DETAILED DESCRIPTION

[0044] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0045] Figure 1This is a schematic diagram of the structure of a cylindrical battery device provided by an exemplary embodiment of the present application. Figure 1 As shown, the cylindrical battery device 200 provided in the embodiment of the present application includes a shell 210 and a cylindrical battery assembly 100. The cylindrical battery assembly 100 is arranged inside the shell 210, and the shell 210 plays a role in bearing and protecting the cylindrical battery assembly 100.

[0046] Figure 2 The schematic diagram of the structure of the cylindrical battery assembly provided in an exemplary embodiment of the present application. The cylindrical battery assembly 100 may include a cylindrical battery 110 and a mounting carrier 120, the mounting carrier 120 cooperates with the cylindrical battery 110, and the mounting carrier 120 may be used to mount the cylindrical battery 110 and limit the cylindrical battery 110.

[0047] Figure 3 for Figure 2 A magnified schematic diagram of center A. Figure 4 This is a schematic diagram of the structure of a matching assembly provided by an exemplary embodiment of the present application at a first viewing angle. Figure 2 and Figure 3 As shown, a slot 121 is provided on one side of the mounting carrier 120 close to the cylindrical battery 110; Figure 4 As shown, the cylindrical battery assembly 100 may also include a mating assembly 130 and a temperature sensing assembly 140. The mating assembly 130 may include an assembly 131 and an elastomer 132. The assembly 131 is snap-connected to the slot 121. The elastomer 132 is disposed between the assembly 131 and the mounting carrier 120. The temperature sensing assembly 140 is disposed on the side of the assembly 131 facing the cylindrical battery 110.

[0048] In practical applications, after the assembly 131 is engaged with the card slot 121, the elastic body 132 is in a compressed state between the assembly 131 and the mounting carrier 120. The elastic body 132 can abut the assembly 131 with its own restoring force, so that the assembly 131 moves in a direction away from the mounting carrier 120. The temperature sensor assembly 140 and the cylindrical battery 110 are arranged at one end of the assembly 131 away from the mounting carrier 120, so that the temperature sensor assembly 140 can abut against the outer wall of the cylindrical battery 110. In this way, the temperature sensor assembly 140 can be used to directly collect the temperature of the outer wall of the cylindrical battery 110, and the collected temperature can represent the real working temperature of the temperature sensor assembly, eliminating the problem of temperature difference that is easy to occur when collecting the working temperature of the cylindrical battery 110 by indirect collection in the related art, and effectively improving the accuracy of the detected temperature of the cylindrical battery 110. At the same time, through such a design, it can be ensured that the temperature sensor assembly 140 always abuts against the outer wall of the cylindrical battery 110, thereby improving the reliability of temperature collection.

[0049] In one embodiment, the elastic body 132 may include a spring, an elastic rubber strip, etc.

[0050] like Figure 3 As shown, the mounting carrier 120 is provided with a receiving groove 122, and at least part of the matching component 130 and the temperature sensing component 140 are received in the receiving groove 122, and the aforementioned card groove 121 is provided on the peripheral wall of the receiving groove 122. In other words, the thickness space of the mounting carrier 120 can be used to assemble part or all of the matching component 130 and the temperature sensing component 140, thereby reducing the occupation of the matching component 130 and the temperature sensing component 140 inside the cylindrical battery assembly 100, and improving the space utilization rate between the cylindrical battery 110 and the mounting carrier 120. The receiving groove 122 is recessed toward the inner side of the mounting carrier 120, that is, toward the cylindrical battery 110, and the receiving groove 122 is provided with an opening on the top wall of the mounting carrier 120, so as to facilitate the matching component 130 to be installed into the receiving groove 122 from the opening, and facilitate installation and disassembly and maintenance. After the cylindrical battery 110 is fixed to the mounting carrier 120 , the matching component 130 and the temperature sensor component 140 can also be freely assembled.

[0051] like Figure 4 As shown, the assembly 131 may include a latch 1311, which is elastically latched with the slot 121. In this way, before assembly, the latch 1311 can be pressed first to cause it to elastically deform, and then a part of the latch 1311 can be latched into the slot 121, and the latch 1311 is elastically reset. In this way, a more stable latching structure can be formed between the latch 1311 and the slot 121, preventing the latch 1311 from easily detaching from the slot 121.

[0052] In one embodiment, a barb portion may be provided on the fastener 1311. After the fastener 1311 is engaged with the slot 121, the barb portion may restrict the fastener 1311 from being separated from the slot 121. Figure 3 and Figure 4 As shown, the card slot 121 can be a through hole that passes through the side wall of the mounting carrier 120. The latch 1311 passes through the card slot 121 from the inner side of the mounting carrier 120 and abuts against the outer side of the mounting carrier 120 through the barb portion, thereby increasing the card contact area and improving the card reliability. Figure 5 The exploded schematic diagram of the buckle and the matching block provided by an exemplary embodiment of the present application. Figure 4 and Figure 5As shown, the assembly 131 may further include a matching block 1312, and the matching block 1312 may include a first side 13121 and a second side 13122 that are arranged opposite to each other, the first side 13121 is detachably connected to the fastener 1311, and the second side 13122 is detachably connected to the temperature sensing assembly 140. In this way, by means of the connection function of the assembly 131, the fastener 1311, the assembly 131 and the temperature sensing assembly 140 can be formed into a whole, which is convenient for fastening to the mounting carrier 120; and by means of the detachable structure between the first side 13121 and the fastener 1311 and the detachable structure between the second side 13122 and the temperature sensing assembly 140, it is convenient to replace the fastener 1311 and the temperature sensing assembly 140 later.

[0053] It should be noted that the aforementioned elastomer 132 is arranged between the snap member 1311 and the mounting carrier 120. After the assembly is completed, the elastomer 132 in the compressed state presses the snap member 1311, and then the temperature sensor assembly 140 is pressed to the outer wall of the cylindrical battery 110 through the snap member 1311 and the matching block 1312.

[0054] In one embodiment, the latching member 1311 and the matching block 1312 may also be integrally formed to form a whole, which is helpful to simplify the assembly process and improve assembly efficiency.

[0055] like Figure 5 As shown, the first side 13121 is provided with a first groove 13123, and the side wall of the latch 1311 protrudes close to the first side 13121 to form a first protrusion 13111, and the first protrusion 13111 is snap-fitted with the first slot 121. In this way, on the first hand, under the premise of realizing a detachable connection between the first protrusion 13111 and the first slot 121, the space occupied by the snap-fit ​​structure between the latch 1311 and the assembly 131 can be reduced, thereby improving the space utilization rate; on the second hand, the assembly between the first protrusion 13111 and the first slot 121 is simple, thereby improving the disassembly and assembly efficiency between the first protrusion 13111 and the first slot 121; on the third hand, the first protrusion 13111 is snap-fitted with the first slot 121, thereby limiting the latch 1311 and the assembly 131 in multiple directions, thereby improving the assembly stability between the latch 1311 and the assembly 131.

[0056] like Figure 5 As shown, the side wall of the buckle 1311 away from the first side 13121 is recessed to form a receiving cavity 13113, the receiving cavity 13113 is arranged toward the mounting carrier 120, and the elastic body 132 is received in the receiving cavity 13113. In this way, the space between the mounting carrier 120 and the buckle 1311 can be fully utilized, and the space utilization rate of the free space between the cylindrical battery 110 and the mounting carrier 120 can be effectively improved.

[0057] like Figure 5 As shown, the top wall of the first protrusion 13111 is the first inclined wall 13112, and the bottom wall of the first groove 13123 is the second inclined wall 13124. The first inclined wall 13112 abuts against the second inclined wall 13124, and the first inclined wall 13112 and the second inclined wall 13124 are both inclined relative to the abutting direction of the elastomer 132. In this way, part of the pressing force between the first inclined wall 13112 and the second inclined wall 13124 can act along the abutting direction of the elastomer 132, so that the elastomer 132 can produce a larger deformation, thereby making the temperature sensing component 140 fit more closely to the outer wall of the cylindrical battery 110, which is beneficial to ensure that the temperature sensing component 140 collects the real and effective working temperature of the cylindrical battery 110. At the same time, the inclined design can facilitate the clamping installation and removal of the first protrusion 13111 and the first groove 13123. It can be seen that the depth of the first groove 13123 can be increased from the clamping direction, thereby improving the convenience of installation and removal, while ensuring the clamping reliability. Figure 5 As shown, the clamping direction is vertically downward.

[0058] It should be noted that the abutment direction of the elastic body 132 can be understood as the same direction as the extension direction of the elastic body 132. After the elastic body 132 is compressed, the direction of the restoring force generated by the elastic body 132 is the abutment direction of the elastic body 132. Figure 4 In the shown state, the abutting direction of the elastic body 132 is horizontal.

[0059] In one embodiment, the first inclined wall 13112 and the second inclined wall 13124 are inclined at an angle relative to the abutting direction of the elastic body 132, generally in the range of 0-90°, for example, the inclination angle may be 15°, 30°, 60°, etc. Preferably, in order to increase the pressing force, the first inclined wall 13112 and the second inclined wall 13124 are inclined at an angle greater than or equal to 45° relative to the abutting direction of the elastic body 132.

[0060] In one embodiment, the first inclined wall 13112 and the second inclined wall 13124 are inclined at equal angles relative to the abutment direction of the elastomer 132, so that the first inclined wall 13112 and the second inclined wall 13124 can be tightly abutted, thereby applying greater pressure to the elastomer 132 and increasing the deformation of the elastomer 132.

[0061] like Figure 5 As shown, the first side 13121 is further provided with a guide inclined wall 13128, and the inclination direction of the guide inclined wall 13128 is the same as the inclination direction of the second inclined wall 13124 (the inclination angles may be the same or different). Figure 5Taking the state shown as an example, when the latch 1311 and the matching block 1312 need to be assembled, the latch 1311 can be firstly connected and fixed with the slot 121, and then the guiding inclined wall 13128 of the matching block 1312 can be firstly abutted against the first inclined wall 13112, and then the matching block 1312 can be relatively slid, that is, moved along the locking direction, and the first groove 13123 can slide into the corresponding position of the first protrusion 13111 along the guiding inclined wall 13128. When the first groove 13123 and the first protrusion 13111 are completely corresponding, The two side walls of the first groove 13123 realize the abutment and limitation of the two side walls of the first protrusion 13111, so that the first protrusion 13111 and the first groove 13123 cooperate and limit, so that the first protrusion 13111 can be conveniently engaged with the first groove 13123, and the situation of being stuck or offset during the engagement process can be prevented, and the assembly efficiency between the buckle 1311 and the matching block 1312 can be effectively improved, and the matching block 1312 provided with the temperature sensor assembly 140 can be easily disassembled separately, which is convenient for maintenance and replacement. It should be noted that the second inclined wall 13124 is inclined relative to the abutment direction of the elastic body 132, and is also inclined relative to the engagement direction, and the height of the two side walls of the first groove 13123 along the engagement direction can also be different, and the height of the side wall close to the guiding inclined wall 13128 is greater than the height of the side wall away from the guiding inclined wall 13128, so as to ensure that the first protrusion 13111 is not easy to be separated from the first groove 13123, and the installation reliability is ensured.

[0062] like Figure 4 and Figure 5 As shown, when the first inclined wall 13112 is in contact with the second inclined wall 13124, a reserved gap 1313 exists between the opposite side walls of the first protrusion 13111 and the first groove 13123 along the inclined direction of the first inclined wall 13112 or the second inclined wall 13124. In other words, the opening size of the first groove 13123 is slightly larger than the overall size of the first protrusion 13111, so that the first protrusion 13111 can be easily inserted into or separated from the first groove 13123 during the disassembly process, thereby effectively improving the disassembly efficiency.

[0063] Figure 6 This is a schematic diagram of the structure of a matching component provided by an exemplary embodiment of the present application at a second viewing angle. Figure 5 and Figure 6As shown, a first limiting wall 13125 and a second limiting wall 13126 are convexly arranged on the second side 13122, and a portion of the temperature sensor assembly 140 is clamped between the first limiting wall 13125 and the second limiting wall 13126. It should be understood that the first limiting wall 13125 and the second limiting wall 13126 can limit the temperature sensor assembly 140, prevent the temperature sensor assembly 140 from deviating in different directions, and ensure that the temperature sensor assembly 140 can be stably assembled on the assembly body 131.

[0064] like Figure 6 As shown, the second side 13122 is concavely provided with a second groove 13127, and part of the temperature sensor assembly 140 is covered by the second groove 13127, and at least part of the second groove 13127 corresponds to the pressing area of ​​the elastic body 132 and part of the temperature sensor assembly 140. In this way, the existence of the second groove 13127 can make part of the temperature sensor assembly 140 suspended in the air, so that the pressing effect of the elastic body 132 will not directly press the temperature sensor assembly 140, and play a certain protective role on the temperature sensor assembly 140. In addition, part of the second groove 13127 corresponds to part of the temperature sensor assembly 140, which is also conducive to heat insulation, thereby preventing the temperature outside the mounting carrier 120 from affecting the accuracy of the temperature acquisition of the temperature sensor assembly 140. Although the outer wall of the cylindrical battery 110 is arc-shaped, in order to increase the contact area between the temperature sensor component 140 and the outer wall of the cylindrical battery 110, the elastic body 132 is used to always ensure that the temperature sensor component 140 is in contact with the cylindrical battery 110. As long as the temperature sensor component 140 and the outer wall of the cylindrical battery 110 are in wired contact, the temperature can be collected. Of course, the contact surface between the temperature sensor component 140 and the outer wall of the cylindrical battery 110 can also be set to be flexible to increase the contact area and ensure reliability.

[0065] Figure 7 A schematic structural diagram of a mounting carrier provided for an exemplary embodiment of the present application. Figure 8 for Figure 7 The enlarged schematic diagram of point B is shown in the figure. Figure 7 and Figure 8 As shown, there are multiple cylindrical batteries 110, and multiple cylindrical batteries 110 are arranged in an array inside the mounting carrier 120. The mounting carrier 120 may include a cylindrical battery holder 125, and the cylindrical battery holder 125 is provided with multiple assembly grooves 1251, and the multiple assembly grooves 1251 cooperate with the multiple cylindrical batteries 110 on the periphery of the array, so that the multiple assembly grooves 1251 can limit the multiple cylindrical batteries 110 on the periphery of the array.

[0066] It should be noted that the side wall of the assembly groove 1251 is provided with the aforementioned card groove 121 and the accommodating groove 122, so that the wall thickness space of the assembly groove 1251 can be used to accommodate part of the assembly matching component 130 and the temperature sensor component 140, thereby reducing the space occupied by the matching component 130 and the temperature sensor component 140 inside the installation carrier 120.

[0067] In one embodiment, the aforementioned mating components 130 and temperature sensing components 140 may be clamped in a plurality of assembly grooves 1251 , so that the plurality of temperature sensing components 140 may respectively collect the temperature of a plurality of cylindrical batteries 110 .

[0068] Fig. 9 for Figure 7 The enlarged schematic diagram is shown in Figure C. Figure 7 and Fig. 9 As shown, the mounting carrier 120 may further include a plurality of limit blocks 126, wherein at least three adjacent limit blocks 126 enclose a limit area 1261, and the plurality of cylindrical batteries 110 inside the array cooperate with the plurality of limit areas 1261, so that the plurality of limit blocks 126 corresponding to the limit area 1261 may limit the cylindrical batteries 110 inside the array.

[0069] It should be noted that, for each limiting area 1261, there is at least one limiting block 126 with a limiting boss 1262 protruding along the height direction of the cylindrical battery 110. On the one hand, the limiting boss 1262 can play a more limiting role on the cylindrical battery 110. On the other hand, the limiting boss 1262 can be provided with the aforementioned card slot 121 and the receiving groove 122, and can be used as a mounting carrier 120 for the matching component 130 and the temperature sensor component 140. Optionally, all the limiting blocks 126 can be set as limiting bosses 1262, and some of the limiting bosses 1262 can be provided with card slots 121 and receiving grooves 122 to install the temperature sensor component 140, or all the limiting bosses 1262 can be provided with card slots 121 and receiving grooves 122, and the temperature sensor component 140 can be selectively installed.

[0070] In one embodiment, the number of the limiting blocks 126 enclosing and forming the limiting area 1261 may be three, four, five, etc.

[0071] It should be understood that when the assembly groove 1251 and the limiting boss 1262 are provided at the same time, the temperature sensing component 140 installed in the assembly groove 1251 collects the temperature of the cylindrical batteries 110 outside the array, and the temperature sensing component 140 installed on the limiting boss 1262 collects the temperature of the cylindrical batteries 110 inside the array. In this way, the working temperature of the cylindrical batteries 110 at different positions in the array arrangement can be directly collected, which is conducive to accurately grasping the working temperature of the cylindrical batteries 110 at different positions.

Figures 10 to 12 As shown, the cylindrical battery assembly 100 may further include a clamp 123, which is sleeved on the outside of the cylindrical battery 110, and a portion of the clamp 123 protrudes outward to form a second protrusion 1231. The second protrusion 1231 cooperates with the aforementioned receiving groove 122 (including the receiving groove 122 arranged on the cylindrical battery holder 125 and / or the receiving groove 122 arranged on the limiting boss 1262), and the inner side of the second protrusion 1231 forms a mounting groove 1232, and at least a portion of the assembly 131 and the temperature sensor assembly 140 are accommodated in the mounting groove 1232, and the elastomer 132 is arranged between the surrounding wall of the mounting groove 1232 and the assembly 131.

[0073] It should be noted that the clamp 123 is clamped between the cylindrical battery 110 and the mounting carrier 120 (including the cylindrical battery bracket 125 and / or the limit block 126), which can compensate for the assembly error between the cylindrical battery 110 and the mounting carrier 120, so that a more stable assembly structure can be achieved between the cylindrical battery 110 and the mounting carrier 120, and can prevent the temperature sensor component 140 from separating from the outer wall of the cylindrical battery 110 when the cylindrical battery 110 expands or vibrates, and can ensure that the temperature sensor component 140 is always pressed against the outer wall of the cylindrical battery 110.

[0074] It should be noted that the clamp 123 can effectively reduce the space occupied between the mounting carrier 120 and the cylindrical battery 110 by providing the aforementioned second protrusion 1231 and the mounting groove 1232, thereby improving the space utilization inside the cylindrical battery assembly 100.

[0075] like Fig.11 and Fig.12 As shown, the peripheral wall of the accommodating groove 122 is further provided with a limiting groove 1221, and the side wall of the second protrusion 1231 is provided with a clamping tooth 1233, and the clamping tooth 1233 cooperates with the limiting groove 1221. In this way, the shaking of the clamp 123 relative to the mounting carrier 120 in the clamping direction can be further limited, and the clamp 123 is prevented from being separated from the mounting carrier 120, ensuring that the temperature sensor assembly 140 can be stably pressed against the outer wall of the cylindrical battery 110.

[0076] In one embodiment, there are multiple limiting grooves 1221, and the number of the latch teeth 1233 is the same as the number of the limiting grooves 1221 and corresponds one to one, further improving the assembly stability between the clamp 123 and the mounting carrier 120. The cross section of the latch teeth 1233 can decrease along the clamping direction, so that the latch teeth 1233 can be easily clamped into the limiting grooves 1221 along the clamping direction.
