DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0040] In the prior art, bathroom mats use a solution of pressure sensors. When using the pressure sensor for detection, it is necessary to calculate and extract the pressure detection value, and also to filter the value, which requires complex hardware circuit design and software calculation, and the price of the pressure sensor is relatively high.

[0041] Based on this, an embodiment of the utility model discloses a low-cost anti-skid foot pad, which is mainly used in relatively slippery scenes such as bathrooms.

[0042] See also Figures 1 to 9 An anti-slip foot pad of an embodiment includes a foot pad body 100, a sensing device 200 and a control device 300. The foot pad body 100 is provided with an interlayer space 110. The sensing device 200 includes a plurality of trigger modules 210. Each trigger module 210 is spaced apart in the interlayer space 110. The trigger module 210 includes a conductive spring 211 and a trigger plate 212. The conductive spring 211 covers the conductive contact of the trigger plate 212. Pressing the foot pad body 100 can apply pressure to a part of each trigger module 210, thereby causing the conductive spring 211 of some of the trigger modules 210 in each trigger module 210 to elastically deform, and the conductive spring 211 contacts the conductive contact of the trigger plate 212 to conduct electricity. The control device 300 is electrically connected to each trigger module 210 and is used to sense the conductive state of each trigger module 210.

[0043] It is understandable that the control device 300 can determine whether a user has fallen according to the conductive state of each trigger module 210, and the trigger unit using the conductive spring 211 and the trigger plate 212 can timely determine the pressure state of each trigger module 210. Compared with the cost reduction of the existing pressure sensor application solution, the cost of the anti-slip foot pad is low, which is conducive to the market competitiveness of the anti-slip foot pad. In this embodiment, each trigger module 210 has only two pressure states, namely, pressure and no pressure, and each trigger module 210 cannot sense the pressure.

[0044] In one embodiment, the foot pad body 100 is a pad body made of a silicone material, which has good elastic deformation ability and provides a comfortable touch for users to step on.

[0045] In one embodiment, see Figure 3The sensing device 200 further includes a wire 220, and two adjacent trigger modules 210 are connected by the wire 220. The trigger modules 210 are arrayed in the interlayer space 110, so that the pressure of each part of the foot pad body 100 can be sensed to determine the pressure state of the foot pad body 100. Of course, in other embodiments, the sensing device 200 may also include a flexible circuit board, and the trigger modules 210 are distributed on the flexible circuit board, and the electrical connection between the trigger modules 210 is realized through the flexible circuit board.

[0046] In one embodiment, see Figure 3 The control device 300 is electrically connected to each trigger module 210 through a wire 220. The control device 300 is arranged outside the foot pad body 100 and extends to a preset placement position through the wire 220, so that the control device 300 can be easily stored in a preset safe environment, ensuring that the control device 300 will not be affected by environmental factors such as humidity, and ensuring that the control device 300 can work stably and reliably.

[0047] Further, in this embodiment, please refer to Fig.10 and Fig.11 The control device 300 includes a control body 310, and a wireless module, a warning light 320, a sound alarm, a battery 330, a control switch 340 and a control mainboard 350 arranged on the control body 310. The control mainboard 350 is electrically connected to the wireless module, the warning light 320, the sound alarm, the battery 330 and the control switch 340; the control mainboard 350 is electrically connected to each trigger module 210. The switch of the anti-skid foot pad can be controlled by the control switch 340, and the anti-skid foot pad can be powered by the battery 330.

[0048] It is understandable that the control mainboard 350 can sense the conductive state of each trigger module 210, so as to determine whether a user has fallen. After determining that a user has fallen, the control mainboard 350 can communicate with an external mobile phone or other terminal system through a wireless module, and send a warning message to the mobile phone or other terminal system. Of course, the triggering state of the anti-slip mat can also be monitored through the mobile phone or other terminal system. At the same time, the control mainboard 350 can also control the warning light 320 to emit a warning light, and control the sound alarm to emit a warning sound such as a buzzer, so as to attract the attention of other personnel, so that the user can be rescued in time.

[0049] Specifically, the control mainboard 350 is also provided with a charging interface, through which the anti-slip foot pad can be directly powered, or the battery 330 can be charged. The charging interface can be a Type-C interface. Further, the wireless module can be a Bluetooth module and / or a WiFi module.

[0050] In this embodiment, the control body 310 includes a first shell 311 and a second shell 312, the first shell 311 and the second shell 312 are surrounded to form a housing cavity for accommodating the battery 330 and the control main board 350, and the control body 310 is provided with a sound hole 313 corresponding to the sound alarm and a charging socket 314 corresponding to the charging interface. The warning light 320 and the control switch 340 are exposed on the outer wall of the control body 310.

[0051] In one embodiment, see Figure 3 and Fig. 9 The foot pad body 100 includes a bottom pad body 120 and an upper pad body 130. The upper pad body 130 is stacked on top of the bottom pad body 120 and is enclosed with the bottom pad body 120 to form a sandwich space 110. The separate arrangement of the bottom pad body 120 and the upper pad body 130 facilitates the arrangement of each trigger module 210 in the sandwich space 110.

[0052] It should be noted that, since the anti-slip foot pad of this embodiment can be used in relatively slippery scenes such as bathrooms, it is necessary to ensure the sealing of the interlayer space 110 to ensure the stability and reliability of the operation of each trigger module 210.

[0053] In one embodiment, see Figure 1 , Figure 2 and Fig. 9 The upper pad body 130 is provided with an anti-skid protrusion 131, and the upper pad body 130 includes a first side portion 132 and a second side portion 133 that are relatively arranged. The first side portion 132 is arranged toward the bottom pad body 120, and the anti-skid protrusion 131 is arranged to protrude from the surface of the second side portion 133, thereby facilitating the improvement of the anti-skid performance of the anti-skid foot pad.

[0054] In one embodiment, see Fig. 9 The anti-slip protrusion 131 is provided with a button protrusion 134 at the first side portion 132. There are multiple button protrusions 134, and they are arranged one by one corresponding to each trigger module 210. Pressing the anti-slip protrusion can cause the button protrusion 134 to move close to the conductive spring sheet 211 and abut against the conductive spring sheet 211 to deform. The conductive spring sheet 211 contacts and conducts electricity with the conductive contact of the trigger plate 212. The control device 300 senses the conductive state of the trigger module 210, thereby completing the pressure sensing of the anti-slip foot pad.

[0055] Furthermore, the anti-skid protrusion 131 is provided with a recessed portion 135 at the first side portion 132, and the button protrusion 134 is provided at the center of the recessed portion 135, which is conducive to the light and thin setting of the anti-skid foot pad. It can be understood that by installing the trigger module 210 at the anti-skid protrusion 131, not only can the foreign body feeling of the trigger module 210 be hidden, but also the pressure triggering of the trigger module 210 can be facilitated.

[0056] Preferably, the spacing between two adjacent anti-slip protrusions 131 is between 40mm and 60mm. Specifically, the spacing between two adjacent anti-slip protrusions 131 can be selected to be 40mm, 45mm, 50mm, 55mm or 60mm. By setting the above spacing size, the anti-slip effect of the anti-slip protrusions 131 can be improved, and the user can be prevented from slipping during bathing. At the same time, the anti-slip protrusions 131 can also have the effect of a massage plate, promote blood circulation in the human foot, and play a certain massage effect.

[0057] For details, please refer to Figures 6 to 9 The conductive spring 211 is a circular key spring, an elliptical key spring, a square key spring, a cross key spring or a triangular key spring made of metal material. The conductive spring 211 can be elastically deformed after being compressed, and the conductive spring 211 contacts the conductive contact of the trigger plate 212 to conduct electricity, completing the compression triggering of the trigger module 210. In the free state, the conductive spring 211 can be elastically reset to release the contact between the conductive spring 211 and the conductive contact on the trigger plate 212.

[0058] It can be understood that the conductive spring 211 is a key spring (also known as a metal dome, snapdome). The trigger module 210 of this embodiment can apply the membrane switch technology of the prior art. When the key spring is pressed, the center point of the key spring is concave and contacts the conductive contact on the trigger plate 212 to form a loop. At this time, the current passes and is sensed by the control motherboard 350. In the free state, the key spring is elastically reset, and there is a gap between the key spring and the conductive contact on the trigger plate 212, and no loop is formed. At this time, no current passes and is sensed by the control motherboard 350, so that the two states of being pressed and not being pressed can be provided by whether the trigger module 210 is pressed. The membrane switch technology is lower in cost than the pressure sensor.

[0059] In one embodiment, see Figure 3 , Figure 4 and Fig. 9 A mounting protrusion 121 is provided on the bottom pad body 120, a mounting groove 122 is opened in the mounting protrusion 121, and the trigger module 210 is arranged in the mounting groove 122; there are multiple mounting protrusions 121, and they are arranged one by one corresponding to each trigger module 210, so as to facilitate the stable arrangement of each trigger module 210 in the interlayer space 110.

[0060] Specifically, the trigger module 210 is completely accommodated in the mounting groove 122, and the button protrusion 134 is a silicone protrusion. By embedding the trigger module 210 in the mounting groove 122, it is beneficial to the lightweight setting of the anti-slip foot pad, and the foreign body sensation of setting the trigger module 210 in the foot pad body 100 can be further reduced. In addition, the setting of the mounting groove 122 can also protect the trigger module 210 to prevent damage to the trigger module 210 due to the user's stepping on it.

[0061] In one embodiment, see Figures 1 to 5 The foot pad body 100 is provided with a water leakage hole 140, which is set through the foot pad body 100. There are multiple water leakage holes 140, which are evenly distributed on the foot pad body 100. Through the setting of the water leakage holes 140, the water flow on the anti-slip foot pad is easily discharged and the water is quickly drained. Specifically, the foot pad body 100 can be selected to be square, round or oval.

[0062] In one embodiment, the distance between two adjacent anti-skid protrusions 131 is 50 mm, and the area of ​​the sole of an adult's foot is set at 110 mm×250 mm. When the user stands normally, the two soles of the feet can cover about 35-45 trigger modules 210, that is, 35-45 trigger modules 210 are under pressure. When the user falls, at least 50 or more trigger modules 210 are covered, that is, more than 50 trigger modules 210 are under pressure. Using the anti-skid foot pad of this embodiment, it is possible to simply count the number of trigger modules 210 under pressure to determine whether the user has fallen.

[0063] It is understandable that after the user falls, the contact area between the body part and the anti-slip foot pad will be larger than the contact area between the user's feet and the anti-slip foot pad. Therefore, it is possible to determine whether the user falls during the bathing process by determining the amount of pressure on the trigger module 210.

[0064] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
