Technical Field
[0001] This utility model relates to the field of hinge technology, specifically to a hydraulic electric hinge. Background Technology
[0002] Hinges are common metal fittings that connect two parts of furniture and enable their movement. Their main function is to support and secure furniture components, allowing them to rotate automatically within a certain range. Hydraulic hinges are among the most advanced types.
[0003] However, most common hydraulic hinges use a single power spring for driving force, resulting in a uniform opening and closing force. This makes the hinge's opening and closing experience indistinguishable. Some hydraulic hinges, in order to differentiate the opening and closing speed and force, use independent hydraulic buffer circuits for opening and closing. This increases costs, makes the structure more complex, and leads to difficulties in later maintenance and high maintenance costs.
[0004] Therefore, a new hydraulic hinge is urgently needed. Utility Model Content
[0005] This invention proposes a hydraulic electric hinge, which solves the problems of difficult maintenance and high cost caused by the complex structure of existing hydraulic hinges.

[0007] A first base is provided on the door frame, and a first receiving cavity is provided inside the first base;
[0008] A hydraulic drive component is mounted on the first base and embedded within the door frame;
[0009] A rotary hydraulic cylinder is disposed within the first accommodating cavity and connected to the hydraulic drive component;
[0010] The first rocker arm is connected to the output end of the rotary hydraulic cylinder and rotates with the rotary hydraulic cylinder;
[0011] A second base is provided on the door body, and a second receiving cavity is provided inside the second base;
[0012] The second rocker arm is disposed within the second accommodating cavity;
[0013] The third rocker arm is hinged at one end to the first rocker arm and at the other end to the second rocker arm;
[0014] The rotary hydraulic cylinder achieves the rotation of the first base relative to the second base by means of the first rocker arm, the second rocker arm, and the third rocker arm.
[0015] As a further technical solution, the hydraulic drive component includes:
[0016] The motor is mounted on the first base;
[0017] The pump body is mounted on the first base and connected to the motor;
[0018] The hydraulic pipe is connected at one end to the pump body and at the other end to the rotating hydraulic cylinder.
[0019] As a further technical solution, the hydraulic drive component also includes a one-way throttle valve, which is disposed on the hydraulic pipe.
[0020] As a further technical solution, the hydraulic drive component also includes a two-way safety valve, which is disposed on the hydraulic pipe and located between the one-way throttle valve and the pump body.
[0021] As a further technical solution, a protective shell is also included, which is connected to the first base, and a protective space is formed between the protective cover and the first base, with the hydraulic drive component located within the protective space.
[0022] As a further technical solution, the first base is embedded in the door frame.
[0023] As a further technical solution, the second base is embedded in the door body.
[0024] As a further technical solution, the first base includes:
[0025] The first bottom shell is embedded in the door frame, and the first receiving cavity is located on the first bottom shell;
[0026] The first fixed frame is detachably fixed inside the first bottom shell, and the rotating hydraulic cylinder is connected to the first fixed frame;
[0027] The first cover plate is fitted onto the first bottom shell and covers the connection between the first bottom shell and the first fixing frame.
[0028] As a further technical solution, the second base includes:
[0029] The second bottom shell is embedded in the door body, and the second accommodating cavity is located inside the second bottom shell;
[0030] The second fixing frame is detachably fixed inside the second bottom shell, and the second rocker arm is mounted on the second fixing frame;
[0031] The second cover plate is fitted onto the second bottom shell and covers the connection between the second bottom shell and the second fixing frame.
[0032] As a further technical solution, the third rocker arm is hinged to the middle part of the first rocker arm and the second rocker arm respectively.
[0033] The working principle and beneficial effects of this utility model are as follows: The hydraulic electric hinge includes a first base, a hydraulic drive component, a rotary hydraulic cylinder, a first rocker arm, a second base, a second rocker arm, and a third rocker arm. The first base is mounted on the door frame, and the second base is mounted on the door body. The door body and door frame are a combined unit. The first base has a first receiving cavity, and the second base has a second receiving cavity. The rotary hydraulic cylinder is located within the first receiving cavity. The hydraulic drive component is mounted on the first base and connected to its output end. The first rocker arm is connected to the output end of the rotary hydraulic cylinder. A portion of the first rocker arm is located within the first receiving cavity, and the second rocker arm is located within the second receiving cavity. One end of the third rocker arm is hinged to the first rocker arm, and the other end is hinged to the second rocker arm. Under the action of the hydraulic drive, the rotating hydraulic cylinder rotates, which in turn causes the first rocker arm to swing. The swing of the first rocker arm causes the third rocker arm to swing, which in turn causes the second rocker arm to swing. Since the second rocker arm is mounted on the second base, the second base swings relative to the rotating hydraulic cylinder. Since the rotating hydraulic cylinder is connected to the first base, this realizes the rotation of the second base relative to the first base, and ultimately realizes the rotation of the door body relative to the door frame, that is, realizes the opening and closing of the door body.
[0034] Because the overall structure of the hydraulic electric hinge provided by this utility model is relatively simple, and only the first rocker arm and the second rocker arm are exposed to the outside, and the hydraulic drive components exist in a modular manner, the overall maintenance is relatively simple and the replacement cost is also low.

[0051] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0052] like Figures 1-10 As shown, this embodiment proposes a hydraulic-electric hinge, comprising:
[0053] A first base 1 is disposed on the door frame, and a first receiving cavity is provided inside the first base 1;
[0054] The hydraulic drive component 2 is mounted on the first base 1 and embedded in the door frame;
[0055] A rotary hydraulic cylinder 3 is disposed in the first accommodating cavity and connected to the hydraulic drive component 2;
[0056] The first rocker arm 4 is connected to the output end of the rotary hydraulic cylinder 3 and rotates along with the rotary hydraulic cylinder 3;
[0057] The second base 5 is installed on the door body, and the second base 5 has a second receiving cavity inside;
[0058] The second rocker arm 6 is disposed within the second accommodating cavity;
[0059] The third rocker arm 7 is hinged at one end to the first rocker arm 4 and at the other end to the second rocker arm 6.
[0060] The rotary hydraulic cylinder 3 achieves the rotation of the first base 1 relative to the second base 5 by means of the first rocker arm 4, the second rocker arm 6 and the third rocker arm 7.
[0061] In this embodiment, the hydraulic electric hinge includes a first base 1, a hydraulic drive 2, a rotary hydraulic cylinder 3, a first rocker arm 4, a second base 5, a second rocker arm 6, and a third rocker arm 7. The first base 1 is mounted on the door frame, and the second base 5 is mounted on the door body. The door body and door frame are a combined unit. The first base 1 has a first receiving cavity, and the second base 5 has a second receiving cavity. The rotary hydraulic cylinder 3 is located within the first receiving cavity. The hydraulic drive 2 is mounted on the first base 1 and connected to its output end. The first rocker arm 4 is connected to the output end of the rotary hydraulic cylinder 3, with a portion of it located within the first receiving cavity. The second rocker arm 6 is located within the second receiving cavity. One end of the third rocker arm 7 is hinged to the first rocker arm 4, and the other end is hinged to the second rocker arm 6. Under the action of the hydraulic drive component 2, the rotating hydraulic cylinder will rotate, which in turn will cause the first rocker arm 4 to swing. The swing of the first rocker arm 4 will cause the third rocker arm 7 to swing, which in turn will cause the second rocker arm 6 to swing. Since the second rocker arm 6 is mounted on the second base 5, the second base 5 swings relative to the rotating hydraulic cylinder. Since the rotating hydraulic cylinder is connected to the first base 1, this realizes the rotation of the second base 5 relative to the first base 1, and finally realizes the rotation of the door body relative to the door frame, that is, realizes the opening and closing of the door body.
[0062] Since the hydraulic electric hinge provided by this utility model has a relatively simple overall structure, and only the first rocker arm 4 and the second rocker arm 6 are exposed to the outside, and the hydraulic drive component 2 exists in a modular manner, the overall maintenance is relatively simple and the replacement cost is also low.
[0063] Furthermore, such as Figures 6-7 As shown, this embodiment proposes a hydraulic drive component 2 including:
[0064] Motor 21 is mounted on the first base 1;
[0065] Pump body 22 is mounted on first base 1 and connected to motor 21;
[0066] The hydraulic pipe 23 is connected at one end to the pump body 22 and at the other end to the rotating hydraulic cylinder.
[0067] In this embodiment, the hydraulic drive component 2 includes a motor 21, a pump body 22, and a hydraulic pipe 23. Both the motor 21 and the pump body 22 are mounted on the first base 1, with the output end of the motor 21 connected to the input end of the pump body 22. One end of the hydraulic pipe 23 is connected to the pump body 22, and the other end is connected to a rotating hydraulic cylinder. Both the hydraulic pipe 23 and the pump body 22 store hydraulic oil. The rotation of the motor 21 causes the pump body 22 to move, guiding the flow of hydraulic oil and thus rotating the hydraulic cylinder. When the motor 21 rotates in different directions, the flow direction of the hydraulic oil in the hydraulic pipe 23 is inconsistent, causing the rotating hydraulic cylinder to rotate in both directions, ultimately opening and closing the door relative to the door frame.
[0068] Furthermore, such as Figures 6-7 As shown in the figure, this embodiment proposes that the hydraulic drive component 2 also includes a one-way throttle valve 24, which is disposed on the hydraulic pipe 23.
[0069] In this embodiment, to adjust and control the door opening speed, the hydraulic drive unit 2 also includes a one-way throttle valve 24, which is installed on the hydraulic pipe 23. By changing the throttling cross-section and length, the one-way throttle valve 24 can control the flow rate inside the system. When the liquid flows in the forward direction, the liquid is throttled through the one-way throttle valve 24; when it flows in the reverse direction, the one-way throttle valve 24 opens and does not throttle, thereby controlling the flow direction of the internal liquid. Since a low speed is required when closing the door, the one-way throttle valve 24 is used for control, which ensures that the door opens quickly and then closes slowly.
[0070] Furthermore, such as Figures 6-7 As shown, this embodiment proposes that the hydraulic drive component 2 also includes a two-way safety valve 25, which is disposed on the hydraulic pipe 23 and located between the one-way throttle valve 24 and the pump body 22.
[0071] In this embodiment, in order to reduce the pressure in the hydraulic pipe 23, a two-way safety valve 25 is also provided on the hydraulic pipe 23. The two-way safety valve 25 can ensure that the rotary hydraulic cylinder 3, the motor 21 and the pump body 22 operate within the normal working pressure range.
[0072] Furthermore, such as Figures 6-7As shown, this embodiment also includes a protective shell 8, which is connected to the first base 1. A protective space is formed between the protective cover and the first base 1, and the hydraulic drive component 2 is located within the protective space.
[0073] In this embodiment, in order to prevent the motor 21 and pump body 22 from being damaged, a protective shell 8 is also provided. The protective shell 8 is connected to the first base 1. The protective shell 8 has an internal recess, and a protective space is formed between the recess and the first base 1. The motor 21, pump body 22, hydraulic pipe 23, one-way throttle valve 24 and two-way safety valve 25 are all located in the protective space, so as to prevent the hydraulic drive component 2 from being subjected to external impact and damage during normal use.
[0074] Furthermore, such as Figure 10 As shown in the figure, this embodiment proposes that the first base 1 is embedded in the door frame and the second base 5 is embedded in the door body.
[0075] In this embodiment, in order to ensure the stability of the operation of the hydraulic electric hinge, the first base 1 is embedded in the door body and the second base 5 is embedded in the door body. At this time, the third rocker arm 7 is completely exposed to the outside of the door body and the door frame.
[0076] Furthermore, such as Figures 8-9 As shown, this embodiment proposes a first base 1 including:
[0077] The first bottom shell 11 is embedded in the door frame, and the first receiving cavity is located on the first bottom shell 11;
[0078] The first fixed frame 12 is detachably fixed inside the first bottom shell 11, and the rotating hydraulic cylinder is connected to the first fixed frame 12;
[0079] The first cover plate 13 is fitted onto the first bottom shell 11 and covers the connection between the first bottom shell 11 and the first fixing frame 12.
[0080] In this embodiment, for convenient maintenance, the first base 1 includes a first bottom shell 11, a first fixing frame 12, and a first cover plate 13. The first bottom shell 11 is embedded within a door frame, a first accommodating cavity is located on the first bottom shell 11, the first fixing frame 12 is disposed within the first accommodating cavity, and the first fixing frame 12 and the first bottom shell 11 are detachably connected. A rotating hydraulic cylinder is connected to the first fixing frame 12, and the first cover plate 13 is engaged with the first bottom shell 11, covering the connection between the first bottom shell 11 and the first fixing frame 12. This not only allows for rapid disassembly and replacement but also extends the service life of the first base 1.
[0081] Furthermore, such as Figures 8-9 As shown, this embodiment proposes a second base 5 including:
[0082] The second bottom shell 51 is embedded in the door body, and the second receiving cavity is located inside the second bottom shell 51;
[0083] The second fixing frame 52 is detachably fixed inside the second bottom shell 51, and the second rocker arm 6 is mounted on the second fixing frame 52.
[0084] The second cover plate 53 is fitted onto the second bottom shell 51 and covers the connection between the second bottom shell 51 and the second fixing frame 52.
[0085] Similarly, in this embodiment, to facilitate maintenance and replacement of parts, the second base 5 includes a second bottom shell 51, a second fixing bracket 52, and a second cover plate 53. The difference is that the second bottom shell 51 is embedded within the door body.
[0086] Furthermore, such as Figures 1-2 As shown, in this embodiment, the third rocker arm 7 is hinged to the middle part of the first rocker arm 4 and the second rocker arm 6 respectively.
[0087] In this embodiment, the third rocker arm 7 is hinged to the middle of the first rocker arm 4 and the second rocker arm 6, which can improve the stable connection of the first rocker arm 4, the second rocker arm 6 and the third rocker arm 7, and also ensure the effectiveness of force transmission. In addition, choosing the middle of the first rocker arm 4 and the second rocker arm 6 as the hinge point can ensure the rigidity of the assembly of the first rocker arm 4, the second rocker arm 6 and the third rocker arm 7.
[0088] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
