Detailed Description

The following discloses embodiments or examples of various implementations of the subject technology. Specific examples of components and arrangements are described below to simplify the present disclosure, but these are merely examples and are not intended to limit the scope of the present invention. For example, a first feature described later in the specification may be distributed over a second feature and may include embodiments in which the first and second features are distributed in direct association, or may include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be directly associated with each other. Additionally, reference numerals and/or letters may be repeated among the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. Further, when a first element is described as being coupled or coupled to a second element, the description includes embodiments in which the first and second elements are directly coupled or coupled to each other, as well as embodiments in which one or more additional intervening elements are added to indirectly couple or couple the first and second elements to each other.

It should be noted that fig. 1 to 9 are only examples, are not drawn to scale, and should not be taken as limiting the scope of the invention.

The automobile air conditioner assembly comprises a ventilation device, an evaporator, a warm air heat exchanger and the like. The ventilating device comprises a shell and a fan, the evaporator and the warm air heat exchanger can be arranged in an air duct inside the shell, the fan is used for enabling air flow to enter the air duct inside the shell and flow through the evaporator or the warm air heat exchanger, therefore the air flow is cooled or heated, then under the action of the fan, the cooled or heated air flow is sent into a compartment, and therefore personnel in the compartment can obtain a comfortable environment.

The vehicle air conditioning assembly also includes various lines for constituting a cooling circuit, a heating circuit, etc. of the air conditioning system. To secure these lines, the automotive air conditioning assembly also includes a tube clamp assembly for clamping and securing the lines. The line may be a high pressure refrigerant line or a low pressure refrigerant line. Furthermore, the pipeline may also be solid.

Figures 1 and 2 show a clamp assembly according to a comparative example. The clamp assembly includes a bendable tube clip 80 and a fastener (not shown). Both ends of the pipe clamping piece 80 are respectively provided with a first fixing hole 80a and a second fixing hole 80 b. The pipe clip 80 may be folded in half from the middle portion so that the first fixing hole 80a and the second fixing hole 80b are aligned and form a structure for accommodating the pipeline 81. Fasteners, such as bolts, may be passed through the first and

second fixing holes

80a and 80b to fix the pipe clip 80 to the frame of the vehicle air conditioning assembly. The line 81 includes a relatively coarse line 81a and a relatively fine line 81 b. The thicker line 81a may be a low-pressure refrigerant pipe and the thinner line 81b may be a high-pressure refrigerant pipe.

In the comparative example described above, the pipe clamp piece 80 needs to be bent to be folded in two to clamp the pipe line 81, and when the pipe clamp piece 80 needs to be detached from the pipe line 81, the pipe clamp piece 80 needs to be deformed in the opening direction. As can be seen, the assembly and disassembly processes of the pipe clamp assemblies of the comparative examples are complicated. In addition, the positions of the first fixing hole 80a and the second fixing hole 80b are also easily deviated, so that the fastener cannot pass through the first fixing hole 80a and the second fixing hole 80 b.

Fig. 3 shows an embodiment of the invention. The pipe clamp assembly 90 comprises a main clamping piece 1 and an auxiliary clamping piece 2; wherein the main clip 1 is provided to be detachably connected with the sub clip 2 to clip the pipeline 91. Since the pipe clamp assembly 90 clamps the pipeline 91 by detachably coupling the main jaw 1 and the sub jaw 2, convenience in detachment and installation of the pipe clamp assembly 90 is improved. The line 91 includes a relatively coarse line 91a and a relatively fine line 91 b. The thicker line 91a may be a low-pressure refrigerant pipe and the thinner line 91b may be a high-pressure refrigerant pipe. In this embodiment, the detachably connectable connection may be a snap connection or may be connected by a detachable fastening assembly.

Referring to fig. 3, 4 and 5, in a specific embodiment, the main clip 1 has a first main connecting portion 11, a main clamping portion 10 and a second main connecting portion 12, the main clamping portion 10 being located between the first main connecting portion 11 and the second main connecting portion 12 in a length direction of the main clip 1; the sub clip 2 has a first sub connection portion 21, a sub clamping portion 20, and a second sub connection portion 22, the sub clamping portion 20 being located between the first sub connection portion 21 and the second sub connection portion 22 in the length direction of the sub clip 2; wherein the first main connection part 11 is arranged to be detachably connected with the first auxiliary connection part 21 and/or the second main connection part 12 is arranged to be detachably connected with the second auxiliary connection part 22, such that the main clamping part 10 and the auxiliary clamping part 20 together clamp the pipeline 91. This solution allows the pipeline 91 to be clamped in the middle of the main clamp 1 and the sub clamp 2, which helps to make the pipe clamp assembly 90 compact and form a stable clamp for the pipeline 91.

With continued reference to fig. 3, 4, 5, the first primary connection 11 has a connection section 111 and an extension section 112; the connecting section 111 connects the main clamping part 10 and the extension section 112; the connecting section 111 is detachably connected to the first sub-connecting portion 21, and the extending section 112 has a fixing hole 112 a. The securing holes 112a are used to secure the tube clamp assembly 90 to the frame of the vehicle air conditioning assembly. This embodiment allows the fixing hole 112a to be formed only in the extension 112, thereby solving the problem of deviation of the fixing hole in the comparative example.

As shown in fig. 6, 7, 8 and 9, in a more specific embodiment, the pipe clamp assembly 90 further includes a fastening assembly 3, the first main connecting portion 11 and the first auxiliary connecting portion 21 are detachably connected by the fastening assembly 3, and more specifically, the connecting section 111 and the first auxiliary connecting portion 21 are clamped by the fastening assembly 3. In fig. 3 and 4, the second main connecting portion 12 and the second sub-connecting portion 22 are detachably connected by the fastening assembly 3. The fastening assembly 3 may be a bolt assembly including a bolt, a nut, and a washer.

With continued reference to fig. 6, 7, 8, 9, the second primary connection 12 snaps into engagement with the second secondary connection 22. In fig. 3 and 4, the first main connecting portion 11 is engaged with the first sub-connecting portion 21.

Referring to fig. 4, the first sub connecting portion 21 has a latch 2a, and the connecting section 111 of the first main connecting portion 11 has a latch hole 1 a; referring to fig. 6 and 8, the second sub connection portion 22 has a latch 2a, and the second main connection portion 12 has a latch hole 1 a. The latch 2a is configured to be inserted into the latch hole 1a to be latched with the latch hole 1 a. More specifically, the latch 2a is curved, and the latch 2a inserted into the latching hole 1a can abut against the inner surface of the latching hole 1a to prevent the latch 2a from being removed from the latching hole 1 a.

The width of the latch hole 1a is larger than the thickness of the latch 2a, which enables the latch 2a to move relative to the latch hole 1a in the width direction of the latch hole 1a when the fastening assembly 3 is removed during the process of disassembling the pipe clamp assembly 90, thereby allowing the latch 2a to be easily removed from the latch hole 1 a.
