Description

Technical Field

[0001] This utility model relates to the technical field of garage safety devices, specifically to a safety barrier bar. Background Technology

[0002] A multi-level parking garage is a facility that utilizes space resources to increase parking capacity by parking vehicles in multiple levels, effectively alleviating urban parking difficulties. Its installation includes a steel frame structure for a stable main support; lifting and transmission devices, such as motors, chains, and steel cables, responsible for the vertical lifting of vehicles; lateral movement devices for the horizontal movement of vehicles between different parking spaces; and a control system that uses programming and sensors to precisely control the operation of each device, ensuring the safe and accurate parking and retrieval of vehicles. These devices work together to guarantee the efficient operation of the multi-level parking garage.

[0003] However, most multi-level parking garage projects rely solely on parking platform barriers to restrict vehicle movement. If the driver misoperates or drives too fast, there is a risk that the vehicle will run over the parking platform barriers and fall into the aisle or shaft, causing a safety accident. Utility Model Content

[0004] This utility model proposes a safety barrier bar, which solves the problem in related technologies that rely solely on parking platform barriers to restrict vehicle movement. If the driver misoperates or the speed is too fast, there is a risk that the vehicle will run over the parking platform barrier and fall into the tunnel or shaft.

[0007] The column is a plurality of columns, which are symmetrically arranged on the walls on both sides of the garage entrance and exit;

[0008] A lifting drive component is mounted on the column;

[0009] A safety bar is mounted on the lifting drive component. After the safety bar is lowered, it is used to block vehicles. The safety bar has an anti-collision surface.

[0010] Optionally, the lifting drive includes:

[0011] A rotating shaft is rotatably disposed between two adjacent columns, and the rotating shaft is located at the top of the column;

[0014] A chain is wound around the first sprocket and the second sprocket, and the safety bar is disposed on the chain;

[0015] A driver is mounted on the column and is connected to the rotating shaft. The driver is used to drive the safety bar on the chain to move back and forth.

[0016] Optional, also includes:

[0017] The safety bar has several limiting plates, which are respectively disposed at both ends of the column. The distance between two adjacent limiting plates is the moving distance of the safety bar.

[0018] Optionally, the column has a U-shaped cross-section, and the first sprocket, the second sprocket, and the chain are all located inside the column.

[0019] Optional, also includes:

[0020] An anti-pinch photoelectric device is installed at the bottom of the column, and the anti-pinch photoelectric device is used to sense whether a vehicle is passing by.

[0021] Optional, also includes:

[0022] The mounting plates are of several kinds, and the mounting plates are respectively disposed on the top surface and side wall of the column. The column is installed on the garage entrance and exit through the mounting plates.

[0023] Optional, also includes:

[0024] A guide wheel assembly, comprising several guide wheels, is disposed on the inner side of the column and located near the limiting plate;

Detailed Implementation

[0041] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0042] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0043] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Reference Figures 1-5 As an embodiment of this utility model, a safety vehicle blocking bar is proposed, which is installed at the entrance and exit 1 of a garage. It includes several columns 2, which are symmetrically arranged on the walls on both sides of the entrance and exit 1 of the garage. A lifting drive 3 is arranged on the columns 2. A safety bar 6 is arranged on the lifting drive 3. After the safety bar 6 moves down, it is used to block vehicles. The safety bar 6 has an anti-collision surface 501.

[0046] In the above design, column 2 possesses sufficient strength and stability. The height of column 2 is determined based on the actual conditions of garage entrance / exit 1, and it is installed on both sides of the garage entrance / exit 1, securely fixed to the wall by welding or expansion bolts. The safety bar 6 is primarily a rectangular hollow steel tube structure made of high-strength alloy steel, capable of withstanding significant impact forces. Its length is slightly less than the width of garage entrance / exit 1 to ensure effective vehicle blocking. The anti-collision surface 501 is made of a rubber and metal composite material, effectively buffering the impact force during vehicle collisions and preventing vehicle scratches.

[0047] When a vehicle enters or exits the garage normally, the lifting drive unit 3 raises the safety bar 6, allowing the vehicle to pass smoothly. After the vehicle stops, the lifting drive unit 3 activates, causing the safety bar 6 to quickly descend, aligning the anti-collision surface 501 with the direction of vehicle travel, preventing the vehicle from accidentally moving forward at high speed and crashing into the aisle or shaft. This effectively fills the safety gap in conventional garages regarding vehicle obstruction, significantly reducing the risk of vehicles falling due to misoperation or speeding over the parking platform barrier, thus ensuring the safety of the vehicle and the driver.

[0048] Furthermore, the lifting drive component 3 includes: a rotating shaft 4 rotatably disposed between two adjacent columns 2, with the rotating shaft 4 located at the top of the column 2; a first sprocket 301 disposed on the rotating shaft 4; a second sprocket 302 disposed at the bottom of the column 2; a chain 3033 wound around the first sprocket 301 and the second sprocket 302; a safety bar 6 disposed on the chain 3033; and a driver 304 disposed on the column 2, the driver 304 being connected to the rotating shaft 4 in a transmission manner, and the driver 304 being used to drive the safety bar 6 on the chain 3033 to reciprocate.

[0049] In the above scheme, when the safety bar 6 needs to be lowered, the driver 304 receives a control signal and starts according to a preset program. The motor rotates clockwise, driving the shaft 4 to rotate, and the first sprocket 301 rotates accordingly. Through the chain 3033, the safety bar 6 slowly descends along the column 2. When the safety bar 6 needs to be raised, the motor reverses, driving the shaft 4 to rotate counterclockwise, and the safety bar 6 rises along the column 2 back to its initial position. The raising and lowering of the safety bar 6 is achieved according to control commands, and it has high transmission efficiency and low energy consumption, extending the service life of the device and reducing maintenance costs.

[0050] Furthermore, it also includes limiting plates 9, of which there are several, and the several limiting plates 9 are respectively set at both ends of the column 2, and the distance between two adjacent limiting plates 9 is the moving distance of the safety bar 6.

[0051] In the above scheme, during the lifting and lowering process, when the safety bar 6 rises to the top or descends to the bottom, it will contact the limiting plate 9. At this time, due to the blocking effect of the limiting plate 9, the movement of the safety bar 6 will immediately stop, preventing it from exceeding the predetermined lifting and lowering range and avoiding damage to the device or affecting its normal operation due to excessive lifting and lowering. This effectively limits the movement range of the safety bar 6, avoids excessive displacement of the safety bar 6 due to mechanical failure or misoperation, ensures the stability and safety of the device, reduces the possibility of equipment damage, and improves the reliability of the entire system.

[0052] Furthermore, the cross-section of the column 2 is U-shaped, and the first sprocket 301, the second sprocket 302, and the chain 3033 are all located inside the column 2.

[0053] In the above scheme, multiple reinforcing ribs are reasonably distributed inside and outside the U-shaped structure to enhance the load-bearing capacity and deformation resistance of the column 2. The first sprocket 301, the second sprocket 302, and the chain 3033 are all installed in predetermined positions inside the column 2 and fixed by specially arranged brackets and slots to ensure that the transmission components remain stable during operation and do not shift or shake.

[0054] During the raising and lowering of the safety bar 6, the chain 3033 runs smoothly on the sprocket inside the column 2. The U-shaped column 2 not only protects the transmission components, preventing dust and debris from affecting transmission efficiency, but also makes the entire device more aesthetically pleasing and reduces external interference to the transmission system. The U-shaped column 2 not only meets the installation and protection requirements of the transmission components, but also improves the structural strength of the column 2, while improving the overall appearance and environmental adaptability of the device, reducing maintenance difficulty, and extending the service life of the device.

[0055] Furthermore, it also includes an anti-pinch photoelectric device 8, which is installed at the bottom of the column 2. The anti-pinch photoelectric device 8 is used to sense whether a vehicle is passing by.

[0056] In the above scheme, the anti-pinch photoelectric device 8 uses an infrared sensor as the core detection element, with the transmitter and receiver installed on both sides of the bottom of the column 2, respectively. The sensor housing is made of waterproof, dustproof, and corrosion-resistant engineering plastic, ensuring stable operation in harsh environments such as humid and dusty garages, and accurately detecting whether a vehicle is passing by.

[0057] Operating Process: When a vehicle approaches garage entrance / exit 1, the anti-pinch photoelectric device 8 continuously emits and receives infrared signals to monitor the vehicle's position in real time. If the vehicle is detected in a dangerous area during the descent of the safety bar 6, the sensor immediately transmits the signal to the control system. The control system responds rapidly within seconds, controlling the lifting drive 3 to stop descent or raising the safety bar 6, effectively preventing the vehicle from being pinched. This greatly improves the safety of the device, effectively preventing accidents such as pinching injuries to the vehicle during the operation of the safety bar 6, ensuring the safe passage of vehicles, reducing potential damage to vehicles caused by equipment operation, and enhancing the user experience.

[0058] Furthermore, it also includes mounting plates 7, of which there are several, and the mounting plates 7 are respectively set on the top surface and side wall of the column 2, and the column 2 is installed on the garage entrance / exit 1 through the mounting plates 7.

[0059] In the above scheme, when installing the safety barrier, the mounting plate 7 and the column 2 are first assembled and connected, ensuring a tight and secure connection. The column 2 is then fixed to the wall of the garage entrance / exit 1 using bolts, ensuring that the column 2 will not shift or shake when subjected to external forces such as vehicle collisions. Ensuring the stable installation of the safety barrier at the garage entrance / exit 1 enhances the stability of the device under vehicle impact conditions, effectively preventing safety accidents caused by insecure installation, and guaranteeing the normal operation of the device and the effective functioning of its safety protection features.

[0060] Furthermore, it also includes a guide wheel assembly 11, which has several units. The guide wheel assembly 11 is located inside the column 2 and near the limiting plate 9. The abutment plate 10 is located on the safety bar 6 and abuts against the guide wheel assembly 11.

[0061] In the above scheme, when the safety bar 6 rises or falls under the action of the lifting drive component 3, the abutment plate 10 is in close contact with the rollers of the guide wheel assembly 11. As the safety bar 6 moves, the rollers rotate under the push of the abutment plate 10, and the guide wheel assembly 11 provides stable guidance and support for the safety bar 6, making the lifting process of the safety bar 6 within the column 2 more stable and smooth, and reducing swaying and deviation.

[0062] This effectively improves the stability and accuracy of the lifting of the safety bar 6, reduces friction and wear between the safety bar 6 and the column 2, extends the service life of the device, and also reduces potential safety hazards caused by unstable lifting of the safety bar 6, ensuring the reliable operation of the device.

[0063] Furthermore, the safety bar 6 includes a bar body 601; a baffle 602 is disposed on one side of the bar body 601; one end of a spring 603 abuts against the side wall of the bar body, and the other end abuts against the baffle 602, and the spring 603 is used to provide force to support the baffle 602.

[0064] In the above scheme, one end of the spring 603 is fixed to the mounting bracket on the side wall of the bumper 601 by welding or a snap ring, and the other end is tightly abutted against the connecting block on the back of the baffle 602, providing stable support for the baffle 602. Under normal circumstances, the spring 603 is in its natural extended state, supporting the baffle 602 in a predetermined position. When the vehicle collides with the safety bumper 6, the baffle 602 is subjected to impact force and moves towards the side of the bumper 601, compressing the spring 603. During the compression process, the spring 603 absorbs part of the collision energy, playing a buffering role, effectively reducing the impact force on the vehicle and the safety bumper 6, protecting the vehicle from serious damage, and reducing the deformation and damage to the safety bumper 6 caused by the collision. After the collision force disappears, the elastic restoring force of the spring 603 returns the baffle 602 to its initial position, ready for the next operation.

[0065] The inclusion of spring 603 significantly improves the buffering performance of the safety bar 6, reduces the impact force during vehicle collisions, protects the structural integrity of the vehicle and the safety bar 6, reduces maintenance and replacement costs, and also improves the safety and reliability of the device, extending its service life.

[0066] Furthermore, it also includes rubber blocks 5, which are arranged in several pieces. The rubber blocks 5 are spaced apart on the surface of the baffle 602 away from the bar body 601, and the rubber blocks 5 form an anti-collision surface 501.

[0067] In the above scheme, when the vehicle collides with the safety bar 6, it first comes into contact with the anti-collision surface 501 formed by the rubber block 5. The rubber block 5 uses its own elastic deformation to further buffer the impact force of the vehicle, while the friction of its surface makes it easier for the vehicle to stop upon collision, effectively preventing the vehicle from continuing to move forward and better protecting the vehicle and the safety bar 6. The anti-collision surface 501 formed by the rubber block 5 enhances the buffering and anti-slip capabilities of the safety bar 6, further reducing the risk of damage during vehicle collisions, improving the safety protection performance of the device, reducing the possibility of vehicle displacement and loss of control due to collisions, and ensuring the safe operation of the garage.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
