Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Figure 1 Exploded view of the LCD screen mounting assembly according to an embodiment of the present utility model.

[0032] As Figure 1 shown, the LCD screen mounting assembly of this embodiment includes a panel 10, an LCD screen cover 20, an LCD screen 30, and a double-sided tape 40. The panel 10 has an opening 11 and a first fixing portion, and the first fixing portion is a clamping portion, including a first clamping portion 121 and a second clamping portion 122.

[0033] The LCD screen cover 20 has a light-transmitting portion 21 (refer to Figure 3 ) and a second fixing portion 22 disposed around the light-transmitting portion 21. The light-transmitting portion 21 is embedded in the opening 11, and the second fixing portion 22 is clamped and fixed to the panel 10 by using the first fixing portion.

[0034] The LCD screen 30 is adhesively fixed to the side of the second fixing portion 22 facing away from the panel 10, and the display area of the LCD screen 30 is correspondingly arranged with the light-transmitting portion 21.

[0035] In the above manner, first, the liquid crystal screen 30 can clearly and intuitively display information such as the current blowing gear. The liquid crystal screen 30 is adhesively fixed in the liquid crystal screen cover 20, and the liquid crystal screen cover 20 is then snap-fitted and fixed to the panel 10. The liquid crystal screen 30 does not directly contact the first fixing portion, avoiding the stress concentration problem caused by the clamping force of the clamping claws directly acting on the liquid crystal screen 30. Secondly, the adhesive fixing method realizes the surface-to-surface contact fixing between the liquid crystal screen 30 and the liquid crystal screen cover 20, which can further effectively avoid stress concentration on the liquid crystal screen 30 and improve the display effect and service life of the liquid crystal screen 30.

[0036] In addition, the liquid crystal screen 30 is adhesively fixed in the liquid crystal screen cover 20 having the light-transmitting portion 21. The display area of the liquid crystal screen 30 is displayed to the user through the light-transmitting portion 21 of the liquid crystal screen cover 20. By providing the liquid crystal screen cover 20, it is possible to prevent foreign objects from entering or external forces from damaging the liquid crystal screen 30 while basically not affecting the display effect of the liquid crystal screen 30.

[0037] It should be noted that although in this embodiment, the first fixing portion and the second fixing portion 22 are fixedly connected to each other by snap-fitting, the present invention is not limited thereto. In other embodiments of the present invention, the first fixing portion and the second fixing portion 22 may also adopt other fixing connection methods, such as threaded connection, riveting or integral molding and other connection forms.

[0038] In this embodiment, the clamping heights of the first clamping portion 121 and the second clamping portion 122 are different. The second fixing portion 22 of the liquid crystal screen cover 20 includes a first screen cover clamping member 221 for cooperating with the first clamping portion 121 for clamping, and a second screen cover clamping member 222 for cooperating with the second clamping portion 122 for clamping.

[0039] Specifically, the clamping height of the first clamping portion 121 is relatively low. The first clamping portion 121 includes a first arm portion 1211 fixed at one end to the inner side of the panel 10, and a first clamping claw 1212 extending obliquely from the end of the first arm portion 1211 away from the panel 10 in a direction close to the panel 10.

[0040] The first screen cover clamping member 221 is provided on a short side of the second fixing portion 22 and is set as a fixed clamping groove 2221 corresponding to the first clamping claw 1212 of the first clamping portion 121. By placing the first clamping claw 1212 of the first clamping portion 121 in the fixed clamping groove 2221 of the first screen cover clamping member 221, the panel 10 and the liquid crystal screen cover 20 are clamped and fixed in corresponding cooperation.

[0041] The clamping height of the second clamping portion 122 is relatively high. The second clamping portion 122 and the first clamping portion 121 are oppositely arranged on both sides of the opening portion 11. The second clamping portion 122 includes a second arm portion 1221 fixed at one end to the inner side of the panel 10, and a second clamping claw 1222 formed by extending obliquely from the end of the second arm portion 1221 away from the panel 10 towards the direction close to the panel 10. The second arm portion 1221 is further provided with a clamping groove 1223.

[0042] The second screen cover clamping member 222 is arranged on the other short side of the second fixing portion 22, and includes two symmetrically arranged fixing blocks 2221 and a clamping block 2222 arranged between the fixing blocks 2221. The clamping block 2222 is arranged in cooperation with the clamping groove 1223. When performing the mating clamping, the clamping block 2222 is placed in the clamping groove 1223 of the second clamping portion 122, and the second clamping claw 1222 is placed at the top of the clamping block 2222 for clamping and limiting. At this time, the two fixing blocks 2221 are respectively located on both sides of the second arm portion 1221.

[0043] In this embodiment, the liquid crystal screen 30 and the surface of the second fixing portion 22 facing away from the panel 10 are bonded and fixed by a double-sided adhesive 40. The outer edge shape of the double-sided adhesive 40 matches that of the liquid crystal screen 30. The double-sided adhesive 40 has a through hole 41. By providing the through hole 41 to expose the display area of the liquid crystal screen 30, it is possible to completely expose the display area of the liquid crystal screen 30 while retaining a relatively large bonding area to ensure the bonding and fixing effect on the liquid crystal screen 30.

[0044] Bonding and fixing the liquid crystal screen 30 in the liquid crystal screen cover 20 by using the double-sided adhesive 40 can achieve surface-to-surface contact fixing between the liquid crystal screen 30 and the liquid crystal screen cover 20, and realize uniform dispersion of stress.

[0045] The assembly method of the liquid crystal screen mounting assembly in this embodiment is as follows:

[0046] First, align the through hole 41 of the double-sided adhesive 40 with the light-transmitting portion 21, and paste the double-sided adhesive 40 on the second fixing portion 22 of the liquid crystal screen cover 20.

[0047] Then, align the display area of the liquid crystal screen 30 with the through hole 41 and the light-transmitting portion 21, and bond the liquid crystal screen 30 to the second fixing portion 22 correspondingly through the double-sided adhesive 40.

[0048] Using the double-sided adhesive 40 can simply and efficiently bond and fix the liquid crystal screen 30 in the liquid crystal screen cover 20, and improve the uniformity of stress distribution.

[0049] The second fixing part 22 further includes a guiding part 223. In this embodiment, the second fixing part 22 has four guiding parts 223 with the same structure, which are divided into two groups. Two guiding parts 223 in each group are arranged at intervals and symmetrically on the two long sides of the second fixing part 22. The guiding part 223 has an inclined guiding surface, which can guide the liquid crystal screen 30, helping the installer quickly determine the position where it should be relative to the second fixing part 22, so as to quickly complete the assembly of the liquid crystal screen 30. Moreover, after the assembly of the liquid crystal screen 30 is completed, the guiding part 223 can also limit the liquid crystal screen 30 to prevent the display area from shifting.

[0050] Finally, the light-transmitting part 21 protruding from the second fixing part 22 toward the side close to the panel 10 is embedded into the opening 11 of the panel 10. The first screen cover engaging part 221 is engaged with the first engaging part 121, and the second screen cover engaging part 222 is engaged with the second engaging part 122, so that the liquid crystal screen cover 20 is stably fixed in the panel 10, and at the same time, the liquid crystal screen 30 adhesively fixed in the liquid crystal screen cover 20 also completes the position fixing.

[0051] In this embodiment, the outer side view of the liquid crystal screen mounting assembly obtained after corresponding assembly is as Figure 2 .

[0052] As Figure 2 shown, in this embodiment, the surface shapes of the opening 11 and the light-transmitting part 21 are both rounded rectangles with a rectangle in the middle and circular arcs on both sides, which is more comfortable visually and has a higher aesthetic degree. At the same time, the edges of the rounded rectangle are smoother, and it is easier to embed the light-transmitting part 21 into the opening 11 during assembly.

[0053] Figure 3 For Figure 2 the A-A cross-sectional view of, as Figure 3 shown, after the assembly is completed, the light-transmitting part 21 is embedded into the opening 11 of the panel 10, further ensuring the position fixing of the liquid crystal screen cover 20, and the end surface of the light-transmitting part 21 away from the liquid crystal screen 30 is flush with the surface of the panel 10, ensuring the overall aesthetic degree of the liquid crystal screen mounting assembly.

[0054] In this embodiment, the inner side view of the liquid crystal screen mounting assembly obtained after corresponding assembly is as Figure 4 .

[0055] As Figure 4As shown, in this embodiment, a first limiting member 50 and a second limiting member 60 are further provided inside the panel 10. After the first screen cover engaging member 221 and the second screen cover engaging member 222 provided on the two short sides of the second fixing portion 22 respectively engage with the first engaging portion 121 and the second engaging portion 122, the first limiting member 50 and the second limiting member 60 are correspondingly located outside the two long sides of the second fixing portion 22. The second fixing portion 22 will be limited in the rectangular area formed by the first engaging portion 121, the second engaging portion 122, the first limiting member 50, and the second limiting member 60, further fixing the position of the liquid crystal screen cover 20.

[0056] Figure 5 For Figure 4 the B-B cross-sectional view of Figure 5 As shown, in this embodiment, through the corresponding engaging cooperation between the first engaging portion 121 and the second engaging portion 122 with different engaging heights and the first screen cover engaging member 221 and the second screen cover engaging member 222, the liquid crystal screen cover 20 can be quickly assembled into the panel 10 and the position can be fixed.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
