Description

Technical Field

[0001] The utility model generally relates to the technical field of connectors, and more particularly to a connection assembly for realizing floating connection. Background Art

[0002] A vehicle's subframe typically connects the vehicle body and suspension system. Currently, some vehicles have subframes rigidly bolted to the vehicle's underbody panels. When a vehicle travels over rough roads, the front and rear suspension systems experience movement and vibration. This movement and vibration is transmitted to the underbody panels through the rigid connection between the subframe and the underbody panels, subjecting them to significant dynamic loads and potentially causing fatigue damage. This is particularly detrimental for underbody panels made of, for example, plastic. Utility Model Content

[0027] The following describes the implementation and use of the embodiments in detail. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present invention and are not intended to limit the scope of the present invention. When describing the structural positions of components, such as up, down, top, bottom, left, and right, the references to these positions are not absolute but relative. These references are appropriate when the components are arranged as shown in the figures, but they will change accordingly if the positions of the components in the figures are changed.

[0028] The terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated. In this utility model, unless expressly provided otherwise, the terms "installed," "connected," "connected," and "fixed" should be interpreted broadly. For example, they may refer to fixed connections, removable connections, or integral connections; and they may be directly connected or indirectly connected through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0029] Figures 1 to 5C The connecting assembly 10 and its components according to an exemplary embodiment of the present invention are shown. The connecting assembly 10 can connect a first member 20 to a second member 30 and allow a certain relative movement between the first member 20 and the second member 30 to achieve a floating connection between the first member 20 and the second member 30.

[0030] Reference Figures 1 to 3 The connection assembly 10 includes a first connection member 100, a second connection member 200, and a shaft assembly 300. The first connection member 100 includes a base wall 102 adapted to be connected to the first member 20, and a first side wall 104 and a second side wall 106 extending from the base wall 102 and opposing each other. The second connection member 200 includes a base plate 202 opposing the base wall 102 and adapted to be connected to the second member 30, and a first side plate 204 and a second side plate 206 extending from the base plate 202 and opposing each other. The first connection member 100 is connected to the second connection member 200 via the shaft assembly 300, which includes a shaft 302. The first side wall 104 and the second side wall 106 include a first opening 108 and a second opening 110, respectively, and the first side plate 204 and the second side plate 206 include a first slot 208 and a second slot 210, respectively. The shaft 302 extends through the first opening 108, the second opening 110, the first slot 208, and the second slot 210. The shaft 302 is loosely fitted with the first opening 108 and the second opening 110 and the shaft 302 can move within the first slot 208 and the second slot 210 along the extension direction E of the first slot 208 and / or the second slot 210, so that the first connecting member 100 can move relative to the second connecting member 200 along the axial direction A of the shaft 302, and the first connecting member 100 can move relative to the second connecting member 200 along the extension direction E together with the shaft 302.

[0031] In this way, the connection assembly 10 can allow the first component 20 connected to the first connector 100 to move relative to the second component 30 connected to the second connector 200 along the aforementioned axial direction A and extension direction E. This can achieve a floating connection between the first component 20 and the second component 30, which is particularly advantageous in situations where the first component 20 itself may move relative to the second component 30. Compared to a rigid connection, the first connector 100 and the second connector 200 of the connection assembly 10 will move relative to each other when the first component 20 and the second component 30 move relative to each other, thereby preventing stress concentration or dynamic loads at the connection between the first component 20 and the second component 30 from causing damage.

[0032] Reference Figure 1 and Figure 2 , the first component 20 can be a vehicle subframe, and the second component 30 can be a vehicle chassis guard plate. The vehicle subframe connects the vehicle body and the suspension system. When the vehicle is traveling on a rough road, the front and rear suspensions will move and vibrate, causing the vehicle subframe to be displaced relative to the vehicle chassis guard plate. Connecting the vehicle subframe and the vehicle chassis guard plate through the connecting assembly 10 can allow the above-mentioned relative movement of the vehicle subframe and the vehicle chassis guard plate, thereby avoiding stress concentration or damage due to dynamic load at the connection between the vehicle subframe and the vehicle chassis guard plate. It can be understood that the application of the connecting assembly 10 according to the utility model is not limited to this, but can be applied to various scenarios where it is necessary to enable the connected first component 20 and the second component 30 to move relative to each other within a certain range.

[0033] Reference Figure 2 and Figure 3 In the illustrated embodiment, the connecting assembly 10 includes two shaft assemblies 300. The two shaft assemblies 300 can have the same structure. Accordingly, the first side wall 104 and the second side wall 106 of the first connecting member 100 respectively include two first openings 108 and two second openings 110. The first side plate 204 and the second side plate 206 of the second connecting member 200 respectively include a first slot 208 and a second slot 210. The shaft 302 of each shaft assembly 300 extends through a corresponding first opening 108, a corresponding second opening 110, the first slot 208, and the second slot 210. The first connecting member 100 is coupled to the second connecting member 200 via the two shaft assemblies 300 (this will be more easily understood in conjunction with the following description). In the illustrated embodiment, the first connecting member 100 can be supported on the shaft assemblies 300. The shaft assemblies 300 can be made of metal to provide a stable connection between the first connecting member 100 and the second connecting member 200 and provide better support for the first connecting member 100.

[0034] It is understandable that in other embodiments not shown, the connecting assembly may also include other suitable numbers of shaft assemblies, such as one shaft assembly or more than two shaft assemblies. Accordingly, the first connecting member may include other suitable numbers of first openings and second openings, and the second connecting member may include other suitable numbers of first slots and second slots.

[0035] Reference Figures 1 to 4A , the first connector 100 can be made of metal. Alternatively, the first connector 100 can be formed by stamping a metal plate. The base wall 102 of the first connector 100 can be roughly rectangular in shape and include two first protrusions 112 protruding toward the interior of the first connector 100, each first protrusion 112 having a first fastening hole 114. The two first fastening holes 114 can be passed through by two externally threaded fasteners to connect the base wall 102 of the first connector 100 to the first member 20. It will be understood that in other embodiments not shown, the base wall can also have other suitable shapes; the base wall can also include other suitable numbers of first protrusions with first fastening holes, for example, one first protrusion or more than two first protrusions.

[0036] The first side wall 104 and the second side wall 106 of the first connector 100 can be symmetrically arranged with respect to each other, for example, symmetrically arranged with respect to the axis of the first fastening hole 114. In the illustrated embodiment, the first side wall 104 and the second side wall 106 of the first connector 100 stand upright relative to the base wall 102 and form a substantially 90° angle with the base wall 102. The first side wall 104 and the second side wall 106 of the first connector 100 are disposed between the first side plate 204 and the second side plate 206 of the second connector 200, and the base wall 102 of the first connector 100 and the base plate 202 of the second connector 200 are substantially parallel to each other. It is understood that in other embodiments not shown, the first side plate and the second side plate of the second connector can be disposed between the first side wall and the second side wall of the first connector.

[0037] Reference Figures 2 to 4A In the illustrated embodiment, the first side wall 104 has a first step portion 116 (see Figure 4A ), so that: the portion of the first side wall 104 including the first opening 108 is recessed toward the interior of the first connector 100 relative to the portion of the first side wall 104 located between the first step portion 116 and the base wall 102. The second side wall 106 has a second step portion 118 (see Figure 4A), such that the portion of the second side wall 106 including the second opening 110 is recessed toward the interior of the first connector 100 relative to the portion of the second side wall 106 located between the second step 118 and the base wall 102. This prevents mechanical interference between the first connector 100 and the first and second sleeves 304, 306 of the shaft assembly 300 (the first and second sleeves 304, 306 will be described in detail below) when the first connector 100 moves relative to the second connector 200 along the shaft 302 of the shaft assembly 300. In the illustrated embodiment, reinforcing ribs 117 and 119 may also be provided at the first and second step 116, 118, respectively, to increase the rigidity of the first and second side walls 104, 106. It will be appreciated that the configurations of the first and second side walls are not limited thereto and may also have other suitable configurations.

[0038] In the illustrated embodiment, each first opening 108 in the first sidewall 104 and the corresponding second opening 110 in the second sidewall 106 are substantially aligned in the axial direction A of the shaft 302 of the corresponding shaft assembly 300. Each first opening 108 in the first sidewall 104 and the corresponding second opening 110 in the second sidewall 106 are clearance-fitted with the shaft 302 of the corresponding shaft assembly 300 to allow the first connector 100 to move relative to the second connector 200 along the shaft 302 and thereby move relative to the second connector 200 in the axial direction A. In other embodiments not shown, the shaft of the shaft assembly may further include a sheath made of a polymer material to reduce friction noise when the first connector moves relative to the second connector in the axial direction A.

[0039] Reference Figures 1 to 3 , the second connecting member 200 can be made of metal. Alternatively, the second connecting member 200 can be formed by stamping a metal plate. The base plate 202 of the second connecting member 200 can also be roughly rectangular in shape and include two second protrusions 212 protruding toward the interior of the second connecting member 200, each second protrusion 212 having a second fastening hole 214. The two second fastening holes 214 can be passed through by two externally threaded fasteners to connect the base plate 202 of the second connecting member 200 to the second component 30. It will be understood that in other embodiments not shown, the base plate may also have other suitable shapes; the base plate may also include other suitable numbers of second protrusions with second fastening holes, for example, one second protrusion or more than two second protrusions.

[0040] In the illustrated embodiment, the first side plate 204 and the second side plate 206 are symmetrically arranged relative to each other, for example, symmetrically arranged relative to the axis of the second fastening hole 214. The first side plate 204 and the second side plate 206 of the second connecting member 200 can be erected relative to the base plate 202 and form a substantially 90° angle with the base plate 202. In the illustrated embodiment, reinforcing ribs 203 and 205 can also be provided at the junction of the first side plate 204 and the base plate 202, and at the junction of the second side plate 206 and the base plate 202, respectively, to increase the rigidity of the second connecting member 200. It will be understood that the configuration of the first side plate and the second side plate is not limited to this, and other suitable configurations can also be provided.

[0041] In the illustrated embodiment, the axial direction A of the shaft 302 is substantially perpendicular to the first side wall 104, the second side wall 106, the first side plate 204, and the second side plate 206, and is substantially parallel to the base wall 102 and the base plate 202. The first slot 208 of the first side plate 204 and the second slot 210 of the second side plate 206 are substantially aligned in the axial direction A of the shaft 302 of the shaft assembly 300. The first slot 208 and the second slot 210 have the same shape and extending direction.

[0042] Reference Figure 24 , each of the two shaft assemblies 300 is mounted on and retained in the second connector 200, and the shaft 302 of each shaft assembly 300 passes through the first opening 108 and the second opening 110 of the first connector 100, thereby coupling the first connector 100 to the second connector 200 via the two shaft assemblies 300. Each shaft assembly 300 further includes a first shaft sleeve 304 and a second shaft sleeve 306 sleeved over the shaft 302. The first shaft sleeve 304 and the second shaft sleeve 306 are mounted in the first slot 208 and the second slot 210, respectively, and are movable along the first slot 208 and the second slot 210, respectively. Because the shaft 302 of each shaft assembly 300 is loosely fitted with the first opening 108 and the second opening 110 of the first connecting member 100, and the sleeves 304 and 306 of each shaft assembly 300 can move along the corresponding slots 208 and 210, the first connecting member 100 allows the shaft 302 and the sleeves 304 and 306 sleeved outside the shaft 302 to move relative to the second connecting member 200 along the extension direction E of the slots 208 and 210. In the illustrated embodiment, the axial direction A is substantially perpendicular to the extension direction E. In the illustrated embodiment, the first sleeve 304 includes a first annular groove 308 arranged on its outer circumference, and the second sleeve 306 includes a second annular groove 310 arranged on its outer circumference. The first annular groove 308 and the second annular groove 310 respectively engage the inner edge of the first slot 208 and the inner edge of the second slot 210, thereby guiding the first sleeve 304 and the second sleeve 306 to move along the first slot 208 and the second slot 210, respectively, and then guiding the shaft 302 to move along the first slot 208 and the second slot 210.

[0043] The first side plate 204 further includes a third slot 216 adjacent to and in communication with the first slot 208, and the second side plate 206 further includes a fourth slot 218 adjacent to and in communication with the second slot 210. The third slot 216 and the fourth slot 218 are configured to install the first and second sleeves 304, 306 into the first and second slots 208, 210, respectively, during assembly of the connection assembly 10.

[0044] The third slot 216 is sized to allow the first sleeve 304 to be installed in the third slot 216 along its axial direction, and the first slot 208 is sized to prevent the first sleeve 304 from being separated from the first slot 208 along its axial direction. The fourth slot 218 is sized to allow the second sleeve 306 to be installed in the fourth slot 218 along its axial direction, and the second slot 210 is sized to prevent the second sleeve 306 from being separated from the second slot 210 along its axial direction.

[0045] The maximum width of the third slot 216 (i.e., the maximum dimension of the third slot 216 in a direction perpendicular to its extension direction) can be greater than the maximum outer diameter of the first sleeve 304, and the maximum width of the first slot 208 (i.e., the maximum dimension of the first slot 216 in a direction perpendicular to the extension direction E) can be smaller than the maximum outer diameter of the first sleeve 304 and greater than the outer diameter of the first sleeve 304 at the first annular groove 308, so that the first sleeve 304 can first be installed in the third slot 216 and engage with the inner edge of the third slot 216, and then move along the inner edge of the third slot 216 into the first slot 208 and remain in the first slot 208. The maximum width of the fourth slot 218 (i.e., the maximum dimension of the fourth slot 218 in a direction perpendicular to its extension direction) can be greater than the maximum outer diameter of the second sleeve 306, and the maximum width of the second slot 210 (i.e., the maximum dimension of the second slot 210 in a direction perpendicular to the extension direction E) can be less than the maximum outer diameter of the second sleeve 306 and greater than the outer diameter of the second sleeve 306 at the second annular groove 310, so that the second sleeve 306 can first be installed in the fourth slot 218 and engage with the inner edge of the fourth slot 218, and then move along the inner edge of the fourth slot 218 into the second slot 210 and remain in the second slot 210.

[0046] After the connection assembly 10 is assembled, during the movement of the first connector 100 relative to the second connector 200 along the extension direction E, the first sleeve 304 remains located within the first slot 208 and the second sleeve 306 remains located within the second slot 210. This is achieved by the second retaining structure described below. Thus, during the movement of the first connector 100 relative to the second connector 200 along the extension direction E, the first sleeve 304 will not enter the third slot 216 and the second sleeve 306 will not enter the fourth slot 218, thereby accidentally falling off the second connector 200.

[0047] In the illustrated embodiment, the first slot 208 forms an obtuse angle with the third slot 216, and the second slot 210 forms an obtuse angle with the fourth slot 218. Compared to an arrangement in which the first slot and the third slot are collinear, and the second slot and the fourth slot are collinear, this arrangement allows the first side plate 204 and the second side plate 206 to have smaller dimensions, thereby reducing the volume of the second connector 200.

[0048] In the illustrated embodiment, the shaft 302 of each shaft assembly 300 includes a shaft body 312 and a cover portion 314 disposed at one end of the shaft body 312. The cover portion 314 can at least partially accommodate the first shaft sleeve 304 or the second shaft sleeve 306. Each shaft assembly 300 also includes a retaining ring 316 mounted at the other end of the shaft body 312. The cover portion 314 and the retaining ring 316 cooperate to limit axial movement of the shaft 302 relative to the first shaft sleeve 304 and the second shaft sleeve 306, thereby preventing the shaft 302 from being separated from the second connector 200.

[0049] By retaining the first and second sleeves 304 and 306 in the first and second slots 208 and 210 , respectively, and limiting axial movement of the shaft 302 relative to the first and second sleeves 304 and 306 , the shaft assembly 300 can be securely retained on the second connector 200 .

[0050] In the illustrated embodiment, the shafts 302 of the two shaft assemblies 300 are arranged in different orientations such that the cover portions 314 of the two shafts 302 are located on either side of the second connector 200, thereby preventing mechanical interference between the cover portions 314 of the two shafts 302. It will be appreciated that in other embodiments not shown, the shafts may not include cover portions, and instead two retaining rings may be provided at both ends of the shafts to limit axial movement of the shafts relative to the first and second sleeves.

[0051] Reference Figures 2 to 5C The connection assembly 10 includes a first limiting structure and a second limiting structure. The first limiting structure is configured to limit the range of motion of the first connection member 100 relative to the second connection member 200 in the axial direction A, so that the first connection member 100 is in a first limit position (such as Figure 4B As shown) and the second extreme position (as Figure 4C The second limiting structure is configured to limit the range of motion of the first connecting member 100 relative to the second connecting member 200 along the extension direction E, so that the first connecting member 100 is in the third limit position (as shown) relative to the second connecting member 200 in the extension direction E. Figure 5B As shown) and the fourth extreme position (as Figure 5C shown).

[0052] In the illustrated embodiment, the first limiting structure includes a second protrusion 212, which extends from the base plate 202 between the first side wall 104 and the second side wall 106 and can selectively abut against either the first side wall 104 or the second side wall 106 to limit the movement of the first connector 100 relative to the second connector 200 along the axial direction A. Figure 4BAs shown, the second protrusion 212 can abut against the second side wall 106, and the first side wall 104 can abut against the first side plate 204 to limit the first connecting member 100 from further moving leftward relative to the second connecting member 200 along the axial direction A. At this time, the first connecting member 100 is in a first limit position relative to the second connecting member 200; Figure 4C As shown, the second protrusion 212 can abut against the first side wall 104, and the second side wall 106 can abut against the second side plate 206 to limit the first connecting member 100 from further moving to the right along the axial direction A relative to the second connecting member 200. At this time, the first connecting member 100 is in the second extreme position relative to the second connecting member 200.

[0053] It is understood that the first limiting structure may have many variations. For example, in other embodiments not shown, where the first side plate and the second side plate of the second connector are disposed between the first side wall and the second side wall of the first connector, the first limiting structure may include a first protrusion extending from the base wall between the first side plate and the second side plate and capable of selectively abutting against either the first side plate or the second side plate to limit movement of the first connector relative to the second connector along the axial direction A.

[0054] Continue to refer to Figures 2 to 5C The second retaining structure includes a first retaining groove 120 and a second retaining groove 122 provided on the first connector 100, and a first retaining tab 220 and a second retaining tab 222 provided on the second connector 200. The first retaining groove 120 and the second retaining groove 122 are symmetrically arranged, for example, symmetrically arranged with respect to the axis of the first fastening hole 114. The first retaining groove 120 and the second retaining groove 122 may extend substantially parallel to the extension direction E of the first slot 208 and the second slot 210. The first retaining tab 220 and the second retaining tab 222 are symmetrically arranged, for example, symmetrically arranged with respect to the axis of the second fastening hole 214.

[0055] In the illustrated embodiment, the first limiting groove 120 and the second limiting groove 122 are respectively disposed at the junction of the first side wall 104 and the base wall 102, and at the junction of the second side wall 106 and the base wall 102. The first limiting tab 220 and the second limiting tab 222 extend toward each other from the first side panel 204 and the second side panel 206, respectively, and extend through the first limiting groove 120 and the second limiting groove 122, respectively.

[0056] The first limiting groove 120 has two opposing ends. The first limiting tab 220 can selectively abut against either end of the first limiting groove 120 to limit movement of the first connector 100 relative to the second connector 200 along the extension direction E. The second limiting groove 122 has two opposing ends. The second limiting tab 222 can selectively abut against either end of the second limiting groove 122 to limit movement of the first connector 100 relative to the second connector 200 along the extension direction E.

[0057] Reference Figure 3 as well as Figures 5A to 5C The first limiting protrusion 220 and the second limiting protrusion 222 can respectively abut the right end of the first limiting groove 120 and the right end of the second limiting groove 122 to limit the first connecting member 100 from moving further leftward relative to the second connecting member 200 along the extension direction E. At this time, Figure 5B As shown, the first connecting member 100 is in the third limit position relative to the second connecting member 200; the first limiting protrusion 220 and the second limiting protrusion 222 can respectively abut the left end of the first limiting groove 120 and the left end of the second limiting groove 122 to limit the first connecting member 100 from further moving rightward along the extension direction E relative to the second connecting member 200. At this time, as shown in FIG. Figure 5C As shown, the first connecting member 100 is in the fourth extreme position relative to the second connecting member 200. In addition, due to the provision of the second limiting structure, the range of motion of the first connecting member 100 relative to the second connecting member 200 along the extension direction E is limited, so that the first sleeve 304 is always located in the first slot 208 and the second sleeve 306 is always located in the second slot 210 as described above.

[0058] Optionally, the second limiting structure is configured such that: during the relative movement of the first connecting member 100 and the second connecting member 200, the first limiting protrusion 220 does not contact the upper and lower edges of the first limiting groove 120, and the second limiting protrusion 222 does not contact the upper and lower edges of the second limiting groove 122, so as to avoid noise caused by friction between the first limiting protrusion 220 and the first limiting groove 120 and friction between the second limiting protrusion 222 and the second limiting groove 122.

[0059] Optionally, the second retaining structure is configured such that: during relative movement between the first connector 100 and the second connector 200, each of the first retaining tab 220 and the second retaining tab 222 is spaced apart from the base wall 102 to prevent the first retaining tab 220 and the second retaining tab 222 from rubbing against the base wall 102 and generating noise. In the illustrated embodiment, the first retaining tab 220 forms an acute angle with the first side plate 204, and the second retaining tab 222 forms an acute angle with the second side plate 206 to ensure that each of the first retaining tab 220 and the second retaining tab 222 is spaced apart from the base wall 102 during relative movement between the first connector 100 and the second connector 200, thereby reducing friction and noise.

[0060] In the illustrated embodiment, reinforcing ribs 221 , 223 are further provided at the junction of the first limiting protrusion 220 and the first side plate 204 and at the junction of the second limiting protrusion 222 and the second side plate 206 to further enhance the rigidity of the second connecting member 200 .

[0061] It is understood that the second limiting structure can also have many variations. For example, in other embodiments not shown, the first limiting groove and the second limiting groove can also be respectively provided at the first side wall and the second side wall instead of being provided at the junction of the first side wall and the base wall and the junction of the second side wall and the base wall; for another example, in other embodiments not shown, when the first side plate and the second side plate are provided between the first side wall and the second side wall, the first limiting tab and the second limiting tab can respectively extend from the first side plate and the second side plate in a manner away from each other (i.e., extending away from each other); for another example, in other embodiments not shown, other suitable numbers of limiting tabs and limiting grooves can be provided, for example, one or more limiting grooves can be provided on the first connecting member, and one or more limiting tabs can be provided on the second connecting member accordingly; for another example, in other embodiments not shown, a limiting tab can be provided on the first connecting member, and a limiting groove can be provided on the second connecting member.
