Description

Technical Field

[0001] This invention relates to the field of lifting platform technology, and more particularly to an electric lifting table and its control method. Background Technology

[0002] Electric height-adjustable desks are commonly used in homes and offices, such as height-adjustable desks, dining tables, and office desks. Current electric height-adjustable desks are equipped with a manual controller, which users typically use to operate the desk. However, this manual controller usually needs to be installed in a fixed location, requiring users to go to a specific spot to operate it, which is inconvenient and user-unfriendly. Furthermore, the manual controller is a component of the entire electric height-adjustable desk, incurring additional costs, thus increasing the overall cost of the desk. Summary of the Invention

[0003] One of the technical problems to be solved by the present invention is to provide an electric height-adjustable table that is more user-friendly and has a lower cost.

[0004] One technical solution adopted in this invention is: an electric height-adjustable desk, comprising:

[0005] A tabletop with at least one table leg on one side;

[0006] A lifting mechanism is installed inside the table leg;

[0007] A controller is connected to the tabletop, and the controller is electrically connected to the lifting mechanism;

[0008] It also includes:

[0009] A vibration sensor is electrically connected to the controller;

[0010] Furthermore, the vibration sensor detects the vibration of the tabletop caused by the user tapping the tabletop, and the controller controls the lifting mechanism to operate based on the user's tapping behavior detected by the vibration sensor.

[0011] Preferably, the vibration sensor is a multi-axis accelerometer.

[0012] Preferably, the vibration sensor is rigidly connected to the tabletop.

[0013] Compared with the prior art, the present invention has the following advantages by adopting the above structure: a vibration sensor is set to detect the vibration of the tabletop, and then the lifting mechanism is controlled according to different tabletop vibration conditions. In this way, the electric lifting table does not need to be equipped with a manual controller. Only a controller and a vibration sensor are needed to achieve convenient control, making the control more user-friendly. Moreover, eliminating the manual controller can greatly reduce costs.

[0014] Using a six-axis accelerometer as the vibration sensor results in better detection performance.

[0015] The vibration sensor is rigidly connected to the tabletop, which improves the detection results.

[0016] Another technical problem to be solved by the present invention is to provide a more user-friendly and lower-cost control method for electric height-adjustable desks.

[0017] Another technical solution adopted in this invention is: a control method for an electric height-adjustable desk, the electric height-adjustable desk comprising:

[0018] A tabletop with at least one table leg on one side;

[0019] A lifting mechanism is installed inside the table leg;

[0020] A controller is connected to the tabletop, and the controller is electrically connected to the lifting mechanism;

[0021] A vibration sensor is electrically connected to the controller;

[0022] The controller is configured to receive table vibrations from the user striking the table, which are sensed by the vibration sensor. The controller then controls the lifting mechanism based on the received table vibrations.

[0023] As a preferred method, the control method for an electric height-adjustable desk includes the following steps:

[0024] S1. Set the control method of the lifting mechanism corresponding to the different table vibration caused by different tapping methods of the user;

[0025] S2. After the electric height-adjustable desk is activated, the vibration sensor detects the vibration of the desk. If no vibration caused by the user's tap is detected, the system returns to step S2 to continue detecting. If the user's tap is detected, the vibration information is transmitted to the controller, and then the system jumps to step S3.

[0026] S3. The controller obtains the control mode of the corresponding lifting mechanism based on the table vibration information obtained in step S2 and the settings in step S1, and then controls the lifting mechanism according to the obtained control mode.

[0027] Preferably, the tabletop vibration caused by the user's tapping in step S1 is determined by detecting vibration parameters, which include the number of vibrations and / or frequency and / or force.

[0028] Preferably, step S1 also requires setting the table vibration settings for waking up the controller, and step S2 and above also includes the following steps:

[0029] S21. The vibration sensor detects tabletop vibration caused by user tapping. If the control method corresponding to the detected tabletop vibration is to wake up the controller, then the controller is woken up and the control of the electric height-adjustable table is activated. If the detected tabletop vibration does not correspond to waking up the controller, then the detection continues.

[0030] Preferably, if the vibration sensor does not detect any table vibration within a time interval X since the last control action, the controller will go into sleep mode and turn off the control of the electric height-adjustable table.

[0031] Preferably, in step S2, when table vibration is detected, it is necessary to continuously detect for a time Y, and then transmit the table vibration information detected within the time Y to the controller.

[0032] Preferably, in step S3, if the vibration sensor detects vibration of the tabletop when the controller controls the lifting mechanism to run, the controller will stop the lifting mechanism from running.

[0033] Compared with the prior art, the present invention has the following advantages by using the above method: a vibration sensor is set to detect the vibration of the tabletop, and then the lifting mechanism is controlled according to different tabletop vibration conditions. In this way, the electric lifting table does not need to be set with a manual controller. Only a controller and a vibration sensor are needed to achieve convenient control, making the control more user-friendly. Moreover, eliminating the manual controller can greatly reduce costs.

[0034] The lifting mechanism is controlled by setting the tabletop vibration conditions. The lifting mechanism is then controlled based on the tabletop vibration detected by the vibration sensor. This eliminates the need for a manual controller, making the control more user-friendly and convenient. Furthermore, the overall cost of the electric lifting desk is lower.

[0035] The lifting mechanism can be controlled by a combination or by adjusting the number of vibrations, frequency, and force, which provides high accuracy and a variety of control methods.

[0036] Set up a wake-up controller procedure so that when the controller is not woken up, tapping the table will not control the lifting mechanism, thus preventing accidental triggering.

[0037] Furthermore, if no vibration control is detected within a certain period after waking up, the controller will go into sleep mode, which can also prevent accidental triggering.

[0038] After detecting vibration on the tabletop, it is necessary to continue monitoring for a period of time to prevent incorrect judgments due to short monitoring time.

[0039] When the controller is in a wake-up state and is controlling the lifting mechanism to operate, i.e., rising or falling, if table vibration is detected, the lifting mechanism will stop. This makes the control more convenient and user-friendly. Attached Figure Description

[0042] As shown in the figure: 1. Tabletop; 2. Table legs; 3. Controller. Detailed Implementation

[0043] The present invention will be further described below through specific embodiments, but the present invention is not limited to the following specific embodiments.

[0044] An electric height-adjustable desk includes a tabletop 1, table legs 2 disposed on both sides of the tabletop 1, a lifting mechanism disposed inside the table legs 2, a controller 3 connected to the tabletop 1, and a vibration sensor disposed on the tabletop 1, wherein:

[0045] Tabletop 1 is generally a flat surface, which is a feature of most existing height-adjustable desks, so it will not be discussed in detail here.

[0046] Table legs 2 generally consist of two parts, and the two parts can extend and retract, which is a standard feature of existing height-adjustable tables and will not be discussed in detail here.

[0047] The lifting mechanism is usually located inside the table legs and is used to control the extension and retraction of the table legs, thereby controlling the height of the lifting table. It is electrically connected to the controller and is mostly a motor. This is also the standard setting for existing lifting tables and will not be elaborated on in detail.

[0048] A vibration sensor is used to detect the vibration of the tabletop. It is electrically connected to the controller and rigidly connected to the tabletop. In this specific embodiment, a single-axis or multi-axis accelerometer is mainly selected. The accelerometer detects vibration by detecting the rapid change of gravitational acceleration in the vertical direction. Since the commonly used six-axis accelerometer is available on the market, it will not be discussed in detail here.

[0049] Controller 3 controls the operation of the lifting mechanism and receives information on the table vibration transmitted from the vibration sensor. This is a standard setting for existing height-adjustable desks and will not be elaborated on here.

[0050] A control box is installed under the tabletop 1. The controller 3 is installed inside the control box, while the vibration sensor can be installed in the control box together with the controller 3, or it can be installed separately under the tabletop.

[0051] Specific Implementation Method 1: The control method for the above-mentioned electric height-adjustable desk includes the following steps:

[0052] First, it is necessary to set the specific control methods for the table vibration and the lifting mechanism. In this specific embodiment, two taps are set to wake up the controller. When the controller is in the wake-up state, one tap raises the lifting mechanism, and two taps lower the lifting mechanism. When the controller is in the raising or lowering state, as long as the vibration sensor detects vibration on the table, it directly controls the lifting mechanism to stop moving. The vibration sensor detection corresponding to the tap is the vibration, that is, two taps are equivalent to two vibrations.

[0053] Next, the electric height-adjustable desk needs to be powered on and started. When the desk is detected to have been tapped twice, the controller is activated, and the electric height-adjustable desk is then activated. This is because a specific tapping vibration is required to activate the controller and thus activate the electric height-adjustable desk. Moreover, within a certain time period (X is generally set to 0.5-1 minute; in this specific embodiment, X is set to 1 minute), if the vibration sensor does not detect any vibration on the desk, the controller will go into sleep mode, and the electric height-adjustable desk will be deactivated. This means that once the controller is activated, any subsequent detected desk vibrations will be caused by the user tapping the desk, rather than by other forms of accidental triggering, such as the desk encountering an obstacle or a heavy object being placed on the desk. These situations generally only produce one vibration, not two, so they will not activate the controller and thus the electric height-adjustable desk will not be activated.

[0054] When the controller is activated and the electric height-adjustable desk is turned on, the vibration sensor continues to detect. If the desk is hit once (i.e., the desk vibrates once), the controller controls the lifting mechanism to rise. If the desk is hit again during the rising process (i.e., the desk vibrates twice), the controller controls the lifting mechanism to descend. If the desk is hit again during the descending process (i.e., the desk vibrates twice), the controller controls the lifting mechanism to descend.

[0055] The term "one tap" refers to a situation where, when the controller is awake, the vibration sensor detects vibration of the tabletop and continues to detect for a duration of Y. However, during this period, the vibration sensor does not detect any further vibration of the tabletop. This is called a "one tap." The term "two taps" refers to a situation where, when the controller is awake, the vibration sensor detects vibration of the tabletop and continues to detect for a duration of Y. During this duration, the vibration sensor detects another vibration of the tabletop. This is called a "two taps." The duration of Y is generally set to 0.1-3 seconds, and in this specific embodiment, it is set to 2 seconds.

[0056] Specific Implementation Example 2 differs from Specific Implementation Example 1 in that the set tabletop vibration conditions and control methods are different. Specific Implementation Example 2 primarily uses the intensity of the tapping as the judgment standard. When the tapping force is relatively heavy, i.e., the tapping force is between B and C, the controller is first activated. After activation, the controller continues to detect. If the detected tapping force is relatively light, i.e., the tapping force is between A and B, the lifting mechanism is controlled to rise. If a tapping is detected during the rising process, the lifting mechanism is controlled to stop rising. If the detected tapping force is relatively heavy, i.e., the force is between B and C, the lifting mechanism is controlled to descend. If a tapping is detected during the descending process, the lifting mechanism is controlled to stop descending. The vibration sensor detecting the tapping is the vibration itself; one tap equals one vibration.

[0057] The difference between Specific Embodiment Three and Specific Embodiments One and Two lies in the setting of the table vibration and the specific control method. Specific Embodiment Three mainly uses the frequency of the tapping as the judgment standard, that is, the speed of the tapping. When the tapping is fast, that is, the tapping frequency is greater than D, the controller is first awakened. After the controller is awakened, it continues to detect. If the detected tapping frequency is slow, that is, the tapping frequency is less than or equal to D, the controller controls the lifting mechanism to rise. If a tapping is detected during the rising process, the lifting mechanism is controlled to stop rising. If the detected tapping frequency is fast, that is, the tapping frequency is greater than D, the lifting mechanism is controlled to descend. If a tapping is detected during the descending process, the lifting mechanism is controlled to stop descending.

[0058] The difference between Specific Embodiment Four and Specific Embodiment One is that Specific Embodiment Four not only controls the lifting mechanism to rise, fall, or stop, but also controls the lifting mechanism to move to a set position. For example, when controlling it, three taps will control the lifting mechanism to move to the first set position, and four taps will control the lifting mechanism to move to the second set position. The principle for judging three taps and four taps is similar to the principle for one tap and two taps in Specific Embodiment One.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
