Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

The array elastic support pad shown in Figures 1 to 41 includes a base plate 1 and an array unit 2, and a plurality of array units 2 are sequentially arranged and fixed on the base plate 1 to form a supporting whole, and the array unit 2 includes a base module 21 and an elastic support pad. The top cover 24 arranged on the base module 21, the base module 21 includes a support plate and a column 216 vertically arranged on the support plate, the column 216 is provided with an elastic support, and the top of the column 216 is provided with an upper limit Position structure, the top cover 24 is sleeved on the column 216, and is offset against the upper limit structure under the action of the elastic support.

The array units 2 are arranged in a honeycomb hexagonal arrangement or in a matrix, and parameters such as arrangement shape, pattern, and spacing can be adjusted during design according to specific use environments and use scenarios (as shown in FIG. 41 ).

A plurality of base modules 21 are integrally formed to form a "one"-shaped base row 20 . Forming a plurality of base modules 21 at one time not only improves production efficiency, but also helps to reduce costs, and in this way the entire cushion can be conveniently spliced by multiple array rows and fixed on the bottom plate. The base row 20 and the bottom plate 1 can be fixed by screws, riveting or glue. In addition, for the convenience of installation, multiple T-shaped or 7-shaped clips 101 can be arranged at intervals on the bottom plate. The basic installation of the whole cushion (as shown in Figures 39 and 40) can be completed within a short time.

For the convenience of production and installation, the top cover and the base module are connected by an upper cap, the inside of the top cover 24 is hollow, and the inner wall of the top cover 24 is provided with an upper limit protrusion 241 and a lower limit protrusion 242 at intervals. The upper cap 23 is clamped between the upper limit protrusion 241 and the lower limit protrusion 242 . The upper limit protrusion 241 and the lower limit protrusion 242 can be ribs along the inner wall, or a single protrusion or multiple protrusions. In order to facilitate the snap-in of the upper cap, the lower limit protrusion 242 The inner wall is curved. In this embodiment, the upper limit protrusion 241 is a plurality of ribs extending longitudinally, and the ribs are close to the corners. The ribs can not only limit the upper cap, but also increase the strength of the entire top cover (as shown in Figure 7 , Figure 8 and Figure 29, Figure 30).

As shown in Figure 9 to Figure 15 in detail the connection relationship between the top cover, the upper cap and the base module, the upper cap 23 is clamped in the top cover 24, the upper cap 23 is provided with an inner hole 2301, the inner A limit block 232 is also provided in the hole 2301, and the column 216 is provided with a chute 214, and the upper cap 23 acts on the elastic support so that the limit block 232 is against the top of the chute 214; and because the chute and the limit The cooperation of the blocks makes the movement of the top cover up and down traceable, and the relative shaking range is relatively small.

The upper cap 23 includes two upper cap combination blocks 231 that are engaged with each other. There are gaps on the opposite sides of the two upper cap combination blocks 231. The upper cap combination block 231 is respectively provided with notches 233 on both sides of the gap. And the protrusion 234, the two upper cap combination blocks 231 are fixed through the clamping of the notch 233 and the protrusion 234, and when the two upper cap combination blocks 231 are clamped, the gap is combined into an inner hole.

In addition, the limit block can also be replaced by a limit claw 2302, and the upper part of the chute 214 can also be opened, and only the corresponding position on the upper part of the chute 214 is set to the baffle plate 2101 and the limit claw 2302 can also be realized. The upper limit when the cap slides on the column prevents the top cover connected with the upper cap from detaching from the base module, which affects the user experience (as shown in Figures 18 to 24).

Figure 31 to Figure 38 show the connection relationship between the top cover, the second upper cap structure and the third base module in detail, the upper cap 23 can also be a whole, and the upper cap 23 is also clamped on the top cover 24, the upper cap 23 is also provided with an inner hole 2301, the upper cap 23 is sleeved on the column 216, and the top of the column 216 is provided with a convex edge 2161, and the upper cap 23 is connected to the The convex edge 2161 offsets.

The lower limit structure can also be added on the support plates of the above two mechanisms, and the lower limit structure can be the lower limit column 215 arranged at even intervals around the column, or the flange 2102 is evenly spaced on the outer wall of the column 216 bottom, and the top cover 24 Or when the upper cap 23 falls to the bottom, it will abut against the lower limit post 215 or the flange 2102 . At the same time, in order to ensure the stability of the limit, the lower limit post 215 or the flange 2102 are symmetrically arranged. Such a structure can effectively prevent the elastic support from being over-extruded, thereby affecting the service life. The elastic support can be a spring, Structures such as air rods or support sleeves made of deformable materials with resilience.

In addition to using clips to fix the base module, when using glue or screws to fix the base module to the bottom plate, it is necessary to pre-position the base bar for easy installation. The positioning structures include but are not limited to the following:

1. The opposite sides of the base module 21 are provided with base row convex cards 211 and base row concave cards 212 respectively, and the base row convex cards 211 and base row concave cards 212 on the same side of the base row are arranged alternately, corresponding The base row convex cards 211 and the base row concave cards 212 on two adjacent rows of base rows 20 are also misplaced to ensure that they can be plugged into each other; in other embodiments, only the base row convex cards can be provided on the same side of the base row 211 or base row concave card 212. The base row convex card 211 is formed by a single outwardly extending convex bar, and the base row concave card 212 is formed by two spaced apart convex bars, and a single convex bar is inserted into the accommodation space formed by the two convex bars to complete Preliminary positioning, and the base module 21 is also provided with a semicircular gap. After the two base rows 20 are assembled, the two semicircular gaps will form a plurality of positioning holes 213, and then the base can be fixed by passing through the fixing holes with screws. The row is firmly fixed to the base plate. When glue is used for fixing, positioning holes may not be provided (as shown in Fig. 4 to Fig. 6).

2. Inserting pieces 217 and slots 218 are respectively provided on opposite sides of the base module 21, and the inserting pieces 217 and slots 218 on the same side of the base row are interlaced with each other. The insertion pieces 217 and the slots 218 are also misplaced to ensure that they can be inserted into each other; in other embodiments, only the insertion pieces 217 or the slots 218 may be provided on the same side of the base row. When the two rows of bases are spliced together, the inserts are inserted into the slots to complete the preliminary positioning of the two rows of bases. Similarly, if the screw fixing method is adopted, a semicircular gap needs to be set on the base module 21. After the two bases 20 are assembled , two semicircular gaps will form a plurality of positioning holes 213, and then the base row can be firmly fixed on the base plate (as shown in Figure 25 to Figure 28 ) by passing through the fixing holes with screws.
