Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0039] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0040] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] See also Figures 1 to 10As shown; the embodiment of the present application discloses an electric lifting floor stand, which is placed on the ground and is used to carry an electrical accessory 5, wherein the electrical accessory 5 includes one of a hair dryer, a mobile phone, a camera, a video camera, a handheld vacuum cleaner, a microphone, etc.; the electric lifting floor stand of the present embodiment has a structure including a base 1, a lifting assembly 2, a first electric drive assembly 6 and a mounting frame 3 for mounting the power supply accessory 5, wherein the lower end of the lifting assembly 2 is connected to the base 1, the upper end of the lifting assembly 2 is connected to the mounting frame 3, and the lifting assembly 2 is used to adjust the height of the mounting frame 3 relative to the base 1. Specifically in the present embodiment, the lifting assembly 2 includes a fixed rod 200 connected to the base 1 and a movable rod 201 that slides axially relative to the fixed rod 200; the first electric drive assembly 6 is transmission-connected to the lifting assembly 2, and is used to drive the lifting assembly 2 to rise and fall; the mounting frame 3 is rotationally connected to the lifting assembly 2, and can be synchronously lifted and lowered with the lifting assembly 2.

[0043] In this embodiment, the first electric drive component 6 drives the lifting component 2 to lift and lower, which can make the mounting frame 3 rise and fall synchronously. Therefore, when the user is in use, the height of the floor bracket can be electrically adjusted, so that the height of the electrical accessories 5 on the mounting frame 3 can be adjusted to meet the needs of users of different heights and facilitate user use.

[0044] In the above embodiment, the first electric drive assembly 6 is connected to the lifting assembly 2 and can be raised and lowered synchronously with the lifting assembly 2; Figure 1 , Figure 2 and Figure 3 As shown, the upper end of the lifting assembly 2, that is, the upper end of the movable rod 201 is connected to the housing 4, and the first electric drive assembly 6 includes a first drive motor 600 connected to the housing 4, a screw rod 601 drivingly connected to the first drive motor 600, and a transmission nut 602 threadedly connected to the screw rod 601, and the transmission nut 602 is connected to the fixed rod 200. The first drive motor 600 drives the screw rod 601 to rotate, and when the transmission nut 602 is circumferentially limited by the fixed rod 200, the screw rod 601, the first drive motor 600 and the movable rod 201 move synchronously relative to the fixed rod 200 to achieve the lifting and lowering of the lifting assembly 2.

[0045] In the above-mentioned embodiment, the fixed rod 200 and the movable rod 201 are both hollow rods, and the movable rod 201 is axially slidably sleeved and circumferentially limited on the fixed rod 200, the screw rod 601 is rotatably connected in the center hole of the fixed rod 200, and the transmission nut 602 is connected in the fixed rod 200. That is, the screw rod 601 and the transmission nut 602 of the first electric drive assembly 6 are arranged in the lifting assembly 2, and the transmission nut 602 is connected to the fixed rod 200, so that the fixed rod 200 limits the circumferential rotation of the transmission nut 602, and when the first drive motor 600 drives the screw rod 601 to rotate, under the action of the transmission nut 602, the screw rod 601 moves axially.

[0046] Furthermore, the movable rod 201 is axially slidably sleeved and circumferentially limited on the fixed rod 200. For example, a coaxially arranged connecting sleeve is connected to the upper end of the fixed rod 200, and the outer wall of the connecting sleeve is axially provided with a plurality of guide ribs, and the inner wall of the movable rod 201 is axially provided with a plurality of guide grooves that are respectively matched with the guide ribs for sliding insertion. With the cooperation of the guide grooves and the guide ribs, the movable rod 201 is circumferentially limited on the fixed rod 200, and the movable rod 201 can be axially retracted relative to the fixed rod 200.

[0047] It is understandable that the manner in which the movable rod 201 is limited to rotate relative to the fixed rod 200 in the embodiment of the present application is only an example, and in other alternative embodiments, for example, a guide rib may be provided on the inner wall of the movable rod 201, and a guide groove may be provided on the outer wall of the fixed rod 200. The present application does not impose any special restrictions on the manner in which the movable rod 201 is limited to rotate relative to the fixed rod 200, as long as the purpose of enabling the movable rod 201 to move up and down relative to the fixed rod 200 under the drive of the first drive motor 600 can be met.

[0048] In other embodiments, the first electric drive component may also be an electric push rod or a linear motor, that is, the main body of the electric push rod or the linear motor and the movable part that can be axially retracted relative to the main body are respectively connected to the movable rod and the fixed rod.

[0049] Further in other embodiments, the first drive motor 600 of the first electric drive assembly 6 can also be set on the base 1 or in the fixed rod 200, the screw rod 601 is rotatably connected in the fixed rod 200, and the transmission nut 602 is connected to the movable rod 201.

[0050] In order to facilitate the adjustment of the left and right swing angle of the mounting frame 3 relative to the lifting assembly 2, in this embodiment, a second electric drive assembly is connected to the lifting assembly 2, and the second electric drive assembly is in transmission connection with the mounting frame 3, and is used to drive the mounting frame 3 to swing left and right in the horizontal direction relative to the lifting assembly 2 to adjust the angle. The left and right swing of the mounting frame 3 in the horizontal direction can make the orientation or horizontal position of the electrical accessories 5 on the mounting frame 3 adjustable. The electric lifting floor stand drives the rotation of the mounting frame 3 through the second electric drive assembly, so that the left and right swing angle of the mounting frame 3 in the horizontal direction can be electrically adjusted, which is convenient for users to use. Therefore, the electric lifting floor stand can not only automatically adjust the height, but also automatically adjust the left and right swing angle of the mounting frame 3, which is convenient to use and provides a good user experience.

[0051] In this embodiment, see Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the movable rod 201 of the lifting assembly 2 is connected to a housing 4, and the second electric drive assembly includes a second drive motor 7 connected to the housing 4. The second drive motor 7 is connected to the mounting frame 3 in a transmission connection, and is used to drive the mounting frame 3 to swing left and right in the horizontal direction to adjust the angle. The second drive motor 7 can drive the mounting frame 3 to rotate when working, so that the mounting frame 3 swings left and right, so that the horizontal orientation or horizontal deflection angle of the electrical accessories 5 on the mounting frame 3 can be adjusted. Specifically in this embodiment, the second drive motor 7 is vertically arranged in the housing 4, and the mounting frame 3 has a vertically arranged connecting shaft 300, and the connecting shaft 300 is connected to the rotating shaft of the second drive motor 7. When the rotating shaft of the second drive motor 7 drives the connecting shaft 300 of the mounting frame 3 to rotate, the mounting frame 3 rotates accordingly, so that the left and right swing angle of the mounting frame 3 in the horizontal direction can be adjusted. In addition, the second drive motor 7 is vertically arranged in the housing 4, so that the volume of the housing 4 can be set smaller, and the axis of the second drive motor 7 coincides or substantially coincides with the axis of the lifting assembly 2, so that the electric lifting floor stand has good standing stability and is not easy to tip over.

[0052] In order to facilitate the user to assemble or disassemble the mounting bracket 3, see Figure 4 and Figure 5 As shown, in this embodiment, a connector 700 extending upward from the top of the housing is coaxially connected to the rotating shaft of the second drive motor 7, and the connecting shaft 300 is detachably connected to the connector 700. The connector 700 of this embodiment is also called a coupling, the lower end of which is plugged and fixed on the rotating shaft of the second drive motor 7, and the upper end of which is connected to the connecting shaft 300 of the mounting frame 3; the connecting shaft 300 is arranged to extend upward from the top of the housing, so that it is convenient for users to assemble the connecting shaft 300 of the mounting frame 3 with the connector 700, thereby improving assembly efficiency.

[0053] In the aforementioned embodiment, it can be understood that when the product is packaged before leaving the factory, the mounting frame 3 can be removed and packaged independently to avoid occupying more packaging space, save packaging costs, and prevent the mounting frame 3 from being damaged due to squeezing; of course, when the user assembles, it is only necessary to connect the connecting shaft 300 of the mounting frame 3 to the connector 700 to easily complete the assembly of the mounting frame 3.

[0054] In order to further realize the rapid assembly of the mounting frame 3, see Figure 4 and Figure 5As shown, a plug hole 308 is formed in the center of the lower end of the connecting shaft 300, and the upper end of the connector 700 is plugged into the plug hole 308. A fastener is connected to the connecting shaft 300 to fasten the connecting shaft 300 and the connector 700. Therefore, when assembling the mounting frame 3, the plug hole 308 on the connecting shaft 300 of the mounting frame 3 is aligned and plugged into the upper end of the connector 700, and then the fastener on the connecting shaft 300 is tightened. Under the locking action of the fastener, the connector 700 and the connecting shaft 300 are fixed more firmly.

[0055] In the aforementioned embodiment, in order to prevent the second drive motor 7 from suddenly rotating, the torque transmitted by the connector 700 to the connecting shaft 300 is greater than the locking force of the fastener, causing the connector 700 to rotate relative to the connecting shaft 300; in the aforementioned embodiment, a limiting groove 309 is axially provided in the plug-in hole 308 of the connecting shaft 300, and a limiting protrusion 701 inserted into the limiting groove 309 is provided on the connector 700; under the circumferential limitation of the limiting groove 309 and the limiting protrusion 701, the connector 700 and the connecting shaft 300 can maintain synchronous rotation.

[0056] In other embodiments, a limiting protrusion may be provided in the plug-in hole of the connecting shaft along the axial direction, and a limiting groove that matches and plugs with the limiting protrusion may be provided on the connector.

[0057] In some embodiments, a plug-in slot may also be provided at the upper end of the connector, so that the connecting shaft on the mounting frame is plugged into the plug-in slot at the upper end of the connector and locked by a fastener.

[0058] In some embodiments, see Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the mounting bracket 3 further includes a connecting arm 301 and a connecting seat 303 connected to the power supply accessory 5, the first end of the connecting arm 301 is rotatably connected to the connecting shaft 300, and the second end of the connecting arm 301 is rotatably connected to the connecting seat 303. That is, the connecting arm 301 can rotate an angle relative to the connecting shaft 300, and the connecting seat 303 can also rotate an angle relative to the connecting arm 301, so that the angle adjustment of the electrical accessory 5 on the connecting seat 303 is more flexible and convenient, and is convenient for users to use.

[0059] It can be understood that, in the above embodiment, the first end of the connecting arm 301 is rotatably connected to the connecting shaft 300, and the second end of the connecting arm 301 is rotatably connected to the connecting seat 303; in order to keep the connecting arm 301 and the connecting seat 303 in a fixed position after rotating to a certain angle, a soft elastic friction pad can be provided at the rotational connection between the connecting arm 301 and the connecting shaft 300 and the connecting arm 301 and the connecting seat 303, so as to utilize friction force to maintain the angular position after rotation.

[0060] Further in this embodiment, see Figure 6 and Figure 7 As shown, a ball head 302 is provided at the first end of the connecting arm 301, and a concave arc-shaped ball head seat is provided at the upper end of the connecting shaft 300. The ball head 302 is universally rotatably connected to the ball head seat of the connecting shaft 300; thus, the mounting frame 3 can be universally adjusted relative to the lifting assembly 2 or the shell 4, bringing convenience to the user.

[0061] In the above-mentioned embodiment, the upper end of the connecting shaft 300 is provided with a positioning notch 310 which is connected to the ball head seat and is provided for accommodating the connecting arm 301. When the connecting arm 301 is accommodated in the positioning notch 310, the positioning notch 310 allows the connecting arm 301 to be fixed in the horizontal direction relative to the connecting shaft 300. When adjusting the horizontal swing angle of the mounting frame 3, the connecting arm 301 of the mounting frame 3 is accommodated in the notch 310 of the connecting shaft 300, so that the connecting arm 301 is kept fixed in the horizontal direction, which facilitates the adjustment of the left and right swing angles in the horizontal direction. In addition, the provision of the notch 310 makes it difficult for the connecting arm 301 to shake when rotating, and the structural stability is good.

[0062] In some embodiments, when the connecting arm 301 is accommodated in the positioning notch 310, the axis of the connecting arm 301 is perpendicular to the axis of the connecting shaft 300, that is, when the connecting arm 301 is accommodated in the positioning notch 310, the connecting arm 301 is horizontally arranged, which is convenient for swinging in the horizontal direction to adjust the angle.

[0063] In some embodiments, see Figure 7 and Figure 8 As shown, the connection base 303 has a socket 304 for plugging in the power supply accessory 5, and the connection base 303 is provided with an opening 305 connected to the socket 304; a cam wrench 306 is rotatably connected to the connection base 303 on one side of the opening 305, and the cam portion of the cam wrench 306 is connected to the connection base 303 on the other side of the opening 305, and is used to adjust the size of the opening 305 so that the socket 304 clamps or loosens the electrical accessory 5. The arrangement of the connection base 303 makes the installation and removal of the electrical accessory 5 simple and convenient. Specifically, taking a hair dryer as an example, the hair dryer is plugged into the socket 304 of the connecting seat 303, and then the cam wrench 306 is rotated. The cam portion of the cam wrench 306 squeezes the connecting seat 303 on both sides of the opening 305, thereby making the opening 305 smaller and clamping the hair dryer in the socket 304. Conversely, by rotating the cam wrench 306 in the opposite direction, the cam portion of the cam wrench 306 can release the squeezing of the connecting seat 303 on both sides of the opening 305, thereby releasing the socket 304 from the hair dryer, making it easier to remove the hair dryer.

[0064] For example, see Figure 7 and Figure 8As shown, the connection seat 303 is circular in shape as a whole, and the opening 305 is connected to the insertion hole 304 of the connection seat 303. A concave recess 307 is provided on the connection seat 303 on the first side of the opening 305, and a cam spanner 306 is rotatably connected to the first side of the opening 305. A connecting hole is provided on the second side of the opening 305, and a pull rod 311 is connected to the connecting hole, and the outer end of the pull rod 311 is axially limited in the connecting hole, and the inner end of the pull rod 311 is rotatably connected to the cam portion of the cam spanner 306. When the cam spanner 306 rotates, the cam portion of the cam spanner 306 can tighten or release the second side of the opening 305 through the pull rod 311, so that the width of the opening 305 changes, so that the insertion hole 304 clamps or loosens the hair dryer or other electrical accessories 5 in the insertion hole 304. When the cam spanner 306 rotates to a locked state, the recess 307 on the connection seat 303 can be accommodated in the recess 307 to prevent accidental rotation and opening.

[0065] In some embodiments, see Figure 3 and Fig. 9 As shown, a power supply 401 and a control unit 402 are connected in the housing 4, the power supply 401 is electrically connected to the control unit 402, and the control unit 402 is electrically connected to the first electric drive assembly 6 and the second drive motor 7 respectively. The control unit 402 includes a control circuit board and a control panel, the control circuit board is installed in the housing 4, and the control panel is installed on the surface of the housing 4 and is electrically connected to the control circuit board, and is used to send control instructions to the control circuit board to realize the lifting control of the lifting assembly 2 and the left and right swing angle control of the mounting frame 3. This arrangement makes it very convenient and labor-saving to adjust the height of the electric lifting floor bracket and the left and right swing angle of the mounting frame 3.

[0066] The power source 401 in the above embodiment is configured as a charging power source, so that it is convenient for users to move and improves the convenience of use. Both the first drive motor 600 and the second drive motor 7 can be configured as DC motors.

[0067] In this embodiment, if the control unit 402 is plugged in to obtain power, a power adapter may also be provided on the plugged-in power source 401 line.

[0068] Further in the aforementioned embodiment, the electric lifting floor stand further includes a remote controller, which communicates with the control unit 402 and is used to send control instructions to the control unit 402. The remote controller communicates with the control unit 402, and the first electric drive assembly 6 and the second electric drive assembly can be controlled by the remote controller to adjust the height of the lifting assembly 2 and adjust the left and right swing angle of the mounting frame 3. Therefore, the setting of the remote controller enables the user to achieve remote control, which is convenient for the user to use.

[0069] In this embodiment, see Figure 1 , Figure 2 and Fig.10As shown, the base 1 includes a central seat 101 and a plurality of legs 100. A connection portion for connecting the fixing rod 200 is provided at the top of the central seat 101, and the connection portion is a plug or a socket 304 provided at the center of the top of the central seat 101. The plurality of legs 100 are distributed along the circumference of the central seat 101 and are rotatably connected to the central seat 101. With such a configuration, when the product is packaged at the factory, the legs 100 can be rotated to be folded up to save packaging space and reduce packaging costs; when in use, each leg 100 only needs to be rotated to be opened, so it is very convenient to use.

[0070] It can be understood that the lifting assembly 2 of the electric lifting floor stand is connected to the first drive motor 600 and the second drive motor 7, which are generally heavy, and when the motor rotates, it is bound to vibrate to a certain extent. Therefore, the electric lifting floor stand has a high requirement for the stability of the base 1. In this embodiment, see Fig.10 As shown, the base 1 also includes a base 102. When the legs 100 rotate relative to the center seat 101 to the unfolded state, the base 102 is connected to the bottom of the center seat 101 and respectively abuts against the bottom of the legs 100, so as to keep the legs 100 in the unfolded state. That is, after each leg 100 rotates and unfolds, the base 102 is connected to the bottom of the center seat 101 by screws, and the upper end of the base 102 abuts against the bottom of the legs 100 and is pressed tightly, which can not only effectively prevent the legs 100 from rotating accidentally, but also make up for the rotation gap between the legs 100 and the center seat 101, so that the legs 100 have better standing stability, thereby effectively preventing the base 1 from shaking.

[0071] Further in this embodiment, the base 102 is connected to a plurality of supporting legs 103 along the circumferential direction, which correspond to the supporting legs 100 one by one and are located at the bottom of the supporting legs 100. Fig.10 As shown, a plurality of outwardly protruding connecting blocks 104 are provided in the circumference of the base 102, and the number and position of the connecting blocks 104 correspond to the supporting legs 100 one by one, and the supporting legs 103 are connected to the connecting blocks 104 by screws; the provision of the supporting legs 103 can prevent the supporting legs 100 from shaking up and down due to the load-bearing, thereby further improving the standing stability of the base 1.

[0072] For example, see Fig.10As shown, the center seat 101 is circumferentially connected to three legs 100, and a base 102 is connected to the bottom of the center seat 101 by screws or bolts. Three connecting blocks 104 corresponding to the three legs 100 are arranged around the base 102, and each connecting block 104 is connected to a supporting foot 103 by screws. The supporting foot 103 is extended along the length direction of the supporting foot 100, and the top of the supporting foot 103 is against the bottom of the supporting foot 100; when the base 1 stands, the three supporting feet 103 touch the ground and the lower ends of the three supporting feet 100 touch the ground; this arrangement makes the base 1 have high standing stability.

[0073] In some embodiments, see again Figure 1 , Figure 4 and Figure 5 As shown, the housing 4 is provided with a hanging hole 400 for hanging a hanging part. The hanging hole 400 can be convenient for hanging items, thereby improving its storage capacity. Specifically in this embodiment, the hanging hole 400 is set as a gourd hole with a large top and a small bottom, so as to facilitate the quick hanging of the hanging column and improve the convenience of use.
