[0002] Most existing automotive air conditioning system pipe fixings use metal brackets, which require the use of bolts and nuts. These brackets are not lightweight enough, and the assembly is difficult and costly. In addition, there are some plastic pipe clamps, but the barbs or snap-fit ​​parts of these clamps are easily damaged during assembly, and they are difficult to disassemble after assembly, making them unusable for repeated use. Utility Model Content

[0003] This application aims to solve the problem in related technologies where vehicle air conditioning pipe fixing devices are difficult to disassemble after assembly and cannot be reused repeatedly. Therefore, this utility model proposes a vehicle air conditioning pipe fixing device.

[0004] In a first aspect, embodiments of this application provide a vehicle air conditioning pipe fixing device, including:

[0005] Card slot panel, wherein the side surface of the card slot panel is provided with an elastic sheet extending obliquely downward;

[0006] A pipe fixing bracket is disposed on the top surface of the card holder panel, and the pipe fixing bracket is configured to clamp and fix the air conditioning pipe;

[0007] A retaining post is disposed on the surface of the retaining panel opposite to the pipe fixing bracket. The retaining post has a hollow cavity and an elastic barb on its side surface. A portion of the elastic end of the elastic barb protrudes from the outer contour of the retaining post along the central axis. When the elastic end is squeezed, the elastic end contracts into the hollow cavity.

[0008] In some embodiments, the elastic sheet includes at least a first elastic sheet and a second elastic sheet mirror-disposed on two opposite sides of the card holder panel, with one end of the first elastic sheet and the second elastic sheet extending obliquely downward away from the card holder panel.

[0009] In some embodiments, the plane containing the first elastic sheet and the plane containing the second elastic sheet extend and intersect.

[0010] In some embodiments, when the elastic barb engages with the component to be connected, at least a portion of the surface of the elastic sheet abuts against at least a portion of the surface of the component to be connected.

[0011] In some embodiments, the elastic barb includes at least a first elastic barb and a second elastic barb spaced apart on the side surface of the retaining post, wherein the first elastic barb and the second elastic barb are equidistant from the lower end face of the retaining post.

[0012] In some embodiments, the first elastic barb and the second elastic barb are mirror images disposed on the side surface of the locking post.

[0013] In some embodiments, the surface of the card holder panel is provided with a reinforcing rib extending one end to the outer surface of the pipe fixing bracket, and the reinforcing rib is cross-shaped.

[0014] In some embodiments, the pipe fixing bracket includes:

[0015] A clamping part having an air conditioning pipe receiving cavity, wherein a notch communicating with the receiving cavity is provided on one side of the clamping part;

[0016] The guide portion, the two guide portions are respectively disposed on the clamping portion near the end of the notch, and the guide portion extends in a direction away from the notch.

[0018] Thirdly, embodiments of this application also provide a vehicle, the vehicle including the vehicle air conditioning system as described in the above embodiments.

[0019] Compared with the prior art, the technical solutions provided by the above embodiments of this application have at least the following beneficial effects:

[0020] 1) The vehicle air conditioning pipe fixing device provided in this application has an elastic piece extending downwards on the side surface of the mounting plate, and pipe fixing brackets and locking posts respectively provided on the upper and lower surfaces of the mounting plate. The side surface of the locking post is provided with an elastic barb and an internal hollow cavity. During the installation process, the locking post is inserted into the mounting hole of the vehicle body sheet metal. The mounting hole and the locking post are of similar size. During the insertion process, the elastic barb retracts into the hollow cavity. After insertion, the elastic end of the elastic barb engages with the back of the vehicle body sheet metal. At the same time, the elastic piece abuts against and squeezes the front of the vehicle body sheet metal. Thus, the installation is more convenient. In addition, during the disassembly and assembly process, it is only necessary to press the elastic barb on the back of the vehicle body sheet metal. Due to the elasticity of the elastic piece, the elastic force of the elastic piece will push the locking post out of the vehicle body sheet metal. The air conditioning pipe can also be directly pulled out from the pipe fixing bracket. It is easy to disassemble and can be reused.

[0021] 2) By setting a reinforcing rib on the surface of the card seat panel that extends to the outer surface of the pipe fixing bracket, the reinforcing rib is cross-shaped, which improves the structural stability of the device connection.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0039] Please see Figure 1 and Figure 2 This embodiment provides a vehicle air conditioning pipe fixing device 10. This fixing device 10 is preferably used for vehicle air conditioning system pipes. However, the application scenarios of the fixing device 10 also include, but are not limited to, fixing air conditioning system pipes in shipping and maritime vehicles. The fixing device 10 will be described in detail below using the fixing of pipes in a vehicle air conditioning system as an example. The fixing device 10 may include a mounting plate 100, a pipe fixing bracket 200, and a locking post 300. The side surface of the mounting plate 100 is provided with a downwardly extending... An elastic sheet 110 extends; a pipe fixing bracket 200 is disposed on the top surface of the mounting plate 100, and the pipe fixing bracket 200 is configured to clamp and fix the air conditioning pipe; a clamping post 300 is disposed on the surface of the mounting plate 100 opposite to the pipe fixing bracket 200, the clamping post 300 has a hollow cavity 310 inside and an elastic barb 320 is provided on the side surface, a portion of the elastic end of the elastic barb 320 protrudes out of the outer contour of the clamping post 300 along the central axis, wherein, when the elastic end is squeezed, the elastic end contracts toward the hollow cavity 310.

[0040] Thus, by providing an elastic sheet 110 extending downwards on the side surface of the card holder panel 100, and a pipe fixing bracket 200 and a locking post 300 respectively provided on the upper and lower surfaces of the card holder panel 100, wherein the side surface of the locking post 300 is provided with an elastic barb 320 and an inner hollow cavity 310, during the installation process, the locking post 300 is inserted into the corresponding mounting hole of the vehicle body sheet metal. The mounting hole is about the same size as the locking post 300. During the insertion process, the elastic barb 320 retracts into the hollow cavity 310. After insertion, the elastic end of the elastic barb 320 engages with the back of the vehicle body sheet metal. At the same time, the elastic sheet 110 abuts against and presses the front of the vehicle body sheet metal, so that the fixing device 10 can be installed more firmly. The installation process does not require additional tools and is more convenient.

[0041] Furthermore, during the disassembly and assembly process, simply press the elastic barb 320 on the back of the body sheet metal. Due to the elasticity of the elastic plate 110, the elastic force of the elastic plate 100 will push the locking post 300 out of the body sheet metal. The air conditioning pipe can also be directly pulled out from the pipe fixing bracket 200. Disassembly is convenient and it can be reused.

[0042] It should be noted that in this embodiment, the fixing device 10 can be made of plastic material, which is lighter than using a metal bracket. The card seat panel 100 enhances the structural stability of the device. The pipe fixing bracket 200 can selectively engage and fix the air conditioning pipe. The clamping post 300 is used to fix the fixing device 10 to the body sheet metal. The card seat panel 100, the pipe fixing bracket 200 and the clamping post 300 can be integrally molded, which facilitates production and reduces production costs.

[0043] Optionally, the surface of the card holder panel 100 is provided with a reinforcing rib 120 extending to the outer surface of the pipe fixing bracket 200. The reinforcing rib 120 is cross-shaped. By setting the reinforcing rib 120, the structural stability of the connection of the fixing device 10 is improved. In particular, since the pipe fixing bracket 200 needs to fix the air conditioning system pipes, and the pipes usually twist, the setting of the reinforcing rib 120 can further improve the structural strength of the pipe fixing bracket 200.

[0044] Please see Figure 2 and Figure 4 The elastic piece 110 includes at least a first elastic piece 111 and a second elastic piece 112 mirror-displayed on two opposite sides of the card holder panel 100. One end of the first elastic piece 111 and the second elastic piece 112 extends obliquely downward away from the card holder panel 100. The arrangement of the two elastic pieces can provide a more uniform elastic force during the disassembly and assembly process, thereby popping the card post 300 out of the body sheet metal to complete the disassembly and assembly.

[0045] Optionally, the plane where the first elastic piece 111 is located and the plane where the second elastic piece 112 is located extend to intersect to form an angle α. The angle α is preferably 30° to 170°. For example, the angle between the planes where the first elastic piece 111 and the second elastic piece 112 are symmetrically arranged on two opposite sides of the card seat panel 100 can be 110°. Furthermore, a protrusion is provided at the ends of the first elastic piece 111 and the second elastic piece 112 away from the card seat panel 100. Since the ends of the elastic pieces 110 need to come into contact and rub against the body sheet metal parts multiple times during the repeated installation process, the protrusion can increase the structural strength of the ends of the elastic pieces 110.

[0046] Of course, the number of elastic sheets 110 can also be set to other quantities, such as one, three or even four. The specific choice can be made according to actual needs. Among them, it is preferred to set two symmetrically.

[0047] In some embodiments, combined with Figure 2 and Figure 4 For the pipe fixing bracket 200, the pipe fixing bracket 200 may include a clamping part 210 having an air conditioning pipe receiving cavity and a guide part 220. The clamping part 210 has a notch 211 communicating with the receiving cavity on one side. The two guide parts 220 are respectively disposed on the clamping part 210 near the end of the notch 211, and the guide parts 220 extend in the direction away from the notch 211.

[0048] Thus, with the clamping part 210 provided, the air conditioning pipe receiving cavity of the clamping part 210 extends through both ends, so that the air conditioning pipe can be wrapped, clamped and fixed. The notch 211 and the guide part 220 are provided to facilitate pressing the air conditioning pipe into the receiving cavity of the clamping part 210.

[0049] Optionally, the two guide portions 220 can be symmetrically arranged about the cross section AA in the figure. The planes on which the two guide portions 220 are located extend and intersect to form an included angle β. The angle range of the included angle β can be from 10° to less than 180°. Preferably, the included angle β formed by the planes on which the two guide portions 220 are located can be 60°. In this way, during installation, the arrangement of the guide portions 220 can more conveniently guide the air conditioning pipe into the receiving cavity of the clamping portion 210.

[0050] Optionally, the shape of the pipe receiving cavity of the clamping part 210 can adopt a "C" shape design consistent with the pipe shape, that is, a circular shape with a notch. In order to make the clamping part 210 clamp the air conditioning pipe more firmly, the diameter of the receiving cavity can be slightly smaller than the outer diameter of the corresponding air conditioning pipe.

[0051] It should be noted that the clamping part 210 and the guide part 220 are integrally formed. For the notch 211, the shortest distance between the two side walls of the notch 211 needs to be less than the diameter of the receiving cavity, so as to achieve a firm clamping of the air conditioning pipe.

[0052] Please see Figure 2 , Figure 3 and Figure 5 The hollow cavity 310 is opened along the central axis from one end of the locking post 300. The hollow cavity 310 reduces the weight of the device and facilitates the retraction of the elastic barb 320. The elastic barb 320 includes at least a first elastic barb 321 and a second elastic barb 322 spaced apart on the side surface of the locking post 300. The first elastic barb 321 and the second elastic barb 322 are equidistant from the lower end face of the locking post 300. The arrangement of the first elastic barb 321 and the second elastic barb 322 makes the locking post 300 more securely engaged with the body sheet metal.

[0053] In some embodiments, the first elastic barb 321 and the second elastic barb 322 are mirror images of each other on the side surface of the retaining post 300. The elastic ends of the first elastic barb 321 and the second elastic barb 322 protrude from the outer contour of the retaining post 300 projected along the central axis. By mirroring the images, when disassembling the body sheet metal of the mounting and fixing device 10, it is only necessary to manually apply relative squeezing force to make the first elastic barb 321 and the second elastic barb 322 retract into the hollow cavity 310, thus making it easier to disassemble the fixing device 10.

[0054] In some embodiments, when the elastic barb 320 engages with the part to be connected, at least a portion of the surface of the elastic piece 110 abuts against at least a portion of the surface of the part to be connected. Taking a car body sheet metal as an example, when the elastic barb 320 engages with the car body sheet metal, at least a portion of the surface of the elastic piece 110 abuts against at least a portion of the surface of the car body sheet metal. In this way, on the one hand, the connection between the fixing device 10 and the car body sheet metal is more secure, and on the other hand, it is more convenient to disassemble and assemble.

[0055] Of course, it should be noted that there needs to be a height difference between the lowest position of the elastic plate 110 and the upper surface of the elastic barb 320. This height difference needs to be less than the thickness of the body sheet metal. For example, when the thickness of the body sheet metal is 2.5mm, the height difference between the lowest position of the elastic plate 110 and the upper surface of the elastic barb 320 can be 1mm. This ensures that after the fixing device 10 is installed, the elastic plate 110 will compress the outer surface of the body sheet metal to accumulate elastic potential energy. This ensures that after the circular locking post 300 is inserted into the circular hole of the body sheet metal, the elastic plate 110 of the mounting bracket will generate an upward elastic force between itself and the front of the body sheet metal, causing the circular locking post 300 to move upward along the circular hole of the body sheet metal. At the same time, the elastic barbs 320 on both sides of the circular locking post 300 will press against the back of the body sheet metal to prevent the circular locking post 300 from moving upward. The interaction of the elastic forces between the two ensures that the entire fixing device 10 can be firmly locked onto the body sheet metal without loosening, achieving the effect of connection and fixation.

[0056] It is understood that the fixing device 10 in the above embodiment does not require special assembly tools and can be operated by hand, providing flexible operation space. In particular, the design of the elastic hook 320 makes the overall assembly and disassembly of the plastic clip very convenient. During assembly, the pipe is first inserted into the pipe receiving cavity of the pipe fixing bracket 200, and then the locking post 300 is directly inserted into the round hole of the body sheet metal. The elastic hook 320 is automatically pressed into the round locking post 300 as the round locking post is inserted. After passing through the round hole of the body sheet metal, it will automatically spring back and press against the back of the body sheet metal for automatic fixing, without any other operation. If disassembly is required, simply press the elastic hook 320 into the round locking post 300 from the back of the body sheet metal. The elastic force of the elastic piece 110 of the locking seat will then pop the fixing device 10 out of the body sheet metal, and the air conditioning pipe can also be directly pulled out from the pipe fixing bracket 200.
