Description

Technical Field

[0001] This utility model relates to the field of electric motor installation technology, specifically to an installation support structure for an electric marine motor. Background Technology

[0002] An electric boat is a vessel powered by electricity. It is mainly propelled by electricity generated by batteries or marine generators. The electric motor is the core component of an electric boat. It converts electrical energy into mechanical energy, which drives the propeller or water jet propulsion to propel the boat forward. The speed of the boat can be controlled by adjusting the speed of the electric motor.

[0003] A Chinese patent provides a drive structure for an outboard motor of an electric boat, publication number CN113443111A, which includes a first support plate, a first motor, a second motor, a transmission shaft, a first helical gear, a rotating shaft, a third helical gear, a first blade, a fourth helical gear, a connecting body, and a second blade.

[0004] The above-mentioned device drives the first motor shaft and the second motor shaft to rotate in the same direction and at the same speed through the first motor and the second motor shaft rotating in the same direction and at the same speed. The gears of the first motor shaft and the second motor shaft drive the transmission shaft gear to rotate. The transmission shaft gear drives the first helical gear to rotate. The first helical gear drives the third helical gear and the fourth helical gear to rotate in opposite directions, thereby causing the first blade and the second blade to rotate in opposite directions, providing driving force for the ship to move forward.

[0005] However, its support structure is relatively simple, and the motor is installed by fixing it. It is difficult to adjust the fixed position as needed, and it is also difficult to adjust the locking force. When the motor is running, it may generate a lot of vibration and noise. Utility Model Content

A support plate is movably mounted on the top of the fixing plate via a movable rod, and an mounting plate is mounted on the inner side of the support plate via adjusting bolts.

[0009] A motor noise reduction mounting box is installed at the center of the top of the mounting plate, and the motor body is installed inside the motor noise reduction mounting box. A spring is arranged around the outer ring of the movable rod. The upper and lower ends of the spring abut against the opposite surfaces of the fixed plate and the support plate, respectively. Circular dampers are arranged on both sides of the top of the fixed plate. An adjusting hydraulic cylinder is installed on one side of the fixed plate. The drive push rod of the adjusting hydraulic cylinder is connected to the outer side of the support plate through connecting bolts.

[0010] Preferably, the fixed plate has an internal groove that adapts to the movable rod, and a buffer rubber pad is provided at the lower part of the internal groove.

[0011] Preferably, the inner side of the support plate is provided with an adjustment hole that is compatible with the adjustment thread hole, and the outer side of the mounting plate is in contact with the inner side of the support plate.

[0014] Preferably, a shock-absorbing pad is provided at the connection between the fixing plate and the support base, and the fixing plate is detachably connected to the support base by fixing bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model uses an adjustable hydraulic cylinder, a fixed plate, a support plate, and a mounting plate that work together. After the motor is installed, the support stiffness at the spring can be adjusted by adjusting the extension and retraction of the hydraulic cylinder's push rod, so as to adjust the vibration isolation effect according to the motor's condition, making it highly flexible in use.

[0017] By using a mounting plate, adjustment holes, support plate, and motor noise reduction mounting box, the installation height of the motor noise reduction mounting box can be adjusted as needed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 An electric motor mounting support structure for a marine electric motor includes a support base 1. Fixing plates 2 are mounted on both sides of the top of the support base 1 by fixing bolts. A support plate 4 is movably mounted on the top of the fixing plate 2 by a movable rod 3. An mounting plate 5 is mounted on the inner side of the support plate 4 by adjusting bolts.

[0025] See Figure 2 Furthermore, a motor noise reduction mounting box 6 is installed at the center of the top of the mounting plate 5, and the motor body is installed inside the motor noise reduction mounting box 6. A spring 9 is arranged around the outer ring of the movable rod 3. The upper and lower ends of the spring 9 abut against the opposite surfaces of the fixed plate 2 and the support plate 4, respectively. A circular damper 10 is arranged on both sides of the top of the fixed plate 2. An adjusting hydraulic cylinder 13 is installed on one side of the fixed plate 2. The drive push rod of the adjusting hydraulic cylinder 13 is connected to the outer side of the support plate 4 through connecting bolts. An movable groove that adapts to the movable rod 3 is arranged inside the fixed plate 2. A buffer rubber pad 8 is arranged at the lower part of the movable groove. An opening is arranged at the bottom of the motor noise reduction mounting box 6. A protective sleeve 7 is arranged at the bottom of the motor noise reduction mounting box 6 and around the opening.

[0026] Specifically, the noise reduction mounting box 6 installed on the motor can reduce the noise generated by the electric starter. When the motor is running, the support stiffness of the motor can be adjusted by extending or retracting the push rod of the hydraulic cylinder 13. According to the operating status of the motor and the movement of the hull, the push rod of the hydraulic cylinder 13 can be controlled to retract or extend to compress or stretch the spring 9, thereby adjusting its stiffness. The circular damper 10 installed can reduce vibration of the support plate 4. By adjusting back and forth, the motor can move freely to a certain extent, reducing the impact on the hull, so as to achieve the best vibration isolation effect and further suppress noise.

[0027] Example 2

[0028] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, the inner side of the support plate 4 is provided with an adjustment hole 11 that is compatible with the adjustment thread hole. The outer side of the mounting plate 5 is attached to the inner side of the support plate 4. The mounting plate 5 is detachably connected to the support plate 4 through the adjustment hole 11 and the adjustment bolt. The support plate 4 is detachably connected to the drive push rod of the adjusting hydraulic cylinder 13 through the connecting bolt. A shock-absorbing pad 12 is provided at the connection between the fixing plate 2 and the support base 1. The fixing plate 2 is detachably connected to the support base 1 through the fixing bolt.

[0029] Specifically, because the support plate 4 is provided with several adjustment holes 11, when the motor noise reduction mounting box 6 is installed, the mounting plate 5 can be installed at a suitable support height using mounting bolts as needed to adjust the installation height of the motor noise reduction mounting box 6. Furthermore, the fixed plate 2, movable rod 3, support plate 4, and mounting plate 5 are all set separately so that they can be replaced individually after damage, which provides high flexibility and facilitates subsequent maintenance and replacement.

[0030] In actual operation, the noise generated by the electric motor starting can be reduced by the motor noise reduction mounting box 6. When the motor is running, the support stiffness of the motor can be adjusted by adjusting the extension and retraction of the push rod of the hydraulic cylinder 13. According to the operating status of the motor and the movement of the hull, the push rod of the hydraulic cylinder 13 can be controlled to retract or extend to compress or stretch the spring 9, thereby adjusting its stiffness. The circular damper 10 can reduce the vibration of the support plate 4. By adjusting back and forth, the motor can move freely to a certain extent, reducing the impact on the hull, so as to achieve the best vibration isolation effect and further suppress noise.

[0031] Because the support plate 4 is provided with several adjustment holes 11, when installing the motor noise reduction mounting box 6, the mounting plate 5 can be installed at a suitable support height using mounting bolts as needed to adjust the installation height of the motor noise reduction mounting box 6. In addition, the fixed plate 2, movable rod 3, support plate 4, and mounting plate 5 are all set separately so that they can be replaced individually after damage, which provides high flexibility and facilitates subsequent maintenance and replacement.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
