Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor device based on piezoluminescent materials. Background Art

[0002] Piezoluminescent materials are a special class of luminescent materials that can emit visible light when subjected to mechanical pressure or external stimulation. This luminescence phenomenon is due to the change in the crystal structure or electronic state of the material when it is subjected to pressure, resulting in the release of energy in the form of light.

[0003] Under the existing technology, the luminescent material is pressed together with pressure to realize the visualization of pressure sensing electroluminescent device, which is mainly composed of a pressure sensor array with a certain 3D structure and an electroluminescent display screen. The user only needs to press the corresponding pressure sensor array to make the corresponding position of the electroluminescent display screen light up. Nowadays, this kind of sensor is widely used and can be applied to toys, etc.

[0004] However, in actual use, we found that we can only press one place at a time, and combined pressing cannot be achieved. In addition, there is a lack of protection for pressing, and the pressure sensor array is often damaged due to heavy pressure.

[0005] Therefore, we propose a sensing device based on piezoluminescent materials that can protect against pressing to avoid excessive damage from pressing and can also achieve combined pressing to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a sensing device based on a piezoluminescent material to solve the problems raised in the above background technology.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A sensing device based on piezoluminescent materials includes a protective box, one end of which is fixedly connected to an electroluminescent display screen, one end of which is fixedly connected to a wiring terminal, a pressure sensor array is fixedly connected to the middle position of the bottom end of the protective box, a buffer spring is evenly fixedly connected to the bottom end of the protective box, a pressure plate is fixedly connected to the top end of the buffer spring, a threaded rod is evenly threadedly connected to the top end of the pressure plate, a disc is fixedly connected to the top end of the threaded rod, an intermediate column is slidably connected to the inside of the disc, and a spring connected to the outer wall of the intermediate column is fixedly connected to the bottom end of the inside of the disc.

[0009] As a further solution of the utility model: both sides of the protection box are threadedly connected with fixing bolts, and one end of the fixing bolts is fixedly connected to a limiting plate.

[0010] As a further solution of the utility model: a limiting groove is correspondingly provided on the inner wall of the protection box on one side of the limiting disk, and the top end of the limiting disk limits the height of the pressure plate.

[0011] As a further solution of the utility model: the diameter of the limiting groove is equal to the diameter of the limiting disk, and the depth of the limiting groove is equal to the thickness of the limiting disk.

[0012] As a further solution of the utility model: a protective ring is fixedly connected to the top of the interior of the protective box, and the bottom end of the protective ring is flush with the top of the pressure plate at the highest position.

[0013] As a further solution of the utility model: the bottom end of the interior of the protection box is fixedly connected to a limiting frame, and the limiting frame limits the minimum height of the pressure plate.

[0014] As a further solution of the utility model: the bottom end of the threaded rod is fixedly connected with an anti-slip disk, and the diameter of the anti-slip disk is larger than the diameter of the threaded rod.

[0015] Beneficial effects of the utility model:

[0016] 1. The sensing device based on piezoluminescent material in the utility model adjusts the height of the anti-detachment disk by rotating the corresponding disc to make the threaded rod rotate downward. At this time, pressing the pressure plate downward can make the anti-detachment disk at a lower position press the pressure sensor array to achieve combined pressing. When combined pressing is not required, the fixing bolt can be rotated to limit the pressure plate. At this time, the middle column can be pressed alone to achieve the pressing and triggering of the pressure sensor array, which can achieve a single press, thereby meeting the use of various situations.

[0017] 2. The downward movement of the pressure plate of the sensor device based on piezoluminescent material in the utility model will preferentially overcome the elasticity of the buffer spring to provide buffering, and finally the descent of the pressure plate will be limited by the limit frame, thereby finally protecting the pressure sensor array and preventing the pressure sensor array from being damaged by gravity.

[0025] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. 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.

[0026] like Figure 1-Figure 5 In this embodiment, the sensing device based on piezoluminescent material includes a protective box 1, one end of the protective box 1 is fixedly connected to an electroluminescent display screen 7, one end of the protective box 1 is fixedly connected to a terminal 2, a pressure sensor array 9 is fixedly connected to the middle position of the bottom end of the protective box 1, a buffer spring 11 is evenly fixedly connected to the bottom end of the protective box 1, the top of the buffer spring 11 is fixedly connected to a pressure plate 8, the top of the pressure plate 8 is evenly threadedly connected to a threaded rod 14, the top of the threaded rod 14 is fixedly connected to a disk 3, the inside of the disk 3 is slidably connected to an intermediate column 4, and the bottom end of the inside of the disk 3 is fixedly connected to a spring connected to the outer wall of the intermediate column 4.

[0027] like Figure 1-Figure 4 In this embodiment, both sides of the protective box 1 are threadedly connected with fixing bolts 5, and one end of the fixing bolts 5 is fixedly connected to a limiting plate 13. By rotating the fixing bolts 5, the limiting plate 13 protrudes to limit the pressure plate 8, thereby achieving the limitation of the pressure plate 8.

[0028] like Figure 1-Figure 4 In this embodiment, a limiting groove 12 is correspondingly provided on the inner wall of the protection box 1 on one side of the limiting plate 13, and the top of the limiting plate 13 limits the height of the pressing plate 8 so that the height of the pressing plate 8 can be limited by the limiting plate 13.

[0029] like Figure 2-Figure 4In this embodiment, the diameter of the limiting groove 12 is equal to the diameter of the limiting plate 13, and the depth of the limiting groove 12 is equal to the thickness of the limiting plate 13, so that the fixing bolt 5 can be rotated to receive the limiting plate 13 into the limiting groove 12, thereby realizing the storage of the limiting plate 13.

[0030] like Figure 1 and Figure 2 In this embodiment, a protective ring 6 is fixedly connected to the top of the protective box 1, and the bottom end of the protective ring 6 is flush with the top of the highest pressure plate 8, so that a certain degree of sealing is performed through the protective ring 6 to prevent dust from entering through the gap.

[0031] like Figure 2 and Figure 3 In this embodiment, the bottom end of the protection box 1 is fixedly connected to a limit frame 10, and the limit frame 10 limits the minimum height of the pressure plate 8 to prevent the pressure plate 8 from being over-pressed and causing damage to the pressure sensor array 9.

[0032] like Figure 5 In this embodiment, the bottom end of the threaded rod 14 is fixedly connected with an anti-slip disk 15, and the diameter of the anti-slip disk 15 is larger than the diameter of the threaded rod 14, so that the anti-slip disk 15 prevents the threaded rod 14 from separating from the pressure plate 8.

[0033] It can be understood that the sensing device based on piezoluminescent material can rotate and adjust the corresponding disc 3 so that the anti-slip disc 15 is at a corresponding height, that is, when the pressure plate 8 is pressed down, the corresponding pressure sensor array 9 can be pressed to achieve a combined press, or the middle column 4 can be pressed alone to achieve a single press, which can meet the use in different situations. At the same time, buffering and limiting can be performed during the pressing process to avoid excessive damage due to pressing.

[0034] The complete usage steps and working principle of the utility model are as follows:

[0035] When combined pressing is required, the corresponding disc 3 can be rotated to make the threaded rod 14 rotate downward, so that the anti-slip disc 15 is at the corresponding height. When combined pressing is not required, it is only necessary to rotate the anti-slip disc 15 so that it is flush with the bottom end of the inner side of the pressure plate 8 and limit the position. At this time, it is only necessary to press the pressure plate 8 downward so that the anti-slip disc 15 presses the pressure sensor array 9, so that the electroluminescent display screen 7 in the corresponding area lights up. When combined pressing is not required, the fixing bolt 5 can be rotated so that the limiting disc 13 is under the pressure plate 8 to limit the pressure plate 8. At this time, the middle column 4 can be pressed alone to realize the pressing and triggering of the pressure sensor array 9, so as to realize a single press.

[0036] During the combined pressing process, the downward movement of the pressure plate 8 will first overcome the elasticity of the buffer spring 11 for buffering, and finally the descent of the pressure plate 8 will be limited by the limit frame 10, thereby finally protecting the pressure sensor array 9 and preventing the pressure sensor array 9 from being damaged by gravity.

[0037] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
