[0035] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] As the background section illustrates, in order to save space occupied by the battery and make the internal structure of the terminal device more compact, the battery is usually fixed to the inside of the terminal device's casing by adhesive bonding, forming a strong adhesive layer between the battery and the casing. However, fixing the battery in this way makes it difficult to remove the battery directly when the terminal device is being repaired, and may even damage the casing or the battery, resulting in higher repair costs for the terminal device.

[0037] In view of this, the present invention provides a terminal device, including a device body and a battery. The device body has a battery compartment with a slot inside. The battery includes a shell with a protruding structure. The protruding structure is provided on the battery shell, and the slot is provided in the battery compartment of the device body. The protruding structure slides into the slot, thereby allowing the battery to be quickly installed into or removed from the battery compartment. Compared with the prior art of fixing the battery with adhesive, the battery installation and removal operation of the terminal device of this application is more flexible and convenient. When the terminal device malfunctions and needs repair or battery replacement, it can be quickly replaced, which helps to improve the efficiency of battery installation and removal and reduce the maintenance cost of the terminal device. At the same time, the protruding structure can fix the battery in the slot without the need for an additional adhesive layer on the outer surface of the battery shell, which also helps to save battery installation space and improve the space utilization of the battery compartment.

[0038] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The various embodiments or implementation methods in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to mutually. The embodiments of this application will now be described with reference to the accompanying drawings:

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this application embodiment provides a terminal device 100, including a device body 110 and a battery 120. The device body 110 is provided with a battery compartment 1111, and the battery compartment 1111 has an opening on one side along the thickness direction of the device body 110. The inner wall of the battery compartment 1111 is provided with a slot 1112. The battery 120 includes a shell 121, and the shell 121 is provided with a protruding structure 1211a. The protruding structure 1211a slides with the slot 1112 to allow the battery 120 to enter or exit the battery compartment 1111.

[0040] In this embodiment, the battery 120 can be installed by sliding it into the battery compartment 1111 through the opening of the battery compartment 1111 along the slot 1112. After the protruding structure 1211a is fully slid into the slot 1112, it can also engage with the slot 1112, thereby improving the stability of the battery 120. When the terminal device 100 needs to be repaired, the battery 120 can be removed simply by sliding the protruding structure 1211a along the slot 1112. The operation is simple and convenient, and will not damage the outer shell 121 of the battery 120 or the main body 110 of the device. This helps to improve the efficiency of battery 120 installation and removal and reduce the maintenance cost of the terminal device 100.

[0041] Furthermore, after the battery 120 is installed in the battery compartment 1111, it can be stably fixed in the battery compartment 1111 simply by the cooperation between the protruding structure 1211a and the slot 1112. There is no need to set an additional adhesive layer on the outer surface of the outer shell 121, and the protruding structure 1211a is located in the slot 1112. Therefore, compared with the prior art of fixing the battery 120 by adhesive, the distance between the outer shell 121 of the battery 120 and the inner wall of the battery compartment 1111 is smaller in this embodiment, which is beneficial to improving the space utilization rate in the battery compartment 1111.

[0042] In addition, compared with the prior art where there is an adhesive layer between the battery 120 and the battery compartment 1111, the battery 120 and the battery compartment 1111 are fixed by snap-fit. When the terminal device 100 is subjected to external force impact, the relative displacement of the battery 120 relative to the battery compartment 1111 is smaller, which helps to prevent the battery 120 from being damaged and improves the safety of the battery 120 and the reliability of the terminal device 100.

[0043] In some embodiments, the battery 120 may further include a cell, and the housing 121 defines a cell receiving cavity. The cell is disposed in the cell receiving cavity. When the thickness of the housing 121 and the capacity of the battery compartment 1111 are constant, the distance between the housing 121 and the inner wall of the battery compartment 1111 is reduced, which is beneficial to increase the capacity of the cell receiving cavity, thereby increasing the filling volume of the cell, improving the capacity of the battery 120, and thus enhancing the battery life of the terminal device 100.

[0044] The outer casing 121 can be a metal component, and its wall thickness can be set to a range of 0.02mm-0.2mm. For example, the wall thickness of the outer casing 121 can be 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.15mm, or 0.2mm. The metal material can include titanium alloy, stainless steel, etc. Of course, this embodiment does not limit the material and wall thickness of the outer casing 121; they can be reasonably selected within the above range according to actual needs. By using a thinner metal material, the space occupied by the outer casing 121 can be saved, further increasing the capacity of the battery cell cavity, which is beneficial to further improving the battery life of the terminal device 100.

[0045] Therefore, the terminal device 100 provided in this application embodiment can make the disassembly and assembly of the battery 120 more convenient and faster while ensuring the compactness of the internal structure of the terminal device 100. This is conducive to improving the replacement efficiency of the battery 120, reducing the maintenance cost of the terminal device 100, and also improving the battery life of the terminal device 100.

[0046] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the outer shell 121 of this application embodiment includes: a first middle frame 1211, a first top cover 1212 and a first bottom plate sealing the two ends of the first middle frame 1211. The first middle frame 1211, the first top cover 1212 and the first bottom plate together define the cell receiving cavity. The latching protrusion structure 1211a is formed on the first middle frame 1211.

[0047] In this way, the first middle frame 1211, as the main supporting structure, can provide sufficient strength and stability to ensure that the battery cell is placed safely and stably within the battery cell housing. The first top cover 1212 and the first bottom plate are respectively sealed at both ends of the first middle frame 1211, which can play a role in sealing and protection, preventing the external environment from affecting the battery cell, and also preventing the leakage of electrolyte and other substances inside the battery cell, thereby improving the safety and reliability of the battery 120.

[0048] In addition, the first middle frame 1211, as the main supporting component of the battery 120 casing 121, has high structural strength and can provide stable support for the latching protrusion structure 1211a. Therefore, placing the latching protrusion structure 1211a on the first middle frame 1211 helps to ensure that the latching protrusion structure 1211a will not be deformed or damaged by external force when it is engaged with the latching groove 1112 of the battery compartment 1111.

[0049] In practical implementation, the protruding structure 1211a can be integrally formed with the first middle frame 1211, which helps to improve the accuracy of battery 120 installation, reduce problems caused by assembly errors, simplify the assembly process of the battery 120 casing 121, improve production efficiency, and reduce production costs.

[0050] See also some of the possible implementation methods. Figure 1 , Figure 2 and Figure 4 As shown, the battery cell in this embodiment includes a first tab and a second tab with opposite polarities. For example, the first tab is a positive tab and the second tab is a negative tab; or, the first tab is a negative tab and the second tab is a positive tab. The first tab is electrically connected to the outer casing 121. The outer casing 121 is provided with a terminal post 122, which is electrically connected to the second tab. The terminal post 122 is insulated from the outer casing 121.

[0051] Thus, the outer casing 121 and the terminal post 122 constitute the two electrodes of the battery 120, which simplifies the internal structure of the battery 120, reduces the number of connecting parts, and thus improves the overall stability of the battery 120. At the same time, when the battery 120 is subjected to an external short circuit or other abnormal conditions, the outer casing 121 can quickly disperse the current, reduce the risk of local overheating, and improve the safety of the battery 120.

[0052] See also some of the possible implementation methods. Figures 1 to 5 and Figure 8 As shown, the battery compartment 1111 of this application embodiment includes two sidewalls opposite each other along a first direction. A slot 1112 can be disposed on at least one sidewall of the battery compartment 1111 along the first direction. A protruding structure 1211a is disposed on the sidewall of the outer shell 121 along the first direction opposite to the slot 1112. The slot 1112 includes an inlet end and a stop end. The inlet end is located at the opening. The inlet end and the stop end are offset along the thickness direction of the device body 110 and the second direction, respectively. The protruding structure 1211a is adapted to enter the slot 1112 from the inlet end and slide towards the stop end, so that the battery 120 enters the battery compartment 1111. The first direction, the second direction, and the thickness direction of the device body 110 are perpendicular, and there is an angle between the first direction and the second direction. For example, Figure 1 The X direction is the first direction, the Y direction is the second direction, and the Z direction is the thickness direction of the main body 110 of the equipment.

[0053] In practical implementation, the latching protrusion 1211a of the battery 120 can enter from the inlet end of the latching groove 1112 and slide along the latching groove 1112 to the stop end, thereby ensuring that the battery 120 can be securely installed in the battery compartment 1111. Since the inlet end and the stop end of the latching groove 1112 are offset along the thickness direction and the second direction of the device body 110, respectively, after the latching protrusion 1211a enters the stop end, the stop end can restrict the movement of the battery 120 along the thickness direction of the device body 110, and the latching groove 1112 itself can restrict the movement of the battery 120 along the second direction, thereby improving the stability of the battery 120 installation and enhancing the safety of the battery 120 during use.

[0054] The slot 1112 can be L-shaped, arc-shaped, inclined straight, or other different shapes. This application embodiment does not limit this. As long as the inlet end and the stop end are staggered along the thickness direction and the second direction of the main body 110, the possibility of the card protrusion structure 1211a automatically sliding off along the slot 1112 due to vibration or impact can be reduced, thereby improving the reliability of the terminal device 100.

[0055] See also some of the possible implementation methods. Figures 1 to 5 and Figure 8 As shown, the card slot 1112 in this embodiment of the application includes a first slot segment 1112a and a second slot segment 1112b. The first slot segment 1112a extends along a second direction, and the stop end is located at the end of the first slot segment 1112a away from the second slot segment 1112b. One end of the second slot segment 1112b extends to the opening and forms an inlet end, and the other end of the second slot segment 1112b communicates with the first slot segment 1112a.

[0056] In some embodiments, the first groove segment 1112a provides a stable final position for the latching protrusion structure 1211a of the battery 120, ensuring that the battery 120 can be firmly fixed in the battery compartment 1111 after installation. This helps to limit the movement of the battery 120 along the thickness direction of the device body 110 and prevent the battery 120 from loosening or falling off due to impact or vibration.

[0057] Furthermore, one end of the second groove segment 1112b extends to the opening to form an inlet end, and the other end communicates with the first groove segment 1112a. This allows the latching protrusion structure 1211a of the battery 120 to smoothly enter the latching slot 1112 from the inlet end, slide along the second groove segment 1112b to the first groove segment 1112a, and then slide along the first groove segment 1112a away from the second groove segment 1112b, finally reaching the stop end. The extension direction of the second groove segment 1112b is not limited in this embodiment, as long as it is ensured that the second groove segment 1112b is connected to the first groove segment 1112a and their extension directions are different.

[0058] Furthermore, dividing the card slot 1112 into a first segment 1112a and a second segment 1112b not only reduces the difficulty of installing the battery 120 but also improves the guidance and accuracy of the installation process, allowing users to more easily complete the installation and removal of the battery 120, which is beneficial to improving the maintenance efficiency of the terminal device 100. At the same time, the segmented design also helps to improve the fitting accuracy between the battery 120 and the device body 110, enhancing the overall stability and reliability of the terminal device 100.

[0059] See also some of the possible implementation methods. Figures 1 to 5 and Figure 8 As shown, in this embodiment of the application, the second groove segment 1112b extends along the thickness direction of the device body 110.

[0060] Therefore, when the battery 120 is installed, the cam structure 1211a enters the second groove section 1112b from the inlet end and slides along the thickness direction of the main body 110 to the connection between the first groove section 1112a and the second groove section 1112b, and then slides along the second direction to the stop end. The guidance of the second groove section 1112b is more reasonable and the operation is more convenient, so that users can install or remove the battery 120 more easily.

[0061] See also some of the possible implementation methods. Figures 1 to 5 As shown, in this embodiment of the application, the battery compartment 1111 is provided with multiple slots 1112 on two side walls that are opposite each other along the first direction. The multiple slots 1112 on each side wall are arranged at intervals along the second direction. The outer shell 121 is provided with multiple protruding structures 1211a that correspond one-to-one with the slots 1112.

[0062] In practical implementation, multiple slots 1112 and multiple protrusions 1211a cooperate to form multiple connection points between the battery 120 and the inner wall of the battery compartment 1111, which helps to improve the stability of the connection between the battery 120 and the battery compartment 1111. Simultaneously, the multiple slots 1112 and protrusions 1211a can also disperse various external forces experienced by the battery 120 during use, preventing the battery 120 from becoming loose or damaged due to excessive localized force. Furthermore, they restrict the movement of the battery 120 in different directions, ensuring that the battery 120 is fixed in all directions, which helps to improve the stability and reliability of the battery 120 in the terminal device 100.

[0063] See also some of the possible implementation methods. Figures 1 to 5 and Figure 8As shown, if the height h of the protrusion structure 1211a is too low, it will affect the limiting and guiding function of the protrusion structure 1211a. If the height h of the protrusion structure 1211a is too high, the width h1 of the first groove segment 1112a will be too wide, resulting in an excessively large installation space for the battery 120 and affecting the compactness of the internal structure of the terminal device 100. Therefore, the value range of the height h of the protrusion structure 1211a in this embodiment is: 0.2mm ≤ h ≤ 3.5mm.

[0064] For example, the height h of the protrusion structure 1211a can be 0.2mm, 0.4mm, 0.6mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm or 3.5mm. Of course, the specific value of the height h of the protrusion structure 1211a is not limited in this embodiment of the application, and a reasonable selection can be made within the above range.

[0065] See also some of the possible implementation methods. Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, if the width h1 of the first groove segment 1112a is too narrow, the protruding structure 1211a may not be able to slide smoothly within the first groove segment 1112a, affecting the installation efficiency of the battery 120. If the width h1 of the first groove segment 1112a is too wide, the protruding structure 1211a may have a high degree of freedom along the thickness direction of the device body 110 within the first groove segment 1112a, affecting the stability of the battery 120 within the battery compartment 1111. Therefore, in this embodiment, along the thickness direction of the device body 110, the width h1 of the first groove segment 1112a and the height h of the protruding structure 1211a satisfy: 0≤h1-h≤0.15mm. For example, the difference between the width h1 of the first groove segment 1112a and the height h of the protrusion structure 1211a can be 0, 0.03mm, 0.05mm, 0.1mm, 0.13mm or 0.15mm. Of course, this application embodiment does not limit this, and can reasonably select within the above range according to the actual situation of the battery 120 and the battery compartment 1111.

[0066] Furthermore, along the second direction, if the length L1 of the first groove segment 1112a is too short, it may be difficult to limit the locking structure 1211a in the thickness direction of the equipment body 110. Therefore, the length L1 of the first groove segment 1112a and the length L of the locking structure 1211a satisfy: L1 / L≥2. Along the second direction, if the width L2 of the second groove segment 1112b is too narrow, it will affect the smoothness of the sliding of the locking structure 1211a along the second groove segment 1112b. Therefore, the width L2 of the second groove segment 1112b and the length L of the locking structure 1211a satisfy: L2≥L. For example, the value of L1 / L can be 2, 2.5, 3 or greater, and the value of L2 / L can be 1, 1.5, 2, 2.5, 3, 4 or 5. Of course, the specific values ​​of the length L1 of the first groove segment 1112a, the width L2 of the second groove segment 1112b and the length L of the protrusion structure 1211a are not limited in this application embodiment. They can be reasonably selected according to the specific structure of the battery 120 and the battery compartment 1111.

[0067] See also some of the possible implementation methods. Figure 4 As shown, in this embodiment of the application, the protruding structure 1211a is welded or bonded to the outer shell 121.

[0068] It is understandable that by using welding or bonding, a firm connection can be formed between the protruding structure 1211a and the outer casing 121, thereby ensuring that the protruding structure 1211a will not loosen or fall off due to external forces during the installation and use of the battery 120, which is beneficial to ensuring the stability of the battery 120 in the battery compartment 1111.

[0069] When welding is used to connect the protruding structure 1211a and the outer shell 121, laser welding, resistance welding, and brazing can be selected. Resistance welding involves welding from the contact point between the protruding structure 1211a and the outer shell 121 outwards, which helps avoid the problem of weld penetration in thin parts. When brazing is used, it must be performed before assembling the outer shell 121 to avoid the slow heating and large heat-affected area, which could damage the battery cells inside the cell housing. When adhesive bonding is used to connect the protruding structure 1211a and the outer shell 121, hard adhesive can be used to ensure the connection strength between them. The specific welding or bonding methods are not limited in this embodiment and can be reasonably selected according to the actual assembly needs.

[0070] Alternatively, the protrusion structure 1211a and the outer casing 121 can be integrally formed by stamping. This eliminates the connection gap between the protrusion structure 1211a and the outer casing 121, making the overall structure of the outer casing 121 more complete and robust. Simultaneously, the protrusion structure 1211a and the outer casing 121 exhibit better consistency in material properties and structural strength, enabling them to better withstand various external forces and environmental factors, thereby extending the lifespan of the battery 120. Furthermore, the integral forming process reduces the assembly steps of the battery 120 during production, improving the assembly efficiency of the terminal device 100 and facilitating a more compact battery 120 design, allowing the battery 120 to better fit into the internal space layout of the terminal device 100.

[0071] See also some of the possible implementation methods. Figure 1 and Figure 5 As shown, the main body 110 of the device in this embodiment of the application is further provided with a main component compartment 1113, which is used to house electronic components; the main component compartment 1113 and the battery compartment 1111 are distributed along a second direction, and along the second direction, the stop end is located on the side of the inlet end facing the main component compartment 1113.

[0072] In its implementation, the main body 110 of the device includes a main component compartment 1113 and a battery compartment 1111, allowing the electronic components and the battery 120 to operate independently. This avoids the impact of heat or electromagnetic interference generated by the battery 120 during use on the electronic components, and also facilitates heat dissipation and maintenance of the electronic components. Specifically, the electronic components in the main component compartment 1113 may include circuit boards, memory, cameras, etc. Separating the electronic components and the battery 120 into the main component compartment 1113 and the battery compartment 1111 respectively helps prevent interference between the battery 120 and the electronic components when the terminal device 100 is subjected to external impact, which could lead to safety issues such as battery leakage or short circuits. This improves the safety and reliability of the terminal device 100.

[0073] It should be noted that the main component compartment 1113 is connected to the battery compartment 1111, thereby ensuring that the electronic components in the main component compartment 1113 and the battery 120 in the battery compartment 1111 can form an electrical connection, thus ensuring the performance of the terminal device 100.

[0074] Furthermore, the stop end of the slot 1112 is located on the side facing the main component compartment 1113. After the battery 120 is installed in the battery compartment 1111, the protrusion structure 1211a will be closer to the main component compartment 1113, thereby allowing the connection lines between the battery 120 and the electronic components to be shorter and more compact. This helps to reduce the length of the connection lines and improve the electrical performance and operating efficiency of the terminal device 100. At the same time, it also helps to further enhance the compactness and stability of the internal structure of the terminal device 100.

[0075] See also some of the possible implementation methods. Figures 1 to 5 As shown, the embodiment of this application also includes a positioning component 112. The positioning component 112 is disposed on the main body 110 of the device. When the battery 120 is at the stop end, the positioning component 112 and the battery 120 are limited and cooperated. The positioning component 112 here may be other components such as circuit boards and other electronic components in the main component compartment 1113 and the battery compartment 1111, or it may be a positioning structure set separately for the battery.

[0076] Understandably, the positioning component 112 can limit the position of the battery 120 on the one hand, preventing the battery 120 from sliding further along the first groove segment 1112a, and on the other hand, form a positioning engagement with the battery 120 to ensure that the battery 120 is installed in place and improve the installation accuracy of the battery 120.

[0077] See also some of the possible implementation methods. Figures 1 to 5 As shown, the positioning member 112 has a positioning groove 1121 on one side surface facing the battery compartment 1111, and the outer shell 121 has a positioning protrusion 1211b at one end facing the positioning member 112. The positioning protrusion 1211b is adapted to be embedded in the positioning groove 1121 for positioning and cooperation with the positioning groove 1121.

[0078] In some embodiments, when installing the battery 120, the positioning protrusion 1211b is embedded in the positioning groove 1121 to ensure that the battery 120 is installed in place, which helps to improve the installation accuracy of the battery 120 in the battery compartment 1111. At the same time, the limiting cooperation between the positioning groove 1121 and the positioning protrusion 1211b can also restrict the movement of the battery 120 in both the second direction and the thickness direction of the device body 110, which helps to further improve the stability of the battery 120 in the battery compartment 1111, thereby improving the reliability of the terminal device 100.

[0079] For example, the positioning member 112 can be formed as a positioning platform between the main device compartment 1113 and the battery compartment 1111, or the positioning member 112 can also be formed by other structures inside the battery compartment 1111. This application embodiment does not limit this, as long as it can restrict the movement of the battery 120 along the second direction and the thickness direction of the device 110.

[0080] In practical implementation, if the length of the positioning member 112 along the second direction is too long, it may result in excessive clearance space and waste of space within the terminal device 100. If it is too short, it may result in low structural strength of the positioning member 112, making it difficult to limit the battery 120. Therefore, the length of the positioning member 112 along the second direction can be in the range of 0.5mm-0.9mm. For example, the length of the positioning member 112 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm or 0.9mm. This application embodiment does not limit this, and a reasonable selection can be made within the above range.

[0081] See also some of the possible implementation methods. Figures 1 to 5 As shown, in this embodiment of the application, there are two positioning members 112 that are arranged opposite to each other and spaced apart along the first direction. Each positioning member 112 is provided with a positioning groove 1121 and two positioning protrusions 1211b that are corresponding to the positioning grooves 1121.

[0082] It is understandable that setting two positioning elements 112 simultaneously along the first direction helps to ensure that after the positioning protrusion 1211b and the positioning groove 1121 achieve positioning cooperation, the side of the battery 120 facing the main component compartment 1113 is parallel to the first direction, which helps to further improve the positioning accuracy of the battery 120 and thus improve the reliability of the terminal device 100.

[0083] In addition, the two positioning slots 1121 can also play a certain role in preventing mistakes, making it easier for users to quickly determine the installation direction of the battery 120, which helps to improve the efficiency of battery 120 installation and reduce errors.

[0084] The lengths of the two positioning members 112 along the first direction can be equal or unequal. This application embodiment does not limit this and can make reasonable selections according to the specific shape and structure of the battery compartment 1111. For example, the two positioning members 112 can be set to different lengths so that the lengths of the positioning grooves 1121 on the positioning members 112 along the first direction are different, and the lengths of the corresponding two positioning protrusions 1211b are also different. This can better improve the error-proof effect of the positioning members 112 and quickly determine the installation direction of the battery 120 when installing the battery 120, thereby improving the installation efficiency of the battery 120. Alternatively, the two positioning members 112 can be set to the same length and symmetrically arranged relative to the battery 120 to ensure that the battery 120 is subjected to uniform force and to avoid damage to the battery 120 due to excessive local pressure.

[0085] See also some of the possible implementation methods. Figures 1 to 5As shown, in this embodiment of the application, a clearance space is defined between the two positioning members 112. The clearance space connects the battery compartment 1111 and the main component compartment 1113. A protection plate is provided at one end of the battery 120 facing the main component compartment 1113. The protection plate is located in the clearance space and is used to connect with the electronic components in the main component compartment 1113.

[0086] It should be noted that the clearance space is used to house the battery 120 and electronic components, and provides the necessary space for the connection between the battery 120 and the electronic components in the main component compartment 1113, so that the protection board of the battery 120 can pass through the space smoothly and connect to the electronic components in the main component compartment 1113 without being obstructed.

[0087] Furthermore, the protection board is located within the clearance space. On the one hand, it can protect the end of the battery 120 from external mechanical damage and extend the service life of the battery 120. On the other hand, it ensures that the electrical energy of the battery 120 can be stably and safely transmitted to the electronic components, providing power support for the normal operation of the equipment.

[0088] In addition, the positioning components 112 located on both sides of the protection plate can also protect the protection plate, prevent the protection plate from being subjected to large impacts, and help improve the stability of the connection between the battery 120 and the electronic components.

[0089] The thickness of the protection plate along the thickness direction of the main body 110 can range from 1mm to 4mm. Exemplary protection plate thicknesses can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm. This application embodiment does not impose any limitation on this; any reasonable selection within the above range is acceptable. A detection device can also be installed on the protection plate to monitor the voltage, current, temperature, and other operating conditions of the battery 120, ensuring the safe and stable operation of the battery 120.

[0090] See also some of the possible implementation methods. Figures 1 to 5 As shown, the main body 110 of the device in this embodiment of the application is further provided with a secondary component compartment 1114, which is used to house electronic components; the secondary component compartment 1114 and the battery compartment 1111 are distributed along the second direction and are located on the side of the battery compartment 1111 away from the main component compartment 1113.

[0091] In some embodiments, distributing electronic components in the main component compartment 1113 and the auxiliary component compartment 1114 facilitates better decentralization of functional modules in the terminal device 100, resulting in a clearer and more orderly internal structure. Replacing or repairing electronic components in one of the main component compartment 1113 or the auxiliary component compartment 1114 will not affect the electronic components in the other, further reducing the maintenance cost and improving the maintenance efficiency of the terminal device 100.

[0092] In addition, since the auxiliary component compartment 1114 and the main component compartment 1113 are located on opposite sides of the battery compartment 1111, it helps to avoid electromagnetic interference or heat transfer between the electronic components in the auxiliary component compartment 1114 and the main component compartment 1113. Furthermore, the electronic components in the auxiliary component compartment 1114 and the main component compartment 1113 can dissipate heat independently, which helps to improve heat dissipation efficiency and thus improve the stability and reliability of the terminal device 100.

[0093] Specifically, the electronic components in the auxiliary component compartment 1114 may include speakers, charging interfaces, data interfaces, vibration motors, antennas, SIM card slots, etc.

[0094] See also some of the possible implementation methods. Figures 1 to 5 As shown, the device body 110 of this application embodiment includes: a second middle frame 111, the second middle frame 111 surrounds the battery compartment 1111, and the card slots 1112 are all opened in the second middle frame 111.

[0095] In practical implementation, the second middle frame 111 serves as the main supporting structure in the main body 110 of the device, which can improve the overall structural strength of the main body 110 of the device. The second middle frame 111 encloses the battery compartment 1111, which can protect the battery 120. When the terminal device 100 is subjected to external impact, it reduces the impact force transmitted to the battery 120, thereby preventing the battery 120 from being damaged, which helps to extend the service life of the battery 120 and improve the safety and reliability of the battery 120.

[0096] Furthermore, since the second middle frame 111 has high structural strength, the slot 1112 is opened in the second middle frame 111, which helps to reduce the probability of deformation of the slot 1112, thereby ensuring the accuracy of the fit between the slot 1112 and the protrusion structure 1211a. At the same time, it can also limit the expansion of the battery 120 in the battery compartment 1111, ensuring the stability of the battery 120 installed in the battery compartment 1111.

[0097] The second middle frame 111 can be made of a metal material with high strength and plasticity, such as stainless steel, titanium, aluminum alloy, etc., and this application embodiment does not limit it.

[0098] In some embodiments, see Figure 2 , Figure 5 , Figure 6 and Figure 7The main body 110 may also include a second top cover 113 and a second bottom plate 114. The second top cover 113, the second bottom plate 114 and the second middle frame 111 together form a sub-component compartment 1114. The second middle frame 111 is provided with a mounting groove 1115. The second top cover 113 is provided with a mounting buckle 1131 corresponding to the mounting groove 1115. The second bottom plate 114 is provided with a plurality of limiting posts 1141 extending along the thickness direction of the main body 110. The second top cover 113 is provided with a plurality of first limiting holes 1132 corresponding to the limiting posts 1141.

[0099] A sub-plate 115 is provided between the second top cover 113 and the second bottom plate 114. The sub-plate 115 can be a circuit board, and electronic components are set on the sub-plate 115. At the same time, the sub-plate 115 is provided with a second limiting hole 1151 corresponding to the first limiting hole 1132 and the limiting post 1141. During assembly, the electronic components are first fixed on the sub-plate 115, and then the second limiting hole 1151 is passed through the limiting post 1141 to complete the installation of the sub-plate 115. Finally, the first limiting hole 1132 on the second top cover 113 is aligned with the limiting post 1141 and pressed down to make the mounting buckle 1131 engage with the mounting groove 1115, thereby fixing the second top cover 113 on the second middle frame 111 and completing the closure of the sub-component compartment 1114. The operation is convenient and can be completed without additional installation tools, which helps to improve the assembly efficiency of the terminal equipment 100.

[0100] The second top cover 113 can be made of plastic, which is easy to mass-produce through injection molding, resulting in low production costs. It also possesses high toughness and elasticity, serving as the elastically deformable part in the connection between the mounting clip 1131 and the mounting groove 1115. Furthermore, because the second top cover 113 itself is elastic, it can absorb the impact stress when the terminal device 100 is subjected to external forces, reducing damage to the terminal device 100 and improving its reliability.

[0101] Furthermore, a stop plate 1133 can be provided on the side of the second top cover 113 facing the battery compartment 1111. After the battery 120 is installed, the second top cover 113 is installed. At this time, the stop plate 1133 separates the battery compartment 1111 and the auxiliary component compartment 1114 into two chambers to avoid interference between the battery 120 and the electronic components in the auxiliary component compartment 1114. At the same time, it can limit the movement of the battery 120 along the second direction and ensure the stability of the battery 120 in the battery compartment 1111.

[0102] In summary, the terminal device 100 provided in this application embodiment includes a device body 110 and a battery 120. The device body 110 contains a main component compartment 1113, a battery compartment 1111, and a secondary component compartment 1114 arranged sequentially along a second direction. The battery compartment 1111 is used to install the battery 120, while the main component compartment 1113 and the secondary component compartment 1114 are used to install electronic components. The inner wall of the battery compartment 1111 is provided with a slot 1112, and the inner wall of the battery compartment 1111 near the main component compartment 1113 is provided with a positioning member 112, which has a positioning groove 1121. The battery 120 has a housing 121, on which a protrusion is provided. The structure 1211a and the positioning protrusion 1211b are used to align the protruding structure 1211a with the slot 1112 and slide it from the inlet end of the slot 1112 to the stop end. The positioning protrusion 1211b enters the positioning groove 1121 for a limiting fit, thereby completing the installation of the battery 120. In this way, when the terminal device 100 needs to remove the battery 120 for maintenance, it is only necessary to remove the protruding structure 1211a of the battery 120 along the slot 1112. The operation is simple and convenient, without the need for professional installation tools, and will not damage the battery 120 or the main body of the device 110. This helps to improve the maintenance efficiency of the terminal device 100 and reduce maintenance costs. Meanwhile, the engagement of the cam structure 1211a and the stop end restricts the movement of the battery 120 in the thickness direction of the main body 110, the engagement of the positioning groove 1121 and the positioning protrusion 1211b restricts the movement of the battery 120 in the first direction, and the stop plate 1133 and the positioning member 112 restrict the movement of the battery 120 in the second direction. This achieves the restriction of the degree of freedom of the battery 120 in each direction, which helps to ensure the stability of the battery 120 in the battery compartment 1111 and improve the reliability of the terminal device 100.
