The locking mechanism includes at least two locking components, which cooperate with the same locking shaft component on a battery pack to lock the battery pack. By cooperating with the same locking shaft component, the battery pack is stably locked to the locking mechanism. That is, by using multiple locking components, the contact area between the locking components and the locking shaft component is increased, improving the structural strength and load-bearing capacity of the locking mechanism.

Description

Technical Field

[0001] The present invention relates to a locking mechanism and an electric vehicle comprising the same. Background Technology

[0002] In recent years, new energy vehicles have developed rapidly. Electric vehicles, which rely on batteries as their driving energy, have the advantages of zero emissions and low noise. As the market share and usage frequency of electric vehicles are increasing, electric commercial vehicles, such as electric heavy-duty trucks and electric light-duty trucks, are gradually appearing in their respective application scenarios. At the same time, battery swapping stations for replacing battery packs for electric trucks have been built.

[0003] In existing technologies, battery packs are typically installed on electric vehicles using locking mechanisms. However, commercial vehicles such as electric trucks require larger battery pack capacities, resulting in generally heavier battery packs. Existing locking mechanisms have poor structural strength and load-bearing capacity, making them unsuitable for heavy battery packs and leading to poor stability in battery pack locking. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of poor structural strength and load-bearing capacity of the locking mechanism in the prior art, which leads to poor stability of battery pack locking, and to provide a locking mechanism and an electric vehicle including the same.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] The present invention discloses a locking mechanism comprising at least two locking components, the at least two locking components being used to cooperate with the same locking shaft component on a battery pack to lock the battery pack.

[0007] In this solution, the above-mentioned structural form is adopted, and the battery pack is stably locked to the locking mechanism by at least two locking components cooperating with the same locking shaft component. That is, by using multiple locking components, the cooperation area between the locking components and the locking shaft component is increased, the structural strength and load-bearing capacity of the locking mechanism are improved, and it can be applied to heavier battery packs, improving the stability and reliability of the locking of the locking shaft component, thereby improving the stability and reliability of the battery pack being locked to the locking mechanism.

[0008] Preferably, when the locking mechanism is in the locked state, the plurality of locking components at least partially overlap in the extending direction of the locking shaft component, and the locking shaft component is locked at the overlapping position of the plurality of locking components.

[0009] In this solution, the above-mentioned structural form increases the locking area of ​​the locking shaft component and the locking component, and the locking shaft component can be stably locked at the overlapping position of multiple locking components, thereby improving the locking stability and reliability of the locking shaft component.

[0010] Preferably, the locking mechanism is provided with a first opening. When the locking mechanism is in the unlocked state, the locking shaft component enters or leaves the first opening in the vertical direction. When the locking mechanism is in the locked state, a plurality of the locking components form a locking area connected to the first opening to lock the locking shaft component within the locking area.

[0011] In this solution, using the above-described structure, when the locking component needs to be locked to the locking mechanism, the locking shaft component enters the locking component through the first opening and moves to the locking area, thereby locking the locking shaft component in the locking area and locking the battery pack onto the locking mechanism. When the locking component is unlocked, the locking shaft component can disengage from the locking area through the first opening. By using the above-described structure and providing the first opening, the locking and unlocking of the locking shaft component is facilitated, improving the efficiency of battery pack installation and removal and enabling rapid battery pack replacement.

[0012] Preferably, the locking component includes an opening slot, and when the locking mechanism is in the locked state, the locking shaft component abuts against the lower surface of the plurality of opening slots.

[0013] In this solution, the above-mentioned structural form is adopted to achieve the locking of the locking shaft component and the locking component, thereby ensuring that the locking shaft component can be stably locked in the opening slot.

[0014] Preferably, the plurality of opening slots coincide in the extending direction of the locking shaft component, and the plurality of opening slots enclose the locking region, which circumferentially surrounds the outer surface of the locking shaft component.

[0015] In this solution, the above-mentioned structural form is adopted. By circumferentially surrounding the outer surface of the locking shaft component with the locking region, the locking area between the locking shaft component and the locking component is increased, the connection strength between the locking shaft component and the locking component is increased, and the locking region provides circumferential limitation for the locking shaft component, thereby improving the stability and reliability of locking.

[0016] Preferably, the plurality of locking components are arranged opposite to each other on both sides of the locking shaft component;

[0017] Alternatively, multiple locking components may be located on the same side of the locking shaft component and coaxially arranged along the extending direction of the locking shaft component.

[0018] In this design, multiple locking components are arranged opposite each other on both sides of the locking shaft component, resulting in multiple opening slots being arranged opposite each other. This allows the opening slots to form a locking area surrounding the locking shaft component, thereby increasing the locking area between the locking components and the locking shaft component. In addition, the above structural form can also restrict the horizontal displacement of the locking shaft component, further improving the locking stability. With multiple locking components located on the same side of the locking shaft component, the contact area between the locking shaft component and the opening slots is increased in the axial direction of the locking shaft component, increasing the connection strength between the locking components and the locking shaft component, improving the stability and reliability of the locking. Furthermore, having multiple locking components on the same side occupies less space in the circumferential direction of the locking shaft component.

[0019] Preferably, when the locking mechanism is in the unlocked state, the plurality of locking components and the first opening at least partially overlap in the extension direction of the locking shaft component.

[0020] In this solution, the above-mentioned structure is adopted. When the locking mechanism is in the unlocked state, part of the locking component is located in the first opening. After the locking shaft component enters the first opening, it can push the part of the locking component located in the first opening to drive the locking component to rotate. This allows the locking area to circumferentially surround the outer surface of the locking shaft component, thereby locking the locking shaft component in the locking area.

[0021] Preferably, the locking mechanism further includes a stop component, which is rotatably connected within the housing of the locking mechanism;

[0022] When the locking mechanism is in the locked state, the stop component cooperates with the locking component to restrict the rotation of the locking component and keep the locking component in the locked position.

[0023] When the locking mechanism is in the unlocked state, the stop component and the locking component disengage, so that the locking component rotates to the unlocked position.

[0024] In this solution, the aforementioned structural form is adopted. When the locking mechanism is in the locked state, the movement of the locking component is restricted by the cooperation of the stop component and the locking component, so that the locking component can cooperate stably with the locking shaft component, preventing the locking shaft component from disengaging from the locking mechanism. This improves the stability and reliability of the locking component's locking of the locking shaft component, thereby achieving stable locking of the battery pack. When the locking mechanism is in the unlocked state, the stop component and the locking component disengage, allowing the locking shaft component to disengage from the locking mechanism. This makes locking and unlocking the battery pack more convenient and quick, which helps to improve the efficiency of battery pack installation and removal, and enables rapid battery pack replacement.

[0025] Preferably, the locking component is provided with a first limiting member, and the stopping component is provided with a second limiting member.

[0026] When the locking mechanism is in the locked state, the first limiting member and the second limiting member cooperate with each other;

[0027] When the locking mechanism is in the unlocked state, the first limiting member and the second limiting member are disengaged.

[0028] In this solution, the above-mentioned structural form is adopted, and the stable cooperation between the locking component and the stopping component is achieved through the cooperation of the first limiting component and the second limiting component, thereby ensuring the reliability of the locking mechanism in locking the locking shaft component.

[0029] Preferably, when the locking mechanism is in the locked state, the first limiting member and the second limiting member are engaged.

[0030] In this solution, the above-mentioned structural form can ensure the stable cooperation between the stop component and the locking component. Thus, the locking shaft component can be stably locked in the locking area through the stop component, thereby ensuring the stable locking of the battery pack.

[0031] Preferably, the locking mechanism further includes a first reset member, which is disposed between the locking component and the housing of the locking mechanism; the first reset member is used to act on the locking component to rotate it to the unlocked position when the locking mechanism is in the unlocked state.

[0032] And / or, the locking mechanism further includes a second reset member disposed between the stop member and the housing of the locking mechanism; the second reset member acts on the stop member to move it from a position disengaged from the locking mechanism to a position engaging with the locking mechanism.

[0033] In this solution, the above-mentioned structure is adopted. When the locking mechanism is in the unlocked state, the first and second limiting members disengage, and the locking component rotates to the unlocked position under the drive of the first reset member. This facilitates the entry and exit of the locking shaft component from the first opening, improving the reset efficiency and unlocking efficiency. When the locking mechanism changes from the unlocked state to the locked state, the stop component moves under the drive of the second reset member, so that the first and second limiting members cooperate, thereby locking the locking shaft component in the locking area and improving the locking efficiency.

[0034] Preferably, the first reset member and / or the second reset member are torsion springs.

[0035] In this solution, the above-mentioned structural form can be used to provide restoring force through a torsion spring, thereby achieving rapid locking and unlocking.

[0036] Preferably, the housing of the locking mechanism is provided with a third limiting member, which cooperates with the stop member to limit the movement range of the stop member;

[0037] And / or, a fourth limiting member is provided on the housing of the locking mechanism, the fourth limiting member cooperating with the locking component to limit the movement range of the locking component.

[0038] In this solution, the aforementioned structural form is adopted. The movement range of the stopping component is limited by the third limiting member, thereby limiting the movement range of the locking component by limiting the stopping component. This prevents the stopping component from displacing too much and failing to cooperate with the locking component, thus ensuring normal locking and improving the stability and reliability of the locking shaft component. The fourth limiting member prevents the locking component from colliding with the housing and causing damage, thereby extending the service life of the locking component.

[0039] Preferably, the third limiting member includes a limiting groove, and the stop member also includes a protrusion that moves within the limiting groove.

[0040] In this solution, the above-mentioned structural form is adopted. Through the cooperation of the protrusion and the limiting groove, the housing limits the stop component, preventing the stop component from rotating too much and failing to cooperate with the locking component.

[0041] Preferably, the locking mechanism further includes an unlocking component, which cooperates with the unlocking mechanism of the battery swapping equipment and acts on the locking component and / or the stop component to rotate the locking component from the locked position to the unlocked position.

[0042] In this solution, the above-mentioned structural form is adopted. External force is applied to the locking component and / or the stop component through the unlocking component, causing the locking component to rotate to the unlock position, thereby disengaging the locking shaft component from the locking component and unlocking the battery pack. This solution features convenient unlocking.

[0043] Preferably, the unlocking component includes a first connector and an unlocking part, one end of the first connector is rotatably connected to the stop component, and the other end of the first connector is movably connected to the unlocking part, so that the first connector generates a horizontal displacement on the unlocking part.

[0044] In this design, the aforementioned structure is used. An external force pushes the unlocking part upward, causing it to move upward. Driven by the unlocking part, the first connecting member rotates the stopping member, allowing it to move away from the locking member. This allows the first limiting member to disengage from the second limiting member, thus unlocking the locking mechanism. The end of the first connecting member connected to the unlocking part experiences horizontal displacement to prevent the first connecting member from jamming with the unlocking part.

[0045] Preferably, the unlocking part includes an unlocking member and a second connecting member, the second connecting member being connected to the unlocking member, the second connecting member extending in a horizontal direction, and the first connecting member being sleeved on the second connecting member.

[0046] In this solution, a structure in which the first connector is fitted onto the second connector is adopted to achieve a movable connection between the first connector and the unlocking part that allows for relative horizontal displacement, thereby preventing the first connector and the unlocking part from getting stuck.

[0047] Preferably, the unlocking component includes a first unlocking body and a second unlocking body, the second unlocking body extends from the first unlocking body toward the first connector, the two ends of the second connector are respectively connected to the two second unlocking bodies, and the first connector is disposed between the two second unlocking bodies.

[0048] In this solution, the above-mentioned structural form is adopted. The first connector is disposed between the second unlocking bodies. The first connector can be limited by the second unlocking bodies to prevent the first connector from falling off the second connector.

[0049] Preferably, the unlocking mechanism further includes a guide portion that cooperates with the unlocking member to restrict the movement direction of the unlocking member.

[0050] In this solution, the above-mentioned structural form is adopted, which allows the unlocking component to move stably along the extension direction of the guide portion.

[0051] Preferably, the guide portion is sleeved on the unlocking member, the inner wall of the guide portion is provided with a locking portion, and the outer wall of the unlocking member is provided with a mating portion, the locking portion engaging with the mating portion.

[0052] In this solution, the above-mentioned structural form is adopted, and the movement direction of the unlocking part is restricted by the engagement of the locking part and the mating part, thereby improving the reliability of locking.

[0053] Preferably, the number of the unlocking component is one, and the plurality of locking components are connected to the unlocking component;

[0054] Alternatively, there may be multiple unlocking components, with each of the multiple locking components connected to a corresponding unlocking component.

[0055] In this solution, the above-mentioned structural form is adopted, with multiple locking components connected to one unlocking component, which improves the compactness of the structure and reduces the cost of use; the one-to-one connection between multiple locking components and multiple unlocking components ensures the reliability and stability of unlocking.

[0056] The present invention also discloses an electric vehicle, which includes the locking mechanism described above.

[0057] In this solution, the above-mentioned structural form is adopted, and the locking mechanism is applied to electric vehicles. At least two locking components cooperate with the same locking shaft component, so that the battery pack is stably locked to the locking mechanism. That is, by using multiple locking components, the cooperation area between the locking components and the locking shaft component is increased, which improves the structural strength and load-bearing capacity of the locking mechanism. It can be applied to heavier battery packs, improves the stability and reliability of locking of the locking shaft component, and thus improves the stability and reliability of locking the battery pack to the locking mechanism.

[0058] Preferably, the electric vehicle is an electric truck.

[0059] In this solution, the above-mentioned structural form is adopted. Since electric trucks have a large capacity requirement for battery packs, the battery packs of electric trucks are generally heavy. The locking axle component needs higher support strength. By applying the above-mentioned locking component to electric trucks, the connection strength, stability and safety between the locking axle component and the locking component are improved by increasing the locking area.

[0060] The positive and progressive effects of this invention are as follows:

[0061] By using at least two locking components in conjunction with the same locking shaft component, the battery pack is stably locked to the locking mechanism. In other words, by using multiple locking components, the contact area between the locking components and the locking shaft component is increased, thereby improving the structural strength and load-bearing capacity of the locking mechanism. This makes it suitable for heavier battery packs, improves the stability and reliability of the locking shaft component, and thus improves the stability and reliability of the battery pack being locked to the locking mechanism.

[0104] Locking shaft component 3 Detailed Implementation

[0105] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0106] This embodiment discloses a locking mechanism 1 to solve the problem that the structural strength and load-bearing capacity of the locking mechanism 1 are poor, resulting in poor locking stability of the battery pack 2.

[0107] like Figures 1 to 14 As shown, the locking mechanism 1 includes at least two locking components 11, which cooperate with the same locking shaft component 3 on the battery pack 2 to lock the battery pack 2. Specifically, the locking mechanism 1 is mounted on the electric vehicle 1000, and the locking shaft component 3 is mounted on the battery pack 2. The locking shaft component 3 cooperates with the locking components 11 to lock the battery pack 2 onto the electric vehicle 1000. This can also be understood as follows: by having at least two locking components 11 cooperate with the same locking shaft component 3, the battery pack 2 is stably locked to the locking mechanism 1; that is, by using multiple locking components 11, the cooperation area between the locking components 11 and the locking shaft component 3 is increased, improving the structural strength and load-bearing capacity of the locking mechanism 1, making it suitable for heavier battery packs, and improving the stability and reliability of the locking of the locking shaft component 3, thereby improving the stability and reliability of the battery pack 2 being locked to the locking mechanism 1.

[0108] Please see Figure 4To understand this, when the locking mechanism 1 is in the locked state, the multiple locking components 11 at least partially overlap in the extending direction of the locking shaft component 3, and the locking shaft component 3 is locked at the overlapping position of the multiple locking components 11. Specifically, the overlapping position is at least located below the locking shaft component 3, so that the locking shaft component 3 can be stably locked at the overlapping position of the multiple locking components 11, increasing the locking area between the locking shaft component 3 and the locking components 11, and improving the stability and reliability of the locking of the locking shaft component 3.

[0109] In practical use, the locking shaft component 3 moves vertically and locks or unlocks to the locking mechanism 1. During the locking or unlocking process of the battery pack 2, the battery pack 2 only needs to move vertically relative to the locking mechanism 1, without needing to adjust the battery pack 2 in other directions (such as the front-rear direction of the electric vehicle). The battery pack 2 moves vertically upward to lock the locking shaft component 3 to the locking component 11. When unlocking, the locking shaft component 3 can disengage from the locking component 11 vertically, making the locking and unlocking of the battery pack 2 convenient and quick, which helps to improve the efficiency of battery pack 2 installation and removal, and enables rapid replacement of the battery pack 2. The locking shaft component 3 is installed on the side wall of the battery pack 2 along the width and / or length direction, and the first end of the locking shaft component 3 near the battery pack 2 is inserted into the battery pack 2 and exerts a force on the battery pack 2. Preferably, the locking shaft component 3 is installed on the side wall of the battery pack 2 along the length and width directions, which can improve the reliability and stability of the connection between the battery pack 2 and the electric vehicle 1000.

[0110] like Figure 7 As shown, the locking mechanism 1 has a first opening 17. When the locking mechanism 1 is in the unlocked state, the locking shaft component 3 enters or leaves the first opening 17 vertically. When the locking mechanism 1 is in the locked state, multiple locking components 11 form a locking area connected to the first opening 17 to lock the locking shaft component 3 within the locking area. Specifically, when the locking component 11 needs to be locked to the locking mechanism 1, the locking shaft component 3 enters the locking component 11 from the first opening 17 and moves down to the locking area, so that the locking shaft component 3 is locked within the locking area, thereby allowing the battery pack 2 to be locked onto the locking mechanism 1. When the locking component 11 is unlocked, the locking shaft component 3 can disengage from the locking area through the first opening 17. By adopting the above structure and providing the first opening 17, the locking and unlocking of the locking shaft component 3 is facilitated, the efficiency of battery pack 2 installation and removal is improved, and the rapid replacement of battery pack 2 is facilitated.

[0111] When unlocking the battery pack 2, the locking shaft component 3 can disengage from the locking area under the force of the battery pack 2 and its own gravity, or the locking shaft component 3 can disengage from the locking area by a force applied externally to the battery swapping device. In other embodiments, the locking shaft component 3 may also disengage from the locking area in other ways, which are not limited here.

[0112] like Figures 4-9 As shown, the locking component 11 includes an opening groove 111. When the locking mechanism 1 is in the locked state, the locking shaft component 3 abuts against the lower surface of the plurality of opening grooves 111. Specifically, the lower ends of the opening grooves 111 at least partially overlap in the extending direction of the locking shaft component 3, so as to form a locking area on the lower surface of the opening grooves 111, and the locking shaft component 3 abuts against the locking area. Preferably, the lower surfaces of the plurality of opening grooves 111 are located on the same horizontal plane in the extending direction of the locking shaft component 3, so that the lower surface of each opening groove 111 can contact the locking shaft component 3, thereby increasing the locking area between the locking shaft component 3 and the opening grooves 111 and improving the stability and reliability of the locking of the locking shaft component 3. By adopting the above structural form, the locking of the locking shaft component 3 and the locking component 11 is realized, thereby ensuring that the locking shaft component 3 can be stably locked in the opening grooves 111.

[0113] Multiple opening slots 111 overlap in the extending direction of the locking shaft component 3, and the multiple opening slots 111 enclose a locking region, which circumferentially surrounds the outer surface of the locking shaft component 3. This structural configuration allows for circumferential positioning of the locking shaft component 3 and increases the locking area between the locking component 11 and the locking shaft component 3, thereby improving locking stability and reliability. Specifically, the portion of the locking shaft component 3 near the locking component 11 is cylindrical, and the multiple opening slots 111 enclose the locking region, which then surrounds the outer surface of the locking shaft component 3. Preferably, the diameter of the locking region is the same as the cross-sectional diameter of the locking shaft component 3 to further increase the locking area between the locking component 11 and the locking shaft component 3.

[0114] like Figure 4 As shown, in the circumferential direction of the locking shaft component 3, multiple locking components 11 are arranged opposite to each other on both sides of the locking shaft component 3, such that multiple opening slots 111 are arranged opposite to each other. This allows the opening slots 111 to form a locking area surrounding the locking shaft component 3, thereby increasing the locking area between the locking components 11 and the locking shaft component 3. Furthermore, this structural form can also restrict the horizontal displacement of the locking shaft component 3, further improving the locking stability. In this embodiment, there are two locking components 11, arranged opposite to each other on both sides of the locking shaft component 3, with the opening slots 111 of the two locking components circumferentially surrounding the entire outer surface of the locking shaft component 3. In this embodiment, to ensure force balance between the two locking components 11, the two locking components 11 are preferably arranged horizontally symmetrically.

[0115] In other embodiments, in the circumferential direction of the locking shaft component 3, the locking components 11 are located on the same side of the locking shaft component 3 and are coaxially arranged along the extension direction of the locking shaft component 3, and the opening directions of the opening slots 111 of the multiple locking components 11 are the same. Specifically, the locking components 11 are rotatably connected to the housing 15, so that the above structure can be implemented in two ways. In the first embodiment, in the axial direction of the locking shaft component 3, the multiple locking components 11 are located on the same side of the housing 15, which increases the contact area between the locking shaft component 3 and the opening slots 111, improves the stability and reliability of locking, and the multiple locking components 11 located on the same side occupy less space in the circumferential direction of the locking shaft component 3. In the second embodiment, in the axial direction of the locking shaft component 3, the multiple locking components 11 are distributed on different sides of the housing 15, which increases the contact area between the locking shaft component 3 and the opening slots 111, while increasing the support span of the locking shaft component 3, further improving the stability of locking.

[0116] like Figure 7 As shown, when the locking mechanism 1 is in the unlocked state, multiple locking components 11 and the first opening 17 at least partially overlap in the extending direction of the locking shaft component 3. When the locking mechanism 1 is in the unlocked state, some locking components 11 are located within the first opening 17, allowing the locking shaft component 3 to enter the first opening 17 and push the portion of the locking component 11 within the first opening 17 to rotate the locking component 11. This allows the locking area to circumferentially surround the outer surface of the locking shaft component 3, thus locking the locking shaft component 3 within the locking area. In practical use, the upper end of the locking component 11 is located within the first opening 17. When the locking shaft component 3 enters the first opening 17 vertically, the upper surface of the locking shaft component 3 contacts the upper end of the locking component 11. As the locking shaft component 3 continues to move upward, it pushes the upper end of the locking component 11 to rotate the locking component 11 on the housing 15, ultimately achieving the locking area surrounding the outer surface of the locking shaft component 3, thus locking the locking shaft component 3 within the locking area.

[0117] like Figures 4-9As shown, the locking mechanism 1 also includes a stop member 14, and the locking member 11 is rotatably connected to the housing 15 of the locking mechanism 1. When the locking mechanism 1 is in the locked state, the stop member 14 cooperates with the locking member 11 to restrict the rotation of the locking member 11, keeping the locking member 11 in the locked position. That is, the stop member 14 can restrict the movement of the locking member 11, allowing the locking member 11 to cooperate stably with the locking shaft member 3, preventing the locking shaft member 3 from disengaging from the locking mechanism 1, improving the stability and reliability of the locking of the locking member 11 to the locking shaft member 3, thereby achieving stable locking of the battery pack 2. When the locking mechanism 1 is in the unlocked state, the stop member 14 and the locking member 11 disengage, allowing the locking member 11 to rotate to the unlocked position. When the locking mechanism 1 is in the unlocked state, the stop member 14 and the locking member 11 disengage, allowing the locking shaft member 3 to disengage from the locking mechanism 1. This makes locking and unlocking the battery pack 2 more convenient and quick, improving the efficiency of battery pack 2 installation and removal, and facilitating rapid battery pack 2 replacement. Specifically, the number of stop members 14 is equal to the number of locking members 11, and each stop member 14 corresponds to a locking member 11. Each stop member 14 restricts the movement of the locking member 11 that cooperates with it, thereby stably locking the locking shaft member 3 within the locking member 11.

[0118] The locking component 11 is provided with a first limiting member 112, and the stopping component 14 is provided with a second limiting member 141. When the locking mechanism 1 is in the locked state, the first limiting member 112 and the second limiting member 141 cooperate with each other; when the locking mechanism 1 is in the unlocked state, the first limiting member 112 disengages from the second limiting member 141. Specifically, when the locking mechanism 1 is in the unlocked state, the second limiting member 141 disengages from the first limiting member 112, the locking shaft component 3 enters through the first opening 17, and drives the locking component 11 to rotate to the locked position. The second limiting member 141 rotates under the elastic force of the torsion spring. When the second limiting member 141 rotates to cooperate with the first limiting member 112, it stops rotating and restricts the rotation of the locking component 11. At this time, the tray transporting the battery pack 2 detaches from the battery pack 2, and the locking component 11 tends to rotate downwards. However, under the limitation of the second limiting member 141, the locking component 11 cannot rotate, thus allowing the locking shaft component 3 to be stably locked within the locking area. During unlocking, an external force is applied to cause the second limiting member 141 to rotate and disengage from the first limiting member 112, allowing the battery pack 2 to detach from the opening slot 111, achieving unlocking. Using the above structural form, the first limiting member 112 and the second limiting member 141 cooperate to achieve a stable engagement between the locking component 11 and the stopping component 14, thereby ensuring the reliability of the locking mechanism 1 in locking the locking shaft component 3. Using the above structural form, the cooperation of the first limiting member 112 and the second limiting member 141 achieves a stable engagement between the locking component 11 and the stopping component 14, thereby ensuring the reliability of the locking mechanism 1 in locking the locking shaft component 3.

[0119] In this embodiment, when the locking mechanism 1 is in the locked state, the first limiting member 112 and the second limiting member 141 are engaged. This structural form ensures a stable engagement between the stop member 14 and the locking member 11, thereby enabling the locking shaft member 3 to be stably locked in the locking area via the stop member 14, thus ensuring the stable locking of the battery pack 2. In other embodiments, the first limiting member 112 and the second limiting member 141 may also be connected in other ways, which are not limited here.

[0120] In practical use, the first limiting member 112 is a recessed portion provided on the locking member 11, and is formed recessed inward from the outer periphery of the locking member 11; the second limiting member 141 is a first protrusion that matches the recessed portion, and extends protruding from the outer periphery of the stopping member 141 towards the locking member 11. In other embodiments, the first limiting member 112 may also be a first protrusion, and the second limiting member 141 may be a recessed portion; this is not a limitation.

[0121] like Figure 9As shown, the first reset member and the second reset member 16 can have the following implementations. In the first implementation, the locking mechanism 1 further includes a first reset member, which is disposed between the locking member 11 and the housing 15 of the locking mechanism 1; the first reset member is used to act on the locking member 11 to rotate it to the unlocked position when the locking mechanism 1 is in the unlocked state. In the second implementation, the locking mechanism 1 further includes a second reset member 16, which is disposed between the stop member 14 and the housing 15 of the locking mechanism 1; the second reset member 16 acts on the stop member 14 to move it from a position disengaged from the locking mechanism 1 to a position cooperating with the locking mechanism 1. In a third embodiment, the locking mechanism 1 further includes a first reset member disposed between the locking member 11 and the housing 15 of the locking mechanism 1. The first reset member is used to act on the locking member 11 to rotate it to the unlocked position when the locking mechanism 1 is in the unlocked state. The locking mechanism 1 also includes a second reset member 16 disposed between the stop member 14 and the housing 15 of the locking mechanism 1. The second reset member 16 acts on the stop member 14 to move it from a position disengaged from the locking mechanism 1 to a position engaged with the locking mechanism 1. Preferably, the locking mechanism 1 further includes a first reset member disposed between the locking member 11 and the housing 15 of the locking mechanism 1; the first reset member is used to act on the locking member 11 to rotate it to the unlocked position when the locking mechanism 1 is in the unlocked state, and the locking mechanism 1 further includes a second reset member 16 disposed between the stop member 14 and the housing 15 of the locking mechanism 1; the second reset member 16 acts on the stop member 14 to move it from a position disengaged from the locking mechanism 1 to a position engaged with the locking mechanism 1. Specifically, when the locking mechanism 1 is in the unlocked state, the first limiting member 112 and the second limiting member 141 disengage, and the locking component 11 rotates to the unlocked position under the drive of the first reset member, thereby facilitating the entry or exit of the locking shaft component 3 into or out of the first opening 17 and improving the reset efficiency and unlocking efficiency. When the locking mechanism 1 changes from the unlocked state to the locked state, the stop component 14 moves under the drive of the second reset member 16, so that the first limiting member 112 and the second limiting member 141 cooperate, thereby locking the locking shaft component 3 in the locking area and improving the locking efficiency. In this embodiment, the first reset member and the second reset member 16 are torsion springs, so that the torsion springs can provide a restoring force to achieve rapid locking and unlocking. In other embodiments, the type of the first reset member and the second reset member 16 is not limited.

[0122] like Figures 4-9As shown, the housing 15 of the locking mechanism 1 is provided with a third limiting member 151 and a fourth limiting member 152, and the third limiting member 151 and the fourth limiting member 152 can have the following embodiments. In a first embodiment, the third limiting member 151 cooperates with the stop member 14 to limit the movement range of the stop member 14; in a second embodiment, the fourth limiting member 152 cooperates with the locking member 11 to limit the movement range of the locking member 11; in a third embodiment, the third limiting member 151 cooperates with the stop member 14 to limit the movement range of the stop member 14, and the fourth limiting member 152 cooperates with the locking member 11 to limit the movement range of the locking member 11. Preferably, the third limiting member 151 cooperates with the stop member 14 to limit the movement range of the stop member 14, and the fourth limiting member 152 cooperates with the locking member 11 to limit the movement range of the locking member 11. With the above-described structure, the movement range of the stop member 14 can be limited by the third limiting member 151. This limits the movement range of the locking member 11, preventing excessive displacement of the stop member 14 and ensuring proper engagement with the locking member 11. This, in turn, guarantees normal locking and improves the stability and reliability of the locking mechanism 3. The fourth limiting member 152 prevents the locking member 11 from colliding with the housing 15 and causing damage, thus extending the service life of the locking member 11.

[0123] The third limiting member 151 includes a limiting groove, and the stop member 14 also includes a protrusion 142 that moves within the limiting groove. Using this structure, the cooperation between the protrusion 142 and the limiting groove achieves the limiting of the stop member 14 by the housing 15, preventing the stop member 14 from rotating too much and failing to cooperate with the locking member 11. In other embodiments, the third limiting member 151 may also take other forms, and the stop member 14 may also include other components that cooperate with the third limiting member 151; this is not limited here.

[0124] The locking mechanism 1 also includes an unlocking component 12. The locking component 11 is used to cooperate with the unlocking mechanism of the battery swapping equipment. The locking component 11 can function in several ways: firstly, the locking component 11 acts on itself; secondly, the locking component 11 acts on the stop component 14; and thirdly, the locking component 11 acts on both itself and the stop component 14. With the above structure, the locking component 11 can be rotated from the locked position to the unlocked position. Preferably, external force acts on the stop component 14 through the unlocking component 12, and the stop component 14 causes the locking component 11 to rotate to the unlocked position, allowing the locking shaft component 3 to disengage from the locking component 11 and unlocking the battery pack 2, which is convenient for unlocking.

[0125] In this embodiment, there are two unlocking components 12, and they are connected one-to-one with two stopping components 14.

[0126] The unlocking component 12 includes a first connector 121 and an unlocking part 122. One end of the first connector 121 is rotatably connected to the stop component 14, and the other end of the first connector 121 is movably connected to the unlocking part 122, so that the first connector 121 generates a horizontal displacement on the unlocking part 122. With this structure, an external force pushes the unlocking part 122 upwards, causing it to move upwards. Under the influence of the unlocking part 122, the first connector 121 drives the stop component 14 to rotate, thereby allowing the stop component 14 to move away from the locking component 11, allowing the first limiting member 112 to disengage from the second limiting member 141, thus unlocking the locking mechanism 1. The horizontal displacement at the end of the first connector 121 connected to the unlocking part 122 prevents the first connector 121 from jamming with the unlocking part 122.

[0127] The unlocking part 122 includes an unlocking member 1221 and a second connecting member 1222. The second connecting member 1222 is connected to the unlocking member 1221 and extends horizontally. The first connecting member 121 is sleeved on the second connecting member 1222. By using the form of the first connecting member 121 sleeved on the second connecting member 1222, a movable connection between the first connecting member 121 and the unlocking part 122, which allows for relative horizontal displacement, is achieved to prevent the first connecting member 121 from getting stuck with the unlocking part 122. Specifically, the unlocking member 1221 includes a first unlocking body 12212 and a second unlocking body 12211. The second unlocking body 12211 extends from the first unlocking body 12212 towards the first connecting member 121. Both ends of the second connecting member 1222 are respectively connected to the two second unlocking bodies 12211, and the first connecting member 121 is disposed between the two second unlocking bodies 12211. With the above-described structure, the first connector 121 is disposed between the second unlocking bodies 12211, and the second unlocking bodies 12211 can limit the first connector 121 to prevent it from falling off the second connector 1222. In actual use, the first unlocking body 12212 and the second unlocking body 12211 are integrally formed to improve the strength of the unlocking part 122.

[0128] The unlocking mechanism also includes a guide portion 13, which cooperates with the unlocking member 1221 to restrict the movement direction of the unlocking member 1221. This structural configuration allows the unlocking member 1221 to move stably along the extension direction of the guide portion 13.

[0129] Please see Figure 10To understand the structure, the guide portion 13 is fitted onto the unlocking member 1221. The inner wall of the guide portion 13 has a locking portion 131, and the outer wall of the unlocking member 1221 has a mating portion 12213. The locking portion 131 engages with the mating portion 12213. Specifically, the guide portion 13 has a guide hole, and the mating portion 12213 is located on the outer wall of the first unlocking body 12212. The first unlocking body 12212 is located within the guide hole, and its outer wall fits against the inner wall of the guide hole, thus achieving a sliding connection between the first unlocking body 12212 and the guide hole. One end of the second unlocking body 12211 extends into the guide hole and connects to the first unlocking body 12212, while the other end extends out of the guide hole and connects to the first connecting member 121. Using this structure, the engagement of the locking portion 131 and the mating portion 12213 restricts the movement direction of the unlocking member 1221, thereby improving the reliability of the locking mechanism. In other embodiments, a guide hole may be formed on the first unlocking body 12212, and the guide portion 13 extends into the guide hole, so that the outer wall of the guide portion 13 fits against the inner wall of the guide hole. In actual use, the engaging portion 131 extends in the same direction as the guide hole, and multiple engaging portions 131 are circumferentially spaced around the inner wall of the guide hole. The mating portion 12213 and the engaging portion 131 are matched one-to-one, which improves the stability of the movement of the unlocking member 1221.

[0130] In this embodiment, the engaging portion 131 is a second protrusion, and the mating portion 12213 is a recess that matches the second protrusion; in other embodiments, the engaging portion 131 is a recess, and the mating portion is a second protrusion that matches the recess. Furthermore, in this embodiment, there are two engaging portions 131, symmetrically arranged on both sides of the guide hole.

[0131] In practical use, the engaging part and the inner wall of the guide hole are integrally formed, which improves the strength of the guide part 13. The first unlocking body 12212 is recessed inward to form the mating part 12213.

[0132] In this embodiment, as Figure 12 and Figure 13 As shown, an electric vehicle 1000 is equipped with a quick-change bracket 100, on which one or more battery packs 2 are mounted. A locking mechanism 1 is provided on the quick-change bracket 100. Only one locking mechanism 1 is provided in the extending direction of each locking shaft component 3. The locking mechanism 1 cooperates with the locking shaft component 3 to lock the battery pack 2 to the electric vehicle 1000.

[0133] In this embodiment, a receiving groove can be formed at the bottom of the quick-change bracket 100, and the locking mechanism 1 is disposed in the receiving groove. The housing 15 of the locking mechanism 1 is fixedly connected to the side wall of the quick-change bracket 100, and the guide portion 13 is also fixedly connected to the side wall of the quick-change bracket 100. In other optional embodiments, the housing 15 of the locking mechanism 1 and the guide portion 13 can also be disposed at other locations of the quick-change bracket 100, or disposed on other structures of the electric vehicle 1000.

[0134] Please see Figure 11 and Figure 14 To understand this, a through hole 21 is provided on the battery pack 2. During unlocking, the unlocking rod extends into the guide hole, allowing the unlocking member 1221 to slide upward within the guide portion 13. Driven by the unlocking member 12, the first limiting member 112 disengages from the second limiting member 141, and the locking member 11 rotates, allowing the locking shaft member 3 to disengage from the opening slot 111, ultimately achieving unlocking.

[0135] In practical use, the through hole 21 is formed on the limiting structure of the battery pack 2. In other embodiments, the position of the through hole 21 is not limited.

[0136] The number of unlocking components 12 is multiple, with each locking component 11 connected to one unlocking component 12 in a one-to-one correspondence, ensuring the reliability and stability of unlocking. In other embodiments, the number of unlocking components 12 is one, with multiple locking components 11 connected to the unlocking component 12. Synchronous unlocking of multiple locking components 11 is achieved through a single unlocking component 12, resulting in high unlocking efficiency, high stability, improved structural compactness, and reduced usage costs. Preferably, the unlocking components 12 of the multiple locking components 11 are interconnected, achieving synchronous unlocking of multiple locking components 11 through a single unlocking component 12, resulting in high unlocking efficiency and low cost.

[0137] In this embodiment, there are two unlocking components 12, and they are connected one-to-one with the two second locking parts 122.

[0138] In practical implementation, when the battery pack 2 is not locked to the locking mechanism 1, the second limiting member 141 disengages from the first limiting member 112. The battery pack 2 drives the locking shaft component 3 into the opening slot 111, and drives the locking component 11 to rotate to the locked position. At this time, the stop component 14 rotates, and the second limiting member 141 and the first limiting member 112 engage with each other, thereby restricting the rotation of the locking component 11. At this time, the tray transporting the battery pack 2 disengages from the battery pack 2, and the locking component 11 tends to rotate downwards. At this time, the second limiting member 141 restricts the rotation of the locking component 11, making it impossible for the locking component 11 to rotate, thereby allowing the locking shaft component 3 to be stably locked in the locking area. When unlocking, an external force is applied to the unlocking component 12, and the unlocking component 1221 can slide upwards within the guide portion 13. Driven by the unlocking component 12, the first limiting member 112 disengages from the second limiting member 141, and the locking component 110 rotates, allowing the locking shaft component 3 to disengage from the opening slot 111, thus unlocking the device. With this structure, the second limiting member 141 and the first limiting member 112 cooperate to achieve a stable engagement between the locking component 11 and the stop component 14, thereby ensuring the reliability of the locking component 11 in locking the locking shaft component 3.

[0139] like Figure 15 As shown, this embodiment also provides an electric vehicle 1000, which includes a locking mechanism 1. One or more battery packs 2 are mounted on the electric vehicle 1000 via the locking mechanism 1. By adopting the above-described structure and applying the locking mechanism 1 to the electric vehicle 1000, at least two locking components 11 can cooperate with the same locking shaft component 3, achieving stable locking of the battery pack 2 to the locking mechanism 1. That is, by using multiple locking components 11, the cooperation area between the locking components 11 and the locking shaft component 3 is increased, improving the structural strength and load-bearing capacity of the locking mechanism 1. This allows it to be applied to heavier battery packs 2, improving the stability and reliability of locking by the locking shaft component 3, and thus improving the stability and reliability of locking the battery pack 2 to the locking mechanism 1.

[0140] Electric vehicle 1000 is an electric truck. Using the above-described structure, because electric trucks have a large capacity requirement for the battery pack 2, the battery pack 2 of an electric truck is generally heavy. Therefore, the locking axle component 3 needs higher support strength. Applying the aforementioned locking component 11 to the electric truck increases the connection strength, stability, and safety between the locking axle component 3 and the locking component 11 by increasing the locking area.

[0141] In other alternative embodiments, the electric vehicle 1000 can also be other types of vehicles such as passenger cars. The above structure can improve the structural strength and load-bearing capacity of the locking mechanism 1, and improve the stability and reliability of the connection between the battery pack 2 and the electric vehicle 1000.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
