Description

Technical Field

[0001] This application belongs to the field of junction box installation technology, and more specifically, relates to a junction box connection device and a vehicle. Background Technology

[0002] The cable guard box for the A-pillar splicing connector is used to house different terminals and accommodate various types of wire harnesses. The cable guard box needs to be fixed to the vehicle's sheet metal to prevent displacement or shaking of the wire harness connectors due to vehicle vibration, which could lead to poor contact at the connector ends.

[0003] In the existing technology, the cable protection box is usually directly fixed to the vehicle sheet metal by threaded connectors. However, the positioning point of the cable protection box is different on different vehicle models, and the type and shape of the connector connected to the cable protection box are also different. Therefore, it is necessary to adjust the position of the positioning hole or change the connection position of the cable protection box during the assembly process, which makes the assembly difficult, inefficient and costly. Utility Model Content

[0004] The purpose of this application is to provide a junction box connection device and vehicle, which aims to solve the technical problems of difficult assembly, low efficiency and high cost of existing junction boxes during assembly and connection.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a junction box connection device is provided, comprising: A connecting frame has a first side and a second side arranged opposite to each other; multiple sets of connecting structures are spaced apart on the first side, and multiple sets of limiting structures are spaced apart on the second side. The elastic positioning element has one end limited on one of the set of limiting structures, and the other end extends away from the connecting frame; Among them, at least one set of the connecting structures is engaged with the connector, and at least one set of the extended ends of the elastic positioning members are engaged within the body sheet metal.

[0006] The solution shown in this application embodiment, compared with the prior art, achieves the connection between the connector and the body sheet metal by setting a connecting frame between the connector and the body sheet metal; and multiple sets of connecting structures are provided on the first side of the connecting frame, which can adapt to the size and shape of connectors with various different structures, so as to ensure that at least one set of connecting structures can be adapted to the type of connector, thereby ensuring that the connecting frame can achieve an effective connection between the connecting frame and the connector. The elastic positioning component is used to connect the connecting frame and the body sheet metal. In this application, multiple sets of limiting structures are provided on the other side of the connecting frame, which can limit the elastic positioning component at different limiting structures to form different positions of the elastic positioning component, thereby matching the position of the elastic positioning component with the positioning position on the body sheet metal, and ensuring the effective connection between the connecting frame and the elastic positioning component. The cable guard box connection device provided in this application can adapt to the connection positions of different connectors and match the positioning positions of different body sheet metals. It has strong adaptability and good compatibility, which can effectively solve the problem of difficult connector assembly, reduce assembly costs and improve assembly efficiency.

[0007] In conjunction with the first aspect, in one possible implementation, the connecting frame extends in an L-shape, with the inner side of the L-shaped connecting frame being the first side and the outer side being the second side.

[0008] By setting the connector frame to an L-shape, it can accommodate connectors with right-angle structures and body panels, as well as connectors with straight-line structures and body panels, effectively improving the adaptability of the connector frame.

[0009] In conjunction with the first aspect, in one possible implementation, the connection structure includes: A fixed frame is fixed to the first side; A first connecting block is disposed within the fixed frame, and the first connecting block is provided with a first connecting hole suitable for the insertion of a connector; The length of the fixed frame is greater than that of the first connecting block, and the first connecting block is slidably connected within the fixed frame along its length.

[0010] The first connecting block can slide within the fixed frame. Therefore, the position of the first connecting block within the fixed frame can be adjusted, allowing the connection part of the connector to be finely adjusted as the first connecting block moves within the fixed frame. This adapts to the tolerance requirements of the part size and reduces the difficulty of connector assembly.

[0011] In some embodiments, the fixed frame is provided with a first sliding cavity extending along its length, and the first connecting block is provided with a slide bar adapted to extend into the first sliding cavity; wherein the slide bar is slidably connected within the first sliding cavity.

[0012] By sliding the slider in the first sliding cavity, the first connecting block can slide within the fixed frame, which is beneficial for fine-tuning the connector engagement.

[0013] For example, the connection structure further includes: The second connecting block is fixed on the connecting frame; the second connecting block is provided with a positioning connecting hole suitable for positioning the connector.

[0014] By setting a fixed second connecting block, the connector can be positioned at the positioning connecting hole of the connecting frame first, and then the connector can be snapped into the first connecting hole to increase the connection point, thereby reducing the difficulty of assembling the connector and the connecting structure as a whole.

[0015] In conjunction with the first aspect, in one possible implementation, the multiple sets of the aforementioned limiting structures specifically refer to: Multiple limiting blocks are spaced apart on the second side along the length direction of the connecting frame; Multiple first slide grooves are spaced apart along the length of the connecting frame on the second side; each first slide groove has a corresponding limiting block; the multiple first slide grooves are connected end to end to form a slide rail; Wherein, after one end of the elastic positioning member slides into one section of the first sliding groove, it is limited at the corresponding limiting block.

[0016] By setting the first slide groove, the elastic positioning component is initially limited in the length direction perpendicular to the connecting frame; and by setting a set of limiting blocks in the first slide groove, the elastic positioning component can be limited in the length direction of the connecting frame, thereby achieving effective limiting of the elastic positioning component; and by connecting multiple sections of the first slide groove into an integrated slide, it is convenient to process.

[0017] In some embodiments, a baffle is provided at one end of the slide; a limiting surface is provided on the side of the limiting block away from the baffle, and the limiting surface extends obliquely towards the baffle; the elastic positioning member is provided with a fitting surface that matches the inclination angle of the limiting surface; The elastic positioning member is used to slide in from the other end of the slide rail and enter the first slide groove of the corresponding segment after sliding past multiple limiting surfaces in sequence.

[0018] By setting an inclined and extended limiting surface, on the one hand, the elastic positioning component can be easily slid into the sliding surface, and on the other hand, the contact surface with the elastic positioning component can be easily limited, thereby limiting the elastic positioning component in the length direction of the connecting frame. The limiting block has a limiting surface on only one side, and a baffle is set at one end of the slide, with the limiting surface extending towards the baffle. Therefore, one end of the elastic positioning component can be slid into the limiting surface from one side, and the elastic positioning component is prevented from sliding out from the baffle side, thus achieving effective limiting of the elastic positioning component.

[0019] In conjunction with the first aspect, in one possible implementation, the elastic positioning member is provided with multiple levels of locking blocks at intervals in the direction away from the connecting frame, and the cross-sectional dimensions of the multiple levels of locking blocks gradually increase; wherein, the extension end of the elastic positioning member extends from one side of the body sheet metal, and one set of the locking blocks is engaged with the other side of the body sheet metal.

[0020] By setting up multiple levels of locking blocks with different cross-sectional dimensions, different levels of locking effects can be achieved. Furthermore, if one set of locking blocks is damaged or destroyed, other locking blocks can be used to lock the components, thus extending the service life of the elastic positioning components.

[0021] In some embodiments, the elastic positioning element includes: The sliding part is limited within the corresponding limiting structure; A support portion, fixedly connected to the sliding portion, and extending in a direction away from the connecting frame; and Two elastic plates are respectively disposed on both sides of the support portion; one end of the elastic plate is fixed to the extension end of the support portion, and the other end extends inclinedly away from the support portion. Each of the elastic card plates is provided with multiple levels of card blocks.

[0022] By setting a sliding part, it is possible to connect with the limiting structure on the connecting frame; by setting an elastic plate, it is convenient for the support part to drive the elastic plates on both sides to insert into the corresponding snap-fit ​​groove of the body sheet metal; and, the above-mentioned multiple clips can be conveniently set on the elastic plate.

[0023] Secondly, embodiments of this application also provide a vehicle that includes the aforementioned cable protection box connection device.

[0024] The vehicle provided in this application embodiment, having the aforementioned cable protection box connecting device, possesses all the beneficial effects of the aforementioned cable protection box connecting device. It can adapt to the connection positions of different cable protection boxes and match the positioning positions of different body sheet metals, exhibiting strong adaptability and good compatibility. It can effectively solve the problem of connector assembly difficulties, thereby reducing assembly costs and improving assembly efficiency. Attached Figure Description

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] It should be noted that the orientation or positional relationship indicated by "inner" and "outer" in this embodiment is based on the orientation of the connecting frame 1 itself. The inner side of the connecting frame 1 refers to the side of the connecting frame 1 that is closer to the connector, i.e., the first side 11. The outer side of the connecting frame 1 refers to the side of the connecting frame 1 that is away from the connector and closer to the body sheet metal, i.e., the second side 12.

[0032] Wherein, the extension direction of the connecting frame 1 is the same as the length direction of the connecting frame 1; the length in the length direction of the connecting frame 1 is relative to the width of the connecting frame 1, that is, the direction of the longer side on the same side is the length direction, and the direction of the shorter side on the same side is the width direction.

[0033] It is important to understand that in the existing technology, the cable protection box is directly connected to the body sheet metal. Since the shape and size of the body sheet metal of different models are different, as are the connection structures, the connector connection points on the body sheet metal are not exactly the same. When installing the connector, the connection structure on the connector needs to be adjusted according to the shape of the body sheet metal and the position of the connection points.

[0034] Moreover, the connection structure on the connector and the slot structure on the body sheet metal that connects to the cable protection box have certain tolerances. During the installation process, when the tolerances accumulate to a certain extent, there is a certain misalignment between the connection structure on the connector and the slot structure on the body sheet metal, which will increase the assembly difficulty of the connector.

[0035] Please refer to the following: Figures 1 to 7 The cable protection box connection device and vehicle provided in this application will now be described. The cable protection box connection device includes a connecting frame 1 and an elastic positioning member 4; the connecting frame 1 has a first side 11 and a second side 12 arranged opposite to each other; multiple sets of connecting structures 2 are spaced apart on the first side 11, and multiple sets of limiting structures 3 are spaced apart on the second side 12; the elastic positioning member 4 has one end limited on one set of limiting structures 3, and the other end extends away from the connecting frame 1; wherein, at least one set of connecting structures 2 is engaged with a connector, and the extended end of at least one set of elastic positioning members 4 is engaged in the body sheet metal.

[0036] It should be understood that this application makes improvements from two perspectives: the connector and the body sheet metal. On the one hand, the first side 11 of the connecting frame 1 is improved by setting multiple sets of connecting structures 2 on the first side 11, so that at least one set of connecting structures 2 can be adapted to the mounting point position on the connector, thereby ensuring the connection between the first side 11 and the connector. On the other hand, the second side 12 is improved by setting multiple sets of limiting structures 3 on the second side 12, and making the mounting point of at least one set of limiting structures 3 correspond to the mounting point position on the body sheet metal, thereby facilitating the installation of the elastic positioning member 4 at the corresponding position, and then snapping the elastic positioning member 4 onto the body sheet metal.

[0037] It should be understood that the connection between the connector 1 and the connector and the body sheet metal used in this application is a detachable connection, which can be easily installed and disassembled, and is beneficial for the disassembly, repair and inspection of the cable protection box.

[0038] Furthermore, compared to traditional stud-type positioning components, the elastic positioning component 4 in this application can be snapped into the corresponding body sheet metal, making connection convenient and effectively shortening assembly time and improving assembly efficiency. It should be noted that the elastic positioning component 4 has a certain degree of elasticity, allowing it to be easily snapped into the corresponding body sheet metal.

[0039] In addition, the body sheet metal in this application can specifically be the body sheet metal on the lower side of the left A-pillar, or the body sheet metal on the lower side of the right A-pillar, or the sheet metal structure of other parts of the body; the specific installation can be selectively performed according to actual needs.

[0040] It should be noted that the body sheet metal is provided with a snap-fit ​​groove for installing the elastic positioning member 4, which snaps into the end of the elastic positioning member 4 away from the connecting frame 1. At the same time, the connector is provided with a connecting part for adapting to the connecting structure 2, for snapping the connector into and limiting it within the corresponding connecting structure 2.

[0041] It should be noted that the multiple mounting points mentioned in this application do not mean that the connector and the connecting frame 1 can be installed in any position, nor can the installation position of the connector be continuously adjusted, nor is it applicable to all vehicle models. The beneficial effect of the cable guard box connecting device provided in this application is that, compared with the traditional technology, it can only be adapted to one type of vehicle model. That is, this application can meet the need for multiple mounting points between the connector and the connecting frame 1, and can meet the connector installation needs of various different vehicle models.

[0042] Similarly, the structure of the connecting frame 1 and the elastic positioning element 4 in this application can meet the needs of multiple installation points between the connecting frame 1 and the body sheet metal, thus adapting to various vehicle models, but not all vehicle models.

[0043] Compared with the prior art, the cable protection box connection device provided in this application realizes the connection between the connector and the body sheet metal by setting a connection frame 1 between the connector and the body sheet metal; and multiple sets of connection structures 2 are provided on the first side 11 of the connection frame 1, which can adapt to the size and shape of various connectors with different structures, so as to ensure that at least one set of connection structures 2 can be matched with the type of connector, thereby ensuring that the connection frame 1 can realize the effective connection between the connection frame 1 and the connector.

[0044] The elastic positioning element 4 is used to connect the connecting frame 1 and the body sheet metal. In this application, multiple sets of limiting structures 3 are provided on the other side of the connecting frame 1, which can limit the elastic positioning element 4 at different limiting structures 3 to form different positions of the elastic positioning element 4, thereby matching the position of the elastic positioning element 4 with the positioning position on the body sheet metal, thus ensuring the effective connection between the connecting frame 1 and the elastic positioning element 4.

[0045] It should be noted that "at least one" in this application can be understood as one or more sets, and the specific number can be selectively installed according to actual needs. Specifically, for connectors with simple structures, positioning and connection can be achieved by using one set of connecting structures 2 and one set of elastic positioning elements 4; for some connectors, multiple sets of connecting structures 2 and two elastic positioning elements 4 need to be set for connection. Therefore, the two elastic positioning elements 4 can be limited at multiple points by limiting structures 3 corresponding to different positions, thereby achieving multi-point connection between the connecting frame 1 and the sheet metal of different vehicle bodies.

[0046] Preferably, the spacing direction of the multiple sets of connecting structures 2 on the first side 11 is the same as the spacing direction of the multiple sets of limiting structures 3 on the second side 12, and both are along the length direction of the connecting frame 1. This can be understood as the multiple sets of connecting structures 2 being spaced apart along the length direction of the connecting frame 1 on the first side 11, and the multiple sets of limiting structures 3 being spaced apart along the length direction of the connecting frame 1 on the first side 11.

[0047] Optionally, the elastic positioning element 4 is provided in two sets for easy snap-fit; alternatively, the connection structure 2 is provided in multiple sets to enhance the connection stability of the cable protection box.

[0048] The cable guard box connection device provided in this application can adapt to the connection positions of different connectors and match the positioning positions of different body sheet metals. It has strong adaptability and good compatibility, which can effectively solve the problem of difficult connector assembly, reduce assembly costs and improve assembly efficiency.

[0049] Please see Figure 1 In some possible embodiments, the connecting frame 1 extends in an L-shape, with the inner side of the L-shaped connecting frame 1 being the first side 11 and the outer side being the second side 12.

[0050] By setting the connector 1 to an L-shape, it can adapt to connectors with right-angle structures and body sheet metal, as well as connectors with straight structures and body sheet metal, which can effectively improve the adaptability of the connector 1.

[0051] It should be understood that when the connecting frame 1 is extended in an L-shape, a right angle is formed between the two right-angled sides of the connecting frame 1. The inner side of the connecting frame 1 referred to in this application refers to the inner side where the right angle is located, and the outer side refers to the side opposite to the inner side.

[0052] When the connector or body sheet metal is a one-sided connection, one of the right-angled sides of the connector frame 1 can be selected as the connection body; when the connector or body sheet metal is a two-sided connection, both right-angled sides can be used as the connection body to enhance the stability of the connection.

[0053] It should be noted that when the connecting frame 1 is L-shaped, a first side 11 and a second side 12 are provided on both right-angled sides of the L-shaped connecting frame 1, and multiple sets of connecting structures 2 are provided on the first side 11, and multiple sets of limiting structures 3 are provided on the second side 12.

[0054] As another specific embodiment of the above-mentioned connector, the connector 1 is a straight structure with a first side 11 and a second side 12 facing away from each other. The extension direction of the connector 1 can be understood as the length direction of the connector 1.

[0055] As another specific embodiment of the above-mentioned connector, the connecting frame 1 is an angled structure with a preset bending angle. Similarly, when the connecting frame 1 is an angled structure, a first side 11 and a second side 12 are provided on both sides of the connecting frame 1. The first side 11 is provided with multiple sets of connecting structures 2, and the second side 12 is provided with multiple sets of limiting structures 3.

[0056] When the connecting frame 1 is a straight structure, the length direction and the extension direction of the connecting frame 1 can be understood as the length direction of the straight structure.

[0057] When the connecting frame 1 is an L-shaped structure, the connecting frame 1 has two right-angled sides, and the two right-angled sides are arranged perpendicular to each other; at this time, each right-angled side forms a set of the above-mentioned straight-line structure, that is, each right-angled side has a reverse length, and multiple sets of connecting structures 2 located on each right-angled side are spaced apart along the length direction of their respective right-angled sides, or in other words, multiple sets of connecting structures 2 located on each right-angled side are spaced apart along the extension direction of their respective right-angled sides; multiple sets of limiting structures 3 located on each right-angled side are spaced apart along the length direction of their respective right-angled sides, or in other words, multiple sets of limiting structures 3 located on each right-angled side are spaced apart along the extension direction of their respective right-angled sides.

[0058] When the connecting frame 1 is an angled structure, the connecting frame 1 has two angled sides. At this time, each angled side forms a set of the above-mentioned straight structure, that is, each angled side has a reverse length. Multiple sets of connecting structures 2 located on each angled side are spaced apart along the length direction of their respective angled sides, or in other words, multiple sets of connecting structures 2 located on each angled side are spaced apart along the extension direction of their respective angled sides; multiple sets of limiting structures 3 located on each angled side are spaced apart along the length direction of their respective angled sides, or in other words, multiple sets of limiting structures 3 located on each angled side are spaced apart along the extension direction of their respective angled sides.

[0059] Please see Figure 6 and Figure 7 In some possible embodiments, the connection structure 2 includes a fixed frame 21 and a first connecting block 22; the fixed frame 21 is fixed on the first side 11; the first connecting block 22 is disposed inside the fixed frame 21, and the first connecting block 22 is provided with a first connecting hole 221 suitable for the insertion of a connector; wherein, the length of the fixed frame 21 is greater than that of the first connecting block 22, and the first connecting block 22 is slidably connected to the fixed frame 21 along its length direction.

[0060] The first connecting block 22 can slide within the fixed frame 21. Therefore, the position of the first connecting block 22 in the fixed frame 21 can be adjusted, so that the connection part of the connector can be finely adjusted with the first connecting block 22 within the fixed frame 21, thereby adapting to the tolerance requirements of the part size and reducing the difficulty of connector assembly.

[0061] It is important to understand that the connecting parts on the connector are often designed with certain tolerance values ​​in terms of machining dimensions. When the connector and the connecting frame 1 are connected by multiple connecting structures 2, the connecting structure 2 installed first can often be installed smoothly, while the connecting structure 2 installed later often becomes difficult to assemble due to the accumulation of tolerances.

[0062] The first connecting block 22 in this application can slide within the fixed frame 21. Therefore, the first connecting block 22 can be slid to adapt to the corresponding mounting point on the connector's connecting part, thereby sequentially assembling multiple connecting structures 2 with the connector.

[0063] Optionally, on the two right-angled sides of the L-shaped connecting frame 1, two sets of fixing frames 21 are provided on the long side and one set of fixing frames 21 is provided on the short side, and a set of first connecting blocks 22 are provided in each fixing frame 21.

[0064] It should be noted that the first connecting block 22 needs to protrude from the fixing frame 21 in a direction away from the connecting frame 1, and the first connecting hole 221 on the first connecting block 22 is provided on the protruding part of the first connecting block 22 to avoid mutual interference between the fixing frame 21 and the connecting part of the connector.

[0065] For ease of understanding, please refer to the appendix to this application. Figure 7 It is clearly seen that sliding gaps are left on both sides of the first connecting block 22 and the fixed frame 21, so that the first connecting block 22 can slide within the fixed frame 21.

[0066] The first connecting block 22 is used to cooperate with the connecting part on the connector to realize the connection between the connector and the connecting frame 1. The first connecting block 22 and the connecting part form a male and female mating structure and are connected as one unit. It can be understood that the connecting part on the connector slides into the first connecting hole 221 and is snapped and fixed with the first connecting block 22. It should be noted that the specific structure of the connecting part on the connector and the connection principle between the connecting part on the connector and the first connecting block 22 are all existing technologies and will not be described in detail here.

[0067] Please see Figure 7 In some embodiments, the fixed frame 21 is provided with a first sliding cavity 211 extending along its length direction, and the first connecting block 22 is provided with a slide bar 222 adapted to extend into the first sliding cavity 211; wherein the slide bar 222 is slidably connected in the first sliding cavity 211.

[0068] By sliding the slider 222 within the first sliding cavity 211, the first connecting block 22 can slide within the fixed frame 21, which is beneficial for achieving fine-tuning of the connector engagement.

[0069] Specifically, the first sliding cavity 211 is disposed between the fixed frame 21 and the connecting frame 1; optionally, the first sliding cavity 211 is perpendicular to the first reverse through the fixed frame 21 to facilitate the assembly of the slide bar 222 in the first sliding cavity 211 and to facilitate the observation of the installation position of the slide bar 222 from the through side of the first sliding cavity 211.

[0070] It should be understood that since the slider 222 is slidably connected in the first sliding cavity 211, the first connecting block 22 is limited to the fixed frame 21 along with the slider 222, which can prevent the first connecting block 22 from detaching from the fixed frame 21.

[0071] Please see Figure 6 For example, the connection structure 2 further includes a second connection block 23; the second connection block 23 is fixed on the connection frame 1; the second connection block 23 is provided with a positioning connection hole 231 suitable for positioning the connector.

[0072] By setting a fixed second connecting block 23, the connector can be positioned at the positioning connecting hole 231 of the connecting frame 1 first, and then the connector can be snapped into the first connecting hole 221 to increase the connection point, thereby reducing the difficulty of assembling the connector and the connecting structure 2 as a whole.

[0073] Similarly, the second connecting block 23 needs to protrude in a direction away from the connecting frame 1, and the positioning connecting hole 231 on the second connecting block 23 is provided on the protruding part of the second connecting block 23 to avoid mutual interference between the connecting frame 1 and the connecting part of the connector.

[0074] Preferably, the first connecting hole 221 and the positioning connecting hole 231 are at the same height and size from the second side 12 of the connecting frame 1, which facilitates processing.

[0075] Please see Figure 1 and Figure 2 In some possible embodiments, the multiple sets of limiting structures 3 specifically consist of multiple limiting blocks 31 and multiple segments of first slide grooves 322; the multiple limiting blocks 31 are spaced apart on the second side 12 along the length direction of the connecting frame 1; the multiple segments of first slide grooves 322 are spaced apart on the second side 12 along the length direction of the connecting frame 1; each segment of first slide groove 322 is provided with a corresponding limiting block 31; the multiple segments of first slide grooves 322 are connected end to end to form a slide 32; wherein, after one end of the elastic positioning member 4 slides into one segment of the first slide groove 322, it is limited at the corresponding limiting block 31.

[0076] By setting the first slide groove 322, the elastic positioning member 4 is initially limited in the length direction perpendicular to the connecting frame 1; and by setting a set of limiting blocks 31 in the first slide groove 322, the elastic positioning member 4 can be limited in the length direction of the connecting frame 1, thereby achieving effective limiting of the elastic positioning member 4; and by connecting multiple sections of the first slide groove 322 into an integrated slide rail 32, it is convenient to process.

[0077] It should be understood that when the connecting frame 1 extends in an L-shaped structure, the connecting frame 1 forms two right-angled sides, and the multiple first sliding grooves 322 on each right-angled side are connected end to end to form a first sliding track 32; when the connecting frame 1 extends in a straight line structure, the first sliding grooves 322 are connected end to end to form a second sliding track 32.

[0078] Optionally, two sliding columns are provided on the second side 12 of the connecting frame 1, and the two sliding columns are spaced apart along the length direction perpendicular to the connecting frame 1, forming a first sliding groove 322 extending along the length direction of the connecting frame 1; the sliding part 41 of the elastic positioning member 4 is provided with two sliding holes suitable for the sliding columns to pass through. When the elastic positioning member 4 is slidably connected to the two sliding columns, the sliding columns pass through the sliding holes of the elastic positioning member 4.

[0079] It is important to understand that when each sliding column is divided into multiple segments, a groove can be formed between two opposite segments.

[0080] Optionally, two guide posts are provided on the second side 12 of the connecting frame 1, and the two guide posts are spaced apart along the length direction perpendicular to the connecting frame 1. The guide posts are L-shaped and arranged opposite each other to form a first groove 322 extending along the first direction. The sliding part 41 of the elastic positioning member 4 is adapted to the shape of the first groove 322 enclosed by the guide posts, and the sliding part 41 is correspondingly slidably connected in the L-shaped guide posts on both sides.

[0081] Please see Figure 1 , Figure 3 and Figure 5 In some embodiments, a baffle 321 is provided at one end of the slide 32; a limiting surface 311 is provided on the side of the limiting block 31 away from the baffle 321, and the limiting surface 311 extends obliquely toward the baffle 321; the elastic positioning member 4 is provided with a fitting surface 411 that matches the inclination angle of the limiting surface 311; wherein, the elastic positioning member 4 is used to slide in from the other end of the slide 32, and enter the first slide groove 322 of the corresponding section after sliding past multiple limiting surfaces 311 in sequence.

[0082] By setting an inclined and extended limiting surface 311, on the one hand, the elastic positioning member 4 can be easily slid into the sliding surface, and on the other hand, it can be easily limited by the contact surface 411 of the elastic positioning member 4, thereby limiting the elastic positioning member 4 in the length direction of the connecting frame 1. The limiting block 31 has a limiting surface 311 on only one side, and a baffle 321 is set at one end of the slide 32, and the limiting surface 311 extends towards the baffle 321. Therefore, the elastic positioning member 4 can be slid into the limiting surface 311 from one side, and the elastic positioning member 4 is prevented from sliding out from the baffle 321 side, thereby achieving effective limiting of the elastic positioning member 4.

[0083] It should be understood that the contact surface 411 on the elastic positioning member 4 first contacts the limiting surface 311 on the limiting block 31, and then, during the process of pushing the elastic positioning member 4 to slide, the contact surface 411 slides past the limiting surface 311, which can facilitate pushing the elastic positioning member 4.

[0084] Optionally, the side of the limiting block 31 near the baffle 321 is a plane perpendicular to the connecting frame 1, in order to prevent the elastic positioning member 4 from sliding out again.

[0085] It should be understood that the elastic positioning member 4 has a certain elasticity. Therefore, when the elastic positioning member 4 is pushed to slide, the elastic positioning member 4 can pass over the limiting block 31 from the limiting surface 311 of the limiting block 31 and reach the other side of the limiting block 31.

[0086] Before installing the elastic positioning component 4, the installation position of the elastic positioning component 4 needs to be determined, that is, the corresponding set of limiting structures 3 to be installed needs to be determined. Then, the elastic positioning component 4 is slid into the slide from the end away from the baffle 321 on the slide rail 32 until it reaches the pre-installed limiting structure 3.

[0087] Furthermore, a connecting rod is connected between the two guide posts or the two sliding posts, and the connecting rod is provided with the aforementioned contact surface 411.

[0088] Specifically, when the connecting frame 1 is L-shaped, a slide 32 is formed on each of the two right-angled sides of the connecting frame 1, and a set of baffles 321 is provided on each slide 32. Preferably, the two sets of baffles 321 are located at the ends of the two slides 32 that are far apart from each other. Specifically, the position of the baffles 321 can be selectively set according to actual needs.

[0089] Please see Figure 4 In some possible embodiments, in the direction away from the connecting frame 1, the elastic positioning member 4 is provided with multiple levels of locking blocks 431 at intervals, and the cross-sectional dimensions of the multiple levels of locking blocks 431 gradually increase; wherein, the extension end of the elastic positioning member 4 extends from one side of the body sheet metal, and one set of locking blocks 431 is engaged with the other side of the body sheet metal.

[0090] By setting up multiple levels of locking blocks 431 with different cross-sectional dimensions, on the one hand, different levels of locking effect can be achieved; on the other hand, when one set of locking blocks 431 is damaged or destroyed, other locking blocks 431 can be used for locking, which can extend the service life of the elastic positioning element 4.

[0091] It should be understood that the groove structure on the body sheet metal often has a certain tolerance value. Therefore, by designing multiple levels of different sizes of locking blocks 431, when the tolerance requirements are high, the locking block 431 with a relatively loose locking degree can be selected for locking, which can reduce the difficulty of locking.

[0092] Specifically, the slot structure on the body sheet metal is a snap-fit ​​hole, which is an elongated hole; preferably, the two ends of the elongated hole are rounded arc transition structures.

[0093] In addition, the elastic positioning component 4 can be detachably connected to the body sheet metal. During disassembly and use, the locking block 431 may become loose. After multiple disassembly and assembly, in order to ensure the tightness and stability of the connection between the elastic positioning component 4 and the body sheet metal, a larger locking block 431 can be replaced for locking to enhance the tightness of the connection between the elastic positioning component 4 and the body sheet metal.

[0094] Furthermore, the thickness of the body sheet metal varies, specifically between 0.8-3mm; the multi-level locking blocks 431 in this application are spaced apart along the extension direction of the elastic positioning member 4, so the multi-level locking blocks 431 can adapt to body sheet metal of different thicknesses.

[0095] For example, when the curvature of the body sheet metal is small, such as 1mm, the locking block 431 away from the extended end of the elastic positioning member 4 can be locked with the other side of the body sheet metal; conversely, when the curvature of the body sheet metal is large, such as 3mm, the locking block 431 near the extended end of the elastic positioning member 4 can be locked with the other side of the body sheet metal.

[0096] Please see Figure 4and Figure 5 In some embodiments, the elastic positioning member 4 includes a sliding part 41, a support part 42, and two elastic locking plates 43; the sliding part 41 is limited within the corresponding limiting structure 3; the support part 42 is fixedly connected to the sliding part 41 and extends away from the connecting frame 1; the two elastic locking plates 43 are correspondingly arranged on both sides of the support part 42; one end of the elastic locking plate 43 is fixed to the extended end of the support part 42, and the other end extends obliquely away from the support part 42; wherein, each elastic locking plate 43 is provided with multiple levels of locking blocks 431.

[0097] By providing a sliding part 41, it is possible to connect with the limiting structure 3 on the connecting frame 1; by providing an elastic plate 43, it is convenient for the support part 42 to drive the elastic plates 43 on both sides to be inserted into the corresponding snap-fit ​​groove of the body sheet metal; and, it is convenient to provide the above-mentioned multiple snap-fit ​​blocks 431 on the elastic plate 43.

[0098] Specifically, the sliding part 41 is slidably disposed in the corresponding first groove 322, and the sliding part 41 is provided with a fitting surface 411 that fits against the limiting surface 311 of the limiting block 31; by providing the sliding part 41, the limiting connection between the elastic positioning member 4 and the connecting frame 1 is realized.

[0099] The support part 42 is used to enhance the stability of the connection between the two sets of elastic snap-fit ​​plates and improve the support strength of the elastic positioning member 4; optionally, a reinforcing rib is added to the support part 42 near the sliding part 41 to improve the support stability of the support part 42.

[0100] Optionally, an annular cover plate is provided at the connection between the sliding part 41 and the support part 42. After the elastic positioning member 4 is engaged, it is placed on the groove of the body sheet metal to improve the aesthetics of the connection between the body sheet metal and the connecting bracket 1, while preventing dust and impurities from entering the groove of the body sheet metal and affecting the disassembly and assembly of the elastic positioning member 4.

[0101] Furthermore, multiple weight-reduction holes are provided on the connecting frame 1; the multiple weight-reduction holes are spaced apart along the length direction of the connecting frame 1.

[0102] Based on the same inventive concept, this application also provides a vehicle that includes the above-mentioned cable protection box connection device.

[0103] The vehicle provided in this application embodiment, having the aforementioned wire protection box connecting device, possesses all the beneficial effects of the aforementioned wire protection box connecting device. It can adapt to the connection positions of different wire protection boxes and match the positioning positions of different body sheet metals, exhibiting strong adaptability and good compatibility. It can effectively solve the problem of difficult wire protection box assembly, thereby reducing assembly costs and improving assembly efficiency.

[0104] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
