[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0015] Depend on Figures 1 to 4 It can be known that an independent cabinet with electric opening without an upper box includes a cabinet body 1, a cabinet door 2 is provided at the front end of the cabinet body 1, an upper opening mechanism connected to the upper part of the cabinet door 2 and a lower opening mechanism connected to the lower part of the cabinet door 2 are provided in the cabinet body 1, the upper opening mechanism includes a motor 3 fixed on the top of the cabinet body 1, the motor 3 is transmission-connected to a transmission shaft 4 connected to the cabinet door 2, the motor 3 controls the change of the distance between the upper part of the cabinet door 2 and the cabinet body 1, the lower opening mechanism includes an electric push rod 5 arranged at the bottom of the cabinet body 1, the electric push rod 5 is connected to the lower part of the cabinet door 2, the electric push rod 5 controls the change of the distance between the lower part of the cabinet door 2 and the cabinet body 1, a first slide rail 6 is provided between the upper opening mechanism and the cabinet body 1, a second slide rail 7 is provided between the lower opening mechanism and the cabinet body 1, and the cabinet door 2 can slide open.
[0016] When the utility model is used in practice, the cabinet door 2 can be extended and retracted forward and backward relative to the cabinet body 1, and can also slide left and right. When the cabinet door 2 is closed with the cabinet body 1, the cabinet door 2 needs to slide forward before it can slide left and right to open. When the cabinet door 2 is opened, the upper opening mechanism and the lower opening mechanism operate synchronously, so that the upper and lower parts of the cabinet door 2 are opened synchronously. When the cabinet door 2 moves forward to a certain position, the cabinet door 2 can slide to one side to make way for the front end of the cabinet body 1, so as to take and put exhibition items into the cabinet body 1.
[0017] In order to open the cabinet door 2, the specific structure of the upper opening mechanism is as follows: a track spotlight 8 is provided at the top of the cabinet body 1, the motor 3 is located behind the top of the cabinet body 1, the transmission shaft 4 is located at the top edge of the cabinet body 1, and the output shaft of the motor 3 is connected to the transmission shaft 4 via a coupling 9, a commutator 10, and a screw 11, and a first sensor 12 is provided on the transmission shaft 4.
[0018] The motor 3 adopts a double-headed motor 3, which is connected to the transmission rod through a coupling 9, and realizes 90° transmission through the commutator 10 located at the corner of the cabinet 1, driving the screw 11 to rotate, so that the transmission shaft 4 can achieve forward and backward displacement. The transmission shaft 4 is connected to the first slide rail 6, and the displacement of the transmission shaft 4, that is, the opening range of the upper part of the cabinet door 2, is controlled by the first sensor 12.
[0019] The double-headed motor 3 enables both sides of the upper part of the cabinet door 2 to achieve forward and backward displacement synchronously, which is more stable and more synchronous.
[0020] The lower opening mechanism also includes a linear bearing 13 connecting the cabinet body 1 and the second slide rail 7. The linear bearing 13 is used to provide a telescopic track for the lower part of the cabinet door 2. A second sensor 14 is provided in the cabinet body 1. The second sensor 14 is used to detect the position of the lower opening mechanism.
[0021] The lower opening mechanism is provided with thrust by the electric push rod 5, which pushes the second slide rail 7 to slide back and forth along the linear bearing 13. The position of the second slide rail 7, that is, the opening amplitude of the lower part of the cabinet door 2, is determined by the second sensor 14, so that it keeps synchronization with the upper part of the cabinet door 2. The electric push rod 5 is located in the middle position of the cabinet body 1, so that the left and right sides of the cabinet door 2 are evenly stressed when moving forward and backward, and the synchronization is better.
[0022] The second slide rail 7 adopts a pulley linear track to provide sufficient supporting force for the cabinet door 2 under the premise of ensuring sliding, thereby preventing the cabinet door 2 from deforming.
[0023] Compared with the prior art, the utility model has the following beneficial effects: the cabinet door is opened by means of an upper and lower double opening mechanism, the upper part of the cabinet door is opened by a double-headed motor driving the lead screws on both sides at the same time, and the lower part is opened by an electric push rod driving method; the opening amplitude of the cabinet door is controlled by sensors at the upper and lower parts, thereby ensuring the synchronization of the cabinet door opening.
