Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a support frame for a physiotherapy lamp. Background Technology

[0002] The infrared light emitted by physiotherapy lamps can generate a thermal effect on human skin, muscles, and subcutaneous tissue, thereby accelerating blood circulation, increasing metabolism, and reducing pain. For example, the TDP physiotherapy device uses heating plates to generate oscillating signals from various elements, forming a specific electromagnetic spectrum. When this electromagnetic spectrum enters the human body along with the infrared rays, it resonates with corresponding elements, significantly increasing the activity of the atomic and molecular clusters containing these elements. This activates enzyme activity, enhances the absorption of deficient elements, adjusts the relative balance of elements in the body, reduces the increase of free radicals, repairs microcirculation channels, and improves the user's immune function and disease resistance. With the continuous improvement of people's quality of life and their increasing emphasis on and pursuit of health, the demand for physiotherapy equipment is also growing.

[0003] Because therapeutic lamps need to irradiate specific areas to achieve therapeutic effects, the angle and position of the light-emitting part relative to the affected area must be constantly adjusted to achieve the optimal result. Traditional rigid support frames are ill-suited for this need. Furthermore, therapeutic lamps often require frequent repositioning for ease of use, but traditional rigid support frames lack gripping areas, making them very inconvenient to move.

[0004] Therefore, there is an urgent need for a flexible and easy-to-use support frame to improve the user experience. Utility Model Content

[0068] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but are not limited to the following embodiments.

[0069] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support frame for a physiotherapy lamp according to this utility model includes: a universal connecting rod 1, a controller housing 2 connected to the universal connecting rod 1, a support rod 3 connected to the controller housing 2, and a base 4 connected to the support rod 3; wherein the universal connecting rod 1, the controller housing 2, the support rod 3, and the base 4 are detachably connected. In this embodiment, the universal connecting rod 1 is a hollow tubular structure, with connecting joints at its opposite ends. The lower joint is connected to the controller housing 2, and the upper joint is connected to the functional components of the physiotherapy lamp.

[0070] In this embodiment, the controller housing 2 includes an outer shell portion 21, an inner shell portion 22, and a light guide ring 23. The outer shell portion 21 and the inner shell portion 22 are coaxially arranged, and the inner shell portion 22 is detachably mounted inside the outer shell portion 21, forming a hollow receiving cavity between them. Furthermore, along the axial direction of the outer shell portion 21, a first end of the inner shell portion 22 is fastened to the outer shell portion 21, and a second end of the inner shell portion 22 is abutted against the outer shell portion 21 based on the light guide ring 23.

[0071] In this embodiment, the light guide ring 23 can be made of PC material. This achieves the light-guiding effect of the ring-shaped body 231 and ensures uniform light distribution during the light-guiding process, resulting in a uniformly illuminated effect when the entire ring-shaped body 231 is illuminated by a light source. This further enhances the aesthetic appearance of the ring-shaped controller housing of this invention.

[0072] With the above configuration, the fixed connection between the outer shell portion 21 and the inner shell portion 22 forms a ring-shaped controller body. This allows for the arrangement of control circuit boards and wiring within the hollow portion of the ring-shaped controller body, fully utilizing the internal hollow area and effectively ensuring the aesthetics of the electrical equipment using this invention. Furthermore, the light guide ring 23 guides the light emitted by the light-emitting component to the outside, indicating the operating status and facilitating user operation.

[0073] Furthermore, by providing a light guide ring 23 at the second end of the inner housing portion 22, the sealing of the entire internal space of the ring controller housing can be further effectively guaranteed, and the flexibility of the light guide ring 23 can also improve the sealing performance between the inner housing portion 22 and the outer housing portion 21. In addition, by mounting the outer housing portion 21, the inner housing portion 22 and the light guide ring 23 together, the end face of the ring controller housing can present a layered effect, making the appearance of this utility model more aesthetically pleasing.

[0074] like Figure 4 As shown, according to one embodiment of the present invention, the light guide ring 23 is detachably nested with the second end of the inner housing portion 22. Based on this nested arrangement, the light guide ring 23 can be pre-installed on the inner housing portion 22 before the outer housing portion 21 is installed, thereby effectively improving installation convenience.

[0075] Combination Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the light guide ring 23 includes: an annular body 231 and a light guide protrusion 232; in this embodiment, the radial dimension of the annular body 231 is reduced along the direction close to the outer shell portion 21; specifically, the annular body 231 can achieve the effect of size reduction by a radially stepped reduction method; wherein, the annular body 231 includes: a first annular portion 2311, a second annular portion 2312 and a third annular portion 2313; in this embodiment, the first annular portion 2311, the second annular portion 2312, the third annular portion 2313, the fourth annular portion 2312, the fifth annular portion 2313, the sixth annular portion 2312, the seventh annular portion 2313, the eighth annular portion 2312, the ninth annular portion 2312, the eleventh annular portion 2313, the eleventh annular portion 2312 ... The second annular portion 2312 and the third annular portion 2313 are coaxially arranged; wherein, along the axial direction of the annular body 231, the first annular portion 2311 and the third annular portion 2313 are staggered; further, the radial dimension of the third annular portion 2313 is smaller than the radial dimension of the first annular portion 2311; and, along the radial direction of the annular body 231, the opposite sides of the second annular portion 2312 are fixedly connected to the ends of the third annular portion 2313 and the first annular portion 2311 respectively, thereby completing the configuration of the entire annular body 231.

[0076] In this embodiment, the first annular portion 2311 and the third annular portion 2313 can be configured as columnar rings, and correspondingly, the second annular portion 2312 can be configured as a plate-shaped ring. This allows the radial direction of the second annular portion 2312 to be perpendicular to the axial direction of the first annular portion 2311 and the third annular portion 2313, respectively, thus achieving a stepped configuration of the entire annular body 231. Alternatively, the second annular portion 2312 can be configured as a conical ring, allowing it to connect to the first annular portion 2311 via its large-diameter end and to the third annular portion 2313 via its small-diameter end. In another embodiment, the first annular portion 2311 and the third annular portion 2313 can also be selectively configured as conical rings. Therefore, by using different forms of the first annular portion 2311, the second annular portion 2312, and the third annular portion 2313, adaptation to the installation position can be achieved, effectively improving the installation accuracy and reliability of this invention.

[0077] Combination Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, along the radial direction of the annular body 231, the first annular portion 2311 is fitted together with the radially outer side of the second end of the inner shell portion 22; along the axial direction of the annular body 231, the second annular portion 2312 is abutted against the side adjacent to the second end of the inner shell portion 22. Through the above arrangement, the annular body 231 can fully abut against the installation position while the inner shell portion 22 is installed, achieving a better sealing effect. Furthermore, the stepped arrangement of the annular body 231 makes the sealing path also resemble a step, further enhancing the sealing effect. In another embodiment, the annular body 231 can be entirely constructed as a conical ring to reduce its size; the structural form is a common conical ring, which will not be elaborated further here. Additionally, the annular body 231 can be entirely circular, elliptical, or other types of annular rings, and its overall form can be adapted to the installation position.

[0078] Combination Figure 4 , Figure 5 and Figure 6As shown, according to one embodiment of the present invention, the light guide protrusion 232 is a PC material protrusion. The PC material provides better light uniformity, resulting in a superior light guiding effect for this solution. In this embodiment, the light guide protrusion 232 and the annular body 231 are integrally formed; wherein, along the axial direction of the annular body 231, the light guide protrusion 232 is disposed on the end face of the third annular portion 2313 away from the second annular portion 2312. In this embodiment, along the axial direction of the annular body 231, the end face of the light-guiding protrusion 232 away from the third annular portion 2313 is the light-receiving surface, and the light-receiving surface is concave. Specifically, along the circumference of the annular body 231, the vertical distance between the two ends of the light-receiving surface and the annular body 231 is greater than the vertical distance between the middle position of the light-receiving surface and the annular body 231, so that the end face of the light-guiding protrusion 232 is concave, thereby effectively increasing the circumferential length of the light-receiving surface, so that it can more easily receive the light emitted by the light source (i.e., the LED point light source). In addition, by setting the light-receiving surface to be concave, it is easier to adjust the distance between the light source and the light-receiving surface, and it can better achieve a state of partially surrounding the light-emitting surface of the light source, so that the received light can be distributed more evenly on the light-receiving surface, which is more beneficial to the uniform transmission of light in the annular body 231.

[0079] In this embodiment, the size of the light-receiving surface is larger than the size of the light source opposite it, thereby ensuring sufficient light-receiving capacity. Furthermore, the light-receiving surface has an axisymmetric structure along the radial direction of the annular body 231, making it easier to align the light-receiving surface and the light source along the axis of symmetry, resulting in more uniform light reception and further improving the uniform annular distribution of the received light within the annular body 231. In addition, the light-receiving surface can be configured as a circular arc surface, an elliptical arc surface, or a parabolic surface; by flexibly setting the form of the light-receiving surface, flexible matching of the positions between the light-receiving surface and the light source can be achieved to achieve uniform light reception. In this embodiment, the concave form of the light-receiving surface is configured as a circular arc surface, thereby conveniently reducing the processing difficulty of the light-receiving surface and lowering its production cost.

[0080] like Figure 5 As shown, according to one embodiment of the present invention, the circumferential length of the light-receiving surface gradually decreases along the direction from the radially outer side to the radially inner side of the third annular portion 2313. This results in the projection of the light-receiving surface presenting a fan-shaped pattern, making it easier for the light-receiving surface to match the dimensions of the end face of the light-guiding protrusion 232 arranged on the annular body 231, thereby more conveniently and uniformly transmitting the received light into the annular body 231.

[0081] Furthermore, in the radial direction of the annular body 231, the width of the light-guiding protrusion 232 is consistent with the width of the end of the light-guiding protrusion 232 arranged on the third annular portion 2313. This ensures that the projection of the light-receiving surface coincides with the end face of the annular body 231, thereby guaranteeing the efficiency of light transmission. In addition, by making the width of the light-guiding protrusion 232 consistent with the width of the end of the light-guiding protrusion 232 arranged on the annular body 231, the two sides of the light-guiding protrusion 232 in the width direction are flush with the side surface of the annular body 231, avoiding light leakage at the connection position and making the light transmission path more reliable.

[0082] Furthermore, the circumferential length of the light guide protrusion 232 gradually decreases along the axial direction of the third annular portion 2313 and away from the third annular portion 2313. With this arrangement, the gradually decreasing circumferential length of the light guide protrusion 232 results in the outer surface 2321 of the light guide protrusion 232 at both circumferential ends being inclined. By making the outer surface 2321 of the light guide protrusion 232 inclined, the angle between it and the light-receiving surface can be significantly increased. This allows for the reflection of a portion of the light over a wide area by the inclined outer surface 2321 while the light-receiving surface receives external light, thereby widely distributing the input light and increasing the distribution range of light entering the annular body 231. The outer surface 2321 can be flat or curved.

[0083] Furthermore, along the direction from the radial outer side to the radial inner side of the third annular portion 2313, the protrusion height of the light guide protrusion 232 at the end away from the third annular portion 2313 gradually decreases, so that the light-receiving surface is inclined relative to the annular body 231. This results in a certain tilt angle between the light-receiving surface and the radial outer side of the annular body 231, allowing the light received by the light-receiving surface to be transmitted to the radial outer side of the annular body 231, thereby achieving the effect of uniform light transmission through reciprocating reflection between the radial outer side and the radial inner side of the annular body 231.

[0084] like Figure 5 As shown, according to one embodiment of this utility model, the outer surface 2321 of the protrusion is a reflective mirror. By setting the outer surface 2321 of the light guide protrusion 232 on both sides as a smooth mirror, the reflection efficiency of light is improved, ensuring sufficient propagation of light to the annular body 231. Furthermore, multiple light guide protrusions 232 are evenly spaced along the circumference of the third annular portion 2313. This effectively increases the number of light receiving positions, making it easier for the received light to be evenly distributed in the annular body 231. Moreover, the brightness and color of the entire light guide ring can be adjusted by controlling the number and type of light source switches, resulting in better light uniformity and light guiding effects.

[0085] Combination Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, a first annular reflective surface 2313a is provided at the end where the third annular portion 2313 is connected to the second annular portion 2312; a second annular reflective surface 2311a is provided at the end where the first annular portion 2311 is connected to the second annular portion 2312; in this embodiment, the first annular reflective surface 2313a and the second annular reflective surface 2311a are conical annular surfaces; wherein, the first annular reflective surface 2313a and the second annular reflective surface 2311a are arranged opposite to each other, and the first annular reflective surface 2313a is arranged opposite to the light guide protrusion 232. Therefore, the external light received by the light-receiving surface on the light-guiding protrusion 232, after being conducted through the third annular portion 2313, is reflected by the first annular reflective surface 2313a into the second annular portion 2312. Further, after propagation through the second annular portion 2312, the light is reflected by the second annular reflective surface 2311a and enters the first annular portion 2311. This achieves the sequential propagation of light from the light-guiding protrusion 232, the third annular portion 2313, the second annular portion 2312, and the first annular portion 2311, realizing the propagation and uniform distribution of external light. In this embodiment, the radial sides of the third annular portion 2313, the axial sides of the second annular portion 2312, and the radial sides of the first annular portion 2311 can each be reflective mirrors, causing the light to reflect back and forth during transmission, thereby achieving a corresponding uniform distribution effect.

[0086] In this embodiment, the first annular reflective surface 2313a and the second annular reflective surface 2311a have the same tilt angle. Thus, the first annular reflective surface 2313a and the second annular reflective surface 2311a are coaxially and parallel to each other, so that the transmission of light is more sufficient and reliable.

[0087] Combination Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the end face of the first annular portion 2311 away from the second annular portion 2312 is a light-emitting surface, and the light-emitting surface is arranged opposite to the second annular reflective surface 2311a. Through this arrangement, the light-emitting surface can fully receive the transmitted light to achieve a uniform distribution on the light-emitting surface, thus achieving the effect of uniform illumination along the annulus.

[0088] It should be noted that the other sides of the first annular portion 2311, the second annular portion 2312, and the third annular portion 2313 that are different from the light-emitting surface, the first annular reflective surface 2313a, and the second annular reflective surface 2311a can be optionally set as smooth mirror surfaces to achieve reciprocating reflection of internal light. Correspondingly, in order to achieve a uniform light effect on the light-emitting surface, the roughness of the light-emitting surface can be set to be greater than that of the other surfaces to achieve a diffuse reflection effect on the entire light-emitting surface, thereby achieving a better uniform light effect.

[0089] Combination Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the light-emitting surface is a conical annular surface; wherein, along the direction from the first annular portion 2311 to the third annular portion 2313, the radial dimension of the light-emitting surface gradually decreases. In this embodiment, the angle between the light-emitting surface and the axial direction of the annular body 231 is greater than the angle between the second annular reflective surface 2311a and the axial direction of the annular body 231. Through the above arrangement, the light-emitting surface is generally arranged at an angle, thereby increasing the effective area for light emission and making it easier to uniformly receive the light to be output. In addition, the light-emitting surface can also be combined with other structures to achieve a better visual effect.

[0090] Combination Figure 7 , Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the shape of the outer shell portion 21 can be flexibly set as needed. For example, the outer shell portion 21 can be set as a circular ring, an elliptical ring, etc. Correspondingly, the shapes of the inner shell portion 22 and the light guide ring 23 are adapted to the shape of their mounting positions on the outer shell portion 21 to achieve continuity of the outer surfaces of the outer shell portion 21, the light guide ring 23, and the inner shell portion 22 after installation. In this embodiment, the cross-section of the inner shell portion 22 is semi-circular, semi-elliptical, semi-rectangular, etc. In the axial direction of the outer shell portion 21, the first end and the second end of the inner shell portion 22 can follow its curved shape so that the first end and the second end are opposite each other, thereby achieving fitting installation with the light guide ring 23 and the ends of the outer shell portion 21 respectively. This ensures the smooth continuity of the entire controller housing surface, effectively ensuring the integrity and smoothness of the entire controller housing shape while achieving complete closure of the formed receiving cavity.

[0091] In this embodiment, the inner shell portion 22 includes a first inner shell structure 221 and a second inner shell structure 222; wherein the first inner shell structure 221 and the second inner shell structure 222 are both annular structures, and the first inner shell structure 221 and the second inner shell structure 222 are coaxially connected; in this embodiment, along the axial direction of the outer shell portion 21, the length of the first inner shell structure 221 and the length of the second inner shell structure 222 can be set to be the same, thereby making the docking position of the first inner shell structure 221 and the second inner shell structure 222 in the middle position, so that the installation of the first inner shell structure 221 and the second inner shell structure 222 is easier. In addition, by dividing the first inner shell structure 221 and the second inner shell structure 222 in the middle position, the forming of each part can be improved, and the overall smoothness of the shape of the entire inner shell portion 22 can be controlled, making the outer surface formed by this invention smoother.

[0092] In this embodiment, the end of the first inner shell structure 221 that is away from the second inner shell structure 222 constitutes the first end of the inner shell portion 22; the end of the second inner shell structure 222 that is away from the first inner shell structure 221 constitutes the second end of the inner shell portion 22.

[0093] Combination Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, according to one embodiment of the present invention, the first inner shell structure 221 and the second inner shell structure 222 are connected by a snap-fit ​​connection. In this embodiment, the first inner shell structure 221 and the second inner shell structure 222 are connected to each other by a first snap-fit ​​structure A that is detachable from each other; wherein, the first snap-fit ​​structure A includes: a first protrusion A1 and a first buckle A2; wherein, the first buckle A2 is generally plate-shaped and has a buckling hole penetrating its body; in this embodiment, the first buckle A2 is disposed on the inner side of the end of the first inner shell structure 221, one end of which is fixedly connected to the first inner shell structure 221, and the other end extends toward the second inner shell structure 222.

Furthermore, the first protrusion A1 is provided on the inner side of the end of the second inner shell structure 222. The mounting position of the first protrusion A1 on the second inner shell structure 222 corresponds to the position of the fastening hole after the first inner shell structure 221 and the second inner shell structure 222 are mated together, thereby facilitating a convenient and reliable fastening connection between the first protrusion A1 and the first retaining ring A2. In another embodiment, the mounting positions of the first protrusion A1 and the first retaining ring A2 on the inner shell portion 22 can be interchanged; that is, the first protrusion A1 can be provided on the first inner shell structure 221, and the first retaining ring A2 can be provided on the second inner shell structure 222. In this embodiment, multiple first snap-fit ​​structures A are provided at equal intervals along the circumference of the inner shell portion 22.

[0094] Combination Figure 4 , Figure 7 and Figure 8As shown, according to one embodiment of the present invention, the ends of the first inner shell structure 221 and the second inner shell structure 222 are abutted together by a stepped structure. In this embodiment, annular protrusions are provided at the ends of the first inner shell structure 221 and the second inner shell structure 222, so that the ends of the first inner shell structure 221 and the second inner shell structure 222 form a stepped structure that fits together. This effectively ensures the docking accuracy and connection reliability of the ends of the first inner shell structure 221 and the second inner shell structure 222. Specifically, a first annular protrusion is provided at the end of the first inner shell structure 221, and a second annular protrusion is provided at the end of the second inner shell structure 222. The radial dimension of the first annular protrusion is larger than the radial dimension of the second annular protrusion, so that when the first inner shell structure 221 and the second inner shell structure 222 are docked together, the first annular protrusion and the second annular protrusion are nested together to ensure the realization of the corresponding stepped structure. Furthermore, to ensure the surface flatness and shape consistency of the docking position, the radial dimension of the first annular protrusion and the second annular protrusion after being nested together can be made consistent with the radial dimension of the ends of the first inner shell structure 221 and the second inner shell structure 222, so as to effectively ensure the smoothness and integrity of the surface.
