Description
Technical Field
[0001] This utility model relates to the field of elevator technology, specifically to a combination structure of a car wall module and an elevator door frame. Background Technology
[0002] The front wall of an elevator car is usually equipped with a car door for passengers and goods to enter and exit. It is typically composed of a door frame assembly and car wall modules located on the left and right sides of the door frame assembly.
[0003] Referring to the technical solution disclosed in application number 202311254150.0, a modular elevator car is provided in which a first sliding groove is provided at the lower end of the upper crossbar on the front side of the car frame, and a second sliding groove is provided at the upper end of the lower crossbars at both ends of the front side of the car frame. The upper and lower ends of the two front wall components are respectively slidably fitted into the corresponding first and second sliding grooves. In addition, the second decorative piece is an L-shaped structure, and the first right-angled edge of the second decorative piece is pressed against the front end face of the outer side of the front wall component. The second right-angled edge of the second decorative piece is attached to the outer side wall of the corresponding front column by self-tapping screws. Elastic rubber strips are provided on both the front and rear sides of the front wall component near the end of the second decorative piece. The elastic rubber strips on the front and rear sides of the front wall component abut against the corresponding front column and the right-angled edge of the second decorative piece, respectively, to realize the left and right limit of the front wall component.
[0004] However, despite the significant advancements in design and assembly of this technical solution, the elevator car is inevitably subject to vibration during actual operation. This vibration may potentially affect the installation stability of the front wall components. In particular, the elastic rubber strips, subjected to vibration and compression during elevator operation over a long period, may deform, age, or even fail. This would significantly reduce the limiting effect of the elastic rubber strips on the front wall components, potentially leading to unstable movement or swaying of the front wall components during elevator operation. This would not only affect the elevator's ride comfort but could also damage the overall structure of the elevator car, reducing the elevator's safety and lifespan. Utility Model Content

The front wall frame includes two column assemblies 3, an upper crossbar assembly 4, and two lower crossbar assemblies 5. The upper crossbar assembly 4 is located between the upper parts of the two column assemblies 3, and its left and right ends are respectively inserted into the car wall clamping grooves of the two column assemblies 3. The upper part of the upper crossbar assembly 4 is fixedly connected to the bottom of the car top plate 6 by a car top bolt assembly, and the lower part is fixedly connected to the upper part of the door frame assembly 1. The two lower crossbar assemblies 5 are respectively located at the lower parts of the left and right sides of the door frame assembly 1. The lower part of the lower crossbar assembly 5 is fixedly connected to the top of the car bottom plate 7 by a car bottom bolt assembly. One end of the lower crossbar assembly 5 extends and is connected to a column assembly 3, and the other end extends and is connected to the door frame assembly 1.
[0026] Furthermore, the car wall module 2 includes a car wall frame 21 and a transparent glass 22 disposed within the car wall frame 21. Specifically, the middle of the car wall frame 21 is a glass mounting opening, and the edge of the glass mounting opening is a glass slot for inserting the edge of the transparent glass 22. The edge of the transparent glass 22 can be locked and fixed in the glass slot using glass glue and / or adhesive pads, thereby completing the installation of the transparent glass 22. The two ends of the car wall frame 21 are a door frame mating end 201 and a column mating end 202, respectively.
[0027] Furthermore, the door frame assembly 1 includes two door frame pillars 11, a lintel 12 connected to the top of the two door frame pillars 11, and a pedal support beam 13 connected to the bottom of the two door frame pillars 11.

The door frame pillars 11, the lintel 12, and the pedal support beam 13 together form the car doorway.
[0028] Furthermore, a car wall module 2 is provided between the door frame column 11 and the column assembly 3. The outer side of the door frame column 11 has a car wall positioning groove. The top of the car wall module 2 engages with the bottom of the upper crossbar assembly 4, and the bottom engages with the top of the lower crossbar assembly 5, thereby restricting the vertical movement of the car wall module 2 by the upper crossbar assembly 4 and the lower crossbar assembly 5. The door frame engaging end 201 is inserted into the car wall positioning groove, and the column engaging end 202 is clamped in the car wall clamping groove of the column assembly 3. The car wall positioning groove includes features for restricting the car wall... The module 2 has a lateral movement limiting surface 111 for left and right movement and a forward movement limiting surface 112 for limiting the forward movement of the car wall module 2.

One end of the first pressing member 8 is connected to the door frame column 11, and the other end is connected to the door frame mating end 201 and presses the end face of the door frame mating end 201 against the lateral movement limiting surface 111, thereby allowing the first pressing member 8 and the lateral movement limiting surface 111 to limit the left and right movement of the car wall module 2, ensuring the installation stability of the car wall module 2.
[0029] This utility model effectively restricts the left and right movement of the car wall module 2 during elevator operation by clamping one side of the car wall frame 21 together with the first clamping member 8 and the transverse movement limiting surface 111. This significantly enhances the installation stability of the car wall module 2 and avoids unstable movement or shaking caused by vibration. At the same time, it helps to maintain the overall structural strength of the elevator car, prevents potential damage to the car structure caused by the shaking of the car wall module 2, extends the service life of the elevator, and reduces the safety risks caused by malfunctions.
[0030] In a preferred embodiment, the door frame pillar 11 and the lintel 12, as well as the door frame pillar 11 and the pedal support beam 13, are connected by door frame L-shaped connectors 14. The outer side of the door frame pillar 11 is provided with a vertical connecting groove 113 running from top to bottom. The lintel 12 and the pedal support beam 13 are both provided with horizontal connecting grooves 100 running from left to right. The vertical end of the door frame L-shaped connector 14 is inserted into the vertical connecting groove 113 and fixedly connected to the door frame pillar 11 by bolts. The horizontal end of the door frame L-shaped connector 14 is inserted into the horizontal connecting groove 100 and fixedly connected to the lintel 12 or the pedal support beam 13 by bolts.
[0031] In a preferred embodiment, the car wall positioning groove is provided with a car wall corner avoidance notch 114. The lateral movement limiting surface 111 and the forward movement limiting surface 112 are arranged in an L-shape. One end of the lateral movement limiting surface 111 and the forward movement limiting surface 112 extends to the car wall corner avoidance notch 114. The car wall corner avoidance notch 114 can avoid the outer corner of the door frame mating end 201, thereby preventing the outer corner of the door frame mating end 201 from interfering with the door frame mating end 201 and the lateral movement limiting surface 111 and the forward movement limiting surface 112.
[0032] In a preferred embodiment, the car wall locking assembly includes a car wall locking bolt assembly 9 on which a first clamping member 8 is mounted on a door frame pillar 11. One end of the car wall locking bolt assembly 9 is fitted onto the first clamping member 8, and the other end is fitted into a door frame vertical connecting groove 113. Specifically, the first clamping member 8 has a door frame connecting hole. The car wall locking bolt assembly 9 includes a car wall locking bolt and a car wall locking nut. The head of the car wall locking bolt is fitted into the door frame vertical connecting groove 113, and the other end passes through the door frame connecting hole and is threaded onto the car wall locking nut.
[0033] In a preferred embodiment, the top view of the first clamping member 8 is Z-shaped. The first clamping member 8 is composed of a locking member connecting part 81, a locking member bending part 82, and a locking member pressing part 83 that are integrally connected in a Z-shape. The door frame connecting holes are opened on the locking member connecting part 81 and there are two from front to back. Each door frame connecting hole corresponds to a door frame vertical connecting groove 113 and a car wall locking bolt assembly 9. The locking member pressing part 83 is configured to extend into the glass mounting opening and press against the inner side of the door frame mating end 201 so that the end face of the door frame mating end 201 is pressed against the transverse movement limiting surface 111.
[0034] In this embodiment, the column assembly 3 includes a corner column, a second clamping member 31, and a decorative cover 32. The corner column includes an L-shaped integrally formed longitudinal split part 33 and a transverse split part 34, and a column inner protrusion 35 protruding at the inner corner position between the longitudinal split part 33 and the transverse split part 34. The longitudinal split part 33 is provided with a side insertion position for inserting the end of the side wall module 200, and the rear side of the transverse split part 34 away from the longitudinal split part 33 is provided with a transverse insertion position for inserting the column mating end 202.
[0035] Furthermore, the second clamping member 31 is fixed to the inner protrusion 35 of the column using a column bolt assembly. One end of the second clamping member 31 has a protruding side clamping part 311 for pressing the column mating end 202 into the horizontal insertion position. The front end of the side clamping part 311 presses against the rear side of the column mating end 202. The horizontal insertion position includes a column mating limiting surface 341 that restricts the forward movement of the column mating end 202. Thus, the side clamping part 311 and the column mating limiting surface 341 form the car wall clamping groove. Furthermore, the decorative cover 32 is snapped onto the second clamping member 31 and surrounds the second clamping member 31 and the column bolt assembly. One end of the decorative cover 32 extends with a front wall pressing edge 321, which presses against the inner side of the column mating end 202. This allows the decorative cover 32 to also apply a certain clamping force to the column mating end 202, further improving the installation quality of the car wall module 2.
[0036] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
