Description

Technical Field

[0001] This application relates to the field of power tool technology, and more specifically, to a mounting bracket and a pouch battery. Background Technology

[0002] As power tools continue to evolve towards lighter and more portable designs, using rechargeable batteries as a power source has become a mainstream design trend. Within the battery pack's internal structure, the main control board (PCB) is used to manage battery charging and discharging, monitor its status, and provide safety protection. The stability and reliability of its installation directly affect the overall battery performance and lifespan.

[0003] In existing technologies, mounting brackets are typically used to position and fix the main control board. Specifically, multiple bolts are used to connect the main control board to the mounting bracket for mechanical fixation. However, this fixing method has several drawbacks: First, the bolted connection structure makes the installation and disassembly of the main control board cumbersome, inefficient, and detrimental to automated production and subsequent maintenance. Second, it is difficult to precisely control the tightening torque during bolt tightening. If the tightening force is too large, the main control board may be subjected to excessive stress in certain areas, leading to cracking of solder joints, damage to components, or deformation of the substrate, thereby affecting circuit function and product reliability. Conversely, insufficient tightening may cause the main control board to loosen, resulting in poor contact or vibration failure. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In existing technologies, the main control board is mechanically fixed by connecting it to the mounting bracket using multiple bolts. However, this fixing method has several drawbacks: First, the bolted connection structure makes the installation and disassembly of the main control board cumbersome, inefficient, and detrimental to automated production and subsequent maintenance. Second, it is difficult to precisely control the tightening torque during bolt tightening. If the tightening force is too large, the main control board may be subjected to excessive stress in certain areas, leading to cracking of solder joints, damage to components, or deformation of the substrate, thereby affecting circuit functionality and product reliability. Conversely, insufficient tightening may cause the main control board to loosen, resulting in poor contact or vibration failure.

[0031] To address the aforementioned technical problems, embodiments of this application provide a mounting bracket and a soft-pack battery.

[0032] Reference Figure 1 , Figure 2As shown in the embodiment of this application, the mounting bracket is configured in a soft-pack battery. The mounting bracket includes a bracket body 100 with a mounting surface 101. A locking structure 102 and a limiting structure 103 are protruding from the mounting surface 101 for mounting the main control board 104 of the soft-pack battery. The locking structure 102 and the limiting structure 103 are respectively located at corresponding ends of the main control board 104. The main control board 104 has a first locking portion 105 and a second locking portion 106 at its two ends. The locking structure 102 abuts against the first locking portion 105 to prevent the main control board 104 from displacing in the direction perpendicular to the mounting surface 101 and in the direction parallel to the mounting surface 101. The limiting structure 103 abuts against the second locking portion 106 to prevent the main control board 104 from displacing in the direction parallel to the mounting surface 101. The first locking portion 105 is an end region of the main control board 104 and includes two right-angled locking angles that can be engaged with the locking structure 102. The second latching part 106 is another end region of the main control board 104. The second latching part 106 includes two limiting angles, which can be latched with the limiting structure 103.

[0033] It should be noted that, in this embodiment of the application, a locking structure 102 and a limiting structure 103 are provided on the bracket body 100 of the mounting bracket. The two structures correspond to the first locking part 105 and the second locking part 106 at both ends of the main control board 104, respectively, so as to realize the rapid positioning and fixing of the main control board 104.

[0034] When the main control board 104 is installed, the first snap-fit ​​part 105 at one end of it is snapped into the snap-fit ​​structure 102 on the bracket body 100. The snap-fit ​​structure 102 not only limits the main control board 104 in the direction parallel to the mounting surface 101, but also provides a blockage in the direction perpendicular to the mounting surface 101 to prevent the main control board 104 from coming off.

[0035] The second latching portion 106 at the other end of the main control board 104 abuts against the limiting structure 103, mainly restricting its movement in the direction parallel to the mounting surface 101. Through the synergistic effect of the latching structure 102 and the limiting structure 103, a stable constraint is formed on the main control board 104 in multiple directions, thereby achieving reliable fixation of the main control board 104 without the need for bolts.

[0036] The technical effects that the embodiments of this application can produce are as follows:

[0037] First, in this embodiment, the main control board 104 achieves rapid installation and disassembly through a snap-fit ​​structure and a limiting structure, significantly improving assembly efficiency and facilitating automated production and subsequent maintenance. Second, this embodiment avoids stress concentration on the main control board caused by improper torque control during bolt tightening, effectively preventing solder joint cracking, component damage, or substrate deformation, thus enhancing the structural integrity and circuit reliability of the main control board 104. Third, the snap-fit ​​structure 102 and the limiting structure 103 are integrated into the bracket body 100, resulting in a compact structure that optimizes the use of internal space in the battery pack. This also enhances the overall structural stability and vibration resistance, thereby improving the overall performance and lifespan of the soft-pack battery.

[0038] Reference Figure 2 , Figure 3 As shown, in one optional implementation, the snap-fit ​​structure 102 includes a first abutting portion 107, a second abutting portion 108, and a third abutting portion 109. The first abutting portion 107 is located on both sides of the main control board 104 along its length, and is used to prevent the main control board 104 from displacing in the first direction X. The second abutting portion 108 is located on the first side of the main control board 104 along its width, and is used to prevent the main control board 104 from displacing in the second direction Y. The third abutting portion 109 is located on the side of the main control board 104 away from the mounting surface 101, and is used to prevent the main control board 104 from displacing in the third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other, and the third direction Z is perpendicular to the mounting surface 101. Specifically, in this embodiment, the first direction is the width direction, the second direction is the length direction, and the third direction is the height direction. It should be noted that the distance from the edge of the first snap-fit ​​portion 105 to the edge of the second snap-fit ​​portion 106 is defined as the length direction of the main control board 104.

[0039] It should be noted that the locking structure 102 in this embodiment of the application provides three mutually cooperating abutment parts—a first abutment part 107, a second abutment part 108, and a third abutment part 109. The abutment surfaces of the three abutment parts and the main control board 104 are perpendicular to each other to form locking angles, thereby achieving omnidirectional positioning of the main control board 104 in three-dimensional space. Among them, the first abutment part 107 is located on both sides of the main control board 104 in the length direction, restricting the movement of the main control board 104 in the first direction X; the second abutment part 108 is located on one side of the main control board 104 in the width direction, restricting its movement in the second direction Y; and the third abutment part 109 is located above the main control board 104, applying constraint to the main control board 104 from the vertical direction to prevent it from detaching from the mounting surface 101 during vibration or impact.

[0040] In this embodiment, the three abutting parts together form a three-dimensional snap-fit ​​structure 102, which engages with the first snap-fit ​​part 105 on the main control board 104. This enables quick insertion and secure positioning, thereby achieving precise positioning and reliable fixation of the main control board 104 without the need for bolts.

[0041] The technical effects that the embodiments of this application can produce are as follows:

[0042] The three-dimensional limiting design significantly improves the stability of the main control board 104 installation, effectively preventing loosening or poor contact caused by external vibration or mechanical impact. At the same time, the three-way contact parts work together to avoid problems such as PCB deformation caused by local stress concentration in traditional bolt fixing, thus improving the structural safety and electrical reliability of the main control board 104. In addition, the clip-on structure 102 facilitates the quick insertion and removal of the main control board 104, greatly improving assembly efficiency and maintenance convenience.

[0043] Reference Figure 3 , Figure 4 as well as Figure 5 As shown, as an optional implementation, the limiting structure 103 includes a first limiting part 110 and a second limiting part 111; the first limiting part 110 is located on both sides of the main control board 104 in the length direction and is used to block the main control board 104 from moving in the first direction X; the second limiting part 111 is located on the second side of the main control board 104 in the width direction and is used to block the main control board 104 from moving in the second direction Y.

[0044] During installation, the first snap-fit ​​portion 105 of the main control board 104 is aligned with the locking structure 102, and the main control board 104 is pushed so that the first snap-fit ​​portion 105 is inserted into the locking structure 102. The third abutment portion 109 clamps the main control board 104 from above, achieving Z-direction (direction perpendicular to the mounting surface 101) limiting. At the same time, the first abutment portion 107 and the second abutment portion 108 form lateral obstructions in the width and length directions, respectively, completing the three-dimensional fixation of this end. Simultaneously, the second snap-fit ​​portion 106 at the other end of the main control board 104 falls into the area of ​​the limiting structure 103, abutting against the first limiting portion 110 (located on both sides in the length direction) and the second limiting portion 111 (located on the second side in the width direction), thereby forming reverse constraints in the X and Y directions to prevent the main control board 104 from retracting or shifting in the length and width directions. The entire process requires no tools; the main control board 104 can be precisely positioned simply by "inserting and pushing," achieving fast and repeatable boltless installation.

[0045] It should be noted that the limiting structure 103 in this application embodiment achieves dual constraint on the second snap-fit ​​portion 106 of the main control board 104 in two orthogonal directions parallel to the mounting surface 101 by setting the first limiting portion 110 and the second limiting portion 111.

[0046] The first limiting part 110 is located on both sides of the main control board 104 in the length direction and is used to limit the movement of the main control board 104 in the first direction X; the second limiting part 111 is located on the second side of the main control board 104 in the width direction, which is the side opposite to the locking structure 102, and is used to limit its displacement in the second direction Y.

[0047] Once the main control board 104 is installed in place, its second latching part 106 cooperates with the limiting structure 103. The first limiting part 110 and the second limiting part 111 together form an enveloping limiting on the main control board 104 from three sides (both sides in the length direction and one side in the width direction). Combined with the blocking of the latching structure 102 on the other side, this effectively prevents the main control board 104 from moving or shifting in the plane parallel to the mounting surface 101, ensuring that it maintains a stable position during the operation of the battery pack.

[0048] The technical effects that the embodiments of this application can produce are as follows:

[0049] By setting a bidirectional limiting part in the limiting structure 103, the positioning accuracy and vibration resistance of the main control board 104 on the bracket body 100 are further enhanced, effectively avoiding problems such as loosening, friction wear or poor electrical contact caused by mechanical vibration or thermal expansion and contraction. At the same time, the limiting structure 103 and the locking structure 102 work together to constrain the main control board 104 in multiple degrees of freedom, significantly improving the reliability and structural stability of the overall installation. In addition, compared with boltless fixing, the limiting structure 103 simplifies the assembly process and improves production efficiency.

[0050] As an optional implementation, the width of the first latching portion 105 matches the spacing between the two first abutting portions 107; and / or, the width of the second latching portion 106 matches the spacing between the two first limiting portions 110.

[0051] It should be noted that, for ease of installation, preferably, the width of the first snap-fit ​​portion 105 can be appropriately smaller than the distance between the two first abutment portions 107, that is, there is a gap between the first snap-fit ​​portion 105 and the first abutment portion 107. Similarly, the width of the second snap-fit ​​portion 106 can be appropriately smaller than the distance between the two first limiting portions 110, that is, there is a gap between the second snap-fit ​​portion 106 and the first limiting portion 110.

[0052] By designing the spacing between the first abutment portions 107 on both sides to be slightly larger than the width of the first latching portion 105, and the spacing between the first limiting portions 110 on both sides to be slightly larger than the width of the second latching portion 106, a suitable assembly gap is formed, thereby providing a certain tolerance space during the installation of the main control board 104. This gap allows the first latching portion 105 to be more easily aligned and slid in when inserted into the latching structure 102, avoiding jamming or difficulty in positioning due to minor dimensional deviations or assembly angle deviations; similarly, the second latching portion 106 can also enter the area of ​​the limiting structure 103 more smoothly and abut against it. This "gap fit" design, combined with a guide structure (such as a chamfer or bevel), gives the main control board 104 a certain degree of fault tolerance during installation, allowing for smooth insertion even with slight assembly deviations.

[0053] In terms of effectiveness, by setting reasonable fitting gaps, the operation difficulty of installing the main control board 104 is significantly reduced, the assembly smoothness and fault tolerance are improved, and it is conducive to achieving tool-free installation with quick, one-handed operation, which greatly improves production efficiency and maintenance convenience.

[0054] Preferably, an elastic covering layer is provided on the first snap-fit ​​portion 105 and the second snap-fit ​​portion 106.

[0055] For example, silicone or rubber is wrapped around the four corners of the main control board 104, and an interference fit is achieved between the elastic covering layer and the locking structure 102 and the limiting structure 103, which effectively improves the stability of the main control board 104.

[0056] When the main control board 104 is installed onto the mounting bracket, these elastic covering layers deform upon contact with the locking structure 102 and the limiting structure 103, thus forming an interference fit. This elastic preload ensures that the main control board 104 is continuously compressed and constrained in the length, width, and vertical directions, effectively filling the tiny gaps between the main control board 104 and the bracket, and enhancing the friction and tightness of the contact surfaces. Through this flexible compression method, the main control board 104 is stably fixed under vibration or impact conditions, preventing it from loosening or shifting.

[0057] The technical effects that the embodiments of this application can produce are as follows:

[0058] This embodiment utilizes flexible elastic materials such as silicone or rubber to achieve an interference fit, which not only significantly improves the stability and vibration resistance of the main control board 104, but also effectively absorbs mechanical shock and thermal stress, reducing stress concentration and PCB damage risks caused by rigid contact. At the same time, the elastic coating layer has good insulation and buffering properties, which can further improve the electrical safety and durability of the main control board 104 under complex working conditions. In addition, this structure still maintains the assembly advantages of boltless and easy insertion, taking into account both high reliability and high efficiency, and is particularly suitable for power tools with high requirements for safety, quietness and long-term stability.

[0059] Reference Figure 3 As shown, as an optional implementation, a support structure 112 is provided on the mounting surface 101. The support structure 112 abuts against the side of the main control board 104 near the mounting surface 101, so that a gap is formed between the main control board 104 and the bracket body.

[0060] The support structure 112 includes at least two protrusions spaced apart on the mounting surface 101.

[0061] It should be noted that a raised support structure 112 is provided on the mounting surface 101 of the mounting bracket. After the main control board 104 is fixed by the snap-fit ​​structure 102 and the limiting structure 103, the side of it closest to the mounting surface 101 abuts against the support structure 112, creating a certain gap between the main control board 104 body and the bracket body. This gap constitutes a heat dissipation space for air circulation, changing the situation of heat accumulation caused by traditional close-fitting installation.

[0062] The heat generated by the main control board 104 during operation can be dissipated to the surrounding air through natural convection and radiation on the PCB surface. At the same time, the gap facilitates the rise of hot air and its replacement by external air, forming a micro-convection heat dissipation channel, thereby effectively improving heat dissipation efficiency and preventing heat from accumulating locally between the main control board 104 and the bracket.

[0063] In terms of effectiveness, the embodiment of this application significantly improves the thermal management performance of the main control board 104 by setting the support structure 112 to form a heat dissipation gap, effectively reduces its operating temperature, prevents component aging, performance degradation or thermal failure caused by excessive temperature rise, and extends the service life of the main control board 104 and the entire battery pack.

[0064] Reference Figure 2 As shown, as an optional implementation, the spacing between the support structure 112 and the third abutment portion 109 in the third direction Z matches the thickness of the main control board 104.

[0065] It should be noted that the distance between the support structure 112 and the third abutment part 109 in the third direction Z perpendicular to the mounting surface 101 is designed to match the thickness of the main control board 104. When the main control board 104 is installed, its bottom contacts the support structure 112 and is lifted upwards, while its top is locked in place by the third abutment part 109 from above. The two form an upper and lower clamping structure for the main control board 104 in the third direction Z. After the main control board 104 is fully assembled, it is in a precise positioning state with minimal gap, no gap, or slight pre-pressure (with a covering layer). This ensures the main control board 104 is firmly fixed in the vertical direction, preventing loosening or jumping, and also achieves effective isolation between the main control board 104 and the mounting surface 101 through the support structure 112, retaining the surrounding air gap as a heat dissipation channel.

[0066] The technical effects that the embodiments of this application can produce are as follows:

[0067] By setting the distance between the support structure 112 and the third abutment part 109 to match the thickness of the main control board 104, the main control board 104 is accurately positioned and reliably clamped in the installation direction, improving the consistency of assembly and structural stability, and effectively preventing poor contact or vibration wear caused by vertical loosening. At the same time, while ensuring mechanical fixation, gaps are still maintained between the main control board 104 and the bracket around its perimeter, which facilitates heat dissipation and balances structural strength and heat dissipation performance. In addition, this design avoids excessive assembly stress and protects the components on the main control board 104 from compression damage.

[0068] Reference Figure 1 , Figure 3 as well as Figure 5 As shown, in one optional embodiment, the second snap-fit ​​part 106 is provided with a connection hole 113, the mounting surface 101 is provided with a connection part 114, and the main control board 104 is provided with a locking member 117 that is locked to the connection part 114 through the connection hole 113.

[0069] It should be noted that in this embodiment, a connecting hole 113 is provided in the second snap-fit ​​portion 106 of the main control board 104, and a connecting portion 114 is provided at a corresponding position on the mounting surface 101 of the mounting bracket. A locking member 117 (such as a screw or rivet) passes through the connecting hole 113 and the connecting portion 114 to achieve localized reinforcement and fixation. Based on the main body's use of a snap-fit ​​structure 102 and a limiting structure 103 for rapid positioning and primary limiting, this structure adds only one locking point at a critical location to further enhance the overall connection rigidity and vibration resistance of the main control board 104.

[0070] The technical effects that the embodiments of this application can produce are as follows:

[0071] This embodiment of the application improves the overall stability and impact and vibration resistance of the main control board 104 by adding a partial locking design to the existing locking and limiting structures without significantly increasing assembly complexity. It is particularly suitable for power tool battery applications under high vibration conditions. At the same time, since the main control board 104 has been precisely positioned by the locking structure 102 and the limiting structure 103, the locking process does not require repeated adjustments, reducing the stress risk caused by bolt tightening. Moreover, the required tightening force is small, avoiding PCB damage caused by excessive tightening.

[0072] In this embodiment, the top surface of the connecting part 114 is flush with the top surface of the support structure 112, and the connecting part 114 can cooperate with the support structure 112 to jointly support the main control board 104.

[0073] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, in one optional implementation, the bracket body 100 is provided with a through hole 115, and the main control board 104 is provided with a temperature detector; the temperature detector passes through the through hole 115 and contacts the cell 116 of the soft-pack battery.

[0074] It should be noted that, in this embodiment, a through hole 115 is provided on the bracket body 100, and a temperature detector (such as a thermistor or temperature sensor) on the main control board 104 is arranged in the corresponding position. This allows the temperature detector to pass through the through hole 115 and directly contact the surface of the cell 116 of the soft-pack battery after the main control board 104 is installed in place. Through this structural design, the through hole 115 serves as a mechanical guide and positioning channel, ensuring that the temperature detector can accurately and stably fit the cell 116 during each assembly, sense its temperature changes in real time, and feed the signal back to the management circuit of the main control board 104, thereby achieving precise monitoring and control of the battery's operating temperature.

[0075] In terms of effectiveness, the embodiments of this application achieve reliable and direct contact between the temperature detector and the battery cell 116 by integrating the through hole 115 structure on the bracket body 100, which significantly improves the response speed and measurement accuracy of temperature acquisition, helps to detect safety hazards such as overheating and abnormal temperature rise in a timely manner, and improves the thermal management capability and safety of the battery system.

[0076] The soft-pack battery provided in this application includes a casing, a main control board 104, a battery cell 116, and the aforementioned mounting bracket; the main control board 104, the mounting bracket, and the battery cell 116 are all disposed inside the casing; the battery cell 116 is located on the side of the mounting bracket away from the main control board 104.

[0077] The soft-pack battery provided in this application embodiment, by integrating the aforementioned mounting bracket, achieves precise positioning and multi-directional limiting of the main control board 104, significantly improving assembly efficiency and structural reliability. Simultaneously, the mounting bracket combines heat dissipation gap design with the guiding positioning function of the temperature detector, effectively improving the heat dissipation performance of the main control board 104 and ensuring reliable contact between the temperature detector and the battery cell 116, thereby enhancing thermal management accuracy and safety. The overall structure is compact, facilitating lightweight and highly integrated battery pack design. While improving the level of production automation, it also enhances the stability and long-term operational reliability of the main control board 104 under complex operating conditions such as vibration and impact.
