Technical Field
[0001] The utility model belongs to the technical field of XR sensors, and in particular relates to an XR sensor floor mat. Background Art
[0002] In the current era of rapid development of virtual reality (VR) and augmented reality (AR) technologies, XR sensors, as key components for precise interaction and positioning, play a vital role in many fields such as medical care, education, and entertainment. However, existing XR sensor mats have some problems in practical applications. For example, dust accumulation on the surface due to long-term use may affect the accuracy and stability of the sensor. At the same time, the traditional mat has a fixed structure and is difficult to adapt to the changes in size requirements for different application scenarios, which limits the flexibility and scope of application of XR devices to a certain extent.
[0003] Traditional floor mats often neglect cleaning and maintenance. Users need to clean them manually or replace them regularly, which is time-consuming and inconvenient. In addition, XR sensor floor mats on the market generally lack modular design. Once local damage occurs or the layout needs to be adjusted, the entire floor mat may need to be replaced as a whole, increasing the user's usage cost and maintenance difficulty. Utility Model Content
[0004] In view of this, the utility model provides an XR sensor floor mat, which improves the cleaning efficiency of the XR sensor floor mat by utilizing the principle of electrostatic adsorption.
[0005] The utility model is achieved in this way:
[0006] The utility model provides an XR sensor floor mat, wherein a main body comprises a sensing mechanism, a self-cleaning mechanism and a disassembly and assembly mechanism, a pressure sensing layer is provided at the bottom of the main body, the pressure sensing layer is used to detect the footsteps and force changes of the user on the floor mat, the sensing mechanism is embedded in the main body, the self-cleaning mechanism is integrated in the main body, comprises an electrostatic adsorption component and a cleaning brush component, and the disassembly and assembly mechanism is detachably located at the edge of the main body, and is used to seamlessly splice or separate the main body.
[0007] The control circuit board is also included, and the control circuit board is electrically connected to the pressure sensing layer, the infrared sensing module and the self-cleaning mechanism to control the working status of each component. The working linkage between the self-cleaning mechanism and the floor mat body is realized through the control circuit board, and the control circuit board will instruct the self-cleaning system to perform the corresponding cleaning task according to the preset program or the real-time monitored floor mat cleaning status information.
[0008] On the basis of the above technical solution, the XR sensor floor mat of the utility model can also be improved as follows:
[0009] The electrostatic adsorption component is specifically an electrostatic generator, which is embedded in the main body and is used to adsorb dust particles on the surface of the main body by generating a magnetic field.
[0010] Furthermore, the cleaning brush assembly includes a brush head made of a flexible bristle material and an electric motor drive mechanism. When the electrostatic adsorption is completed, the electric motor drives the brush head to clean the surface of the main body.
[0011] Flexible bristle materials generally include but are not limited to the following:
[0012] Nylon: Nylon is a common bristle material with good wear resistance, chemical corrosion resistance and elasticity. It is suitable for a variety of cleaning scenarios and has a relatively low cost.
[0013] Polyurethane (PU): Polyurethane bristles have extremely high resilience, softness and durability, and cause less scratch damage to the surface, making them suitable for cleaning sensitive or precision parts.
[0014] Silicone: Silicone bristles have good flexibility and anti-static properties. They can effectively absorb tiny particles without scratching the surface of the device. They are particularly suitable for cleaning electronic devices or high-precision devices such as XR sensor mats.
[0015] Artificial fibers: Bristles made of synthetic fibers such as PBT (polybutylene terephthalate) and PET (polyethylene terephthalate) are also often used. While ensuring the cleaning effect, they also have certain high temperature resistance and wear resistance.
[0016] Plant fiber: Some environmentally friendly products may use natural plant fibers such as palm fiber and coconut shell fiber to make bristles. These materials are skin-friendly and environmentally friendly, but may be slightly inferior to synthetic materials in terms of durability and elasticity. However, in some specific applications, their biodegradability and safety are more popular.
[0017] Furthermore, the disassembly and assembly mechanism is composed of a slot structure and a snap-fit component, the slot structure is located at the edge of the main body, and the snap-fit component is arranged at the end of the main body and cooperates with the slot structure.
[0018] The slot structure is located at the edge portion or the preset connection area of the floor mat, and is designed to be U-shaped, T-shaped or mortise and tenon-shaped, etc., which can be connected to each other, so as to facilitate the insertion and fixation of adjacent floor mat modules.
[0019] Furthermore, the buckle component includes a spring-loaded button buckle, or a sliding lock tongue structure.
[0020] When multiple floor mat modules need to be spliced, the buckle component of one module will be embedded in the slot structure of another module and fixed through the mechanical structure self-locking or locking mechanism to form a stable connection effect. When separating, just release the buckle locking state to easily separate the modules.
[0021] Furthermore, the disassembly and assembly mechanism is also provided with electrical connectors, such as magnetic connection terminals or plug-in connectors, for the continuity of the signal transmission lines between adjacent floor mat modules.
[0022] Furthermore, the cleaning brush assembly is integrated inside the main body, close to the pressure sensing layer and the lower part of the sensing mechanism.
[0023] Furthermore, the drive motor is used to provide power, and includes a transmission mechanism, such as a gear set and a pulley, for transmitting the power of the drive motor to the cleaning brush assembly, so that the bristles can perform reciprocating or rotational motion to clean the surface of the main body.
[0024] Furthermore, the sensing mechanism is specifically an infrared sensing mechanism.
[0025] Furthermore, it also includes a non-slip and wear-resistant surface layer covering the pressure sensing layer, and the non-slip and wear-resistant surface layer includes a rubber material, a silicone material or a composite material.
[0026] Rubber material: Rubber has good elasticity and anti-slip properties, can provide stable friction, and prevent users from slipping during use. At the same time, it has high wear resistance and is suitable for long-term use.
[0027] Silicone material: Silicone is an environmentally friendly, non-toxic, highly elastic material with a large surface friction coefficient, excellent anti-slip effect, and is wear-resistant and durable. It is often used in floor mat products.
[0028] Ceramic particles or metal oxide reinforced composite materials: This material is usually used in industrial environments. By adding wear-resistant ceramic particles or metal oxides to the coating, the surface hardness and wear resistance are greatly improved, and it also has a certain anti-slip effect.
[0029] Compared with the prior art, the XR sensor floor mat provided by the utility model has the following beneficial effects:
[0030] 1. Self-cleaning system: The innovative self-cleaning system based on the principle of electrostatic adsorption is introduced.

[0039] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.
[0040] like Figure 1 , Figure 2 , Figure 3As shown, it is an example diagram of the first embodiment of an XR sensor floor mat provided by the utility model. In this embodiment, the main body 10 includes a sensing mechanism, a self-cleaning mechanism 30 and a disassembly and assembly mechanism 40. A pressure sensing layer 11 is provided at the bottom of the main body 10. The pressure sensing layer 11 is used to detect the user's footsteps and force changes on the floor mat. The sensing mechanism is embedded in the main body 10, and the self-cleaning mechanism 30 is integrated in the main body 10, including an electrostatic adsorption component and a cleaning brush component 32. The disassembly and assembly mechanism 40 is detachably located at the edge of the main body 10, and is used to seamlessly splice or separate the main body 10.
[0041] Among them, in the above technical solution, the electrostatic adsorption component is specifically an electrostatic generator, which is embedded in the main body 10 and is used to adsorb dust particles on the surface of the main body 10 by generating a magnetic field.
[0042] The principle of electrostatic adsorption is a technology that uses the interaction force between electric charges to achieve material adsorption. In the XR sensor mat of the present utility model, the principle of electrostatic adsorption specifically refers to:
[0043] When the electrostatic generator in the self-cleaning system is working, it will generate an electrostatic field, which will cause a certain amount of static charge on the surface of the floor mat. Since tiny substances such as dust particles generally have a certain conductivity or carry a certain charge, they will be attracted by the electrostatic field and stay on the surface of the floor mat. This is because the attraction between different charges (positive and negative attract, like charges repel) causes dust particles with opposite charges to be tightly adsorbed by the charged surface of the floor mat.
[0044] In practical applications, electrostatic adsorption technology is often used for dust removal, air purification, and keeping the surface of objects clean. In the floor mat design of the present invention, by periodically starting the electrostatic generator to generate an electrostatic field and cleaning with the subsequent cleaning brush assembly, dust and particles attached to the surface of the floor mat can be effectively removed, thereby ensuring that the XR sensor is not affected by dust and always maintains its accuracy and stability.
[0045] Furthermore, in the above technical solution, the cleaning brush assembly 32 includes a brush head made of a flexible bristle material and an electric motor drive mechanism. After the electrostatic adsorption is completed, the electric motor drives the brush head to clean the surface of the main body 10. After the electrostatic generator generates an electrostatic field to adsorb the dust on the surface of the floor mat, the cleaning brush assembly will start at a preset time or when it detects that cleaning is needed, and the surface of the floor mat will be cleaned along a predetermined path by the electric motor drive. At this time, the cleaning brush assembly will move closely to the surface of the floor mat to ensure that the adsorbed dust is removed, while avoiding direct contact with the sensitive pressure sensing layer to ensure that its function is not affected.
[0046] Furthermore, in the above technical solution, the disassembly and assembly mechanism 40 is composed of a slot structure 41 and a snap-fit component 42 . The slot structure 41 is located at the edge of the main body 10 , and the snap-fit component 42 is arranged at the end of the main body 10 and cooperates with the slot structure 41 .
[0047] When adjusting the size of the floor mat, you only need to release the buckle and combine or disassemble the modules as needed without any complicated tool operation or rewiring, which greatly improves the flexibility and maintainability of the equipment. At the same time, the design of the quick disassembly interface also fully considers durability and dust and water resistance, ensuring good mechanical and electrical performance during long-term and frequent disassembly and assembly.
[0048] Furthermore, in the above technical solution, the buckle component 42 includes a spring-loaded button buckle, or a sliding lock tongue structure.
[0049] Furthermore, in the above technical solution, an electrical connector, such as a magnetic connection terminal or a plug-in connector, is also provided inside the disassembly and assembly mechanism 40 to ensure the continuity of the signal transmission line between adjacent floor mat modules.
[0050] Furthermore, in the above technical solution, the cleaning brush assembly 32 is integrated inside the main body 10, close to the pressure sensing layer 11 and the lower part of the sensing mechanism.
[0051] Furthermore, in the above technical solution, the drive motor is used to provide power, including a transmission mechanism, such as a gear set and a pulley, for transmitting the power of the drive motor to the cleaning brush assembly 32, so that the bristles can reciprocate or rotate to clean the surface of the main body 10.
[0052] Furthermore, in the above technical solution, the sensing mechanism is specifically an infrared sensing mechanism.
[0053] Furthermore, in the above technical solution, it also includes a non-slip and wear-resistant surface layer, which covers the pressure sensing layer 11, and the non-slip and wear-resistant surface layer includes a rubber material, a silicone material or a composite material.
[0054] It should be noted that the control circuit of the present invention can be controlled by simple programming. At the same time, the device component models used in the present invention are specifically as follows:
[0055] Cleaning brush assembly: You can choose bristles made of materials that are wear-resistant, moderately soft, and have good adsorption properties, such as the product series produced by companies such as Nidec or Maxon Motor that have precision motors with flexible nylon or silicone bristles. However, the specific models will change with market supply and technological updates, and need to be selected based on actual conditions.
[0056] Electric motor and drive motor: You can choose a micro DC motor or a stepper motor, such as a small, low-noise motor from Japanese Nidec or Maxon Motor. It should have enough torque to drive the cleaning brush for effective cleaning.
[0057] Electrostatic generator: The electrostatic generating module widely used in the electrostatic precipitator industry can be used, such as the industrial-grade electrostatic generator components provided by brands such as IONIX of the United States and Simco-Ion of Germany, which are used to generate an electrostatic field suitable for adsorbing dust particles. However, it is also necessary to select the most suitable model or customize the development based on the actual design requirements and the degree of equipment integration.
[0058] Infrared sensing mechanism: For the infrared sensing part, high-performance infrared sensor modules on the market can be selected, such as infrared proximity sensors or motion detection sensors provided by Sharp, Omron or other well-known manufacturers to capture the user's movement trajectory and motion posture on the XR sensor mat.
[0059] Specifically, the principle of the utility model is:
[0060] 1. The self-cleaning system works based on the principle of electrostatic adsorption. The electrostatic generator will generate an electrostatic field at a preset time or when dust accumulation is detected on the surface of the mat, adsorbing tiny particles on the surface of the mat. Subsequently, the cleaning brush assembly driven by the electric motor cleans the mat along a predetermined path to remove the adsorbed dust;
[0061] 2. The quick disassembly interface is composed of slot structure and buckle parts. The connection between modules is simple and easy. You only need to insert and lock it to complete the assembly. When disassembling, you can easily separate it by releasing the buckle. Each module is equipped with electrical connectors to ensure the continuity of the signal transmission line between adjacent modules without affecting the data transmission of the XR sensor;
[0062] 3. The non-slip and wear-resistant surface is made of specially treated rubber, silicone or other composite materials. These materials have a good friction coefficient, effectively preventing users from slipping, and have high wear resistance, ensuring that the floor mat can still maintain good performance under high-intensity use environments;
[0063] To sum up, the XR sensor floor mat of the utility model not only solves the problems existing in traditional floor mats, but also realizes automatic cleaning, modular installation and efficient anti-slip and wear-resistant functions, which significantly improves the user experience and practicality of XR equipment, and provides strong support for the widespread application of XR technology in more fields.
