Description

Technical Field

[0001] The present application relates to the technical field of electronic product support devices, and in particular to an electronic product support device with switchable restoring force. Background Art

[0002] Restoration refers to the ability of a device to return to its original state after being acted upon by an external force. Currently, there are a variety of electronic product support devices on the market, such as height-adjustable computer stands, mobile phone stands, etc. These devices generally have the function of supporting and fixing electronic products.

[0003] In terms of restoring force control, existing technologies mainly rely on the design of mechanical structures and the selection of materials. For example, some devices use mechanical elements such as springs or dampers to provide restoring force, and the restoring force is changed by adjusting the stiffness of the spring or the damping coefficient of the damper. In addition, some devices use smart materials such as memory alloys to adjust their shape and restoring force by changing the temperature or electric field of the material. In addition, with the development of intelligent technology, some electronic product support devices have also begun to introduce sensors and control systems, which automatically adjust the restoring force to meet user needs by real-time monitoring of the device status and external environment.

[0004] Although the prior art has made some progress in the control of the restoring force of electronic product support devices, there are still some problems:

[0005] 1. Some devices require users to manually operate complex adjustment devices when adjusting the restoring force, such as replacing springs or adjusting dampers. This operation method is not only cumbersome, but also may require certain professional knowledge and skills, which is not conducive to the use of ordinary users.

[0006] 2. Since some devices need to use equipment such as sensors or control systems when adjusting the restoring force, the overall cost is high and they occupy a certain space, making them unsuitable for large-scale promotion.

[0007] 3. Some devices with complex mechanical structures or smart materials may experience reduced stability or insufficient durability during long-term use. This not only affects the service life of the device, but may also have a negative impact on the user experience. Utility Model Content

[0008] The purpose of the present application is to provide an electronic product support device with switchable restoring force to solve at least one technical problem existing in the prior art.

[0009] In order to solve the above technical problems, the present application provides an electronic product support device with switchable restoring force, comprising a bracket, a lifting part, an elastic part, a first rope, a second rope, an outer pulley, an inner pulley and a switching part;

[0010] The lifting part is escalably arranged on the bracket and connected to the first rope;

[0011] The upper end of the first rope is fixedly arranged on the lifting part, and the lower end is wound around the outer pulley;

[0012] The upper end of the second rope is connected to the elastic part, and the lower end is wound around the inner pulley;

[0013] The outer pulley is coaxially arranged with the inner pulley, and the two are relatively fixed in the circumferential direction;

[0014] The switching portion is arranged on a side of the outer pulley away from the inner pulley, and can be used to adjust the diameter of the outer pulley.

[0015] Furthermore, a plurality of first grooves are provided on the inner pulley;

[0016] The first groove body is a long strip groove body arranged along the radial direction of the inner pulley;

[0017] The outer pulley is composed of a plurality of sliders, and each slider is provided with a first protrusion on a side close to the inner pulley;

[0018] The first protrusion is a long strip protrusion arranged along the radial direction of the outer pulley, and its length is less than the length of the first groove body;

[0019] The first protrusion can cooperate with the first groove body, so that the outer pulley and the inner pulley are fixed in the circumferential direction, and the slider can move along the direction of the first groove body, so that the diameter of the outer pulley can guide and limit the slider when it increases or decreases.

[0020] Furthermore, a plurality of second slots are provided on a side of the switching portion close to the outer pulley;

[0021] The shape of the second groove body is a part of an Archimedean spiral;

[0022] Each of the sliders is provided with a second protrusion on a side close to the switching portion;

[0023] The second protrusion is columnar and can be matched with the second groove body;

[0024] The switching portion is rotated to make the second protrusion move along the track of Archimedean spiral in the second groove body, so that the plurality of sliders are moved closer or farther away from each other, thereby realizing the switching of the diameter of the outer pulley.

[0025] Preferably, the number of the first slot bodies, the number of the second slot bodies and the number of the sliders are all four.

[0026] Furthermore, the elastic part is a 5kg constant force spring, which is fixed to the bracket through a fixing part.

[0027] Furthermore, the switching portion is disc-shaped and is coaxially arranged with the outer pulley.

[0028] Furthermore, a handle is provided on a side of the switching portion away from the outer pulley.

[0029] Furthermore, the diameter of the inner pulley is 56 mm, and the diameter of the outer pulley switches between 70 mm and 56 mm, which are used to adapt to 24-inch and 27-inch displays respectively.

[0030] Furthermore, a guide wheel is provided on the lifting part, and the first rope is guided by the guide wheel and then extends downward to be wound and connected with the outer pulley.

[0031] Furthermore, the bracket is provided with a guide rail, and the lifting part is lifted and lowered by the guide rail.

[0032] By adopting the above technical solution, the present application has the following beneficial effects:

[0033] First, the device introduces a switchable outer pulley diameter design. Through the operation of the switch, the outer pulley diameter can be easily adjusted to meet the support requirements of monitors of different sizes. This design not only improves the flexibility and versatility of the device, but also simplifies the adaptation process of different monitor sizes, making the device more convenient to use.

[0034] Secondly, the combination of the lifting part, the elastic part, the rope and the pulley in the device realizes stable support and lifting adjustment of the monitor. The lifting movement of the lifting part on the bracket, combined with the connection between the first rope and the outer pulley, allows the height of the monitor to be flexibly adjusted. The introduction of the elastic part provides a constant restoring force to ensure the stability and safety of the monitor during the lifting process.

[0035] In addition, the switching part, the inner pulley and the outer pulley in the device are exquisitely designed. Through the cooperation of the first groove body and the first protrusion, the outer pulley and the inner pulley are fixed in the circumferential direction, and can play a guiding and limiting role in the diameter change of the outer pulley when the slider moves along the direction of the first groove body. The diameter of the outer pulley is controlled by the cooperation of the second protrusion and the second groove body. This design not only ensures the stability and reliability of the pulley system due to its simple and exquisite design, but also reduces the difficulty of use and manufacturing cost of the device.

[0036] Finally, the device is also equipped with humanized designs such as handles to make operation easier. At the same time, the optimal design of key components such as the elastic part and the switching part further improves the adaptability of the device.

[0037] In summary, the electronic product support device with switchable restoring force achieves flexible support and height adjustment for displays of different sizes through ingenious structural design and functional optimization, which improves the convenience and reliability of use while reducing the operating difficulty and manufacturing cost, and has significant beneficial effects.

[0049] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] The present application is further explained below in conjunction with specific implementation methods.

[0051] like Figure 1-6 As shown, the present embodiment provides a restoring force switchable electronic product support device, comprising a bracket 1, a lifting part 2, an elastic part 3, a first rope 4, a second rope 5, an outer pulley 6, an inner pulley 7 and a switching part 8;

[0052] The lifting part 2 is escalably disposed on the bracket 1 and is connected to the first rope 4;

[0053] The upper end of the first rope 4 is fixedly arranged on the lifting part 2, and the lower end is wound around the outer pulley 6;

[0054] The upper end of the second rope 5 is connected to the elastic part 3, and the lower end is wound around the inner pulley 7;

[0055] The outer pulley 6 and the inner pulley 7 are coaxially arranged and relatively fixed in the circumferential direction;

[0056] The switching portion 8 is disposed on a side of the outer pulley 6 away from the inner pulley 7 , and can be used to adjust the diameter of the outer pulley 6 .

[0057] When the electronic product support device with switchable restoring force of the present application is in operation, the electronic product (such as a computer monitor) is arranged on the lifting part 2. When the lifting part 2 is pressed downward, the first rope 4 pulls the outer pulley 6 to rotate, and the outer pulley 6 drives the inner pulley 7 to rotate, thereby pulling the elastic part 3 through the second rope 5, thereby realizing force transmission.

[0058] As a further embodiment of the present application, a plurality of first slots 9 are provided on the inner pulley 7;

[0059] The first groove body 9 is a long strip groove body arranged along the radial direction of the inner pulley 7;

[0060] The outer pulley 6 is composed of a plurality of sliders, each of which is provided with a first protrusion 10 on a side close to the inner pulley 7;

[0061] The first protrusion 10 is a long strip protrusion arranged along the radial direction of the outer pulley 6, and its length is less than the length of the first groove body 9;

[0062] The first protrusion 10 can cooperate with the first groove body 9, so that the outer pulley 6 and the inner pulley 7 are fixed in the circumferential direction, and the slider can be moved along the direction of the first groove body 9, so that the diameter of the outer pulley 6 can guide and limit the slider when it increases or decreases.

[0063] As a further embodiment of the present application, a plurality of second slots 11 are provided on a side of the switching portion 8 close to the outer pulley 6;

[0064] The shape of the second slot body 11 is a part of an Archimedean spiral;

[0065] Each of the sliders is provided with a second protrusion 12 on one side close to the switching portion 8;

[0066] The second protrusion 12 is columnar and can be matched with the second groove body 11;

[0067] By rotating the switching portion 8 , the second protrusion 12 moves in the second groove body 11 along the track of the Archimedean spiral, so that the plurality of sliders are brought closer or farther away from each other, thereby achieving the switching of the diameter of the outer pulley 6 .

[0068] As a preferred embodiment of the present application, the number of the first slot bodies 9, the number of the second slot bodies 11 and the number of the sliders are all four.

[0069] When the electronic product support device with switchable restoring force of the present application is in operation, the switching part 8 is rotated to make the second protrusion 12 move along the second groove body 11, so that the four sliders are pushed outward or inward synchronously, and the first protrusion 10 thereon is also guided and limited to move in the first groove body 9, so as to realize the change of the diameter of the outer pulley 6, while the diameter of the inner pulley 7 is always constant.

[0070] As a further embodiment of the present application, the elastic part 3 is a 5kg constant force spring, which is fixed to the bracket 1 by a fixing part. The switching part 8 is disc-shaped and is coaxially arranged with the outer pulley 6. A handle 13 is also provided on the side of the switching part 8 away from the outer pulley 6. The diameter of the inner pulley 7 is 56mm, and the diameter of the outer pulley 6 switches between 70mm and 56mm, which are respectively used to adapt to 24-inch and 27-inch monitors. A guide wheel 14 is provided on the lifting part 2, and the first rope 4 extends downward after being guided by the guide wheel 14 and is wound and connected with the outer pulley 6. A guide rail 15 is provided on the bracket 1, and the lifting part 2 is lifted and lowered by the guide rail 15.

[0071] When the electronic product support device with switchable restoring force of the present application is working, since the product of the tension of the elastic part 3 and the diameter of the inner pulley 7 is equal to the product of the restoring force and the diameter of the outer pulley 6, when the tension of the elastic part 3 and the diameter of the inner pulley 7 are constant, the size of the restoring force can be changed by changing the diameter of the outer pulley 6.

[0072] According to the current market situation, a 24-inch computer monitor weighs about 4kg, and a 27-inch computer monitor weighs about 5kg. When the constant tension of the elastic part 3 is 5kg, the diameter of the inner pulley 7 is 56mm, and the diameter of the outer pulley 6 is 70mm, the restoring force of the lifting part 2 is 4kg, which can adapt to a 24-inch computer monitor. When the diameter of the outer pulley 6 is switched to 56mm, the restoring force of the lifting part 2 is 5kg, which can adapt to a 27-inch computer monitor.

[0073] like Figure 5-6 The figure shows a further embodiment of the present application, wherein one or more positioning deep grooves 16 are further provided in the second groove body 11, and the second protrusion 12 is matched with the positioning deep groove 16;

[0074] The switching part 8, the outer pulley 6 and the inner pulley 7 are provided with an opening at their centers, and an elastic clamping part 17 is provided in the opening;

[0075] One end of the elastic clamping portion 17 is fixedly connected to the bracket 1, and the other end is clamped on the switching portion 8;

[0076] When the diameter of the outer pulley 6 needs to be changed, the switching portion 8 is pulled outward and rotated, and when it is switched to the corresponding diameter, the switch is released, and the elastic clamping portion 17 contracts so that the second protrusion 12 fits into the positioning deep groove 16.

[0077] As a further embodiment of the present application, a diameter mark is also provided on the switching portion 8 for determining the diameter size of the outer pulley 6 in the current situation.

[0078] By adopting the above technical solution, the present application has the following beneficial effects:

[0079] First, the device introduces a switchable outer pulley diameter design. Through the operation of the switch, the outer pulley diameter can be easily adjusted to meet the support requirements of monitors of different sizes. This design not only improves the flexibility and versatility of the device, but also simplifies the adaptation process of different monitor sizes, making the device more convenient to use.

[0080] Secondly, the combination of the lifting part, the elastic part, the rope and the pulley in the device realizes stable support and lifting adjustment of the monitor. The lifting movement of the lifting part on the bracket, combined with the connection between the first rope and the outer pulley, allows the height of the monitor to be flexibly adjusted. The introduction of the elastic part provides a constant restoring force to ensure the stability and safety of the monitor during the lifting process.

[0081] In addition, the switching part, the inner pulley and the outer pulley in the device are exquisitely designed. Through the cooperation of the first groove body and the first protrusion, the outer pulley and the inner pulley are fixed in the circumferential direction, and can play a guiding and limiting role in the diameter change of the outer pulley when the slider moves along the direction of the first groove body. The diameter of the outer pulley is controlled by the cooperation of the second protrusion and the second groove body. This design not only ensures the stability and reliability of the pulley system due to its simple and exquisite design, but also reduces the difficulty of use and manufacturing cost of the device.

[0082] Finally, the device is also equipped with humanized designs such as handles to make operation easier. At the same time, the optimal design of key components such as the elastic part and the switching part further improves the adaptability of the device.

[0083] In summary, the electronic product support device with switchable restoring force achieves flexible support and height adjustment for displays of different sizes through ingenious structural design and functional optimization, which improves the convenience and reliability of use while reducing the operating difficulty and manufacturing cost, and has significant beneficial effects.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
