[0033] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —7:

[0034] A reverse gear anti-tilting structure for a low-horsepower electric outboard motor includes two clamping brackets 1 and a rotating bracket 2 disposed between the two clamping brackets 1. An angle limiting pin 3 is provided at the lower part of the clamping bracket 1. The upper front end of the rotating bracket 2 is hinged to the clamping bracket 1 via a hinge shaft 4. When the lower part of the rotating bracket 2 abuts against the angle limiting pin 3, it restricts the forward rotation of the rotating bracket 2 around the hinge shaft 4. A reverse lock bracket 5 is vertically slidable along the upper edge of the rotating bracket 2. The lower end of the reverse lock bracket 5 is provided with an abutment block 51. When the reverse lock bracket 5 is moved down and the abutment block 51 is located in front of the angle limiting pin 3, the abutment block 51 abuts against the angle limiting pin 3 to restrict the rotating bracket 2 from rotating backward around the hinge axis 4, and the rotating bracket 2 is in a locked state. When the reverse lock bracket 5 is moved up and the abutment block 51 does not abut against the angle limiting pin 3, the rotating bracket 2 can rotate backward around the hinge axis 4, and the rotating bracket 2 is in an unlocked state.

[0035] The working principle of this utility model is as follows: Figure 1 , 2 As shown, when the angle of the rotating bracket 2 needs to be adjusted, the reverse lock bracket 5 is moved upward, and the rotating bracket 2 is in the unlocked state. The angle limiting pin 3 is pulled out, allowing the rotating bracket 2 to rotate around the hinge axis 4. After the position of the rotating bracket 2 is adjusted, the angle limiting pin 3 is inserted into the clamping bracket 1. When the lower part of the rotating bracket 2 abuts against the angle limiting pin 3, the rotating bracket 2 is restricted from rotating forward around the hinge axis 4. In reverse gear, the reverse lock bracket 5 is moved downward, and the abutment block 51 is located in front of the angle limiting pin 3. The abutment block 51 abuts against the angle limiting pin 3, restricting the rotating bracket 2 from rotating backward around the hinge axis 4. The rotating bracket 2 is in the locked state, effectively preventing the electric outboard motor from tilting up when running in reverse gear. When tilting is required, the reverse lock bracket 5 is moved upward, and the abutment block 51 no longer abuts against the angle limiting pin 3. The rotating bracket 2 can rotate backward around the hinge axis 4, and the rotating bracket 2 is in the unlocked state.

[0036] This utility model features a reverse lock bracket 5 vertically sliding on a rotating bracket 2, with an abutment block 51 at the lower end of the reverse lock bracket 5. The rotating bracket 2 is unlocked and locked only by the abutment block 51. The structure is simple, with few parts, and is easy to process and install.

[0040] In order to better provide resistance to the up and down movement of the lock body 52, the first block 62 has a protrusion 64 protruding from the groove side to abut against the lock body 52.

[0041] In order to further provide resistance to the up and down movement of the lock body 52, the protrusion 64 is provided with a pressing block 66 that presses against the lock body 52. ​​The pressing block 66 is elongated and its length is arranged vertically.

[0042] Preferably, two pressure blocks 66 are arranged in parallel.

[0045] To facilitate the switching of the positioning block 65 between the upper positioning groove 54 and the lower positioning groove 55, both the first blocking block 62 and the second blocking block 63 are made of elastic material.

[0046] Furthermore, the elastic material is nylon or rubber. In this embodiment, both the first block 62 and the second block 63 are made of nylon.

[0047] The mounting structure of the damping block 6 includes a waist-shaped hole 56 on the lock body 52. ​​The length of the waist-shaped hole 56 is vertically oriented. The shank of the screw 7 passes through the first damping block 62, the waist-shaped hole 56, and the second damping block 63, and is screwed to the rotating bracket 2. The structure is simple and easy to install.

[0048] Structure of the lock body 52: The lock body 52 includes two limiting plates 521 arranged in parallel on the left and right sides and a connecting plate 522 connecting the two limiting plates 521.

The lower ends of the two limiting plates 521 are respectively provided with the abutment block 51, which better abuts against the angle limiting pin 3, resulting in a good locking effect.

[0049] Furthermore, the lower end of the reverse lock bracket 5 is provided with a limiting block 57 located behind the abutment block 51, and a slot 58 for engaging the angle limiting pin 3 is formed between the limiting block 57 and the abutment block 51.
