The mounting plate has a mounting surface, and the mounting surface is provided with a first sliding portion and a first magnetic attractor. The suspension plate has a suspension surface, and the suspension surface is provided with a second sliding portion. The second sliding portion is detachably slidably assembled to the first sliding portion. The suspension portion is also provided with a second magnetic attractor. When the first magnetic attractor and / or the second magnetic attractor are energized, the first magnetic attractor and the second magnetic attractor are magnetically attracted to each other.

[0006] In some embodiments, the first sliding part includes a groove, and the second sliding part is a slide rail that cooperates with the groove, the groove having an inlet for the slide rail to enter.

[0007] In some embodiments, the groove extends through at least one end of the mounting plate to form an entrance for the slide rail to enter.

[0008] In some embodiments, the first sliding part further includes a locking part, which is disposed on the mounting surface and extends toward the slide groove. When the slide rail is embedded in the slide groove, the locking part is used to support the slide rail.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Projection equipment has been widely used in various fields. Currently, some vehicles have begun to install projection equipment as a form of leisure and entertainment during travel. Typically, the projection equipment is fixed to the roof of the vehicle. Among the commonly used methods for fixing projection equipment, the optical engine is usually fixed with screws. The installation accuracy requirements of the optical engine are met through main and auxiliary positioning. The structure has high reliability, but it is not easy to repair, the disassembly process is relatively complex, and the application scenarios are limited.

[0025] Based on this, the inventors of this application propose a quick-release device for an optical engine, an optical engine, and a vehicle to at least partially improve the above-mentioned technical problems. The present invention will be described in detail below with reference to specific embodiments.

[0026] Please refer to the following: Figure 1 and Figure 2 This embodiment provides an optical engine 20, which includes an optical engine body 21 and an optical engine quick-release device 30. The optical engine quick-release device 30 is used to install the optical engine body 21 and can realize the quick installation and removal of the optical engine body 21.

[0027] Specifically, the optical engine body 21 includes a housing 22, and an accommodating space is formed inside the housing 22 for accommodating various components of the optical engine body 21, including but not limited to excitation light sources, lens systems, etc., which will not be described in detail in this embodiment. The optical engine body 21 also includes a projection lens 23, which is disposed in the housing 22 and is used to project image light outward.

[0028] Please continue reading. Figure 2The quick-release device 30 for the optical engine includes a mounting plate 50 and a suspension plate 40. The mounting plate 50 is used for mounting in a fixed area, which is the mounting area of ​​the optical engine 20. For example, in a more specific embodiment, the fixed area may be the roof of a vehicle. The suspension plate 40 is used to connect the optical engine body 21 and is detachably mounted to the mounting plate 50.

[0029] See Figure 3 The mounting plate 50 has a mounting surface 51, which refers to the surface of the mounting plate 50 used for mounting the suspension plate 40. Other surfaces of the mounting plate 50 can be used to fix the mounting plate 50 to the fixed area. In this embodiment, the mounting plate 50 also has a plurality of mounting holes 52, which are formed on the mounting surface 51 and penetrate the mounting plate 50. The mounting holes 52 are suitable for inserting bolts to fix the entire mounting plate 50 to the fixed area. There can be multiple mounting holes 52, which can be evenly distributed on the mounting surface 51. This embodiment does not limit this. In some other embodiments, the mounting plate 50 can also be fixed to the fixed area by other means, such as by adhesive bonding, snap-fitting, etc.

[0030] The mounting surface 51 is provided with a first sliding portion 53, which is used to slidably assemble the suspension plate 40. In this embodiment, the first sliding portion 53 includes a groove 54, which has an inlet 55. There can be one or more grooves 54; this embodiment does not limit this. In this embodiment, there are two grooves 54, which are arranged approximately parallel to each other and spaced apart. This arrangement of two grooves 54 makes the installation of the suspension plate 40 more stable. It is understood that in other embodiments, there can be multiple grooves 54. In this embodiment, "multiple" refers to two or more, and "more than" refers to two or more. Furthermore, in other embodiments, the first sliding portion 53 can also be configured as a slide rail 43, etc., as long as the suspension plate 40 can be slidably assembled onto the mounting plate 50; this embodiment does not limit this.

[0031] Please refer to the following: Figure 4 and Figure 5The suspension plate 40 has a suspension surface 41, which refers to the surface of the suspension plate 40 facing the mounting surface 51 of the mounting plate 50. The suspension surface 41 is provided with a second sliding part 42, which is detachably and slidably assembled to the first sliding part 53. In this embodiment, the second sliding part 42 includes a slide rail 43, which can cooperate with a slide groove 54. An inlet 55 allows the slide rail 43 to enter the slide groove 54. The number of slide rails 43 can match the number of slide grooves 54. In this embodiment, there are two slide rails 43, which are arranged approximately parallel and spaced apart, and each corresponds to one slide groove 54. During assembly, the slide rails 43 can be inserted from the inlet 55 of the slide groove 54. To facilitate the insertion of the slide rails 43, in this embodiment, the slide groove 54 extends through at least one end of the mounting plate 50 to form an inlet 55 for the slide rails 43 to enter. In this implementation, the user only needs to hold the suspension plate 40 and align it with one end of the mounting plate 50 during assembly, ensuring that the slide rail 43 corresponds to the slide groove 54. This provides better visualization during assembly and makes the process more convenient. Specifically, in some embodiments, the slide groove 54 can extend through both ends of the mounting plate 50, forming entrances 55 at both ends for the slide rail 43 to enter. This further facilitates the installation and removal of the suspension plate 40. It is understood that in other embodiments, the second sliding part 42 can also be configured as a slide groove, in which case the first sliding part 53 can be configured as a slide rail. This embodiment does not limit this.

[0032] In this embodiment, to facilitate accurate identification of the installation direction of the hanging plate 40 during installation, a mark 59 is provided on the mounting surface 51. The mark 59 is used to indicate the insertion direction of the inlet 55, so that the user can assemble the hanging plate 40 according to the predetermined insertion direction, saving assembly time. The mark 59 can be text, arrows, or other illustrative symbols, etc., and this embodiment does not limit it.

[0033] To ensure the stability of the slide rail 43 after it is installed in the slide groove 54, in this embodiment, the first sliding part 53 further includes a locking part 60. The locking part 60 is disposed on the mounting surface 51 and extends towards the slide groove 54. When the slide rail 43 is embedded in the slide groove 54, the locking part 60 supports the slide rail 43 and prevents the slide rail 43 from falling off the slide groove 54. In other embodiments, the slide groove 54 can also be configured as a dovetail groove, I-beam groove, etc., which can also serve to support the slide rail 43. Correspondingly, the slide rail 43 can be configured to cooperate with the slide groove 54. In this embodiment, the locking part 60 is only disposed in a part of the slide groove 54. In other embodiments, the locking part 60 can be disposed in the entire area of ​​the slide groove 54 along the extension direction of the slide groove 54.

[0034] Please refer to it again. Figure 3 The mounting surface 51 is further provided with a first magnetic attractor 57. Specifically, the mounting surface 51 has an embedding groove 56, and the first magnetic attractor 57 is embedded in the embedding groove 56. The suspension surface 41 is provided with a second magnetic attractor 44. The first magnetic attractor 57 and the second magnetic attractor 44 can magnetically engage and magnetically attract each other. At least one of the first magnetic attractor 57 and the second magnetic attractor 44 is an electromagnet. When the first magnetic attractor 57 and / or the second magnetic attractor 44 are energized, the first magnetic attractor 57 and the second magnetic attractor 44 magnetically attract each other. This implementation makes the connection between the first magnetic attractor 57 and the second magnetic attractor 44 stronger during the magnetic attraction process, and the installation more stable. Moreover, after the power is turned off, the magnetic attraction state can be quickly disengaged, making disassembly more convenient.

[0035] In this embodiment, when the first magnetic attractor 57 is embedded in the embedding groove 56, it may not protrude beyond the embedding groove 56, meaning the embedding groove 56 retains a certain depth. This allows the second magnetic attractor 44 to partially embed into the embedding groove 56 when the second magnetic attractor 44 magnetically attracts the first magnetic attractor 57, further improving the connection stability between the first magnetic attractor 57 and the second magnetic attractor 44. Of course, in other embodiments, the first magnetic attractor 57 may be approximately flush with the embedding groove 56, for example, the first magnetic attractor 57 may completely fill the embedding groove.

[0036] In this embodiment, the first magnetic attractor 57 can be, for example, a magnet or a metal that can be magnetically attracted, such as iron. The second magnetic attractor 44 can be an electromagnet. In other embodiments, the first magnetic attractor 57 can be an electromagnet, and the second magnetic attractor 44 can be a magnet or a metal that can be magnetically attracted, such as iron.

[0037] During assembly, the user can hold the suspension plate 40 and insert the slide rail 43 into the corresponding slide groove 54. Then, after aligning the first magnetic member 57 and the second magnetic member 44, power is applied to magnetically attract them. To facilitate alignment between the first magnetic member 57 and the second magnetic member 44, in this embodiment, the first magnetic member 57 is disposed in the first sliding portion 53, i.e., the embedding groove 56 is disposed within the slide groove 54, and the first magnetic member 57 is embedded within the embedding groove 56. The second magnetic member 44 is disposed in the second sliding portion 42. The advantage of this implementation is that when the user holds the suspension plate 40 and slides it relative to the mounting plate 50, the first magnetic member 57 and the second magnetic member 44 can align with each other. During this alignment process, the first magnetic member 57 and the second magnetic member 44 will make contact and produce a sound, thus confirming the alignment between them. Then, power can be applied to the second magnetic member 44.

[0038] Please continue reading. Figure 3 To improve the stability of the first magnetic attractor 57 and the second magnetic attractor 44 during the magnetic adsorption process and prevent the equipment from suddenly losing power due to malfunction, which could lead to a loss of magnetic attraction between the first magnetic attractor 57 and the second magnetic attractor 44 and instability between the suspension plate 40 and the mounting plate 50, in this embodiment, the first magnetic attractor 57 is disposed in the area of ​​the first sliding part 53 corresponding to the locking part 60. Thus, even if the first magnetic attractor 57 and the second magnetic attractor 44 lose their magnetic attraction, the locking part 60 can still provide stable load-bearing capacity for the suspension plate 40, preventing damage to the optomechanical body 21. It is understood that in some other embodiments, the first magnetic attractor 57 may also be disposed at other positions on the mounting surface 51; this embodiment does not limit this.

[0039] Furthermore, during installation, to better position the relative positions of the suspension plate 40 and the mounting plate 50, the mounting surface 51 is also provided with a positioning groove 58, and the suspension surface 41 is provided with a positioning post 45. One end of the positioning groove 58 is configured to accommodate the insertion of the positioning post 45, allowing the positioning post 45 to be embedded in the end of the positioning groove 58. If the positioning post 45 fails to embed in the positioning groove 58 during installation, it indicates that the relative positions of the suspension plate 40 and the mounting plate 50 are not aligned, and there may be an offset. Once the suspension plate 40 and the mounting plate 50 are aligned, and the positions of the first magnetic suction member 57 and the second magnetic suction member 44 are aligned one-to-one, the positioning post 45 can then be embedded in the positioning groove 58, achieving precise positioning.

[0040] To further improve the connection stability between the suspension plate 40 and the mounting plate 50, the number of first magnetic accommodating elements 57 can be one or more. In this embodiment, there are multiple first magnetic accommodating elements 57, and these multiple first magnetic accommodating elements 57 are evenly distributed. Correspondingly, the number of second magnetic accommodating elements 44 is the same as the number of first magnetic accommodating elements 57, and they are arranged in a one-to-one correspondence. The multiple second magnetic accommodating elements 44 can be configured to be synchronously energized or de-energized. When the suspension plate 40 needs to be fixed, the multiple second magnetic accommodating elements 44 are synchronously energized and magnetically attracted to the multiple first magnetic accommodating elements 57, resulting in a stronger magnetic attraction and more stable installation. When disassembly is required, the multiple second magnetic accommodating elements 44 are synchronously de-energized and separated from the multiple first magnetic accommodating elements 57, making disassembly more convenient. Specifically, in this embodiment, there are four first magnetic accommodating elements 57, and similarly, there are four second magnetic accommodating elements 44.

[0041] The quick-release optical engine device 30 provided in this embodiment, during installation, after the suspension plate 40 is installed in place, controls the second magnetic chuck 44 to be energized. At this time, an attractive force is generated between the first magnetic chuck 57 and the second magnetic chuck 44. Since the mounting plate 50 is fixed, the suspension plate 40 will move as a whole towards the first magnetic chuck 57 until the first magnetic chuck 57 and the second magnetic chuck 44 are attracted together. In the attracted state, the suspension plate 40 is stable in all directions, and the optical engine body 21 can be stably installed and fixed. When disassembly is required, simply control the second magnetic chuck 44 to be de-energized. The operation is convenient and quick, the structure is simple, and maintenance is also more convenient.

[0042] The optical engine body 21 can be directly connected to the suspension plate 40 and then fixed to the optical engine quick-release device 30, for example, by bolts. In this embodiment, the suspension plate 40 is at least a part of the outer shell 22 of the optical engine body 21, and the suspension surface 41 constitutes part of the outer surface of the optical engine body 21. This is equivalent to the optical engine body 21 being directly suspended on the mounting plate 50, which can further compress the volume of the entire optical engine 20. For example, in this embodiment, the suspension plate 40 is the top shell or part of the top shell of the optical engine 20. Of course, it is understood that in some other embodiments, the suspension plate 40 may also be other parts of the outer shell 22 of the optical engine 20, and this embodiment does not limit this.

[0043] The quick-release device 30 and optical engine 20 provided in this embodiment only require the mounting plate 50 to be installed in a fixed area during installation. The second sliding part 42 of the suspension plate 40 is slidably assembled with the first sliding part 53 of the mounting plate 50, aligning the first magnetic 57 and the second magnetic 44. When the first magnetic 57 and / or the second magnetic 44 are energized, they magnetically attract each other, stably fixing the suspension plate 40 in the fixed area. This magnetic attraction method stably fixes the suspension plate 40 and the optical engine 20 connected to it, ensuring stable installation of the optical engine 20. When disassembly is required, the first magnetic 57 and / or the second magnetic 44 are de-energized, disengaging their magnetic attraction. The suspension plate 40 can then be removed by sliding, achieving disassembly.

[0044] This embodiment also provides a vehicle (not shown) that includes the above-described optical engine 20. The optical engine 20 can be installed inside the vehicle, for example, and the mounting plate 50 can be installed on the roof or ceiling of the vehicle. Of course, in some other embodiments, the optical engine 20 can also be installed in other locations of the vehicle, and this embodiment does not limit this.

[0045] The vehicle provided in this embodiment uses the aforementioned quick-release optical engine device 30 to enable the rapid installation and removal of the optical engine 20, facilitating adjustments to the installation position of the optical engine 20 and maintenance.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model, and should all be included within the protection scope of this utility model.
