DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1 A self-service terminal with OCR recognition function, such as Figure 1-7 As shown, it includes a terminal 1, a sliding plate 2, a support rod 3 and an electric wheel 4; a power supply is provided in the terminal 1; the sliding plate 2 is slidably connected to the lower part of the terminal 1; the sliding plate 2 is fixedly connected to two support rods 3; each support rod 3 is respectively equipped with an electric wheel 4; and the electric wheel 4 is connected to the power supply; It also includes a support plate 5, an electric moving block 6 and an electric push rod 7; each support rod 3 is fixedly connected to an electric push rod 7; the telescopic parts of all the electric push rods 7 are commonly fixedly connected to the support plate 5, and the support plate 5 is initially located in the sliding plate 2; the terminal 1 is slidably connected to two electric moving blocks 6; the electric moving blocks 6 and the electric push rods 7 are both connected to a power source.

[0022] It also includes absorbent cloth 101 and tension springs 102; six tension springs 102 are connected to the left and right sides of the sliding plate 2; all tension springs 102 are fixedly connected to the absorbent cloth 101; the lower part of the absorbent cloth 101 is located in the sliding plate 2, and the upper part of the absorbent cloth 101 wraps the support plate 5.

[0023] It also includes an airbag 111, an air intake pipe 112, an air pump 113 and a connecting pipe 114; the airbag 111 is fixedly connected between the sliding plate 2 and the support plate 5; the air intake pipe 112 is fixedly connected to the rear of the sliding plate 2; the air intake pipe 112 is connected to the airbag 111; the air intake pipe 112 is connected to the air pump 113; the sliding plate 2 is fixedly connected to a connecting pipe 114, and the connecting pipe 114 is used for exhaust; an electrically controlled valve is fixedly connected to the inside of the connecting pipe 114.

[0024] The support plate 5 is provided with a communication cavity 5a; the support plate 5 is provided with a plurality of air injection holes 5b; all the air injection holes 5b are commonly communicated with the communication cavity 5a; and the communication pipe 114 is communicated with the communication cavity 5a.

[0025] The specific working steps are: When the user needs to take a photo but is not tall enough during the process of using the terminal 1 to perform identity collection and other operations, the user controls the electric wheel 4 to rotate through the terminal 1 operation panel, so that the electric wheel 4 drives the support rod 3 and the sliding plate 2 to move forward, and most of the sliding plate 2 is moved out. Then the user can step on the sliding plate 2 to perform identity collection and other operations. When the user finds that the height increased by stepping on the sliding plate 2 is not enough, the user controls the electric push rod 7 through the terminal 1 operation panel to push the support plate 5 up. When the support plate 5 rises to the highest height, the electric moving block 6 extends out and fits the lower surface of the support plate 5. At this time, the electric moving block 6 will play a supporting role, and then the user steps on the sliding plate 2 to perform identity collection and other operations. After the identity is collected, the electric moving block 6 is first controlled to move back to its original position, and then the electric push rod 7 is controlled to drive the support plate 5 to descend and return to its original position. Finally, the electric turntable 4 is controlled to rotate to drive the support rod 3 and the sliding plate 2 to return to their original positions. Through the cooperation of the sliding plate 2 and the support plate 5, the user can choose the stepping height according to his or her own height, so that the pedal cannot be set higher, thereby avoiding the problem that users who only need a small increase in height have difficulty maintaining balance when using a pedal with a higher height. The invention also intelligently controls the extension and retraction of the pedal, thereby avoiding the problem that the user directly contacts the pedal and causes virus infection, and the intelligence can facilitate the user to operate, thereby avoiding increasing the burden on the user to handle business.

[0026] When the sliding plate 2 and the support plate 5 are in use, the soles of the user's shoes will inevitably be attached to foreign debris such as mud, leaves or rainwater, especially mud, which is easy to enter the gap between the sliding plate 2 and the support plate 5, thereby affecting the expansion and contraction of the support plate 5, causing potential mechanical interference and wear problems, and the fallen mud is not easy to clean. When the support plate 5 is raised, the mud will fall into the middle of the sliding plate 2, thereby causing the support plate 5 to be blocked when it is contracted, and thus cannot be completely contracted. The attached rainwater is easy to slip, thereby causing the user to slip and fall. Therefore, when in use, the absorbent cloth 101 will play a role of shielding and absorbing water, preventing mud and sand from entering the gap between the sliding plate 2 and the supporting plate 5, and the rainwater on the soles of the users' shoes will be absorbed by the absorbent cloth 101, thereby avoiding slipping. When the supporting plate 5 rises, the supporting plate 5 will drive the absorbent cloth 101 to rise. At this time, the absorbent cloth 101 will pull the tension spring 102 to stretch it. Since the area of ​​the absorbent cloth 101 is larger than that of the supporting plate 5, the fallen sand and stones will fall out of the range of the sliding plate 2 and avoid falling into the middle of the sliding plate 2.

[0027] After long-term use, parts will have problems of wear and aging. Since the support plate 5 and the electric moving block 6 play a key supporting role, most of the pressure is applied to the support plate 5 and the electric moving block 6 during use, making it easier for the support plate 5 or the electric moving block 6 to break during use. When the support plate 5 or the electric moving block 6 breaks, it causes unbalanced support for the user, which in turn causes the user to fall. Therefore, when the support plate 5 is rising, the air pump 113 will input gas into the airbag 111, so that the airbag 111 expands synchronously. At this time, the airbag 111 will play an emergency supporting role to avoid the situation where there is no support when the support plate 5 or the electric moving block 6 breaks, resulting in unbalanced support for the user, which in turn causes the user to fall. When the support plate 5 descends, the electric control valve is controlled to open, so that the gas is discharged from the connecting pipe 114.

[0028] When the gas is discharged from the connecting pipe 114, the gas will enter the connecting cavity 5a, and then be sprayed out from the jet hole 5b onto the absorbent cloth 101. Therefore, when a large amount of rainwater is attached to the absorbent cloth 101, the air pump 113 is controlled to continuously supply gas to the airbag 111, and the electronically controlled valve will also be in an open state. At this time, the airbag 111 will become a conveying channel, so that the gas is continuously sent to the connecting pipe 114, and then sprayed out from the jet hole 5b, thereby drying the absorbent cloth 101.

[0029] Example 2 On the basis of Example 1, Figure 3-5As shown, it also includes a water inlet pipe 1 201, a water pump 202, a water inlet pipe 203, bristles 205 and an electric movable plate 206; the terminal 1 is provided with a collection space 1a, and the terminal 1 is also provided with a water storage space 1b, the terminal 1 is provided with a water inlet tank 1c, the water inlet tank 1c is connected with the collection space 1a, the collection space 1a and the water storage space 1b are respectively provided with a connecting port, the terminal 1 is fixedly connected with a water inlet pipe 1 201, the water inlet of the water inlet pipe 1 201 is connected with a water pump 202, and the water pump 202 is located in the water storage space 1b; the sliding plate 2 is fixedly connected with the water inlet pipe 1 It is connected to water inlet pipe 203; water inlet pipe 203 is directly opposite to the water outlet of water inlet pipe 1 201, and water inlet pipe 203 is snap-fitted with the water outlet of water inlet pipe 1 201; water inlet pipe 203 is connected to the air bag 111, and a one-way valve is provided in water inlet pipe 203 to prevent gas from flowing out of water inlet pipe 203; a plurality of bristles 205 are connected to the sliding plate 2; the sliding plate 2 is installed with an electric movable plate 206; all the tension springs 102 on the right are fixedly connected to the electric movable plate 206; all the tension springs 102 on the left are fixedly connected to the sliding plate 2.

[0030] It also includes an electric lifting plate 204 ; the terminal 1 is installed with the electric lifting plate 204 , and the electric lifting plate 204 is located above the sliding plate 2 ; all the bristles 205 are fixedly connected to the electric lifting plate 204 .

[0031] It also includes a silicone scraper 211 ; the front of the electric lifting plate 204 is fixedly connected to the silicone scraper 211 ; a groove 2a is provided on the front of the upper side of the sliding plate 2 , and the groove 2a is located directly below the silicone scraper 211 .

[0032] The rear portion of the sliding plate 2 is fixedly connected with a water retaining block 212 , which blocks the water flowing down during cleaning to prevent the water from flowing directly to the air pump 113 , thereby affecting the air pump 113 .

[0033] The specific working steps are: The communication port provided in the collecting space 1a is connected to a drainage pipe, and the other end of the drainage pipe is connected to a sewer; the communication port provided in the water storage space 1b is connected to an external water supply device.

[0034] When the business of the day is over, the sliding plate 2 is located in the terminal 1, and the water outlet of the water inlet pipe 1 201 is in a clamping state with the water inlet of the water inlet pipe 2 203. The water pump 202 is turned on to deliver water to the electric movable plate 206, so that the water enters the water inlet pipe 203 from the electric movable plate 206, and then enters the air bag 111. Then, the electric control valve is opened to discharge the water from the connecting pipe 114 into the connecting cavity 5a, and finally sprayed from the jet hole 5b to the absorbent cloth 101. At the same time, the electric movable plate 206 will drive the puller connected to it. The tension spring 102 moves left and right, and the tension spring 102 will pull the absorbent cloth 101 to move left and right when it moves, so that the bristles 205 brush the absorbent cloth 101 left and right, and then clean the mud and sand attached to the absorbent cloth 101, avoiding time-consuming and labor-intensive manual cleaning. The absorbent cloth 101 can then be used again after air drying, and the cleaned mud and sand will be discharged into the collection space 1a from the water inlet trough 1c with water, and then discharged into the sewer. When the water in the water storage space 1b is not enough for cleaning, clean water is delivered by an external water delivery device.

[0035] It should be noted that if the bristles 205 are in contact with the absorbent cloth 101 at the beginning, when the sliding plate 2 moves, the bristles 205 will play a friction deceleration role, and the bristles 205 will be worn when not in use, resulting in poor cleaning effect and the need for frequent replacement. Therefore, when cleaning work is needed, the electric lifting plate 204 drives the bristles 205 to descend and contact the absorbent cloth 101 for cleaning work, ensuring that the bristles 205 are in contact with the absorbent cloth 101 when cleaning work is needed, avoiding excessive wear of the bristles 205.

[0036] When the sliding plate 2 is moving, the silicone scraper 211 will scrape off the mud and sand attached to the surface of the absorbent cloth 101, thereby reducing the adhesion of mud and sand, extending the service life of the absorbent cloth 101, and reducing the number of cleaning times. When cleaning, the electric lifting plate 204 will drive the silicone scraper 211 to descend, so that the silicone scraper 211 is stuck in the groove 2a. At this time, the silicone scraper 211 will play a blocking role, preventing the water from being discharged from the front of the sliding plate 2 during cleaning, resulting in a large amount of dirty water accumulating on the ground and requiring manual cleaning.

[0037] Example 3 On the basis of Example 2, Figure 4-5 As shown, a silica gel block 301 is also included; the front part of the sliding plate 2 is fixedly connected with the silica gel block 301.

[0038] It also includes a pressure sensor 302; the pressure sensor 302 is fixedly connected inside the silicone block 301; and the pressure sensor 302 is connected to a power source.

[0039] The specific working steps are: When the sliding plate 2 moves forward, the front part of the sliding plate 2 is easy to hit the user's legs, thereby causing injuries to the user. Therefore, a silicone block 301 is set at the front part of the sliding plate 2 to prevent the front part of the sliding plate 2 from directly and rigidly contacting the user's legs, thereby causing injuries to the user. After the silicone block 301 contacts the user, the silicone block 301 will be squeezed and deformed. At this time, the deformed silicone block 301 will squeeze the pressure sensor 302, thereby sending an electrical signal to control the electric wheel 4 to stop driving the sliding plate 2 to move, thereby avoiding continued forward pushing and causing discomfort to the user. When the user leaves from the front side of the sliding plate 2 to avoid the sliding plate 2 moving forward, the silicone block 301 recovers its deformation and releases the squeezing of the pressure sensor 302, thereby controlling the electric wheel 4 again to drive the sliding plate 2 to move forward. By setting the silicone block 301 and the pressure sensor 302, injuries and discomfort to the user are avoided, and the user's service experience is improved.
