Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of lifting tables, and specifically relates to an intelligent electric lifting table with a face recognition function and an adjustment method thereof. Background Art
[0002] An electric lift table is a table that can adjust the height of the desktop through electric drive. It is widely used in homes, personal offices and corporate office environments to help users achieve sit-stand work, thereby preventing various health problems caused by long-term sitting. With its adjustable height, electric drive, diversified design and rich additional functions, the electric lift table has become a must-have artifact in modern office and home environments. By reasonably choosing and using an electric lift table, we can effectively prevent health problems caused by long-term sitting and improve work efficiency and quality of life.
[0003] Common electric lift tables are mainly divided into single-motor and dual-motor types. The motor drives the screw to rotate with the gear to achieve the lifting of the desktop. The single-motor lift table has limited load-bearing capacity. Although the cost is low, the lifting process is more complicated. The dual-motor lift table has a higher load-bearing capacity, but the structure is more complicated and will occupy part of the space under the table. At the same time, the load-bearing at both ends of the desktop is different during lifting, and the overall stability has room for improvement.
[0004] At the same time, when an electric lift table is used in an office and needs to be changed by different users, the height of the lift table needs to be adjusted for each user. It cannot be automatically adjusted for different users, and the convenience of use is poor. Summary of the invention
[0005] The purpose of the present invention is to provide an intelligent electric lifting table with face recognition function and an adjustment method thereof to solve the problems raised in the above background technology.
[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent electric lifting table with a face recognition function, comprising a table top, a supporting assembly fixedly installed at the bottom end of the table top, a face recognition module fixedly installed in the middle of the rear end of the table top, a memory module fixedly installed at the bottom end of the face recognition module, a storage box fixedly installed at the rear end of the support assembly, a lifting rod is provided just above the storage box, a lifting assembly located inside the storage box is installed at the bottom end of the lifting rod, the lifting assembly is connected to the rear end of the support assembly, a guide groove is provided at the bottom end of the inner cavity of the storage box, the guide groove is movably engaged with the bottom end of the lifting assembly, a mounting seat is fixedly installed on one side of the storage box, a servo motor is fixedly installed on the inner side surface of the mounting seat, the output end of the servo motor is connected to one side of the lifting assembly, the output end of the face recognition module is electrically connected to the input end of the memory module, and the output end of the memory module is electrically connected to the input end of the servo motor.
[0007] Embodiment: When a user walks into the device, that is, when the face recognition module detects the user's face, a photo of the user's face is taken and compared with the face data stored in the memory module. When the comparison is successful, the corresponding height parameter can be called out and transmitted to the servo motor, and the servo motor runs to the specified height. If the comparison fails, no adjustment is made; At the same time, the operator can manually adjust the table top to the specified height through the servo motor, capture facial data through the face recognition module, and store it through the memory module, binding the facial data and the table top height parameters, waiting for the next call.
[0008] By utilizing the cooperation between the face recognition module, the memory module and the servo motor, the device can automatically adjust to the user's required height when detecting and identifying different users. The entire process is completed automatically, and the user does not need to make manual adjustments each time it uses it. It is extremely suitable for use in public office places, and can effectively reduce the number of adjustments, while improving ease of use and work efficiency.
[0009] As a further technical solution of the present invention, the support assembly includes two top plates connected to the left and right sides of the bottom end of the table top, and movable sleeves are fixedly installed on the front and back sides of the bottom end of the top plate.
[0010] As a further technical solution of the present invention, the support assembly also includes a bottom plate located at the bottom ends of the two top plates, and fixed sleeve rods are fixedly installed on both sides of the top end of the bottom plate, and the fixed sleeve rods are movably connected to the movable sleeve.
[0011] As a further technical solution of the present invention, the two movable sleeves located at the rear side are connected to the left and right sides of the lifting rod, and the bottom end of the storage box is connected to the top end of the bottom plate.
[0012] As a further technical solution of the present invention, a second fixed seat is fixedly installed on the rear side of the two second fixed seats on the front side near the top end, and a first fixed seat is fixedly installed on the front side of the two fixed sleeve rods on the rear side near the bottom end, and a telescopic rod is movably connected between the first fixed seat and the second fixed seat via a rotating shaft.
[0013] When the height of the table top is adjusted, the movable sleeve is displaced relative to the fixed sleeve. When the table top rises, the distance between the movable sleeve and the fixed sleeve increases, and the position of the second fixed seat also changes. At this time, the telescopic rod is lengthened to adapt to the change in the distance between the movable sleeve and the fixed sleeve. At the same time, the weight of the front end of the table top can be transmitted to the rear end of the table top through the telescopic rod, and the combination of the fixed sleeve and the movable sleeve always forms a triangle with the base plate and the telescopic rod to maintain stable support at various heights.
[0014] When the height of the table top is quickly adjusted by utilizing the lifting assembly, the stable lifting of the table top can be achieved through the cooperation between the movable sleeve and the fixed sleeve rod. At the same time, the weight of the front end of the table top can be evenly distributed to the rear end of the table top by changing the length of the telescopic rod and its rotation relative to the second fixed seat and the first fixed seat, thereby ensuring the stability of the top end of the table top. The triangle that is always formed can be used to provide stable support for the table top, thereby improving the structural stability of the table top.
[0015] As a further technical solution of the present invention, the lifting assembly includes a third fixed seat, the number of the third fixed seat is two, and it is fixedly installed on the left and right sides of the bottom end of the third fixed seat, and the end of the third fixed seat away from the lifting rod is movably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the third fixed seat is movably connected to a fourth fixed seat through a rotating shaft.
[0016] As a further technical solution of the present invention, a guide block is fixedly installed at the bottom end of the fourth fixed seat, the guide block is movably connected to the guide groove, and the guide block is displaced left and right relative to the guide groove.
[0017] As a further technical solution of the present invention, the lifting assembly also includes a screw rod, the middle part of which is fixedly sleeved with a limiting sleeve, the screw rod is movably connected to the storage box, and one side of the screw rod is connected to the output end of the servo motor.
[0018] As a further technical solution of the present invention, a thread groove is opened inside the guide block and is threadedly connected to the screw rod through the thread groove. The thread directions of the left and right ends of the outer side of the screw rod are opposite and the corresponding thread directions of the internal thread groove of the guide block are the same.
[0019] When the memory module transmits the corresponding height parameter information to the servo motor, or when the servo motor is manually operated, the servo motor can drive the screw to rotate. When the screw rotates, the two guide blocks can be relatively far away or relatively close under the action of the guide groove. When the two guide blocks are relatively close, the two connecting rods will deflect toward the middle and drive the third fixed seat at the top to rise, and finally drive the lifting rod to rise, and push the movable sleeve to rise through the lifting rod until the table top moves upward. Conversely, when the two guide blocks are relatively far away, the lifting rod will drop and finally drive the table top to move downward, completing the height adjustment process of the table top.
[0020] By arranging a lifting component on the rear side of the table top and through the cooperation between the lifting component and the supporting component, the stable lifting of the table top is achieved. At the same time, the bottom end of the table top does not occupy a large amount of space, and the overall space utilization rate is high. At the same time, only a single servo motor is required to complete the stable lifting of the table top. The overall structure is relatively simple. At the same time, with the cooperation of the supporting component, a larger bearing capacity can be achieved, stable lifting can be achieved, and production costs can be reduced.
[0021] A method for adjusting an intelligent electric lifting table with a face recognition function comprises the following steps: S1: When the user walks into the device and the face recognition module recognizes the user's face, it can be matched with the face stored in the memory module. After the match is completed, the corresponding lifting height can be obtained and the parameter information can be transmitted to the servo motor; S2: At this time, the servo motor starts and drives the screw to rotate. At this time, the two guide blocks can approach each other under the guidance of the guide groove. When the two are close to each other, the connecting rod deflects and drives the two third fixed seats to rise, and finally the lifting rod at the top rises; S3: When the lifting rod rises, it drives the movable sleeve at the rear end to move upward. At this time, the movable sleeve at the front end moves upward synchronously, and drives the top table board to rise. At the same time, due to the increase in the distance between the movable sleeve at the front end and the fixed sleeve at the rear end, the telescopic rod is stretched to complete the adjustment process and the support process at the same time.
[0022] The beneficial effects of the present invention are as follows: 1. The present invention realizes stable lifting of the table top by arranging a lifting component on the rear side of the table top and the cooperation between the lifting component and the supporting component. At the same time, the bottom end of the table top does not occupy a large amount of space, and the overall space utilization rate is high. At the same time, only a single servo motor is required to complete the stable lifting of the table top. The overall structure is relatively simple. At the same time, with the cooperation of the supporting component, a larger bearing capacity can be achieved, stable lifting can be achieved, and production costs can be reduced.
[0023] 2. When the height of the table top is quickly adjusted by utilizing the lifting assembly of the present invention, the stable lifting of the table top can be achieved through the cooperation between the movable sleeve and the fixed sleeve rod. At the same time, the weight of the front end of the table top can be evenly distributed to the rear end of the table top by changing the length of the telescopic rod and its rotation relative to the second fixed seat and the first fixed seat, thereby ensuring the stability of the top end of the table top. The triangle that is always formed can be used to provide stable support for the table top, thereby improving the structural stability of the table top.
[0024] 3. The present invention utilizes the cooperation between the face recognition module, the memory module and the servo motor so that the device can automatically adjust to the user's required height when detecting and identifying different users. The entire process is completed automatically without the user having to make manual adjustments each time the device is used. The device is extremely suitable for use in public office places and can effectively reduce the number of adjustments while improving ease of use and work efficiency.

[0029] The face recognition module 3 adopts a 3D binocular face recognition solution of model TX510, which has the function of dark light recognition. The memory module 4 adopts model HLK-TX510, which supports the storage of up to 1,000 face databases, and the comparison time is less than 1 second. It has extremely fast recognition speed and efficient memory ability.
[0030] Embodiment: When a user walks into the device, that is, when the face recognition module 3 detects the user's face, a photo of the user's face is taken and compared with the face data stored in the memory module 4. When the comparison is successful, the corresponding height parameter can be called out and transmitted to the servo motor 10, and the servo motor 10 runs to the specified height. If the comparison fails, no adjustment is made; At the same time, the operator can manually adjust the table top 1 to a specified height through the servo motor 10, and capture facial data through the face recognition module 3, and store and memorize it through the memory module 4, binding the facial data and the height parameters of the table top 1, waiting for the next call.
[0031] By utilizing the cooperation between the face recognition module 3, the memory module 4 and the servo motor 10, the device can automatically adjust to the user's required height when detecting and identifying different users. The entire process is completed automatically, and the user does not need to make manual adjustments each time it uses it. It is extremely suitable for use in public office places, and can effectively reduce the number of adjustments, while improving ease of use and work efficiency.
[0032] like Figure 1 and Figure 2 as well as Figure 3 and Figure 4 As shown, the support assembly 2 includes a top plate 201, and the number of the top plates 201 is two and they are connected to the left and right sides of the bottom end of the table board 1. The front and rear sides of the bottom end of the top plate 201 are fixedly installed with movable sleeves 204. The support assembly 2 also includes a bottom plate 202 located at the bottom ends of the two top plates 201, and the left and right sides of the top end of the bottom plate 202 are fixedly installed with fixed sleeve rods 203, and the fixed sleeve rods 203 are movably connected with the movable sleeves 204. The left and right sides of the lifting rod 6 are connected between the two movable sleeves 204 on the rear side, and the bottom end of the storage box 5 is connected to the top end of the bottom plate 202.

A telescopic rod 207 is movably connected between the first fixed seat 205 and the second fixed seat 206 through a rotating shaft.
[0033] When the height of the table top 1 is adjusted, the movable sleeve 204 is displaced relative to the fixed sleeve 203. When the table top 1 rises, the distance between the movable sleeve 204 and the fixed sleeve 203 increases, and the position of the second fixed seat 206 also changes. At this time, the telescopic rod 207 is lengthened to adapt to the change in the distance between the movable sleeve 204 and the fixed sleeve 203. At the same time, the weight of the front end of the table top 1 can be transmitted to the rear end of the table top 1 through the telescopic rod 207, and the combination of the fixed sleeve 203 and the movable sleeve 204 always forms a triangle with the base plate 202 and the telescopic rod 207 to maintain stable support at various heights.
[0034] When the height of the table top 1 is quickly adjusted by utilizing the lifting assembly 7, the table top 1 can be stably lifted and lowered through the cooperation between the movable sleeve 204 and the fixed sleeve rod 203. At the same time, the weight of the front end of the table top 1 can be evenly distributed to the rear end of the table top 1 through the change in the length of the telescopic rod 207 and its rotation relative to the second fixed seat 206 and the first fixed seat 205, thereby ensuring the stability of the top end of the table top 1. The triangle that is always formed can be used to provide stable support for the table top 1, thereby improving the structural stability of the table top 1.
[0035] like Figure 1and Figure 2 as well as Figure 6 and Figure 7 As shown, the lifting assembly 7 includes a third fixed seat 701, the number of the third fixed seat 701 is two, and they are fixedly installed at the left and right sides of the bottom end of the third fixed seat 701, the end of the third fixed seat 701 away from the lifting rod 6 is movably connected to the connecting rod 703 through a rotating shaft, and the end of the connecting rod 703 away from the third fixed seat 701 is movably connected to the fourth fixed seat 702 through a rotating shaft, and the bottom end of the fourth fixed seat 702 is fixedly installed with a guide block 704, and the guide block 704 is movably engaged with the guide groove 8. The guide block 704 is displaced left and right relative to the guide groove 8. The lifting assembly 7 also includes a screw rod 705. The middle part of the screw rod 705 is fixedly sleeved with a limiting sleeve 706. The screw rod 705 is movably connected to the storage box 5. One side of the screw rod 705 is connected to the output end of the servo motor 10. A thread groove is provided inside the guide block 704 and is threadedly sleeved with the screw rod 705 through the thread groove. The thread directions of the left and right ends of the outer side surface of the screw rod 705 are opposite and the thread directions of the corresponding internal thread grooves of the guide block 704 are the same.
[0036] Embodiment: When the memory module 4 transmits the corresponding height parameter information to the servo motor 10, or when the servo motor 10 is manually operated, the servo motor 10 can drive the screw rod 705 to rotate. When the screw rod 705 rotates, the two guide blocks 704 can be relatively far away or relatively close to each other under the action of the guide groove 8. When the two guide blocks 704 are relatively close to each other, the two connecting rods 703 will deflect toward the middle and drive the third fixed seat 701 at the top to rise, and finally drive the lifting rod 6 to rise, and push the movable sleeve 204 to rise through the lifting rod 6 until the table board 1 moves upward. On the contrary, when the two guide blocks 704 are relatively far away from each other, the lifting rod 6 will drop accordingly, and finally drive the table board 1 to move downward, completing the height adjustment process of the table board 1.
[0037] By arranging a lifting component 7 on the rear side of the table top 1 and through the cooperation between the lifting component 7 and the support component 2, the stable lifting of the table top 1 is achieved. At the same time, the bottom end of the table top 1 does not occupy a large amount of space, and the overall space utilization rate is high. At the same time, only a single servo motor 10 is required to complete the stable lifting of the table top 1. The overall structure is relatively simple. At the same time, with the cooperation of the support component 2, a larger bearing capacity can be achieved, stable lifting can be achieved, and production costs can be reduced.
[0038] A method for adjusting an intelligent electric lifting table with a face recognition function comprises the following steps: S1: When a user walks into the device and the face recognition module 3 recognizes the user's face, it can be matched with the face stored in the memory module 4. After the matching is completed, the corresponding lifting height can be obtained, and the parameter information is transmitted to the servo motor 10; S2: At this time, the servo motor 10 is started and drives the screw rod 705 to rotate. At this time, the two guide blocks 704 can approach each other under the guidance of the guide groove 8. When the two are close to each other, the connecting rod 703 deflects and drives the two third fixed seats 701 to rise, and finally the lifting rod 6 at the top rises; S3: When the lifting rod 6 rises, it drives the movable sleeve 204 at the rear end to move upward. At this time, the movable sleeve 204 at the front end moves upward synchronously, and drives the top table board 1 to rise. At the same time, due to the increase in the distance between the movable sleeve 204 at the front end and the fixed sleeve 203 at the rear end, the telescopic rod 207 is stretched to complete the adjustment process and the support process at the same time.
[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
