Description

Technical Field

[0001] The present invention relates to the technical field of motor protective casings, and particularly relates to a motor casing protective structure for a sunroof motor that is convenient for assembly. Background Art

[0002] As a core component for driving panoramic sunroofs, retractable roofs, and convertible mechanisms of automobiles, the installation position of the sunroof motor is concentrated in the roof area. Since the roof is directly exposed to high-temperature environments in summer, the internal temperature of the motor accumulates due to environmental heat radiation during the standby state, and the additional heat generated by the working load during operation will further exacerbate the temperature rise. Without an effective heat dissipation mechanism, continuous high temperatures will not only accelerate the aging of the internal insulation materials of the motor, but also reduce the operating life of the motor.

[0003] In response to the above technical problems, the applicant has retrieved some prior arts to achieve heat dissipation and temperature reduction inside the motor. For example, the patent publication number is CN119483066A, and its main technical means is to install a ball bearing fan on the motor protective casing to strengthen the air flow inside the casing, thereby taking away the heat on the surface of the motor. The ball bearing fan can change the angle to face the middle of the back of the protective casing, and at the same time, the number of ventilable places on the outside of the protective casing is increased to three, so as to accelerate the absorption of the temperature inside the protective casing. After analysis by the applicant, the disadvantages of this technical solution are as follows: in a high-temperature environment, only the high-temperature air accelerated by the fan will lead to a significant reduction in the heat exchange efficiency, making it difficult to effectively take away the heat on the surface of the motor. Moreover, the setting of multiple fans, although it can cool the motor in all directions, the heat generated by the operation of multiple fans will also cause the temperature of the environment around the motor to rise. Based on this, the present invention purposefully provides a motor casing protective structure for a sunroof motor that is convenient for assembly and can achieve high heat exchange efficiency in a high-temperature environment. Summary of the Invention

[0004] The purpose of the present invention is to provide a motor casing protective structure for a sunroof motor that is convenient for assembly in view of the deficiencies of the prior art, so as to solve the technical problems in the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A motor casing protective structure for a sunroof motor that is convenient for assembly, comprising: A protective casing, inside which a sunroof motor body is provided. An air inlet is provided on the side wall of the protective casing. A suction pipe is fixedly installed on the protective casing. A fan is fixedly installed at the air outlet of the suction pipe. A first pipe and a second pipe are communicated with the suction pipe, and both the first pipe and the second pipe are communicated with the protective casing and are symmetrically arranged. A temperature monitoring component is provided inside the protective casing; An air delivery pipe is fixedly installed on the protective housing. A first elbow pipe and a second elbow pipe are communicated with the air delivery pipe. Both the first elbow pipe and the second elbow pipe are communicated with the protective housing, and the first elbow pipe and the second elbow pipe are symmetrically arranged. The first elbow pipe and the first pipe are respectively located on both sides of the sky curtain motor body. The air inlet of the air delivery pipe is connected to the cold air supply component, and a solenoid valve is arranged at the connection between the two. Both the cold air supply component and the solenoid valve are connected to the temperature monitoring component; A heat dissipation component is arranged on the protective housing, and the heat dissipation component is connected to the temperature monitoring component. The heat dissipation component can control the second elbow pipe, the first elbow pipe, the first pipe and the second pipe to be all opened; and the heat dissipation component can control the first elbow pipe and the first pipe to be opened, and the second elbow pipe and the second pipe to be closed; the heat dissipation component can also control the first elbow pipe and the first pipe to be closed, and the second elbow pipe and the second pipe to be opened.

[0006] As a further scheme of the present invention: The heat dissipation component includes a lower rotating cylinder and an upper rotating cylinder. The lower rotating cylinder is rotatably installed in the air extraction pipe, and the lower rotating cylinder is driven by a first driving source to rotate. A first opening and a second opening are formed on the lower rotating cylinder. Two third openings are symmetrically arranged on the lower rotating cylinder. The upper rotating cylinder is rotatably installed in the air delivery pipe, and the upper rotating cylinder is driven by a second driving source to rotate. A first opening hole and a second opening hole are formed on the upper rotating cylinder. Two third opening holes are symmetrically arranged on the upper rotating cylinder. When the lower rotating cylinder rotates to make the two third openings respectively align with the first pipe and the second pipe, the upper rotating cylinder rotates to make the two third opening holes respectively align with the first elbow pipe and the second elbow pipe; when the lower rotating cylinder rotates to make the first opening align with the first pipe, the lower rotating cylinder blocks the second pipe. At the same time, the upper rotating cylinder rotates to make the first opening hole align with the first elbow pipe, and the upper rotating cylinder blocks the second opening hole; when the lower rotating cylinder rotates to make the second opening align with the second pipe, the lower rotating cylinder blocks the first opening. At the same time, the upper rotating cylinder rotates to make the second opening hole align with the second elbow pipe, and the upper rotating cylinder blocks the first opening hole.

[0007] As a further scheme of the present invention: The air delivery pipe is located at the top of the protective housing, and the air extraction pipe is located at the bottom of the protective housing.

[0008] As a further scheme of the present invention: The air inlets of the air delivery pipe and the air extraction pipe are respectively located on both sides of the protective housing, and the air inlet is arranged on the same side as the air inlet of the air delivery pipe.

[0009] As a further scheme of the present invention: A detachable filter screen is installed in the air inlet.

[0010] As a further scheme of the present invention: A sliding plate is slidably installed on the protective housing. The sliding plate is driven by an output source inside the protective housing to move. When the solenoid valve is opened, the output source drives the sliding plate to move to the air inlet and block the air inlet.

[0011] As a further solution of the present invention: A plurality of horizontally arranged plates are fixedly installed on both the bottom plate and the top plate of the protective housing at equal intervals, and an air flow channel exists between two adjacent horizontally arranged plates. The awning motor body is fixedly connected to the inside of the protective housing by abutting against the horizontally arranged plates. When the cold air flows from the first elbow to the first pipe and when the cold air flows from the second elbow to the second pipe, the cold air flows through the air flow channel.

[0012] As a further solution of the present invention: The air outlet of the air extraction pipe is communicated with a three-way stop valve. Two outlets of the three-way stop valve are respectively communicated with a first outlet and a second outlet. The first outlet is communicated with an exhaust gas pipe, and the second outlet is communicated with an internal circulation pipe.

[0013] The beneficial effects of the present invention: 1. In the present invention, the temperature monitoring component is used to monitor the temperature inside the protective housing in real time. Different heat dissipation strategies are adopted according to the temperature change. The air flow inside the protective housing is strengthened by the fan for conventional heat dissipation. If the temperature continues to rise and exceeds the threshold, the solenoid valve is opened to inject cold air into the protective housing through the air delivery pipe, and the heat dissipation efficiency is optimized by dynamically adjusting the cold air path: all channels are opened in the initial stage, and the cold air quickly flows through the inside of the protective housing to achieve overall cooling; in the middle stage, the unilateral channel is closed, so that the cold air horizontally passes over the surface of the awning motor body to extend the contact time; in the later stage, the other side channel is switched to ensure uniform heat exchange in each area of the awning motor body. This alternating air flow design not only prolongs the residence time of the cold air, but also eliminates the temperature gradient by periodically changing the flow direction; 2. In the present invention, since the density of the cold air is relatively high and it has a downward trend under the action of gravity, the air delivery pipe is arranged above the protective housing, and the cold air dissipated by the air delivery pipe itself can be used to cool the surface of the protective housing, thereby reducing the temperature around the protective housing; 3. In the present invention, considering that in a high-temperature environment, the air entering the protective housing from the air inlet is still high-temperature air. When the cold air supply component injects cold air into the protective housing through the air delivery pipe, the entry of the high-temperature air will reduce the heat dissipation and cooling effect. Therefore, when the solenoid valve is opened, that is, when the cold air supply component injects cold air into the protective housing through the air delivery pipe for cooling, the output source is used to drive the sliding plate to move to block the air inlet, preventing the high-temperature air outside the protective housing from entering and ensuring the cooling effect of the cold air on the awning motor body.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1 - 10 As shown, the present invention is a motor housing protection type structure for a sky curtain motor that is convenient for assembly, including: A protective housing 1, in which a sky curtain motor body 2 is arranged. An air inlet 101 is provided on the side wall of the protective housing 1. An exhaust pipe 3 is fixedly installed on the protective housing 1. A fan 4 is fixedly installed at the air outlet of the exhaust pipe 3. A first pipe 301 and a second pipe 302 are communicated with the exhaust pipe 3. Both the first pipe 301 and the second pipe 302 are communicated with the protective housing 1, and the first pipe 301 and the second pipe 302 are symmetrically arranged. A temperature monitoring component is arranged in the protective housing 1; The air delivery pipe 6 is fixedly installed on the protective housing 1. A first elbow pipe 601 and a second elbow pipe 602 are connected to the air delivery pipe 6. Both the first elbow pipe 601 and the second elbow pipe 602 are connected to the protective housing 1, and the first elbow pipe 601 and the second elbow pipe 602 are symmetrically arranged. The first elbow pipe 601 and the first pipe 301 are respectively located on both sides of the awning motor body 2. The air inlet of the air delivery pipe 6 is connected to the cold air supply component, and a solenoid valve 8 is provided at the connection between the two. Both the cold air supply component and the solenoid valve 8 are connected to the temperature monitoring component; The heat dissipation component is arranged on the protective housing 1 and is connected to the temperature monitoring component. The heat dissipation component can control the second elbow pipe 602, the first elbow pipe 601, the first pipe 301, and the second pipe 302 to all be opened; and the heat dissipation component can control the first elbow pipe 601 and the first pipe 301 to be opened, and the second elbow pipe 602 and the second pipe 302 to be closed; the heat dissipation component can also control the first elbow pipe 601 and the first pipe 301 to be closed, and the second elbow pipe 602 and the second pipe 302 to be opened.

[0019] In one case of this embodiment, a protective shell 14 is sleeved outside the protective housing 1. The protective shell 14 covers all components. Both the protective housing 1 and the protective shell 14 are of an assembled design. The cold air supply component can select condenser refrigeration for independent cooling, or directly connect the air inlet of the air delivery pipe 6 to the vehicle interior and choose to use the vehicle interior air conditioner for cooling; it should be noted that the temperature monitoring component and the solenoid valve 8 of the present invention are both prior arts, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention.

[0020] The working principle of the present invention: The temperature inside the protective housing 1 is monitored in real time through the temperature monitoring component. When the temperature is relatively low, the air inside the protective housing 1 naturally flows through the air inlet 101, and no heat dissipation operation is required. When the temperature rises but does not exceed the threshold, ensure that the solenoid valve 8 is closed, and through the heat dissipation component, the first pipe 301 and the second pipe 302 are opened, and the fan 4 is started. The suction generated by the fan 4 continuously extracts the high-temperature air inside the protective housing 1 through the first pipe 301 and the second pipe 302 and discharges it. The external low-temperature air fills the protective housing 1 from the air inlet 101. In this way, the rapid heat dissipation of the awning motor body 2 is achieved by accelerating the air flow inside the protective housing 1. When the temperature inside the protective housing 1 continues to rise and exceeds the threshold, the solenoid valve 8 is opened to allow the cold air of the cold air supply component to be delivered into the air delivery pipe 6. Since the temperature inside the protective housing 1 is very high at the beginning of heat dissipation, the heat dissipation component controls the second elbow pipe 602, the first elbow pipe 601, the first pipe 301, and the second pipe 302 to all be opened. At this time, such as Figure 8Taking the shown as an example, the arrows represent the cold air flow direction. The cold air is divided into two parts and enters the protective housing 1 from the first elbow 601 and the second elbow 602 respectively. After heat exchange with the high-temperature air in the protective housing 1, it carries heat and is discharged from the protective housing 1 through the first pipe 301 and the second pipe 302, and finally enters the extraction pipe 3 and is completely discharged. During this process, a large amount of cold air enters, and the first elbow 601 is discharged from the second pipe 302 nearby, and the second elbow 602 is discharged from the first pipe 301 nearby. The heat exchange rate is fast, and it can quickly take away the high-temperature air accumulated in the protective housing 1, achieving rapid cooling, thereby protecting the awning motor body 2; after a period of time, the heat dissipation component can control the first elbow 601 and the first pipe 301 to open, and the second elbow 602 and the second pipe 302 to close. At this time, as Figure 9 Taking the shown as an example, the cold air only flows into the protective housing 1 from the first elbow 601. Then the cold air moves horizontally through the protective housing 1, takes away the heat on the surface of the awning motor body 2, and is discharged from the first pipe 301. At this time, the cold air first contacts the right side area of the awning motor body 2, resulting in a better cooling effect on the right side than on the left side. After another period of time, the heat dissipation component can control the first elbow 601 and the first pipe 301 to close, and the second elbow 602 and the second pipe 302 to open. At this time, as Figure 10 Taking the shown as an example, the cold air only flows into the protective housing 1 from the second elbow 602. Then the cold air moves horizontally through the protective housing 1, takes away the heat on the surface of the awning motor body 2, and is discharged from the second pipe 302. At this time, the cold air first contacts the left side area of the awning motor body 2, and the cooling effect on the left side is obvious. Such a design can make the cold air stay in the protective housing 1 for a longer time, fully exchange heat with the remaining high-temperature air, and by changing the flow direction of the cold air, the heat dissipation effect can be made more uniform, avoiding the problem that the heat dissipation effect on one side is always better than that on the other side due to the fixed cold air flow direction, and ensuring that the entire awning motor body 2 can be in uniform contact with the cold air.

[0021] As Figures 1 - 6As shown, as a preferred embodiment of the present invention, the heat dissipation component includes a lower rotating cylinder 5 and an upper rotating cylinder 7. The lower rotating cylinder 5 is rotatably installed in the air extraction pipe 3 and is driven to rotate by a first driving source. The lower rotating cylinder 5 is provided with a first opening 501 and a second opening 502, and two symmetrically arranged third openings 503 are provided on the lower rotating cylinder 5. The upper rotating cylinder 7 is rotatably installed in the air delivery pipe 6 and is driven to rotate by a second driving source. The upper rotating cylinder 7 is provided with a first opening 701 and a second opening 702, and two symmetrically arranged third openings 703 are provided on the upper rotating cylinder 7. When the lower rotating cylinder 5 rotates until the two third openings 503 are respectively aligned with the first pipe 301 and the second pipe 302, the upper rotating cylinder 7 rotates until the two third openings 703 are respectively aligned with the first elbow 601 and the second elbow 602; when the lower rotating cylinder 5 rotates until the first opening 501 is aligned with the first pipe 301, the lower rotating cylinder 5 blocks the second pipe 302. At the same time, the upper rotating cylinder 7 rotates until the first opening 701 is aligned with the first elbow 601, and the upper rotating cylinder 7 blocks the second opening 702; when the lower rotating cylinder 5 rotates until the second opening 502 is aligned with the second pipe 302, the lower rotating cylinder 5 blocks the first opening 501. At the same time, the upper rotating cylinder 7 rotates until the second opening 702 is aligned with the second elbow 602, and the upper rotating cylinder 7 blocks the first opening 701.

[0022] In one case of this embodiment, the first driving source and the second driving source can both be selected from components such as servo motors and servo motors, and other mechanisms capable of realizing rotational motion can also be selected. This embodiment does not specifically limit this here.

[0023] In the actual application of this embodiment, the cooperation between the lower rotating cylinder 5 and the air extraction pipe 3 actually has the same effect as the cooperation between the upper rotating cylinder 7 and the air delivery pipe 6. Therefore, only one of them needs to be explained. Since the first pipe 301 and the second pipe 302 are symmetrically arranged, the interfaces between them and the air extraction pipe 3 are also symmetrically arranged. The two third openings 503 on the lower rotating cylinder 5 are symmetrically arranged. Therefore, when the lower rotating cylinder 5 rotates until the third opening 503 is aligned with the first pipe 301, the other third opening 503 will naturally be aligned with the second pipe 302, as Figure 5Taking the example shown, the axes of the second opening 502 and the first opening 501 can be specifically given positions where they are plus or minus sixty degrees with respect to the axis of the third opening 503 indicated by the mark. In this way, when the lower rotating cylinder 5 rotates clockwise by sixty degrees, the first opening 501 aligns with the first pipeline 301, and the lower rotating cylinder 5 will block the second pipeline 302. When the lower rotating cylinder 5 continues to rotate clockwise by sixty degrees, the lower rotating cylinder 5 will block the first pipeline 301, and the second opening 502 will align with the second pipeline 302. Thus, different states can be switched only by rotating the lower rotating cylinder 5 by sixty degrees each time. Compared with using multiple valves to control the opening and closing of the first pipeline 301 and the second pipeline 302, this method can not only achieve the same control effect but also save costs.

[0024] As Figures 1 - 4 shown, as a preferred embodiment of the present invention, the gas transmission pipe 6 is located at the top of the protective housing 1, and the air extraction pipe 3 is located at the bottom of the protective housing 1.

[0025] In actual application of this embodiment, since the density of the cold air is relatively high and it has a downward trend under the action of gravity, setting the gas transmission pipe 6 above the protective housing 1 can cool the surface of the protective housing 1 through the cold air emitted by the gas transmission pipe 6 itself, thereby reducing the temperature around the protective housing 1.

[0026] As Figures 1 - 4 shown, as a preferred embodiment of the present invention, the air inlet of the gas transmission pipe 6 and the air outlet of the air extraction pipe 3 are respectively located on both sides of the protective housing 1, and the air inlet 101 is arranged on the same side as the air inlet of the gas transmission pipe 6.

[0027] In actual application of this embodiment, since the air extraction pipe 3 discharges the cold air that has passed through the protective housing 1, the cold air will heat up after heat exchange with the high-temperature air. By setting the air inlet of the gas transmission pipe 6 and the air outlet of the air extraction pipe 3 on both sides of the protective housing 1, and arranging the air inlet 101 on the same side as the air inlet of the gas transmission pipe 6, on the one hand, it can prevent the high-temperature air discharged by the air extraction pipe 3 from being re-sucked into the protective housing 1, and the high-temperature air discharged by the air extraction pipe 3 will not come into contact with the surface of the gas transmission pipe 6, thus avoiding the problem that the temperature of the cold air flowing in the gas transmission pipe 6 rises. On the other hand, it can make the air flow into the protective housing 1 from one side and flow out from the other side, ensuring contact with the entire surface of the protective housing 1 for sufficient cooling.

[0028] As Figures 1 - 2 shown, as a preferred embodiment of the present invention, a detachable filter screen 9 is installed in the air inlet 101.

[0029] In actual application of this embodiment, the filter 9 can intercept impurities in the air to prevent the impurities from entering the protective shell 1, and further prevent the impurities from entering the canopy motor body 2. The detachable design of the filter 9 can facilitate the cleaning and replacement of the filter 9 to ensure the filtering effect.

[0030] like Figures 1 - 10 As shown, as a preferred embodiment of the present invention, a slide plate 10 is slidably installed on the protective shell 1, and the slide plate 10 is driven to move by an output source built into the protective shell 1. When the solenoid valve 8 is opened, the output source drives the slide plate 10 to move to the air inlet 101 to block the air inlet 101.

[0031] In one case of this embodiment, the output source may be an electric cylinder, an electric telescopic rod, or other components, or other mechanisms capable of achieving linear reciprocating motion, which is not specifically limited in this embodiment.

[0032] In actual application of this embodiment, considering that in a high temperature environment, the air entering the protective shell 1 from the air inlet 101 is still high temperature air, when the cooling air supply component inputs the cold air into the protective shell 1 through the air pipe 6, the entry of high temperature air will reduce the heat dissipation and cooling effect. Therefore, when the solenoid valve 8 is opened, that is, the cooling air supply component inputs the cold air into the protective shell 1 through the air pipe 6 for cooling, the output source drives the slide plate 10 to move and block the air inlet 101 to prevent the high temperature air outside the protective shell 1 from entering, thereby ensuring the cooling effect of the cold air on the skylight motor body 2.

[0033] like Figures 1 - 7 As shown, as a preferred embodiment of the present invention, the bottom plate and the top plate of the protective shell 1 are fixedly installed with multiple horizontal plates 12 arranged at equal intervals, and there is an air flow channel 13 between two adjacent horizontal plates 12, and the skylight motor body 2 is fixed in the protective shell 1 by abutting the horizontal plates 12. When the cold air flows from the first bend 601 to the first pipe 301 and the cold air flows from the second bend 602 to the second pipe 302, the cold air flows through the air flow channel 13.

[0034] In actual application of this embodiment, the canopy motor body 2 can be clamped and fixed in the middle by the provision of the horizontal plate 12, especially the horizontal plate 12 fixed on the bottom plate of the protective shell 1, which avoids the entire bottom surface of the canopy motor body 2 from contacting the bottom plate of the protective shell 1. The contact points of the bottom surface of the protective shell 1 are reduced by the spaced horizontal plates 12, and when the cold air flows through the air flow channel 13, it can also quickly take away the heat on the surface of the canopy motor body 2.

[0035] like Figures 1 - 10As shown, as a preferred embodiment of the present invention, the air outlet of the air extraction pipe 3 is connected to a three-way stop valve 11. The two outlets of the three-way stop valve 11 are respectively connected to a first outlet 1101 and a second outlet 1102. The first outlet 1101 is connected to an exhaust gas pipe, and the second outlet 1102 is connected to an internal circulation pipe.

[0036] In a case of this embodiment, it should be noted that the three-way stop valve 11 described in the present invention is a prior art, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0037] When this embodiment is actually applied, when heat exchange is carried out inside the cold air delivery protection housing 1, at the beginning, the air discharged from the air extraction pipe 3 has a relatively high temperature. At this time, the first outlet 1101 is opened and the second outlet 1102 is closed, so as to directly discharge the high-temperature air. After a period of time, the temperature inside the protection housing 1 is relatively low as a whole. At this time, the first outlet 1101 is closed and the second outlet 1102 is opened, and the low-temperature air is discharged into the internal circulation pipe, which can be used for the preliminary cooling of other heating components, so as to recycle the cold air resources.

[0038] The above has described a detailed description of an embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and cannot be considered as being used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
