Description

Technical Field

[0001] The utility model relates to the technical field of folding beds, in particular to an outdoor folding bed. Background Art

[0002] A folding bed is a bed frame that can be carried and stored portablely. Folding beds are generally designed using the principle of joints and can be folded and stored in various ways. Most folding bed frames on the market can meet the characteristics of folding and storage. Folding bed frames are generally used in hospitals, emergency rescue, outdoor camping and other occasions. Because many folding bed frames are used temporarily, many folding bed frames on the market are mostly designed with portability and storage in mind, without considering the user's comfort and the durability of the bed frame.

[0003] Patent CN220675623U discloses a three-section roll-up folding bed frame, which is provided with a bed head, a bed middle and a bed tail that can be rolled up and stretched out. A head support frame is provided at the bed head, and the head support frame is connected to the bed head through a head adjuster. The bed head can be adjusted relative to the head support frame. When the bed head is lowered, the head support frame can support the bed head, so that the bed head does not form a long-distance cantilever, which not only allows the user to adjust the head position, but also enhances the durability of the entire bed. Although the folding bed structure of this patent improves durability and user comfort, the folding and storage mechanism is too complicated, and a lot of connecting rod structures are used, which is inconvenient to use. Moreover, the entire bed structure cannot be separated when folded, resulting in excessive volume, which is not conducive to transportation, especially when used outdoors, and the convenience is not high.

[0027] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figure 1 to Figure 5As shown, the embodiment of the present application discloses an outdoor folding bed, including a bed frame 200, a support frame 100 and a support leg 13, the bed frame 200 includes multiple groups of support units horizontally laid on the support frame 100, and the multiple groups of support units are detachably connected, and at least one group of support units is fixedly connected to the support frame 100; both ends of the support frame 100 in the length direction are detachably connected with support legs 13, which are used to support the support frame 100 on the ground, and the support frame 100 can be folded and stored along its length direction. In this structure, the bed frame 200 includes a two-part structure, and the support frame 100 supported on the ground can be unfolded to a use state, and can also be folded and stored for easy carrying; in addition, the bed frame 200 connected to the upper end of the support frame 100 is also divided into multiple support units that can be detached from each other. When in use, it can be laid flat on the top of the support base frame. When stored, each support unit is disassembled into multiple independent units to reduce the volume and facilitate carrying; and in this structure, in order to ensure stability during use, at least one of the multiple support units is fixedly connected to the support base frame.

[0029] Preferably, in this embodiment, the plurality of support units include a head support unit 1, a back support unit 2, a hip support unit 3 and a leg support unit 4 which are sequentially arranged along the length direction of the bed frame 200, wherein the hip support unit 3 is fixedly connected to the support base frame, and any two adjacent support units are rotatably connected along the length direction of the bed frame 200 via a detachable pin 9; specifically, a first connection portion is provided on both sides of the rear end of the head support unit 1, and a second connection portion is provided on both sides of the front end of the back support unit 2, and the first connection portion, The second connection part is provided with a connecting through hole. When connecting, a pin shaft 9 of corresponding length is inserted into the connecting through hole, wherein one end of the pin shaft 9 is provided with a limiting cap with an area larger than the connecting through hole, and the other end is provided with a positioning socket penetrating along the radial direction thereof. After the connection is completed, a corresponding positioning plug rod is inserted into the positioning socket, and the pin shaft 9 is axially limited by the limiting cap and the positioning plug rod. When the head support unit 1 and the back support unit 2 need to be disassembled and stored, the positioning plug rod is pulled out first, and then the pin shaft 9 can be pulled out, and then the head support unit 1 and the back support unit 2 can be easily separated. In addition, the connection method between the back support unit 2 and the hip support unit 3, and the hip support unit 3 and the leg support unit 4 is the same as the connection method between the head support unit 1 and the back support unit 2, which will not be elaborated here.

[0030] In this embodiment, more specifically, a driving mechanism is connected to the hip support unit 3 for driving the head support unit 1, the back support unit 2 and the leg support unit 4 to rotate respectively. By adjusting the inclination angle of each support unit, the user's sleeping posture can be adjusted to improve comfort. In this structure, the angle adjustment of the head support unit 1, the back support unit 2 and the leg support unit 4 can be adjusted by only one support unit, or two support units, or all three support units; and the three support units can be adjusted independently or synchronously, which can be specifically controlled by a controller connected to the driving mechanism. In some other embodiments, the driving structure here can also be connected to the support base, or connected to the hip support unit 3 and the support base at the same time to ensure the connection strength.

[0031] In this embodiment, the structure in which all three support units are adjustable is used for explanation:

[0032] The driving mechanism includes a first electric push rod 5, a second electric push rod 6 and a third electric push rod 7, which are respectively used to drive the head support unit 1, the back support unit 2 and the leg support unit 4 to rotate; wherein one end of the first electric push rod 5 is hinged to the head support unit 1, and the other end is rotatably connected to the hip support unit 3 and is detachable from the same; one end of the second electric push rod 6 is hinged to the back support unit 2, and the other end is rotatably connected to the hip support unit 3 and is detachable from the same; one end of the third electric push rod 7 is hinged to the leg support unit 4, and the other end is rotatably connected to the hip support unit 3 and is detachable from the same.

[0033] In this structure, one end of the first electric push rod 5, the second electric push rod 6 and the third electric push rod 7 are connected to the hip support unit 3 by rotation through a detachable pin shaft 9. The purpose of this arrangement is that when the head support unit 1, the back support unit 2 and the leg support unit 4 are disassembled and stored with the hip support unit 3, each electric push rod can be stored synchronously.

[0034] In this embodiment, the end of the first electric push rod 5 away from the head support unit 1 is not directly connected to the hip support unit 3, but is indirectly connected; specifically, a mounting frame 8 is fixedly connected to the end of the back support unit 2 close to the hip support unit 3, the end of the second electric push rod 6 away from the hip support unit 3 is hinged to the mounting frame 8 through a detachable pin shaft 9, and the end of the first electric push rod 5 away from the head support unit 1 is hinged to the mounting frame 8 through a detachable pin shaft 9. This arrangement is to enable the second electric push rod 6 and the first electric push rod 5 to achieve a linkage effect during use, so that the support height adjustment of the head and back can be better coordinated and the comfort is improved.

[0035] See attached Figure 3In this embodiment, the support frame 100 includes a first frame 10, a second frame 11 and a third frame 12 which are sequentially connected along the length direction of the bed frame 200, the hip support unit 3 is fixedly connected to the second frame 11, one end of the second frame 11 and the third frame 12 are rotatably connected to the two ends of the second frame 11 respectively, and the second frame 11 and the third frame 12 can be folded down and stored; the other ends of the second frame 11 and the third frame 12 are detachably connected with support feet 13.

[0036] For more details, see the attached Figure 3 , 4 The first frame 10 includes two first cross bars 14 arranged in parallel along the width direction of the bed frame 200, the second frame 11 includes two second cross bars 15 arranged in parallel along the width direction of the bed frame 200, and the third frame 12 includes two third cross bars 16 arranged in parallel along the width direction of the bed frame 200; the two ends of the two second cross bars 15 are rotatably connected to one end of the two first cross bars 14 and the third cross bars 16 respectively, and the two ends of the hip support unit 3 are respectively connected to the upper ends of the two second cross bars 15; the other ends of the two first cross bars 14 are detachably connected with a first longitudinal bar 17, and The two ends of the first longitudinal rod 17 are connected to the supporting feet 13 respectively; specifically, the two ends of the first longitudinal rod 17 are connected to the first connecting rod 22 for inserting into the first receiving groove, and the first connecting rod 22 is connected to the first cross bar 14 by a detachable pin 9; in addition, the other ends of the two third cross bars 16 are detachably connected to the second longitudinal rod 18, and the two ends of the second longitudinal rod 18 are respectively connected to the supporting feet 13. In this structure, the connection method between the second longitudinal rod 18 and the third cross bar 16 is the same as the connection method between the first longitudinal rod 17 and the first cross bar 14, which will not be repeated here. In the above structure, in order to further reduce the packaging volume after disassembly, the four supporting feet 13 are also detachably connected to the corresponding longitudinal rods by threaded matching.

[0037] For details, please refer to the attached Figure 4The first cross bar 14 and the third cross bar 16 are both square tubes with openings at the bottom to form a first accommodating groove and a second accommodating groove respectively. The width of the first accommodating groove is greater than the width of the second cross bar 15 and less than the width of the second accommodating groove, that is, the second cross bar 15 can be received in the first cross bar 14, and the first cross bar 14 can be received in the third cross bar 16; the top walls of the first cross bar 14 and the third cross bar 16 near one end of the second cross bar 15 are provided with open positioning grooves 19, and the two ends of the second cross bar 15 are respectively rotatably matched with the first cross bar 14 and the third cross bar 16; when the bed frame 200 is in the open use state, the two end surfaces of each second cross bar 15 are respectively in contact with the bottom of the two corresponding open positioning grooves 19 to achieve anti-rotation limit; in the folded storage state, the first cross bar 14 and the third cross bar 16 are respectively turned down and stored until the second cross bar 15 is stored in the first storage groove, and the first cross bar 14 is stored in the second storage groove, that is, the length of the three cross bars is folded into the length of one support rod 21, and the support rods 21 are nested and stored with each other, see the attached Figure 5 (The supporting feet 13 and the two longitudinal rods are not shown).

[0038] That is, when the bed is deployed and used between the first frame 10, the second frame 11 and the third frame 12, the two end surfaces of the two second cross bars 15 are respectively abutted against the bottom of the corresponding positioning grooves to achieve horizontal support and limitation. In this way, there is no need to set support feet 13 in the middle position of the support base. Instead, the force and load are borne by abutting the connecting pins 9 and the end surfaces between the second frame 11 and the first frame 10 and the third frame 12, thereby simplifying the bed structure, reducing the overall weight, and making it convenient to carry during travel.

[0039] In this embodiment, see the attached Figure 1 Each support unit includes a support frame assembled from a plurality of hollow square tubes, and a steel wire 20 is welded on the upper end surface of each support frame to form a support plane. The welded steel wire 20 replaces the bed plate structure, further simplifying the bed structure.

[0040] In addition, see Appendix Figure 1 Yes, a storage box 23 and a power box 24 for placing energy storage batteries are also connected to the lower end of the support frame 100, wherein the energy storage batteries are used to power each electric push rod. Of course, each electric push rod involved in this embodiment is equipped with a rechargeable battery. When the power is low, the energy storage battery is used for temporary power supply.

[0041] In this embodiment, see the attached Figure 2It can be seen that the leg support unit 4 includes a thigh support part and a calf support part, and the thigh support part and the calf support part are also rotatably connected via a detachable pin 9; in addition, it can be seen from the figure that the outer end of the calf support part obviously protrudes beyond the outer ends of the second longitudinal rod 18 and the third cross rod 16. In order to ensure the structural strength of the calf support part, two spaced support rods 21 are rotatably connected to the lower end surface of the outer end thereof via a detachable pin 9, and the other ends of the two support rods 21 are rotatably connected to the second longitudinal rod 18 via a detachable pin 9. This structure effectively increases the structural strength of the calf support part and is convenient for disassembly and assembly.
