Description

Technical Field

[0001] The present invention relates to the technical field of elevators, in particular to an elevator operating box door assembly and an elevator operating box. Background Art

[0002] Elevator drivers remain an essential role in medical elevator scenarios. They must ensure safe elevator operation and assist passengers in entering and exiting the elevator by correctly operating the driver's independent switches within the control panel's door assembly. Therefore, improving the driver's operational experience is a key issue that needs to be addressed. In existing technologies, the control panel is equipped with floor registration buttons and door opening and closing buttons at a height suitable for human operation. The door assembly is typically located relatively low, typically around 500mm above the ground. The door assembly contains a dedicated interface or buttons for the driver to operate, preventing the driver from operating the panel while standing upright. Furthermore, opening the rear panel protrudes from the control panel, preventing the driver from seeing the interface while standing upright, creating the risk of misoperation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an elevator control box door assembly which is convenient for an elevator driver to observe the operation interface when standing upright.

[0004] To solve the above technical problems, the present invention provides an elevator control box door assembly, comprising a back panel, a front panel, an electrical module, a lock assembly, and a hinge assembly. The electrical module has a first group of buttons and a second group of buttons. The lock assembly is used to lock the front panel and the back panel. The electrical module is fixed to the inner side of the panel.

[0005] When the lock assembly is unlocked, the hinge assembly places the panel in a first position, wherein the first position enables the first group of buttons to be operated and the second group of buttons to be inoperable;

[0006] When the lock assembly is unlocked and the panel is subjected to a downward external force, the hinge assembly places the panel in a second position, wherein both the first group of buttons and the second group of buttons can be operated.

[0007] Preferably, the lock assembly includes a lock core, a connecting rod bracket, and a connecting rod spring; when the lock assembly is locked, the tension of the connecting rod spring causes the connecting rod bracket to be inserted into the lock hole of the electrical module; when the lock core rotates to unlock the lock assembly, the lock core pushes the connecting rod bracket upward, causing the connecting rod bracket to disengage from the lock hole of the electrical module.

[0008] Preferably, the lock core is fixed in an opening of a back plate or a panel.

[0009] Preferably, the hinge assembly includes a hinge, a left torsion spring, a right torsion spring, a first blocking member and a second blocking member; the hinge is used to hinge the back panel and the panel; the left torsion spring is located inside the hinge, and is used to apply a force in the outward opening direction to the panel; the right torsion spring is located outside the hinge, and is used to apply a force in the inward closing direction to the panel after the panel is opened beyond the first position; the first blocking member is fixed at the electrical module, and the second blocking member is fixed at the back panel; the fixed positions of the first blocking member and the second blocking member correspond to each other, so that when the panel is in the first position and there is no outward external force, the further opening of the panel is blocked.

[0010] Preferably, the first blocking member is a spring sheet, and the second blocking member is a boss. When the first blocking member and the second blocking member are in contact, they prevent the panel from opening further through interference fit.

[0011] Preferably, the operating direction of the first group of keys is parallel to the panel, and the operating direction of the second group of keys is perpendicular to the panel.

[0012] The present invention also discloses an elevator operating box, comprising the aforementioned door subassembly.

[0013] Compared with the prior art, the present invention facilitates the elevator driver to observe the operation interface inside the sub-door while standing upright. At the same time, the arrangement of the first group of buttons facilitates the elevator driver to observe and operate the interface while standing almost upright. For example, the first group of buttons can be set with some commonly used function buttons, and the second group of buttons can be set with some less frequently used function buttons.

[0019] The following describes the implementation manner of the present invention through specific specific embodiments. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through different specific implementation manners, and the various details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without deviating from the overall design concept of the invention. It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. The following exemplary embodiments of the present invention can be implemented in a variety of different forms and should not be interpreted as being limited to the specific embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0020] Example 1

[0021] like Figure 1 As shown, this embodiment provides an elevator control box door assembly, including a back panel 1, a panel 2, an electrical module 4, a lock assembly, and a hinge assembly. The electrical module 4 has a first group of buttons 41 and a second group of buttons 42. The lock assembly is used to lock the panel 2 and the back panel 1. The electrical module 4 is fixed to the inner side of the panel 2.

[0022] When the lock assembly is unlocked, the hinge assembly places the panel 2 in a first position, in which the first group of buttons 41 can be operated and the second group of buttons 42 cannot be operated; when the lock assembly is unlocked and the panel 2 is subjected to a downward external force, the hinge assembly places the panel 2 in a second position, in which the first group of buttons 41 and the second group of buttons 42 can both be operated.

[0023] The operating direction of the first group of buttons 41 is parallel to the panel 2 , and the operating direction of the second group of buttons 42 is perpendicular to the panel 2 .

[0024] More specifically, the lock assembly includes a lock core 31, a connecting rod bracket 32, and a connecting rod spring 33; when the lock assembly is locked, the tension of the connecting rod spring 33 causes the connecting rod bracket 32 ​​to be inserted into the lock hole of the electrical module 4; when the lock core 31 rotates to unlock the lock assembly, the lock core 31 pushes the connecting rod bracket 32 ​​upward, causing the connecting rod bracket 32 ​​to disengage from the lock hole of the electrical module 4.

[0025] The lock core 31 can be fixed in the opening of the back plate, such as Figure 1 As shown, it can also be fixed in the opening of the panel, such as Figures 2 to 4 shown.

[0026] Another alternative implementation is that the lock assembly may only include a lock core, and the lock core is used to lock the panel 2 and the back panel 1.

[0027] The hinge assembly includes a hinge hinge 51, a left torsion spring 52, a right torsion spring 53, a first stopper 54 and a second stopper 55; the hinge hinge 51 is used to hinge the back panel 1 and the panel 2; the left torsion spring 52 is located inside the hinge hinge 51, and is used to apply a force in the outward opening direction to the panel; the right torsion spring 53 is located outside the hinge hinge, and is used to apply a force in the inward closing direction to the panel after the panel is opened beyond the first position; the first stopper 54 is fixed to the electrical module 4, and the second stopper 55 is fixed to the back panel 1; the fixed positions of the first stopper 54 and the second stopper 55 correspond to each other, so that when the panel is in the first position and there is no outward external force, the further opening of the panel is blocked.

[0028] The first blocking member 54 is a spring, and the second blocking member 55 is a boss. When the first blocking member 54 and the second blocking member 55 are in contact, they prevent the panel from opening further through interference fit.

[0029] In this embodiment, the door assembly is installed in the control box panel, and the panel 2 is usually integrated with the control box panel. The state of the door assembly is divided into three, such as Figures 2 to 4 shown.

[0030] Figure 2 The panel is in a closed state: the left torsion spring 52 is in a compressed state, and the connecting rod bracket 32 ​​is inserted into the electrical module 4 to prevent the panel 2 from popping outward. Figure 3 The panel is in the first position: the elevator driver turns the key, the lock tongue of the lock cylinder 31 rotates and drives the connecting rod bracket 32 ​​to move upward. When the connecting rod bracket 32 ​​is separated from the opening of the electrical module, the left torsion spring 52 pushes the hinge 51, and the panel and the electrical module pop out at the same time. The panel is kept in the first position through the interference fit between the spring piece 54 and the bosses 55 on both sides of the back panel. The elevator driver can operate the first group of buttons 41 upright on this interface. Figure 4 The panel is in the second position: the elevator driver slightly presses down on the panel 2, causing the spring 54 to disengage from the two side bosses 55, and the entire panel flips outward to the second position. The elevator driver needs to slightly press the panel with one hand to put pressure on the panel. At this time, the right torsion spring 53 is in a compressed state. After releasing the pressure, the panel automatically rebounds to the first position under the action of the right torsion spring 53. The elevator driver can return the panel to its original closed state by slightly pushing on the panel.
