[0001] This utility model relates to the field of air conditioning technology, and in particular to a mounting clip for pre-fixing temperature sensors and a heating, ventilation and air conditioning system. Background Technology

[0002] To enhance the driving and riding experience of vehicles and other transportation tools, automotive heating, ventilation and air conditioning (HVAC) systems are equipped with temperature sensors at the air duct outlets to monitor the airflow temperature in the face and foot ducts and quickly adjust the temperature inside the cabin.

[0003] Existing HVAC systems mainly consist of a face temperature sensor, a foot temperature sensor, wiring harnesses, and a housing. The face and foot temperature sensors are each connected to the wiring harness. The drawbacks of this HVAC system include: the two temperature sensors are not connected to the housing; they are merely suspended from the wiring harnesses. This poses a risk of them falling off or being damaged during transportation, increasing costs and resulting in a high scrap rate. Utility Model Content

[0032] This embodiment discloses a mounting clip for pre-fixing a temperature sensor and a heating, ventilation, and air conditioning system including the mounting clip, such as... Figure 1 and Figure 2 As shown, the HVAC system includes a temperature sensor 100, a housing 200, and a wiring harness 300. The wiring harness 300 is connected to the temperature sensor 100, and the temperature sensor 100 is mounted on the housing 200 via mounting clips. The specific number of temperature sensors 100 is not limited; this embodiment includes two temperature sensors 100, namely a face temperature sensor and a foot temperature sensor, with the wiring harness 300 connected to both temperature sensors 100.

[0033] Install the clips to fix the temperature sensor 100 to the housing 200, ensuring that the temperature sensor 100 is in a stable state during product transportation and avoiding situations such as falling off or being damaged.

[0034] like Figures 3 to 5As shown, the mounting clip for pre-fixing the temperature sensor includes a clamping assembly, a limiting assembly, and a support rib 4 for abutting the temperature sensor 100 from the bottom. The clamping assembly includes two clamping members 1 arranged opposite each other, forming a space between the two clamping members 1 to accommodate the temperature sensor 100. The clamping members 1 have elastic deformation capability to change the distance between the two clamping members 1. The limiting assembly includes an end limiting member 2 and a bottom limiting member 3, forming a space between the end limiting member 2 and the bottom limiting member 3 to accommodate the temperature sensor 100.

[0035] During assembly, the temperature sensor 100 is aligned with the position between the two clamping parts 1 and pressed down, and the clamping parts 1 are pushed outward. The two clamping parts 1, which have a certain elastic deformation capacity, bend away from the temperature sensor 100. After the two clamping parts 1 are spread apart, the temperature sensor 100 is pressed down smoothly until it abuts against the support rib 4. The clamping parts 1 rebound moderately until they clamp or hold the temperature sensor 100, so that the temperature sensor 100 and the housing 200 form a stable connection relationship, which prevents the temperature sensor 100 from falling off or being damaged during transportation, thereby reducing the scrap rate and cost.

[0036] During disassembly, pull the temperature sensor 100 in the opposite direction. The two clamping parts 1 will be pushed apart to the sides until the temperature sensor 100 is completely removed, after which the two clamping parts 1 will spring back. The temperature sensor 100 is easy to disassemble and reassemble without the need for professional tools, providing a good user experience.

[0037] In the horizontal plane, two clamping members 1 are used to prevent the temperature sensor 100 from moving along the first direction, and the end limiting member 2 and the bottom limiting member 3 are used to prevent the temperature sensor 100 from moving along the second direction. The first direction and the second direction form a set angle. In this embodiment, the first direction is perpendicular to the second direction.

[0038] After assembly, the two clamping parts 1, the end limiting parts 2, and the bottom limiting parts 3 limit the temperature sensor 100 from different directions, ensuring that the temperature sensor 100 will not move accidentally in any direction, making the installation more stable and safer.

[0039] In order to prevent the temperature sensor 100 from falling out of the space between the clamping members 1, the clamping member 1 includes a columnar clamping body 11 and a clamping protrusion 12 disposed on the clamping body 11, with the clamping protrusion 12 of each clamping member 1 protruding toward the other clamping member 1.

[0040] The temperature sensor 100 has a groove on its side. During assembly, the temperature sensor 100 is pressed into the space between the two clamping parts 1. When the temperature sensor 100 comes into contact with the support rib 4, the clamping parts 1 spring back, and the clamping protrusion 12 is inserted into the groove of the temperature sensor 100, so that the two clamping parts 1 hold the temperature sensor 100 firmly and prevent the temperature sensor 100 from moving in the opposite direction.

[0041] The specific structure of the clamping protrusion 12 is not limited, as long as it can engage and limit the temperature sensor 100. In this embodiment, the clamping protrusion 12 is a wedge-shaped part lying on its side, with the longer straight edge connected to or integrally formed with the clamping body 11, and the shorter straight edge facing the temperature sensor 100. The two inclined sides of the wedge-shaped clamping protrusion 12 are driving surfaces 13. During installation, the bottom of the temperature sensor 100 abuts against the upper driving surface 13; during disassembly, the edge of the groove on the temperature sensor 100 abuts against the lower driving surface 13.

[0042] To prevent jamming, the drive surface 13 is an inclined or curved surface. When the temperature sensor 100 is installed or removed, a component of the pressure on the drive surface 13 can push the clamping body 11 to bend in the direction of the temperature sensor 100, that is, the clamping part 1 undergoes elastic deformation, leaving enough space for the installation and removal of the temperature sensor 100.

[0043] Based on the above structure, the clamping body 11 of each clamping member 1 is tilted towards the other clamping member 1, so that the clamping protrusion 12 can make more full contact with the groove of the temperature sensor 100, and the clamping member 1 can hold the temperature sensor 100 more firmly, so as to avoid the temperature sensor 100 from falling off or being damaged during transportation.

[0044] To reduce processing difficulty, the two clamping bodies 11 are tilted at the same angle. After installation, the pressure on both sides of the temperature sensor 100 is equal, making the position of the temperature sensor 100 more stable.

[0045] The specific structure of the end limiting member 2 and the bottom limiting member 3 is not limited, as long as they can limit the temperature sensor 100. In this embodiment, there is a height difference between the end limiting member 2 and the bottom limiting member 3; specifically, the end limiting member 2 is higher than the bottom limiting member 3. During installation, the temperature sensor 100 only needs to be aligned with the end limiting member 2 and pressed down, without needing to align with both the end limiting member 2 and the bottom limiting member 3 simultaneously, making installation more convenient.

[0046] To facilitate installation, the end limiting member 2 forms an end limiting slope 21 on the top side of the temperature sensor 100. During installation, the temperature sensor 100 does not need to be precisely aligned with the side of the end limiting member 2. As long as the temperature sensor 100 is within the range of the end limiting slope 21, it can slide in along the end limiting slope 21, resulting in high installation efficiency.

[0047] Based on the above structure, the end limiting member 2 includes a stepped structure. The stepped base surface 22 of the stepped structure is used to abut against the bottom surface of the temperature sensor 100, providing support for the temperature sensor 100 and improving the stability of the temperature sensor 100.

[0048] The specific structure and placement of the bottom limiting member 3 are not limited; they can be determined based on the shape of the bottom of the temperature sensor 100, as long as they can cooperate with the end limiting member 2 to limit the temperature sensor 100. In this embodiment, the bottom limiting member 3 forms a bottom limiting slope on its side facing the end limiting member 2. When the temperature sensor 100 deviates slightly from the ideal installation position, it can slide into the installation position along the bottom limiting slope as long as it is within the range of the bottom limiting slope, resulting in high installation efficiency.

[0049] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
