[0045] In order to more clearly understand the above purpose, features and advantages of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0046] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0047] The following description will be made with reference to the drawingsFigure 1 to the attached Figure 7 The utility model discloses some embodiments described in the floor mat assembly 10.

[0048] As Figure 1 , Figure 2 and Figure 3 As shown in the utility model embodiment, a floor mat assembly 10 is provided, which comprises a floor mat body 100 and a suction cup assembly 200. The floor mat body 100 is provided with a mounting hole 110, and the suction cup assembly 200 comprises a suction cup body 210 and a cover connecting piece 220. The suction cup body 210 is located below the floor mat body 100, and the cover connecting piece 220 is located above the floor mat body 100. At least one of the suction cup body 210 and the cover connecting piece 220 extends into the mounting hole 110 and is connected.

[0049] Among them, the connection mode of the suction cup body 210 and the cover connecting piece 220 includes that a part of the cover connecting piece 220 passes through the mounting hole 110 downward and is connected with the suction cup body 210, a part of the suction cup body 210 passes through the mounting hole 110 upward and downward and is connected with the cover connecting piece 220, and a part of the suction cup body 210 and a part of the cover connecting piece 220 respectively extend into the mounting hole 110 and are connected.

[0050] It is worth mentioning that the embodiment does not limit the specific number of the suction cup assembly 200, and does not limit the arrangement mode of the plurality of suction cup assemblies 200. It can be designed according to the actual demand, for example, the floor mat body 100 can be designed as a rectangle, and the suction cup assembly 200 is arranged at the four corners of the floor mat body respectively. A plurality of suction cup assemblies 200 can also be designed to be scattered and installed on the floor mat body 100.

[0051] In the embodiment, the suction cup assembly 200 comprises the suction cup body 210 and the cover connecting piece 220 located on the upper and lower sides of the floor mat body 100. The suction cup body 210 and the cover connecting piece 220 are connected through the mounting hole 110 of the floor mat body 100. On the one hand, it can be understood that the suction cup body 210 and the cover connecting piece 220 are installed and fixed on the floor in the form of up and down limiting, the connection is more firm and not easy to loosen. On the other hand, the floor mat body 100 only needs to be provided with the mounting hole 110, and does not need to be provided with other structures for installing the suction cup assembly 200. That is, the suction cup assembly 200 can be fixed on the floor mat body 100. The processing technology of the floor mat body 100 is simpler, and the suction cup assembly 200 can be fixed on the floor mat body 100 of any material.

[0052] In one embodiment, the floor mat body 100 is an EVA piece. EVA material is widely used in floor mat products due to its softness, high elasticity, pressure resistance, wear resistance, water resistance, and moisture resistance. However, it is difficult to directly fix and install the suction cup on the EVA floor mat. By designing the suction cup as two parts, the suction cup body 210 and the cover connecting piece 220, the suction cup is fixed on the floor mat in the form of upper and lower limiting, and the connection is more firm and less likely to loosen.

[0053] It should be noted that the floor mat body 100 being an EVA piece is only one optional embodiment, and the material of the floor mat body 100 and the suction cup assembly 200 is not limited in the utility model. For example, the floor mat body 100 can be a PVC piece, a TPE piece, an EVA piece, etc., and the suction cup assembly 200 can be a metal piece, an injection molding piece, a silicone piece, etc.

[0054] In some embodiments, a part of the suction cup body 210 and a part of the cover connecting piece 220 respectively extend into the installation hole 110 and are connected, wherein the parts of the suction cup body 210 and the cover connecting piece 220 extending into the installation hole 110 are respectively matched with the installation hole 110, and the installation hole 110 can limit the suction cup assembly 200 in the radial direction, further avoiding the shaking and loosening of the suction cup assembly 200, and improving the connection reliability.

[0055] In some embodiments, the suction cup body 210 and the cover connecting piece 220 are integrally connected. Alternatively, the suction cup body 210 and the cover connecting piece 220 are integrally connected by welding, such as being integrally connected by fusion welding, pressure welding, thermoplastic welding, ultrasonic welding, etc. The integrally connected structure is more firm and less likely to loosen, and in the process of production and processing, the suction cup body 210 and the cover connecting piece 220 are independent parts, which can be conveniently placed on the upper and lower sides of the floor mat body 100, and then integrally connected by welding or other methods, which is more convenient for processing and production.

[0056] It should be noted that the suction cup body 210 and the cover connecting piece 220 are not limited to integrally connected, for example, the suction cup body 210 and the cover connecting piece 220 can also be connected by clamping, threaded connection, etc.

[0057] In some embodiments, as shown in Figs. 1 and 2, the cover connecting piece 220 is integrally connected with the floor mat body 100. Figure 4 Figure 5 As shown in Figs. 1 and 2, the cover connecting piece 220 includes a first plug-in part 221, and the suction cup body 210 includes a second plug-in part 2112, and the first plug-in part 221 and the second plug-in part 2112 are plug-in matched. In detail, the cover connecting piece 220 includes an integrally formed cover body 222 and the first plug-in part 221, the first plug-in part 221 extends downwardly from the lower surface of the cover body 222, the suction cup body 210 includes a disc body 212 for being adsorbed to the ground by negative pressure, and the second plug-in part 2112 is arranged at one end of the disc body 212. ​

[0058] The cover connector 220 and the suction cup body 210 are connected by a plug-in method, which makes the connection simpler. Especially in embodiments where the cover connector 220 and the suction cup body 210 need to be further welded into an integral structure, the cover connector 220 and the suction cup body 210 are pre-positioned by plugging in, which helps to ensure the reliability of the welding between the cover connector 220 and the suction cup body 210 during the welding process.

[0059] In some embodiments, the suction cup body 210 and the cover connector 220 are fixed by ultrasonic welding, resulting in short welding time, high welding quality, and reliable connection between the suction cup body 210 and the cover connector 220.

[0060] Among them, such as Figure 3 and Figure 4 As shown, one of the first insertion part 221 and the second insertion part 2112 has a guiding rib 2211, and the other has a groove 21121 adapted to the guiding rib 2211. The guiding rib 2211 is inserted into the groove 21121. The suction cup body 210 and the cover connector 220 are fixedly connected by ultrasonic welding at least at the guiding rib 2211 and the groove 21121.

[0061] In one possible embodiment, the lower wall of the first insertion portion 221 is designed to protrude downwards to form a power-conducting rib 2211, and the second insertion portion 2112 is designed to form a corresponding groove 21121. In another possible embodiment, the upper wall of the second insertion portion 2112 is designed to protrude upwards to form a power-conducting rib 2211, and the first insertion portion 221 is designed to form a corresponding groove 21121. Further, the power-conducting rib 2211 is designed to be annular, and the groove 21121 is a corresponding annular groove. The first insertion portion 221 and the second insertion portion 2112 form a reliable welded joint in the circumferential direction, resulting in a more robust connection.

[0062] During ultrasonic welding, ultrasonic vibration causes the energy-conducting rib 2211 and the groove 21121 to come into contact and rub against each other, rapidly generating local high temperatures. The energy-conducting rib 2211 melts preferentially, and then the molten material diffuses to both sides to form a weld, shortening the welding time and improving the welding quality. Furthermore, the energy-conducting rib 2211 and the groove 21121 are designed on the first insertion part 221 and the second insertion part 2112, respectively. While the first insertion part 221 and the second insertion part 2112 are inserted, the energy-conducting rib 2211 and the groove 21121 are also aligned, further improving the positional accuracy of the energy-conducting rib 2211 and the groove 21121, thereby improving the welding accuracy. The axial pressure of the first insertion part 221 and the second insertion part 2112 can act synchronously on the energy-conducting rib 2211, ensuring that the vibration energy is transmitted vertically and improving the uniformity of the weld thickness.

[0063] Optionally, the first plug-in part 221 comprises a first convex ring 2212 and a convex part 2213, the first convex ring 2212 is matched with the mounting hole 110, the convex part 2213 is arranged in the first convex ring 2212 and spaced from the first convex ring 2212, and the bottom wall of the first convex ring 2212 is outwardly convex to form an energy guide rib 2211, so that the structure of the cover connecting piece 220 is simpler and the processing is more convenient.

[0064] As shown in Figure 6 and Figure 7 The second plug-in part 2112 is configured with a first ring wall 21122 and a second ring wall 21123 protruding from the first ring wall 21122, the first ring wall 21122 and the second ring wall 21123 are transitionally connected, the first ring wall 21122 and the second ring wall 21123 define a groove 21121 corresponding to the part opposite to the first ring wall 21122, the second ring wall 21123 is plugged between the first convex ring 2212 and the convex part 2213, and the convex part 2213 is plugged in the second ring wall 21123.

[0065] Optionally, one or more of the outer wall surface of the convex part 2213, the outer wall surface of the second ring wall 21123, the inner wall surface of the second ring wall 21123, and the top surface of the second ring wall 21123 are formed as a bonding surface for ultrasonic welding. According to actual use requirements, more bonding surfaces are formed between the first plug-in part 221 and the second plug-in part 2112 to improve the connection reliability between the chuck body 210 and the cover connecting piece 220 and prevent breakage.

[0066] Optionally, the convex part 2213 is a hollow structure, and the hollow design is conducive to weight reduction of the cover connecting piece 220, thereby achieving overall weight reduction of the product.

[0067] Of course, in other embodiments, the convex part 2213 can also be designed as a solid structure.

[0068] Optionally, the part of the outer wall surface of the second ring wall 21123 protruding from the first ring wall 21122 and the part corresponding to the first ring wall 21122 are stepped.

[0070] In some embodiments, the suction cup body 210 comprises a connecting structure 211 and a disc body 212, the connecting structure 211 has a transitionally connected embedded part 2111 and a second plug-in part 2112, the embedded part 2111 is integrally connected with the disc body 212 as an injection molded insert. Generally, the suction cup fixes the floor mat by forming a negative pressure environment between itself and the ground, the embedded part 2111 of the connecting structure 211 can be integrally formed with the disc body 212 by the injection molding process, and the connecting structure 211 can use a material different from the disc body 212, such as a material with higher hardness and strength, to improve the connection reliability between the suction cup body 210 and the cover body connector 220.
