The assembly path of the heater water pipe is usually perpendicular to the direction of the heater water pipe. However, when space is limited, the heater water pipe is installed from the bottom and the direction is consistent with the assembly path. This makes it impossible to achieve the original heater water pipe pressure plate fixing solution.

[0003] Chinese patent CN202120589125.8 discloses an installation structure for a car air conditioning heater hose, including a main structure of a pressure plate assembly for fixing the heater hose and a sealing sponge. The solution is that the heater hose passes through the water pipe hole inside the pressure plate assembly, and the sealing sponge is attached to the pressure plate assembly to restrict the movement of the heater hose, so as to achieve sealing and stability.

[0004] The above-mentioned technical solution has a simple structure for installing and fixing the heating water pipes, but it cannot be assembled in situations where space is limited, and the heating water pipes are not easy to fix. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an assembly and fixing structure for automotive air conditioning heating water pipes, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model discloses an assembly and fixing structure for automotive air conditioning heater hoses. The technical solution includes a blower housing and a heater hose. The heater hose is installed along the blower housing from bottom to top. The heater hose is wrapped with a water pipe sealing sponge. The blower housing is provided with a pipe fixing mechanism, which includes a first pressure plate and a second pressure plate. The first pressure plate and the second pressure plate are detachably connected and have a self-locking mechanism between them. A water pipe guide groove is opened inside the second pressure plate, and a water pipe outlet is opened on the surface of the second pressure plate. The water pipe outlet is connected to the water pipe guide groove.

[0007] As a preferred technical solution of this utility model, the self-locking mechanism includes a rotation limiting pin, a guide pin and a fixing buckle on the side of the second pressure plate, and a fixing hole is opened in the middle of the fixing buckle and the second pressure plate.

[0008] As a preferred technical solution of this utility model, the self-locking mechanism further includes a limiting pin groove, a guide slot, and a snap-fit ​​position. The limiting pin groove, guide slot, and snap-fit ​​position correspond one-to-one with the positions of the rotating limiting pin, guide pin, and fixed snap-fit. The limiting pin groove, guide slot, rotating limiting pin, and guide pin are all arc-shaped structures.

[0009] As a preferred technical solution of this utility model, the second pressure plate is connected to the first pressure plate and the blower housing through the first fixing bolt, the second fixing bolt and the fixing hole.

[0010] As a preferred technical solution of this utility model, the water pipe guide groove is provided with a limiting protrusion.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model fixes the pipe fixing mechanism to the side of the blower housing, and opens a pipe guide groove inside the pipe fixing mechanism for the heating water pipe to pass through and be fixed, so as to fix the heating water pipe when the space at the bottom of the blower housing is limited. By setting a self-locking mechanism between the first pressure plate and the second pressure plate, the initial fixing can be achieved before the bolt fixing is used. The air conditioner assembly can be completed smoothly even when the space is limited, ensuring that the heating water pipe is installed in the correct position, while ensuring its reliability and stability.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figures 1 to 7 As shown, this utility model discloses an assembly and fixing structure for automotive air conditioning heater hoses. The technical solution includes a blower housing 1 and a heater hose 2. The heater hose 2 is installed along the blower housing 1 from bottom to top. A hose sealing sponge 5 is wrapped around the heater hose 2. A pipe fixing mechanism 6 is provided on the blower housing 1. The pipe fixing mechanism 6 includes a first pressure plate 3 and a second pressure plate 4. The first pressure plate 3 and the second pressure plate 4 are detachably connected and have a self-locking mechanism between them. The self-locking mechanism includes a rotation limit pin 401 and a guide pin 402 on the same side of the second pressure plate 4. The fixing buckle 403 has a fixing hole in the middle of the second pressure plate 4. The self-locking mechanism also includes a limiting pin groove 301, a guide slot 302, and a buckle position 303 on the same side of the first pressure plate 3. The limiting pin groove 301, guide slot 302, and buckle position 303 correspond one-to-one with the positions of the rotating limiting pin 401, guide pin 402, and fixing buckle 403. The limiting pin groove 301, guide slot 302, rotating limiting pin 401, and guide pin 402 are all arc-shaped structures. The second pressure plate 4 is connected by the rotating limiting pin 401, guide pin 402, and fixing buckle 403. The buckle 403 engages with the limiting pin groove 301, guide slot 302, and buckle position 303 of the first pressure plate 3. The distance between the fixed buckle 403 and the rotating limiting pin 401 is slightly smaller than the distance between the buckle position 303 and the limiting pin groove 301, so that the second pressure plate 4 can be firmly engaged with the first pressure plate 3. The upper buckle position 303 and the fixed buckle 403 interact to prevent the upper end from falling off, and the arc-shaped structure of the lower limiting pin groove 301 and the rotating limiting pin 401 interacts to prevent the lower end from falling off, thus achieving self-locking. The second pressure plate 4 is secured by the first fixing bolt 4. 04. The second fixing bolt 405 and fixing hole 409 are connected to the first pressure plate 3 and the blower housing 1 for further fixing. The second pressure plate 4 has a water pipe guide groove 406 inside and a water pipe outlet 408 on its surface. The water pipe outlet 408 is connected to the water pipe guide groove 406. The warm air water pipe 2 is fully surrounded and fixed through the water pipe guide groove 406 and extends out from the water pipe outlet 408. The water pipe guide groove 406 has a limiting protrusion 407 inside. The limiting protrusion 407 squeezes the water pipe sealing sponge 5 to achieve further fixing and anti-slip.

[0016] The working principle of this utility model is as follows: First, the heating water pipe 2 is wrapped with a water pipe sealing sponge 5. The heating water pipe 2 extends from the bottom of the blower housing 1 to the first pressure plate 3. Then, the heating water pipe 2 is inserted into the water pipe guide groove 406 of the second pressure plate 4 and extends out from the water pipe outlet 408. Then, the rotation limit pin 401, guide pin 402 and fixing buckle 403 of the second pressure plate 4 are inserted into the limit pin groove 301, guide slot 302 and buckle position 303 of the first pressure plate 3. The second pressure plate 4 is fixed to the first pressure plate 3 using the first fixing bolt 404, and the second fixing bolt 405 is used to fix the second pressure plate 4 to the blower housing 1, thereby fixing the heating water pipe 2. The limit protrusion 407 inside the water pipe guide groove 406 and the water pipe sealing sponge 5 squeeze each other to further fix the heating water pipe 2, and can effectively isolate vibration and prevent abnormal noise.
