Description

Technical Field

[0001] The utility model relates to the technical field of geomagnetic induction devices, in particular to a geomagnetic induction device for parking which is easy to maintain. Background Art

[0002] A geomagnetic sensor is a device that identifies vehicles by changes in the magnetic flux of the geomagnetic field. A coil with a high magnetic permeability iron core is buried under the road surface. When a vehicle made of metal material approaches or passes through the coil, the original constant magnetic flux lines passing through the coil change, generating a voltage in the coil. This voltage is amplified by a high-gain amplifier to drive the relay, sending out information that a vehicle has passed. Most properties use geomagnetic sensors to manage parking spaces within the community. The signals generated by the geomagnetic sensors are transmitted to the Internet of Things, and parking space statistics and vehicle parking billing functions are formed.

[0003] For example, the public document with application number 202123088895.3 discloses a geomagnetic induction device for parking that is easy to maintain. When the battery needs to be replaced, the utility model only needs to rotate the shell cover so that the locking rod leaves the lock slot and slides out of one side of the limit slot. At this time, the battery can be replaced very conveniently, avoiding the need to remove multiple screws connecting the shell and the shell cover to replace the battery, reducing the work intensity of the property staff and improving the work efficiency of the property staff. However, in the geomagnetic induction device for parking, the closure of the cover and the shell is only connected by rotating the locking rod and the lock slot, and then the sealing is performed by the tension of the spring. The car will vibrate the ground when it is in the parking space, which will cause the secondary reverse rotation of the cover, causing the locking rod to disengage from the lock slot. At this time, the vibration will cause the spring to oscillate up and down continuously, causing the cover to bounce up and down and collide continuously, making it difficult to stably install and use it in a closed manner. In addition, due to the restrictions of the spring and each rod body, the distance that the cover moves up and opens is limited. When manually replacing the battery, it can only be pressed in the small space formed between the cover and the shell after it is opened, which is still inconvenient for manual replacement of the battery and is not conducive to maintenance operations.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a geomagnetic induction device for parking that is easy to maintain is proposed. Utility Model Content

[0005] The utility model aims to provide a geomagnetic induction device for parking which is easy to maintain, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetic induction device for parking that is easy to maintain, comprising an assembly shell, a cover is arranged on the top of the assembly shell, four pins are evenly distributed and fixedly installed around the bottom of the surface of the cover, a positioning groove is provided below the surface of the pins, four slots are evenly distributed around the top of the outer surface of the assembly shell, a through cavity is provided above the outer surface of the assembly shell and below the slots, a thrust spring is fixedly installed on the bottom end of the inner surface of the through cavity, an insert block is fixedly installed on the upper end of the thrust spring, and a shift block is fixedly provided on the lower end of the front side of the surface of the insert block.

[0007] Preferably, the shape of the pin is set to be L-shaped, and the shape of the slot is also set to be L-shaped, and the L-shaped bottom end horizontal plate of the pin is the same size as the upper end opening of the slot.

[0008] Preferably, the upper end of the through cavity is communicated with the left side of the bottom end of the slot, and the upper end of the insert block passes through the through cavity and is located inside the slot, and the right side of the insert block inside the slot is set as an inclined surface.

[0009] Preferably, the surface of the shift block is slidably fitted into the interior of a through cavity, and the shift block passes through the through cavity and protrudes out of the assembly shell.

[0010] Preferably, a geomagnetic sensor is fixedly mounted in the middle portion below the surface of the cover, and a battery pack is mounted at the bottom end of the geomagnetic sensor.

[0011] Preferably, four damping spring rods are evenly distributed and fixedly disposed on the bottom end of the inner surface of the assembly shell, and the damping spring rods are composed of a damper and a telescopic spring.

[0012] Preferably, a movable plate is fixedly mounted on the upper end of the damping spring rod, and a soft pad is fixedly arranged above the surface of the movable plate, and the soft pad is in contact with the bottom end of the battery pack.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a pin, a positioning groove, a slot, a through cavity, a thrust spring, an insert block and a push block. After the pin is inserted into the bottom end of the slot, the cover is closed with the assembly shell, and then the cover is rotated to make the pin move to the left inside the slot, and the insert block is pushed downward by the inclined surface to squeeze the thrust spring. When the L-shaped left end of the pin fits the left end of the inner surface of the slot, the upper end of the insert block corresponds to the positioning groove. Under the pushing force of the thrust spring, the insert block is inserted into the positioning groove, so that the pin cannot rotate in the opposite direction, and the upper side is limited by the L-shaped side wall of the slot, and cannot be directly moved. The cover is directly pulled out from the upper end to open it, so that the cover and the assembly shell can be stably and firmly installed and closed, to prevent the vibration force of the car from causing the cover to rotate in the opposite direction and become loose. The shift block is manually pressed down to make the shift block drive the plug block to move out of the positioning slot. At this time, the cover is manually rotated in the opposite direction again to pull out the cover. The cover can be completely separated from the assembly shell, and the geomagnetic sensor and the battery pack can be completely taken out. The battery pack can be taken to any position for replacement, which increases the operating space for replacing the battery pack, greatly improves the convenience of replacing the battery pack, and improves work efficiency.

[0015] 2. The utility model provides a damping spring rod, a movable plate and a soft pad, so that a certain vibration is generated on the ground when the vehicle is running. The vibration is transmitted to the movable plate through the cover and various components. The movable plate will squeeze the damping spring rod and compress it when it is vibrated. The damper in the damping spring rod can buffer and brake the vibration force by using its own characteristics, thereby reducing the damage caused by the vibration force to the internal geomagnetic sensor and the battery pack, and improving the safety and stability during use. At the same time, the damping spring rod will be reset by using the telescopic spring to prepare for the next vibration buffering. When the damping spring rod pushes the movable plate to reset, the soft pad will contact the battery pack first. The soft pad can avoid secondary collision with the battery pack when the movable plate is reset, thereby preventing damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, a geomagnetic induction device for parking that is easy to maintain comprises an assembly shell 1, a cover 2 is arranged above the assembly shell 1, four pins 3 are evenly distributed and fixedly installed around the lower surface of the cover 2, a positioning groove 301 is provided below the surface of the pins 3, four slots 4 are evenly distributed around the upper surface of the assembly shell 1, a through cavity 5 is provided above the outer surface of the assembly shell 1 and below the slots 4, a thrust spring 6 is fixedly installed at the bottom end of the inner surface of the through cavity 5, an insert block 7 is fixedly installed at the upper end of the thrust spring 6, a shifting block 8 is fixedly provided at the lower end of the front side of the surface of the insert block 7, the shape of the pin 3 is set to be L-shaped, and the shape of the slot 4 is also set to be L-shaped, and the L-shaped bottom end horizontal plate of the pin 3 is the same size as the upper end opening of the slot 4, and the through cavity 5 is The upper end is connected with the left side of the bottom end of the slot 4, and the upper end of the insert block 7 passes through the through cavity 5 and is located inside the slot 4, and the insert block 7 is located inside the slot 4 and is arranged on the right side as an inclined surface, the surface of the shift block 8 is slidably fitted with the inside of the through cavity 5, and the shift block 8 passes through the through cavity 5 and protrudes outside the assembly shell 1, a geomagnetic sensor 9 is fixedly installed in the middle below the surface of the cover 2, and a battery pack 10 is installed at the bottom end of the geomagnetic sensor 9, four damping spring rods 11 are evenly distributed and fixed at the bottom end of the inner surface of the assembly shell 1, and the damping spring rod 11 is composed of a damper and a telescopic spring, a movable plate 12 is fixedly installed on the upper end of the damping spring rod 11, and a soft pad 13 is fixedly arranged above the surface of the movable plate 12, and the soft pad 13 fits with the bottom end of the battery pack 10.

[0023] Furthermore, the bottom end of the horizontal plate of the pin 3 is the same size as the upper opening of the slot 4, and the width of the vertical rod of the pin 3 is smaller than the vertical groove width of the slot 4, so that after the pin 3 is inserted into the bottom end of the slot 4, it can be rotated to the left for a second time, and the horizontal plate at the lower end of the pin 3 and the horizontal groove of the slot 4 are used to limit the upper and lower positions, so as to prevent the cover 2 and the assembly shell 1 from being pulled up and down and loosening.

[0024] Furthermore, the right side of one end of the plug block 7 located inside the slot 4 is set as an inclined surface. When the pin 3 rotates to the left, the inclined surface of the plug block 7 can be used to push the plug block 7 downward and converge into the through cavity 5, so that the horizontal plate of the pin 3 can be stably rotated for a second time to insert the left end of the horizontal groove of the slot 4 to perform upper and lower limit blocking.

[0025] Furthermore, the positioning groove 301 is provided at the bottom of the surface of the pin 3. After the pin 3 is inserted into the bottom end of the transverse groove, the positioning groove 301 corresponds to the through cavity 5. The sunken groove body of the positioning groove 301 loses the squeezing of the plug block 7, and then under the action of the thrust spring 6, the plug block 7 can be inserted into the positioning groove 301. The left side of the plug block 7 is a right-angled surface, so the pin 3 cannot rotate in the opposite direction to move the plug block 7 downward. The plug block 7 limits and fixes the secondary rotation insertion position of the pin 3 to prevent the pin 3 from rotating in the opposite direction and then slipping off and separating from the opening of the slot 4, which once again improves the stability of the installation of the cover 2, and the assembly of the cover 2 is also simpler and more convenient, and only requires insertion and rotation.

[0026] Furthermore, the shift block 8 passes through the through cavity 5 and is connected with the plug block 7, so that the shift block 8 moves downward to drive the plug block 7 to move downward and slide out of the positioning groove 301, and the limit of the plug block 7 is lost, so that the pin 3 can rotate in the opposite direction, thereby sliding out through the opening of the slot 4, and separating and disassembling the cover 2 and the assembly shell 1.

[0027] Furthermore, the geomagnetic sensor 9 and the battery pack 10 are integrally fixedly connected to the cover 2. After the cover 2 is disassembled and taken out, the geomagnetic sensor 9 and the battery pack 10 can be taken out together, and the battery pack 10 can be taken to any position for replacement, thereby increasing the operating space for replacing the battery pack 10, greatly improving the convenience of replacing the battery pack 10, avoiding the need to remove multiple screws connecting the shell and the shell cover to replace the battery pack 10, and improving work efficiency.

[0028] Furthermore, the soft pad 13 fits the battery pack 10 so that when the vibration force is transmitted, the soft pad 13 can effectively protect the battery pack 10 and prevent the movable plate 12 from directly contacting the battery pack 10 and causing bumps and damages.

[0029] Furthermore, when the movable plate 12 is vibrated, the vibration is transmitted and the damping spring rod 11 is squeezed. The damper of the damping spring rod 11 itself can effectively buffer and weaken the vibration force, thereby preventing the damage of the internal structure caused by the vibration.

[0030] Working principle: When using the geomagnetic induction device for parking that is easy to maintain, first, after the pin 3 is inserted into the bottom end of the slot 4, the cover 2 is closed with the assembly shell 1, and then the cover 2 is rotated to make the pin 3 move to the left inside the slot 4, and the inclined surface is used to push the plug block 7 to squeeze the thrust spring 6 downward. When the L-shaped left end of the pin 3 fits the left end of the inner surface of the slot 4, the upper end of the plug block 7 corresponds to the positioning groove 301. Under the pushing force of the thrust spring 6, the plug block 7 is inserted into the positioning groove 301, so that the pin 3 cannot rotate in the opposite direction, and the upper side is limited by the L-shaped side wall of the slot 4, and the cover 2 cannot be directly pulled out to the upper end to open, so that the cover 2 and the assembly shell 1 can be stably and firmly installed and closed, so that the geomagnetic sensor 9 and the battery pack 10 are encapsulated in the assembly shell 1 for use. During use, the vehicle will generate certain vibrations on the ground when it is running, and the vibrations will be transmitted to the movable plate 12 through the cover 2 and various components. The movable plate 12 will be squeezed by the vibration. The damping spring rod 11 is compressed, and the damper in the damping spring rod 11 can buffer and brake the vibration force by its own characteristics, thereby reducing the damage caused by the vibration force to the internal geomagnetic sensor 9 and the battery pack 10. At the same time, the damping spring rod 11 will use the telescopic spring to reset to prepare for the next vibration buffering. When the damping spring rod 11 pushes the movable plate 12 to reset, the soft pad 13 will preferentially contact the battery pack 10. The soft pad 13 can avoid secondary collision with the battery pack 10 when the movable plate 12 is reset, causing damage. When the geomagnetic induction device needs to be maintained, the shift block 8 is manually pressed down to make the shift block 8 drive the insertion block 7 to move out of the positioning groove 301. At this time, the cover 2 can be manually rotated in the opposite direction again to pull out the cover 2. The cover 2 can be completely separated from the assembly shell 1, and the geomagnetic sensor 9 and the battery pack 10 can be completely taken out, and the battery pack 10 can be taken to any position for replacement. This is the working principle of the geomagnetic induction device for parking that is easy to maintain.
