Detailed Description
In order to make the technical solutions and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be fully described below with reference to the accompanying drawings in the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention and are not to be construed as limiting the present invention.
The following is a detailed description of an embodiment of the present invention, and fig. 1 is a schematic diagram of a human body scale according to the embodiment.
Referring to fig. 2, the body scale of the present invention comprises a main body 10, a power generating scale foot (including a moving assembly 30, a return spring 34, and a fixed pressing plate 35), a transmission assembly 50 (including a swing link 51, a tension spring 52, and a rack slider 53), a power generating assembly 20, a control panel 24, a display screen 25, and an auxiliary scale foot assembly 40 for keeping four feet on a plane.
The main body 10 comprises a scale surface 11 and a shell 12, wherein the scale surface 11 is a bearing platform with enough strength for a person to step on for measurement; the case 12 is a housing of the electronic scale, and an inner space thereof is used for mounting other components.
The moving assembly 30 comprises a moving bracket 31, a first sensor 32 and a first scale foot 33; the first sensor 32 is fixed in the moving bracket 31, the first scale foot 33 is fixed on the first sensor 32, and the moving component can move up and down relative to the main body.
A return spring 34 is installed between the moving bracket 31 and the fixed platen 35 for returning the moving assembly 30 in a non-use state.
The moving assembly 30 moves up and down within the space defined by the housing 12. As shown in fig. 3 and 4, in the reset state, the moving member 30 moves downward relative to the main body 10 under the elastic force of the return spring 34 and stops at the limit point D of the housing 12; when a person steps on the scale surface 11 of the electronic scale, the first scale foot 33 is subjected to the reaction force of the ground surface, and pushes the moving assembly 30 to move upwards relative to the main body 10 against the tension of the return spring 34 until the moving bracket 31 touches the fixed pressing plate 35 and compresses the return spring 34 in the groove space between the moving bracket 13 and the fixed pressing plate 35.
The number of the return springs 34 can be 1, or 2 or more, and the number of the return springs is 2 in the embodiment.
The fixing pressure plate 35 is fixedly connected with the main body 10 so as to facilitate assembly and maintenance, or the fixing pressure plate may not be provided and the return spring is directly connected with the main body 10.
The damping device in this embodiment is composed of a tension spring 52 and a rack slider 53.
A rotating shaft A of the swing rod 51 is connected to the main body 10, and the swing rod 51 can swing around the rotating shaft A; one end of the swing link 51 is provided with a rotating shaft B which is arranged in a connecting groove of the movable bracket 31, and the other end of the swing link 51 is provided with a hanging hole C which is connected with a draw hook of the tension spring 52. The swing rod 51 is used for driving the rotating shaft B to swing up and down through the up-and-down movement of the moving component 30 to drive the hanging hole C at the other end to swing left and right, the hanging hole C of the swing rod 51 drives the tension spring 52 to move right when swinging right, and the tension spring 52 pulls the rack slider 53 to move right along a track arranged on the main body; when the end of the swing rod C swings leftwards, the cambered surface H drives the K surface of the rack slider 53 to move leftwards. By designing the length ratio of the force arms of AC and AB (for example, AC is 10mm, AB is 4 mm), the distance of CC1 can be enlarged, the up-and-down movement distance BB1 of the moving assembly 30 in a limited space can be realized, a larger left-and-right movement distance CC1 can be obtained, namely, the gear slide block 53 obtains enough stroke to fully drive the speed-increasing gearbox 21, and the requirement of the human scale on the generated energy is met.
By arranging the speed-increasing gearbox, the stroke can be further enlarged, and the generating efficiency is higher.
The rotating shaft B of the swing rod 51 can be round or in other shapes; the hanging hole C can be a hole or a hook and can be reliably connected with the hook of the tension spring 52.
As shown in fig. 5, after a person steps on the main body 10, the moving assembly 30 moves upward relative to the main body 10, the connecting slot E of the moving bracket 31 pushes the rotating shaft B of the swing link 51 to swing upward counterclockwise, the hanging hole C at the other end of the swing link 51 pulls the tension spring 52 to move rightward, the other end of the tension spring 52 pulls the rack slider 53 to move rightward, and the rack slider 53 drives the input gear of the speed-increasing gearbox 21 to complete the driving action of power generation; after a person leaves the main body 10, under the tension of the return spring 34, the shifting assembly 30 moves downwards to be reset relative to the main body 10, the connecting groove F surface of the shifting bracket 31 pushes the swing rod 51 to swing downwards clockwise, the arc surface H at the other end C of the swing rod 51 pushes the end surface H of the rack slider 53 to move leftwards, so that the tension spring 52 and the gear slider 53 are reset, and thus, the process of driving power generation and resetting is completed once.
Two ends of the tension spring 52 are respectively provided with a hook, one end of the tension spring is connected with the hanging hole C of the swing rod 51, and the other end of the tension spring is connected with the hook of the rack sliding block 53. The tension spring 52 is used for flexibly and smoothly transmitting the arc-shaped swinging displacement of the C end of the swing link 51 to the horizontal movement of the rack slider 53. The tension spring 52 not only solves the problem that the circular arc swing of the swing rod 51 is converted into the horizontal movement of the rack sliding block 53, but also has great force when a person steps on the scale surface 11, and the speed is high, so that the moving assembly 30 can also move quickly and drive the swing rod 51 to swing quickly, through the flexible connection of the tension spring 52, the force transmitted to the rack sliding block 53 is relatively smooth, the condition of extremely acceleration cannot occur, the situation that the rack on the rack sliding block 53 is impacted with the input gear of the speed-increasing gearbox 21 to break the teeth is avoided, and the reliability is greatly improved.
The rack sliding block 53 is limited by the shell 12 to only horizontally slide in the left-right direction, the rack sliding block 53 moves rightwards and is pulled by the tension spring 52, the left movement is pushed by the C-end cambered surface of the swing rod 51, and the force comes from the tension of the return spring 34 and is flexible; the rack slider 53 drives the spring-driven leftward or rightward movement to pass through the input gear of the rack-driven speed-increasing gearbox 21, and the inside of the speed-increasing gearbox 21 is accelerated by the gear set to drive the micro-generator 22 to generate electricity, so that the purpose of generating electricity is achieved.
The control panel 24 is provided with an energy storage element 23, after the power generation assembly 20 generates power, the electric energy stored on the energy storage element 23 supplies the control panel 24 to work, the weight of the human body is calculated by measuring signals of the four sensors, and the weight is displayed on the display screen 25.
The invention mainly solves the problem that a person steps on a scale body and then converts the up-and-down displacement of the displacement assembly 30 into the left-and-right horizontal movement of the driving gear slide block 53 to drive the speed-increasing gearbox 21. As for the speed-increasing gearbox 21, the micro-generator 22, the control panel 24, the display screen 25, etc., which are well-known in the art, detailed description thereof is omitted.
Since the human body electronic scale has four scale feet, the above-mentioned moving assembly 30 is installed on only one of the scale feet. For the accuracy of the measurement, it is necessary to ensure that the heights of the four scale feet are in the same plane when the person steps on the rear scale body 11 and in the reset state after the person leaves the scale surface 11, so that when the moving assembly 30 is reset, the scale foot 33 is higher than the other 3 scale feet, resulting in the uneven balance of the scale body 10. In order to solve the problem that four scale feet are on the same plane in the measuring or resetting state, as shown in fig. 6, a device similar to the moving assembly 30 can be installed on one adjacent scale foot of one scale foot, so that two adjacent scale feet are reset, and the other two scale feet are not, so that the four scale feet are in the same plane in the resetting and measuring states, and the practice shows that the measuring result is not influenced; of course, if desired, as shown in fig. 7, it is also possible to provide four scale feet as movable scale feet, which increases the costs.
The scale foot displacement assembly with non-driving function can also adopt the scheme of the auxiliary scale foot assembly 40 besides adopting the structure similar to the displacement assembly 30. The fixed bracket 41 is fixed on the main body 10, the sensor 42 is arranged in the fixed bracket 41, the inner scale foot 43 is connected with the sensor 42, and is connected with the outer scale foot 45 through the spring 44. During measurement, the outer scale foot 45 compresses the spring 44 to complete the same distance as the displacement assembly 30, and during non-measurement the spring 45 is opened to complete the reset.
In the description herein, references to "one embodiment" or "an example" etc. mean that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above are not necessarily intended to be combined in any suitable manner in the relative embodiments or examples.
It should be noted that the above-mentioned embodiments are not intended to limit but only to help understand the core idea of the present invention, and it will be apparent to those skilled in the art that any modifications made to the present invention and alternatives equivalent to the present invention without departing from the principle of the present invention also fall within the protection scope of the appended claims.
