The profile frame 2a further includes four corner plug-ins 2a2. The outer sides of the corner plug-ins 2a2 respectively have a plug-in portion 1 2a21 and a plug-in portion 2a22 inserted into the end portions of two adjacent aluminum profiles 2a1 in the same profile frame 2a, and the outer surfaces of the corner plug-ins 2a2 are respectively flush with the outer surfaces of the two adjacent aluminum profiles 2a1. For the outer cover 2 used as the bottom of the outer shell 1, as shown Figure 7 As shown, the profile outer frame 2a also includes four corner connectors 2a2.

[0052] like Figure 3 , Figure 4 and Figure 5 As shown, further, for the outer cover 2 used as the top of the shell 1, it also includes a rectangular sealing frame 2c, one side of the rectangular sealing frame 2c is integrally connected with a rectangular connecting frame 2c1, and the rectangular sealing frame 2c can be made of rubber. The rectangular connecting frame 2c1 has a larger frame area than the rectangular sealing frame 2c, and slots are provided along the four sides of the rectangular connecting frame 2c1. The cover plate 2b and the rectangular sealing frame 2c are respectively located on both sides of the profile outer frame 2a, and the rectangular connecting frame 2c1 is located at the other side of the profile outer frame 2a. The four aluminum profiles 2a1 are all provided with L-shaped plug-in pieces 2a18, and the bent portion of the plug-in piece 2a18 is parallel to the convex piece 2a12 on the same aluminum profile 2a1 and the two are arranged in the same direction. The bent portions of the plug-in pieces 2a18 on the four aluminum profiles 2a1 are inserted into the slots on the rectangular connecting frame 2c1, and when the shell 1 is closed, the rectangular sealing frame 2c is embedded in the inner side of the outer cover 2 used as the bottom of the shell 1 to form a seal.

[0053] The two outer layers 2b1 are combined with the honeycomb core 2b3 to form a honeycomb structure on the cover plate 2b, which has better load-bearing capacity and anti-deformation ability, while reducing the weight of the outer cover 2 and ensuring that it has a sufficiently high structural strength. In addition, a support frame 2b2 is added to the cover plate 2b, which can form a strong support when the cover plate 2b is bearing weight, so that the strength of the cover plate 2b is better than that of a conventional honeycomb panel.

[0054] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
