DETAILED DESCRIPTION

[0031] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] This embodiment provides a millimeter wave radar 40 assembly device, such as Figure 1As shown, it includes a packing trolley 10, on which a first supporting and limiting structure 20 and a second supporting and limiting structure 30 are relatively arranged. The first supporting and limiting structure 20 is used to limit the millimeter-wave radar 40 in the X direction, the Y direction and the Z direction; the second supporting and limiting structure 30 is used to make the millimeter-wave radar 40 in a planar state and limit the millimeter-wave radar 40 in the X direction, the Y direction and the Z direction; so that the millimeter-wave radar 40 and the millimeter-wave radar bracket 50 can be aligned and assembled.

[0034] Based on the packaging device of this embodiment, this embodiment also provides a method for packaging a millimeter wave radar 40, and the packaging method includes the following steps:

[0035] like Figure 2 As shown, the millimeter wave radar 40 is placed on the first supporting and limiting structure 20;

[0036] Place one end of the millimeter wave radar bracket 50 on the first support and limit structure 20, and the other end on the second support and limit structure 30;

[0037] The millimeter wave radar 40 and the millimeter wave radar bracket 50 are fixed using a tool.

[0038] When assembling the millimeter wave radar 40 and the millimeter wave radar bracket 50, the millimeter wave radar 40 and the millimeter wave radar bracket 50 are aligned and fixed before assembly, which can ensure the assembly accuracy of the millimeter wave radar 40 and the millimeter wave radar bracket 50. Therefore, it is necessary to fix the millimeter wave radar 40 and the millimeter wave radar bracket 50 while ensuring the alignment of the millimeter wave radar 40 and the millimeter wave radar bracket 50.

[0039] Therefore, the first supporting and limiting structure 20 and the second supporting and limiting structure 30 of the present embodiment can realize alignment and fixation at the same time after the millimeter wave radar 40 and the millimeter wave radar bracket 50 are placed.

[0040] The millimeter wave radar 40 is preferably fixed so as to be unable to move in the X, Y and Z directions; similarly, the millimeter wave radar bracket 50 is preferably fixed so as to be unable to move in the X, Y and Z directions.

[0041] The alignment of the millimeter wave radar 40 and the millimeter wave radar bracket 50 can be that the millimeter wave radar 40 is above the millimeter wave radar bracket 50, or that the millimeter wave radar bracket 50 is located above the millimeter wave radar 40. In the manner in which the millimeter wave radar bracket 50 is located above the millimeter wave radar 40, during assembly, the assembly screws and the like are penetrated on the bracket, which can reduce the manufacturing difficulty and manufacturing cost of the millimeter wave radar 40.

[0042] The first support and limit structure 20 can also play a supporting or support and limit role for the millimeter wave radar bracket 50. Figure 3 As shown in the figure, the first support limit structure 20 is provided with a support platform 24, which can be used to support the millimeter wave radar bracket 50; this can further improve the alignment accuracy of the millimeter wave radar 40 and the millimeter wave radar bracket 50, and thus further improve the accuracy of assembly; and because the side of the millimeter wave radar 40 close to the millimeter wave radar bracket 50 and the side of the millimeter wave radar bracket 50 close to the millimeter wave radar 40 are both irregular, if the millimeter wave radar bracket 50 falls directly on the millimeter wave radar 40, it is difficult to form a stable support, which increases the difficulty of assembly.

[0043] Figure 3 In the figure, the support platform 24 can only play a supporting role. If the limiting function of the first millimeter-wave radar bracket 50 is to be realized, a limiting boss can be set on each of the two support platforms 24. However, in fact, as long as the second support limiting structure 30 has the supporting and limiting function, the alignment and fixation of the millimeter-wave radar bracket 50 and the millimeter-wave radar 40 can be guaranteed.

[0044] In order to achieve the fixation of the millimeter wave radar 40 in the X direction, Y direction and Z direction, in some embodiments, as shown in FIG. Figure 3 As shown, the first support and limit structure 20 includes a first support and limit body 21, and a first limit groove 22, a first positioning hole 23 and a support platform 24 arranged on the top surface of the first support and limit body 21, and the first limit groove 22 and the first positioning hole 23 cooperate to achieve support and limitation of the millimeter-wave radar; the support platform 24 is used to support one end of the millimeter-wave radar bracket 50.

[0045] The millimeter wave radar 40 includes a millimeter wave radar body and a millimeter wave radar plug. The first limiting groove 22 is a positioning groove imitating the millimeter wave radar body, and the first positioning hole 23 is a positioning hole imitating the millimeter wave radar plug. The first limiting groove 22 is used to place the millimeter wave radar body, and the first positioning hole 23 is used to place the millimeter wave radar plug, so as to achieve the limiting effect on the millimeter wave radar 40;

[0046] In order to further improve the support stability of the millimeter wave radar bracket 50, in some embodiments, such as Figure 3 As shown, the first limiting groove 22 , the first positioning hole 23 and the second supporting limiting structure 30 are located on the same straight line and on both sides of the straight line, and a supporting platform 24 is respectively provided on both sides of the first limiting groove 22 .

[0047] In some embodiments, Figure 3 As shown, a hole 241 is provided on the upper surface of the support platform 24. The hole 241 is used to fix the support platform 24 and the dispensing trolley 10.

[0048] In order to further improve the support stability of the millimeter wave radar bracket 50, in some embodiments, such as Figure 4 As shown, the straight line where the two support platforms 24 are located is perpendicular to the straight line where the first limiting groove 22 and the first positioning hole 23 are located.

[0049] In some embodiments, Figure 4 As shown, the first limiting groove 22 is arranged close to the second supporting limiting structure 30 , and the first positioning hole 23 is arranged away from the second supporting limiting structure 30 .

[0050] In order to achieve the fixation of the millimeter wave radar bracket 50 in the X direction, Y direction and Z direction, in some embodiments, as shown in FIG. Figure 5 As shown, the second support and limiting structure 30 includes a second support and limiting body 31 and a second limiting groove 32 arranged on the top surface of the second limiting body, and the second limiting groove 32 is used to set the other end of the millimeter wave radar bracket 50 to achieve a limiting effect on the millimeter wave radar bracket 50.

[0051] It should be noted that the second support and limiting structure 30 can fix the millimeter wave radar bracket 50 in the X direction, Y direction and Z direction by coordinating with the structural features of the millimeter wave radar bracket 50 itself. Figure 2 As shown, the millimeter wave radar bracket has the characteristics of being large at both ends and small in the middle, and the small part in the middle is arranged in the second limiting groove 32, so that the millimeter wave radar bracket 50 is fixed in the X direction, Y direction and Z direction.

[0052] In some embodiments, Figure 5 As shown, the second supporting and limiting body 31 includes a supporting block bottom plate 311, a supporting block 312 and a limiting block 313. The lower end of the supporting block bottom plate 311 is fixedly connected to the packaging trolley 10, and the upper end is fixedly connected to the lower end of the supporting block 312. The upper end of the supporting block 312 is fixedly connected to the lower end of the limiting block 313, and the upper end of the limiting block 313 is provided with the second limiting groove 32.

[0053] in, Figure 5 In the embodiment, the support block bottom plate 311 is also provided with waist-shaped holes, and the waist-shaped holes are used to fix the support block bottom plate 311 and the dispensing trolley 10.

[0054] like Figure 5 As shown in more detail, the notch of the second limiting groove 32 is provided with a slope, which makes it easier to place the millimeter wave radar bracket 50.

[0055] A more detailed subassembly method is: place the millimeter-wave radar body of the millimeter-wave radar 40 in the first limiting groove 22, and at the same time place the millimeter-wave radar insert of the millimeter-wave radar 40 in the first positioning hole 23. The first limiting groove 22 and the first positioning hole 23 simultaneously limit the displacement of the millimeter-wave radar 40 in the X and Y directions in a planar state, as well as the Z direction position setting.

[0056] One end of the millimeter wave radar bracket 50 is placed in the second limiting groove 32 to limit the displacement of the millimeter wave radar bracket 50 in the X and Y directions and fix the position in the Z direction; the other end is placed on the support platform 24.

[0057] The millimeter wave radar 40 and the millimeter wave radar bracket 50 are fixed by using tools to be connected into a standard part.
