Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a protective device that facilitates the installation of battery packs. Background Technology

[0002] Large-scale energy storage products have developed rapidly in recent years. The weight and size of energy storage battery packs are constantly expanding, and the weight of individual battery packs is also getting bigger and bigger. Some products can no longer be assembled by manpower alone.

[0003] In existing technologies, due to the increased weight of battery packs, the assembly and transportation of these packs, which are stacked one by one and installed onto the support frame, largely rely on lifting equipment, forklifts, and robots. During assembly, due to physical factors, heavier packs have greater inertia; the resistance is also greater when manually pushing the product into place or during embedded installation. Therefore, when installing heavy or large battery packs, damage to the product or rack often occurs due to collisions and friction between the product and the mounting frame, and may even cause structural bending. Utility Model Content

[0004] To address the aforementioned issues, this application provides a structurally sound protective device that facilitates battery pack installation. This effectively reduces the friction of the battery pack during installation, making the installation process smoother and more efficient, and minimizing or even preventing damage caused by collisions and friction during installation. It is highly versatile and practical.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A protective device for facilitating battery pack installation includes a bracket. Pairs of horizontal beams spaced apart on the left and right sides of the bracket form a support track for the battery pack. Support beams are installed on the left and right sides of the bottom surface of the battery pack. Each support beam has multiple sets of rotating wheels and multiple sets of anti-collision wheels rotatably mounted along its length. The anti-collision wheels are vertically oriented, with their circumferential surfaces protruding outwards from the outer wall of the support beam, and a gap is provided between the anti-collision wheels and their corresponding axles. The rotating wheels are horizontally oriented, with their circumferential surfaces protruding downwards from the outer bottom wall of the support beam, and the rotating wheels and their corresponding axles are an integral structure.

[0007] As a further improvement to the above technical solution:

[0008] The bracket consists of multiple horizontal beams and multiple vertical beams forming two sides, creating a space for accommodating the battery pack; the rotating wheel is rotatably supported on the top surface of the corresponding horizontal beam of the bracket, and the anti-collision wheel is located inside the vertical beam.

[0009] The cross-section of the crossbeam is an inverted "∟" shaped structure. The top surface of the horizontal part of the crossbeam forms a support surface for supporting the battery pack, and the outer wall surface of the vertical part of the crossbeam is attached and fixed to the inner wall surface of the vertical beam.

[0010] The axle of the rotating wheel is rotatably mounted on the support beam, and the rotating wheel and the corresponding axle are glued together to form a relatively fixed integral axle wheel.

[0011] The axle of the anti-collision wheel is welded and fixed to the support beam, and the anti-collision wheel and the corresponding axle are rotatably fitted together to form an axle clearance.

[0012] The length of the crossbeam is greater than the corresponding length of the battery pack. An upwardly positioned stop plate is installed at the rear end of the top surface of the crossbeam, and an energy-absorbing pad is installed at the rear end of the support beam. The energy-absorbing pad is stopped by the stop plate.

[0013] A locking device is installed on the top surface of the crossbeam located in front of the support beam, and the vertical part of the locking device is attached to the front end face of the support beam.

[0014] Both the anti-collision wheels and the swivel wheels are made of nylon.

[0015] The support beam includes a beam body with a square cross-section, a wheel groove on the outer wall of the beam body for the lateral outward mounting of a group of anti-collision wheels, and a wheel groove on the bottom wall of the beam body for the downward outward mounting of a group of rotating wheels.

[0016] The top surface of the support beam extends inward to form a side plate, which is fitted and installed on the bottom surface of the battery pack liquid cooling plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model installs multiple sets of rotating wheels and anti-collision wheels on the support beam at the bottom of the battery pack. When the battery pack is installed onto the support track of the bracket, the rotating wheels and anti-collision wheels can make rotational contact with the bracket, which effectively reduces the friction of the battery pack during installation, making the installation operation smoother and more efficient. It also reduces or even avoids damage caused by collisions and friction during installation. It has strong versatility and good practicality.

[0019] This utility model also has the following advantages:

[0020] By setting the rotating wheel and the corresponding axle as an integrated structure, the load-bearing requirements of the battery pack supported by the rotating wheel on the crossbeam are effectively guaranteed. The rotation of the wheel and the axle at the same angular velocity ensures the integrated rolling forward of the battery pack.

[0021] By arranging the anti-collision wheels with the corresponding axles, the axles provide structural support for the installation of the anti-collision wheels. When the anti-collision wheels contact the bracket, they can rotate while also having a certain amount of movement margin in the horizontal direction, so as to reduce or even avoid collision damage. Furthermore, the anti-collision wheels on the left and right support beams can effectively and reliably fix and limit the battery pack in the bracket in the left and right directions.

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, a protective device for facilitating battery pack installation in this embodiment includes a bracket 1. A pair of horizontal beams 2 spaced apart on the left and right sides of the bracket 1 form a support track for the battery pack 3. Support beams 4 are installed on the left and right sides of the bottom surface of the battery pack 3. Each support beam 4 is rotatably mounted with multiple sets of rotating wheels 6 and multiple sets of anti-collision wheels 5 along its length. The anti-collision wheels 5 are vertically arranged axially, with their circumferential surfaces protruding outwards from the outer wall of the support beam 4. The anti-collision wheels 5 are spaced apart from their corresponding axles. The rotating wheels 6 are horizontally arranged axially, with their circumferential surfaces protruding downwards from the outer bottom wall of the support beam 4. The rotating wheels 6 and their corresponding axles are an integral structure.

[0031] In this embodiment, by installing multiple sets of rotating wheels 6 and anti-collision wheels 5 on the support beam 4 on the bottom surface of the battery pack 3, when the battery pack 3 is fitted onto the support track of the bracket 1, the rotating wheels 6 and anti-collision wheels 5 can make rotational contact with the bracket 1, effectively reducing the friction of the battery pack 3 during installation, making the installation operation smoother and more efficient, and reducing or even avoiding damage caused by collisions and friction during installation.

[0032] In this embodiment, by setting the rotating wheel 6 and the corresponding axle as an integrated structure, the load-bearing requirements of the battery pack 3 supported by the rotating wheel 6 on the crossbeam 2 are effectively guaranteed. The rotation of the wheel and the axle at the same angular velocity ensures the integrated rolling forward of the battery pack.

[0033] In this embodiment, by arranging the anti-collision wheel 5 with the corresponding axle, the axle provides structural support for the installation of the anti-collision wheel 5. When the anti-collision wheel 5 contacts the bracket 1, the anti-collision wheel 5 can rotate while having a certain amount of movement margin in the horizontal direction, so as to reduce or even avoid collision damage. Furthermore, the anti-collision wheels 5 on the left and right support beams 4 can effectively and reliably fix and limit the battery pack 3 in the bracket 1 in the left and right directions.

[0034] In this embodiment, the bracket 1 can be used for temporary placement of the battery pack 3. Figure 1 The simple assembly rack shown can also be a prefabricated rack for installing battery pack 3, such as a prefabricated rack used to stack and install battery pack 3 in a large energy storage container; the bracket 1 can support the battery pack 3, and the battery pack 3 is smoothly installed into the bracket 1 through the protective device.

[0035] The bracket 1 consists of multiple horizontal beams 2 and multiple vertical beams 11 forming two sides, creating a space for accommodating the battery pack 3; the rotating wheel 6 is rotatably supported on the top surface of the corresponding horizontal beam 2 of the bracket 1, and the anti-collision wheel 5 is located inside the vertical beam 11.

[0036] In this embodiment, the bracket 1 can accommodate multiple battery packs 3 vertically via multiple pairs of symmetrical crossbeams 2.

[0037] In this embodiment, the crossbeam 2 is not only a structural component of the bracket 1, but also serves as a support structure for the battery pack 3, simplifying the overall structure and improving space utilization.

[0038] The cross-section of the crossbeam 2 is an inverted "∟" shaped structure. The top surface of the horizontal part of the crossbeam 2 forms the support surface for supporting the battery pack 3. The outer wall surface of the vertical part of the crossbeam 2 is attached and fixed to the inner wall surface of the vertical beam 11. Thus, while accommodating the battery pack 3 inside the bracket 1, the width of the bracket 1 is effectively reduced.

[0039] The axle of the rotating wheel 6 is rotatably mounted on the support beam 4, and the rotating wheel 6 and the corresponding axle are glued together to form a relatively fixed integrated axle wheel.

[0040] In this embodiment, the rotating wheel 6 located on the bottom surface of the support beam 4 has an integrated axle and wheel structure, which is convenient for installation and can effectively reduce friction, thus providing effective protection for the load-bearing and rolling requirements of the battery pack 3.

[0041] In this embodiment, the inner wall of the rotating wheel 6 and the outer circumferential surface of the corresponding wheel axle can be set as a matching concave-convex structure, such as a matching spline structure, combined with adhesive bonding, to effectively ensure the integral nature of the rotating wheel 6 and the wheel axle, and especially to ensure the reliability of its integral rotation.

[0042] The axle of the anti-collision wheel 5 is welded and fixed to the support beam 4. The anti-collision wheel 5 and the corresponding axle are rotatably fitted together and form an axle clearance.

[0043] In this embodiment, the anti-collision wheel 5, which is provided by the axle clearance, can effectively ensure the fixation and positioning between the left and right sides of the battery pack 3 and the bracket 1, and reduce friction and lateral collision by rotating the anti-collision wheel 5 relative to the axle.

[0044] In this embodiment, the inner wall of the anti-collision wheel 5 and the corresponding outer wall of the wheel axle can both be made of smooth circular walls, and a split structure is formed by setting the axle gap.

[0045] like Figure 4 As shown, the length of the crossbeam 2 is greater than the corresponding length of the battery pack 3. A stop plate 9 is installed at the rear end of the top surface of the crossbeam 2, and an energy-absorbing pad 8 is installed at the rear end of the support beam 4. The energy-absorbing pad 8 is stopped by the stop plate 9.

[0046] In this embodiment, the energy-absorbing pad 8 is made of rubber and can be embedded in the tail end of the support beam 4; when the battery pack 3 and the stop plate 9 at the tail end of the crossbeam 2 come into contact, the energy-absorbing pad 8 absorbs the collision stress.

[0047] like Figure 3 As shown, a locking element 7 is installed on the top surface of the crossbeam 2 located in front of the support beam 4, and the vertical part of the locking element 7 is attached to the front end face of the support beam 4.

[0048] In this embodiment, the locking member 7 effectively prevents the battery pack 3 from accidentally moving or sliding relative to the bracket 1 due to the setting of the rotating wheel 6, thus effectively ensuring the fixation of the battery pack 3 within the bracket 1.

[0049] In this embodiment, the locking member 7 can be an L-shaped structural member that is bolted to the crossbeam 2. One end of the L-shaped structural member is attached to the crossbeam 2 and the other end is attached to the front end face of the support beam 4.

[0050] Both the anti-collision wheel 5 and the rotating wheel 6 are made of nylon, which is resistant to impact and provides effective protection for the battery pack 3 itself.

[0051] like Figure 5 and Figure 6 As shown, the support beam 4 includes a beam body 41 with a square cross section. The outer wall of the beam body 41 is provided with wheel grooves 43 for the lateral outward mounting of the group of anti-collision wheels 5, and the bottom wall of the beam body 41 is provided with wheel grooves 43 for the downward outward mounting of the group of rotating wheels 6.

[0052] In this embodiment, by opening the wheel groove 43 on the support beam 4, the installation of the anti-collision wheel 5 and the rotating wheel 6 on the support beam 4 is realized and facilitated, and the structural space of the support beam 4 is effectively utilized to ensure the installation reliability of the anti-collision wheel 5 and the rotating wheel 6.

[0053] In this embodiment, based on the size of the battery pack 3 and other installation requirements, groups of anti-collision wheels 5 and groups of rotating wheels 6 can be arranged along the length of the support beam 4. For example, three groups of rotating wheels 6 can be arranged at intervals in front, middle and back of the bottom of the support beam 4, and anti-collision wheels 5 can be arranged at intervals on the support beam 4 between adjacent groups of rotating wheels 6, so as to effectively ensure and facilitate the installation of the battery pack 3 in the bracket 1.

[0054] The top surface of the support beam 4 extends inward to form a side plate 42, which is attached to the bottom surface of the liquid cooling plate 31 of the battery pack 3.

[0055] In this embodiment, taking the liquid cooling plate 31 located on the bottom surface of the battery pack 3 as the supporting structure of the entire battery pack 3 as an example, the square-shell battery cells inside the battery pack 3 are perfectly fitted and installed on the liquid cooling plate 31; and then a protective device is set on the bottom surface of the liquid cooling plate 31 via the support beam 4.

[0056] In this embodiment, by setting up protective devices on the bottom surface of the battery pack 3, including a rotating wheel 6 protruding from the bottom surface of the support beam 4, an anti-collision wheel 5 protruding from the outer side of the support beam 4, and an energy-absorbing pad 8 on the rear end surface of the support beam 4, the inertial collisions generated in the front-back and left-right directions during the installation of the battery pack 3 on the bracket 1 can be effectively absorbed and resolved, thereby reducing the probability of damage during installation, effectively simplifying the operation process, and ensuring that the battery pack 3 is installed smoothly, easily, and conveniently in the bracket 1.

[0057] This invention effectively reduces the friction of the battery pack during installation, making the installation operation smoother and more efficient, and reducing or even avoiding damage caused by collisions and friction during installation. It is highly versatile and practical.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
