[0035] With the popular application of the vehicle air conditioner in the rear seat air outlet, and further improving the application of the rear end evaporator bracket, in order to solve the problem of large welding difficulty and low structural strength of the existing rear evaporator bracket structure, the application provides a rear end evaporator bracket 10, Figure 1 It is a structural schematic diagram of a rear end evaporator bracket, Figure 2 It is a sectional structure schematic diagram of a rear end evaporator bracket, as shown in Figure 1 And Figure 2 As shown, the rear end evaporator bracket 10 includes a base plate 11 and a bracket 12 formed by stamping from the bottom of the base plate 11; the bracket 12 includes an arc-shaped connecting wall 121 and a mounting wall 122 connected together, and the vertical projection of the mounting wall 122 on the base plate 11 at least partially coincides with one side edge of the base plate 11;

[0036] At least two positioning mounting holes 1221 are arranged on the upper part of the mounting wall 122, and a nut 123 fixed by welding is arranged on one side of the mounting wall 122, and the nut 123 corresponds to the positioning mounting hole 1221;

[0037] The edge of the bracket 12 is provided with a flange 125, and the angle between the flange 125 and the bracket 12 is 91°~95°.

[0038] The rear evaporator bracket 10 provided by the application is formed by bending and stretching the base plate 11 in a direction perpendicular to the base plate 11 to form the bracket 12, and then stretching the bracket 12 in a direction perpendicular to the mounting wall 122 of the bracket 12 to form the flange 125, so that the mounting wall 122 is located on one side of the bracket, the overall structure has a smaller volume and higher structural strength, and the positioning mounting hole 1221 can be directly formed on the mounting wall 122 during the punching process, which facilitates subsequent evaporator mounting and fixing. Since the included angle θ between the flange 125 and the mounting wall 122 of the bracket 12 is 91°-95°, the draft angle is set accordingly, and the upper end of the rear evaporator bracket 10 after forming is relatively narrow and has an open structure, which is beneficial for welding by welding equipment without the need to set a process gap. Therefore, the new rear evaporator bracket 10 of the application has higher structural strength than the current rear evaporator bracket 10, thereby solving the problems of low strength and high mold cost of the current rear evaporator bracket 10.

[0039] In order to make the technical solutions, objectives and advantages of the application more clear and explicit, the application will be described in detail below with reference to the drawings and examples. At the same time, in order to facilitate understanding, the rear evaporator bracket 10 will be used as a reference direction, and the base plate 11 of the rear evaporator bracket 10 will be set horizontally, and the direction perpendicular to the horizontal direction and away from the ground will be defined as upward, and vice versa.

[0040] The rear evaporator bracket 10 of the application is a relay connecting piece between the rear evaporator 20 and the lower vehicle body 30 in the vehicle air conditioning system, specifically the positioning mounting hole 1221 of the upper part of the bracket 12 connects the rear evaporator 20, and the base plate 11 is connected to the lower vehicle body 30, so the base plate 11 is the basic structural part of the rear evaporator bracket 10.

[0041] Figure 3 For a welding structure diagram of a rear evaporator bracket, please refer to Figure 2 and Figure 3 , the base plate 11 extends from one end of the arc-shaped connecting wall 121 away from the mounting wall 122 and forms the fixing part 111, and the fixing part 111 is welded and connected to the lower vehicle body 30 of the automobile.

[0042] In the above scheme, the substrate 11 is punched and formed by using a punching die, and the convex-shaped substrate 11 and the fixing portion 111 provided at the periphery thereof are beneficial to form a triangular welding fixing structure, which can not only ensure the connection strength of the substrate 11 and the lower vehicle body 30, but also adapt to various vehicle models due to the absence of a limiting structure, thereby increasing the application range.

[0043] The upper portion of the rear evaporator bracket 10 is a bracket 12, and the upper portion of the bracket 12 is connected with the rear evaporator 20, so that the installation function of the rear evaporator bracket 10 is concentrated on the bracket 12.

[0044] As shown in Figure 2 In order to make the rear evaporator bracket 10 have structural stability, in some embodiments, the bracket 12 is perpendicular to the substrate 11. The vertically connected bracket 12 and substrate 11 can improve the overall structural strength, and the vertical arrangement can also make the rear evaporator 20 maintain a substantially vertical state after being installed with the bracket 12, thereby better improving the installation stability of the rear evaporator 20 and the rear evaporator bracket 10 and improving the connection strength.

[0045] In some embodiments, the bracket 12 includes an arc-shaped connecting wall 121 and an installation wall 122 connected with each other. In order to fix the connected rear evaporator 20, the upper portion of the installation wall 122 is provided with at least two positioning installation holes 1221, one side of the installation wall 122 is provided with a welding fixed nut 123, and the nut 123 corresponds to the positioning installation hole 1221.

[0046] Specifically, the bracket 12 and the substrate 11 are an integral structural member, the bracket 12 is a bending structural member perpendicular to the substrate 11 formed by stamping and punching from the bottom of the substrate 11, that is, the arc-shaped connecting wall 121 and the installation wall 122 are formed in the punching process. The lower portion of the arc-shaped connecting wall 121 is adjacent to the fixing portion 111 of the substrate 11, and the upper portion of the arc-shaped connecting wall 121 is adjacent to the installation wall 122. The front surface of the integral installation wall 122 and the arc-shaped connecting wall 121 is a trapezoidal shape with a small upper portion and a large lower portion.

[0047] In order to maximize the resistance to the impact and vibration, the height of the installation wall 122 is 1 / 4~1 / 2 of the height of the bracket 12, so that the installation wall 122 forms an elastic space in combination with the arc-shaped connecting wall 121, which can reduce the cracking risk of the rear evaporator bracket 10 during stamping and can also enhance the stability of the substrate 11.

[0048] In some embodiments, as shown in Figure 2 The height of the installation wall 122 is 1 / 4~1 / 2 of the height of the bracket 12, and specifically can be 1 / 4, 3 / 8, 1 / 2 or any value therebetween, which is not limited herein.

[0049] In the above scheme, the substrate 11 is bent and extended during the punching process to form the vertical support 12, which further includes the mounting wall 122 and the arc-shaped connecting wall 121, and the arc-shaped connecting wall 121 connects the substrate 11 to the lower vehicle body 30, so that the substrate 11 and the support 12 have elasticity and can absorb impact.

[0050] Please continue to refer to Figure 2 , two circular positioning mounting holes 1221 are arranged at the upper part of the mounting wall 122, and a mounting nut 123 is correspondingly welded to at least one positioning mounting hole 1221. The positioning mounting hole 1221 should prevent burrs from appearing at the hole edge during the punching process, so as to facilitate the welding of the mounting nut 123 later. The welding process can use impact welding, argon arc welding or other welding methods, which are not limited here.

[0051] The substrate 11 and the support 12 after punching can be treated with a galvanized, oxidized or other surface rust-proof coating, which is not limited here.

[0052] In the above scheme, the positioning mounting hole 1221 arranged on the mounting wall 122 makes the punching direction consistent with the punching direction of the substrate 11 and the support 12, thereby reducing the complexity and development cost of the punching die.

[0053] In some embodiments, as shown in Figure 2 , in order to improve the strength of the support 12, the edge of the support 12 is provided with a flange 125, and the angle between the flange 125 and the support 12 is 91°~95°,

[0054] The connection between the two sides of the support 12 and the substrate 11 forms a reinforcing rib 126, which is an integral wedge-shaped structure with the support 12 and the substrate 11 being small at the top and large at the bottom. At the same time, in order to facilitate the punching forming, the connection between the reinforcing rib 126 and the substrate 11 is provided with a first connecting part 1251, which is a circular arc shape.

[0055] The angle θ between the flange 125 and the support 12 is 91°~95°, and can be 91°, 92°, 93°, 94°, 95° or any value between them, which is not limited here.

[0056] Specifically, please continue to refer to Figure 2 , the flange 125 is a folded edge structure arranged at the edge of the support 12 and protruding in the punching direction along the edge of the support 12. The protruding length of the flange 125 at the top end of the mounting wall 122 is shorter, and the flange 125 gradually extends from top to bottom along the top end of the mounting wall 122 until the side edge of the substrate 11 near the arc-shaped connecting wall 121.

[0057] The two sides of the bracket 12 are stretched along the punching direction to form the reinforcing rib 126 with the upper part smaller than the lower part from the arc-shaped connecting wall 121, and then the structure of the flange 125 at the upper part of the bracket 12 and the reinforcing rib 126 at the lower part are combined with the first connecting part 1251 and the second connecting part 1252 of the arc shape, so that the rear evaporator bracket 10 of the present application is stable in structure and forms the mounting groove 127.

[0058] The depth of the mounting groove 127 is 0.8-1.5 times the height of the nut 123. At the same time, in order to facilitate the welding of the nut 123, the vertical projection of the mounting wall 122 on the base plate 11 at least partially coincides with the side edge of the base plate 11.

[0059] Specifically, the depth of the mounting groove 127 is 0.8-1.5 times the height of the nut 123. Please continue to refer to Figure 2 , which can be 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5 or any value therebetween, which is not limited here.

[0060] Please continue to refer to Figure 2 , the side of the bracket 12 is the wedge-shaped structure with the upper part smaller than the lower part formed by the flange 125 and the reinforcing rib 126, which is similar to the shape of a duck's bill, and the open groove structure enclosed by the flange 125 and the reinforcing rib 126 can accommodate the nut 123, that is, the edge of the top of the mounting wall 122 is projected downward on the surface of the base plate 11 and adjacent to the edge of the mounting wall 122, and the mounting wall 122 occupies less space relative to the current rear evaporator bracket 10.

[0061] In order to facilitate the welding equipment to contact the nut 123, the depth of the mounting groove 127 is close to the height of the nut 123, and there is no need to process a process gap to avoid welding equipment.

[0062] Figure 4 It is a schematic view of a partial structure of a rear evaporator bracket, as Figure 4 shown, the reinforcing rib 126 is provided with a second connecting part 1252 at the connection with the bracket, and the included angle a between the reinforcing rib 126 and the edge of the second connecting part 1252 is 8°-15°, which can be 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15° or any value therebetween, which is not limited here.

[0063] In the above scheme, the flange 125 and the reinforcing rib 126 strengthen the strength of the bracket 12, and the shallow mounting groove 127 facilitates the welding, installation and disassembly of the nut 123 later.

[0064] The rear evaporator support 10 of this application can be formed by stamping from cold-rolled steel sheet. The thickness of the cold-rolled steel sheet is 1.0~2.0 mm, specifically 1.2, 1.4, 1.6, 1.8, 2.0 mm or any value between them, without limitation. The rear evaporator support 10 can also be formed by machining or die casting, without limitation. This application uses a thicker cold-rolled steel sheet to integrally stamp the support, which can improve the stability of the overall structure.

[0065] Figure 5 This is a schematic diagram of the installation structure of a rear-end evaporator bracket, as shown below. Figure 5 As shown, during the installation process, the rear evaporator bracket 10 is first welded to the lower body 30. Then, bolts and positioning pins are used to position and connect the bracket 12 and the lower part of the rear evaporator 20 through the rear evaporator bracket 10. Next, the upper part of the rear evaporator 20 is connected to the mounting position (not shown) near the D-pillar 50, thereby fixing the upper part of the rear evaporator 20 and completing the assembly of the rear evaporator 20.

[0066] In summary, the substrate 11 and bracket 12 of the rear evaporator bracket 10 of this application are structurally formed in the same punching process. Moreover, the two positioning mounting holes 1221 provided on the mounting wall 122 of the bracket 12 and the flange 125 on the edge of the bracket 12 are formed in one punching direction. That is, the outer shape punching and stretching, forward punching and flange structure are formed in one punching process. Since the new punching die adopts a forward punch and forward punching die structure, the cost of the new punching die is lower than that of the current die. In order to make the angle of the flange 125 and the mounting wall 122 of the bracket 12 91°~95°, the new punching die is set with a draft angle. In addition, the upper end of the formed rear evaporator bracket 10 is narrow, which is conducive to welding equipment and does not require the setting of process notch. Therefore, the structural strength of the rear evaporator bracket 10 of this application is higher than that of the current rear evaporator bracket 10 and it is an open structure, thereby solving the problems of high welding difficulty and low structural strength of the existing rear evaporator bracket structure.

[0067] 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 scope of protection of the present utility model.
