Description

Technical Field

[0001] This utility model relates to the field of parking space lock technology, specifically a parking space lock for a parking lot. Background Technology

[0002] Parking space locks are mechanical blocking devices installed at the entrance of parking spaces. Their core function is to restrict vehicles from parking in unauthorized areas by using rigid barriers. Traditional parking space locks are mainly divided into three categories: manual key type, remote control signal control type, and automatic induction type. Among them, the automatic induction type uses radio frequency identification or Bluetooth technology to achieve the function of "lock opens when the car arrives and locks close when the car leaves". Although the control methods are becoming increasingly intelligent, their core blocking structure still relies on a single-layer metal frame, such as D-type locks and O-type locks, using metal materials with a yield strength of ≥235MPa, and achieving vehicle restriction through physical rigid contact.

[0003] However, taking the mainstream D-type lock as an example, although its longitudinal compressive strength can reach 30kN, its lateral strength drops sharply to less than 30% of the longitudinal strength (about 9kN). When a vehicle crashes at an angle at a speed of 5km / h, the impact energy is concentrated in a local area of ​​the lock spine, resulting in a plastic deformation rate of over 52% for the lock body. The frame welds form stress concentration points due to right-angle connections, with a cracking probability exceeding 40%. In open-air environments, ordinary iron plates or angle steel are prone to rust and corrosion, and after frequent impacts, the lock rod twist rate reaches 65%. In addition, the traditional structure is insufficient in multi-directional stress scenarios: the frame twist deformation is ≥8mm during lateral scraping, the lock door mis-opening rate is >25% during oblique impacts, and metal fatigue cracks lead to an average of more than 3 repairs per year. Therefore, traditional parking locks, due to their structural defects, cannot effectively stop vehicles that are traveling too fast or are too large.

[0004] Therefore, the industry urgently needs a parking lock device with anti-collision capabilities to improve its own strength and effectively block some vehicles that are too fast and have a large impact force. Utility Model Content

[0005] The main purpose of this utility model is to provide a parking space lock that can at least solve the problem that traditional parking space locks in the present technology have poor impact resistance and cannot effectively prevent collisions due to their own structural defects.

[0006] To achieve the above objectives, this utility model provides a parking space lock comprising: two blocking components arranged in pairs facing each other; each blocking component includes a base and a blocking plate movably mounted on the base; the two blocking components have a triangular vertical cross-section that can cooperate and support each other to block the car chassis in a first working state and a second working state that allows the car chassis to pass through; a supporting component disposed between the two blocking components to support the blocking plate when the blocking components are in the first working state; and a locking component disposed on the blocking components to control the switching of the blocking components from the first working state to the second working state, thereby blocking or allowing the car chassis to pass through.

[0007] Furthermore, the barrier component is provided with a guide member that allows the barrier plate to move on the base so that the barrier component is in a first working state or a second working state.

[0008] Furthermore, the base is provided with a groove for accommodating the barrier plate so that the barrier component can enter the second working state. The guide component includes a guide groove provided on the two inner side walls of the groove and a rod that passes through one end of the barrier plate and can cooperate with the guide groove. The two ends of the rod are rotatably installed in the guide groove.

[0009] Furthermore, the locking component includes: an insert groove, which is located on a plate groove at the lower end of the guide groove so that a rod moving to the end of the guide groove falls into the insert groove; an elastic component, which is located at the bottom of the insert groove so that the rod falling into the insert groove rebounds back onto the guide groove; and a locking pin, which is extendable or retractable and located on the guide groove corresponding to the insert groove. When the locking pin is in the extended state, the rod is locked into the insert groove; when the locking pin is in the retracted state, the rod falling into the insert groove can rebound back onto the guide groove under the action of the elastic component to guide its movement on the guide groove. When both rods move to the end of the guide groove and fall into the insert groove, the other free ends of the two blocking plates contact each other, and the blocking component enters a first working state; when the two rods move to the other end of the guide groove, the blocking plates can be laid flat on the plate groove, and the blocking component enters a second working state.

[0010] Furthermore, the two sides of the supporting component are fixedly connected to the bottom of the two bases respectively. The supporting component also includes: a support; the support is connected to the base and abuts against the embedded groove to limit the rod; a first support member, which is ring-shaped and can be vertically lifted and lowered on the support; a second support member, which can be vertically lifted and lowered on the support corresponding to the hollow part inside the ring of the first support member; wherein, the support is provided with a plurality of cylinders corresponding to the first support member and the second support member to raise the first support member and the second support member to abut against the two blocking plates or to lower the first support member and the second support member onto the support.

[0011] Furthermore, the barrier is equipped with handles.

[0012] Furthermore, the base is provided with multiple screw holes to fix the barrier components to the ground.

[0013] The parking space lock using this utility model includes: two blocking components arranged in pairs facing each other; each blocking component includes a base and a blocking plate movably mounted on the base; the two blocking components have a triangular vertical cross-section that can cooperate and support each other to block the car chassis in a first working state and a second working state that allows the car chassis to pass through; a supporting component is located between the two blocking components to support the blocking plate when the blocking components are in the first working state; and a locking component is located on the blocking components to control the switching of the blocking components from the first working state to the second working state, thereby blocking or allowing the car chassis to pass through. The parking space lock of this utility model significantly improves the anti-collision capability through the synergistic effect of multi-level structures. The triangular cross-section structure of the double blocking components achieves a multi-dimensional breakthrough in impact resistance. Through topological optimization of the triangular geometric configuration, the linear force mode of the traditional D-type lock is transformed into a spatial force coupling effect. When a longitudinal impact occurs, the hypotenuse of the triangle forms a 45-60° support angle with the ground through the base. The longitudinal impact force is decomposed into a diagonal compressive force and a horizontal shear force, with more than 75% of the energy transferred to the foundation through the hypotenuse. Compared to the vertical bearing mode of the D-type lock, local stress concentration is reduced by 62%. This spatial force component mechanism allows the structure to withstand a 30kN impact with a maximum deformation of only 1.2mm, while the D-type lock would have undergone plastic deformation under the same conditions. The support component makes full use of the surplus space inside the triangle, which plays a further reinforcing role. Finally, the locking device controls the entire blocking component. This invention forms a more stable triangular blocking structure, providing more powerful blocking for the car chassis, thus solving the problem that traditional parking locks in the prior art have poor impact resistance and cannot effectively block impacts due to their structural defects.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This utility model discloses a parking space lock, such as Figures 1 to 4As shown, the parking space lock includes: two blocking components 10 arranged in pairs facing each other; each blocking component 10 includes a base 11 and a blocking plate 12 movably mounted on the base 11; the two blocking components 10 have a triangular vertical cross-section that can cooperate and support each other to block the car chassis in a first working state and a second working state that allows the car chassis to pass through; a support component 20 is disposed between the two blocking components 10 to support the blocking plate 12 when the blocking component 10 is in the first working state; and a locking component 30 is disposed on the blocking component 10 to control the switching of the blocking component 10 from the first working state to the second working state, thereby blocking or allowing the car chassis to pass through; the parking space lock of this utility model significantly improves the anti-collision capability through the synergistic effect of multi-level structures, and the triangular cross-section structure of the double blocking components 10 achieves a multi-dimensional breakthrough in impact resistance performance. Through the topological optimization of the triangular geometric configuration, the linear force mode of the traditional D-type lock is transformed into a spatial force coupling effect. When a longitudinal impact occurs, the hypotenuse of the triangle forms a 45-60° support angle with the ground through the base 11. The longitudinal impact force is decomposed into a diagonal compressive force and a horizontal shear force, with more than 75% of the energy transferred to the foundation through the hypotenuse. Compared with the vertical bearing mode of the D-type lock, the local stress concentration is reduced by 62%. This spatial force component mechanism allows the structure to withstand a 30kN impact with a maximum deformation of only 1.2mm, while the D-type lock would have undergone plastic deformation under the same conditions. The support component makes full use of the surplus space inside the triangle, which plays a further reinforcing role. Finally, the locking device controls the entire blocking component 10. This utility model forms a more stable triangular blocking structure, which provides more powerful blocking for the car chassis, thus solving the problem that traditional parking locks in the prior art have poor impact resistance and cannot effectively block impacts due to their own structural defects.

[0023] Furthermore, the blocking component 10 is provided with a guide 13 that guides the blocking plate 12 to move on the base 11 so that the blocking component 10 is in a first working state or a second working state; the guide 13 ensures stability during the movement process, so that the blocking component 10 remains stable during the switching between the first working state and the second working state, avoiding deviations after long-term use, which would affect the working effect.

[0024] Furthermore, the base 11 is provided with a groove to accommodate the barrier plate 12 so that the barrier component 10 can enter the second working state. The barrier plate 12 can be placed flat on the groove. At this time, the height of the barrier component 10 does not exceed 8cm, so as not to affect the passage of the car chassis. The guide component 13 includes guide grooves 131 provided on the two inner side walls of the groove and a rod 132 that passes through one end of the barrier plate 12 and can cooperate with the guide groove 131. The two ends of the rod 132 are rotatably installed in the guide groove 131. The rod 132 is provided to prevent the barrier plate 12 from deflecting and getting stuck when it slides on the groove.

[0025] Furthermore, such as Figures 1 to 4 As shown, the locking component 30 includes: an embedding groove 31, which is precision machined from high-strength alloy steel and located on the plate groove at the lower end of the guide groove 131. Its inner wall is specially hardened to a hardness of HRC55-60, so that the rod 132 moving to the end of the guide groove 131 can accurately fall into the embedding groove 31, ensuring a positioning accuracy of ±0.1mm; an elastic component 32, which is composed of multiple sets of disc springs connected in series and located at the bottom of the embedding groove 31. It has non-linear stiffness characteristics and can provide progressive buffering when the rod 132 falls in, so that the rod 132 falling into the embedding groove 31 can smoothly rebound onto the guide groove 131, with a rebound efficiency of over 95%; and a locking pin 33, which is driven by an electric push rod and can intelligently control its extension or shortening. It is located on the guide groove 131 corresponding to the embedding groove 31, and the push rod stroke positioning accuracy is ±0.05mm. When the locking pin 33 is in the extended state, its wedge-shaped locking tongue at its end forms surface contact with the rod 132, firmly locking the rod 132 into the insertion groove 31. The locking force can reach 3kN, far exceeding the 0.5kN level of traditional mechanical locks. When the locking pin 33 is in the shortened state, the rod 132, which has fallen into the insertion groove 31, can rebound to the guide groove 131 under the precise control of the elastic component 32. The entire process takes only 0.5 seconds, achieving rapid unlocking. This locking mechanism is specially designed with double insurance: mechanical locking ensures safe locking in the event of a power outage, and electric control enables intelligent remote operation. When both rods 132 move to the end of the guide groove 131 and fall into the embedded groove 31, the other free ends of the two barrier plates 12 interlock with each other through precision-machined inclined surfaces, forming a stable triangular support structure. At this time, the barrier component 10 enters the first working state, and the overall impact resistance of the structure is increased to 2.5 times that of the traditional design. When the two rods 132 move to the other end of the guide groove 131, the barrier plate 12 can be completely laid flat on the anti-scratch plate groove, so that the barrier component 10 quickly enters the second working state. At this time, the overall height is only 10cm, which greatly reduces the risk of chassis scraping when the vehicle passes.

[0026] Furthermore, such as Figures 1 to 4As shown, the two sides of the support component 20 are rigidly fixed to the bottom of the two bases 11 by high-strength bolts. This connection method has been optimized by finite element analysis to ensure that the stress concentration factor at the connection is controlled below 1.2 when subjected to a 30kN impact load. The support component 20 also includes: a support 21, which is made of ductile iron QT500-7 and undergoes aging treatment to eliminate internal stress. It is connected to the base 11 through a precision-machined dovetail groove and simultaneously abuts against the embedded groove 31 to form a three-point positioning system, which can control the displacement deviation of the rod 132 within ±0.3mm; a first support 22, which is a heat-treated 42CrMo alloy steel ring structure with an inner diameter tolerance controlled at H7 grade. It can be vertically lifted and lowered along the precision-ground guide rail on the support 21, with a lifting stroke of up to 150mm and a repeatability accuracy of ±0.1mm; and a second support 23, which is made of high-strength aluminum alloy and undergoes anodizing treatment. It can be vertically lifted and lowered on the support 21 corresponding to the precision-machined hollow part inside the ring of the first support 22, forming a nested support structure with the first support 22, thereby increasing the overall rigidity by more than 40%. The support 21 is equipped with multiple servo cylinders 24 corresponding to the first support member 22 and the second support member 23. These cylinders 24 have an IP67 protection rating and are equipped with high-precision magnetic scale position feedback. They can make the first support member 22 and the second support member 23 rise rapidly within 0.5 seconds and accurately abut against the two blocking plates 12, providing a maximum support force of 15kN, or make the first support member 22 and the second support member 23 fall smoothly to the preset buffer pad position on the support 21, achieving impact-free reset. The locking pin 33 and the cylinders 24 can be remotely controlled by existing remote control devices.

[0027] Furthermore, the barrier plate 12 is equipped with a handle 121, which makes it convenient for the car owner to move the barrier plate 12 by means of the handle 121.

[0028] Furthermore, the base 11 is provided with multiple screw holes 111 distributed according to the principle of equal strength. These screw holes 111 use M12 standard threads and are galvanized for rust prevention. When used with special chemical anchors, they can reliably fix the barrier component 10 under various ground conditions, with a pull-out force of more than 20kN. The screw holes 111 can also be provided with a drainage groove structure to prevent water accumulation and corrosion.

[0029] In practical use, the vehicle owner can manually pull up the barrier plate 12 via the handle 121. The rod 132 on the barrier plate 12 is guided and moved to the rear end within the guide groove 131, falling into the embedded groove 31. The locking pin 33 above extends to abut against the rod 132 to prevent it from rebounding. When the hands are released, the two barrier plates 12 come together under the action of gravity and support each other to form a stable triangular structure. The cylinder 24 is activated to raise the first support member 22 and the second support member 23. The support member 23 fits tightly against the inner walls of the two barrier plates 12, further enhancing the stability of the system. At this time, the parking lock will block the car chassis. When the car owner needs to use it, the remote control cylinder 24 and locking column 33 are used to lower the cylinder 24 and retract the locking column 33. At this time, the rod 132 rebounds to the guide groove 131 under the action of the elastic component 32. The two barrier plates 12 slide downward to the sides under the action of gravity, entering the second working state. The car owner drives the car into the parking space to complete the use.

[0030] The electrical components described in this invention are controlled automatically by a controller. The controller circuit can be easily programmed by those skilled in the art. The power supply is also common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
