Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an installation mechanism for an integrated light curtain. Background Technology

[0002] Elevator door safety is a crucial aspect of ensuring passenger safety and preventing pinching accidents. In existing technologies, commonly used active safety protection devices for elevator doors mainly include light curtains and safety touch panels. Light curtains form a protective area by emitting and receiving infrared beams, achieving non-contact obstacle detection; safety touch panels trigger a switch signal upon slight contact with an obstacle, reopening the door. To improve reliability, integrated installation mechanisms that can simultaneously house light curtains and safety touch panels have emerged in existing technologies. However, because the longitudinal coverage of a light curtain is typically much larger than that of a safety touch panel, the installation mechanism designed for it is far longer than the actual requirements of the safety touch panel, resulting in significant waste of structural materials and increased production and installation costs.

[0003] To address the aforementioned issues, some manufacturers have proposed an improved installation structure, the core of which is modular installation achieved through the use of independent connecting brackets. One side of this bracket has a groove for sliding engagement with the light curtain housing, while the other side has a mounting slot for securing the safety touch panel. Through a sliding adjustment design, the length and position of the connecting bracket can be set as needed, effectively reducing its size and weight, and lowering production costs. However, this structure is only suitable for applications where both the light curtain and safety touch panel are present. If the user only uses the light curtain, a dedicated bracket still needs to be replaced, making it impossible to quickly switch between "pure light curtain" and "two-in-one" modes, thus reducing the convenience of use and maintenance. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an integrated light curtain installation mechanism that is simple in structure, easy to assemble, compatible with both "pure light curtain" and "light curtain + safety touch panel two-in-one" application modes, and realizes rapid switching between the two modes.

[0005] The technical solution adopted by this utility model to solve its technical problem is to provide an integrated light curtain installation mechanism, comprising:

[0006] The housing has an integrated light curtain body, and the housing has a first mounting part and at least one first fixing hole on the side opposite to the light curtain body. The first mounting part extends along the length direction of the housing, and the housing can be installed on the door through the first fixing hole.

[0007] The mounting bracket includes a connecting part and a second mounting part. The connecting part extends along the length of the mounting bracket and is detachably connected to the first mounting part. The second mounting part is used to mount a safety contact plate.

[0008] In the above-mentioned integrated light curtain installation mechanism, the connecting part and the first mounting part form a slidable snap-fit ​​engagement, the mounting bracket is provided with at least one locking hole that penetrates itself along the thickness direction, a locking structure is provided in the locking hole, the locking structure abuts against the first mounting part or is magnetically connected or threadedly connected, and the mounting bracket can be fixed to the housing through the locking structure.

[0009] In the above-mentioned integrated light curtain installation mechanism, when the locking structure forms an abutting connection with the first mounting part, the locking structure is a screw, the locking hole is a threaded hole, and when the locking structure is screwed in until its end abuts against the surface of the first mounting part, the connecting part and the first mounting part can be tightly fitted to restrict relative sliding between the connecting part and the first mounting part; when the locking structure forms a magnetic attraction connection with the first mounting part, the locking structure is a magnet, and the surface of the first mounting part is provided with a magnetic attraction layer; when the locking structure forms a threaded connection with the first mounting part, the locking structure is a screw, the first mounting part is provided with a plurality of spaced second fixing holes, and each of the second fixing holes is a threaded hole, and the locking structure forms a threaded connection with the first mounting part through the second fixing holes.

[0010] In the above-mentioned integrated light curtain installation mechanism, the connecting part is a wedge-shaped protrusion that protrudes towards the first mounting part, the first mounting part is a wedge-shaped groove that is recessed away from the connecting part, and there is a sliding gap between the side wall of the connecting part and the side wall of the first mounting part; when the locking structure abuts against the inner wall of the first mounting part, it can make the side wall of the connecting part fit against the side wall of the first mounting part.

[0011] In the above-mentioned integrated light curtain installation mechanism, the second mounting part is a groove that extends along the length direction of the mounting bracket, and the locking hole passes through the closed side of the second mounting part and the connecting part in sequence.

[0012] In the above-mentioned integrated light curtain installation mechanism, the housing is provided with an opening groove on the side away from the mounting bracket. The opening groove extends along the length of the housing and passes through both ends of the housing, and the opening of the opening groove faces the side away from the first mounting part. The light curtain body includes a mounting base, a light source structure and a light-transmitting plate. The mounting base is detachably disposed at the end of the housing. The light source structure is disposed on the mounting base and located in the opening groove. The light-transmitting plate is detachably sealed on the opening.

[0013] In the above-mentioned integrated light curtain installation mechanism, the mounting base is provided with a first positioning part, the first positioning part is provided with a first mounting hole that is detachably connected to the housing by fasteners, and the end of the housing is provided with a first positioning groove that forms a snap-fit ​​with the first positioning part.

Furthermore, a pressing portion is provided on both the mounting base and the sealing member. When the light-transmitting plate abuts against the support portion, and the mounting base and the sealing member are installed at the end of the housing, the pressing portion can fix the light-transmitting plate on the support portion.

[0016] In the above-mentioned integrated light curtain installation mechanism, the first positioning groove is connected to the second positioning groove and extends along the length of the housing.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] 1. In this utility model, by integrating a light curtain onto the housing and providing a first mounting part and a first fixing hole on the side of the housing away from the light curtain, and using an independent bracket detachably connected to the housing to install the safety touch panel, the functional integration and separation of the light curtain and the safety touch panel are achieved in terms of structure. This design allows the same housing to be used alone in a "pure light curtain" scenario, or to be quickly converted into a "light curtain and safety touch panel" combined application by adding a mounting bracket, truly achieving "one housing for multiple uses." This not only significantly improves the product's versatility and reduces the number of models, but also effectively reduces production, inventory, and maintenance costs. At the same time, it avoids the material waste problem caused by integrating the safety touch panel mounting part entirely onto a lengthy housing in traditional solutions.

[0019] 2. In this utility model, the connecting part of the mounting bracket and the first mounting part of the housing form a slidable snap-fit ​​engagement, and the position is locked by a locking structure, thereby allowing the mounting bracket to be flexibly adjusted and reliably fixed in the length direction of the housing. This design not only improves the assembly accuracy and efficiency of the mounting bracket, but also significantly enhances the installation flexibility and operational reliability.

[0020] 3. In this utility model, the light curtain body adopts a modular design, including a mounting base, a light-transmitting plate, and a light source structure. The housing has an opening slot that extends through both ends. The light source structure is mounted in the slot via a detachable mounting base, and the light-transmitting plate is fixed to the opening of the slot by means of the pressing parts on the mounting base and the sealing parts. This design facilitates the quick replacement and maintenance of the light source and the light-transmitting plate, effectively reducing maintenance costs. Attached Figure Description

[0033] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0034] like Figures 1 to 6 As shown, in this embodiment, an integrated light curtain mounting mechanism includes:

[0035] The housing 100 integrates a light curtain body 200, and the housing 100 is provided with a first mounting part 110 and at least one first fixing hole 120 on the side away from the light curtain body 200. The first mounting part 110 extends along the length direction of the housing 100, and the housing 100 can be installed on the door through the first fixing hole 120.

[0036] The mounting bracket 300 includes a connecting portion 310 and a second mounting portion 320. The connecting portion 310 extends along the length of the mounting bracket 300 and is detachably connected to the first mounting portion 110. The second mounting portion 320 is used to mount the safety touch panel. This design achieves functional integration and separation of the light curtain and the safety touch panel in terms of structure. This allows the same housing 100 to be used alone in a "pure light curtain" scenario, or to be quickly converted into a "light curtain and safety touch panel" combined application by adding the mounting bracket 300. This truly achieves "one housing for multiple uses," which not only significantly improves the product's versatility and reduces the number of models, but also effectively reduces production, inventory, and maintenance costs. At the same time, it avoids the material waste problem caused by integrating the safety touch panel mounting portion entirely onto the long housing 100 in traditional solutions.

[0037] Specifically, such as Figures 1 to 6 As shown, the installation mechanism mainly comprises two parts: a housing 100 and a mounting bracket 300. The housing 100 serves as the core load-bearing structure, integrating a light curtain body 200 on one side for non-contact obstacle detection; the other side has a first mounting portion 110 extending along its length, and at least one first fixing hole 120. This first fixing hole 120 is used to fix the housing 100 to the elevator door panel, ensuring the stability and reliability of the installation mechanism. The first mounting portion 110 serves as a functional expansion interface, connecting to the mounting bracket 300 and providing a connection base for the subsequent installation of the safety contact plate.

[0038] Furthermore, the housing 100 has a strip-shaped structure, and its length can be adapted to the actual size of the door. This design not only ensures the effective coverage of the light curtain, but also allows the housing 100 to flexibly adapt to elevator door panels of different sizes.

[0039] Furthermore, a first fixing hole 120 is provided on the side wall of the housing 100, located between the first mounting part 110 and the light curtain body 200, and the first fixing hole 120 penetrates the housing 100 along the thickness direction of the housing 100, with its axis extending perpendicular to the length direction of the housing 100. This arrangement ensures the stable installation of the housing 100 on the door panel, while facilitating its use in conjunction with the mounting bracket 300.

[0040] Preferably, multiple first fixing holes 120 are provided and arranged at intervals along the length of the housing 100. This design of multiple fixing holes increases installation flexibility, allowing users to select appropriate fixing points according to the actual installation environment, thereby improving installation accuracy and stability. In addition, multi-point fixing can effectively distribute stress and avoid deformation or damage due to excessive force at a single point.

[0041] Furthermore, the connection between the first mounting part 110 and the mounting bracket 300 is detachable, such as by sliding snap-fit, fastener connection, or snap-fit ​​connection, to achieve convenient assembly and quick disassembly. This design not only facilitates installation, debugging, and subsequent maintenance, but also significantly improves the versatility and adaptability of the mounting mechanism in different application scenarios.

[0042] Preferably, the first mounting portion 110 and the connecting portion 310 form a slidable snap-fit ​​engagement, allowing the mounting bracket 300 to slide freely along its length and be positioned. This design allows the user to flexibly adjust the position of the mounting bracket 300 on the housing 100 according to the arrangement requirements of the mounting contact plate, achieving precise positioning. After adjustment to the target position, the mounting bracket 300 can be fixed to the housing 100 through engagement with the locking structure 331, preventing the bracket from loosening or shifting due to vibration or external forces during elevator operation, thereby effectively improving installation flexibility, positioning accuracy, and long-term operational reliability.

[0043] Furthermore, the first mounting portion 110 and the connecting portion 310 form a concave-convex fit structure to achieve smooth guidance and stable sliding engagement. Preferably, the concave-convex fit is a wedge-shaped structure, with the two parts interlocking and sliding along their length. This design not only facilitates assembly guidance and reduces installation difficulty and machining accuracy requirements, but also utilizes the wedge-tightening effect between the inclined surfaces when the locking structure 331 applies pre-tightening force, gradually bringing the sidewalls of the connecting portion 310 and the first mounting portion 110 into contact and pressing together, thereby effectively eliminating the initial fit gap and significantly improving connection rigidity, positioning accuracy, and long-term operational stability.

[0044] Preferably, the first mounting portion 110 is a wedge-shaped groove recessed away from the connection direction, and there is a sliding gap 400 between the side wall of the first mounting portion 110 and the side wall of the connecting portion 310 to ensure that the mounting bracket 300 can slide smoothly and achieve position adjustment. When the locking structure 331 abuts against the bottom wall of the first mounting portion 110, the side wall of the connecting portion 310 of the mounting bracket 300 gradually presses against the side wall of the groove, realizing the transformation from "sliding fit" to "tight connection", preventing loosening or abnormal noise caused by vibration or impact during use.

[0045] Furthermore, the first mounting part 110 and the locking structure 331 can be connected in various ways, including abutment, magnetic connection or threaded connection, to meet the usage requirements under different working conditions.

[0046] To integrate the light curtain body 200, the housing 100 has a U-shaped opening slot 130 on the side opposite to the mounting bracket 300. This opening slot 130 extends along the length of the housing 100 and passes through both ends of the housing 100, with its opening facing away from the first mounting portion 110, forming an internal accommodating space for the light curtain body 200. This design not only facilitates the assembly and maintenance of components such as the mounting base 210, the light source structure 220, and the light-transmitting plate 230, but also provides an unobstructed optical channel for the infrared beam emission and reception of the light source structure 220. Simultaneously, the through-type structure facilitates the extrusion molding process of the housing 100, improving production efficiency and dimensional consistency, making it suitable for mass production.

[0047] Furthermore, each end of the opening slot 130 is provided with a support portion 131. This support portion 131 provides horizontal support to the end of the light-transmitting plate 230 to prevent sagging, deformation, or stress concentration during installation or use. The support portion 131 can extend horizontally from one side of the inner wall of the opening slot 130 to the opposite side and connect vertically thereto, forming a continuous support platform; alternatively, it can extend horizontally from both sides of the inner wall of the opening slot 130 towards the middle, forming a cantilevered support structure with a certain gap between them. This design ensures effective axial and radial support for the light-transmitting plate 230 and facilitates the insertion and positioning of the light-transmitting plate 230 during assembly. Simultaneously, when a double-sided extension structure with a gap is used, it can accommodate the thermal expansion and contraction of the light-transmitting plate 230 due to temperature changes, avoiding excessive internal stress and improving structural durability and optical stability.

[0048] Preferably, when the support portion 131 extends horizontally from the inner walls of both sides of the opening groove 130 towards the center to form a cantilever support structure with opposite sides, its free end extends vertically upward to cooperate with the side wall of the opening groove 130 to form a groove; at the same time, the light-transmitting plate 230 is correspondingly provided with a protrusion that fits into the groove. This design further increases the contact area between the support portion 131 and the light-transmitting plate 230, making the connection between the two more reliable.

[0049] Furthermore, the housing 100 has a first positioning groove 140 at one end near the mounting base 210. This first positioning groove 140 engages with a first positioning part 211 on the mounting base 210, and the shape and size of the first positioning groove 140 are adapted to the first positioning part 211. During assembly, this engagement allows for pre-positioning of the mounting base 210 in the axial and radial directions, effectively guiding the mounting base 210 into accurate position and avoiding misalignment, tilting, or rotational deviations, thereby significantly improving assembly accuracy and efficiency. This design is particularly beneficial for the precise positioning of the light source structure 220, ensuring the alignment of the light curtain's emitting and receiving light paths and improving detection reliability.

[0050] Furthermore, the housing 100 has a second positioning groove 150 at one end near the sealing member 500. This second positioning groove 150 engages with the second positioning part 510 on the sealing member 500, and the shape and size of the second positioning groove 150 are adapted to the second positioning part 510. Through this engagement, the sealing member 500 can be quickly positioned during installation and reliably connected to the end of the housing 100. This design not only enhances the structural integrity of the end of the housing 100 but also effectively improves the sealing performance, preventing external dust, moisture, or debris from entering the opening groove 130, avoiding contamination or damage to the light source components, circuit connections, and light-transmitting plate 230, and ensuring the long-term stable operation of the light curtain.

[0051] Preferably, the first positioning groove 140 and the second positioning groove 150 are connected and extend through the length of the housing 100. This design not only simplifies the internal contour design of the housing 100, which is beneficial for the continuous extrusion molding process of aluminum profiles or engineering plastic housings 100, and reduces mold complexity and manufacturing costs, but also ensures the dimensional consistency of the positioning structures at both ends, thereby improving the stability and processing efficiency of mass production.

[0052] In this embodiment, the light curtain body 200 includes a mounting base 210, a light source structure 220, and a light-transmitting plate 230. The mounting base 210 is detachably mounted on one end of the housing 100. The light source structure 220 is mounted on the mounting base 210 and located within the opening slot 130 of the housing 100, used to emit or receive infrared beams for obstacle detection. The light-transmitting plate 230 is detachably sealed at the opening of the opening slot 130, allowing the beam to pass through smoothly while providing physical protection for the internal components. This modular design decomposes the light curtain body 200 into multiple independent and replaceable functional units, facilitating step-by-step installation and alignment during assembly and significantly improving the convenience of later maintenance. When the light source structure 220 or the light-transmitting plate 230 is damaged, contaminated, or requires upgrading, there is no need to replace the entire housing 100 or the light curtain assembly; only the corresponding parts need to be disassembled for repair or replacement, effectively reducing maintenance costs and improving equipment availability.

[0053] Furthermore, the mounting base 210 is provided with a first positioning part 211 protruding towards the sealing member 500. This first positioning part 211 has a first mounting hole 212 for fixing the mounting base 210 to the end of the housing 100 using fasteners. The axis of the first mounting hole 212 is perpendicular to the length direction of the housing 100 and parallel to the bottom wall of the opening groove 130. A first through hole 160, aligned with and communicating with the first mounting hole 212, is provided on the outer wall of the housing 100 at a corresponding position. Fasteners (such as screws) can pass through the first through hole 160 and the first mounting hole 212 in sequence, achieving a reliable connection between the mounting base 210 and the housing 100. This detachable connection method facilitates the replacement, adjustment, and maintenance of the light source structure 220.

[0054] Furthermore, the light-transmitting plate 230 is horizontally positioned at the opening of the slot 130 and extends along the length of the housing 100, forming a complete seal over the entire opening area. The two ends of the light-transmitting plate 230 abut against the support portions 131 at both ends of the housing 100, with the support portions 131 providing axial support to prevent it from sagging or breaking due to its own weight or external forces.

[0055] To limit the position of the light-transmitting plate 230, both the mounting base 210 and the sealing member 500 are provided with pressing parts 520. The two pressing parts 520 are located near the ends of the mounting base 210 and the sealing member 500 close to the light-transmitting plate 230, extending horizontally towards the light-transmitting plate 230 to cover the surface of the light-transmitting plate 230 facing away from the housing 100. When the light-transmitting plate 230 abuts against the support part 131, and the mounting base 210 and the sealing member 500 are installed at the end of the housing 100, the pressing parts 520 together apply a clamping force to the light-transmitting plate 230, firmly clamping it between the support part 131 and the pressing parts 520. This design not only ensures that the light-transmitting plate 230 is firmly installed and not easily loosened, but also effectively disperses local stress, avoiding the risk of breakage due to point contact or unilateral force, significantly improving the installation reliability and long-term stability of the light-transmitting plate 230.

[0056] Furthermore, a sealing member 500 is detachably provided at one end of the housing 100 away from the mounting base 210 to seal the other end of the opening slot 130, preventing dust, moisture, or foreign objects from entering the interior of the housing 100 and ensuring the cleanliness and operational stability of the light curtain body 200. The sealing member 500 has a second positioning part 510 protruding towards the mounting base 210, and a second mounting hole 511 is provided on this second positioning part 510. It is detachably connected to the housing 100 by fasteners (such as screws). The housing 100 also has a second through hole 170 at a corresponding position, aligned with and communicating with the second mounting hole 511. Fasteners pass through the second through hole 170 and the second mounting hole 511 in sequence, firmly fixing the sealing member 500 to the end of the housing 100. This design not only ensures the sealing integrity at both ends of the housing 100, but also facilitates the quick disassembly and assembly of the sealing component 500 when maintaining or replacing the light-transmitting plate 230 and the light source structure 220, thereby improving maintenance efficiency and further enhancing the modularity and flexibility of the entire light curtain body 200.

[0057] In this embodiment, the mounting bracket 300 is an independent module, including a connecting part 310 and a second mounting part 320. The connecting part 310 extends along the length of the bracket and forms a detachable connection with the first mounting part 110 on the housing 100, thereby enabling quick assembly and convenient separation between the mounting bracket 300 and the housing 100. This design allows the mounting bracket 300 to be flexibly selected according to actual application requirements, suitable for scenarios with either a "pure light curtain" or a "light curtain + safety touch panel" dual configuration.

[0058] Preferably, the connecting portion 310 and the first mounting portion 110 form a slidable snap-fit ​​engagement, and the two constitute a concave-convex fit structure. Specifically, the connecting portion 310 is a wedge-shaped protrusion that protrudes towards the first mounting portion 110 and forms a sliding gap 400 between it and the first mounting portion 110 to ensure smooth adjustment. When the locking structure 331 abuts against the inner wall of the first mounting portion 110, the connecting portion 310 can be displaced away from the first mounting portion 110 until its sidewall is tightly fitted with the inner sidewall of the first mounting portion 110, thereby eliminating the initial sliding gap 400. This process achieves a smooth transition from a "slidable state" to a "securely locked state," effectively preventing the mounting bracket 300 from loosening, displacing, or making abnormal noises due to vibration or impact during elevator operation, significantly improving the reliability and long-term stability of the connection.

[0059] To ensure reliable fixation of the mounting bracket 300, the mounting bracket 300 is provided with at least one locking hole 330 extending through itself along the thickness direction. A locking structure 331 is installed inside the locking hole 330. The locking structure 331 abuts against, magnetically connects to, or is threadedly connected to the first mounting part 110, thereby firmly fixing the mounting bracket 300 to the housing 100 and preventing it from loosening or shifting during elevator operation.

[0060] Furthermore, when the locking structure 331 forms an abutting connection with the first mounting portion 110, the locking structure 331 is a screw, the locking hole 330 is a threaded hole, and when the locking structure 331 is screwed in until its end abuts against the surface of the first mounting portion 110, it can apply a reverse force to the connecting portion 310, thereby causing the inclined sidewall of the connecting portion 310 to fit tightly against the inclined sidewall of the first mounting portion 110, thus restricting relative sliding between the connecting portion 310 and the first mounting portion 110 and achieving stable locking. This design achieves locking while ensuring the structural strength of the housing 100.

[0061] Furthermore, when the locking structure 331 is magnetically connected to the first mounting part 110, the locking structure 331 is a magnet, and the surface of the first mounting part 110 is provided with a magnetic layer, so as to achieve quick positioning and auxiliary fixation through magnetic force. This method is suitable for maintenance scenarios that require frequent disassembly and assembly, and has the advantages of convenient operation and no mechanical wear.

[0062] Furthermore, when the locking structure 331 is threadedly connected to the first mounting portion 110, the locking structure 331 is a screw, and the first mounting portion 110 has a plurality of spaced second fixing holes (not shown in the figure), and each second fixing hole is a threaded hole. The locking structure 331 forms a threaded connection with the first mounting portion 110 through the second fixing holes. This connection method has high connection strength and vibration resistance, and is suitable for application scenarios with high stability requirements.

[0063] Preferably, multiple locking holes 330 are provided, spaced apart along the length of the mounting bracket 300, to improve the uniformity of the fixing point distribution and the overall connection rigidity. Each locking hole 330 sequentially passes through the closed side of the second mounting part 320 and the connecting part 310. This design facilitates the insertion and operation of the locking structure 331, improving assembly efficiency and convenience; it also ensures that the locking force is effectively transmitted to the mating area between the connecting part 310 and the first mounting part 110, enhancing the structural stability and deformation resistance of the mounting bracket 300 under complex working conditions.

[0064] Furthermore, a second mounting part 320 is located on the side of the mounting bracket 300 opposite to the connecting part 310, and is used to install a safety contact plate. When the elevator door makes slight contact with an obstacle during the closing process, the safety contact plate is pressed and generates a mechanical trigger signal. This signal can be transmitted to the elevator control system, which will then execute a reverse operation command to immediately stop the door from closing and reopen it, thereby achieving a reliable contact-type safety protection function.

[0065] Furthermore, the second mounting portion 320 is a groove extending along the length of the mounting bracket 300, with its opening facing away from the connecting portion 310, for forming a detachable snap-fit ​​with the safety contact plate. This design not only facilitates the quick installation and removal of the safety contact plate but also ensures that it maintains a stable connection and accurate position during operation.

[0066] Preferably, the inner wall of the second mounting part 320 is provided with a limiting rib 321 to enhance assembly guidance and anti-detachment performance, thereby further improving installation efficiency and reliability.
