Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of electric vehicles, and in particular to an intelligent louver heat dissipation device for comprehensive heat dissipation of a battery pack of a flat-pedal electric vehicle and a flat-pedal electric vehicle. Background Art

[0002] The battery compartment of a flat-pedal electric vehicle is typically located in the flat pedal area. In some low-end electric vehicles, heat dissipation is typically achieved by surrounding the battery compartment with a large portion of the exposed batteries. The plastic housing surrounding the battery compartment and the battery compartment utilize a non-precision, fully enclosed structure. This effectively leaves ample space around the battery compartment for heat dissipation. However, this type of electric vehicle is also susceptible to dust, sand, rain, and external debris, which can cause the battery pack to become damp and short-circuit, seriously affecting its performance and lifespan while also posing a safety hazard. Furthermore, this cooling method results in a crude design with a lack of detail, which is inconsistent with the refined and aesthetically pleasing design philosophy of modern electric vehicles.

[0003] In some high-end electric vehicles, the plastic shell and battery compartment are precision fully enclosed structures. Heat dissipation for the batteries is achieved through the use of active air inlets and outlets, which draw air into the battery pack and expel heat through a specifically designed ventilation duct system. This type of ventilation duct typically has an air inlet located in the upper portion of the battery compartment. While the lower and bottom portions of the battery pack are designed with air outlets, the limited air inlet area and narrow, long channels, coupled with increased air flow resistance, make it difficult to achieve uniform heat dissipation within the battery pack. This results in good heat dissipation in the upper portion of the battery while insufficient heat dissipation in the lower portion. Furthermore, when the electric vehicle is stationary, the airtightness of the space surrounding the battery compartment makes it difficult for external air to circulate, further leading to insufficient heat dissipation from the battery pack. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent louver heat dissipation device for comprehensive heat dissipation of the battery pack of a flat-pedal electric vehicle, aiming to solve the technical problems of uneven heat dissipation and poor heat dissipation effect of the battery pack of the existing flat-pedal electric vehicle, especially to solve the problem of insufficient heat dissipation at the bottom of the battery.

[0005] To achieve the above objectives, the present invention provides an intelligent louver heat dissipation device for comprehensive heat dissipation of the battery pack of a flat-pedal electric vehicle. The device is integrally mounted below the batteries in the flat-pedal area and comprises, in descending order, a battery pack tray, a shock-absorbing suspension structure, an elastic transmission assembly, a louver-operating plate, a louver-heat dissipation vibration assembly, and an anti-collision protection frame. This intelligent louver heat dissipation device utilizes the vibration energy generated during the operation of a flat-pedal electric vehicle to drive the louver structure to vibrate, forming an upward, concentrated airflow channel that directs wind force into the gaps between adjacent batteries, achieving comprehensive and uniform heat dissipation of the battery pack.

[0006] Specifically, the battery pack tray is arranged on the frame of the flat-pedal electric vehicle for installing the battery pack; the shock-absorbing suspension structure is arranged at the lower end of the battery pack tray, including a suspension connecting plate fixed on the frame and a shock-absorbing spring connected between the suspension connecting plate and the battery pack tray; the elastic transmission assembly is arranged below the shock-absorbing suspension structure, including a transmission pin passing through the shock-absorbing spring and the suspension connecting plate, and a transmission folding plate connected to the lower end of the transmission pin; the louver toggle plate is rotatably hinged to the mounting protective cover fixed on the frame, one end of which abuts against the transmission folding plate of the elastic transmission assembly, and the other end passes through the toggle notch provided on the mounting protective cover; the louver heat dissipation vibration assembly is installed in the mounting protective cover, and one end is connected to the mounting protective cover The vibrating hinged end is formed by rotating and hingedly hinged by a hinged short shaft, and the other end is a free vibrating end, and is detachably in contact with the louver toggle plate; the louver heat dissipation vibrating assembly includes a connecting frame, multiple heat dissipation blades and a vibrating connecting beam, the connecting frame is a rectangular frame that passes through the upper and lower parts and is rotatably hinged to the mounting protective cover, the heat dissipation blade includes a blade part and a connecting rotating part symmetrically arranged at both ends, the connecting rotating part is rotatably hinged to the inner wall of the connecting frame through a hinge hole and is provided with a connecting hole on the side away from the blade, the vibrating connecting beam is arranged along both sides and passes through the connecting holes of each heat dissipation blade to connect the multiple heat dissipation blades into one; the anti-collision protection frame is fixedly connected to the lower part of the connecting frame of the louver heat dissipation vibrating assembly.

[0007] The main advantage of this structure is that through the synergistic effect of various components, the vibration energy generated during driving is converted into heat dissipation power, forming a bottom-up forced airflow channel, especially for the lower area of ​​the battery that is difficult to cover with traditional heat dissipation systems, to achieve comprehensive and uniform heat dissipation of the battery pack, thereby improving the service life and working efficiency of the battery pack, while reducing the safety risks of battery overheating.

[0008] The present invention further features an outwardly protruding vibrating plate at the end of the vibrating connecting beam, as well as a toggle plate at the end of the louver toggle plate away from the elastic transmission assembly. The toggle plate has a larger area than the vibrating plate. This design increases the contact area for thrust transmission, ensuring stability and reliability of thrust transmission and improving vibration efficiency.

[0009] The present invention also includes an anti-collision protection frame, fixedly connected to the lower portion of the connecting frame of the louver heat dissipation vibration assembly. This grid-like design comprises multiple circular tubes intersecting horizontally and vertically. This design not only protects the louver heat dissipation vibration assembly from damage by external obstacles, but more importantly, when the flat-pedal electric vehicle encounters a high obstacle, the anti-collision protection frame rotates with the louver heat dissipation vibration assembly to avoid the obstacle, preventing serious safety accidents such as rollovers, thereby greatly improving driving safety.

[0010] The present invention also features a movable support structure, comprising support columns symmetrically positioned on the two outer walls of the connecting frame and curved sliding grooves symmetrically positioned on the two inner walls of the mounting shield. The two support columns are mounted within the two curved sliding grooves, respectively. Furthermore, the blades are curved, creating an overlap between adjacent blades when the louvered cooling oscillating assembly is closed. The movable support structure ensures stable and reliable rotation of the louvered cooling oscillating assembly. The curved blade design not only increases the airflow velocity and volume generated by the oscillation, but also creates an overlapping seal when closed, preventing debris from entering the cooling system and protecting the battery pack.

[0011] The present invention incorporates a vibration-activated mechanism at the free-vibrating end to control the downward opening or upward closing of the louver heat dissipation vibration assembly. Three implementation methods are provided: a traction column and traction rope, a connecting rod assembly, and an electromagnet and magnetic attraction block. These three control methods provide the driver with flexible options, allowing for easy operation based on actual needs and personal preferences, thereby enhancing the device's practicality and applicability.

[0012] The present invention also provides a flat-pedal electric vehicle utilizing the aforementioned intelligent louver heat dissipation device. The openings of the louver heat dissipation vibration assembly are arranged from small to large along the vehicle's front to rear, forming a tilted louver windward surface. This tilted design absorbs a large amount of airflow generated during driving and directs it upward to form a concentrated airflow channel, thereby improving heat dissipation efficiency.

[0013] In summary, the intelligent louver heat dissipation device of the present invention achieves comprehensive and uniform heat dissipation from the battery pack by cleverly utilizing the vibration energy generated during the operation of a flat-pedal electric vehicle. This particularly addresses the problem of insufficient heat dissipation from the lower portion of the battery, which is difficult to address with traditional cooling systems. Furthermore, the device boasts a rational design, compact structure, safety, reliability, and ease of operation, offering significant practical value and promising prospects for widespread application.

[0014] The beneficial effects of the present invention are: Highly efficient heat dissipation effect: The present invention utilizes the vibration energy generated during the running of the flat-pedal electric vehicle to drive the louver structure to vibrate, forming an upward concentrated airflow channel. This particularly solves the problem of insufficient heat dissipation in the lower part of the battery that is difficult to cover with traditional heat dissipation systems, achieves comprehensive and uniform heat dissipation of the battery pack, and effectively extends the battery life.

[0015] Intelligent energy-saving design: This device does not require additional electric power to drive, and cleverly converts driving vibration energy into heat dissipation power, realizing the environmental protection concept of "energy recovery and reuse" and reducing the energy consumption of electric vehicles.

[0016] Safety protection function: The designed anti-collision protection frame not only protects the louver heat dissipation vibration components, but more importantly, it can automatically avoid obstacles when encountering them, preventing safety accidents such as rollovers, greatly improving driving safety.

[0017] Optimized structural design: The arc-shaped design of the louver blades increases airflow speed and volume, and the closed state forms an overlapping seal, effectively preventing debris from entering the cooling system; the movable support structure ensures the stability and reliability of component rotation.

[0018] Convenient and flexible operation: The three vibration start control methods provided (traction rope, connecting rod assembly, and electromagnet control) allow the driver to flexibly choose according to actual needs and habits, thereby improving the practicality of the device.

[0019] Adaptive system: The inclined windward side design of the blinds can efficiently receive the airflow during driving. The disordered and pulsating characteristics of the airflow effectively prevent dust accumulation and ensure long-term heat dissipation effect.

[0020] Compact and integrated structure: The whole device is installed under the battery in the flat pedal area. It has a compact structure and is integrated with the original structure of the electric vehicle without affecting the overall aesthetics and ease of use of the vehicle.

Detailed implementation manners

[0024] Example 1: Refer to Figure 1-Figure 2 , this example provides an intelligent shutter heat dissipation device for comprehensive heat dissipation of the battery pack of a flat-step electric vehicle. The device aims to solve the technical problems of uneven heat dissipation and poor heat dissipation effect of the existing battery packs of flat-step electric vehicles, especially the problem of insufficient heat dissipation at the lower part of the battery. The intelligent shutter heat dissipation device of the present invention utilizes the vibration energy generated during the driving process of the flat-step electric vehicle to drive the shutter structure to vibrate, forming an upward concentrated air flow channel, guiding the wind force into the gaps between adjacent batteries, and realizing comprehensive and uniform heat dissipation of the battery pack 01. The device is installed below the battery pack 01, and the battery pack 01 is installed on the flat-step electric vehicle frame 02 through the battery pack carrier box 10.

[0025] The battery pack carrier box 10 is provided with battery installation positions 11 corresponding to multiple batteries of the battery pack 01 one by one. In this example, the battery pack 01 adopts a "field" - shaped layout design, with four batteries configured. Therefore, the battery installation positions 11 are provided with four and are distributed in a "field" - shaped manner. There are gaps between adjacent battery installation positions 11 to keep a certain heat dissipation space between each battery, thereby increasing the heat dissipation area. Importantly, the bottom of the battery pack carrier box 10 is designed as a mostly hollow structure, and multiple waterproof ventilation holes 13 are opened at the bottom of the installation position to form a ventilation notch 14. This bottom - hollow design provides a sufficient air flow channel for the intelligent shutter heat dissipation device of the present invention, ensuring that the heat dissipation air flow can enter from the bottom and be effectively conducted to the gaps between each battery inside the battery pack.

[0026] To ensure the stability of the batteries after installation, this embodiment is equipped with a battery fixing structure 20 that cooperates with the battery pack tray 10. This battery fixing structure 20 is rationally designed to firmly secure the batteries while maintaining appropriate gaps between the batteries. This facilitates the airflow generated by the intelligent louver heat dissipation device of the present invention to fully circulate within the battery pack 01, thereby improving heat dissipation efficiency.

[0027] refer to Figure 2-Figure 7 The intelligent louver heat dissipation device of this embodiment is a key innovation in solving the heat dissipation problem of battery packs in flat-pedal electric vehicles. The device primarily comprises a shock-absorbing suspension structure 30, an elastic transmission assembly 40, a louver shifting plate 50, a louver heat dissipation vibration assembly 60, and a mounting protective cover 70. These components work together to form a system that actively dissipates heat by utilizing driving vibration energy.

[0028] The mounting protection cover 70 is a rectangular frame with upper and lower ends passing through, fixed to the vehicle frame 02, and serves as an external protection and support structure for the entire heat dissipation device. The mounting protection cover 70 is symmetrically provided with two toggle notches 71 for the movable passage of the shutter toggle plate 50.

[0029] The louver heat dissipation vibration assembly 60 is the core component of the system, responsible for forming an upward heat dissipation airflow channel. This assembly is installed in the installation protective cover 70. Its end near the front of the electric vehicle is rotatably hinged to the installation protective cover 70 through two hinged short shafts 611. This end is the vibration hinge end 601, and the other end is the free vibration end 602. When the louver heat dissipation vibration assembly 60 is drooped and opened, its opening increases from small to large along the direction from the front to the rear of the electric vehicle, forming an inclined louver windward surface. This inclined design can receive a large amount of airflow generated during driving and guide it to form an upward concentrated airflow channel.

[0030] The louver heat dissipation vibration assembly 60 is composed of a connecting frame 61, a plurality of heat dissipation blades 62 and a vibration connecting beam 63: The connecting frame 61 is in the shape of a rectangular frame that passes through from top to bottom and is rotatably hinged to the mounting protective cover 70; The heat dissipation blade 62 includes a blade portion 621 and a connecting rotating portion 622 symmetrically provided at both ends. The rotating connecting portion is rotatably hinged to the inner wall of the connecting frame 61 through a first hinge hole 6221. At the same time, a connecting hole 6222 is provided on the side away from the blade. The vibrating connecting beams 63 are arranged along both sides, and each vibrating connecting beam 63 passes through the connecting hole 6222 of each heat dissipation blade 62, connecting the multiple heat dissipation blades 62 into one body so that they can move in coordination.

[0031] The free flapping end 602 is provided with a flapping start structure 64 for controlling the drooping opening or upward retraction closing of the louver heat dissipation flapping component 60. The end of the flapping connecting beam 63 is provided with a protruding flapping plate 631, which is the key contact point for receiving external thrust.

[0032] The louver拨动 plate member 50 is an intermediate transmission mechanism connecting the louver heat dissipation flapping component 60 and the elastic force transmission component 40. It is rotationally hinged to the installation protection cover 70, with one end contacting the elastic force transmission component 40 and the other end passing through the拨动 notch 71 to be separably contacted with the flapping plate 631 of the louver heat dissipation flapping component 60. Two拨动 plates 51 are provided at one end of the louver拨动 plate member 50 away from the elastic force transmission component 40, and their area is larger than that of the flapping plate 631 to ensure the stability of thrust transmission.

[0033] The shock absorption suspension structure 30 is the energy source of the whole system and is arranged at the lower end of the battery pack support box 10, including a suspension connecting plate 31 and a shock absorption spring 32. The suspension connecting plate 31 is in a hollow "return" shape and is firmly connected to the vehicle frame 02 through a fixed bracket. The shock absorption spring 32 is connected between the suspension connecting plate 31 and the battery pack support box 10, which not only protects the battery pack from vibration damage but also collects the driving vibration energy for driving the heat dissipation system.

[0034] The elastic force transmission component 40 is a key component for energy transmission and is connected to the shock absorption spring 32, including a transmission nail 41 and a transmission folding plate 42. The transmission nail 41 sequentially passes through the shock absorption spring 32 and the suspension connecting plate 31, and the lower end is connected to the transmission folding plate 42. The lower end of the transmission folding plate 42 abuts against the edge of the louver拨动 plate member 50, and this design increases the length of the force arm and improves the torque transmission efficiency.

[0035] When the flat-tread electric vehicle is running, the shock absorption suspension structure 30 absorbs vibration to generate compression energy, which is transmitted to the louver拨动 plate member 50 through the elastic force transmission component 40. The louver拨动 plate member 50 pushes the louver heat dissipation flapping component 60 to flap up and down, thereby forming a forced upward air flow channel at the bottom of the battery pack. This forced upward air flow is specifically aimed at the bottom and lower section areas of the battery, solving the dead angle problem that is difficult to cover by the traditional heat dissipation system. At the same time, the intelligent louver heat dissipation device of the present invention can cooperate with the existing ventilation system above the battery pack to jointly form a three-dimensional heat dissipation network with upper and lower penetration, realizing comprehensive and uniform heat dissipation of the battery pack. In addition, the up-and-down flapping characteristics of the louver heat dissipation flapping component 60 make the air flow show certain disorder and pulsation characteristics, effectively preventing the deposition and accumulation of dust in specific areas, avoiding the formation of dust accumulation dead angles with poor heat dissipation effects, and further improving the long-term reliability and maintenance convenience of the heat dissipation system.

[0036] To prevent damage to the louver heat dissipation vibration assembly 60 when encountering obstacles, and more importantly, to ensure driving safety, this embodiment incorporates an anti-collision protection frame 80. The anti-collision protection frame 80 is fixedly connected to the lower portion of the connecting frame 61 of the louver heat dissipation vibration assembly 60, serving as an extended protective structure for the connecting frame 61. Because the anti-collision protection frame 80 is fixedly connected to the connecting frame 61, it moves synchronously with the rotation of the louver heat dissipation vibration assembly 60. The anti-collision protection frame 80 is grid-shaped, composed of multiple circular tubes intersecting horizontally and vertically. When a flat-pedal electric vehicle encounters a high obstacle during driving and the driver cannot dodge it in time, the anti-collision protection frame 80 will first contact the obstacle without forcibly interfering, thereby preventing serious safety accidents such as rollovers. As the flat-pedal electric vehicle moves forward, the obstacle will move relative to the anti-collision protection frame 80 toward the free vibration end 602, directly pushing the connecting frame 61, causing the free vibration end 602 to rotate upward around the vibration hinge end 601. This allows the entire system to adaptively avoid obstacles. After passing the obstacle, the free vibrating end 602 automatically rotates and droops under its own weight, and the anti-collision protection frame 80 also returns to its normal position and resumes normal operation. This structural design not only protects the device itself, but also ensures driving safety to a greater extent and avoids dangers that may occur in extreme situations.

[0037] The grid-like design of the anti-collision protection frame 80 allows it to communicate with the outside world, ensuring that the louvered heat dissipation vibration assembly 60 can properly absorb external air and fan it into the battery pack 01. Furthermore, the circular tube structure allows the anti-collision protection frame 80 to slide along the smooth curved surface of the tube when encountering obstacles, preventing the obstacles from constantly hitting the anti-collision protection frame 80 and preventing the flat-pedal electric vehicle from continuing to move forward.

[0038] To ensure the stability of the rotation of the louver heat dissipation vibration assembly 60 relative to the mounting protective cover 70, this embodiment incorporates a movable support structure 90. This movable support structure 90 comprises support columns 91 symmetrically located on the two outer walls of the connecting frame 61, and arcuate sliding grooves 92 symmetrically located on the two inner walls of the mounting protective cover 70. The two support columns 91 are respectively mounted within the two arcuate sliding grooves 92. When the louver heat dissipation vibration assembly 60 rotates about the two hinged short shafts 611, the support columns 91 slide within the arcuate sliding grooves 92, thus accommodating the rotation requirements of the louver heat dissipation vibration assembly 60 while providing additional support force, ensuring a smooth and reliable rotation process.

[0039] The blades 621 of the louvered heat dissipation vibration assembly 60 are curved. This design increases the airflow velocity generated by the upward and downward vibrations, increasing air volume and improving heat dissipation. Furthermore, when the louvered heat dissipation vibration assembly 60 is pulled upward and closed, adjacent blades 621 overlap, sealing the adjacent blades. The leading and trailing blades overlap with the connecting frame 61, forming a complete closed state. This closed state effectively prevents debris such as small stones and fallen leaves from entering the louvered heat dissipation assembly, preventing debris from being blown into the battery pack 01 during vibration, thereby protecting the battery pack.

[0040] In order to control the downward opening and upward closing of the free vibrating end 602, a vibrating start structure 64 is designed in this embodiment. This structure can be implemented in the following three ways: 1. A traction post is installed at the free oscillating end 602 of the louver heat dissipation oscillating assembly 60. A traction rope is threaded through the traction post and passed through the vehicle frame 02 to the front of the flat-pedal electric vehicle, facilitating driver control. Pulling the traction rope upward pulls the free oscillating end 602 upward to close it; releasing the traction rope causes the free oscillating end 602 to droop open under its own weight.

[0041] 2. A connecting rod assembly is installed at the end of the shutter swivel plate 50 away from the vibrating plate 631. The connecting rod assembly extends through the vehicle frame 02 and reaches the front section of the flat-pedal electric vehicle. By operating the connecting rod assembly, the end of the shutter swivel plate 50 away from the vibrating plate 631 is pressed downward, causing the swivel plate 51 to push the free vibrating end 602 upward, achieving upward closure. The connecting rod assembly is then controlled to keep the swivel plate 51 horizontal, causing the free vibrating end 602 to droop open under its own weight.

[0042] 3. An electromagnet is installed at the lower end of the suspension connecting plate 31, near the free oscillating end 602, and a magnetic attraction block is installed at the corresponding position on the louver heat dissipation oscillating assembly 60. The opening and closing of the free oscillating end 602 are controlled by turning the electromagnet on and off. When powered on, the electromagnet attracts the magnetic attraction block, driving the free oscillating end 602 upward, achieving an upward pull and closing. When powered off, the free oscillating end 602 opens downward under its own weight.

[0043] The working process of the intelligent louver heat dissipation device of the present invention is as follows: When a driver rides a flat-pedal electric vehicle, the vibration activation mechanism 64 first controls the free vibrating end 602 of the louver heat dissipation vibrating assembly 60, causing it to rotate and droop relative to the vibrating hinged end 601 until the vibrating plate 631 rests on the upper end of the shifting plate 51. When the road surface is uneven or vibrating, the shock-absorbing spring 32 of the shock-absorbing suspension structure 30 acts as a buffer, protecting the battery pack 01 while also accumulating vibration energy.

[0044] The shock-absorbing spring 32 accumulates the impact force of the vibration and transmits it to the elastic transmission assembly 40, causing it to move downward. This drives one end of the shutter shifting plate 50 to rotate downward about its hinged joint. The shifting plate 51 at the other end then rotates upward and pushes the vibrating connecting beam 63 upward through the vibrating plate 631. The vibrating connecting beam 63 drives the heat dissipating blades 62 to rotate about the hinged joint, causing the heat dissipating blades 62 to vibrate upward.
