Description

Technical Field

[0001] The utility model relates to the technical field of plastic parts, in particular to a cooling system plastic part with strong anti-shrinkage ability. Background Art

[0002] In the automotive cooling system, plastic parts are increasingly used, mainly due to the light weight, corrosion resistance, easy processing and high cost-effectiveness of plastic materials. In the automotive cooling system, the water pump is responsible for driving the circulation of coolant. Some car manufacturers choose to use special engineering plastics such as PPS (polyphenylene sulfide) to manufacture water pumps and their housings. At the same time, the automotive cooling system may also contain other shell structures.

[0003] The shell structure in the cooling system has a huge area and is usually a plate-shaped structure. Since the temperature in the cooling system varies greatly, this part of the plastic parts is prone to shrinkage due to large temperature stress, resulting in large gaps at the joints, which may affect normal use. In addition, the plastic parts may be permanently deformed and unable to recover due to frequent shrinkage changes, and need to be replaced. Therefore, in order to solve the above problems, a cooling system plastic part with strong anti-shrinkage ability is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cooling system plastic component with strong anti-shrinkage ability. The plastic component is provided with an anti-shrinkage skeleton in the plastic plate, and a complete force-transmitting skeleton is formed by the side anti-shrinkage shaft, the middle anti-shrinkage shaft and the transverse connecting shaft to share most of the temperature stress suffered by the plastic plate, thereby preventing the plastic plate from being significantly deformed. In addition, since a number of protruding connecting plates are provided on the side anti-shrinkage shaft and the middle anti-shrinkage shaft, they can generate a larger contact area with the plastic plate, so that the temperature stress suffered by the plastic plate can be transmitted to the force-transmitting skeleton through the connecting plates, thereby preventing the plastic plate portion far away from the side anti-shrinkage shaft, the middle anti-shrinkage shaft and the transverse connecting shaft from being locally and significantly deformed due to lack of support. The utility model solves the technical problem that the plastic components used in the cooling system in the prior art are prone to significant shrinkage due to greater temperature stress, making them difficult to use normally.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A cooling system plastic component with strong anti-shrinkage ability includes a plastic plate and an anti-shrinkage frame, which is buried in the plastic plate, wherein the anti-shrinkage frame includes a side anti-shrinkage shaft and a middle anti-shrinkage shaft symmetrically arranged on both sides of the side anti-shrinkage shaft, and the side anti-shrinkage shaft and the middle anti-shrinkage shaft are fixedly connected by symmetrically arranged transverse connecting shafts, in addition, a plurality of connecting plates are provided on the inner side of the side anti-shrinkage shaft, and connecting plates are provided on both sides of the middle anti-shrinkage shaft.

[0007] Through the above-mentioned structural form, an anti-shrinkage skeleton is arranged in the plastic plate, and a complete force-transmitting skeleton is formed by the side anti-shrinkage shaft, the middle anti-shrinkage shaft and the transverse connecting shaft to share most of the temperature stress suffered by the plastic plate, thereby preventing the plastic plate from being significantly deformed. In addition, since a number of protruding connecting plates are arranged on the side anti-shrinkage shaft and the middle anti-shrinkage shaft, they can generate a larger contact area with the plastic plate, so that the temperature stress suffered by the plastic plate can be transmitted to the force-transmitting skeleton through the connecting plates, thereby preventing the plastic plate portion far away from the side anti-shrinkage shaft, the middle anti-shrinkage shaft and the transverse connecting shaft from being locally significantly deformed due to lack of support.

[0008] In a possible implementation, the connection plates on the side anti-shrinkage shafts are arranged alternately with the connection plates on both sides of the middle anti-shrinkage shaft, and the connection plates on the two side anti-shrinkage shafts are symmetrical to each other.

[0009] Through the above-mentioned structural form, it can be ensured that the anti-shrinkage skeleton is a symmetrical structure as a whole, and can be in a symmetrical state when subjected to force and transmitting force, thereby avoiding the occurrence of large eccentric torque inside due to structural asymmetry, which may cause the plastic plate to twist and deform. In addition, the staggered arrangement of the connecting plates can ensure that all parts of the plastic plate can transmit force to the anti-shrinkage skeleton when receiving temperature stress.

[0010] In a possible implementation, the connecting plate is a strip-shaped plate body with a V-shaped cross section, and its opening directions are arranged toward two sides respectively.

[0011] Through the above-mentioned structural form, the contact area between the connecting plate and the plastic plate can be increased by using the V-shaped cross section of the connecting plate, so that the temperature stress can be better transmitted.

[0012] In a possible implementation, an end reinforcement plate which is also V-shaped and fits tightly is fixedly welded to the end of the connection plate, and the end of the end reinforcement plate is fixedly welded to the side anti-shrinkage shaft or the middle anti-shrinkage shaft.

[0013] With the above-mentioned structural form, since the end of the connecting plate is subjected to the largest bending moment, the end reinforcing plate can be used to strengthen the end of the connecting plate to avoid bending of the connecting plate at this location.

[0014] In a possible implementation, the side anti-shrinkage shaft and the middle anti-shrinkage shaft are both provided with a plurality of equidistantly arranged connection grooves, and the connection grooves are annular in shape and have a rectangular cross section.

[0015] Through the above-mentioned structural form, the connection strength between the plastic plate and the side anti-shrinkage shaft and the middle anti-shrinkage shaft can be enhanced by the inwardly concave connection groove, and the temperature stress can be better transferred thereto.

[0016] In a possible implementation, the side anti-shrinkage shaft, the middle anti-shrinkage shaft and the transverse connecting shaft have completely identical structures, and are all rectangular tubes with a through-length hollow groove formed in the rectangular tube.

[0017] Through the above-mentioned structural form, the overall mass of the anti-shrinkage skeleton can be significantly reduced in the form of a tubular structure, so that the weight of the entire plastic part will not increase too much.

[0018] In a possible implementation, the groove depths of the connecting grooves are equal at all locations, and the groove depth does not exceed half of the wall thickness of the rectangular tube.

[0019] The above-mentioned structural form can avoid the situation that the strength of the rectangular tube is seriously weakened due to the excessive depth of the connecting groove, which makes it easy to break at the groove.

[0020] In a possible implementation, the four inner walls of the rectangular tube are welded with centrally arranged reinforcing convex strips, and the reinforcing convex strips are the same length as the rectangular tube.

[0021] Through the above structural form, the bending resistance of the rectangular tube can be enhanced by reinforcing the convex strips, and it is also a reinforcement measure after the connection groove is opened.

[0022] In summary, the utility model includes the following beneficial technical effects:

[0023] An anti-shrinkage skeleton is arranged in the plastic plate, and a complete force-transmitting skeleton is formed by the side anti-shrinkage axes, the middle anti-shrinkage axes and the transverse connecting axes, so as to share most of the temperature stress suffered by the plastic plate and prevent the plastic plate from being obviously deformed. In addition, since a number of protruding connecting plates are arranged on the side anti-shrinkage axes and the middle anti-shrinkage axes, they can generate a larger contact area with the plastic plate, so that the temperature stress suffered by the plastic plate can be transmitted to the force-transmitting skeleton through the connecting plates, thereby preventing the plastic plate portion far away from the side anti-shrinkage axes, the middle anti-shrinkage axes and the transverse connecting axes from being locally deformed significantly due to lack of support.

DETAILED DESCRIPTION

[0030] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0031] like Figure 1 - Figure 3 As shown, the present embodiment provides a cooling system plastic component with strong anti-shrinkage ability, including a plastic plate 1, an anti-shrinkage frame 2, which is buried in the plastic plate 1, wherein the anti-shrinkage frame 2 includes a side anti-shrinkage axis 21 and a middle anti-shrinkage axis 22 symmetrically arranged on both sides of the side anti-shrinkage axis 21, and the side anti-shrinkage axis 21 and the middle anti-shrinkage axis 22 are fixedly connected by a symmetrically arranged transverse connecting axis 23. In addition, a plurality of connecting plates 24 are provided on the inner side of the side anti-shrinkage axis 21, and connecting plates 24 are provided on both sides of the middle anti-shrinkage axis 22. Through the above-mentioned structural form, the anti-shrinkage frame 2 is arranged in the plastic plate 1, and through the side anti-shrinkage axis 21, The middle anti-shrinkage axis 22 and the transverse connecting axis 23 constitute a complete force-bearing and force-transmitting skeleton, which is used to share most of the temperature stress suffered by the plastic plate 1 and prevent the plastic plate 1 from being significantly deformed. In addition, since a number of protruding connecting plates 24 are provided on the side anti-shrinkage axis 21 and the middle anti-shrinkage axis 22, they can generate a larger contact area with the plastic plate 1, so that the temperature stress suffered by the plastic plate 1 can be transmitted to the force-bearing and force-transmitting skeleton through the connecting plates 24, thereby preventing the part of the plastic plate 1 far away from the side anti-shrinkage axis 21, the middle anti-shrinkage axis 22 and the transverse connecting axis 23 from being locally and significantly deformed due to lack of support.

[0032] Among them, the connecting plates 24 on the side anti-shrinkage shaft 21 and the connecting plates 24 on both sides of the middle anti-shrinkage shaft 22 are arranged alternately, and the connecting plates 24 on the two side anti-shrinkage shafts 21 are symmetrical to each other. Through the above-mentioned structural form, it can be ensured that the anti-shrinkage skeleton 2 is a symmetrical structure as a whole, and can be in a symmetrical state when subjected to force and transmitting force, thereby avoiding a large eccentric moment inside due to structural asymmetry, which causes the plastic plate 1 to twist and deform. In addition, the staggered arrangement of the connecting plates 24 can ensure that all parts of the plastic plate 1 can transmit force to the anti-shrinkage skeleton 2 when receiving temperature stress.

[0033] like Figure 3-Figure 4As shown, the connecting plate 24 is a strip plate with a V-shaped cross section, and its opening directions are arranged toward both sides. Through the above-mentioned structural form, the contact area between the connecting plate 24 and the plastic plate 1 can be increased by the V-shaped cross section, so that the temperature stress can be better transmitted.

[0034] In addition, the end of the connecting plate 24 is fixedly welded with an end reinforcing plate 241 which is also V-shaped and tightly fitted, and the end of the end reinforcing plate 241 is fixedly welded to the side anti-shrinkage shaft 21 or the middle anti-shrinkage shaft 22. Through the above-mentioned structural form, since the end of the connecting plate 24 is subjected to the largest bending moment, the end reinforcing plate 241 can strengthen the end of the connecting plate 24 to prevent the connecting plate 24 from bending at this location.

[0035] like Figure 4 As shown, a plurality of equidistantly arranged connection grooves 25 are provided on the side anti-shrinkage shaft 21 and the middle anti-shrinkage shaft 22. The connection grooves 25 are annular and have a rectangular cross-section. Through the above-mentioned structural form, the concave connection grooves 25 can be used to enhance the connection strength between the plastic plate 1 and the side anti-shrinkage shaft 21 and the middle anti-shrinkage shaft 22, and better transfer temperature stress thereto.

[0036] Among them, the structures of the side anti-shrinkage axis 21, the middle anti-shrinkage axis 22 and the transverse connecting axis 23 are completely consistent, all of which are rectangular tubes 201. A through-length hollow groove 202 is opened in the rectangular tube 201. Through the above-mentioned structural form, the overall mass of the anti-shrinkage skeleton 2 can be significantly reduced in a tubular structure, so that the weight of the entire plastic part will not increase too much.

[0037] In addition, the groove depth of the connecting groove 25 is equal at all places, and the groove depth does not exceed half of the wall thickness of the rectangular tube 201. Through the above-mentioned structural form, it can be avoided that the strength of the rectangular tube 201 is seriously weakened due to the groove depth of the connecting groove 25 being too deep, which makes it easy to break at the groove.

[0038] At the same time, a centrally arranged reinforcing rib 203 is welded on the four inner walls of the rectangular tube 201. The reinforcing rib 203 is the same length as the rectangular tube 201. Through the above-mentioned structural form, the reinforcing rib 203 can enhance the bending resistance of the rectangular tube 201, and it is also a reinforcement measure after the connection groove 25 is opened.

[0039] The use principle and use process of this utility model:

[0040] An anti-shrinkage skeleton 2 is arranged in the plastic plate 1, and a complete force-bearing and force-transmitting skeleton is formed by the side anti-shrinkage shafts 21, the middle anti-shrinkage shaft 22 and the transverse connecting shaft 23, so as to share most of the temperature stress suffered by the plastic plate 1 and prevent the plastic plate 1 from being significantly deformed. In addition, since a number of protruding connecting plates 24 are arranged on the side anti-shrinkage shafts 21 and the middle anti-shrinkage shafts 22, they can generate a larger contact area with the plastic plate 1, so that the temperature stress suffered by the plastic plate 1 can be transmitted to the force-bearing and force-transmitting skeleton through the connecting plates 24, thereby preventing the part of the plastic plate 1 far away from the side anti-shrinkage shafts 21, the middle anti-shrinkage shafts 22 and the transverse connecting shafts 23 from being locally and significantly deformed due to lack of support.

[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
