Description

Technical Field

[0001] This invention relates to the field of blower technology, and specifically to a novel blower without a negative electrode. Background Technology

[0002] With the steady growth of my country's economy and the continuous improvement of people's living standards and consumption levels, automobile use is becoming increasingly widespread, and car ownership is becoming more and more common. At the same time, people's demands for automotive driving comfort are also increasing. Automotive air conditioning systems (Heating, Ventilation, Air-conditioning and Cooling - HVAC) not only provide drivers and passengers with a superior comfortable environment but also improve work efficiency and safety. Therefore, the application of automotive air conditioning systems is becoming increasingly widespread.

[0003] The blower in an automotive air conditioning system typically consists of an electric motor and an impeller, and is rigidly connected. Installing the blower to the vehicle body is inconvenient due to limitations imposed by the motor's electrode terminals. Furthermore, the imbalance that occurs during blower rotation is unavoidable, leading to vibration and noise during operation. This can easily damage the electrode terminals, thus affecting the blower's lifespan. Simultaneously, this vibration and noise significantly impact passenger comfort. Therefore, improvements are necessary. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a novel blower without a negative terminal, which has the advantages of simplified installation and operation, improved working stability, and reduced vibration and noise.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a novel blower without a negative terminal, comprising: a mounting base; a motor body assembled on one side of the mounting base; an impeller disposed on the other side of the mounting base and fixedly assembled with the output shaft of the motor body; a positive terminal disposed on the mounting base and electrically connected to the positive terminal of the motor body; and a motor housing electrically connected to the negative terminal of the motor body.

[0006] In a further embodiment of the present invention, the edge of the mounting base is provided with a plurality of screw holes for assembly with the vehicle body.

[0007] In a further embodiment of the present invention, a mounting cavity for assembling the motor body is provided on the vehicle body; the inner wall of the mounting cavity is connected to the negative terminal of the vehicle body.

[0008] In a further embodiment of the present invention, the end of the motor housing away from the impeller is provided with a protrusion for abutting against the inner wall of the mounting cavity and for electrical connection with the negative electrode of the vehicle body.

[0009] In a further embodiment of the present invention, the inner wall of the mounting cavity is provided with a conductive spring sheet for the protrusion to abut against.

[0010] In a further embodiment of the present invention, the motor housing is made of metal.

[0011] In a further embodiment of the present invention, a shock-absorbing pad is provided on the side of the mounting base near the motor body.

[0012] In a further embodiment of the present invention, the operating voltage of the motor body is 12V.

[0013] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0014] This invention discloses a novel blower without a negative terminal. By connecting the negative terminal of the motor body to the motor housing and creating a mounting cavity in the vehicle body for assembling the motor body, the installation of this novel blower is simple: just place the motor body in the mounting cavity and then use locking bolts to fix the mounting base to the vehicle body. During installation, an electrical connection between the motor housing and the vehicle's negative terminal is achieved. Therefore, only the positive terminal needs to be connected before installation, simplifying the blower installation, removing the limitations of electrode terminals, enabling free connection, improving installation stability, reducing vibration and noise during operation, increasing the service life of the electrode terminals, and improving user comfort.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] This embodiment relates to a novel blower without negative terminals, such as... Figure 1-3 As shown, it includes: a mounting base 1; a motor body 2 mounted on one side of the mounting base 1; an impeller 3 located on the other side of the mounting base 1 and fixedly mounted to the output shaft of the motor body 2; a positive terminal 4 located on the mounting base 1 and electrically connected to the positive terminal of the motor body 2; and a motor housing 5 electrically connected to the negative terminal of the motor body 2. The motor housing 5 is made of metal and is used to complete the negative connection with the vehicle body during the installation of the blower, thereby removing the connection restrictions of the terminals, making the connection free, and improving the ease of installation.

[0026] The motor body 2 is mounted on the mounting base 1, and the output shaft of the motor body 2 passes through the middle of the mounting base 1, as shown below. Figure 2 As shown, the mounting base 1 has several screw holes 11 along its edge for assembly with the vehicle body, such as... Figure 3 As shown, the vehicle body has an installation cavity 01 for assembling the power supply body 2, and the inner wall of the installation cavity 01 is connected to the negative terminal of the vehicle body.

[0027] Therefore, when installing the blower, simply place the motor body 2 inside the mounting cavity 01 and then use several locking bolts to fix it to the vehicle body through the screw holes 11 on the mounting base 1. In this embodiment, the mounting base 1 is provided with a shock-absorbing pad 03 on the side close to the motor body 2. The shock-absorbing pad 03 can improve the installation stability of the blower, thereby improving the vibration generated by the motor body 2 during rotation.

[0028] It should be noted that the size of the mounting cavity 01 matches the size of the motor body 2. Therefore, during the structural installation of the blower, one end of the motor housing 5 is already in contact with the inner wall of the mounting cavity 01, thus achieving the negative terminal connection between the vehicle body and the motor housing 5. Therefore, in this embodiment, the operation of connecting the motor body 2 to the vehicle body negative terminal is integrated into the blower's structural installation operation. Compared to the traditional positive and negative terminal connection method, this embodiment simplifies the blower's installation process, effectively improves the blower's installation efficiency, and avoids damage to the negative terminal during use, thereby increasing the overall service life of the blower. The motor body 2 operates at 12V, ensuring electrical safety.

[0029] like Figure 3 As shown, the end of the motor housing 5 furthest from the impeller 3 has a protrusion 21 for abutting against the inner wall of the mounting cavity 01 and electrically connecting to the negative terminal of the vehicle body. The inner wall of the mounting cavity 01 has a conductive spring piece 02 for the protrusion 21 to abut against. The protrusion 21 is used to better abut against the inner wall of the mounting cavity 01 to achieve a stable electrical connection with the negative terminal of the vehicle body. While achieving stable electrical contact with the protrusion 21, the conductive spring piece 02 also plays a shock-absorbing and buffering role between the motor body 2 and the vehicle body, further preventing the vibration generated by the motor body 2 during rotation from affecting the comfort of the users inside the vehicle.

[0030] The working principle of this invention is roughly as follows: By connecting the negative terminal of the motor body 2 to the motor housing 5 and creating an installation cavity 01 on the vehicle body to power the assembly of the motor body 2, when installing this new type of blower, it is only necessary to place the motor body 2 in the installation cavity 01 and then use locking bolts to fix the mounting base 1 to the vehicle body. During installation, an electrical connection can be achieved between the motor housing 5 and the negative terminal of the vehicle. Therefore, only the positive terminal 4 needs to be connected before installation, thus simplifying the installation of the blower, removing the limitations of the electrode terminals, achieving free connection, improving installation stability, reducing vibration and noise during operation, increasing the service life of the electrode terminals, and improving user comfort.

[0031] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
