DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods. Directional words such as up, down, left, right, and the words "first", "second", "third" and "fourth" described in the present invention are only used to better explain the present invention, but are not used to limit the present invention.

[0031] The present invention provides a folding bed, comprising a plurality of bed leg assemblies 1, a bed surface 2, a bed surface tube assembly and a longitudinal folding assembly, wherein the bed surface tube assembly comprises two bed surface tubes 3, and the left and right sides of the bed surface 2 are provided with hanging ears, and the two bed surface tubes 3 respectively pass through the hanging ears on both sides and are arranged on both sides of the bed surface 2; the longitudinal folding assembly is connected between two adjacent bed leg assemblies 1;

[0032] The bed leg assembly 1 comprises a first bracket 11, a second bracket 12, a first support rod 13, a second support rod 14, a first connecting bar 15 and a second connecting bar 16; the top ends of the first bracket 11 and the second bracket 12 are detachably connected to the bed surface pipe assembly respectively, and the bed leg assembly 1 is arranged at intervals;

[0033] One end of the first support rod 13 is hinged to the upper end of the first bracket 11, and the other end is hinged to one end of the first connecting strip 15, and the other end of the first connecting strip 15 is hinged to the lower end of the second bracket 12; one end of the second support rod 14 is hinged to the upper end of the second bracket 12, and the other end is hinged to one end of the second connecting strip 16, and the other end of the second connecting strip 16 is hinged to the lower end of the first bracket 11;

[0034] The middle portion of the first support rod 13 is hinged to the middle portion of the second support rod 14 .

[0035] Please refer to Figure 1 and Figure 2 The bed surface tube assembly includes two bed surface tubes 3, which are detachably connected to the bed leg assembly 1, respectively, and can further reduce the volume of the folded bed, making the folding bed more compact and lightweight, and suitable for carrying. The bed surface tubes 3 are arranged on both sides of the bed surface 2. When the bed surface tube assembly is connected to the bed leg assembly 1, the shape of the bed surface 2 can be supported, so that the bed surface 2 can be fully unfolded and not easily collapsed, providing sufficient space for users. In a specific embodiment, the left and right sides of the bed surface 2 are provided with hanging ears, and the two bed surface tubes 3 pass through the hanging ears on both sides respectively to realize the connection between the bed surface tubes 3 and the bed surface 2;

[0036] Please refer to Figure 4When unfolding the folding bed, opposite pulling forces can be applied to the first bracket 11 and the second bracket 12 respectively, so that the distance between the first bracket 11 and the second bracket 12 is increased, thereby driving the first support rod 13, so that the first support rod 13 rotates upward with the upper end of the first bracket 11 as the center of the circle; the first connecting bar 15 is pulled by the first support rod 13 and rotates upward with the lower end of the second bracket 12 as the center of the circle; similarly, the second support rod 14 is also driven to rotate upward with the upper end of the second bracket 12 as the center of the circle; the second connecting bar 16 is pulled by the second support rod 14 and rotates upward with the lower end of the first bracket 11 as the center of the circle. The first connecting bar 15 and the second connecting bar 16 respectively limit the rotation limit of the first support rod 13 and the second bracket 12, so as to prevent the first support rod 13 and the second bracket 12 from continuing to open outward under the force, thereby destroying the stability of the folding bed.

[0037] The other end of the first support rod 13 and the other end of the second bracket 12 are respectively against the ground, and cooperate with the first bracket 11 and the second bracket 12 to achieve self-locking through gravity, the first connecting strip 15 and the second connecting strip 16, so that the bed leg assembly 1 is unfolded into a stable structure. At the same time, the two bed surface tubes 3 pass through the hanging ears on the left and right sides respectively, and are connected to the top of the first bracket 11 and the second bracket 12 respectively; when the two bed surface tubes 3 are connected to the bed leg assembly 1, the bed surface 2 is supported, and several groups of bed leg assemblies 1 are equidistantly connected in series, and cooperate with the longitudinal folding assembly to form a stable folding bed structure.

[0038] When the folding bed is folded, thrusts in opposite directions can be applied to the first bracket 11 and the second bracket 12 respectively, so that the distance between the first bracket 11 and the second bracket 12 is reduced, and the first support rod 13 is rotated downward with the upper end of the first bracket 11 as the center; the first connecting bar 15 is driven to rotate downward with the lower end of the second bracket 12 as the center; at the same time, the second support rod 14 is rotated downward with the upper end of the second bracket 12 as the center; the second connecting bar 16 is rotated downward with the lower end of the first bracket 11 as the center; the various components of the bed leg assembly 1 are collected and gathered into a very small volume, which is convenient for transportation and carrying.

[0039] Since the folding bed has a certain length, a plurality of bed leg assemblies 1 are provided in the folding bed, and the number of bed leg assemblies 1 can be selected according to actual conditions. The bed leg assemblies 1 are arranged at intervals so that the folding bed is evenly stressed, and the weight is evenly distributed to the first bracket 11 and the second bracket 12 in each bed leg assembly 1 through the conduction of the bed surface pipe assembly, thereby enhancing the stability of the folding bed after being unfolded.

[0040] The length direction of the folding bed is the longitudinal direction, and the width direction of the folding bed is the transverse direction. The first longitudinal folding assembly 4 and the second longitudinal folding assembly 5 connect the adjacent bed leg assemblies 1. When the folding bed is unfolded, as long as a transverse force is applied to any one of the first brackets 11 and the second bracket 12, the longitudinal folding assembly can transmit the transverse force to the first brackets 11 and the second brackets 12 of the other bed leg assemblies 1, so that the bed leg assemblies 1 can be unfolded synchronously, so that a single person can easily unfold or fold the folding bed.

[0041] In a specific embodiment, there are four groups of bed leg assemblies 1, two of which are respectively arranged at the two ends of the bed surface tube assembly, and the other two groups of bed leg assemblies 1 are respectively arranged in the middle of the bed surface tube assembly. The folding vehicle has four groups of bed leg assemblies 1, which not only meets the stability requirements of the folding bed after unfolding, but also avoids the increase of the overall weight due to too many bed leg assemblies 1, which increases the production cost.

[0042] Furthermore, the bed surface tube 3 includes a first tube section 31, a second tube section 32 and a third tube section 33; a first embedded sleeve 34 is provided at one end of the first tube section 31, and a second embedded sleeve 35 is provided at one end of the second tube section 32;

[0043] The other end of the second pipe section 32 is embedded in the first embedding sleeve 34 , and one end of the third pipe section 33 is embedded in the second embedding sleeve 35 .

[0044] Furthermore, the two sets of bed leg assemblies 1 located in the middle are respectively arranged at the first embedded sleeve 34 and the second embedded sleeve 35. Since the folding bed has a certain length, the length of the bed surface pipe assembly is also correspondingly long. After folding, the bed surface pipe assembly is not convenient to carry. Therefore, the bed surface pipe assembly is divided into three interlocking pipe sections, which can make it more compact when folded, suitable for carrying when going out for picnics and camping.

[0045] The bed leg assembly 1 is arranged in four groups. When the bed leg assembly 1 is supported on the first embedded sleeve 34 / the second embedded sleeve 35, the upper end of the first bracket 11 / the second bracket 12 can apply an upward supporting force to the first embedded sleeve 34 / the second embedded sleeve 35, and the first embedded sleeve 34 / the second embedded sleeve 35 transmits the supporting force to the ends of the first pipe segment 31 and the second pipe segment 32 / the second pipe segment 32 and the third pipe segment 33 through the inner wall, so that the first bracket 11 / the second bracket 12 can simultaneously support the ends of the first pipe segment 31 and the second pipe segment 32 / the second pipe segment 32 and the third pipe segment 33, so that the folding bed is more stable when unfolded.

[0046] Furthermore, the longitudinal folding component includes a first longitudinal folding component 4 and a second longitudinal folding component 5 , wherein both ends of the first longitudinal folding component 4 are respectively hinged to the adjacent first bracket 11 , and both ends of the second longitudinal folding component 5 are respectively hinged to the adjacent second bracket 12 .

[0047] The length direction of the folding bed is longitudinal, and the width direction of the folding bed is transverse. The first longitudinal folding assembly 4 and the second longitudinal folding assembly 5 connect the adjacent bed leg assemblies 1. When the folding bed is unfolded, as long as a transverse force is applied to any one of the first brackets 11 and the second bracket 12, the first longitudinal folding assembly 4 and the second longitudinal folding assembly 5 can transmit the transverse force to the first brackets 11 and the second brackets 12 of the other bed leg assemblies 1, so that the bed leg assemblies 1 can be unfolded synchronously, so that a single person can easily unfold or fold the folding bed; moreover, the first longitudinal folding assembly 4 and the second longitudinal folding assembly 5 cooperate with the bed leg assembly 1 to realize the folding of the folding bed in the transverse direction and the longitudinal direction, so that the volume is further reduced.

[0048] For further information, please refer to Figure 2 , the first longitudinal folding assembly 4 includes a first oblique rod 41, a second oblique rod 42, a first guide bar 43 and a second guide bar 44;

[0049] One end of the first oblique rod 41 is hinged to the upper end of the first bracket 11, and the side surface of the other end is hinged to one end of the first guide bar 43, and the other end of the first guide bar 43 is hinged to the lower end of another adjacent first bracket 11;

[0050] One end of the second diagonal rod 42 is hinged to the upper end of another adjacent first bracket 11, and the side surface of the other end is hinged to one end of the second guide bar 44, and the other end of the second guide bar 44 is hinged to the lower end of the first bracket 11; the middle part of the first diagonal rod 41 is hinged to the middle part of the second diagonal rod 42.

[0051] Further, the second longitudinal folding assembly 5 includes a third oblique rod 51, a fourth oblique rod 52, a third guide bar 53 and a fourth guide bar 54;

[0052] One end of the third oblique rod 51 is hinged to the upper end of the second bracket 12, and the side surface of the other end is hinged to one end of the third guide bar 53, and the other end of the third guide bar 53 is hinged to the lower end of another adjacent second bracket 12;

[0053] One end of the fourth diagonal rod 52 is hinged to the upper end of another adjacent second bracket 12, and the side surface of the other end is hinged to one end of the fourth guide bar 54, and the other end of the fourth guide bar 54 is hinged to the lower end of the second bracket 12; the middle part of the third diagonal rod 51 is hinged to the middle part of the fourth diagonal rod 52.

[0054] Please refer to Figure 3 In the specific embodiment, the first longitudinal folding assembly 4 and the second longitudinal folding assembly 5 have the same structure and the same folding method. In addition, during the unfolding or folding process, a force is applied to the adjacent first bracket 11 or second bracket 12, and the first longitudinal folding assembly 4 and the second longitudinal folding assembly 5 are both subjected to the force transmitted by the bed leg assembly 1, and unfold or fold at the same time. Therefore, the unfolding and folding process of the first longitudinal folding assembly 4 is used as an example for explanation.

[0055] When the first longitudinal folding component 4 is unfolded, a pulling force in opposite longitudinal directions is applied to one first bracket 11 and another first bracket 11, so that the distance between the two adjacent first brackets 11 increases; thereby driving the first oblique rod 41 to rotate upward with the upper end of the first bracket 11 as the center; the first guide bar 43 is pulled by the first oblique rod 41 and rotates upward with the lower end of the other adjacent first bracket 11 as the center; similarly, the second oblique rod 42 rotates upward with the upper end of the other adjacent first bracket 11 as the center; the second guide bar 44 is pulled by the second oblique rod 42 and rotates upward with the lower end of the first bracket 11 as the center. When the first longitudinal folding component 4 is folded, the first oblique rod 41, the second oblique rod 42, the first guide bar 43 and the second guide bar 44 rotate downward respectively with the center of the first longitudinal folding component 4 when it is unfolded, which will not be described in detail here.

[0056] The first guide bar 43 and the second guide bar 44 respectively limit the rotation limit of the first oblique rod 41 and the second oblique rod 42 to prevent the first oblique rod 41 and the second oblique rod 42 from continuing to open outward and destroying the stability of the first longitudinal folding assembly 4. The adjacent first bracket 11, the first oblique rod 41 and the second oblique rod 42 form a stable structure, and self-locking is achieved through gravity, the first guide bar 43 and the second guide bar 44.

[0057] Please refer to Figure 4 Specifically, the other ends of the first support rod 13 and the second support rod 14 are respectively extended with a support portion 112, and the first support rod 13 and the second support rod 14 are both in a "J" shape. The other ends of the first support rod 13 and the second support rod 14 are respectively in contact with the ground, and the support portion 112 is the fulcrum of the bottom of the folding bed. Therefore, the support portion 112 increases the contact area between the bottom of the folding bed and the ground, reduces the influence of the outdoor ground on the stability of the folding bed, and makes the folding bed more stable after unfolding.

[0058] In a specific embodiment, the tops of the first bracket 11 and the second bracket 12 are both provided with a fixing groove 111, and the fixing groove 111 is adapted to the bed surface tube 3, and the bed surface tube 3 is embedded in the fixing groove 111. The first bracket 11 and the second bracket 12 are both connected to the bed surface tube 3 through the fixing groove 111, which can simplify the operation of unfolding or folding, and a single person can unfold or fold the folding bed.

[0059] Preferably, the bed leg assembly 1 and the bed surface tube assembly are made of aluminum alloy, and the bed surface 2 is made of canvas material. The use of aluminum alloy can prevent rust without reducing the strength of the bed leg assembly 1 and the bed surface tube assembly, and the bed surface 2 made of canvas material is not only comfortable to sleep on, but also easy to fold.

[0060] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific embodiments of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
