Detailed implementation manners

[0041] The following will combine the attached Figure 1 to the attached Figure 5 and embodiments to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0042] Reference to "embodiments" in this document means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0043] The following will be described in detail with reference to specific embodiments. It should be noted that the embodiments of the present application can be presented in various forms, and some examples will be described below.

[0044] In the field of outdoor camping sleep products, the related camping sleeping bags do not have moisture-proof functions; the assembly and installation of camping tents are easily affected by the terrain, and the tents are also easily affected by the ground moisture. The related art also provides a camping bed structure that can avoid being affected by ground moisture. This camping bed structure tightens the bed cloth of the camping bed structure by rotating an eccentric structure through a lever structure. However, the eccentric structure can tighten the camping bed structure with a narrow width. When the camping bed structure is too wide, the acting distance of the eccentric structure for tightening is limited, and the tightening of the bed cloth cannot be achieved, resulting in a poor user experience when lying on the camping bed structure. The comfort and adaptability of the camping bed structure in the related art need to be improved.

[0045] To address the technical problem that the comfort and adaptability of the camping bed structure in the related art need to be improved, the present application provides a camping bed 10. The first wire-tightening mechanism 300 of the camping bed 10 can tighten the bed surface body 110 with different widths, which not only improves the comfort of the camping bed 10 but also improves the adaptability of the camping bed 10.

[0046] Specifically, please refer to Figure 1 , Figure 1 which is the first schematic structural diagram of the camping bed 10 provided by the embodiments of the present application. The camping bed 10 of the present application includes a bed surface assembly 100, a first support frame 200, and a first wire-tightening mechanism 300.

[0047] The bed surface assembly 100 includes a bed surface body 110 and a first tension belt 120. The bed surface body 110 includes a first edge 111 and a second edge 112 that are oppositely arranged. The first tension belt 120 is used to drive the movement of the second edge 112. A first support frame 200 is disposed on one side of the bed surface assembly 100. For example, the first support frame 200 is disposed at the bottom of the bed surface assembly 100. One end of the first support frame 200 is connected to the first edge 111, and the other end of the first support frame 200 is connected to a first wire tightening mechanism 300. The first wire tightening mechanism 300 is also connected to the first tension belt 120. The first wire tightening mechanism 300 is used to rotate under an external force and adjust the length of the first tension belt 120, and make the first tension belt 120 drive the second edge 112 to approach or move away from the first edge 111. When the second edge 112 moves away from the first edge 111, the tension between the first edge 111 and the second edge 112 increases. When the second edge 112 approaches the first edge 111, the tension between the first edge 111 and the second edge 112 decreases.

[0048] It can be understood that the bed surface body 110 is used to carry a user or other objects. The first tension belt 120 can be directly connected to the bed surface body 110, or the first tension belt 120 can be drivingly connected to the bed surface body 110. For example, in some examples, the first tension belt 120 is connected to the second edge 112 of the bed surface body 110. In other examples, the second edge 112 of the bed surface body 110 is connected to a support cross beam, and the first tension belt 120 is connected to the support cross beam and can drive the support cross beam to move to indirectly drive the movement of the second edge 112 of the bed surface body 110.

[0049] It can be understood that the first support frame 200 can be erected on the ground or other bearing surfaces. The first support frame 200 is used to support the bed surface body 110 and can keep a certain distance between the bed surface body 110 and the ground or other bearing surfaces to prevent the moisture on the ground or other bearing surfaces from affecting the bed surface body 110.

[0050] It can be understood that the first wire tightening mechanism 300 is a structure for tightening objects such as wires. The first wire tightening mechanism 300 increases the tension of objects such as wires through a mechanical device. In some examples, the first wire tightening mechanism 300 rotates under an external force, can adjust the length of the first tension belt 120 and the tension of the first tension belt 120. The first tension belt 120 can drive the second edge 112 of the bed surface body 110 to approach or move away from the first edge 111, so that the distance between the first edge 111 and the second edge 112 can meet the user's needs. The second edge 112 can move away from the first edge 111 relatively to make the bed surface body 110 in a taut state. The second edge 112 can also approach the first edge 111 relatively to make the bed surface body 110 in a slightly relaxed state.

[0051] In the embodiment of the present application, the first support frame 200 of the camping bed 10 is arranged on one side of the bed surface assembly 100. The first support frame 200 can keep a certain distance between the bed surface body 110 and the ground or other bearing surfaces, so that the bed surface body 110 does not directly contact the ground or other bearing surfaces, which can avoid being affected by moisture. At the same time, the first wire tightening mechanism 300 rotates under the action of an external force and can adjust the length of the first tightening belt 120. The first wire tightening mechanism 300 can make the first tightening belt 120 drive the second edge 112 of the bed surface assembly 100 to approach or move away from the first edge 111. By adjusting the distance between the first edge 111 and the second edge 112, the first wire tightening mechanism 300 can tighten the bed surface body 110 with different widths, which not only improves the comfort of the camping bed 10 but also improves the adaptability of the camping bed 10.

[0052] Among them, in some examples, please refer to Figure 1 and please refer to Figure 2 , Figure 2 which is Figure 1 a partial enlarged schematic view of area A of the camping bed 10 shown in the figure. The first wire tightening mechanism 300 includes a fixed arm 310, a fixed arm slider 320, a movable arm 330, a movable arm slider 340, a roller 350 and a ratchet 360.

[0053] The fixed arm 310 can be connected to the other end of the first support frame 200, and the fixed arm 310 can also be connected to the second edge 112 of the bed surface assembly 100. The fixed arm slider 320 is connected to the fixed arm 310, and the fixed arm slider 320 can also be meshed and connected to the ratchet 360. The movable arm 330 is used to receive an external force. The movable arm slider 340 is connected to the movable arm 330, and the movable arm slider 340 can also be meshed and connected to the ratchet 360. The fixed arm 310, the movable arm 330 and the ratchet 360 are all sleeved on the end of the roller 350. The movable arm 330 is used to swing relative to the roller 350 under the action of an external force and drive the movable arm slider 340 to perform a ratchet movement relative to the ratchet 360. The roller 350 is connected to the first tightening belt 120. The first tightening belt 120 is sleeved on the outer surface of the roller 350 and can rotate relative to the roller 350 to wind or unwind.

[0054] It can be understood that when the fixed arm slider 320 and the movable arm slider 340 are respectively meshed and connected to the ratchet 360, the movable arm 330 is used to swing relative to the roller 350 and drive the movable arm slider 340 to move, and make the ratchet 360 and the roller 350 rotate in the first direction, so that the first tightening belt 120 drives the second edge 112 to move away from the first edge 111. The first tightening belt 120 winds relative to the roller 350, and the tension between the first edge 111 and the second edge 112 increases, and the bed surface body 110 is in a tightened state.

[0055] It can be understood that when the fixed arm slider 320 and the movable arm slider 340 are separated from the ratchet wheel 360 respectively, the roller 350 can rotate in a second direction opposite to the first direction, so that the first tension belt 120 drives the second edge 112 to approach the first edge 111. The first tension belt 120 unfolds relative to the roller 350, and the tension between the first edge 111 and the second edge 112 weakens, and the bed body 110 is in a relaxed state. Among them, the first direction can be the clockwise direction, and correspondingly, the second direction can be the counterclockwise direction, and vice versa.

[0056] It can be understood that the movable arm slider 340 and the fixed arm slider 320 can be ratchet pawl structures that cooperate with the ratchet wheel 360. The movable arm slider 340 and the fixed arm slider 320 can be respectively stuck in different tooth grooves of the ratchet wheel 360. The movable arm slider 340 can be used as the driving ratchet pawl of the ratchet wheel 360, and the fixed arm slider 320 can be used as the stopping ratchet pawl of the ratchet wheel 360. When the movable arm 330 swings in a certain direction, the movable arm slider 340 is inserted into the tooth groove of the ratchet wheel 360, pushing the ratchet wheel 360 to rotate a certain angle in the first direction, and then driving the roller 350 to tighten the first tension belt 120 connected thereto, realizing the winding of the first tension belt 120. When the movable arm 330 swings in the opposite direction, the fixed arm slider 320 can prevent the ratchet wheel 360 from rotating, while the movable arm slider 340 can slide over the tooth back of the ratchet wheel 360. Therefore, the ratchet wheel 360 remains stationary, and the ratchet wheel 360 realizes one-way movement.

[0057] It can be understood that the roller 350 can be a grooved roller structure. In this embodiment, a V-shaped groove or a U-shaped groove is provided on the roller 350. On the one hand, the grooved roller 350 can provide a stable guiding effect for the first tension belt 120, preventing the first tension belt 120 from shifting during rotation; on the other hand, the grooved roller 350 can also reduce the friction with the first tension belt 120, thereby extending the service life of the first tension belt 120.

[0058] It can be understood that the first wire tightening mechanism 300 of the present application can include two ratchet wheels 360, and the two ratchet wheels 360 are sleeved on two ends of the roller 350. Correspondingly, the fixed arm 310 and the movable arm 330 both include two connecting parts adapted to two ends of the roller 350, so that the movable arm 330 can more stably realize the movement of the roller 350.

[0059] It can be understood that, as Figure 2As shown, an unlocking groove 370 is further provided on the fixed arm 310. The unlocking groove 370 is adapted to the movable arm slider 340. A top convex structure 380 is further provided on the movable arm 330. The top convex structure 380 is adapted to the fixed arm slider 320. Among them, the movable arm slider 340 falls into the unlocking groove 370 and is limited and fixed. At this time, the movable arm slider 340 is separated from the ratchet wheel 360, and the two are separated from each other. Moreover, the top convex structure 380 can push the fixed arm slider 320 to separate from the ratchet wheel 360. When both the movable arm slider 340 and the fixed arm slider 320 are separated from the ratchet wheel 360, without the limitation of the movable arm slider 340 and the fixed arm slider 320, the roller 350 can rotate reversely, and then the first tension belt 120 can move reversely and be in a relaxed state.

[0060] In the first wire tightening mechanism 300 of the embodiment of the present application, with the mutual cooperation of the fixed arm 310, the fixed arm slider 320, the movable arm 330, the movable arm slider 340, the roller 350 and the ratchet wheel 360, the first wire tightening mechanism 300 can rotate unidirectionally and wind up the first tension belt 120. The first wire tightening mechanism 300 can not only tighten camping beds 10 of different lengths, improving the comfort of the camping bed 10, but also keep the camping bed 10 in a tightened state, improving the stability of the camping bed 10.

[0061] Among them, in some examples, please continue to refer to Figure 1 and Figure 2 , the camping bed 10 further includes a first support cross beam 410 and a second support cross beam 420. The first support cross beam 410 is connected to the first edge 111, the second support cross beam 420 is connected to the second edge 112, and the first tension belt 120 is connected to the second support cross beam 420. For example, the first tension belt 120 is sleeved on the outer surface of the second support cross beam 420, and the first tension belt 120 realizes the transmission connection with the second edge 112 of the bed surface body 110 through the second support cross beam 420.

[0062] It can be understood that the bed surface body 110 can be designed with a sleeve structure at the first edge 111 and the second edge 112, and the first support cross beam 410 and the second support cross beam 420 can penetrate into the sleeve structure, so that the bed surface body 110 is sleeved on the outer surfaces of the first support cross beam 410 and the second support cross beam 420 and forms the first edge 111 and the second edge 112.

[0063] It can be understood that the bed surface body 110 can be provided with a hollow structure in some areas of the sleeve structure. The first wire tightening mechanism 300 and the first tension belt 120 can be arranged corresponding to the hollow structure, and the first tension belt 120 can be connected to the second support cross beam 420 at the hollow structure.

[0064] In the embodiment of the present application, the camping bed 10 supports two edges of the bed surface body 110 through the first support cross beam 410 and the second support cross beam 420, which not only increases the structural strength of the bed surface body 110, but also makes it easier to tighten the bed surface body 110, thereby further improving the comfort of the camping bed 10.

[0065] Among them, in some examples, please refer to Figure 1 and please refer to Figure 3 , Figure 3 For Figure 1 a partial enlarged schematic view of another direction of area A of the camping bed 10 shown in the figure. The camping bed 10 further includes a limit clamp 510, which is sleeved on the outer surface of at least part of the second support cross beam 420 and is connected to the first support frame 200. The limit clamp 510 is used to limit the relative movement between the second support cross beam 420 and the first support frame 200.

[0066] It can be understood that the limit clamp 510 can be a semi-circular structure, and the two ends of the limit clamp 510 are spaced apart from each other to form an opening, and the second support cross beam 420 can be clamped into the inside of the limit clamp 510 through this opening.

[0067] The limit clamp 510 in the embodiment of the present application can limit the relative movement between the second support cross beam 420 and the first support frame 200 in the height direction of the camping bed 10, which can avoid the up and down shaking of the second edge 112 of the bed surface body 110 during the operation of the first wire tightening mechanism 300. The limit clamp 510 of the present application can improve the stability during the operation of the first wire tightening mechanism 300.

[0068] Among them, in some examples, please continue to refer to Figure 3 , the camping bed 10 further includes a guiding structure 520. One end of the guiding structure 520 is directly or indirectly connected to the second edge 112, and the other end of the guiding structure 520 is located between the second edge 112 and the first edge 111 and extends obliquely towards the end of the first support frame 200 away from the bed surface assembly 100. The guiding structure 520 can extend obliquely downwards, and the guiding structure 520 can provide a guiding effect for the bed surface body 110, making the tightening operation of the first wire tightening mechanism 300 on the bed surface body 110 smoother.

[0069] It can be understood that, in some examples, the limit clamp 510 is connected to one end of the guiding structure 520, and the limit clamp 510 and the guiding structure 520 are integrally formed structures. The integrally formed limit clamp 510 and guiding structure 520 can be formed by a single die-casting process, which greatly simplifies the production process.

[0070] It can be understood that the limiting clamp 510 is smoothly connected to one end of the guiding structure 520. At this time, the guiding path of the guiding structure 520 is longer, and the guiding effect of the guiding structure 520 is better; at the same time, the smooth transition between the two is not likely to have an adverse impact on the guiding operation of the guiding structure 520. The camping bed 10 of the present application is provided with the guiding structure 520. Under the action of gravity, the bed surface body 110 is prone to sag towards the direction where the first support frame 200 is located, and the inclined downward extending guiding mechanism can provide a guiding effect for the bed surface body 110, so that the camping bed 10 of the present application can gradually tighten and tense the bed surface body 110 under the action of the first wire tightening mechanism 300, and the camping bed 10 of the present application is more convenient to use.

[0071] It can be understood that the distance between the first edge 111 and the second edge 112 of the bed surface body 110 of the present application can be less than the maximum distance between the first edge 111 and the inner side wall of the limiting clamp 510, or rather, the depth of the limiting clamp 510 is greater than the thickness of the second support cross beam 420, and the limiting clamp 510 has a certain margin compared with the second support cross beam 420 and the bed surface body 110. Thus, even as the use time increases and the first tightening belt 120 is tightened more and becomes thicker, the limiting clamp 510 of the present application can still limit the bed surface body 110.

[0072] Among them, in some examples, please refer back to Figure 1 , the bed surface body 110 of the present application further includes a third edge 113 and a fourth edge 114 which are oppositely arranged, and the third edge 113 and the fourth edge 114 are located between the first edge 111 and the second edge 112; among them, the lengths of the first edge 111 and the second edge 112 are greater than the length of the third edge 113 or the fourth edge 114. The first edge 111 and the second edge 112 are the long sides of the bed surface body 110, and the third edge 113 and the fourth edge 114 are the short sides of the bed surface body 110. When one end of the first support frame 200 is connected to the first edge 111, the other end of the first support frame 200 is arranged on the side where the second edge 112 is located and is connected to the first wire tightening mechanism 300, and the first support frame 200 can extend along the short side direction of the bed surface body 110 and bear the bed surface body 110. At this time, the first wire tightening mechanism 300 tightens the bed surface body 110 along the short side direction of the bed surface body 110, and the acting distance of the first wire tightening mechanism 300 is shorter, and the first wire tightening mechanism 300 can better tense the bed surface body 110.

[0073] Among them, in other examples, please refer to Figure 4 , Figure 4This is the second structural schematic diagram of the camping bed 10 provided by the embodiments of the present application. In this example, the lengths of the first edge 111 and the second edge 112 of the bed surface body 110 are less than the lengths of the third edge 113 or the fourth edge 114. The first edge 111 and the second edge 112 are the short sides of the bed surface body 110, and the third edge 113 and the fourth edge 114 are the long sides of the bed surface body 110. When one end of the first support frame 200 is connected to the first edge 111, the other end of the first support frame 200 is arranged on the side where the second edge 112 is located and is connected to the first wire tightening mechanism 300. The first support frame 200 can extend along the long side direction of the bed surface body 110 and bear the bed surface body 110. Since the first wire tightening mechanism 300 tightens the bed surface body 110 through a one-way ratchet structure, thus, the first wire tightening mechanism 300 can have a longer acting distance to tighten the bed surface body 110; at the same time, the first support frame 200 bears the bed surface body 110 along the long side direction of the bed surface body 110, and the first support frame 200 can support a larger area of the bed surface body 110, so the stability of the camping bed 10 of the present application is better.

[0074] In some examples, the bed surface assembly 100 includes a plurality of first tension belts 120. The camping bed 10 can include a plurality of first support frames 200 and a plurality of first wire tightening mechanisms 300. The plurality of first support frames 200 are arranged at intervals along the extension direction of the first edge 111 or the second edge 112. The plurality of first wire tightening mechanisms 300 are respectively connected to the other ends of the plurality of first support frames 200 in one-to-one correspondence. The plurality of first wire tightening mechanisms 300 are also respectively connected to the plurality of first tension belts 120 in one-to-one correspondence. The plurality of first support frames 200 of the present application can better support the bed surface body 110 and the objects on the bed surface body 110, improving the stability of the camping bed 10; at the same time, the plurality of first wire tightening mechanisms 300 and the plurality of first tension belts 120 can provide greater tension for the bed surface assembly 100, further improving the comfort of the camping bed 10.

[0075] In some instances, such as Figure 4 and Figure 5 shown, Figure 5 is Figure 4Schematic structural diagram of the camping bed in another direction. The camping bed 10 of the present application may further include a second support frame 600 and a second wire tightening mechanism 700. The bed surface assembly 100 further includes a second tension belt 130, and the second tension belt 130 is connected to the fourth edge 114 of the bed surface body 110. Among them, the second support frame 600 and the first support frame 200 are located on the same side of the bed surface assembly 100, and one end of the second support frame 600 is connected to the third edge 113. The second wire tightening mechanism 700 is connected to the other end of the second support frame 600, and the second wire tightening mechanism 700 is also connected to the second tension belt 130. The second wire tightening mechanism 700 is used to rotate under an external force and adjust the length of the second tension belt 130, so that the second tension belt 130 drives the fourth edge 114 to approach or move away from the third edge 113.

[0076] It can be understood that the structure of the second support frame 600 can be the same as that of the first support frame 200. The structure of the second wire tightening mechanism 700 can be the same as that of the first wire tightening mechanism 300.

[0077] Under the action of the first wire tightening mechanism 300 and the second wire tightening mechanism 700, the camping bed 10 of the embodiment of the present application can not only tighten the first edge 111 and the second edge 112 of the bed surface body 110, but also tighten the third edge 113 and the fourth edge 114 of the bed surface body 110. The bed surface body 110 has greater tension and better comfort. At the same time, the bed surface body 110 is supported by the first support frame 200 spanning the first edge 111 and the second edge 112, and the second support frame 600 spanning the third edge 113 and the fourth edge 114. The support of the bed surface body 110 is better, further improving the comfort of the camping bed 10 of the present application.

[0078] In some examples, as Figure 1 and Figure 4 shown, the first support frame 200 includes a support base 210 and a support tube 220. The support base 210 includes a support leg frame 211 and a sleeve 212 connected to each other. The support tube 220 is connected to the first wire tightening mechanism 300, and the support tube 220 is sleeved in the sleeve 212 and connected to the sleeve 212. In the embodiment of the present application, the support tube 220 is sleeved in the sleeve 212 and connected, and the assembly of the entire first support frame 200 is simpler.

[0079] In some examples, the first support frame 200 further includes an elastic member, and the elastic member can be located in the support leg frame 211, the sleeve 212 and the support tube 220 to connect the support leg frame 211, the sleeve 212 and the support tube 220 in series. The entire first support frame 200 can be strung together by the elastic member, and the components of the first support frame 200 are not easily lost.

[0080] Based on the structure of the camping bed 10 described above, when assembling the camping bed 10 of the present application, the first support crossbeam 410 and the second support crossbeam 420 are connected to the bed surface assembly 100, the integral formed by the limit clamp 510 and the guiding structure 520 is connected to the second edge 112 of the bed surface assembly 100, the first wire tightening mechanism 300 is connected to the first tensioning belt 120, and the first wire tightening mechanism 300 is connected to the support pipe 220 of the first support frame 200; then, the support base 210 and the support pipe 220 of the first support frame 200 are assembled and connected, thus completing the assembly of the camping bed 10. Subsequently, by swinging the movable arm 330 of the first wire tightening mechanism 300, the roller 350 of the first wire tightening mechanism 300 drives the first tensioning belt 120 to wind up, so as to tighten the bed surface assembly 100. When it is necessary to disassemble the camping bed 10, the movable arm slider 340 disengages from the ratchet wheel 360 under the action of the unlocking groove 370, and the fixed arm slider 320 disengages from the ratchet wheel 360 under the action of the top convex structure 380. At this time, the roller 350 can rotate reversely and loosen the first tensioning belt 120. Subsequently, the connection between the support pipe 220 and the sleeve 212 is released. At this time, the bed surface assembly 100 and the connected first wire tightening mechanism 300 and support pipe 220 can be stored, and the support base 210 can also be stored.

[0081] Based on the above description, the first support frame 200 of the camping bed 10 of the present application can keep a certain distance between the bed surface body 110 and the ground or other bearing surfaces, avoiding the influence of moisture on the camping bed 10. At the same time, the first wire tightening mechanism 300 rotates under the action of an external force and can adjust the length of the first tightening belt 120 and the distance between the first edge 111 and the second edge 112 to tighten the bed surface body 110 of different widths, improving the comfort and adaptability of the camping bed 10. Moreover, the movable arm slider 340 of the first wire tightening mechanism 300 can disengage from the ratchet wheel 360 under the action of the unlocking groove 370, and the fixed arm slider 320 can also disengage from the ratchet wheel 360 under the action of the convex structure 380, so that the roller 350 can rotate reversely and loosen the first tightening belt 120 to relax the bed surface body 110, making the adjustment of the bed surface body 110 more flexible. And, the limit clamp 510 can improve the stability of the first wire tightening mechanism 300 during operation, and the guiding mechanism can provide a guiding effect for the bed surface body 110, making the tightening operation of the first wire tightening mechanism 300 on the bed surface body 110 smoother. At the same time, under the action of the first wire tightening mechanism 300, the first support frame 200 can be arranged along the long side of the camping bed 10 or along the short side of the camping bed 10, and the setting of the first support frame 200 is more flexible. Moreover, the support pipe 220 connected to the first wire tightening mechanism 300 can be sleeved in the sleeve 212 of the support base 210, and the connection mode between the support pipe 220 (and the structure connected thereto) and the sleeve 212 (and the structure connected thereto) is simpler, making the installation and disassembly of the camping bed 10 more convenient. And, the camping bed 10 can be tightened and supported under the combined action of the first wire tightening mechanism 300, the second wire tightening mechanism 700, the first support frame 200, and the second support frame 600, and the comfort of the camping bed 10 is better.
