Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle chargers, in particular to an electric vehicle charger fixing device. Background Art

[0002] The placement of traditional electric vehicle chargers is uncertain. Some are placed in the trunk, seat tub, and front storage box, which is rather random and may not even be carried with the vehicle. When the vehicle is bumpy, the charger may collide with the frame and be easily damaged. Moreover, since some electric vehicle seat tubs are small, they can only be placed in the front and rear storage boxes, where there is a risk of contact with water, posing certain safety hazards.

[0003] In addition, electric vehicles are generally charged in public parking lots. Traditional external electric vehicle chargers are at risk of being stolen during charging, causing property loss. Moreover, electric vehicle batteries are generally located at the bottom of the seat barrel, and many criminals will pry open the seat cushion to take out the battery inside.

[0004] To this end, we propose an electric vehicle charger fixing device. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides an electric vehicle charger fixing device, which is convenient for carrying the charger component on the vehicle. In addition, the flexible connection method can also buffer the impact caused by bumps.

[0006] The technical solution adopted by the utility model is as follows:

[0030] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0031] like Figure 1-Figure 5 As shown, the present embodiment discloses a charger fixing device for an electric vehicle, comprising a frame 100, a seat barrel 300, a seat cushion assembly 200, a charger assembly 400 and a mounting frame 500, wherein the charger assembly 400 is directly connected to the battery of the electric vehicle, and the charger assembly 400 is vertically attached to the inner wall of the seat barrel 300 in an elastic connection manner through the mounting frame 500, which facilitates carrying the charger assembly 400 on the vehicle. In addition, the elastic connection method can also buffer the impact force caused by bumps, and further protect the charger assembly 400. Moreover, since the charger assembly 400 is fixed, the battery can be charged by only passing the wiring harness 4011 through the seat barrel 300 during subsequent charging, thereby avoiding loss of the charger assembly 400.

[0032] A frame 100, in which a seat bucket 300 is disposed, and a flippable seat cushion assembly 200 is disposed on the frame 100, and the seat cushion assembly 200 cooperates with the seat bucket 300 to form a relatively sealed space;

[0033] The charger assembly 400 is vertically attached to the inner wall of the seat bucket 300 through the mounting frame 500. The vertical attachment can reduce collisions, because the bumping direction of electric vehicles is generally vertical, and the vertical attachment method can avoid collisions;

[0034] In this embodiment, Figure 1-Figure 4 As shown, the mounting frame 500 is in an L-shaped structure, wherein the horizontal section thereof is fixed on the vehicle frame 100 together with the seat bucket 300, and the vertical section thereof is in contact with the side wall of the seat bucket 300, and the lower end of the vertical section of the mounting frame 500 is connected with an outward-turned connector 502, which is plugged into a slot provided on the seat bucket 300 to achieve buffering positioning. The mounting frame 500 is a sheet metal part, and since only the upper end is fixed and the lower end is plug-in, it has a certain amount of elasticity when the vehicle is bumpy, and can buffer the impact force of the collision, and cooperate with the vertical direction matching design to protect the charger from damage to the greatest extent.

[0035] In this embodiment, the charger assembly 400 includes a charging module 401 and a cover shell 402 covering the charging module 401, the cover shell 402 includes a front cover and a rear cover, the cover shell 402 is a plastic part, and a plurality of ventilation holes are arranged on the cover shell 402 to meet the heat dissipation of the charging module 401 during charging, the charging module 401 passes through the rear cover and is connected to the mounting frame 500 through a plurality of tamper-proof connectors 4012, and the front cover is connected to the rear cover through a plurality of locking members 4021 to form a package for the charging module 401.

[0036] In this embodiment, the locking member 4021 includes screws, buckles, magnets, interference fit connections, etc.

[0037] In this embodiment, the horizontal section of the mounting frame 500 is connected to the upper end surface of the seat bucket 300 via a second tamper-proof connector 501 .

[0038] In this embodiment, the connectors in the tamper-proof connector include screws, snaps, magnets, interference fit connections, etc. The tamper-proof structure shows special treatment of the connection methods of each connector. For example, the bolt groove on the screw head is changed to a special-shaped structure, the opening position of the snap structure is hidden, and the positions of the magnetic and interference fit connections are hidden, thereby achieving an anti-tampering function and preventing theft.

[0039] Generally, the battery of an electric vehicle is located at the bottom wall of the electric vehicle seat barrel 300. The charging module 401 can be fixed by using an anti-tampering connector 4012. In addition, since the mounting frame 500 is connected to the seat barrel 300 through an anti-tampering connector 501, disassembly can also be avoided, thereby preventing the charger from being stolen.

[0040] In this embodiment, Figure 2 As shown, the charging module 401 is provided with a wiring harness 4011, which passes through a through hole opened on the cover shell 402, and a recess a for extending the wiring harness 4011 is opened on the upper end side of the seat bucket 300. This allows charging to be performed even when the seat cushion assembly 200 is closed, thereby preventing the wiring harness 4011 from being pinched. Most importantly, the charging module 401 can be charged in the seat bucket 300 to prevent theft.

[0041] In this embodiment, the mounting frame 500 is provided with a connection protrusion 503 matching the tamper-proof connector 4012, and the connection protrusion 503 has a flange + thread. The connection protrusion 503 is used to assemble the tamper-proof connector 4012, and on the other hand, a buffer pad can be connected to the connection protrusion 503 to reduce the impact of the collision.

[0042] The utility model places the charger in the charger rear cover, installs it on the sheet metal through the connecting piece, covers the charger front cover, and locks it with the connecting piece. Then the charger, the charger rear cover, the sheet metal and the charger front cover are installed on the frame, placed in the seat bucket 300, and covered with the seat cushion assembly 200.

[0043] In this embodiment, the specific installation method is as follows:

[0044] like Figure 4 As shown, the charger assembly 400 and the cover 402 are fixed to the mounting bracket 500 via four tamper-proof connectors 4012 .

[0045] like Figure 4 As shown, use two locking pieces 4021 to install the front cover on the rear cover.

[0046] like Figure 2 As shown, two tamper-proof connectors 501 are used to lock the seat barrel 300 to the frame 100, and the lower side of the mounting frame 500 is inserted into the plastic structure of the seat barrel 300 through the connector 502, which effectively controls the shaking of the mechanism caused by riding.

[0047] After the two tamper-proof connectors 501 are installed, the seat cushion assembly 200 is buckled together to effectively achieve a waterproof and dustproof effect.

[0048] 1. The charger assembly 400 and the mounting frame 500 are locked together with the seat bucket 300 on the frame 100 as a component, and the charger assembly 400 is prevented from contacting with foreign objects under the condition that the heat dissipation of the charger is fully met (there are ventilation and heat dissipation holes on the front cover 402), thereby effectively protecting the charger assembly 400 from damage.

[0049] 2. The charging module 401 is fixed to the mounting frame 500 by means of an anti-tampering connector 4012, and the mounting frame 500 is also locked to the vehicle frame 100 by means of an anti-tampering connector 501, so it cannot be easily disassembled and can meet the function of being carried in the vehicle.

[0050] The utility model changes the idea. On the premise of fully meeting the heat dissipation of the charger, the charger assembly 400 is fixed in the cover 402, and then the charger assembly 400 and the mounting frame 500 are installed on the frame 100 and placed in the seat bucket 300, so that it can be carried with the vehicle, the buffering effect is improved, the charger can be protected from damage and water, and the safety performance is improved.

[0051] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
