Due to the elastic abutment of the elastic part against the fixed part and the elastic force of the limiting rod, the limiting rod can be slightly displaced relative to the fixed part, thereby reducing the internal stress of the fixed base caused by pressure (i.e., the pushing force of the adjusting rod) and reducing the probability of position displacement of the fixed base, which is beneficial to improving the stability of the optical device and extending the service life of the optical device.

[0057] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0058] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be a component centered thereon. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a component centered thereon. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0059] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0060] In existing products, the reflector adjustment device usually locks the fixed base and the fixing part through a threaded rod, and then adjusts the deflection angle of the reflector through the adjusting rod. However, due to the high hardness of the threaded rod, the fixed base and the fixing part are rigidly locked. When the deflection angle of the reflector is adjusted by the adjusting rod, it is easy to cause excessive internal stress in the fixed base fixed with the reflector. When the reflector adjustment device falls, collides, or is vibrated by external force, the internal stress is released, causing the position of the reflector to shift.

[0061] In addition, another reflector adjustment device uses a plurality of elastic members, each of which is respectively arranged on each threaded rod of the reflector adjustment device. This type of reflector adjustment device is difficult to assemble, resulting in high processing costs and material costs.

[0062] Please also read Figure 1 and Figure 2The reflector adjustment device 100 provided in the embodiment of the present disclosure includes a fixed base 1, a limiting rod 3, a fixing member 5, an adjustment assembly 7 and an elastic member 9. One side of the fixed base 1 is used to fix a reflector 2. The limiting rod 3 is arranged on a side of the fixed base 1 away from the reflector 2. The limiting rod 3 includes a connecting portion 31 and a limiting portion 33 connected to the connecting portion 31. One end of the connecting portion 31 away from the limiting portion 33 is connected to the fixed base 1. A limiting hole 51a and at least one adjustment hole 51b are provided on the fixing member 5. The limiting portion 33 of the limiting rod 3 can be movably penetrated in the limiting hole 51a. The fixed base 1 is located on one side of the fixing member 5. The adjustment assembly 7 includes at least one adjustment rod 71, each adjustment rod 71 can be movably inserted into an adjustment hole 51b, and one end of the adjustment rod 71 close to the fixed base 1 is used to abut against the side of the fixed base 1 away from the reflector 2, so that the fixed base 1 deflects relative to the fixed member 5, thereby adjusting the deflection angle of the reflector 2, thereby adjusting the path of the light beam emitted by the reflector 2. When the adjustment rod 71 adjusts the deflection angle of the reflector 2, the adjustment rod 71 abuts against the fixed base 1. The elastic member 9 is sleeved on the limiting portion 33 of the limiting rod 3 and is located on the side of the fixed member 5 away from the fixed base 1, and the two ends of the elastic member 9 elastically abut against the fixed member 5 and one end of the limiting portion 33 away from the connecting portion 31.

[0063] The reflector adjustment device 100 disclosed in the present invention is provided with an elastic member 9 sleeved on the limit rod 3, and the two ends of the elastic member 9 elastically abut against the fixing member 5 and the end of the limit portion 33 away from the connecting portion 31, respectively, and the limit portion 33 of the limit rod 3 can be movably inserted into the limit hole 51a of the fixing member 5, so that the adjustment rod 71 abuts against the fixing base 1 to adjust the deflection of the fixing base 1 relative to the fixing member 5 (such as Figure 4 or Figure 5 As shown in the deflection state, due to the elastic force of the elastic member 9 against the fixing member 5 and the limiting rod 3, the limiting rod 3 can be slightly displaced relative to the fixing member 5 (not shown in the figure), thereby reducing the internal stress of the fixed base 1 caused by the pressure (i.e. the pushing force of the adjusting rod 71), reducing the probability of the fixed base 1 being positionally offset, and being beneficial to improving the stability of the reflector setting adjustment device 100.

[0064] Please also read Figure 2 and Figure 3The fixed base 1 includes a substrate 11 and a boss 12 arranged on one side of the substrate 11, and the other side of the substrate 11 is bonded to the reflector 2, for example, the reflector 2 can be bonded to the substrate 11 by adhesive. The boss 12 includes a through hole 121, and the connecting portion 31 is fixed in the through hole 121. Specifically, the through hole 121 can be processed on the boss 12 by milling, slotting or drilling, and the boss 12 and the through hole 121 can also be integrally formed, which is not limited by the present disclosure. The side of the substrate 11 close to the fixing member 5 is a polygon, and each adjustment rod 71 is respectively against an inner corner of the polygon. In this embodiment, the adjustment component 7 includes four adjustment rods 71, and the side of the substrate 11 close to the fixing member 5 is a rectangle. In other embodiments, the side of the substrate 11 close to the fixing member 5 can be circular or other polygons, and each adjustment rod 71 can be respectively against other positions of the fixed base 1 except the inner corner, which is not limited by the present disclosure.

[0065] The limiting portion 33 of the limiting rod 3 includes a sleeve portion 331 connected to the connecting portion 31 and a limiting end 333 connected to the sleeve portion 331 away from one end of the connecting portion 31, and the radial dimension of the limiting end 333 is larger than the radial dimension of the sleeve portion 331 and larger than the aperture of the limiting hole 51a, so as to prevent the limiting rod 3 from escaping from the limiting hole 51a. The sleeve portion 331 of the limiting portion 33 can be movably inserted into the limiting hole 51a. One end of the elastic member 9 elastically abuts against the fixing member 5, and the other end abuts against the limiting end 333 of the limiting portion 33. In this embodiment, the limiting rod 3 is a round head step screw, and the connecting portion 31 is provided with a thread, and the connecting portion 31 is screwed to the fixing base 1. Since the connection part 31 needs to be fixed in the through hole 121, a matching thread can be processed at the notch 121a of the through hole 121 by any one of turning, milling, tapping, threading, grinding, lapping and whirlwind cutting. When the connection part 31 is fixed in the through hole 121, the thread of the connection part 31 matches the thread of the through hole 121. In other embodiments, the limiting rod 3 can be any one of a plastic column, a stainless steel step screw, a non-standard step screw, a hexagonal step screw, an external hexagonal step screw, a stainless steel hexagonal step screw and a cross pan head step screw, which is not limited by the present disclosure. Please refer to Figure 6 For example, when the limiting rod 3 is a plastic column, the connecting portion 31 of the limiting rod 3 can be movably inserted into the limiting hole 51a, the sleeve portion 331 of the limiting portion 33 abuts against the limiting hole 51a of the fixing member 5, and the connecting portion 31 of the limiting rod 3 is accommodated in the space formed by the through hole 121 and the reflector 2, thereby fixing the fixing base 1 and the fixing member 5.

[0066] Please refer to Figure 2In this embodiment, the fixing member 5 is roughly in the shape of a rectangular plate, and the limiting hole 51a is set at the intersection of the diagonals of the fixing member 5. The fixing member 5 is provided with four adjustment holes 51b, and each adjustment hole 51b is set at a position relatively far from the limiting hole 51a on the fixing member 5, that is, the four adjustment holes 51b are respectively set at the four vertices of the fixing member 5, so that each adjustment rod 71 passes through the corresponding adjustment hole 51b and abuts against an inner corner of the fixing base 1. In other embodiments, the center through hole 51a and the adjustment hole 51b can be set at any position of the fixing member 5, for example, the limiting hole 51a can be set at the center of gravity or edge position of the fixing member 5, and the present disclosure does not limit it. It should be noted that when the limiting hole 51a is set at the intersection of the diagonals of the fixing member 5, the limiting rod 3 can fix the fixing base 1 to the fixing member 5 more stably.

[0067] The fixing member 5 is also provided with one or more bonding holes 53, and the bonding holes 53 are used to accommodate adhesive 531, and the adhesive 531 is used to bond the fixing member 5 and the fixing base 1. In the present embodiment, the fixing member 5 is provided with two bonding holes 53, and the bonding holes 53 are symmetrically arranged on both sides of the limiting hole 51a corresponding to the limiting rod 3. In other embodiments, the fixing member 5 may also be provided with one or three bonding holes 53, and the bonding holes 53 may be arranged at any position of the fixing member 5, which is specifically determined according to the needs of the user and is not limited by the present disclosure. After the fixing base 1 and the fixing member 5 are connected through the limiting rod 3, when the adjustment component 7 has adjusted the deflection angle of the reflector 2, the adhesive 531 is injected into the bonding hole 53 by a dispensing device or manually, so that the relative position of the fixing base 1 and the fixing member 5 can be further fixed, which is conducive to enhancing the stability of the reflector adjustment device 100. The adhesive 531 may be an organic adhesive, an inorganic adhesive or a mixture of an inorganic adhesive and an organic adhesive, such as polyvinyl alcohol, urea-formaldehyde resin, phenol-formaldehyde resin, silicate, phosphate, sulfate, polyvinyl acetate or polyvinyl alcohol.

[0068] The adjusting rod 71 is any one of a bolt and a plastic column. Figure 4In this embodiment, the adjusting rod 71 is a bolt. When the adjusting rod 71 is a bolt, the adjusting hole 51b corresponding to the position of the adjusting rod 71 on the fixing member 5 is processed into a corresponding thread by any one of turning, milling, tapping, threading, grinding, lapping and whirlwind cutting. By rotating the adjusting rod 71 relative to the fixing member 5, the adjusting rod 71 can be moved relative to the fixing member 5 at the same time, and the end 71a of the adjusting rod 71 close to the substrate 11 applies a pushing force to the substrate 11 of the fixing base 1, so that the fixing base 1 is deflected relative to the fixing member 5, thereby realizing the adjustment of the angle between the light incident on the reflector 2 and the light reflected from the reflector 2. When each adjustment hole 51b is arranged at a position relatively far from the limiting hole 51a on the fixing member 5, the adjusting rod 71 can adjust the deflection angle of the reflector 2 more conveniently and quickly. The deflection angle of the reflector 2 can be adjusted by using 1-3 adjustment rods 71, which is beneficial to reduce the number of adjustment rods 71, thereby reducing production costs.

[0069] Please also read Figure 5 and Figure 6 , each adjusting rod 71 also includes a fixing portion 711, and the fixing portion 711 is arranged at one end of the adjusting rod 71 away from the fixed base 1. When the adjusting assembly 7 has adjusted the deflection angle of the reflector 2, the fixing portion 711 is used to fix the position of the adjusting rod 71. In this embodiment, the fixing portion 711 is an adhesive, and the adhesive is used to fix the position of the adjusting rod 71. The adhesive is set on the adjusting rod 71 by a dispensing device or manually. Among them, the adhesive can be an organic adhesive, an inorganic adhesive or a mixture of an inorganic adhesive and an organic adhesive, such as polyvinyl alcohol, urea-formaldehyde resin, phenolic resin, silicate, phosphate, sulfate, polyvinyl acetate or polyvinyl alcohol. In other embodiments, the fixing portion 711 can also be other structures that can fix the relative position between the adjusting rod 71 and the fixing member 5, such as solder, buckle, cover, etc., and the present disclosure does not limit this.

[0070] The elastic member 9 is any one of a compression spring, a spring, a silicone sleeve and a foamed elastic body. In the present embodiment, the elastic member 9 is a compression spring, and one end of the compression spring away from the fixing member 5 is fixed to the end of the limiting rod 3 away from the fixing member 5, and the elastic member 9 elastically acts on the fixing member 5 and the end of the limiting portion 33 away from the connecting portion 31. When the elastic member 9 is a silicone sleeve (not shown), the silicone sleeve is sleeved on the limiting rod 3. Due to the strong elasticity of silicone, the two ends of the elastic member 9 elastically support the fixing member 5 and the end of the limiting portion 33 away from the connecting portion 31. It can be understood that the elastic member 9 is not limited to the above types.

[0071] Please also refer to Figure 4 and Figure 5The adjustment process of the deflection angle of the reflector 2 by the adjustment component 7 of the reflector adjustment device 100 is as follows: when the deflection angle of the reflector 2 needs to be changed by the adjustment component 7, the adjustment rod 71 is rotated relative to the fixing member 5, and the adjustment rod 71 can be moved relative to the fixing member 5 at the same time, and the end 71a of the adjustment rod 71 close to the substrate 11 applies a pushing force to the substrate 11 of the fixed base 1, so that the fixed base 1 is deflected relative to the fixing member 5. By rotating the adjustment rods 71 ​​at different positions of the adjustment component 7, the corresponding positions of the fixed base 1 can be reversely deflected relative to the fixing member 5, thereby changing the deflection angle of the reflector 2, and then adjusting the angle between the light incident on the reflector 2 and the light reflected from the reflector 2. When the adjustment component 7 of the reflector adjustment device 100 has completed adjusting the deflection angle of the reflector 2, the adhesive 531 is injected into the adhesive hole 53 by a dispensing device or manually, and then the fixing part 711 is set on the adjustment rod 71. For example, the fixing part 711 can be adhesive, solder, clip, cover, etc., so as to further fix the relative position of the fixed base 1 and the fixing part 5, which is beneficial to enhance the stability of the reflector adjustment device 100.

[0072] The present disclosure also provides an optical device. Figure 1 and Figure 7 The optical device 200 of the embodiment of the present disclosure includes a reflector 2 and the reflector adjustment device 100 described in any of the above embodiments. The reflector 2 is fixed to one side of the fixed base 1, and the reflector 2 is used to reflect the incident light. The optical device 200 also includes a light source module 201a and a shell 201b. The fixing member 5 is mechanically connected to the shell 201b or is integrally formed with the shell 201b. Among them, the light source module 201a is used to emit image light (not shown). The reflector 2 is used to reflect image light. The light emitted by the light source module 201a is emitted after being reflected by the reflector 2; by rotating the adjustment rod 71 of the adjustment component 7, the adjustment rod 71 can be rotated relative to the fixing member 5 and can be moved relative to the fixing member 5 at the same time, so that the fixed base 1 is deflected relative to the fixing member 5, thereby realizing the adjustment of the angle between the optical axis of the image light incident on the reflector 2 and the optical axis of the reflected light.

[0073] The optical device 200 can be any one of a projection device, a near-eye display device, a head-up display device, and a distance measuring device. The composition of the optical device 200 is determined according to the specific use requirements, and the present disclosure does not limit it. For example, when the optical device 200 is a projection device, the optical device 200 also includes a zoom module (not shown), a modulation module, and a lens module; wherein the light source module 201a is used to emit image light, and the zoom module is used to zoom the image light and emit it, and is used to change the zoom multiple of the image light. The reflector 2 is used to receive and guide the image light emitted by the zoom module. The modulation module is used to receive the image light and modulate the image light into modulated light. The lens module is used to receive the modulated light and project the modulated light. The optical device 200 can also be a head-up display device. When the optical device 200 is a head-up display device, the optical device also includes an image generating unit (not shown), the reflector 2 may be a free-form surface reflector, the image generating unit is used to emit image light, the reflector 2 is fixed to one side of the reflector adjustment device 100, and the reflector 2 is used to project the image light onto the side of the vehicle windshield away from the human eye.

[0074] The optical device 200 disclosed in the present invention can relatively stably fix the reflector 2 on the housing 201b of the optical device 200 by setting the reflector adjustment device 100 described in any of the above embodiments; when the deflection angle of the reflector 2 is adjusted, the adjusting rod 71 abuts against the fixed base 1 and the deflection of the fixed base 1 relative to the fixing member 5 is adjusted. Due to the elastic abutment of the elastic member 9 against the fixing member 5 and the elastic force of the limiting rod 3, the limiting rod 3 can be slightly displaced relative to the fixing member 5, thereby reducing the internal stress of the fixed base 1 caused by the pressure (i.e., the pushing force of the adjusting rod 71), reducing the probability of the fixed base 1 being shifted in position, which is beneficial to improving the stability of the optical device 200 and extending the service life of the optical device 200.

[0075] The above descriptions are merely embodiments of the present disclosure and are not intended to limit the patent scope of the present disclosure. Any equivalent structure or equivalent process transformation made using the contents of the present disclosure specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present disclosure.
