Those of skill in the art will explicitly and implicitly appreciate that the described embodiments of the application may be combined with other embodiments.

In the present application, a battery refers to a physical module including one or more battery cells to supply electric power. For example, the battery referred to in the present application may include a battery module or a battery pack, or the like. The battery generally includes a case for enclosing one or more battery cells. The case body can prevent liquid or other foreign matters from affecting the charge or discharge of the battery cells.

Alternatively, the battery cell may include a lithium ion secondary battery, a lithium ion primary battery, a lithium sulfur battery, a sodium lithium ion battery, a sodium ion battery, a magnesium ion battery, or the like, which is not limited by the embodiment of the application. The battery cell may be in a cylindrical shape, a flat shape, a rectangular parallelepiped shape, or other shapes, which is not limited in this embodiment of the application. The battery cells are generally classified into three types according to the packaging method: the cylindrical battery cell, the square battery cell and the soft package battery cell are not limited in this embodiment.

To meet different power demands, a battery may include a plurality of battery cells, where the plurality of battery cells may be connected in series or parallel or a series-parallel connection, which refers to a mixture of series and parallel. Optionally, the plurality of battery cells may be connected in series or parallel or in series-parallel to form a battery module, and then the plurality of battery modules are connected in series or parallel or in series-parallel to form a battery. That is, a plurality of battery cells may be directly assembled into a battery, or may be assembled into a battery module first, and the battery module may be assembled into a battery. The battery is further arranged in the electric equipment to provide electric energy for the electric equipment.

In the embodiment of the application, the electric equipment can be a vehicle, the vehicle can be a fuel oil vehicle, a fuel gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle or a range-extending vehicle and the like. The vehicle may have a motor, a controller and a battery, the controller being configured to control the battery to power the motor. For example, a battery may be provided at the bottom or the head or tail of the vehicle. The battery may be used for power supply of the vehicle. In one embodiment of the application, the battery may be used as an operating power source for the vehicle, for the vehicle's circuitry, e.g., for the starting, navigation, and operational power requirements of the vehicle. In another embodiment of the application, the battery may be used not only as an operating power source for the vehicle, but also as a driving power source for the vehicle, instead of or in part instead of fuel oil or natural gas, to provide driving power for the vehicle.

As the vehicle is operated, in which the charge of the battery is gradually reduced, it is required to periodically charge the battery in the vehicle through the charging post in the conventional art so as to ensure that the battery has sufficient charge to maintain the continuous operation of the vehicle. However, since the battery capacity is generally large, each charging time is long, and the user cannot use the vehicle during the long charging time, so that the vehicle using experience of the user is seriously affected.

Currently, many types of vehicle batteries are mounted on the chassis of the vehicle, in which case some of the battery stations are equipped with a vehicle lifting system and a battery exchange device. After a user drives the vehicle into the power exchange station, the vehicle lifting system lifts the vehicle and the user in the vehicle together, and then the power exchange device exchanges the battery positioned on the chassis of the vehicle. In the process, when the vehicle lifting system is directly contacted with a stationary vehicle, the vehicle is impacted, so that the vehicle is rocked, and the experience of a user in the vehicle is affected. In addition, the battery replacement device can push the battery to the chassis of the vehicle no matter the original battery in the vehicle is detached or a new battery is installed in the process of replacing the battery, so that the impact is caused to the vehicle, and the experience of a user in the vehicle can be influenced.

In view of the above, the present application provides a vehicle lifting device, in which an elastic member is provided, and when the vehicle lifting device contacts with a vehicle, the elastic member can absorb impact of the vehicle lifting device on the vehicle, so that the vehicle lifting device contacts with the vehicle more flexibly, and user experience in the vehicle is improved. In addition, when the battery replacement device is used for replacing the battery of the vehicle, the vehicle lifting device can be supported on the vehicle in a whole-course contact manner through the action of the elastic piece, so that the impact of the battery replacement device on the vehicle is reduced, and the user experience in the vehicle is further improved.

The battery rack 101 may include a battery charging compartment and a battery buffering device. The battery may be stored within a battery charging bin so that the battery may be charged. The battery buffer may be used to temporarily store the battery for which the vehicle is replaced.

In addition to the battery rack 101, the power station 100 may also include a stacker 102 and a mobile power change device (not shown in fig. 1). The mobile power exchanging device can transport the battery with the power shortage which is exchanged from the vehicle to the battery buffer device, and the stacker 102 transports the battery with the power shortage in the battery buffer device to the battery rack 101, so that the battery rack 101 charges the battery with the power shortage. In addition, the stacker crane 102 may also transport the full battery on the battery rack 101 to a mobile power exchanging device that moves the full battery to the vehicle and mounts the full battery to the vehicle. The mobile power transfer device may be, for example, a rail guided vehicle (rail guided vehicle, RGV) or an automated guided vehicle (automated guided vehicle, AGV).

The power plant 100 may also include a power conversion platform 200. Fig. 2 shows a schematic representation of a vehicle 1 travelling on a battery exchange platform 200.

When the vehicle 1 is lifted, the mobile power conversion device can be moved to the lower side of the vehicle 1, when the mobile power conversion device is aligned with the battery in the chassis of the vehicle 1, the mobile power conversion device can detach the battery with the power shortage in the vehicle, then the mobile power conversion device moves to the vicinity of the battery buffer device, and the battery with the power shortage is placed in the battery buffer device. The stacker 102 acquires full-power batteries from the battery rack 101 in advance, waits for the mobile battery replacing device at the battery buffering device, and when the mobile battery replacing device stores the full-power batteries in the battery buffering device, the stacker 102 places the full-power batteries in the mobile battery replacing device without batteries, and conveys the full-power batteries in the battery buffering device to the battery rack 101 for charging. Further, the mobile power conversion device obtains the full-power battery to be installed from the stacker 102, and drives the full-power battery to be installed to the lower part of the vehicle 1 again, and loads the battery to be installed into the chassis of the vehicle 1.

Optionally, a locking mechanism is provided in the chassis of the vehicle 1, a locking portion corresponding to the locking mechanism is provided in the battery, and the locking mechanism can be used for locking the locking portion, so that the battery can be mounted on the chassis of the vehicle 1 in a locking manner; correspondingly, the locking structure may also be configured to release the locking of the locking portion, so that the battery may be unlocked and detached from the chassis of the vehicle 1. In the process of disassembling and assembling the battery by the mobile battery changing device, the mobile battery changing device can push the battery upwards to unlock and lock the locking part in the battery and the locking mechanism in the vehicle 1, so that the battery is disassembled and assembled.

After the vehicle 1 completes the power change, the mobile power change device exits the power change platform 200, and the vehicle lifting system 300 may lower the vehicle 1 back to the power change platform 200.

In addition, the frame upright 320 may form a space for accommodating the vehicle 1, in which the vehicle lifting system 300 lifts the vehicle 1.

Alternatively, the vehicle lifting system 300 may include, corresponding to a plurality of the frame uprights 320: a plurality of discrete lifting mechanisms 310, wherein the plurality of lifting mechanisms 310 are arranged in a one-to-one correspondence with the plurality of upright posts. When the vehicle lifting system 300 lifts the vehicle 1, the plurality of lifting mechanisms 310 contact the chassis of the vehicle 1 and provide supporting force to the vehicle 1. Specifically, the lifting of the vehicle 1 is achieved by controlling the lifting of the plurality of lifting mechanisms 310.

Alternatively, in the embodiment of the present application, the lifting mechanism 310 may be driven to lift by the motor 340 and the transmission mechanism 330, and both the motor 340 and the transmission mechanism 330 may be disposed on the frame upright 320.

It can be appreciated that, in the case that the vehicle lifting system 300 includes a plurality of lifting mechanisms 310, each lifting mechanism 310 may be correspondingly provided with a transmission chain 331 and a transmission shaft 332, and the motor 340 is matched with the driving of the plurality of sets of transmission chains 331 and the transmission shafts 332, so that the lifting effect of driving the plurality of lifting mechanisms 310 by one motor 340 to lift the vehicle 1 can be achieved.

Fig. 4 shows a schematic structural diagram of a vehicle lifting device 400 according to an embodiment of the application. Alternatively, in some embodiments, the vehicle lifting device 400 may be one implementation of the lifting mechanism 310 in the vehicle lifting system 300 shown in fig. 3 above. In other embodiments, the vehicle lifting device 400 may not rely on the vehicle lifting system 300 shown in FIG. 3, but may be adapted for lifting vehicles in other situations.

As shown in fig. 4, the vehicle lifting device 400 includes: a lifting arm 410; the supporting block 420 is disposed on the lifting arm 410, and is used for supporting the vehicle 1 (not shown in fig. 4), wherein the lifting arm 410 is used for driving the supporting block 420 to lift the vehicle 1; and an elastic member 430 disposed between the support block 420 and the lifting arm 410, the elastic member 430 being configured to provide an elastic supporting force to the vehicle 1 through the support block 420.

Specifically, in embodiments of the present application, the lifting arm 410 is a rigid structure that may have a greater stiffness and a greater compressive capacity. As an example, as shown in fig. 4, the lifting arm 410 has a plate-like structure as a whole, and the plate-like structure is disposed toward the vehicle 1 when the vehicle lifting device 400 lifts the vehicle 1. The plate-shaped structure is convenient to process, is convenient for installation and arrangement of all parts, and has higher mechanical stability. Alternatively, the lifting arm 410 shown in fig. 4 is L-shaped, and the lifting arm 410 may have any other regular or irregular shape, such as an elongated shape, a T-shape, a semicircular shape, etc., in addition to the L-shape, which is not particularly limited in the embodiment of the present application.

The support block 420 may have a block structure with a regular shape, and as an example, the support block 420 shown in fig. 4 has a hexahedral structure, which has high stability, is convenient to be mounted on the support arm 410, and is also convenient to be adapted to the vehicle 1. Optionally, the area of the supporting surface of the supporting block 420 for supporting the vehicle 1 may be designed according to practical application, and the area of the supporting surface may be smaller than a certain threshold value, so that the supporting block 420 can be adapted to more different types of vehicles 1, and in addition, the area of the supporting surface may be larger than a certain threshold value, so that the supporting block 420 can have a relatively stable supporting effect. In some embodiments, the support blocks 420 may have an area of about 100mm x 100mm to accommodate vehicles 1 compatible with various vehicle models while providing stable support.

Specifically, the location of the support blocks 420 on the lifting arms 410 may be designed according to the actual application requirements. As an example, as shown in fig. 4, a support block 420 may be located at one end of the lifting arm 410. Alternatively, in other examples, the support block 420 is also located in the middle of the lifting arm 410.

In the embodiment of the present application, an elastic member 430 is further provided between the lifting arm 410 and the support block 420, and the elastic member 430 may be used to provide elastic supporting force to the vehicle 1 through the support block 420. In other words, when the vehicle lifting device 400 is used to lift the vehicle 1, the support block 420 does not instantaneously impact the vehicle 1, but elastically acts on the vehicle 1 by means of the elastic member 430.

Alternatively, the elastic member 430 may be any member having elasticity and also having a certain strength. By way of example, the resilient member 430 includes, but is not limited to, a spring member, a rubber member, and the like.

Therefore, according to the technical solution of the embodiment of the present application, the elastic member 430 is disposed between the lifting arm 410 and the supporting block 420 of the vehicle lifting device 400, and when the vehicle lifting device 400 is used for lifting the vehicle 1, the elastic member 430 can absorb the impact of the supporting block 420 on the vehicle 1, so that the supporting block 420 is more compliant when contacting with the vehicle 1, and the user experience in the vehicle 1 is improved.

In addition, due to the elastic member 430, when the mobile power conversion device is pushed against the battery in the vehicle 1 to complete the disassembly and the assembly of the battery, the mobile power conversion device can be prevented from instantaneously pushing up the vehicle 1 while pushing up the battery. The elastic piece 430 is matched with the mobile power conversion device to jack the battery and lift the vehicle 1, and the elastic piece 430 is synchronously relaxed and rebounded, so that the supporting block 420 is fully attached to the vehicle 1 to move so as to support the vehicle 1 and bear a part of the weight load of the vehicle, thereby reducing the influence of the mobile power conversion device on the vehicle when the battery is replaced, and further improving the experience of users in the vehicle 1.

Alternatively, in an embodiment of the present application, since the support block 420 contacts and supports the vehicle 1, the wear resistance of the material of the support block 420 may be high to improve the life cycle of the support block 420.

For the lifting arm 410, it needs to have a greater hardness and a greater compression resistance. If the lifting arm 410 contacts the vehicle 1, wear may be caused to the vehicle 1, so that the lifting arm 410 does not contact the vehicle 1 when the vehicle lifting device 300 lifts the vehicle 1, and the hardness of the supporting block 420 for contacting and supporting the vehicle 1 may be smaller than that of the Yu Ju lifting arm 410, so as to reduce the influence of the supporting block 420 on the vehicle 1. Further, the hardness of the support block 420 may be smaller than that of the vehicle contact member in the vehicle 1 that is in contact with the support block 420, thereby reducing the influence of abrasion or the like of the support block 420 on the vehicle contact member.

By way of example, the material of the support block 420 includes, but is not limited to, a resin material. In addition, the material of the lifting arm 410 includes, but is not limited to, a steel material. The material of the vehicle contacts in the vehicle that contact the support blocks 420 includes, but is not limited to, sheet metal material.

In some embodiments, the elastic member 430 may be disposed on a surface of the lifting arm 410 to connect the support block 420 and the lifting arm 410.

In other embodiments, in order to save space occupied by the elastic member 430 and ensure reliability of the elastic member 430 without being disturbed by the outside, the lifting arm 410 is provided with a groove 411, and at least a portion of the elastic member 430 is disposed in the groove 411.

Fig. 5 shows a schematic perspective cross-sectional view of a vehicle lifting device 400 according to an embodiment of the application. The schematic perspective cross-sectional view may be a schematic cross-sectional view taken along the direction A-A' in fig. 4.

It should be noted that, fig. 5 only schematically illustrates a partial area of the lifting arm 410 where the supporting block 420 is located, and the lifting arm 410 is not limited to the schematic structure illustrated in fig. 5. Alternatively, in an embodiment of the present application, the entire structure of the lifting arm 410 may be the same as the lifting arm 410 shown in fig. 4.

As shown in fig. 5, a groove 411 is disposed on a side of the lifting arm 410 facing the supporting block 420, one end of the elastic member 430 may be fixedly disposed on a bottom surface of the groove 411, and the other end of the elastic member 430 is fixedly disposed on the supporting block 420.

As an example, the elastic member 430 shown in fig. 5 is a spring. In some embodiments, the bottom surface of the recess 411 and the support block 420 may be provided with ring-shaped indentations adapted to the springs, and both ends of the springs may be snapped into the indentations such that the springs are fixedly disposed between the lifting arms 410 and the support block 420. Of course, in other embodiments, the springs may be fixedly disposed between the lifting arm 410 and the supporting block 420 by other connection methods, such as glue connection, mechanical fixing connection, etc., which is not limited in this embodiment of the present application.

In addition, in the embodiment shown in fig. 5, the elastic member 430 includes only a single spring, which is correspondingly disposed at the middle of the recess 411 and the supporting block 420, so as to perform a good elastic supporting function. In other examples, the elastic member 430 may further include a plurality of springs, which may be disposed in the grooves 411 and the supporting blocks 420 in a distributed manner, and the number of springs is not particularly limited in the embodiment of the present application.

Alternatively, as shown in fig. 5, when the vehicle lifting device 400 does not act on the vehicle 1, one end of the elastic member 430 connected to the support block 420 may be located outside the recess 411, such that the support block 420 is located outside the recess 411.

When the vehicle lifting device 400 lifts the vehicle 1, the vehicle 1 presses the support block 420 and the elastic member 430, the elastic member 430 compresses, and the support block 420 falls toward the recess 411. If the supporting block 420 falls into the recess 411, the vehicle 1 contacts the lifting arm 410 with a higher hardness, so that the lifting arm 410 wears the vehicle 1. Therefore, when the vehicle lifting device 400 lifts the vehicle 1, the supporting block 420 needs to be restricted outside the recess 411 to prevent the lifting arm 410 from wearing out of the vehicle 1.

To achieve the above object, in some embodiments, the area of the side of the support block 420 facing the lifting arm 410 is larger than the opening area of the recess 411, so that the support block 420 is restricted outside the recess 410.

As an example, the support block 420 may have a regular quadrangular block structure. The recess 411 may also be a regular quadrilateral recess. Fig. 5 shows only half of the structure of the support block 420 and the recess 411. In the embodiment of the present application, the supporting block 420 with a quadrilateral plate structure is disposed right above the quadrilateral groove 411, and the area of the surface of the supporting block 420 facing the lifting arm 410 is larger than the opening area of the groove 411, so that the supporting block 420 is limited outside the groove 410.

In addition to the above-described manner of controlling the shape area of the supporting block 420 and the recess 411 to be limited outside the recess 410, in other embodiments, the rigidity of the elastic member 430 may be designed to be greater than a predetermined threshold value, so that the supporting block 420 is limited outside the recess 411.

In the embodiment of the present application, the rigidity of the elastic member 430 may be designed according to the weight of an actual vehicle, the depth of the groove, and the like. The greater the rigidity of the elastic member 430, the smaller the deformation thereof and, accordingly, the smaller the displacement of the supporting block 420 under the same external force. Accordingly, the supporting block 420 can be controlled to be restricted outside the recess 411 by the elastic member 430 having a large rigidity. In some implementations, to ensure that the elasticity and rigidity of the elastic member 430 meet the requirements, the elastic member 430 may include a plurality of springs having different elastic parameters.

Through the technical solutions of the two embodiments, the supporting block 420 can be limited outside the groove 411 and cannot fall into the groove 411, and the supporting block 420 is always contacted with and supported by the vehicle 1, so as to prevent the vehicle 1 from contacting with the lifting arm 410 with higher hardness, and further prevent the lifting arm 410 from wearing the vehicle 1.

Optionally, in addition to the lifting arm 410, the supporting block 420, and the elastic member 430 described above, the vehicle lifting device 400 may further include: the limiting structure is used for limiting the movement of the supporting block 420 along the first direction z, wherein the first direction z is a vertical direction when the vehicle lifting device 400 lifts the vehicle 1.

Specifically, in the embodiment of the present application, when the vehicle lifting device 400 lifts the vehicle 1, the supporting block 420 is restricted to move along the vertical direction along with the elastic deformation of the elastic member 430 by the limiting structure, but not move along other directions, such as the horizontal direction, so that the vehicle 1 supported by the supporting block 420 can only move along the vertical direction, but not float in the horizontal direction, so that the user in the vehicle 1 only experiences the up-and-down movement of the vehicle 1, but not the left-and-right shake of the vehicle 1, and the user experience is further improved.

Fig. 6 shows another schematic perspective cross-sectional view of a vehicle lifting device 400 provided by an embodiment of the application.

As an example, the limit structure shown in fig. 6 includes: the guide pins 440 extending in the first direction z, correspondingly, the support blocks 420 are provided with guide channels 421 therein, and the guide channels 421 also extend in the first direction z; the first end of the guide pin 440 is fixedly coupled to the lift arm 410, and the second end of the guide pin 440 is restrained within the guide channel 421 when the support block 420 is moved.

By the above-described mutual engagement of the guide pin 440 and the guide channel 421 extending in the z-direction, the movement of the support block 420 can be restricted only in the z-direction, which is the vertical direction when the vehicle lifting device 400 lifts the vehicle 1, and thus the mutual engagement of the guide pin 440 and the guide channel 421 extending in the vertical direction can restrict the movement of the support block 420 only in the vertical direction. In this embodiment, a partial region of the multiplexing support block 420 is used as a guide channel 421 to cooperate with the guide pin 440 to limit the support block 420, so that the limiting effect is good and the excessive space is not occupied, and in addition, the structure is convenient for connection, installation and disassembly and separation between the support block 420 and the guide pin 440.

Optionally, in an embodiment of the present application, the limiting structure may include: one or more guide pins 440 extending in a first direction z. In the case that the limiting structure includes one guide pin 440, the guide pin 440 may be disposed corresponding to the center of the support block 420, i.e., the guide channel 421 engaged with the guide pin 440 is located at the center of the support block 420. Alternatively, in case that the limiting structure includes a plurality of guide pins 440, the plurality of guide pins 440 are distributed corresponding to the supporting block 420, for example, as shown in fig. 6, the plurality of guide pins 440 are distributed corresponding to the center and four corners of the supporting block 420, i.e., the plurality of guide channels 421 engaged with the plurality of guide pins 440 are located at the center and four corners of the supporting block 420, respectively. By arranging a plurality of guide pins 440 and distributing the guide pins corresponding to the supporting blocks 420, the limiting effect of the limiting structure on the supporting blocks 420 can be further ensured.

Of course, the limiting structure may be other types of structures besides the form of the guide pin 440, for example, a retaining wall disposed around the supporting block 420, and the embodiment of the present application does not limit the specific form of the limiting structure, and is intended to limit the movement of the supporting block 420 to the z direction.

Fig. 7 shows a partially enlarged schematic view of the portion B in fig. 6.

As shown in fig. 7, the second end of the guide pin 440 is provided with a first step structure 4401, and the guide passage 421 of the support block 420 is provided with a second step structure 4211 which is engaged with the first step structure 4401, so as to prevent the second end of the guide pin 440440 from being separated from the guide passage 421, thereby improving the reliability of the engagement of the guide pin 440 with the guide passage and the overall reliability of the vehicle lifting device 400.

Specifically, the second end of the guide pin 440 may protrude outward in the horizontal direction to form a protrusion, and a face of the protrusion facing the first end of the guide pin 440 and a side face of the guide pin 440 form a first step structure 4401. Correspondingly, a second step structure 4211 is provided in the guide channel 421 of the support block 420 towards one end of the lifting arm 410. Optionally, the guide channel 421 may include a first channel segment and a second channel segment, where the second channel segment is located on a side of the first channel segment facing the lifting arm 410, and the second channel segment has a smaller diameter than the first channel segment, and a connection between the first channel segment and the second channel segment forms a second step structure 4211.

The above-described manner is merely an exemplary manner for realizing the first step structure 4401 and the second step structure 4211 in the embodiment of the present application, and other manners in the related art may be employed in addition to the above-described manner to form the first step structure 4401 and the second step structure 4211 that are engaged with each other, aiming to be able to restrict the second end of the guide pin 440 to the guide channel 421 of the support block 420.

Of course, in addition to the first step structure 4401 and the second step structure 4211 which are engaged with each other, for example, the guide pin 440 and the guide channel 421 may be provided as a reverse taper or the like engaged with each other, and the second end of the guide pin 440 may be limited to the guide channel 421, which is not particularly limited in the embodiment of the present application.

In other implementations of embodiments of the present application, the first end of the guide pin 440 may be fixedly coupled directly to the lift arm 410.

Referring back to fig. 6, in other implementations of the embodiment of the present application, the vehicle lifting device 400 may further include a fixing plate 450, the first end of the guide pin 440 is fixed to the fixing plate 450, and the fixing plate 450 is fixedly connected to the lifting arm 410, so that the first end of the guide pin 440 is fixedly connected to the lifting arm 410.

By the technical scheme of the embodiment, the first end of the guide pin 440 is fixed to the fixing plate 450, and the guide pin 440 is arranged on the lifting arm 410 by using the fixing plate 450, so that the installation, the disassembly and the maintenance of the guide pin 440 are facilitated.

Alternatively, in an embodiment of the present application, the design of the fixing plate 450 may be adapted to the design of the guide pin 440, and in the case that the limiting structure includes one guide pin 440, the area of the fixing plate 450 may be relatively small. In the case where the limiting structure includes a plurality of guide pins 440, for example, when the plurality of guide pins 440 are distributed corresponding to the center and four corners of the supporting block 420, the area of the fixing plate 450 may be relatively large so that it can fix the first ends of the plurality of distributed guide pins 440 at the same time.

In the embodiment shown in fig. 6, the fixing plate 450 is disposed opposite to the supporting block 420, and a large space is provided between the fixing plate 450 and the supporting block 420. Alternatively, the elastic member 430 may be disposed between the fixing plate 450 and the supporting block 420.

By the technical scheme of the embodiment, the space between the fixing plate 450 and the supporting block 420 can be reused to install the elastic member 430, so that the structural design among the components is more compact, and the space occupied by the components is saved.

Alternatively, in some embodiments, the securing plate 450 may be secured directly to the surface of the lifting arm 410.

Alternatively, in other embodiments, as shown in FIG. 6, a recess 411 may be provided in the lifting arm 410, and a fixing plate 450 may be positioned in the recess 411 to save installation space of the fixing plate 450 on the lifting arm 410.

In this embodiment, the depth of the recess 411 in the first direction z may be greater than the thickness of the fixing plate 450 in the first direction z, so that the fixing plate 450 may be completely accommodated in the recess 411. One end of the elastic member 430 connected to the fixing plate 450 may be located in the recess 411, and the other end of the elastic member 430 connected to the supporting block 420 may be located outside the recess 411.

In order to limit the supporting block 420 to the outside of the groove 411 and prevent the vehicle 1 from contacting the lifting arm 410 with a higher hardness to prevent the lifting arm 410 from wearing the vehicle 1, in the embodiment of the present application, the related design of the groove 411 and the supporting block 420 may be referred to the related description of the embodiment shown in fig. 5, which is not repeated here.

In addition, when the support block 420 lifts the vehicle 1, the support block 420 receives pressure applied by the vehicle 1, so that the second end of the guide pin is not exposed to the support block 420, and damage to the guide pin and damage to the vehicle 1 are prevented. In the first direction z, a distance D between the support block 420 and a first portion of the lifting arm 410 is not greater than a length L of the guide channel 421, wherein the first portion is a peripheral portion of the recess 411 in the lifting arm 410.

As shown in fig. 6, when the support block 420 is used to support the vehicle 1, the vehicle 1 applies pressure to the support block 420, and the support block 420 moves downward, and the maximum displacement distance of the support block 420 due to the restriction of the peripheral portion of the recess 411 is a distance D shown in the figure, that is, a distance between the support block 420 and the peripheral portion of the recess 411 in the lifting arm 410.

In order to prevent the second end of the guide pin from being exposed to the support block 420 during the downward movement of the support block 420, the length L of the guide channel 421 in the support block 420 needs to be greater than the above-mentioned distance D, i.e., the second end of the guide pin is still located in the guide channel 421 when the support block 420 is at the maximum displacement distance.

Fig. 8 shows a schematic perspective cross-sectional view of another vehicle lifting device 400 provided by an embodiment of the application.

As shown in fig. 8, in the embodiment of the present application, the vehicle lifting device 400 further includes: a pressure sensor 460 for detecting a pressure applied to the support block 420 by the vehicle 1.

By the technical scheme of the embodiment of the application, the pressure sensor 460 is arranged in the vehicle lifting device 400, so that the pressure information transmitted by the vehicle 1 to the supporting block 420 can be detected in real time and fed back to a relevant control unit, such as a control unit in a power exchange station, when the load of the supporting block 420 exceeds the designed limit value, the control unit controls the vehicle lifting device 400 to stop lifting the vehicle, and therefore, the vehicle lifting device 400 can be protected from being damaged due to overload.

Alternatively, the pressure sensor 460 in the embodiment of the present application may be disposed at any position capable of receiving the pressure of the vehicle 1, for example, the surface of the support block 420, between the elastic member 430 and the lifting arm 460, and the like, which is not particularly limited in the embodiment of the present application.

As an example, as shown in fig. 8, the pressure sensor 460 is fixed to the lifting arm 410, and the elastic member 430 is disposed between the pressure sensor 460 and the support block 420. In this example, the pressure applied by the vehicle 1 to the support block 420 is transferred to the pressure sensor 460 through the elastic member 430, and the pressure sensor 460 is fixed to the lifting arm 410, and the pressure sensor 460 has high stability while enabling pressure detection.

Optionally, in order to save installation space of the pressure sensor 460 and protect the pressure sensor 460, the pressure detection thereof has higher stability. In the embodiment shown in fig. 8, a recess 411 is provided in the lifting arm 410 and a pressure sensor 460 is located in the recess 400.

Alternatively, the depth of the recess 411 may be equal to or greater than the thickness of the pressure sensor 460 in the first direction z, so that the pressure sensor 460 may be completely accommodated in the recess 411.

Fig. 9 shows a schematic perspective cross-sectional view of another vehicle lifting device 400 provided by an embodiment of the application. Fig. 10 shows a perspective exploded view of the vehicle lifting device 400 of fig. 9.

Alternatively, in the embodiment of the present application, the pressure sensor 460 is fixed to the lifting arm 410, the fixing plate 450 is fixed to the pressure sensor 460, the elastic member 430 may be installed between the fixing plate 450 and the supporting block 420, and the pressure applied to the supporting block 420 by the vehicle 1 is transmitted to the pressure sensor 460 through the elastic member 430 and the fixing plate 450, so that the pressure sensor 460 performs pressure detection.

Alternatively, as shown in fig. 9 and 10, a recess 411 is provided in the lifting arm 410, and the pressure sensor 460 and the fixing plate 450 are both provided in the recess 411 to save installation space of both the pressure sensor 460 and the fixing plate 450.

As an example, as shown in fig. 10, the middle of the pressure sensor 460 has a mounting area through which a mounting member can fix the pressure sensor 460 to the bottom of the recess 411. Of course, the pressure sensor 460 may be fixed to the bottom of the recess 411 by other fixing means in the related art in addition to the mounting means.

In the embodiment shown in fig. 4 to 10 above, the vehicle lifting device 400 is described as including one lifting arm 410 as an example, in which case the one lifting arm 410 may correspond to the middle of the vehicle 1 to lift the vehicle 1.

Alternatively, the vehicle lifting device 400 may include a plurality of lifting arms 410, each lifting arm 410 of the plurality of lifting arms 410 being provided with a pressure sensor 460 operable to detect the pressure applied by the vehicle 1 to the support block 420 on each lifting arm 410.

Therefore, by detecting the pressure of the pressure sensor 460 on each lifting arm 410, it can be determined that the load difference born by the supporting block 420 on each lifting arm 410 is too large before and after lifting the vehicle 1, so as to prevent the vehicle 1 from tilting and turning over, and ensure the safety of the vehicle 1 and the user in the vehicle 1.

Alternatively, the power device may include a transmission mechanism 330 and a motor 340 as shown in fig. 3, and may be other types of power devices in the related art, which are intended to provide power and drive the lifting arm 410 to move, which is not limited in this embodiment of the present application.
