[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0027] Reference Figures 1 to 3 As shown, the instrument panel upper cover of the embodiment of the utility model is made into the following embodiment.

[0028] The instrument panel upper cover includes a main body 100 and an air duct housing 200 .

[0029] Reference Figure 1As shown, a duct profile 110 is provided at the bottom of the main body 100. The duct profile 110 surrounds the bottom surface of the main body 100. The duct profile 110 forms a notch on the rear side of the main body 100. A welding column 120 is provided at the bottom of the duct profile 110, and the welding column 120 protrudes downward.

[0030] Reference Figure 2 As shown, a downwardly concave duct cavity 210 is provided on the top of the duct shell 200. The outer shape of the duct cavity 210 is set according to the shape of the duct profile 110. The edge of the duct cavity 210 is provided with a plurality of positioning holes 220 that pass through the upper and lower parts. The positions of the plurality of positioning holes 220 are set in a one-to-one correspondence with the positions of the plurality of welding columns 120.

[0031] The duct housing 200 is mounted on the bottom of the main body 100, with the edge of the duct cavity 210 aligned with the duct profile 110. The welding posts 120 are inserted into the positioning holes 220 in a corresponding manner. Ultrasonic welding equipment is then used to weld the welding posts 120 to the positioning holes 220. This completes the assembly of the main body 100 and the duct housing 200, making assembly of the main body 100 and the duct housing 200 more convenient and improving production efficiency.

[0032] In some embodiments, reference Figure 2 and Figure 3 As shown, a plurality of welding grooves 230 are provided on the edge of the air duct cavity 210 , each welding groove 230 is recessed downward, and the positions of the plurality of welding grooves 230 correspond one-to-one to the positions of the plurality of positioning holes 220 , and the positioning holes 220 are provided in the welding grooves 230 .

[0033] When assembling the air duct shell 200 and the main body 100, before the welding column 120 is inserted into the positioning hole 220, the welding groove 230 and the welding column 120 are used for simple positioning to ensure that the deviation distance between the welding column 120 and the positioning hole 220 is small, making the operation of inserting multiple welding columns 120 into multiple positioning holes 220 one by one more convenient, thereby improving production efficiency.

[0034] In some embodiments, reference Figure 3 As shown, the depth of the weld groove 230 is less than the length of the weld post 120 .

[0035] The welding column 120 is limited in the welding groove 230. In order to ensure that the welding column 120 is welded with the positioning hole 220, the welding column 120 needs to pass through the welding groove 230 and be inserted into the positioning hole 220. After ensuring that the welding column 120 extends downward from the positioning hole 220, the ultrasonic welding equipment can weld the part of the welding column 120 extending from the positioning hole 220 to the bottom of the welding groove 230.

[0036] In some embodiments, a plurality of radially arranged reinforcing ribs 130 are disposed on the periphery of the welding column 120 , and the reinforcing ribs 130 abut against the bottom inner wall of the welding groove 230 .

[0037] Utilizing the multiple reinforcing ribs 130 of the welding column 120 to abut against the bottom inner wall of the welding groove 230 helps to limit the length of the welding column 120 extending below the positioning hole 220, and helps to fix the welding column 120 and related parts such as the welding groove 230 during the welding process, thereby preventing the above-mentioned components from shaking up and down and causing welding deviation.

[0038] In some embodiments, reference Figure 1 and Figure 2 As shown, the outer shape of the air duct housing 200 matches the shape of the air duct profile 110 , and the positioning holes 220 are set at the outer edge of the air duct housing 200 .

[0039] The shape of the duct shell 200 is designed according to the shape of the duct profile 110, which helps to save materials for making the duct shell 200. When assembling the duct shell 200 and the main body 100, the operator can easily observe the fit between the outer edge of the duct shell 200 and the duct profile 110, so as to quickly locate the assembly position of the duct shell 200 on the duct profile 110.

[0040] In some embodiments, reference Figure 2 and Figure 3 As shown, a plurality of welding slots 230 are provided on the edge of the air duct housing 200 , and each welding slot 230 is open toward the side wall outside the air duct housing 200 .

[0041] When assembling the air duct shell 200 and the main body 100, when inserting the welding column 120 into the welding groove 230, the operator can observe from the outside of the air duct shell 200 whether the welding column 120 is located in the welding groove 230; since the main body 100 and the air duct shell 200 have a large area, the main body 100 and the air duct shell 200 are prone to slight deformation, resulting in the welding column 120 and the positioning hole 220 not corresponding, so the welding groove 230 open on the outside also helps the operator to observe whether the welding column 120 is accurately inserted into the positioning hole 220.

[0042] In some embodiments, reference Figure 2 As shown, an abutment block 240 is provided on the top of the air duct cavity 210 . After the air duct housing 200 and the main body 100 are assembled, the abutment block 240 abuts against the bottom of the main body 100 .

[0043] The abutment block 240 helps to support the defrost duct formed by the duct cavity 210 and the duct profile 110 , and prevents the defrost duct from collapsing.

[0044] In some embodiments, reference Figure 1 and Figure 2As shown, the main body 100 and the air duct shell 200 are assembled to form a defrost air duct. A defrost air outlet 140 is provided on the front side of the main body 100. The defrost air outlet 140 passes through the main body 100 up and down, and the defrost air outlet 140 connects the defrost air duct with the outside world. A defrost air inlet 250 is provided on the rear side of the air duct shell 200. The defrost air inlet 250 passes through the air duct shell 200 backward, and the defrost air inlet 250 connects the defrost air duct with the outside world, so that external warm air or cold air equipment can be connected to the defrost air inlet 250.

[0045] In some embodiments, the air duct profile 110 is convex downward.

[0046] When assembling the air duct housing 200 and the main body 100 , the downwardly protruding air duct profile 110 helps the operator to align the edge of the air duct cavity 210 of the air duct housing 200 with the air duct profile 110 , thereby improving assembly efficiency.

[0047] The utility model also provides an instrument panel assembly, comprising the instrument panel upper cover as described in the above embodiment.

[0048] When producing the instrument panel cover, the outer edge of the duct cavity 210 of the duct shell 200 is aligned with the duct profile 110 of the main body 100, so that the positions of the multiple positioning holes 220 correspond one-to-one to the positions of the multiple welding columns 120, and then the multiple welding columns 120 are inserted one-to-one into the multiple positioning holes 220. After that, ultrasonic welding equipment is used to weld the welding columns 120 and the positioning holes 220 together to complete the assembly of the main body 100 and the duct shell 200, making the assembly of the main body 100 and the duct shell 200 more convenient and improving production efficiency.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
