[0030] ReferenceFigures 1 to 8 In an embodiment of the utility model, a bed sleep-aiding table comprises:

[0031] The folding plate assembly comprises a top plate 100, side plates 200 and a plurality of hinge pieces 300. The two side plates 200 are respectively hinged to the lower ends of the length direction of the top plate 100 through the plurality of hinge pieces 300 to be folded inward and outward in the length direction of the top plate 100. The top plate 100 comprises a top plate sound-absorbing layer 110 arranged in the lower layer and a top plate sound-insulating board 120 arranged in the upper layer. The side plate 200 comprises a side plate sound-absorbing layer 210 arranged in the inner layer and a side plate sound-insulating board 220 arranged in the outer layer. When the side plate 200 is folded outward, the length direction of the side plate 200 is 90-120 degrees to the length direction of the top plate 100 to support the top plate 100 horizontally.

[0032] The end plate 400 is arranged in the detachable mode at one end of the width direction of the folding plate assembly. The end plate 400 comprises an end plate sound-absorbing layer arranged in the inner layer and an end plate sound-insulating board arranged in the outer layer. When the end plate 400 is combined with the folding plate assembly in the outward folding state, the end plate 400 closes one end of the width direction of the folding plate assembly.

[0033] In the prior art, the sound wave frequency range of snoring noise, tooth grinding noise and mobile phone noise ranges from low frequency to high frequency, so it is difficult to process noise. It is difficult to process noise in a certain way while ensuring the noise processing effect and reducing the inconvenience to the user.

[0034] In the utility model, the bed sleep-aiding table comprises a folding plate assembly and an end plate 400. The folding plate assembly comprises a top plate 100, side plates 200 and a plurality of hinge pieces 300. The shape of the hinge piece 300 can be various, and the specific shape is not limited. The two side plates 200 are respectively hinged to the lower ends of the length direction of the top plate 100 through the plurality of hinge pieces 300 to be folded inward and outward in the length direction of the top plate 100. The two side plates 200 are arranged opposite to each other on the top plate 100, but the shape and arrangement are not limited to be completely consistent. When the side plate 200 is folded inward, the occupied volume of the entire folding plate assembly is reduced, which is convenient for storage, transportation and storage. When the side plate 200 is folded outward, the folding plate assembly can be used as a table body on the bed. The length of the side plate 200 is about 70 cm, and the length of the top plate 100 matches the width of the bed body, for example, about 90 cm. The two side plates 200 are not limited to be flat structures or completely consistent structures, and can be adaptively adjusted for the convenience of storage in some cases.

[0035] The end plate 400 is detachably arranged at one end of the folding plate assembly in the width direction. The end plate 400 is arranged at the head of the bed, and no connection is required between the end plate 400 and the folding plate assembly during non-sleeping use. When the end plate 400 is combined with the folding plate assembly in the everted state, the end plate 400 encloses the folding plate assembly to form a sound-absorbing space (the user's head is also placed in the sound-absorbing space), which can effectively reduce the emission of noise from the user's head. The corresponding mode between the end plate 400 and the folding plate assembly can be a form of pressing or resisting without forming a connection, or a separable fixed connection (such as clamping, buckling, magnetic connection, or plug-in connection, etc.).

[0036] The end plate 400 includes an end plate sound-absorbing layer arranged inside and an end plate sound-insulating board arranged outside. The top plate 100 includes a top plate sound-absorbing layer 110 arranged below and a top plate sound-insulating board 120 arranged above. The side plate 200 includes a side plate sound-absorbing layer 210 arranged inside and a side plate sound-insulating board 220 arranged outside. That is, the outer periphery of the sound-absorbing space is wrapped by the sound-absorbing layer, and at this time, the noise emitted from the head position is preferentially partially absorbed by the end plate sound-absorbing layer, the top plate sound-absorbing layer 110, and the side plate sound-absorbing layer 220; while the end plate sound-insulating board, the top plate sound-insulating board 120, and the side plate sound-insulating board 220 produce sound-insulating effects, they also reflect the noise that has not been absorbed back to the direction of the sound-absorbing space, which is then absorbed again. The materials of the top plate sound-absorbing layer 110, the side plate sound-absorbing layer 210, and the end plate sound-absorbing layer can be sound-absorbing cotton or sound-absorbing blanket, and the density or porosity of the specific material is selected according to actual use. In some cases, the top plate sound-absorbing layer 110, the side plate sound-absorbing layer 210, and the end plate sound-absorbing layer can also be in the form of an assembly, for example, a porous sound-absorbing material (sound-absorbing cotton or sound-absorbing blanket, etc.) is wrapped with a porous cloth to form an assembly, thereby forming superior assembly and appearance effects under the condition of having sound-absorbing performance.

[0037] The materials of the top plate sound-insulating board 120, the side plate sound-insulating board 220, and the end plate sound-insulating board are set to be high polymer or solid wood to reduce the generation of harmful gases. During use, the noise generator and the noise interfered person use the bed with the sleep-aiding table at the same time, which can achieve more superior effects.

[0038] After the side plate 200 is everted, the length direction is 90 to 120 degrees with respect to the length direction of the top plate 100, so that the side plate 200 can form a better support effect. The side plate 200 and the top plate 100 are not limited to straight plates, and the length direction is referenced for the angle.

[0039] The material of the top plate sound-absorbing layer 110, the side plate sound-absorbing layer 210 and the end plate sound-absorbing layer is sound-absorbing blanket or sound-absorbing cotton; the material of the top plate sound-insulating board 120, the side plate sound-insulating board 220 and the end plate sound-insulating board is high polymer or solid wood. The density or porosity of the two specific materials of the top plate sound-absorbing layer 110, the side plate sound-absorbing layer 210 and the end plate sound-absorbing layer is selected according to actual use. Since the sleep-aiding table for bed is used in the sound insulation function and the use position is the head of the user, the use of glue should be cautious during the processing of the sleep-aiding table for bed, and the material of the top plate sound-insulating board 120, the side plate sound-insulating board 220 and the end plate sound-insulating board is set to high polymer or solid wood to reduce the generation of harmful gas.

[0040] In a test process, the end plate sound-absorbing layer, the top plate sound-absorbing layer 110 and the side plate sound-insulating board 220 are 2 cm thick sound-absorbing cotton; the end plate sound-absorbing layer, the top plate sound-absorbing layer 110 and the side plate sound-insulating board 220 are 1 cm thick wood board, the noise source test is 61.1 decibels, the sound level meter is 50 cm away from the position of the noise source, and the test result of the sound level meter is 60.3 decibels. After the sleep-aiding table for bed is assembled, it is placed on the noise source, and at this time the test data of the sound level meter is 50.8 decibels. After a sleep-aiding table for bed is also placed on the sound level meter, the test result of the sound level meter is 47.7 decibels. The above test results show that the sleep-aiding table for bed has excellent insertion loss.

[0041] In summary, when the side plate 200 is turned inward, the occupied volume of the entire folding plate assembly is reduced, which is convenient for storage, transportation and storage; when the side plate 200 is turned outward, the folding plate assembly can be used as a table body on the bed; when the end plate 400 is combined with the folding plate assembly in the turned-out state, the end plate 400 closes the folding plate assembly, thereby forming a sound-absorbing space, and the outer periphery of the sound-absorbing space is wrapped by the sound-absorbing layer. At this time, the noise emitted at the head position is preferentially partially absorbed by the end plate sound-absorbing layer, the top plate sound-absorbing layer 110 and the side plate sound-insulating board 220; while the end plate sound-insulating board, the top plate sound-insulating board 120 and the side plate sound-insulating board 220 produce a sound insulation effect, the noise that is not absorbed is also reflected back to the direction of the sound-absorbing space and is absorbed again.

[0042] Reference Figures 7 to 8 In an embodiment, the hinge shafts of the hinges 300 corresponding to the two side plates 200 form a height difference in the thickness direction of the top plate 100.

[0043] Generally, the side plates 200 are flat plates, so that the two side plates 200 cannot be well accommodated after being turned inward, for example, when one side plate 200 is attached to the lower surface of the top plate 100, the other side plate 200 is turned inward and is lifted by the other side plate 200 due to the occupied position, so that the two side plates 200 cannot be stacked. In the embodiment, the corresponding two side plates 200 are provided with the hinge members 300, so that the hinge shafts of the hinge members 300 on both sides of the top plate 100 form a height difference, so that the two side plates 200 can be stacked after being turned inward. In the case that one end of the side plate 200 in the length direction is connected with the hinge member 300, the length of the side plate 200 needs to be adaptively designed, so that the two side plates 200 can still support the top plate 100 horizontally in the case that the hinge shafts of the hinge members 300 form a height difference. If the lengths of the two side plates 200 are consistent, the connection positions of the two side plates 200 with the hinge members 300 need to be adaptively adjusted, so that the two side plates 200 can support the top plate 100 horizontally after being turned outward.

[0044] The height difference of the hinge shafts of the hinge members 300 on both sides can be achieved in various ways, for example, a boss 130 is provided on one side of the lower surface of the top plate 100, and the sizes of all the hinge members 300 are consistent, so that the heights of the hinge members 300 on both sides of the top plate 100 naturally form a difference when the hinge member 300 on one side is fixed to the boss 130 (the boss 130 and the top plate 100 can be an integral structure or a connected structure). Alternatively, the structures of the hinge members 300 on both sides of the top plate 100 are different, so that the hinge shafts of the hinge members 300 on both sides of the top plate 100 naturally form a height difference after all the hinge members 300 are installed.

[0045] Referring to Figure 6 In one embodiment, one end of the top plate 100 in the width direction is provided with a shielding curtain 500 in the length direction, wherein the height of the shielding curtain 500 is one fourth to three fourths of the height of the side plate 200.

[0046] In the embodiment, when the end plate 400 is combined with the folded plate assembly in the outward turned state, the end plate 400 closes one end of the folded plate assembly in the width direction, and the other end of the folded plate assembly is open, so that the noise treatment effect is not good. The shielding curtain 500 can further limit the noise in the bed sleep-aiding table. If the height of the shielding curtain 500 is too short, the noise closing effect is not good, and if the height of the shielding curtain 500 is too long, the user's breathing is not good and a depressed feeling is easily generated. The shielding curtain 500 can be a fiber woven material or a film material.

[0047] Referring to Figures 1 to 5 In one embodiment, the side plate 200 is turned outward in the length direction, and the angle between the length direction of the side plate 200 and the length direction of the top plate 100 is 100 to 110 degrees.

[0048] In the embodiment, the working angle of the side plate 200 is further limited to 100-110 degrees. When the side plate 200 is used as a table plate by being turned outwards, the possibility of the side plate 200 being turned inwards accidentally is reduced if the maximum turning-out angle exceeds 90 degrees, and the length of the side plate 200 and the space occupied by the whole folding plate assembly in the length direction are reduced.

[0049] In an embodiment, the side plate 200 is in abutment with the top plate 100 when it is turned outwards.

[0050] In the embodiment, the angle limitation of the side plate 200 is achieved by the abutment between the side plate 200 and the top plate 100 when the side plate 200 is turned outwards. Specifically, the end of the side plate 200 close to the top plate 100 is shaped, and when the side plate 200 is turned outwards to the limit angle, the side plate 200 is in abutment with the top plate 100, and the side plate 200 cannot be turned outwards any more.

[0051] Referring to Figures 2 to 3 In an embodiment, the top plate sound-absorbing layer 110 and the top plate sound-insulating plate 120 are fixed in the thickness direction, the side plate sound-absorbing layer 210 and the side plate sound-insulating plate 220 are fixed in the thickness direction, and the end plate sound-absorbing layer and the end plate sound-insulating plate are fixed in the thickness direction.

[0052] Because the head of the user is in the use position in the sound insulation function of the sleep-aiding table for bed, the use of glue in the processing of the sleep-aiding table for bed should be cautious. In the embodiment, the fixing of the top plate sound-absorbing layer 110 and the top plate sound-insulating plate 120 is taken as an example, and a side strip fixing member 600 is introduced, which is installed on the top plate 100 in the thickness direction, so that the side strip fixing member 600 fixes the top plate sound-absorbing layer 110 and the top plate sound-insulating plate 120 in the thickness direction of the whole top plate 100. The introduction of the side strip fixing member 600 has the effect of edge covering and fixes the top plate sound-absorbing layer 110 and the top plate sound-insulating plate 120.

[0053] In an embodiment, the hinge member 300 is connected to the top plate 100 and the side plate 200 by a plurality of fixing nails, wherein the fixing nails on the top plate 100 fix the top plate sound-absorbing layer 110 to the top plate sound-insulating plate 120, and the fixing nails on the side plate 200 fix the side plate sound-absorbing layer 210 to the side plate sound-insulating plate 220.

[0054] In the embodiment, the fixing of the top plate sound-absorbing layer 110 and the side plate sound-absorbing layer 210 is achieved by the installation process of the hinge member 300, which reduces the processing difficulty and also makes the fixing process of the top plate sound-absorbing layer 110 and the side plate sound-absorbing layer 210 not introduce related harmful substances.

[0055] Referring to Figures 1 to 5 In one embodiment, the top plate 100 is consistent with the width of the side plate 200 and is arranged in alignment in the width direction.

[0056] In the present embodiment, the width of the top plate 100 is consistent with that of the side plate 200, which is convenient for processing, and the top plate 100 and the side plate 200 can be aligned in the width direction, and the process of forming a seal between the end plate 400 and the folding plate assembly is simpler. For example, if the top plate 100 and the side plate 200 are not aligned in the width direction, the shape of the end plate 400 may need to be designed accordingly to meet the sealing requirements.

[0057] In one embodiment, two to three hinge members 300 are arranged on the side plate 200 in the width direction.

[0058] In the present embodiment, the number of hinge members 300 used to lift the fixed side plate 200 is increased, so that the side plate 200 can be better fixed and can be more smoothly turned over. During the fixing process of the hinge member 300, the sound-absorbing layer 110 of the top plate can be fixed to the sound-insulating plate 120 of the top plate, and the sound-absorbing layer 210 of the side plate can be fixed to the sound-insulating plate 220 of the side plate. In some embodiments, the length of a single hinge member 300 is increased, so that the side plate 200 can be fixed with a higher degree of fixation using only one hinge member 300.

[0059] In one embodiment, the end plate 400 and the folding plate assembly are connected by one of clamping, buckling, magnetic connection or insertion.

[0060] In some embodiments, the corresponding mode between the end plate 400 and the folding plate assembly can be pressed or resisted without forming a connection. In the present embodiment, the end plate 400 and the folding plate assembly can form a connection, thereby improving the stability of the cooperation between the two. Specifically, the connection mode between the end plate 400 and the folding plate assembly can be clamping, buckling, magnetic connection or insertion, etc., without being specially limited, and common modes in the prior art are referred to.

[0061] In one embodiment, the end plate 400 is provided with a fixing member for connecting with an external bed structure.

[0062] Due to the existence of the folding plate assembly, the end plate 400 and the bed body do not necessarily need to form a connecting structure. In the embodiment, considering the folding plate assembly in the table plate function, the end plate 400 is inconvenient to separate and place, and the end plate 400 is permanently connected to the bed body (such as the horizontal rod vertical rod of the bed head), so that the end plate 400 does not need to be concerned in each use process. The end plate 400 and the bed structure connection mode can be a bandage or a clamp, and is not specially limited, and a common mode in the prior art is referred to.

[0063] In summary, the sleep-aiding table for bed provided by the utility model, when the side plate 200 is turned inwards, the volume occupied by the entire folding plate assembly is reduced, thereby facilitating storage, transportation and storage; when the side plate 200 is turned outwards, the folding plate assembly can be used as a table body on the bed; when the end plate 400 is combined with the folding plate assembly in the turned-out state, the end plate 400 encloses the folding plate assembly, thereby forming a sound-absorbing space, the outer periphery of the sound-absorbing space is wrapped by the sound-absorbing layer, at this time, the noise emitted from the head position is preferentially partially absorbed by the end plate sound-absorbing layer, the top plate sound-absorbing layer 110 and the side plate sound-insulating plate 210; the end plate sound-insulating plate, the top plate sound-insulating plate 120 and the side plate sound-insulating plate 220 generate a sound-insulating effect at the same time, and also reflect the noise that is not absorbed back to the sound-absorbing space direction, and the noise is absorbed again.

[0064] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation according to the content of the utility model specification and the drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
