Description

Technical Field

[0001] The utility model relates to the technical field of battery pack production and manufacturing, in particular to a general battery pack lifting tooling. Background Technique

[0002] A battery pack refers to an assembly formed by combining multiple single cells in series, parallel, or a combination of both. It not only includes the battery cells themselves but also components such as a battery management system, a thermal management system, electrical connectors, protection devices, and a housing. Battery packs are widely used in various devices that require power storage and supply, especially in fields such as electric vehicles and energy storage systems. With the development of technology, the design of battery packs is becoming more compact and efficient, while also continuously improving their safety, reliability, and economy. This is crucial for promoting the development of electric vehicles and other fields that rely on battery technology.

[0003] During the production and assembly of battery packs, it is inevitable to lift and transfer the battery packs. Different models of battery packs have different lifting holes and lifting positions, and it is impossible to achieve stable fixation through safety buckles and seat belts. Therefore, it is necessary to install lifting tooling during lifting. However, for the production of each model of battery pack, a corresponding lifting tooling needs to be designed and manufactured, which results in a large number of types of lifting tooling. After production, the lifting tooling is idle and cannot be reused, resulting in an increase in the production cost of battery packs. Summary of the Utility Model

[0004] In view of this, the utility model aims to propose a general battery pack lifting tooling with a wider application range, which can adapt to battery packs with different lifting hole types and lifting positions, so as to achieve the purpose of compressing and controlling the production cost of battery packs.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] A general battery pack lifting tooling of the utility model includes an adjustment component connected to a lifting device;

[0007] A support component configured to be connected to the adjustment component and symmetrically distributed in two groups;

[0008] A locking component configured to be slidably arranged in multiple groups on the support component;

[0009] The distance between the two groups of support components changes due to the adjustment of the adjustment component.

[0010] Further, the adjustment component includes an adjustment slide rail;

[0011] Sliders, two of which are arranged to be slidably connected to the adjustment slide rail;

[0012] Each of the two sliders is connected to a set of the support components.

[0013] Furthermore, the adjusting components are provided in multiple sets, and the adjusting slide rails of the multiple sets of adjusting components are distributed in parallel with each other.

[0014] Furthermore, a displacement sensor is provided on the slider for detecting the relative position between the slider and the adjusting slide rail.

[0015] Furthermore, the support component includes a base fixedly provided at the bottom of the slider;

[0016] A support beam is provided at the bottom of the base along a direction perpendicular to the adjusting slide rail;

[0017] A support slide rail is provided below the support beam along a direction parallel to the support beam;

[0018] The locking component is slidably provided on the support slide rail.

[0019] Furthermore, the support component further includes a connecting member;

[0020] One end of the connecting member is connected to the support beam, and the support slide rail is fixedly provided on the connecting member.

[0021] Furthermore, the base is slidably provided along the length direction of the support beam and can be fixed at any position within the sliding stroke.

[0022] Furthermore, the locking component includes a claw slidably provided on the support slide rail;

[0023] A handle is rotatably provided on the claw;

[0024] A connecting shaft is slidably provided on the claw along a direction perpendicular to the support slide rail and is hinged to one end of the handle close to the claw;

[0026] Furthermore, a convex portion is provided on a surface of the claw that fits the support slide rail;

[0027] The surface of the support slide rail has a groove adapted to the shape of the convex portion.

[0028] Furthermore, the pin shaft and the connecting shaft can be detachably connected.

[0029] Compared with the prior art, the present utility model has the following advantages:

[0030] The general battery pack lifting tooling described in the present utility model is structured by combining an adjustment component, a support component, and a locking component. The locking component can lock and fix the battery pack. While the support component provides support and limitation for the locking component, the distance between the two locking components slidably arranged on the support component can be adjusted according to actual needs. Both support components are connected to the adjustment component. Therefore, the distance between the locking components arranged on different support components can be adjusted through the adjustment component. Since the distances in two directions of multiple locking components can be adjusted, compared with the existing special lifting tooling, the general battery pack lifting tooling in this application has a wider applicable range, can adapt to the lifting requirements of different models of battery packs, and achieves the invention purpose of reducing the production cost of battery packs.

[0031] In addition, by setting the adjustment component as a structure of a slider and an adjustment slide rail, the adjustment of the distance between the support components can be achieved by the relative sliding between the slider and the adjustment slide rail, so as to adjust the distance between the locking components installed on the support components to achieve the invention purpose of adapting to different sizes of battery packs.

[0032] By increasing the number of adjustment components, the number of connection points between the same support component and the adjustment component is increased. Compared with single-point connection, the multi-point connection structure has more advantages in terms of attitude stability during the lifting state, thus achieving the invention purpose of improving the stability of the battery pack lifting process.

[0033] By setting a displacement sensor on the slider, it is convenient for the staff to master the sliding distance of the slider and the distance between the two support components, so that fine adjustment can be made according to the actual situation, achieving the invention purpose of simplifying the lifting operation process.

[0034] Secondly, by setting the support component as a structure of a base, a support beam, and a support slide rail, the base plays a role of limiting and fixedly connecting the slider. The support beam connects the base and the support slide rail and plays a role of fixing the support slide rail. The locking component is slidably arranged on the support slide rail, which can drive the locking component to move and can adjust the distance between the locking components themselves by sliding, so as to adapt to different sizes of battery packs.

[0035] By arranging a connecting piece between the support beam and the support slide rail, the stability and load-bearing capacity of the connection structure between the support slide rail and the support beam can be further improved, so that the support beam or the support slide rail is not prone to deformation and dislocation after bearing the load, which is beneficial to improving the stability during the battery pack lifting process.

[0036] By setting a sliding connection structure between the base and the support beam so that the base can be fixed at any position within its sliding stroke with respect to the support beam, the distance between the adjustment components can be adaptively adjusted according to the center of gravity distribution of battery packs of different models, thereby further enhancing the stability during the hoisting process of the battery pack and achieving the inventive purpose of improving applicability.

[0037] By providing a clamping structure with a protrusion and a groove between the clamping jaw and the support slide rail, the stability of the support effect of the support slide rail on the clamping jaw can be further improved, thereby achieving the inventive purpose of further enhancing the stability during the hoisting process of the battery pack.

[0038] By adopting a detachable connection structure between the pin shaft and the connecting shaft, the staff can change the cross-sectional shape of the pin shaft by disassembling and replacing different pin shafts, thereby adapting to different hoisting hole types of battery packs of different models and achieving the inventive purpose of expanding the scope of application.

[0050] The following will refer to the attached Figure 1 to the attached Figure 4 and in combination with the embodiments to detail the present utility model.

[0051] This embodiment relates to a general battery pack lifting tooling. By adopting a locking mechanism arranged in a sliding manner to tightly support the battery pack and using an adjusting component and a supporting component to adaptively adjust the distance and relative position of the locking component, it can be adapted to different models of battery packs with different lifting hole positions. Therefore, this application has a wider scope of application and can be reused in the production and lifting of battery packs of different models and batches, achieving the invention purpose of compressing and controlling the production cost of the battery pack.

[0052] In terms of the overall structure, the general battery pack lifting tooling of this embodiment includes an adjusting component 1, a supporting component 2, and a locking component 3. Among them, the adjusting component 1 is connected to the lifting equipment through a rectangular metal plate with multiple lifting rings. The number of the supporting components 2 is two groups. The two groups of supporting components 2 are symmetrically and parallelly arranged with each other and are both connected to the adjusting component 1. Under the adjustment of the adjusting component 1, the distance between the two groups of supporting components 2 changes. Two groups of locking components 3 are installed on each group of supporting components 2. The locking component 3 is slidably arranged between the supporting component 2. The distance between the two locking components 3 on the same group of supporting components 2 can be slidably adjusted according to actual needs.

[0053] With the above settings, by setting the lifting tooling into a structure composed of the adjusting component 1, the supporting component 2, and the locking component 3, the locking component 3 among them can lock and fix the battery pack. While the supporting component 2 provides support and limit for the locking component 3, the distance between the two locking components 3 slidably arranged on the supporting component 2 can be adjusted according to actual needs. Both of the two supporting components 2 are connected to the adjusting component 1. Therefore, the distance between the locking components 3 arranged on different supporting components 2 can be adjusted through the adjusting component 1. Since the distances in two directions of multiple locking components 3 can be adjusted, compared with the existing special lifting tooling, the general battery pack lifting tooling in this application has a wider scope of application, can adapt to the lifting requirements of different models of battery packs, and achieves the invention purpose of reducing the production cost of the battery pack.

[0054] Based on the above design concept, specifically, in this embodiment, referring to Figure 1 and Figure 2 , the adjusting component 1 includes an adjusting slide rail 101 and a slider 102. Two sliders 102 are arranged on the upper slide rail of the adjusting slide rail 101. Each slider 102 is connected to a group of supporting components 2. When the slider 102 slides relative to the adjusting slide rail 101, it can drive the supporting component 2 connected to the slider 102 to move together, so as to realize the adjustment of the distance between the supporting components 2. The relative position of the slider 102 and the adjusting slide rail 101 can be fixed through a fastening bolt to ensure that there is no slipping and dislocation during the lifting process.

[0055] By setting the structure of the adjusting component 1 with the slider 102 and the adjusting slide rail 101, the adjustment of the distance between the support components 2 can be achieved by means of the relative sliding between the slider 102 and the adjusting slide rail 101, so that the distance between the locking components 3 installed on the support components 2 can be adjusted to achieve the invention purpose of adapting to battery packs of different sizes.

[0056] Referring to Figure 1 and Figure 2 , for the purpose of improving the stability of the battery pack during the hoisting process, the number of the adjusting components 1 can be multiple groups. In this embodiment, the number of the adjusting components 1 is two groups. The adjusting slide rails 101 of the two groups of adjusting components 1 are arranged parallel to each other. The two sliders 102 on the same side of the two groups of adjusting components 1 are respectively connected to both ends of the same support component 2.

[0057] By increasing the number of the adjusting components 1, the number of connection points between the same support component 2 and the adjusting components 1 is increased. Compared with single-point connection, the multi-point connection structure has more advantages in terms of attitude stability in the hoisting state, thus achieving the invention purpose of improving the stability of the battery pack during the hoisting process.

[0058] Referring to Figure 1 and Figure 2 , in order to simplify the hoisting operation process, in this embodiment, a displacement sensor is installed on the slider 102. The displacement sensor can be electrically connected to a controller with a display terminal for detecting the relative position between the slider 102 and the adjusting slide rail 101.

[0059] By setting a displacement sensor on the slider 102, it is convenient for the staff to master the sliding distance of the slider 102 and the distance between the two support components 2, so that fine adjustment can be made according to the actual situation, achieving the invention purpose of simplifying the hoisting operation process.

[0060] Referring to Figure 1 and Figure 3 , in this embodiment, the support component 2 includes a base 201, a support beam 202 and a support slide rail 203. Among them, the base 201 is arranged at the bottom of the slider 102 and is fixedly connected to the slider 102. The number of the bases 201 is the same as that of the sliders 102, and the installation positions correspond one by one. The support beam 202 is fixedly arranged at the bottom of the base 201 along the direction perpendicular to the adjusting slide rail 101. The support slide rail 203 is arranged in parallel below the support beam 202. The locking component 3 is slidably arranged on the support slide rail 203.

[0061] By setting the support component 2 as a structure of a base 201, a support beam 202, and a support slide rail 203, the base 201 among them plays a role in limiting and fixedly connecting the slider 102. The support beam 202 connects the base 201 and the support slide rail 203, playing a role in fixing the support slide rail 203. A locking component 3 is slidably arranged on the support slide rail 203, which can drive the locking component 3 to move, and the distance between the locking components 3 themselves can be adjusted by sliding, so as to adapt to battery packs of different sizes.

[0062] Referring to Figure 1 and Figure 3 , in order to improve the stability between the support beam 202 and the support slide rail 203, in this embodiment, a connecting piece 204 is arranged between the support beam 202 and the support slide rail 203. The connecting piece 204 includes a connecting plate parallel to the support beam 202 and two connecting rods perpendicular to the support beam 202. The connecting rods are perpendicularly connected to the bottom of the support beam 202, and the connecting plate is fixedly connected to the two connecting rods. The support slide rail 203 is fixedly arranged on the upper surface of the connecting plate.

[0063] By arranging the connecting piece 204 between the support beam 202 and the support slide rail 203, the stability and load-bearing capacity of the connection structure between the support slide rail 203 and the support beam 202 can be further improved, so that the support beam 202 or the support slide rail 203 is not easily deformed and displaced after bearing the load, which is beneficial to improving the stability during the hoisting process of the battery pack.

[0064] Referring to Figure 1 and Figure 3 , for the purpose of expanding the application scope of this application, in this embodiment, the base 201 and the support beam 202 are installed in a sliding connection manner. The base 201 can be fixed at any position within its sliding stroke between it and the support beam 202.

[0065] By setting the connection between the base 201 and the support beam 202 as a sliding connection structure where the base 201 can be fixed at any position within its sliding stroke between it and the support beam 202, the distance between the adjusting components 1 can be adaptively adjusted according to the center-of-gravity distribution of battery packs of different models, thereby further improving the stability during the hoisting process of the battery pack and achieving the invention purpose of improving applicability.

[0066] Referring to Figure 1 and Figure 4, in this embodiment, the locking assembly 3 includes a claw 301, a handle 302, a connecting shaft 303, and a pin shaft 304. Among them, the claw 301 is slidably arranged on the support slide rail 203 and can be fixed at any position in its sliding stroke with the support slide rail 203. The handle 302 is rotatably arranged on the claw 301 by means of hinge. The connecting shaft 303 is slidably arranged on the claw 301 along a direction perpendicular to the support slide rail 203. One end of the connecting shaft 303 is hinged to one end of the handle 302 close to the claw 301. The staff can drive the connecting shaft 303 to slide along a direction perpendicular to the support slide rail 203 by pulling the handle 302. The pin shaft 304 is an "L"-shaped metal rod. One end of the pin shaft 304 is connected to the end of the connecting shaft 303 far from the handle 302, and the cross-sectional shape of the other end of the pin shaft 304 is the same as the hole shape of the lifting hole on the battery pack.

[0067] By setting the locking assembly 3 as a structure composed of a claw 301, a handle 302, a connecting shaft 303, and a pin shaft 304, the staff can drive the connecting shaft 303 to slide along a direction perpendicular to the support slide rail 203 by pulling the handle 302, and then drive the pin shaft 304 to slide into or out of the lifting hole of the battery pack along a direction perpendicular to the support slide rail 203, so as to lock or unlock the battery pack.

[0068] Refer to Figure 1 and Figure 4 , in order to further improve the stability during the lifting of the battery pack, in this embodiment, a convex portion is provided on the surface of the claw 301 that fits the support slide rail 203. Correspondingly, a groove with a cross-sectional shape adapted to that of the convex portion is also provided on the surface of the support slide rail 203.

[0069] By providing a clamping structure of a convex portion and a groove between the claw 301 and the support slide rail 203, the stability of the support effect of the support slide rail 203 on the claw 301 can be further improved, thus achieving the invention purpose of further improving the stability during the lifting of the battery pack.

[0070] Refer to Figure 1 and Figure 4 , for the purpose of expanding the application scope of this application, in this embodiment, the pin shaft 304 and the connecting shaft 303 are detachably connected by means of threaded connection.

[0071] By adopting a detachable connection structure between the pin shaft 304 and the connecting shaft 303, the staff can change the cross-sectional shape of the pin shaft 304 by disassembling and replacing different pin shafts 304, so as to adapt to different lifting hole shapes of different models of battery packs, thus achieving the invention purpose of expanding the application scope.
