Description

Technical Field

[0001] This disclosure relates to a battery installation simulation unit and a battery installation simulation component. Background Technology

[0002] In new energy vehicles, battery packs are required to provide power. These battery packs are typically installed at the bottom of the vehicle body. The usual method of mounting is using mounting holes on the vehicle body and corresponding fasteners on the battery pack, or individual fasteners (such as bolts, fixing rods, etc.), to install and secure the battery pack to the vehicle body. Therefore, the positioning accuracy of the mounting holes on the vehicle body is crucial. If the positioning accuracy of the mounting holes on the vehicle body is substandard, it cannot be guaranteed that the mounting hole can be matched with the corresponding fastener on the battery pack, which will make it difficult or even impossible to install the battery pack onto the vehicle body.

[0003] To check the positioning of the battery mounting holes on the vehicle body, during the verification phase of vehicle production or in the subsequent quality inspection after mass production, technicians in the body welding workshop usually use a coordinate measuring machine to check the size of the mounting holes.

[0004] However, although coordinate measuring machines (CMMs) can perform very precise inspection processes, the inspections they perform are often very time-consuming for the following reasons. First, common CMMs use only a single measuring arm and a probe mounted on it to perform the inspection process, thus they cannot inspect multiple mounting holes simultaneously. Second, the number of mounting holes for batteries on the body of new energy vehicles often reaches 50 to 70. Third, in order to obtain sufficiently accurate inspection results, the inspection speed of each mounting hole by the CMM is usually also slow. Therefore, due to these reasons, under normal circumstances, for only one vehicle being inspected, the entire process of the CMM on-site, from the start of the inspection to the final inspection report, often takes 4 to 6 hours, resulting in very low inspection efficiency.

[0005] During the production verification phase, repeated adjustments to the equipment may be necessary, which may lead to frequent inspections of trial-assembled vehicles. In the daily quality sampling inspection phase, it may be desirable to inspect multiple vehicles sequentially and quickly. Coordinate measuring machines, which have lower inspection efficiency, may not be able to meet such requirements. Utility Model Content

Detailed Implementation

[0029] The present disclosure will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure more complete and to fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments.

[0030] It should be understood that the same reference numerals denote the same elements in all the accompanying drawings. For clarity, the dimensions of certain features may be modified in the drawings.

[0031] It should be understood that the terminology used in this specification is for describing specific embodiments only and is not intended to limit this disclosure. All terms used in this specification (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0032] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features. The term “and / or” used in this specification includes any and all combinations of one or more of the related listed items. The terms “between X and Y” and “between approximately X and Y” used in this specification should be interpreted as including both X and Y. The term “between approximately X and Y” used in this specification means “between approximately X and approximately Y,” and the term “from approximately X to Y” used in this specification means “from approximately X to approximately Y.”

[0033] In the specification, when an element is described as being "on," "attached," "connected," "coupled," or "in contact" with another element, the element can be directly located on, attached to, connected to, coupled to, or in contact with the other element, or there may be intermediate elements present.

It should be understood that spatial relation terms include not only the orientation shown in the drawings but also the different orientations of the device during use or operation. For example, when the device in the drawings is inverted, a feature previously described as "below" other features can now be described as "above" other features. The device can also be oriented in other ways (rotated 90 degrees or in other orientations), in which case the relative spatial relationships will be explained accordingly.

[0035] See Figure 1 The diagram illustrates a battery mounting simulation unit 1000 according to the present disclosure. The battery mounting simulation unit 1000 is adapted to fit into the body of a vehicle under test for checking the dimensional accuracy of mounting holes for battery components on the body.

[0036] The battery installation simulation unit 1000 includes a main frame 100, at least two main locating pins 400 and at least one non-threaded hole inspection assembly 200.

[0037] The main frame 100 serves as the load-bearing body for the battery installation simulation unit 1000. The main frame 100 includes two parallel side beams 10 and at least one first connecting beam 40. The first connecting beam 40 extends perpendicularly between the two side beams 10. In this embodiment, each side beam 10 and the first connecting beam 40 is generally elongated plate-shaped, but it is understood that other beam forms may be used depending on design requirements.

[0038] At least two main positioning pins 400 are disposed on the main frame 100. The main positioning pins 400 serve as positioning reference points when the battery installation simulation unit 1000 is engaged with the vehicle body under test, thereby fixing the overall position of the battery installation simulation unit 1000 relative to the vehicle body under test. When the battery installation simulation unit 1000 is engaged with the vehicle body under test, the main positioning pins 400 are first inserted into the corresponding positioning holes on the vehicle body under test.

[0039] refer to Figure 2 The image shows a front view of a non-threaded hole inspection assembly 200. The non-threaded hole inspection assembly 200 is used to inspect the positioning accuracy of non-threaded mounting holes for battery assemblies on a vehicle body under test. Non-threaded holes can be plain holes, countersunk holes, blind holes, etc.

[0040] Each non-threaded hole inspection assembly 200 includes a bracket portion 120, at least one inspection rod member 220, and an observation opening 290.

[0041] The bracket portion 120 is used to support the inspection rod member 220, the observation opening 290, and additional components of the non-threaded hole inspection assembly 200. The bracket portion 120 has a body 125 and a receiving space 140 located within the body 125 (see...). Figure 3 ).

[0042] See Figure 3 It shows along Figure 2 The image shows a cross-sectional view of one of the inspection rod members 220 of the non-threaded hole inspection assembly 200, taken from line AA. The inspection rod member 220 is a main component used to check the positioning accuracy of non-threaded holes on the vehicle body under test.

[0043] As shown in the figure, the inspection rod component 220 includes a rod body 225 that can move through the main body 125 and a reset member 250.

[0044] The rod body 225 is a generally cylindrical rod. The rod body 225 is the component in the inspection rod assembly 220 that directly interacts with the vehicle body under test. The rod body 225 is movable through the body 125 of the bracket portion 120. The rod body has a top end 228 and an opposing bottom end 229. The position of each rod body 225 relative to the aforementioned at least two main locating pins 400 is configured to correspond to the position of a corresponding non-threaded hole with a predetermined positional tolerance range on the vehicle body under test relative to a locating hole on the vehicle body under test. In other words, the positioning of the rod body 225 on the main frame 100 simulates the positioning of a corresponding fastener on the battery assembly that will be mated to the vehicle body.

[0045] The reset member 250 applies an upward force to the rod body 225 and holds the rod body 225 in place as follows. Figure 2 and Figure 3The first position is shown in the diagram. The reset member 250 is used to apply force to the rod body 225 to cause the rod body 225 to tend to return to the first position.

[0046] Each non-threaded hole inspection assembly 200 has an observation opening 290 provided on the body 125 of the bracket portion 120 and leading to the receiving space 140. The observation opening 290 allows the user of the battery mounting simulation unit 1000 to observe the situation inside the receiving space 140 through the observation opening 290, as will be described in detail below.

[0047] In the use of the battery installation simulation unit 1000, when the battery installation simulation unit 1000 is fitted to the vehicle body under test, when the position of the non-threaded hole on the vehicle body is within the predetermined position tolerance range (that is, when it has the expected positioning accuracy on the vehicle body), the rod body 225 corresponding to the non-threaded hole is held in the aforementioned first position and inserted into the non-threaded hole; conversely, when the position of the non-threaded hole is not within the predetermined position tolerance range (that is, when it does not have the expected positioning accuracy on the vehicle body), the non-threaded hole and the corresponding rod body 225 cannot be aligned, so the rod body 225 is pressed down by the vehicle body part near the non-threaded hole, thereby forcing the rod body 225 to move downward so that the bottom end 229 of the rod body 225 enters the receiving space 140. At this time, the user can easily observe the bottom end 229 of the rod body 225 entering the receiving space 140 by observing the opening 290, thereby determining that the positioning accuracy of the non-threaded hole on the vehicle body under test corresponding to the rod body 225 is unqualified.

[0048] The bottom end 229 of the rod body 225 may preferably be coated with a visually noticeable pigment (e.g., red pigment) to help the user quickly identify whether there are any non-threaded holes on the vehicle body under test.

[0049] exist Figure 1 The embodiment shown depicts a main frame 100 of the battery mounting simulation unit 1000 having five first connecting beams 40 and illustrating the spacing between them. However, it is understood that, without departing from the scope of this disclosure, the main frame 100 may have other numbers of first connecting beams 40 and different spacing patterns between the first connecting beams 40, depending on the arrangement of the mounting holes on the specific vehicle body under test. Similarly, the number of non-threaded hole inspection components 200 on each first connecting beam 40 and the number of inspection rod members 220 included in each non-threaded hole inspection component 200 may also vary depending on the different arrangements of the mounting holes on the vehicle body under test.

[0050] In addition, although Figure 1As shown, the battery installation simulation unit 1000 has two main positioning pins 400, but those skilled in the art will understand that the battery installation simulation unit 1000 may also have more than two main positioning pins 400.

[0051] like Figure 3 As shown, the main body 125 of the bracket portion 120 of the non-threaded hole inspection assembly 200 may have a top portion 127, a bottom portion 130, and a connecting wall 133 connecting the top portion 127 and the bottom portion 130. Each inspection rod member 220 may further include: an upper support 227 that engages with the top portion 127; and a lower support 230 that engages with the bottom portion 130. The rod body 225 is movable through the upper support 227 and the lower support 230. A reset member 250 may engage between the lower support 230 and the rod body 225. Specifically, the reset member 250 may engage between the lower support 230 and a step formed on the rod body 225, such as... Figure 3 As shown.

[0052] In this embodiment, the reset element 250 takes the form of a helical spring surrounding the rod body 225, but it is understood that other devices capable of achieving reset are also feasible, such as cylinders, hydraulic cylinders, etc.

[0053] The battery installation simulation unit 1000 may also include at least one threaded hole inspection component 300. The threaded hole inspection component 300 facilitates the user to inspect the threaded holes on the vehicle body under test using hand tools.

[0054] Since the threaded holes on the vehicle body have threads, and threads have only a limited degree of hardness, if the inspection rod member 220 of the aforementioned non-threaded hole inspection assembly 200 is used to inspect the threaded holes, there is a risk that the threads of the threaded holes will be damaged by the rod body 225. Therefore, a threaded hole inspection assembly 300 can be specially provided to inspect the corresponding threaded holes.

[0055] like Figure 1 As shown, each threaded hole inspection assembly 300 includes a bracket 330 and an inspection hole 350 aligned with the corresponding threaded hole on the vehicle body to be tested.

[0056] See Figure 4 The image shows a side view of the threaded hole inspection assembly 300. A bracket 330 is used to support the threaded hole inspection assembly 300. The bracket 330 has a top plate 333 and legs 335 that support the top plate on the side beams 10 of the main frame 100.

[0057] Inspection holes 350 are used to allow suitable tools to pass through them to access corresponding threaded holes on the vehicle body when the battery mounting simulation unit is fitted to the vehicle body under test, for checking the positioning accuracy of the threaded holes. Inspection holes 350 are located on the top plate 333. Similar to the configuration of the rod body 225, the position of each inspection hole 350 relative to the at least two main locating pins 400 is configured to correspond to the position of the corresponding threaded hole with a predetermined positional tolerance on the vehicle body under test relative to the locating hole on the vehicle body under test. That is, the positioning of each inspection hole 350 on the main frame 100 also simulates the positioning of the corresponding fastener on the battery assembly to be fitted to the vehicle body.

[0058] When the battery installation simulation unit 1000 is fitted onto the vehicle body under test, if the position of the threaded hole is within the predetermined positional tolerance range, the corresponding inspection hole 350 aligns with the threaded hole. At this time, the user can use a tool (such as a go / no-go gauge) to pass through the inspection hole 350 into the threaded hole and inspect it. However, if the position of the threaded hole is not within the predetermined positional tolerance range, the corresponding inspection hole 350 is not aligned with the threaded hole. In this case, the user cannot use a tool to pass through the inspection hole 350 into the threaded hole, thus indicating that the positioning of the threaded hole on the vehicle body is unqualified. It should be noted that when the position of the threaded hole is within the predetermined positional tolerance range, the user can also use tools to check parameters of the threaded hole other than positioning accuracy, such as hole diameter and hole depth. Figure 4 The diagram illustrates a scenario where a go / no-go gauge 3000 is used to pass through inspection hole 350.

[0059] At least one bracket portion 120 of a non-threaded hole inspection assembly 200 may be disposed on at least one first connecting beam 40.

[0060] refer to Figure 1 The main frame 100 may also include a front beam 60 and a rear beam 80. The front beam 60 connects the front ends of the two side beams 10 together, while the rear beam 80 connects the rear ends of the two side beams 10 together. The front beam 60 and the rear beam 80 are used to increase the rigidity of the entire main frame 100 and allow for the installation of additional non-threaded hole inspection assemblies 200 and / or threaded hole inspection assemblies 300.

[0061] In an embodiment where the main frame 100 has a front beam 60 and a rear beam 80, at least two main locating pins 400 may be provided, one on the front beam 60 and the other on the rear beam 80.

[0062] The main frame 100 may further include at least one second connecting beam 90. The second connecting beam 90 is perpendicular to the rear beam 80 and at least one first connecting beam 40, connecting the rear beam 80 and the first connecting beam 40 together. At least one non-threaded hole inspection assembly 200 may include a plurality of non-threaded hole inspection assemblies 200. The bracket portion 120 of at least one of the plurality of non-threaded hole inspection assemblies 200 is disposed on the at least one second connecting beam 90. The second connecting beam 90 allows for the installation of additional non-threaded hole inspection assemblies 300. Although in Figure 1 In the embodiment shown, a second connecting beam 40 is connected between the rear beam 80 and the first connecting beam 40. However, it is understood that, without departing from the scope of this disclosure, when the main frame 100 has two or more first connecting beams 40, the second connecting beam 40 may also be configured to connect two adjacent first connecting beams 40 that are spaced apart.

[0063] Continue to refer to Figure 1 The battery installation simulation unit 1000 may further include at least one parallelism checking component 500. The parallelism checking component 500 facilitates the detection of the parallelism of the vehicle body surfaces when the battery installation simulation unit 1000 is fitted to the vehicle body under test. Each parallelism checking component 500 extends from the main frame 100 and has a horizontally arranged reference plane plate 520. When the battery installation simulation unit 1000 is fitted to the vehicle body under test, the parallelism checking component 500 allows the parallelism of the vehicle body surfaces under test to be checked with reference to the reference plane plate 520.

[0064] Specifically, when the battery installation simulation unit 1000 is fitted to the vehicle body under test, the reference plane plate 520 is positioned adjacent to the test surface of the vehicle body and offset vertically from the test surface. At this time, the user can use a parallelism measuring instrument, placing one end of the instrument against the reference plane plate 520 and the other end against the test surface. Since the reference plane plate 520 is a horizontally arranged plate, it can be used as a reference surface to check the difference in parallelism between the test surface and the reference plane plate 520 using the measuring instrument, thereby measuring whether the parallelism of the test surface is acceptable.

[0065] refer to Figure 5 and Figure 6 This disclosure also proposes a battery installation simulation assembly. The battery installation simulation assembly includes... Figure 5 The installation trolley 2000 and the aforementioned battery installation simulation unit 1000 are shown. Figure 6 As shown, the installation trolley 2000 is used to carry the battery installation simulation unit 1000 when using the battery installation simulation assembly, provides the function of raising and lowering the battery installation simulation unit 1000, and allows for convenient transportation of the battery installation simulation unit 1000.

[0066] The trolley 2000 includes a trolley body 600, wheels 700, and a lifting mechanism 800.

[0067] The trolley body 600 serves as the main structure to support and mount other components of the trolley 2000. The trolley body has a top portion 620 and a bottom portion 640. (Example...) Figure 5 As shown, the trolley body 600 can be in the form of a frame composed of interconnected rod-like members, but those skilled in the art will understand that the trolley body 600 can also be formed as a shell covered with a skin or even a substantially solid component.

[0068] Wheels 700 are provided at the bottom end 640 of the trolley body 600 for moving the mounting trolley 2000. Although the wheels 700 are shown in the embodiment as four wheels located at the four corners of the bottom end 640 of the trolley body 600 as shown in the figure, the wheels 700 may also be provided as three wheels located at three positions in a roughly triangular arrangement at the bottom end 640, or as more than four wheels located at more than four positions at the bottom end 640, such as six, eight, ten, etc.

[0069] The lifting mechanism 800 is used to support the aforementioned battery installation simulation unit 1000 and enable it to be raised and lowered. The lifting mechanism 800 is located at the top end 620 of the trolley body 600. The lifting mechanism 800 includes a support plate 820 and a lifting part 860.

[0070] The support plate 820 is used to directly support the battery mounting simulation unit 1000. The support plate 820 has an upper surface for placing the battery mounting simulation unit 1000.

[0071] The lifting unit 860 supports the support plate 820 on the top part 620 and enables the support plate 820 to move in the vertical direction (i.e., to rise and fall).

[0072] A battery installation simulation assembly according to this disclosure is formed by placing the battery installation simulation unit 1000 on the support plate 820 of the installation trolley 2000. The user can conveniently move the battery installation simulation unit by pushing the installation trolley 2000. When it is necessary to inspect the mounting holes on the vehicle body under test, the battery installation simulation assembly is pushed under the vehicle body, and then the lifting device 800 is operated to raise the support plate 820 so that the battery installation simulation unit 1000 can mate with the vehicle body under test. After the inspection is completed, the lifting device 800 can be operated to lower the support plate 820, thereby disengaging the battery installation simulation unit 1000 from the vehicle body under test.

[0073] The lifting mechanism 800 may also include a translation device. When fitted to the vehicle body under test, the weight of the battery installation simulation component may make fine-tuning of its position relative to the vehicle body difficult, potentially preventing the main locating pin 400 of the battery installation simulation unit 1000 from being inserted into the locating hole on the vehicle body. The translation device allows the battery installation simulation unit 1000, placed on the support plate 820, to slide and translate, allowing for slight adjustments to its position on the support plate 820, thereby enabling faster insertion of the main locating pin 400 into the locating hole on the vehicle body.

[0074] The translation device includes a plurality of balls 880 disposed on the upper surface of the support plate 820. The balls 880 allow the battery-mounted simulation unit 1000, which is placed on the upper surface, to slide and translate on that surface. (Reference) Figure 7 It shows a cross-sectional view of the translation device and details of the contact between the ball bearing 880 and the battery mounting simulation unit 1000.

[0075] The translation device may also include a plurality of locking parts 890 disposed on the outer periphery of the support plate 820. The locking parts are used to optionally limit the sliding range of the battery installation simulation unit 1000 on the upper surface of the support plate 820 to prevent the risk of the battery installation simulation unit 1000 sliding excessively and falling off the installation trolley 1000.

[0076] Each locking part 890 has a locking hole. The locking hole allows the bottom end of a locking pin to be inserted therein, and can optionally lock the bottom end of the locking pin. The top end of the locking pin, opposite the bottom end, can be inserted into a corresponding hole provided on the side beam 40 of the battery-mounted simulation unit 1000. Figure 6 As shown in circles A and B.

[0077] When the locking pins are inserted into the locking holes of the locking part 890 and the corresponding holes of the battery installation simulation unit 1000 at both ends, and the locking holes lock the bottom end of the locking pins, the battery installation simulation unit 1000 will be firmly fixed to the support plate 820 and cannot move. When the locking pins are inserted into the locking holes of the locking part 890 and the corresponding holes of the battery installation simulation unit 1000 at both ends, but the locking holes do not lock the bottom end of the locking pins, the battery installation simulation unit 1000 can slide on the support plate 820 to a certain extent, depending on the degree of freedom designed for the bottom end of the locking pin in the locking hole.

[0078] refer to Figure 5The lifting unit 860 may include a worm gear assembly 870 and a handle 865 connected to the worm gear assembly 870. The worm gear assembly 870 telescopically supports the support plate 820. By operating the handle 865, the worm gear assembly 870 can raise or lower the support plate 820. Specifically, the worm gear assembly 870 has a worm connected to the support plate 820. By means of the mutual movement between the worm gear and the worm, the worm can move relative to the worm gear, thereby driving the support plate 820 to rise or fall. In the embodiment, corresponding worms are shown provided at the four corners of the support plate 820, but it is understood that different numbers of worms can also be provided at different positions on the support plate 820 without departing from the scope of this disclosure.

[0079] The mounting trolley 2000 may also include a support bracket 900 for supporting at least a portion of the vehicle body under test. The support bracket 900 is positioned at the four corners of the trolley body 600 on the top portion 620 of the trolley body 600. The support bracket 900 allows the vehicle body under test to be placed directly onto the battery mounting simulation assembly, further facilitating inspection of the mounting holes on the vehicle body under test.

[0080] Preferably, at least two of the support brackets 900 have adjustment devices 950. The adjustment devices 950 are used to roughly adjust the level of the vehicle body placed on the support brackets 900 when the battery installation simulation component is used for the first time or when there are significant changes in the vehicle body design, so as to prevent the vehicle body under test from tilting at a large angle relative to the battery installation simulation component.

[0081] By using the battery installation simulation unit 1000 according to this disclosure, users can efficiently and quickly check the positioning accuracy of multiple mounting holes, especially multiple non-threaded holes, for battery components on the vehicle body under test. Using the battery installation simulation unit 1000 according to this disclosure also allows users to conveniently transport the battery installation simulation unit 1000 to the testing location and eliminates the need for additional lifting or hoisting devices.
