[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] According to the attached Figures 1 to 4As shown in the figure, the oven hinge with the function of stopping when encountering an obstacle of the present invention comprises a fixing seat 1 and a connecting arm 2 respectively installed on the box body and the door body, and a transmission component is hinged between the fixing seat 1 and the connecting arm 2. Among them, the transmission component comprises a transmission connecting rod group 3. The transmission connecting rod group 3 is provided with a power source for the door body to automatically open and close in the box body, and the power source comprises a motor 4 and a transmission protection member. The motor 4 is installed on one side of the box body and is transmission-connected to the transmission connecting rod group 3. The transmission protection member is connected to the motor 4 and can control the stop of work according to the sudden change of the speed of the motor 4 deviating from the speed curve of the door opening and closing.

[0024] Reference Figures 1 to 4 As shown, the transmission protection member further comprises a protection sensor 5 and a connecting rod 6. The front end of the connecting rod 6 is connected to the transmission connecting rod group 3, the rear end of the connecting rod 6 is transmission-connected to the output end of the motor 4, and the protection sensor 5 is signal-connected to the motor 4.

[0025] That is, when the door is open, the motor 4 is working, and the motor 4 drives the transmission link group 3 to move forward through the connecting rod 6, so as to drive the connecting arm 2 to swing downward, so as to realize the automatic downward movement of the door. When a person blocks the door, the protection sensor 5 detects that the speed of the motor 4 suddenly changes and deviates from the speed curve of the motor 4 when opening the door, and feeds back the corresponding information to control the motor 4 to stop working.

[0026] Similarly, when the door is closed, the motor 4 drives the transmission link group 3 to move backward through the connecting rod 6, so as to drive the connecting arm 2 to swing upward, so as to realize the automatic upward movement of the door. When the door is blocked by hand, the protection sensor 5 detects that the speed of the motor 4 suddenly changes and deviates from the speed curve of the motor 4 for opening the door, and feeds back the corresponding information to control the motor 4 to stop working.

[0027] Through the structural coordination of the transmission connecting rod group 3, the motor 4 and the transmission protection part, when encountering resistance during the opening and closing of the door body, the transmission protection part can feedback the corresponding information according to the sudden deviation of the motor 4 speed from the door opening and closing speed curve, so that the motor 4 stops moving immediately and the door body stops at the current position. It is safe and practical, and reduces safety hazards such as pinching hands.

[0028] Reference Figures 1 to 4 As shown, in further detail, a detachable engaging portion 7 is connected between the end of the transmission connecting rod group 3 and the front end of the connecting rod 6, and a buckle 8 is installed on the engaging portion 7. The assembly is simple, the disassembly is easy, and the maintenance is convenient.

[0029] The box body is provided with a connecting frame 9, the motor 4 is matched and installed on one side of the connecting frame 9, and a protection sensor 5 is installed in the connecting frame 9. The fixing seat 1 can be disassembled and assembled in the connecting frame 9 by screws 10, and the connecting rod 6 can be connected in the connecting frame 9 by sliding forward and backward in a straight line as the connecting arm 2 swings.

[0030] In practical applications, a guide rod 11 that slides on the connecting frame 9 by swinging along with the connecting arm 2 is installed on the transmission link group 3, and guide grooves 12 for sliding with the guide rod 11 are respectively formed on both sides of the connecting frame 9.

[0031] The structure that cooperates with the connecting frame 9, the transmission link group 3, and the connecting rod 6 is simple in assembly and high in transmission stability, ensuring the use quality of the product.

[0032] Refer to Figures 1 to 4 As shown, for further refinement, the transmission link group 3 is provided with a buffer spring 13. The buffer spring 13 is sleeved on the rear part of the transmission link group 3, and the two elastic ends of the buffer spring 13 are respectively elastically connected to the fixed seat 1 and the transmission link group 3.

[0033] Under the action of the buffer spring 13, the structure is simple, and a buffering effect is added during the opening and closing of the door body, improving the use effect of the product.
