[0031] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0033] The inventor has found through research that in the prior art, Figure 1 As shown, the housing of the in-vehicle display device is positioned between the back cover 200 and the middle frame 100 solely through contact between the rear end surface of the middle frame 100 and the back cover 200. However, the middle frame 100 itself has certain thickness requirements, which limits the width of the rear end surface of the middle frame 100. As a result, the contact area between the back cover 200 and the middle frame 100 is limited to the rear end surface of the middle frame. This small contact area results in unstable assembly and positioning between the back cover 200 and the middle frame 100, which can easily cause undesirable phenomena such as cracks and abnormal noises over time.

[0034] In order to solve the above technical problems, the present invention provides a vehicle-mounted display device housing, such as Figure 3 、 Figure 4 and Figure 5 As shown, the housing of the vehicle-mounted display device includes a middle frame 1, a back cover 3 and an extension portion 2; one end of the extension portion 2 is connected to the inner wall of the middle frame 1, and the other end of the extension portion 2 extends into the middle frame 1 and tilted backward; the back cover 3 is located on the back side of the extension portion 2 and the middle frame 1, and is respectively fitted with the middle frame 1 and the extension portion 2.

[0035] In the present application, the extension portion 2 is added to the inner side of the middle frame 1, and the extension portion 2 is extended inward and backward of the middle frame 1, so that the end of the extension portion 2 away from the middle frame 1 can be closer to the back cover 3. When the middle frame 1 and the back cover 3 are assembled, the extension portion 2 can contact the back cover 3, thereby increasing the contact area between the middle frame 1 and the back cover 3, improving the assembly stability between the back cover 3 and the middle frame 1, and reducing the probability of cracks or abnormal noises caused by unstable assembly positioning between the back cover 3 and the middle frame 1.

[0036] In one embodiment of this application, Figure 4 and Figure 5 As shown, the extension portion 2 includes a planar segment 21 and a curved segment 22; one end of the planar segment 21 is connected to the inner wall of the middle frame 1, and the other end of the planar segment 21 extends into the middle frame 1; one end of the curved segment 22 is connected to an end of the planar segment 21 away from the middle frame 1, and the other end of the curved segment 22 extends obliquely backward relative to the middle frame 1.

[0037] In this embodiment, the planar segment 21 and the curved segment 22 are arranged in sequence toward the center of the middle frame 1, thereby forming the extension portion 2 extending inward and backward, so that the back cover 3 can be in contact with both the middle frame 1 and the extension portion 2, thereby increasing the contact area between the middle frame 1 and the back cover 3 and improving the assembly stability between the middle frame 1 and the back cover 3.

[0038] Specifically, the planar section 21 is used to enable the extension portion 2 to extend toward the interior of the middle frame 1, and the curved section 22 is used to enable the extension portion 2 to extend obliquely toward the rear side of the middle frame 1, so that the curved section 22 can be closer to the inner wall of the back cover 3, thereby cooperating with the inner wall of the back cover 3; the planar section 21 is mainly used to fit in contact with the rear end surface of the back cover 3, and the curved section 22 is mainly used to fit in contact with the inner wall of the back cover 3, so as to increase the contact area between the middle frame 1 and the back cover 3 and improve the stability of the assembly between the middle frame 1 and the back cover 3.

[0039] It should be noted that the extension portion 2 is annular and is arranged around the inner wall of the middle frame 1, thereby extending along the four sides of the back cover 3 toward the inner wall of the back cover 3 and in close contact with the back cover 3, thereby maximizing the contact area between the middle frame 1 and the back cover 3 while ensuring that no adverse interference is caused to the components installed on the back cover 3.

[0040] like Figure 5As shown, the back cover 3 includes a back cover body 31 and an annular arc surface segment 32; the back cover body 31 is arranged in a plane; the annular arc surface segment 32 is arranged around the periphery of the back cover body 31; the annular arc surface segment 32 is extended forward away from one end of the back cover body 31 to form a accommodating space together with the back cover body 31.

[0041] Specifically, the annular arc segment 32 and the curved surface segment 22 are both arc-shaped, and are both arranged to be concave toward the rear. The concave curvature of the annular arc segment 32 and the curved surface segment 22 cooperate with each other, so that the inner wall of the annular arc segment 32 fits the curved surface segment 22.

[0042] In one implementation of this embodiment, the angle at which the curved surface segment 22 is tilted backward relative to the flat surface segment 21 is an acute angle, and the angle at which the annular arc surface segment 32 is tilted forward relative to the rear cover body 31 is an acute angle, which not only meets the requirement of increasing the contact area by fitting the arc surface, but also facilitates processing and manufacturing.

[0043] In one embodiment of this application, Figure 5 As shown, a mounting plane 4 is provided on the annular arc surface segment 32 , and the mounting plane 4 is arranged opposite to the plane segment 21 and fits with the plane segment 21 .

[0044] Specifically, the mounting plane 4 is located at one end of the annular arc segment 32 away from the back cover body 31 and is arranged forward, so that the mounting plane 4 can be parallel to and opposite to the plane segment 21. When the back cover 3 is assembled with the middle frame 1, the mounting plane 4 can fit with the plane segment 21.

[0045] In this embodiment, the mounting plane 4 is provided at one end of the annular arc surface segment 32 away from the back cover body 31 to form a plane, so that the mounting plane 4 can be parallel to the plane segment 21 and fit with each other. Then, the fit between the extension portion 2 and the back cover 3 includes both the fit of the arc surface between the annular arc surface segment 32 and the curved surface segment 22, and the fit of the plane between the mounting plane 4 and the plane segment 21, thereby maximizing the contact area between the middle frame 1 and the back cover 3, improving the assembly stability between the back cover 3 and the middle frame 1, and reducing the probability of cracks or abnormal noises caused by unstable assembly positioning between the back cover 3 and the middle frame 1.

[0046] In one embodiment of the present application, the middle frame 1 and the extension portion 2 are an integrally formed structure.

[0047] Specifically, the middle frame 1 and the extension portion 2 are formed into an integrally formed structure by injection molding, so that the middle frame 1 and the extension portion 2 become a whole, thereby ensuring the stability of the connection between the middle frame 1 and the extension portion 2.

[0048] The middle frame 1 is an electroplatable middle frame 1, and the extension portion 2 is an electroplatable extension portion. That is, the middle frame 1 and the extension portion 2 are made of electroplatable materials to facilitate subsequent electroplating.

[0049] It should be noted that the middle frame 1 and the back cover 3 described in this application are not electroplated before assembly to prevent the outer surfaces of the middle frame 1 and the extension 2 from being affected by electroplating and affecting their contact and fit with the back cover 3. After the back cover 3 and the middle frame 1 are assembled, the middle frame 1 and the extension 2 are electroplated. This ensures the assembly stability between the back cover 3 and the middle frame 1 while improving the aesthetic appearance of the middle frame 1, making it more in line with the interior design requirements. The back cover 3 is located in the hidden area behind the vehicle-mounted display device, so electroplating is not required to improve the appearance of the back cover 3.

[0050] In one embodiment of the present application, the mounting plane 4 is partially fitted with the back surface of the middle frame 1 .

[0051] Specifically, only a portion of the back surface of the middle frame 1 is in contact with the mounting plane 4, so that the outer portion of the back surface of the middle frame 1 can be exposed (e.g. Figure 2 As shown); then, after the middle frame 1 is electroplated, an annular electroplating layer can be formed on the periphery of the rear cover 3, providing better appearance quality, increasing glossiness and texture, making it look more beautiful and more in line with the interior design requirements, while increasing the wear resistance, corrosion resistance and weather resistance of the surface of the middle frame 1, and enhancing the service life and strength of the middle frame 1.

[0052] The back cover 3 is laser welded to the middle frame 1 and the extension portion 2 ; the middle frame 1 is a light-transmitting middle frame 1 , the extension portion 2 is a light-transmitting extension portion 2 , and the back cover 3 is a non-light-transmitting back cover 3 .

[0053] Specifically, the middle frame 1 and the extension part 2 are both light-transmissive, while the back cover 3 is not light-transmissive. When the back cover 3 is laser-welded to the middle frame 1 and the extension part 2, the optical fiber passes through the light-transmissive middle frame 1 and the extension part 2 to reach the back cover 3; due to the light-opaque nature of the back cover 3, after the back cover 3 is irradiated by the laser, the surface of the back cover 3 melts at high temperature, so that the back cover 3 is respectively fused to the middle frame 1 and the extension part 2.

[0054] Therefore, in this application, the middle frame 1 and the extension portion 2 are first injection molded, and then the back cover 3 is injection molded. Then, the mounting plane 4 is fitted with the plane segment 21, and the annular arc segment 32 is fitted with the curved segment 22. The back cover 3 is respectively welded to the middle frame 1 and the extension portion 2 by laser welding, thereby completing the assembly of the back cover 3 and the middle frame 1.

[0055] In the prior art, the middle frame 1 and the back cover 3 are assembled by hot melt. During this process, the hot melt head protrudes from the surfaces of the middle frame 1 and the back cover 3. Furthermore, a gap exists between the back cover 3 and the middle frame 1 during hot melt assembly, which can easily cause abnormal noise due to vibration after long-term use. However, the present application utilizes lamination and laser welding of the back cover 3, the middle frame 1, and the extension 2 to solve these problems associated with conventional hot melt assembly of the middle frame 1 and the back cover 3.

[0056] In one embodiment of the present application, the middle frame 1 and the extension portion 2 are both made of transparent PC (polycarbonate) material or PC+ABS (acrylonitrile-butadiene-styrene) modified plastic material. Alternatively, a modified wave-transparent PC (polycarbonate) material or PC+ABS (acrylonitrile-butadiene-styrene) modified plastic material may be used. Electroplating-grade PC or PC+ABS has excellent electroplating adhesion. These materials can form a smooth and uniform surface during the electroplating process, ensuring strong adhesion and durability of the electroplated layer, and improving the gloss and texture of the appearance.

[0057] The back cover 3 is made of a black or dark non-electroplating PC material, or can be made of a black or dark non-electroplating PC+ABS modified plastic material.

[0058] In the present application, the back cover 3 and the overall structure of the middle frame 1 and the extension portion 2 are obtained by injection molding, and then the back cover 3, the middle frame 1 and the extension portion 2 are welded and assembled by laser welding, and then the middle frame 1 is electroplated.

[0059] The housing of the vehicle-mounted display device further includes a nickel covering layer, a copper covering layer and a chromium covering layer, and the nickel covering layer, the copper covering layer and the chromium covering layer constitute the electroplating layer on the outer surface of the extension portion 2 and the middle frame 1 .

[0060] The nickel covering layer covers the outer surfaces of the extension 2 and the middle frame 1, the copper covering layer covers the outer surface of the nickel covering layer, and the chromium covering layer covers the outer surface of the copper covering layer. The multi-layer electroplating of nickel, copper, and chromium provides excellent corrosion protection, enhanced adhesion and durability, improved surface decorative effects, and increased hardness and wear resistance for the middle frame 1 and the extension 2. Each layer of electroplating material has its own specific functions and advantages, thereby comprehensively improving the performance and appearance of the product.

[0061] Specifically, nickel, as the first layer of electroplating material, exhibits excellent corrosion resistance and rust resistance. The nickel coating provides protection, preventing the substrates of the middle frame 1 and the extension 2 from environmental corrosion. The copper coating, as the second layer of electroplating, is primarily used to fill minor pits and unevenness on the surfaces of the substrates of the middle frame 1 and the extension 2, making their surfaces smoother, thereby improving the adhesion of the entire plating system and the uniformity of the electroplated layer. The chromium coating, as the outermost coating, provides a unique visual effect and texture, offering both a metallic texture and a matte appearance, reducing glare and creating a more sophisticated and refined appearance. This meets specific aesthetic requirements and enhances the product's aesthetics and market competitiveness.

[0062] The present application also provides a vehicle-mounted display device, which includes the vehicle-mounted display device housing as described in any one of the above items.

[0063] In summary, the present application provides a vehicle-mounted display device housing and a vehicle-mounted display device, which include a middle frame; a back cover; an extension portion, one end of which is connected to the inner wall of the middle frame, and the other end of which extends inwardly and backwardly into the middle frame; the back cover is located on the back side of the extension portion and the middle frame, and is respectively fitted with the middle frame and the extension portion. In the present application, the extension portion is added to the inner side of the middle frame, and the extension portion is extended inwardly and backwardly into the middle frame, so that the end of the extension portion away from the middle frame can be closer to the back cover. When the middle frame and the back cover are assembled, the extension portion can contact the back cover, thereby increasing the contact area between the middle frame and the back cover, improving the assembly stability between the back cover and the middle frame, and reducing the probability of cracks or abnormal noises caused by unstable assembly positioning between the back cover and the middle frame.
