Description

Technical Field

[0001] The present invention relates to the technical field of GPS locators, and in particular to an intelligent logistics positioning terminal. Background Art

[0002] The smart logistics terminal is like a "smart brain" installed on the vehicle, and its core is the GPS locator.

When in use, connect the power cord to the normal power supply of the logistics vehicle, and then plug the connecting plug into the plug of the power cord to enable the GPS locator.

[0003] For example, the patent with the current announcement number CN216870816U discloses a GPS tracking locator, which belongs to the field of locator technology.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1 - Fig.11 , an intelligent logistics positioning terminal, including a locator consisting of a top shell 1, a bottom shell 2, a circuit board module 36 and a plug 19, the top shell 1 and the bottom shell 2 are connected to the outside with a mounting structure, the mounting structure includes an upper frame 3 and a lower frame 4, the outer wall of the upper frame 3 is fixedly connected with a fixing sleeve 10, the fixing sleeve 10 is internally threaded with a rotating rod 27, the top of the rotating rod 27 is fixedly connected with a dial plate 26, the outer wall of the dial plate 26 is rotatably connected with a resist plate 5, the outer wall of the lower frame 4 is fixedly connected with a T-shaped extrusion plate 6, the outer walls of both sides of the upper frame 3 are fixedly connected with buckles 15, and the two sides of the lower frame 4 are provided with bayonet holes 23 corresponding to the buckles 15, the outer wall of the dial plate 26 is fixedly connected with a plurality of annularly distributed teeth 7, the top outer side of the upper frame 3 is connected with a plug-in connector, the outer side of the plug 19 is connected with an anti-dropping component, the upper frame 3 is connected with a wiping component, and the bottom of the lower frame 4 is connected with a winding component.

[0020] The intelligent logistics positioning terminal of the present invention, when the positioner needs to be installed, the positioner is placed in the lower frame 4, so that the bottom shell 2 in the positioner is embedded in the lower frame 4, and then the upper frame 3 is covered on the outer side of the lower frame 4 outside the positioner, and the upper frame 3 and the lower frame 4 are fixed by the snap buckle 15 and the snap-on 23. Before this, the power cord of the positioner should be connected to the normal power of the logistics vehicle to ensure the power supply of the positioner, and then the male and female heads in the plug 19 are plugged into each other and snap-on with the anti-drop assembly to ensure the tight connection between the male and female heads in the plug 19. After all are connected, the entire device can be placed inside the front side of the cab of the logistics vehicle; At this time, by toggling the teeth 7, the dial plate 26 is driven to rotate, and the dial plate 26 drives the rotating rod 27 to rotate, so that it is connected with the internal thread of the fixed sleeve 10, so that the rotating rod 27 is extended outward in the fixed sleeve 10 through the threaded connection. Since the outer wall of the lower frame 4 is a fixed T-shaped extrusion plate 6, it is only necessary to rotate and adjust the dial plate 26 on the outer wall of the upper frame 3, so that the dial plate 26 drives the rotating rod 27 to adjust outward in the fixed sleeve 10 and increase the height. According to the spacing, the rotating rod 27 is extended, and then inserted into the internal cavity on the front side of the cab, so that the butt plate 5 and the T-shaped extrusion plate 6 are against the inner wall of the vehicle cavity on both sides. When the position is basically suitable, the dial plate 26 can be toggled again to drive the rotating rod 27 to continue to rotate. At this time, the butt plate 5 is squeezed on the inner wall of the vehicle cavity, and the dial plate 26 is rotatably connected with the butt plate 5. In this way, the butt plate 5 is prevented from being unable to rotate due to large friction, and it can also ensure that the rotating rod 27 gradually extends and tightens the butt plate 5, and fixes the positioner inside the vehicle cavity through friction. By using the annular abutment plate 5 and the T-shaped extrusion plate 6, the contact area can be increased, the force can be more evenly distributed, and the extrusion installation can be more firmly secured. Compared with the existing double-sided adhesive bonding method, the extrusion fixation is more secure, and damage to the locator caused by long-term bumps during vehicle driving can be avoided. At the same time, such a setting can avoid direct contact between the bottom surface of the locator and the inner wall of the cavity, which is beneficial to heat dissipation. The outer side of the paddle plate 26 is provided with an annularly distributed tooth 7, which is convenient for people to perform the paddle action.

[0021] The buckle 15 and the bayonet 23 in the above structure are existing mature technologies, so they will not be described in detail here.

[0022] As a preferred technical solution of the present invention, the connector includes a limit slide bar 38 and a limit plug rod 37. The outer side of the limit slide bar 38 is slidably connected to the limit plug rod 37. The top of the limit plug rod 37 is plugged into the cavity formed by two adjacent teeth 7. A spring 39 is sleeved on the outer side of the limit slide bar 38. A plurality of connecting ribs 21 are fixedly connected in the upper frame 3 and the lower frame 4. The bottom surface of the limit slide bar 38 is fixedly connected to the connecting rib 21. One end of the spring 39 abuts against the connecting rib 21, and the other end abuts against the bottom surface of the limit plug rod 37. A pressing plate 40 is fixedly connected to the outer side of the limit plug rod 37. The pressing plate 40 is rotatably connected to a rotating plate 41 at one end away from the limit plug rod 37. The top of the upper frame 3 is fixedly connected to an L-shaped block 18 that is clamped with the rotating plate 41. The connecting rib 21 abuts against the top shell 1 and the bottom shell 2 on both sides thereof. An elastic pad 22 is connected.

[0023] Specifically, when the paddle plate 26 needs to be moved, the rotating plate 41 can be rotated first to drive the rotating plate 41 and the end of the pressing plate 40 to rotate, and the rotating plate 41 can be pressed while rotating, so that the rotating plate 41 drives the pressing plate 40 to slide downward, and drives the limit rod 37 at the end of the pressing plate 40 to move downward, so that the limit rod 37 moves downward on the outside of the limit slide rod 38, and the spring 39 is compressed at this time. When the limit rod 37 is separated from the two adjacent teeth 7, the teeth 7 can be rotated to drive the paddle plate 26 to rotate; When the limit rod 37 is lowered, the rotating plate 41 can be engaged with the L-shaped block 18, so that the rotating plate 41 drives the pressing plate 40 and the limit rod 37 to always maintain a low position, which facilitates the rotation operation of the dial plate 26; When the abutment plate 5 is squeezed into place, the rotating plate 41 can be rotated out and separated from the L-shaped block 18, so that the limiting rod 37 rises under the action of the spring 39, so that the top of the limiting rod 37 is inserted between two adjacent teeth 7, so that the rotating rod 27 will not retreat in the fixing sleeve 10 during the long-term driving of the vehicle, making the fixing more secure; By using the arrangement of multiple connecting ribs 21 and elastic pads 22, the positioner is fixed between the upper frame 3 and the lower frame 4, which can absorb the vibration caused by the driving of the car to a certain extent, reduce the vibration of the positioner itself, and effectively improve the service life of the circuit board module 36 in the positioner; At the same time, the spacing between the connecting ribs 21 effectively ensures that the bottom surface of the positioner does not contact the inner wall of the installation cavity, further allowing heat to be dissipated more smoothly.

[0024] As a preferred technical solution of the present invention, the winding assembly includes an end plate 32, which is fixedly connected to the bottom surface of the lower frame 4. The outer wall of the end plate 32 is connected to two symmetrically arranged winding plates 12, and the two winding plates 12 are both inclined. The outer side of the end plate 32 is connected to a de-wire assembly.

[0025] Specifically, after installation, the power cord is still hanging outside, and the excess power cord can be wound around the outside of the two winding plates 12 outside the end plate 32. Since the two winding plates 12 are symmetrically inclined, they form a trumpet shape after unfolding, which can prevent the cable from falling.

[0026] By winding the redundant power lines through the two winding plates 12, the cables can be prevented from hanging down, and the cables can be arranged and stored to prevent the problem of mutual entanglement caused by vibration during the driving of the car.

[0027] As a preferred technical solution of the present invention, the de-wire assembly includes two L-shaped push plates 13, which are symmetrically arranged and respectively located on the outer walls of the end plate 32. The outer wall of the end plate 32 is fixedly connected to two mounting blocks 33, and the two ends of the two mounting blocks 33 are connected to a rotating shaft 34. The bottom of the winding plate 12 is sleeved on the outside of the rotating shaft 34, and the outside of the rotating shaft 34 is sleeved with a torsion spring 35. The L-shaped push plate 13 is slidably connected to the bottom surface of the lower frame 4, and the top surface of the upper frame 3 is slidably connected to a U-shaped rod 20. Both ends of the U-shaped rod 20 are fixedly connected to an L-shaped push rod 14, and the outer wall of the L-shaped push rod 14 is against the outer wall of the L-shaped push plate 13.

[0028] Specifically, when people need to take out the positioner, they rotate the dial plate 26 in the opposite direction, driving the rotating rod 27 to be threadedly connected with the fixing sleeve 10, so that the abutment plate 5 is separated from the inner wall of the installation cavity, and the positioner can be taken out of the installation cavity and repaired; At this time, the entire cable is stuck on the outside of the two winding plates 12. In order to facilitate the removal of the entire cable, the user can push the U-shaped rod 20 to drive the L-shaped push rods 14 at both ends to move, so that the outer wall of the L-shaped push rod 14 abuts against the L-shaped push plate 13, and drives the L-shaped push plate 13 to abut against the winding plate 12; Since the winding plate 12 is rotatably connected via the rotating shaft 34 and is restricted by the torsion spring 35, it always maintains an inclined state and always squeezes the L-shaped push plate 13; When the L-shaped push plate 13 moves, it squeezes the winding plate 12, and the winding plate 12 rotates. At this time, the two winding plates 12 rotate relative to each other, so that the ends are close to each other. At this time, the cable is loose. As the L-shaped push plate 13 continues to move, the cable located outside the two winding plates 12 is pushed out until it is separated from the two winding plates 12, completing the de-cable action; Through the cooperation of the rotating winding plate 12, the L-shaped push plate 13 and the L-shaped push rod 14, the entire cable can be detached when the positioner is taken out, which is convenient for the maintenance of the positioner.

[0029] As a preferred technical solution of the present invention, the anti-drop assembly includes two extension rods 16, the ends of the upper frame 3 and the lower frame 4 are fixedly connected with the extension rods 16, the ends of the extension rods 16 are fixedly connected with a clamping head 17, and a limiting groove for clamping the plug 19 is provided in the clamping head 17.

[0030] Specifically, after the positioner is embedded in the lower frame 4, the male and female heads of the plug 19 can be embedded in the limiting groove in the extension rod 16. Then, after the upper frame 3 and the lower frame 4 are merged, the limiting groove in another clamping head 17 will be clamped with the plug 19, thereby completing the limiting of the male and female heads in the plug 19, avoiding the problem of the plug 19 loosening due to the vibration of the car and avoiding poor contact.

[0031] As a preferred technical solution of the present invention, the wiping assembly includes a brush plate 11 and a moving rod 28. The brush plate 11 is located on the inner wall of the upper frame 3 and on the top of the signal light of the top shell 1. Moving grooves 24 are opened on the inner walls on both sides of the upper frame 3. The two ends of the moving rod 28 are respectively slidably connected to the two moving grooves 24, and the bottom surface of the brush plate 11 is against the top surface of the top shell 1.

[0032] Specifically, for the convenience of maintenance, when it is necessary to check whether the signal light of the locator is normal, the moving rod 28 can be pushed to drive the moving rod 28 to slide in the moving groove 24, and drive the brush plate 11 and the top shell 1 to wipe the signal light position. This setting can clean the dust adhering to the signal light, making it easier for the staff to identify the signal light and avoid unclear viewing of the signal light due to dust adhesion.

[0033] As a preferred technical solution of the present invention, two symmetrically arranged threaded rods 8 are fixedly connected to the top surface of the top shell 1. The two threaded rods 8 pass through the connecting ribs 21 on the upper frame 3 and are threadedly connected to threaded rings 9 at one end. The bottom surface of the threaded ring 9 is against the top surface of the connecting rib 21.

[0034] Specifically, the threaded rod 8 on the top of the top shell 1 can be passed through a connecting rib 21, and the threaded rod 8 can be fastened by a threaded ring 9. With this arrangement, when the upper frame 3 is separated from the lower frame 4, the top shell 1 and the bottom shell 2 can be directly separated, and the interior of the positioner can be inspected.

[0035] As a preferred technical solution of the present invention, two symmetrically arranged first slide grooves 25 are provided on the top surface of the upper frame 3 , and a first slider 30 is slidably connected in the first slide groove 25 , and the first slider 30 is fixedly connected to the L-shaped push rod 14 .

[0036] Specifically, when the L-shaped push rod 14 moves, it drives the first sliding block 30 to move in the first sliding groove 25. This arrangement ensures the stability of the L-shaped push rod 14 when moving.

[0037] As a preferred technical solution of the present invention, two symmetrically arranged second slide grooves 29 are provided on the bottom surface of the lower frame 4 , and a second slider 31 is slidably connected in the second slide groove 29 . The second slider 31 is fixedly connected to the L-shaped push plate 13 .

[0038] Specifically, when the L-shaped push plate 13 moves, it drives the second sliding block 31 to move in the second sliding groove 29 . This arrangement ensures the stability of the L-shaped push plate 13 when moving.

[0039] In the above structure, except for the torsion spring 35, other structures can be plastic structures, especially the threaded rod 8, the threaded ring 9, the rotating rod 27 and the fixed sleeve 10, to prevent the metal structure from interfering with the signal inside the locator. The torsion spring 35 is arranged on the bottom surface of the lower frame 4. First, the signal is generated upward. Secondly, a coating that prevents signal interference can be coated at this position or on the outside of the torsion spring 35, such as a ceramic-based composite coating, which will not affect the signal positioning function of the locator.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
