Description

Technical Field

[0001] The utility model belongs to the technical field of electric heaters, and particularly relates to an automobile heating core body bracket. Background Art

[0002] Existing heating package installation bins are mostly integrally die-cast, but there are the following defects:

[0003] 1. Limited by the forming process, the production output is limited. In order to ensure forming and porosity, the wall thickness and structure need to increase additional dimensions and shapes, with a large boundary, which affects the applicability of the platform.

[0004] 2. Strict requirements for structure and wall thickness. On the one hand, it causes heat loss of the heating package. On the other hand, the requirements for suppliers are very high. In the case of low overall levels of technology and equipment, the qualified rate of finished products is not high and even affects the supply.

[0005] 3. Integral forming can effectively reduce costs, but it lacks platform expandability and cannot fully meet the design requirements.

[0006] 4. Low expandability and too low modularity. Adjusting the heating package solution requires remolding the middle shell, with a long cycle and high cost. Content of the Utility Model

[0007] The purpose of the utility model is to solve the above-mentioned technical deficiencies and provide an automobile heating core body bracket.

[0008] For this purpose, the utility model provides an automobile heating core body bracket, including a mounting plate. A plurality of mounting holes are opened on the mounting plate. A notch is also opened on the mounting plate. A clamping portion is arranged at the bottom of the notch. A plurality of limiting holes are opened on the side wall of the clamping portion. A heating package bin is snap-connected to the clamping portion. A clamping member is arranged at a position corresponding to the limiting holes on the heating package bin. The clamping member includes a groove opened on the side wall of the heating package bin. A movable rod is hinged in the groove. A pulley is arranged at the end of the movable rod. A spring is fixedly arranged between the movable rod and the groove. A limiting block is fixedly arranged on the movable rod.

[0009] Further, the limiting block is horizontally arranged.

[0010] Further, the heating package bin is made of a metal material.

[0011] Further, the width of the limiting block is slightly smaller than the width of the limiting hole, and the distance between the bottom surface of the limiting block and the top end of the pulley is slightly smaller than the height of the limiting hole.

[0012] Further, the projection length of the connection part of the limiting hole on the movable rod to the left end of the pulley in the horizontal direction is greater than the projection length of the limiting block itself in the horizontal direction.

[0013] The present utility model provides an automobile heating core bracket, which has the following beneficial effects:

[0014] 1. Simple mass production process: The heating package bin adopts a stamping and stretching process, and the requirements for suppliers are not as strict as those for die-castings. The bracket adopts a stamping and cutting process, and ordinary suppliers can meet the material and size requirements.

[0015] 2. No special requirements for structure and wall thickness: A thin wall thickness can increase the overall success rate. The simple structure does not impose strict requirements on suppliers, and the mass production qualification rate is high.

[0016] 3. Split assembly: When a single part fails or has problems, only this part needs to be replaced, and there is no need to replace the entire semi-finished product, resulting in low maintenance costs.

[0017] 4. High expandability: The number of heating packages can be expanded arbitrarily. Only by slightly adjusting the mold, multiple solutions can be combined. Description of the Drawings

[0023] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments to help understand the content of the present utility model. The methods used in the present utility model are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0024] As Figures 1-3As shown in the figure, the utility model provides an automobile heating core bracket, which includes a mounting plate 1. A plurality of mounting holes 2 are formed on the surface of the mounting plate 1. The mounting plate 1 is also provided with a notch 3. A clamping part 4 is arranged at the bottom of the notch 3. A plurality of limiting holes 6 are formed on the side wall of the clamping part 4. A heating pack bin 5 is snap-connected to the clamping part 4. A clamping member 12 is arranged at a position corresponding to the limiting hole 6 on the heating pack bin 5. The clamping member 12 includes a groove 7 formed on the side wall of the heating pack bin 5. A movable rod 8 is hinged in the groove 7. A pulley 10 is arranged at the end of the movable rod 8. A spring 11 is fixedly arranged between the movable rod 8 and the groove 7. A limiting block 9 in the horizontal direction is fixedly arranged on the movable rod 8.

[0025] The heating pack bin 5 is made of metal material, with low thermal resistance and high thermal conductivity coefficient, which can effectively transfer the heat of the heating pack and increase the power of the PTC; it is corrosion-resistant and meets salt spray tests and other corrosion tests; it has high strength and can protect the heating pack under working conditions such as vibration or other collisions.

[0026] As Figure 4 shown, the width of the limiting block 9 is slightly smaller than the width of the limiting hole 6, and the distance between the bottom surface of the limiting block 9 and the top end of the pulley 10 is slightly smaller than the height of the limiting hole 6, so as to ensure that the heating pack bin 5 does not move or displace after being installed on the mounting plate 1. The projection length L1 in the horizontal direction from the connection of the limiting hole 9 on the movable rod to the left end of the pulley 10 is greater than the projection length L2 of the limiting block 9 itself in the horizontal direction, so as to ensure that when the clamping member 12 slides on the clamping part 4, due to the overlong limiting block 9, the limiting block 9 abuts against the bottom surface of the clamping part 4, resulting in the heating pack bin 5 being unable to move upward continuously. The setting of the pulley 10 can play a buffering role through the sliding of the pulley 10 itself when the clamping member 12 comes into contact with the clamping part 4, and the clamping member 12 can be clamped with the limiting hole 6 only by the rotation of the pulley 10 without other interventions.

[0027] During use, align the notch 3 with the position of the heating pack. Fix the mounting plate 1 on the water tank through the mounting holes 2. Move the heating pack bin 5 upward along the clamping part 4. After the pulley 10 on the clamping member 12 contacts the clamping part 4, it is squeezed by the clamping part 4, the spring 11 is compressed, and the movable rod 8 moves towards the groove direction. Further, the heating pack bin 5 can continue to move along the clamping part 4. When the clamping member 12 moves to the position of the limiting hole 6, the movable rod 8 is no longer squeezed by the clamping part 4, the spring 11 resets the movable rod 8, and the limiting block 9 is clamped into the limiting hole 6 to complete the installation of the heating pack bin 5.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left", "right", "upper", "lower", "top", "bottom", "front", "rear", "inner", "outer", "back", "middle", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0029] However, the above are only specific embodiments of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of patent protection of the present utility model, should still fall within the scope covered by the claims of the present utility model.
