Description

Technical Field

[0001] The present application belongs to the technical field of filter installation, and specifically relates to a filter support device for engineering vehicles. Background Art

[0002] The filter is a major component of the engine. It can filter the air entering the engine to reduce internal wear of the engine and ensure that sufficient and clean air enters the engine.

[0003] At present, for engineering vehicles, their filters are generally installed on the side of the frame and on the inner side of the wheel. As a result, during the driving of the engineering vehicle, the dust brought by the wheel will adhere to the filter, thereby affecting the service life of the filter. The wheel will also bring up particles, which will cause collisions with the filter, which may cause damage to the filter and also affect the service life of the filter. At the same time, existing engineering vehicles generally have two-stage filtration, which requires the configuration of two filters, and the installation space of the filter is relatively cramped, which in turn affects the installation efficiency of the filter. Utility Model Content

[0004] The present application provides a filter support device for engineering vehicles to extend the service life of the filter and improve the installation efficiency of the filter.

[0005] The technical solutions adopted in this application are:

[0006] A filter support device for an engineering vehicle includes a mounting bracket provided on a vehicle frame and a protective bracket detachably connected to the mounting bracket. The protective bracket is located on a side of the mounting bracket facing away from the vehicle frame, and an accommodating space for accommodating a filter is formed between the mounting bracket and the protective bracket. The mounting bracket has a first mounting position and a second mounting position for installing the filter.

[0007] By adopting the above technical solution, when installing the filter, the two filters are first installed at the first mounting position and the second mounting position provided on the mounting bracket respectively, and then the mounting bracket with the two filters installed is installed on the vehicle frame, and then the protective bracket is installed on the mounting bracket, so that the protective bracket protects the filter. Since the protective bracket is located on the side of the mounting bracket away from the vehicle frame, it avoids the dust raised by the engineering vehicle during driving from adhering to the filter or the particles colliding with the filter, thereby greatly improving the service life of the filter and reducing the maintenance frequency and use cost of the engineering vehicle; at the same time, since the two filters are integrated and installed on the mounting bracket in this application, it avoids the need to install the two filters in a limited space, thereby improving the installation efficiency of the filter and greatly reducing the difficulty of installing the filter.

[0008] Optionally, the protective bracket includes a bracket body detachably connected to the mounting bracket and a protective plate detachably connected to the outer side of the bracket body, and the bottom of the protective plate extends to the bottom of the filter.

[0009] By adopting the above technical solution, since the bottom of the protective plate extends to the bottom of the filter, the protective effect of the protective plate on the filter is increased, thereby further extending the service life of the filter, further reducing the use cost of the engineering vehicle, and ensuring the engine air intake of the engineering vehicle; and the protective plate is detachably connected to the bracket body, and then the protective plate can be removed when the filter element is replaced to achieve the effect of facilitating the replacement of the filter element, greatly improving the efficiency of replacing the filter element, and at the same time greatly reducing the difficulty of repair and maintenance of engineering vehicles.

[0010] Optionally, the protective plate is flexible so that it can be folded upward in a vertical direction.

[0011] By adopting the above technical solution, since the protective plate is flexible, the protective plate can be folded upward in the vertical direction, so that when replacing the filter element, it is only necessary to fold the protective plate upward, so as to further reduce the difficulty of replacing the filter element and further improve the efficiency of replacing the filter element. After the protective plate loses its upward folding force, the protective plate can naturally droop under the action of its own flexibility and gravity to protect the filter; in addition, the bottom end of the protective plate can bend toward the side where the frame is located under the action of its own flexibility to achieve bottom protection of the filter, thereby greatly improving the protection effect of the filter.

[0012] Optionally, the top of the bracket body has a connecting piece, and a fixing piece is provided on the outer side of the connecting piece. The protective plate is located between the connecting piece and the fixing piece, and the two are squeezed and fixed to the protective plate by a bolt pair.

[0013] By adopting the above technical solution, when replacing the protective plate, the bolt pair is removed, and then the fixing plate and the protective plate are removed, and then the new protective plate is installed on the inner side of the fixing plate. Finally, the bolts are used to fix the fixing plate again to complete the replacement of the protective plate. During this process, only the bolt pair needs to be disassembled, which greatly improves the replacement efficiency of the protective plate and can extend the service life of the filter support device.

[0014] Optionally, the bracket body has a supporting plate located below the connecting plate, and the supporting plate can support the protective plate.

[0015] By adopting the above technical solution, since the bracket body has a support plate located below the connecting plate, the support plate can support the protective plate to increase the stability of the protective plate and avoid the protective plate from sticking to the filter, thereby ensuring the protective effect of the protective plate on the filter; in addition, the support plate can also increase the structural strength of the bracket body to ensure the protective effect of the protective bracket on the filter.

[0016] Optionally, the support plate is provided with at least one fixing hole, and the fixing hole is used to install a fixing member for fixing the wiring harness.

[0017] By adopting the above technical solution, since the support plate is provided with a fixing hole, the fixing parts required to fix the wiring harness can be installed in the fixing hole, so as to increase the stability of the wiring harness, avoid the mutual friction between the wiring harness and the filter, and thus increase the service life of the wiring harness; at the same time, the wiring harness and the filter avoid each other, so as to achieve the effect of facilitating the replacement of the filter element.

[0018] Optionally, the bracket body has limiting pieces located on both sides of the protective plate, and the limiting pieces can contact the protective plate to support the protective plate.

[0019] By adopting the above technical solution, since the bracket body has limiting plates located on both sides of the protective plate, the limiting plates can support both sides of the protective plate to increase the stability of the protective plate and avoid the situation where the protective plate conflicts with the filter due to its own flexibility, thereby increasing the protective effect of the protective plate on the filter.

[0020] Optionally, the limiting plate includes a reinforcing section and a limiting section for supporting the protective plate, and the reinforcing section and the limiting section are arranged at an angle.

[0021] By adopting the above technical solution, since the reinforcing section and the limiting section are arranged at an angle, the reinforcing section can increase the structural strength of the limiting plate, thereby increasing the structural strength of the bracket body, thereby ensuring the supporting effect of the limiting section on the protective plate.

[0022] Optionally, the limiting piece is provided with a blocking portion, and a limiting space for the protective plate to pass through is formed between the blocking portion and the limiting piece.

[0023] By adopting the above technical solution, a limiting space for the protective plate to pass through is formed between the blocking part and the limiting plate, so that the blocking part can limit the protective plate to prevent the protective plate from folding in the direction away from the frame, thereby increasing the stability of the protective plate and avoiding the situation where the protective plate may contact the wheel, thereby greatly improving the protective effect of the protective plate on the filter.

[0024] Optionally, the mounting bracket includes a mounting plate and connecting parts provided on both sides of the mounting plate, and fixing parts are provided on both sides of the protective bracket. The fixing parts correspond to the connecting parts one by one and the two are detachably connected.

[0025] By adopting the above technical solution, when installing the protective bracket, first align the fixing part and the connecting part, and then apply force to the protective bracket in the direction close to the mounting bracket, so that the fixing part and the connecting part are in conflict and the two are connected together to complete the installation of the protective bracket; since the fixing part is arranged on both sides of the protective bracket and the connecting part is arranged on both sides of the mounting plate, the connection points between the protective bracket and the mounting bracket are increased, thereby increasing the connection stability between the protective bracket and the mounting bracket.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0027] 1. The filter support device of the present application includes a mounting bracket provided on a vehicle frame and a protective bracket detachably connected to the mounting bracket. The protective bracket is located on a side of the mounting bracket facing away from the vehicle frame, and a accommodating space for accommodating the filter is formed between the mounting bracket and the protective bracket. The mounting bracket has a first mounting position and a second mounting position for mounting the filter. When installing the filter, the two filters are first mounted on the first mounting position and the second mounting position provided on the mounting bracket, respectively. Then, the mounting bracket with the two filters mounted thereon is mounted on the vehicle frame. Then, the protective bracket is mounted on the mounting bracket so that the protective bracket protects the filters. Since the protective bracket is located on the side of the mounting bracket facing away from the vehicle frame, dust raised by the engineering vehicle during driving is prevented from adhering to the filters or particles from colliding with the filters, thereby greatly improving the service life of the filters and reducing the maintenance frequency and usage cost of the engineering vehicle. At the same time, since the two filters are integrated into the mounting bracket in the present application, the need to install the two filters in a limited space is avoided, thereby improving the installation efficiency of the filters and greatly reducing the difficulty of filter installation.

[0028] 2. The protective bracket in the present application includes a bracket body detachably connected to the mounting bracket and a protective plate detachably connected to the outside of the bracket body. The bottom of the protective plate extends to the bottom of the filter, thereby increasing the protective effect of the protective plate on the filter, so as to further extend the service life of the filter, further reduce the use cost of the engineering vehicle, and ensure the engine air intake of the engineering vehicle; and the protective plate is detachably connected to the bracket body, and then the protective plate can be removed when the filter element is replaced, so as to achieve the effect of facilitating the replacement of the filter element of the filter, greatly improving the efficiency of replacing the filter element of the filter, and at the same time greatly reducing the difficulty of repair and maintenance of the engineering vehicle.

[0029] 3. The protective plate in the present application is flexible, so that the protective plate can be folded upward in the vertical direction, so that when the filter element is replaced, it is only necessary to fold the protective plate upward, so as to further reduce the difficulty of replacing the filter element, so as to further improve the replacement efficiency of the filter element, and after the protective plate loses the upward folding force, the protective plate can naturally droop under the action of its own flexibility and gravity to protect the filter; in addition, the bottom end of the protective plate can bend toward the side where the frame is located under the action of its own flexibility to achieve bottom protection of the filter, thereby greatly improving the protection effect of the filter.

[0041] Reference Figures 1 to 3 , discloses a filter support device for an engineering vehicle, which includes a mounting bracket 1 provided on a vehicle frame and a protective bracket 2 detachably connected to the mounting bracket 1, the protective bracket 2 is located on a side of the mounting bracket 1 away from the vehicle frame, and an accommodating space for accommodating the filter is formed between the mounting bracket 1 and the protective bracket 2, the mounting bracket 1 has a first mounting position 111 and a second mounting position 112 for installing the filter.

[0042] When installing the filter, first install the two filters on the first mounting position 111 and the second mounting position 112 provided on the mounting bracket 1 respectively, and then install the mounting bracket 1 with the two filters installed on the vehicle frame, and then install the protective bracket 2 on the mounting bracket 1, so that the protective bracket 2 protects the filter. Since the protective bracket 2 is located on the side of the mounting bracket 1 away from the vehicle frame, it avoids the dust raised by the engineering vehicle during driving from adhering to the filter or the particles colliding with the filter, thereby greatly improving the service life of the filter and reducing the maintenance frequency and use cost of the engineering vehicle; at the same time, since the two filters are integrated and installed on the mounting bracket 1 in this application, it avoids the need to install the two filters in a limited space, thereby improving the installation efficiency of the filter and greatly reducing the difficulty of installing the filter.

[0043] The present application does not specifically limit the connection method between the mounting bracket 1 and the vehicle frame. Preferably, the mounting bracket 1 is connected to the vehicle frame by bolts to facilitate the installation of the mounting bracket 1. In other embodiments, the mounting bracket 1 can also be fixed to the vehicle frame by riveting, welding, etc.

[0044] This application does not make any specific limitation on the structure of the protective bracket 2. Preferably, refer to Figure 2 The protective bracket 2 includes a bracket body 21 detachably connected to the mounting bracket 1 and a protective plate 22 detachably connected to the outside of the bracket body 21. The bottom of the protective plate 22 extends to the bottom of the filter, thereby increasing the protective effect of the protective plate 22 on the filter, so as to further extend the service life of the filter, further reduce the use cost of the engineering vehicle, and ensure the engine air intake of the engineering vehicle; and the protective plate 22 is detachably connected to the bracket body 21, and then the protective plate 22 can be removed when the filter element is replaced, so as to achieve the effect of facilitating the replacement of the filter element of the filter, greatly improving the efficiency of replacing the filter element of the filter, and greatly reducing the difficulty of maintenance of the engineering vehicle.

[0045] It should be noted that the outer side of the bracket body 21 refers to the side of the bracket body 21 facing away from the mounting bracket 1 .

[0046] The present application does not specifically limit the structure of the protective plate 22. Preferably, the protective plate 22 is flexible so that the protective plate 22 can be folded upward in the vertical direction.

[0047] It can be understood that the protective plate 22 is a structure made of rubber or other flexible materials, so that when replacing the filter element, it is only necessary to fold the protective plate 22 upwards, so as to further reduce the difficulty of replacing the filter element and further improve the efficiency of replacing the filter element. After the protective plate 22 loses its upward folding force, the protective plate 22 can naturally droop under the action of its own flexibility and gravity to protect the filter; in addition, the bottom end of the protective plate 22 can bend toward the side where the frame is located under the action of its own flexibility to achieve bottom protection of the filter, thereby greatly improving the protection effect of the filter.

[0048] In other embodiments, the protective plate 22 may also be a hard plate-shaped structure made of metal material or hard plastic material.

[0049] The present application does not make any specific limitation on the detachable connection method between the protective plate 22 and the bracket body 21. Preferably, refer to Figure 2 and Figure 3 The top of the bracket body 21 has a connecting piece 211, and a fixing piece 215 is provided on the outside of the connecting piece 211. The protective plate 22 is located between the connecting piece 211 and the fixing piece 215, and the two are squeezed and fixed to the protective plate 22 by a bolt pair.

[0050] When replacing the protective plate 22, remove the bolt pair, then remove the fixing plate 215 and the protective plate 22, and then install the new protective plate 22 on the inner side of the fixing plate 215. Finally, the bolts are used to fix the fixing plate 215 again to complete the replacement of the protective plate 22. In this process, only the bolt pair needs to be disassembled, which greatly improves the replacement efficiency of the protective plate 22 and can extend the service life of the filter support device.

[0051] It should be noted that the outer side of the connecting piece 211 refers to the side of the connecting piece 211 facing away from the mounting bracket 1 , that is, the side of the connecting piece 211 facing away from the vehicle frame.

[0052] In other embodiments, the protective plate 22 may also be detachably connected to the bracket body 21 via a snap-fit ​​structure or a hanging structure.

[0053] In a preferred embodiment, referring to Figure 3 The bracket body 21 has a support piece 212 located below the connecting piece 211. The support piece 212 can support the protective plate 22 to increase the stability of the protective plate 22 and avoid the protective plate 22 from sticking to the filter, thereby ensuring the protective effect of the protective plate 22 on the filter; in addition, the support piece 212 can also increase the structural strength of the bracket body 21 to ensure the protective effect of the protective bracket 2 on the filter.

[0054] Further, refer to Figure 3 The support plate 212 is provided with at least one fixing hole 216, and the fixing hole 216 is used to install a fixing part for fixing the wiring harness.

[0055] Since the support plate 212 is provided with a fixing hole 216, the fixing parts required for fixing the wiring harness can be installed in the fixing hole 216 to increase the stability of the wiring harness, avoid the mutual friction between the wiring harness and the filter, and thus increase the service life of the wiring harness; at the same time, the wiring harness and the filter avoid each other, so as to achieve the effect of facilitating the replacement of the filter element.

[0056] Preferably, a plurality of fixing holes 216 are provided along the length direction of the support plate 212 to increase the fixing points of the wire harness, thereby increasing the stability of the wire harness.

[0057] In a preferred embodiment, referring to Figure 3 The bracket body 21 has a limiting piece 213 located on both sides of the protective plate 22. The limiting piece 213 can contact the protective plate 22 to support the protective plate 22, so as to increase the stability of the protective plate 22 and avoid the situation where the protective plate 22 contacts the filter due to its own flexibility, so as to increase the protective effect of the protective plate 22 on the filter.

[0058] Furthermore, the limiting piece 213 includes a reinforcing section and a limiting section for supporting the protective plate 22 , and the reinforcing section and the limiting section are arranged at an angle.

[0059] It is understandable that the cross-sectional shape of the limiting piece 213 is L-shaped, thereby increasing the structural strength of the limiting piece 213 to increase the structural strength of the bracket body 21 , thereby ensuring the supporting effect of the limiting section on the protective plate 22 .

[0060] Better, refer to Figure 3 The support piece 212 is C-shaped, and the two ends of the support piece 212 are respectively connected to the two reinforcing sections to increase the stability of the limiting piece 213, further increase the structural strength of the bracket body 21, and ensure the supporting effect of the bracket body 21 on the protective plate 22.

[0061] Further, refer to Figure 2 and Figure 3 The limiting plate 213 is provided with a blocking portion 217, and a limiting space for the protective plate 22 to pass through is formed between the blocking portion 217 and the limiting plate 213, so that the blocking portion 217 can limit the protective plate 22 to prevent the protective plate 22 from folding in the direction away from the frame, thereby increasing the stability of the protective plate 22 and avoiding the situation where the protective plate 22 may contact the wheel, thereby greatly improving the protection effect of the protective plate 22 on the filter.

[0062] The present application does not specifically limit the structure of the blocking portion 217. Preferably, the blocking portion 217 is an L-shaped sheet structure, with one end of the blocking portion 217 fixedly connected to the reinforcing section, and the other end of the blocking portion 217 disposed parallel to the limiting section with a gap between the blocking portion 217 and the limiting section for the protective plate 22 to pass through. In other embodiments, the blocking portion 217 may also be a block-shaped structure disposed on the limiting piece 213, as long as a gap is formed between the blocking portion 217 and the limiting piece 213 for the protective plate 22 to pass through.

[0063] In other embodiments, the protective bracket 2 may also be an integrated structure, such as a C-shaped plate structure, etc.

[0064] The present application does not make any specific limitation on the detachable connection method between the protective bracket 2 and the mounting bracket 1. Preferably, refer to Figure 2 and Figure 3 The mounting bracket 1 includes a mounting plate 11 and connecting portions 12 provided on both sides of the mounting plate 11. A fixing portion 214 is provided on both sides of the protective bracket 2. The fixing portion 214 corresponds to the connecting portion 12 one by one and the two are detachably connected.

[0065] When installing the protective bracket 2, first align the fixing portion 214 with the connecting portion 12, and then apply force to the protective bracket 2 in the direction close to the mounting bracket 1, so that the fixing portion 214 and the connecting portion 12 are in conflict and the two are connected together to complete the installation of the protective bracket 2; since the fixing portion 214 is provided on both sides of the protective bracket 2 and the connecting portion 12 is provided on both sides of the mounting plate 11, the connection points between the protective bracket 2 and the mounting bracket 1 are increased, thereby increasing the connection stability between the protective bracket 2 and the mounting bracket 1.

[0066] Specifically, the first installation position 111 and the second installation position 112 are both provided on the installation plate 11 .

[0067] Preferably, the fixing portion 214 is located outside the connecting portion 12 , that is, the two fixing portions 214 are respectively located on the sides of the two connecting portions 12 facing away from each other, so as to facilitate the installation of the protective bracket 2 on the mounting bracket 1 .

[0068] The present application does not specifically limit the structure of the connecting portion 12 and the fixing portion 214. Preferably, refer to Figure 2 and Figure 3 The connecting portion 12 and the fixing portion 214 are both sheet-like structures to reduce the weight of the filter support device and reduce the production cost of the filter support device. In other embodiments, the connecting portion 12 and the fixing portion 214 can also be block-like structures.

[0069] The present application does not specifically limit the manner in which the fixing portion 214 and the connecting portion 12 are detachably connected. Preferably, the fixing portion 214 and the connecting portion 12 are detachably connected via a bolt pair to ensure the stability of the connection between the protective bracket 2 and the mounting bracket 1.
