Description

Technical Field

[0001] This utility model relates to the field of electric buses, specifically to a front-charging structure for buses. Background Technology

[0002] Electric buses are passenger vehicles powered by electricity. Their core feature is the replacement of the internal combustion engine in traditional fuel-powered buses with an electric motor. Electrical energy is stored in an onboard battery pack and used to power the vehicle. These buses produce almost no exhaust emissions during operation, with carbon emissions only potentially occurring during power generation. Therefore, they are considered an important tool for the green transformation of urban public transportation. Compared to traditional fuel-powered buses, electric buses have a simpler power system structure. The energy conversion efficiency of electric motors typically reaches over 90%, far exceeding the 30%-40% efficiency of internal combustion engines. This means that with the same energy consumption, electric buses can travel a longer distance or consume less energy for the same distance.

[0003] The charging port of an electric bus is a key component connecting the external power source to the onboard battery, and its structural design must comprehensively consider safety, durability, and ease of operation. However, existing electric buses mainly locate their charging ports on the sides and rear. Side-mounted charging ports are often similar to those in passenger cars, using flip covers to conceal the exposed ports. However, this also obstructs the internal structure, making it difficult to inspect internal components. Rear-mounted charging ports require opening the rear panel of the bus, resulting in a cumbersome charging process and poor charging efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a front charging structure for buses, which aims to improve the problems of conventional electric buses where side charging makes it inconvenient to inspect internal components and the poor charging efficiency of rear charging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A front charging structure for a bus includes a front panel with a charging channel and a charging panel inside the charging channel. A frame is mounted on the rear side of the front panel, and a charging mechanism is fixed on the frame. The charging mechanism corresponds to the charging channel.

[0007] At least two opposing hinge connection components are hinged to the mounting frame. The free end of the hinge connection component is hinged to the charging panel. A drive component is fixed on the mounting frame. The drive end of the drive component is drivenly connected to one of the hinge connection components.

[0008] Furthermore, the hinge connection assembly includes an upper hinge plate, a lower hinge plate, and a first hinge arm. The upper hinge plate is fixed to the bottom surface of the mounting frame, and the lower hinge plate is fixed to the inner side of the charging panel.

[0009] The first hinge arm includes a first hinge segment and a second hinge segment that are hinged to each other. The free end of the first hinge segment is rotatably connected to one side of the upper hinge plate. The outer side of the second hinge segment is provided with a first bend. The free end of the second hinge segment is inclined upward and rotatably connected to one side of the lower hinge plate. The driving end of the driving assembly is hinged to the inner side of the second hinge segment.

[0010] Furthermore, the hinge connection assembly also includes a second hinge arm, which includes a third hinge segment and a fourth hinge segment that are hinged to each other.

[0011] The free end of the third hinge segment is rotatably connected to one side of the upper hinge plate. The third hinge segment and the second hinge segment are in contact with each other. The driving end of the driving assembly passes through the second hinge segment and is hinged to the third hinge segment.

[0012] The fourth hinge segment has a second bend on its outer side, and the free end of the fourth hinge segment is inclined upward and rotatably connected to the other side of the lower hinge plate.

[0013] Furthermore, one side of the upper hinge plate is the upper hinge side, and the free ends of the third hinge segment and the first hinge segment are rotatably connected to the front and rear ends of the upper hinge side, respectively.

[0014] The two upper hinge plates are arranged opposite each other, and the two upper hinge sides are located on the sides of the upper hinge plates that are far apart from each other.

[0015] Furthermore, the mounting frame includes an upper crossbar and a lower crossbar, which are horizontally fixed to the inner side of the front panel. Connecting arms are provided on both sides of the upper crossbar, and the bottom end of the connecting arm extends to both ends of the lower crossbar and is fixedly connected to the lower crossbar. A reinforcing crossbar is connected to the bottom of the connecting arm, and the reinforcing crossbar is fixedly connected to the inner side of the front panel.

[0016] Furthermore, the charging mechanism includes an upper charging frame, a lower charging frame, and charging components. The upper charging frame has outwardly extending mounting arms on both sides of its top. The free ends of the mounting arms are fixed to the inner side of the front panel and abut against the top of the upper crossbar.

[0017] The charging rack includes an installation part and a connecting part. The installation part is located inside the charging channel. The top of the connecting part is bent upwards towards the horizontal bar and is fixedly connected to the top surface of the upper horizontal bar. The bottom of the connecting part is bent downwards towards the horizontal bar and is fixedly connected to the bottom surface of the lower horizontal bar. The bottom end of the connecting part is connected to the installation part. A charging opening is provided on the connecting part.

The drive component drives the charging panel to open the charging channel to start charging or close the charging channel to stop charging, effectively improving charging efficiency. Furthermore, there is a gap between the charging mechanism and the charging channel, and the opening range of the charging channel is larger than that of the charging mechanism. When the charging panel is open, the internal charging mechanism can be directly inspected, improving maintenance efficiency. Attached Figure Description

[0044] Example

[0045] Please refer to Figure 1-7 As shown, this embodiment provides a front charging structure for a bus, including a front panel 1 with a charging channel 121. A charging panel 2 is disposed within the charging channel 121. A frame 3 is mounted on the rear side of the front panel 1, and a charging mechanism 4 is fixed on the mounting frame 3, corresponding to the charging channel 121. At least two opposing hinge connection components 5 are hinged to the mounting frame 3, with the free end of the hinge connection component 5 hinged to the charging panel 2. A drive component 6 is fixed on the mounting frame 3, and the drive end of the drive component 6 is drively connected to one of the hinge connection components 5.

[0046] The charging mechanism 4 is located inside the front of the vehicle and corresponds to the charging channel 121 on the front panel 1. The drive component 6 drives the charging panel 2 to open the charging channel 121 for charging or close the charging channel 121 to stop charging via the hinge connection component 5, effectively improving charging efficiency. Furthermore, there is a gap between the charging mechanism 4 and the charging channel 121, and the opening range of the charging channel 121 is larger than the range of the charging mechanism 4. This allows for direct inspection of the internal charging mechanism 4 when the charging panel 2 is open, improving inspection efficiency. Simultaneously, the charging mechanism 4 is located in the middle. In this embodiment, there are two hinge connection components 5: one set is the active structure, and the other set is the driven structure, ensuring that both sides of the charging panel 2 move synchronously, preventing the charging panel 2 from tilting during the flipping process and affecting the charging progress. Similarly, three or more hinge connection components 5 can also be provided. The hinge connection components 5, located on both sides of the charging mechanism 4, control the movement of the charging panel 2, effectively improving the stability and accuracy of the flipping opening and closing actions of the charging panel 2.

[0047] In this embodiment, the mounting frame 3 includes an upper crossbar 31 and a lower crossbar 32, which are horizontally fixed to the inner side of the front panel 1. Connecting arms 33 are provided on both sides of the upper crossbar 31, with the bottom ends of the connecting arms 33 extending to both ends of the lower crossbar 32 and fixedly connected to them. A reinforcing crossbar 34 is connected to the bottom of the connecting arms 33, and the reinforcing crossbar 34 is fixedly connected to the inner side of the front panel 1. The upper crossbar 31 and lower crossbar 32 are arranged vertically, effectively increasing the installation range of the mounting frame 3. The lower crossbar 32 connects the two connecting arms 33, enabling the connection between the upper crossbar 31 and the lower crossbar 32 and improving the overall structural strength of the mounting frame 3. The reinforcing crossbar 34 at the bottom of the connecting arms 33 further enhances the connection between the mounting frame 3 and the front panel 1, further improving the overall structural strength of the mounting frame 3 and the stability of the front panel 1 in the assembled state, thereby ensuring stable charging.

[0048] Furthermore, the top of the connecting arm 33 is hinged to the top surface of the upper crossbar 31. A maintenance channel 11 is provided on the front panel 1, within which a maintenance panel 12 is installed. A charging channel 121 is located on the maintenance panel 12. The lower crossbar 32, reinforcing crossbar 34, hinge connection assembly 5, and drive assembly 6 are all located on the inner side of the maintenance panel 12. The connecting arm 33 enables the maintenance panel 12 to be flipped, effectively increasing the opening area for the internal charging mechanism 4 and internal components, further improving the ease of maintenance for the internal components.

[0049] Please refer to Figure 4 and Figure 7 As shown, specifically, the hinge connection assembly 5 includes an upper hinge plate 51, a lower hinge plate 52, and a first hinge arm 53. The upper hinge plate 51 is fixed to the bottom surface of the mounting frame 3. In this embodiment, the upper hinge plate 51 is fixed to the bottom surface of the lower crossbar 32; the lower hinge plate 52 is fixed to the inner side of the charging panel 2. Further, a pad 21 is fixed to the inner side of the charging panel 2, and the lower hinge plate 52 is fixed to both ends of the pad 21. In this embodiment, both the lower hinge plate 52 and the upper hinge plate 51 are fixed to the pad 21 and the lower crossbar 32 by bolts. The pad 21 is used to install the lower hinge plate 52, avoiding punching holes in the charging panel 2 and affecting the flatness of the charging panel 2. At the same time, when the lower hinge plate 52 is subjected to force, it transmits the force to the pad 21, and the pad 21 transmits the pushing or pulling force to the charging panel 2, effectively increasing the force transmission area and improving the stability of the charging panel 2's operation.

[0050] The first hinge arm 53 includes a first hinge segment 531 and a second hinge segment 532 that are hinged to each other. The free end of the first hinge segment 531 is rotatably connected to one side of the upper hinge plate 51. The outer side of the second hinge segment 532 is provided with a first bending portion 5321. The free end of the second hinge segment 532 is inclined upward and rotatably connected to one side of the lower hinge plate 52. The driving end of the driving assembly 6 is hinged to the inner side of the second hinge segment 532. In this embodiment, the driving assembly 6 is a driving cylinder. The driving end of the driving cylinder is hinged to the inner side of the second hinge segment 532. The movement of the charging panel 2 is driven by driving the position of the second hinge segment 532. Similarly, other driving structures can also be used. The outer side of the second hinge segment 532 is provided with an upwardly extending first bending portion 5321, so that when the charging panel 2 is in the open state, the second hinge segment 532 can drive the charging panel 2 to move more, fully exposing the charging channel 121 and improving the convenience of charging. In this embodiment, the angle between the charging panel 2 and the front panel 1 when the charging panel 2 is open is 120°, so that the charging panel 2 makes room for the top structure of the charging gun 7 to the maximum extent, avoiding positional interference with the charging gun 7 and affecting the charging process.

[0051] Furthermore, the hinge connection assembly 5 also includes a second hinge arm 54, which includes a third hinge segment 541 and a fourth hinge segment 542 that are hinged to each other. The free end of the third hinge segment 541 is rotatably connected to one side of the upper hinge plate 51; the third hinge segment 541 and the second hinge segment 532 are in contact with each other, and the driving end of the drive assembly 6 passes through the second hinge segment 532 and is hinged to the third hinge segment 541. The outer side of the fourth hinge segment 542 is provided with a second bend 5421, and the free end of the fourth hinge segment 542 is inclined upward and rotatably connected to the other side of the lower hinge plate 52. In this embodiment, the driving end of the driving cylinder synchronously drives the second hinge segment 532 and the third hinge segment 541 to form an "X"-shaped hinge structure, so that the second hinge segment 532 and the fourth hinge segment 542 can synchronously provide driving force to the lower hinge plate 52; at the same time, the ends of the second hinge segment 532 and the ends of the fourth hinge segment 542 are rotatably connected to the two sides of the lower hinge plate 52 respectively, effectively increasing the range of the force exerted by the hinge connection assembly 5 on the lower hinge plate 52, and further improving the movement stability of the charging panel 2.

[0052] Please refer to Figure 3-5As shown, in this embodiment, one side of the upper hinge plate 51 is the upper hinge side 511, and the free ends of the third hinge segment 541 and the first hinge segment 531 are rotatably connected to the front and rear ends of the upper hinge side 511, respectively. The third hinge segment 541 and the first hinge segment 531 are connected to the same side of the upper hinge plate 51, making the driving force output by the driving component 6 more concentrated and improving the driving effect on the charging panel 2. The two upper hinge plates 51 are arranged opposite to each other, and the two upper hinge sides 511 are located on the sides of the upper hinge plates 51 that are far apart from each other. That is, the upper hinge sides 511 are located on the outer side of the upper hinge plates 51, making the force on the charging panel 2 symmetrically distributed, further improving the accuracy of the movement of the charging panel 2.

[0053] Please refer to Figure 3 As shown, in this embodiment, a lock body 22 is fixed on the charging panel 2, and a baffle 23 is rotatably connected to the lock body 22. The baffle 23 extends downward to the inner side of the front panel 1. The lock body 22 drives the baffle 23 to rotate. Before charging, the lock body 22 is driven to rotate, thereby causing the baffle 23 to rotate from the inner side of the front panel 1 to the charging channel 121, releasing the restriction on the charging panel 2. The drive assembly 6 drives the charging panel 2 to flip and open the charging channel 121. After charging is completed, the drive assembly 6 drives the charging panel 2 to flip and reset, closing the charging channel 121. The lock body 22 is driven to rotate, causing the baffle 23 to move from the inner side of the charging channel 121 to the inner side of the front panel 1, limiting the charging panel 2 and preventing the charging panel 2 from opening while driving, which would expose the charging panel and make it susceptible to damage.

[0054] Please refer to Figure 2-5 As shown, specifically, the charging mechanism 4 includes a charging upper frame 41, a charging lower frame 42, and a charging component 43. The charging upper frame 41 has outwardly extending mounting arms 411 on both sides of its top. The free ends of the mounting arms 411 are fixedly attached to the inner side of the front panel 1 and abut against the top of the upper crossbar 31. The mounting arms 411 extend to both sides, forming a figure-eight connection structure and are fixedly connected to the front panel 1. Simultaneously, the top of the upper crossbar 31 supports the mounting arms 411, effectively improving the installation stability of the charging upper frame 41.

[0055] The charging lower bracket 42 includes an installation part 421 and a connecting part 422. The installation part 421 is located inside the charging channel 121. The top of the connecting part 422 is bent upward towards the upper crossbar 31 and is fixedly connected to the top surface of the upper crossbar 31. The bottom of the connecting part 422 is bent downward towards the lower crossbar 32 and is fixedly connected to the bottom surface of the lower crossbar 32. The bottom end of the connecting part 422 is connected to the installation part 421. A charging opening 4221 is formed in the connecting part 422. The charging component 43 is fixed on the charging upper bracket 41 and the installation part 421. The installation part 421 and the charging upper bracket 41 carry the charging component 43. The front end of the connecting part 422 to the installation part 421 fixes the installation part 421 and forms a charging opening 4221 for the charging gun 7 to pass through and be plugged into the charging component 43. The upper side of the connecting part 422 forms a "C"-shaped connection structure that covers and is fixed on the upper crossbar 31 and the lower crossbar 32, effectively improving the structural strength of the connecting part 422, thereby improving the fixing effect on the installation part 421.

[0056] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
