Description

Technical Field

[0001] The present specification relates to the technical field of mechanical equipment, and in particular to a fixing device and a battery replacement system. Background Art

[0002] In daily life, electric vehicles usually use battery replacement to extend their battery life. To facilitate battery replacement, the battery can be fixed to the electric vehicle by tightening the bolts and removed by loosening the bolts, so that the battery can be replaced when it is exhausted, extending the use time of the electric vehicle. However, using bolts to fix and remove batteries often leads to low efficiency in battery replacement, and frequent replacement will cause wear of the bolts, such as torque attenuation of the bolts, making it difficult to ensure the fixing effect.

[0003] Therefore, it is necessary to propose a fixing device and a battery replacement system that are convenient for battery replacement. Summary of the invention

[0023] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of this specification. For ordinary technicians in this field, this specification can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0024] It should be understood that the "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 words can achieve the same purpose, the words can be replaced by other expressions.

[0025] As shown in this specification and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "comprise" and "include" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0026] The fixing device of one or more embodiments of this specification can be applied to various scenarios where objects need to be fixed. In some embodiments, the fixing device can be used to fix objects. In some embodiments, the fixing device can be used to fix the device housing. For example, the fixing device can be used to achieve mutual fixation between chassis housings. In some embodiments, the fixing device can also be used to fix electrical appliances, such as televisions, chandeliers, air conditioners, etc. For example, the fixing device can be used to fix a chandelier to a suspended ceiling; for another example, the fixing device can also be used to fix a television to a wall. In some embodiments, the fixing device can be used to fix a battery. For example, the fixing device can be used to fix a battery to an electric vehicle. For another example, the fixing device can also be used to fix a battery to other devices or equipment.

[0027] In some embodiments, multiple fixing devices can also play a positioning role. For example, the fixing device can be used to stabilize the relative position of the battery and the electric vehicle. Furthermore, by setting multiple fixing devices on the edge of the battery, the battery can be relatively fixed to the electric vehicle when the electric vehicle moves. For another example, the fixing device can be used to stabilize the relative position of the lamp and the ceiling. Furthermore, multiple fixing devices can be used to prevent the round chandelier from rotating on the ceiling.

[0028] In some embodiments, the fixing device can realize a detachable fixed connection between objects. In some embodiments, the fixing device can be used to detachably fix the battery on an electric vehicle. In some embodiments, the fixing device can include a locking member and a clamping member, the locking member can be connected to the electric vehicle, and after the locking member is placed in the fixing hole of the object (such as the battery), the clamping member can fix the battery on another object (such as the electric vehicle). In some embodiments, taking the disassembly and assembly of the battery on the electric vehicle as an example, the locking member can be a threaded hole, and the clamping member can be a bolt. Through the cooperation of the bolt and the threaded hole, the fixed connection between the battery and the electric vehicle can be realized, and by separating the clamping member from the locking member, the disassembly of the battery and the electric vehicle can be realized. However, in actual use, the fixing is often required to be finely operated to avoid interference or deformation between the bolt and the threaded hole. This method is not conducive to the rapid replacement of the battery, and will result in too low efficiency in replacing the battery. In addition, frequent disassembly and installation will cause the attenuation of the matching torque between the bolt and the threaded hole, which will make it difficult for the clamping member and the locking member to cooperate, making it difficult for the battery to be stably fixed and connected to the electric vehicle.

[0029] The fixing device provided in some embodiments of the present specification includes a locking member, a clamping member and an operating member, and the operating member can be operated to make the locking member and the clamping member cooperate to lock or separate to unlock. The installation or removal of the clamping member and the locking member can be achieved only by controlling the movement of the operating member, which can save a lot of loading and unloading time, thereby improving the loading and unloading efficiency. In addition, the cooperation between the clamping member and the locking member does not require delicate operation to achieve, and it is not easy to interfere or deform during the loading and unloading process. It is suitable for multiple disassembly and installation, making the object fixed on the fixing device (such as a battery) more stable.

[0030] It should be understood that the application scenarios of the fixing device of this specification are merely some examples or embodiments of this specification. For ordinary technicians in this field, without paying any creative work, this specification can also be applied to other similar scenarios based on these drawings.

[0031] Figure 1 It is a schematic diagram of the structure of the battery and the fixing device shown in some embodiments of this specification. It should be noted that some embodiments of this specification are described by fixing the battery on the electric vehicle as an example, but this is not a limitation on the application scenario of the fixing device. The fixing device can also be used to fix the relative position between other devices, such as the aforementioned fixing device used to stabilize the relative position of the lamp and the ceiling.

[0032] In some embodiments, the fixing device 100 can be used to fix the battery 200 to the chassis of the electric vehicle. Figure 1, the battery 200 may include several mounting holes, and the fixing device 100 may detachably fix the battery 200 on the electric vehicle through the mounting holes. In some embodiments, a battery 200 may be provided with multiple mounting holes, and accordingly, multiple fixing devices 100 may fix the battery 200 through multiple mounting holes. In some embodiments, multiple fixing devices 100 may be respectively arranged on the edges of the battery 200. For example, for a rectangular battery 200, four mounting holes may be arranged on the four vertex edges of the bottom surface of the rectangular battery 200, and four fixing devices 100 may fix the battery 200 on the electric vehicle through the mounting holes of the rectangular battery 200. In some embodiments, multiple (e.g., 3, 4, etc.) mounting holes may also be arranged on both sides of the rectangular battery 200, and each mounting hole is fixed by a fixing device 100. In this way, the use of multiple fixing devices 100 for fixing can improve the stability of the installation of the battery 200 and prevent the battery 200 from falling due to damage to a fixing device 100.

[0033] Figure 2 is a schematic diagram of a fixing device 100 according to some embodiments of the present specification. Figure 2 , the fixing device 100 may include a locking member 110, a clamping member 120 and an operating member 130. In some embodiments, the locking member 110 may pass through the mounting hole of the battery 200, thereby cooperating with the battery 200, and the position of the locking member 110 and the battery 200 is stabilized by the locking member 110. In some embodiments, the operating member 130 is movably connected to the clamping member 120, and the operating member 130 is operable to enable the locking member 110 and the clamping member 120 to cooperate to lock or separate and unlock. In some embodiments, the operating member 130 can be operably moved from position one 160 to position two 170, so that the clamping member 120 moves from the locked position to the unlocked position. In some embodiments, the movable connection may be a connection mode in which two structures can move relative to each other. For example, the movable connection may be a hinge, that is, the operating member 130 and the clamping member 120 are hinged to each other, and the clamping member 120 can rotate relative to the operating member 130. For another example, the movable connection may be a sliding connection, that is, the clamping member 120 can slide relative to the operating member 130. Other movable connection methods may also be used to allow the operating member 130 and the clamping member 120 to move relative to each other but not to separate from each other.

[0034] In some embodiments, the operating member 130 has a plurality of operating positions relative to the locking member 110, and the operating member 130 can move between the plurality of positions relative to the locking member 110. In some embodiments, the plurality of operating positions can include a position 160 and a position 2 170, and the operating member 130 can move between the position 160 and the position 2 170 relative to the locking member 110. In some embodiments, since the operating member 130 and the clamping member 120 are movably connected, when the operating member 130 moves between the position 160 and the position 2 170 relative to the locking member 110, the operating member 130 can drive the clamping member 120 to move between the locking position and the unlocking position. In some embodiments, the position 160 and the position 2 170 can be set according to the specific structures of the operating member 130 and the clamping member 120. In some embodiments, the locking position can be the position where the clamping member 120 cooperates with the locking member 110. In some embodiments, the unlocking position can be the position where the clamping member 120 is separated from the locking member 110.

[0035] In some embodiments of the present specification, by providing a locking member and a snap-in member, the relative position of the battery and the electric vehicle can be easily fixed, and the stabilization effect is good; by providing an operating member, the locking member and the snap-in member can be locked and unlocked in an operable manner, so that the battery can be easily removed for easy battery replacement.

[0036] Figure 3 1 is a schematic diagram of the structure of the locking member 110 according to some embodiments of the present specification. In some embodiments, the locking member 110 may be a component that provides locking support, which may provide support for the clamping member 120 when it cooperates with the clamping member 120 so that the locking member 110 and the clamping member 120 remain relatively locked. In some embodiments, as Figure 3 As shown, the locking member 110 may be provided with a locking portion 112, and the locking portion 112 is located at one end of the axial extension of the locking member 110. In some embodiments, the locking member 110 includes a lock cap 111, and the lock cap 111 is arranged at the other end of the locking member 110. In some embodiments, the lock cap portion 111 of the locking member 110 can be connected to the electric vehicle (such as the chassis). The locking portion 112 of the locking member 110 can cooperate with the clamping member 120. In some embodiments, the cross-section of the locking member 110 can be circular, triangular, quadrilateral, etc. Correspondingly, the locking member 110 can be cylindrical, triangular prism, quadrangular prism, etc. In some embodiments, the locking member 110 can be made of wear-resistant materials, for example, the material of the locking member 110 can include one or more of metal materials (copper, aluminum, chromium, titanium, gold, etc.), metal alloys (copper-aluminum alloy, copper-gold alloy, titanium alloy, aluminum alloy, etc.).

[0037] In some embodiments, the area between the lock cap 111 and the clamping member 120 can be used to place the mounting portion of the battery 200, and the mounting portion is used to mount the battery 200. In some embodiments, the fixing device 100 may further include an elastic gasket 180, which is sleeved on the locking member 120. In some embodiments, when the fixing device 100 fixes the battery 200, the elastic gasket is located between the battery 200 and the lock cap 111, providing buffer protection for the battery 200 and the lock cap 111. In some embodiments, when the locking member 110 is not provided with a lock cap 111, the elastic gasket can be sleeved on the locking member 110, and when the fixing device 100 fixes the battery 200, the elastic gasket is located between the battery 200 and the electric vehicle. In this way, the elastic gasket 180 can alleviate the slight axial movement of the battery 200 during the movement of the electric vehicle, and reduce the friction and collision between the battery 200 and other components.

[0038] In some embodiments, the elastic gasket 180 can be fixedly connected to the lock cap 111 so that the elastic gasket 180 and the locking member 110 are connected as a whole. In some embodiments, when the elastic gasket 180 contacts or connects with the lock cap 111, on the contact surface or the connection surface, the edge of the lock cap 111 is located within the edge of the elastic gasket 180. In some embodiments, the elastic gasket 180 can be in the shape of a circular ring, a rectangular ring, a hexagonal ring, etc. The shape of the elastic gasket 180 can also correspond to the shape of the lock cap 111. If the lock cap 111 is circular, the elastic gasket 180 can be a circular ring. For example, the lock cap 111 can be a circular structure, and the elastic gasket 180 can be a circular structure with a diameter greater than the lock cap 111. In some embodiments, the shape of the elastic gasket 180 may not have a corresponding relationship with the shape of the lock cap 111. For example, the lock cap 111 can be a hexagonal structure, and the elastic gasket 180 can be a circular structure (such as a hexagonal circumscribed circle) that completely covers the lock cap 111. In some embodiments, the elastic gasket 180 may not be fixed to the lock cap 111, but only contact the lock cap 111. By using elastic gaskets of different shapes and structures, different fixing requirements can be met, thereby improving applicability.

[0039] In some embodiments, the elastic gasket 180 can be a gasket made of flexible material, which can buffer the slight axial movement of the battery 200 during the movement of the electric vehicle, thereby reducing the friction and collision between the battery 200 and the lock cap 111, so that the battery 200 is flexibly connected to the vehicle, which can greatly eliminate the manufacturing errors of the vehicle chassis, the manufacturing errors of the fixing device and the operation errors of the electric vehicle.

[0040] In some embodiments, the elastic gasket 180 may be a rubber gasket, a spring gasket, a polyurethane gasket, a sponge gasket, a silicone gasket, etc. The elastic gasket 180 may also be made of other feasible known materials, and the elastic gasket 180 corresponding to appropriate material parameters (such as stiffness and elasticity) may be selected as needed.

[0041] In some embodiments, the stiffness of the elastic gasket 180 may be related to the weight of the device to be fixed (such as battery 200), and the stiffness of the elastic gasket 180 may be negatively correlated with the weight of the battery 200, that is, the heavier the weight, the smaller the stiffness of the elastic gasket 180 is required, thereby achieving a better buffering effect.

[0042] For example, the stiffness of the elastic gasket 180 may be 50-60 degrees of Shore stiffness. For another example, the stiffness of the elastic gasket 180 may be 51-58 degrees of Shore stiffness. For another example, the stiffness of the elastic gasket 180 may be 54-57 degrees of Shore stiffness. For another example, the stiffness of the elastic gasket 180 may be 55-56 degrees of Shore stiffness.

[0043] In some embodiments, the elasticity of the elastic gasket 180 may be related to the weight of the device to be fixed (such as battery 200), and the elasticity of the elastic gasket 180 may be positively correlated with the weight of the battery 200, that is, the heavier the weight, the greater the elasticity of the elastic gasket 180 required, thereby achieving a better buffering effect.

[0044] In this way, the elastic gasket 180 is designed to fit the lock cap 111 and the edge of the elastic gasket 180 is larger than the edge of the lock cap 111, which can avoid contact between the battery 200 and the lock cap 111, further reduce the friction or collision between the battery 200 and structures with higher rigidity such as the electric vehicle or the lock cap 111, and avoid damage to the battery 200.

[0045] Figure 41 is a schematic diagram of the structure of the clamping member 120 shown in some embodiments of the present specification. In some embodiments, the clamping member 120 may be a component that plays a position limiting role after cooperating with the locking member 110. In some embodiments, the clamping member 120 is a component that can switch the locking state and the unlocking state of the fixing device 100, and it can maintain relative locking with the locking member 110 when cooperating with the locking member 110. In some embodiments, when the clamping member 120 moves relative to the locking member 110 in a direction perpendicular to the axis of the locking member 110, the clamping member 120 can be separated from the locking member 110, thereby releasing the clamping member 120 from the locking member 110. In some embodiments, the clamping member 120 may be a structure that can be sleeved or surrounded on the locking member 110. When the locking member 110 cooperates with the clamping member 120, the clamping member 120 can limit the movement of the battery 200 along the axis of one end of the locking portion. In some embodiments, the radius of the lower end (the end close to position one 160) of the clamping member can be greater than the radius of the upper end (the end close to position two 170). In some embodiments, the side of the clip 120 has a smooth transition from top to bottom. In some embodiments, the side of the clip 120 can be a curved surface or a flat surface. In some embodiments, the clip 120 can be in the shape of a hollow cylinder, a hollow prism, or a hollow cone. Figure 4 As shown, the clamping member 120 can be a hollow cone composed of two semi-vertebrae. The shape of the inner side surface of the clamping member 120 can correspond to the shape of the outer side surface of the locking member 110, so that the locking member 110 and the clamping member 120 can fit together when they are matched. For example, if the outer side surface of the locking member 110 is cylindrical, the clamping member 120 can be a hollow shape with a cylindrical inner side surface. In some embodiments, the clamping member 120 can be made of wear-resistant material, for example, the material of the clamping member 120 can include one or more of metal materials (copper, aluminum, chromium, titanium, gold, etc.), metal alloys (copper-aluminum alloy, copper-gold alloy, titanium alloy, aluminum alloy, etc.).

[0046] In some embodiments, the clamping member 120 is provided with a clamping portion 121, which can be arranged on the inner wall of the clamping member 120. The clamping portion 121 can be a component or structure on the clamping member 120 for cooperating with the locking portion 112 to switch between the locked state and the unlocked state. In some embodiments, the clamping portion 121 can bear the load of the battery 200 by cooperating with the locking portion and prevent the battery 200 from moving out of the locking member from the second end, thereby fixing the battery 200. In some embodiments, as Figure 4As shown, the clamping portion 121 can be a groove, a boss or a hole in the clamping member 120 that is perpendicular to the central axis of the clamping member 120. In some embodiments, the shape of the clamping portion 121 can correspond to the shape of the locking portion. For example, if the locking portion 112 is a groove, the shape of the clamping portion 121 can be a boss. When the fixing device 100 is in a locked state, the boss of the clamping portion 121 can be embedded in the groove of the locking portion 112 to achieve locking. When the fixing device 100 is in an unlocked state, the boss of the clamping portion 121 can be withdrawn from the groove of the locking portion 112 to achieve unlocking. For another example, if the locking portion 112 is a boss, the shape of the clamping portion 121 can be a groove, which can achieve locking and unlocking in a similar manner.

[0047] In some embodiments, the locking position and unlocking position of the clamping member 120 are both related to the positions of the locking portion and the clamping member 121. When the clamping member 121 (such as a protrusion) completely enters the locking portion (such as a groove), the clamping member 120 is in the locking position; when the clamping member 121 (such as a protrusion) completely exits the locking portion (such as a groove), the clamping member 120 is in the unlocking position. When the clamping member 120 is in the locking position, the fixing device 100 is in a locked state; when the clamping member 120 is in the unlocking position, the fixing device 100 is in an unlocking state. The locked state may be a state in which the clamping member 120 and the locking member 110 cannot be separated from each other along the axial direction of the locking member 110. The unlocked state may be a state in which the clamping member 120 and the locking member 110 can be separated from each other along the axial direction of the locking member 110. For example, being in a locked state may indicate that the snap-fitting member 120 and the locking member 110 of the fixing device 100 have completed mutual cooperation and can fix the battery 200. Conversely, being in an unlocked state may indicate that the snap-fitting member 120 and the locking member 110 of the fixing device 100 have ceased to cooperate with each other, and the fixing device 100 and the battery can be uninstalled.

[0048] In some embodiments, the clamping member 120 may include at least one locking clip, which can move relative to the operating member 130 along an axis perpendicular to the operating member 130, so that the clamping member 120 moves between the locked position and the unlocked position. The locking clip may be a clip-shaped component arranged along the axial direction of the locking member, and a clamping portion 121 is arranged on the locking clip, which can fit the locking member 110 when the clamping member 120 is in the locked position.

[0049] In some embodiments, the number of locking clips may be two. In some embodiments, the two locking clips are symmetrically distributed relative to the axis of the operating member. In some embodiments, a protrusion (i.e., the clamping portion 121) is provided on the inner side of each locking clip, and correspondingly, two grooves (i.e., the locking portions) symmetrically distributed relative to the axis may be provided on the locking member 110. When the two locking clips are in the locked position, the protrusions on the two locking clips cooperate with the corresponding grooves respectively. In some embodiments, the number of locking clips may be more than two, such as 3, 4, etc. A plurality of locking clips may be distributed around the locking member 110. In some embodiments, the number of locking clips is related to the shape of the locking clip. For example, the locking clip may include two symmetrically arranged hollow semi-cylindrical clips, and the area surrounded by the two clips can be passed through by the locking member 110. For another example, the locking clip may include three tile-shaped clips arranged in three equal parts, and the area surrounded by the three clips can be passed through by the locking member 110.

[0050] In some embodiments, see Figure 1 and Figure 4 , the outer side surface of the locking clip may include a first inclined surface 122, and the end of the first inclined surface 122 close to the first position 160 is inclined in an outward direction relative to the axis of the locking member 110, that is, the end of the first inclined surface 122 close to the first position 160 is away from the axis of the locking member 110, and the end close to the second position 170 is close to the axis of the locking member 110. In some embodiments, the first inclined surface 122 can be the entire outer side surface of the locking clip, or a part of the outer side surface. In some embodiments, during the movement of the operating member between the first position 160 and the second position 170, the first inclined surface 122 can contact the inner side surface of the operating member. Through this contact relationship, the first inclined surface 122 can convert the downward force along the axial direction of the operating member (such as the gravity load applied to the operating member by the battery 200) to the pressure acting on the locking clip perpendicular to the axis inward, and the pressure can make the locking clip have a tendency to move inward perpendicular to the axis, further strengthen the cooperation between the locking clip and the locking member 110, and increase the fixing effect of the fixing device 100.

[0051] Figure 51 is a schematic diagram of the structure of the operating member 130 shown in some embodiments of the present specification. In some embodiments, the operating member 130 can be a component for controlling the switching between the locked state and the unlocked state of the fixing device 100. In some embodiments, the operating member 130 can be operated to make the locking portion 112 and the clamping portion 121 cooperate to lock or separate to unlock. The operating member 130 can drive the clamping member 120 to move by its own movement, thereby changing the relative position of the clamping member 120 and the locking member 110, and realizing the switching between the locked state and the unlocked state of the fixing device 100. For example, the operating member 130 is controlled to move from position 160 to position 2 170 (such as controlling the operating member 130 to move upward), driving the clamping member 120 to move from the locked position to the unlocked position, so that the relative position of the clamping member 120 and the locking member 110 changes from cooperation to separation, and the fixing device 100 switches from the locked state to the unlocked state. The relative position of the clamping member 120 and the locking member 110 can refer to the relevant content of the clamping member 120 and the locking member 110 mentioned above, which will not be repeated here.

[0052] In some embodiments, see Figure 5 , the operating member 130 may be sleeve-shaped. For example, the operating member may be a cylindrical sleeve or a conical sleeve. In some embodiments, the operating member 130 is sleeved on the clamping member 120, and the clamping member 120 may be sleeved on the locking member 110. For example, the locking member 110 may be arranged in the innermost layer, the clamping member 120 may be arranged in the middle layer, and the operating member 130 may be arranged in the outermost layer. In this way, since the operating member 130 is also movably connected with the clamping member 120, the movement of the clamping member 120 in the middle layer is driven by controlling the movement of the operating member 130 in the outermost layer, thereby achieving the fixing and disassembly of the fixing device 100. In some embodiments, the shape of the hollow portion of the operating member 130 may correspond to the shape of the clamping member 120. In some embodiments, the hollow portion of the operating member 130 may provide a movement space for the clamping member 120.

[0053] In some embodiments, the process of installing the battery 200 on the electric vehicle by means of a fixing device and locking the battery 200 is as follows:

[0054] In order to install the battery 200, the lock cap and the buffer gasket of the locking member 110 can be fixed to the electric vehicle first, and then the battery 200 and the clamping unit can be sleeved on the locking member 110 in sequence. In some embodiments, the clamping portion can be pushed upward along the axis of the locking member to the position of the locking portion by external force, and a part of the clamping portion can enter the locking portion in advance. After a part of the clamping portion enters the locking portion, the external force is removed, and the operating member 130 moves downward along the axis of the locking member under the gravity of the battery 200, so that it moves from position 2 170 to position 1 160, and the clamping portion of the clamping member 120 is driven to move toward the inside of the locking portion through the inclined surface of the outer surface of the clamping portion, so that the clamping portion and the locking portion cooperate to achieve the locking of the fixing device 100. In some embodiments, the gravity of the battery 200 can be transmitted to the operating member 130 by the reset member 140, and the operating member 130 is moved downward along the axis of the locking member through the biasing force of the reset member 140 on the operating member 130, so that the clamping member 120 is closed inward, and the clamping part cooperates with the locking part to achieve the locking of the fixing device 100. By using the fixing device of the embodiment of the present specification, the locking of the fixing device 100 can be achieved by only pushing the clamping member upward, and the battery 200 can be fixed to the electric vehicle after locking, thereby improving the installation efficiency of the battery 200.

[0055] In some embodiments, the process of unlocking the fixture 100 and removing the battery 200 is as follows:

[0056] When the fixing device 100 is in a locked state, in order to unlock the fixing device 100, an upward pressure along the axis of the locking member can be applied to the operating member 130, and the pressure can be greater than the gravity of the battery 200 and the fixing device 100, so that the operating member 130 and the guide column 124 provided on the operating member 130 can overcome the biasing force of the reset member 140 and move upward. The guide column 124 is provided in the guide groove 123 provided on the side wall of the clamping member 120, and the clamping part of the clamping member 120 is driven to move outward through the guide groove 123, so that the clamping part is separated from the locking part, and the fixing device 100 is unlocked, so that the above-mentioned clamping whole can be disassembled and separated from the locking member 110. Then, the battery 200 can be disassembled and separated from the locking member 110, so as to realize the disassembly of the fixing device 100.

[0057] By using the fixing device of the embodiment of the present specification, the fixing device can be unlocked by simply pushing the operating member 130 upwards. After unlocking, the battery 200 can be removed from the electric vehicle, thereby improving the battery removal efficiency.

[0058] Figure 6 It is a schematic diagram of the structure of the fixing device shown in other embodiments of this specification.

[0059] In some embodiments, the clamping portion 121 may include a locking piece 125, and the locking portion 112 may include a clamping groove 113, and the locking piece 125 may be operable to extend into or disengage from the clamping groove 113. The clamping groove 113 may be an annular groove shaped and arranged around one end of the locking member 120 extending in the axial direction, and the locking cap 111 is arranged at the other end. In some embodiments, the locking piece 125 is provided with an end matching the clamping groove 113 on one side close to the locking portion 112. For example, when the clamping groove 113 is in a groove shape, the end of the locking piece 125 may be in a convex shape, and the end of the locking piece 125 in a convex shape may extend into the clamping groove 113 in the groove shape, so that the locking piece 125 can limit the movement of the clamping portion 121, thereby achieving a locking effect on the clamping member 120; the end of the locking piece 125 in a convex shape is disengaged from the clamping groove 113 in the groove shape, and the locking piece 125 no longer limits the movement of the clamping portion 121, thereby unlocking the clamping member 120.

[0060] In some embodiments, a first through hole is provided on one side of the locking piece 125 away from the locking portion 112. The first through hole can be used to penetrate an unlocking device that can drive the locking piece 125 to extend into or out of the card slot 113. The unlocking device can be operated to drive the locking piece 125 to move. For more information about the unlocking device, see Figure 7-Figure 8 Related instructions.

[0061] The lock plate cooperates with the card slot in a stable and reliable manner, so that the card connection part and the locking part can be operably locked or unlocked, the locking or unlocking process is smooth, and the operating experience is good.

[0062] In some embodiments, the operating member 130 may further include a limiting block 134, which may be operable to press against or disengage from the locking piece 125 to limit the locking piece 125 in the slot 113, or to allow the locking piece 125 to be moved out of the slot 113. In some embodiments, the outer side of the limiting block 134 may abut against the inner wall of the operating member 130, and the inner side of the limiting block 134 may abut against the locking piece 125, for example Figure 6 The position 161 is shown, so that the limit block 134 presses and limits the locking plate 125, and the locking plate 125 is locked in its position. In some embodiments, the limit block 134 can be operatively moved to not abut against the locking plate 125, for example, from Figure 6 The middle position three 161 moves to the position four 171, thereby releasing the pressing limit on the locking plate 125, and the locking plate 125 can be moved.

[0063] In some embodiments, the limit block 134 has a plurality of operating positions relative to the locking member 110, and the operating member 130 can move between the plurality of positions relative to the locking member 110. In some embodiments, the plurality of operating positions can include a third position 161 and a fourth position 171, and the operating member 130 can move between the third position 161 and the fourth position 171. In some embodiments, when the limit block 134 moves between the third position 161 and the fourth position 171, the locking piece 125 can be operably extended into or out of the card slot 113, thereby achieving locking and unlocking between the locking member 110 and the card connector 120. In some embodiments, the third position 161 and the fourth position 171 can be set according to the specific structures of the operating member 130 and the card connector 120.

[0064] In some embodiments of the present specification, a limit block is provided so that the position of the locking piece can be operably fixed, thereby easily achieving locking and unlocking, with good locking effect and smooth unlocking.

[0065] In some embodiments, the operating member 130 further includes an elastic member 135. In some embodiments, one end (eg Figure 6 The lower end of the locking plate 125 shown in the figure can be connected to the limit block 134. The position of the limit block 134 connected thereto can be changed by compressing the elastic member 135, so as to realize the limit block 134 pressing the locking plate 125 to limit the state (locking state) and the separation state (unlocking state switching). The elastic member 135 can be a spring, a spring, a rubber body, etc. In some embodiments, when the limit block 134 changes from the state of pressing the locking plate 125 to the state of being separated from the locking plate 125, the elastic member 135 is compressed so that the elastic member 135 provides an elastic restoring force when the limit block 134 returns to the state of pressing the locking plate 125.

[0066] The elastic member can enhance the tightness of the limit block against the locking piece and improve the stability of the fixation by providing the elastic member; the elastic member can also automatically restore the state of the limit block, thereby making the operation more convenient.

[0067] In some embodiments, the fixing device 100 may include an upper cover 132 and an end cover 133. The upper cover 132 may be located between the battery 200 and the operating member 130, and the end cover 133 may be used to carry and install the fixing device 100. In some embodiments, the upper cover 132 may be provided with a hole for the clamping member 120 to pass through. In some embodiments, the elastic member 135 may abut against the upper cover 132. The bottom of the upper cover 132 may be grooved, and part of the elastic member 135 may be accommodated in the groove to ensure the stability of the relative position of the elastic member 135 and the upper cover 132.

[0068] In some embodiments, the limit block 134 can be driven by an operable unlocking device. For more information about the unlocking device driving the limit block 134 to move, see Figure 7-Figure 8Related instructions.

[0069] Some embodiments of the present specification can easily lock and unlock the battery by setting a locking plate to cooperate with the card connector and limiting the locking position by a limit block. The structure is simple, the locking effect is good, and the unlocking is not easy to get stuck.

[0072] In some embodiments, Figure 7 and Figure 8 As shown, the battery replacement system further includes an unlocking device, and the unlocking device includes an unlocking claw 360. In some embodiments, the clamping portion 121 includes a locking piece 125, the locking portion includes a slot 113, the locking piece 125 can be operably extended into or out of the slot 113, and the unlocking claw 360 can be operably pulled to extend the locking piece 125 into or out of the slot 113. For more information about the locking piece 125, please refer to Figure 6 Related description.

[0073] In some embodiments, the unlocking jaw 360 may match the first through hole of the locking plate 125 , and the unlocking jaw 360 may be inserted into the first through hole, so that the unlocking jaw 360 can pull the locking plate 125 to move.

[0074] By providing the unlocking clamping claw, the action of the locking piece can be controlled, thereby realizing the locking and unlocking operation of the fixing device, with a simple structure and convenient operation.

[0075] In some embodiments, the clamping member 120 further includes a stopper 134, which can be operated to press or disengage the locking piece 125 to limit the locking piece 125 in the slot 113, or to enable the locking piece 125 to be moved out of the slot 113. For a description of the stopper 134, see Figure 6 Related descriptions. Figure 7 and Figure 8 As shown, the unlocking device further includes an unlocking pressing block 370, and the top of the unlocking pressing block 370 can contact the limit block 134. In some embodiments, an upward force can be applied to the unlocking pressing block 370 so that the unlocking pressing block 370 pushes the limit block 134 upward. When the unlocking pressing block 370 presses the limit block 134, the limit block 134 is separated from the locking piece 125, and the unlocking clamp 360 can operably pull the locking piece 125 out of the slot 113.

[0076] By arranging the unlocking pressing block to press the limiting block, the limiting block can be easily separated from the locking piece, thereby better controlling the locking piece and improving the convenience of unlocking.
