[0053] Reference is made to Figures 1-5 .

[0054] The present embodiment provides an intelligent bird feeder, which mainly comprises a main frame 1, a bin cover 2, a movable step 3, and a linkage mechanism 4.

[0055] A bin body 11 for storing bird food is arranged in the main frame 1, and a feeding opening 12 communicating with the bin body 11 is arranged at the lower part of the main frame 1. The bird food stored in the bin body 11 flows to the feeding opening 12 under the action of gravity, so that birds can eat from the top opening of the feeding opening 12.

[0056] The main body of the bin cover 2 is arranged at the top opening of the feeding port 12 to serve as a door to close the opening of the feeding port 12. The left and right sides of the bin cover 2 are respectively hingedly connected to the left and right side plates of the feeding port 12, and the bin cover 2 can be flipped along the straight line formed by the hinged connection portions on the two sides to open and close the opening of the feeding port 12.

[0057] The movable tread part 3 includes a front tread part 31 and two rear connecting rods 32. The front tread part 31 is located at the front end of the feeding port 12 to allow the birds to stand thereon to eat the bird food. The two rear connecting rods 32 extend from the rear end of the front tread part 31 and can be straight or bent. The two rear connecting rods 32 can be fixed to the left and right sides of the rear end of the front tread part 31 by connection or can be an integral structure with the front tread part 31. The rear ends of the two rear connecting rods 32 are respectively hingedly connected to the outer sides of the left and right side plates of the feeding port 12, and the two rear connecting rods 32 can be synchronously rotated along the rotation axes formed by the hinged connection portions. That is, when the front tread part 31 moves downward, the two rear connecting rods 32 are synchronously flipped downward around the rotation axes.

[0058] The linkage mechanism 4 is arranged on the outer side of the left or right side plate of the feeding port 12, that is, only one linkage mechanism 4 can be arranged on one side plate, or two linkage mechanisms 4 can be arranged on the left and right side plates of the feeding port 12. For convenience of description, the side plate provided with the linkage mechanism 4 is referred to as the first side plate.

[0059] The linkage mechanism 4 is hingedly connected between the rear connecting rod 32 and the hinged connection portion of the bin cover 2 on the first side plate, that is, one end of the linkage mechanism 4 is hingedly connected to any rear connecting rod 32, and the other end is hingedly connected to the hinged connection portion of the bin cover 2 on the first side plate, so that when the front tread part 31 is flipped, the bin cover 2 is flipped by the linkage mechanism 4 to realize automatic closing or opening of the bin cover 2. In this embodiment, when the front tread part 31 is empty or the weight on the front tread part 31 is not greater than the weight limit (for example, but not limited to, the conventional maximum weight of the birds in the current use environment), the bin cover 2 is in the upward flipped state, and the opening of the feeding port 12 is open to allow the bird food to be eaten. If the weight on the front tread part 31 is greater than the predetermined weight limit, for example, if the object currently located on the front tread part 31 is a squirrel or a mouse or other heavier animals, the front tread part 31 is flipped downward under the action of gravity, the two rear connecting rods 32 are synchronously rotated downward, the rear connecting rod 32 drives the linkage mechanism 4 to further drive the bin cover 2 to flip downward, and the bin cover 2 closes the opening of the feeding port 12 to prohibit the bird food to be eaten. After the squirrel or the heavier animal leaves, the weight of the front tread part 31 decreases, the front tread part 31 is reset, and the bin cover 2 is reset to the upward flipped state to reopen the opening of the feeding port 12.

[0060] From the above, the bird feeder of the present embodiment can automatically flip the bin cover 2 according to the weight of the object on the front step 31, automatically close the opening of the feeding port 12, avoid the animals such as squirrels and mice from stealing the food at the feeding port, and reduce the loss of bird food. At the same time, it is beneficial to the reset of the bin cover 2 and ensures the feeding of birds. The bird feeder of the present embodiment has a clever and reasonable structure, good usability, and wide application range.

[0061] As an illustration of the present embodiment, a specific linkage mechanism 4 implementation is further provided.

[0062] Each linkage mechanism 4 includes a shaft sleeve swing arm 41, a hinged connecting rod 42, and an elastic member 43.

[0063] The shaft sleeve swing arm 41 includes a shaft sleeve 411 and a swing arm 412 connected or integrated with the shaft sleeve 411. The end of the shaft sleeve 411 on the inner side of the swing arm 412 is fixedly sleeved with the hinge shaft of the bin cover 2 connected to the first side plate, and is fixedly connected with the hinge shaft of the bin cover 2, thereby driving the bin cover 2 to flip. The swing arm 412 is located on the outer side of the first side plate and has a predetermined gap with the outer side of the first side plate, so that the swing arm 412 can rotate along the shaft sleeve 411 outside the outer side of the first side plate. In the present embodiment, the swing arm 412 is preferably parallel to the outer side of the first side plate. The end of the swing arm 412 opposite to the shaft sleeve 411 is hingedly connected with one end of the hinged connecting rod 42, and the other end of the hinged connecting rod 42 is hingedly connected with a rear connecting rod 32. The hinged connecting rod 42 is hingedly connected between the swing arm 412 and the rear connecting rod 32, and can rotate along the hinge connection portions at both ends. The upper end of the elastic member 43 is fixed to the rear connecting rod 32, and the lower end is fixed to the first side plate on the side where the linkage mechanism 4 is located. The elastic member 43 has an upward pulling force on the movable step 3, suspending the movable step 3 at the front end of the feeding port 12.

[0064] As an illustration of the present embodiment, the elastic member 43 of the present embodiment can be, but is not limited to, a spring, such as, but not limited to, a tension spring, the upper end of which is fastened to the first side plate, and the lower end of which is fastened to the corresponding rear link. Wherein, the hinged connection point of the first side plate and the rear link 32, the fixed connection point of the elastic member 43 and the rear link 32, and the hinged connection point of the hinged connecting rod 42 and the rear link 32, are arranged in sequence from back to front on the rear link 32. The elastic force of the elastic member 43 is adjusted so that when the front tread 31 is empty or the weight on the front tread 31 is not greater than the predetermined limit weight (i.e. in normal state), the tension of the elastic member 43 and the force of the hinged connection part of the rear link 32 make the movable tread 3 balanced in force and maintain a horizontal or approximately horizontal state at the front end of the opening of the feeding port 12, at this time the cover 2 is in an upwardly turned state, the opening of the feeding port 12 is in an open state, and at this time the bird feeder is in an open state; when the weight on the front tread 31 is greater than the predetermined limit weight, the movable tread 3 is unbalanced in force, the gravity is greater than the tension of the elastic member 43, the front tread 31 is turned downward, the two rear links 32 are rotated downward, the lower end of the hinged connecting rod 42 moves downward and rearward, the hinged connecting rod 42 drives the swing arm 412 to move downward and forward, the swing arm 412 drives the shaft sleeve 411, the shaft sleeve 411 drives the hinged shaft of the cover 2 to rotate, the cover 2 is turned downward, the cover 2 closes the opening of the feeding port 12, at this time the bird feeder is in a non-open state. When the weight on the front tread 31 is removed, the elastic member 43 is self-adapted to shorten and pull the movable tread back to the original open state of the front tread 31 to facilitate the birds to eat again.

[0065] Referring to the drawings, the present embodiment is provided with two linkage mechanisms 4, one on each side of the feeding port 12, which is beneficial to better improve the balance of the movement of the movable tread 3 and improve the stability and flexibility of the mechanism. However, in practice, it is not limited to this, in theory, the linkage mechanism 4 can be, but is not limited to, provided on one side of the feeding port 12, and on the other side of the feeding port 12: the rear link 32 is hinged to the side plate of the feeding port 12, and the cover 2 is hinged to the side plate of the feeding port 12, so that they can rotate flexibly following the components on the side provided with the linkage mechanism 4, which can also achieve the linkage target of the present application.

[0066] In addition, in the bird feeder of the present embodiment, the linkage mechanism 4 of the present embodiment is used, the length of the rear link 32 can be adjusted, the front tread 31 is turned at a smaller angle, through the linkage of the hinged connecting rod 42 and the shaft sleeve swing arm 41, the cover 2 can be driven to turn at a larger angle, the opening and closing speed of the cover 2 is improved, and the effect of high sensitivity gravity sensing automatic opening and closing of the cover 2 is achieved.

[0067] In summary, by using the linkage mechanism 4 of the embodiment, the front step 31 can be linked to open / close the cover 2 by a few times of angle with a very small angle of the rear connecting rod 32, which is an innovative, efficient and stable mechanism.

[0068] As an example of the embodiment, the bird feeder further comprises a camera 5 and an antenna 6 electrically connected with the camera 5. The camera 5 is arranged to face the front step 31 and capture images of the front step 31.

The rear frame 13 is provided with the bin 11 having an opening at the front end, and the bin 11 extends forward to form the feeding opening 12 at the front end. The front frame 14 is shaped to match the opening of the bin 11 and is used to seal the bin 11. Thus, the front frame 14 can be removed to add bird food through the opening of the bin 11, and the front frame 14 can be installed to seal the bin 11 after the bird food is added, which protects the bird food and improves the storage effect.

[0070] As an example of the embodiment, the bin 11 and the front frame 14 can be assembled by setting grooves 15 (or protrusions) on the inner walls of the bin 11 and setting protrusions (or grooves) on the edges of the front frame 14, so that the protrusions of the bin 11 and the front frame 14 are located in the corresponding grooves 15 to achieve the packaging of the front frame.

[0071] As an example of the embodiment, the front frame 14 can be provided with a chamber having an opening at the front end, and the camera 5 is installed in the chamber. This design is beneficial to protect the camera 5 from damage caused by collision and is more conducive to image capture.

[0072] As an example of the embodiment, the main frame 1 is further provided with a solar panel 7, and the area of the solar panel 7 is wider than that of the bird feeder (including the main frame 1 and the movable step 3). On the one hand, the solar panel 7 can protect the bird feeder from wind and rain.

[0073] In addition, the solar panel 7 is electrically connected with the camera 5 and the antenna 6 to supply power for the camera 5 and the antenna 6, without the need for external power supply or battery, which makes the bird feeder more suitable for outdoor application environment.

[0075] As an embodiment of the present application, the bottom of the main frame 1 is further provided with a downward hole column, the inner diameter of the hole column linearly changes from narrow to wide from top to bottom, and the inner wall of the hole column at the bottom of the main frame 1 is inclined from top to bottom, that is, the internal space is a tapered shape with narrow top and wide bottom, such as but not limited to a circular cone or a circular truncated cone (a circular cone with a top part removed).

[0076] The bottom plate 81 of the fixing part 8 is further provided with an internal thread 83 for installing a fastening nut 17. The fastening nut 17 is provided with a first insertion pipe part 18 penetrating from top to bottom for inserting the external plug-in part 9, the inner diameter of the first insertion pipe part 18 is used for inserting the external plug-in part 9, and the outer diameter of the first insertion pipe part 18 linearly changes from narrow to wide from top to bottom, that is, the outer shape of the first insertion pipe part 18 is a tapered shape with narrow top and wide bottom, such as but not limited to a circular cone or a circular truncated cone (a circular cone with a top part removed).

[0077] The first insertion pipe part 18 is provided with a plurality of gaps 19 penetrating the pipe wall, each gap 19 extends upward from the lower end of the first insertion pipe part 18 and penetrates the top of the first insertion pipe part 18, so that the upper part of the first insertion pipe part 18 is separated into petals by the gaps 19, and the size and shape of each petal can be the same or different. The plurality of gaps 19 are designed so that the upper part of the first insertion pipe part 18 can be tightened under the action of a compression force to compress the external plug-in part 9 inserted therein.

[0078] As an embodiment of the present application, a hollow insertion pipe with a circular shape that is easy to insert into an empty field or grassland can be used as the external plug-in part 9, which is labor-saving on one hand and helps to reduce the weight of the intelligent bird feeder and improve the assembly firmness on the other hand. In summary, the fastening structure of the present application is a simple and efficient locking structure, and the application of the structure is helpful to improve the assembly firmness of the intelligent bird feeder. The user inserts the bird feeder into the hollow pipe in the grassland, and the bird feeder stands in the center of the grassland.

[0079] The application principle of the above structure is that the external plug-in 9 is inserted into the first insertion pipe part 18 in the fastening nut 17, the upper part of the external plug-in 9 is completely inserted into the upper part of the first insertion pipe part 18 (which can be at the same level or almost at the same level or slightly higher than the upper part of the first insertion pipe part 18), when the fastening nut 17 is screwed into the internal thread 83 from the bottom surface of the bottom plate 81 of the fixed part 8, with the screwing of the fastening nut 17, the upper part of the first insertion pipe part 18 enters the inner hole of the inner hole column of the main frame 1, the outer wall of the upper part of the first insertion pipe part 18 is attached to the inner wall of the inner hole column, the inclined inner wall of the inner hole column of the main frame 1 has pressure on the inclined outer wall of the first insertion pipe part 18, under the action of the pressure, the gap 19 of the upper part of the first insertion pipe part 18 is narrowed, the first insertion pipe part 18 is deformed inwardly and tightened, and the first insertion pipe part 18 tightly presses the external plug-in 9 located therein. And since the outer diameter of the first insertion pipe part 18 and the inner diameter of the inner hole column of the bottom part of the main frame 1 are linearly changed from narrow at the top to wide at the bottom, as the fastening nut 17 is further screwed in, the pressure of the inclined inner wall of the inner hole column on the corresponding inclined outer wall of the first insertion pipe part 18 is increasingly strengthened, the first insertion pipe part 18 is increasingly deformed inwardly and tightened, and the first insertion pipe part 18 increasingly tightly presses the external plug-in 9 located therein, further fastening the external plug-in 9.

[0080] As an example of the present embodiment, a plurality of upper and lower hollow hole parts are provided on the front step part 31 of the bird feeder of the present embodiment, so that the leaked bird food or rainwater does not accumulate thereon but falls from the hollows.

[0081] As an example of the present embodiment, the front step part 31 of the present embodiment can be a step plate or a horizontal rod. An arc-shaped smooth curved surface can be provided on the top of the front step part 31 to facilitate the cleaning of the top surface.
