DETAILED DESCRIPTION

[0044] In the description of the present invention, 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 the present invention can be understood according to specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] In some embodiments of the present invention, a battery-swap electric vehicle is proposed, which includes a vehicle body, a battery compartment 2, a battery 3, a battery drive device, a battery locking mechanism, etc. The battery compartment 2 is arranged on the vehicle chassis. Figures 1 to 6 The battery 3 is placed in the battery compartment 2, and the battery driving device is used to drive the battery 3 in and out of the battery compartment 2. The existing technology can be used, which is not shown in the figure; the battery locking mechanism is used to lock the battery 3 after the battery 3 enters the battery compartment 2 and unlock the battery 3 when the battery 3 leaves the battery compartment 2. Figure 1 and Figure 2 In the figure, the direction indicated by arrow I is the direction in which the battery 3 enters the compartment, and the direction indicated by arrow II is the direction in which the battery 3 exits the compartment.

[0047] Reference Figures 7 to 12 , while combining Figures 1 to 6 In some embodiments of the present invention, the battery locking mechanism includes a locking driving component 100 , a pressing component 200 , a locking assembly 300 and an elastic component 400 .

[0048] The locking drive component 100 has a telescopic output end 110 , that is, the action of the telescopic output end 110 is a telescopic action, that is, extending or retracting.

[0049] The squeezing component 200 is connected to the telescopic output end 110 of the locking driving component 100 , and extends or retracts along with the telescopic output end 110 .

[0050] The locking assembly 300 includes a locking component 310 and a fixing seat 320, and the locking component 310 is rotatably connected to the fixing seat 320. The locking component 310 has an inclined portion 311 and a locking portion 312. The inclined portion 311 refers to a surface that is oblique to the telescopic direction of the telescopic output end 110, so that the extrusion component 200 can contact the inclined portion 311 when the telescopic output end 110 drives the extrusion component 200 to extend or retract.

[0051] The elastic component 400 is arranged between the locking component 310 and the fixing seat 320, and is used to apply an elastic force to the locking component 310 to drive the inclined portion 311 of the locking component 310 to maintain contact and abutment with the extrusion component 200 during the locking and unlocking process, that is, the elastic force applied by the elastic component 400 to the locking component 310 makes the locking component 310 have a tendency to rotate toward the side where the extrusion component 200 is located.

[0052] When the telescopic output end 110 is extended or retracted, the pressing component 200 is driven to move along the inclined surface 311 of the locking component 310 and press the locking component 310 to make it rotate, so that the locking portion 312 thereof can press and lock the battery 3 .

[0053] Take the example of the telescopic output end 110 driving the squeezing component 200 to extend to achieve squeezing and locking the battery 3. Specifically, the inclined portion 311 faces the side where the locking drive component 100 is located. When the locking drive component 100 is actuated to extend the telescopic output end 110, the telescopic output end 110 drives the squeezing component 200 to extend. When the squeezing component 200 contacts the inclined portion 311, as the squeezing component 200 continues to extend and move along the inclined portion 311, due to the inclination of the inclined portion 311, the squeezing component 200 will squeeze the locking component 310, driving the locking component 310 to rotate toward the side where the battery 3 is located. When the locking component 310 rotates to abut against the battery 3, squeezing and locking the battery 3 is achieved. During this process, the elastic component 400 stores energy.

[0054] When unlocking, the locking drive component 100 is actuated to retract the telescopic output end 110, thereby driving the squeezing component 200 to retract and gradually losing the squeezing force on the locking component 310. The locking component 310 is gradually reset under the elastic force of the elastic component 400 and rotates away from the battery 3 until it is separated from the battery 3, thereby unlocking the battery 3.

[0055] The specific structure and working principle of the battery locking mechanism of the utility model are described in detail below through two specific embodiments.

[0056] Embodiment 1: For the sake of distinction, the battery locking mechanism in this embodiment is referred to as the battery side locking mechanism 1 .

[0057] like Figures 1 to 4 , Figures 7 to 9 As shown, the battery side locking mechanism 1 is located entirely on the side of the battery 3, and on the left and right sides of the battery 3 ( Figure 1 , Figure 2 The battery side locking mechanism 1 is provided on both sides of the battery compartment 2 (the width direction of the battery in the middle is the left-right direction), and the battery side locking mechanisms 1 on the left and right sides are symmetrically arranged, and the battery 3 is clamped and locked from the left and right sides of the battery 3 to further improve the locking reliability. Of course, the battery side locking mechanism 1 can also be provided on only one side of the left and right sides of the battery 3, and the other side can be stopped by the corresponding side plate of the battery compartment 2, and the battery 3 is locked together by the battery side locking mechanism 1 on one side and the side plate of the battery compartment 2; in order to improve the locking reliability, a positioning protrusion can also be provided on the battery 3, and a corresponding positioning groove is provided on the battery compartment 2. After the positioning protrusion is aligned with the positioning groove, the battery 3 is squeezed by the battery side locking mechanism 1 on one side, and the battery 3 is locked together in combination with the stopping effect of the side plate of the battery compartment 2.

[0058] like Figures 1 to 4 , Figures 7 to 9As shown, taking the battery side locking mechanism 1 provided on both the left and right sides of the battery 3 as an example, the rotation axis of the locking component 310 is a horizontal axis and is parallel to the telescopic direction of the telescopic output end 110, and the telescopic direction of the telescopic output end 110 is parallel to the direction of the battery 3 entering and exiting the compartment, that is, Figure 1 , Figure 2 The directions indicated by arrows Ⅰ and Ⅱ.

[0059] The locking component 310 also has a planar portion 313 connected to the inclined portion 311. The inclined portion 311 is inclined at a certain angle relative to the planar portion 313. The planar portion 313 is parallel to the telescopic direction of the telescopic output end 110, and the inclined portion 311 and the planar portion 313 are arranged along the telescopic direction of the telescopic output end 110, so that when the telescopic output end 110 drives the extrusion component 200 to extend or retract, the extrusion component 200 can move along the inclined portion 311 to the planar portion 313, or move from the planar portion 313 to the inclined portion 311.

[0060] When the battery side locking mechanism 1 is locked in place, the locking portion 312 of the locking component 310 of the battery side locking mechanism 1 on the left side is fitted and abutted against the left side surface of the battery 3, the plane portion 313 of the locking component 310 is parallel to the left side surface of the battery 3, and the extrusion component 200 is abutted against the plane portion 313, so that the extrusion force of the extrusion component 200 on the locking component 310 is perpendicular to the left side surface of the battery 3; the locking portion 312 of the locking component 310 of the battery side locking mechanism 1 on the right side is fitted and abutted against the right side surface of the battery 3, the plane portion 313 of the locking component 310 is parallel to the right side surface of the battery 3, and the extrusion component 200 is abutted against the plane portion 313, so that the extrusion force of the extrusion component 200 on the locking component 310 is perpendicular to the right side surface of the battery 3; thereby, the battery 3 is clamped between the battery side locking mechanisms 1 on both sides under the vertical extrusion force on the left and right sides to achieve locking.

[0061] By providing the plane portion 313 , the pressing force on the battery 3 in the locked state is perpendicular to the left and right sides thereof, thereby greatly improving the locking reliability.

[0062] Furthermore, the locking component 310 includes a rigid component and an elastic component 316 that are fixedly connected as one. The rigid component can be made of metal or high-strength plastic. Since the inclined portion 311 and the flat portion 313 need to contact and rub with the extrusion component 200 during the locking and unlocking process, the inclined portion 311 and the flat portion 313 are formed on the rigid component, specifically one side of the rigid component, that is, it is also rigid to increase the service life; and the locking portion 312 needs to directly contact the battery 3, so it is formed on the elastic component 316, specifically one side of the elastic component 316, to reduce wear and damage to the battery 3. The elastic component 316 can be made of rubber or other materials with a certain elasticity; the rigid component is provided with a rotating shaft 317 for rotationally connecting with the fixing seat 320, thereby realizing the rotational connection between the locking component 310 and the fixing seat 320.

[0063] The rigid member and the elastic member 316 can be connected by screws or bonded together.

[0064] Since the locking portion 312 fits against the left side or right side of the battery 3 after being locked in place, the plane portion 313 is parallel to the left side or right side of the battery 3, and the extrusion component 200 abuts against the plane portion 313, the plane portion 313 and the locking portion 312 need to be located on a set of opposite sides of the rigid member. Since the inclined portion 311 is connected to the plane portion 313, the inclined portion 311 and the plane portion 313 are located on the same side of the rigid member, and the locking portion 312 is located on the other opposite side of the rigid member.

[0065] like Figure 3 , Figure 4 , Figures 7 to 9 As shown, the inclined portion 311 and the flat portion 313 are located on the same side A of the rigid member, the elastic member 316 is located on the side B of the rigid member, and the locking portion 312 is correspondingly located on the side B of the rigid member. The side A and the side B are a set of opposite sides of the rigid member.

[0066] To facilitate processing and assembly, Figures 7 to 9 As shown, the rigid part can be formed by welding or screwing a plurality of rigid blocks, the inclined portion 311 and the flat portion 313 are formed on one of the first rigid blocks 314, the elastic member 316 is fixedly connected to another second rigid block 315, the rotating shaft 317 is formed on the second rigid block 315, and the first rigid block 314 and the elastic member 316 are located on a set of opposite sides of the second rigid block 315.

[0067] Since the locking part in this embodiment is fitted with the left side or right side of the battery 3, and the length of the left side or right side of the battery 3 is relatively large, in order to improve the locking reliability, the front-to-back dimension of the locking part is also relatively large. Since the locking part 312 is formed on the elastic member 316, the size of the elastic member 316 is relatively large, and since the elastic member 316 itself has a relatively weak structural strength, there is a risk of sagging and deformation under the action of gravity. In order to improve the structural strength of the elastic member 316 and avoid sagging and deformation, the second rigid member is a horizontal L-shaped plate-like member, whose vertical part is fitted and fixedly connected with a vertical side surface of the elastic member 316, and whose horizontal part is fitted and fixedly connected with the top surface of the elastic member 316, so as to increase the contact area and the connection area with the elastic member 316, improve the structural strength of the elastic member 316, and ensure the reliable locking of the locking part 312.

[0068] In this embodiment, the squeezing component 200 is a rubber roller. Of course, it can be a rubber block of other shapes, such as a spherical block, a hemispherical block, an arc block, etc. that contacts the inclined portion 311 and the flat portion 313 with an arc surface. The reason why the rubber material is selected is that during the locking and unlocking process, the squeezing component 200 has to contact and rub against the inclined portion 311 and the flat portion 313 to generate a squeezing force on the locking component 310. The rubber material can increase the friction force, avoid slipping, and also avoid the problems of high noise and high wear of rigid contact.

[0069] In order to make the telescopic movement of the telescopic output end 110 stable and reliable, in this embodiment, Figure 3 , Figure 4 , Figures 7 to 9 As shown, the battery side locking mechanism 1 further includes a mounting seat 500, on which a first guide member 600 is disposed, and the telescopic output end 110 and the extrusion component 200 are connected by a second guide member 700, and the second guide member 700 is slidably guided in cooperation with the first guide member 600, and the sliding direction is parallel to the telescopic direction of the telescopic output end 110. The second guide member 700 is slidably guided in cooperation with the first guide member 600 to guide the telescopic movement of the extrusion component 200 driven by the telescopic output end 110, so that the movement is stable, thereby maintaining reliable contact and abutment with the inclined portion 311 and the plane portion 313.

[0070] At the same time, by providing the mounting seat 500, the first guide member 600 and the second guide member 700, a certain supporting effect can be provided to the telescopic output end 110 and the extrusion component 200, thereby preventing the telescopic output end 110 of the cantilever structure from being deformed by gravity.

[0071] In this embodiment, the first guide member 600 is a guide rail, the second guide member 700 is a slider, the telescopic output end 110 and the extrusion component 200 are both connected to the second guide member 700, and when the telescopic output end 110 is extended or retracted, the slider is driven to slide along the guide rail, thereby driving the extrusion component 200 to slide along the guide rail. Of course, the first guide member 600 and the second guide member 700 can also be other structures that cooperate with each other to achieve sliding guidance, such as a guide column and guide sleeve structure.

[0072] For the locking drive component 100, in the present embodiment, it is an electric cylinder, and of course it can also be a pneumatic cylinder, a hydraulic cylinder, etc., and the telescopic output end 110 is its piston rod; of course, the locking drive component 100 can also use a motor, and the telescopic output end 110 is a ball screw; the locking drive component 100 can also be other drive components, and a corresponding transmission mechanism is set between it and the telescopic output end 110, so as to be able to convert the movement of the locking drive component 100 into the linear motion of the telescopic output end 110.

[0073] The elastic component 400 is a torsion spring in this embodiment, which is sleeved on the rotating shaft 317 of the rigid member, with one end of the torsion spring against the rigid member and the other end against the fixing seat 320. During the locking process, the elastic component 400 is compressed to store energy, and during the unlocking process, the elastic component 400 is released to drive the locking component 310 to reset. Of course, the elastic component 400 can also be an elastic block or a spring, which is arranged between the locking component 310 and the fixing seat 320. During the process of the locking component 310 rotating to lock the battery 3, the elastic component 400 is compressed or pulled to store energy, and is released during unlocking to drive the locking component 310 to reset.

[0074] In this embodiment, the battery side locking mechanism 1 can be arranged on the side of a single battery 3. If the battery compartment 2 is provided with multiple batteries 3, the battery side locking mechanism 1 is correspondingly arranged on the side of each battery 3 to lock each battery 3 respectively; alternatively, the battery side locking mechanism 1 can also be arranged on the side of the joint between two adjacent batteries 3, such as Figures 1 to 4 As shown, a set of battery side locking mechanisms 1 can lock two adjacent batteries 3 at the same time. Figure 1 and Figure 2 Taking three batteries 3 arranged in sequence along the length direction of the battery compartment 2 as an example, two battery side locking mechanisms 1 are respectively arranged on both sides of two joints of the three batteries 3, and a total of four battery side locking mechanisms 1 are arranged.

[0075] Embodiment 2: For the sake of distinction, the battery locking mechanism in this embodiment is referred to as the battery end locking mechanism 4 .

[0076] Reference Figures 10 to 12 , while combining Figure 1 , Figure 2 , Figure 5 and Figure 6, which is different from the first embodiment, in this embodiment, the rotation axis of the locking component 310 is a vertical axis and is perpendicular to the telescopic direction of the telescopic output end 110; when the battery end locking mechanism 4 is locked in place, the locking portion 312 is aligned with the front end surface or the rear end surface of the battery 3 ( Figure 1 , Figure 2 The longitudinal direction of the battery is the front-to-back direction), the inclined surface 311 is parallel to the front end surface or the rear end surface of the battery 3, and the extrusion component 200 is in contact with the inclined surface 311, such as Figure 6 and Fig.11 That is, in this embodiment, during the locking process and after being locked in place, the pressing component 200 is always in contact with the inclined surface 311; the battery end locking mechanism 4 applies a front-to-back pressing force to the battery 3 from the front end surface or the rear end surface of the battery 3 to clamp and lock the battery 3.

[0077] In order to avoid interfering with the battery 3 entering and exiting the battery compartment 2, in the unlocked state, the battery end locking mechanism 4 is entirely located on the side of the battery 3, and the locking component 310 is pressed against the front end face or the rear end face of the battery 3 only in the locked state. The battery end locking mechanism 4 can be provided on both the left and right sides of the battery 3, and the battery end locking mechanism 4 is close to the front end face or the rear end face of the battery 3. The battery end locking mechanisms 4 on the left and right sides are symmetrically arranged, and the battery 3 is clamped and locked from the left and right ends of the front end face (or rear end face) of the battery 3 to further improve the locking reliability. Of course, if the locking reliability requirement is not high, the battery end locking mechanism 4 can also be provided on only one side of the left and right sides of the battery 3.

[0078] In order to ensure the structural strength of the locking component 310 and reduce the wear on the battery 3, the locking component 310 includes a rigid component and an elastic component 316 that are fixed together as one body, the inclined portion 311 is formed on the rigid component, specifically one side of the rigid component, and the locking portion 312 is formed on the elastic component 316, specifically one side of the elastic component 316; the rigid component is provided with a rotating shaft 317 for rotationally connecting with the fixing seat 320.

[0079] To facilitate processing and assembly, Figures 10 to 12 As shown, the rigid member can be formed by welding or screwing a plurality of rigid blocks, the inclined portion 311 is formed on one of the first rigid blocks 314 , and the elastic member 316 is fixedly connected to another second rigid block 315 .

[0080] The structures of the pressing component 200 , the locking driving component 100 , and the elastic component 400 are the same as those in the first embodiment and are not described in detail herein.

[0081] Similarly, the battery end locking mechanism 4 also includes a mounting seat 500, on which a first guide member 600 is provided, and the telescopic output end 110 and the extrusion component 200 are connected by a second guide member 700, and the second guide member 700 is slidably guided with the first guide member 600, and the sliding direction is parallel to the telescopic direction of the telescopic output end 110. The second guide member 700 is slidably guided with the first guide member 600 to guide the telescopic movement of the extrusion component 200 driven by the telescopic output end 110.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
