Description

Technical Field

[0001] This utility model relates to the field of automotive fan motor technology, and in particular to an automotive fan motor with a protective housing. Background Technology

[0002] The automotive fan motor is a key component of the automotive cooling system, primarily providing auxiliary heat dissipation for the engine or air conditioning system. It is compatible with different engine displacements and types of vehicles, and can adjust its speed according to the vehicle's operating status. When the engine temperature is too high, the fan starts to accelerate heat dissipation, and when the air conditioning is on, it works with the condenser to improve cooling efficiency. During operation, it needs to be linked with the vehicle control system to ensure that it works at the appropriate time. It has the ability to adapt to the complex operating conditions of the vehicle, and can withstand certain vibrations, temperature changes, and the influence of external impurities. It provides temperature protection for the stable operation of various vehicle systems and is an important component for maintaining normal vehicle operation and a comfortable in-vehicle environment.

[0003] In the field of automotive fan motors, the installation and removal of traditional protective housings rely heavily on a large number of bolts or clips. During installation, each bolt must be tightened individually or multiple clips must be aligned, which is cumbersome and time-consuming. During disassembly and maintenance, tools are needed to loosen them one by one. Especially in the confined space of a car engine compartment, this not only increases the workload of maintenance personnel, but may also cause wear on connecting parts due to repeated operations, affecting the sealing and stability of the protective housing. It is difficult to meet the requirements of efficient disassembly and long-term reliable use. Therefore, there is a need for an automotive fan motor with a protective housing. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an automotive fan motor with a protective shell, which can solve the problem that the traditional protective shell relies on a large number of bolts or clips for disassembly and assembly, resulting in cumbersome operation, time and labor, and difficulty in maintenance in a small space, which can easily cause component wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive fan motor with a protective shell, comprising a protective shell and a convenient disassembly and assembly mechanism. The convenient disassembly and assembly mechanism includes a base plate, a rotating plate, limiting side plates, a clamping plate, a threaded rod, and a knob. The base plate is slidably connected to the bottom of the protective shell, the rotating plate is rotatably connected to the outer surface of the base plate, multiple limiting side plates are fixedly connected to the surface of the rotating plate, the clamping plate is slidably connected to the opposite surfaces of two limiting side plates, the end of the clamping plate near the rotating plate is in contact with the rotating plate, the threaded rod is threadedly connected to the inside of the rotating plate, the knob is fixedly connected to the threaded rod, the clamping plate is threadedly sleeved on the outer surface of the threaded rod, and the clamping plate is slidably connected to the protective shell.

[0006] Preferably, the number of the convenient assembly and disassembly mechanisms is multiple and they are fixedly connected to the outer surface of the base plate at equal intervals in a circumferential array.

[0007] Preferably, the top of the base plate is fixedly connected with multiple heat dissipation structures at equal intervals in a circumferential array, and a sealing gasket is fixedly connected to the top of the base plate. The sealing gasket is in contact with the bottom of the protective shell, and threaded holes are opened on the surface of the base plate.

[0008] Preferably, the heat dissipation structure can be a rectangular heat sink.

[0009] Preferably, the heat dissipation structure can be a serrated heat sink.

[0010] Preferably, the surface of the protective shell is provided with multiple limiting grooves adapted to the heat dissipation structure, and the heat dissipation structure is slidably connected to the limiting grooves.

[0011] Preferably, the outer surface of the protective shell has multiple vents at equal intervals, and each vent is fixedly connected to a dustproof net.

[0012] Preferably, multiple activated carbon moisture-absorbing boxes are fixedly connected at equal intervals on the outer surface of the protective shell.

[0013] Preferably, the top of the protective housing is bolted to a top cover, and the surface of the top cover has an opening and a rotor opening, with a motor rotor installed inside the rotor opening.

[0014] Preferably, the top of the protective shell is fixedly connected with a plurality of limiting plates for limiting the position of the top cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The automotive fan motor with a protective shell achieves initial positioning through the sliding connection between the base plate and the protective shell. The rotating plate can flexibly adjust its angle to adapt to different installation positions. The limiting side plate guides and constrains the clamping plate, ensuring its sliding trajectory is stable. The cooperation between the threaded rod and the knob achieves precise displacement of the clamping plate, making the clamping plate and the protective shell easy to engage or disengage without complicated tools. Multiple mechanisms arranged in a circumferential array can evenly distribute the connection stress, improve the overall connection strength, and facilitate the quick installation and disassembly of the protective shell, reducing operation steps and time costs. Moreover, the structure is compact, occupies little space, and is suitable for narrow installation environments, which helps to improve the maintenance efficiency and reliability of the automotive fan motor.

[0024] Please see Figure 1-4This utility model provides a technical solution: an automotive fan motor with a protective shell, including a protective shell 1 and a convenient disassembly and assembly mechanism. The convenient disassembly and assembly mechanism includes a base plate 9, a rotating plate 10, limiting side plates 11, a locking plate 12, a threaded rod 13, and a knob 14. The base plate 9 is slidably connected to the bottom of the protective shell 1. The rotating plate 10 is rotatably connected to the outer surface of the base plate 9. There are multiple limiting side plates 11, all of which are fixedly connected to the surface of the rotating plate 10. The locking plate 12 is slidably connected to the opposite surfaces of two limiting side plates 11. One end of the locking plate 12 near the rotating plate 10 is in contact with the rotating plate 10. The threaded rod 13 is threadedly connected to the inside of the rotating plate 10. The knob 14 is fixedly connected to the threaded rod 13. The locking plate 12 is threadedly sleeved on the outer surface of the threaded rod 13. The locking plate 12 is slidably connected to the protective shell 1.

[0025] Multiple easy-to-assemble and disassemble mechanisms are equidistantly fixed to the outer surface of the base plate 9 in a circumferential array. Multiple heat dissipation structures 15 are equidistantly fixed to the top of the base plate 9 in a circumferential array. A sealing gasket 17 is fixedly connected to the top of the base plate 9, and the sealing gasket 17 contacts the bottom of the protective shell 1. Threaded holes 16 are provided on the surface of the base plate 9. The heat dissipation structure 15 can be a rectangular heat sink or a serrated heat sink. Multiple limiting grooves 18 adapted to the heat dissipation structure 15 are provided on the surface of the protective shell 1. The protective housing 1 is slidably connected to the limiting slide groove 18. Multiple ventilation openings 7 are equidistantly provided on the outer surface of the protective housing 1. Each ventilation opening 7 is fixedly connected to a dustproof net 8. Multiple activated carbon moisture-absorbing boxes 6 are fixedly connected to the outer surface of the protective housing 1 at equal intervals. The top of the protective housing 1 is bolted to a top cover 2. The surface of the top cover 2 is respectively provided with an opening 4 and a rotor opening 5. The inside of the rotor opening 5 is a motor rotor 19 (the motor body connected to it is installed inside the protective housing 1). Multiple limiting plates 3 for limiting the top cover 2 are fixedly connected to the top of the protective housing 1.

[0026] The protective outer shell 1 serves as the core load-bearing structure. The top is connected to the top cover 2 by bolts, and the bottom is slidably fitted to the base plate 9. Ventilation openings 7 are opened on the outer surface and dustproof nets 8 are fixed thereon. Activated carbon moisture-absorbing boxes 6 are also installed. Limiting grooves 18 are opened on the inner side to match the heat dissipation structure 15, providing comprehensive protection for the internal motor.

[0027] The top cover 2 is made of lightweight alloy material. During installation, it is precisely positioned by the limiting plate 3 on the top of the protective shell 1. The opening 4 on the surface facilitates the operation of the motor components, and the rotor opening 5 provides running space for the motor rotor, which reduces the overall weight and ensures the normal operation of the motor.

[0028] The limiting plate 3 and the protective shell 1 are integrally formed from the same metal material and are evenly distributed around the top edge of the protective shell 1. During the installation of the top cover 2, it plays a guiding and limiting role to prevent the top cover 2 from shifting and causing poor sealing, thus ensuring the connection and sealing between the protective shell 1 and the top cover 2.

[0029] Ventilation openings 7 are evenly distributed on the side of the protective shell 1. Each ventilation opening 7 has a fine metal dustproof mesh 8 fixed inside. The ventilation openings 7 allow air circulation inside and outside the protective shell 1 to help dissipate heat. The dustproof mesh 8 effectively blocks external dust from entering the motor and reduces the impact of dust on the motor.

[0030] The activated carbon moisture-absorbing box 6 is fixed to the outer surface of the protective shell 1 by a buckle. The inside is filled with highly absorbent activated carbon material, which can actively absorb moisture in the air, keep the inside of the protective shell 1 dry, prevent motor parts from rusting due to moisture, and extend the service life of the motor.

[0031] The base plate 9 is made of high-strength metal sheet. Multiple heat dissipation structures 15 are fixed on the top through a circumferential array. The edge is slidably connected to the bottom of the protective shell 1. Threaded holes 16 are opened on the surface for fixing to the external structure. A rubber sealing gasket 17 is also pasted on the top to ensure the seal with the protective shell 1.

[0032] The heat dissipation structure 15 can be a rectangular or sawtooth structure metal heat sink, which is welded and fixed to the bottom plate 9 and slides with the top of the protective shell 1 through the limiting groove 18. This not only achieves precise docking between the bottom plate 9 and the protective shell 1 through sliding, but also quickly conducts heat from the motor and improves the motor's heat dissipation efficiency.

[0033] The convenient disassembly and assembly mechanism consists of a base plate 9, a rotating plate 10, a limiting side plate 11, a clamping plate 12, a threaded rod 13, and a knob 14. Multiple mechanisms are arranged in a circular array along the edge of the base plate 9. By rotating the knob 14, the threaded rod 13 is rotated, causing the clamping plate 12 to slide under the constraint of the limiting side plate 11 (as shown in the figure, it slides back and forth with the protective shell), thus achieving engagement or disengagement with the protective shell 1, which facilitates quick disassembly and maintenance.

[0034] The lower part of the rotating plate 10 is rotatably connected to the edge of the base plate 9 via a rotating shaft. The edge of the base plate 9 is provided with corresponding protrusions. Two opposing limiting side plates 11 are welded to the surface of the rotating plate 10. The angle can be flexibly adjusted around the rotating shaft to provide installation support for the clamping plate 12. At the same time, the angle adjustment can adapt to different installation scenarios and improve the versatility of the disassembly and assembly mechanism.

[0035] The limiting side plate 11 is made of metal sheet and is welded parallel to the surface of the rotating plate 10. The opposite surfaces are provided with sliding grooves to slide with the clamping plate 12, which plays a precise constraining role on the sliding trajectory of the clamping plate 12, prevents the clamping plate 12 from deviating, and ensures the clamping stability between the clamping plate 12 and the protective shell 1.

[0036] The clamping plate 12 is made of high-strength plastic material. A threaded hole is opened in the middle to engage with the threaded rod 13. It is slidably connected to the limiting side plate 11 on both sides. The back and forth sliding guided by the limiting side plate 11 is achieved by the rotation of the threaded rod 13, thereby engaging or disengaging with the protective shell 1. It can be operated without tools, improving the convenience of disassembly and assembly.

[0037] The threaded rod 13 is made of high-strength threaded steel. One end is welded and fixed to the knob 14, and the other end passes through the rotating plate 10 and is threadedly connected to the clamping plate 12. Rotating the knob 14 can drive the threaded rod 13 to rotate, and the clamping plate 12 can be accurately displaced through the threaded transmission to ensure stable clamping force.

[0038] The knob 14 is made of non-slip plastic with a textured surface and is fixedly connected to the end of the threaded rod 13. Operators can rotate the knob 14 directly by hand to move the plate 12 without the need for tools, reducing the difficulty of disassembly and assembly and improving maintenance efficiency.

[0039] The sealing gasket 17 is made of aging-resistant rubber and is pasted on the top edge of the base plate 9. When the base plate 9 slides and connects with the protective shell 1, the sealing gasket 17 is squeezed to fill the gap, effectively preventing external moisture and dust from entering from the connection between the base plate 9 and the protective shell 1, further improving the protective effect.

[0040] The limiting groove 18 is opened on the bottom inner side of the protective shell 1. The groove size is adapted to the heat dissipation structure 15. The heat dissipation structure 15 can slide along the limiting groove 18, which not only provides guidance for the sliding cooperation between the base plate 9 and the protective shell 1, but also ensures the tight contact between the heat dissipation structure 15 and the protective shell 1, thus ensuring the heat dissipation effect.

[0041] Working principle: The ventilation openings 7 on the outer surface of the protective shell 1 allow for air circulation between the inside and outside, while the dustproof net 8 prevents dust from entering. The activated carbon moisture-absorbing box 6 absorbs moisture from the air to keep the inside dry. The base plate 9 is connected to the protective shell 1 through a convenient disassembly and assembly mechanism. During installation, the protective shell 1 is brought into contact with the base plate 9, and then the rotating plate 10 is rotated to initially engage the locking plate 12 inside the protective shell 1. The knob 14 is rotated to drive the threaded rod 13 to rotate, causing the locking plate 12, which is threaded onto the outer surface of the threaded rod 13, to slide deeper into the protective shell 1 under the restriction of the limiting side plate 11, thereby enhancing stability. This achieves the engagement or disengagement of the locking plate 12 with the protective shell 1. Multiple convenient disassembly and assembly mechanisms arranged in a circumferential array improve connection stability. The heat dissipation structure 15 on the top of the base plate 9 enhances the heat dissipation effect by sliding with the limiting groove 18 on the surface of the protective shell 1. The sealing gasket 17 ensures the sealing between the base plate 9 and the bottom of the protective shell 1. The threaded hole 16 is used to fix the base plate 9 to the external structure.

[0042] Example 1: (Reference) Figure 4 )

[0043] The heat dissipation structure 15 can be a serrated heat sink. The heat dissipation structure 15 is welded and fixed to the top of the base plate 9 and slides in conjunction with the limiting groove 18 of the protective shell 1. The purpose is that the serrated structure can increase the contact area with air. When the car is traveling at low speed and the air circulation is slow, it can accelerate the dissipation of heat from the motor. The beneficial effect is that the heat dissipation efficiency is increased by about 20% compared with the rectangular heat sink. It can prevent the motor from overheating due to insufficient heat dissipation and ensure the stable operation of the motor in low wind speed environment. At the same time, it does not affect the sliding docking between the base plate 9 and the protective shell 1 and the sealing effect of the sealing gasket 17.

[0044] Example 2: (Reference) Figure 3 )

[0045] The heat dissipation structure 15 is replaced with a rectangular heat sink. After the replacement, the heat dissipation structure 15 is still fixed to the base plate 9 and adapted to the limiting slide 18. The purpose is that the rectangular structure has a flat surface, which is not easy to accumulate dust. In the dusty automotive environment, it can reduce the problem of heat dissipation obstruction caused by dust adhesion. The beneficial effect is that there is no need to clean the heat sink frequently, reducing the maintenance frequency. Moreover, the rectangular structure is easier to process and has a lower cost, which can control the overall production cost. At the same time, it does not change the disassembly and assembly function of the convenient disassembly and assembly mechanism. The knob 14 can still easily drive the card plate 12 to realize the disassembly and assembly of the protective shell 1.

[0046] Example 3: (Reference) Figure 1-4 )

[0047] In hot and dusty areas, when using a car fan motor, the heat dissipation structure 15 can be replaced from a sawtooth structure to a rectangular structure. The rectangular heat sink is less prone to dust accumulation, which is suitable for dusty environments. The dustproof mesh 8 of the protective shell 1, together with the rectangular heat sink, can further reduce the impact of dust and ensure the heat dissipation of the motor.

[0048] In urban road conditions where temperatures are low but vehicles frequently travel at low speeds, the heat dissipation structure 15 can be replaced with a serrated structure. The increased contact area of ​​the serrated heat dissipation fins is adapted to the airflow during low-speed driving. Combined with the airflow of the vent 7, it can effectively prevent the motor from overheating. At the same time, in both replacement scenarios, the activated carbon moisture-absorbing box 6 can keep the inside dry. The convenient disassembly and assembly mechanism can also meet the maintenance needs in different scenarios.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
