Description

Technical Field

[0001] This utility model relates to the field of parking lock technology, specifically to an improved parking lock structure. Background Technology

[0002] Parking locks are typically used to charge parking fees in public parking spaces such as those along roadsides. Among them, the barrier-type parking lock has a flip-up barrier. When a vehicle is detected entering the parking space, the barrier flips up so that the bottom of the barrier faces the wheel of the vehicle entering the parking space, preventing the vehicle from driving out. After payment is completed by scanning a code, the barrier can be lowered.

[0003] In a common parking lock structure, as shown in the announcement number CN114786399A, a parking lock housing with a waterproof cable outlet is divided into multiple chambers. The first chamber is used to house the battery and control circuit board, the second chamber is used to install the motor and transmission components, and the third chamber is used to install a water level sensor to detect whether the parking lock is submerged in water. This type of parking lock design has several drawbacks: First, because parking locks are typically installed in harsh outdoor environments such as roads, their waterproofing requirements are extremely high. When a water level sensor is installed in the third chamber, rainwater needs to be allowed to enter. Simultaneously, the water level sensor in the third chamber needs to be electrically connected to the first chamber, posing a significant challenge to the waterproofing of the chassis. Second, the battery and control circuit board are located in the first chamber. Due to space limitations, the battery capacity is limited. Even with a solar panel on the top of the chassis, frequent battery replacement and maintenance are required, resulting in very high maintenance costs during large-scale operation. Furthermore, each time the chassis is opened for battery replacement, the waterproofing performance of the chassis is compromised. Third, the chassis is relatively long and tall, making it prone to collisions with car doors or tripping hazards when the vehicle chassis is low. Therefore, it is necessary to improve this type of parking lock structure. Utility Model Content

[0004] The purpose of this invention is to provide an improved parking lock structure to enhance waterproof performance and reduce maintenance costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An improved parking lock structure includes a mounting base plate for fixing the parking lock to the ground, a baffle and a platform mounted parallel to the mounting base plate, a main unit and a mounting seat located at both ends of the baffle for rotatably mounting the baffle, a drive device located in the main unit for driving the baffle to flip and lift, and a battery assembly for power supply. It also includes a multi-mode sensor assembly that can be used for vehicle entry / exit and water level detection. The battery assembly and the multi-mode sensor assembly are both located in the platform, and the detection window of the multi-mode sensor assembly protrudes from the surface of the platform.

[0007] In a preferred embodiment, the multimode sensor assembly includes a geomagnetic sensor, a radar sensor, and an infrared sensor.

[0008] In a preferred embodiment, the main unit is a die-cast component, including a housing and a top cover. A first circumferential sealing ring is provided between the housing and the top cover. The bottom of the housing has a wire hole through which a power supply connection wire passes, and a cable sealing plug is provided in the wire hole to clamp and seal the power connection wire.

[0009] In a preferred embodiment, the top of the wire hole has an annular step that is higher than the top surface of the cable sealing plug, and the annular step has an adhesive sealant layer.

[0010] In a preferred embodiment, the driving device includes a motor, a lead screw coaxially mounted on the motor shaft, a slider mounted on the lead screw, a mounting shaft extending from both sides of the slider in a direction perpendicular to the lead screw, and a parallel swing arm mechanism with a groove at its upper end for sliding engagement with the mounting shaft; the side wall of the housing has a first mounting hole for fixed connection between the hinge shaft of the parallel swing arm mechanism and the rotation shaft of the baffle, and is provided with an oil seal to seal the first mounting hole.

[0011] In a preferred embodiment, the housing is designed to be symmetrical about left and right along its long axis, such that the other side wall of the housing has a second mounting hole corresponding to the hinge shaft, the outer wall of the housing has a sealing cover plate for sealing the second mounting hole, and a second sealing ring is provided between the sealing cover plate and the second mounting hole.

[0012] In a preferred embodiment, the wire hole extends symmetrically to the left and right sides of the bottom surface of the housing to the two outer side walls. The platform is a die-cast component, and the end of the platform adjacent to the housing is integrally formed with a protective cover for protecting the electrical connection wire that is seamlessly connected to the wire hole.

[0013] In a preferred embodiment, both the battery assembly and the multimode sensor assembly are provided with a sealed box on their exterior.

[0014] The beneficial effects of this utility model are as follows: By placing the battery assembly and multi-mode sensor assembly on the platform, on the one hand, the multi-mode sensor assembly can also be used for water level monitoring. Compared with the existing method of setting the water level sensor separately in the main unit, the waterproofing problem of the main unit can be completely solved, thereby avoiding damage to the motor and electronic control components due to moisture and significantly reducing maintenance costs. On the other hand, the battery assembly is not limited by the size of the main unit, which can increase the capacity, thereby reducing the frequency and cost of battery replacement and maintenance. Moreover, the height and length of the main unit are significantly reduced, which can avoid collisions with the vehicle door and reduce the chance of tripping over people. In addition, placing the multi-mode sensor assembly on the platform, compared with the existing method of placing it on the mounting base, can also prevent people from cutting the signal line through the gap between the platform and the mounting base.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the orientations or positional relationships indicated in the terminology are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, unless otherwise expressly specified and limited, terms such as "installation," "connection," "linking," and "fixing" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] refer to Figures 1 to 3As shown, an improved parking lock structure of this embodiment includes a mounting base plate 1 for fixing the parking lock to the ground, a baffle 2 and a platform 3 mounted parallel to the mounting base plate 1, a main unit 4 and a mounting base 5 disposed at both ends of the baffle 2 for rotatably mounting the baffle 2, a drive device 6 disposed in the main unit 4 for driving the baffle 2 to flip and rise, and a power supply battery assembly 7. It also includes a multi-mode sensor assembly 8 for vehicle entry and exit and water level detection. The battery assembly 7 and the multi-mode sensor assembly 8 are both disposed in the platform 3, and the detection window of the multi-mode sensor assembly 8 is exposed on the surface of the platform 3.

[0022] By mounting the battery assembly 7 and the multi-mode sensor assembly 8 on the platform 3, firstly, the multi-mode sensor assembly 8 can also be used for water level monitoring. Compared to the existing method of setting a water level sensor separately in the main unit 4, this completely solves the waterproofing problem of the main unit 4, thereby preventing the motor 61 and electronic control components from being damaged by moisture and significantly reducing maintenance costs. Secondly, the battery assembly 7 is not limited by the size of the main unit 4, so its capacity can be increased, thereby reducing the frequency and cost of battery replacement and maintenance. Moreover, the height and length of the main unit 4 are significantly reduced, which can avoid collisions with the vehicle door and reduce the chance of tripping over people. In addition, mounting the multi-mode sensor assembly 8 on the platform 3, compared to the existing method of mounting it on the mounting base 5, can also prevent people from cutting the signal line through the gap between the platform 3 and the mounting base 5.

[0023] In a preferred embodiment, the multi-mode sensor assembly 8 includes a geomagnetic sensor, a radar sensor, and an infrared sensor. Combining these three sensors with different detection principles improves the accuracy of vehicle entry and exit detection and effectively identifies abnormal situations. For example, it can comprehensively determine whether the vehicle is submerged by analyzing abnormal signals from each sensor, thus facilitating the lowering of the platform to allow the vehicle to exit.

[0024] In a preferred embodiment, the main unit chassis 4 is a die-cast component, including a chassis body 41 and a top cover 42. A first circumferential sealing ring is provided between the chassis body 41 and the top cover 42. The bottom of the chassis body 41 has a wire hole 43 through which a power supply connection cable passes, and a cable sealing plug 431 is provided in the wire hole 43 to clamp and seal the power connection cable. The die-cast chassis body 41 and top cover 42, combined with the first sealing ring and the cable sealing plug 431, can ensure the sealing of the main unit chassis 4 and achieve a high waterproof rating.

[0025] In a preferred embodiment, the top of the wire hole 43 has an annular step 432 that is higher than the top surface of the cable sealing plug 431, and the annular step 432 has an adhesive sealant layer. The adhesive sealant layer can be made of hot melt adhesive or the like, which can further improve the waterproof sealing performance at the wire hole 43.

[0026] In a preferred embodiment, the driving device 6 includes a motor 61, a lead screw 62 coaxially mounted on the shaft end of the motor 61, a slider 63 mounted on the lead screw 62, a mounting shaft 631 extending from both sides of the slider 63 in a direction perpendicular to the lead screw 62, and a parallel swing arm mechanism 64 with a groove at its upper end for sliding engagement with the mounting shaft 631. The side wall of the housing 41 has a first mounting hole 44 for fixedly connecting the hinge shaft 641 of the parallel swing arm mechanism 64 to the rotation shaft of the baffle 2, and an oil seal 441 for sealing the first mounting hole 44. The oil seal 441 ensures that the connection between the parallel swing arm mechanism 64 and the baffle 2 remains sealed with the housing 41 during rotation.

[0027] In a preferred embodiment, the housing 41 is designed symmetrically along its long axis, such that the other side wall of the housing 41 has a second mounting hole 45 corresponding to the hinge shaft 641. The outer wall of the housing 41 has a sealing cover plate 451 to seal the second mounting hole 45, and a second sealing ring is provided between the sealing cover plate 451 and the second mounting hole 45. The symmetrical design of the housing 41 and its internal structure facilitates installation and construction; that is, structures such as the baffle 2 and the platform 3 can be installed on the left or right side of the main unit housing 4 according to the parking space conditions. The sealing cover plate 451 ensures the sealing of the second mounting hole 45.

[0028] In a preferred embodiment, the wire hole 43 extends symmetrically to the left and right outer side walls of the outer bottom surface of the housing 41. The base 3 is a die-cast component, and a protective cover 31 for protecting the electrical connection wire is integrally formed at the end of the base 3 adjacent to the housing 41, seamlessly connected to the wire hole 43. The protective cover 31 extending from the base 3 and seamlessly connected to the wire hole 43 can prevent the electrical connection wire from being intentionally cut or damaged.

[0029] In a preferred embodiment, both the battery assembly 7 and the multimode sensor assembly 8 are externally provided with sealed boxes. The sealed boxes ensure the waterproof sealing of the battery assembly 7 and the sealed boxes installed within the platform 3.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
