[0001] The utility model belongs to the technical field of manifolds for hydrogen fuel cells, and in particular relates to a distribution manifold and a vehicle. Background Art

[0002] Fuel cells generally use hydrogen as fuel as the negative electrode and oxygen in the air as the positive electrode. The manifold as the air intake pipe is currently mostly set as an integrated structure, especially some distribution manifolds, which integrate multiple pipes.

However, when fixing the distribution manifold to a vehicle, a set screw is generally used to pass through the distribution manifold to fix it to the vehicle. However, since the material of the distribution manifold is plastic, the distribution manifold can be easily crushed during the process of fastening the set screw to the vehicle, resulting in material loss.

DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figure 1-Figure 4 As shown, a distribution manifold comprises:

[0029] A first housing 100 and a second housing 101 are fixed to each other, the first housing 100 is provided with a first mounting portion, the second housing 101 is provided with a second mounting portion, the first mounting portion is provided with a plurality of first connecting through holes 104, and the second mounting portion is provided with a plurality of second connecting through holes 105 corresponding to the positions of the first connecting through holes 104 and having an equal number;

[0030] A plurality of pressure limiting members are provided on each of which a pressure limiting through hole 103 for accommodating the manifold fixing member is formed. Two ends of the pressure limiting member extend into the corresponding first connecting through hole 104 and the second connecting through hole 105 respectively.

[0031] When the distribution manifold is fixed on the vehicle, the manifold fixing member passes through the pressure limiting through hole 103 to be connected with the vehicle.

[0032] In this embodiment, in order to prevent the application of the fastening force of the manifold fixing part when the manifold fixing part fixes the manifold to the vehicle, which may cause the mounting part on the plastic distribution manifold to collapse, a pressure limiting part is added in the connecting through hole of the mounting part, and the two ends of the pressure limiting part are flush with the outer end surfaces of the corresponding first connecting through hole 104 and the second connecting through hole 105, respectively. Then, when the manifold fixing part applies a large force to the distribution manifold, the pressure limiting part distributes the force applied to the manifold fixing part to ensure that the force on the distribution manifold does not exceed its crushing force, so that the distribution manifold will not be damaged. In addition, when the manifold fixing part fixes the distribution manifold, the force applied by the manifold fixing part to the distribution manifold can also increase the stability of the connection between the first shell 100 and the second shell 101.

[0033] It is worth mentioning that the manifold fixings generally use connecting screws or connecting screws, which are passed through the connecting through holes on the distribution manifold and then screwed and fixed to the vehicle; and the material of the pressure limiting part is metal.

[0034] Specifically, the pressure limiting component includes a pressure limiting tube 102, a pressure limiting through hole 103 is opened in the pressure limiting tube 102, and the axis of the pressure limiting through hole 103 is parallel to the length direction of the pressure limiting tube 102, and the two ends of the pressure limiting tube 102 are respectively flush with the outer end surfaces of the corresponding first connecting through hole 104 and the second connecting through hole 105.

[0035] In this embodiment, the axis of the pressure limiting through hole 103 opened in the pressure limiting tube 102 is parallel to the length direction of the pressure limiting tube 102. Then, when the pressure limiting through hole 103 is installed in the distribution manifold, the axial direction of the pressure limiting through hole 103 is the same as the axial direction of the connecting through hole. When fixing the manifold, the screw head of the connecting screw abuts against the first mounting portion, and the second mounting portion abuts against the vehicle. Then, the two ends of the pressure limiting tube 102 are flush with the outer end surfaces of the corresponding first connecting through hole 104 and the second connecting through hole 105, respectively, so that the two ends of the pressure limiting tube 102 can also abut against the screw head and the vehicle. Then, the pressure limiting tube 102 can share the fastening force between the screw head and the vehicle, so that the force on the manifold does not exceed its limit crushing force.

[0036] In this embodiment, the first mounting portion includes a first mounting plate 106 arranged on the outer peripheral surface of the first shell 100, and the first connecting through hole 104 is opened on the first mounting plate 106; the second mounting portion includes a second mounting plate 107 arranged on the outer peripheral surface of the second shell 101, and the second connecting through hole 105 is opened on the second mounting plate 107, and when the first shell 100 and the second shell 101 are fixed, a gap is set between the first mounting plate 106 and the second mounting plate 107.

[0037] In this embodiment, the first shell 100 and the second shell 101 are both made of plastic, so when they are fixed, fusion welding is generally used. In order to ensure a stable connection between the first shell 100 and the second shell 101 during fusion welding, the first mounting plate 106 and the second mounting plate 107 cannot be offset against each other, thereby limiting the proximity of the first shell 100 and the second shell 101 during welding.

[0038] It is worth mentioning that the first connecting through hole 104 and the second connecting through hole 105 are both provided with guiding surfaces on their walls.

[0039] Preferably, the first shell 100 includes a pipe portion 108, and reinforcing ribs 109 are provided on both sides of the pipe portion 108. An extension column 110 is provided on the first mounting portion to fix the reinforcing ribs 109. An extension through hole is provided in the extension column 110. The extension through hole is concentrically arranged with a portion of the first connecting through hole 104, and one end of the pressure limiting part extends into the extension through hole and is flush with the outer end surface of the extension through hole.

[0040] In this embodiment, a pipeline portion 108 is provided on the first shell 100, that is, the pipeline in the distribution manifold is opened on the first shell 100, and the second shell 101 encapsulates the pipeline wall in the first shell 100 to form a complete pipeline. In order to ensure the strength of the pipeline portion 108, reinforcing ribs 109 are provided on both sides of the width direction of the pipeline portion 108. The reinforcing ribs 109 include a plurality of reinforcing plates with a "well" cross-section, and the extension column 110 is fixed to the side walls of some of the reinforcing plates. The concentric arrangement of the extension through hole and part of the first connecting through hole 104 can ensure that the application direction of the manifold fixing member passing through the extension through hole is perpendicular to the first mounting plate 106.

[0041] It is worth mentioning that the extension column 110 is located at the corner of the reinforcing rib 109 .

[0042] Further preferably, the axial direction of the extension column 110 is perpendicular to the connecting surface of the first shell 100, ensuring that the force applied by the manifold fixing can strengthen the connection between the first shell 100 and the second shell 101 while the first shell 100 and the second shell 101 will not be subjected to displacement force.

[0043] It is worth mentioning that the connection surface of the first shell 100 is an end surface where the first shell 100 and the second shell 101 are fixed when the first shell 100 and the second shell 101 are fixed.

[0044] Further preferably, the thickness of the second mounting plate 107 is equal to the thickness of the second shell 101 .

[0045] Further preferably, the thickness of the first mounting plate 106 is smaller than the thickness of the first shell 100 .

[0046] In this embodiment, the first shell 100 is provided with a pipe portion 108, so it has a certain thickness, but the first mounting plate 106 does not need to be the same thickness as the first shell 100, and its thickness can be reduced while meeting its force requirements.

[0047] Further preferably, an overflow groove 111 is also provided on the connecting surface of the second shell 101, and the overflow groove 111 includes an annular overflow groove 111 arranged close to the outer peripheral surface of the second shell 101, and a plurality of linear overflow grooves 111 arranged in the annular overflow groove 111. The overflow groove 111 is used to receive the melted plastic in the molten welding of the first shell 100 and the second shell 101, and a partition is also provided in the overflow groove 111.

[0048] It is worth mentioning that the setting of the first connecting through hole 104 and the second connecting through hole 105 is not limited to the first mounting plate 106 and the second mounting plate 107, but connecting through holes are also provided on the first shell 100 and the second shell 101, and the linear overflow groove 111 is opened to avoid the connecting through holes on the shell.

[0049] Further preferably, the second shell 101 further includes an abutting surface abutting against the vehicle, and the connecting surface of the abutting surface and the second shell 101 are respectively located on two opposite side surfaces of the second shell 101 .

[0050] In this embodiment, the second shell 101 includes a packaging plate, one side of which is fixedly connected to the first shell 100 to achieve the molding of the pipeline, and the other side of the packaging plate is against the vehicle to achieve the installation positioning between the distribution manifold and the vehicle.
