DETAILED DESCRIPTION
[0028] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.
[0029] As a specific embodiment, the double mesh seat cushion assembly of the embodiment of the utility model includes a base 1, an inner mesh frame 2 and an outer mesh frame 3.
[0030] The base 1 is provided with an inner frame groove 12 and an outer mesh groove 13 located outside the inner frame groove 12 .
[0031] The inner mesh frame 2 is provided with an inner mesh cloth 29, and the outer mesh frame 3 is provided with an outer mesh cloth 39. It is easy to understand that the inner mesh cloth 29 and the outer mesh cloth 39 are both conventional fabrics with air permeability and elasticity.
[0032] The inner mesh frame 2 and the outer mesh frame 3 are respectively embedded in the inner frame groove 12 and the outer mesh groove 13, so that the outer mesh cloth 39 is located outside the inner mesh cloth 29 and is close to or close to the inner mesh cloth 29. In other words, the inner mesh frame 2 is embedded in the inner frame groove 12 and the outer mesh frame 3 is embedded in the outer mesh groove 13. It is easy to understand that the outer mesh frame 3 and the outer mesh cloth 39 thereon can be multiple arranged from the inside to the outside. Since the inner mesh frame 2 and the outer mesh cloth 39 jointly support the human body, under the premise of the same use time, the mesh cloth collapse can be alleviated and the use comfort can be improved.
[0033] As one of the specific implementations, the inner frame 2 and the outer frame 3 are both in the shape of a square frame as a whole; the inner frame 2 includes an inner frame side beam 21 and an inner frame cross beam 22, and the outer frame 3 includes an outer frame side beam 31 and an outer frame cross beam 32, and the inner frame cross beam 22 and the outer frame cross beam 32 are both concave. Figure 4 As shown, a recess height 4 is provided between the outer mesh frame side beam 31 and the outer mesh frame cross beam 32, so that the outer mesh frame cross beam 32 is recessed, and the same is true for the inner mesh frame cross beam 22. The recess height 4 makes the inner mesh 29 and the outer mesh 39 in a recessed state in a natural state, thereby alleviating the collapse of the mesh and improving the comfort of use.
[0034] As one of the specific implementations, the outer mesh 39 extends from the front end face of the outer mesh frame 3 to beyond the outer mesh frame 3 and then bends and surrounds the outer edge of the outer mesh frame 3; the inner mesh 29 extends from the front end face of the inner mesh frame 2 to beyond the inner mesh frame 2 and then bends and surrounds the outer edge of the inner mesh frame 2. During assembly, the inner mesh frame 2 is first inserted into the inner frame groove 12, and then the outer mesh frame 3 is inserted into the outer mesh groove 13 and then fastened. The inner mesh frame 2 and the inner mesh 29, and the outer mesh frame 3 and the outer mesh 39 can be pre-assembled without being assembled on the base 1, which is convenient for assembling the double mesh seat cushion assembly.
[0035] As one of the specific implementations, Figure 4 , 5 As shown, the front end surface of the inner mesh frame 2 and the front end of the outer mesh frame 3 are both inclined inward and are located on the same curved surface, which can ensure that the inner mesh cloth 29 and the outer mesh cloth 39 fit closely on the front end surface of the inner mesh frame 2, thereby improving comfort.
[0036] As one of the specific implementations, the base 1 is provided with a connection hole 19, and a screw (not shown in the drawings) passes through the connection hole 19 and is screwed into the rear end face of the inner mesh frame 2 and the rear end face of the outer mesh frame 3. The front end face of the inner mesh frame 2 and the front end face of the outer mesh frame 3 are both curved surfaces without protrusions, which can ensure that the inner mesh 29 and the outer mesh 39 fit the front end face of the inner mesh frame 2 while ensuring comfort in use.
[0037] As one of the specific implementations, the outer edge of the outer mesh frame 3 is provided with an outer edge protrusion 33, which abuts against the base 1 and clamps the outer mesh 39 with the base 1. The fixing area of the outer mesh 39 and the fixing strength of the outer mesh 39 can be increased.
[0038] As one of the specific implementations, there is a difference between the elastic coefficient of the inner mesh 29 and the elastic coefficient of the outer mesh 39. For example, the inner mesh 29 contains a relatively thick rubber band with a larger elastic coefficient, and the outer mesh 39 contains a relatively thin rubber band with a smaller elastic coefficient, so that there is a difference in the elastic coefficients of the two. When the human body acts on the outer mesh 39 and the inner mesh 29, the outer mesh 39 is easier to deform and transmits the force of the human body to the inner mesh 29, which can ensure that the inner mesh 29 and the outer mesh 39 fit together and improve comfort.
[0039] As one of the specific implementations, a spacer 121 is provided at the corner of the inner frame groove 12, and the corner of the inner mesh frame 2 (i.e., the outer edge of the inner mesh frame 2, and the outer edge of the inner mesh frame 2 is surrounded by the inner mesh cloth 29) is against the spacer 121. The fixing strength of the inner mesh cloth 29 at the corner can be improved, and the mesh cloth collapse can be further alleviated.
[0040] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.
[0041] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.
[0042] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.
[0043] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the relevant standards of dimensional tolerance.
