Specifically, the embodiment of the present invention does not specifically limit the material of the first guide piece 154, the second guide piece 164, the first blocking piece 156, and the second blocking piece 166, as long as the effect of the flexible butt can be achieved. For example, the first guide piece 154, the second guide piece 164, the first blocking piece 156, and the second blocking piece 166 may be made of rubber or resin. In addition, the contact surfaces of the first guide piece 154 and the first blocking piece 156 and the contact surfaces of the second guide piece 164 and the second blocking piece 166 may be provided with anti-slip patterns to increase the friction force of the contact surfaces. The friction force is used to drive the first bevel gear 170 and the second bevel gear 180.
As shown in fig. 4, the gear box 120 includes a first housing 122 and a second housing 124 that are fastened to each other, a first through hole 126 and a second through hole (not shown in fig. 4) are disposed on opposite surfaces of the first housing 122 and the second housing 124, a first connecting shaft 152 is disposed in the first through hole 126, a second connecting shaft 162 is disposed in the second through hole, referring to fig. 4 again, a first elastic member 158 is sleeved on the first connecting shaft 152 between the first blocking piece 156 and an outer wall of the gear box 120, and a second elastic member 168 is sleeved on the second connecting shaft 162 between the second blocking piece 166 and the outer wall of the gear box 120.
Specifically, the first elastic member 158 and the second elastic member 168 can both adopt compression springs, and both ends of the compression springs respectively abut against the first blocking piece 156 and the outer wall of the gear box 120 and the second blocking piece 166 and the outer wall of the gear box 120. The elastic force of the compression spring provides the first blocking piece 156 with an elastic force against the first guide piece 154, and provides the second blocking piece 166 with an elastic force against the second guide piece 164. The radial friction force is increased through the positive abutting force, the maximum value of the friction resistance is in direct proportion to the pre-tightening elastic force of the spring, and the pre-tightening elastic force of the spring can be adjusted through the distance between the first blocking piece 156 and the gear box 120 and the distance between the second blocking piece 166 and the gear box 120 respectively, so that the required friction force is met and the force required for transmitting the torque is provided.
Optionally, as shown in fig. 5, a first elastic pad 159 is disposed on the first guide piece 154 or the first blocking piece 156, and the first guide piece 154 and the first blocking piece 156 are abutted by the first elastic pad 159; the second guide piece 164 or the second stopper 166 is provided with a second elastic pad 169, and the second guide piece 164 and the second stopper 166 are abutted by the second elastic pad 169.
Specifically, the first elastic pad 159 and the second elastic pad 169 may be made of a material having elasticity, such as rubber, resin, or the like. The first and second elastic pads 159 and 169 are slightly compressed when being stressed, so that better elastic supporting and resisting force is provided between the first guide piece 154 and the first blocking piece 156 and between the second guide piece 164 and the second blocking piece 166, which is convenient for increasing the transmission stability of the first damping connector 150 and the second damping connector 160.
The first and second elastic pads 159 and 169 have non-slip patterns on their surfaces. In this way, the contact surface has a larger friction force, which is beneficial to providing a larger torque for the first bevel gear 170 and the second bevel gear 180, thereby improving the stability of the transmission.
Optionally, the first damping connector 150 and the second damping connector 160 are sleeved with connection sleeves, and the connection sleeves are located between the outer wall of the gear case 120 and the holder 110. Therefore, the deflection generated when the first damping connector 150 and the second damping connector 160 transmit torque can be reduced, which is beneficial to enabling the camera 105 to turn or rotate more stably, and the probability of the stress deflection of the first damping connector 150, the second damping connector 160 or the gear box 120 in the transmission process is reduced.
The reference circle diameter of the first bevel gear 170 is equal to the reference circle diameter of the second bevel gear 180, and the reference circle diameter of the first bevel gear 170 is smaller than or equal to the reference circle diameter of the third bevel gear 190. When the reference circle diameter of the first bevel gear 170 is smaller than the reference circle diameter of the third bevel gear 190, a higher transmission ratio and a higher torque can be obtained, which are beneficial to improving the accuracy of the camera 105 during overturning or rotating, for example, when the camera 105 is overturned by 180 degrees or rotated by 360 degrees, the position accuracy is promoted, and the position deviation during the movement process is reduced. In addition, since the first bevel gear 170, the second bevel gear 180, and the third bevel gear 190 are small, in order to ensure compact assembly and miniaturization of the overall structure, the pitch circle diameter of the first bevel gear 170 may also be equal to the pitch circle diameter of the third bevel gear 190, and the first driver 130 and the second driver 140 themselves are relied upon for the purpose of speed reduction.
Alternatively, the tooth shapes of the first bevel gear 170, the second bevel gear 180, and the third bevel gear 190 are straight teeth or helical teeth. Therefore, stable meshing between the gears can be guaranteed, and stability of the transmission process is improved.
As shown in fig. 3, the first driver 130 includes a first motor 132 and a first decelerator 134 connected to the first motor 132; the second driver 140 includes a second motor 142 and a second decelerator 144 connected to the second motor 142.
Specifically, the first motor 132 and the second motor 142 are both micro motors to reduce the occupied space, and the micro motors are preferably direct current stepping motors. In addition, the first speed reducer 134 and the second speed reducer 144 may adopt gear speed reducers, which is beneficial to reducing noise in the transmission process, improving user experience, and increasing transmission ratio and transmission torque, so that transmission is more stable and reliable.
