[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0055] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0056] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] The following describes an optical path switching device 1 provided by an embodiment of this utility model with reference to the accompanying drawings. Figure 1-8The optical path switching device 1 includes a guide mechanism 11, a sliding mechanism 12, and a converter 13.

[0058] refer to Figure 4 The guiding mechanism 11 includes a guiding body 111 with a guiding cavity 112 and a magnetic mating assembly 113 fixedly disposed on the bottom wall of the guiding cavity 112.

[0059] In some embodiments, the guide body 111 is used to support the sliding mechanism 12, the adapter 13, and the optical path components located on the adapter 13, and can meet load requirements. The guide cavity 112 is a cavity with an opening on one side to accommodate at least a portion of the sliding mechanism 12. The shape of the guide cavity 112 can be set according to device requirements, see reference. Figure 6 It can be configured as a cavity with a flat and sloping bottom wall to facilitate the installation of magnetic mating assembly 113 on the flat bottom wall.

[0060] In some embodiments, reference is made to Figure 2 The magnetic mating assembly 113 includes at least one magnetic element 113a. The number of magnetic elements 113a in the magnetic mating assembly 113 is positively correlated with the effective stroke of the magnetic assembly 121. The effective stroke refers to the maximum distance that the magnetic assembly 121 can actually move within the magnetic field range of the magnetic mating assembly 113. At least two magnetic elements 113a are joined with or without gaps; the longer the joint length, the longer the effective stroke, and vice versa. Thus, by limiting the movable stroke of the magnetic assembly 121 through the joined magnetic elements 113a, the movable range of the slider assembly 122 is limited, enabling free control and adjustment of the optical path assembly's movement stroke, and allowing compatibility with light source access systems with different numbers of light sources. Compared to stepper motors, this embodiment offers higher repeatability, customizable stroke, shorter overall length, and simpler operation.

[0061] In some embodiments, reference is made to Figure 2 The magnetic mating assembly 113 includes at least two magnetic elements 113a, which are arranged in an array to limit the effective stroke of the magnetic assembly 121 along the linear motion direction of the adapter 13. The arrayed magnetic elements 113a can provide a magnetic field for linear drive to achieve stable linear motion of the magnetic assembly 121 and reduce the difficulty of structural or electromagnetic field adjustment of the magnetic assembly 121.

[0062] In one embodiment, reference Figure 1-4 At least two magnetic components 113a are joined together along the linear movement direction of the slider assembly 122 to form a linearly arranged magnetic mating assembly 113. In one embodiment, the magnetic component 113a is a magnetic stator.

[0063] refer to Figure 5-6The sliding mechanism 12 includes a magnetic component 121 and a slider assembly 122 having a receiving cavity 122a. The magnetic component 121 is embedded in the receiving cavity 122a and magnetically coupled with the magnetic mating component 113. The slider assembly 122 is slidably connected to the guide cavity 112.

[0064] In some embodiments, the magnetic component 121 includes a magnetic core and a first electromagnetic element. The first electromagnetic element is wound around the magnetic core. When the first electromagnetic element is energized, the magnetic component 121 is electromagnetically coupled to the magnetic mating component 113. The magnetic core can be a ferromagnetic block, such as an iron core. The first electromagnetic element can be an electromagnetic coil, arranged around the magnetic core, which generates an electromagnetic field when energized, thereby electromagnetically coupling the combination of the magnetic core and the first electromagnetic element to the magnetic mating component 113. This achieves stable sliding of the slider component 122 and facilitates the electromagnetic control of the magnetic component 121.

[0065] In other embodiments, the magnetic component 121 includes a second electromagnetic element, which is electromagnetically coupled to the magnetic coupling component 113. Specifically, the second electromagnetic element can be non-magnetic when not energized, and forms an electromagnetic field coupled to the magnetic field of the magnetic coupling component 113 when energized, thereby reducing the magnetic influence of the magnetic component 121 on the optical component 3 and improving the applicability of the optical path switching device 1.

[0066] Specifically, refer to Figure 5-6 The magnetic component 121 is fixedly disposed in the receiving cavity 122a, which is capable of accommodating at least a portion of the magnetic component 121. The slider assembly 122 is capable of sliding in the guide cavity 112 in coordination with the magnetic component 121. During the sliding process, the magnetic component 121 is driven by the magnetic field of the magnetic mating assembly 113.

[0067] In some embodiments, reference is made to Figure 5-6 The receiving cavity 122a has a receiving cavity opening facing the magnetic mating assembly 113. One side of the magnetic assembly 121 is exposed through the receiving cavity opening and is disposed opposite to the magnetic mating assembly 113. This allows the magnetic assembly 121 to be fixedly embedded within the receiving cavity 122a and to have an exposed surface facing the magnetic mating assembly 113. This facilitates the magnetic coupling assembly and calibration between the magnetic assembly 121 and the magnetic mating assembly 113, improving the integration of the installation while reducing the difficulty of drive assembly. In a preferred embodiment, refer to... Figure 6 The exposed surface of the magnetic component 121 exposed to the cavity opening is positioned opposite to the magnetic mating component 113.

[0068] In some embodiments, reference is made to Figure 6 There is a gap between the magnetic component 121 and the guide body 111, and there is also a gap between the magnetic component 121 and the magnetic mating component 113. It is fixed only by the slider component 122, which can avoid the movement and friction of the magnetic component 121 and avoid mechanical wear.

[0069] refer to Figure 6 One of the sidewalls of the guide cavity 112 and the slider assembly 122 is provided with a guide groove 114, and the other sidewall of the guide cavity 112 and the slider assembly 122 is provided with a guide protrusion 122b that slides with the guide groove 114. The slider assembly 122 is slidably connected to the sidewall of the guide cavity 112 through the guide groove 114 and the guide protrusion 122b. The sidewall of the guide cavity 112 is connected to its bottom wall, preferably with both opposite sidewalls of the guide cavity 112 slidably connected to the slider assembly 122. The sliding connection is achieved through the groove and protrusion engagement, allowing the sidewall of the guide cavity 112 to serve as a sliding load-bearing position. The magnetic field component in the direction of gravity provided by the magnetic engagement assembly 113 can reduce the force on the sliding connection part and reduce sliding friction.

[0070] In one embodiment, reference Figure 6 The guide cavity 112 has a guide groove 114 on its sidewall, and the slider assembly 122 has a guide protrusion 122b on its sidewall, which engages with the guide groove 114. In another embodiment, the guide cavity 112 has a guide protrusion 122b on its sidewall, and the slider assembly 122 has a guide groove 114 that slides with the guide protrusion 122b on its sidewall.

[0071] Specifically, the guide groove 114 and the guide protrusion 122b restrict the movement direction of the slider assembly 122. Preferably, the guide groove 114 is an arc-shaped groove, and the guide protrusion 122b is an arc-shaped protrusion. The guide groove 114 and the guide protrusion 122b can also be other shapes.

[0072] In some embodiments, reference is made to Figure 4 The slider assembly 122 includes a slider 122c and an end cap 122d fixedly connected to the slider 122c. The slider 122c is fixedly connected to the adapter 13. The end cap 122d is located on at least one side of the slider 122c in the sliding direction. At least one side of the end cap 122d is provided with a guide groove 114 or a guide protrusion 122b to slide and engage with at least one side wall of the guide cavity 112. The adapter 13 and the magnetic assembly 121 can be disposed opposite to each other on both sides of the slider 122c. The adapter 13 is fixed by the slider 122c, and a sliding connection is achieved by the end cap 122d on the side of the slider 122c. This reduces the sliding friction area and facilitates component replacement after sliding wear, thereby reducing maintenance difficulty and cost.

[0073] In some embodiments, the end cap 122d and the slider 122c are integrally formed, while in other embodiments, the end cap 122d and the slider 122c are separate parts.

[0074] In the preferred embodiment, reference Figure 4The slider 122c has end caps 122d on both sides in the sliding direction, and both end caps 122d are slidably connected to the side wall of the guide cavity 112.

[0075] Specifically, refer to Figure 5-6 The two sides of the end cap 122d are provided with guide grooves 114 or guide protrusions 122b to slide in connection with the side wall of the guide cavity 112.

[0076] The end cap 122d and the slider 122c are enclosed to form a receiving cavity 122a with an opening at at least one end, so as to save installation space and reduce the weight of the slider 122c, thereby reducing the weight of the slider assembly 122.

[0077] In some embodiments, reference is made to Figure 2-4 The optical path switching device 1 also includes a reinforcing member 14, which is located on at least one side of the sliding direction of the slider assembly 122 and is fixedly connected to the slider assembly 122 to improve the load-bearing capacity and structural strength of the slider assembly 122.

[0078] The reinforcing member 14 is disposed on the side of the end cap 122d opposite to the slider 122c, that is, the end cap 122d is disposed between the reinforcing member 14 and the slider 122c. Preferably, the reinforcing member 14 is disposed on both sides of the slider 122c.

[0079] In some embodiments, reference is made to Figure 2-6 The optical path switching device 1 also includes a buffer 15, which is located on the side of the reinforcing member 14. When the slider assembly 122 moves to the limit position relative to the guide body 111, the slider assembly 122 achieves motion buffering when it moves to the limit position through the buffer 15 and the abutment position of the limit position, thus avoiding component damage and motion accuracy impact caused by hard contact.

[0080] The adapter 13 has an optical component mounting position 131 for connecting the optical component 3. The adapter 13 is fixedly connected to the slider assembly 122 and is located on the side of the slider assembly 122 opposite to the guide cavity 112. The magnetic component 121 can be driven by the magnetic engagement component 113 to drive the slider assembly 122 to slide in the guide cavity 112, thereby driving the adapter 13 to move linearly relative to the guide body 111, so as to realize the linear movement of the optical component 3 and thus perform optical path switching.

[0081] In summary, the above technical solution provides a guide cavity 112 in the guide body 111 that can accommodate the magnetic mating component 113 and the slider component 122. The magnetic component 121, which is magnetically coupled to the magnetic mating component 113, is embedded in the receiving cavity 122a of the slider component 122. The adapter 13 and the slider component 122 are located on the same side of the guide body 111, thereby highly concentrating the core components in the guide body 111, improving the integration of the device. Furthermore, the use of integrated magnetic coupling magnetic drive can effectively reduce drive wear, transport vibration and noise, and improve repeatability. At the same time, the slider component 122 is slidably connected to the guide cavity 112, and the guide body 111 bears the transport load, thereby ensuring transport stability and meeting the requirements of large loads.

[0082] In some embodiments, the optical component 3 and the slider assembly 122 are fixedly connected to both sides of the adapter 13, respectively. There is a gap between the adapter 13 and the guide body 111, and the optical component mounting position 131 is located on the side of the adapter 13 opposite to the guide cavity 112, so as to facilitate the connection and transport of the optical component 3.

[0083] In some embodiments, when the adapter 13 moves to its limit position with the slider assembly 122, there is a gap between the adapter 13 and the contact position.

[0084] In some embodiments, reference is made to Figure 1-4 The optical path switching device 1 also includes a bracket 16, specifically comprising a bracket side plate 161, a bracket back plate 162, and a bracket base plate 163. The bracket side plate 161, bracket back plate 162, and bracket base plate 163 enclose a bracket cavity 164. The guide body 111 is fixedly disposed in the bracket cavity 164. The bracket side plate 161 can limit the sliding stroke of the slider assembly 122. That is, the bracket side plates 161 on both sides of the bracket 16 are provided with abutment positions for the slider assembly 122 to limit the sliding stroke of the slider assembly 122. The bracket 16 achieves the fixation of the guide body 111 and the limiting of the slider assembly 122, preventing the slider assembly from slipping off.

[0085] In some embodiments, the bracket side plate 161, the bracket back plate 162, and the bracket bottom plate 163 are fixedly connected, and the guide body 111 is fixedly connected to the bracket side plate 161 and the bracket back plate 162 respectively.

[0086] In some embodiments, reference is made to Figure 1-3The optical path switching device 1 also includes a wire harness receiving assembly 17 located in the support cavity 164 and adjacent to the guide body 111. The wire harness receiving assembly 17 includes a deformable wire harness protective sleeve 171, a movable end connector 172, and a fixed end connector 173. The wire harness protective sleeve 171 has a wire harness receiving cavity 122a with openings at both ends. The movable end of the wire harness protective sleeve 171 is fixedly connected to the adapter 13 through the movable end connector 172, and the fixed end of the wire harness protective sleeve 171 is fixedly connected to the support 16 through the fixed end connector 173. The movable end of the wire harness protective sleeve 171 can move with the adapter 13, and the wire harness protective sleeve 171 can deform during the movement of the movable end, so as to drive the wire harness 21 of the optical path switching device 1 to deform and move with the adapter 13, thereby providing protection and freedom of movement for the wire harness 21 while concentrating the wire harness 21.

[0087] In a preferred embodiment, the wire harness protective sleeve 171 is positioned along the sliding direction of the slider assembly 122. As the adapter 13 moves, the wire harness protective sleeve 171 bends along the sliding direction to reduce the space occupied by the wire harness 21, while preventing multi-directional bending of the wire harness 21, further protecting the wire harness 21 and ensuring that the sliding mechanism 12 is not affected by the wire harness 21 during sliding. For example, the wire harness protective sleeve 171 can be a cable chain or other deformable flexible sleeve.

[0088] In the preferred embodiment, reference Figure 2 The fixed end of the wire harness protective sleeve 171 is fixedly connected to the bracket back plate 162 through the fixed end connector 173.

[0089] In the preferred embodiment, reference Figure 2 The movable end of the wire harness protective sleeve 171 is fixedly connected to the side of the adapter 13 facing the wire harness receiving assembly 17 via the movable end connector 172.

[0090] In some embodiments, reference is made to Figure 2 The bracket 16 is provided with a cable outlet 165, which is located close to the fixed end of the wire harness protective sleeve 171. The wire harness 21 extends out through the opening of the fixed end of the wire harness protective sleeve 171 and is then led out through the cable outlet 165 for external connection.

[0091] Specifically, the cable outlet 165 is located on the side plate 161 of the bracket and / or the base plate 163 of the bracket.

[0092] In some embodiments, the optical path switching device 1 further includes a detection component 18, specifically including a reading head 181, a grating ruler 182 matched with the reading head 181, and a reading head mounting base 183. The reading head 181 is fixedly connected to the adapter 13 through the reading head mounting base 183. The grating ruler 182 is fixedly disposed on the outer wall of the guide body 111. The reading head 181 can move with the adapter 13 to generate relative displacement with the grating ruler 182 to detect the stroke information of the slider assembly 122, thereby obtaining the motion stroke information of the optical path assembly. The grating ruler 182 is disposed on the outer wall of the guide body 111 and cooperates with the reading head 181 fixed on the adapter 13, which not only realizes accurate detection of the stroke, but also makes full use of the internal space of the bracket 16, further improving the integration of the device.

[0093] In the preferred embodiment, reference Figure 2 There is an inner cavity gap between the wire harness receiving assembly 17 and the guide body 111. The side end of the adapter 13 extends out of the guide body 111 and extends toward the inner cavity gap. The reading head 181 is located in the inner cavity gap and is fixedly connected to the side of the adapter 13 facing the bracket back plate 162. The grating ruler 182 is located on the outer side wall of the guide body 111 facing the wire harness receiving assembly 17, thereby effectively utilizing the installation space of the bracket 16 inner cavity.

[0094] In some embodiments, reference is made to Figure 4-6 The optical path switching device 1 also includes a dustproof component 19, covering the connection between the slider assembly 122 and the guide body 111.

The dustproof fixed end 191 is fixedly connected to the slider assembly 122, and the dustproof flexible end 192 is fitted to the guide body 111 to shield the sliding connection between the guide body 111 and the slider assembly 122. This prevents external dirt from entering the slide groove and also prevents impurities or particles that may be generated during sliding from entering the optical equipment, achieving bidirectional protection. In a preferred embodiment, the dustproof component 19 is sheet-shaped.

[0095] In some embodiments, the optical path switching device 1 further includes a transport fixing plate 20, which is detachably and fixedly connected to the adapter 13. This plate restricts the relative movement between the slider assembly 122 and the guide body 111 to fix the slider assembly 122, thereby preventing the slider assembly 122 from being damaged during device transportation.

[0096] Specifically, one end of the transport fixing plate 20 is detachably and fixedly connected to the adapter 13, and the other end of the transport fixing plate 20 is detachably and fixedly connected to the bracket side plate 161 or the outer shell 2 of the optical equipment.

The transport fixing plate 20 is detachably and fixedly connected to the bracket side plate 161 through the first connecting hole and a fastener passing through the first connecting hole. The transport fixing plate 20 is detachably and fixedly connected to the adapter 13 through the second connecting hole 201 and a fastener passing through the second connecting hole 201. The second connecting hole 201 is an oblong hole, which can avoid assembly errors. The transport fixing plate 20 is installed during transportation, and when the optical switching device is working, only the fastener in the first connecting hole can be removed, or the transport fixing plate 20 can be completely disassembled.

[0098] In other embodiments, reference is made to Figure 7 The optical equipment also includes a housing 2, and the optical path switching device 1 also includes a transport fixing plate 20. During the transportation of the device, the transport fixing plate 20 is detachably and fixedly connected to the adapter 13 and the housing 2 respectively, which can limit the relative movement between the slider assembly 122 and the guide body 111, so as to fix the slider assembly 122 and thus prevent the slider assembly 122 from being damaged during the transportation of the device.

[0099] In some embodiments, reference is made to Figure 7 The outer casing 2 is used to house the optical path switching device 1. One end of the transport fixing plate 20 is provided with a first connecting hole, and the other end of the transport fixing plate 20 is provided with a second connecting hole 201. The transport fixing plate 20 is detachably fixedly connected to the outer casing 2 through the first connecting hole and a fastener passing through the first connecting hole. The transport fixing plate 20 is detachably fixedly connected to the adapter 13 through the second connecting hole 201 and a fastener passing through the second connecting hole 201. At least one of the first connecting hole and the second connecting hole 201 is an oblong hole. Thus, the transport fixing plate 20 is fixed to the outer casing 2 through the fasteners and the first connecting hole, and the transport fixing plate 20 is fixed to the adapter 13 through the fasteners and the second connecting hole 201, thereby fixing the slider assembly 122 as a whole. Furthermore, the oblong shape of the second connecting hole 201 helps avoid assembly errors.

[0100] This invention also provides an optical device, including an optical component 3, a housing 2, and a light path switching device 1 as described above. The optical component 3 and the light path switching device 1 are disposed within the housing 2. The optical component 3 can move linearly with the adapter 13 of the light path switching component. The light path switching device 1 is integrated into the optical device as an independent module, providing device applicability and assembly flexibility.

[0101] Understandably, optical component 3 can be any component that requires position switching, such as an optical path mechanism. The optical device can be any device that requires optical path switching, and its light source type can be set based on actual needs, such as, but not limited to, lasers. By setting this optical path switching device 1, it is possible to be compatible with light sources of different wavelengths, power, or other parameters within the entire optical device, reducing the need for adjustments such as spot repositioning caused by light source disassembly and reassembly.
