Description

Technical Field

[0001] This utility model relates to the field of home elevator shaft technology, specifically a backpack-style elevator car structure. Background Technology

[0002] With the improvement of living standards, home elevators and villa elevators are increasingly being used. Currently, the most common structures in home elevators are the backpack frame type and the gantry frame type. Backpack frame home elevators typically use an L-shaped backpack frame to support the car. The bottom of the L-shaped backpack frame needs to support the weight of the entire car and passengers. It is usually made by combining profiles to create the bottom bracket, with two vertical beams connected to the rear of the bottom bracket, and multiple connecting crossbeams between the two vertical beams, thus forming the L-shaped backpack frame structure. Compared to the gantry frame elevator structure, the backpack frame elevator has a higher utilization rate of shaft space, and the car's viewing area can be larger, making it more popular with users.

[0003] The structural form of the car and its connection with the backpack frame are particularly important for backpack frame elevators. In existing backpack frame elevator structures, the car top, car bottom, and multiple car walls are generally assembled into an integral structure first, and then installed on the horizontal support base of the backpack frame. This car structure not only makes disassembly troublesome and labor-intensive when car side walls need to be repaired or replaced later, but also results in low maintenance efficiency.

[0004] Alternatively, some elevators are constructed by adding left and right side panels and a car roof to form a car structure. For example, based on the platform elevator structure disclosed in patent CN216038077U, left and right side panels are added to the left and right sides of the passenger platform, and corresponding car roofs are installed on the top of the left and right side panels and the back panel to form a car with an open front. Although this type of car structure is relatively convenient to install and maintain, the left and right side panels and the back panel are generally only connected and fixed at the corners with L-shaped connectors, resulting in low structural strength. Summary of the Invention

[0005] The problem solved by this utility model is to overcome at least one defect in the prior art by providing a backpack-type elevator car structure that is simple in structure, easy to install and maintain, and has a stable connection structure between the car structure and the backpack frame, resulting in high safety.

[0006] To address the aforementioned problems, this utility model provides a backpack-style elevator car structure, comprising a backpack frame and a car assembly. The backpack frame includes a mounting bracket slidably connected to a guide rail and a base horizontally connected to the lower front end of the mounting bracket. The car assembly includes four columns, left and right side panels, a back panel, and a car roof. The four columns are all corner columns, and each of the two right-angled sides of the four columns has a mounting groove on its inner wall. The two ends of the left and right side panels and the back panel in the width direction are respectively fitted into the mounting grooves of the corresponding columns. Each corner of each column is detachably connected to a positioning plate extending vertically and used to press and position the edge of the corresponding side panel or back panel in the width direction within the corresponding mounting groove. The car roof is detachably connected to the top of the four columns, so that the four columns, left and right side panels, and back panel are assembled into a single unit. The rear side wall of the car roof is detachably connected to the upper end of the backpack frame.

[0007] Compared with the prior art, the backpack-style elevator car structure of this utility model has the following advantages:

[0008] In this utility model, the backpack frame and the car body are not completely independent structures. The horizontal support of the backpack frame directly serves as the car floor. Columns are connected to the four corners of the car floor. Left and right side panels are installed between the two front and rear columns on the left and right sides of the car floor, respectively. A back panel is installed between the left and right columns on the rear side of the car floor. A car roof is connected to the top of the four columns, and the rear side wall of the car roof is connected to the backpack frame, thus providing an auxiliary connection between the car body and the backpack frame and improving the connection strength. In this structure, the backpack frame is connected to the horizontal support of the backpack frame by four independent columns, and the car roof is also connected to the top of the four columns, effectively ensuring structural strength. Furthermore, in this car structure, the left and right side panels and the back panel are easily disassembled and replaced. Only the positioning pressure plate needs to be removed to disassemble and replace the side panels or back panel inside the car.

[0009] In a further improvement, the positioning plate includes two abutment plates that are parallel to the two right-angled sides of the column, and a fixed base plate for connecting to the column is provided between the two abutment plates; a decorative cover plate is also snapped and connected between the two abutment plates and on the outside of the fixed base plate.

[0010] In a further improvement, the base has lower horizontal bars with mounting grooves on the upper part between the two columns on the left and right sides and the rear side. The lower ends of the left and right side plates and the back plate are respectively inserted into the mounting grooves of the corresponding lower horizontal bars. The top of the four columns has T-shaped slots. The top of the left and right side plates and the back plate are connected to horizontal pressure plates. The two ends of each horizontal pressure plate are engaged in the T-shaped slots of the corresponding columns through T-shaped connecting blocks.

[0011] In a further improvement, the car roof is provided with downward-facing positioning slots around its perimeter, and each of the four corners of the car roof is provided with a downward-extending first positioning insert plate. The tops of the four pillars are provided with first positioning holes. When the four first positioning insert plates are inserted into the first positioning holes on the tops of the four pillars, the tops of the left and right side plates and the back plate are respectively fitted into the four positioning slots of the car roof, and the upper end of the fixed base plate is provided with connecting screws for connecting to the first positioning insert plates.

[0012] In a further improvement, the mounting bracket includes two upright beams, the lower ends of which are connected to the base, and a horizontal fixing plate is connected between the tops of the two upright beams. The horizontal fixing plate is provided with multiple connecting screws for connecting to the car roof back panel.

[0013] In a further improvement, both of the upright beams are connected to mounting plates, and the rear sides of both mounting plates are provided with downwardly extending positioning grooves. The rear wall of the back plate is connected to a horizontally arranged positioning rod, and the two ends of the positioning rod are respectively engaged in the corresponding positioning grooves.

[0014] In a further improvement, the car roof includes a top frame and a decorative top plate. The decorative top plate is fitted onto the inner peripheral wall of the top frame. The top frame includes four corner connecting seats and four crossbeams. Each of the four corner connecting seats has a vertically distributed second positioning insert plate protruding from both sides. Each of the crossbeams has a second positioning hole at both ends for the second positioning insert plate to be inserted and fitted. The lower ends of the four crossbeams and the four corner connecting seats are all provided with a first receiving groove for forming the positioning slot.

[0015] In a further improvement, connecting screws for connecting to the second positioning insert plate of the corresponding corner connector are provided on the bottom wall of the receiving groove at both ends of the four crossbeams; second receiving grooves are provided on the inner wall of the four crossbeams and the inner wall of the corner of the four corner connectors, and the outer periphery of the decorative top plate is inserted into the corresponding second receiving groove.

[0016] In a further improvement, a third receiving groove is provided on the inner wall of each of the four crossbeams and the four corner connectors, and located below each of the second receiving grooves. Connecting screws for connecting to the second positioning plates of the corresponding corner connectors are provided on the bottom walls at both ends of the third receiving grooves of the four crossbeams. The multiple third receiving grooves form a mounting groove around the periphery, and a rubber strip light strip is embedded in the mounting groove.

[0030] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0031] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] See Figures 1-9As shown in the figure, this application discloses a backpack-type elevator car structure, which mainly includes a backpack frame 01 and a car assembly 02. The backpack frame 01 has an overall L-shaped structure and includes a mounting frame that is slidably connected to the guide rail and a base 1 that is horizontally connected to the lower front side of the mounting frame. Specifically, the mounting frame includes two vertical beams 16, which are connected together by multiple horizontal bars distributed vertically. The lower ends of the two vertical beams 16 are each connected to two L-shaped support arms. The vertical plates of the two L-shaped support arms are detachably connected to the lower ends of the two vertical beams 16 by connecting bolts. The base 1 is installed on the horizontal plate of the two L-shaped support arms. The L-shaped support arm here is cut from a single steel plate. There is no secondary welding or screw connection between its horizontal and vertical plates. The L-shaped connector is vertically arranged, meaning that the vertical and horizontal plates of the L-shaped connector are vertically connected to the lower ends of the upright beam 16 and the base 1, respectively. The integral L-shaped support arm, which is vertically connected, effectively increases the rigidity of the connection structure between the upright beam 16 and the base 1, ensuring the stability of the car during operation and improving user comfort.

[0034] Additionally, the car assembly 02 includes four uprights 2, left and right side panels 3, a back panel 4, and a car roof 5. The lower ends of the four uprights 2 are connected to the four corners of the base 1 via L-shaped connectors. In this embodiment, the four uprights 2 are all corner uprights 2, each with two right-angled sides. The lower ends of the two right-angled sides of each upright 2 are connected to two L-shaped connectors (not shown in the figure). Specifically, one connecting plate of the L-shaped connector is connected to the right-angled side of the upright 2 by screws, and the other connecting plate is connected to the side wall of the base 1 by screws.

[0035] Four rectangular columns 2 are connected at the four corners of the base 1. The left and right side panels 3 are respectively installed between the two front-to-back columns 2 on the left and right sides of the base 1. The back panel 4 is installed between the two left-to-right columns on the rear side of the base 1. The car roof 5 is detachably connected to the top of the four columns 2, so that the four columns 2, left and right side panels 3 and back panel 4 are assembled into an integrated car structure. The rear side wall of the car roof 5 is connected to the upper end of the backpack frame to further enhance the stability of the car structure and the backpack frame structure.

[0036] In the above structure, in addition to the lower end of the entire car structure being connected and fixed to the base 1 via the column 2, and the rear side of the car top 5 being reinforced to the upper end of the backpack frame, an auxiliary limiting structure is also provided between the outer wall of the back panel 4 and the backpack frame. Specifically, two horizontally arranged and vertically distributed positioning rods 20 are connected to the outer wall of the back panel 4, and two sets of positioning slot structures for mounting and positioning the two positioning rods 20 are provided on the backpack frame. That is, when the back panel 4 is installed between the two columns 2 on the rear side of the base 1, the two positioning rods 20 on its outer wall are respectively mounted and positioned in the corresponding positioning slots, preventing the back panel 4 from moving in the front-back direction, thus achieving the front-back positioning of the entire car.

[0037] In this embodiment, each of the four columns 2 has an inner wall with an inner opening on the inner wall of the two right-angled sides. Here, the inner side refers to the side facing the center of the car. The two ends of the left and right side plates 3 and the back plate 4 in the width direction are respectively fitted into the corresponding mounting grooves 6 of the column 2. Each column 2 has a positioning pressure plate that extends vertically and is used to press and position the corresponding side plate or back plate 4 in the width direction within the corresponding mounting groove 6.

[0038] Taking the left rear column 2 (denoted as left rear column 2) of base 1 as an example, the connection structure will be explained in detail: see appendix. Figure 9 The rear end of the left side panel is fitted into the left mounting groove 6 of the left rear pillar 2 from the inside out along the car body. The left end of the back panel 4 is fitted into the right mounting groove 6 of the left rear pillar 2 from the inside out along the car body. A vertically arranged positioning pressure plate is connected to the inner wall of the corner of the left rear pillar 2. The positioning pressure plate includes two abutment plates 7 and a fixed base plate 8. The two abutment plates 7 are parallel to the two right-angled sides of the left rear pillar 2, respectively. The fixed base plate 8 is connected to the inner wall of the corner of the left rear pillar 2 by connecting screws. The abutment plates 7 on both sides are pressed against the inner walls of the right end of the left side panel and the left end of the back panel 4, respectively, to achieve the connection and positioning of the left side panel, the back panel 4 and the left rear pillar 2. In addition, since the fixed base plate 8 is fitted with connecting screws in this structure, in order to improve the aesthetics and hide the fasteners, a rear decorative cover plate 9 is also fitted between the two abutment plates 7 of the positioning pressure plate and on the outside of the fixed base plate 8. Specifically, each of the two abutment plates 7 has a vertically extending locking seat on its sidewall, and the decorative cover plate 9 has two vertically extending locking buckles that engage with the two locking seats respectively on its rear sidewall. Of course, in other embodiments, the locking seats and locking buckles can also be non-integral, that is, multiple locking seats and locking buckles can be arranged vertically at intervals, as long as they can achieve stable locking between the decorative cover plate 9 and the positioning pressure plate.

[0039] Additionally, in this embodiment, see Appendix Figure 3 and 5A lower crossbar 10 with an insertion slot is provided between the two columns 2 on the left and right sides and the rear side of the base 1. The lower ends of the left and right side plates 3 and the back plate 4 are respectively inserted into the mounting slots 6 of the corresponding lower crossbar 10. Furthermore, a T-shaped slot 11 is provided on the top of each of the four columns 2. A horizontal pressure plate 12 is connected to the top of the left and right side plates 3 and the back plate 4. Both ends of each horizontal pressure plate 12 are engaged in the T-shaped slot 11 of the corresponding column 2 by T-shaped connecting blocks 13. In this structure, the T-shaped connecting blocks 13 and the T-shaped slots 11 on the column 2 are vertically engaged to achieve horizontal positioning, preventing the left and right side plates 3 and the back plate 4 from separating from the corresponding columns 2 in the horizontal direction after assembly, thus improving the stability of the car structure.

[0040] In the above structure, see Appendix Figure 3 The left and right side panels 3 each include a rectangular metal frame 32 and a wall panel 33. Preferably, the wall panel 33 is made of glass. Here, the glass wall panel 33 is wrapped with a metal frame 32 to protect it and prevent the glass wall panel from being bumped and chipped during installation, which would affect the aesthetics.

[0041] In this embodiment, the car roof 5 structure is installed as a whole from top to bottom above the four pillars 2, the left and right side panels 3, and the back panel 4. Specifically, the car roof 5 has downward-facing positioning slots around its perimeter, and each of the four corners of the car roof 5 has a downward-extending first positioning insert plate 14. The tops of the four pillars 2 each have a first positioning insertion hole 15. When the four first positioning insert plates 14 are inserted into the first positioning insertion holes 15 on the tops of the four pillars 2, the tops of the left and right side panels 3 and the back panel 4 are respectively fitted into the four positioning slots of the car roof 5. Connecting screws for connecting to the first positioning insert plates 14 are provided at the upper end of the fixed base plate 8 to strengthen the connection between the car roof 5 and the pillars 2. The connecting screws are also hidden behind the decorative cover plate 9 to avoid affecting the aesthetics of the car interior due to exposed fasteners. Preferably, the four pillars 2 are all made of aluminum profiles, so the mounting groove 6 and the first positioning insertion hole 15 structure are integrally formed on the pillar 2 substrate, simplifying the processing technology.

[0042] In the above structure, see Appendix Figure 2 A horizontal fixing plate 17 is also connected between the tops of the two upright beams 16. Multiple connection holes are provided on the horizontal fixing plate 17. After the car structure is assembled, the back plate 4 of the car roof 5 abuts against the horizontal fixing plate 17. Connection screws for connecting to the back plate 4 of the car roof 5 are connected in the multiple connection holes of the horizontal fixing plate 17, so as to realize the connection and fixation between the upper end of the car assembly 02 and the backpack frame 01.

[0043] For more details on the above structure, please refer to the appendix. Figure 2Two mounting plates 18 are connected to the two upright beams 16. Two positioning grooves 19 are provided on the rear side of the two mounting plates 18, which are distributed vertically and extend downwards to form two sets of positioning slots. The two ends of the two positioning rods 20 are respectively engaged in the corresponding positioning grooves 19.

[0044] On the other hand, see Appendix Figure 4 and 6 The car roof 5 structure in this embodiment includes a top frame and a decorative top plate 21. The decorative top plate 21 is fitted onto the inner peripheral wall of the top frame. The top frame includes four corner connecting seats 22 and four crossbeams 23. Each of the four corner connecting seats 22 has vertically distributed second positioning inserts 24 protruding outwards on both sides. Each crossbeam 23 has second positioning holes 25 at both ends for the insertion and mating of the second positioning inserts 24. The lower ends of the four crossbeams 23 and the four corner connecting seats 22 each have a first receiving groove 26 for forming an annular positioning slot. Specifically, for ease of molding and demolding, see the appendix. Figure 8 In this structure, the corner connector 22 includes a first seat 30 and a second seat 31. The second positioning plate 24 is integrally formed on both sides of the first seat 30. The second seat 31 is connected to the lower end of the corner inner wall of the first seat 30 by screws, and there is a gap between the second seat 31 and the first seat 30. This gap is the first receiving groove 26 on the corner connector 22. The upper end of the first positioning plate 14 is connected to the bottom of the first receiving groove 26 by screws, and the inner side wall of the second seat 31 is a concave arc surface to improve the aesthetics of the inner peripheral wall of the car roof 5.

[0045] In the above structure, see Appendix Figure 6 and 9 Each of the four crossbeams 23 has connecting screws on the bottom walls of the first receiving grooves 26 at both ends for connecting to the corresponding corner connecting seats 22. Second receiving grooves 27 are provided on the inner walls of the four crossbeams 23 and the inner walls of the corners of the four corner connecting seats 22. The outer periphery of the decorative top plate 21 is inserted into the corresponding second receiving groove 27. Preferably, the decorative top plate 21 is made of glass or transparent acrylic sheet, but other custom materials can also be used.

[0046] In this embodiment, a third receiving groove 28 is provided on the inner wall of the four crossbeams 23 and the four corner connecting seats 22, and below each second receiving groove 27. The bottom walls at both ends of the third receiving groove 28 of the four crossbeams 23 are provided with connecting screws for connecting to the second positioning insert plate 24 of the corresponding corner connecting seat 22. After the car roof 5 is assembled, the multiple third receiving grooves 28 form a mounting groove around the perimeter. The mounting groove is inlaid with a rubber strip light strip 29, which not only hides the connecting bolts, but also enhances the atmosphere inside the car.
