Description

Technical Field

[0001] This application relates to the field of battery compartments, and more particularly to a battery compartment fixing device. Background Technology

[0002] Currently, common battery compartment fixing methods include the following: One method uses a simple snap-fit ​​structure. This involves using interlocking snaps between the battery compartment and the mounting position, utilizing the snaps' elastic deformation to secure the battery compartment. While this method is relatively simple to operate, the snaps have limited elasticity. After significant external impact or prolonged use, the snaps are prone to deformation or wear, leading to a loose battery compartment and wobbling. Another method uses bolts. Multiple bolt holes are provided on the battery compartment and mounting plate, and bolts are used to fasten the battery compartment to the mounting plate. However, this method requires pre-machining precise bolt holes in both the battery compartment and the mounting plate, resulting in higher processing costs. Furthermore, tools are needed during installation and disassembly, making the operation more cumbersome. Additionally, the bolts may loosen over time, causing the battery compartment to wobble.

[0003] Therefore, there is a need for a battery compartment fixing device that can prevent the battery compartment from shaking after it is fixed in place. Utility Model Content

[0004] In view of this, it is necessary to provide a battery compartment fixing device that can prevent the battery compartment from shaking after it is fixed in place, so as to solve the above problems.

[0040] Embodiments of this application provide a battery compartment fixing device, comprising:

[0041] Mounting box;

[0042] A locking cover is disposed on the mounting box along the first direction;

[0043] A fixing compartment is disposed inside the mounting box along the second direction. Both ends of the fixing compartment abut against the inner wall of the mounting box, and the locking cover is disposed opposite to the fixing compartment so that the locking cover extends into the fixing compartment.

[0044] A locking element is located inside the mounting box and extends through the locking cover and the fixing chamber;

[0045] Wherein, the first direction is perpendicular to the second direction.

[0046] The aforementioned battery compartment fixing device, through its design including a mounting box, a locking cover, a fixing compartment, and a locking member, restricts movement in the first direction by embedding the fixing compartment into the mounting box along a second direction, with its two ends abutting against the inner wall of the box. The locking cover is positioned on the mounting box along the first direction and extends into the fixing compartment. The locking member penetrates both the locking cover and the fixing compartment, securing the locking cover and the fixing compartment together to prevent the fixing compartment from moving freely within the mounting box. This multi-layered fixing method works together to ensure the stable fixing of the fixing compartment from the start, preventing any shaking. Furthermore, the installation and disassembly processes are simple and quick, requiring no complex tools, greatly improving work efficiency and reducing labor and time costs.

[0047] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] according to Figures 1-9 This application provides a battery compartment fixing device 100, including: a mounting box 10, a locking cover 20, a fixing compartment 30, and a locking member 40.

[0049] The mounting box 10 is provided with a locking cover 20 along the first direction F1; the mounting box 10 is provided with a fixing chamber 30 along the second direction F2, with both ends of the fixing chamber 30 abutting against the inner wall of the mounting box 10, and the locking cover 20 and the fixing chamber 30 being directly opposite each other so that the locking cover 20 extends into the fixing chamber 30; the locking member 40 is provided in the mounting box 10 and passes through the locking cover 20 and the fixing chamber 30; wherein the first direction F1 and the second direction F2 are perpendicular.

[0050] Specifically, the mounting box 10 is a square structure with four sides enclosed and a hollow center, allowing the fixing chamber 30 to be inserted into the mounting box 10 from both ends. The second direction F2 is the direction of movement of the fixing chamber 30 as it is inserted into the mounting box 10. The first direction F1 is the axial direction of the fixing chamber 30 after it is inserted into the mounting box 10. The fixing chamber 30 is connected and fixed to the mounting box 10 by the locking cover 20.

[0051] Furthermore, the fixing compartment 30 is a cylindrical structure, and the fixing compartment 30 is used to assemble the battery. After the fixing compartment 30 is placed into the mounting box 10, both ends of the fixing compartment 30 abut against the inner wall of the mounting box 10, thereby restricting the movement of the fixing compartment 30 in the first direction F1 within the mounting box 10. The locking cover 20 is a cylindrical structure, and a part of the locking cover 20 can extend into the mounting box 10 and communicate with the fixing compartment 30, while the other part extends out of the mounting box 10 to abut against the mounting box 10. The locking cover 20 can simultaneously restrict the axial and radial movement of the fixing compartment 30, and through the action of the locking member 40, fix the battery compartment in the fixing compartment 30, preventing the fixing compartment 30 from shaking within the mounting box 10.

[0052] Furthermore, the locking element 40 can be any of the following structures: screw, bolt, or pin. After the locking cover 20 extends into the fixing chamber 30 and is aligned with the subsequent locking structure, the fixing chamber 30 and the locking cover 20 are fixed together by the locking element 40, so that the locking cover 20 and the fixing chamber 30 are firmly connected together, making the entire fixing device a stable whole.

[0053] In summary, the fixing chamber 30 is placed into the mounting box 10 along the second direction F2, ensuring that both ends of the fixing chamber 30 are tightly abutted against the inner wall of the mounting box 10, thus completing the initial positioning of the fixing chamber 30. Next, the locking cover 20 is installed on the mounting box 10 along the first direction F1, and its position is adjusted so that it is directly opposite the fixing chamber 30. Then, the locking cover 20 is slowly pushed into the fixing chamber 30. Once the locking cover 20 reaches the appropriate position, the locking member 40 is used to penetrate the locking cover 20 and the fixing chamber 30, securely locking the locking cover 20 and the fixing chamber 30 together.

[0054] In one specific embodiment, the locking cover 20 has a first locking portion 21 and a first guide portion 22. The first locking portion 21 is disposed inside the mounting box 10, and the first guide portion 22 is disposed on the side of the mounting box 10 opposite to the first locking portion 21. The fixing chamber 30 has a second locking portion 31 and a second guide portion 32 extending axially along the second locking portion 31. The first locking portion 21 can extend into the second locking portion 31.

[0055] Specifically, the first locking part 21 cooperates with the second locking part 31 of the fixing compartment 30, and the locking member 40 securely connects the locking cover 20 to the fixing compartment 30, thereby stably fixing the battery compartment within the fixing compartment 30. After the locking cover 20 is installed in place, the first locking part 21 extends into the second locking part 31, forming a mutually restraining structure to prevent relative movement between the locking cover 20 and the fixing compartment 30. The first guide part 22 acts as a guide during the installation of the locking cover 20. When the locking cover 20 is installed onto the mounting box 10, the first guide part 22 guides the locking cover 20 to move in the correct direction, allowing the first locking part 21 to accurately extend into the second locking part 31 of the fixing compartment 30. The first guide part 22 greatly improves the accuracy and efficiency of installation, reducing installation difficulties or insecure fixing caused by positional deviations during the installation process.

[0056] Furthermore, the second guide portion 32 serves to guide the fixing cartridge 30 when it is installed into the mounting box 10. When the fixing cartridge 30 is placed into the mounting box 10, the second guide portion 32 can guide the fixing cartridge 30 to move in the correct direction, so that the fixing cartridge 30 can be accurately aligned with the first locking portion 21 of the locking cover 20 that is subsequently installed.

[0057] In one specific embodiment, the first guide portion 22 has a stop ring 221, which is disposed on the outer peripheral surface of the first locking portion 21; the mounting box 10 has a first mounting opening 11 opened along the first direction F1, the first mounting opening 11 has a stop ring 111 and a protrusion 112, the stop ring 111 and the protrusion 112 are disposed adjacent to each other on the inner peripheral edge of the first mounting opening 11, and the stop ring 111 is disposed on the side of the first mounting opening 11 near the fixing chamber 30; wherein, the stop ring 221 is disposed in the first mounting opening 11 and can abut against the stop ring 111.

[0058] Specifically, the retaining ring 221 serves to position and limit the locking cover 20 during its installation into the mounting box 10. When the locking cover 20 is inserted into the first mounting opening 11 of the mounting box 10 along the first direction F1, the retaining ring 221 gradually moves closer to the first mounting opening 11 as the locking cover 20 moves. When the retaining ring 221 contacts the corresponding structure within the first mounting opening 11, it prevents the locking cover 20 from further penetrating the mounting box 10, thus ensuring that the locking cover 20 is installed in the correct position and preventing over-insertion that could cause interference or damage to other components.

[0059] Furthermore, the first mounting port 11 provides a channel for the locking cover 20 to be installed into the mounting box 10. The first mounting port 11 provides an entrance for the locking cover 20 into the mounting box 10, allowing the locking cover 20 to engage with the fixing compartment 30 to secure the battery compartment. An abutment ring 111 is located on the side of the first mounting port 11 near the fixing compartment 30 and is adjacent to the retaining ring 221. When the locking cover 20 is installed in place, the retaining ring 221 abuts against the abutment ring 111, limiting the insertion depth of the locking cover 20 and positioning it. The abutment ring 111 provides a clear abutment surface for the retaining ring 221, ensuring that the locking cover 20 stops moving after being installed in the correct position. The protrusion 112 provides a positioning point for installing the locking cover 20 and engages with a portion on the locking cover 20, limiting the rotation of the locking cover 20 within the first mounting port 11 to a certain extent.

[0060] In one specific embodiment, the first guide portion 22 further has a positioning groove 222 formed radially inward along the abutment ring 111, and the protrusion 112 can be disposed in the positioning groove 222.

[0061] Specifically, the positioning groove 222 provides a space for the protrusion 112 on the first mounting port 11 of the mounting box 10 to receive and position it. During the installation of the locking cover 20 into the mounting box 10, the protrusion 112 can accurately enter the positioning groove 222, thereby further restricting the movement of the locking cover 20 in the radial and circumferential directions. Thus, after the locking cover 20 is placed on the mounting box 10 along the first direction F1, the locking cover 20 is restricted by the protrusion 112 on the mounting box 10, fixing the locking cover 20 in place and achieving the positioning of the locking cover 20.

[0062] In summary, after placing the fixing chamber 30 into the mounting box 10 along the second direction F2, ensure that both ends of the fixing chamber 30 are tightly abutted against the inner wall of the mounting box 10, and adjust the position of the fixing chamber 30 to ensure that the position of the second locking part 31 of the fixing chamber 30 corresponds to the subsequent installation position of the locking cover 20. Align the positioning groove 222 of the first guide part 22 on the locking cover 20 with the protrusion 112 on the first mounting opening 11 of the mounting box 10. At this time, the positioning groove 222 provides a clear guiding direction for the protrusion 112, and the locking cover 20 is pushed into the first mounting opening 11 along the first direction F1. As the locking cover 20 continues to penetrate deeper into the first mounting opening 11, the abutment ring 221 of the first guide part 22 gradually approaches the abutment ring 111 of the first mounting opening 11. When the abutment ring 221 and the abutment ring 111 abut against each other, and the protrusion 112 is embedded in the positioning groove 222, it indicates that the locking cover 20 has been installed in the correct position, and at this time, stop pushing the locking cover 20.

[0063] In one specific embodiment, the first locking part 21 has a limiting groove 211, which is located at the end of the first locking part 21 away from the first guide part 22; the second locking part 31 has a clamping member 311, which is located on the inner circumferential surface of the fixing chamber 30, and the clamping member 311 can be located in the limiting groove 211.

[0064] Specifically, the main function of the limiting groove 211 is to provide a space for the clamping member 311 of the second locking part 31 to be accommodated and locked. When the locking cover 20 is installed on the fixed chamber 30, the first locking part 21 extends into the second locking part 31, and the clamping member 311 enters the limiting groove 211, thereby restricting the axial and radial movement of the first locking part 21, preventing relative displacement between the locking cover 20 and the fixed chamber 30, and realizing a firm connection between the locking cover 20 and the fixed chamber 30.

[0065] Furthermore, the locking member and the second locking part 31 are integrally connected. The locking member 311 is a protrusion on the inner circumferential surface of the second locking part 31, and the size and shape of the locking member 311 are designed according to the size and shape of the limiting groove 211, so that the locking member 311 can extend into the limiting groove 211. The locking member 311 is a key component for locking the first locking part 21 and the second locking part 31. During the installation of the locking cover 20, the locking member 311 will enter the limiting groove 211 as the first locking part 21 is inserted. Through the mutual cooperation with the limiting groove 211, the first locking part 21 is firmly fixed in the second locking part 31, thereby ensuring a stable connection between the locking cover 20 and the fixing chamber 30.

[0066] In one specific embodiment, the limiting groove 211 includes a guide groove 2111 and a locking groove 2112. The guide groove 2111 extends along the axial direction of the first locking part 21. One end of the locking groove 2112 is connected to the guide groove 2111, and the other end extends along a third direction F3. The clamping member 311 extends into the guide groove 2111 and the locking groove 2112 in sequence. The third direction F3 is along the circumferential direction of the first locking part 21.

[0067] Specifically, the guide groove 2111 extends along the axial direction of the first locking part 21, providing a clear guide path for the clamping member 311 of the second locking part 31 during the installation of the locking cover 20. When the locking cover 20 is installed with the fixing chamber 30, the clamping member 311 first enters the guide groove 2111 and moves along the direction of the guide groove 2111, ensuring that the clamping member 311 smoothly reaches the position of the locking groove 2112. After the clamping member 311 moves along the guide groove 2111 to the position of the locking groove 2112, the fixing chamber 30 is rotated in the third direction F3, causing the clamping member 311 to continue moving into the circumferential extension of the locking groove 2112. The circumferential extension of the locking groove 2112 can restrict the axial movement of the clamping member 311, thereby achieving a secure lock between the locking cover 20 and the fixing chamber 30.

[0068] In summary, after installing the fixed chamber 30 into the mounting box 10, the locking cover 20 is installed on the mounting box, allowing the clamping member 311 of the fixed chamber 30 to extend into the guide groove 2111. The position of the fixed chamber 30 is adjusted along the third direction F3, causing the clamping member 311 to rotate along the direction of the opening of the locking groove 2112. Under the restriction of the circumferential extension of the locking groove 2112, the clamping member 311 can no longer move axially, thereby achieving the locking of the locking cover 20 and the fixed chamber 30, and restricting the radial and axial movement of the fixed chamber 30 on the locking cover 20.

[0069] In one specific embodiment, the first locking part 21 has a first fixing hole 212; the second locking part 31 has a second fixing hole 312, the second fixing hole 312 and the clamping member 311 are arranged circumferentially spaced along the first locking part 21, and the first fixing hole 212 and the second fixing hole 312 are connected to each other so that the locking member 40 extends into the first fixing hole 212 and the second fixing hole 312.

[0070] Specifically, the first fixing hole 212 is provided on the first locking part 21, providing a channel for the locking member 40 to pass through the first locking part 21. The second fixing hole 312 allows the locking member 40 to pass through both the first locking part 21 and the second locking part 31 simultaneously, tightly connecting the two together to form a stable whole, thereby restricting the circumferential rotation of the fixing chamber 30 on the locking cover 20.

[0071] In one specific embodiment, the second guide portion 32 has a rotating rod 321, which is disposed on the outer peripheral surface of the fixed chamber 30 and parallel to the axis of the fixed chamber 30. The rotating rod 321 and the second fixing hole 312 are arranged along the axial direction of the fixed chamber 30.

[0072] Specifically, when installing the fixing chamber 30 into the mounting box 10, the rotating rod 321 can serve as a clear reference point. Since the rotating rod 321 is parallel to the axis of the fixing chamber 30 and arranged axially with the second fixing hole 312 along the axis of the fixing chamber 30, the installation direction and position of the fixing chamber 30 within the mounting box 10 can be initially determined based on the position of the rotating rod 321, ensuring accurate alignment of the second fixing hole 312 with the first fixing hole 212. Rotating the rotating rod 321 causes the fixing chamber 30 to rotate. Because the rotating rod 321 is parallel to the axis of the fixing chamber 30, rotating the rotating rod 321 allows the fixing chamber 30 to rotate smoothly around its axis, thereby achieving adjustment of the installation angle.

[0073] In one specific embodiment, along the radial direction of the first locking portion 21, the clamping member 311 and the second fixing hole 312 form a movable angle in the radial direction of the first locking portion 21.

[0074] Specifically, when the rotating rod 321 drives the fixed chamber 30 (second locking part 31) to rotate, the clamping member 311 has sufficient movement space within the locking groove 2112 and will not interfere with the structure where the second fixing hole 312 is located. The existence of the movement angle allows the fixed chamber 30 to rotate within a certain angle range to achieve alignment between the first fixing hole 212 and the second fixing hole 312. In the embodiment of this application, the clamping member 311 moves a certain distance within the locking groove 2112, and after extending from the clamping member 311 into the guide groove 2111, it begins to rotate. Alignment between the first fixing hole 212 and the second fixing hole 312 is achieved by rotating the rotating rod 321 about 18° along the third direction F3.

[0075] In summary, the fixing chamber 30 is placed into the mounting box 10 along the preset second direction F2, so that both ends of the fixing chamber 30 are tightly abutted against the inner wall of the mounting box 10, thus completing the initial positioning of the fixing chamber 30 within the mounting box 10. The positioning groove 222 on the locking cover 20 is aligned with the protrusion 112 of the first mounting opening 11 of the mounting box 10, and then the locking cover 20 is pushed into the first mounting opening 11 along the first direction F1 until the abutment ring 221 on the locking cover 20 abuts against the abutment ring 111 of the first mounting opening 11 of the mounting box 10. At this point, the protrusion 112 is embedded in the positioning groove 222, thus achieving the positioning of the locking cover 20 on the mounting box 10. Guided by the rotating rod 321 on the outer periphery of the fixed compartment 30, rotating the rotating rod 321 of the fixed compartment 30 causes the fixed compartment 30 to rotate around its axis. This causes the locking member 311 on the inner circumferential surface of the fixed compartment 30 to first enter the guide groove 2111 of the first locking part 21 of the locking cover 20, and then rotate a certain angle (approximately 18°) along the groove opening direction (circumferential direction of the first locking part 21). The locking member 311 then enters the circumferential extension of the locking groove 2112, achieving initial locking. At the same time, the first fixing hole 212 of the first locking part 21 is aligned with the second fixing hole 312 of the second locking part 31. The locking member 40 is inserted from the first fixing hole 212, passing through the first fixing hole 212 and the second fixing hole 312. The locking member 40 is then tightened with a tool to securely connect the locking cover 20 and the fixed compartment 30, completing the installation of the entire battery compartment fixing device.

[0076] In one specific embodiment, the mounting box 10 further has a second mounting opening 12 opened along the second direction F2, and the first fixing hole 212 is disposed opposite to the second mounting opening 12.

[0077] Specifically, the central axis of the second mounting port 12 is spatially orthogonal to the central axis of the first mounting port 11, thus forming a 90° spatial angle between the axial direction of the second mounting port 12 and the axial direction of the first mounting port 11. The second mounting port 12 is an opening for placing the fixing chamber 30 into the mounting box 10. After the locking cover 20 is installed and fixed in the first mounting port 11, the first fixing hole 212 of the locking cover 20 extends into the mounting box 10 as the first locking part 21 moves, and the axial line of the first fixing hole 212 and the second mounting port 12 are aligned on the same straight line. By rotating the rotating rod 321 on the outer periphery of the fixing chamber 30, the fixing chamber 30 is driven to rotate around its own axis. During the rotation, the second fixing hole 312 on the fixing chamber 30 gradually adjusts its position until it is precisely aligned with and connected to the first fixing hole 212. At this time, the axial direction of the second fixing hole 312 is also on the same straight line as the axial direction of the second mounting port 12, and the rotating rod 321 is clearly visible from the frontal view along the second mounting port 12, which facilitates subsequent possible operations or inspections. In this embodiment, the third direction F3 is the direction of rotating the fixing chamber 30, which is the direction of rotation that aligns the second fixing hole 312 on the fixing chamber 30 with the first fixing hole 212 that is on the same straight line as the axial direction of the second mounting port 12.

[0078] Therefore, the battery compartment fixing device 100 provided above, through the design of a device including a mounting box 10, a locking cover 20, a fixing compartment 30, and a locking member 40, allows the fixing compartment 30 to be embedded into the mounting box 10 along the second direction F2, with its two ends abutting against the inner wall of the box, thus restricting movement in the first direction F1; the locking cover 20 is set on the mounting box 10 along the first direction F1 and extends into the fixing compartment 30; the locking member 40 passes through the locking cover 20 and the fixing compartment 30, locking the locking cover 20 and the fixing compartment 30 together to prevent the fixing compartment 30 from moving freely within the mounting box 10. This multi-layered fixing method works together to ensure the initial stable fixing of the fixing compartment 30, preventing any shaking. At the same time, the installation and disassembly processes are simple and quick, requiring no complex tools, greatly improving work efficiency and reducing labor and time costs.

[0079] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
