The rider can move the camera mechanism to the inside of the protective frame through simple operation. This not only improves the protection of the equipment, but also effectively reduces the interference of raindrops on the camera screen in rainy days. The rotation of the rotating rod drives the connecting plate to rotate, and the rotation of the connecting plate drives the camera mechanism to rotate. The angle of the camera mechanism can be adjusted by pulling the rotating rod with one hand, which is convenient for the rider to quickly adjust the camera screen while wearing the helmet. At the same time, the card plate is used to limit the position to ensure that the angle will not deflect during riding.

[0015] (2) In the angle-adjustable smart cycling helmet camera, the baffle applies additional resistance to the stop block, and the speed of the stop block is slowed down by the resistance. The movement speed of the cylindrical rod is slowed down by the intermittent contact between the stop block and the baffle, so that the linkage plate can smoothly pull the support rod for storage. When the support rod moves, it generates friction with the corrugations, so that the influence of inertia on the support rod gradually decreases. By opening corrugations on the rubber block to increase friction, it is effectively avoided that the support rod is affected by inertia and collides after the linkage plate stops moving, thereby improving the stability of use.

[0016] (3) In the angle-adjustable smart cycling helmet camera, the rectangular plate applies an upward supporting force to the camera mechanism, making the camera mechanism more stable inside the protective frame. The round block contacts the guide plate, so that the rectangular plate automatically supports the camera mechanism that moves into the protective frame, ensuring the integrity of the camera mechanism inside the protective frame. The rectangular plate fits with the bottom of the camera mechanism during the rotation process. The rectangular plate rotates to fit the camera mechanism, ensuring that the applied support can be transmitted stably, and also preventing the rectangular plate from blocking the movement of the camera mechanism after the angle is rotated.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The inner wall of the sliding plate 5 is provided with a hole groove, the card plate 10 contacts the inner wall of the hole groove, and the side of the support rod 14 away from the sliding plate 5 contacts the inner wall of the slide groove. The angle of the camera mechanism 7 is adjusted by pulling the rotating rod 8 with one hand, which is convenient for the rider to quickly adjust the camera picture while wearing it. At the same time, the card plate 10 is used to limit the position to ensure that the angle will not deflect during riding.

[0022] A circular hole is opened on one side of the limit frame 13 close to the pull rod 11. The shape of the pull rod 11 is set to be Y-shaped. The circumferential surface of the pull rod 11 contacts the inner wall of the circular hole. Through simple operation, the rider can move the camera mechanism 7 to the inside of the protective frame 3, which not only improves the protection of the equipment, but also effectively reduces the interference of raindrops on the camera screen on rainy days.

[0023] When the present embodiment is working, the rider connects the mobile phone to the signal transmission module of the camera mechanism 7 via Bluetooth, so that the images recorded by the camera mechanism 7 are transmitted to the rider's mobile phone in real time. Then, the rider uses the elastic band 2 to fix the flexible plate 1 on the cycling helmet for use. When the angle of the camera mechanism 7 needs to be adjusted, one hand pulls the rotating rod 8 to move away from the connecting plate 6. The rotating rod 8 stretches the No. 1 spring 9 when moving. The No. 1 spring 9 is deformed by the stretching. When the rotating rod 8 moves, it drives the card plate 10 to move away from the connecting plate 6. The surface of the card plate 10 in contact with the hole groove is separated during the movement, so that the limit imposed by the sliding plate 5 on the rotating rod 8 is The position is released, and the rotating rod 8 is rotated clockwise. The rotating rod 8 drives the connecting plate 6 to rotate clockwise. The connecting plate 6 drives the camera mechanism 7 to rotate downward. After the camera mechanism 7 rotates to the predetermined position, the pulling force applied to the rotating rod 8 is gradually reduced, so that the deformed No. 1 spring 9 gradually recovers. The recovery of the No. 1 spring 9 drives the rotating rod 8 to move toward the connecting plate 6. The movement of the rotating rod 8 drives the card plate 10 to move toward the connecting plate 6. The card plate 10 contacts the new hole groove during the movement, so that the sliding plate 5 restores the limit imposed on the rotating rod 8. The angle of the camera mechanism 7 can be adjusted by pulling the rotating rod 8 with one hand, which is convenient for the rider to quickly adjust the camera picture in the wearing state. The card plate 10 is used to limit to ensure that the angle will not deflect during riding. After use, the rider pulls the pull rod 11 downward with one hand. The pull rod 11 squeezes the No. 2 spring 12 during the movement. The No. 2 spring 12 is squeezed and deformed. At the same time, the pull rod 11 moves and separates from the round hole of the limit frame 13, so that the limit imposed by the pull rod 11 on the sliding plate 5 is released. Then the other hand pushes the rotating rod 8 to move in the direction of the flexible plate 1. The movement of the rotating rod 8 drives the connecting plate 6 to move in the direction of the flexible plate 1. The movement of the connecting plate 6 drives the camera mechanism 7 to move in the direction of the flexible plate 1. At the same time, the movement of the connecting plate 6 drives the sliding plate 5 to move in the direction of the flexible plate 1. The sliding plate 5 The movement drives the support rod 14 to move toward the flexible plate 1. The support rod 14 applies a supporting force to the sliding plate 5 during the movement, so that the sliding plate 5 moves more smoothly. At the same time, the movement of the sliding plate 5 drives the limit frame 13 to move toward the flexible plate 1. After the camera mechanism 7 moves to the specified position, the pull rod 11 is released, and the deformed No. 2 spring 12 recovers and drives the pull rod 11 to move upward. The pull rod 11 passes through the circular hole during the movement, so that the movement of the sliding plate 5 is limited. Through simple operation, the rider can move the camera mechanism 7 to the inside of the protective frame 3, which not only improves the protection of the equipment, but also effectively reduces the interference of raindrops on the camera screen on rainy days.

[0024] See also Figure 1-Figure 7On the basis of the above embodiment, another embodiment of the present invention further includes a contraction device and a protective device; the contraction device includes a fixed plate 151, a cylindrical rod 152, a No. 3 spring 153, a linkage plate 154, a round block 155, a stop block 156, a blocking sheet 157, a rubber block 158 and a No. 1 spring 159, the fixed plate 151 is fixedly penetrated through the inner and outer walls of the protective frame 3, the cylindrical rod 152 slides through the inner and outer walls of the fixed plate 151, the No. 3 spring 153 is arranged between the cylindrical rod 152 and the fixed plate 151, the linkage plate 154 is fixedly installed on the side of the cylindrical rod 152 away from the No. 3 spring 153, and the round block 155 is fixedly The rubber block 158 slides through the inner wall of the linkage plate 154. The No. 1 spring piece 159 is arranged between the rubber block 158 and the linkage plate 154. The inner wall of the linkage plate 154 contacts the circumferential surface of the support rod 14. A rectangular groove is provided on one side of the fixed plate 151 close to the linkage plate 154. After the limit of the sliding plate 5 is released, the support rod 14 is pulled to move through the linkage plate 154, so that the rider can move the camera mechanism 7 without taking off the helmet.

[0025] The side of the stop block 156 away from the cylindrical rod 152 is provided with an arc surface, and the blocking piece 157 itself is elastic. The movement speed of the cylindrical rod 152 is slowed down through intermittent contact between the stop block 156 and the blocking piece 157, so that the linkage plate 154 can smoothly pull the support rod 14 for storage.

[0026] The rubber block 158 has an inclined surface 1 on one side close to the support rod 14, and has corrugations on one side away from the first spring piece 159. The corrugations on the rubber block 158 increase friction, effectively preventing the support rod 14 from colliding due to inertia after the linkage plate 154 stops moving, thereby improving stability in use.

[0027] The protective device includes a hollow box 161, a C-shaped plate 162, a second spring piece 163, a guide plate 164, a telescopic plate 165, a bending piece 166 and a rectangular plate 167. The hollow box 161 is fixedly penetrated through the bottom of the protective frame 3, the C-shaped plate 162 is slidably mounted on the inner wall of the hollow box 161, the second spring piece 163 is arranged between the C-shaped plate 162 and the hollow box 161, the guide plate 164 is fixedly mounted on a side of the C-shaped plate 162 close to the round block 155, and the telescopic plate 165 is fixedly mounted on the side of the C-shaped plate 162 close to the round block 155. It slides through the top of the C-shaped plate 162, the bending piece 166 is set between the telescopic plate 165 and the C-shaped plate 162, the rectangular plate 167 rotates and passes through the inner and outer walls of the telescopic plate 165, and the guide plate 164 is provided with a second inclined surface on the side close to the round block 155. Through the contact between the round block 155 and the guide plate 164, the rectangular plate 167 automatically supports the camera mechanism 7 moved into the protective frame 3, ensuring the integrity of the camera mechanism 7 inside the protective frame 3.

[0028] A spiral spring is arranged between the rectangular plate 167 and the telescopic plate 165. The bending piece 166 itself is elastic. The rectangular plate 167 is rotated to fit the camera mechanism 7 to ensure that the applied support can be transmitted stably and avoid the rectangular plate 167 blocking the movement of the camera mechanism 7 after the angle is rotated.

[0029] When the present embodiment is working, when the limit imposed on the sliding plate 5 is released, the pulling force exerted by the support rod 14 on the linkage plate 154 gradually decreases, so that the deformed No. 3 spring 153 recovers and drives the cylindrical rod 152 to move toward the fixed plate 151. The movement of the cylindrical rod 152 drives the linkage plate 154 to move toward the fixed plate 151. The movement of the linkage plate 154 exerts pulling force on the support rod 14. The support rod 14 moves toward the fixed plate 151 under the influence of the pulling force. The movement of the cylindrical rod 152 drives the stop block 156 to move toward the No. 3 spring 153. The arc surface 1 of the block 156 contacts the blocking piece 157 during the movement, and the block 156 continues to move to apply pressure to the blocking piece 157, and the blocking piece 157 is squeezed and deformed. The deformed blocking piece 157 exerts additional resistance on the block 156 under the action of its own elasticity, and the movement speed of the block 156 is slowed down by the influence of the resistance. When the arc surface 1 and the blocking piece 157 are separated, the deformed blocking piece 157 recovers, and the intermittent contact between the block 156 and the blocking piece 157 slows down the movement speed of the cylindrical rod 152, so that the linkage plate 154 can smoothly pull the support The support rod 14 is stored, and the linkage plate 154 moves while driving the round block 155 and the rubber block 158 to move toward the fixed plate 151. The side of the linkage plate 154 close to the fixed plate 151 contacts the rectangular groove during the movement. The linkage plate 154 is blocked by the rectangular groove and stops moving. The support rod 14 continues to move under the influence of inertia. The support rod 14 contacts the inclined surface 1 of the rubber block 158 during the movement. The support rod 14 continues to move and applies a thrust to the inclined surface 1. The rubber block 158 moves toward the first spring piece 159 under the action of the thrust. The rubber block 158 moves to squeeze the No. 1 spring sheet 159, and the No. 1 spring sheet 159 is squeezed and deformed. The deformed No. 1 spring sheet 159 exerts a reaction force on the rubber block 158, so that the corrugation of the rubber block 158 is in close contact with the circumferential surface of the support rod 14. When the support rod 14 moves, it generates friction with the corrugation, so that the influence of inertia on the support rod 14 is gradually reduced. By providing corrugations on the rubber block 158 to increase friction, it is effectively avoided that after the linkage plate 154 stops moving, the support rod 14 is affected by inertia and collides, thereby improving the stability of use; The circular block 155 contacts the second inclined surface of the guide plate 164 during the movement, and the circular block 155 moves to apply an upward thrust to the second inclined surface. The guide plate 164 moves upward under the influence of the thrust, and the guide plate 164 moves to drive the C-shaped plate 162 to move upward, and the C-shaped plate 162 moves to stretch the second spring piece 163, and the second spring piece 163 is stretched and deformed. At the same time, the C-shaped plate 162 moves to drive the telescopic plate 165 to move upward, and the telescopic plate 165 moves to drive the rectangular plate 167 to move upward. The rectangular plate 167 contacts the bottom of the camera mechanism 7 during the movement, and the rectangular plate 167 is blocked by the camera mechanism 7 and stops moving. The C-shaped plate 162 continues to move to squeeze the bent piece 166, and the bent piece 166 is squeezed and deformed. The deformed bent piece 166 applies a reaction force to the telescopic plate 165, and the telescopic plate 165 transmits the reaction force to the rectangular plate 167. The rectangular plate 167 pushes the camera mechanism 7 under the action of the reaction force. An upward supporting force is applied at the bottom, so that the camera mechanism 7 is more stable inside the protective frame 3. The round block 155 contacts the guide plate 164, so that the rectangular plate 167 automatically supports the camera mechanism 7 moved into the protective frame 3. When the angle of the camera mechanism 7 is adjusted and then moves into the protective frame 3, one side of the rectangular plate 167 contacts the bottom of the camera mechanism 7 during the upward movement, and the movement of one side of the rectangular plate 167 is blocked, so that the moving rectangular plate 167 rotates. The rotation of the rectangular plate 167 stretches the spiral spring, and the spiral spring is stretched and deformed. At the same time, the other side of the rectangular plate 167 fits with the bottom of the camera mechanism 7 during the rotation, so that the rectangular plate 167 applies a stable supporting force to the camera mechanism 7 after the angle is adjusted. The rectangular plate 167 rotates to fit the camera mechanism 7, which ensures that the applied support can be stably transmitted, and also avoids the rectangular plate 167 blocking the movement of the camera mechanism 7 after the angle is rotated.
