Description

Technical Field

[0001] This application relates to the field of support and fixing device technology, and more specifically, to a support device and a lighting assembly. Background Technology

[0002] Currently available screen light holders on the market are fixed to the monitor. Most of these holders work by using a front baffle that clips onto the top edge of the monitor, and a counterweight and torsion spring at the rear to provide clamping force, securing the holder to the top of the monitor. This solution has several problems and user pain points, such as: Insufficient torsion spring torque prevents the lamp holder from being stably fixed to the monitor. Especially when pressing the lamp holder, if the torque is too low, it easily slips off the monitor; if the torsion spring torque is too high, the lamp holder easily slips off the monitor upwards. Furthermore, the thicker the monitor being held, the greater the torsion spring torque needs to be, increasing the risk of the lamp holder slipping off. Therefore, both excessive and insufficient torsion spring torque have drawbacks, causing lamp holder instability.

[0003] Furthermore, the lamp holder's counterweight is usually placed in the second support section. While theoretically, as the monitor's thickness increases, the second support section can open at a wider angle, shifting the lamp holder's center of gravity backward and improving stability, the counterweight's placement in the second support means the torsion spring must first overcome the counterweight's weight before providing the necessary clamping force. Moreover, to meet the requirements of ultra-thin monitors, the torsion spring must initially overcome the counterweight's weight (at which point the counterweight's lever arm is at its maximum, requiring a large torque). As the monitor's thickness increases, the torsion spring's force gradually increases, and the counterweight's center of gravity gradually shifts backward and closer to the second support section's rotation center. In other words, as the monitor's thickness increases, the torque increases, while the force required to overcome the counterweight gradually decreases. This inevitably increases the risk of the lamp holder slipping upward from the monitor. Furthermore, as the monitor's thickness increases, the torsion spring force increases, increasing the clamping force of the lamp holder on the monitor, thus raising the risk of damage.

[0004] To address the aforementioned problems, this application provides a support device for supporting an external device and fixing it to a target object. The support device includes: The first support part is used to support the upper part of the target object. One end of the first support part is provided with a mounting end for attaching external equipment, and the other end is provided with a rotating end. A baffle protrudes from the bottom side of the first support and is used to abut against the front edge of the target object. The second support part has a connecting end at one end and a free end at the other end. The connecting end is connected to the rotating end through a constant force rotating assembly, and the free end is used to abut against the rear surface of the target object. The counterweight is disposed in the first support part and is configured such that when the first support part supports the upper end of the target object, the baffle can abut against the front edge of the target object and the free end of the second support part can abut against the rear surface of the target object, so that the first support part, the second support part and the target object form a triangular structure and the second support part and the first support part can form an acute angle.

[0005] In the above technical solution, the first support part has a neck and a beam on both sides of the plane where the baffle is located, the hook end is located at the end of the neck away from the beam, and the rotating end is located at the end of the beam away from the neck. The neck extends less than the beam, and the counterweight is located on the beam.

[0006] In the above technical solution, a receiving cavity is formed inside the beam, and the counterweight is installed inside the receiving cavity.

[0007] In the above technical solution, the counterweight is configured such that, relative to the attachment end and the rotating end of the first support, the center of gravity of the counterweight is close to the rotating end of the first support.

[0008] In the above technical solution, the neck extends upward at an angle from the side near the baffle to the side away from the baffle, and its extended end forms a hook end; The beam extends horizontally from the side closest to the baffle to the side furthest from the baffle, and its extended end forms a rotating end.

[0009] In the above technical solution, the thickness of the first support part is greater than the thickness of the second support part.

[0010] In the above technical solution, the first support part includes an upper support cover and a lower support cover, and the upper support cover and the lower support cover are connected and fitted together to form a receiving cavity that can accommodate the counterweight.

[0011] In the above technical solution, the bottom side of the first support part is provided with an anti-slip component; and / or The baffle is equipped with anti-slip components; and / or The free end of the second support is equipped with an anti-slip component; The anti-slip component is used to increase contact friction when the first support and / or baffle and / or second support comes into contact with the target object.

[0012] In the above technical solution, a concave notch is formed at the middle of the free end of the second support, and protrusions for abutting against the rear surface of the target object are formed on both sides of the notch.

[0013] In the above technical solution, the constant force rotation component is at least one of the following: a torque shaft, a mechanical positioning shaft, or a bendable plate.

[0014] In the above technical solutions, the constant force rotation component adopts either the first or the second design method: In the first design approach, the constant force rotation assembly includes: The shaft core is fixed to the rotating end of the first support part; The rotating bracket has two sets, which are rotatably mounted at both ends of the shaft core. At least one of the two sets of rotating brackets is fixed to the connecting end of the second support part so that the second support part can rotate relative to the first support part. The friction plate is sleeved on the outer circumference of the shaft core and is in frictional engagement with at least one of the two rotating supports. In the second design approach, the constant force rotation component includes: The shaft core is fixed to the rotating end of the first support part; A bushing is pressed onto the outer circumference of a shaft core to generate torque when the bushing rotates relative to the shaft core. The outer circumference of the bushing is configured as a regular polygonal structure or an irregular structure. The connecting end of the second support is provided with a mounting hole that is adapted to the outer peripheral structure of the bushing. The bushing is located in the mounting hole and can be limited by the mounting hole in the circumferential direction.

[0015] This application also provides a lighting assembly, which includes a lamp body and a support device provided in this application embodiment, wherein the lamp body is rotatably connected to the mounting end.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: This application provides a support device and a lamp assembly. A counterweight in the support device is disposed in a first support portion to maintain the balance between the external device and the support device. A constant-force rotation component is disposed between the first and second support portions, ensuring the second support portion is in close contact with the rear surface of the target object. Thus, the rear surface of the target object, the first support portion, and the second support portion form a stable triangular support structure, specifically an acute-angle structure with higher stability. Therefore, in this embodiment, the relative positions of the center of gravity of the support device and the center of gravity of the external device remain constant, and since the rotation component is a constant-force rotation component, the force exerted by the second support portion on the target object remains constant. That is, in this embodiment, there is no change in the rotation force and lamp holder stability (whether it increases or decreases) due to changes in the thickness of the target object; the first and second support portions form an acute angle, and a stable triangular structure is maintained between the first and second support portions and the target object.

[0025] Example 1 like Figures 1-7 As shown, in the first aspect of embodiment 1 of this application, a support device is provided for supporting an external device to be fixed on a target object. The support device includes: The first support part 10 is used to support the upper end of the target object. One end of the first support part is provided with a hanging end 101 for hanging external equipment, and the other end is provided with a rotating end 102. A baffle 30 protrudes from the bottom side of the first support part 10 and is used to abut against the front edge of the target object. The second support part 20 has a connecting end 201 at one end and a free end 202 at the other end. The connecting end 201 is connected to the rotating end 102 through the constant force rotating assembly 40, and the free end 202 is used to abut against the rear surface of the target object. The counterweight 50 is disposed on the first support part 10. The counterweight 50 is configured such that when the first support part 10 supports the upper end of the target object, the baffle 30 can abut against the front edge of the target object and the free end 202 of the second support part 20 can abut against the rear surface of the target object, so that the first support part 10, the second support part 20 and the target object form a triangular structure, and the second support part 20 and the first support part 10 can form an acute angle.

[0026] As can be seen, the support device in this embodiment mainly consists of two parts: a first support part 10 and a second support part 20. The target object includes, but is not limited to, a monitor, a television, etc., and the external device includes, but is not limited to, a lamp body, a camera, etc. Taking the lamp body as the external device and the monitor as the target object as an example, the support device can be understood as a lamp holder. A rotating shaft or magnetic structure can be used to connect the first support part 10 to the lamp body; rotating the lamp body adjusts the illumination angle. A counterweight 50 is provided inside the first support part 10 to balance the weight of the lamp body {the center of gravity of the support device remains relatively constant with respect to the lamp body, ensuring reliable stability}. A constant force rotation component 40 is provided between the first support part 10 and the second support part 20. The constant force rotation component 40 can adjust the angle between the second support part 20 and the first support part 10, thereby adjusting the distance between the free end 202 of the second support part 20 and the baffle 30, adapting to displays of different thicknesses. Furthermore, the constant force rotation component 40 provides a stable supporting force, regardless of the angle between the second support part 20 and the first support part 10, thus ensuring that the force exerted by the second support part 20 on the display remains constant. Therefore, in the support device of this application, the first support part 10, the second support part 20, and the display can form a stable triangular support structure. Figures 5-7 As shown, the triangular support structure can also maintain a more stable acute angle structure, thus enabling the external device to be stably supported on the target object.

[0027] Specifically, the first support part 10 is equipped with a counterweight 50. Taking the support device hanging the lamp body as an example, when the lamp body is hung at the hanging end 101 of the first support part 10 of the support device, the counterweight 50 can maintain the balance between the center of gravity of the support device and the center of gravity of the lamp body. At the same time, since a constant force rotation component 40 is set between the first support part 10 and the second support part 20, the support device no longer clamps the display, so that the support device has no clamping force on the display. This not only solves the problem of damage to the display caused by the clamping force of the support device, but also solves the risk of the lamp body slipping upward on the display due to the clamping force of the torsion spring. Furthermore, by adjusting the rotation angle of the second support part 20 relative to the first support part 10, the support device can also be adapted to displays of different thicknesses.

[0028] like Figure 7 As shown, when the support device in this embodiment is equipped with a lamp body, its stability principle is as follows: The ratio B = ≤1; G1: Lamp body weight; L1: Lamp weight center lever arm; G2: Weight of the support device; L2: The center of gravity lever arm of the support device; The smaller the value of ratio B, the more stable the lamp body is: If the ratio B remains constant, the longer the center of gravity arm L2 of the support device, the smaller the weight of the counterweight can be, and the lower the cost.

[0029] If G2 remains constant, the larger L2 is, the smaller the ratio B is, and the more stable the support device will be.

[0030] like Figure 6 As shown, when angle A < 90 degrees, the stability of the support device is well maintained. That is, the prerequisite for the stability of the support device on the display is that the first support part 10, the second support part 20 and the display (i.e. the target object) form a stable triangular structure, wherein the first support part 10 and the second support part 20 form an acute angle.

[0031] It should be noted that the constant force rotation component 40, instead of a torsion spring structure, is provided between the first support portion 10 and the second support portion 20 in this embodiment. This is because the torque generated by the torsion spring would cause the baffle 30 to exert a continuous clamping force on the front end of the display and the second support portion 20 on the back end of the display. Moreover, the thicker the display, the greater the clamping force, which could cause significant damage to the display. In this embodiment, the constant force rotation component 40 ensures that when the second support portion 20 is rotated relative to the first support portion 10 by an external force, and the constant force rotation component 40 maintains its current rotation angle when the external force is removed. The constant force rotation component 40 prevents the support device from exerting a clamping force on the back panel and the front bezel of the display. The entire support device overlaps and supports the display, and the only force exerted on the display is caused by the weight of the support device. Therefore, when the support device provided in this embodiment is equipped with a lamp and hung on the display, the degree of damage to the display can be reduced by more than 90%.

[0032] It should also be noted that the effect of the constant force rotation component 40 mentioned above is as follows: on the one hand, when an external force is applied, the rotation angle of the second support part 20 relative to the first support part 10 can be adjusted, and when there is no external force, the current angle of the second support part 20 can be maintained; on the other hand, no matter what the rotation angle of the second support part 20 relative to the first support part 10 is, the force exerted by the second support part 20 on the target object remains basically unchanged.

[0033] It should also be noted that the "triangular structure" mentioned in the embodiments of this application does not need to be a triangle in the geometric sense. As long as it is generally distributed in a "triangular shape", it can satisfy the visual and mechanical framework of "general triangle" without the need for the three points to be coplanar, the sides to be straight, or the angles to be precise.

[0034] Furthermore, in some possible embodiments, the first support portion 10 has a neck and a beam portion formed on both sides of the plane where the baffle 30 is located, the hook end 101 is located at the end of the neck away from the beam portion, and the rotating end 102 is located at the end of the beam portion away from the neck. The extension length of the neck is less than the extension length of the beam, and the counterweight 50 is mounted on the beam.

[0035] In this embodiment, the counterweight 50 is placed on the beam with a longer extension length. Therefore, the center of gravity lever arm L2 generated by the support device is longer, which naturally reduces the ratio B = (G1·L1) / (G2·L2). Thus, it is possible to satisfy B≤1 without adding extra weight to the counterweight 50, achieving the effect of "small counterweight - high stability". That is, in this embodiment, the counterweight is concentrated on the beam with a longer lever arm, which can obtain the same anti-overturning moment with a smaller counterweight.

[0036] It should be noted that, preferably, the "extension length of the beam" mentioned above refers to the extension length along the plane perpendicular to the baffle 30.

[0037] Furthermore, in some possible embodiments, a receiving cavity is formed inside the beam, and the counterweight 50 is installed in the receiving cavity.

[0038] In this embodiment, the counterweight 50 is concealed within a closed cavity, with no exposed surface, thus meeting the aesthetic requirement of "no visible metal counterweight" in consumer electronics; at the same time, it makes full use of the internal space of the first support part 10.

[0039] Furthermore, in some possible embodiments, the counterweight 50 is configured such that its center of gravity is close to the rotating end 102 of the first support 10 relative to the hook end 101 and the rotating end 102 of the first support 10.

[0040] In this embodiment, the distance between the center of gravity of the counterweight 50 and the rotating end 102 is much smaller than the distance between it and the hanging end 101. This causes the center of gravity of the support device to move closer to the rotation center of the constant force rotating component 40, thereby making the lever arm L2 longer. According to the stability principle formula mentioned above, the ratio B = (G1·L1) / (G2·L2) is further reduced. Under the premise of keeping B≤1, the required weight of the counterweight 50 is reduced, achieving the effect of "light counterweight - high stability".

[0041] Furthermore, in some possible embodiments, the neck extends obliquely upward from the side near the baffle 30 to the side away from the baffle 30, and its extended end is formed with a hook end 101. The beam extends horizontally from the side near the baffle 30 to the side away from the baffle 30, and a rotating end 102 is formed at the end of its extension.

[0042] In this embodiment, the neck is tilted upwards, so that after the lamp body is installed, the illumination center of the lamp body naturally tilts downwards, which conforms to the optimal reading angle for the human eye and reduces the need for secondary adjustments by the user. The beam extends horizontally backwards, and the interior of the beam provides space for counterweights, electronic modules, etc., further improving the stability of the support device when it is attached to the target object.

[0043] Furthermore, in some possible implementations, the thickness of the first support portion 10 is greater than the thickness of the second support portion 20.

[0044] In this embodiment, the first support portion 10, due to the installation of the counterweight 50, has a thicker volume design that can accommodate a larger counterweight 50 inside. The second support portion 20, on the other hand, only has its end abutting against the target object, so it does not need to be designed with a thicker thickness. Its thinner design allows the second support portion 20 and the first support portion 10 to be folded together, resulting in a smaller overall size that is easier to carry.

[0045] Furthermore, in some possible implementations, such as Figure 2 As shown, the first support part 10 includes a support upper cover 10a and a support lower cover 10b, which are mated together to form a receiving cavity capable of accommodating the counterweight 50.

[0046] In this embodiment, the upper support cover 10a and the lower support cover 10b interlock to form a closed cavity, so that components such as the counterweight 50 and the main control board can be installed at once, resulting in high assembly efficiency.

[0047] Furthermore, in some possible implementations, such as Figure 2 As shown, The bottom side of the first support part 10 is provided with an anti-slip component 60; and / or The baffle 30 is equipped with an anti-slip component 60; and / or The free end 202 of the second support part 20 is provided with an anti-slip component 60; The anti-slip component 60 is used to increase contact friction when the first support 10 and / or the baffle 30 and / or the second support 20 come into contact with the target object.

[0048] Preferably, the anti-slip component 60 is made of soft rubber. That is, the soft rubber on the first support part 10, the baffle 30 and the second support part 20 in this embodiment can effectively reduce the frictional damage to the display caused by the support device in hard contact. In addition, the soft rubber can also improve the hanging stability of the support device when it is hung on the display.

[0049] Furthermore, in some possible implementations, such as Figure 1As shown, a recessed notch 2021 is formed at the middle of the free end 202 of the second support 20, and protrusions 2022 for abutting against the rear surface of the target object are formed on both sides of the notch 2021.

[0050] The recessed design of the second support portion 20 in this embodiment increases the contact points with the target object and can adapt to displays with irregular back shapes.

[0051] Furthermore, in some possible implementations, such as Figure 6 and Figure 7 As shown, the constant force rotation component 40 is at least one of the following: a torque shaft, a mechanical positioning shaft (e.g., engaged / disengaged at a specific position by a mechanical structure such as a spline, pin, cam, or groove), or a bendable piece (e.g., made of a flexible material).

[0052] Preferably, the constant force rotation component in this application embodiment can adopt two design methods: In the first design, the constant force rotation assembly 40 includes: Shaft core 401, the shaft core 401 is fixed to the rotating end 102 of the first support part 10; Rotary bracket 402, two sets of rotating bracket 402 are provided, the two sets of rotating bracket 402 are rotatably disposed at both ends of the axial direction of the shaft core 401, and at least one of the two sets of rotating bracket 402 is fixed to the connecting end 201 of the second support part 20, so that the second support part 20 can rotate relative to the first support part 10. Friction plate 403 is sleeved on the outer periphery of shaft core 401 and is in frictional engagement with at least one of the two rotating supports 402.

[0053] Preferably, in the first design, the friction plate is a metal friction plate and the rotating bracket 40 is a plastic bracket, that is, in the first design, the constant force rotating component 40 is a metal friction plate type rotating shaft.

[0054] It should be noted that metal friction plate type swivels have high lifespan, reliability, and feel, and high torque consistency. If a POM or nylon bushing is added, the friction noise between the shaft core 401 and the plastic bracket can be eliminated during rotation, and it can also work with the shaft core 401 to limit the rotation angle.

[0055] Furthermore, the second aspect of Embodiment 1 of this application also provides a lamp assembly, which includes a lamp body and a support device provided in the first aspect of Embodiment 1 of this application, wherein the lamp body is rotatably connected to the hanging end 101 of the first support 10.

[0056] Preferably, a pivot or magnetic structure can be provided between the hanging end 101 of the first support part 10 and the lamp body, so that the lamp body can be rotated to adjust the lamp body illumination angle and facilitate the disassembly and assembly of the lamp body.

[0057] It should be noted that although the embodiments of this application use the external device as the lamp body and the target object as the display as specific examples, in some alternative embodiments, the specific form of the external device is not limited to the lamp body, and similarly, the specific form of the target object is not limited to the display.

[0058] Example 2 The only difference between Embodiment 2 and Embodiment 1 is that the constant force rotation component 40 in this embodiment adopts a second design: like Figure 8 As shown, in the second design, the constant force rotation assembly 40 includes: Shaft core 401, shaft core 40 is fixed to the rotating end 102 of the first support part 10; The bushing 404 is pressed onto the outer periphery of the shaft core 401 so that torque is generated when the bushing 404 rotates relative to the shaft core 401. The outer periphery of the bushing 404 is configured as a regular polygonal structure or an irregular structure. The connecting end 201 of the second support part 20 is provided with a mounting hole that is adapted to the outer peripheral structure of the bushing. The bushing 404 is located in the mounting hole and can be limited by the mounting hole in the circumferential direction.

[0059] Preferably, in this embodiment, the bushing 404 is made of regular polygonal or irregularly shaped POM or nylon material, with partial hollowing out. It is assembled with the shaft core 401 by compression to generate torque. The quincunx-shaped bushing provides continuous compressive force to the shaft core 401, extending its service life. It should be noted that the more partial hollowing out (i.e., the more quincunx-shaped holes), the more uniform the torque provided to the shaft core 401, and the smaller the torque abrupt change. Furthermore, the mounting holes on the second support portion 20, designed to mate with the bushing 404, mimic the shape of the bushing 404 and are used to fix and limit the bushing.
