Description

Technical field:

[0001] The invention relates to an intelligent advertising parking space ground lock, and in particular to a straight-rod swing-arm type anti-theft intelligent advertising parking space ground lock. Background technology:

[0002] With the continuous progress of society, cars have become people's main means of transportation. The increase in the number of cars has directly led to a shortage of parking spaces. With the tension between supply and demand, the phenomenon of forced occupation of parking spaces has occurred repeatedly. In order to solve this problem, the parking space locks on the market currently include manual parking space locks, remote control parking space locks, and the currently more popular smart parking space locks. Although they have different appearances, they have many common features, such as: an alarm sounds when a parking space is occupied, resulting in the parking space not being truly guarded and the battery is not durable; the swing arm is made of rigid material and is rigidly connected to the base, resulting in a collision between the vehicle and the lock, causing great losses to both parties; the mechanical structure is complex, resulting in more power consumption during transmission and high processing costs; the mechanical mechanism is limited, resulting in easy damage to the drive motor gear; there is no billboard effect, etc.

[0003] The invention patent with application number 201510563189.X provides a pull rod type anti-collision remote control parking lock, including a crank bracket, a crank bracket, an articulated crank mechanism, an articulated pull rod and a rocker arm top which are articulated in sequence, and a motor drives the crank mechanism, thereby driving the pull rod to drive the rocker arm to close and open the parking space.

[0004] The disadvantages of the above invention patent are: 1. Due to the limitation of mechanical structure, the motor consumes more power when running and the reducer is easy to break teeth; 2. The main transmission part is exposed, which is easy to rust or be affected by the natural environment, resulting in abnormal use; 3. The rocker arm and the ground lock body are rigidly connected. When the vehicle collides with the ground lock, the vehicle and the ground lock are inevitably damaged, especially the ground lock is extremely difficult to repair or even scrapped as a whole, making it difficult to deal with various problems when parking; 4. Through some common tools and conventional means, the lock can be easily dismantled or even pried without violence without opening the outermost protective shell; 5. There is no advertising effect. Therefore, it is not the best solution. Summary of the invention:

[0005] The technical problem to be solved by the present invention is to provide a straight-rod swing-arm anti-theft intelligent advertising parking space ground lock in view of the deficiencies of the above-mentioned prior art.

[0006] The technical solution adopted by the present invention is:

[0007] A straight-rod swing-arm type anti-theft intelligent advertising parking lock, a transmission bracket is fixed on a base, a transmission shaft is installed on the transmission bracket, a motor output shaft is connected to the transmission shaft, a main swing arm is mounted on the transmission shaft, a cam mechanism is also fixedly connected to the transmission shaft, the cam mechanism includes a cam and a swing pin fixed on the cam, the swing pin is in contact with the main swing arm for transmission; a bayonet pin sliding groove is provided at the lower part of the transmission bracket, a bayonet pin which is slidably matched with the cam is mounted in the bayonet pin sliding groove, the bayonet pin end is fixedly connected to one end of a tension spring, and the other end of the tension spring is fixedly connected to the transmission bracket.

[0008] Furthermore, a swing pin sliding groove is provided on the main swing arm, the swing pin is sleeved in the swing pin sliding groove, a clamp arm is protruded at the front end of the lower part of the main swing arm, a clamping slot is formed below the clamp arm, and the clamp arm and the clamping slot cooperate to position the clamp pin. Under the action of the cam and the tension spring force, the clamp pin can be disengaged from or enter the clamping slot through the forward and reverse rotation of the cam, thereby achieving locking in the unlocking direction when closing the lock.

[0009] Furthermore, a swing pin track groove is provided on the transmission bracket, and the swing pin is sleeved in the swing pin track groove of the transmission bracket.

[0010] Furthermore, a sub-bracket is fixed on the base, a driven shaft is mounted on the sub-bracket, a sub-swing arm is mounted on the driven shaft, the sub-swing arm is fixedly connected to the swing frame, and the detector bracket is located on the swing frame and fixedly connected to the swing frame.

[0011] Furthermore, a torsion spring is mounted on the driven shaft, and the side force arms at both ends of the torsion spring are respectively clamped on the auxiliary swing arm and the auxiliary bracket. The torsion spring can store energy with the swing parts such as the straight rod and the billboard under the action of gravity when unlocking, and release energy when locking, thereby reducing the turning torque of the motor, thereby reducing the current, extending the service life of the motor and the battery, and making the turning process more stable.

[0012] Furthermore, a main limit block is provided on the top of the transmission bracket, and a main limit slot corresponding to the main limit block is provided on the swing frame; a secondary limit block is provided on the top of the secondary bracket, and a secondary limit slot corresponding to the secondary limit block is provided on the swing frame. When the locking is completed, the above device can be locked in the upper limit position in the locking direction.

[0013] Furthermore, a detector bracket is mounted on the swing frame, the lower end of the detector bracket is fixedly connected to the threading frame, and a detector is mounted on the detector bracket. The detector detects whether there is a car parked in the parking space, and the detector is preferably an ultrasonic detector. The detector passes through the detector bracket, the swing frame, the threading machine and the driven shaft, which can greatly prevent the winding effect caused by the rotation of the detector.

[0014] Furthermore, a battery is fixed on the base, and the battery, motor, transmission bracket, transmission shaft, main swing arm, cam mechanism, bayonet, tension spring, auxiliary bracket, driven shaft, auxiliary swing arm, swing frame and torsion spring are all installed in the pressure-resistant shell, and the pressure-resistant shell is fixedly connected to the base.

[0015] Furthermore, the main swing arm and the swing frame, the detector bracket, the straight rod, the billboard fixing frame, and the billboard are fixedly connected in sequence.

[0016] Furthermore, the straight rod and the detector bracket are of a split structure, the straight rod is made of non-metallic material or the detector bracket and the straight rod are connected by a safety pin. The above solution can effectively reduce the damage to the vehicle and the ground lock when the vehicle collides with the closed parking ground lock, greatly reducing the maintenance costs of both parties, and the parking ground lock can continue to be used after the straight rod is replaced.

[0017] Working principle:

[0018] The motor drives the transmission shaft and drives the cam mechanism to rotate together through the transmission shaft. First, the rotation of the cam mechanism causes the bayonet pin to bypass the bayonet arm and disengage from or enter the bayonet port. At the same time, the swing pin fixedly connected to the cam mechanism drives the main swing arm and its connecting parts to rotate, thereby realizing the opening / closing of the parking space lock. When unlocking, the rotation of the motor drives the cam mechanism on the transmission shaft and the swing pin fixedly connected to the cam mechanism to rotate in the swing pin sliding groove of the active swing arm first. When the cam mechanism rotates a certain angle, its cam causes the bayonet pin to push off the bayonet port and disengage from the bayonet arm. At this time, the swing pin rotates to the limit position of the swing pin sliding groove, and then drives the main swing arm and its related fixed parts to continue to rotate. Until the billboard is parallel to the ground; when locking, the motor rotates to drive the cam mechanism on the transmission shaft and the swing pin fixedly connected to the cam mechanism to rotate in the opposite direction first in the swing pin sliding groove of the main swing arm. When the swing pin rotates to the other extreme position of the swing pin sliding groove, the swing pin drives the main swing arm and its related fixed parts to continue to rotate in the opposite direction. During this process, the cam in the cam mechanism always supports the bayonet pin and stays away from the bayonet arm and the bayonet position below, so that the main swing arm continues to rotate in the opposite direction. When the main swing arm rotates to the locked position, the bayonet pin slides into the bayonet under the action of the cam and the tension spring force, thereby realizing positioning in the unlocking direction. The tension spring has a pre-tightening force to prevent the bayonet pin from escaping from the bayonet.

[0019] Features and effects of the present invention:

[0020] 1. The present invention adopts a straight-rod swing-arm structure to replace the crank-connecting rod mechanism of the traditional technology. The straight-rod swing-arm structure has a simple structure, is easy to drive with a motor, has low power consumption, consumes less electricity, and has a long battery life. However, when the crank-connecting rod of the traditional technology finally changes from an arch shape to a straight shape, a large thrust is required to overcome the spring tension to achieve this. Therefore, the motor consumes a lot of power, consumes a lot of electricity, and the battery life is short.

[0021] 2. The present invention adopts a straight-rod swing-arm structure, and its motor, battery and transmission parts can all be installed in the pressure-resistant shell to avoid sun exposure, rain, dirt, dust, rust, corrosion and damage. At the same time, the protection of the pressure-resistant shell can also prevent damage by car crushing and human damage, and has a long service life. However, due to the requirements of stability and balance, the crank-connecting rod mechanism of the traditional technology can only be made into a three-point hinged structure on both sides and in the middle, with a large span, and it is impossible to install all the transmission parts in the pressure-resistant shell. Some of the transmission parts must be exposed to the outside, which is easily damaged by the sun, rain, dust, corrosion, and rust, and is easily crushed by cars and human damage, with a short service life and high maintenance and replacement costs.

[0022] 3. The straight rod in the present invention is made of non-metallic materials or uses a safety pin connection mechanism, replacing the rigid connection of traditional technology. In this way, when hit by a vehicle, the structure of the present invention can protect the ground lock motor and transmission components from damage, and the vehicle will not be damaged. This structure of the present invention is a humanized design. Due to the rigid structure of traditional technology, both the parking lock and the vehicle are easily damaged, and the parking lock is extremely difficult to repair, or even scrapped as a whole, which increases the cost of use and affects the performance.

[0023] 4. The present invention installs the motor, battery and transmission components in a pressure-resistant housing, which is sealed by fastening bolts and anti-theft locks to prevent the lock from being easily dismantled or pried without opening the pressure-resistant housing, and has good protection performance. In the traditional technology, part of the transmission components are exposed to the outside, which is very easy to be dismantled and pried, and has poor protection performance.

Specific implementation method:

[0035] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0036] like Figure 1 , Figure 2 As shown, the structure of the present invention includes: a billboard 1, a billboard fixing frame 32, a straight rod 2, and a pressure-resistant shell 3, wherein the pressure-resistant shell 3 is a hollow shell made of a special material, which can effectively prevent the rolling of automobile tires and protect the internal mechanical structure and electronic equipment. The pressure-resistant shell 3 is equipped with a motor control box 4, a battery 5 and a transmission component, which are all installed on a base 6. A motor is installed in the motor control box 4, and the battery 5 supplies power to the motor.

[0037] Combination Figure 3 — Fig. 9 As shown, the specific mechanical structure of the present invention is as follows: a transmission bracket 9 is installed on the base 6, a transmission shaft 12 is installed on the transmission bracket 9, one end of the transmission shaft 12 is connected to the motor, and the other end of the transmission shaft 12 is sleeved with a main swing arm 8, the main swing arm 8 is a hollow structure, and a cam mechanism 10 is arranged inside; the cam mechanism 10 contains a swing pin 7 that is fixedly connected, and the cam mechanism 10 is fixedly connected to the transmission shaft 12; the main swing arm 8 is provided with a swing pin sliding groove 28, a clamping arm 29 and a clamping mouth 30; the transmission bracket 9 is provided with a swing pin track groove 19 and a clamping pin sliding groove 20, and tension springs 13 are fixed on both sides of the clamping pin sliding groove 20, one end of the tension spring 13 is fixed on the transmission bracket 9, and the other end is connected to the clamping pin 11, and the clamping pin 11 can slide in the clamping pin sliding groove 20.

[0038] The main swing arm 8 is fixedly connected to the swing frame 14, the detector bracket 24, the straight rod 2, the threading frame 31, and the auxiliary swing arm 15. The auxiliary swing arm 15 is connected to the auxiliary bracket 16 through a driven shaft 17. A torsion spring 18 is provided in the auxiliary bracket 16. The torsion spring 18 is sleeved on the driven shaft 17. The side force arms at both ends of the torsion spring 18 are respectively clamped on the auxiliary swing arm 15 and the auxiliary bracket 16.

[0039] The transmission bracket 9 and the auxiliary bracket 16 are also provided with a main limit block 21 and an auxiliary limit block 23, and the swing frame 14 is provided with a main limit slot 27 and an auxiliary limit slot 26 that cooperate therewith.

[0040] The detector bracket 24 is further provided with a detector 25 .

[0041] The driven shaft 17 is a hollow structure, and the connecting wire of the detector 25 can pass through the swing frame 14, the threading frame 31 and the driven shaft 17 to reach the motor control box 4 to prevent the wiring of the detector 25 from causing winding when the ground lock is turned over.

[0042] Figure 1 The parking space ground lock is in the locked state. When unlocking, the motor rotates forward, and the motor drives the transmission shaft 12, the cam mechanism 10 and the swing pin 7 in the cam mechanism 10 to rotate together. At this time, the swing pin 7 slides in the swing pin sliding groove 28, so that the cam mechanism 10 and the fixed parts contained therein rotate with the main swing arm 8 and its fixed parts first. When the swing pin 7 slides in the swing pin sliding groove 28, the cam mechanism 10 rotates a certain angle. At this time, the cam 22 in the cam mechanism 10 makes the latch pin 11 disengage from the latch 30 in the main swing arm 8 and bypass the latch arm 29. At this time, the swing pin 7 is in the extreme position of the swing pin sliding groove 28 in the main swing arm 8. As the motor continues to rotate, the swing pin 7 contacts the extreme position of the swing pin sliding groove 28 and then drives the main swing arm 8, the swing frame 14, the auxiliary swing arm 15, the detector bracket 24, the threading frame 31, the straight rod 2, the billboard fixing frame 32 and the billboard 1 to continue to rotate until the unlocked state, completing the unlocking process.

[0043] Fig. 9The parking space ground lock is in the unlocked state. When the lock is closed, the motor rotates in the opposite direction, and the motor drives the transmission shaft 12. The transmission shaft 12 drives the cam mechanism 10 and the swing pin 7 contained therein to rotate together. When the swing pin 7 rotates to another extreme position of the swing pin sliding groove 28, the swing pin 7 drives the main swing arm 8 and its fixed parts to rotate together. After rotating to a certain angle, the cam 22 always supports the bayonet pin 11 and is away from the bayonet 30 below the bayonet arm 29. As the cam mechanism 10 and the main swing arm 8 continue to rotate to the locked state, the bayonet pin 11 slides into the bayonet 30 along the bayonet sliding groove 20 under the joint action of the cam mechanism 10 and the tension spring 13, completing the locking. At this time, the main limit slot 27 on the swing frame 14 contacts and matches with the main limit block 21 on the transmission bracket 9, and the secondary limit block 23 on the secondary bracket 16 contacts and matches with the secondary limit slot 26 on the swing frame 14, playing the role of mechanical limit.

[0044] In addition, in the present embodiment, when the parking space ground lock is in the locked state, it can effectively prevent others from manually turning it externally, and the specific method is as follows: when the locking is completed, the locking direction limit is achieved through the contact between the main limit slot 27 and the auxiliary limit slot 26 and the main limit block 21 and the auxiliary limit block 23, thereby realizing the mechanical limit in the locking direction; when the lock is forcibly unlocked, the external billboard 1, the billboard fixing frame 32, the straight rod 2 and the detector bracket 24 drive the swing frame 14, the main swing arm 8, and the cam mechanism 10 to rotate together. At this time, the pin 11 has not been pushed away from the bayonet 30, and the arm 29 in the main swing arm 8 is stuck by the pin 11, thereby achieving the function of limiting and anti-theft.

[0045] In addition, in this embodiment, a torsion spring 18 is provided inside the auxiliary swing arm 15. The torsion spring 18 is sleeved on the driven shaft 17, and the side force arms at both ends are respectively clamped on the auxiliary swing arm 15 and the auxiliary bracket 16. The compression and rebound of the torsion spring 18 are realized with the rotation of the auxiliary swing arm 15. When unlocking, the torsion spring 18 stores energy under the combined action of the torque generated by the motor and the flipping torque generated by the straight rod 2, the billboard fixing frame 32, and the billboard 1 due to gravity; when locking, the torsion spring 18 releases energy and works together with the reverse torque generated by the motor to flip the straight rod 2, the billboard fixing frame 32, and the billboard 1 together. The setting of this torsion spring 18 can make the motor more energy-saving and the flipping process more stable.

[0046] In addition, the straight rod 2 is preferably made of non-metallic material with a lower material strength than the detector bracket 24 connected thereto. When the lock is closed and the vehicle collides with the ground lock, the straight rod 2 breaks first, protecting the internal transmission mechanism of the ground lock and minimizing the loss of the vehicle. It is also convenient to replace.

[0047] Alternatively, the material strength of the straight rod 2 is equal to or greater than the material strength of the detector bracket 24, and is made of metal. The bolts at the connection between the straight rod 2 and the detector bracket 24 are non-metallic or provided with safety pins. When the vehicle collides with the ground lock, the non-metallic bolts or safety pins break first.

[0048] In addition, the detector 25 for detecting the presence of a vehicle is preferably an ultrasonic detector, which is mounted on a detector bracket 24. When a collision occurs and the straight rod 2 is separated from the detector bracket 24, the detector 25 remains intact.
