Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted equipment, and in particular to a fixing part, a HUD device, a HUD system and a mobile terminal. Background Art

[0002] With the continuous development of vehicle technology, there are a large number of solutions for vehicle architecture design and vehicle intelligent design, and the iteration and update cycle is getting shorter and shorter. On the one hand, various car companies are constantly designing and launching new models and architectures. On the other hand, users have higher and higher requirements for the convenience, intelligence and safety of vehicle use, which makes car companies continue to add new vehicle-mounted equipment to improve user experience. The installation compatibility of vehicle-mounted equipment with different models has gradually become a hot issue in the vehicle assembly process.

[0003] For example, head-up display (HUD) has been widely used in vehicles. The HUD device projects the vehicle's instrument information (such as speed, rotation speed, temperature, fuel level, etc.) and navigation information to the front of the driver's field of vision. The driver can see the vehicle's instrument information and navigation information in front of the field of vision without having to look down at the instrument panel or central control display under the steering wheel. This not only improves driving comfort, but also improves the braking reaction time in emergency situations and improves driving safety.

[0004] However, driving assistance devices such as HUD are generally highly integrated with the layout and frame structure of the entire vehicle. Therefore, the HUD shell usually adopts a highly customized shell. Since different car companies and different models have different installation requirements for HUD, if each car company and each model deeply customizes a HUD shell, the HUD shell will have different shapes. Not only that, different models have different requirements for the HUD assembly position, and HUD manufacturers need to repeatedly design and open the mold for the HUD shell, which has poor adaptability. Summary of the invention

[0005] The present application provides a fixing part, a HUD device, a HUD system and a mobile terminal, which can realize the sharing of the HUD shell by different mobile terminal (such as vehicle) models, thereby improving the adaptability of the HUD.

[0006] In a first aspect, the present application provides a fixing member, the fixing member comprising a first fixing portion and a second fixing portion, wherein the first fixing portion is used for fixing and assembling with a HUD housing, and the second fixing portion is used for fixing and assembling with a frame of a first mobile terminal.

[0007] In this way, a fixed connection between the HUD housing and the frame of the first mobile terminal can be achieved through the fixing member.

[0008] The fixing provided in the present application can fix the HUD shell to the frame of the mobile terminal. Since the two fixing parts of the fixing are respectively fixedly assembled with the HUD shell and the frame, they can play the role of transfer installation. In particular, when the installation part designed on the HUD shell does not match the installation part of the frame, the transfer of the fixing plays the role of bridging the HUD shell and the frame. When the HUD device needs to be installed on mobile terminals of different models, there is no need to repeatedly design and open the mold for the HUD shell. In this way, multiple mobile terminals can install the same HUD device, so that the shell of the HUD device forms a unified platform version, which improves the adaptability of the HUD device and shortens the development cycle. Moreover, through the transfer of the fixing 10, the HUD device can be installed in the mobile terminal in a variety of possible postures, meeting the installation requirements of different models of mobile terminals for the HUD device, and further improving the adaptability of the HUD device.

[0009] In addition, the fixing part provided by the present application is an independent component, and its structure is simpler than that of the HUD shell. It does not need to consider coupling with multiple devices (such as considering the placement between internal optical systems) like designing the HUD shell. It has a short production cycle, low manufacturing cost and flexible design. When the HUD needs to be installed in a new model of mobile terminal, a movable fixing part adapted to the model can be quickly designed and manufactured to install the HUD device in the new model of mobile terminal, which helps to shorten the design and assembly cycle of the mobile terminal.

[0010] Furthermore, the first fixing part and the second fixing part are connected in one piece. In this case, the fixing part can be an integrally formed device, and the HUD is relatively stable when installed by the fixing part, and has almost the same stability as the HUD housing is directly installed in the mobile terminal.

[0011] In a possible implementation manner of the first aspect, the first fixing portion and the second fixing portion are located in different planes.

[0012] In some solutions, the shapes of the vehicle frames are different, and the space formed by the vehicle frames to accommodate the HUD device is usually different in size and shape. In the above embodiment, the HUD housing can be installed in the vehicle frame in various shapes and postures through the plane difference between the first fixing portion and the second fixing portion, so that the installation of the HUD device can flexibly adapt to the spatial structure in the vehicle frame, thereby improving the adaptability of the HUD device.

[0013] In a possible implementation of the first aspect, there is a first receiving space between the first fixing portion and the second fixing portion. In some solutions, components have been installed in the space originally required for the HUD housing before installing the HUD device on the vehicle, or there may be a need to install other components after assembling the HUD device. At this time, through the above implementation, a spatial misalignment exists between the first fixing portion and the second fixing portion, and a receiving space, that is, the first receiving space, can be reserved in the vehicle frame. This first receiving space can be used to accommodate other components, or this receiving space can also accommodate the HUD device so that the HUD housing can form a certain misaligned posture, thereby accommodating the components of the vehicle in the remaining space formed by the misalignment.

[0014] In another possible implementation of the first aspect, the fixing member includes a top plate, a bottom plate, and a side plate. The top plate and the bottom plate are connected by the side plate. The first fixing portion is disposed on the top plate, and the second fixing portion is disposed on the bottom plate. Among them, the side plate is provided with an opening to form a first receiving space that can pass through the side plate between the top plate and the bottom plate.

[0015] Exemplarily, in some solutions, the side cross-section of the fixing member can be in various structures such as a "Z" - shaped structure, an "I" - shaped structure, a "匚" - shaped structure, etc. It can not only form a receiving space between the top plate and the bottom plate, but also set an opening on the side plate so that components can pass through the side plate of the fixing member. Further, the HUD housing is installed in the vehicle frame in various shapes and poses, and adapts to the space structure in the vehicle frame, improving the adaptability of the HUD.

[0016] In another possible implementation of the first aspect, the HUD housing includes a third fixing portion, and the first fixing portion is matched with the third fixing portion. The vehicle frame of the first movable terminal includes a fourth fixing portion, and the second fixing portion is matched with the fourth fixing portion. The third fixing portion and the fourth fixing portion are not matched.

[0017] It can be seen that a third fixing portion is provided on the HUD housing, and this third fixing portion is not matched with the fourth fixing portion on the vehicle frame. However, through the fixing member, the third fixing portion and the fourth fixing portion can be respectively matched with the first fixing portion and the second fixing portion, achieving the effect of转接 installation and improving the adaptability of the installation of the HUD device.

[0018] In another possible implementation of the first aspect, the fixing member includes a first positioning structure. Further, the HUD housing is also provided with a first positioning portion, and the first positioning portion corresponds to the first positioning structure in the fixing member.

[0019] For example, the first positioning structure may be a positioning hole, and the first positioning portion may be a positioning pin. When the positioning pin is inserted into the positioning structure in the fixing member, the first fixing portion of the first fixing member may be aligned with the third fixing portion in the HUD shell, thereby improving the installation efficiency of the fixing member.

[0020] For another example, the first positioning structure is a positioning pin, and the first positioning portion can be a positioning hole. When the positioning pin is inserted into the positioning hole of the HUD shell, the first fixing portion of the first fixing member can be aligned with the third fixing portion in the HUD shell, thereby improving the installation efficiency of the fixing member.

[0021] In another possible implementation of the first aspect, the fixing member includes a second positioning structure. Further, the frame of the mobile terminal is also provided with a second positioning portion, and the second positioning portion corresponds to the second positioning structure in the fixing member.

[0022] For example, the second positioning structure may be a positioning hole, and the second positioning portion may be a positioning pin. When the positioning pin is inserted into the positioning structure in the fixing member, the second fixing portion of the first fixing member may be aligned with the fourth fixing portion in the frame, thereby improving the installation efficiency of the fixing member.

[0023] For another example, the second positioning structure is a positioning pin, and the second positioning portion can be a positioning hole. When the positioning pin is inserted into the positioning hole set on the frame, the second fixing portion of the first fixing member can be aligned with the fourth fixing portion in the frame, thereby improving the installation efficiency of the fixing member.

[0024] In another possible implementation of the first aspect, the first fixing portion is provided with a first connecting hole, the third fixing portion on the HUD shell is provided with a third connecting hole, and the first fastener is passed through the first connecting hole and the third connecting hole.

[0025] In another possible implementation of the first aspect, the second fixing portion is provided with a second connecting hole, the fourth fixing portion of the frame of the first movable terminal is provided with a fourth connecting hole, and the second fastener is passed through the second connecting hole and the fourth connecting hole.

[0026] In yet another possible implementation manner of the first aspect, the fixing member further includes a fifth fixing portion, and the fifth fixing portion is used to be fixedly assembled with a frame of a second movable terminal, and the second movable terminal is different from the first movable terminal.

[0027] In the above embodiment, multiple groups of fixing parts can be set on the fixing part, and the multiple groups of fixing parts can be adapted to various types of mobile terminals, so that the installation requirements of various types of mobile terminals for HUD can be met through the design of one fixing part, thereby improving the adaptability of the fixing part.

[0028] In another possible implementation of the first aspect, the fixing member is further provided with a third connection hole, and the third connection hole is used to install components of the mobile terminal. Since the space in the mobile terminal is limited, the fixing member can also play a role in installing other components in some solutions, which can not only improve the stability of the installation of components in the mobile terminal, but also help reduce the number of parts in the mobile terminal.

[0029] In yet another possible implementation of the first aspect, one or more weight-reducing holes or weight-reducing cavities may be provided on the fixing member to reduce the mass of the fixing member, thereby contributing to a lightweight design of the mobile terminal.

[0030] In a second aspect, the present application further provides a HUD device, the HUD device comprising a HUD housing and a fixing member described in any one of the first aspects.

[0031] The HUD shell includes a third fixing portion, and the third fixing portion is used to be fixedly connected to the first fixing portion in the fixing member.

[0032] In a possible implementation of the second aspect, the HUD device includes a plurality of fixing components, and the plurality of fixing components are respectively arranged on different sides of the HUD housing.

[0033] Optionally, when the HUD device includes multiple fixing parts, the structures and shapes of the multiple fixing parts may be different, or the same.

[0034] In another possible implementation of the second aspect, the HUD shell is further provided with a first positioning portion, and the first positioning portion corresponds to the first positioning structure in the fixing component.

[0035] In another possible implementation of the second aspect, the HUD housing further includes a sixth fixing portion. The sixth fixing portion is used for fixing and assembling the frame of the first mobile terminal.

[0036] In some solutions, the HUD shell may include multiple sets of fixing parts, some of which can match some of the fixing parts on the frame, while another part of the fixing parts on the HUD shell cannot match another part of the fixing parts on the vehicle. In this case, some of the fixing parts on the HUD shell that match the frame can be directly fixed and installed with the fixing parts on the frame, while the unmatched fixing parts are transferred and installed through fixing parts. In other words, the use of fixing parts can be flexibly set according to actual needs to meet the actual needs of HUD installation.

[0037] In a third aspect, the present application further provides a HUD system, the HUD system comprising: a HUD optical system, and a fixing member as claimed in any one of the first aspect and / or a HUD device as described in any one of the second aspect.

[0038] In a fourth aspect, the present application also provides a mobile terminal, which includes a fixed frame (such as a vehicle frame), and the mobile terminal also includes a fixing member described in any one of the first aspect, or includes a HUD device described in any one of the second aspect of the claim, or includes a HUD system in the third aspect.

[0039] In a possible implementation manner of the fourth aspect, the fixing frame includes a fourth fixing portion, and the fourth fixing portion is used to be fixedly connected to the second fixing portion in the fixing member.

[0040] In yet another possible implementation of the fourth aspect, the fixing frame includes a second positioning portion, and the second positioning portion corresponds to the second positioning structure in the fixing member.

[0042] In another possible implementation of the fourth aspect, the mobile terminal includes a second receiving space, where the second receiving space is used to receive the HUD device.

[0043] The mobile terminal further includes components, which are located in the second receiving space.

[0044] The fixing member is also used to form a first receiving space between the housing of the HUD device and the frame of the mobile terminal to accommodate components in the mobile terminal. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] As users' requirements for the convenience, intelligence and safety of vehicle use become higher and higher, car companies are constantly adding new in-vehicle equipment to improve the user experience. For example, in-vehicle equipment includes but is not limited to projection devices, in-vehicle refrigerators, audio devices, ambient light devices, electronic instrument panels, central control large screens, etc. Among them, projection devices include head up display systems (HUD), light field screens and other devices. These in-vehicle devices enable the intelligence and entertainment of vehicles, greatly improving the user experience.

[0058] Let's take the projection device as an example. Figures 1A to 1C Some application scenarios of vehicle-mounted equipment are exemplified.

[0059] See also Figures 1A to 1C , Figure 1A A schematic diagram of an application scenario of a projection device 100 provided in an embodiment of the present application in the automotive field is shown. Figure 1B A schematic diagram showing another perspective of an application scenario of a projection device 100 provided by an embodiment of the present application in the automotive field, Figure 1C FIG. 1 shows an imaging schematic diagram of a projection device 100 provided in an embodiment of the present application projecting an image into the driver's eyes in the automotive field, which shows Figure 1A and Figure 1B The projection device 100 projects the image into the driver's eyes so that the driver can see the virtual image information.

[0060] Depend on Figures 1A to 1CIt can be seen that when the driver looks out of the car through the windshield 200, he can see a virtual image with a certain depth of field (i.e., the distance of the clear image presented in the range before and after the image focus). Among them, the information in front of the car is obtained through information acquisition modules such as cameras and infrared sensors. The road information in front includes the distance between the front vehicle and the speed of the front vehicle, and the road information, etc., and the corresponding digital information is projected in an imaging manner and closely combined with the environmental information of the front vehicle, wherein the digital information includes but is not limited to: vehicle speed, navigation information (road instructions), vehicle gear, cruise control, distance between the front vehicle and the front vehicle, speed information, power information, cruising range information, audio and video entertainment system information, etc., so that the driver can understand the information needed to drive the vehicle without shifting his sight when driving the vehicle. Avoid driving risks caused by the driver not being able to take into account the road conditions when driving the vehicle, such as looking down at the dashboard or the central control screen information.

[0061] To achieve the above projection, the car needs to have a head up display (HUD), wherein the head up display system may include a projection device 100 and an optical element, wherein the projection device 100 includes an optical system that can project an image, for example, the optical system includes an image generating unit, an image reflecting unit, an image magnifying unit, etc. The optical element may include a windshield 200 of the vehicle, or a reflective film attached to the windshield 200, or a screen separately arranged in the car cabin. The optical element may reflect and / or refract the image projected by the projection device 100 and then project it into the driver's eyes, so that the driver can obtain a virtual information image in front of the windshield 200.

[0062] As mentioned in the background technology section, the shell of vehicle-mounted equipment usually adopts a highly customized shell. However, due to the differences in the installation requirements of vehicle-mounted equipment by different car companies and different models, the shells of vehicle-mounted equipment have different shapes. Taking the HUD device as an example, different models have different requirements for the assembly position of the HUD device. HUD manufacturers need to repeatedly design and open the mold for the HUD shell, which has poor adaptability.

[0063] In view of this, the present application provides a fixing part, a HUD device, a HUD system and a mobile terminal, which can realize the sharing of the HUD shell by different mobile terminal (such as vehicle) models, thereby improving the adaptability of the HUD. It should be understood that the present application embodiment is introduced by taking the HUD device as an example, and the present application is also applicable to the case where the fixing part is used to install the shell of other vehicle-mounted equipment.

[0064] The fixing part, HUD device, HUD system and mobile terminal provided in the present application will be described below with reference to the accompanying drawings.

[0065] See also Figure 2 , Figure 21 is a schematic diagram of a structure of a fixing member provided in an embodiment of the present application. The fixing member 10 includes a first fixing portion 101 and a second fixing portion 102. The first fixing portion 101 is used for fixing and assembling with the HUD housing, and the second fixing portion 102 is used for fixing and assembling with the frame of the first mobile terminal.

[0066] The first fixing part may include a connection structure, such as a connection hole (such as a through hole, a blind hole, etc.), a snap structure, etc., so that it can be fixedly connected to the HUD shell. Similarly, the second fixing part also includes a connection hole, a snap structure, etc., so that it can be fixedly connected to the frame. The frame refers to a fixed frame in a mobile terminal, such as a dashboard beam, a cockpit mounting bracket, a body bracket, a seat bracket, etc.

[0067] like Figure 3 The HUD housing 20 may include a third fixing portion 201, the first fixing portion 101 may match the third fixing portion 201, and the two may be assembled together to realize the fixed connection between the HUD housing 20 and the fixing member 10. Similarly, the vehicle frame 30 may include a fourth fixing portion 301, the first fixing portion 101 may match the fourth fixing portion 301, and the two may be assembled together to realize the fixed connection between the vehicle frame 30 and the fixing member 10.

[0068] As an example of an assembly method of a fixing member 10 and a HUD housing 20, Figure 3 The first fixing portion 101 may include a first connection hole, and the third fixing portion 201 on the HUD housing 20 is provided with a third connection hole. During assembly, the first fastener is passed through the first connection hole and the third connection hole, thereby achieving fixed assembly of the fixing member 10 and the HUD housing 20 (described below). The number of the first connection hole and the second connection hole may be one or more, and their positions may also have multiple possible designs.

[0069] As an example of an assembly method of a fixing member 10 and a frame 30, Figure 3 The second fixing portion 102 may include a second connection hole, and the fourth fixing portion 301 on the frame 30 is provided with a fourth connection hole. During assembly, the first fastener is passed through the second connection hole and the fourth connection hole, thereby achieving fixed assembly of the fixing member 10 and the frame 30. The number of the second connection hole and the fourth connection hole may be one or more, and their positions may also have multiple possible designs.

[0070] Optionally, the above-mentioned fasteners include but are not limited to screw threads, pins, etc., and the embodiments of the present application are not limited to this.

[0071] Combination Figure 2 and Figure 3The two fixing parts of the fixing part 10 are respectively fixedly assembled with the HUD shell 20 and the frame 30, which can play the role of transfer installation. Especially when the installation part designed on the HUD shell 20 (such as the third fixing part 201) does not match the installation part of the frame 30 (such as the fourth fixing part 301), the fixing part 10 is transferred to bridge the HUD shell 20 and the frame 30. In this way, when the HUD device needs to be installed on different models of mobile terminals, there is no need to repeatedly design and open the mold of the HUD shell 20, so that multiple mobile terminals can install the same HUD device, so that the HUD shell 20 can form a unified platform version, shortening the development cycle.

[0072] In some solutions, the positional relationship between the first fixing portion 101 and the second fixing portion 102 can be designed in a variety of possible ways. In this case, the HUD device can be installed in the mobile terminal in a variety of possible postures through the switching of the fixing member 10, so as to meet the installation requirements of different types of mobile terminals for the HUD and improve the adaptability of the HUD. For example, by the relative misalignment of the first fixing portion and the second fixing portion, the position of the HUD can be raised, lowered, or tilted in the accommodation center formed by the frame.

[0073] In addition, the fixing member provided by the present application has a relatively simple structure, a short production cycle, low manufacturing cost and flexible design. When the HUD needs to be installed on a new type of mobile terminal, a movable fixing member adapted to the new type can be quickly designed and manufactured to install the HUD, which helps to shorten the design and assembly cycle of the mobile terminal.

[0074] As a possible implementation, the first fixing portion 101 and the second fixing portion 102 are separately arranged on different parts of the fixing member. For example, the fixing member 10 may include a first part and a second part, which are separately arranged and connected by a connecting device such as a screw or a buckle. The first fixing portion 101 is arranged on the first part, and the second fixing portion 102 is arranged on the second part.

[0075] As another possible implementation, the first fixing part 101 and the second fixing part 102 are integrally connected. In other words, the fixing member 10 is a device formed by one-piece molding, and no connecting structures such as screws and buckles are required to connect the first fixing part 101 and the second fixing part 102 in the middle. On the one hand, by adopting an integrated design for the fixing member 10, only one mold opening is required during the production process, which can shorten the design and production cycle of the fixing member 10. On the other hand, compared with separately arranging the first fixing part 101 and the second fixing part 102 on different components in the fixing member, the integrated design can make the connection between the first fixing part 101 and the second fixing part 102 firm and not easily loose. In this way, by using the fixing member 10 to transfer and install the HUD, the installation of the HUD can be made more stable, almost as stable as directly installing the HUD housing in the vehicle.

[0076] In some scenarios, the fixing member 10 can also be referred to as an ear or an adapter, etc. It should be understood that the names of the devices in this application are only examples, and in different implementation scenarios, the names of the devices can be replaced arbitrarily.

[0077] Continue to combine with Figures 2 to 7 below to introduce the possible designs of the fixing member 10. It should be understood that the following designs and the optional situations exemplified in the designs can be combined.

[0078] In some possible designs, the first fixing part and the second fixing part are located in different planes. Please refer to Figure 2 , where the first fixing part and the second fixing part are misaligned, so that the position of the HUD housing can be lifted or lowered, and the HUD device can be installed in the vehicle frame in various shapes and poses, and can adapt to the spatial structure in the vehicle frame, improving the adaptability of the HUD.

[0079] For ease of understanding, several possible styling designs of the fixing member are示例性 introduced below.

[0080] Example 1, please refer to Figure 4 , Figure 4 is a schematic structural diagram of another fixing member provided by an embodiment of the present application. In Figure 4 , the fixing member includes a top plate, a bottom plate and a side plate 103. The top plate and the bottom plate are connected by the side plate 103 to form a "C" - shaped structure. Among them, the first fixing part 101 is located on the top plate, and the second fixing part 102 is located on the bottom plate. The plane difference between the top plate and the bottom plate can lift the position of the HUD device.

[0081] In some solutions, by lifting the position, the accommodating space that can be vacated can be adapted to various possible structures in the vehicle. Combine with Figure 4, there is a first accommodation space between the first fixing part 101 and the second fixing part 102. At this time, some components in the mobile terminal can be installed in these new accommodation spaces.

[0082] Furthermore, the side plate 103 is provided with an opening, and some components inside the vehicle can also be arranged through the side plate. Exemplarily, please refer to Figure 5 , the side plate 103 is provided with an opening to form a first accommodation space 40 that can pass through the side plate 103 between the top plate and the bottom plate, so that the components 302 inside the vehicle can be arranged through the side plate 103 of the fixing member 10.

[0083] Of course, the structure here is only an example. In some solutions, the side cross-section of the fixing member can be a "Z" - shaped structure, an "I" - shaped structure, an "匚" - shaped structure, and many other structures.

[0084] Example 2, please refer to Figure 6 , Figure 6 is a schematic structural diagram of another fixing member provided by an embodiment of the present application. Figure 6 The part (A) in Figure 6 and the part (B) in Figure 6 show the structure of the fixing member 10 from different perspectives. As

[0085] Furthermore, the plane where the second fixing part 102 is located forms a certain angle with the plane where the first fixing part 101 is located. In this way, an installation space (such as the first accommodation space) can be formed between the second fixing part 102 and the first fixing part 101. This space can be used to adjust the position and pose of the HUD, and can also be used to accommodate the components of the mobile terminal.

[0086] Consider a possible situation. If the installation posture of the HUD housing and the vehicle frame is the first posture when the fixing member 10 is not set, when the HUD housing is installed through the fixing member 10, since the plane where the second fixing part 102 is located forms a certain angle with the plane where the first fixing part 101 is located, it can be regarded as the HUD housing tilting by a certain angle, forming a new installation posture different from the first posture, which can meet the installation requirements of the HUD for different models of mobile terminals.

[0087] Example 3, please refer to Figure 7 , Figure 7 It is a structural schematic diagram of another fixing member provided in an embodiment of the present application. The first fixing portion 101 includes a first connecting hole, such as a connecting hole 1011e, a connecting hole 1011f, a connecting hole 1011g and a connecting hole 1011h, and the first connecting hole is used to fix and assemble with the HUD shell. The second fixing portion 102 includes a second connecting hole, such as a connecting hole 1021c and a connecting hole 1021d, and the second connecting hole is used to fix with the frame. Through the position difference between the first fixing portion 101 and the second fixing portion 102, it can be seen that the fixing member plays a role of transfer installation, thereby improving the adaptability of the HUD. The plane difference between the first fixing portion 101 and the second fixing portion 102 can also enable the HUD device to be installed in a mobile terminal in a variety of possible postures, meet the installation requirements of different types of mobile terminals for the HUD, and further improve the adaptability of the HUD.

[0088] In some other possible designs, the fixing member includes a first positioning structure. The first positioning structure is used to align the connection structure (such as the connection hole) when assembling with the HUD housing, thereby improving the assembly efficiency of the fixing member.

[0089] Exemplarily, the HUD housing is further provided with a first positioning portion, and the first positioning portion corresponds to the first positioning structure in the fixing member. For example, the first positioning structure may be a positioning hole, and the first positioning portion may be a positioning pin, and when the positioning pin is inserted into the positioning structure in the fixing member, the first fixing portion of the fixing member may be aligned with the third fixing portion in the HUD housing, thereby improving the installation efficiency of the fixing member.

[0090] like Figure 6 As shown, the fixing member 10 may include positioning holes 1012a and 1012b. The HUD shell is provided with two protrusions, such as two pins. When the two pins are inserted into the positioning holes 1012a and 1012b, the connecting holes 1011a, 1011b, 1011c and 1011d may correspond to the connecting holes on the HUD shell, so that the fasteners can pass through the connecting holes on the HUD shell and the connecting holes on the fixing member 10, which can greatly improve the installation efficiency.

[0091] like Figure 7 As shown, the fixing member 10 may include positioning holes 1012c and 1012d. The HUD shell is provided with two protrusions, such as two pins. When the two pins are inserted into the positioning holes 1012c and 1012d, the connecting holes 1011e, 1011f, 1011g and 1011h may correspond to the connecting holes on the HUD shell, so that the fasteners can pass through the connecting holes on the HUD shell and the connecting holes on the fixing member 10, which can greatly improve the installation efficiency.

[0092] In some other possible designs, the fixing member includes a second positioning structure. The second positioning structure is used to align the connecting structure (such as the connecting hole) when assembling with the frame, thereby improving the assembly efficiency of the fixing member.

[0093] Optionally, the frame is further provided with a second positioning portion, and the second positioning portion corresponds to the first positioning structure in the fixing member. For example, the second positioning structure may be a protrusion provided on the fixing member, and a corresponding recessed portion is provided on the frame. When the second positioning structure is aligned with the recessed portion of the frame, the first fixing portion of the fixing member may be aligned with the fourth fixing portion in the frame, thereby improving the installation efficiency of the fixing member.

[0094] like Figure 6 and Figure 7 As shown, the fixing member 10 may include a second positioning structure 1022 , and the second positioning structure 1022 may include a pin.

[0095] In some other possible designs, the fixing member is further provided with a third connection structure, and the third connection structure is used to install the components of the mobile terminal. The third connection structure includes a connection hole, a pin and other structures.

[0096] like Figure 6 As shown, the fixing member 10 may include a connection hole 1023, which may be used to fix and install components in the vehicle. Since the space in the mobile terminal is limited, the fixing member may also serve to install other components in some solutions, which not only improves the stability of the installation of components in the mobile terminal, but also helps to reduce the number of components in the mobile terminal.

[0097] In some other possible designs, a plurality of fixing parts for fixing and assembling with the vehicle frame may be provided on the fixing part, and the plurality of fixing parts may be adapted to various types of mobile terminals. Thus, the installation requirements of various types of mobile terminals for HUD may be met through the design of one fixing part, thereby improving the adaptability of the fixing part.

[0098] Exemplarily, the fixing member further includes a fifth fixing portion, and the fifth fixing portion is used to be fixedly assembled with a frame of a second movable terminal, and the second movable terminal is different from the first movable terminal.

[0099] In some other possible designs, one or more weight-reducing holes or weight-reducing cavities may be provided on the fixing member. Figure 6 The lightening holes 104 shown, it should be understood that Figure 6 The number and location of the weight-reducing holes shown are only examples. More or fewer weight-reducing holes may be provided during implementation, and their locations may also be designed in other ways. The weight-reducing holes 104 can reduce the mass of the fixing member 10, which contributes to the lightweight design of the mobile terminal.

[0100] The fixing component is introduced above. The following introduces a HUD device provided in an embodiment of the present application.

[0101] Please refer to Figure 8 , Fig. 9 and Fig.10 The HUD device includes a HUD housing 20 and a fixing member 10 . The HUD housing 20 includes a third fixing portion 201 , and the third fixing portion 201 is used for fixing and connecting with the first fixing portion 101 in the fixing member 10 .

[0102] In some embodiments, the HUD housing 20 may include a plurality of discretely arranged parts. Exemplarily, the HUD housing 20 may include an upper housing and a lower housing, that is, the HUD housing 20 may be composed of an upper housing and a lower housing. Further, the housings of the plurality of parts may be connected by a connecting structure or the like to form the HUD housing 20. In this case, the third fixing portion 201 may be arranged on the lower housing or the upper housing, or partially arranged on the upper housing and partially arranged on the lower housing.

[0103] Optionally, the number of the fixing member 10 may be one or more. As a possible example, when the HUD device includes multiple fixing members 10, the multiple fixing members 10 may be arranged on different sides of the HUD housing 20. Figure 8 and Fig. 9 The number of the fixing parts 10A can be two, which are distinguished as the fixing part 10A and the fixing part 10B for convenience of description. The fixing part 10A and the fixing part 10B are respectively arranged on the left and right sides of the HUD housing. The structures of the fixing part 10A and the fixing part 10B can be respectively referred to Figure 6 and Figure 7 , which will not be explained one by one here.

[0104] Of course, the fixing member 10A and the fixing member 10B may also be provided in an integrated manner, or the fixing member 10A and the fixing member 10B may also be divided into more parts.

[0105] Optionally, the HUD device further includes a fastener 50, which is used to fasten the connection fixture 10 and the HUD housing 20. For example, the fastener 50 can be inserted through the connection hole in the third fixing portion 201 and the connection hole in the first fixing portion 101. Optionally, the fastener includes but is not limited to screw threads, pins, etc., which are not limited in the embodiments of the present application.

[0106] As a possible implementation, Fig. 9The HUD shell is also provided with a first positioning portion 2012, and the first positioning portion 2012 corresponds to the first positioning structure in the fixing member 10A. Exemplarily, the first positioning portion 2012 can be provided in a protruding manner, and the first positioning structure can be provided in a recessed manner, such as a positioning hole. When the first positioning portion 2012 is inserted into the first positioning structure, the first connection hole on the first fixing portion 101 can be aligned with the connection hole on the third fixing portion 201 in the HUD shell 20. Figure 6 and Fig. 9 That is, the connection holes 1011a, 1011b, 1011c and 1011d can be aligned with the positions of the connection holes 2011a, 2011b, 2011c and 2011d respectively, thereby improving the installation efficiency of the fixing parts.

[0107] Similarly, the fixing member 10B may also correspond to the positioning portion on the HUD housing through a positioning structure, which will not be described one by one here.

[0108] As a possible implementation, the HUD shell further includes a sixth fixing part. The sixth fixing part is used for fixing and assembling the frame of the first movable terminal. In some schemes, the HUD shell may include multiple sets of fixing parts, some of which can match some of the fixing parts on the frame, while another part of the fixing on the HUD shell cannot match another part of the fixing part on the vehicle. At this time, the partial fixing parts on the HUD shell that match the frame can be directly fixed and installed with the fixing parts on the frame, while the unmatched partial fixing parts are transferred and installed through fixing parts. In other words, the use of fixing parts can be flexibly set according to actual needs to meet the actual needs of HUD installation.

[0109] Consider a possible situation, combining Fig. 9 The connection holes on the left side of the HUD housing, namely the connection holes 2011a, 2011b, 2011c and 2011d, can match the connection holes on the vehicle frame. In this case, the connection holes on the left side of the HUD housing can be directly assembled with the connection holes on the vehicle frame without using the fixing member 10A for transfer installation. Of course, the fixing member 10B can continue to be used here.

[0110] An embodiment of the present application further provides a HUD system, the HUD system comprising: a HUD optical system, and a fixing member as claimed in any one of the first aspects and / or a HUD device as described in any one of the second aspects.

[0114] In a possible implementation manner, the vehicle frame includes a second positioning portion, and the second positioning portion corresponds to the second positioning structure in the fixing member.

[0115] In a possible implementation, the vehicle frame includes a seventh fixing portion, and the seventh fixing portion is used to be fixedly connected to the HUD shell. In other words, the vehicle frame may include at least two groups of fixing portions, one group is fixedly connected to the HUD shell through a fixing member, and the other group can be directly fixedly connected to the HUD shell.

[0116] In a possible implementation, the mobile terminal includes a second receiving space for receiving the HUD device, the mobile terminal also includes components, the components are located in the second receiving space, and the fixing member is further used to form a first receiving space between the housing of the HUD device and the frame of the mobile terminal to accommodate the components in the mobile terminal.
