[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0041] As Figures 1 to 6 shown, the present invention discloses a base device. The base device includes a base. A connection area for connecting the workpiece 7 is provided on the upper surface of the base; the projection of the center of gravity of the base in the horizontal plane is located within the projection of the base in the horizontal plane; a stabilizing assembly is provided on the base. The stabilizing assembly exerts a first force on the base, and the first force causes the center of gravity of the base to move downward; a plurality of stabilizing areas are connected to the outside of the base, and the stabilizing areas and the connection area are arranged in a way of avoiding each other.

[0042] In the present invention, the projection of the center of gravity of the base in the horizontal plane is located within the projection of the base in the horizontal plane, which reduces the problem of the base tipping over due to the eccentricity of the base (the eccentricity of the base means that the center of gravity of the base is located outside the projection of the base in the horizontal plane, which will cause the base to generate a moment that is likely to tip over the base itself); at the same time, in the present invention, the first force exerted by the stabilizing assembly on the base causes the center of gravity of the base to move downward, which reduces the tipping moment generated when the base is subjected to external forces such as lateral thrust and vibration, makes the weight of the base concentrated in the lower part, closer to the support surface of the base, and further reduces the problem that the base is prone to roll over during movement due to too high a center of gravity, making the base have stronger stability; furthermore, a plurality of stabilizing areas are connected to the outside of the base, which further improves the stability of the base: the stabilizing areas have various setting forms: the stabilizing areas extend downward, which makes the overall weight of the stabilizing areas and the base move downward, reducing the overall center of gravity of the base and the stabilizing areas; the stabilizing areas extend upward, which increases the overall stress area of the base and the stabilizing areas and disperses the external force, making the base not easy to tip over; the stabilizing areas extend in the horizontal direction, which will increase the area of the base on the support surface, making the overall weight distribution of the base and the stabilizing areas more uniform, and then further improving the stability of the base; in short, through the above means, the present invention effectively improves the stability of the base, making the base not easy to topple both when it is stationary and running.

[0043] Among them, the shape of the base is not limited. It can be a cylindrical structure, a frustum structure, etc. The specific shape depends on the working conditions. According to the different connection methods between the base and the workpiece 7, the connection area can specifically be a threaded hole, or a welding area to be welded with the workpiece 7, or a clamping groove for clamping with the workpiece 7, or a pin hole for pin connection with the workpiece 7 through a pin. Correspondingly, the type of the workpiece 7 is not limited. The workpiece 7 can be a medical instrument or a beauty instrument for medical use, etc., or a structure such as steel that needs to be transported through the base. At the same time, the workpiece 7 can have various different shapes, as long as the workpiece 7 does not fall off from the connection area when moving through the base. And it should be noted that the weight of the workpiece 7 and the strength of the base need to match to ensure that the base can stably support and transport the workpiece 7.

[0044] The stabilizing assembly includes a first counterweight disposed at the lower part of the base. By arranging the first counterweight at the lower part of the base, the overall center of gravity of the base and the first counterweight is lowered, improving the overall stability of the base and the first counterweight block. Or, the stabilizing assembly includes a plurality of counterweight grooves provided on the base, and a second counterweight is placed in the counterweight grooves. The operator can place the second counterweight according to the overall balance state of the workpiece 7 and the base after placing the workpiece 7 on the base. If the workpiece 7 and the base are tilted to one side, the second counterweight is placed on the opposite side of the tilted side of the workpiece 7. The second counterweight has various weight types to meet the balance requirements of the base device under various working conditions. If the workpiece 7 and the base have a good balance state, the second counterweight may not be placed, or the second counterweight is placed at the lower part of the base. At this time, it should be noted that the placed second counterweights need to be evenly distributed around the overall center of gravity of the base and the workpiece 7 to maintain the balance state of the workpiece 7 and the base. The first counterweight, the second counterweight and the base can be in a sliding fit, a rolling fit or other fit methods. No matter which fit method, it is necessary to make the first counterweight and the second counterweight be able to be placed in the base and taken out from the base to realize flexible adjustment of the balance of the base device. The first counterweight and the second counterweight can specifically be counterweight blocks, and the counterweight blocks need to have a certain weight, but it should be noted that the weight should not be too large to prevent damage to the base.

[0045] As can be seen from the above, there are various setting methods for the stabilizing area in the present invention: the stabilizing area is arranged horizontally away from the base; or, the stabilizing area is arranged vertically downward or upward; or, the stabilizing area is inclined to the base; the stabilizing area can specifically be a plate or a block, and the stabilizing area and the base are of an integrally formed structure or a split structure. When the stabilizing area and the base are of a split structure, the stabilizing area can be connected to the base by means of threaded connection or welding, etc.

[0046] Such as Figure 3 、 Figure 6As shown, four horizontally extending stable regions are provided on the outer side of the base. The four stable regions are symmetrically distributed centered on the center of gravity of the base or the overall center of gravity of the base and the workpiece 7. At this time, the cross-section of the base is in an X shape; and the X-shaped base is more beautiful than the +-shaped base.

[0047] And / or, the base includes a support bottom plate 1 and a support panel 2 that are sequentially arranged from bottom to top and connected. A wear-resistant coating is provided on the support panel 2. The wear-resistant coating can specifically be made of materials with wear-resistant properties such as polytetrafluoroethylene. A smooth transition region is provided at the turning point of the support panel 2 (the turning point refers to the place where the contour direction of the support panel changes); and / or, several casters 5 are provided below the base.

[0048] The center of gravity of the base and the geometric center of the base are independently arranged. The center of gravity of the base and the center of gravity of the workpiece 7 are respectively located on opposite sides of the geometric center of the base; when an external force acts on the workpiece 7 provided on the base, causing a tendency for the workpiece 7 and the base to tip over, a tipping-resistant moment will be generated between the support points of the base gravity relative to the tipping of the workpiece 7, preventing the workpiece 7 and the base from tipping over, thereby ensuring the overall stability of the base and the workpiece 7.

[0049] Or, the plumb line of the base coincides with the plumb line of the workpiece 7; this reduces the problem of the base being subjected to additional torsional or bending stresses due to the offset of the overall center of gravity of the base and the workpiece 7, resulting in local damage or stress concentration points. The plumb line refers to the line connecting the center of gravity of an object to the center of the earth, and the direction of the plumb line is vertically downward.

[0050] A connecting seat 3 for connecting with the workpiece 7 is provided in the connecting region. The connecting seat 3 is cylindrical, and the axis of the connecting seat 3 coincides with the plumb line of the base. The connecting seat 3 and the workpiece 7 are coaxially arranged. The effect of coaxial arrangement has been described above and will not be repeated here. As Figure 3 shown, a number of fixing holes 4 are evenly provided in the circumferential direction of the connecting seat 3. The base and the workpiece 7 are connected through the fixing holes 4; the fixing holes 4 can specifically be bolt holes.

[0051] The lower part of the base weighs more than the upper part of the base, which moves the center of gravity of the base downward, making the tipping moment generated when the base is subjected to an external force smaller and more stable; a vibration damping member is provided on the base. The vibration damping member can specifically be a vibration damping pad provided on the base. The vibration damping pad can specifically be made of materials with vibration damping effects such as polyurethane. Or, the vibration damping member can also include a buffer cavity, a spring, and a support. The support is located below the base, and the support is slidably connected to the base in the vertical direction. The buffer cavity is arranged along the vertical and / or inclined direction of the support, and a spring is provided in the buffer cavity. The two ends of the spring are respectively abutted against or connected to the support and the base. In this way, when the base vibrates in the vertical direction or the inclined direction under the action of an external force, part of the vibration energy is converted into the deformation of the spring, thereby reducing the duration of the base vibration and improving the stability of the base.

[0052] The base is provided with an adsorption component, which includes a first adsorption component provided on the upper surface of the base, through which the workpiece 7 is adsorbed, and the auxiliary connection area improves the integrity between the base and the workpiece 7; and / or, the adsorption component includes a second adsorption component provided on the lower surface of the base, and the second adsorption component can be specifically provided on the support leg at the bottom of the base, and the stability of the base is enhanced by the second adsorption component, so that the base and the workpiece 7 are less likely to be displaced when stationary; the first adsorption component and the second adsorption component can specifically be suction cups, and the suction cups can be selected from the suction cup hooks, or, a corresponding negative pressure component can also be provided, and the air is sucked by the negative pressure component to achieve adsorption between the first adsorption component and the workpiece 7, and between the second adsorption component and the supporting surface. The base is provided with a plurality of reinforcement members, which can specifically be reinforcement ribs, or triangular support frames, and the strength of the base is improved by the reinforcement members, so that the base is less likely to be deformed and damaged during the process of carrying or transporting the workpiece 7.

[0053] Several support components are connected to the bottom of the base. The support components can move in the direction of approaching, thereby achieving abutment between the support components and the support surface, improving the stability of the base device, and the support components can also move in the direction away from the ground, thereby releasing the abutment between the support components and the support surface, making it easier for the operator to push the base device and the workpiece 7.

[0054] The support assembly in the present invention has a variety of settings. For example, the support assembly includes a first support leg threadedly connected to the base, and the first support leg can move in the vertical direction. In this case, the first support leg can be directly threadedly connected to the base, for example, an external thread is set on the first support leg, a groove is provided in the base, and an internal thread that can mesh with the external thread is set in the groove, or the first support leg includes a first support rod and a second support rod, the first end of the first support rod is connected to the base, the first end of the second support rod is slidably connected in the first support rod in the vertical direction, and a plurality of radially extending grooves are provided on the sides of the first support rod and the second support rod. The threaded hole, when the position of the second support rod is determined, the screw rod is passed through the threaded holes of the first support rod and the second support rod in sequence to fix the position of the first support rod and the second support rod, so that the second support rod cannot move relative to the first support rod. The second end of the second support rod is provided with a support for supporting the ground (the support can be understood as a support plate). When it is necessary to release or realize the contact between the second support rod and the ground, the screw rod is screwed out. At this time, the screw rod releases the fixation of the position of the first support rod and the second support rod, and the second support rod can move in the vertical direction in the first support rod, thereby realizing the adjustment of the position of the second support rod. Alternatively, the support assembly includes a second support leg provided on the base, and a driving member connected to the second support leg in a transmission manner, the driving member is used to drive the second support leg to move in the vertical direction, and the driving member can be a driving device such as a cylinder or a hydraulic cylinder or an electric push rod that can drive the second support leg to perform linear motion.

[0055] Alternatively, the support component may not adopt the above structure. For example, the support component includes a support plate provided on the base. The support plate is rotatably connected to the base in a vertical plane (the rotation connection point of the support plate and the base can be the midpoint of the support rod). The support plate can rotate in the vertical plane. A third support leg is connected to the first end of the support plate. The third support leg is arranged in the vertical direction. The rotation trajectory of the third support leg intersects the support surface of the base. A first chute is provided on the support plate. A third counterweight and a reset member are sequentially arranged in the first direction in the first chute. The third counterweight is slidably connected to the first chute in the first direction. The reset member exerts a first acting force on the third counterweight. The first acting force is arranged in the first direction. The first direction is set from the second end of the support plate towards the first end of the support plate. The electromagnet is located on the side of the second end of the support plate away from the first end of the support plate. The electromagnet is arranged to avoid the first reset member. The electromagnet exerts a second acting force on the third counterweight. The second acting force is greater than the first acting force. The direction of the second acting force is opposite to the direction of the first acting force. The first chute is long enough so that the third counterweight can move to a position close to the first end of the support plate, so that the third support leg abuts against the support surface under the action of the third counterweight. It is also necessary to enable the third counterweight to move to a position close to the second end of the support plate, so that the third support leg disengages from the support surface under the action of the third counterweight. The arrangement to avoid the electromagnet and the reset member means that the functions of the electromagnet and the reset member do not interfere with each other. The base is equipped with a power supply connected to the electromagnet to supply power to the electromagnet, and a switch connected to the power supply to control the on / off of the power supply. The two ends of the reset member can be respectively connected to the third counterweight and the second end of the support plate. Alternatively, a limiting plate is provided on the first chute to prevent the reset member from popping out. The reset member can specifically be a structure such as a spring that can exert a first acting force on the third counterweight. The third counterweight can specifically be a counterweight block or the like with sufficient weight to realize the rotation of the support plate.

[0056] When it is necessary to move the base and the workpiece 7, the switch is activated, the electromagnet is powered on, and the electromagnet exerts a second acting force on the third counterweight. Since the second acting force is greater than the first acting force, the third counterweight can move in the direction of the second end of the support plate under the action of the second acting force. At this time, since the third counterweight is closer to the second end of the support plate, the gravity in the area of the second end of the support plate is greater than the gravity in the area close to the first end of the support plate. This causes the first end of the support plate and the third support leg to rotate away from the support surface, so that the third support leg releases the abutment with the support surface. When the base and the workpiece 7 do not need to be moved, since the electromagnet is not powered on, the second acting force disappears, and the first acting force causes the third counterweight to move in the direction of the first end of the support plate. At this time, since the third counterweight is closer to the first end of the support plate, the gravity in the area close to the first end of the support plate is greater than the gravity in the area close to the second end of the support plate. The first end of the support plate will rotate towards the support surface, so that the third support leg abuts against the support surface, improving the stability of the base device and the workpiece 7.

[0057] In addition, the support assembly may not adopt the structure described in the above paragraph. In this case, the support assembly includes a second slide groove and a third slide groove which are arranged on the base and are connected. The third slide groove is opened in the horizontal direction, and the second slide groove is opened in the vertical direction. The second slide groove is slidably connected to the fourth leg in the vertical direction. The length of the second slide groove is not less than the length of the fourth leg. The first end of the fourth leg is provided with a limit rod, and the limit rod can be extended into the third slide groove. The second end of the fourth leg can be against the support surface of the base. The third slide groove includes a first groove group located at the upper part and a second groove group located at the lower part. The first groove group includes a plurality of first grooves arranged at intervals in the horizontal direction, and the second groove group includes a plurality of second grooves arranged at intervals in the horizontal direction. The first groove and the second groove are arranged alternately. In this way, when the limit rod needs to be transferred into the third slide groove, the limit rod can be stuck in the first groove or the second groove. Under the action of the baffle between two adjacent first grooves or the baffle between two adjacent second grooves, the limit rod will not accidentally leave the third slide groove.

[0058] When the base and the workpiece 7 need to be moved, the fourth leg is lifted until the limit rod is aligned with the second slide groove, and the limit rod is rotated toward the third slide groove so that the limit rod is stuck in the third slide groove, thereby achieving the separation of the fourth leg from the supporting surface; when the base and the workpiece 7 do not need to be moved, the limit rod is rotated out of the third slide groove, and the fourth leg is moved down so that the fourth leg is against the supporting surface.

[0059] The base is provided with a plurality of movable parts connected to the base, the top of the movable parts is not lower than the bottom surface of the base, the bottom of the movable parts is lower than the bottom surface of the base, and the movable parts can move on the ground; the movable parts can specifically be casters 5 or tracks; by raising the height of the top of the movable parts, the movable parts are no longer located below the bottom surface of the base, which reduces the height of the base, moves the center of gravity of the base downward, and improves the stability of the base.

[0060] The base is provided with an angular velocity sensor, an alarm and a controller, and the angular velocity sensor and the alarm are connected to the controller signal; when the controller determines that the tilt angle of the base reaches a threshold value based on the feedback of the angular velocity sensor, the alarm is activated to remind the operator to adjust the base, such as adding or removing the first or second counterweight block, retracting or releasing the support assembly, and then avoiding the base device and the workpiece 7 from directly tipping over. The alarm can be specifically an audible and visual alarm. The angular velocity sensor can be specifically a gyroscope.

[0061] A first protective plate is provided on the side of the base. The length of the first protective plate in the vertical direction is not less than the height of the workpiece 7. A buffer pad is provided on the side of the first protective plate facing the workpiece 7. This ensures that even if the base device and the workpiece 7 tip over, it is the first protective plate that contacts the support surface of the base, avoiding the contact between the workpiece 7 and the support surface and reducing the damage to the workpiece 7; and / or, a receiving groove is provided on the side of the base and opened in the vertical direction, and an airbag is provided in the receiving groove; when the outer side of the receiving groove abuts against the support surface of the base, the airbag pops out of the receiving groove, thus avoiding the direct contact between the workpiece 7 and the support surface and reducing the damage to the workpiece 7; the principle of the airbag popping out of the receiving groove can refer to the principle of the airbag popping out in an automobile.

[0062] The support surface of the base refers to the surface that bears the base. According to the working conditions, the support surface can be the ground or the floor, etc.

[0063] In the present invention, the base can be used to support the main body and facilitate the handling of the main body (the main body can be understood as the main body of a beauty instrument or a medical device). Since the overall weight of the main body is relatively heavy, a plurality of casters 5 are provided on the base, and a brake 6 is further provided on the caster 5. The brake 6 is a prior art, and its specific structure will not be described in detail for the convenience of moving the main body. In the present invention, the support bottom plate 1 and the support panel 2 have no sharp corners in the outer contour, and are both designed with arcs or rounded corners to avoid possible injuries to personnel caused by the base. The support panel 2 covers the support bottom plate 1 and covers the edge corners of the support bottom plate 1. The support panel 2 has rounded corners. The shapes of the support panel 2 and the support bottom plate 1 match so that the support panel 2 can be buckled on the support bottom plate 1. On the one hand, the support panel 2 is used for decoration to beautify the connection between the support bottom plate 1 and the connection area (the connection area is provided on the support bottom plate 1, and the support panel 2 passes through the connection area and is buckled on the support bottom plate 1). On the other hand, the support panel 2 contacts the main body of the host. The ends of the support panel 2 and the main body of the host are both arc-shaped, which increases the contact area between the support panel 2 and the main body of the host and plays a certain protective role. When the workpiece is the main body, a display screen 9, a handpiece system 10 (the handpiece system 10 can be understood as a beauty handle) and an armrest 8 are provided on the main body.
