Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to an easy-to-install installation structure for an automotive air conditioning speed control resistor. Background Technology

[0002] In the automotive air conditioning industry, most speed control modules and speed control resistors are fixed to the housing by two screws and two quick-release nuts. During production, workers need to assemble two quick-release nuts and screw in two screws to complete the assembly of a speed control module (or speed control resistor).

[0003] A search revealed Chinese Patent Publication No. CN213534387U, which discloses a blower speed control resistor assembly structure applied in the field of automotive HVAC assembly components. The assembly structure features a mounting slot on its mounting housing, a limiting groove on the inner edge of the mounting slot, positioning holes on the mounting housing, a protruding positioning protrusion on the speed control resistor body, and a mounting plate on the speed control resistor body with protruding limiting protrusions on its side. This blower speed control resistor assembly structure is simple in structure, allowing for convenient and quick connection and disassembly of the mounting housing and the speed control resistor body. It provides both fastening and positioning functions during connection, and requires only light force for disassembly, facilitating reuse and extending service life.

[0004] The aforementioned device uses the cooperation of the limiting protrusion and the groove to fix the speed regulating resistor; however, during the long-term operation of the car, its installation structure is prone to problems such as structural aging, loosening, or poor contact. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-install installation structure for an automotive air conditioning speed control resistor, aiming to improve the existing technology which is prone to structural aging, loosening, or poor contact during long-term operation of the vehicle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an easy-to-install automotive air conditioning speed control resistor installation structure, including a vehicle body, a fixed bracket fixedly connected to the inner side of the vehicle body, a quick-locking mechanism provided on the side of the fixed bracket away from the vehicle body, a speed control resistor module provided on the side of the quick-locking mechanism away from the fixed bracket, heat dissipation fins provided on both sides of the speed control resistor module, and an external interface provided on one side of the speed control resistor module.

[0007] The above technical solution addresses the issues of structural aging, loosening, or poor contact that often occur during long-term vehicle operation. These issues arise from the quick disassembly and installation of the two structures in the quick-locking mechanism, the external interface on the speed control resistor module enabling it to perform its speed control function, and the improved heat dissipation efficiency of the speed control resistor module through heat sinks.

[0008] As a further description of the above technical solution:

[0009] The quick-locking mechanism includes two symmetrically connected housings. The opposite sides of the two housings are fixedly connected to a fixed bracket and a speed-regulating resistor module, respectively. Each of the two housings has a chamber on its opposite side. A rectangular hole is formed on one side of each housing, communicating with the chamber. A guide block is provided inside the housing. One side of the guide block is fixedly connected to the inner wall of the chamber, and a locking tongue is provided on the other side of the guide block. A through hole is formed on one side of the guide block, and an actuating component is provided inside the through hole. One end of the actuating component is fixedly connected to the locking tongue, and the other end of the actuating component passes through the rectangular hole. The side of the guide block away from the housing is arc-shaped, and the locking tongue is hemispherical.

[0010] Through the above technical solution, by using the action of the actuating component, the mutual cooperation of the rectangular hole, through hole one, locking tongue, and guide block, and by the design of the arc shape of the guide block and the hemispherical shape of the locking tongue, the quick locking mechanism can be conveniently installed and quickly disassembled.

[0011] As a further description of the above technical solution:

[0012] The actuation assembly includes a lever and a spring. The outer wall of the lever and the inner wall of the housing are both fixedly connected to fixing blocks. The two ends of the spring are respectively connected to the two fixing blocks. The outer wall of the lever passes through a rectangular hole and a through hole. One end of the lever is fixedly connected to the latch, and the other end of the lever is located outside the housing.

[0013] The above technical solution provides support for the fixing block through the housing and lever, and the interaction between the lever and the spring helps to achieve the functions of convenient installation and quick disassembly of the quick locking mechanism.

[0014] As a further description of the above technical solution:

[0015] A lock box is fixedly connected to the other side of the guide block. The lock box is hemispherical in shape. The lock tongue is located on the side of the lock box away from the guide block. One side of the spherical outer wall of the lock box is fixedly connected to the other side of the guide block. The through hole is opened on the other side of the spherical outer wall of the lock box.

[0016] The above technical solution provides space through the chamber, supports the lock box through the guide block, and reduces the space occupied by the lock box through the hemispherical shape of the lock box, thus avoiding interference with the movement of the spring.

[0017] As a further description of the above technical solution:

[0018] The housing has a guide plate inside, which is fixedly connected to the side wall of the chamber. One side of the guide plate is fixedly connected to the outer wall of the lock box, and one side of the lock box is flush with the other side of the lock box.

[0019] The above technical solution provides support for the guide plate through the housing and improves the stability of the lock box through the fixed connection between the guide plate and the lock box.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the latch is provided with a slide rail, and a slide groove matching the slide rail is opened on one side of the lock box.

[0022] The above technical solution, through the cooperation of the slide rail and the lock box slide groove, guides the bolt as it slides on the lock box, thereby improving the stability of the installation structure.

[0023] As a further description of the above technical solution:

[0024] A connecting bolt is provided on one side of the fixed bracket, and one end of the connecting bolt is threaded to the inside of the vehicle body.

[0025] The above technical solution, through the threaded connection between the connecting bolts and the vehicle body, not only improves the stability of the fixed bracket, but also helps to increase the flexibility of the speed control resistor installation.

[0026] As a further description of the above technical solution:

[0027] A limiting plate is fixedly connected to the outer wall of the other end of the lever, and one side of the limiting plate is in contact with the outer wall of the housing.

[0028] The above technical solution reduces the range of motion of the lever and improves the stability of the structure by fitting the limiting plate to the outer wall of the housing.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the vehicle body provides stable support for the fixed bracket. The quick-locking mechanism is separated by the quick disassembly and installation of the two structures in the quick-locking mechanism, so that the fixed bracket is separated from the speed-regulating resistor module. The speed-regulating resistor module can perform its speed-regulating function through the external interface on the speed-regulating resistor module. The heat dissipation efficiency of the speed-regulating resistor module is improved by the heat dissipation fins. This improves the situation in the prior art where the structure is prone to aging, loosening or poor contact during the long-term operation of the car.

[0031] 2. In this utility model, the sliding of the locking tongue is achieved through the lever, rectangular hole, through hole one, fixing block and spring, and the quick locking mechanism is conveniently installed and quickly disassembled through the cooperation of the housing, guide block and lock box.

[0040] 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.

[0041] Reference Figure 1 An embodiment of this utility model provides an easy-to-install automotive air conditioning speed control resistor installation structure, including a vehicle body 1, a fixed bracket 2 fixedly connected to the inner side of the vehicle body 1, a quick-locking mechanism 4 provided on the side of the fixed bracket 2 away from the vehicle body 1, a speed control resistor module 6 provided on the side of the quick-locking mechanism 4 away from the fixed bracket 2, heat dissipation fins 5 provided on both sides of the speed control resistor module 6, and an external interface 7 provided on one side of the speed control resistor module 6.

[0042] In this embodiment, Figure 4 The vehicle body 1 provides stable support for the fixed bracket 2. The quick-locking mechanism 4 consists of two structures, which are connected to the fixed bracket 2 and the speed control resistor module 6 respectively, thus supporting the speed control resistor module 6. When installing or removing the car air conditioning speed control resistor, the quick-locking mechanism 4 can be separated by quickly disassembling and installing the two structures in the quick-locking mechanism 4, so that the fixed bracket 2 and the speed control resistor module 6 are separated. The side of the new speed control resistor module 6 with the quick-locking mechanism 4 is aligned and connected with the quick-locking mechanism 4 on the fixed bracket 2, thus completing the replacement of the speed control resistor module 6. Through the external interface 7 on the speed control resistor module 6, the speed control resistor module 6 can perform its speed control function, and the heat dissipation efficiency of the speed control resistor module 6 is improved by the heat dissipation fins 5, thereby improving the existing technology that is prone to structural aging, loosening or poor contact during long-term operation of the car.

[0043] Reference Figure 1 , Figure 2 and Figure 4The quick-locking mechanism 4 includes two symmetrically connected housings 40. The opposite sides of the two housings 40 are fixedly connected to the fixed bracket 2 and the speed regulating resistor module 6, respectively. Each of the two housings 40 has a cavity 46 on its opposite side. A rectangular hole 42 is opened on one side of the housing 40, which communicates with the cavity 46. A guide block 44 is provided inside the housing 40. One side of the guide block 44 is fixedly connected to the inner wall of the cavity 46. A locking tongue 43 is provided on the other side of the guide block 44. A through hole 47 is opened on one side of the guide block 44. An actuating component 41 is provided inside the through hole 47. One end of the actuating component 41 is fixedly connected to the locking tongue 43, and the other end of the actuating component 41 passes through the rectangular hole 42. The side of the guide block 44 away from the housing 40 is arc-shaped, and the locking tongue 43 is hemispherical.

[0044] Specifically, the left housing 40 is supported by the fixed bracket 2. The outer wall of the actuating component 41 can move left and right inside the rectangular hole 42 and the through hole 47. The fixed connection between one end of the actuating component 41 and the latch 43, and the hemispherical design of the latch 43, allow the latch 43 to slide on the guide block 44, thereby causing the latch 43 to shift in a direction. This causes the left side of the latch 43 inside the left housing 40 to tilt upwards, and the right side of the latch 43 inside the right housing 40 to tilt downwards. This is the initial state before installation.

[0045] When the two housings 40 are installed together, the right housing 40 is slid towards the left housing 40. Through the arc-shaped design of one side of the guide block 44 and the alignment of the guide block 44 by the chamber 46, the arc-shaped sides of the two guide blocks 44 move towards each other. Through the interference between the arc-shaped side of the guide block 44 and the side of the latch 43, the guide block 44 gradually flattens the raised part of the latch 43 as the two housings 40 are continuously tightened, and finally makes one side of the two latches 43 fit together, so that the two latches 43 form a sphere. At this time, under the action of the actuating component 41, the two latches 43 are simultaneously offset, so that the left latch 43 interferes with the right guide block 44, and the right latch 43 interferes with the left guide block 44. Under the action of the actuating component 41, the two housings 40 are locked.

[0046] When it is necessary to release the lock of the quick-locking mechanism 4, the two toggle components 41 are moved towards each other by moving the two locking tongues 43, so that the flat side of the locking tongue 43 is flush with one side of the guide block 44. Then the right housing 40 is pulled out to complete the release of the lock, thereby realizing the quick-locking and unlocking function of the quick-locking mechanism 4.

[0047] Reference Figure 2 , Figure 3 and Figure 4The actuating assembly 41 includes a lever 410 and a spring 411. The outer wall of the lever 410 and the inner wall of the housing 40 are both fixedly connected to fixing blocks 412. The two ends of the spring 411 are respectively connected to the two fixing blocks 412. The outer wall of the lever 410 passes through the rectangular hole 42 and the through hole 47. One end of the lever 410 is fixedly connected to the locking tongue 43, and the other end of the lever 410 is located outside the housing 40.

[0048] Specifically, the housing 40 and the lever 410 support the fixing block 412. When the quick locking mechanism 4 is in a separated or installed state, the spring 411 is slightly tightened. Through the rectangular hole 42 and the through hole 47, the spring 411 pulls the lever 410 tight. Then, the movement of the lever 410 drives the bolt 43 to rotate, causing one side of the bolt 43 to lift up. When it is necessary to unlock, by moving one side of the lever 410, the lever 410 moves, gradually stretching the spring 411. The rectangular hole 42 and the through hole 47 provide the range of movement for the lever 410, so that the bolt 43 rotates to be flush with the guide block 44. At this time, the bolt 43 no longer interferes with the guide block 44, and the housing 40 is pulled out, thus completing the unlocking of the fixing bracket 2.

[0049] Reference Figure 2 , Figure 3 and Figure 4 A lock box 45 is fixedly connected to the other side of the guide block 44. The lock box 45 is hemispherical in shape. The lock tongue 43 is located on the side of the lock box 45 away from the guide block 44. One side of the spherical outer wall of the lock box 45 is fixedly connected to the other side of the guide block 44. A through hole 47 is opened on the other side of the spherical outer wall of the lock box 45.

[0050] Specifically, the chamber 46 provides space, the guide block 44 provides support for the lock box 45, the through hole 47 provides space for the locking tongue 43 to slide and provides support for the through hole 47, and the hemispherical shape of the lock box 45 reduces the space occupied in the chamber 46, avoids interference with the fixing block 412 during the extension process, and thus avoids affecting the function of the structure.

[0051] Reference Figure 3 and Figure 4 Inside the housing 40, there is a guide plate 48, which is fixedly connected to the side wall of the chamber 46. One side of the guide plate 48 is fixedly connected to the outer wall of the lock box 45, and one side of the lock box 45 is flush with the other side of the lock box 45.

[0052] Specifically, the housing 40 provides support for the guide plate 48, the chamber 46 provides space for the guide plate 48, and the guide plate 48 is fixedly connected to the lock box 45, thereby improving the stability of the lock box 45. The design of one side of the lock box 45 being flush with the other side provides redundant guidance for the guide block 44, which helps to improve the accuracy of the docking of the two housings 40.

[0053] Reference Figure 3 , Figure 4 and Figure 6 The outer wall of the lock tongue 43 is provided with a slide rail 9, and a slide groove matching the slide rail 9 is opened on one side of the lock box 45.

[0054] Specifically, when the latch 43 slides in the lock box 45, the cooperation between the slide rail 9 and the slide groove on the lock box 45 limits the direction of the sliding of the latch 43, and ensures that when the quick locking mechanism 4 is separated, the latch 43 will not slide out of the lock box 45, thereby helping to improve the stability of the latch 43 when it slides.

[0055] Reference Figure 1 A connecting bolt 3 is provided on one side of the fixed bracket 2, and one end of the connecting bolt 3 is threaded to the inside of the vehicle body 1.

[0056] Specifically, the connection between the fixed bracket 2 and the vehicle body 1 is achieved through the threaded connection of the connecting bolt 3 and the vehicle body 1, and the fixed bracket 2 and the vehicle body 1 can be disassembled, thereby helping to improve the flexibility of the speed control resistor installation.

[0057] Reference Figure 2 , Figure 3 and Figure 4 The other end of the lever 410 is fixedly connected to a limiting plate 8, and one side of the limiting plate 8 is in contact with the outer wall of the housing 40.

[0058] Specifically, by fitting one side of the limiting plate 8 to the outer wall of the housing 40, the outer wall of the housing 40 interferes with the limiting plate 8, which in turn interferes with the lever 410, thereby helping to improve the accuracy and stability of locking and unlocking the lever 410.

[0059] Working principle: When disassembling the car air conditioning speed control resistor, the lever 410 is moved, causing the lever 410 to move between the rectangular hole 42 and the through hole 47, and the spring 411 is gradually stretched, which causes the locking tongue 43 to rotate until it is flush with the guide block 44. At this time, the locking tongue 43 no longer interferes with the guide block 44, and the housing 40 is pulled out, thus completing the unlocking of the fixed bracket 2.

[0060] At this time, the lever 410 is released, and under the contraction of the fixing block 412, the lever 410 moves and is limited by the limiting plate 8, causing one side of the locking tongue 43 to be raised. When installing or removing the car air conditioning speed control resistor, the right housing 40 slides to the left housing 40, and the arc-shaped sides of the two guide blocks 44 move towards each other. Through the interference between the arc-shaped side of the guide block 44 and one side of the locking tongue 43, the two housings 40 are continuously tightened, and the guide block 44 gradually flattens the raised part of the locking tongue 43, and finally makes one side of the two locking tongues 43 fit together, so that the two locking tongues 43 form a sphere. At this time, under the action of the toggle component 41, the two locking tongues 43 are simultaneously offset, causing the left locking tongue 43 to interfere with the right guide block 44, and the right locking tongue 43 to interfere with the left guide block 44. Under the action of the toggle component 41, the two housings 40 are locked, thereby improving the situation where the existing technology is prone to structural aging, loosening or poor contact during the long-term movement of the car.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
