Description

Technical Field

[0001] The utility model belongs to the field of forklift battery packs, and in particular relates to a protective shell for a forklift battery pack. Background Art

[0002] The protective shell of a forklift battery pack is an outer shell or outer covering used to protect the battery pack. Its main purpose is to provide additional protection to prevent damage or contamination of the battery pack by the external environment. The protective shell is usually made of durable materials such as plastic or metal, with high wear resistance, corrosion resistance and impact resistance. It can cover the entire battery pack or specific parts, such as battery cells and connectors.

[0003] For example, a Chinese patent publication numbered CN220116148U points out a battery pack protection structure for an electric forklift. In the cited document, the battery pack body moves in the inner cavity of the mounting shell. When the ball rolls inside the arc groove, the moving plate moves, and the battery pack body can be pulled out of the inner cavity of the mounting shell. The operation is simple and fast, and the friction of the battery pack body moving in the inner cavity of the mounting shell is reduced, thereby facilitating the removal of the battery pack body, shortening the battery pack replacement operation time, and improving the battery replacement efficiency.

[0004] In actual use, although the above cited patent has achieved the rapid removal of the battery pack body, it still has certain limitations in use, that is, the battery pack in the document lacks clamping and shock-absorbing protection for the battery pack body during installation. Since the forklift will face bumps, vibrations and impacts when working, these will have an adverse effect on the battery pack; the battery pack without shock-absorbing treatment is susceptible to external impact, resulting in damage to the internal structure and connectors of the battery, and even causing damage to the battery cell. This may cause the battery capacity to decrease, the life to be shortened, or it cannot work properly. At the same time, the battery protection in the cited document also lacks heat dissipation treatment. Therefore, a protective shell for a forklift battery pack is proposed to solve the above problems. Utility Model Content

[0005] In view of one or more of the above defects or improvement needs of the prior art, the utility model provides a protective shell for a forklift battery pack, which has the advantages of being able to perform shock-absorbing installation on the battery pack body and heat dissipation treatment on the inside of the battery protective shell.

[0006] To achieve the above-mentioned purpose, the utility model provides a protective shell for a forklift battery pack, comprising a battery protective shell; a sealing cover is embedded on the upper part of the battery protective shell;

[0007] The battery protection housing is rectangular and has an open top. The battery protection housing forms a receiving cavity for receiving a battery pack. Two moving components are assembled in the receiving cavity, and two support plates are arranged between the two moving components. One of the support plates is slidably assembled on the moving component.

[0008] A number of support columns are supported on the sides of the two support plates. A connecting beam is supported on the number of support columns. A rubber mounting plate is supported on the connecting beam. A number of shock absorption components are arranged horizontally along the opposite sides of the two rubber mounting plates.

[0009] As a further improvement of the present utility model, the shock absorption component includes a positioning seat arranged on the side of the rubber mounting plate. A shaft rod is arranged on the side of the positioning seat. A sleeve rod is slidably arranged outside the shaft rod. A positioning block is connected to the side of the sleeve rod.

[0010] As a further improvement of the present utility model, a compression spring is sleeved outside the shaft rod and the sleeve rod. One end of the compression spring is connected to the positioning seat, and the other end is connected to the positioning block.

[0011] As a further improvement of the present utility model, a number of notches are formed horizontally on the support plate, and heat dissipation fans are assembled in the notches.

[0012] As a further improvement of the present utility model, the moving component includes an adjustment seat arranged in the battery protection housing. A groove is formed in the adjustment seat, and a sliding seat is slidably arranged in the groove. The sliding seat is arranged in a T shape. A sealing plate is arranged on the side of the adjustment seat. A groove is formed between the adjustment seat and the sealing plate for the sliding seat to slide. Both ends of one of the support plates are installed between the sliding seats in the two moving components.

[0013] As a further improvement of the present utility model, a reciprocating motor is further arranged in the adjustment seat. The output end of the reciprocating motor is connected to a lead screw. A sliding sleeve seat is meshed outside the lead screw. The sliding sleeve seat is connected to the sliding seat.

[0014] Generally speaking, compared with the prior art, the beneficial effects of the above technical solutions conceived by the present utility model include:

[0015] In actual use, when the external impact is transmitted to the support plate, the rubber mounting plate can first absorb the impact force through the sliding installation between the shaft sleeve rod and the shaft rod, and the remaining impact force will compress the positioning block, and then the impact force is secondarily absorbed by the deformation of the positioning block until the impact force is greatly reduced. In combination with the clamping and buffering of the battery pack by a number of shock absorbing components, the impact force on the battery pack between the two abutting plates can be greatly reduced. Compared with the direct clamping of the battery pack in the cited documents, the present application can effectively reduce the transmission of vibration and impact to the battery pack body by adding two sets of shock absorbing components, thereby reducing the impact on the battery pack body.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] Depend on Figures 1-4 A protective shell for a forklift battery pack is provided, comprising a battery protective shell 1; a cover 2 is embedded on the upper side of the battery protective shell 1;

[0024] The battery protection housing 1 is rectangular and has an open top. The battery protection housing 1 forms a receiving cavity for receiving a battery pack. Two moving components 3 are assembled in the receiving cavity, and two support plates 4 are arranged between the two moving components 3. One of the support plates 4 is slidably assembled on the moving component 3.

[0025] A number of support columns 6 are supported on the sides of the two support plates 4. A connecting beam 61 is supported on the number of support columns 6. A rubber mounting plate 7 is supported on the connecting beam 61. A number of shock-absorbing components 8 are arranged horizontally on the opposite sides of the two rubber mounting plates 7.

[0026] In this embodiment, in actual use, the moving component 3 can be used to drive the movement of the support plate 4. When the battery pack body is between the two abutting plates 9, the user drives the support plate 4 to move until the abutting plate 9 on the support plate 4 tightly abuts against the other side of the battery pack. When an external impact is transmitted to the support plate 4, through the sliding installation between the sleeve rod 83 and the shaft rod 82, the rubber mounting plate 7 can first absorb the impact force, and the remaining impact force will compress the positioning block 84, and then the deformation of the positioning block 84 is used to absorb the impact force twice until the impact force is greatly reduced. With the clamping and buffering of the number of shock-absorbing components 8 on the battery pack, the impact force received by the battery pack between the two abutting plates 9 can be greatly reduced. Compared with the direct clamping of the battery pack in the cited document, the two additional shock-absorbing components 8 in this application can effectively reduce the transmission of vibration and impact to the battery pack body and reduce the impact on the battery pack body.

[0027] Specifically, referring to Figures 1-3 , the shock-absorbing component 8 includes a positioning seat 81 arranged on the side of the rubber mounting plate 7. A shaft rod 82 is arranged on the side of the positioning seat 81. A sleeve rod 83 is slidably arranged outside the shaft rod 82. A positioning block 84 is connected to the side of the sleeve rod 83.

[0028] In this embodiment, through the sleeving between the arranged positioning seat 81 and the shaft rod 82, when an external impact hits the rubber mounting plate 7, the arranged rubber mounting plate 7 can first absorb the impact force initially, and then transmit it to the positioning seat 81. At this time, the arranged shaft rod 82 can slide into the sleeve rod 83.

[0029] Specifically, referring to Figures 1-3 , a compression spring 85 is sleeved outside the shaft rod 82 and the sleeve rod 83. One end of the compression spring 85 is connected to the positioning seat 81, and the other end is connected to the positioning block 84.

[0030] In this embodiment, when an impact force impacts the rubber mounting plate 7 and causes the shaft rod 82 to slide into the sleeve rod 83, the positioning block 84 disposed outside the shaft rod 82 can be compressed and thus deformed. After the deformation of the positioning block 84, the external impact force can be sequentially absorbed by the battery protection housing 1, the rubber mounting plate 7, and the positioning block 84, thereby greatly reducing the impact of the impact force on the battery pack within the battery protection housing 1, and effectively reducing the damage of the battery pack.

[0031] Specifically, referring to Figures 1-2 , a plurality of notches are formed in the transverse direction of the support plate 4, and heat dissipation fans 5 are assembled in the notches.

[0032] In this embodiment, through the notches in the support plate 4 provided, the heat dissipation fans 5 can be installed. At this time, the user connects the heat dissipation fans 5 to a power source to drive the provided heat dissipation fans 5. In a preferred embodiment, air inlets are provided on the outside of the battery protection housing 1 for the heat dissipation fans 5 to extract wind. Since heat is generated during the operation of the battery pack, if effective heat dissipation cannot be achieved, it may cause the battery pack to overheat, affecting the battery performance and lifespan. By providing multiple groups of heat dissipation fans 5 on the support plate 4, the air flow within the battery protection housing 1 can be increased, accelerating the conduction and dissipation of heat, improving the heat dissipation efficiency. The heat dissipation fans 5 can blow air to discharge the hot air from the inside of the battery protection housing 1 and at the same time bring in fresh cold air. This can effectively reduce the temperature of the battery pack, keep it within an appropriate operating temperature range, and improve the safety and stability of the battery.

[0033] Specifically, referring to Figure 4 , the moving assembly 3 includes an adjustment seat 31 disposed within the battery protection housing 1. A groove is formed in the adjustment seat 31 and a sliding seat 33 is slidably disposed therein. The sliding seat 33 is in a T shape. A sealing plate 32 is provided on the side of the adjustment seat 31, and a groove is formed between the adjustment seat 31 and the sealing plate 32 for the sliding seat 33 to slide. Both ends of one of the support plates 4 are installed between the sliding seats 33 within the two sets of moving assemblies 3.

[0034] In this embodiment, during actual use, the provided sliding seat 33 can slide between the adjustment seat 31 and the sealing plate 32. At the same time, the groove formed between the adjustment seat 31 and the sealing plate 32 can linearly limit the sliding seat 33, preventing the sliding seat 33 from flipping, and thus ensuring the smooth linear operation of the sliding seat 33.

[0035] Specifically, referring to Figure 4 , a reciprocating motor 34 is further provided within the adjustment seat 31. The output end of the reciprocating motor 34 is connected to a lead screw 35. A sliding sleeve seat 36 is meshed with the outside of the lead screw 35, and the sliding sleeve seat 36 is connected to the sliding seat 33.

[0036] In this embodiment, during actual use, by connecting a power supply to two reciprocating motors 34, the reciprocating motors 34 can drive the lead screw 35 to rotate. Limited by the regulating seat 31 and the sealing plate 32, at this time, the sliding sleeve seat 36 engaged with the outside of the lead screw 35 will drive the sliding seat 33 to move linearly along the stroke range of the lead screw 35, thereby driving one of the support plates 4 to move towards the other support plate 4.

[0037] The protective shell for the forklift battery pack of the present utility model:

[0038] First step: During actual use, place the battery pack between two support plates 4, and make one of the abutting plates 9 abut against one side of the battery pack. Subsequently, drive the two moving components 3 to drive the support plates 4 to move.

[0039] Second step: By connecting a power supply to two reciprocating motors 34, the reciprocating motors 34 can drive the lead screw 35 to rotate. Limited by the regulating seat 31 and the sealing plate 32, at this time, the sliding sleeve seat 36 engaged with the outside of the lead screw 35 will drive the sliding seat 33 to move linearly along the stroke range of the lead screw 35. Through the installation between the two sliding seats 33 and the support plates 4, one of the support plates 4 assembled between the moving components 3 can slide towards one side of the other support plate 4.

[0040] Third step: The user drives the support plate 4 to move until the abutting plate 9 on the support plate 4 tightly abuts against the other side of the battery pack. At this time, with the cooperation of the two abutting plates 9 to clamp and protect both sides of the battery pack, when an external impact is transmitted to the support plate 4, through the sliding installation between the sleeve rod 83 and the shaft rod 82, the rubber mounting plate 7 can first absorb the impact force, and the remaining impact force will compress the positioning block 84. Furthermore, the deformation of the positioning block 84 is used to absorb the impact force secondly until the impact force is greatly reduced. With the cooperation of several shock absorption components 8 to clamp and buffer the battery pack, the impact force received by the battery pack between the two abutting plates 9 can be greatly reduced.

[0041] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
