Description

Technical Field

[0001] This utility model relates to the field of parking lock technology, and in particular to a safe parking lock and its anti-collision mechanism. Background Technology

[0002] The core protective function of parking space locks relies on a retractable barrier arm structure. When a vehicle leaves, the barrier arm rises to form a physical barrier, preventing unauthorized vehicles from occupying the parking space; when a vehicle enters, the barrier arm lowers to unlock, allowing for unimpeded passage. The impact resistance of the parking space lock directly determines its lifespan and reliability.

[0003] Existing parking locks lack sufficient anti-collision performance. When the raised arm is accidentally hit by a vehicle, kicked, or maliciously pried, the impact force is directly transmitted to the pivot and related transmission components, easily causing the arm to bend, the pivot to deform, or the transmission gears to break, leading to malfunctions such as the arm jamming or inability to raise or lower. Although some improved parking locks have added buffer springs, these can only mitigate minor impacts, and the springs are prone to fatigue and failure under long-term stress, making them unable to withstand high-intensity impacts.

[0004] In view of the above-mentioned technical problems, this utility model proposes a new technical solution, which improves the anti-collision performance by optimizing the limiting structure of the stop arm, avoids damage to the transmission components due to violent impact, and ensures that the stop arm can maintain structural stability in both the raised and lowered unlocked states, thereby extending the service life of the parking lock and improving protection security. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a safe parking space lock and its anti-collision mechanism, which aims to solve the technical problem that the anti-collision performance of parking space locks in the prior art needs to be improved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A parking space lock anti-collision mechanism includes a base plate and two opposing stop arms. The base plate is provided with a support and a stop block corresponding to each stop arm. Each stop arm is rotatably connected to the support on the same side. Each stop arm has a first abutment part at its bottom end and each stop block has a second abutment part. Each first abutment part can abut against the second abutment part on the same side.

[0007] Furthermore, in the aforementioned parking space lock anti-collision mechanism, a pivot is provided between the two supports, and each stop arm is connected to the pivot.

[0008] Furthermore, in the parking space lock anti-collision mechanism, each first abutting part has a first abutting plane, and each second abutting part has a second abutting plane that is adapted to the corresponding first abutting plane.

[0009] Furthermore, in the aforementioned parking space lock anti-collision mechanism, when each stop arm rotates upward to the locked state, the first contact surface faces forward; when each stop arm rotates downward to the unlocked state, the stop arm faces forward.

[0010] Furthermore, in the aforementioned parking space lock anti-collision mechanism, each support includes two lugs, and the bottom end of each stop arm is located between the two lugs on the same side; the second abutment part is located between the two lugs on the same side.

[0011] Furthermore, in the aforementioned parking space lock anti-collision mechanism, each stop block is fixedly connected to the two lugs on the same side.

[0012] Furthermore, in the aforementioned parking space lock anti-collision mechanism, a clearance groove is provided on the base plate at the bottom end of each stop arm.

[0013] This utility model also provides a safe parking space lock, which includes a drive device and, unlike the prior art, also includes the parking space lock anti-collision mechanism described above. The drive device is used to drive the two stop arms to rotate.

[0014] Beneficial Effects: This utility model provides a safe parking lock and its anti-collision mechanism. Compared with the prior art, by setting supports and blocks at each stop arm on the base plate, and providing a first abutment part at the bottom of the stop arm and a second abutment part on the block, when the stop arm is impacted, the first abutment part and the second abutment part abut against each other, effectively transferring the impact force to the base plate. This significantly enhances the anti-collision capability of the mechanism, better resists vehicle impacts, and extends the service life of the parking lock. Furthermore, when the stop arm is impacted, the second abutment part restricts further rotation of the stop arm, thus ensuring that the transmission mechanism with the stop arm is not damaged.

Detailed Implementation

[0027] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0028] Please see Figures 1 to 11 This utility model provides a safe parking space lock and its anti-collision mechanism. The accompanying drawings are for illustrative purposes only and are not proportional to the actual product. The drawings only depict structures relevant to the innovation of this application; some conventional structures are not specifically shown. The terms "first," "second," etc., used herein are merely different names for similar structures for ease of explanation and are not intended to limit this application. For ease of explanation, some directional terms are unavoidably used herein, but these directional terms are not intended to limit this application. The "bottom end" of the stop arm mentioned herein is described based on the state after the stop arm is raised. Figure 3 From this perspective, the left side is the front side.

[0029] Please refer to the following first. Figures 1 to 7 The parking space lock anti-collision mechanism includes a base plate 1 and two opposing stop arms 2. A support 3 and a stop block 4 are respectively provided on the base plate at each stop arm. Each stop arm 2 is rotatably connected to the support 3 on the same side. Each stop arm 2 has a first abutment portion 21 at its bottom end, and each stop block 4 has a second abutment portion 41. The first abutment portion of each stop arm can abut against the second abutment portion on the same side. Specifically, the stop arm 2 rotates upwards (…). Figure 3 The limit that can be reached (with the viewpoint being clockwise rotation) is that the first abutment part 21 and the second abutment part 41 are completely in contact. At this point, due to the rigid limit of the second abutment part 41, the stop arm 2 cannot rotate any further.

[0030] The thickness of the first and second abutment portions is preferably 8-12mm. The stop arm 2 can be made of 45# steel or high-strength aluminum alloy. The base plate can be integrally stamped from Q235 carbon structural steel, and its thickness is preferably 8-12mm. Of course, if a greater load-bearing capacity is considered, higher strength steel can be used to support the base plate. Preferably, the hardness of the stop block 4 is ≥HB200; the support is preferably made of 45# steel. The stop block and support are fixedly connected to the base plate to ensure sufficient strength to withstand violent impacts from the outside. Preferably, the stop block and support are welded to the base plate, and stress-relief annealing treatment is required after welding to eliminate residual welding stress, so as to ensure that the parking space lock anti-collision mechanism can withstand a large impact force.

[0031] It should be noted that although the shape of the stop 4 in the attached drawing is irregular, in actual applications, the stop does not have to be an irregular part.

[0032] Preferably, the rotation range of the stop arm 2 is 0° to 90°. That is, when the stop arm is in the unlocked state (e.g. Figure 3 As shown), this is the initial state, with the stop arm rotating at 0°. When the stop arm is in the locked state (as shown), Figure 1 As shown in the figure, at this point the rotation angle of the stop arm reaches 90° and cannot be rotated any further.

[0033] Preferably, the two stop arms 2 are of the same specification and are symmetrically arranged to ensure that the two stop arms are subjected to roughly the same force, avoid unilateral overload, and thus improve the service life of the parking space lock anti-collision mechanism.

[0034] The rotatable connection between the stop arm 2 and the support 3 can be implemented in various ways. Here, a simple and easy-to-implement solution is provided: A rotating shaft 5 is further provided between the two supports 3, and each stop arm 2 is connected to this rotating shaft 5. The rotating shaft can rotate relative to the support, and there is no relative rotation between the stop arm and the rotating shaft. Specifically, the bottom end of each stop arm 2 is connected to the rotating shaft 5 via a flat key. Alternatively, limiting planes parallel to the axis can be machined at both ends of the rotating shaft, and through holes, which are irregularly shaped holes adapted to the limiting planes, can be provided at the bottom of the stop arm. When both ends of the rotating shaft pass through the irregularly shaped holes, the stop arm and the rotating shaft will not rotate. Of course, other methods can also be used to prevent relative rotation between the stop arm and the rotating shaft. Furthermore, since the two stop arms are connected to the same rotating shaft, it is convenient for the parking lock to drive the two stop arms to rotate synchronously via the same motor. It should be noted that in practical applications, the shaft can be prevented from moving along its axial direction by setting a retaining ring or other means. Since the means of preventing the shaft from moving axially is existing technology and is not an innovation of this invention, the corresponding structure will not be specifically drawn in the accompanying drawings.

[0035] Furthermore, each first abutting part 21 has a first abutting plane 211, and each second abutting part 41 has a second abutting plane 411 that is adapted to the corresponding first abutting plane. The significance of this setting is: (1) Compared with curved or irregular abutting structures, setting the abutting surface as a plane makes the processing simpler, the processing accuracy easier to control, and the two planes are easy to fit together when they abut, which can ensure the consistency of the abutting state each time it is raised and locked. (2) The abutting between the two planes (rather than point contact or line contact) can maximize the contact area, so that the impact force is evenly distributed to the stop and the base plate through the entire plane, avoiding stress concentration at a single point. (3) Irregular abutting structures may cause unstable abutting. The use of plane fitting in this application can make the first abutting part and the second abutting part abut more stably when the stop arm is impacted.

[0036] Furthermore, when each stop arm 2 is rotated upwards to the locked state, the first contact surface 211 faces forward (e.g., Figure 4 and Figure 5 (As shown); when each stop arm is turned downwards to the unlocked position, the stop arm faces forward. The "front side" referred to here is... Figure 3 From the left side of the viewpoint, the vehicle enters the parking space from... Figure 3The vehicle enters from the left to the right from the left side of the viewpoint. The "locked state" refers to the barrier arm being in a vertical position, forming a physical barrier to prevent other vehicles from occupying the parking space. The "unlocked state" refers to the barrier arm being in a horizontal position, eliminating the physical barrier and allowing authorized vehicles to enter and park normally. In this application, when each barrier arm rotates upwards to the locked state, the first contact surface faces the front of the base plate. This design ensures that after the barrier arm is impacted by another vehicle entering, the first contact surface cannot continue to rotate forward with the first contact part but instead abuts against the corresponding second contact surface. When each barrier arm rotates downwards to the unlocked state, the barrier arm faces the front of the base plate. This design ensures that when an authorized vehicle exits the parking space, even if the vehicle accidentally hits the barrier arm due to some reason (such as the barrier arm not being fully retracted), the barrier arm will move downwards accordingly, rather than causing the barrier arm to hook the vehicle and damage the vehicle and parking space lock.

[0037] Furthermore, each support 3 includes two lugs 31, the thickness of which is preferably 10-15 mm. The bottom end of each stop arm 2 is located between the two lugs on the same side (e.g., Figure 5 (As shown); the second abutment 41 is located between the two lugs 31 on the same side. The shaft passes through each lug, that is, each end of the shaft has two lugs providing support. The distance between the two lugs on the same side is greater than the thickness of the first abutment, so it will not interfere with the rotation of the first abutment. Since each end of the shaft is supported by two lugs, the shaft receives more stable support. When the stop arm is subjected to external force (such as a vehicle impact), the impact force transmitted by each stop arm to the shaft is evenly distributed to the two lugs on the same side. In addition, since the bottom end of the stop arm is located between the two lugs, the two lugs limit the bottom end of the stop arm, so that the stop arm will not undergo a large displacement along the axial direction of the shaft when it is impacted.

[0038] Furthermore, each stop 4 is fixedly connected (e.g., welded) to the two lugs 31 on the same side. This arrangement makes the two lugs and the stop on the same side form a rigid whole, further improving the strength and enabling it to withstand violent impacts.

[0039] Furthermore, a clearance groove 101 is provided on the base plate 1 at the bottom end of each stop arm. The clearance groove is provided to ensure that the first contact part does not interfere with the base plate during the rotation of the stop arm.

[0040] Accordingly, this utility model also provides a safe parking space lock, which includes a drive device and the aforementioned anti-collision mechanism. The drive device is used to drive the two stop arms to rotate. Furthermore, in practical applications, the safe parking space lock also includes some conventional components, such as: housing 91, main board (not shown in the figure), etc. These conventional components are not the innovation of this utility model and will not be specifically limited or described here. The housing 91 is connected to the base plate 1 by bolts.

[0041] In a preferred embodiment, the anti-collision mechanism of the parking space lock includes a rotating shaft 5 between two supports, with each stop arm connected to the rotating shaft. A driven gear 83 is mounted on the rotating shaft. The driving device includes a drive motor 81, with a driving gear 82 mounted on the main shaft. The driving gear 82 meshes with the driven gear 83.

[0042] Furthermore, in the safety parking lock, a baffle 92 is connected between the two stop arms 2, which can further improve the anti-collision performance. In addition, a camera (not shown in the picture) is installed on this baffle, with the camera lens facing the parking space entrance (i.e., Figure 3 (From the left side of the viewpoint), it can be used to capture real-time images of license plates of vehicles entering the vehicle. The camera is connected to the motherboard via a data cable. The motherboard has a built-in license plate recognition algorithm that can automatically identify whether a vehicle is authorized. If an authorized vehicle enters, the drive unit lowers the stop arm to the unlocked state; if an unauthorized vehicle enters, the stop arm remains locked.

[0043] Furthermore, a light-emitting panel 93 is also provided on the baffle 92, and a light-emitting device (such as LED beads, display screen, etc.) is provided on the light-emitting panel. The light-emitting device can convey the "occupancy status" of the parking space through different colors or flashing patterns, allowing users to quickly determine whether the parking space is available.

[0044] The aforementioned camera and light-emitting device are existing technologies. Their specific circuit connection methods (such as the interface connection between the camera and the motherboard, the circuit design of the LED beads, etc.) can be referred to conventional similar products, and will not be elaborated here.

[0045] The base plate of the safe parking lock is provided with multiple connection holes 102, and each connection hole is provided with a bolt to achieve a fixed connection between the base plate and the ground.

[0046] To facilitate understanding, the working principle is briefly described below.

[0047] When the stop arm rises to the "locked state," the first abutment part abuts against the corresponding second abutment part (considering assembly clearance, even if not fully abutted, the distance between the first and second abutment parts is very small). When an unauthorized vehicle enters, the stop arm remains locked. When the stop arm is violently impacted by an unauthorized vehicle, the first and second abutment parts abut against each other, transferring the impact force to the base plate. Because the stop block limits the rotation of the stop arm, preventing further rotation, the transmission mechanism connected to the stop arm (motor spindle, drive gear, driven gear, shaft, etc.) remains relatively stationary and will not be damaged. When an authorized vehicle enters the parking space, the stop arm lowers to the unlocked state, at which point the stop arm position will not interfere with the entry of the authorized vehicle. When an authorized vehicle drives out of a parking space, even if the stop arm is accidentally raised to a certain height, the contact point between the vehicle and the stop arm when the vehicle moves forward is located on the front side of the pivot. The torque generated is in the same direction as the downward direction of the stop arm, which will push the stop arm to rotate downward around the pivot until it fits against the floor. Therefore, the stop arm will not interfere with the vehicle's exit, nor will it cause damage to the vehicle's tires or chassis.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of the present utility model, and all such modifications or substitutions should fall within the protection scope of the present utility model.
