Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle air conditioning accessories technology, and in particular to a self-positioning press-fit anti-shaking device for the resistor of an automotive air conditioning blower. Background Technology
[0002] In automotive air conditioning systems, the blower resistor is a key component for controlling the blower speed and regulating the air conditioning's cooling and heating capabilities. By changing the resistance value, the current flowing through the blower is limited, allowing for control of different blower speeds. This, in turn, meets the flexible adjustment needs of drivers and passengers based on ambient temperature and personal comfort. Simultaneously, it also protects the blower from overload damage, ensuring the normal operation of the air conditioning system.
[0003] However, in practical applications, to ensure stable performance of the blower resistor, the resistor hole size is usually smaller than the resistor itself to ensure a secure fixation within the mounting hole. This design, however, leads to difficulties in resistor assembly. For example, improper assembly can cause unstable current, resulting in blower vibration, or even blower malfunctions such as failure to operate, abnormal noise, or slow operation. These issues severely impact the normal operation of the blower and the effectiveness and safety of the automotive air conditioning system. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a self-positioning press-fit anti-shake device for automotive air conditioning blower resistors, so that the resistor can be firmly installed in the resistor hole and the resistor can be used normally.
[0005] To achieve the above objectives, this utility model provides the following solution: a self-positioning and press-fitting anti-shake device for an automotive air conditioning blower resistor, comprising: a positioning unit, a pressing unit, a reset unit, and a support unit; the positioning unit, pressing unit, and reset unit are respectively mounted on the support unit; the positioning unit is used to position the resistor installation position; the pressing unit is used to press the resistor; the reset unit is used to reset the support unit after pressing; the support unit is used to ensure the overall stability.
[0006] Preferably, the support unit includes a rotating head and a handle, with the rotating head rotatably mounted at the intersection of the two handles, and the two handles reciprocating through the rotating head.
[0007] Preferably, a reset unit is installed between the two handles. The reset unit includes a spring, with both ends of the spring fixedly installed on the inner sides of the two handles to support the two handles to return to their original positions after pressing.
[0008] Preferably, the positioning unit includes a fixing post, which is mounted on the handle. The other end of the fixing post, which is mounted opposite to the handle, has an anti-slip structure to increase friction with the product.
[0009] Preferably, the anti-slip structure is a positioning groove, which matches the outer contour of the product to form a snap-fit fit for positioning.

[0020] 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.
[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] Example 1
[0023] like Figure 1-2 As shown, this utility model provides a self-positioning press-fit anti-shake device for an automotive air conditioning blower resistor, comprising: a positioning unit, a pressing unit, a reset unit, and a support unit; the positioning unit, pressing unit, and reset unit are respectively mounted on the support unit, the positioning unit is used to position the resistor installation position; the pressing unit is used to press the resistor; the reset unit is used to reset the support unit after pressing; the support unit is used to ensure the overall stability.
[0024] The support unit includes a rotating head 3 and handles 4. The rotating head 3 is rotatably mounted at the intersection of the two handles 4, and the two handles 4 reciprocate through the rotating head 3. As the main operating mechanism of the entire device, it ensures the overall stability and rigidity during operation and effectively transmits the user's force.
[0025] A reset unit is installed between the two handles 4. The reset unit includes a spring 5, with both ends of the spring 5 fixedly installed inside the two handles 4. This spring 5 is used to support the two handles 4 to return to their original positions after pressing. By cooperating with the swing handles 4 and the spring 5, the two handles 4 can automatically return to their original positions after pressing, reducing manual operation and improving pressing efficiency.
[0026] The positioning unit includes a fixing post 1, which is mounted on a handle 4. The other end of the fixing post 1, opposite the handle 4, has an anti-slip structure to increase friction with the product. This anti-slip structure is a positioning groove that matches the product's outline to form a snap-fit, increasing friction between the fixing post 1 and the product. This effectively prevents the product from sliding or shifting during positioning. Furthermore, the contour matching ensures geometric positioning of the product, guaranteeing its installation position. Simultaneously, the edges of the positioning groove feature a rounded transition design, preventing scratches or damage to the product surface. This ensures stable positioning while protecting the product's appearance.
[0027] The pressing unit includes a pressing block 2, which is fixedly installed on the side of another handle 4 opposite to the positioning unit, for installing the resistor into the resistor hole. The working surface of the pressing block 2 adopts a flat and smooth surface treatment process to ensure that pressure can be applied evenly during pressing, so that the resistor can enter the resistor hole smoothly.
[0028] Both the positioning unit and the pressing unit are made of elastic materials, such as rubber and elastic plastic, to mitigate the impact during the pressing process and prevent excessive impact from damaging the resistor or the mounting part.
[0029] Working principle: During use, the operator fixes the fixing post 1 to the product according to the resistor installation position to form a snap-fit, and fixes the pressing block 2 in the resistor position. Then, the operator holds the handle 4, and the handle 4 applies a downward force to the resistor through the rotating head 3, so that the resistor enters the resistor hole. After pressing is completed, the operator releases the handle 4, and the spring 5 of the reset unit will support the two handles 4 to return to their original position for the next operation.
[0030] Therefore, by adopting the above-mentioned self-positioning press-fit anti-shake device for automotive air conditioning blower resistors, the resistors can be firmly installed in the resistor holes, ensuring normal use of the resistors.
[0031] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
