Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a modular interface multi-functional expansion dock for electric buses. Background Technology

[0002] Electric buses are more electrified than fuel-powered buses. To improve passenger comfort, electric buses use docking stations to add universal interfaces that meet passengers' needs for charging electronic devices.

[0003] The existing electric bus expansion docks have a fixed number of interfaces and a single type, which can only meet the needs of a small number of general-purpose devices. Expansion requires the entire expansion dock to be replaced, which is costly. In addition, the expansion docks lack wiring fixation and protection structures. Under the vibration environment of electric buses, the wiring and interfaces are prone to loosening and falling off, resulting in data transmission interruption and frequent charging failures. Summary of the Invention

[0004] This utility model provides a modular interface multi-functional expansion dock for electric buses. The main expansion module increases the number of expansion interfaces through the secondary expansion frame. When new interfaces are needed, there is no need to replace the entire expansion dock. Only the corresponding secondary expansion frame needs to be installed. The line protection bracket and the upper fixing frame clamp the lines connected to the expansion interfaces to achieve line positioning operation. This avoids the expansion interfaces and lines from loosening due to vibration during electric bus operation, which could lead to data interruption or charging failure.

[0005] This utility model provides a modular interface multi-functional expansion dock for electric buses, specifically including a main expansion module, a secondary expansion frame, and a line protection bracket. The secondary expansion frame is provided on both sides of the main expansion module, and line protection brackets are arranged in an array at intervals on the front sides of both the main expansion module and the secondary expansion frame. A lower spherical slide column is fixedly connected to the bottom of the main expansion module, and the lower spherical slide column is slidably connected to the lower connecting base. The lower connecting base is connected and fixed to the inside of the bus by adhesive or screws. An expansion interface is arranged in an array at intervals on the front of the main expansion module. The expansion interface includes Ethernet interface, USB-C interface, etc. The main expansion module has an outer annular slide groove on the outside of the expansion interface. Side support rods are rotatably connected to both sides of the main expansion module, and side limit plugs are slidably connected to both sides of the main expansion module.

[0006] Furthermore, the side limiting plug and the side support rod head end groove are slidably connected, the front part of the secondary expansion frame is provided with an expansion interface at intervals, and the secondary expansion frame has an outer annular sliding groove on the outside of the expansion interface.

[0007] Furthermore, the expansion interfaces on both sides of the main expansion module and the front interface of the sub-expansion frame are slidably connected, and the bottom of the sub-expansion frame and the top of the side support rod slide together.

[0008] Furthermore, a lower positioning block is slidably connected to the middle of the secondary expansion frame, and a lower connecting slide is protruding from the bottom of the secondary expansion frame.

[0009] Furthermore, the lower positioning plug and the middle groove of the side support rod are slidably connected, the lower connecting slide bar and the top groove of the side support rod are slidably connected, and the sub-expansion frame is linked with the main expansion module through the interface, supporting plug and play. When new interface requirements are needed, there is no need to replace the entire expansion dock, only the corresponding sub-expansion frame needs to be installed.

[0010] Furthermore, the upper part of the line protection bracket is slidably connected to an upper fixed frame, and a middle connecting spring is fixedly connected between the line protection bracket and the upper fixed frame.

[0011] Furthermore, the line protection bracket and the outer annular groove are slidably connected. The line protection bracket moves in a circular motion along the outer annular groove. The position of the line protection bracket is adjusted to support the line in different bending directions. The expansion interface is located between the upper fixed frame and the line protection bracket. The line protection bracket and the upper fixed frame achieve radial clamping of the line under the action of the connecting spring.

[0012] This utility model provides a modular interface multi-functional expansion dock for electric buses, which has the following advantages: The main expansion module increases the number of expansion interfaces through the secondary expansion rack. When new interfaces are needed, there is no need to replace the entire expansion dock; only the corresponding secondary expansion rack needs to be installed. Interface combinations can be flexibly configured according to operational needs, reducing the cost of expanding a single interface.

[0013] The line protection bracket and upper fixing frame clamp the line connected to the expansion interface to achieve line positioning operation, avoiding the expansion interface and line loosening caused by vibration during the operation of the electric bus, which could lead to data interruption and charging failure. The side support rod supports the secondary expansion frame, reducing the possibility of the side support rod loosening the secondary expansion frame due to vibration during the operation of the electric bus, which could lead to data interruption and charging failure, thus ensuring reliability.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a modular interface multi-functional expansion dock for electric buses, including a main expansion module 1, a secondary expansion frame 2, and a line protection bracket 3. The bottom of the main expansion module 1 is fixedly connected to a lower spherical slide column 101, which is slidably connected to a lower connecting base 102. The lower connecting base 102 is connected and fixed to the interior of the bus by adhesive or screws. The front of the main expansion module 1 is provided with an array of expansion interfaces 103, including Ethernet interfaces and USB-C interfaces. The main expansion module 1 has an outer annular groove 104 on the outer side of the expansion interfaces 103. Side support rods 105 are rotatably connected to both sides of the main expansion module 1, and side limiting blocks 106 are slidably connected to both sides of the main expansion module 1. The side limiting blocks 106 and the grooves at the ends of the side support rods 105 are slidably inserted into each other. The front of the secondary expansion frame 2 is also provided with an array of expansion interfaces 103. 03. The secondary expansion frame 2 has an outer annular groove 104 on the outside of the expansion interface 103. The expansion interfaces 103 on both sides of the main expansion module 1 and the first end interface of the secondary expansion frame 2 are slidably connected. The bottom of the secondary expansion frame 2 and the top of the side support rod 105 slide against each other. The secondary expansion frame 2 is provided on both sides of the main expansion module 1. The middle of the secondary expansion frame 2 is slidably connected to the lower positioning block 201. The bottom of the secondary expansion frame 2 is provided with a lower connecting slide bar 202. The front sides of the main expansion module 1 and the secondary expansion frame 2 are provided with line protection brackets 3 at intervals. The upper part of the line protection bracket 3 is slidably connected to the upper fixed frame 301. The line protection bracket 3 and the upper fixed frame 301 form a C-shaped structure. The line protection bracket 3 and the upper fixed frame 301 have an opening on one side to facilitate the entry of the line and the opening of the middle connecting spring 302. The middle connecting spring 302 is fixedly connected between the line protection bracket 3 and the upper fixed frame 301.

[0019] In this embodiment, the lower positioning plug 201 and the middle groove of the side support rod 105 are slidably connected, the lower connecting slide bar 202 and the top groove of the side support rod 105 are slidably connected, and the sub-extension frame 2 is linked with the main expansion module 1 through the interface, supporting plug and play. When a new interface is required, there is no need to replace the entire expansion dock, only the corresponding sub-extension frame 2 needs to be installed, reducing the cost of single interface expansion.

[0020] In this embodiment, the line protection bracket 3 and the outer annular groove 104 are slidably connected. The line protection bracket 3 moves in a circular motion along the outer annular groove 104. The position of the line protection bracket 3 is adjusted to support the line in different bending directions. The expansion interface 103 is located between the upper fixed frame 301 and the line protection bracket 3. The line protection bracket 3 and the upper fixed frame 301 are radially clamped under the action of the connecting spring 302, which reduces the loosening rate of the connection between the line and the expansion interface 103, ensures reliability, and avoids the situation of the line becoming loose or falling off due to vehicle bumps.

[0021] In this second embodiment, based on the first embodiment, a helical spring is provided between the side limiting insert 106 and the main expansion module 1. The helical spring supports the side limiting insert 106 and the side support rod 105 to maintain a sliding state. A helical spring is also provided between the secondary expansion frame 2 and the lower positioning insert 201. The helical spring supports the secondary expansion frame 2 and the lower positioning insert 201 to maintain a sliding state. The main expansion module 1 can be fixedly installed on the roof for use.

[0022] The working principle of this embodiment is as follows: The lower connecting base 102 is fixedly connected to the bus. The main expansion module 1 adjusts its angle and direction by sliding the lower spherical slide column 101 and the lower connecting base 102 through the spherical structure. The lower spherical slide column 101 and the lower connecting base 102 are equipped with a rubber strip to provide active damping. The main expansion module 1 is seamlessly connected to the sub-expansion frame 2 through the interface, thereby increasing the number of expansion interfaces 103 and the capacity of the interface expansion dock. The modular expansion can meet the high-speed data transmission requirements of on-board monitoring, traction control and other equipment, and can also adapt to the fast charging requirements of passengers' mobile phones, tablets and other electronic devices. The sub-expansion frame 2 supports hot-swapping and plug-and-play. When new interface requirements are added, there is no need to replace the entire expansion dock. Only the corresponding sub-expansion frame 2 needs to be installed, which reduces the cost of single interface expansion. The interface combination can be flexibly configured according to operational needs. For example, the driver's cabin focuses on industrial interfaces, and the passenger area focuses on charging interfaces, which is suitable for different vehicle models such as subways and intercity electric buses. The line protection bracket 3 and the upper fixed bracket 301 form a clamping force under the action of the connecting spring 302. The line protection bracket 3 and the upper fixed bracket 301 wrap around the interface connection line to achieve radial clamping of the line. At the same time, the line protection bracket 3 adjusts its position along the 360° position of the outer annular slide groove 104. The line protection bracket 3 realizes the following of the bending direction of the line, reduces the loosening rate of the connection between the line and the expansion interface 103, ensures reliability, and avoids the situation where the interface and line become loose during the vibration of the electric bus, resulting in data interruption and charging failure. The side support rod 105 and the lower positioning plug 201 are horizontally slid-in connected. The vertical sliding of the lower positioning plug 201 and the sliding of the side support rod 105 limit the horizontal displacement. The side support rod 105 realizes full-dimensional limit of the sub-extension frame 2. The displacement of the sub-extension frame 2 is controlled in the vibration environment, and the offset is further reduced. This avoids the sub-extension frame 2 from being easily offset and loosened under vibration due to plugging and unplugging connection, resulting in poor interface contact.
