Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically, to a limiting mechanism for the front of the cab and a vehicle. Background Technology

[0002] As automotive exterior styling continues to evolve, the size and weight of the front bulkhead assembly are gradually increasing. To ensure the stability of the front bulkhead assembly during the closing process and its durability under complex driving conditions, the design and performance of the limiting components, which serve as both connecting and limiting parts, are particularly important.

[0003] Currently, most limiting components are unidirectional limiting designs, using black EPDM rubber material. Vibration reduction and buffering are achieved by adjusting the Shore D hardness. This unidirectional limiting block can ensure the stability of the front bulkhead outer panel in a certain direction. However, when the vehicle is driving on uneven roads, the multidirectional vibration between the front bulkhead outer panel, the fairing outer panel, and the fairing inner panel may exceed the buffering range of the unidirectional limiting block. In other words, the unidirectional limiting block cannot buffer multidirectional vibration, making it difficult to control the gap surface difference between these components, posing a risk of structural damage and affecting the overall service life of the cab.

[0004] There is currently no effective solution to the technical problem that unidirectional limiting blocks in existing technologies cannot buffer multidirectional vibrations. Utility Model Content

[0005] The main purpose of this utility model is to provide a limiting mechanism and vehicle for the front of the cab, so as to solve the technical problem that the unidirectional limiting block in the prior art cannot buffer multi-directional vibration.

[0006] To achieve the above objectives, according to one aspect of the present invention, a limiting mechanism for the front bulkhead of a driver's cab is provided, comprising: a mounting portion for connecting to an outer panel of a fairing; a first elastic portion, a first end of which is connected to the mounting portion, and a second end of which is disposed opposite to the outer panel of the front bulkhead to form a first gap between the first elastic portion and the outer panel of the front bulkhead; and a second elastic portion, a first end of which is connected to the mounting portion, and a second end of which is disposed opposite to an inner panel of the fairing to form a second gap between the second elastic portion and the inner panel of the fairing.

[0007] Furthermore, the mounting section, the first elastic section, and the second elastic section are integrally molded.

[0008] Furthermore, the mounting part is a columnar structure adapted to the mounting holes on the outer plate of the fairing. The radial dimension of the first end of the first elastic part is greater than the radial dimension of the mounting part, and the radial dimension of the first end of the second elastic part is greater than the radial dimension of the mounting part, so that a clamping space for clamping the outer plate of the fairing is formed between the first elastic part and the second elastic part.

[0009] Furthermore, the first end of the first elastic part is provided with a first limiting surface, which is used to abut against the outer plate of the fairing.

[0010] Furthermore, the first end of the first elastic part is also provided with a clearance structure, which is located inside the first limiting surface, and a clearance space is formed between the clearance structure and the extension surface of the first limiting surface.

[0011] Furthermore, the avoidance structure is an inclined surface, one end of which is connected to the outer peripheral surface of the mounting part, and the other end of which is connected to the first limiting surface.

[0012] Furthermore, the first end of the second elastic part is provided with a barb portion, which extends outward along the circumference of the second elastic part. The barb portion has a second limiting surface and a conical surface. The second limiting surface is used to abut against the outer plate of the guide shield, and the conical surface is gradually inclined inward in the direction away from the mounting part.

[0013] Furthermore, the edges of the first elastic portion and / or the second elastic portion are provided with rounded corners.

[0014] Furthermore, the first elastic part and / or the second elastic part are hollow structures.

[0015] According to another aspect of the present invention, a vehicle is provided, the vehicle including a limiting mechanism, the limiting mechanism being the aforementioned limiting mechanism.

[0016] Applying the technical solution of this utility model, the mounting part is connected between the first elastic part and the second elastic part. The second end of the first elastic part is positioned opposite to the outer front panel, and the first elastic part limits the deformation of the outer front panel while absorbing its vibration and deformation. The second end of the second elastic part is positioned opposite to the inner fairing panel, and the second elastic part absorbs the vibration and deformation of the inner fairing panel while limiting its deformation. The aforementioned limiting mechanism achieves bidirectional limiting and bidirectional vibration reduction through the first and second elastic parts. Attached Figure Description

[0036] Combination Figures 1 to 3 As shown in the specific embodiment of this application, a limiting mechanism for the front bulkhead of a driver's cab is provided.

[0037] Specifically, the limiting mechanism includes: a mounting part 1, a first elastic part 2, and a second elastic part 3. The mounting part 1 is used to connect with the outer panel 6 of the fairing. The first end of the first elastic part 2 is connected to the mounting part 1, and the second end of the first elastic part 2 is used to be disposed opposite to the outer panel 7 of the front cover, so that a first gap is formed between the first elastic part 2 and the outer panel 7 of the front cover. The first end of the second elastic part 3 is connected to the mounting part 1, and the second end of the second elastic part 3 is used to be disposed opposite to the inner panel 8 of the fairing, so that a second gap is formed between the second elastic part 3 and the inner panel 8 of the fairing.

[0038] In the embodiments of this application, the mounting part 1 is connected between the first elastic part 2 and the second elastic part 3. The second end of the first elastic part 2 is disposed opposite to the outer front panel 7, and the first elastic part 2 limits the deformation of the outer front panel 7 while absorbing the vibration and deformation of the outer front panel 7. The second end of the second elastic part 3 is disposed opposite to the inner diffuser panel 8, and the second elastic part 3 absorbs the vibration and deformation of the inner diffuser panel 8 while limiting the deformation of the inner diffuser panel 8. The above-mentioned limiting mechanism achieves bidirectional limiting and bidirectional vibration reduction through the first elastic part 2 and the second elastic part 3.

[0039] It should be further explained that a first gap is formed between the first elastic part 2 and the outer front panel 7, and a second gap is formed between the second elastic part 3 and the inner shroud panel 8. The gaps are designed to allow the first elastic part 2 and the second elastic part 3 to deform within a certain range, while preventing collisions with the elastic parts under slight vibrations, thus reducing noise and component wear.

[0040] In one exemplary embodiment of this application, the mounting portion 1, the first elastic portion 2, and the second elastic portion 3 are integrally formed. This integrally formed structure eliminates seams and connection points between separate components. When subjected to external impacts or vibrations, the integrally formed elastic portion can more effectively disperse stress, reduce the risk of breakage, and improve overall reliability and durability.

[0041] Preferably, the limiting mechanism in the embodiments of this application is integrally injection molded from rubber material.

[0042] In one exemplary embodiment of this application, the mounting part 1 is a columnar structure adapted to the mounting holes on the outer plate 6 of the flow guide. The radial dimension of the first end of the first elastic part 2 is greater than the radial dimension of the mounting part 1, and the radial dimension of the first end of the second elastic part 3 is greater than the radial dimension of the mounting part 1, so that a clamping space 5 for clamping the outer plate 6 of the flow guide is formed between the first elastic part 2 and the second elastic part 3.

[0043] The installation is limited by using the two end faces of the first elastic part 2 and the second elastic part 3 to install and limit the outer plate 6 of the flow guide, thereby simplifying the structure of the installation part 1 and eliminating the need for other external limiting structures; in addition, the first elastic part 2 and the second elastic part 3 are respectively connected to the outer plate 6 of the flow guide, which can absorb the deformation and vibration of the outer plate of the flow guide.

[0044] like Figure 1 , Figure 2 As shown, the first elastic part 2 has a conical structure. The draft angle of this conical structure can be adaptively adjusted according to actual needs. The radial dimension of this conical structure is larger than the radial dimension of the mounting part 1. A flange 23 is provided at one end of the first elastic part 2 near the mounting part 1. The flange 23 extends along the outer peripheral surface of the first elastic part 2 and is used to abut against the outer plate 6 of the flow guide. The second elastic part 3 has a columnar structure. The radial dimension of the second elastic part 3 near the mounting part 1 is larger than the radial dimension of the mounting part 1, so as to abut against the outer plate 6 of the flow guide.

[0045] As an alternative embodiment, the first elastic part 2 can be designed as a columnar structure or other three-dimensional structure, as long as it can limit and dampen the front outer panel 7.

[0046] Furthermore, the first end of the first elastic part 2 is provided with a first limiting surface 21, which is used to abut against the outer plate 6 of the fairing. By limiting and abutting against the surface, the fit between the mounting part 1 and the outer plate 6 of the fairing is made more stable.

[0047] Furthermore, the first end of the first elastic part 2 is also provided with a clearance structure 22, which is located inside the first limiting surface 21, and a clearance space 24 is formed between the clearance structure 22 and the extension surface of the first limiting surface 21.

[0048] When the mounting part 1 is inserted into the mounting hole on the outer plate 6 of the fairing, the setting of the avoidance structure 22 makes it easier for the end of the first elastic part 2 near the mounting part 1 to deform, thereby reducing the insertion resistance of the mounting part 1 and making the fit between the mounting part 1 and the outer plate 6 of the fairing smoother.

[0049] Preferred, the avoidance structure 22 is an inclined surface, one end of which is connected to the outer peripheral surface of the mounting part 1, and the other end of which is connected to the first limiting surface 21.

[0050] like Figure 3 As shown, the first limiting surface 21 is disposed on the outer end face of the flange 23, that is, the first limiting surface 21 is an annular surface. The clearance structure 22 is an inclined surface disposed on the inner end face of the flange 23, that is, the clearance structure 22 is a conical surface, and a conical clearance space 24 is formed between the extended surfaces of the first limiting surface 21 of the clearance structure 22. The provision of the clearance structure 22 helps to increase the elastic performance of the flange 23.

[0051] Furthermore, such as Figure 3 As shown, the first end of the second elastic part 3 is provided with a barb part 31. The barb part 31 extends outward along the circumference of the second elastic part 3. The barb part 31 has a second limiting surface and a conical surface. The second limiting surface is used to abut against the outer plate 6 of the flow guide. The conical surface is gradually inclined inward in the direction away from the mounting part 1.

[0052] When the mounting part 1 is inserted into the mounting hole on the outer plate 6 of the fairing, the barb 31 is easily deformed under the action of external force so that the barb 31 can pass through the mounting hole. After the barb 31 passes through the mounting hole, it returns to its original state so as to abut and limit the outer plate 6 of the fairing.

[0053] Furthermore, the edges of the first elastic part 2 and / or the second elastic part 3 are provided with rounded corner structures 32. The rounded corner structures 32 are provided to reduce the probability of collision with the elastic part under slight vibration, thereby reducing noise and component wear.

[0054] like Figure 3 As shown, the edge of the second elastic part 3 away from the mounting part 1 is provided with a rounded corner structure 32, which reduces the probability of contact between the inner plate of the flow guide 6 and the edge of the second elastic part 3 when the outer plate of the flow guide 6 or the inner plate of the flow guide 8 is deformed or vibrates.

[0055] In one exemplary embodiment of this application, the first elastic part 2 and / or the second elastic part 3 are hollow structures. The hollow structure can improve the elastic performance of the elastic parts and reduce the overall weight of the limiting mechanism.

[0056] like Figure 3 As shown, the limiting mechanism is provided with a weight reduction hole 4, which passes through the first elastic part 2, the mounting part 1 and part of the second elastic part 3 along the axial direction. The weight reduction hole 4 makes the first elastic part 2, the second elastic part 3 and the mounting part 1 all have a hollow structure.

[0057] According to another specific embodiment of this application, a vehicle is provided, the vehicle including a limiting mechanism, the limiting mechanism being the limiting mechanism in the above embodiment.

[0058] Specifically, the limiting mechanism includes a mounting part 1, a first elastic part 2, and a second elastic part 3. The mounting part 1 is connected to the outer panel 6 of the fairing. The first end of the first elastic part 2 is connected to the mounting part 1, and the second end of the first elastic part 2 is positioned opposite to the outer panel 7 of the front bulkhead, forming a first gap between them. The first elastic part 2 limits the deformation of the outer panel 7 while absorbing its vibration and deformation. The first end of the second elastic part 3 is connected to the mounting part 1, and the second end of the second elastic part 3 is positioned opposite to the inner panel 8 of the fairing, forming a second gap between them. The second elastic part 3 absorbs the deformation of the inner panel 8 of the fairing while also absorbing its vibration and deformation. The limiting mechanism achieves bidirectional limiting and bidirectional vibration reduction through the first elastic part 2 and the second elastic part 3, thereby reducing vibration during vehicle operation or collisions and making the vehicle run more smoothly.

[0059] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0060] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.
