Description

Technical Field

[0001] This utility model relates to the field of resistor assembly structure technology, and in particular to a speed regulating resistor assembly structure for a blower. Background Technology

[0002] In automotive HVAC assemblies, components such as blower speed control resistors or modules are mounted on the housing. These resistors or modules, by changing their resistance values, can easily and reliably regulate the current applied to the blower circuit, enabling different blower speeds and thus different air intake speeds for the HVAC assembly. In existing technology, these speed control resistors or modules are primarily fastened to the plastic housing of the HVAC assembly with screws. However, this screw-based connection, after repeated disassembly and reassembly, can cause deformation and damage to the screw holes, affecting the connection's effectiveness.

[0003] An existing patent (publication number: CN213534387U) discloses a blower speed-regulating resistor assembly structure. This structure is simple and allows for convenient and quick connection and disassembly of the mounting housing and the speed-regulating resistor body. It provides both fastening and positioning during connection, and disassembly requires only light force, facilitating reuse and extending service life. However, in implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] The solution replaces the threaded pins with a snap-fit ​​structure. However, during use, the resistor itself is subjected to vibrations from the car, which makes the snap-fit ​​structure prone to loosening, resulting in unstable fixation. Secondly, the resistor itself will dissipate heat during use, and the heat will accumulate on top of the resistor, thus limiting the resistor's lifespan. Summary of the Invention

[0005] To address the aforementioned issues of vibration causing the locking structure to loosen and heat buildup affecting service life, this invention provides a blower speed control resistor assembly structure.

[0006] This utility model provides a blower speed control resistor assembly structure, which adopts the following technical solution:

[0007] A speed-regulating resistor assembly structure for a blower includes a mounting housing, a connecting block connected to the top of the mounting housing, threaded blocks connected to both sides of the connecting block, a first damping block connected to the bottom of the threaded block, a needle-shaped block connected to the top of the first damping block, a first rubber layer connected to the inner side of the first damping block, and a resistor body connected inside the first rubber layer.

[0008] A maze passage is provided below the first shock absorber block, a first conical block is provided above the maze passage, a second conical block is provided below the first shock absorber block, and a second shock absorber block is connected below the second conical block.

[0009] The above technical solution facilitates the use of the first and second shock absorbers to form a labyrinthine shock-absorbing and buffering structure, thereby achieving rapid shock absorption and buffering. In addition, multiple needle-shaped blocks are set on the top to achieve rapid heat dissipation and prevent heat from accumulating on the top.

[0010] Optionally, in the above-mentioned blower speed control resistor assembly structure, the mounting housing is provided with threaded grooves around its perimeter, and a threaded sleeve is connected inside the threaded grooves, and the threaded sleeve and the threaded block are connected by a threaded connection.

[0011] The above technical solution facilitates the use of threaded sleeves to prevent damage to threaded blocks during use, ensuring long-term use.

[0012] Optionally, in the above-mentioned blower speed control resistor assembly structure, the first damping block is also provided with threaded grooves and threaded sleeves around its perimeter. The first damping block forms a threaded connection structure with the threaded block through the threaded grooves, and the connection method between the threaded block and the connecting block is a threaded connection.

[0013] The above technical solution facilitates the quick installation of the first damping block by cooperating with the threaded block, ensuring the fixed installation of the first damping block and the mounting housing.

[0014] Optionally, in the above-mentioned blower speed regulating resistor assembly structure, the needle-shaped blocks are evenly and equidistantly distributed above the first damping block, the needle-shaped blocks and the first damping block are interlocked, and the needle-shaped blocks are evenly and equidistantly distributed around the resistor body.

[0015] The above technical solution facilitates rapid heat dissipation by cooperating with the first shock-absorbing block using the needle-shaped block, and also makes it easy to disassemble and replace the needle-shaped block.

[0016] Optionally, in the above-mentioned blower speed control resistor assembly structure, the labyrinth channel is divided into upper and lower sides, and the labyrinth channel is evenly and equidistantly distributed below the first damping block and above the second damping block, respectively, and a second rubber layer is symmetrically distributed on both sides of the labyrinth channel.

[0017] The above technical solution facilitates the absorption of energy generated by vibrations through the maze-like passages, achieving the purpose of shock absorption and buffering.

[0018] Optionally, in the above-mentioned blower speed control resistor assembly structure, the first conical block is evenly and equidistantly distributed below the first damping block, the first conical block and the second conical block are staggered, and the second conical block is evenly and equidistantly distributed above the second damping block.

[0019] The above technical solution facilitates the use of the first and second conical blocks to dissipate the energy generated by vibration and improve the shock absorption effect.

[0020] Optionally, in the above-mentioned blower speed control resistor assembly structure, the size and structure of the second damping block are consistent with the size and structure of the first damping block, the second damping block is tightly attached to the first rubber layer, and the first rubber layer and the resistor body are installed as an integral unit.

[0021] The above technical solution facilitates the stabilization of the gap between the second damping block and the resistor body through the first rubber layer, preventing dust and other contaminants from entering the interior.

[0022] In summary, this utility model has at least one of the following beneficial effects:

[0023] By setting a first damping block and a second damping block around the resistor body to cooperate with each other, and merging them in the center to form an "S" shaped labyrinth channel, the labyrinth channel absorbs the vibration when the resistor body vibrates, and performs damping and buffering work. At the same time, a first cone block and a second cone block with a cone structure are set inside the labyrinth channel to consume the vibration secondaryly and ensure the damping effect.

[0024] By setting multiple needle-shaped blocks above the first damping block and distributing them around the resistor body, the needle-shaped blocks dissipate the heat inside the resistor body and accelerate the dissipation of surrounding heat. At the same time, because of their snap-fit ​​structure, the needle-shaped blocks can be quickly disassembled to ensure replacement and improve the adaptability of use. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0031] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 This utility model provides an embodiment of a blower speed control resistor assembly structure, including a mounting housing 1, a connecting block 6 connected to the top of the mounting housing 1, threaded blocks 7 connected to both sides of the connecting block 6, and a first shock absorber 2 connected to the bottom of the threaded blocks 7. The mounting housing 1 has threaded grooves around its perimeter, and threaded sleeves are connected inside the threaded grooves. The threaded sleeves are connected to the threaded blocks 7 by a threaded connection. The threaded sleeves prevent damage to the threaded blocks 7 during use, ensuring long-term use. The first shock absorber 2 also has threaded grooves and threaded sleeves around its perimeter. The first shock absorber 2 forms a threaded connection structure with the threaded blocks 7 through the threaded grooves. The threaded blocks 7 are connected to the connecting block 6 by a threaded connection. Through the cooperation of the first shock absorber 2 and the threaded blocks 7, the first shock absorber 2 can be quickly installed, ensuring the fixed installation of the first shock absorber 2 and the mounting housing 1.

[0032] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 A needle-shaped block 3 is connected above the first damping block 2. A first rubber layer 5 is connected to the inner side of the first damping block 2. A resistor body 4 is connected inside the first rubber layer 5. The needle-shaped blocks 3 are evenly and equidistantly distributed above the first damping block 2. The needle-shaped blocks 3 and the first damping block 2 have an interlocking structure. The needle-shaped blocks 3 are evenly and equidistantly distributed around the resistor body 4. Through the cooperation between the needle-shaped blocks 3 and the first damping block 2, heat dissipation is achieved quickly, and the needle-shaped blocks 3 are easy to disassemble and replace.

[0033] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4A maze channel 8 is provided below the first damping block 2, a first conical block 9 is provided above the maze channel 8, a second conical block 10 is provided below the first damping block 2, and a second damping block 12 is connected below the second conical block 10. The maze channel 8 is divided into upper and lower sides, which are evenly and equidistantly distributed below the first damping block 2 and above the second damping block 12, respectively. Second rubber layers 11 are symmetrically distributed on both sides of the maze channel 8. The maze channel 8 absorbs the energy generated by vibration, achieving the purpose of shock absorption and buffering. The first conical block 9 is evenly and equidistantly distributed on the first damping block 2. Below, the first conical block 9 and the second conical block 10 are arranged in an alternating structure. The second conical block 10 is evenly and equidistantly distributed above the second damping block 12. The first conical block 9 and the second conical block 10 cooperate to consume the energy generated by vibration and improve the damping effect. The size and structure of the second damping block 12 are the same as those of the first damping block 2. The second damping block 12 is tightly attached to the first rubber layer 5. The first rubber layer 5 and the resistor body 4 are installed as an integral unit. The first rubber layer 5 stabilizes the gap between the second damping block 12 and the resistor body 4 and prevents dust and other particles from entering the interior.

[0034] Working principle: When in use, firstly, during operation, the heat emitted by the resistor body 4 will be absorbed by the needle block 3 and then released through the top of the needle block 3, so that the needle block 3 acts as a heat dissipation fin. At the same time, the needle block 3 itself is a small needle-shaped structure, which will not affect the airflow above and will not affect the heat dissipation effect. If the needle block 3 is damaged, it can be replaced separately.

[0035] As mentioned above, during use, if the resistor body 4 is about to vibrate, it will transmit the vibration to the first damping block 2 and the second damping block 12. The vibration then enters the labyrinth channel 8. The S-shaped labyrinth channel 8 provides initial damping and buffering for the vibration. Then, the first conical block 9 and the second conical block 10 provide secondary damping and buffering for the vibration to ensure the damping effect. After long-term use, the threaded block 7 can be removed to disassemble the first damping block 2 and the second damping block 12 for inspection. At the same time, when the threads are worn, the threaded sleeve or the threaded block 7 can be replaced.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
