[0041] The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0042] Reference Figures 1-10The embodiment of the present application discloses an electric lifting floor stand which is placed on the ground and used for carrying an electric accessory 5, wherein the electric accessory 5 comprises one of a hair dryer, a mobile phone, a camera, a video camera, a handheld vacuum cleaner, a microphone and the like. The electric lifting floor stand of the embodiment comprises a base 1, a lifting assembly 2, a first electric driving assembly 6 and a mounting rack 3 used for mounting the electric accessory 5, wherein the lower end of the lifting assembly 2 is connected with the base 1, the upper end of the lifting assembly 2 is connected with the mounting rack 3, and the lifting assembly 2 is used for adjusting the height of the mounting rack 3 relative to the base 1. In the embodiment, the lifting assembly 2 comprises a fixed rod 200 connected with the base 1 and a movable rod 201 which slides along the axis relative to the fixed rod 200. The first electric driving assembly 6 is in transmission connection with the lifting assembly 2 and is used for driving the lifting assembly 2 to lift. The mounting rack 3 is rotationally connected with the lifting assembly 2 and can lift synchronously with the lifting assembly 2.

[0043] In the embodiment, the first electric driving assembly 6 drives the lifting assembly 2 to lift, so that the mounting rack 3 can lift synchronously. Therefore, the user can electrically adjust the height of the floor stand when using, so that the height of the electric accessory 5 on the mounting rack 3 can be adjusted to meet the needs of users with different heights and facilitate the user to use.

[0044] In the above embodiment, the first electric driving assembly 6 is connected with the lifting assembly 2 and can lift synchronously with the lifting assembly 2. Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , the upper end of the lifting assembly 2, that is, the upper end of the movable rod 201 is connected with a shell 4. The first electric driving assembly 6 comprises a first driving motor 600 connected in the shell 4, a lead screw 601 in transmission connection with the first driving motor 600 and a transmission nut 602 screwed on the lead screw 601. The transmission nut 602 is connected with the fixed rod 200. The first driving motor 600 drives the lead screw 601 to rotate. In the case that the transmission nut 602 is limited in the circumferential direction by the fixed rod 200, the lead screw 601, the first driving motor 600 and the movable rod 201 move synchronously relative to the fixed rod 200 to realize the lifting of the lifting assembly 2.

[0045] In the foregoing embodiment, the fixed rod 200 and the movable rod 201 are both hollow rod members, and the movable rod 201 is slidably sleeved on the fixed rod 200 in the axial direction and is limited in the circumferential direction. The lead screw 601 is rotationally 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 lead screw 601 and the transmission nut 602 of the first electric driving assembly 6 are arranged in the lifting assembly 2, and the transmission nut 602 is connected with the fixed rod 200. Therefore, the fixed rod 200 limits the circumferential rotation of the transmission nut 602. When the first driving motor 600 drives the lead screw 601 to rotate, the lead screw 601 moves in the axial direction under the action of the transmission nut 602.

[0046] Further, the movable rod 201 is sleeved and axially limited on the fixed rod 200, for example, a coaxial connecting sleeve is connected to the upper end of the fixed rod 200, the outer wall of the connecting sleeve is provided with a plurality of guide protrusions in the axial direction, and the inner wall of the movable rod 201 is provided with a plurality of guide grooves respectively matched with the guide protrusions for sliding insertion, under the cooperation of the guide grooves and the guide protrusions, the movable rod 201 is circumferentially limited on the fixed rod 200, and the movable rod 201 can axially extend and retract relative to the fixed rod 200.

[0047] It can be understood that the way of limiting the rotation of the movable rod 201 relative to the fixed rod 200 in the embodiment of the application is only an example, in other alternative embodiments, for example, guide protrusions can also be provided on the inner wall of the movable rod 201, and guide grooves can be provided on the outer wall of the fixed rod 200. The application does not specially limit the way of limiting the rotation of the movable rod 201 relative to the fixed rod 200, as long as the purpose of the movable rod 201 moving up and down relative to the fixed rod 200 under the driving of the first driving motor 600 can be met.

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

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

[0050] In order to conveniently adjust the left and right swing angle of the mounting rack 3 relative to the lifting assembly 2, in the embodiment, a second electric driving assembly is connected to the lifting assembly 2, which is in transmission connection with the mounting rack 3 and is used to drive the mounting rack 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 rack 3 in the horizontal direction can adjust the orientation or horizontal position of the electrical accessory 5 on the mounting rack 3. The electric lifting floor stand drives the rotation of the mounting rack 3 through the second electric driving assembly, so that the angle of the mounting rack 3 swinging left and right 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 rack 3, which is convenient for users to use and has good user experience.

[0051] In the embodiment, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the movable rod 201 of the lifting assembly 2 is connected with the shell 4, the second electric driving assembly includes a second driving motor 7 connected with the shell 4, and the second driving motor 7 is in transmission connection with the mounting rack 3 and is used for driving the mounting rack 3 to swing left and right in the horizontal direction to adjust the angle. The second driving motor 7 can drive the mounting rack 3 to rotate when working, so that the mounting rack 3 swings left and right, and thus the horizontal orientation or horizontal deflection angle of the electric appliance accessory 5 on the mounting rack 3 can be adjusted. In the embodiment, the second driving motor 7 is vertically arranged in the shell 4, the mounting rack 3 has a vertically arranged connecting shaft 300, and the connecting shaft 300 is connected with the rotating shaft of the second driving motor 7. When the rotating shaft of the second driving motor 7 drives the connecting shaft 300 of the mounting rack 3 to rotate, the mounting rack 3 rotates, so that the left and right swing angle of the mounting rack 3 in the horizontal direction can be adjusted. In addition, the second driving motor 7 is vertically arranged in the shell 4, so that the volume of the shell 4 can be smaller, and the axis of the second driving motor 7 coincides or basically coincides with the axis of the lifting assembly 2, so that the standing stability of the electric lifting floor stand is good and is not easy to fall.

[0052] In order to facilitate the user to assemble or disassemble the mounting rack 3, referring to Figure 4 and Figure 5 As shown, in the embodiment, the rotating shaft of the second driving motor 7 is coaxially connected with a connector 700 extending upward from the top of the shell, and the connecting shaft 300 is detachably connected with the connector 700. The connector 700 of the embodiment is also called a shaft coupling, the lower end of which is inserted and fixed on the rotating shaft of the second driving motor 7, and the upper end of which is connected with the connecting shaft 300 of the mounting rack 3; the connecting shaft 300 is arranged to extend upward from the top of the shell, so that the user can easily assemble the connecting shaft 300 of the mounting rack 3 with the connector 700, and the assembly efficiency is improved.

[0053] In the foregoing embodiment, it can be understood that when the product is packaged for delivery, the mounting rack 3 can be taken down and packaged independently, so as to avoid occupying more packaging space, save packaging cost, and prevent the mounting rack 3 from being damaged due to extrusion; of course, when the user assembles, the mounting rack 3 can be easily assembled by only connecting the connecting shaft 300 of the mounting rack 3 with the connector 700.

[0054] In order to further realize the quick assembly of the mounting rack 3, referring to Figure 4 and Figure 5As shown in the drawings, a plug-in hole 308 is formed in the center of the lower end of the connecting shaft 300, the upper end of the connector 700 is plugged into the plug-in hole 308, and a fastener is connected to the connecting shaft 300 to fasten the connecting shaft 300 and the connector 700. Therefore, when the mounting rack 3 is assembled, the plug-in hole 308 on the connecting shaft 300 of the mounting rack 3 is aligned and plugged into the upper end of the connector 700, and then the fastener on the connecting shaft 300 is tightened, so that the connector 700 and the connecting shaft 300 are fixed more firmly under the locking action of the fastener.

[0055] In the foregoing embodiment, in order to prevent the connector 700 from rotating relative to the connecting shaft 300 when the second driving motor 7 suddenly rotates and the torque transmitted by the connector 700 to the connecting shaft 300 is greater than the locking force of the fastener, a limiting groove 309 is arranged in the plug-in hole 308 of the connecting shaft 300 in the axial direction, and a limiting protrusion 701 is arranged on the connector 700 and plugged into the limiting groove 309; under the circumferential limiting action of the limiting groove 309 and the limiting protrusion 701, the connector 700 and the connecting shaft 300 can be kept synchronous rotation.

[0056] In other embodiments, a limiting protrusion can also be arranged in the plug-in hole of the connecting shaft in the axial direction, and a limiting groove matched with the limiting protrusion is arranged on the connector.

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

[0058] In some embodiments, as shown in the drawings, Figure 4 , Figure 5 , Figure 6 and Figure 7 , the mounting rack 3 further comprises a connecting arm 301 and a connecting seat 303 for connecting the power accessory 5, the first end of the connecting arm 301 is rotationally connected to the connecting shaft 300, and the second end of the connecting arm 301 is rotationally connected to the connecting seat 303. That is, the connecting arm 301 can rotate at an angle relative to the connecting shaft 300, and the connecting seat 303 can also rotate at an angle relative to the connecting arm 301, so that the angle adjustment of the power accessory 5 on the connecting seat 303 is more flexible and convenient, and the user can use it more conveniently.

[0059] It can be understood that, in the above embodiment, the first end of the connecting arm 301 is rotationally connected to the connecting shaft 300, and the second end of the connecting arm 301 is rotationally connected to the connecting seat 303; in order to keep the connecting arm 301 and the connecting seat 303 fixed in position after rotating at a certain angle, a soft elastic friction pad can be arranged at the rotationally connected positions of the connecting arm 301 and the connecting shaft 300 and the connecting arm 301 and the connecting seat 303 to keep the angle position after rotation by using friction force.

[0060] Further in the embodiment, as shown in Figure 6 and Figure 7 , a ball head 302 is arranged at the first end of the connecting arm 301, and a concave arc-shaped ball head seat is arranged at the upper end of the connecting shaft 300, and the ball head 302 is connected with the ball head seat of the connecting shaft 300 in a universal manner; thus, the mounting rack 3 can be adjusted in a universal manner relative to the lifting assembly 2 or the shell 4, which brings convenience to the user.

[0061] In the foregoing embodiment, the upper end of the connecting shaft 300 is provided with a positioning gap 310 which is in communication with the ball head seat and is used for accommodating the connecting arm 301; when the connecting arm 301 is accommodated in the positioning gap 310, the positioning gap 310 fixes the position of the connecting arm 301 in the horizontal direction relative to the connecting shaft 300. When the horizontal swing angle of the mounting rack 3 is adjusted, the connecting arm 301 of the mounting rack 3 is accommodated in the gap 310 of the connecting shaft 300, so that the connecting arm 301 is fixed in position in the horizontal direction, which facilitates the adjustment of the left and right swing angles in the horizontal direction, and the gap 310 is arranged to prevent the connecting arm 301 from shaking during rotation, thus improving the structural stability.

[0062] In some embodiments, when the connecting arm 301 is accommodated in the positioning gap 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 gap 310, the connecting arm 301 is arranged in a horizontal manner, which facilitates the swing in the horizontal direction to adjust the angle.

[0063] In some embodiments, as shown in Figure 7 and Figure 8 , the connecting seat 303 is provided with a socket 304 for plugging the electric appliance accessory 5, and the connecting seat 303 is provided with an opening 305 which is in communication with the socket 304; the connecting seat 303 on one side of the opening 305 is rotatably connected with a cam wrench 306, and the cam portion of the cam wrench 306 is connected with the connecting seat 303 on the other side of the opening 305, which is used for adjusting the size of the opening 305 to clamp or release the electric appliance accessory 5. The arrangement of the connecting seat 303 makes the installation and removal of the electric appliance 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 presses the connecting seat 303 on both sides of the opening 305, so that the opening 305 becomes smaller, and the hair dryer in the socket 304 is clamped; conversely, the cam wrench 306 is rotated in the opposite direction, so that the cam portion of the cam wrench 306 releases the pressing of the connecting seat 303 on both sides of the opening 305, so that the socket 304 releases the hair dryer, which facilitates the removal of the hair dryer.

[0064] For example, as shown in Figure 7 and Figure 8As shown, the connecting seat 303 is circular as a whole, the opening 305 is communicated with the insertion hole 304 of the connecting seat 303, the first side of the opening 305 is provided with a concave recess 307 on the connecting seat 303, and the cam wrench 306 is rotationally connected to the first side of the opening 305, the second side of the opening 305 is provided with a connecting hole, the connecting hole is connected with the pull rod 311, the outer end of the pull rod 311 is axially limited in the connecting hole, the inner end of the pull rod 311 is rotationally connected with the cam portion of the cam wrench 306, when the cam wrench 306 is rotated, the cam portion of the cam wrench 306 can pull 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 releases the hair dryer or other electrical accessories 5 in the insertion hole 304. The recess 307 on the connecting seat 303 can be accommodated in the recess 307 when the cam wrench 306 is rotated to the locked state, so as to avoid accidental rotation and opening.

In this way, when the product is packaged for delivery, the legs 100 can be folded by rotating the legs 100 to save packaging space and reduce packaging cost; when in use, each leg 100 only needs to be rotated to be opened, so that the use is very convenient.

[0070] It can be understood that the lifting assembly 2 of the electric lifting floor stand is connected with the first driving motor 600 and the second driving motor 7, which generally have a heavy weight, and when the motors rotate, a certain vibration will inevitably occur, so that the stability of the base 1 of the electric lifting floor stand is required to be higher, and in the embodiment, as shown in the figure, Figure 10 As shown in the figure, the base 1 further comprises a base 102, when the legs 100 are rotated relative to the center seat 101 to the unfolded state, the base 102 is connected at the bottom of the center seat 101 and abuts against the bottom of the leg 100 respectively, for keeping the leg 100 in the unfolded state. That is, after each leg 100 is rotated and unfolded, the base 102 is connected at the bottom of the center seat 101 by a screw, and the upper end of the base 102 abuts against and is pressed tightly against the bottom of the leg 100, so that not only the accidental rotation of the leg 100 can be effectively prevented, but also the rotation gap between the leg 100 and the center seat 101 can be compensated, so that the standing stability of the leg 100 is better, so that the shaking of the base 1 is effectively avoided.

[0071] Further in the embodiment, the base 102 is connected with a plurality of support legs 103 along the circumference, which respectively correspond to the legs 100 and are located at the bottom of the leg 100. Specifically, as shown in the figure, Figure 10 As shown in the figure, a plurality of outwardly protruding connecting blocks 104 are arranged along the circumference of the base 102, and the connecting blocks 104 correspond one by one to the number and position of the legs 100, and the support legs 103 are connected on the connecting blocks 104 by a screw; the arrangement of the support legs 103 can prevent the legs 100 from shaking up and down due to the weight, and further improve the standing stability of the base 1.

[0072] For example, as shown in the figure, Figure 10As shown, the circumferential rotation of the central seat 101 is connected with three legs 100, and the bottom of the central seat 101 is connected with a base 102 by screws or bolts, and the periphery of the base 102 is provided with three connecting blocks 104 corresponding to the three legs 100 respectively, and each connecting block 104 is connected with a supporting leg 103 by screws, the supporting leg 103 is arranged along the length direction of the leg 100, and the top of the supporting leg 103 abuts against the bottom of the leg 100; when the base 1 stands, the three supporting legs 103 are grounded and the lower ends of the three legs 100 are grounded; the setting makes the standing stability of the base 1 high.

[0073] In some embodiments, referring again to Figure 1 、 Figure 4 and Figure 5 As shown, the shell 4 is provided with a hanging hole 400 for hanging the hanging piece. The hanging hole 400 can conveniently hang the article, thereby improving the storage capacity. Specifically, in the present embodiment, the hanging hole 400 is provided as a gourd hole with the upper part large and the lower part small, so as to conveniently and quickly hang the hanging column, thereby improving the convenience of use.
