[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See Figure 2 The head-up display assembly includes a control board 10 and a power interface 20. The control board 10 is generally a PCBA board. The edge of the control board 10 includes multiple positioning holes 101. The control board 10 also includes multiple interfaces 102, which protrude from the plane of the control board 10.

[0030] See Figures 1-3This application provides a fixing fixture for the aforementioned head-up display assembly. The fixture includes a base 1 and a cover plate 2. The base 1 has a positioning groove 3, which matches the shape of the control board 10, for supporting and positioning the control board 10 and the power interface 20. The cover plate 2 is rotatably connected to the base 1, forming a limiting space with the positioning groove. The positioning groove 3 at least partially contacts the control board 10 and the power interface 20. The limiting space restricts the displacement of the control board 10 and the power interface 20.

[0031] It should be noted that one side of the cover plate 2 is hinged to the base 1. The cover plate 2 and the base 1 can be rotated to close and open. When the cover plate 2 closes the base 1, the cover plate 2 at least partially covers the positioning groove 3. The cover plate 2 and the positioning groove 3 together form a limiting space.

[0032] In some embodiments, the positioning slot 3 includes a first positioning slot 31 and a second positioning slot 32, wherein the first positioning slot 31 is used to fit the control board 10 and the second positioning slot 32 is used to fit the power interface 20.

[0033] It should be noted that when locking is required, the control board 10 and the power interface 20 have been initially assembled to form a component. The component is placed in the positioning slot 3. The control board 10 of the component is partially matched and placed in the first positioning slot 32, and the power interface 20 of the component is partially matched and placed in the second positioning slot 32.

[0034] In some embodiments, the first positioning groove 31 is provided with a plurality of support blocks 33, which are used to at least partially support the control plate 10, so that the control plate 10 is suspended in the first positioning groove 31.

[0035] Specifically, the height of the support block 33 is lower than the depth of the first positioning groove 31, thus forming a stepped groove with the inner wall of the positioning groove 3. The control plate 10 is placed on the stepped groove formed on the support block 33. This stepped groove prevents the control plate 10 from contacting the a-side of the positioning groove 3, creating a partially contacted and partially suspended state, thereby preventing damage to the electronic components on the back of the control plate 10 during locking. The part of the control plate 10 that contacts the support block 22 is the part without electronic components, thus avoiding damage to the electronic components.

[0036] In some embodiments, at least two of the support blocks 33 are provided with positioning posts 34, which match the positioning holes 101 on the control board 10; that is, the head-up display assembly is positioned by fitting the positioning holes 101 of the control board 10 onto the positioning posts 34.

[0037] Specifically, multiple support blocks 33 are provided, spaced apart. For example, the support blocks 33 include a first support block 331, a second support block 332, a third support block 333, a fourth support block 334, a fifth support block 335, and a sixth support block 336. The first support block 331 and the fourth support block 334 are diagonally opposite each other along one diagonal, and the second support block 332 and the sixth support block 336 are diagonally opposite each other along another diagonal. Positioning posts 34 are provided on the first support block 331 and the fourth support block 334, or on the second support block 332 and the sixth support block 336. By using positioning posts 34 on at least two support blocks 33, the control panel 10 can be placed quickly. Of course, more positioning posts 34 can be set. Multiple positioning posts 34 can be set on 3 support blocks 33, 4 support blocks 33...6 support blocks 33 respectively. There can also be 8, 9, 15 support blocks 33, etc., which are not limited here.

[0038] In some embodiments, the base 1 further includes a material receiving groove 4, which is connected to the first positioning groove 31.

[0039] It should be noted that the material chute 4 is located on both sides away from the second positioning chute 32, so that the user can easily pick up the head-up display assembly.

[0040] In some embodiments, the cover plate 2 has a first protrusion 21 on the side near the base 1, which is used to match and correspond with the second positioning groove 32. That is, when the head-up display assembly is placed in the positioning groove 3 and the cover plate 2 is closed on the base 1, the first protrusion 21 abuts against the part of the power interface 20 that protrudes from the control board 10 to longitudinally limit the power interface 20.

[0041] In some embodiments, the cover plate 2 further includes at least two second protrusions 22, at least two third protrusions 23, and at least two grooves 24 on the side near the base 1; wherein the second protrusions 22 and the third protrusions 23 are used to press against the edge of the control plate 10, and the grooves 24 are used to avoid the protruding elements of the control plate 10.

[0042] Specifically, the control board 10 includes four positioning holes 101 on its edge. The second protrusion 22 corresponds to the two positioning holes 101 on the control board 10 near the power interface 22, and the third protrusion 23 corresponds to the two positioning holes 101 on the control board 10 away from the power interface 22. When the head-up display assembly is placed in the positioning groove 3 and the cover plate 2 is closed on the base 1, the second protrusion 22 abuts against the two positioning holes 101 on the control board 10 near the power interface 22, and the third protrusion 23 abuts against the two positioning holes 101 on the control board 10 away from the power interface 22. There are no electronic components at the location of the positioning holes 101 on the control board 10, and using the protrusions to abut against this location can reduce damage. Since there are many electronic components around the area where the second protrusion 22 abuts, to avoid the second protrusion 22 damaging other components on the control board 10, the second protrusion 22 can be wrapped with a soft material, such as felt. Of course, the second protrusion 22 can also be made of a soft material, which is not limited here.

[0043] It should be noted that the control board 10 also includes multiple protruding elements, such as multiple interfaces 102 protruding from the plane of the control board 10. In order to avoid damage to the protruding elements after the cover plate 2 is closed on the base 1, multiple grooves 24 are opened on the cover plate 2 to avoid the protruding elements of the control board 10.

[0044] In some embodiments, the base 1 is provided with a magnetic element 11, and the cover plate 2 is provided with a magnetic element 25; when the cover plate 2 is closed on the base 1, the magnetic element 11 and the magnetic element 25 are attracted and connected. The magnetic elements 11 and 25 have opposite magnetic properties to achieve a stable closing of the cover plate 2 and the base 1.

[0045] In some embodiments, the cover plate 2 is provided with a through hole 26, which corresponds to the locking position of the power interface 20.

[0046] Specifically, after the power interface 20 and the control board 10 are assembled, there is a locking hole 30 between them. After the cover plate 2 is closed on the base 1, the locking hole 30 is exposed from the through hole 26, so as not to affect the normal locking of the screw-locking device.

[0047] It should be noted that when using this tooling, the base 1 can be fixed on the mounting plate (not shown) of the screw-locking device. The mounting plate of the screw-locking device can be equipped with a sliding mechanism (not shown) to drive the tooling to move, making it convenient for users to install and remove the head-up display components.

[0048] In some of these embodiments, reference is made to Figures 4-6The base 1 is provided with an adjustment groove 12 and a spring 13. An L-shaped plate 14 is connected to the adjustment groove 12 by the spring 13. The L-shaped plate 14 includes a handle end b and a partition end c at both ends. The L-shaped plate 14 moves within the adjustment groove 12. If the operator is distracted or focuses on speed rather than quality, the base 1 and the cover plate 2 may not be fully closed. Forcing the base 1 and the cover plate 2 to close may also cause damage to the surface of the control plate 10 if excessive force is used to flip and close the cover plate 2. Therefore, when the cover plate 2 is rotated upwards to close it, the cover plate 2 will not be able to continue rotating after encountering the partition end c. At this time, a preset gap is left between the cover plate 2 and the base 1. Then, the handle end b is pulled, causing the L-shaped plate 14 to move closer to the spring 13. The L-shaped plate 14 is disengaged from the flipping trajectory of the cover plate 2, and the spring 13 is compressed. After the hand leaves the handle end b, the L-shaped plate 14 stays on the outside. The cover plate 2 falls under its own weight, and magnetic component 11 and magnetic component 25 are attracted together. If the control board 10 and power interface 20 are not properly positioned, magnetic component 11 and magnetic component 25 will not be attracted together, and there will be a gap between them. They need to be removed and repositioned. When excessive force is used to close the cover, the excessive force applied by the user will be blocked by the L-shaped plate 14 and will not directly act on the control board 10, thus protecting the control board 10 and preventing damage to it due to improper operation.

[0049] When the cover plate 2 is flipped up and reset again, the spring force of the spring 13 causes the L-shaped plate 14 to slide back and reset, and the partition end c enters the flipping trajectory of the cover plate 2 again.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0051] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0052] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0053] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
