Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a locking structure and an electrical device. Background Art

[0002] An electrical device is an electrical device that uses electrical energy to perform specific functions. An electrical device includes a battery and a battery compartment for storing the battery.

[0003] In related art, the battery compartment is equipped with a retaining device that secures the battery in place, ensuring continuous contact between the battery and the electrical contacts, thereby ensuring the stability of the battery's power supply. The retaining device secures the battery in the compartment and prevents removal, preventing the device from continuous, long-term use. Utility Model Content

[0004] The present application provides a locking structure and an electrical device, which ensures a reliable connection between the battery and the battery compartment while allowing the battery to be detached from the battery compartment, thereby facilitating battery replacement for operators.

[0005] In a first aspect, the present application provides a locking structure for fixing a battery in a battery compartment. The locking structure may include: a mounting portion, a connecting portion, an operating portion, a locking portion, and a reset portion. The battery compartment includes a first mounting surface and a second mounting surface arranged opposite to each other, and the first mounting surface is used to place the battery. The mounting portion is connected to the second mounting surface. The connecting portion is slidably connected to the mounting portion so that the connecting portion can slide along a first direction. The operating portion is provided on the connecting portion and is used to control the sliding of the connecting portion. The locking portion is provided on the connecting portion and is used to lock with the locking mating portion of the battery. When the connecting portion slides along the first direction, the locking portion slides together with the connecting portion until the locking portion is separated from the locking mating portion. The reset portion is connected to the connecting portion. The reset portion drives the connecting portion back to the initial position and maintains it at the initial position. The initial position is the position of the connecting portion when the locking portion is locked with the locking mating portion.

[0006] According to the first aspect, the locking structure is fixed to the battery compartment through the mounting portion. The connecting portion is slidably connected to the mounting portion so that the connecting portion can slide along the first direction. The locking portion is provided on the connecting portion and is used to lock with the locking mating portion of the battery, thereby fixing the battery in the battery compartment and ensuring the reliability of the connection between the battery and the battery compartment. The operating portion controls the connecting portion to drive the locking portion to slide along the first direction until the locking portion is separated from the locking mating portion, so that the battery can be detached from the battery compartment, thereby facilitating the operator to complete the replacement of the battery. This ensures that the electrical device can be used continuously for a long time. When the unlocking operation is not performed, the reset portion provided at one end of the connecting portion along the first direction causes the locking portion to continue to be locked with the locking mating portion, so that the battery can be stably fixed in the battery compartment without performing the unlocking operation.

[0007] In one possible design, the locking portion is provided with a first fixing surface, and the locking mating portion is provided with a second fixing surface. The first fixing surface abuts the second fixing surface, and the abutting direction between the first fixing surface and the second fixing surface is perpendicular to the first direction.

[0008] Based on the description of the above embodiment, when the locking portion and the locking mating portion are locked, the first fixing surface abuts against the second fixing surface, so that the battery is fixed in the height direction of the battery compartment, thereby enabling the battery to be fixed in the battery compartment.

[0009] In one possible design, in some embodiments, the locking portion is provided with a first sliding surface. The locking mating portion is provided with a second sliding surface. The first sliding surface abuts the second sliding surface, and the first sliding surface slides along the second sliding surface, allowing the battery to be released from the battery compartment along a second direction. The second direction is the height direction of the battery compartment.

[0010] Based on the description of the above embodiment, when the locking portion slides in the first direction, the first fixing surface separates from the second fixing surface, thereby allowing the battery to be removed from the battery compartment. The first sliding surface abuts the second sliding surface, and the first sliding surface slides along the second sliding surface, allowing the battery to be removed from the battery compartment in the second direction, making it easier for the operator to remove the battery from the battery compartment.

[0011] In a possible design, a first included angle exists between the sliding direction of the first sliding surface and the first direction, so that when the locking portion slides along the first direction, the first sliding surface slides along the second sliding surface. The first included angle is less than or equal to 90°.

[0012] Based on the description of the above embodiment, a first angle is formed between the abutment direction of the first sliding surface and the second sliding surface and the first direction, enabling the first sliding surface to slide along the second sliding surface. The first angle is less than or equal to 90°, so that the sliding displacement of the first sliding surface can be partially converted into displacement of the battery in the second direction, thereby allowing the battery to be removed from the battery compartment along the second direction.

[0013] In a possible design, the first angle may be greater than or equal to 20°.

[0014] Based on the description of the above embodiment, the first angle is greater than or equal to 20°, which shortens the displacement of the locking part in the first direction without affecting the convenient replacement of the battery, avoiding waste of installation space in the battery compartment, thereby reducing production costs.

[0015] In one possible design, the reset portion is an elastic structure. One end of the elastic structure is connected to the connecting portion, and the other end of the elastic structure is fixed to the battery compartment. When the connecting portion is in an initial position, the elastic structure is in an initial state. When the connecting portion slides in a first direction, the elastic structure is compressed or stretched.

[0016] Based on the description of the above embodiment, the elastic structure connected between the connecting portion and the battery compartment generates a restoring force due to the sliding of the connecting portion along the first direction, so that the elastic structure drives the connecting portion to return to the initial position.

[0017] In a possible design, the mounting portion is detachably connected to the second mounting surface.

[0018] Based on the description of the above embodiments, the detachable connection allows the operator to quickly install and remove the installation portion, so that the locking structure can be replaced or maintained, reducing the maintenance cost of the electrical device.

[0019] In one possible design, a first mounting hole is provided on the first mounting surface, the first mounting hole being used to connect the interior of the battery compartment with the exterior of the battery compartment. The operating portion is sleeved in the first mounting hole, and the top surface of the operating portion is higher than the first mounting surface.

[0020] Based on the description of the above embodiment, the operating part is mounted in the first mounting hole provided on the first mounting surface, and the top surface of the operating part is higher than the first mounting surface, so that the operating part can be exposed outside the battery compartment, thereby making it convenient for the operator to control the sliding of the connecting part through the operating part.

[0021] In one possible design, the connecting portion is connected to a plurality of locking portions arranged along the first direction. Furthermore, the battery is provided with a plurality of locking mating portions arranged along the first direction. One locking portion corresponds to one locking mating portion.

[0022] Based on the description of the above embodiment, by arranging and connecting multiple locking portions along the first direction on the connecting portion and providing multiple corresponding locking mating portions on the battery, all locking portions and all locking mating portions are locked and mated one by one, thereby achieving a complete definition of the battery's degrees of freedom and ensuring the reliability of the connection between the battery and the battery compartment.

[0023] In a second aspect, the present application provides an electrical device comprising a battery, a battery compartment, and a locking structure as described in any of the above embodiments. The battery is used to provide power to the electrical device. The locking structure is connected to the battery compartment to secure the battery within the compartment.

[0024] The beneficial effects of the electrical device provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0042] The terms "comprises", "comprising" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover but not exclude other contents. The word "a" or "an" does not exclude the presence of a plurality.

[0043] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0045] The directional words appearing in the following description are all directions shown in the drawings and do not limit the specific structure of this application. For example, in the description of this application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting this application.

[0046] In addition, the expressions indicating directions such as the X direction, Y direction, and Z direction used to illustrate the operation and construction of the various components of this embodiment are not absolute but relative, and although these indications are appropriate when the various components are in the positions shown in the figures, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

It can also refer to internal communication between two elements. A signal connection can refer to a signal connection through a circuit or a signal connection through a media medium, such as radio waves. Those skilled in the art will understand the specific meanings of the above terms in this application.

[0050] An electrical device is an electrical device that uses electricity to perform a specific function. Specifically, an electrical device can be a handheld device, tablet, watch, or other smart product.

[0051] The aforementioned electrical device is powered by a battery. Specifically, the electrical device may include a battery compartment having a receiving cavity, wherein the receiving cavity is provided with electrical contacts. The receiving cavity is used to house the battery. The electrical contacts are used to electrically connect the battery to the electrical device, enabling the battery to power the device. The battery compartment is provided with a retaining device, which is used to secure the battery within the compartment, ensuring continuous contact between the battery and the electrical contacts, thereby ensuring the stability of the power provided by the battery.

[0052] In the related art, the battery has a limited energy capacity and the battery in the battery compartment needs to be replaced regularly to ensure that the electrical device can be used for a long time. The limiting device fixes the battery in the battery compartment and cannot be removed, so the electrical device cannot be used continuously for a long time.

[0053] Based on this, the present application provides a locking structure, which can fix the battery in the battery compartment or detach it from the battery compartment by setting a movable locking part, so that the operator can replace the battery regularly to ensure that the electrical device can be used continuously for a long time. Figure 1-8 Provide specific instructions.

[0054] like Figure 1 As shown, the first aspect of the present application provides a locking structure 1 for fixing a battery 3 in a battery compartment 2. The locking structure 1 may include: a mounting portion 11, a connecting portion 12, an operating portion 13, a locking portion 14, and a reset portion 15. The battery compartment 2 includes a first mounting surface 21 and a second mounting surface 22 arranged opposite to each other. The first mounting surface 21 is used to place the battery 3. The mounting portion 11 is connected to the second mounting surface 22. The connecting portion 12 is slidably connected to the mounting portion 11 so that the connecting portion 12 can slide along a first direction X. The operating portion 13 is provided on the connecting portion 12 and is used to control the sliding of the connecting portion 12. The locking portion 14 is provided on the connecting portion 12 and is used to lock with the locking mating portion 31 of the battery 3. When the connecting portion 12 slides along the first direction X, the locking portion 14 slides together with the connecting portion 12 until the locking portion 14 is separated from the locking mating portion 31. The reset portion 15 is connected to the connecting portion 12. The reset portion 15 drives the connecting portion 12 back to the initial position and keeps it at the initial position. The initial position is the position of the connecting portion 12 when the locking portion 14 and the locking matching portion 31 are locked.

[0055] The battery compartment 2 may include a first mounting surface 21 and a second mounting surface 22 disposed opposite each other. The first mounting surface 21 defines a receiving cavity. The receiving cavity is used to accommodate the battery 3, and the second mounting surface 22 is used to mount the aforementioned locking mechanism 1. Specifically, the first mounting surface 21 may include a first stepped surface and a second stepped surface, with a height difference between the second stepped surface and the first stepped surface. This height difference creates a mounting space for the locking mechanism 1 on the second mounting surface 22.

[0056] like Figure 2 and Figure 3 As shown, the mounting portion 11 can be connected to the second mounting surface 22. Specifically, the connection method can be a fixed connection or a detachable connection.

[0057] Further, if Figure 4 As shown, the mounting portion 11 may include a guide surface 111 and a contact surface 112. The contact surface 112 contacts the connecting portion 12, allowing the connecting portion 12 to slide on the contact surface 112. The guide surface 111 blocks the connecting portion 12 in the non-sliding direction, thereby limiting the connecting portion 12 to slide only in a predetermined sliding direction. The predetermined sliding direction is a first direction X.

[0058] like Figure 1 As shown, the connecting portion 12 may be a strip-shaped structure arranged along the first direction X. Specifically, the connecting portion 12 may include a first connecting surface 121 and a second connecting surface 122. The first connecting surface 121 and the second connecting surface 122 are not coplanar. Specifically, the first connecting surface 121 faces the outside of the battery compartment 2, and the second connecting surface 122 is close to the battery 3 and faces the accommodating cavity of the battery compartment 2.

[0059] like Figure 1 and Figure 4 As shown, the operating portion 13 may be a first protruding structure provided on the first connecting surface 121 , and the operator may control the connecting portion 12 to slide through the operating portion 13 .

[0060] like Figure 1 and Figure 4 As shown, the locking portion 14 can be a second protruding structure provided on the second connecting surface 122. A connecting hole is provided on the above-mentioned first mounting surface 21, and the connecting hole is used to connect the mounting space of the locking structure 1 and the above-mentioned accommodating cavity. The locking portion 14 is provided in the above-mentioned connecting hole so that the locking portion 14 can be connected to the battery 3 provided in the accommodating cavity. Among them, a locking matching portion 31 is provided on the side of the battery 3 facing the second mounting hole 212, and the locking matching portion 31 can be matched with the locking portion 14. For example, Figure 1 As shown, the locking fitting portion 31 may be a mounting groove provided on the battery 3 , and the second protruding structure is engaged in the mounting groove so that the locking fitting portion 31 and the locking portion 14 are engaged and locked.

[0061] Furthermore, the locking portion 14 can slide along with the connecting portion 12. When the connecting portion 12 slides in the first direction X, the locking relationship between the locking portion 14 and the locking engagement portion 31 is released, allowing the battery 3 to be removed from the battery compartment 2, thereby facilitating the operator's replacement of the battery 3. For ease of understanding, the action of releasing the locking relationship between the locking portion 14 and the locking engagement portion 31 can be referred to as an unlocking operation.

[0062] The reset portion 15 is connected to the connecting portion 12 so that the reset portion 15 can apply a reset force to the connecting portion 12. This reset force causes the connecting portion 12 to return to its initial position and maintain it there, allowing the locking portion 14 to remain locked with the locking engagement portion 31. This allows the battery 3 to be stably secured in the battery compartment 2 without requiring an unlocking operation. The initial position is the position of the connecting portion 12 when the locking portion 14 is locked with the locking engagement portion 31.

[0063] In summary, the locking structure 1 is fixed to the battery compartment 2 through the mounting portion 11. The connecting portion 12 is slidably connected to the mounting portion 11 so that the connecting portion 12 can slide along the first direction X. The locking portion 14 is provided on the connecting portion 12 and is used to lock with the locking fitting portion 31 of the battery 3, thereby fixing the battery 3 in the battery compartment 2 and ensuring the reliability of the connection between the battery 3 and the battery compartment 2. The operating portion 13 controls the connecting portion 12 to drive the locking portion 14 to slide along the first direction X until the locking portion 14 separates from the locking fitting portion 31, allowing the battery 3 to be detached from the battery compartment 2, thereby facilitating the operator to complete the replacement of the battery 3. This ensures that the electrical device can be used continuously for a long time. When the unlocking operation is not performed, the reset portion 15 provided at one end of the connecting portion 12 along the first direction X keeps the locking portion 14 locked with the locking fitting portion 31, so that the battery 3 can be stably fixed in the battery compartment 2 when the unlocking operation is not performed.

[0064] Figure 5 It is a schematic diagram of the assembly of the locking portion 14 and the locking matching portion 31 in the locked state. Figure 6 for Figure 5 Exploded view of. Combined Figure 5 and Figure 6 It can be seen that in some embodiments, the locking portion 14 is provided with a first fixing surface 141. The locking engagement portion 31 is provided with a second fixing surface 311. The first fixing surface 141 abuts against the second fixing surface 311, and the abutting direction between the first fixing surface 141 and the second fixing surface 311 is perpendicular to the first direction X.

[0065] When the locking portion 14 is locked with the locking engagement portion 31, the first fixing surface 141 can abut against the second fixing surface 311. Specifically, the abutment direction between the first fixing surface 141 and the second fixing surface 311 is perpendicular to the sliding direction, securing the battery 3 in the aforementioned abutment direction. Specifically, the abutment direction can be the height direction of the battery compartment 2, i.e., the second direction Y.

[0066] In summary, when the locking portion 14 is locked with the locking fitting portion 31 , the first fixing surface 141 abuts against the second fixing surface 311 , so that the battery 3 is fixed in the height direction of the battery compartment 2 , thereby enabling the battery 3 to be fixed in the battery compartment 2 .

[0067] Figure 7 FIG1 is a schematic diagram of the assembly of the locking portion 14 and the locking matching portion 31 in the unlocked state. Figure 5 、 Figure 6 and Figure 7 As can be seen, in some embodiments, the locking portion 14 is provided with a first sliding surface 142. The locking engagement portion 31 is provided with a second sliding surface 312. The first sliding surface 142 abuts against the second sliding surface 312, and the first sliding surface 142 slides along the second sliding surface 312, allowing the battery 3 to be removed from the battery compartment 2 along the second direction Y. The second direction Y is the height direction of the battery compartment 2.

[0068] When the locking portion 14 slides along the first direction X, the first fixing surface 141 separates from the second fixing surface 311 , so that the battery 3 loses its position restraint in the second direction Y, thereby allowing the battery 3 to be removed from the battery compartment 2 .

[0069] Further, such as Figure 8 As shown, when the first sliding surface 142 abuts against the second sliding surface 312 and slides along the second sliding surface 312, a component force in the second direction Y is generated. The above-mentioned component force acts on the battery 3, causing the side of the battery 3 close to the locking structure 1 to be lifted along the second direction Y, making it easier for the operator to remove the battery 3 from the battery compartment 2.

[0070] In summary, when the locking portion 14 slides along the first direction X, the first fixing surface 141 separates from the second fixing surface 311, thereby allowing the battery 3 to be removed from the battery compartment 2. The first sliding surface 142 abuts the second sliding surface 312, and the first sliding surface 142 slides along the second sliding surface 312, allowing the battery 3 to escape from the battery compartment 2 along the second direction Y, making it easier for the operator to remove the battery 3 from the battery compartment 2.

[0071] Specifically, in some embodiments, a first included angle exists between the sliding direction of the first sliding surface 142 and the first direction X, so that when the locking portion 14 slides along the first direction X, the first sliding surface 142 slides along the second sliding surface 312. The first included angle is less than or equal to 90°.

[0072] There is a first angle between the contact direction between the first sliding surface 142 and the second sliding surface 312 and the first direction X, so that kinetic energy in the first direction X can be converted into kinetic energy in the sliding direction of the first sliding surface 142 , thereby enabling the first sliding surface 142 to slide along the second sliding surface 312 .

[0073] Furthermore, the first angle is less than or equal to 90°, so that when the first sliding surface 142 slides, it can generate a component force in the second direction Y. Specifically, when the first sliding surface 142 slides, it can generate a component force in the first direction X and a component force in the second direction Y. The component force in the first direction X acts on the locking portion 14, causing the locking portion 14 to displace in the first direction X, and the component force in the second direction Y acts on the battery 3, causing the battery 3 to displace in the second direction Y.

[0074] In summary, a first angle is formed between the contact direction between the first sliding surface 142 and the second sliding surface 312 and the first direction X, allowing the first sliding surface 142 to slide along the second sliding surface 312. The first angle is less than or equal to 90°, so that the sliding displacement of the first sliding surface 142 can be partially converted into displacement of the battery 3 in the second direction Y, thereby allowing the battery 3 to be removed from the battery compartment 2 along the second direction Y.

[0075] Furthermore, in some embodiments, the first angle may be greater than or equal to 20°.

[0076] The displacement of the locking portion 14 in the first direction X is positively correlated with the displacement of the battery 3 in the second direction Y. The degree of this positive correlation depends on the first angle. Specifically, the degree of positive correlation can be understood as the displacement distance in the first direction X when the displacement in the second direction Y remains unchanged. The greater the displacement distance in the first direction X, the greater the degree of positive correlation.

[0077] Furthermore, the smaller the first angle is, the greater the positive correlation is. When the positive correlation is too large, the locking portion 14 needs to move for a long time in the first direction X, resulting in a waste of installation space in the battery compartment 2 .

[0078] Based on this, the first angle is greater than or equal to 20°, so that the displacement of the battery 3 along the second direction Y remains unchanged, while the displacement of the locking portion 14 in the first direction X is shortened, avoiding waste of installation space in the battery compartment 2, thereby reducing production costs.

[0079] In summary, the first angle is greater than or equal to 20°, which shortens the displacement of the locking portion 14 in the first direction X without affecting the convenient replacement of the battery 3, avoiding waste of installation space in the battery compartment 2, thereby reducing production costs.

[0080] Optimally, in combination with the description in the above embodiment, the first angle may be 45°.

[0081] Figure 1 The specific structure of the reset structure is shown in FIG. Figure 1 It can be seen that in some embodiments, the reset portion 15 is an elastic structure. One end of the elastic structure is connected to the connecting portion 12, and the other end of the elastic structure is fixed to the battery compartment 2. When the connecting portion 12 is in the initial position, the elastic structure is in the initial state. When the connecting portion 12 slides along the first direction X, the elastic structure is compressed or stretched.

[0082] When the elastic structure in its initial state is compressed or stretched, elastic potential energy is generated, and the elastic potential energy generates a restoring force, causing the elastic structure to return to its initial state.

[0083] According to the description of the above embodiment, the elastic structure connected between the connecting portion 12 and the battery compartment 2 generates a restoring force due to the sliding of the connecting portion 12 along the first direction X, so that the elastic structure drives the connecting portion 12 to return to the initial position.

[0084] Specifically, the elastic structure may be a spring.

[0085] Furthermore, the connection between the spring and the connecting portion 12 may include but is not limited to the following two methods:

[0086] Connection method 1: A positioning pin 151 is provided on the connection portion 12 , and one end of the spring is sleeved on the positioning pin 151 .

[0087] Connection method 2: An embedding groove is provided on the connecting portion 12, and one end of the spring is clamped in the embedding groove.

[0088] Furthermore, the connection between the locking portion 14 and the locking mating portion 31 is a rigid connection. That is, the locking structure 1 provided in this application secures the battery 3 in the battery compartment 2 through a rigid connection, greatly improving the reliability of the connection between the battery 3 and the battery compartment 2. Considering that a rigid connection may cause wear and tear in the locking structure 1, thereby affecting the reliability of the connection between the battery 3 and the battery compartment 2, this application also makes the following improvements:

[0089] In some embodiments, the mounting portion 11 is detachably connected to the second mounting surface 22 .

[0090] According to the description of the above embodiment, the detachable connection allows the operator to quickly install and remove the installation portion 11, so that the locking structure 1 can be replaced or maintained, reducing the maintenance cost of the electrical device.

[0091] Specifically, the detachable connection may include but is not limited to a threaded connection, a clamp connection, a pin connection, and a snap connection, etc., which is not specifically limited in this application.

[0092] For example, the mounting portion 11 is clamped on the battery compartment 2. Figure 1 As shown, one or more first clamping structures 221 may be provided on the second mounting surface 22, and one or more second clamping structures 113 may be provided on the mounting portion 11. The first clamping structure 221 is adapted to the second clamping structure 113 so that each first clamping structure 221 is clamped in a second clamping structure 113. The first clamping structure 221 may be a clamping slot or a clamping block. When the first clamping structure 221 is a clamping slot, the second clamping structure 113 is a clamping block. When the first clamping structure 221 is a clamping block, the second clamping structure 113 is a clamping slot. For example, four clamping blocks are provided on the second mounting surface 22, and four clamping slots are provided on the mounting portion 11. The four clamping blocks are respectively clamped in the four clamping slots so that the mounting portion 11 is detachably connected to the battery compartment 2, thereby reducing production costs.

[0093] Furthermore, in order to simplify the operation difficulty for the operator, the lock structure 1 provided by the present application is also improved as follows: Figure 1 It can be seen that in some embodiments, the first mounting surface 21 is provided with a first mounting hole 211, which is used to connect the interior of the battery compartment 2 with the exterior of the battery compartment 2. The operating portion 13 is sleeved in the first mounting hole 211, and the top surface of the operating portion 13 is higher than the first mounting surface 21.

[0094] As can be seen from the above description, the first mounting surface 21 may include a first stepped surface and a second stepped surface. The first mounting hole 211 is provided on the first stepped surface, and the accommodating cavity is provided on the second stepped surface. The distance between the first stepped surface and the bottom of the accommodating cavity is greater than the distance between the second stepped surface and the accommodating cavity. The top of the operating portion 13 is higher than the first stepped surface.

[0095] To sum up, the operating part 13 is mounted in the first mounting hole 211 set on the first mounting surface 21, and the top surface of the operating part 13 is higher than the first mounting surface 21, so that the operating part 13 can be exposed outside the battery compartment 2, so that the operator can conveniently control the connection part 12 to slide through the operating part 13.

[0096] In order to further facilitate the operator to operate the operating portion 13, the top surface of the operating portion 13 may be anti-slip treated.

[0097] Specifically, anti-slip treatment can include but is not limited to the following four methods:

[0098] Method 1: A surface texture design is performed on the top surface of the operating portion 13, such as an uneven pattern, to increase friction and improve anti-slip performance.

[0099] Method 2: The operating portion 13 is made of a material having good anti-slip properties, such as a composite material with anti-slip particles.

[0100] Method 3: spraying an anti-slip coating on the top surface of the operating portion 13 .

[0101] Method 4: an anti-slip pad, an anti-slip patch or an anti-slip strip 131 is provided on the top surface of the operating portion 13 .

[0102] For example, Figure 4 As shown, a plurality of anti-slip strips 131 are provided on the top surface of the operating portion 13, so that the top surface of the operating portion 13 has anti-slip properties, further facilitating the operation of the operator.

[0103] Furthermore, the battery 3 may include batteries of different specifications and sizes. When the battery 3 is too long in the first direction X, the battery 3 is fixed in the battery compartment 2 by only one locking structure 1, resulting in an unreliable connection between the battery 3 and the battery compartment 2.

[0104] Based on this, Figure 5 and Figure 7 As shown, the connecting portion 12 is connected to a plurality of locking portions 14 arranged along the first direction X. Furthermore, the battery 3 is provided with a plurality of locking fitting portions 31 arranged along the first direction X. One locking portion 14 corresponds to one locking fitting portion 31 .

[0105] According to the description of the above embodiment, by arranging and connecting multiple locking portions 14 on the connecting portion 12 along the first direction X, and correspondingly providing multiple locking fitting portions 31 on the battery 3, all locking portions 14 and all locking fitting portions 31 are locked and matched one by one, thereby achieving a complete definition of the degrees of freedom of the battery 3 and ensuring the reliability of the connection between the battery 3 and the battery compartment 2.
