Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature. In the description of the present disclosure, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

In the present disclosure, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integral; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

In the present disclosure, unless expressly stated or limited otherwise, a first feature "on" or "under" a second feature may be directly contacting the second feature or the first and second features may be indirectly contacting each other through intervening media. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

In the related art, the powell prism, the collimating lens and the laser are arranged in sequence along the light path direction, and the laser emitted by the laser diode can output in-line laser after passing through the collimating lens and the powell prism in sequence. Wherein, the forming process of the in-line laser comprises the following steps: the laser emitted by the laser forms two club-shaped light spots after passing through the collimating lens, the two club-shaped light spots form a linear laser after passing through the Baville prism, but the actual position of the collimating lens deviates from the preset position, so that the shape of the actually formed laser is in a shape of one end being thin and the other end being thick, in other words, the shape of the actually formed laser is similar to an isosceles trapezoid, and the preset shape of the laser is a rectangle, so that the shape deviation of the laser emitted by the laser is large, and the use requirement cannot be met.

Through careful analysis, the inventor of the present disclosure believes that the main reason for the above problem is that the laser emitted by the laser depends on the position accuracy of the collimating lens, which depends on the lens seat carrying the collimating lens, the lens seat is of a hollow structure, the collimating lens is installed in the lens seat, and in addition, the outer wall of the lens seat is tapped with an external thread and is used for being matched with the thread of the light source channel of the housing, so that the position of the collimating lens in the light source channel can be changed to realize focusing. However, due to the threaded fit between the lens holder and the inner wall of the light source channel, the coaxiality and stability of the lens holder during the assembling and adjusting process are low, so that the deviation between the actual position of the lens holder after the installation and the preset position is large, and the quality of laser emitted by the laser can be affected. The coaxiality indicates the position of the lens seat in the light source channel, the stability indicates an index that the position of the lens seat does not change in the process of focusing the collimating lens, and the assembling and adjusting process indicates a process of assembling the lens seat into the light source channel and modulating the collimating lens.

In view of this, the present disclosure provides a light source device, a lens holder of the light source device has a threaded portion and a positioning portion which are coaxially disposed, the threaded portion is used for being in threaded fit with an inner wall of a light source channel, so that the lens holder can move in the light source channel to meet a focusing requirement of a collimating lens, the positioning portion is in contact with an inner wall surface of the light source channel, so that coaxiality accuracy of the lens holder in an assembling and adjusting process can be improved, in addition, the positioning portion and the threaded portion are mutually matched, and the coaxiality accuracy of the lens holder in the assembling and adjusting process is further improved. In addition, this disclosure still overlaps on the lens holder and is equipped with elastically deformable's first damping circle, first damping circle respectively with the inner wall and the lens holder butt of light source passageway to exert a damping force to the lens holder at the dress in-process of transferring, help improving the stability of lens holder, make the focusing process stable, and can improve focusing accuracy and uniformity.

It should be noted that the lens holder and the first damping ring provided in the present disclosure may be applied to any structure having a requirement for coaxiality, which is not specific herein, for example, two lenses arranged at an interval in the optical axis direction perform focusing. The light emitted from the light source device may be laser light or visible light, and the color of the laser light or visible light may be red, blue, green, or the like. When the light emitted by the light source device is laser, the light source device may be referred to as a laser.

The following describes the light source device, the 3D camera and the terminal provided in the present disclosure in detail by taking the light source device as a laser as an example and combining specific embodiments.

Fig. 1 is a perspective view of a light source device provided by the present disclosure. Fig. 2 is a cross-sectional view of a light source device provided by the present disclosure. Fig. 3 is a perspective view of a housing provided by the present disclosure. Fig. 4 is a perspective view of a lens housing provided by the present disclosure.

As shown in fig. 1 and 2, the present disclosure provides a light source device 100, the light source device 100 at least including: a housing 110, and a collimator lens assembly 120. The housing 110 is used for carrying components such as the collimator lens assembly 120, the powell prism assembly 150, and the light source assembly 130. As shown in fig. 3, the housing 110 has a light source channel 111 penetrating through the housing 110, in other words, the housing 110 is a hollow structure, and is configured to accommodate the collimating lens assembly 120, a part of the powell prism assembly 150, and a part of the light source assembly 130, so that the collimating lens assembly 120, the powell prism assembly 150, and the light source assembly 130 are sequentially arranged along an axial direction of the light source channel 111, and on the other hand, the collimating lens assembly 120, the powell prism assembly 150, and the light source assembly 130 can be protected, and the size of the light source apparatus 100 can be reduced.

It should be noted that the shape of the housing 110 may be a circular shape, a prismatic shape, or the like, and is not particularly limited herein. For example, referring to fig. 3, the housing 110 has a rectangular parallelepiped shape.

Wherein, as shown in fig. 2, the collimating lens assembly 120 is installed in the light source channel 111, specifically, the collimating lens assembly 120 is located between the light source assembly 130 and the powell prism assembly 150. The collimating lens assembly 120 includes a tubular structure lens housing 121 and an elastically deformable first damping ring 122. The inner wall of the lens holder 121 defines a through-hole for mounting a collimating lens so that the collimating lens can be mounted in the light source passage 111 through the lens holder 121. The lens holder 121 includes a threaded portion 1211 and a positioning portion 1212, which are coaxially disposed. The thread portion 1211 is configured to be in thread fit with an inner wall of the light source channel 111, so that the collimating lens can be driven to move along the axial direction of the light source channel 111 by rotating the lens holder 121, so as to change the position of the collimating lens in the light source channel 111, thereby achieving focusing. The positioning portion 1212 is used to contact the inner wall surface of the light source channel 111, and can increase the positioning area of the lens holder 121, which helps to further improve the coaxiality of the lens holder 121 during the assembling process.

It can be understood that the longitudinal cross-section of the light source channel 111, the threaded portion 1211 and the positioning matching portion is circular to ensure that the lens holder 121 can rotate around the rotation axis, therefore, the threaded portion 1211 and the positioning portion 1212 have cylindrical shapes, in other words, the positioning portion 1212 can correspond to one optical axis, and the threaded portion 1211 can correspond to one screw.

It should be noted that the thread portion 1211 and the positioning portion 1212 may be integrally formed or detachably connected, for example, in the present disclosure, the thread portion 1211 and the positioning portion 1212 are integrally formed, which may improve the connection strength between the thread portion 1211 and the positioning portion 1212, on the one hand, and the manufacturing efficiency of the lens holder 121, on the other hand.

As shown in fig. 2 and 4, a first annular groove 1214 surrounding the lens holder 121 is formed on the outer wall of the lens holder 121, in other words, the first annular groove 1214 is disposed around the collimating lens. The first damping ring 122 is sleeved on the lens holder 121, and a part of the first damping ring 122 is embedded in the first annular groove 1214 and is used for abutting against the inner wall of the light source channel 111, so that in the assembling and adjusting process, a damping force can be applied to the lens holder 121 through the first damping ring 122, the stability of the lens holder 121 can be improved, the position of the lens holder 121 can be prevented from changing, and the focusing accuracy and consistency can be improved.

It should be noted that, because the first damping ring 122 is sleeved on the lens holder 121, the stability of the lens holder 121 in the assembling and adjusting process can be improved, and accordingly, the difficulty in assembling and adjusting the lens holder 121 is reduced, which is beneficial to improving the production efficiency of the light source device 100.

In some possible embodiments, as shown in fig. 4, the lens holder 121 further includes: the intermediate portion 1213. Wherein opposite ends of the intermediate portion 1213 are tightly coupled to the coupling ends of the screw portion 1211 and the positioning portion 1212, respectively, and the intermediate portion 1213 has an outer diameter smaller than the outer diameters of the positioning portion 1212 and the screw portion 1211 and defines a second annular groove 1215 together with the positioning portion 1212 and the screw portion 1211. With this arrangement, the fastening effect of the lens holder 121 and the housing 110 can be improved.

The outer wall of the housing 110 is provided with a glue injection hole 112 communicated with the light source channel 111, and after the position of the lens holder 121 in the light source channel 111 is adjusted, glue can be injected between the lens holder 121 and the light source channel 111 through the glue injection hole 112, so that the lens holder 121 and the housing 110 are fixed. The injected compound injected from the compound injection hole 112 is divided into two parts, one part is located in the second annular groove 1215, and the other part is located between the lens holder 121 and the light source channel 111, and due to the arrangement of the second annular groove 1215, the injected compound is clamped with the lens holder 121, and the contact area between the compound and the lens holder 121 can be increased, so that the fastening effect of the lens holder 121 and the housing 110 can be improved.

In some examples, as shown in fig. 2, the inner wall of the portion of the light source passage 111 that mates with the lens holder 121 defines a step surface that can engage the glue injection between the lens holder 121 and the light source passage 111 to improve the fastening effect of the lens holder 121 to the light source passage 111 on the one hand, and can cooperate with the second annular groove 1215 to improve the positional accuracy of the lens holder 121 within the light source passage 111 on the other hand.

In some possible embodiments, the first annular groove 1214 may be disposed on an outer wall of the positioning portion 1212 (as shown in fig. 4, for example), or the first annular groove 1214 may be disposed on an outer wall of the threaded portion 1211 (not shown in the drawings), so as to ensure that the first damping ring 122 can interfere with an inner wall of the light source passage 111.

It can be understood that when the first annular groove 1214 is provided on the outer wall of the positioning portion 1212, which helps to reduce the resistance between the first damping ring 122 and the light source passage 111, the first damping ring 122 can be prevented from being damaged.

It should be noted that the first annular portion may be provided on the intermediate portion 1213, in addition to the positioning portion 1212 and the threaded portion 1211, and is not particularly limited herein.

In some possible embodiments, the first damping ring 122 is made of an elastically deformable material, which ensures that a damping force is applied to the lens holder 121 during the assembling and adjusting process, for example, the first damping ring may be a rubber damping ring, a silicone damping ring, a fluorine rubber damping ring, or a foam damping ring.

Fig. 5 is a perspective view of a light source assembly provided by the present disclosure. Fig. 6 is a cross-sectional view of a light source assembly provided by the present disclosure.

In this embodiment, since the light source apparatus 100 is a laser, the light emitted by the light source apparatus 100 is a laser, and the shape of the laser may further reduce the shape deviation of the laser by adjusting the position of the light source generator 131, for example, in some possible embodiments, as shown in fig. 5 and 6, the light source apparatus 100 may further include: a light source assembly 130, the light source assembly 130 including at least a light source generator 131, a fixing assembly 132, and a fastening assembly 133. The fixing assembly 132 is used to fix the light source generator 131, and specifically, the fixing assembly 132 may include a fixing plate 1321 and a mounting seat 1322. The mounting seat 1322 is positioned in the light source passage 111 and has a mounting through hole 13221 penetrating through the mounting seat 1322, and the mounting seat 1322 is positioned between the fixing plate 1321 and the collimator lens assembly 120.

In the present disclosure, the light source generator 131 is used for emitting a laser beam, as shown in fig. 6, a portion of the light source generator 131 is installed in the installation through hole 13221, and opposite ends of the light source generator 131 abut against the installation seat 1322 and the fixing plate 1321, respectively, so that the fixing plate 1321 and the installation seat 1322 fix the light source generator 131, and the light source generator 131 can be driven to rotate by rotating the installation seat 1322 or the fixing plate 1321, so as to adjust an angle of the laser beam emitted by the light source generator 131. It should be appreciated that any device capable of emitting laser light may be used for the light source generator 131, for example, the light source generator 141 may be a laser diode.

The fastening assembly 133 fastens the fixing plate 1321 and the mounting seat 1322, so that the two opposite ends of the light source generator 131 abut against the fixing plate 1321 and the mounting base, respectively, and fastens the fixing assembly 132 and the housing 110.

When it is necessary to adjust the light source generator 131, the fixing plate 1321 and the mounting seat 1322 are first fastened by the fastening assembly 133 so that the light source generator 131 defines an integral body with the fixing plate 1321 and the mounting seat 1322, and then the angle of the laser beam can be adjusted by rotating the fixing plate 1321 to rotate the light source generator 131. After the light source generator 131 is adjusted, the fixing assembly 132 is fastened to the housing 110 by the fastening assembly 133, so that the position of the light source generator 131 relative to the housing 110 is maintained.

Since the light source generator 131 is respectively abutted to the fixing plate 1321 and the mounting seat 1322, in other words, the fixing component 132 is fastened to the light source generator 131, and the light source generator 131 and the fixing component 132 form an integral structure, the light source generator 131 can be rotated by a predetermined angle, which is helpful for improving the precision of adjusting the angle of the laser beam, so that the laser emitted by the light source device 100 meets the use requirement.

In some examples, as shown in fig. 5, the light source generator 131 includes a plate-shaped body portion 1311 and two rod-shaped electrode portions 1312, first ends of the two electrode portions 1312 are electrically connected to one end of the body portion 1311 near the fixing plate 1321, respectively, and second ends of the two electrode portions 1312 are electrically connected to the circuit board 140 of the light source apparatus 100, respectively. At least a part of the body 1311 is located in the mounting through hole 13221, and opposite ends of the body 1311 abut against the mounting seat 1322 and the fixing plate 1321, respectively, so that the light source generator 131 abuts against the mounting seat 1322 and the fixing plate 1321, respectively.

As shown in fig. 5, in order to electrically connect the electrode portions 1312 to the circuit board 140, the fixing plate 1321 is provided with electrode through holes through which the electrode portions 1312 pass. In addition, each electrode portion 1312 may correspond to one electrode through hole, or two electrode portions 1312 may share one electrode through hole (as shown in fig. 5), which is not particularly limited herein.

It is understood that the body portion 1311 may be located entirely within the mounting through-hole 13221, or that a portion of the body portion 1311 may be located within the mounting through-hole 13221. When the body 1311 is entirely located in the mounting through hole 13221, a portion of the fixing plate 1321 may be located in the mounting through hole 13221 and abut against the body 1311. Alternatively, when the body 1311 is entirely located in the mounting through hole 13221, correspondingly, the end surface of the body 1311 abutting against the fixing plate 1321 is flush with the end surface of the mounting seat 1322 abutting against the fixing plate 1321. For example, as shown in fig. 6, in the present disclosure, an end surface of the body portion 1311 abutting against the fixing plate 1321 is flush with an end surface of the mounting seat 1322 abutting against the fixing plate 1321, and thus, the size of the light source device 100 in the axial direction of the light source passage 111 is facilitated to be reduced, so that the volume size of the light source device 100 is reduced.

Fig. 7 is a perspective view of a mount provided by the present disclosure at a first angle.

To achieve abutment of the mounting seat 1322 with the light source generator 131, in some possible embodiments, along the axial direction of the light source passage 111, as shown in fig. 7, the mounting through-hole 13221 may include a first through-hole section 132211 and a second through-hole section 132212 that are coaxially disposed. Wherein the inner wall of the first through-hole section 132211 and the inner wall of the second through-hole section 132212 together define a stepped surface against which the light source generator 131 abuts.

It is understood that one of the first through-hole section 132211 and the second through-hole section 132212 has an inner diameter smaller than that of the other, for example, the inner diameter of the first through-hole section 132211 is smaller than that of the second through-hole section 132212, and the second through-hole section 132212 is located between the fixing plate 1321 and the first through-hole section 132211 at this time, that is, the second through-hole section 132212 is disposed against the fixing plate 1321, which is not particularly limited herein.

To ensure the relative position of mount 1322 and light source generator 131, in some examples, a positioning structure is also included. One part of the positioning structure is located on the through-hole section having the larger inner diameter among the first through-hole section 132211 and the second through-hole section 132212, and the other part of the positioning structure is located on the outer wall of the light source generator 131.

Taking the light source generator 131 defined by the body portion 1311 and the electrode portion 1312 as an example, the positioning structure includes a first gap and a second gap penetrating the body portion 1311, and as shown in fig. 7, the positioning structure further includes a first filling portion 13224 and a second filling portion 13225 provided on an inner wall of the mounting through hole 13221. The first filling portion 13224 is configured to be inserted into the first notch, and the second filling portion 13225 is configured to be inserted into the second notch.

Fig. 8 is a perspective view of a mount provided by the present disclosure at a second angle.

In some possible embodiments, as shown in fig. 8, the mount 1322 includes a tubular portion 13222 and an abutment portion 13223. Wherein the inner wall of the tubular portion 13222 defines a mounting through-hole 13221. The abutting portion 13223 is provided on an outer wall of the tubular portion 13222 and is configured to abut against an inner wall of the light source passage 111 to limit the position of the mount 1322 in the light source passage 111.

In order to ensure the position of the restricting mount 1322 and the mounting of the mount 1322 within the light source passage 111, an inner wall of a portion of the light source passage 111 where the mount 1322 is fitted defines a stepped surface against which the abutting portion 13223 abuts.

It is understood that the tubular portion 13222 and the abutment portion 13223 can be of a unitary construction, which can help to increase the strength of the connection of the abutment portion 13223 and the tubular portion 13222, or the tubular portion 13222 can be fixedly connected to the abutment portion 13223 by welding, screwing, or the like.

In some examples, the abutment portion 13223 includes a plurality of abutment plate portions provided at intervals in the circumferential direction of the tubular portion 13222.

In other examples, as shown in fig. 8, the abutting portion 13223 is an annular plate portion, and the abutting portion 13223 is fitted over the tubular portion 13222 and is configured to abut against an inner wall of the light source passage 111. The end surface of the abutting portion 13223 close to the fixing plate 1321 may be flush with the end surface of the tubular portion 13222 close to the fixing plate 1321, which helps to reduce the difficulty of manufacturing the mounting seat 1322.

In order to improve the stability of the light source generator 131 during rotation, in some possible embodiments, as shown in fig. 2 and 6, the light source assembly 130 further includes: a second damping band 134 that is elastically deformable. Wherein, the outer wall of the mounting seat 1322 is provided with a third annular groove 135 surrounding the light source generator 131. The second damping ring 134 is sleeved on the mounting seat 1322, and a part of the second damping ring 134 is embedded in the third annular groove 135 and is abutted against the inner wall of the light source channel 111, so that in the rotating process, the mounting seat 1322 can receive the damping force applied to the mounting seat 1322 by the second damping ring 134, so that the rotating stability of the mounting seat 1322 is improved, and the precision of adjusting the angle of the laser beam can be improved.

It is understood that the second damping ring 134 is made of an elastically deformable material to ensure that a damping force is applied to the mounting seat 1322 during the assembling and adjusting process, for example, the second damping ring 134 may be a rubber damping ring, a silica gel damping ring, a fluorine rubber damping ring, or a foam damping ring.

Note that, as shown in fig. 8, the third annular groove 135 may be provided in the tubular portion 13222, or when the abutting portion 13223 is an annular plate portion, the third annular groove 135 may be provided in an outer wall of the annular plate portion, which is not particularly limited.

Of course, the temperature measuring end of the temperature measuring chip 141 may not detect the temperature of the fixing plate 1321 through the heat conductive silica gel, and the temperature measuring end of the temperature measuring chip 141 is located in the accommodating groove 13211 at this time, and in addition, the temperature measuring end of the temperature measuring chip 141 may be in contact with or not in contact with the fixing plate 1321, and the temperature measuring chip 141 may detect the temperature of the fixing plate 1321, so that the temperature of the light source generator 131 may be monitored. It can be understood that the temperature measuring chip 141 can be located in the accommodating slot 13211, so as to reduce the size of the light source device 100.

It is understood that the temperature measuring chip 141 is equivalent to a temperature sensor, so that the temperature of the fixing plate 1321 or the heat conductive silicone can be detected.

Since the fixing plate 1321 and the mounting seat 1322 have high thermal conductivity, heat generated by the light source generator 131 is transferred to the mounting seat 1322 and the fixing plate 1321, and the temperature measuring chip 141 can indirectly monitor the temperature of the light source generator 131. The fixing plate 1321 may be made of a metal with high thermal conductivity, for example, the fixing plate 1321 is a copper plate, which is not limited in particular.

In one possible implementation, as shown in fig. 9, the fixing plate 1321 includes a main body portion 13212 and an indicating portion 13213.

The indication portion 13213 is disposed on a side wall of the main body portion 13212 and is configured to cooperate with an indication marking line disposed on the housing 110 to ensure the position of the light source generator 131, and in addition, the indication portion 13213 can drive the fixing plate 1321 to rotate.

In order to reduce the axial size of the light source device 100, the main body portion 13212 may be disposed in the light source passage 111, and the housing 110 may be provided with an indication notch into which the indication portion 13213 is inserted.

Fig. 10 is a perspective view of a circuit board provided by the present disclosure.

The second fastening member 1332 is used to fasten the fixing assembly 132 to the housing 110. So configured, it is possible to realize adjustment of the angle of the laser beam and fixing of the position of the light source generator 131 in the light source channel 111.

The first fastening device 1331 may be a first screw or a first bolt, for example, in some examples, the first fastening device 1331 may be a first screw, and correspondingly, in some examples, the fixing plate 1321 and the mounting seat 1322 are each provided with a threaded hole in threaded fit with the first screw, so that the light source generator 131, the fixing plate 1321 and the mounting seat 1322 abut against each other. In other examples, a through hole for a first screw to pass through is formed in the fixing plate 1321, a threaded hole for threaded engagement with the first screw is formed in the mounting seat 1322, and after the first screw is engaged with the fixing plate 1321 and the mounting seat 1322, the first screw abuts against the fixing plate 1321 and is in threaded engagement with the mounting seat 1322.

In order to improve the connection effect of the fastening assembly 133 and the housing 110, the number of the second fastening connections is plural, for example, the number of the second fastening members 1332 is 2, 3, 4, 5, etc., and is not particularly limited herein.
