Description

Technical Field

[0001] The utility model relates to the technical field of ventilation fans, in particular to a motor mounting seat of a ventilation fan for a cabin. Background Art

[0002] The shelter has high mobility. According to different needs, the corresponding structure is designed inside, and relevant equipment is installed to have specific functions. It is widely used in mobile command systems, communications, medical treatment, and logistics support.

[0003] The ventilation fans on the shelters play a role in ventilation. The ventilation fans are often equipped with shutter structures, which can be opened and closed automatically to achieve dust and water-proof effects. The ventilation fans are the best choice for cooling and ventilation in modern shelters. The ventilation fans with environmental protection and energy-saving characteristics will become ventilation and cooling equipment and the mainstream of the market.

[0004] In the prior art, there are related patent applications that disclose ventilation fan structures for shelters. For example, the patent with announcement number CN217269860U discloses an outdoor shelter roof-mounted ventilation fan with shielding function, which drives the first right connecting plate to adjust up and down through the rotation of the plug rod, drives the connecting piece to adjust up and down through the first right connecting plate, and drives the window leaf to change its angle through the connecting piece. Another example is the patent with announcement number CN212899067U, which discloses a manual and automatic ventilation fan structure for shelters. The motor drives the active gear rod to rotate forward and drives the driven gear rod to rotate counterclockwise and drive the swing rod. The swing rod drives the connecting rod to push the blade synchronization rod to move linearly. The blade synchronization rod drives the blade connecting piece and causes the blade to rotate.

[0005] Screw drive is a commonly used transmission structure in the mechanical field. Screw drive has the following advantages: the transmission accuracy of the screw is relatively high, which can ensure the measurement accuracy of the device; the structure of the screw drive system is relatively simple, which reduces the failure points and improves its reliability; the structure of the screw is relatively simple, which can greatly reduce the manufacturing cost. In the above-mentioned prior art, the shutters are opened by a bevel gear transmission structure, and no screw drive is used.

[0006] Screw drive is often used in conjunction with screw nuts and motors. In the ventilation fan for cabins, if screw drive is used to control the opening and closing of the shutters, how to install the screw, screw nut and motor is an urgent problem to be solved. Utility Model Content

[0031] Combination Figures 1 to 4 As shown, a motor mounting base of a ventilation fan for a square cabin includes a base body 1, which has a U-shaped groove with an open top, and a partition 2 is arranged in the middle of the U-shaped groove; the partition 2 divides the U-shaped groove of the base body 1 into a first compartment 3 and a second compartment 4; the first compartment 3 is used to accommodate a lead screw 5 and a lead screw nut 6 screwed on the lead screw 5; the second compartment 4 is used to accommodate a motor 7; a U-shaped opening 2a with an open top is arranged in the top center of the partition 2 for passing the output shaft of the motor 7, and a screw through hole 2b is arranged in the partition 2 for passing screws to fix the motor 7.

[0032] Combination Figure 5As shown, when the above motor mounting seat is in use, the two motor mounting seats are mounted on the boss of the fan bracket 10, the motor 7 is mounted in the second compartment 4, and is connected to the front end surface of the motor 7 by using a screw through the screw hole 2b on the partition 2, thereby fixing the motor 7 on the partition 2. At the same time, the lead screw 5 and the lead screw nut 6 screwed on the lead screw 5 are installed in the first compartment 3, and the output shaft of the motor 7 passes through the U-shaped opening 2a on the partition 2 and extends into the first compartment 3 to connect with the lead screw 5. The lead screw nut 6 is connected to the connecting rod assembly on the blind. The fan bracket 10, the blinds mounted on the fan bracket 10, and the connecting rod assembly on the blinds are all prior art, and will not be described here. The lead screw 5 is driven to rotate by the motor 7 installed in the second compartment 4, thereby driving the lead screw nut 6 to move along the axis of the lead screw 5, and then the blinds are driven to open or close through the connecting rod assembly on the blinds. Therefore, the motor mounting seat provides installation space for the lead screw 5, the lead screw nut 6 and the motor 7, so that the ventilation fan for the square cabin adopts the lead screw drive to control the opening and closing of the shutter.

[0033] Combination Figures 1 to 3 As shown, a support block 8 is provided on the bottom plate of the first chamber 3 at one end away from the partition 2, and a bearing mounting hole 8a is provided on the support block 8. The bearing mounting hole 8a is a countersunk hole, and the open end of the bearing mounting hole 8a faces the partition 2. Figure 5 As shown, when in use, the bearing mounting hole 8a is used to install the bearing, and the end of the screw 5 away from the motor 7 can be inserted into the inner ring of the bearing, which supports the screw 5 and prevents the screw 5 from forming a cantilever structure, which is beneficial to ensure that the axis of the screw 5 coincides with the axis of the motor 7, thereby ensuring the stability of the transmission.

[0034] Combination Figure 2 , Figure 3 As shown, an oil injection hole 8b is provided on the outer surface of the support block 8 away from the partition plate 2, and the oil injection hole 8b is connected to the bearing mounting hole 8a; the oil injection hole 8b is coaxially arranged with the bearing mounting hole 8a. The oil injection hole 8b is used to inject lubricating butter to lubricate the bearing in the bearing mounting hole 8a.

[0035] Combination Figure 1 , Figure 3 As shown, a connecting plate 9 is formed on the bottom plate of the first compartment 3 away from the end surface of the partition 2, and a first bolt through hole 9a is provided on the connecting plate 9; a second bolt through hole 4a is provided on the bottom plate of the second compartment 4. When the motor mounting base is mounted on the boss of the fan bracket 10, two bolts are respectively passed through the first bolt through hole 9a and the second bolt through hole 4a to fix the entire motor mounting base on the boss of the fan bracket 10. The schematic diagram after installation is shown in FIG. Figure 5As shown, specifically, the bolts pass through the first bolt through hole 9 a and the second bolt through hole 4 a from the back side of the boss of the fan bracket 10 and are connected to the hexagonal nut column 11 , thereby fixing the entire motor mounting base on the boss of the fan bracket 10 .

[0036] Combination Figure 1 , Figure 4 As shown, the top surface of the bottom plate of the first chamber 3 is a plane, and the roughness is not greater than Ra0.8; the top surface of the bottom plate of the first chamber 3 is used for sliding cooperation with the bottom surface of the lead screw nut 6. In actual use, the lead screw nut 6 is a hexagonal structure. During the movement of the lead screw nut 6 along the axis of the lead screw 5, the bottom surface of the lead screw nut 6 forms a sliding cooperation with the top surface of the bottom plate of the first chamber 3. Therefore, in order to ensure the smoothness of sliding, the roughness of the top surface of the bottom plate of the first chamber 3 is required to be not greater than Ra0.8.

[0037] Combination Figure 1 , Figure 3 and Figure 4 As shown, a T-slot 3a is provided on the bottom plate of the first compartment 3 for slidingly installing a T-bolt; the T-slot 3a is parallel to the long direction of the seat body 1. When in use, the T-bolt passes through the T-slot 3a and is threadedly connected with the screw nut 6, and the T-head of the T-bolt slides with the T-slot 3a. Therefore, the purpose of providing the T-slot 3a is to install the T-bolt, thereby ensuring the stability of the movement of the screw nut 6. Furthermore, the number of the T-slots 3a is two, and the two T-slots 3a are arranged parallel to each other and spaced apart. The purpose of providing two T-slots 3a is to further ensure the stability of the movement of the screw nut 6.

[0038] Combination Figure 1 , Figure 3 As shown, a first through hole 3b is provided at the end of one T-slot 3a close to the partition 2; a second through hole 3c is provided at the end of the other T-slot 3a away from the partition 2; the first through hole 3b and the second through hole 3c both penetrate the bottom plate of the first compartment 3. The purpose of providing the first through hole 3b and the second through hole 3c is to facilitate the installation of the T-bolt, that is, during assembly, the T-bolt is inserted from the first through hole 3b and the second through hole 3c and is threadedly connected with the lead screw nut 6, and the T-nut slides into the T-slot 3a from the first through hole 3b and the second through hole 3c. The reason why the first through hole 3b and the second through hole 3c are provided at the two ends is to prevent the two T-bolts from falling off from the T-slot 3a at the same time.

[0039] Combination Figure 1 As shown, the height of the two side panels of the first compartment 3 is lower than the height of the two side panels of the second compartment 4. Figure 5As shown, when in use, the screw nut 6 is connected to the connecting rod assembly on the shutter. In order to avoid interference of the two side plates of the first cabin 3 with the connecting rod, the height of the two side plates of the first cabin 3 is set lower than the height of the two side plates of the second cabin 4.

[0040] Combination Figure 4 As shown, the number of the screw holes 2b is at least two, and they are symmetrically distributed on both sides of the U-shaped opening 2a. The function of the screw holes 2b is to fix the motor 7, that is, the screw passes through the screw holes 2b and is connected and fixed to the front end surface of the motor 7. The purpose of the screw holes 2b being symmetrically disposed on both sides of the U-shaped opening 2a is to ensure that the screw pre-tightening force applied to the motor 7 when it is fixed is evenly distributed.
