Description

Technical Field

[0001] The present application belongs to the technical field of battery replacement for electric vehicles, and in particular, relates to an automatic anti-retraction device and an automatic power supply system for a battery compartment of an electric vehicle battery replacement system. Background Art

[0002] In the current new energy vehicle industry, battery swapping technology, as a key technology, is being studied and applied in depth by more and more companies. This technology allows the battery of a car to be quickly replaced, which greatly reduces the charging time of electric vehicles and improves the convenience of use. The most widely used system in the market is the chassis battery swapping system, which is characterized by the battery being connected to the vehicle through the bottom and fixed using a mechanical positioning system.

[0003] The chassis battery swap system mainly relies on locating pins to fix the position of the battery in the battery compartment, while the water and electricity connectors are connected from above the battery. During the battery swap process, the battery is lifted above the battery rack using a fork, and then lowered vertically so that the battery's locating pin holes are correctly aligned and fall on the locating pins of the battery rack. This step achieves horizontal fixation of the battery.

[0004] The battery positioning system in the front-end battery swap field usually adopts the method of cylinder plus V-shaped positioning block. The battery swap trolley pushes the battery from the side of the battery rack to the specified position, and then corrects and fixes the position of the battery through the V-shaped positioning block pushed by the cylinder.

[0005] The rapid, safe and reliable positioning of the battery compartment, as well as the locking of the battery for charging and the unlocking of the battery for power withdrawal are among the key technical challenges in ensuring battery replacement efficiency and battery safety. Utility Model Content

[0006] In view of the deficiencies existing in the related technologies, the utility model provides an automatic anti-retraction device for the battery compartment of an electric vehicle battery replacement system, which solves the technical problems of fast, safe and reliable positioning of the battery compartment, as well as locking the battery during charging and unlocking it when drawing power.

[0007] In a possible embodiment, an automatic anti-recoil device for the battery compartment of an electric vehicle battery replacement system is provided, comprising: a baffle, a first connecting rod, a second connecting rod, a pressure wheel, a spring and an anti-recoil seat. Among them, one end of the baffle is connected to the anti-recoil seat through a pin shaft, and the other end is connected to the first connecting rod; the baffle is not connected to the other end of the anti-recoil seat, and a spring is provided below. The spring is installed on the anti-recoil seat below the baffle, and the baffle is lifted under the action of the spring. One end of the first connecting rod is connected to the baffle through a pin shaft, and the other end is connected to the middle part of the second connecting rod through a pin shaft. The pressure wheel is connected to one end of the second connecting rod, and the other end of the second connecting rod is installed on the anti-recoil seat through a pin shaft. When the pressure wheel rotates along the pin shaft connected to the anti-recoil seat, it drives the second connecting rod and the first connecting rod to move, and drives the baffle connected to the first connecting rod to press together.

[0008] In a possible implementation, the device is installed behind the moving object, and when the baffle is pressed, the plane of the baffle after pressing is flush with the moving plane of the object, and the object moves along the pressing direction.

[0009] In a possible implementation, after the object passes through, the blocking piece is bounced up by a spring to prevent the object from moving backward, so that the blocking piece prevents the object from moving backward.

[0010] In a possible implementation manner, the pressure wheel is fixedly connected to the second connecting rod via a connecting member.

[0011] In a possible implementation manner, the pressure wheel is connected to the second connecting rod via a pin.

[0012] In one possible implementation, the object is a battery.

[0013] In one possible embodiment, an automatic power extraction system for a battery compartment of an electric vehicle battery exchange system is provided, including an electric push rod, which is arranged corresponding to an automatic anti-retraction device of the battery compartment of the electric vehicle battery exchange system. The electric push rod is controlled to push a pressure wheel, and the forward pushing action of the pressure wheel drives the movement of the first connecting rod and the second connecting rod, so that the baffle is pressed and flush with the moving plane of the object, allowing the object to pass over the baffle.

[0014] Based on the above technical solution, the utility model solves the problem of battery retraction that may occur during the battery replacement process by combining components such as a baffle, a first connecting rod, a second connecting rod, a pressure wheel, a spring and a retraction stop seat. Specifically, the device uses the pressing action of the baffle to align with the moving plane of the object to prevent the battery from being unstable and accidentally moving during placement. In addition, the use of a spring enables the baffle to automatically return after the object passes, increasing the convenience of use and the reliability of the system. This automated retraction function significantly improves the safety and efficiency of the electric vehicle battery replacement system. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the examples of the present application to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] In order to solve the technical problems of fast, safe and reliable positioning of the battery compartment, as well as locking the battery during charging and unlocking it for power extraction, the present application provides an automatic anti-retraction device and a power extraction system for the battery compartment of an electric vehicle battery replacement system.

[0026] See also Figure 1In a possible embodiment, the automatic anti-recoil device of the battery compartment of the electric vehicle battery replacement system includes: a baffle 21.1, a first connecting rod 21.2, a second connecting rod 21.3, a pressure wheel 21.4, a spring 21.5 and an anti-recoil seat 21.6; wherein, one end of the baffle 21.1 is connected to the anti-recoil seat 21.6 through a pin shaft, and the other end is connected to the first connecting rod 21.2; the baffle 21.1 is not connected to the other end of the anti-recoil seat 21.6, and a spring 21.5 is provided below, and the spring 21.5 is installed on the anti-recoil seat 21.6 below the baffle 21.1, and the baffle 21.1 is lifted under the action of the spring. One end of the first connecting rod 21.2 is connected to the baffle 21.1 through a pin shaft, and the other end is connected to the middle part of the second connecting rod through a pin shaft. The pressure wheel is connected to one end of the second connecting rod, and the other end of the second connecting rod is installed on the anti-recoil seat through a pin shaft. When the pressing wheel rotates along the pin shaft connected to the stop seat, the second connecting rod and the first connecting rod are driven to move, and the blocking piece connected to the first connecting rod is driven to be pressed.

[0027] Baffle 21.1: It is automatically lifted up after the battery passes through to prevent the battery from moving backward.

[0028] The first connecting rod 21.2 and the second connecting rod 21.3 transmit the power of the pressing wheel 21.4 to control the lifting and pressing of the baffle.

[0029] Pressure wheel 21.4: receives external force such as the push of the third electric push rod, and converts the force into the movement of the baffle.

[0030] Spring 21.5: provides restoring force for the baffle to ensure that it can automatically return to the initial position when no external force is applied, thereby increasing the response speed and reliability of the system.

[0031] During operation, the pressing wheel 21.4 is pushed manually or by the third electric push rod 28, and the pressing wheel rotates to drive the second connecting rod 21.3, and then pushes the first connecting rod 21.2, and finally the blocking piece 21.1 moves from the stop seat 21.6 to the pressing position. After the battery passes through the blocking piece 21.1, the blocking piece can automatically lift up to prevent the battery from retreating.

[0032] In the above scheme, the automatic anti-retraction device of the battery compartment of the electric vehicle battery replacement system adopts a complex mechanical linkage system to achieve efficient and safe battery positioning and prevent the battery from accidentally moving. The baffle 21.1 is mechanically connected to the anti-retraction seat 21.6 and connected to the pressure wheel 21.4 through the first connecting rod 21.2, allowing it to move when the pressure wheel is subjected to external driving force, and automatically return to the initial blocking position by the restoring force provided by the spring 21.5 without external force. This setting ensures that the baffle can be lifted immediately after the battery passes through to prevent the battery from retreating, improves the convenience and efficiency of operation, and ensures safety and reliability during operation.

[0033] In a possible implementation, the device is installed behind the object 30 when it is moving. When the baffle 21.1 is pressed, the plane of the baffle after pressing is flush with the moving plane of the object 30, and the object moves along the pressing direction.

[0034] By adjusting the lifting and pressing of the baffle 21.1, the smoothness and safety of the battery replacement process is ensured, while the intervention of the operator is reduced and the automation level of the entire system is improved.

[0035] In a possible implementation, after the object 30 passes through, the blocking piece 21.1 is bounced up by the spring 21.5 to prevent the object from moving backward, so that the blocking piece prevents the object from moving backward.

[0036] When an object 30, such as a battery or other related components, passes through the baffle 21.1, the baffle will automatically rise due to the action of the spring 21.5 to prevent the object 30 from moving in the opposite direction. This automatic rebound mechanism ensures that after the object passes through the baffle, it will not accidentally retreat due to any external factors such as machine vibration.

[0037] This automatic locking function enhances the safety of the electric vehicle battery replacement system, ensures the stability of the battery during charging or replacement, and prevents accidental falling off or displacement, thereby protecting the safety of operators and equipment.

[0038] In a possible implementation manner, the pressure wheel 21.4 is fixedly connected to the second connecting rod via a connecting piece.

[0039] The connection between the pressure wheel 21.4 and the second connecting rod 21.3 is achieved through a fixed connecting piece. This connection mode provides a stable and strong structure, ensuring the stability and accuracy of the transmission during the process of the pressure wheel pushing the baffle 21.1 to press together.

[0040] By using fixed connections, the mechanical strength and durability of the entire system are improved, especially in high-load and high-frequency operating environments, increasing the reliability of the equipment.

[0041] Fixed connectors can be replaced with adjustable connectors or quick-release connectors as needed to facilitate maintenance and adjustment to meet different working conditions and maintenance requirements.

[0042] In a possible implementation, the pressure wheel 21.4 is connected to the second connecting rod 21.3 via a pin.

[0043] Through the pin connection, the pressure wheel 21.4 and the second connecting rod 21.3 can achieve relative rotation. This connection mode provides a certain flexibility, allowing the pressure wheel 21.4 to automatically adjust its angle according to the position of the baffle 21.1 during the pushing process.

[0044] In one possible implementation, the object 30 is a battery.

[0045] Object 30 is a battery, and the device is used in an electric vehicle battery replacement system.

[0046] In a possible implementation, a battery compartment automatic power supply system for an electric vehicle battery replacement system is provided. Figure 2 , including a third electric push rod 28, the third electric push rod 28 is arranged corresponding to the automatic anti-recoil device of the battery compartment of the electric vehicle battery replacement system, that is, the automatic anti-recoil device 21 in the figure, and the third electric push rod 28 is controlled to push the pressure wheel, and the forward pushing action of the pressure wheel drives the movement of the first connecting rod and the second connecting rod, so that the baffle is pressed and flush with the moving plane of the object, allowing the object to pass over the baffle.

[0047] The third electric push rod 28 is controlled by the electric control system, providing a power source, so that the pressure wheel 21.4 can be pushed as needed to achieve automatic baffle pressing and releasing, simplifying the operating process and improving the response speed and accuracy of the system.

[0048] By integrating the third electric push rod 28, the device improves the automation level of the battery replacement process, reduces manual operations, and improves the efficiency and safety of battery replacement.

[0049] The third electric push rod 28 can be replaced with different types of electric or hydraulic drive devices as needed to adapt to different operating speeds and torque requirements, or a more suitable drive mode can be selected according to different working environments, such as using a hydraulic system in an explosion-proof environment.

[0050] The beneficial effects of the automatic anti-retraction device for the battery compartment of the electric vehicle battery replacement system of the present application are mainly reflected in the following aspects:

[0051] Improved safety: The device automatically rises after the battery passes through an automatic baffle mechanism to prevent the battery from accidentally rolling back, significantly improving the safety of the battery replacement process. The setting to prevent the battery from rolling back reduces the risk during the operation and ensures the safety of the operator and equipment.

[0052] Convenience of operation: Through an automated control system, such as the coordinated use of the third electric push rod 28 and the pressure wheel mechanism, the system can automatically adjust the position of the baffle, reducing the need for manual operation and improving the convenience and efficiency of the battery replacement operation.

[0053] Structural stability: By adopting pin connection or fixed connecting parts, the connection between the pressure wheel and the connecting rod is ensured to be firm and reliable, which increases the mechanical strength and durability of the entire device, so that the device can adapt to continuous high-frequency operation without being easily damaged.

[0054] High degree of automation: The automation setting of the entire system reduces the possibility of human operation errors, improves the operating efficiency of the battery swap station and the battery swap speed, and can significantly improve service capabilities and response speed, especially in high-demand commercial operation environments.

[0055] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0056] The above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution requested for protection in the present application.
