Description

Technical Field

[0001] The utility model relates to the technical field of HUD vehicle-mounted devices, in particular to a HUD dust cover protective film and a HUD dust cover. Background Art

[0002] With the advancement of technology, automotive electronics has developed rapidly. Many cars are equipped with HUD (Head-up Display) on-board devices as standard. The dust cover of the HUD device is usually made of transparent plastic material. It does not prevent the dust cover from being worn and scratched during transportation and assembly. After the dust cover is produced, a protective film needs to be affixed to the surface. In order to ensure the complete protection of the entire dust cover, the existing protective film is usually the same shape and size as the surface of the dust cover. This causes the edge of the dust cover protective film to be stuck between the instrument panel and the HUD device when the HUD device is installed. When the protective film needs to be torn off, the edge of the protective film is stuck and difficult to tear off, and the protective film will be damaged and cannot be reused. After the HUD device and the instrument panel are assembled, it is necessary to cover the surface of the dust cover with a protective film again. Since the previous protective film is damaged, a new protective film needs to be used, resulting in a waste of resources and increased production costs. Utility Model Content

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0022] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0023] Example 1, please refer to Figure 1 As shown, this embodiment provides a HUD dust cover protective film, which includes: a protective film body, the protective film body includes a first film body 100 and a second film body 200, the second film body 200 is located at the edge of the first film body 100, and the first film body 100 and the second film body 200 are connected by a connecting film body 300, and the connecting film body 300 breaks when the force exceeds a threshold.

[0024] Please refer to Figure 1 and Figure 2 As shown, Figure 1 A front view of the protective film body provided in this embodiment, Figure 2 The embodiment provided Figure 1 Magnified view of area A.

[0025] In this embodiment, the protective film body includes a first film body 100 located in the central area and a second film body 200 located at the edge of the first film body 100. The first film body 100 and the second film body 200 are connected to each other through a connecting film body 300, so that the first film body 100 and the second film body 200 form a whole, which is convenient for the protective film body to be completely attached to the surface of the HUD dust cover. The connecting film body 300 breaks after the force exceeds the threshold, so that the second film body 200 can be separated from the first film body 100 after the force is applied. It can be understood that the HUD device needs to be installed on the automobile instrument mounting beam, and the dust cover is the topmost component of the HUD device. In order to ensure that the edge of the protective film attached to the surface of the dust cover and the instrument panel located at the top of the dust cover have too small a gap, the edge of the protective film is usually very close to the instrument panel, which causes the protective film attached to the surface of the dust cover to be clamped between the dust cover and the instrument panel. When the protective film needs to be torn off for use, the protective film at the edge is difficult to be torn off, which greatly affects the operator's work progress. The protective film body provided in this embodiment is divided into two separable parts, a first film body 100 and a second film body 200, so that the staff can quickly separate the first film body 100 and the second film body 200. After installing the instrument panel, the staff can apply external force to the second film body 200 through the second action part (500), tear the second film body 200 so that the second film body 200 is separated from the first film body 100, so that the second film body 200 is detached from the dust cover, and the second film body 200 is prevented from being stuck between the dust cover and the external shell and difficult to remove. After the second film body 200 is separated, the first film body 100 is not affected, and the exposed area of ​​the dust cover is protected to prevent the dust cover from being scratched during installation, optical calibration test and transportation. The operator can easily and completely tear off the first film body 100 before optical calibration of the HUD vehicle-mounted equipment.

[0026] After the HUD device is assembled, the staff will first cover the protective film body on the surface of the dust cover. The shape and size of the protective film body and the surface of the dust cover match to ensure that the protective film can completely cover the surface of the dust cover to prevent the surface of the dust cover from being scratched. The HUD device with the protective film body affixed is transported to the assembly workshop and assembled with the automotive instrument mounting beam. The protective film body provides protection for the dust cover. After the instrument panel is assembled, the operator tears off the second film body 200 to separate the second film body 200 from the dust cover, while retaining the first film body 100 to continue to provide protection for the dust cover. After the vehicle assembly and optical calibration test are completed, the user can easily tear off the first film body 100 to use the HUD vehicle-mounted device.

[0027] Optionally, in some implementations of this embodiment, the second film body 200 is arranged around the edge of the first film body 100 , there are multiple film body connecting film bodies 300 , and the multiple connecting film bodies 300 are arranged at intervals along the edge of the first film body 100 to connect the second film body 200 .

[0028] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the second film body 200 is connected to the first film body 100 through a plurality of connecting film bodies 300 arranged at intervals, and the connecting film body 300 breaks after the force exceeds the threshold. The connecting film body 300 forms a connection point to ensure that the first film body 100 and the second film body 200 form a whole, which is convenient for completely pasting the protective film body on the surface of the dust cover, avoiding the misalignment of the first film body 100 and the second film body 200, and also improving the convenience of film pasting and the efficiency of film pasting. The connecting film body 300 is arranged at intervals along the edge of the first film body 100, and a breakpoint is formed between the connecting film bodies 300. When the second film body 200 is separated from the first film body 100, the first film body 100 forms a relatively neat edge, so that the first film body 100 remains relatively intact and can be reused. It can be understood that the HUD vehicle-mounted equipment needs to be optically calibrated after assembly. At this time, the protective film on the dust cover needs to be torn off, and the protective film needs to be re-applied on the dust cover after calibration. When the traditional dust cover protective film is torn off, it is difficult to reuse due to the large outer contour shape. Usually, the manufacturer will replace it with a new protective film of the same size, resulting in a waste of resources. In this embodiment, since the first film body 100 remains relatively intact, it only needs to be protected and stored after being torn off. After the optical calibration is completed, the first film body 100 can be attached back to the surface of the dust cover to achieve the reuse of the first film body 100, thereby saving resources and costs.

[0029] Optionally, in some implementations of this embodiment, the width of each connecting film body 300 is 0.2-0.3 mm.

[0030] Please refer to Figure 2 As shown, in this embodiment, in order to ensure that the connecting film body 300 can be broken smoothly and conveniently, and after breaking, the flatness of the edge of the first film body 100 can be ensured as much as possible. The connecting film body 300 is set to be relatively thin and narrow, and the connecting film body 300 can be broken after being subjected to a small force, so as to separate the first film body 100 from the second film body 200, and avoid that the connecting film body 300 is not broken in time when the second film body 200 is separated, resulting in the first film body 100 being torn, causing the first film body 100 to be damaged or detached from the dust cover. Specifically, the width of the connecting film body 300 is 0.2-0.3mm to meet the connection requirements. When the width of the connecting film body 300 is less than 0.2mm, it is more difficult to process, and the connecting film body 300 is very easy to break. When the protective film body is attached, the connecting film body 300 may break, resulting in the separation of the first film body 100 and the second film body 200, and it is impossible to properly fit the surface of the dust cover. Optionally, when the width of the connecting film body 300 is 0.25 mm, the connecting film body 300 can ensure the connection strength between the first film body 100 and the second film body 200, which is convenient for processing. When the first film body 100 needs to be separated, it can also ensure that the second film body 200 is easily separated without bringing the first film body 100 away from the surface of the dust cover.

[0031] At present, the HUD dust cover on the market is usually set as a square structure, and some special HUD dust covers are set as a circular structure. Therefore, the protective film body provided in this embodiment can be set as a rectangular, circular or polygonal structure that matches the shape of the dust cover. Figure 1 This is the case where the protective film body is set to a rectangular structure.

[0032] Optionally, in some implementations of this embodiment, the distance between two adjacent connecting film bodies 300 is 10-14 mm.

[0033] Please refer to Figure 2 As shown, the connecting film bodies 300 are arranged at intervals. When the interval between two adjacent connecting film bodies 300 is too large, the connection between the first film body 100 and the second film is unstable, which may cause the connecting film body 300 to break, affecting the efficiency of covering the protective film body. On the contrary, when the interval between two adjacent connecting film bodies is too small, the first film body 100 may be damaged or the first film body 100 may be detached from the dust cover when the second film body 200 is separated. Therefore, the spacing between two adjacent connecting film bodies 300 is 10-14mm, which can not only ensure the connection stability between the first film body 100 and the second film body 200, but also facilitate the covering of the protective film body on the dust cover. At the same time, when the second film body 200 is separated, the second film body 200 can be easily torn off without affecting the first film body 100. After the second film body 200 is torn off, the edge of the first film body 100 can also be kept as intact as possible for easy reuse.

[0034] Optionally, in some implementations of this embodiment, a first action portion 400 is provided at an edge of the first film body 100 .

[0035] Please refer to Figure 1 As shown, in this embodiment, a first action portion 400 is provided at the edge of the first film body 100, and the first action portion 400 is connected to the first film body 100, so that the operator can tear off the first protective film from the dust cover through the first action portion 400. It can be understood that the first film is attached to the surface of the dust cover, especially after the second film body 200 is torn off, the edge of the first film body 100 is completely stuck between the dust cover and the instrument panel, and the gap between the two is small, which makes it inconvenient for the user to tear off the first film body 100. By setting the first action portion 400, the first action portion 400 is a strip structure. One end of the first action portion 400 is connected to the first film body 100, and the other end can be folded so that the first action portion 400 does not fit the dust cover, so that the user can pinch the movable end of the first action portion 400 to drive the first film body 100 and tear the first film body 100 off the dust cover, thereby improving the convenience of operation.

[0036] Optionally, in some implementations of this embodiment, a second action portion 500 is provided at the edge of the second film body 200 .

[0037] Please refer to Figure 1 As shown, a second action portion 500 is provided at the edge of the second film body 200, and the second action portion 500 is connected to the second film body 200. The second action portion 500 has the same effect as the first action portion 400, and the user can tear off the second film body 200 through the second action portion 500.

[0038] Optionally, in this embodiment, the second acting portion 500 and the second film body 200 are integrally formed.

[0039] Please refer to Figure 1 As shown, in this embodiment, the protective film body can be processed by cutting a protective film at breakpoints to form the first film body 100 and the second film body 200, and the first film body 100 is cut at breakpoints along the edge of the first film body 100, and the connecting film body 300 is not cut out, and the second film body 200 surrounds the first film body 100. Since the second film body 200 is arranged around the first film body 100, for the convenience of processing, the second action part 500 can be directly cut at the edge of the second film body 200 by cutting to form a strip. The second action part 500 is integrally formed with the second film body 200, saving the operation step of setting the second action part 500 to the second film body 200.

[0040] Optionally, in some implementations of this embodiment, an adhesive layer 600 is provided on the first action portion 400 , and the first action portion 400 is adhered to an edge position of the first film body 100 through the adhesive layer 600 .

[0041] Please refer to Figure 1 As shown, in this embodiment, since the second film body 200 is arranged around the edge of the first film body 100, a first action portion 400 is required to be added so that the user can tear off the first film body 100 through the first action portion 400. The first action portion 400 is directly attached to the edge of the first film body 100 through the adhesive layer 600, so as to facilitate tearing off the first film body 100.

[0042] Optionally, in some implementations of this embodiment, the protective film body is made of polyester material.

[0043] The protective film body can be formed by coating a special protective glue on a transparent optical polyester film (PET), and then laminating a transparent polyester film release film, and laminating a transparent polyester film on the hardened surface. It has a good anti-scratch effect, and the composite polyester film processing technology is relatively mature, low cost, and easy to cut to form the first film body 100 and the second film body 200 in this embodiment.
