[0028] To more clearly illustrate the technical solutions of the embodiments of this specification, the following briefly describes the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this specification. Those skilled in the art can apply this specification to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0029] It should be understood that the terms "system," "device," "unit," and / or "module" used herein are a method for distinguishing different components, elements, parts, portions, or assemblies at different levels. However, if other terms can achieve the same purpose, the terms may be replaced by other expressions.

[0030] As used in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not refer to the singular but also include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0031] This specification describes a mounting structure for mounting a battery pack on a new energy vehicle, typically beneath the vehicle chassis. When the battery pack is operating normally, the mounting structure secures it to the vehicle. However, if an abnormality occurs, the mounting structure allows the battery pack to be quickly released from the vehicle chassis, allowing it to be quickly detached.

[0032] This specification discloses a mounting structure, which primarily includes a locking rod, a locking assembly, and a first drive mechanism. This mounting structure can be used to mount a battery pack beneath a vehicle's chassis. The lower end of the locking rod is fixedly connected to the battery pack beneath the vehicle's chassis, and the locking rod is also connected to the locking assembly. The locking rod and the locking assembly have a locked state and a disengaged state. When the locking rod and the locking assembly are in the locked state, the battery pack is fixedly connected to the vehicle's chassis and maintains high stability. When the battery pack experiences an abnormality, the mounting structure, driven by the first drive mechanism, can quickly switch the locking rod and the locking assembly to the disengaged state. The locking rod moves downward under the weight of the battery pack itself, disengaging from the vehicle's chassis. This allows the battery pack to quickly release its fixed connection to the vehicle's chassis, allowing it to quickly detach from the vehicle's chassis. Under the action of inertia, the new energy vehicle will continue to move forward for a distance to avoid the abnormal battery pack, thereby ensuring the safety of those on board.

[0033] See also Figure 1 Some embodiments of this specification provide a mounting structure 100 for mounting a battery pack 200 under a chassis of a new energy vehicle.

[0034] See also Figure 3 The mounting structure 100 includes a locking rod 110, a locking assembly 120 and a first driving mechanism 130. The locking rod 110 and the locking assembly 120 are in a locked state (e.g. Figure 4 as shown) and detached state (as shown Figure 5As shown). One end of the locking rod 110 is connected to the battery pack 200, and a slide groove 114 is provided on the locking rod 110. The locking assembly 120 includes a moving mechanism 121 and a limiting mechanism 122. The moving mechanism 121 moves in the Y direction relative to the vehicle chassis 300. The moving mechanism 121 includes a matching portion, which is movably provided in the slide groove 114. When the moving mechanism 121 drives the matching portion to move out of the slide groove 114 along the first direction, the locking rod 110 is disengaged from the moving mechanism 121. The limiting mechanism 122 is used to limit the matching portion of the moving mechanism 121 in the slide groove 114. The first driving mechanism 130 drives the matching portion of the moving mechanism 121 to move out of the slide groove 114 along the first direction.

[0035] Figure 3 The Z direction may be the direction of gravity, and the plane formed by the X and Y directions may be the horizontal direction perpendicular to the Z direction. When the car is traveling on the ground parallel to the horizontal direction, the locking rod 110 extends along the Z direction. It should be noted that the first direction mentioned above is Figure 3 The opposite direction of the Y direction, the second direction below is Figure 3 In some embodiments, one end of the locking rod 110 (i.e., the lower end of the locking rod 110 extending along the Z direction) is fixedly connected to the battery pack 200, and the locking rod 110 passes through a through hole in the vehicle chassis 300, and the other end of the locking rod 110 (i.e., the upper end of the locking rod 110 extending along the Z direction) cooperates with the locking assembly 120.

[0036] In some embodiments, the locking rod 110 may be a multi-step cylinder with different diameters. Figure 2 、 Figure 3 , the locking rod 110 may include a first-level locking rod 111, a second-level locking rod 112 and a third-level locking rod 113 from top to bottom in the Z direction. The diameters of the first-level locking rod 111, the second-level locking rod 112 and the third-level locking rod 113 gradually increase from top to bottom. The third-level locking rod 113 is fixedly connected to the battery pack 200, which can be any fixed connection method such as welding, riveting or screw connection. The connection method is not limited, and it is only necessary to ensure the stability of the connection between the third-level locking rod 113 and the battery pack 200. The outer diameter of the second-level locking rod 112 matches the inner diameter of the through hole on the automobile chassis 300. In some embodiments, in order for the locking rod 110 to quickly detach from the through hole on the automobile chassis 300, the outer diameter of the second-level locking rod 112 may be slightly smaller than the inner diameter of the through hole. The height of the second-level locking rod 112 in the Z direction may be approximately equal to the thickness of the automobile chassis 300. In some embodiments, when the locking rod 110 and the locking assembly 120 are in a locked state, the third-stage locking rod 113 passes through the through hole and is higher than the upper end surface of the vehicle chassis 300. The third-stage locking rod 113 is used to connect with the locking assembly 120.

[0037] The sliding groove 114 can be provided on the horizontal side of the locking component 120 on the surface of the first-stage locking rod 111. The matching portion of the locking component 120 is movably disposed in the sliding groove 114.

[0038] In some embodiments, see Figure 3 The locking assembly 120 may include a moving mechanism 121 and a limiting mechanism 122. The matching portion of the moving mechanism 121 is movably arranged in the slide groove 114. When the matching portion of the moving mechanism 121 is moved out of the slide groove 114, the locking rod 110 is separated from the moving mechanism 121. The limiting mechanism 122 is used to limit the matching portion of the moving mechanism 121 in the slide groove 114, that is, the connection relationship between the locking rod 110 and the locking assembly 120 is stably maintained in a locked state (such as Figure 4 For more details about the locking assembly 120, see below.

[0039] The first driving mechanism 130 can drive the matching portion of the moving mechanism 121 to move out of the sliding groove 114 along the first direction. Figure 1 、 Figure 7 The first driving mechanism 130 may include a first driving source 131 and a first cable 132. The two ends of the first cable 132 are respectively connected to the output end of the first driving source 131 and the moving mechanism 121. When the first driving source 131 provides tension to the first cable 132, the moving mechanism 121 can be driven to move along the first direction, so that the matching portion of the moving mechanism 121 moves out of the slide groove 114, so that the locking rod 110 is separated from the moving mechanism 121. At this time, the locking rod 110 and the locking assembly 120 are in a disengaged state (such as Figure 5 The first driving source 131 may be a driving motor or a driving cylinder, which is not limited here.

[0040] It should be noted that the mounting structure 100 of the embodiments of this specification can have a variety of relative positions relative to the vehicle chassis 300, but when the locking rod 110 is disengaged from the movable mechanism 121, the battery pack 200 can be separated from the vehicle chassis. For example, the mounting structure can be entirely located below the vehicle chassis 300, with the movable mechanism 121 movably disposed below the vehicle chassis 300, and the locking rod 110 connected to the movable mechanism 121 through the engagement of the slide 114 and the mating portion. When the mating portion of the movable mechanism 121 moves out of the slide 114, the locking rod 110 disengages from the movable mechanism 121, and the locking rod 110 and the battery pack 200 are separated from the vehicle chassis under the action of gravity. For another example, a through hole is provided on the automobile chassis 300, and the movable mechanism 121 is movably provided above the automobile chassis 300. The lower end of the locking rod 110 is connected to the battery pack, and the locking rod 110 passes through the through hole. The slide groove 114 is also located above the automobile chassis 300. Please refer to the relevant instructions below for this connection method.

[0041] In some embodiments, see Figure 3-Figure 5 The locking assembly 120 further includes a first fixing portion 123-1 and an elastic member 124. The first fixing portion 123-1 is fixed relative to the movement of the moving mechanism 121. In some embodiments, the first fixing portion 123-1 can be fixedly connected to the vehicle chassis 300. The elastic member 124 applies a force to the moving mechanism 121 in a second direction, which is opposite to the first direction.

[0042] In some embodiments, the locking assembly 120 may further include a second fixing portion 123-2. The first fixing portion 123-1 is fixedly arranged in the extension direction of the first direction of movement of the moving mechanism 121 (i.e., the opposite direction of the Y direction). The second fixing portion 123-2 is fixedly arranged in the extension direction of the second direction of movement of the moving mechanism 121 (i.e., the Y direction). It can also be understood that the first fixing portion 123-1 and the second fixing portion 123-2 are respectively arranged on the front and rear sides of the moving direction of the moving mechanism 121, for limiting the moving stroke of the moving mechanism 121. Figure 4 As shown, when one end of the moving mechanism 121 is attached to the second fixing portion 123-2, the locking rod 110 and the locking assembly 120 are in a locked state; Figure 5 As shown, when the other end of the moving mechanism 121 is in contact with the first fixing portion 123 - 1 , the locking rod 110 and the locking assembly 120 are in a disengaged state.

[0043] In some embodiments, see Figure 3-Figure 5 , the moving mechanism 121 contacts the first fixing portion 123-1 through the elastic member 124. In some embodiments, as Figure 4 As shown, both ends of the elastic member 124 are fixedly connected to the moving mechanism 121 and the first fixing portion 123-1 respectively. Figure 3-Figure 5 One end of the movable mechanism 121 is fixedly connected to the movable mechanism 121 through the first through hole 123-3 on the first fixed portion 123-1. The elastic member 124 is used to provide a force in the second direction to the movable mechanism 121, driving one end of the movable mechanism 121 to abut against the second fixed portion 123-2, so as to keep the connection relationship between the locking rod 110 and the locking assembly 120 stably maintained in a locked state. In some embodiments, the elastic member 124 can be a structure with elastic force, such as a spring or a rubber body. When the first driving mechanism 130 drives the movable mechanism 121 to move in the second direction through the first cable 132, the elastic member 124 is compressed until the other end of the movable mechanism 121 is attached to the first fixed portion 123-1 (such as Figure 5When the first driving mechanism 130 cancels the driving force, the rebound force of the elastic member 124 drives the moving mechanism 121 to move so that the matching portion of the moving mechanism 121 moves into the sliding groove 114, and one end of the moving mechanism 121 is attached to the second fixing portion 123-2 (as shown). Figure 4 As shown), the stability of the locked state between the locking rod 110 and the locking assembly 120 is further enhanced.

[0044] In some embodiments, the width of the slide groove 114 along the extension direction of the locking rod 110 (i.e., the Z direction) gradually decreases along the second direction. When the matching portion is located at the end of the slide groove 114 with a smaller width, the matching portion can be aligned with at least two opposite sides of the slide groove (e.g., Figure 2 and the upper side and lower side thereof are in contact with each other. In some embodiments, the slide groove 114 is an inclined groove, at least one side of the inclined groove is an inclined surface (relative to the upper surface of the automobile chassis), and the slope of the inclined surface is less than the self-locking slope. Therefore, when the matching portion of the mobile mechanism 121 (such as the first roller below) moves into the slide groove 114, and one end of the mobile mechanism 121 is fitted with the second fixed portion 123-2, a self-locking is formed between the inclined surface of the slide groove 114 and the matching portion of the mobile mechanism 121 (such as the first roller below), effectively increasing the friction coefficient between the slide groove 114 and the matching portion, and ensuring the stability of the locked state between the locking rod 110 and the locking assembly 120. When the first driving mechanism 130 cancels the driving force, the rebound force of the elastic member 124 drives the mobile mechanism 121 to move along the second direction so that the matching portion of the mobile mechanism 121 moves into the slide groove 114, so that the matching portion can be maintained at the end of the slide groove 114 with a smaller width, and the matching portion can be aligned with at least two opposite sides of the slide groove 114 (such as Figure 2 The upper and lower sides of the locking rod 110 and the locking assembly 120 are both in contact with each other, further enhancing the stability of the locked state between the locking rod 110 and the locking assembly 120.

[0045] In some embodiments, see Figure 2 、 Figure 6 In some embodiments, the upper top surface of the chute 114 is a sloped surface, and the lower bottom surface is a plane. In some embodiments, the upper top surface of the chute 114 can be a plane, and the lower bottom surface can be a sloped surface. In some embodiments, the upper top surface and the lower bottom surface of the chute 114 can both be sloped surfaces.

[0046] In some embodiments, see Figure 3-Figure 6 The mating portion includes a first roller 1211, which is rotatably disposed within the chute 114. The first roller 1211 is rotatably connected to the moving mechanism 121. The moving mechanism 121 moves in a first direction, driving the first roller 1211 to roll out of the chute 114. Because the coefficient of rolling friction is lower than that of sliding friction, the first roller 1211 is selected as the mating portion of the moving mechanism 121 that moves within the chute 114.

[0047] In some embodiments, the first roller 1211 may be a bearing. Specifically, the first roller 1211 may be a rolling bearing, the inner ring of which is fixedly connected to the side of the movable mechanism 121 facing the chute 114 via a connecting shaft. The movable mechanism 121 moves in the first direction, causing the outer ring of the first roller 1211 to roll out of the chute 114. The use of a rolling bearing for the first roller 1211 can reduce the coefficient of friction during its movement, allowing the first roller 1211 to quickly disengage from the chute 114 when an abnormality occurs in the battery pack 200.

[0048] In some embodiments, the moving mechanism 121 is provided with at least one second roller 1212. The rolling direction of the at least one second roller 1212 is consistent with the moving direction of the moving mechanism 121. When the moving mechanism 121 moves, the at least one second roller 1212 forms rolling friction with the upper end surface of the vehicle chassis 300, which can effectively reduce the friction coefficient between the mating portion and the vehicle chassis 300.

[0049] In some embodiments, the moving mechanism 121 may be provided with a plurality of second rollers 1212, such as Figure 3-Figure 6 As shown, three second rollers 1212 may be provided on the moving mechanism 121 .

[0050] In some embodiments, the number of the second rollers 1212 on the moving mechanism 121 can be specifically designed according to the size of the second rollers 1212 and the moving stroke of the moving mechanism 121 , and can be 2, 4, or more.

[0051] In some embodiments, see Figure 3-Figure 6 The limiting mechanism 122 includes a pivot 1221 and a limiting member 1222 rotatably mounted on the pivot 1221. The pivot 1221 extends in the Z direction and is fixedly connected to the movable mechanism 121. The limiting member 1222 serves as a safety hook for the movable mechanism 121. When the movable mechanism 121 is locked relative to the slide 114, the limiting member 1222 limits the position of the movable mechanism 121, preventing the movable mechanism 121 from moving due to vibration or other reasons during driving.

[0052] In some embodiments, the mounting structure 100 further includes a second drive mechanism 140, which includes a second drive source 141 and a second cable 142. One end of the second cable 142 is drivingly connected to the output end of the second drive mechanism 140, and the other end of the second cable 142 is fixedly connected to the pull-limiting member 1222. Driven by the second drive source 141, the second cable 142 pulls the limiting member 1222 to rotate about the axis of the pivot 1221, thereby releasing the limit on the movable mechanism 121.

[0053] In some embodiments, see Figure 6A cable fixing hole 1224 is provided at one end of the limiting member 1222 away from the pivot 1221 . The other end of the second cable 142 is fixedly connected to the limiting member 1222 through the cable fixing hole 1224 .

[0054] In some embodiments, a torsion spring 1223 is provided on the pivot 1221. The torsion spring 1223 is sleeved around the pivot 1221, with the axes of the torsion spring 1223 and the pivot 1221 coinciding in the Z direction. When the second drive source 141 stops driving the limiting member 1222, the elastic restoring force of the torsion spring 1223 restores the limiting member 1222 to its position relative to the moving mechanism 121. This further enhances the stability of the locked state between the locking bar 110 and the locking assembly 120.

[0055] Some embodiments of this specification also provide an automobile, comprising a battery pack 200, a chassis 300, a through-hole provided in the chassis 300, and the mounting structure 100 provided in any of the above embodiments. The through-hole in the chassis 300 extends through the chassis 300 in the thickness direction, and the locking rod 110 of the mounting structure 100 passes through the through-hole. The battery pack 200 is disposed below the chassis 300, and the locking assembly 120 of the mounting structure 100 is disposed above the chassis 300. The battery pack 200 is fixedly connected to the lower end of the locking rod 110. Figure 8 In the mounting structure 100 , the locking rod 110 and the locking assembly 120 are in a locked state. Figure 9 In the mounting structure 100, the locking rod 110 and the locking assembly 120 are in a disengaged state. By providing a through hole, the locking assembly 120 of the mounting structure 100 is arranged above the vehicle chassis 300, which can more stably install the battery pack 200.

[0056] In some embodiments, there are multiple mounting structures 100, and multiple mounting structures 100 are arranged in an array on the automobile chassis 300. There are multiple through holes, and multiple through holes are arranged in a one-to-one correspondence with multiple mounting structures 100. In some embodiments, see Figure 8 、 Figure 9 , the number of mounting structures 100 can be six. The six mounting structures 100 are arranged in an array on the automobile chassis 300. In this embodiment, there are also six corresponding first cables 132 and second cables 142. The six first cables 132 are connected to the six moving mechanisms 121 of the six mounting structures 100. The six second cables 142 are connected to the six limiting members 1222 of the six mounting structures 100. In some embodiments, the first driving source 131 can drive the six first cables 132 simultaneously, and the second driving source 141 can drive the six second cables 142 simultaneously.

[0057] When an abnormality occurs in the battery pack 200, the first driving source 131 and the second driving source 141 provide driving force at the same time, and the six second cables 142 drive the six limiting members 1222 to rotate and contact the six limiting members 1222 to limit the corresponding moving mechanisms 121. The six first cables 132 drive the corresponding moving mechanisms 121 to move along the Y direction until the six moving mechanisms 121 are simultaneously disengaged from the corresponding locking rods 110, and the locking rods 110 fall downward under the action of the gravity of the battery pack 200, so as to enable the new energy vehicle to quickly get rid of the abnormal battery pack 200 during driving to ensure the safety of the people in the vehicle.

[0058] The beneficial effects that may be brought about by the embodiments of this specification include but are not limited to: (1) the battery pack is fixed to the chassis of the vehicle by forming a locked state with the locking rod and the locking assembly, and the moving mechanism of the locking assembly is at least partially movable in the slide groove of the locking rod, and the moving mechanism is driven by the first driving mechanism to quickly remove the abnormal battery; (2) a first roller is provided on the moving mechanism, and the rolling friction between the roller and the slide groove reduces the friction coefficient between the moving mechanism and the slide groove, so that the moving mechanism can move quickly relative to the slide groove to quickly remove the abnormal battery; (3) a second roller is also provided on the moving mechanism, and the friction coefficient between the moving mechanism and the fixed part is reduced by the addition of the second roller, further realizing the rapid movement of the moving mechanism relative to the slide groove to quickly remove the abnormal battery; (4) a limiting mechanism is provided on the moving mechanism, which can not only further enhance the stability of the locked state between the locking rod and the locking assembly, but also ensure the installation stability of the battery pack.

[0059] It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects that may be produced may be any one or a combination of the above, or any other possible beneficial effects.
