Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, and particularly relates to a circuit connection device for a van body. Background Art

[0002] A variety of electrical appliances are arranged inside a detachable carriage, so it is necessary to use wires to connect the power supply on the vehicle chassis with the power supply or load of the carriage power supply; however, since the carriage is required to be detachable, wires cannot be directly used to connect the vehicle chassis power supply and the carriage power supply, because it will affect the loading and unloading of the carriage. Therefore, our company previously designed a conductive device specifically for detachable carriages, with the patent document number CN220830166U and the name of a conductive device for connecting a carriage and a vehicle chassis; when using this solution to complete the circuit conduction, two insulating sleeves are required to complete nesting. When the driver operates incorrectly, an error may occur. This error may cause the two insulating sleeves to complete nesting, thus requiring readjusting the position where the carriage drops, and even possibly damaging the conductive device. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies existing in the prior art and provide a circuit connection device for a van body. Through the first contact point and the second contact point respectively arranged on the first conduction module and the second conduction module, only surface contact between the two contact points is required to complete the circuit conduction, reducing the difficulty of circuit conduction and preventing component damage caused by incorrect operation.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A circuit connection device for a van body includes a first conduction module and a second conduction module which are arranged corresponding to each other up and down; the first conduction module is provided with a pressure screw nut, and the second conduction module is provided with a pressure screw nut; the first conduction module further includes a first mounting seat fixedly connected to the carriage or the vehicle frame and a first conductive column capable of relatively sliding inside the first mounting seat; a first contact point protruding in the same vertical direction as the first conductive column is arranged inside the first mounting seat; the second conduction module further includes a second mounting seat fixedly connected to the vehicle frame or the carriage and a second conductive column capable of relatively sliding inside the second mounting seat; a second contact point protruding in the same vertical direction as the second conductive column is arranged inside the second mounting seat; the first conductive column is connected with a first conductive column spring for resetting, and the second conductive column is connected with a second conductive column spring for resetting; when the first contact point contacts the first conductive column, the first conduction module realizes a closed circuit; when the second contact point contacts the second conductive column, the second conduction module realizes a closed circuit, and at the same time, the first conduction module and the second conduction module are conducted.

[0005] Further, the first mounting seat is provided with a counterbore, and a first contact spring and a first conductive bolt are arranged at the bottom of the counterbore. One end of the first contact spring is connected to the first contact, and the other end is connected to the first conductive bolt. When the first contact spring is in a relaxed state, the end of the first contact protrudes into the counterbore. One end of the first conductive bolt located outside the first mounting seat is connected with a first wire pressing nut.

[0006] Further, the second mounting seat is provided with a counterbore, and a second contact spring and a second conductive bolt are arranged at the bottom of the counterbore. One end of the second contact spring is connected to the second contact, and the other end is connected to the second conductive bolt. When the second contact spring is in a relaxed state, the end of the second contact protrudes into the counterbore. One end of the second conductive bolt located outside the second mounting seat is connected with a second wire pressing nut.

[0007] Further, the second conductive column has the same shape as the first conductive column, and both include a T-shaped body and a necking convex platform. An insulating cover is wrapped around the side of the second conductive column, and an insulating cover is wrapped around the side of the first conductive column.

[0008] Further, a second conductive plate is sleeved on the side of the necking convex platform of the second conductive column, and the top of the insulating cover does not exceed the top of the corresponding necking convex platform. A first conductive plate is sleeved on the side of the necking convex platform of the first conductive column.

[0009] Further, the upper surface of the insulating cover is a convex arc surface, and the lower surface of the insulating cover is a concave arc surface. The lower surface of the insulating cover is a concave arc surface that can wrap the upper surface of the insulating cover.

[0010] Further, a first conductive plate is wrapped around the side of the necking convex platform of the first conductive column, and a second conductive plate is wrapped around the side of the necking convex platform of the second conductive column. The insulating cover wraps the outer side of the first conductive plate, and the insulating cover wraps the outer side of the second conductive plate.

[0011] Further, a vehicle frame mounting plate is fixed to the second mounting seat, and the vehicle frame mounting plate is fixedly connected to the vehicle frame. A carriage mounting plate is fixedly arranged on the first mounting seat, and the carriage mounting plate is fixedly connected to the carriage.

[0012] Further, the first mounting seat has the same shape as the second mounting seat. The first mounting seat is threadedly connected to a first mounting nut, and the second mounting seat is threadedly connected to a second mounting nut.

[0013] Further, the first conduction module and the second conduction module can be swapped with each other.

[0014] The beneficial effects of the present utility model are as follows: By respectively arranging the first contact and the second contact on the first conduction module and the second conduction module, only by making the surfaces of the two contacts contact with the conductive posts respectively can the circuit conduction be completed. The contact has a relatively large allowable error range, reducing the difficulty of circuit conduction, preventing component damage caused by operation errors, and at the same time reducing the operation difficulty of the driver; even if the two contacts are partially in contact, the circuit conduction can still be achieved; the setting of the spring reduces the collision during contact and prevents the components from being damaged by impact.

[0020] The present utility model will be further explained and described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment:

[0022] As Figures 1-4As shown in the figure, a circuit connection device for a van includes a first conduction module 23 provided at the bottom of the carriage 27 and a second conduction module 24 provided at the top of the vehicle frame 25. When the carriage 27 is placed on the vehicle frame 25, the first conduction module 23 and the second conduction module 24 are vertically corresponding. The first conduction module 23 is connected to the carriage 27, and the second conduction module 24 is connected to the vehicle frame. The carriage 27 is provided with a carriage power supply 26. The first conduction module 23 includes a first pressure nut 5 connected to the carriage power supply 26 through a wire. The second conduction module 24 includes a second pressure nut 16 electrically connected to a power transmission component on the vehicle frame 25. The power transmission component can be a power supply or a generator. The second conduction module 24 further includes a second mounting seat 20 fixedly connected to the vehicle frame 25 and a second conductive column 12 capable of sliding relative to the inside of the second mounting seat 20. A second contact 19 protruding to the same vertical direction as the second conductive column 12 is provided inside the second mounting seat 20. The first conduction module 23 further includes a first mounting seat 1 fixedly connected to the carriage 27 and a first conductive column 8 capable of sliding relative to the inside of the first mounting seat 1. A first contact 2 protruding to the same vertical direction as the first contact 2 is provided inside the first mounting seat 1. The first conductive column 8 is energized with the first contact 2. The first conductive column 8 is connected to a first conductive column spring 6 for resetting, and the second conductive column 12 is connected to a second conductive column spring 15 for resetting.

[0023] When the first contact 2 contacts the first conductive column 8, the first conduction module 23 forms a closed circuit. When the second contact 19 contacts the second conductive column 12, the second conduction module 24 forms a closed circuit, and at the same time, the first conduction module 23 and the second conduction module 24 are conducted.

[0024] A vehicle frame mounting plate 21 is fixed to the second mounting seat 20, and the vehicle frame mounting plate 21 is fixedly connected to the vehicle frame 25 through bolts. A carriage mounting plate 22 is fixed to the first mounting seat 1, and the carriage mounting plate 22 is fixedly connected to the carriage 27 through bolts.

[0025] The first mounting nut 7 and the second mounting nut 14 are made of nylon material.

[0026] A counterbore is formed in the middle of the second mounting seat 20 from top to bottom. The bottom of the counterbore is connected to the second conductive column spring 15, and the top of the second conductive column spring 15 is connected to the second conductive column 12. The second conductive column 12 is slidably connected to the inner wall of the counterbore. A second contact spring 18 and a second conductive bolt 17 are provided at the bottom of the counterbore. One end of the second contact spring 18 is connected to the second contact 19, and the other end is connected to the second conductive bolt 17. When the second contact spring 18 is in a relaxed state, the end of the second contact 19 protrudes into the counterbore. The end of the second conductive bolt 17 located outside the second mounting seat 20 is connected to a second pressure nut 16.

[0027] In the middle of the first mounting base 1, a counterbore is formed from bottom to top. The bottom of the counterbore is connected to the first conductive post spring 6, and the first conductive post spring 6 is connected to the first conductive post 8. At the bottom of the counterbore, a first contact spring 3 and a first conductive bolt 4 are provided. One end of the first contact spring 3 is connected to the first contact 2, and the other end is connected to the first conductive bolt 4. When the first contact spring 3 is in the relaxed state, the end of the first contact 2 protrudes into the counterbore. One end of the first conductive bolt 4 located outside the first mounting base 1 is connected to a first pressing nut 5.

[0028] The first mounting base 1 and the second mounting base 20 have the same shape. The first mounting base 1 is threadedly connected to the first mounting nut 7, and the second mounting base 20 is threadedly connected to the second mounting nut 14.

[0029] The second conductive post 12 and the first conductive post 8 have the same shape. Both of them include a T-shaped body and a necked-down boss. The diameter of the boss is smaller than the diameter of the vertical section of the T-shaped body, so it is called a necked-down boss. The two necked-down bosses are arranged opposite to each other and are close to each other. An insulating cover convex 13 is wrapped around the side of the second conductive post 12, and an insulating cover concave 9 is wrapped around the side of the first conductive post 8.

[0030] The side of the necked-down boss of the first conductive post 8 is wrapped with a first conductive plate 10, and the side of the necked-down boss of the second conductive post 12 is wrapped with a second conductive plate 11. The insulating cover concave 9 wraps the outer side surface of the first conductive plate 10, and the insulating cover convex 13 wraps the outer side surface of the first conductive plate 10.

[0031] The distance from the first conductive post 8 to the outside of the nut 7 connected to the first mounting base 1 is less than the length of the T-shaped body of the first conductive post 1. The distance from the second conductive post 12 to the outside of the nut 14 connected to the second mounting base 20 is less than the length of the T-shaped body of the second conductive post 12. Such a setting ensures that after the conductive post contacts and conducts electricity with the conductive block, the conductive post can continue to move towards the bottom of the groove. The end of the conductive block protrudes. When the conductive block contacts the conductive post, it will shrink a part. The conductive block and the fixed seat are connected by an elastic module such as a spring, so as to ensure close contact with the conductive post for power-on and not affect the movement of the conductive post.

[0032] The side of the necked-down boss of the second conductive post 12 is sleeved with a second conductive plate 11, and the top of the insulating cover convex 13 does not exceed the top of the corresponding necked-down boss. The side of the necked-down boss of the first conductive post 8 is sleeved with a first conductive plate 10.

[0033] The upper surface of the insulating cover convex 13 is a convex arc surface, the lower surface of the insulating cover concave 9 is a concave arc surface, and the lower surface of the insulating cover concave 9 is a concave arc surface that can wrap the upper surface of the insulating cover convex 13.

[0034] The side of the necking boss of the first conductive post 8 wraps the first conductive plate 10, and the side of the necking boss of the second conductive post 12 wraps the second conductive plate 11; the insulating cover recess 9 wraps the outer side surface of the first conductive plate 10, and the insulating cover protrusion 13 wraps the outer side surface of the second conductive plate 11.

[0035] The edge of the upper surface of the insulating cover recess 13 protrudes upward, and the middle part is recessed for accommodating the second conductive plate 11 and the necking boss; the insulating cover recess 9 is recessed for accommodating the necking boss and the first conductive plate 10. When the carriage 27 falls on the vehicle frame 25, the recessed part is also used for accommodating the insulating cover recess 13.

[0036] The setting of the first contact spring 3 and the second contact spring 18 facilitates the control of the on-off of the circuit.

[0037] When the carriage 27 falls on the vehicle frame 25, the first conductive plate 10 contacts the second conductive plate 11 and pushes the first conductive post 8 and the second conductive post 12 to generate a displacement and make contact, so that the first conductive plate 10, the first conductive post 8, the first contact 2, the first contact spring 3, the first conductive bolt 4, and the first pressure nut 5 form a circuit; the second conductive plate 11, the second conductive post 12, the second contact 19, the second contact spring 18, the second conductive bolt 17, and the second pressure nut 16 form a circuit; the first conductive bolt 4 and the second conductive bolt 16 form a circuit; when the carriage 27 is separated from the vehicle frame 25, the first conductive post spring 6 and the second conductive post spring 15 respectively push the first conductive post 8 and the second conductive post 12 to generate a displacement, so that the first conductive post 8 is disconnected from the first contact 2 to form an open circuit; the second conductive post 12 is disconnected from the second contact 19 to form an open circuit; thus, the exposed first conductive plate 10 and the second conductive plate 11 are both non-electrified.

[0038] In this embodiment, by respectively arranging the first contact and the second contact in the first conduction module and the second conduction module, only two contact surfaces need to be in contact to complete the circuit conduction. The contact has a large allowable error range, reducing the difficulty of circuit conduction, preventing component damage caused by operation errors, and at the same time reducing the operation difficulty of the driver; even if the two contacts are partially in contact, the circuit can still be conducted; the setting of the spring reduces the collision during contact and prevents the components from being damaged by impact.

[0039] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
