Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, specifically to a locking assembly and a vehicle. Background Technology

[0002] Currently, most vehicle tailgates use traditional metal latches, with a rigid connection between the tailgate and the vehicle body formed by the tailgate lock engaging with the latch. Since this rigid connection cannot reduce vibrations transmitted from the chassis, when the tailgate mode coincides with the overall vehicle mode, vibration excitation occurs, resulting in low-frequency pressure ear problems, which seriously affect the user's driving and riding experience. Utility Model Content

[0003] In view of this, this application provides a latch assembly that can effectively avoid the problem of low-frequency ear pressure, thereby improving the user's driving experience. In addition, this application also provides a vehicle including the aforementioned latch assembly.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A locking assembly adapted for bolt connection to the body of a vehicle, comprising:

[0006] A connecting plate having mounting holes for connecting the vehicle body;

[0007] The first bushing includes a first flange and a first sleeve, wherein the first flange is disposed at one axial end of the outer peripheral surface of the first sleeve;

[0008] The second bushing includes a second flange and a second sleeve, wherein the second flange is disposed at one axial end of the outer peripheral surface of the second sleeve;

[0009] The buffer includes a first buffer portion located between the connecting plate and the first flange, and a second buffer portion located between the connecting plate and the second flange;

[0010] Wherein, the first flange and the second flange are located on opposite sides of the connecting plate, the first sleeve and / or the second sleeve are located in the mounting hole, and the other axial end of the first sleeve abuts against the other axial end of the second sleeve.

[0011] Optionally, the buffer further includes a third buffer portion located on the outer periphery of the second buffer portion and connected to the second buffer portion, and the third buffer portion protruding from the end face of the second flange away from the first flange.

[0012] Optionally, the buffer further includes a fourth buffer portion located within the mounting hole and on the outer periphery of the first sleeve and / or the second sleeve, and connected to the first buffer portion and the second buffer portion.

[0013] Optionally, the other axial end of the first sleeve has a stepped portion, the stepped portion including a first stepped surface, a second stepped surface and a third stepped surface, the first stepped surface and the third stepped surface extending radially, and the second stepped surface connecting the first stepped surface and the second stepped surface;

[0014] The first stepped surface abuts against the end of the second sleeve, and the third stepped surface abuts against the second flange.

[0015] Optionally, the second stepped surface surrounds the outer periphery of the second sleeve, and the first sleeve is interference-fitted with the second sleeve at the second stepped surface.

[0016] Optionally, the interference fit between the first sleeve and the second sleeve is 10 μm to 20 μm; and / or

[0017] The axial length of the second sleeve extending into the first sleeve is greater than or equal to 2 mm.

[0018] Optionally, the buffer element is attached to and connected as a whole with the surfaces of the first bushing, the second bushing, and the connecting plate.

[0019] Optionally, the first sleeve passes through the mounting hole and abuts against the second sleeve outside the mounting hole.

[0020] Optionally, the buffer element is a rubber component.

[0021] A vehicle comprising:

[0022] Body, including sheet metal parts with sheet metal holes;

[0023] The latch assembly is any one of the latch assemblies described above;

[0024] The locking assembly is connected to the sheet metal part by bolts passing through the mounting hole and the sheet metal hole, and the outer peripheral edge of the second flange in the orthographic projection of the sheet metal part is located on the outer periphery of the sheet metal hole.

[0025] The latch assembly provided in this application has a first buffer portion located between the connecting plate and the first flange, and a second buffer portion located between the connecting plate and the second flange. The latch assembly is installed at the rear of the vehicle body, and the buffer can serve as a vibration isolation structure between the floor and the vehicle body. Since the door lock (e.g., the tailgate lock) is directly connected to the latch assembly's locking pin in the latched state (i.e., the door lock is connected to the latch assembly), meaning the door lock is connected to the floor in the latched state, the buffer allows for a soft connection between the door and the vehicle body. This reduces vibration excitation when the door mode coincides with the vehicle's mode, solving the low-frequency pressure ear problem. Simultaneously, this design also avoids the lock popping phenomenon that occurs when the door is opened due to the large sealing reaction force provided by the sealing strip.

[0026] Furthermore, since the locking assembly abuts the other axial end of the first sleeve against the other axial end of the second sleeve, it can prevent the other axial end of the first sleeve from being suspended in the air after the locking assembly is installed on the vehicle body. This prevents the first bushing from axially displacing relative to the second bushing during the process of tightening the bolt to the nut, thereby preventing the buffer from being compressed and ensuring the buffer effect of the buffer.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] like Figure 1 and Figure 2 As shown, the latch assembly in this embodiment is adapted to be bolted to the vehicle body, and includes a connecting plate 2, a locking pin 1, a first bushing 4, a second bushing 5, and a buffer member 3.

[0036] in:

[0037] The connecting plate 2 is the base plate of the latch assembly, used to support other structural components of the latch assembly, and to connect the latch assembly to the vehicle body.

[0038] like Figure 1 As shown, in an exemplary embodiment, the connecting plate 2 can be configured as a plate-shaped structural component, specifically a sheet metal part. The connecting plate 2 has mounting holes for connecting to the vehicle body, facilitating the connection between the latch assembly and the vehicle body.

[0039] Locking pin 1 is a rigid component in the latch assembly that directly participates in the locking function. It engages and disengages with the lock's bolt and other structures.

[0040] like Figure 1 As shown, in an exemplary embodiment, the locking pin 1 can be a U-shaped structure formed by bending round steel or the like; and the open end of the locking pin 1 with the U-shaped structure is riveted and fixed to the connecting plate 2.

[0041] The first bushing 4 includes a first flange 401 and a first sleeve 402. The first sleeve 402 is the main body of the first bushing 4 and is a hollow columnar structure. The first flange 401 is an outwardly extending (i.e., extending away from the axis of the first bushing 4) flange structure, which is disposed at one axial end of the outer peripheral surface of the first sleeve 402.

[0042] The second bushing 5 includes a second flange 501 and a second sleeve 502, wherein the second sleeve 502 is the main body of the second bushing 5 and is a hollow columnar structure. The second flange 501 is an outwardly extending (i.e., extending away from the axis of the second bushing 5) flange structure, which is disposed at one axial end of the outer peripheral surface of the second sleeve 502.

[0043] Buffer component 3 is a functional component in the locking assembly used to reduce vibration transmission, such as... Figure 1As shown, the buffer 3 in this embodiment includes a first buffer portion 301 and a second buffer portion 302, wherein the first buffer portion 301 is located between the connecting plate 2 and the first flange 401, and the second buffer portion 302 is located between the second flange 501 and the connecting plate 2.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment of the application, the first flange 401 and the second flange 501 are located on opposite sides of the connecting plate 2, the first sleeve 402 and / or the second sleeve 502 are located in the mounting hole, and the other axial end of the first sleeve 402 abuts against the other axial end of the second sleeve 502.

[0045] After the aforementioned latch assembly is assembled onto the vehicle body, under the action of bolts, one end face of the first flange 401 or one end face of the second flange 501 abuts against the mounting surface of the vehicle body. For ease of description, the latch assembly in this embodiment will be described in more detail below, taking the abutment of one end face of the second flange 501 against the mounting surface of the vehicle body as an example.

[0046] Since the first buffer portion 301 of the buffer component 3 is located between the connecting plate 2 and the first flange 401, and the second buffer portion 302 is located between the connecting plate 2 and the second flange 501; the latch assembly is installed at the rear of the vehicle body, and the buffer component 3 can serve as a vibration isolation structure between the floor and the vehicle body; since the door lock (e.g., the rear door lock) is directly connected to the locking pin 1 of the latch assembly in the latched state (i.e., the door lock is connected to the latch assembly), that is, the door lock is connected to the floor in the latched state, the buffer component 3 allows a soft connection between the door and the vehicle body, thereby reducing the vibration excitation when the door mode coincides with the vehicle mode, and solving the low-frequency pressure ear problem. At the same time, this setting can also avoid the lock popping phenomenon when the door is opened due to the large sealing reaction force provided by the sealing strip.

[0047] Furthermore, as mentioned above, the locking assembly in this embodiment is connected to the vehicle body by bolts. Specifically, in some feasible implementations, sheet metal holes can be provided on the sheet metal parts of the vehicle body. During assembly, the bolts can be controlled to pass through the inner hole of the first bushing 4, the inner hole of the second bushing 5, and the sheet metal hole of the vehicle body before connecting with the nut, thereby fixing the locking assembly to the vehicle body.

[0048] Furthermore, to avoid machining and assembly errors that could prevent the door lock from connecting to the latch assembly after it is assembled on the vehicle body, the sheet metal hole can be designed with a larger diameter to allow for some adjustment in the radial direction (the radial direction refers to the direction perpendicular to the axial direction of the sheet metal hole) after the bolt passes through it.

[0049] The aforementioned sheet metal hole design results in the hole diameter being larger than the inner diameter of the first bushing 4 and the inner diameter of the second bushing 5; at this time, the projection of the first sleeve 402 in the axial direction will fall entirely or mostly within the sheet metal hole.

[0050] Based on the above, in the embodiment of this application, the locking assembly abuts the other axial end of the first sleeve 402 against the other axial end of the second sleeve 502, which can prevent the other axial end of the first sleeve 402 from being suspended after the locking assembly is assembled on the vehicle body. This prevents the first bushing 4 from axially displacing relative to the second bushing 5 during the process of tightening the bolt to the nut, thereby preventing the buffer 3 from being compressed and ensuring the buffering effect of the buffer 3.

[0051] Furthermore, during the above process, the axial force of the bolt acting on the first bushing 4 can be transmitted to the vehicle body through the second bushing 5. The above arrangement of this embodiment ensures that different structural components are in surface contact in the direction of force transmission, thereby making the stress distribution uniform. This avoids the second bushing 5 from deforming due to stress concentration during the process of tightening the bolt to the nut, further ensuring that the buffer 3 will not experience undesirable compression during the assembly of the locking assembly (undesirable compression refers to compression outside the design, or compression that may affect the buffering effect of the buffer 3), thereby ensuring the buffering effect of the buffer 3.

[0052] As mentioned earlier, the connecting plate 2 has mounting holes for connecting to the vehicle body. In specific implementation, the number of mounting holes can be adaptively designed according to needs.

[0053] In an exemplary implementation, such as Figure 1 As shown, in the length direction of the connecting plate 2, the locking pin 1 is connected to the middle position of the connecting plate 2. The connecting plate 2 has two mounting holes, and the two mounting holes are symmetrically arranged about the connection position of the locking pin 1.

[0054] Furthermore, as mentioned above, the first flange 401 and the second flange 501 are located on opposite sides of the connecting plate 2. In an optional embodiment, the projections of the first flange 401 and the second flange 501 in the axial direction of the mounting hole overlap. This arrangement is beneficial for optimizing the axial force of the locking assembly.

[0055] Of course, in specific implementation, the first flange 401 and the second flange 501 can also be arranged to alternately in the circumferential direction of the mounting hole.

[0056] like Figure 2 As shown, the buffer 3 in this application also includes a third buffer portion 303, which is disposed on the outer periphery of the second buffer portion 302, and the third buffer portion 303 protrudes from the end face of the second flange 501 away from the first flange 401.

[0057] Under the above configuration, when the latch assembly is assembled onto the vehicle body, the fourth buffer part 304 contacts the vehicle body first and deforms preferentially. This helps to distribute the pressure on the buffer part 3 during the assembly process to a larger area, thereby avoiding stress concentration, reducing local fatigue and abnormal noise, and reducing noise.

[0058] In addition, the buffer 3 contacts the vehicle body first, which will also affect the stiffness characteristics of the structure. It can provide lower stiffness in the initial stage, absorb more vibration energy, and isolate low-frequency vibrations; while the stiffness increases when the deformation is larger, preventing excessive displacement and reducing the transmission of high-frequency vibrations. Nonlinear stiffness can provide better damping characteristics and consume more vibration energy.

[0059] Continue as Figure 2 As shown, the buffer 3 also includes a fourth buffer portion 304, which is located inside the mounting hole and on the outer periphery of the first sleeve 402 and / or the second sleeve 502, and is connected to the first buffer portion 301 and the second buffer portion 302.

[0060] The fourth buffer portion 304 connects the first buffer portion 301 and the second buffer portion 302, making the buffer member 3 a single integral piece. With this configuration, when the buffer member 3 is deformed under stress, the various parts can support each other and work together to effectively absorb and disperse external impacts. Furthermore, the aforementioned configuration of the buffer member 3 can reduce the probability of displacement under external impacts, thereby improving the overall stability of the buffer member 3.

[0061] like Figure 2 As shown, the other axial end of the first sleeve 402 has a stepped portion, which includes a first stepped surface 4021, a second stepped surface 4022, and a third stepped surface 4023. The first stepped surface 4021 and the third stepped surface 4023 extend radially, and the second stepped surface 4022 connects the first stepped surface 4021 and the second stepped surface 4023. The first stepped surface 4021 abuts against the end of the second sleeve 502, and the third stepped surface 4023 abuts against the second flange 501. This arrangement helps to optimize the distribution of axial force between the first bushing 4 and the second bushing 5, further reducing the probability of stress concentration.

[0062] Furthermore, continuing as Figure 2 As shown, the second step surface 4022 surrounds the outer periphery of the second sleeve 502, and the first sleeve 402 is interference-fitted with the second sleeve 502 at the second step surface 4022.

[0063] This configuration allows for the connection of the first bushing 4 and the second bushing 5. On the other hand, the outer periphery of the second sleeve 502 can radially limit the first bushing 4, thereby improving the assembly accuracy of the first bushing 4 and the second bushing 5.

[0064] As described above, based on the interference fit between the first bushing 4 and the second bushing 5, the interference between the first sleeve 402 and the second sleeve 502 is 10μm to 20μm; and / or the axial length of the second sleeve 502 extending into the first sleeve 402 is greater than or equal to 2mm. This improves the reliability of the connection between the first bushing 4 and the second bushing 5.

[0065] Preferably, the interference fit between the first sleeve 402 and the second sleeve 502 is 10μm to 20μm, and the axial length of the second sleeve 502 extending into the first sleeve 402 is greater than or equal to 2mm.

[0066] It should be noted that the above example only illustrates one way of connecting the first bushing 4 and the second bushing 5 using an interference fit, but this application is not limited to this. For example, in specific implementations, the first bushing 4 and the second bushing 5 can also be connected by a threaded structure.

[0067] Furthermore, in a preferred embodiment, the buffer 3 is attached to and connected as a single unit with the surfaces of the first sleeve 402, the second sleeve 502, and the connecting plate 2. That is, in this embodiment, the connecting plate 2, the first bushing 4, and the second bushing 5 are connected as a single unit by the buffer 3. This arrangement improves the overall integrity of the locking assembly, preventing stress concentration caused by relative displacement between different components during use; thus, it helps to extend the service life of the locking assembly.

[0068] In practical implementation, the connecting plate 2, the first bushing 4 and the second bushing 5 can be placed in the mold, and then the material used to form the buffer 3 can be poured into the inner cavity of the mold. After the material used to form the buffer 3 solidifies, the buffer 3 can be attached to and connected to the surfaces of the first sleeve 402, the second sleeve 502 and the connecting plate 2 as one unit.

[0069] In some preferred embodiments, the first sleeve 402 passes through the mounting hole and abuts against the second sleeve 502 outside the mounting hole. This arrangement facilitates the positioning and connection of the first bushing 4 and the second bushing 5, thereby improving the assembly efficiency of the locking assembly.

[0070] Of course, in some other embodiments, the second sleeve 502 may be provided to pass through the mounting hole and abut against the first sleeve 402 outside the mounting hole; or the other axial end of the first sleeve 402 and the other axial end of the second sleeve 502 may both be located inside the mounting hole, and the other axial end of the first sleeve 402 and the other axial end of the second sleeve 502 abut against each other inside the mounting hole.

[0071] In addition, in some embodiments, the buffer 3 is a rubber component, specifically an EPDM rubber component.

[0072] In a further preferred embodiment, the hardness of the buffer 3 is approximately 40 HSA. This ensures that the rubber-coated buffer 3 can deform significantly without being subjected to excessive pressure, allowing it to absorb more force or vibration; thereby improving the buffering effect of the locking assembly.

[0073] Furthermore, this application also provides a vehicle, which includes a body and a latch assembly, wherein the latch assembly is the latch assembly of any of the above embodiments. It should be noted that since the vehicle includes the latch assembly in the above embodiments, the beneficial effects brought by the latch assembly to the vehicle are detailed above, and will not be repeated here.

[0074] In an exemplary embodiment, the vehicle body includes a sheet metal part with sheet metal holes, the latch assembly is connected to the sheet metal part by bolts passing through the mounting holes and the sheet metal holes, and the outer peripheral edge of the second flange 501 in the orthographic projection of the sheet metal part is located on the outer periphery of the sheet metal part.
